Description
Technical field
It is working that this utility model relates to tall and big concrete structure, the scaffold field that can go up and down.
Background technology
Scaffold (abbreviation climbing frame) with Motor Driven Elevating Calabash is China's original creation, and it makes major contribution in China high-story architecture construction field.At present popular mainly contain two kinds (seeing " building scaffolder " China Railway Press, 2009), a kind of be hang pull-type; Its early stage structure is seen Chinese patent ZL93222658, and there is run-off the straight problem in the lifting process in it, and improvement afterwards is along lifting rail scaffold; There is not tilt problem, the visible Chinese patent ZL93235702 of its old model, above-mentioned guide rail all can not go up and down voluntarily; Need the artificial unloading, carry and reinstall.
After nineteen ninety-five, various climbing frames are all equipped anti-drop device, the Chinese patent of many relevant anti-drop devices occurs, and some anti-drop device before and after Lifting and lowering for scaffold, also need be reinstalled and adjust it, has increased amount of operation labor.
Over nearly 20 years, the Chinese patent of relevant climbing frame has tens of, but aspect the mode of building, does not have too big variation at scaffolding structure and scaffold loading transfer, makes existing climbing frame have many common shortcomings.
At first be to rely on numerous diagonal members (rope), hang scaffold and move on the building that each diagonal member load size is decided by the length adjustment situation, if there is a diagonal member to lose efficacy, collapse in the part that scaffold just might take place.
Second shortcoming is complex structure, and parts are too many, and operation item is too many before and after going up and down, and some project is very heavy, for example; All diagonal members to be unclamped before and after going up and down, electric block be dismantled down, the cucurbit drop in beam, guide rail and anti-fall suspension rod etc. are transported to last layer; Even top layer, again from new installation adjustment, after the up-down, need be from new fixing all diagonal members and their length of adjustment; Operation item is a lot, and quite heavy, needs many personnel's Attended Operations, increases labour cost.
The 3rd shortcoming is the support body distortion; The scaffold rod member mainly bears pressure and bending moment, and support body is easy to generate distortion, and existing way is that " bottom load-bearing truss " is set in the scaffold lower edge; Be provided with at the position of accepting the electric block lifting force " vertical main frame "; Requiring them all is that bolt connects or welding, and this way makes the scaffold support body complicated, has increased the amount of labour when building and removing.
In a word, existing, no matter be that a kind of climbing frame; More or less all have complex structure, the component kind is many, will dismantle many kinds of component before and after going up and down; The carrying and reinstall adjustment, operation item is more, some operation item is quite heavy; The scene needs several workman's Attended Operations, and efficient is lower.
The utility model content
The utility model is to the shortcoming that existing climbing frame exists, and improves and innovates.At first change the scaffold loading transfer and give the mode of building, move the mode on the building to, change on the top of scaffold and be hooked on the mode on the building utilizing diagonal member to hang from the scaffold bottom at present; All diagonal members have been eliminated in this change, also do not have to go up and down the relevant operation of front and back to diagonal member, and the transfer route of power are clear and definite, have increased the safety in using.The most of rod member of scaffold does not bear pressure; The distortion of scaffold support body is little; Just can cancel at present for the rigidity that increases scaffold is provided with " vertical main frame " and " bottom load-bearing truss ", reduce the complexity of scaffold support body, reduce the amount of operation labor when building and removing.Hang over the electric block of up-down usefulness on the scaffold; Electric block is with scaffold one lifting; Having eliminated front and back needs dismounting, carries and reinstall the operation of adjustment cucurbit drop in beam and electric block, and avoids in these operating process, taking place easily the possibility of damage electric block.
Preventing that the guide rail that climbing frame tilts is arranged on the scaffold, to guide rail guiding is provided with the company's wall hanging seat that is installed on the building, prevent that climbing frame from tilting; Eliminated dismounting, carried and reinstalled the heavy operation of guide rail, simultaneously with the braking object of the guide rail on the scaffold as fall arrest; Be arranged on safety dropping prevent mechanism in company's wall hanging seat; Cancelled before and after some Lifting and lowering for scaffold, dismantle, carried and reinstalled the operation of adjustment safety dropping prevent mechanism.
According to the design's design, the climbing frame of design has only two kinds of parts, and a kind of is the scaffold support body that comprises the anti-dumping guide rail, and another kind is the company's wall hanging seat that comprises safety dropping prevent mechanism.Company's wall hanging seat of design has three kinds of functions: accept the scaffold load that guide rail passes over, and pass to building, guiding rail in lifting process prevents that climbing frame from tilting; Containing with the guide rail is the safety dropping prevent mechanism of braking object, prevents that climbing frame from falling downwards.Be designed to the function of safety dropping prevent mechanism can in three kinds of states, to carry out conversion; Promptly has anti-drop function; No anti-drop function and self-locking state can and connect wall hanging seat present position according to instructions for use, and the function of safety dropping prevent mechanism is carried out function selecting; Satisfy instructions for use, so-called self-locking state is meant that safety dropping prevent mechanism automatically tightens guide rail.
The design's climbing frame has only two kinds of parts; Not only simple in structure; The manufacturing workload is less, make easily and cost cheap, and the content of operation in the use only limits to installation and removal and connects the wall hanging seat; And the functional status of conversion safety dropping prevent mechanism as required, so be a kind of lifting false work easy and simple to handle.

The specific embodiment
Fig. 1 is the lateral view of the design's climbing frame; And the relative position of each several part before representative is climbed, the raw material of guide rail 4 are H shaped steel, are that main member scaffolds erecting with it; The outside wing plate of guide rail 4 is by three even wall hanging seat guiding controls; Three even the wall hanging seats connect wall hanging seat 1 on being respectively, in connect wall hanging seat 2 with under to connect 3, three wall hanging seats of wall hanging seat all be to be fixed on the building with through-wall bolt 12.
In position, scaffold upper middle cucurbit drop in beam 6 is set, the electric block 7 that promotes usefulness is hung on cucurbit drop in beam 6, is provided with in the lower end of guide rail 4 and turns to rope sheave 10, and it can rotate around its axle, and an end of cucurbit drop in beam 6 is connected on the guide rail 4.
According to the state on Fig. 1, the cucurbit suspension hook 9 of the electric block 7 of loweing catches on the mid point of boom hoist cable 11, and two strand steel wire ropes 11 of mid point both sides are walked around downwards and turned to rope sheave 10 to make progress again, are connected respectively to the both sides that connect wall hanging seat 1 to two terminations.In this case, if start electric block 7, shorten cucurbit chain 8, then scaffold relies on guide rail 4, serves as that guiding is upwards climbed with three company's wall hanging seats.The wing plate that Fig. 2 illustrates guide rail 4 is included in the gathering sill that connects in the wall hanging seat, can run-off the straight in the lifting process.Climb behind the story height, realize hanging scaffold on company's wall hanging seat 1 by the hook of the wedge shape on the guide rail 4 13.Connect at each cant beam 14 is set on the wall hanging seat; Fig. 3 a and Fig. 3 b illustrate the concrete structure and the duty of cant beam; Cant beam 14 can be around its axle 15 rotations, and when cant beam 14 was set level, it was crossed on the biside plate that connects the wall hanging seat; The wedge shape hook 13 that is welded on the guide rail 4 drops on the cant beam 14, and it is just given the scaffold loading transfer and connects the wall hanging seat.
In the process of climbing; When the hook of the wedge shape on the guide rail 4 13 is run into cant beam 14 from bottom to top; (Fig. 3 a) to utilize its inclined-plane to force cant beam 14 to turn clockwise; After the wedge shape hook was crossed cant beam 14, cant beam 14 relied on deadweight to return to horizontal level, and promptly cant beam 14 does not hinder the wedge shape hook from bottom to top through connecting the wall hanging seat; Then stop and the electric block that reverses; Scaffold is descended, fall on the cant beam 14, just accomplish the task of a story height of climbing frame rising until wedge shape hook 13; Promptly hung the wedge shape hook 13 on Zhong Lianqiang hanging seat 2 originally, hang now on Shang Lianqiang hanging seat 1.
Fig. 1 illustrates the main member that guide rail 4 is scaffold support bodys; On the web of guide rail 4, beat many circular holes by a determining deviation; Scaffold leans on all long transverse levers of wall one side all to pass these circular holes; And then be connected with hyphen bar or hound, therefore, the scaffold load that passes to long transverse lever is directly passed to guide rail 4.
Fig. 4 illustrates a kind of anti-fall structure that connects in the wall hanging seat, and even the right side wing plate of hang plate 16 in the wall hanging seat and guide rail 4 forms a wedge gap, and braking cylinder 17 is set in wedge gap; When the angle of inclination of hang plate 16 and braking cylinder 17 surfaces with hang plate 16 surfaces; And during the friction factor self-locking conditions satisfied on guide rail 4 wing plates surfaces,, just can block guide rail 4 if braking cylinder 17 falls into wedge gap; Stop guide rail 4 to continue to move downward, play anti-fall effect.Shift fork 18 can rotate around axle 19, and shift fork 18 can be stirred braking cylinder 17 and move up and down along hang plate, and braking cylinder 17 moves up and just leaves wedge gap, loses anti-drop function, moves down and just crashes into wedge gap, and anti-fall effect takes place.
If be connected shift fork 18 with wire rope 11, when cucurbit chain 8 or wire rope 11 lost efficacy, perhaps take place serious when asynchronous between the electric block; Make no longer support scaffolding load of this root wire rope; The wire rope deliquescing, because weight is eccentric, shift fork 18 is rotated counterclockwise (Fig. 4); Drive braking cylinder 17 and fall into barrier between wedge shape, anti-fall braking just takes place; If shift fork 18 with connect the wall hanging seat and be connected, and raise braking cylinder 17, shown in dotted line on Fig. 4; Among the braking cylinder is transported forever and can not be fallen between wedge shape, so safety dropping prevent mechanism loses anti-drop function, if shift fork 18 neither connects wire rope; Do not connect the wall hanging seat yet; Braking cylinder 17 always drops among the wedge gap, always blocks guide rail 4, and safety dropping prevent mechanism is in self-locking state.
Combine accompanying drawing now, describe the content of operation in rising and the decline process in detail, uphill process can begin from position shown in Figure 1.
1. the cant beam 14 in the company's of setting level wall hanging seat 1, in the safety dropping prevent mechanism that connects in the wall hanging seat 2 be transformed to anti-drop function.
2. the across-the-line starting electric block 7, shorten cucurbit chain 8, climbing scaffold, and guide rail 4 company's of receiving wall hanging seats lead, and link up with 13 jack-up and cross the cant beam 14 that connects wall hanging seat 1 up to the wedge shape on the guide rail, stop electric block.
3. counter-rotating electric block descends climbing frame, till the hook of the wedge shape on the guide rail 13 is fallen on the cant beam 14, stops electric block, just accomplishes therefrom to connect the wall hanging seat last wall hanging seat 1 that connects that climbs, and a story height has just risen.
4. if require scaffold to get into duty, all become self-locking state to the safety dropping prevent mechanism in the wall hanging seat, respectively connect the wall hanging seat and share scaffold load, increase the safety of use.
Describe now the content of operation of decline process, suppose that wedge shape hook 13 from the guide rail 4 is hung connecting wall base 1 and begin to descend, just from wall hanging seat 1 company's of dropping to wall hanging seat 2 even, content of operation is following:
1. connect the cant beam 14. on the wall hanging seat 2 in setting level
2. start electric block 7; Climbing frame is risen a little; Rise height and be as the criterion, lift cant beam 14 with the cant beam 14 that connects on can lifting on the wall hanging seat 1, at this moment three even the self-locking state of the safety dropping prevent mechanism in the wall hanging seat opened by moving upward of guide rail 4; In the safety dropping prevent mechanism that connects in the wall hanging seat 2 be transformed into anti-drop function, be transformed into no anti-drop function to the last wall hanging seat 1 that connects with the safety dropping prevent mechanism that connects wall base 3 down.
3. starting electric block 7 descends climbing frame, connect on the cant beam 14 of wall hanging seat 2 during the wedge shape hook 13 on guide rail 4 is fallen till, climbing frame is just accomplished the decline task of a story height.
4. as required, connect wall hanging seat 1 in the dismounting, go below being installed to supply to continue the use that descends, perhaps all be transformed to self-locking state to the safety dropping prevent mechanism in three wall hanging seats, make climbing frame be in user mode.
In sum, can find out, the design's climbing frame, simple in structure, number of parts is few, low cost of manufacture, in use, content of operation is seldom, and is and very easy.
