A transport vehicle with variable lateral wheelbase

Abstract

The invention discloses a transport vehicle with variable transverse wheelbase, which comprises a tractor, a vehicle frame is arranged at the rear of the tractor, the vehicle frame includes a left vehicle frame and a right vehicle frame, and the left vehicle frame and the right vehicle frame Sliding boards are arranged between the frames, the left frame is provided with baffles, and the baffles are provided with movable plates, the left frame and the right frame chassis are provided with worm gears and wheels, and the two sides of the wheels are provided with the second A support rod, a first hydraulic cylinder is set in the middle of the slide plate, a transmission rod is set on the first hydraulic cylinder, a second hydraulic cylinder is set on the front end of the slide plate, and a first sleeve is set horizontally on the second hydraulic cylinder , the second sleeve, the second sliding rod, the second sleeve and the second sliding rod are provided with a worm, and the tractor is provided with a hydraulic drive device. The beneficial effect of the present invention is that: when transporting goods, the axial distance between the wheels can be increased, the transport volume of goods can be increased, and the safety of goods transport can be increased.

Description

technical field [0001] The invention mainly relates to the field of cargo transport, in particular to a transport vehicle with variable lateral wheelbase. Background technique [0002] At present, in the process of cargo transportation, the cargo is often too long or too wide to be conveniently transported. Only a part of the cargo is placed on the outside of the frame, which greatly reduces the safety of the transport vehicle, and sometimes there will be lateral swings on the frame. There is a certain amount of space left after placing several goods of a certain width, resulting in a vacancy of the frame, which reduces the efficiency of material transportation. If the goods are placed partly beyond the frame, the goods may fall from the frame, increasing the load transport hazards. So people began to increase the width of the frame. After the width of the frame increases, the traffic will be hindered when the vehicle is transported by air, which will easily cause traffic j...

[0002] At present, in the process of cargo transportation, the cargo is often too long or too wide to be conveniently transported. Only a part of the cargo is placed on the outside of the frame, which greatly reduces the safety of the transport vehicle, and sometimes there will be lateral swings on the frame. A certain amount of space is left after placing several goods of a certain width, resulting in a vacancy of the frame and reducing the efficiency of material transportation. If the goods are placed beyond the frame, the goods may fall from the frame, increasing the load transport hazards

So people began to increase the width of the frame. After the width of the frame increases, the traffic will be hindered when the vehicle is transported by air, which will easily cause traffic jams. Side drift problem
