Description
Technical field:
The utility model relates to the light rail motor tractor hoisting device, relate in particular to a kind of can be fast with the quick jack-up machine of folding of the light rail motor tractor of light rail motor tractor jack-up.
Background technology:
At present, jacking system is few on the market, and jacking system commonly used is a jack, and jack is the simplest jacking device of a kind of lifting highly little (less than 1m).It has two kinds of mechanical type and fluid pressure types.The mechanical type jack has rack-and-pinion and spiral two kinds again, because top weight is little, the operation effort generally only is used for flight-line maintenance work, and is now uncommon.Fluid pressure type jack structure compactness, stable working has self-locking action, so use extensively.
Hydraulic jack is divided into general and special-purpose two classes.
The dedicated hydraulic jack is special-purpose tensioner, when making prestressed concrete member, deformed bar is applied tension force.The dedicated hydraulic jack mostly is double-acting type.Commonly used has feedthrough and bores two kinds of anchor formulas.
General jack is mainly used in departments such as factories and miness, communications and transportation and pushes up work such as weight, support as Mechanical Help and other.Its structure is lightly firm, flexibility and reliability, and a people is portability and operation.Jack is to lift part as equipment with rigid top, the light little weight-lifting equipment of jacking weight in little stroke by top bracket or bottom claw.Jack is divided into by principle of work:
(1) lifting screw: adopt screw rod or lift the jack of part by the jacking sleeve that screw rod promotes as rigid top.
(2) rank-and-pinion jack: adopt tooth bar to lift the jack of part as rigid top.
(3) oil jack: adopt plunger or hydraulic actuating cylinder to lift the jack of part as rigid top.
The principle of work of jack
Mechanical jack is different with the hydraulic jack principle, hydrostatic drive based on the most basic principle be exactly pascal's principle, in other words, liquid pressure everywhere is consistent, like this, in the system of balance, applied pressure is smaller above the smaller piston, and applied pressure is also bigger on the big piston, can keep the static of liquid like this.So by the transmission of liquid, can obtain the different pressure on the different ends, so just can reach the purpose of a conversion.We common to hydraulic jack be exactly to have utilized this principle to reach the transmission of power.The lifting screw theory of machines, back and forth to pull handle, pusher dog promptly promotes the revolution of ratchet gap, and bevel pinion drives large bevel gear, makes the rotation of weight lifting screw rod, thereby makes jacking sleeve obtain to hoist or descend, and reaches the function of lifting pulling force.But it is simple and easy to be not so good as hydraulic jack.
Generally speaking, the shortcoming of existing jack: 1, complex structure; 2, be difficult for processing and manufacturing; 3, cost costliness, 4, lifting object height degree is limited.5, lifting velocity is slow.
The utility model content:
Shortcoming at above-mentioned existing jacking system (jack), the purpose of this utility model provides a kind of new-type jacking system, promptly simple and reasonable, safe in utilization, quick, utilize the lever principle can be with the quick jack-up machine of the light rail motor tractor folding of light rail motor tractor jack-up.
The technical solution of the utility model realizes with following method:
The quick jack-up machine of light rail motor tractor folding, comprise base 3, be movably arranged on the support beam 2 on the base, be movably arranged on the handle bar 7 on the support beam 2, wherein, described handle bar 7 one ends are provided with support hook 1, also be provided with hitch 6 on the handle bar 7, hitch 6 is provided with suspension hook bar 5, and suspension hook bar 5 is provided with suspension hook 9, and base 3 is provided with a suspension hook hanging ring 4 that joins with suspension hook 9.
Described support hook 1 can be the concave shape hook.
Described support beam 2 is provided with the support beam control apparatus 12 of adjustable support beam 2 height.
3 of described support beam 2 and bases also are provided with a drag wire 11.
Described suspension hook bar 5 is provided with at least two position-limited troughs 8.
Described suspension hook 9 and 5 sockets of suspension hook bar.
Described suspension hook 9 is provided with spacing card 10.
The good effect of technical solutions of the utility model is:
The quick jack-up machine of this light rail motor tractor folding, utilization lever principle, simple structure, reasonable; Use laborsaving, save time, only need press down handle bar, just can reach the jack-up effect, the body height also can be regulated according to object height, but the higher object of jack-up; Easily processing and manufacturing, no complicated machinery and hydraulic oil passage device, but just processing and manufacturing of general engineering staff; Because devices such as no machinery and hydraulic pressure only need raw materials such as bolt and nut and section bar, so cost reduces greatly; Since adopted movable connection method between each parts of the quick jack-up machine of this light rail motor tractor folding, collapsible, carry so be convenient to place.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the technical solution of the utility model is further described:
As seen from Figure 1, the quick jack-up machine of this light rail motor tractor folding, comprise a base 3, the hinged support beam 2 that is equipped with on the base, support beam 2 is provided with the support beam control apparatus 12 of adjustable support beam 2 height, the hinged one handle bar 7 that is equipped with of the other end of support beam 2, wherein, handle bar 7 one ends are provided with the support hook 1 of a concave shape, also be connected with a hitch 6 on the handle bar 7, hitch 6 can be one and hangs circle, is connected with a suspension hook bar 5 on the hitch 6, is socketed with a suspension hook 9 on the suspension hook bar 5.
It can also be seen that by Fig. 1 support beam 2 is hinged near 1/3rd places on the handle bar 7 of support hook 1 one sides.
It can also be seen that by Fig. 1 also be provided with a suspension hook hanging ring 4 on the base 3, suspension hook hanging ring 4 can have different in size a plurality of.
Be it can also be seen that by Fig. 1 suspension hook bar 5 is provided with position-limited trough 8, suspension hook 9 is provided with a spacing card 10.Spacing card 10 on the suspension hook 9 is stuck in the position-limited trough 8 on the suspension hook bar 5.
