Coupled with the breakthroughs in power battery technology and its control systems, it provides a basis for the electrification of trackless equipment in mines. The attention of each mining unit to pure electric trackless equipment has gradually increased, and trackless equipment manufacturers have also actively turned to the research and development of pure electric and intelligent trackless equipment. At the same time, with the continuous breakthroughs in related technologies of mine pure electric vehicles and communication technologies, the trend of pure electrification and remote control driverless of underground trackless equipment has become more obvious. "Electrification, automation, and intelligence" will be the inevitable trend of the development of underground mining and transportation equipment in mines, and safe, efficient, and clean mines will become an important development direction for the future mining industry. And the batteries that power new energy underground trackless equipment are restricted by production technology requirements and are all high-power, large-capacity, heavy-weight, and large-size. The underground operation environment is high-temperature, humid, with noise and air pollution, and the trackless equipment operation is accompanied by bumps, knocks, and impact loads, so the limit fixation of the battery pack becomes even more important. Summary of the Invention

[0003] The present invention provides a battery quick-change automatic locking mechanism for new energy trackless equipment in mines to solve the problems in the above background that the battery replacement and locking of new energy underground trackless equipment are time-consuming, laborious, and have low safety.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A battery quick-change automatic locking mechanism for new energy trackless equipment in mines includes a vehicle frame. A sliding seat is connected to the vehicle frame, and a sliding cover is detachably connected to the sliding seat. A rotating shaft is provided between the sliding seat and the sliding cover. Steel sleeves are provided at both the upper and lower parts of the rotating shaft. The steel sleeves are connected with locking plates. The steel sleeves and the rotating shaft are connected by pins. A connecting plate is fixedly provided at the lower end of the rotating shaft. The connecting plate is connected with a locking cylinder. The upper hinge seat of the locking cylinder is arranged at the upper part of the locking cylinder. The locking cylinder is also connected with a lower hinge seat, and both the upper hinge seat and the lower hinge seat are fixedly arranged on the vehicle frame.

[0005] Further, a plurality of lifting cylinders are detachably provided on the vehicle frame, and the piston ends of the lifting cylinders are all connected with lifting support plates.

[0006] Furthermore, reinforcing plates are fixedly arranged between the steel sleeve and the lock plate.

[0007] The present invention has the following beneficial effects: For the automatic locking mechanism for quick battery replacement of a mine new energy trackless equipment provided by the present invention, the vehicle frame is connected to a sliding seat, the lower end of a rotating shaft is connected to a locking oil cylinder, and the upper and lower hinge seats of the locking oil cylinder are fixed on the vehicle frame. When replacing the battery pack, the lifting oil cylinder drives the lifting support plate to act, lifting the battery pack to a certain height. Then, the locking oil cylinder drives the lock plate to move downward, clamping the pin shaft into the notch of the lock plate to complete the locking of the battery pack. When the battery pack descends, the locking oil cylinder acts, the lock plate moves upward to separate the pin shaft from the notch of the lock plate, and then the lifting oil cylinder drives the lifting support plate to act to lower the battery pack. This automatic locking mechanism is applied to underground or surface trackless equipment. The mechanism is compactly arranged, occupies less space, is convenient for installation, maintenance and repair, effectively meets the production requirements of the complex environment in the mine, and greatly solves the problems that the battery replacement and locking of the current mine new energy trackless equipment are time-consuming, laborious and have low safety.

[0008] The present invention can be applied to underground or surface trackless equipment, has a compact structure, can automatically complete the locking of the battery pack, limit and lock the battery pack, has a reasonable structural design and is convenient for installation, inspection and maintenance.
