Abstract
The invention discloses a liftable supporting leg device which comprises an outer supporting leg, a liftable inner supporting leg is sleeved in the outer supporting leg, an idler wheel is arranged at the lower end of the inner supporting leg, and a lifting oil cylinder is arranged in the inner supporting leg. When the liftable support leg device is used, a left end part and a right end part are sleeved on a railway locomotive. When the end part of the locomotive is hoisted by a hoist, the load at the locomotive end is increased, the inner supporting leg extends out, the idler wheel is pressed on a steel rail, and the hoisting load on the locomotive is transferred to the steel rail through the inner supporting leg and the idler wheel so as to avoid the end part of the locomotive body being deformed due to over-high load; and when the locomotive travels at a low speed or in a hoisting way, the liftable supporting leg device does not need to be retracted, and the idler wheel can roll along the steel rail, therefore, when the locomotive is used for hoisting, not only the strength and the rigidity of the end part of the locomotive can be guaranteed, but also the locomotive can be maintained to travel at a low speed, therefore, the operation efficiency is greatly improved, and the work intensity of operators is lightened.
Description
Technical field
The present invention relates to railway track maintenance of equipment---the be engaged in equipment that uses on the railcar of worker.
Background technology
The lifting landing 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 lifting landing 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, and operating personnel are 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 lifting landing leg device of operating efficiency.
Technical scheme of the present invention is: be with liftable interior supporting leg in the outer supporting leg, roller is equipped with in interior supporting leg lower end.
Supporting leg was in the present invention was liftable: in the interior supporting leg hoist cylinder is installed, the upper bracket of hoist cylinder is loaded on outer supporting leg, and the undersetting of hoist cylinder is connected with roller.Interior supporting leg drives the roller lifting by the hoist cylinder lifting, props up on rail, thereby guarantee the stability of car load and the effect of rigidity when the crane lift heavy.
Supporting leg was in the present invention was liftable: the roller of interior supporting leg lower end is connected with hoist cylinder through rolling wheel support.
Described outer supporting leg upper end has mounting flange, outer supporting leg to be fixed on through mounting flange on the underframe of rolling stock, and the installation site of outer supporting leg on the underframe of rolling stock is corresponding with railway track.
Described outer supporting leg has two, is with liftable interior supporting leg in each outer supporting leg, 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 interior supporting legs is connected with synchronous crossbeam through rolling wheel support.
Described outer supporting leg has two, be with liftable interior supporting leg in each outer supporting leg, two outer supporting legs upper ends are loaded on a fixed support, and hoist cylinder is arranged on the fixed support, the hoist cylinder lower end is loaded on synchronous crossbeam, and the roller of two interior 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 in use, encapsulation is in the end of rolling stock.When on the vehicle end during loop wheel machine lift heavy, car end load strengthens, interior supporting leg stretches out, roller is pressed on the rail, lift heavy load on the car passes to rail by supporting leg 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, the lifting landing leg device need not packed up, and lifting landing leg device roller can roll along rail.
The invention has the beneficial effects as follows: the walking of can on rail, rolling of the roller of lifting landing 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 operating personnel's working strength.
