Description
Technical Field
[0001] This invention relates to the field of elevator testing technology, and in particular to a self-inspection mechanism for elevator wire ropes. Background Technology
[0002] Elevator wire rope tension balance is one of the core indicators to ensure the safe operation of the traction system. According to the requirements of TSG T5002-2017 "Elevator Maintenance Rules", maintenance units must conduct a quantitative inspection of the wire rope tension every six months, and the tension deviation between ropes in the same group shall not exceed 5%. At present, portable tension testing instruments are commonly used for self-inspection on site. During the test, maintenance personnel need to climb to the machine room and hook the rotating tension compression end (commonly known as "jaw") at the front end of the instrument onto the wire rope one by one. They then manually rotate the pressure screw to make the jaws generate a radial compression of about 0.5-1mm on the rope diameter. The internal strain gauges calculate the tension value of a single rope based on this and display it on the touch screen.
[0003] Since elevators typically have at least three steel wire ropes, with four to five being common, and high-speed, heavy-duty elevators even having eight to ten, existing tension self-testing instruments can only test one elevator steel wire rope at a time. As a result, operators must repeat the entire set of actions of "hooking the rope - rotating - reading - recording - loosening the clamp - moving," which takes a long time to test each rope and even longer overall. The entire process relies entirely on manual operation of each rope, which is not only labor-intensive and inefficient, but also poses a risk of falling due to frequent movement in narrow spaces at high altitudes.
[0004] Therefore, a self-inspection mechanism for elevator wire ropes is proposed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a self-inspection mechanism for elevator wire ropes.

A pair of lower plates are fixedly connected to the inner side of the sliding frame relative to the lower position of the U-shaped groove. An L-shaped plate is laterally slidably connected to the front side of the lower plate. A pair of sliding rods are fixedly connected to the front side of each self-test plate, and the sliding rods are set through the front side of the L-shaped plate. A detection mechanism is also provided for first driving the self-test plate to extend backward and then move to both sides to spread the steel wire rope for detection.
[0007] In the above technical solution, an upper spring is fixedly connected between the outer wall of the slide rod and the front side of the L-shaped plate, and a pair of lower springs are fixedly connected between the inner side of the slide frame and the side wall of the L-shaped plate.
[0008] In the above technical solution, further, both ends of the top of the U-shaped groove are fixedly connected to a limiting block, the top of the front side of the self-test plate is provided with a limiting groove, the bottom of the L-shaped self-test plate is provided with an upper inclined groove, and the bottom of the L-shaped plate on the side closest to each other is provided with a lower inclined groove.
[0009] In the above technical solution, a display screen is further provided on the front side of the detection frame, and the display screen is electrically connected to the pressure detector through the controller.
[0010] In the above technical solution, the detection mechanism further includes an upper bolt, which is threadedly connected to the bottom end of the slide frame. A maintenance plate is installed on the front side of the slide frame by bolts. An adjustment block is slidably connected to the rear side of the maintenance plate relative to the interior of the slide frame. A squeezing groove is opened at the top end of the rear side of the adjustment block. The top end of the upper bolt abuts against the bottom end of the adjustment block. Right-angle plates with inclined surfaces are fixedly connected to both sides of the outer wall of the adjustment block.
[0011] In the above technical solution, an L-shaped groove is further provided between the top end of the lower plate and the bottom end of the U-shaped groove, and a round rod is fixedly connected to the bottom end of the self-test plate, and the round rod is inserted into the inside of the L-shaped groove.
[0012] In the above technical solution, the locking mechanism further includes a lower bolt, three insert frames are fixedly connected to the front side of the locking plate, slots are provided on the rear side of the detection frame relative to the three insert frames, slots are provided on the side walls of the slots, and the rear side of the slots is inclined, an E-shaped groove is provided inside the locking plate, an E-shaped plate is slidably connected to the inner side of the E-shaped groove, and a locking block is fixedly connected to the branch side wall of the E-shaped plate, and the rear side of the locking block is inclined, a pair of lower bolts are provided, and the lower bolts are threaded through and connected to the side wall of the locking plate, and the side end of the lower bolt is rotatably connected to the side wall of the E-shaped plate.

The rear end of the pull pin is inserted into the inner side of one of the positioning holes, and a return spring is fixedly connected between the front side of the sliding frame and the outer wall of the pull pin.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the design of a detection frame, sliding frame, and detection mechanism, enables the rapid installation of multiple elevator wire ropes between the detection frame and the locking plate, placing the multiple wire ropes on the same reference plane. Subsequently, the detection mechanism squeezes two wire ropes to both sides for tension detection. The invention employs a centrally fixed, left-right bidirectional wedge structure, allowing both ropes to achieve the same deformation amount simultaneously. Symmetrical force application from both sides keeps the elastic body of the pressure detector in a "pressure-push-pressure" self-balancing state. Zero drift caused by temperature changes or rope diameter differences can be mutually canceled, resulting in higher detection accuracy and more convenient detection.
[0015] 2. Through the design of structures such as pull pins and detection mechanisms, this invention allows the detection end to be stored after the tension of two steel wire ropes has been tested. Then, the pull pin is pulled out to release the restriction of the sliding frame, which can then be moved to another pair of steel wire ropes for self-inspection. This allows for flexible adjustment and rapid self-inspection of multiple elevator steel wire ropes, eliminating the need for testing personnel to spend a lot of time on testing, and further improving the convenience of the device.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0020] In practical use, it was found that since the minimum number of elevator steel wire ropes is 3, and commonly 4-5, while high-speed, large-tonnage elevators can even have 8-10, the existing tension self-testing instrument can only test one elevator steel wire rope at a time. As a result, the operator must repeat the entire set of actions of "hooking the rope-rotating-reading-recording-releasing the clamp-moving". Each test takes a long time, and the overall time is even longer. The whole process relies entirely on manual operation of each rope, which is not only labor-intensive and inefficient, but also poses a risk of falling due to frequent movement in a narrow space at high altitude. To solve the above problems, the following structure was invented.
[0021] like Figures 1-10The elevator wire rope self-inspection mechanism shown includes a detection frame 1, which is U-shaped. Several upper semi-circular grooves 2 are formed through the top of the detection frame 1. A pair of locking plates 3 are provided at the rear end of the detection frame 1. Lower semi-circular grooves 4 are formed on the front side of the locking plates 3, opposite to the upper semi-circular grooves 2. A locking mechanism for locking the wire rope is provided between the detection frame 1 and the locking plates 3. A sliding groove 5 is formed through the front side of the detection frame 1. A sliding frame 6 is provided inside the sliding groove 5. Notches 7 are formed on both the upper and lower sides of the sliding frame 6, and the sliding frame 6 is laterally slidably connected to the sliding frame 6 through the notches 7. A U-shaped groove 8 is provided through the rear side of the sliding frame 6 inside the groove 5. A pair of L-shaped self-test plates 9 are provided inside the U-shaped groove 8. Pressure detectors 10 are fixedly connected to the opposite side of the self-test plates 9. A pair of lower plates 11 are fixedly connected to the inner side of the sliding frame 6 relative to the lower position of the U-shaped groove 8. An L-shaped plate 12 is slidably connected to the front side of the lower plate 11. A pair of sliding rods 13 are fixedly connected to the front side of the self-test plates 9, and the sliding rods 13 are set through the front side of the L-shaped plate 12. A detection mechanism is also provided for first driving the self-test plates 9 to extend backward and then move to both sides to spread the steel wire rope for detection. An upper spring 14 is fixedly connected between the outer wall of the slide rod 13 and the front side of the L-shaped plate 12. A pair of lower springs 15 are fixedly connected between the inner side of the slide frame 6 and the side wall of the L-shaped plate 12. With the setting of the upper spring 14 and the lower spring 15, the detection end can be quickly pushed to reset after the detection mechanism is reset. Both ends of the top of the U-shaped groove 8 are fixedly connected with limiting blocks 16, and the top front of the self-test plate 9 is provided with limiting grooves 17. With the setting of limiting blocks 16 and limiting grooves 17, after the detection mechanism pushes the self-test plate 9 to both sides, the limiting grooves 17 on the self-test plate 9 can be locked behind the limiting blocks 16, further restricting the forward movement and resetting of the self-test plate 9. The bottom of the L-shaped self-test plate 9 is provided with an upper inclined groove 18, and the bottom of the L-shaped plate 12 on the side closest to each other is provided with a lower inclined groove 19. A display screen 34 is provided on the front side of the detection frame 1. The display screen 34 is electrically connected to the pressure detector 10 through the controller. The testing mechanism includes an upper bolt 20, which is threadedly connected to the bottom of the slide frame 6. A maintenance plate 21 is installed on the front side of the slide frame 6 by bolts. An adjusting block 22 is longitudinally slidably connected to the rear side of the maintenance plate 21 relative to the interior of the slide frame 6. A pressing groove 23 is opened at the top of the rear side of the adjusting block 22. The top of the upper bolt 20 abuts against the bottom of the adjusting block 22. Right angle plates 24 with inclined surfaces are fixedly connected to both sides of the outer wall of the adjusting block 22. An L-shaped groove 25 is provided between the top of the lower plate 11 and the bottom of the U-shaped groove 8. A round rod 26 is fixedly connected to the bottom of the self-test plate 9, and the round rod 26 is inserted into the inside of the L-shaped groove 25. The L-shaped groove 25 and the round rod 26 can guide the sliding direction of the self-test plate 9, ensuring that the self-test plate 9 moves along the specified path. The locking mechanism includes a lower bolt 27. Three insert frames 28 are fixedly connected to the front side of the locking plate 3. Slots 29 are provided on the rear side of the detection frame 1 relative to the three insert frames 28. Slots 30 are provided on the side walls of the slots 29, and the rear side of the slots 30 is inclined. An E-shaped groove 31 is provided inside the locking plate 3. An E-shaped plate 32 is slidably connected to the inner side of the E-shaped groove 31. A block 33 is fixedly connected to the branch side wall of the E-shaped plate 32, and the rear side of the block 33 is inclined. A pair of lower bolts 27 are provided. The lower bolts 27 are threaded through and connected to the side wall of the locking plate 3. The side end of the lower bolt 27 is rotatably connected to the side wall of the E-shaped plate 32. When testing the tension of the wire rope, firstly, the testing frame 1 is clamped onto multiple wire ropes, and the wire ropes are placed in the upper semicircular groove 2. Then, the locking plate 3 is taken out and clamped onto the testing frame 1, and the wire ropes are clamped between the lower semicircular groove 4 and the upper semicircular groove 2. At the same time, the insertion frame 28 is inserted into the slot 29. Then, the lower bolt 27 is rotated so that the lower bolt 27 rotates outward spirally, which drives the E-type plate 32 to move laterally in the E-type groove 31. At the same time, the locking block 33 is inserted into the locking groove 30. During this process, the inclined surface of the locking block 33 will press against the inclined surface of the locking groove 30, so that the locking plate 3 is tightly locked onto the testing frame 1. Then, another locking plate 3 is installed on the testing frame 1 in the same way, so that the testing frame 1 is installed between multiple wire ropes, thereby ensuring that multiple wire ropes are on the same reference plane. The inspector then holds the inspection frame 1 with one hand and rotates the upper bolt 20 upwards with the other, thus pushing the adjusting block 22, which slides longitudinally at the rear end of the inspection plate 21, upwards. This causes the adjusting block 22 to press against the upper inclined groove 18 via the pressing groove 23. Since the sliding rod 13 on the self-inspection plate 9 passes through the sliding L-shaped plate 12, the sliding direction of the self-inspection plate 9 is restricted. Therefore, under the action of the pressing groove 23 pressing against the upper inclined groove 18, the self-inspection plate 9 is pushed backwards, simultaneously causing the sliding rod 13 to slide. And compress the upper spring 14. At the same time, it will drive the round rod 26 to slide at the vertical end of the L-shaped groove 25. Then, when the right angle plate 24 moves to the side of the lower inclined groove 19 on the L-shaped plate 12, the adjusting block 22 will push the self-test plate 9 completely out of the slide frame 6, so that the pressure detector 10 moves to the position between the two steel wire ropes. At the same time, it will drive the round rod 26 to the corner of the L-shaped groove 25, and squeeze the inclined groove 23 to move out from the side of the upper inclined groove 18. The rear end of the adjusting block 22 will move to the side of the upper inclined groove 18 to maintain the compression of the self-test plate 9. Then, as the adjusting block 22 continues to move upward, it will drive the right-angle plate 24 to move. The inclined surface of the right-angle plate 24 will press against the inclined groove 19. Since the L-shaped plate 12 can only move laterally on the lower plate 11, the pressure from the inclined surface of the right-angle plate 24 will push the two L-shaped plates 12 to move to both sides. At the same time, since the sliding rod 13 on the self-test plate 9 slides through the L-shaped plate 12, the movement of the L-shaped plate 12 will drive the self-test plate 9 to move together, gradually compressing the lower spring 15. In turn, the self-test plate 9 will drive the pressure detector 10 to move to both sides. The movement causes the pressure detector 10 to push the middle of the two steel wires to move to both sides. During this process, since the steel wire ropes are clamped between the upper semicircular groove 2 and the lower semicircular groove 4, the two steel wire ropes are squeezed from the middle to both sides, which will push the steel wire ropes from the clamping point to both sides, realizing the tension self-check of the elevator steel wire ropes. At the same time, the squeezing pressure will be detected by the pressure detector 10 and transmitted to the display screen 34 for display, thereby realizing the simultaneous detection of the two steel wire ropes. After the detection is completed, the upper bolt 20 is reversed and the above operation is repeated in the opposite direction to reset.
[0022] In summary, the above structural design allows for the rapid installation of multiple elevator wire ropes between the detection frame 1 and the locking plate 3, placing them on the same reference plane. The detection mechanism then presses the two wire ropes to both sides for tension testing. The use of a centrally fixed, left-right bidirectional wedge structure ensures that both ropes achieve the same deformation simultaneously. Symmetrical force application on both sides keeps the elastic body of the pressure detector 10 in a self-balancing state of "pressure-push-pressure," allowing zero drift caused by temperature changes or rope diameter differences to cancel each other out. This results in higher detection accuracy and greater convenience.
[0023] Based on the above embodiments, it was found during use that if the position of the sliding frame 6 cannot be adjusted, it is impossible to perform self-inspection on multiple wire ropes, which is quite limiting. To solve the above problem, further improvements were made to the above structure.
[0024] A pull pin 35 is slidably connected to the front side of the sliding frame 6. Several positioning holes 36 are equidistantly opened on the front side of the detection frame 1 relative to the rear position of the pull pin 35. The rear end of the pull pin 35 is inserted into the inner side of one of the positioning holes 36. A return spring 37 is fixedly connected between the front side of the sliding frame 6 and the outer wall of the pull pin 35. When it is necessary to change the detection position of the wire rope, first pull out the pull pin 35 and simultaneously stretch the return spring 37, so that the pull pin 35 is pulled out from the positioning hole 36, releasing the sliding restriction on the slide frame 6. Then, the slide frame 6 can be pushed to slide in the slide groove 5. Move the slide frame 6 to the side of another pair of wire ropes, and then release the pull pin 35. Then, under the elastic force of the return spring 37, push the rear end of the pull pin 35 into the corresponding positioning hole 36 to restrict the position of the slide frame 6. Then repeat the above operation to detect the tension of the wire rope.
[0025] In summary, the above structural design allows the testing end to be stored away after the tension testing of two wire ropes is completed. Then, the pull pin 35 is pulled out to release the restriction of the sliding frame 6, which can then be moved to another pair of wire ropes for self-testing. This allows for flexible adjustment and rapid self-testing of multiple elevator wire ropes without requiring testing personnel to spend a lot of time testing, further improving the convenience of the device.
