Description

Technical Field

[0001] The present invention relates to the technical field of elevator door lock inspection, and specifically relates to an elevator door lock inspection and detection device and a detection method thereof. Background Technique

[0002] With the acceleration of the urbanization process, high-rise buildings are emerging continuously. As an important tool for vertical transportation, elevators have been widely used in residential communities, commercial buildings, office buildings and other places. The extensive use of a large number of elevators has made the safety issues of elevators increasingly concerned. As a key component to ensure the safe operation of elevators, the performance of elevator door locks is directly related to the lives of passengers. Therefore, it is necessary to conduct strict inspections on them to ensure that they always maintain a reliable working state during frequent use.

[0003] Most traditional elevator door locks only detect the meshing depth of the elevator door lock and the locked state of the elevator door after long-term use, and do not conduct static tensile tests on elevator door locks used for a long time. They cannot effectively guarantee the safety of elevator door locks and timely discover potential problems. Therefore, in order to solve the above problems, the existence of an elevator door lock inspection and detection device and a detection method thereof is crucial. Summary of the Invention

The outer diameter size of the docking block matches the inner diameter size of the docking groove. An opening is provided through the middle of the docking block, and the inner diameter size of the opening matches the outer diameter size of the lever.

[0014] An inspection and detection method for an elevator door lock includes the following operation steps:

[0015] S1. Ensure that the elevator is in a stopped state, and set obvious warning signs at the elevator hall door to prevent unauthorized personnel from accidentally taking the elevator. At the same time, prepare the required tools.

[0016] S2. Disassemble the elevator door lock and disconnect the connection between the elevator door lock and the elevator control system.

[0017] S3. Open the second box door, pour the cleaning liquid into the cleaning box, then place the elevator door lock on the placement rack in the cleaning box, and check whether the elevator door lock is submerged by the cleaning liquid.

[0020] S6. The telescopic rod extends and retracts downward, and the staff can remove the elevator door lock on the pneumatic clamping plate.

[0021] S7. Install the elevator door lock back to its original position and restore the electrical connection. Then clean the site, put away the tools, remove the warning signs, and resume the normal operation of the elevator.

[0022] (III) Beneficial effects

[0023] The present invention provides an elevator door lock inspection and detection device and its detection method, which have the following beneficial effects:

[0024] (1). By setting up a cleaning box, ultrasonic transducers, an ultrasonic generator, electric heating tubes, a placement rack, and a bearing block, before conducting a static tension test on the elevator door lock, place the elevator door lock on the upper surface of the placement rack in the cleaning box, and at the same time the elevator door lock is immersed in the cleaning liquid. Due to the complex structure of the elevator door lock, there are many fine gaps, holes, and uneven surfaces, and these parts are prone to accumulating dirt such as dust, oil stains, and metal chips. Ultrasonic cleaning uses high-frequency vibration to generate countless tiny bubbles in the cleaning liquid. When these bubbles burst on the surface of the door lock, they will generate a strong impact force, which can penetrate into various fine gaps to completely remove the dirt. At the same time, ultrasonic cleaning is a non-contact cleaning method and will not cause physical damage to the components of the elevator door lock. After cleaning, dry the elevator door lock with the electric heating tubes, effectively avoiding the chemical reaction between the residual moisture on the surface of the elevator door lock components and the oxygen in the air, resulting in the rusting of metal components. In addition, there are some electrical components and circuits in the elevator door lock, and drying with the electric heating tubes can ensure that the electrical components and circuits are in a dry state, improving the electrical safety and reliability of the door lock. At the same time, drying can eliminate the influence of moisture on the components, ensure that the performance indicators of the door lock meet the requirements, enable it to work properly, ensure the safe operation of the elevator, and improve work efficiency.

[0025] (2) By providing a pneumatic clamping plate, a tensile force sensor, a column, a mounting panel, a cylinder, a telescopic rod, a first connecting rod, and a second connecting rod, clamping the elevator door lock with the pneumatic clamping plate can effectively avoid the problem of bolt rebound caused by excessive tensile force during traditional bolt fixing. In addition, the pneumatic clamping plate is driven by air pressure, and the clamping force is generated by the pressure of the gas. This force can be evenly distributed on the surface of the elevator door lock, improving the clamping and fixing effect and also enhancing the efficiency of clamping or disassembling the elevator door lock. Moreover, arc-shaped holes are provided on both the left and right sides of the mounting panel. The inner diameter size of the arc-shaped holes matches the outer diameter size of the column, which can effectively ensure the stability of the position of the mounting panel during up and down movement during tensile force detection and avoid deviation during movement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1-6 shown, the present invention provides a technical solution: an elevator door lock inspection and detection device, including a bottom plate 1. At both ends of the front and back of the bottom plate 1, there are provided toggle levers 2. On the top of the bottom plate 1, there is a docking groove 3. On one side of the top of the bottom plate 1, there is a processing box 4. On the top of the processing box 4, there is a control console 5. On the front of the processing box 4, there is a first box door 6. Below the first box door 6, there is a second box door 7. On the other side of the top of the bottom plate 1, there are two columns 8. On the top of the columns 8, there is a top plate 9. On the top of the top plate 9, there is a cylinder 10. Between the two columns 8 and on the top of the bottom plate 1, there is a pneumatic clamping plate 11. The outer wall of the column 8 is slidably connected with a mounting panel 12. On the top of the mounting panel 12, there is a mounting plate 13. On the top of the mounting plate 13, there is fixedly connected a connecting cylinder 14. Inside the connecting cylinder 14, there is a first connecting rod 15.

[0035] Furthermore, pneumatic clamping plates 11 are provided at the top of the bottom plate 1 and the bottom of the mounting panel 12. The model of the pneumatic clamping plate 11 is TH-94. The pneumatic clamping plate 11 is driven by air pressure, and uses the pressure of the gas to generate a clamping force. This force can be evenly distributed on the surface of the elevator door lock, improving the clamping and fixing effect, and also improving the efficiency when clamping or disassembling the elevator door lock.

[0036] Furthermore, the processing box 4 includes a drying chamber 16 and a cleaning chamber 20. On both sides of the inner wall of the drying chamber 16, there are provided electric heating tubes 17. At the bottom of the drying chamber 16, there is a water collecting tank 18. In the middle of the inner wall of the water collecting tank 18, there is a placement rack 19. Inside the cleaning chamber 20, there is a cleaning box 21. Inside the inner wall of the cleaning box 21, there is a bearing block 26. Inside the cleaning box 21, there is a ultrasonic transducer 27. On the outer wall of the cleaning box 21, there is a ultrasonic generator 28. On the outer wall of the cleaning box 21, there is a drain pipe 29. Ultrasonic cleaning uses high-frequency vibration to generate countless tiny bubbles in the cleaning liquid. When these bubbles burst on the surface of the door lock, they will generate a strong impact force, which can penetrate into various fine gaps and thoroughly remove dirt. At the same time, ultrasonic cleaning is a non-contact cleaning method, which will not cause physical damage to the components of the elevator door lock. After cleaning, the elevator door lock is dried through the electric heating tubes 17, effectively avoiding the chemical reaction between the residual moisture on the surface of the elevator door lock components and the oxygen in the air, resulting in the rusting of metal components. In addition, there are some electrical components and circuits in the elevator door lock, which are dried through the electric heating tubes 17, which can ensure that the electrical components and circuits are in a dry state, improving the electrical safety and reliability of the door lock. At the same time, drying can eliminate the influence of moisture on the components, ensure that the performance indicators of the door lock meet the requirements, enable it to work normally, ensure the safe operation of the elevator, and improve the work efficiency.

[0037] Furthermore, load-bearing blocks 26 are fixedly connected to the inner walls of both the water collecting tank 18 and the cleaning box 21. Placing racks 19 are arranged in both the water collecting tank 18 and the cleaning box 21, and the placing racks 19 are located on the upper surfaces of the load-bearing blocks 26. A water delivery pipe is arranged at the bottom of the water collecting tank 18, and the water outlet end of the water delivery pipe is located directly above the cleaning box 21, so as to return the cleaning liquid dripping from the surface of the elevator door lock to the cleaning box 21, avoiding waste and improving the drying efficiency at the same time.

[0038] Furthermore, a limiting ring 24 is fixedly connected to the lower part of the outer wall of the lever 2. A spring 25 is sleeved on the outer wall of the lever 2 and the spring 25 is located on one side of the limiting ring 24. The spring 25 can drive the lever 2 to reset, maintaining the stability of the outer cover 22, facilitating subsequent staff to store and move the device, and avoiding external damage.

[0039] Furthermore, a movable telescopic rod 30 is arranged in the air cylinder 10. One end of the first connecting rod 15 located outside the connecting cylinder 14 is provided with a tension sensor 31. One end of the telescopic rod 30 located outside the air cylinder 10 is provided with a second connecting rod 32. The tension sensor 31 is connected to the control console 5 through a cable. The tension sensor 31 can accurately sense and measure the magnitude of the applied tension, so as to judge whether the tension that the elevator door lock can withstand in the static state meets the safety standards, ensuring the safety of the elevator door lock during use and facilitating the staff to timely discover potential problems and guarantee the normal operation of the elevator.

[0040] Furthermore, a docking block is inserted into the docking groove 3. The top of the docking block is fixedly connected to the outer cover 22. A handle 23 is arranged at the top of the outer cover 22. The outer diameter dimension of the docking block matches the inner diameter dimension of the docking groove 3. An opening is arranged through the middle of the docking block, and the inner diameter dimension of the opening matches the outer diameter dimension of the lever 2.

[0041] An inspection and detection method for an elevator door lock includes the following operation steps:

[0042] S1. Ensure that the elevator is in a stopped state, and set obvious warning signs at the elevator hall door to prevent irrelevant personnel from accidentally taking the elevator. At the same time, prepare the required tools.

[0043] S2. Disassemble the elevator door lock and disconnect the connection between the elevator door lock and the elevator control system.

[0044] S3. Open the second box door 7, pour the cleaning liquid into the cleaning box 21, then place the elevator door lock on the placement rack 19 inside the cleaning box 21, and check whether the elevator door lock is submerged by the cleaning liquid. If it is not submerged, continue to add the cleaning liquid until it is submerged. Then start the ultrasonic generator 28 through the console 5. The ultrasonic generator 28 generates high-frequency electrical signals and transmits them to the ultrasonic transducer 27 through a cable. The ultrasonic transducer 27 converts the high-frequency electrical signals into mechanical energy and propagates them in the cleaning liquid to form ultrasonic waves. Ultrasonic cleaning uses high-frequency vibration to generate countless tiny bubbles in the cleaning liquid. When these bubbles burst on the surface of the door lock, they will generate a strong impact force, which can penetrate into various fine gaps and completely remove the dirt;

[0045] S4. After cleaning, take out the elevator door lock and place it at the placement rack 19 inside the water collecting trough 18. After the electric heating tube 17 is powered on, it generates heat to dry the elevator door lock, which avoids the chemical reaction between the residual moisture on the surface of the elevator door lock components and the oxygen in the air, resulting in the rusting of metal components. In addition, there are some electrical components and circuits in the elevator door lock, and drying them through the electric heating tube 17 can ensure that the electrical components and circuits are in a dry state, improving the electrical safety and reliability of the door lock;

[0046] S5. After drying, place the elevator door lock at the pneumatic clamp 11 on the top of the bottom plate 1, and clamp and fix the elevator door lock on the pneumatic clamp 11 on the top of the bottom plate 1 and the pneumatic clamp 11 at the bottom of the installation panel 12. The air cylinder 10 drives the telescopic rod 30 to contract upward, and at the same time pulls the tension sensor 31 to conduct a static tension test and display the tension data at the console 5. The tension sensor 31 can accurately sense and measure the magnitude of the applied tension and display the magnitude at the console 5, giving the staff an intuitive feeling, so as to judge whether the tension that the door lock can withstand under static conditions meets the safety standards;

[0047] S6. The telescopic rod 30 extends downward, and the staff can remove the elevator door lock on the pneumatic clamp 11;

[0048] S7. Install the elevator door lock back in place and restore the electrical connection. Then clean up the site, put away the tools, remove the warning signs, and resume the normal operation of the elevator.
