A hydraulic tool cart

Abstract

The invention relates to a hydraulic tool car. The hydraulic tool car comprises a body frame, a lifting plate, a bearing plate, a hydraulic cylinder and a pedal, wherein a plurality of walking slide blocks are arranged at the bottom end of the body frame, the lifting plate is connected with the body frame through a lifting mechanism, the bearing plate is connected with the lifting plate in a sliding mode, the bearing plate is divided into a plurality of sliding areas through limiting plates, universal balls are arranged in each sliding area, locking blocks are arranged on the edges of the sliding areas, locking holes are formed in the locking blocks, one end of the hydraulic cylinder is hinged to the body frame, the other end of the hydraulic cylinder is hinged to the lifting plate, and the pedal is arranged on the body frame and used for driving the hydraulic cylinder. The hydraulic tool car of the scheme serves as a standby device of an automatic battery replacement device and is installed on one side of a slide rail, the adjustment on the X axis is achieved through the operation of the slide rail and the slide block, and the adjustment on the Y axis is achieved through rising and falling of the hydraulic cylinder; the telescopic adjustment on the Z axis is achieved when the bearing plate transversely slides, and therefore the manual battery replacement work is completed when the automatic battery replacement device fails.

Description

Technical field [0001] The invention relates to the field of hydraulic tools, in particular to a hydraulic tool cart. Background technique [0002] The current energy supply for electric commercial vehicles is mainly divided into two types: charging and swapping. [0003] The charging mode does not require disassembly of the battery and can be charged directly. However, the charging process is too long and will delay a lot of time, so it is impossible to complete the energy supply of electric commercial vehicles in a short time. [0004] The battery swap mode adopts fully automatic battery swap equipment for replacement. The battery boxes of electric commercial vehicles are distributed in the battery frame on both sides of the vehicle. When the battery is replaced, the X and Y axis positioning are required. After the position is corrected, the Z axis is extended and retracted. The locking mechanism on the battery box is unlocked, and the battery is pushed and pulled. The box compl...

AI Technical Summary

Problems solved by technology

The torque of the motor mostly increases with the increase of the speed. Correspondingly, in the starting stage of the motor, the required torque is the largest, but the output torque of the motor is the smallest. However, most of the batteries currently used are lead-acid batteries. Larger, so it often causes the bad situation of motor stall;

[0008] (3) The battery box needs to be driven by the carrying mechanism to realize lifting, but the carrying mechanism is only equipped with rollers without any positioning device

During the battery replacement process, the battery box often slides around on the rollers, thus increasing the battery replacement time and reducing the power replacement efficiency
