Continuous hydraulic traction device

Abstract

The invention provides A continuous hydraulic traction device which comprises a guide bracket and a cylinder support bracket,one end of that guide bracket is connected with two steel cables, the otherend of the steel cable is fixed on the steel cable tray, the two steel cable discs are fixed on the two rails, A support frame of that oil cylinder is provide with an oil cylinder, one end of the oilcylinder is fixed on the oil cylinder support frame, the other end is connected a guide wheel, A steel wire rope fix end is fixed on that top of the oil cylinder support frame, A suspension wheel support seat is fix on that support frame of the oil cylinder, a suspension wheel is fixed on the support frame of the suspension wheel, and one end of a steel rope is fix on the fixed end of the steel rope and extends toward the guide bracket, and the steel rope extends in the reverse direction aft bypassing the guide wheel and passes through the suspension wheel and is connected in a traction chain. The steel rope is fixed on the fixed end of the steel rope and extends in the direction of the guide bracket. The travel distance of the oil cylinder of the invention is half of the travel distanceof the train, and the traction frequency can be shortened by half, and even the derailment train can be retracted at one time, thereby greatly reducing the time required for traction.

Description

technical field [0001] The invention belongs to the technical field of train traction equipment, in particular to a continuous hydraulic traction device. Background technique [0002] As the most important and economical mode of transportation in the world today, railway transportation has an irreplaceable advantage in the world freight and passenger transportation market. After the existing train is derailed, a rerailer needs to be used for rerailing. Most of the rerailers are of the inner and outer type. The rerailer is placed in front of the train wheels, and the tractor is used to let the train climb the rails and enter To achieve rerailing on the correct rail, the existing tractors basically adopt the way of oil cylinder traction, the stroke of the oil cylinder is limited, and if the derailed train needs to be rerailed, it needs to be towed for a certain distance, which requires multiple times of traction to reassemble the train. Rail, the number of times of traction i...

The rerailer is placed in front of the train wheels, and the tractor is used to let the train climb the rails and enter To achieve rerailing on the correct rail, the existing tractors basically adopt the way of oil cylinder traction, the stroke of the oil cylinder is limited, and if the derailed train needs to be rerailed, it needs to be towed for a certain distance, which requires multiple times of traction to reassemble the train. Rail, many times of pulling, wasting time
