[0002] The elevator pit inspection and repositioning device comprises several key components. The most important is the elevator pit inspection and repositioning circuit control device, which, through control circuit connections, resets each component to its normal operating state. Other components include a traction machine brake device for adjusting the car's position to ensure car stability; and a buffer reset mechanism that allows the buffer to quickly return to its initial state after maintenance, ready to respond to any potential car bottoming-out incidents.

[0003] The working principle of the elevator pit inspection and reset circuit control device is to control relevant components through a circuit system. It utilizes internal electrical components to disconnect the elevator's operating circuit during maintenance. After maintenance is completed, the circuit connection is restored by operating the reset button, returning all components to their normal operating state. Its primary application is in elevator pit maintenance work, ensuring the safety of maintenance personnel and guaranteeing that the elevator can accurately and reliably resume normal operation after maintenance.

[0004] In the "use first, technology later" approach, some electrical control devices are typically mounted on the mounting plate with screws. When it is necessary to inspect or replace the electrical control devices again, the screws are difficult to remove, especially after long-term use when the screws may rust or strip, which increases the difficulty of disassembly, prolongs the maintenance time, and increases the vacuum period of elevator use, thus affecting its operation. To address this issue, an elevator pit inspection and repositioning device is proposed. Utility Model Content

The elevator reset control device 21 is fixedly connected to the inner wall of the mounting box 15. The elevator reset control device 21 is the core part of the entire device and is used to control the reset of the elevator. A filter screen 22 is fixedly connected to the outer wall of the box cover 9. The filter screen 22 is used to filter dust in the air and prevent dust from entering the interior of the mounting box 15 and affecting the operation of the electrical equipment.

[0036] A mounting plate 12 is detachably connected to the bottom of the base plate 1. An elastic spring 7 is fixedly connected to the inner wall of the mounting plate 12. The elastic spring 7 provides elastic force to the retaining ball 8, allowing the retaining ball 8 to cooperate with the clamp 4. One end of the elastic spring 7 is fixedly connected to the retaining ball 8, which can move under the action of the elastic spring 7. It cooperates with the clamp 4 to realize the detachment of the mounting box 15. The outer wall of the retaining ball 8 contacts the outer wall of the clamp 4. The fixing and disassembly of the mounting box 15 are realized through the contact and interaction between the two. One end of the return spring 6 is fixedly connected to the inner wall of the base plate 1, so that the return spring 6 can provide a return force to the connecting column 16. A sealing ring 20 is fixedly connected to the bottom of the box cover 9. The sealing ring 20 can cooperate with the sealing groove 19 to play a sealing role and prevent foreign objects from entering the interior of the mounting box 15. A sealing groove 19 is opened on the top of the mounting box 15. The sealing groove 19 is used to install the sealing ring 20 and together with the sealing ring 20, they play a sealing role. The outer wall of the sealing ring 20 is installed on the inner wall of the sealing groove 19. The two fit tightly to ensure the sealing effect.

[0037] Reference Figures 1 to 3 The ventilation assembly includes a ventilation fan 17, which, when activated, drives airflow to circulate air inside the mounting box 15. The outer wall of the ventilation fan 17 is fixedly connected to the inner wall of the mounting box 15, allowing the ventilation fan 17 to be stably installed inside the mounting box 15 for operation. A dust filter 10 is fixedly connected to the top of the base plate 1, which filters dust in the air and prevents dust from entering the mounting box 15 and hindering the operation of electrical equipment. A filter 22 is fixedly connected to the bottom of the mounting box 15 to further filter the air and ensure the cleanliness of the air entering the mounting box 15. A ventilation hole 14 is provided at the bottom of the mounting box 15, through which air flows out to achieve air circulation.

[0038] The outer wall of the mounting box 15 is rotatably connected to a cover 9, which can be opened and closed to facilitate operation inside the mounting box 15. A glass window 13 is fixedly connected to the outer wall of the cover 9, which allows observation of the interior of the mounting box 15 without opening the cover 9 to check the status of the internal equipment.

Multiple cable routing grooves 18 are provided on the inner wall of the base plate 1 to assist in the wiring inside the mounting box 15, making the wiring neater and more orderly.

[0039] Working principle: When the control device in the elevator pit inspection and reset device needs to be inspected or replaced, press the button 3. The downward movement of the button 3, due to the restriction of the rotating rod 2, will drive the transmission rod 5 to rotate, thereby causing the connecting column 16 to drive the clamp 4 to move upward. At this time, the upward movement of the clamp 4 will apply a pushing force to both sides of the clamping balls 8. Under the action of the elastic spring 7, the clamping balls 8 will move to both sides. Then, the base plate 1 can be removed to complete the disassembly of the mounting box 15, so as to inspect or replace the internal elevator reset control device 21. This greatly facilitates the maintenance personnel in the elevator inspection, improves the efficiency of the inspection work, and enables the elevator to be put into use more quickly after inspection.

[0040] During daily use of the device, airflow is needed to address moisture or heat dissipation issues on the inner wall of the mounting box 15. At this time, the ventilation fan 17 is activated, driving airflow. The dust filter 10 filters dust from the air to prevent it from entering the mounting box 15 and interfering with the operation of the internal electrical equipment. Then, the air flows out through the ventilation hole 14 at the bottom, thus maintaining constant airflow inside the mounting box 15. The wiring trough 18 assists in wiring inside the mounting box 15, and the cable outlet 11 facilitates the wires to pass through and connect to other circuit devices. The glass window 13 allows observation of the interior of the mounting box 15. The sealing ring 20 and the sealing groove 19 work together to seal the interior of the mounting box 15, preventing foreign objects from entering.
