Abstract
The utility model discloses a special hoist for rail hoisting and belongs to the field of railway pavement and rail maintenance technology. The special hoist for rail hoisting comprises a hoist body, a hoisting chain, a lifting appliance, a walking driving shaft, a four-wheeled trolley and a hand crank. The hoist body comprises a lifting driving shaft; the four-wheeled trolley comprises walking wheels and driven wheels, wherein the walking wheels are installed on the walking driving shaft; the hand crank can be detachably installed on the lifting driving shaft for lifting and lowering the lifting appliance or can be detachably installed on the walking driving shaft for driving the walking wheels. When the hand crank is installed on the lifting driving shaft, the hand crank rotates to drive the lifting driving shaft to rotate and thus the lifting and lowering of the lifting appliance and the hoisting of steel rails are achieved; and when the hand crank is installed on the walking driving shaft, the walking of the special hoist and the transfer of the steel rails can be achieved, the working efficiency of hoisting and transfer is high, less manual work is needed, and the construction progress of railway pavement and rail maintenance is fast. The hand crank can be detachably installed on the lifting driving shaft and the walking driving shaft in an alternate manner, thereby serving dual purposes.
Description
[technical field]
The utility model relates to a kind of rail and lifts special cucurbit, belongs to railway laying, rail maintenance technology field.
[background technology]
At present, each railway is laid, rail maintenance department still adopts a dead lift modes to carry out on-the-spot railway laying, rail upkeep operation more, exist manual operation efficiency low, the deficiency that artificial requirement is large, constructor's physical demands is large, can not meet the short demand of maintenance period after construction speed and railway speed increase.Adopt the operation of Lever Blocks lifting rail, because Lever Blocks operation exists idle stroke, slinging work efficiency is not high, and field work arranges suspension centre inconvenience; And exist the lifting altitude problem that has certain requirements with Chain block, and need to have high-order hook suspension centre for Chain block hanging install could, but railway laying, rail safeguard that construction operation is characterized in only needing rail to hang ground.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of rail to lift special cucurbit for the above-mentioned state of the art.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A kind of rail lifts special cucurbit, it is trolley type cucurbit, comprise cucurbit body, hoisting chain, suspender, propel driving shaft and lorry, described cucurbit body has the driving shaft of hoisting, lorry has road wheel and driven pulley, and described road wheel is installed on propel driving shaft, and its improvement is: also comprise wind, described wind or removable being installed on the driving shaft that hoists in order to elevating sling, or removable being installed on propel driving shaft in order to ground-engaging wheel.
On above-mentioned cucurbit body, be also provided with the brake screw with handle, brake screw is for road wheel braking or remove road wheel braking.
When rail be suspended from the ground and move in place after, need to be placed into rail is safe and reliable, exactly on target station time, drive brake screw rotation by handle, to clamp road wheel, the utility model can be still on special hoisting bar; When rail after being suspended from the ground need to move, can brake off, allow the utility model flatly walking on special hoisting bar end face, be convenient to rail accurately in place.
The utility model compared with prior art tool has the following advantages:
Adopt after technique scheme, hoist on driving shaft wind is installed, along with rotating, wind drives the drive shaft turns that hoists, realize the lifting action of suspender, carry out smoothly the lifting operation of rail, lifting operating efficiency is high, and wind is installed on propel driving shaft, realize walking action of the present utility model, carry out smoothly the movement operation of rail.Movement operating efficiency is high, and artificial consumption is few, and operating personnel's physical demands is little, and railway is laid, rail safeguards that construction speed is fast.Because wind replaces removable being installed on the driving shaft that hoists, propel driving shaft, while being loaded on the driving shaft that hoists, for lifting the utility model, while being loaded on propel driving shaft, for mobile the utility model, thereby realize a thing dual-purpose.
[accompanying drawing explanation]
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
[specific embodiment]
Referring to shown in Fig. 1, Fig. 2, is preferred embodiment of the present utility model.
A kind of rail lifts special cucurbit, it is dolly and cucurbit fabricated structure, comprise cucurbit body 1, hoisting chain 5, suspender 3, propel driving shaft 40 and lorry, described cucurbit body 1 has the driving shaft of hoisting 10, lorry has road wheel 4 and driven pulley 8, described road wheel 4 is installed on propel driving shaft 40, its improvement is: also comprise wind 2, described wind 2 or removable being installed on the driving shaft 10 that hoists in order to elevating sling 3, or removable being installed on propel driving shaft 40 in order to ground-engaging wheel 4.
On cucurbit body 1, be also provided with the brake screw 7 with handle 6, brake screw 7 is for applying the braking constraint that brake force realizes braking or removes road wheel 4 to road wheel 4.
When concrete use, the utility model is placed in special racks (not shown), special racks is place vertical with rail, this special racks is made up of two legs and two parallel girders, article two, the each end of parallel girder is fixed on two legs, article two, the end face of parallel girder lifts special cucurbit for placing two cover rails, road wheel 4, driven pulley 8 can be along the smooth rolling of parallel girder end face, every cover rail lifts wherein one end of the suspender clasp joint rail of special cucurbit, positive and negative rotation is loaded on the wind 2 hoisting on driving shaft 10, realize the lift work of rail, when wind 2 dismounting on propel driving shaft 40 with positive and negative rotary handle crank 2, carry out the movement operation of rail, brake screw 7 rotates until while clamping road wheel 4, 4 of the road wheels that rail lifts special cucurbit are still on special hoisting bar, this rail lifts special cucurbit and has met railway laying completely, rail is safeguarded the real work requirement of construction operation.
Claims (2)
1. a rail lifts special cucurbit, it is trolley type cucurbit, comprise cucurbit body, hoisting chain, suspender, propel driving shaft and lorry, described cucurbit body has the driving shaft of hoisting, lorry has road wheel and driven pulley, and described road wheel is installed on propel driving shaft, it is characterized in that: also comprise wind, described wind or removable being installed on the driving shaft that hoists in order to elevating sling, or removable being installed on propel driving shaft in order to ground-engaging wheel.
