Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1 to 6, fig. 1 to 6 show an embodiment of the present invention, which mainly includes a wheel shaft, a chassis, a battery box and a driving unit, and mainly functions to complete the transportation of a workpiece. The wheel shaft consists of walking wheels and a vehicle shaft, and the walking wheels are arranged at two ends of the vehicle shaft and can support the motion of the whole mechanism.

The underframe is formed by welding two longitudinal beams and three cross beams, and one side of the underframe is used for supporting the weight of the battery, the workpiece and the conveying equipment. Referring to fig. 7 and 8, the base frame serves as a general chassis capable of detachably mounting a gripping device for transporting a workpiece, or a lifting device for use as a transplanting cart, and other devices. Because the device has certain weight, the other side of the underframe is provided with the battery box. The battery box is formed by welding plates, and the upper part of the battery box is open and used for storing batteries; the counterweight function can be realized by arranging the counterweight on the other side of the underframe, so that the underframe is prevented from easily overturning during working.

Referring to fig. 1 and 2, the two lateral sides of the underframe are rotatably connected with the two wheel shafts through bearings respectively, that is, the bottom of the longitudinal beam is connected with a bearing mounting seat, the bearing mounting seat is connected with the mounting seat through bolts, the bearing mounting seat and the mounting seat are matched with each other through semicircular components to clamp and fix the bearing, and the bearing and the axle are in interference fit. The driving unit consists of a motor and a speed reducer, the motor increases torque through the speed reducer to drive the axle to rotate, and finally the running wheels are driven to move along the track to provide power for the whole running mechanism.

Preferably, the edges of the wheel surfaces on the two sides of the walking wheel are respectively provided with a protruding annular wheel rim, the inner surfaces of the wheel rims can respectively cling to the outer walls on the two sides of the track, the track is clamped under the condition of low speed and heavy load, and difficult derailment can be ensured.

Preferably, referring to FIG. 4, the axle is integrally machined and keyed to the running wheels. In order to realize radial fixation, the end part of the axle is provided with a cover plate, the inner side of the cover plate is in a step shape and is correspondingly matched with the traveling wheels, and axial fixation is realized.
