Jacking system of the present utility model be summarized as 3 interrelated but also can use separately or the system such as flexible combination configuration forms, be described below:
The first Weighting system:
(please refer to schematic diagram 1.Because this figure is axonometric drawing, the overlapping signal of some local front and back position is unclear, please refer to plane generalized section 2, Fig. 3, Fig. 4)
Native system is in order to utilize common people's physical efficiency with the hands to apply easily the characteristics of 20-30kg downforce, to store up the energy of certain lifting loading by this system; And because this system is directly to lie in base plate, thereby be the basic framework (select other system as cited below and while not adopting native system, this basic boom need retain and engages for other system, or apply application force carry out the lifting base plate) of whole system.
It comprises the first rotating shaft (3), the first weight member (1), base plate (5); Wherein, the first rotating shaft is provided with the first switch (9) turned to for setting the first rotating shaft, and the first fixed pulley (2a-2f); The first weight member is positioned at an end of the first fixed pulley hoist cable (4); Base plate is positioned at the other end of the first fixed pulley hoist cable and synchronizes and counter motion with the first weight member.
The weight block that the first weight member is definite shape, consider the earth excavation amount in practical application, should select the proportion material that large but cost is moderate as far as possible as cast iron or lead, and the shape of making cuboid is to save space, its effect is to offset part or all of loading by the first fixed pulley, in descending process, base plate is simultaneously up under Action of Gravity Field for the first weight member.Generally need during the selecting of its weight to consider that the ordinary people press down the operation more easily of 20-30kg left and right.Certainly also can consider the 50-70kg numerical value of whole people's weight for some other special application, be also feasible.What consider in addition is whether former weight is arranged while using, as purposes be the instrument of depositing 30kg, the counterweight of 30+20=50kg can use, if but the device of this purposes of picture sewage disposer, per week need to be pressed onto the very light empty bucket of conducting oneself with dignity underground, and the counterweight of 50kg is just more painstaking.More example please refer to practical example.
In this system, the first fixed pulley has two kinds of ways: 1, for pair of sprocket (2a, 2b), coordinate another group sprocket wheel (2c, 2d, 2e, 2f); 2, pair of sprocket (2a, 2b) coordinates another to rope sheave (2c, 2d, 2e, 2f).Two kinds of ways all lift four jiaos of base plates, maintenance level while making base plate increase.Can be by the scheme of rope sheave for Cost reduction in enforcement, but at least need with the setting of pair of sprocket left and right symmetrically, guarantee walk about up and down in process can not produce the deviation of slip and make counterweight and base plate out-of-level.
According to requirements, the base plate of this system can be and separates with the container of carrying on it, also can make an integral body with container, and hoist cable directly is fixed on to bottom (as embodiment 2).
In this system, the first switch can be, controllable bidirectional ratchet for example, and for setting turning to of the first rotating shaft, these parts can be realized by existing other technology.Signal Figure 11, for a kind of scheme wherein, it controls button (is the soft rubber button, middle is hard plastic) be arranged on the stretcher of the first external force application system, make it promote poke rod (27) and to relevant position, cause it can only turn toward a direction (in figure shown in arrow), with realization, use by the key control base plate and can rise or the sinking state.
The second Weighting system:
Another system of the utility model, it comprises: the second rotating shaft (14), and the second fixed pulley (2); The second weight member (10), it is positioned at an end (the hoist cable other end is weight 13) of the second fixed pulley hoist cable (11), be suspended to the below of the first weight member (1) by the perforation (25) through on the first counterweight, it comprises while contacting with the first weight member and the arrangement of clutch (21) of its combination; Drive at every turn rise the second External Force Acting device of certain altitude of the second weight member under the second External Force Acting, it comprises: second face (20 of exerting pressure, can be connected with cover), the second depression bar (19) under it, the large unidirectional drive flywheel (17) meshing with it, little drive wheel (16) with large unidirectional drive flywheel coaxial (25) socket, with little drive wheel meshing, be fixed on the driven gear (15) in the second rotating shaft, and coaxial with big or small drive wheel, set the second sense-finding switch (18, be also the controllable bidirectional ratchet) that the second Weighting system turns to.
This system is in order to supplement the total weight of counterweight, can to promote heavier loading.It is the principle by lever that the second weight member rises, and can do light operation and store up energy unconsciously by one hand.When the second counterweight goes upward to after the first weight member contacts, be connected with the first weight member by arrangement of clutch, and promote base plate by the first fixed pulley together with the first weight member.Selecting with the first counterweight in like manner of its shape and material.The laborsaving moment of the part of the second external bringing device is to realize between the impeller diameter ratio of big or small drive wheel, and (referring to Figure 10) realized in the position of the pressure that the laborsaving moment of another part can be by regulating depression bar.According to lever principle, total laborsaving distance risen of catching up with is inversely proportional to, and more laborsaving in other words, the distance of rising is shorter, and the number of times that lifting need to be exerted pressure is more.Because the second weight member is the weight possible according to actual contents etc. and fixed, therefore, big or small drive wheel impeller diameter ratio, depression bar upper lever torque ratio and promote exert pressure number of times etc. of the required hypothesis of height overall and need to comprehensively calculate decision.
The second switch of this system is the same with the first switch, for example be bidirectional ratchet (principle of work, with the first switch, please refer to Figure 11-12), for setting turning to of the second rotating shaft, for example the second counterweight is when up, and the second rotating shaft can only left-hand revolution (from the right side to the left); When sewage disposer is descending, the second rotating shaft can only clickwise.
Control reason that this system turns to second switch to be located at (and not being located in the second rotating shaft) on drive wheel and be direction that two live axles turn just with the opposite direction in the second rotating shaft, thereby the direction that second switch need be stirred is identical with the direction of controlling depression bar and the clutch of large driving flywheel, is convenient to arrange interlock sleeve (a 28) synchro control.Please refer to schematic diagram 5 and 7(annotates: in the large flywheel back that drives, clear for illustrating because of the second pole changer, Fig. 5-9 see for from left to right, and the signal that turns to that each is taken turns need corresponding change.) the large driving flywheel of this system is in working order the time, is with the depression bar contact.Depression bar is mentioned and should be driven greatly flywheel all and then to turn while pressing down in other words, but, because it is flywheel (single direction ratchet), while mentioning, with axis, partly skids, inoperative; Ordering about the live axle conter clockwise while pressing down turns and (sees from left to right, now second switch must push the position that allows the live axle conter clockwise to turn), with little drive wheel also conter clockwise, turn, little drive wheel drives flower wheel and the second rotating shaft cw turns, thereby up walks a segment distance with the second counterweight.When the second counterweight can not press down with depression bar after the first counterweight engages again, now need depression bar is pushed away to large drive wheel, and interlock sleeve (28) is stirred the position that second switch to cw turns, while making to need to promote loading no longer with stirring this switch to simplify the operation.Fig. 8 is the detail design that the depression bar lower end is buckled in depression bar vessel faces exit position, and depression bar draw-in groove (31) is tipped the action of the outlet edge sleeve that also can promote to link in and made second switch be in appropriate location, simplifies and opens after cover the operation of rising load.
In this system, the effect of the arrangement of clutch of the second weight member is to be pulled up to while contacting with the first weight member when the second weight member, is connected with it, thereby can promotes heavier carrier so that the gravitation energy of the first weight member is added to the second weight member.The bottom of the first weight member is provided with can be by groove or the projection (26) of device interlock on the second counterweight.The arrangement of clutch designing requirement be when container bottom power-transfer clutch in released state, like this when being depressed into when bottom, a pull-up the first counterweight to base plate; And it leaves when bottom, arrangement of clutch is in running order, thereby just can fasten when the groove bottom touching the first counterweight or projection (26).Arrangement of clutch can be realized by the kinds of schemes of prior art.Fig. 7 is power-transfer clutch mode of operation exploded drawings (1-4); Schematic diagram 8-9 is two kinds of arrangement of clutch schemes, all utilizes the deadweight of the second counterweight to make power-transfer clutch pliers fixture or embolus pinch in when bottom, and while leaving bottom, it is in running order under the effect of spring.
The first external force application system:
Referring to Figure 19-24.
The 3rd system of the present utility model.This external force application system be when the contents that need to promote very heavy, during the load of total counterweight of first and second on can not the pull-up base plate, provide for example use of foot-operated auxiliary its rising of power of extra power; Need to can also be by the situation of this external force application system: the second Weighting system breaks down, when light is not enough to the loading of pull-up base plate with the first counterweight, maybe when selecting the external force application system to be unique lifting means for reducing the cost.
This system comprise the first press surface (6, stretcher), with the first depression bar (7) be connected under the first press surface, with the first unidirectional flywheel (8) of the first depression bar engagement, the first unidirectional flywheel sleeve is connected to (3) in the first rotating shaft.This first external force is by acting on the first coaxial unidirectional flywheel of the first fixed pulley and driving chain the base plate pull-up with the tooth pressure bar under stretcher.When stretcher does not have pull-up, following depression bar and the first unidirectional flywheel are released state, make it not affect pressing down and lifting operation base plate; When pressing button (35 of Figure 10, center is hard plastic, periphery is the button of caoutchouc), pedal gim peg (36) is separated with pedal (6), then pull-up pedal front end, pedal is pulled by the tension spring in device, makes foot-operated trailing edge slide into rotary axis groove (34), and merchandiser is meshing to flywheel simultaneously for depression bar.Catch up with and state the second counterweight external force application system in like manner, the first depression bar when up and the first rotating shaft skid, and the first depression bar orders about the first rotating shaft left-hand revolution (from the right side to the left) when descending, and then drive the first fixed pulley left-hand revolution, make base plate and carrier up.It should be noted that in addition, the usage condition of the first External Force Acting device is the first switch (for the controllable bidirectional ratchet) but is set as allowing the first rotating shaft left-hand revolution not turn by cw, use before foot-operated and need by " risings " button (Figure 19-22) on it, so base plate and upper load thereof are along with foot-operated firmly segmentation rising and can not falling back back again and again.
Three partial devices of the present utility model can all adopt becomes a set of complete solution easily, also can select even separately and use by practical application and cost budgeting requirement independent assortment.
Use does not have the combination of the first Weighting system or separately need do some corresponding adjustment during operational version, as: while adopting the second Weighting system, some members of originally being combined with the first counterweight, as the supporting wheel of difference and its sense-finding switch of controlling the first rotor shaft direction that drives the base plate rising in arrangement of clutch, the first rotating shaft all must retain and could use; While using the first external force application system, some members of originally being combined with the first counterweight, the supporting wheel of difference and its sense-finding switch of controlling the first rotor shaft direction that the first rotating shaft and upper drive base plate thereof rise all must retain and could use, and do not use the first Weighting system in fact can only the first weight member.And select or do not select a system, its different function that can make scheme possess.As: do not adopt the first Weighting system, loading is added to and will directly sinks to bottom of device on base plate and not need to press down; Adopt the second Weighting system in theory great loading can join, then the design by moment realizes that the ability of repeatedly action stores up the loading pull-up; Adopting the first external force application system is also to realize by the configuration of moment the lifting to different loadings; And adopt separately the scheme of the first Weighting system, mixing to be less than lifting of people and to press down maximum, force with the positive minus tolerance of using loading and counterweight just makes scheme have availability, be that the people uses maximum pressure or the hoisting force that can apply, the auxiliary force of giving in conjunction with counterweight, just can compress into or propose ground to the loading in application.After combination, its function and characteristic have just superposeed, and each configuration feature that please refer to practical example 1 is described.
Jacking system of the present utility model is placed in two-layer housing and (considers anticorrosion and cost, plan is done by hard plastic), comprising body skin (contacting with underground earth) and inner housing, for base plate or container lifting therein, and two housings itself is also the support of each device of the utility model.Can configure the carrying framework by various operatings needs on base plate, as collection foreign material and cupboard or the shelf of instrument, the container that takes up solid or liquid and sewage disposer.
The flexible sewage disposer of provided with wheels of one of important application that the utility model comprises (being its original application conception):
This sewage disposer is that two-section staving in the roughly same height is formed by connecting, and upper bucket (40) is wide, and lower bucket (41) is narrow.Figure 12 is flexible sewage disposer just, the External view after the back of the body, side and contraction.Be the belt wheel sewage disposer of calibrated altitude during elongation, for the standard waste-skip, carry and turning over; The width of bottom two wheels (45) will take in down and cut in ladle body, cuts down away Shi Buhui on while making to shrink to be withstood by wheel.While needing the elongation sewage disposer, the both sides of two portable sewage disposers are carried on slightly exerting oneself, the rubber band (47) of the engagement edge of upper and lower bucket can be forced tightly (referring to Figure 15), and then the strainer spanner (44) at diagonal angle on engagement edge being pulled just can be the fastening (Figure 14) of upper and lower bucket; Operation during contraction is contrary.
The purpose of this setting is with the characteristic of using number of days to increase because of the sewage disposer rubbish amount of hoarding, can coordinate the quantity of refuse staving that stretches, and can make sewage disposer energy Hide All or partly be hidden in underground, thereby reach the function of beautifying the appearance of the city, but can reduce the digging depth of sewage disposer jacking system.More particularly, be exactly harvest rubbish at every turn after, the user receives sewage disposer short, being pressed onto the degree of depth only has in the jacking system of common sewage disposer mid-height and entirely buries, (cover and sewage disposer are stamped clasp (46) and fasten pull-up simultaneously to throw away rubbish with regard to the cover of heaving mechanism every day afterwards, please refer to signal Figure 16), and close the potential energy (attention, owing to highly reducing by half, needs the number of times of gland also to reduce by half) of the second counterweight that the action of cover stores up by pressures; When the inadequate capacity of sewage disposer, at first to be careful and see whether the second counterweight has fastened with the first counterweight, if also do not have, need press many its fastenings that allow under several to cover, the clasp of the cover button to dustbin cover separates, and depression bar pushes away drive wheel (the interlock sleeve also is located at the state that can walk down to the second counterweight), and the pull-up cover becomes plumbness, then the sewage disposer that stretches, capacity to do has just doubled.While by the time receiving rubbish, press the pole changer of controlling in the first rotating shaft, sewage disposer is just gone up ground automatically next time.Repeat the top operating cycle after harvesting rubbish.
Its leading edge of the design of cover of sewage disposer adopts the size of the belt wheel sewage disposer of standard, but upper cover need be as far as possible thin, and being beneficial to that the jacking system ground segment falls in can be too not dark, and easily configures corresponding double water proof structure; And bung design is upper, outside meeting functional requirement, the image of the rubbish shoot of attempting to break traditions; (43, Figure 13) design of position must consider after waterproof and bung to turn over the needs of 270 ° to the lid hinge, and the needs of the handgrip (48) used of push-and-pull.Please refer to being explained in more detail in specific embodiment embodiment 1.

The specific embodiment
As shown in the figure, the present embodiment provide a kind of jacking system for the resident the belt wheel sewage disposer of standard, or the telescopic belt wheel sewage disposer that the utility model provides collects into ground, realizing beautifying the city streets increases the purpose of usage space.
Jacking system uses the integrated application of 3 above-mentioned systems.Wherein the first counterweight is the 30kg ironcasting, is more than 20 kilogram of pressure considering that the ordinary people can apply easily, adds that the deadweights such as the sewage disposer of 10 kilograms and base plate can compress into underground easily to sewage disposer.The second counterweight adopts the 25kg ironcasting, is to consider that total counterweight is the lifting needs that 55kg can meet general every city dweller's rubbish total amount weekly.The configuration of external force application system is to use for garbage weight once in a while exceeds when total counterweight 55kg can start the limit of its rising, as the rubbish total load is that 60kg(comprises base plate sewage disposer deadweight etc.) time, load and counterweight are poor is 60-55kg=5kg, surpasses 5kg by the foot-operated power be added on the first Weighting system chain and just can promote sewage disposer.
Configuration, the accessory of all aforesaid each systems all are suitable for.The more detailed setting is described as follows in addition:
During use, as aforementioned, when bringing back the sky sewage disposer, ' decline ' button that need to press on stretcher is pressed onto bottom of device to empty bucket again; Need to arrange bung depression bar (toward post-tensioning) simultaneously and make its in running order and buckling device cover and dustbin cover (46).Then the use of every day, throw away the action of rubbish open-and-close cover just at the energy that stores up the second counterweight.
It should be noted that, when promoting sewage disposer, need to first open extremely approximately 90 degree positions of cover, now, if the second weight member not yet rises to most significant bit while engaging with the first weight member, at this moment need many foldings cover to allow several times it rise to most significant bit and be combined with the first weight member.If do not do like this, stir second switch and directly promote inward the depression bar sleeve 28 that can make to link, make the second weight member sink to bottom of device, thereby also make second counterweight in this operating cycle lose effect.
When needs promote sewage disposer, the clasp of cover and the inside dustbin cover is broken away from, cover is dug to about 90 ° of positions, the depression bar termination is stuck in to the depression bar exit position, then by the flexible glue button of ' rising ' on the stretcher of the right, the first sense-finding switch under its button is dialled bar and is pushed to propradation, at this moment, if total total loading of counterweight energy pull-up, sewage disposer just slowly rises from ground.Not so, the pull-up stretcher also can be gone up sewage disposer come by some external force.
The design of stretcher has also considered that the operation of interlock is to simplify use.When usually pedal keeps flat, needing toward post-tensioning and pressing under foot-operated leading edge have in the groove of clasp, the depression bar under position at this moment makes to ride and the passive divided flywheel in the first rotating shaft from.At needs, sewage disposer is compressed into when underground like this, having pressed ' decline ' flexible glue button on the stretcher stirs bar to sense-finding switch and is pushed into can allow under base plate the time, need not consider again depression bar is pulled open with passive divided flywheel from (not so, pressing down sewage disposer can play and be fastened and make sewage disposer press not go down by it foot-operated), reduce Operating Complexity.It is simplified design that the button of ' rising ' and ' decline ' is placed on stretcher to one, also in order to facilitate waterproofing design.
These examples of implementation can be used the belt wheel sewage disposer of general standard, the flexible sewage disposer that also available the utility model provides.。Please refer to the explanation of the second external force application system of the second Weighting system, and the mark of Fig. 5 D, we estimate moment and working effect in these given several supposition sizes:
With
represent diameter, suppose
with
border line to power, equate; If
with
the wheel footpath is 130mm and 38mm, and impeller diameter ratio is:
Arm of force L
1/ L
2=900mm/760mm=1.184/1
Two moment ratios are superposed to: 3.4x1.184=4.0
Be P
1pressure be 1/4 of the second counterweight, i.e. 25kgx1/4=6.25kg;
Because of distance and laborsaving being inversely proportional to of rising, the height that the second counterweight rises is P
1press down 1/4 of length, suppose each pull-up 600mm height, the second counterweight rises the height of 150mm, the rise of 7 days is highly 7x150=1050mm, the chances are our jacking equipment height of needing with the standard sewage disposer, the actual number of times and highly have difference of uncapping used, but such configuration probably meets the requirement that the energy that unconsciously uses operation handlebar the second counterweight in we stores up in a week, add the first counterweight, just can meet the needs that we promote sewage disposer each week; While using flexible sewage disposer, counterweight is all the same with all accessories, but the degree of depth of its jacking system approximately only has half, the rise of the second counterweight highly also subtracts half, mean that the number of times that presses down that makes the second counterweight rise to extreme higher position also reduces by half, basically need not add in addition in other words opening and closing movement and just can before the elongation sewage disposer, (pressure surface covers again afterwards) allow two counterweights engage.
It is a kind of optimal configuration that 3 germline unifications of the present embodiment are reinstated, also be to provide a kind of scheme that can process the quantity of refuse of peak load, therefore can be used in this configuration in the larger heavier application such as TRADE REFUSE bucket or the heavy especially container as garden carrying rainwater or fertilizer of carrying etc.In concrete application, this sinking-type dustbin device can adopt any one of 3 systems or the combination of two to meet user's requirement from different paying ability to different use habits.Be described below respectively (the general characteristic description that this is also the different allocation plans of each system of the present utility model):
1, being the most also that cost is minimum, is exactly only to use the first Weighting system.Add that by the counterweight of 30kg the pressing down with hoisting force of 20-30kg that the ordinary people can apply estimate, such system also can be dealt with general city dweller's each household rubbish consumption weekly and promote needs, because the about 30kg of the total loading of the quantity of refuse of common a week, if be less than 30kg, sewage disposer itself just can be gone up ground automatically; Even if the heavier situation of 50kg, the ordinary people also can, after the 30kg counterweight is offset a part of weight, just can be brought up rubbish by the power of 20kg.Thereby this is more cheap but feasible scheme.
2, with the first and second Weighting systems, be combined with.This situation is that the 20-30kg that 55kg adds the ordinary people lifts power because of total weight, can promote the rubbish loading of 75-85kg, in a lot of local governments, there is regulation not allow the resident to put under the situation of too heavy rubbish, therefore the chance that in fact needs the external force application system is 0, and this configuration is the ideal scheme of cost compare when moderate.
3, by the independent scheme of the second system, (annotate: all schemes that do not adopt the first Weighting system, the arrangement of clutch engaged with the first counterweight, the tractive base plate gear structure of the first counterweight, the basic boom of the first configuration of pole changer etc. needs to retain, and just the first weight member is made into to weight).This scheme can be removed the operation that presses down sewage disposer from, and empty sewage disposer also can sink to underground automatically, then throws away the pass lid action of rubbish every day and stores up energy to promoting sewage disposer use.Certainly, here we can counterweight any counterweight, as 30-40kg, but the corresponding gland number of times of wanting a little bigger, total lifting to need of the pressure needed is also wanted multiple spot, thereby need carefully consider and elect.
4, the second counterweight and external force application system in conjunction with application scheme.This situation is similar with the 3rd scheme, but many stretchers in support, to promote heavier load.
5, use separately the external force application system.Such configuration is simple, cost compare is low, is also that sewage disposer can sink to automatically underground, and while promoting to needs, the pull-up stretcher steps on sewage disposer come just can.Utilize the principle of lever to add when foot-operated that, than the power that is easier to apply human body tens kilogram weights, this scheme can be designed to promote heavier load.Shortcoming is that operation is slow.
6, external force applies the scheme of applying of being combined with the first counterweight.This scheme need press down the action of sewage disposer to store up certain energy, and while then needing to promote, the pull-up stretcher helps to promote.Be also when foot-operated than the power that is easier to apply human body tens kilogram weights, this is also the scheme that can promote heavier load.
Above all schemes in, the user can oneself lift sewage disposer with certain power, need only to follow the power of counterweight to add up over loading (light with the external force application system time counterweight be 0), can be brought up sewage disposer.
Family expenses foreign material storage cabinet
This application example can be the various household foreign material storage of purposes.Because regularly not uncapping action, can not add the second counterweight, with regard to the first counterweight with simple least cost.Its counterweight can be estimated according to the object weight that may store, considers that it presses down with upper lifting force poor approximately positive and negative, 20kg for example, i.e. and the minimum and maximum bearing capacity of nominal is poor is 40kg.As the household garden tool set, the storage cabinet of DIY instrument may be heavier, can select the nominal load total weight of container bottom (connect) of 80-100kg, select the intermediate value of 100kg as configuration, as long as just the ordinary people applies 20kg like this downforce or hoisting force can be easy to operate.Because scheme is not dragged container away from the needs of device, we just make a cabinet and are fixed on device base plate is whole, configure corresponding screen work and make storing articles; Top does not need to add a cover in addition yet, directly the structure at top has been designed just together with waterproof.If the article of some light weight points, as make the sinking net purchase case of receiving, or ground floor resident's sunk type storing (as the clothing foreign material etc.) cabinet, the counterweight of possible 20kg is just enough, with this first single Weighting system, bears that such application just is very easy to and flexible.
As adopt first and second counterweight (at this moment need to add lever arm of force do the independent operation that the second counterweight promotes use) or (with) scheme of the various combination of external force application system, the high a little point of cost, but the heavier application for carrier, do not need to spend too many strength when can make to promote, its degree easy to use can corresponding improve.
Although the utility model discloses as above with several preferred embodiments, the scope of not implementing in order to limit the utility model.Any those of ordinary skill in the art, within not breaking away from scope of the present utility model, when doing a little improvement, every equal improvement of doing according to the utility model, should be the utility model scope and contain.
