Description

[0003] The elevator traction machine is mainly composed of a cable and a pulley group. To ensure the safe operation of the elevator, the cable needs to be detected after the elevator has been used for a period of time. The main detection is the force deformation of the cable, that is, tension detection. In the prior art, when detecting the tension of the cable, a movable detection device is usually used for detection. During detection, the operator connects the detection device to the cable and manually rotates the feed bolt. The feed bolt drives the pressure sensor to push the cable to achieve the detection of the cable tension. However, the operator holds the detection device for detection, and the stability of the detection device is low. The cable is prone to tilt during detection, resulting in low accuracy of the detection result.

Detailed implementation manners

[0036] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Refer to Figures 1-4 , a reliability safety detection device for elevator parts, including a mounting base 1, which is connected to the elevator shaft bracket, and connecting ear seats 10 for fixedly connecting with the elevator shaft bracket are respectively installed at the upper and lower ends of the mounting base 1.

[0038] During specific operation, before the elevator is installed, the two connecting ear seats 10 on the mounting base 1 are respectively fixedly connected to the brackets fixed on the elevator shaft through existing bolts, so as to fix and limit the mounting base 1, and then the elevator is installed in the elevator shaft.

[0039] Refer to Figure 1 , Figure 2 andFigure 8 The reliability safety detection device for elevator components further includes a cable limiting group 2. Two cable limiting groups 2 are symmetrically arranged up and down and are simultaneously connected to the mounting base 1. The cable limiting group 2 includes a sliding channel 20 opened at the right end of the mounting base 1. A sliding part 21 is connected in the sliding channel 20. A horizontally arranged support rod 22 is installed on the sliding part 21. A limiting part 23 for cable limiting is connected to the support rod 22.

[0040] Refer to Figure 1 、 Figure 2 and Figure 8 The limiting part 23 includes a moving channel 230 opened on the support rod 22. A traction plate 231 is slidably connected through the moving channel 230. A connecting frame 232 is installed at the right end of the traction plate 231. A limiting roller 233 is rotatably connected to the connecting frame 232. The limiting part 23 further includes a limiting seat 234 installed at the right middle section of the connecting frame 232. An arc-shaped groove is opened at the right end of the limiting seat 234.

[0041] During specific operation, during elevator installation, the cable used for the elevator car is passed through between the upper limiting seat 234 and the limiting roller 233, and then passed out through between the lower limiting seat 234 and the limiting roller 233. When not detecting, the two limiting seats 234 and the two limiting rollers 233 play a guiding role in the sliding of the cable. The diameter of the channel formed between the arc-shaped groove at the right end of the limiting seat 234 and the limiting roller 233 is larger than the diameter of the cable, avoiding frictional loss to the use of the cable. The detection device fixedly installed on the elevator shaft can reduce the steps of connecting the cable during each detection, and prevent the phenomenon of the cable tilting during cable detection caused by the operator holding the detection equipment, thereby ensuring the accuracy of the detection result.

[0042] Refer to Figure 1 The reliability safety detection device for elevator components further includes a cable pushing group 4 for pushing the cable. The cable pushing group 4 is arranged between the two cable limiting groups 2.

[0043] Refer to Figure 1 、 Figure 2 and Figure 7 The cable pushing group 4 includes a hydraulic push rod 40 installed in the middle of the right end of the mounting base 1. The hydraulic push rod 40 is located between the two support rods 22. A pressure sensor 41 is installed at the right end of the hydraulic push rod 40. A pushing roller 42 is rotatably connected to the right end of the pressure sensor 41 through a roller frame. A blocking part 43 is connected to the front end of the roller frame.

[0044] During specific operation, connect the hydraulic push rod 40 to an existing hydraulic pump, and then electrically connect the pressure sensor 41 to an existing power supply, controller, and display. While the cable passes through between the two limit seats 234 and the two limit rollers 233, it is in contact with the pushing roller 42. When not detecting, the pushing roller 42 cooperates with the two limit seats 234 and the two limit rollers 233, and at the same time plays a role in guiding the sliding of the cable. After the elevator has been used for a period of time, conduct an initial length detection of the cable. Start the hydraulic push rod 40, and the hydraulic push rod 40 drives the roller frame to move through the pressure sensor 41. The roller frame drives the pushing roller 42 to push the cable. The cable is stressed and pushes the two limit rollers 233, and the two limit rollers 233 drive the two traction plates 231 to move.

[0045] Refer to Figure 2 and Figure 8 As shown in, the sliding channel 20 has a convex structure, and a plurality of limit slots 200 are opened on both middle sections of the sliding channel 20.

[0046] Refer to Figure 8 and Figure 9 As shown in, the sliding part 21 includes a sliding plate 210 slidably connected in the sliding channel 20. A sliding slot 211 is opened at the right end of the sliding plate 210. A moving plate 212 is slidably connected in the sliding slot 211. A plurality of limit protrusions 213 cooperating with the corresponding limit slots 200 are installed at the right end of the moving plate 212. The left end of the traction plate 231 is fixedly connected to the moving plate 212.

[0047] Refer to Figure 8 and Figure 9 As shown in, the sliding part 21 further includes two guiding slots 214 opened on the front and rear slot walls of the sliding slot 211. A guiding block 215 is slidably connected in the guiding slot 214. The guiding block 215 is fixedly connected to the moving plate 212. A plurality of return springs 216 are installed between the moving plate 212 and the left slot wall of the sliding slot 211.

[0048] Refer to Figure 1 and Figure 8 As shown in, the cable limiting group 2 further includes a reinforcing rod 25 with two ends respectively fixedly connected to the sliding plate 210 and the support rod 22 and in an inclined state.

[0049] During specific operation, two traction plates 231 drive two moving plates 212 to slide in the corresponding two sliding grooves 211. Meanwhile, the moving plates 212 move in the corresponding two guiding grooves 214 through two guiding blocks 215. The moving plates 212 drive the corresponding multiple limiting protrusions 213 to be clamped and matched with the corresponding limiting grooves 200 and stretch the corresponding multiple reset springs 216, further realizing the function of limiting the sliding plate 210, effectively improving the accuracy of the positions of the support rod 22 and the limiting part 23, ensuring the accurate detection length of the cable this time, and then improving the accuracy of the detection result. At the same time, a stable triangular structure is formed among the support rod 22, the reinforcing rod 25, and the sliding plate 210, realizing the stability of the support for the limiting part 23, and then improving the stability of the force on the cable during detection. The limiting roller 233 can effectively adjust adaptively with the degree of bending of the cable during the cable detection process, and increase the contact area with the cable, effectively avoiding the phenomenon of the cable having a fold angle, and then avoiding damaging the cable during the detection process.

[0050] After multiple limiting protrusions 213 are clamped and matched with the corresponding limiting grooves 200, the position of the limiting roller 233 no longer moves. Then, the pushing roller 42 continues to push the cable. The cable is bent under force and applies pressure to the pressure sensor 41. The pressure sensor 41 is stressed and sends an electrical signal to the controller. The controller controls the display to display the corresponding value through the electrical signal. This is the prior art. When the pressure sensor 41 reaches the preset threshold, observe the situation of the cable and record the detection result. If the cable has no change, the cable continues to be used. If the cable shows a shrinking phenomenon, replace the cable.

[0051] Refer to Figure 1 、 Figure 2 and Figure 7 As shown in FIGS.

[0052] Refer to Figure 1 、 Figure 2 and Figure 7 The blocking part 43 further includes a transverse movement plate 434 fixedly connected to the left end of the limiting rod 432. Both the upper and lower ends of the transverse movement plate 434 are hinged with a connecting rod 435. One end of the connecting rod 435 away from the transverse movement plate 434 passes through the corresponding sliding through hole 430 and is hinged with the corresponding sliding plate 210.

[0053] During specific operation, the limiting rod 432 has a horizontal T-shaped structure. In the initial state, the distance from the right end of the limiting rod 432 is the maximum distance that the pushing roller 42 moves during this inspection, and it is also the maximum value of the force on the cable during the cable tension detection, avoiding damage to the compliant cable during the detection. While the hydraulic push rod 40 drives the roller frame to move through the pressure sensor 41, it also drives the limiting block 431 to move. The limiting block 431 cooperates with the vertical section of the limiting rod 432 to realize the function of limiting the moving length of the roller frame.

[0054] After the cable tension detection of this detected length is completed, the hydraulic push rod 40 drives the roller frame to reset through the pressure sensor 41, and then drives the pushing roller 42 to reset. The multiple reset springs 216 in the stretched state reset and drive the moving plate 212 to reset, thereby releasing the clamping state between the limiting protrusion 213 and the corresponding limiting groove 200, facilitating the sliding of the sliding plate 210 later.

[0055] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in, the elevator component reliability safety detection device further includes a distance adjustment group 3. The distance adjustment group 3 is connected to the mounting base 1 and is used to adjust the distance between the two cable limiting groups 2.

[0056] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in, the distance adjustment group 3 includes a bidirectional drive motor 30 fixedly connected to the mounting base 1 through a motor base. Adjusting screws 31 are installed on both output shafts of the bidirectional drive motor 30.

[0057] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown in, a lifting part 24 is connected to the rear end of the support rod 22. The lifting part 24 includes a lifting plate 240 installed at the rear end of the support rod 22. An adjustment through hole is opened on the lifting plate 240. A fine adjustment groove 244 is opened in the middle section of the adjustment through hole. An adjustment plate 241 is slidably connected in the fine adjustment groove 244. A plurality of stable springs 242 are installed between the upper and lower ends of the adjustment plate 241 and the upper and lower groove walls of the fine adjustment groove 244 respectively. A threaded sleeve 243 is installed through the middle of the adjustment plate 241, and the threaded sleeve 243 is threadedly connected to the adjusting screw 31.

[0058] ​​​​​During specific operation, the bidirectional drive motor 30 is an existing dual-axis motor. Connect the bidirectional drive motor 30 to an existing power source. After the initial length of the cable is detected, start the bidirectional drive motor 30. The bidirectional drive motor 30 drives two pitch-adjusting screws 31 to rotate. The two pitch-adjusting screws 31 drive two threaded sleeves 243 to move. The threaded sleeves 243 push the lifting plate 240 through the adjusting plate 241. The lifting plate 240 drives the corresponding support rod 22 to move. The support rod 22 drives the sliding plate 210 to slide in the sliding channel 20. While the two sliding plates 210 slide, they drive two connecting rods 435 to move. The two connecting rods 435 drive the limit rod 432 to move on the positioning seat 433 and the limit block 431 through the transverse movement plate 434, so as to meet the requirements of the maximum force on the cable during subsequent tension detection.

[0059] After the support rod 22 moves to the required position, repeat the previous steps of cable tension detection. During the process of the multiple limit protrusions 213 being re-engaged with the corresponding limit grooves 200, if the position of the support rod 22 is inaccurate due to the reasons of the bidirectional drive motor 30 itself after the bidirectional drive motor 30 drives the support rod 22 to stop moving, the sliding plate 210 drives the support rod 22 to move. The support rod 22 drives the fine adjustment groove 244 to move on the adjusting plate 241 through the lifting plate 240, so as to realize the fine adjustment of the position of the support rod 22 and ensure that it is in the accurate position for detection. Then repeat the previous cable detection steps and record the detection results.

[0060] Subsequently, repeat the previous two steps of adjusting the distance between the two support rods 22 and the cable detection steps again until the cable tension conditions at different lengths are tested, effectively increasing the detection samples and further improving the accuracy of the detection results. At the same time, the cable detection position is adjustable, effectively improving the applicability of the detection equipment, and the detection is completed.
