Description

Technical Field

[0001] This utility model relates to the field of mining cart technology, specifically an automatic mining cart and a tipping device. Background Technology

[0002] With the continuous development of the mining industry, mechanization and automation are inevitable trends. However, as an old mine, due to the constraints of the initial site selection and terrain, achieving mechanization requires the modification of on-site civil engineering and equipment, which involves a large amount of work. Moreover, the modification process requires production to be stopped, affecting production. As an old mine, it has always been in a passive state in terms of technological transformation. The ore transportation process is cumbersome and has a low safety factor. Every time a carload of ore is lifted, from underground to the mine entrance, it is all done manually. The process involves many steps, is time-consuming, labor-intensive, and has safety risks. In order to improve transportation efficiency, a combined device such as a mine entrance pusher, a silo puller, and a tipper was designed.

[0003] Traditional mine shaft pushing and tipping technologies have shortcomings. On the one hand, they mostly rely on manual or semi-mechanized operations, requiring a large number of operators, resulting in high labor intensity. Moreover, the pushing and tipping efficiency is low, leading to long cage downtime and severely impacting ore extraction efficiency. On the other hand, the installation of traditional equipment often requires modification of the foundation facilities, necessitating production shutdowns during installation, increasing construction difficulty and costs, and affecting the stability of the original mine shaft structure due to foundation alterations. Furthermore, traditional technologies struggle to automate the operation of pushing loaded cars from empty ones, exhibiting low equipment linkage and intelligence levels, failing to meet the demands of modern mine high-efficiency production. These shortcomings significantly restrict the overall efficiency and economic benefits of mining. Therefore, we propose an automatic pushing and tipping combined device for mines.

[0049] Working principle: Motor 2 drives gearbox 1 via synchronous belt. Gearbox 1 transmits power to common chassis 3, causing guide wheels 4 mounted at the bottom of common chassis 3 to move along rail 17, thus driving the entire device to move on rail 17. At the same time, roller 5 mounted at the front of common chassis 3 rotates under the drive of motor 2 and gearbox 1. The steel wire rope 6 wound around roller 5 and guide wheels 4 moves accordingly. The push-pull head 9 connected to one end of the steel wire rope 6 is forked and inserted into the front of the mine car. The device is pulled by the steel wire rope 6. The device enables pulling and pushing actions on the trolley.

The tension bracket 8 is fixed to the top of the common chassis 3, with one end connected to the tension spring 7 and the other end pressed against the wire rope 6. It can adjust the tension of the wire rope 6 in real time, ensuring it maintains appropriate tension during traction and preventing insufficient or excessive tension from affecting the trolley's movement. When the device moves the mine car... When the mine car reaches the tipper support 14, the tipper support 14, which is fixed to the ground and located at the center of the back of the track 17, comes into play. It includes a car stabilizing stop 12 and a tipper stop 13. The car stabilizing stop 12 is located at the bottom of the tipper stop 13. The two work together to tip the mine car over, completing operations such as unloading. In addition, the curved track 15 on the left side of the common chassis 3 works with the cage brake crank 16. When the cage lifts the loaded car into place, the cage brake crank 16 moves along the curved track 15, triggering the opening of the inner brake of the cage, realizing the linkage between the cage and the device, and ensuring the mine car is in operation. Accurate docking and operation during transportation: In the entire device, all components such as motor 2, gearbox 1, and roller 5 are integrated into a common chassis 3, forming a modular structure. It moves along the track 17 laid on the ground via guide wheels 4. No foundation changes are required during installation, making it suitable for the renovation of old mines. Through the coordinated linkage of various structures, the automatic pushing and tipping functions are realized, improving the automation level of mine transportation and unloading, reducing labor costs, and increasing work efficiency. At the same time, the cooperation of various structures ensures the stability and reliability of operation.
