Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing and installation, in particular to a fixing structure for an elevator accompanying cable. Background Art

[0002] Elevator traveling cables are cables used to transmit communication signals and power in elevator systems. They undertake the key task of efficiently transmitting control signals, data information, and electrical energy between the elevator machine room control cabinet and the moving elevator car. One end is firmly connected to the control cabinet in the elevator machine room, and the other end is carefully fixed to the elevator car to ensure that it can flexibly expand and contract as the car moves up and down. With the rapid development of modern construction technology, the height of buildings continues to break through the sky, prompting the length of elevator traveling cables to increase accordingly to meet the needs of seamless communication and control between higher floors.

[0003] The existing patent (publication number: CN220316986U) discloses that "the utility model relates to the technical field of installation of cables or wires, and discloses an elevator accompanying cable fixing structure, including a positioning frame, the cross-section of the positioning frame is in the shape of an "n", and a connecting plate is slidably connected between the two vertical plates of the positioning frame. The left surface of the two vertical plates of the positioning frame is provided with two positioning grooves extending from its right surface, and the left and right side surfaces of the connecting plate are fixedly connected with two positioning blocks adapted to the positioning grooves, and the positioning blocks are slidably connected to the positioning grooves. The elevator accompanying cable fixing structure drives the positioning block to move backward under the action of the released elastic force of the spring, and then drives the connecting plate to squeeze and fix the accompanying cable, and then fixes the accompanying cable between the rubber pad and the horizontal plate of the positioning frame. This fixing method only requires pulling and pulling the handle to dismantle and fix the accompanying cable, without removing the bolts, which is more convenient and quick, thereby improving the maintenance and installation efficiency of the accompanying cable."

[0004] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

[0005] This device mainly uses a single spring force to fix the cable. During long-term use, the spring may become elastically fatigued, affecting the fixing effect. In addition, when the cable is subjected to large vibrations, the switch may be accidentally touched due to the small number of springs. At the same time, the spring of the device is located outside and is easily affected by the movement of the elevator, increasing the wear and failure risk of the spring.

[0006] Therefore, those skilled in the art provide an elevator traveling cable fixing structure to solve the problems raised in the above background technology. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an elevator traveling cable fixing structure. By operating the handle in the fixing mechanism, the cable can be quickly fixed and released, thereby improving work efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] An elevator accompanying cable fixing structure includes an installation frame, wherein a fixing mechanism is provided inside the installation frame, and the fixing mechanism includes a handle, a switch, a fixing block, two sliders, a rubber block, two limit blocks, two first springs, four second springs, two connecting blocks, two moving blocks, two third springs and two connecting ropes;

[0010] A cable main body is clamped and arranged inside the installation frame, a mounting block is fixedly arranged on the upper end of the rear end of the installation frame, and two buzzers are fixedly arranged on the lower end of the rear end of the installation frame.

[0011] Furthermore, the front ends of the two connecting blocks are fixedly arranged at the rear end of the handle, the outsides of the two connecting blocks are respectively slidably arranged on both sides of the inside of the installation frame, and the opposite sides of the outsides of the two sliders are respectively slidably arranged inside the opposite sides of the two connecting blocks.

[0012] Furthermore, the two sliding blocks are fixedly arranged on opposite sides of the fixing block, the outside of the fixing block is slidably arranged inside the installation frame, and the front end of the rubber block is fixedly arranged on the rear end of the fixing block.

[0013] Furthermore, the front ends of the four second springs are fixedly arranged at the front end inside the installation frame, the rear ends of the four second springs are fixedly arranged at the front end of the fixing block, and the front end of the switch is fixedly arranged at the front end inside the installation frame.

[0014] Furthermore, the opposite ends of the two limit blocks are rotatably arranged at the upper and lower ends inside the installation frame, the rear ends of the two first springs are fixedly arranged at the front ends of the two limit blocks, and the front ends of the two first springs are fixedly arranged at the upper and lower ends inside the installation frame.

[0015] Furthermore, the rear ends of the two connecting ropes are respectively fixed to the front ends of the two limit blocks, the front ends of the two connecting ropes are respectively fixed to the opposite sides of the two moving blocks, the opposite sides of the two third springs are respectively fixed to the opposite sides of the two moving blocks, and the opposite sides of the two third springs are respectively fixed to the inside of the handle near both ends.

[0016] Furthermore, the exteriors of the two moving blocks are both slidably arranged inside the handle, and the exteriors of the two connecting ropes are respectively slidably arranged inside the mounting frame and the handle.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model proposes an elevator accompanying cable fixing structure. During installation, the handle is pulled to make the connecting block slide inside the installation frame, and the slider follows the movement, thereby driving the fixing block to slide synchronously. The movement of the fixing block will squeeze the second spring to shrink it. When the fixing block moves to a suitable position, the cable body is passed through the installation frame, and then the pulling force on the handle is released. The second spring pushes the fixing block to reset, so that the rubber block at the rear end of the fixing block squeezes the cable body to complete the fixation of the cable body. This simplifies the cable fixing operation process, improves the convenience of operation, and improves the stability of the cable during elevator operation, avoiding loosening due to vibration.

[0019] 2. The utility model proposes an elevator accompanying cable fixing structure. When the cable is pulled by a protrusion during the operation of the elevator, the cable body will push the rubber block and the fixed block to move, causing the fixed block to slide and at the same time squeeze the second spring. As the fixed block moves, its outer portion will squeeze the limit block, causing the limit block to rotate, causing the first spring to contract. When the fixed block moves to a specific position, its front end will directly touch and squeeze the switch, causing the switch to control the elevator to stop running. At the same time, the buzzer will sound an alarm, thereby avoiding elevator safety accidents caused by cable problems. At the same time, when the fixed block moves to the final specific position, the squeezing of the limit block will be released, causing the first spring to rebound, driving the limit block to reset, so that the limit block limits the fixed block, thereby maintaining the position of the fixed block until maintenance personnel intervene, facilitating subsequent operations, and improving the safety of the elevator operation.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-5 , an embodiment provided by the utility model:

[0029] A fixing structure for an elevator accompanying cable includes a mounting frame 2, wherein a fixing mechanism 4 is provided inside the mounting frame 2, wherein the fixing mechanism 4 includes a handle 401, a switch 402, a fixing block 403, two sliders 404, a rubber block 405, two limit blocks 406, two first springs 407, four second springs 408, two connecting blocks 409, two moving blocks 410, two third springs 411 and two connecting ropes 412. The front ends of the two connecting blocks 409 are fixedly arranged at the rear end of the handle 401, the outsides of the two connecting blocks 409 are respectively slidably arranged on both sides of the inside of the mounting frame 2, the opposite sides of the outsides of the two sliders 404 are respectively slidably arranged inside the opposite sides of the two connecting blocks 409, the opposite sides of the two sliders 404 are fixedly arranged on both sides of the fixing block 403, the outside of the fixing block 403 is slidably arranged inside the mounting frame 2, the front end of the rubber block 405 is fixedly arranged at the rear end of the fixing block 403, and the front ends of the four second springs 408 are all fixedly arranged on the mounting frame 2 internal front end, the rear ends of the four second springs 408 are fixedly arranged at the front end of the fixed block 403, the front end of the switch 402 is fixedly arranged at the front end of the installation frame 2, the opposite ends of the two limit blocks 406 are respectively rotatably arranged at the upper and lower ends of the installation frame 2, the rear ends of the two first springs 407 are respectively fixedly arranged at the front ends of the two limit blocks 406, the front ends of the two first springs 407 are respectively fixedly arranged at the upper and lower ends of the installation frame 2, the rear ends of the two connecting ropes 412 are respectively fixedly arranged at the front ends of the two limit blocks 406, the front ends of the two connecting ropes 412 are respectively fixedly arranged at the opposite sides of the two moving blocks 410, the opposite sides of the two third springs 411 are respectively fixedly arranged at the opposite sides of the two moving blocks 410, the opposite sides of the two third springs 411 are respectively fixedly arranged at the two ends of the handle 401, the outsides of the two moving blocks 410 are both slidably arranged inside the handle 401, and the outsides of the two connecting ropes 412 are respectively slidably arranged inside the installation frame 2 and the handle 401;

[0030] Specifically, when it is necessary to fix the cable, first fix the mounting block 1 to the lower end of the elevator, and then pull the handle 401 to make the two connecting blocks 409 connected thereto start to slide inside the mounting frame 2, and transmit synchronously through the slider 404 inside the connecting block 409. The movement of the slider 404 directly drives the fixed block 403 connected thereto to slide synchronously, and the movement of the slider 404 will provide a guiding effect. The movement of the fixed block 403 will squeeze the second spring 408 at the same time, causing it to shrink inside the mounting frame 2. The movement of the fixed block 403 will further squeeze the limit block 406, causing the limit block 406 to rotate around the axis and causing the first spring 407 to shrink. At the same time, the movement of the handle 401 drives the two moving blocks 410 to slide inside it, and the moving block 410 squeezes the third spring 411. When the components move to the appropriate position, the cable body 3 is passed through the interior of the mounting frame 2. When the pulling force on the handle 401 is released, the second spring 408 rebounds, pushing the fixed block 403 and the slider 404 to slide and reset inside the installation frame 2. As the fixed block 403 is reset, the first spring 407 rebounds, driving the limit block 406 to reset. At the same time, the third spring 411 rebounds, driving the connecting rope 412 to reset through the moving block 410. At this time, the rubber block 405 at the rear end of the fixed block 403 gradually squeezes the cable body 3 to complete the fastening of the cable, reducing the operation steps, eliminating the need for additional tools, reducing the difficulty of operation, and improving the speed and efficiency of cable fixing. At the same time, multiple springs ensure that the cable remains stable during long-term use, effectively avoiding spring elastic fatigue, and not only simplifying the cable fixing operation process, but also improving the convenience of user operation, and improving the stability of the cable during elevator operation to avoid loosening due to vibration;

[0031] When the cable is pulled by a protrusion during elevator operation, the cable body 3 will be affected by external force. The cable body 3 is subjected to the pulling force, pushing the rubber block 405 and the fixed block 403 in close contact with it to move forward. The movement of the fixed block 403 drives the sliders 404 on both sides to slide inside the connecting block 409, while squeezing the second spring 408, causing the spring to shrink inside the installation frame 2, alleviating the pulling force. As the fixed block 403 moves, it begins to squeeze the limit block 406, prompting the limit block 406 to rotate and causing the first spring 407 to shrink inside the installation frame 2. When the fixed block 403 moves to a specific position, it will directly touch and squeeze the switch 402, triggering the safety mechanism. Switch 402 controls the elevator to stop running, thereby reducing cable damage and avoiding elevator safety accidents caused by cable problems. How switch 402 controls the elevator to stop running is an existing technology, so it will not be explained in detail in this manual. At the same time, the movement of the fixed block 403 will squeeze the limit block 406, causing the first spring 407 to rebound, driving the limit block 406 to reset, and the limit block 406 rotates to limit the fixed block 403 and maintain its position until maintenance personnel intervene. When the maintenance is completed, the handle 401 is pulled to drive the connecting rope 412 to move, causing the limit block 406 to rotate, so that the limit block 406 releases the limit on the fixed block 403, which is easy to operate.

[0032] Reference Figure 1-3 The cable body 3 is fixed inside the mounting frame 2, the mounting block 1 is fixed on the upper end of the rear end of the mounting frame 2, and two buzzers 5 are fixed on the lower end of the rear end of the mounting frame 2;

[0033] Specifically, when the cable follows the movement of the elevator and is pulled, the fixed block 403 squeezes the switch 402, so that the buzzer 5 is activated and an alarm is sounded. The activation of the buzzer 5 promptly reminds maintenance personnel to conduct inspections, thereby increasing safety in use.

[0034] Working principle: When the cable needs to be fixed, by pulling the handle 401, it drives the connecting block 409 to slide inside the installation frame 2. The movement of the connecting block 409 will drive the slider 404 inside it to move synchronously. Since the slider 404 is connected to the fixed block 403, when the slider 404 moves, it will drive the fixed block 403 to move synchronously. When the fixed block 403 moves, it will squeeze the second spring 408 connected to it, causing it to shrink inside the installation frame 2. The movement of the fixed block 403 will also squeeze the limiting block 406 inside the installation frame 2, causing it to rotate and causing the first spring 407 to shrink. At the same time, the movement of the handle 401 will cause the moving block 410 to slide inside the handle 401 and squeeze the third spring 411. When the fixed block 403 moves to the appropriate position, The cable body 3 is passed through the interior of the installation frame 2. At this time, the tension on the handle 401 is released, so that the second spring 408 rebounds and pushes the fixed block 403 to slide inside the installation frame 2. The movement of the fixed block 403 will synchronously drive the slider 404 and the connecting block 409 to move. The movement of the connecting block 409 will drive the handle 401 to reset. When the fixed block 403 moves to a certain position, the squeezing of the limit block 406 will be gradually released, so that the first spring 407 rebounds and drives the limit block 406 to reset. At the same time, the movement of the handle 401 will cause the third spring 411 to rebound, so that the moving block 410 drives the connecting rope 412 to reset, so that the connecting rope 412 remains taut. When the fixed block 403 is reset, the rubber block 405 at its rear end will gradually squeeze the cable body 3, thereby completing the fixing operation of the cable body 3.

[0035] Secondly, when the cable is pulled by the protrusion as the elevator rises and falls, the cable body 3 will be subjected to a pulling force, causing the cable body 3 to push the rubber block 405 and the fixed block 403 that squeeze it to move forward, thereby causing the sliders 404 on both sides of the fixed block 403 to slide inside the connecting block 409, and the movement of the fixed block 403 will squeeze the second spring 408 connected to it, causing it to shrink inside the installation frame 2. At the same time, the movement of the fixed block 403 will gradually squeeze the limit block 406, causing the limit block 406 to The first spring 407 is rotated, thereby contracting the first spring 407 inside the installation frame 2. When the fixed block 403 moves to the final position, it squeezes the switch 402, causing the switch 402 to control the elevator to stop running, and the two buzzers 5 at the rear end of the installation frame 2 sound an alarm. At the same time, the movement of the fixed block 403 will contact the limit block 406 and squeeze it, causing the first spring 407 to rebound and drive the limit block 406 to reset, thereby causing the limit block 406 to rotate, thereby limiting the fixed block 403.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
