A dual-purpose four-wheel bicycle

Abstract

The invention provides a dual-purpose four-wheeled bicycle, belongs to the technical field of transportation means, and effectively solves the problem of high transportation cost on railway short-distance overhauling operation. Two groups of pedals of a driving mechanism are connected with a chain wheel axle through a chain wheel chain; a chain wheel is arranged on the chain wheel axle; the chain wheel axle is connected with a shell of a differential mechanism through the chain; a small chain wheel is arranged on a motor output axle; the motor output axle is connected with the shell of the differential mechanism through the chain; the chain wheel axle and the motor output axle are meshed with left and right rear half axles through planetary gear. A lifting pressure rod is arranged on the rear portion of a frame; the two ends of the a rotating shaft of the lifting pressure rod are fixed to a lifting pressure rod mounting base of the frame through shaft sleeves; the left end of a push rod is hinged to the lower end of the lifting pressure rod, and the lower end of the push rod is fixed to a lifting wheel axle. Guide rod sliding sleeves are arranged in the middle of the frame; guide rods are fixed to guide rod sliding sleeve mounting bases of the frame through the guide rod sliding sleeves; the guide rods are in clearance fit with the guide rod sliding sleeves, and locking devices are arranged between the guide rods and the guide rod sliding sleeves; the guide rods on both sides are connected through a synchronous connecting rod. The dual-purpose four-wheeled bicycle is mainly applied to railway short-distance overhauling operation.

Description

Technical field [0001] The invention belongs to the technical field of vehicles, and particularly relates to the general structure design of a dual-purpose four-wheel bicycle. Background technique [0002] The existing vehicles used by the maintenance workers on the railway are large and medium-sized engineering vehicles with guide wheels as the blueprint of freight cars, which account for the majority. After receiving the maintenance task, first discuss which maintenance tools are needed, and then assign tasks, and then the workers first install the necessary maintenance equipment on the maintenance vehicle. Due to the large number of passing trains, in order not to affect the traffic, the inspection vehicles usually have to be dispatched about an hour in advance, waiting for the arrival of the operating "skylight point" outside the station. Until the station dispatching room gave the order, then enter the station and drive to the work site for maintenance. After the overhaul ...
