Description

Technical Field

[0001] This utility model relates to the field of control box equipment technology, specifically a wireless control box for a mine hoist cage. Background Technology

[0002] Mining hoist cages are a crucial component of underground mine hoisting systems, primarily used for transporting personnel, materials, and ore. The cage is typically suspended from hoisting wire ropes and moves up and down via the hoist's drive system. In modern mines, to improve the safety and efficiency of the hoisting system, wireless control boxes are usually installed on the cages. These boxes can collect real-time operating status data of the cage, such as position, speed, and load, and transmit this data to the ground control center via wireless communication technology, enabling remote monitoring and control. Furthermore, the wireless control box can issue alarm signals in emergencies to ensure the safety of personnel and equipment. Therefore, the installation of wireless control boxes is of great significance for improving the intelligence and safety of mining hoist cages.

[0003] In existing technologies, wireless control boxes installed on mine hoist cages are typically fixed to the cage's mounting plate using multiple bolts. When maintaining the wireless control box, maintenance personnel must remove each bolt individually to remove it from the cage, and then retighten them one by one during installation. This method is not only time-consuming and labor-intensive, but also extremely inconvenient in the confined space of a mine. Especially in complex and space-constrained mine environments, frequent bolt removal and installation significantly reduces maintenance efficiency and may even increase the workload and safety hazards for maintenance personnel. Therefore, this invention proposes a wireless control box for a mine hoist cage to solve the above problems. Utility Model Content

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a wireless control box for a mine hoist cage, comprising: a wireless control box body 1, which is prior art, containing a wireless communication module, a sensor module, and a controller module, with a power supply module installed at its bottom. The wireless communication module enables wireless communication between the ground control station and the cage. The controller module receives control commands from the ground control station and controls the operation of the cage. The sensor module collects the operating status information of the cage and sends the information to the cage controller module. The power supply module provides power to the wireless communication module, the cage controller module, and the sensor module. The ground control station sends control commands to the cage controller module through the wireless communication module. The cage controller module controls the operation of the cage according to received instructions. Simultaneously, the sensor module collects the cage's operating status information in real time and transmits this information to the ground control station via a wireless communication module. The ground control station processes and displays the information, enabling remote monitoring of the cage. A mounting plate 2 is located on the rear of the wireless control box 1. This mounting plate 2 facilitates the subsequent fixing of the wireless control box 1, and its four corners can be secured to the cage using large bolts. A detachable protective cover 3 is attached to the front of the wireless control box 1. This detachable protective cover 3 protects the wireless control box 1 and facilitates subsequent maintenance and use. Limit sleeves 4 are fixedly connected to the left and right side walls of the box body 1. A limit component is provided on one side of the limit sleeve 4. The limit component can quickly limit or release the wireless control box body 1, thereby facilitating its disassembly. The limit component includes a limit frame 5. A limit post 6 is sleeved in the limit frame 5 in a direction parallel to the mounting plate 2. A connecting post 7 is sleeved in the limit frame 5 in a direction perpendicular to the mounting plate 2. The limit post 6 and the connecting post 7 are vertically distributed. One end of the limit post 6 is slidably inserted into the limit sleeve 4. One side of the outer ring of the limit post 6 is slidably connected to the limit frame 5. The other side of the outer ring of the limit post 6 is slidably connected to one end of the connecting post 7. An adjustment component is provided at the other end of the connecting post 7. The adjustment component facilitates the movement of the connecting post 7. The connecting post 7 is slidably sleeved on the limit frame. Within 5, the limiting frame 5 limits the limiting post 6 and the connecting post 7. The limiting frame 5 is fixedly connected to the mounting plate 2. The limiting frame 5 and the mounting plate 2 are fixed together by hexagonal socket head cap screws. The adjustment component includes a support sleeve 8. The support sleeve 8 is internally threaded with an adjustment rod 9. One end of the adjustment rod 9 is fixedly connected to one end of the connecting shaft 10. The other end of the connecting shaft 10 is fixedly sleeved on the inner ring surface of the limiting bearing 11. The outer ring surface of the limiting bearing 11 is embedded in the end of the connecting post 7 away from the limiting post 6. The limiting bearing 11 adopts an inner rotation and outer ring fixed installation method, so that the connecting shaft 10 can rotate within the limiting bearing 11. The support sleeve 8 is fixedly connected to the limiting frame 5. The support sleeve 8 is slidably connected to the connecting post 7, so that the connecting post 7 is limited by the support sleeve 8.

[0024] The mounting plate 2 has a slot 12 on the side that abuts against the wireless control box body 1. The slot 12 is slidably inserted into one side of the sealing ring 13, and the other side of the sealing ring 13 is fixedly connected to the protective cover 3. By covering the outside of the wireless control box body 1 with the protective cover 3, the sealing ring 13 fixedly connected to one side of the protective cover 3 will be inserted into the slot 12 on the mounting plate 2, thereby improving the sealing between the protective cover 3 and the mounting plate 2, thus preventing external dust from entering the wireless control box body 1 and affecting the service life of its internal components. A dustproof mesh plate 14 is fixedly installed at the bottom of the protective cover 3. This design prevents dust from entering the protective cover 3 while ensuring ventilation inside and outside the protective cover 3, which is beneficial for heat dissipation of the wireless control box body 1. Limiting holes 15 are opened on the left and right side walls of the protective cover 3. The limiting holes 15 are arranged in a linear array. The limiting holes 15 are slidably inserted into one end of the locking pin 16. The other end of the locking pin 16 is fixedly connected to the lifting bracket 17. The lifting bracket 17 is fixedly connected to one end of the spring 18. The other end of the spring 18 is fixedly connected to the limiting plate 19. One side of the limiting plate 19 is fixedly connected to the mounting plate 2. The locking pin 16 is slidably inserted into the limiting plate 19, thereby limiting the locking pin 16.

[0025] Two limiting strips 20 are fixedly connected to one side of the outer ring surface of the limiting post 6. The two limiting strips 20 are arranged in an oblique L-shape. A first sliding groove 21 is opened on the other side of the outer ring surface of the limiting post 6, and a second sliding groove 22 is opened on one side of the outer ring surface of the connecting post 7. The first sliding groove 21 and the second sliding groove 22 are slidably connected to the limiting pin 23 fixedly connected to the limiting frame 5, thereby improving the stability of the limiting post 6 and the connecting post 7 during movement. A protrusion 24 is slidably connected between the two limiting strips 20. The protrusion 24 is fixedly connected to the end of the connecting post 7 away from the limiting bearing 11. The end of the adjusting rod 9 away from the connecting shaft 10 is fixedly connected to one end of the short rod 25. The other end of the short rod 25 is fixedly connected to the handwheel 26, thereby facilitating the rotation of the adjusting rod 9 by rotating the handwheel 26.

[0026] In actual use, when it is necessary to install the wireless control box body 1, first fix it to the side wall of the cage using the large bolts at the four corners of the mounting plate 2, then fix the limit bracket 5 to the mounting plate 2 using hexagonal socket head cap screws. Next, abut the back of the wireless control box body 1 against the mounting plate 2, making the limit sleeve 4 and the limit post 6 coaxial. At this time, by turning the handwheel 26, the adjusting rod 9 is driven to rotate under the connecting action of the short rod 25. Since the adjusting rod 9 is threadedly connected to the inner wall of the support sleeve 8, the adjusting rod 9 will move inward into the support sleeve 8. At the same time, the adjusting rod 9 will drive the connecting shaft 10 to rotate, and the connecting shaft 10 and the limit post 6 will rotate together. The bearings 11 are installed with the inner ring rotating and the outer ring fixed, which drives the limit bearing 11 to move closer to the mounting plate 2. The limit bearing 11 is fixedly connected to the connecting column 7, so that the connecting column 7 also moves closer to the mounting plate 2 under the cooperation of the second slide groove 22 and the limit pin 23. The connecting column 7 slides between two obliquely arranged L-shaped limit bars 20 through the protrusion 24 fixedly connected to it, thereby driving the limit column 6 to move. Under the limiting sliding cooperation of the first slide groove 21 and the limit pin 23, the limit column 6 moves closer to the limit sleeve 4 until one end of the limit column 6 is inserted into the limit sleeve 4. The limiting post 6 abuts against the side wall of the wireless control box body 1 within the sleeve 4, thus completing the limiting installation of the wireless control box body 1. Then, by pulling the lifting bracket 17 outwards, the lifting bracket 17 causes the locking pin 16 to slide out of the limiting plate 19. Next, the protective cover 3 is placed over the outside of the wireless control box body 1. At this time, the sealing ring 13 fixedly connected to one side of the protective cover 3 will be inserted into the slot 12 on the mounting plate 2, thereby improving the sealing between the protective cover 3 and the mounting plate 2, thus preventing external dust from entering the wireless control box body 1 and affecting the service life of its internal components. During this process, the spring 18 is stretched and then released. By opening the lifting bracket 17, the locking pin 16 can be slidably inserted into the limiting hole 15, thereby limiting and fixing the protective cover 3. The protective cover 3 protects the wireless control box body 1, thus preventing debris from hitting the wireless control box body 1 and affecting its safety. When the wireless control box body 1 needs to be disassembled for maintenance, the lifting bracket 17 needs to be pulled in the opposite direction to contact the locking pin 16 to limit the limiting hole 15, so that the protective cover 3 can be removed. Then, the handwheel 26 is turned in the opposite direction to indirectly slide the connecting column 7 away from the mounting plate 2, so that the limiting column 6 can slide out of the limiting sleeve 4, and then the wireless control box body 1 can be disassembled.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
