Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a self-generating explosion-proof device for cage rollers. Background Technology

[0002] Currently, the cages used for hoisting in main and auxiliary shafts of coal mines lose a significant amount of energy during operation, resulting in waste. Storing this energy and enabling its secondary utilization would save energy, reduce costs, and improve the economic efficiency of coal mines. This aligns with the national sustainable development strategy and the policy of creating a resource-saving society, and has practical value. Existing cage-generating devices lack flexibility, typically using a direct mounting shaft on the rollers. This method makes it difficult to adjust the generator's power output according to the cage's running speed, potentially leading to excessive power output, damage to the generator, and reduced operational safety. Furthermore, the friction wheels of existing cage-generating devices are prone to slippage, resulting in poor operational stability. Therefore, we propose a cage roller self-generating explosion-proof device to address these issues. Utility Model Content

[0025] Please see Figure 1-6 This utility model provides a technical solution: it includes a base plate 100, and a mounting mechanism is provided on the top of the base plate 100. The mounting mechanism includes a mounting base 210, which is fixed to the top of the base plate 100 by bolts. A mounting stud 220 is provided on the inner wall of the mounting base 210. A mounting bracket 230 is rotatably connected to the outer side of the mounting stud 220. A roller mechanism is provided on the inner wall of the mounting bracket 230.

[0026] The power generation mechanism includes a support frame 510, a support plate 520, a connecting pin 521, and a mounting sleeve 530. A permanent magnet generator 540 is fixed to one side of the mounting sleeve 530. A drive shaft 541 is provided at the output end of the permanent magnet generator 540. A friction wheel 550 is fixed to the outside of the drive shaft 541. A connecting block 570 is fixed to the outside of the permanent magnet generator 540. A clamping mechanism is provided on the outside of the power generation mechanism. By setting up the mounting mechanism, the roller mechanism, and the power generation mechanism, before the power generation mechanism is installed, a friction wheel 550 of appropriate diameter is selected according to the running speed of the cage, and the support frame 510 is installed on the mounting sleeve. On one side of the bracket 230, the friction wheel 550 is pressed onto the roller 340. The rotation of the roller 340 drives the friction wheel 550 to rotate, which in turn drives the drive shaft 541 to rotate, thereby generating electricity through the permanent magnet generator 540. This allows for easy adjustment of the power output of the permanent magnet generator 540 according to the running speed of the cage, avoiding situations where the power output is too high or too low, thus improving the safety of the power generation operation. At the same time, it increases the flexibility of the power generation device. Furthermore, the friction wheel 550 is pressed down by a clamping mechanism to prevent slippage and ensure the stability of the power generation operation.

[0027] Specifically, the support mechanism includes a rotating base A410, which is fixed to the top of the mounting bracket 230 by bolts. A connecting seat A420 is rotatably connected to the inner wall of the rotating base A410. A damper 430 is fixed to the bottom of the connecting seat A420. A connecting seat B440 is fixed to the bottom of the damper 430. A rotating base B450 is rotatably connected to the outer side of the connecting seat B440. The rotating base B450 is fixedly connected to the base plate 100. By providing the support mechanism, the damper 430 can buffer and support the vibration of the roller 340, ensuring the stability of the cage operation.

[0028] Specifically, a reinforcing rib plate 511 is fixed to the bottom of the support frame 510; by setting the reinforcing rib plate 511 to securely support the support frame 510, the stability of the power generation operation is ensured.

[0029] Specifically, an explosion-proof generator controller 560 is fixed on the top of the permanent magnet generator 540; the operation of the permanent magnet generator 540 is controlled by the explosion-proof generator controller 560.

A groove 620 is formed on the inner wall of the guide plate 610, and a mounting bolt 630 is slidably connected to the inner wall of the groove 620. A fastening bolt 640 is provided on the outer side of the mounting bolt 630. The mounting bolt 630 is rotatably connected to the connecting block 570. By providing the clamping mechanism, the connecting block 570 is installed through the cooperation of the mounting bolt 630 and the fastening bolt 640. The mounting bolt 630 can slide freely on the groove 620, guiding and adjusting the position of the permanent magnet generator 540, thereby adjusting the position of the friction wheel 550, facilitating adjustment of the friction wheel 550 according to the size and position of the roller 340.

[0031] Specifically, a support slide 650 is fixed to the side of the support frame 510 near the guide plate 610. A mounting column 660 is fixed to the inner wall of the support slide 650. A spring 661 is provided on the outer side of the mounting column 660. A pressure ring 670 is slidably connected to the outer side of the mounting column 660 near the spring 661. A drive slide plate 680 is provided at the bottom of the pressure ring 670. The drive slide plate 680 is fixedly connected to the connecting block 570. By providing a pressing mechanism, during power generation, the spring 661 presses the pressure ring 670 onto the drive slide plate 680. The drive slide plate 680 slides on the mounting column 660. The drive slide plate 680 applies a pressing force to the permanent magnet generator 540 through the connecting block 570, thereby driving the friction wheel 550 to press against the roller 340, preventing the friction wheel 550 from slipping and ensuring the stability of the power generation operation.

[0032] Working Principle: During use, the permanent magnet generator 540 is controlled by an explosion-proof generator controller 560. Before installation, a friction wheel 550 of appropriate diameter is selected according to the cage's running speed. The support frame 510 is installed on one side of the mounting bracket 230, and the friction wheel 550 is pressed onto the roller 340. The rotation of the roller 340 drives the friction wheel 550 to rotate, which in turn drives the drive shaft 541 to rotate, thus generating electricity through the permanent magnet generator 540. This allows for easy adjustment of the generator's power output according to the cage's running speed. When the roller 340 rolls on the track, it rotates on the rotating base A410 via a damper 430 and a connecting seat A420. The damper 430 also rotates on the rotating base B450 via a connecting seat B440. The roller 340 transmits vibration to the mounting bracket 230 via the mounting shaft 330. On the frame 230, the mounting bracket 230 rotates on the mounting base 210. The damper 430 can buffer and support the vibration of the roller 340. The connecting block 570 is installed by the cooperation of the mounting bolt 630 and the fastening bolt 640. The mounting bolt 630 can slide freely on the slide groove 620. The position of the permanent magnet generator 540 is guided and adjusted by the slide groove 620, and then the position of the friction wheel 550 is adjusted. It is convenient to adjust the friction wheel 550 according to the size and position of the roller 340. During the power generation operation, the pressure ring 670 is pressed onto the drive slide plate 680 by the spring 661. The drive slide plate 680 slides on the mounting slide column 660. The drive slide plate 680 applies the clamping force to the permanent magnet generator 540 through the connecting block 570, thereby driving the friction wheel 550 to press tightly onto the roller 340, so as to prevent the friction wheel 550 from slipping.
