Description

Technical Field

[0001] This utility model relates to the field of mine cage technology, specifically a mine cage door fixing device. Background Technology

[0002] Cages are hoisting devices used in mines in China to transport equipment and personnel. The safety of cage use is directly related to the safety of transported equipment and personnel. For example, in a lifting cage door disclosed in Chinese patent literature (application number: CN201920680151.4), the lifting of the cage door is mainly achieved by steel wire and pulley assembly. The steel wire rope will undergo elastic deformation under load, resulting in lag in the transmission process. The steel wire rope has low torsional and bending stiffness, which may cause vibration or resonance, affecting the stability of movement. Long-term friction between the steel wire and the pulley / guide device will cause surface wear and even wire breakage, requiring regular replacement, resulting in high maintenance costs. In addition, the setting of counterweight plate increases the mass of the cage itself and reduces the load-bearing capacity of the cage.

[0003] Therefore, we propose a mine cage door fixing device. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-3This utility model provides a technical solution: a mine cage door fixing device, including a cage 1 and a cage door 2, a cavity 3, the cavity 3 being disposed on the front and rear sides of the cage 1, a positioning hole 31 being provided on the inner wall of the cavity 3, two sets of mounting blocks 4 being disposed on the bottom left side of the cage 1, a first guide groove 10 being disposed on the inner wall of the cavity 3, a second guide groove 11 being disposed on the inner wall of the cavity 3, the second guide groove 11 being located below the first guide groove 10, a first positioning shaft 6 being disposed in the cavity 3, the end of the first positioning shaft 6 being connected to the first guide groove 10. The guide rod 15 is connected to the inner wall of the guide groove 10. The fixing block 7 is fixedly connected to the first positioning shaft 6. The support rod 8 is fixedly installed at the bottom of the fixing block 7. The second positioning shaft 9 is fixedly connected to the bottom of the support rod 8. The end of the second positioning shaft 9 is connected to the inner wall of the second guide groove 11. The push rod 12 is located on the right side of the fixing block 7. The threaded sleeve 14 is fixedly connected to the right end of the push rod 12. The guide plate 13 is fixedly installed on the inner wall of the cavity 3. The threaded sleeve 14 passes through the guide plate 13. The threaded sleeve 14 is movably connected to the guide plate 13. The threaded rod 15 is connected to the threaded sleeve 14. The motor bracket 16 is fixedly installed inside the cavity 3, and the geared motor 17 is fixedly installed on the top of the motor bracket 16. The drive shaft of the geared motor 17 is fixedly connected to the left end of the threaded rod 15. When the cage door 2 is closed, the geared motor 17 is started, which drives the threaded rod 15 to rotate. The threaded rod 15 cooperates with the threaded sleeve 14. During the rotation of the threaded rod 15, the threaded sleeve 14 moves to the right. The threaded sleeve 14 drives the fixed block 7 to move to the right through the push rod 12. The fixed block 7 pulls the pull rod 8 through the first positioning shaft 6. The first positioning shaft 6 slides to the right within the first guide groove 10, simultaneously pulling up the cage door 2 via the pull rod 5. The cage door 2 gradually rises and closes. During the closing process of the cage door 2, the support rod 8 and the second positioning shaft 9 guide and stabilize the movement of the fixing block 7, opening the cage door 2. The movement of the fixing block 7 causes the pull rod 5 to pull up the cage door 2. The cage door 2 does not lag during the closing process, and the cage door 2 operates stably during the closing process, is not easy to loosen, and improves the overall safety of the cage door 2 during the closing process.

[0032] Reference embodiment: A mounting hole 18 is provided in the middle of the fixing block 7, and a spring 19 is provided in the mounting hole 18. A positioning rod 20 is provided at the top of the spring 19, and a through groove 21 is provided in the lower half of the positioning rod 20. A mounting groove 22 is provided on the right side of the mounting hole 18, and a through hole 23 is provided at the right end of the mounting groove 22. A push block 24 is provided in the mounting groove 22. The bottom of the through groove 21 is set as an inclined surface, and the lower left part of the push block 24 is set as an inclined surface that cooperates with the bottom of the through groove 21. During the closing process of the cage door 2, when the first positioning shaft 6 moves to the rightmost end of the first guide groove 10, the positioning rod 20 moves to the positioning hole 31, the spring 19 pushes the positioning rod 20, and the positioning rod 20 is stuck in the positioning hole 31, fixing the fixing block 7 so that the fixing block 7 cannot move. The cage door 2 To improve the safety of cage 1 during the lifting process, cage door 2 is opened when the processing cannot be completed. The reduction motor 17 reverses, and the threaded rod 15 rotates, causing the threaded sleeve 14 to move to the right. The threaded sleeve 14 first pushes the push block 24 to the left through the push rod 12. The inclined surface on the push block 24 cooperates with the inclined surface in the through groove 21. The push block 24 pushes the positioning rod 20 downward, and the positioning rod 20 disengages from the positioning hole 31, releasing the fixation of the fixing block 7. After the push block 24 pushes the positioning rod 20 out of the positioning hole 31, the left end of the threaded sleeve 14 contacts the right side of the fixing block 7, pushing the fixing block 7 to the left, opening cage door 2. After opening, cage door 2 is located between cage 1 and the ground, serving as a passage for transportation equipment and personnel.

[0033] Reference embodiment: The push rod 12 passes through the through hole 23 and is fixedly connected to the push block 24. The threaded sleeve 14 first pushes the push block 24 to move through the push rod 12. The push block 24 pushes the positioning rod 20 to move downward, disengage from the positioning hole 31, and loosens the fixation on the fixing block 7.

[0034] Reference embodiment: The first positioning shaft 6 passes through the right end of the pull rod 5, and the first positioning shaft 6 is movably connected to the pull rod 5. The left end of the pull rod 5 is connected to the cage door 2 by a pin. During the opening or closing of the cage door 2, both ends of the pull rod 5 rotate on the first positioning shaft 6 and the pin. The right end of the cage door 2 is connected to the mounting block 4 by a pin. The cage door 2 is opened or closed by rotating the pin.
