Abstract
The invention relates to a swinging leg device. A hinge shaft is mounted at the upper end of a leg, and a roller wheel is mounted at the lower end of the leg, wherein the leg can rotate around the hinge shaft. A lifting cylinder is mounted on the leg, the upper end of the lifting cylinder is mounted on a chassis of a railway locomotive car, and the lower end of the lifting cylinder is connected with the leg. In use, a left swinging leg device and a right swinging leg device are sleeved at the end part of the railway locomotive car. When a hoist at the end part of the car is used for hoisting, the load on the car is increased, the cylinders extend out, the legs are swung downwards around the hinge shafts to press the roller wheels on steel rails, and the hoisted load on the car is transmitted to the steel rails through the cylinders and the roller wheels, thus preventing the end part of the car from bearing overhigh load and being deformed; and when the car travels at a low speed or travels during the hoisting operation, the swinging leg devices are not required to be retracted, and the roller wheels can roll along the steel rails. Thus, the invention can ensure the strength and the rigidity of the end part of the car and can keep the low-speed travelling of the car in the hoisting operation process of the car, thereby greatly improving the operation efficiency, and reducing the working strength of operators.
Description
Technical field
The present invention relates to railway track maintenance of equipment---the be engaged in equipment that uses on the rail vehicle of worker.
Background technology
The oscillating support leg device is a kind of equipment of the loop wheel machine that carries on permanent way maintenance car transmitted load when being used to lift equipment such as rail, track switch.When on the car during loop wheel machine lift heavy, by supporting leg, give rail with the lift heavy loading transfer, bear excessive load and be out of shape to avoid the car body end.Existing support leg device is the vertical oscillation support leg device, is positioned at the rail both sides, and a load dish is installed in the supporting leg bottom.When supporting leg was fallen, vehicle can not traveling, has only supporting leg is packed up, and vehicle could traveling.Like this, every operation is once wanted earlier supporting leg to be packed up, and the another location of walking again falls the supporting leg operation again.Because of it needs continuous operate lifting, it is low to pretend industry efficient, easily makes operating personal tired out.
Summary of the invention
The above-mentioned deficiency that the objective of the invention is to overcome prior art provides a kind of when guaranteeing locomotive underframe rigidity, can greatly improve the oscillating support leg device of operating efficiency.
Technical scheme of the present invention is: the hinge that supporting leg is rotated around it is equipped with in the supporting leg upper end, and roller is equipped with in the lower end.
On the said supporting leg of the present invention hoist cylinder is installed, the upper end of hoist cylinder is loaded on the underframe of rolling stock, and the lower end of hoist cylinder is connected with supporting leg.
On the said supporting leg of the present invention hoist cylinder is installed, the upper end of hoist cylinder is loaded on the underframe of rolling stock, and the roller of supporting leg lower end is connected with the hoist cylinder lower end through rolling wheel support.
Said supporting leg is fixed on through hinged-support on the underframe of rolling stock, and the installation site of supporting leg on the underframe of rolling stock is corresponding with railway track.
Described supporting leg has two, and the hoist cylinder upper end is loaded on the underframe of rolling stock, and the hoist cylinder lower end is loaded on synchronous crossbeam, and the roller of two supporting legs is connected with synchronous crossbeam through rolling wheel support.
For guaranteeing that roller does not break away from rail when crossing curve, the outer inside and outside both sides that the outside that can adopt mode of widening roller widths or the mode that adopts roller to increase wheel rim promptly to have wheel rim, roller in the inboard of roller has wheel rim or roller all have wheel rim, to guarantee that the present invention can not break away from rail in use.
The present invention props up on rail by the lifting of hoist cylinder lifting drive roller, thereby guarantees the stability and the rigidity of car load when the hoisting crane lift heavy.In use, two ends that are set in rolling stock about.When on the vehicle end during loop wheel machine lift heavy, car end load strengthens, supporting leg around hinge to lower swing, roller is pressed on the rail, lift heavy load on the car passes to rail by oil cylinder and roller, and bear excessive load and be out of shape to avoid the car body end, and when traveling of vehicle low speed or lift heavy traveling, supporting leg need not packed up, and roller of the present invention can roll along rail.
The invention has the beneficial effects as follows: the walking of can on rail, rolling of the roller of oscillating support leg device, during the vehicle lift heavy, the strength and stiffness of vehicle end can be guaranteed, the traveling of vehicle low speed can be kept again, improve operating efficiency greatly, alleviated the working strength of operating personal.
