Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an elevator with a safety warning function. Background Art

[0002] Elevators are vertical transportation equipment commonly used in construction, cargo handling and high-altitude operations. They are mainly used to carry people, construction materials, tools, etc. to move quickly between different heights. They are especially suitable for material transfer and personnel up and down during high-rise building construction. They can greatly improve work efficiency and reduce labor costs. At the same time, they also play a key role in connecting different floors and realizing vertical transportation in warehousing, industrial production and other scenarios.

[0003] Elevators primarily rely on a power system (such as a motor) to provide driving force. This power is transmitted through a speed reducer to a winch or hydraulic device, which in turn drives a wire rope or chain to pull the car (or platform) vertically up and down along a fixed track (such as a frame rail). The direction and speed of the car are regulated by a control system (such as operating buttons and a frequency converter). Braking devices are also used to ensure safe operation. Some elevators also use counterweights to balance the car's weight, reducing power consumption and ensuring that it can stably and accurately stop at a specified height even when carrying different loads.

[0004] When using existing elevators, they need to be installed outside the building and lift vertically up and down along the outer wall of the building. However, during the lifting process, if the building materials inside the building extend outside, such as steel pipes or scraps extending outside the building, they may interfere with the elevator, easily causing scratches and damage to the elevator. If the extended obstacle is large, it is more likely to cause the elevator to get stuck, causing safety hazards and affecting people's use. Summary of the Invention

[0016] By adopting the above technical solution, the contact roller is set on one side of the wire rope and close to the wall. When in use, the contact roller is in contact with the wall, and the wire rope passes horizontally in the dial ring. When the inner rod moves downward, the wire rope is pulled downward through the dial ring.

[0017] Furthermore, the micro-trigger assembly includes a connecting base fixedly connected to one side of the mounting frame, the top of the connecting base is fixedly connected to a micro switch, the inner side of the connecting base is fixedly connected to a telescopic rod, a tension spring is provided on the telescopic rod, and the bottom of the telescopic rod is fixedly connected to a touch member.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. In the present application, an alarm mechanism and a steel wire rope are provided at the top and bottom ends of the elevator body. The steel wire rope is in a straight state under the action of the internal components of the alarm mechanism. If the elevator body moves upward or downward and encounters an extended obstacle, the steel wire rope will press against the obstacle as the elevator moves, causing the steel wire rope to be pressed downward, thereby pulling and driving the alarm mechanism, thereby triggering the alarm, thereby warning the surrounding staff so that the staff can control the elevator body in time, preventing the elevator body from being scratched by extended obstacles during operation, and improving the safety of the elevator.

[0029] 2. In the present application, an elastic contact member is provided on the elastic linkage member and is installed on the side of the wire rope that may contact the obstacle. Through its internal components, it can elastically resist the wall in real time. When there is an obstacle, the elastic contact member can first contact the obstacle and evenly transfer the force to the wire rope, so that the wire rope presses down to drive the alarm mechanism, which can trigger the alarm, thereby expanding the detection range of the wire rope, making the wire rope more sensitive to tiny obstacles extending from the wall, improving the stability of the contact between the wire rope and the obstacle, and thus improving the accuracy of the wire rope in obstacle detection. At the same time, the combination of the elastic contact member and the elastic linkage member can buffer the instantaneous impact force generated when contacting the obstacle, avoiding damage to the components, and at the same time, buffering and protecting the wire rope to avoid excessive wear or collapse of the wire rope. At the same time, the mutual cooperation of the elastic contact member and the wire rope prevents the wire rope from being misjudged or missed due to excessive local stress or poor contact at the contact point when it is affected by the obstacle, further improving the accuracy of obstacle detection, thereby improving the accuracy of the early warning and improving the safety of the elevator.

[0030] 3. In the present application, when the elastic contact piece is affected by an obstacle and presses the wire rope, the wire rope can be restricted and guided by the pressing guide piece, so that the pressing guide piece can accurately guide the wire rope, reduce the wear of the wire rope during the pulling operation, maximize the service life of the wire rope, and reduce the replacement frequency of the wire rope. At the same time, as the force of the obstacle on the wire rope continues to increase, the elastic contact piece synchronously drives the elastic linkage piece, so that the internal components of the elastic linkage piece can operate, and can synchronously drive the pressing guide piece, so that the internal components of the pressing guide piece can operate. The steel wire rope is compressed and conveyed, and as the elastic linkage continuously drives the compression guide, and the two cooperate with each other, the steel wire rope is dynamically compressed and guided, so that the compression pressure applied by the compression guide on the steel wire rope is continuously enhanced, further improving the stability of the steel wire rope movement between the bracket, traction frame and alarm mechanism, and preventing the steel wire rope from shaking and deflecting when running on a fixed track when it is pressed downward by the force, so that the steel wire rope can stably pull the alarm mechanism to avoid false triggering or missed detection, thereby further improving the accuracy and stability of the early warning and improving the safety of the elevator.

[0031] 4. In the present application, when the elastic contact member drives the wire rope downward, it can synchronously drive the elastic linkage member, so that the internal components of the elastic linkage member synchronously drive the micro-trigger assembly, so that the elastic linkage member drives the corresponding micro-trigger assembly, so that the internal components of the micro-trigger assembly trigger its internal switch mechanism, which can touch the switch mechanism to turn on the corresponding warning light inside the elevator body. The staff can judge the size and location of the obstacle based on the number and order of the triggered warning lights. A single warning light is triggered to indicate a small obstacle. Multiple warning lights are triggered in sequence to infer the distribution length of the obstacle along the direction of travel of the elevator body. In this way, the size and location of the obstacle can be roughly detected. This can be combined with the touch detection of the wire rope to achieve multi-dimensional signal coordinated output. The staff can not only receive an obstacle warning, but also judge the risk level through the feedback of the micro-trigger assembly. For example, a large obstacle requires an emergency stop, while a small one can be slowly avoided. This achieves an upgrade from risk discovery to risk identification, achieving more accurate early warning of obstacles, maximizing the accuracy of the early warning, and thus improving the safety of the elevator.

[0032] 5. In the present application, when the obstacle disappears, the internal elastic component of the elastic linkage can realize its own rapid rebound reset, which can drive the elastic contact member to quickly reset, so that the wire rope moves upward and the auxiliary wire rope is straightened again. At the same time, the internal elastic component of the micro-trigger assembly can realize its own rapid reset when the resistance force of the elastic linkage is lost. When the elastic linkage is reset, the drive to the pressing guide can be released, so that the internal component of the pressing guide is reset, and then the synchronous reset of each component is realized through the reset of the elastic linkage, reducing the possibility of secondary false alarms caused by asynchronous reset of components, avoiding misjudgment of the next detection caused by the reset lag of a single component, and improving the accuracy of subsequent obstacle detection.

DETAILED DESCRIPTION

[0048] The following is combined with Figures 1 to 13 This application is described in further detail.

[0049] An embodiment of the present application discloses an elevator with a safety warning function.

[0050] Reference Figures 1 to 6A lift with a safety warning function includes a lift body 1, a connecting frame 2 is fixedly connected to the top and bottom of the lift body 1, an alarm mechanism 3 is fixedly connected to one side of the connecting frame 2, a traction frame 22 is fixedly connected to one side of the connecting frame 2, and a mounting frame 21 is fixedly connected to the other side of the connecting frame 2, one end of the connecting frame 2 is fixedly connected to a bracket 23, a steel wire rope 4 is fixedly connected to the alarm mechanism 3, the steel wire rope 4 is sequentially wound around the traction frame 22 and the bracket 23, and one end of the steel wire rope 4 is fixedly connected to the traction frame 22 and the bracket 23. The end is fixedly connected to the bracket 23 on one side. Here, a section of the wire rope 4 is located between the two brackets 23. The wire rope 4 and the two brackets 23 are both arranged on the side close to the wall. Through this section of the wire rope 4, it can contact the obstacle, and a guide pulley is provided at the top of the bracket 23 to guide the wire rope 4, so that it is convenient to pull the alarm mechanism 3 when the wire rope 4 is hit by an obstacle. The wire rope 4 is made of high-carbon steel wire and fiber rope core, which has strong wear resistance, improves the hardness, tensile strength and Anti-wear ability, an elastic linkage part 7 is fixedly connected to the mounting frame 21, and an elastic contact part 6 is installed on the top of the elastic linkage part 7, and the elastic contact part 6 and the wire rope 4 conflict with each other, and a plurality of micro-trigger components 8 are fixedly connected to the bottom of the mounting frame 21, and the micro-trigger component 8 corresponds to the elastic linkage part 7. A pressing guide 5 is fixedly connected to one side bracket 23, and the pressing guide 5 and the wire rope 4 contact each other. The pressing guide 5 is transmission-connected to the elastic linkage part 7, and a control panel is provided on the inner side of the elevator body 1, and the control panel is electrically connected to the micro-trigger component 8 and the alarm mechanism 3. When the alarm mechanism 3 is triggered by the wire rope 4, the alarm mechanism 3 can send a warning signal to the control panel and issue an alarm to the outside at the same time, so as to warn the staff inside the elevator body 1 and the staff at the construction site. When the micro-trigger component 8 is triggered, the micro-trigger component 8 can also transmit the trigger signal to the control panel, so that the staff can check the approximate position of the obstacle.

[0051] The alarm mechanism 3 includes a guide rail 31 fixedly connected to one side of the connecting frame 2, the inner top of the guide rail 31 is fixedly connected to a touch sensing block 34, and the inner bottom of the guide rail 31 is slidably connected to a counterweight block 32, one side of the counterweight block 32 is rotatably connected to a pulley 33 that is symmetrical with each other, the top of the counterweight block 32 is fixedly connected to the wire rope 4, and one side of the guide rail 31 is fixedly connected to an alarm 35, which is electrically connected to the touch sensing block 34. Here, the friction between the counterweight block 32 and the guide rail 31 can be reduced by rolling the pulley 33 with the side wall of the guide rail 31, so that the movement of the counterweight block 32 is smoother and smoother. The counterweight block 32 can be pulled by the wire rope 4 so that the counterweight block 32 contacts the touch sensing block 34. When in contact, the touch sensing block 34 can convert the force generated by the contact into an electrical signal, and transmit the sensing signal to the alarm 35 through the touch sensing block 34, so that the alarm 35 can be triggered to sound an alarm.

[0052] When the lift body 1 is lifted and lowered, the upper and lower connecting frames 2 of the lift body 1 are driven to move, thereby driving the wire rope 4 and the alarm mechanism 3 to move along with the lifting and lowering of the lift body 1. During this period, the internal components of the elastic contact member 6 are operated so that the elastic contact member 6 always maintains elastic resistance against the wall. When there is an obstacle on the wall, the elastic contact member 6 can first resist the obstacle, so that the elastic contact member 6 moves downward under the resistance reaction force of the obstacle, thereby pulling the wire rope 4 downward, so that the wire rope 4 moves along the bracket 23 and the traction frame 22 on one side, and pulling the alarm mechanism 3, thereby causing one end of the wire rope 4 to pull the counterweight block 32, so that the counterweight block 32 moves upward, thereby resisting the touch sensing block 34. The touch sensing block 34 sends a signal to the alarm 35. After receiving the signal, the alarm 35 can sound an alarm to warn the surrounding staff and send an alarm signal to the remote terminal so that the staff can deal with the elevator body 1 in time, thereby realizing the detection and early warning of obstacles, thereby improving the safety of the elevator operation. When the internal components of the elastic contact piece 6 are in contact with the wall, it is convenient to detect small obstacles extending from the wall, thereby improving the accuracy of detection. During the period when the wire rope 4 pulls the counterweight block 32, the wire rope 4 is limited and guided by the compression guide piece 5 to avoid unnecessary wear of the wire rope 4 when it moves, reduce the wear of the wire rope 4 during the pulling work, maximize the service life of the wire rope 4, and reduce the replacement frequency of the wire rope 4.

[0053] When the corresponding elastic contact member 6 contacts the obstacle and moves downward, it can drive the elastic linkage member 7 to operate, so that the internal components of the elastic linkage member 7 drive the micro-trigger component 8, so that the internal components of the micro-trigger component 8 extend, and then drive the switch mechanism inside the micro-trigger component 8, which can be touch-activated to turn on the corresponding warning lights inside the elevator body 1. The staff can judge the size and position of the obstacle according to the number and sequence of the triggered warning lights. A single warning light is triggered to prompt a small obstacle. Multiple warning lights are triggered in sequence to infer the distribution length of the obstacle along the running direction of the elevator body 1. In this way, the size and position of the obstacle can be roughly detected, which can be combined with the touch detection of the wire rope 4 to provide a more accurate warning of the obstacle, maximize the accuracy of the warning, and thus improve the safety of the elevator.

[0054] While the elastic contact member 6 drives the elastic linkage member 7 to press down and drive the micro-trigger assembly 8, the elastic linkage member 7 can simultaneously drive the pressing guide member 5, so that the internal components of the pressing guide member 5 are in operation and the internal components are stretched. As the elastic linkage member 7 continuously drives the pressing guide member 5, and with the mutual cooperation of the two, the wire rope 4 is dynamically compressed and guided, so that the tightening pressure applied by the pressing guide member 5 on the wire rope 4 is continuously enhanced, further improving the stability of the movement of the wire rope 4 between the bracket 23, the traction frame 22 and the alarm mechanism 3, and preventing the wire rope 4 from shaking and deflecting when running on a fixed track when it is pressed down by the force.

[0055] When the force of the obstacle is lost, the internal elastic component of the elastic linkage 7 can realize its own rapid rebound and reset, which can drive the elastic contact member 6 to quickly reset, so that the wire rope 4 moves upward and the auxiliary wire rope 4 is straightened again. At the same time, the internal elastic component of the micro-trigger assembly 8 can realize its own rapid reset when the resistance force of the elastic linkage 7 is lost, and when the elastic linkage 7 is reset, the drive to the pressing guide 5 can be released, so that the internal component of the pressing guide 5 is reset, and then the synchronous reset of each component is achieved through the reset of the elastic linkage 7.

[0056] Reference Figure 7 and Figure 8The spring 73 is fixed on the driving rod 72, and the spring 74 is provided on the driving rod 72. The spring 74 is located between the pressure plate 73 and the inner bottom side of the sleeve 71. The top of the driving rod 72 is fixedly connected to the elastic contact member 6, and the bottom end of the driving rod 72 contacts the micro-trigger assembly 8. Here, the driving rod 72 is connected to the mounting bracket 21, and the bottom end of the driving rod 72 is in an arc shape, which can reduce the impact of the driving rod 72 on the micro-trigger assembly To prevent scratches caused by the collision of parts 8, guide boxes 75 are fixedly connected to the two brackets 23 respectively, and a pull plate 77 is slidably connected between the two guide boxes 75. The inside of the guide box 75 is fixedly connected with a spring four 76, and the top of the spring four 76 is fixedly connected to the pull plate 77. The top of the pull plate 77 is fixedly connected with a drive rope 78, and the drive rope 78 is transmission-connected to the tightening guide 5. The pull plate 77 is made of aluminum alloy plate, which has strong wear resistance and corrosion resistance, is suitable for external scenes, and has a long service life. The material is light and can be easily rebounded and reset by the elastic action of the spring four 76.

[0057] When the elastic contact piece 6 exerts a force on the elastic linkage piece 7, the driving rod 72 moves downward, so that the bottom end of the driving rod 72 drives the micro-trigger assembly 8 to resist, and when the driving rod 72 moves, it can drive the pressure plate 73 to squeeze the spring three 74. Under the elastic action of the spring three 74, the force applied by the obstacle can be buffered, thereby buffering the instantaneous impact force on the wire rope 4. When the elastic contact piece 6 moves downward, the pull plate 77 can be pressed down synchronously, so that the pull plate 77 drives the driving rope 78 to pull the clamping guide 5, thereby realizing the driving of the clamping guide 5, causing the clamping guide 5 to stretch, thereby driving the clamping guide 5.

[0058] When the force exerted by the obstacle is lost, at this time, the pressure plate 73 can be pushed up by the elastic action of spring three 74, and then the drive rod 72 can be reset, thereby resetting the elastic contact member 6. At the same time, the pull plate 77 can be pushed up by the elastic action of spring four 76, and the pull plate 77 can be reset, thereby assisting the recovery of the drive rope 78.

[0059] Reference Figure 7The elastic contact member 6 includes a sleeve rod 61 fixedly connected to the top of the driving rod 72, and a spring 2 63 is fixedly connected to one side of the inner side of the sleeve rod 61. One end of the spring 2 63 is fixedly connected to the inner rod 62. The inner rod 62 is slidably installed inside the sleeve rod 61. The end of the inner rod 62 away from the sleeve rod 61 is rotatably connected to the contact roller 65, and the top of the inner rod 62 is fixedly connected to the dial ring 64. The wire rope 4 passes through the inner side of the dial ring 64. Here, the contact roller 65 is arranged on one side of the wire rope 4 and close to the wall. When in use, the contact roller 65 is in contact with the wall, and the wire rope 4 passes through the dial ring 64. When the inner rod 62 moves downward, the wire rope 4 is pulled downward through the dial ring 64.

[0060] Under the elastic action of spring 2 63, the inner rod 62 can be pushed up, so that the inner rod 62 drives the contact roller 65 to move toward the wall, and then drives the contact roller 65 to contact the wall, so as to realize the elastic contact member 6 to elastically contact the wall. When the contact roller 65 touches the obstacle, the inner rod 62 and the sleeve rod 61 can be driven downward by the force, and then the driving rod 72 is pressed down by the sleeve rod 61 to drive the elastic linkage member 7. When the inner rod 62 moves downward, it synchronously drives the pull plate 77, so that the pull plate 77 moves downward, and then drives the pressing guide 5. When the inner rod 62 moves downward, it can synchronously drive the dial ring 64 to pull the wire rope 4, so that the wire rope 4 pulls the alarm mechanism 3.

[0061] Reference Figure 9 The micro-trigger assembly 8 includes a connecting seat 81 fixedly connected to one side of the mounting bracket 21, and a micro-switch 86 is fixedly connected to the top of the connecting seat 81. The inner side of the connecting seat 81 is fixedly connected to a telescopic rod 82, and a tension spring 83 is sleeved on the telescopic rod 82. The bottom of the telescopic rod 82 is fixedly connected to a touch member. The touch member includes a force-bearing plate 84 fixedly connected to the bottom end of the telescopic rod 82, and one end of the force-bearing plate 84 is fixedly connected to an L-shaped resistance plate 85. The end of the force-bearing plate 84 away from the L-shaped resistance plate 85 resists the driving rod 72, and the top side of the L-shaped resistance plate 85 corresponds to the micro-switch 86. Here, a plurality of warning lights corresponding to the micro-switches 86 are provided inside the elevator body 1. When the L-shaped resistance plate 85 touches the micro-switch 86 to turn on, the micro-switch 86 can turn on the corresponding warning light, and the size and position of the obstacle can be roughly inferred according to the number and sequence of triggering.

[0062] When the driving rod 72 moves downward, it can resist and drive the force-bearing plate 84, thereby driving the force-bearing plate 84 to move downward, and then driving the L-shaped resistance plate 85 to move downward, so that one end of the L-shaped resistance plate 85 resists and drives the microswitch 86, and then triggers the microswitch 86, so that the microswitch 86 turns on the corresponding warning light inside the elevator body 1. The staff can judge the size and position of the obstacle according to the number and sequence of the triggered warning lights. A single warning light is triggered to prompt a small obstacle. Multiple warning lights are triggered in sequence to infer the distribution length of the obstacle along the running direction of the elevator body 1, so as to roughly detect the size and position of the obstacle.

[0063] When the driving rod 72 cancels the resistance drive on the force-bearing plate 84, the force-bearing plate 84 can be pulled under the elastic action of the tension spring 83, thereby resetting the L-shaped resistance plate 85, so that the L-shaped resistance plate 85 is out of contact with the micro switch 86, and then the warning light is turned off.

[0064] Reference Figures 10 to 13The pressing guide 5 includes a mounting plate 51 fixedly connected to a side bracket 23, one side of the mounting plate 51 is fixedly connected to a limiting plate 52, one side of the limiting plate 52 is rotatably connected to a wire drum 54, and a driving member 55 is installed at the axis of one side of the limiting plate 52, the inner side of the wire drum 54 is fixedly connected to a plurality of elastic pressure members 56, the driving member 55 and the elastic pressure member 56 conflict with each other, and one side of the mounting plate 51 is rotatably connected to a wire drum 53, the wire drum 54 and the wire drum 53 correspond to each other, here, a guide channel for guiding and limiting the movement of the wire rope 4 is formed between the wire drum 54 and the wire drum 53, so that the wire rope 4 will not deviate or slide when sliding inside the guide channel When the cam 55 is pulled off, the driving member 55 includes a threaded rod 551 which is rotatably connected to the limit plate 52. A guide rod 552 is fixedly connected to one side of the limit plate 52. An extrusion block 553 is threadedly connected to the threaded rod 551. One end of the threaded rod 551 is fixedly connected to a winding drum 554. The guide rod 552 and the extrusion block 553 are connected through. One end of the driving rope 78 is wound around the winding drum 554. A reset bearing 555 is installed on one side of the mounting plate 51. The reset bearing 555 is fixedly connected to the threaded rod 551. The extrusion block 553 and the elastic pressure piece 56 conflict with each other. Here, a reset coil spring is provided inside the reset bearing 555. When the driving rope 78 stops pulling the winding drum 554, When the screw rod 551 is rotated, the reset bearing 555 can drive the screw rod 551 to rotate, driving the extrusion block 553 away from the elastic pressure piece 56, so that multiple elastic pressure pieces 56 can be reset. The extrusion block 553 is conical, and the elastic pressure piece 56 can be pushed up by the movement of the extrusion block 553, so that the elastic pressure piece 56 can be extended. In addition, the surface of the extrusion block 553 is smoothed to reduce the friction between the extrusion block 553 and the elastic pressure piece 56, thereby improving the smoothness of the friction drive between the extrusion block 553 and the elastic pressure piece 56. The elastic pressure piece 56 includes a connecting tube 561 fixedly connected to the inner side of the rolling drum 54, and the inner side of the connecting tube 561 is slidably connected to the contact block 562. One end of block 562 contacts with the extrusion block 553, and the other end of the contact block 562 is fixedly connected to a connecting rod 563, one end of the connecting rod 563 is fixedly connected to a rubber pressure block 565, and a spring 564 is provided on the outer side of the connecting rod 563. Here, the rubber pressure block 565 is made of rubber material and has strong elasticity, which can increase the friction between it and the wire rope 4, and at the same time enhance the pressing strength of the wire rope 4 and improve the stability of the wire rope 4 when moving. The end of the contact block 562 close to the extrusion block 553 is an inclined structure, corresponding to the extrusion block 553, and one end of the contact block 562 is not the only structure, and a roller can also be set to contact the extrusion block 553.

[0065] The guide channel for guiding and limiting the movement of the wire rope 4 is formed between the wire roller 54 and the wire drum 53. The wire rope 4 can be limited and guided by the guide channel so that it will not deviate or fall off when sliding. When the pull plate 77 pulls the driving rope 78, the driving rope 78 pulls the winding drum 554, so that the winding drum 554 drives the threaded rod 551 to rotate. The rotating threaded rod 551 can drive the extrusion block 553 to move toward the direction of the interference block 562, thereby contacting the multiple interference blocks 562. 62 is driven, so that the resistance block 562 drives the connecting rod 563 to move, and then drives the rubber pressure block 565 to extend from the inside of the roller drum 54, so that the rubber pressure block 565 can squeeze the wire rope 4, and cooperate with the wire drum 53 to press and guide the wire rope 4 for transportation, to prevent the wire rope 4 from shaking and deflecting when running on a fixed track when it is pressed down by the force, so that the wire rope 4 can stably pull the alarm mechanism 3 to avoid false triggering or missed detection, thereby further improving the accuracy and stability of the early warning.

[0066] Working principle: When the lift body 1 is lifted and lowered, the upper and lower connecting frames 2 of the lift body 1 are driven to move, and then the wire rope 4 and the alarm mechanism 3 are driven to move along with the lifting and lowering of the lift body 1. During this period, the inner rod 62 can be placed on top by the elastic action of the spring 2 63, so that the inner rod 62 drives the contact roller 65 to move toward the wall, and then drives the contact roller 65 to contact the wall, thereby realizing the elastic contact member 6 to elastically contact the wall. When there is something on the wall, When there is an obstacle, when the contact roller 65 touches the obstacle, the inner rod 62 and the sleeve rod 61 can be driven by the force to move downward, and then the sleeve rod 61 presses the driving rod 72 downward to drive the elastic linkage 7, and when the inner rod 62 moves downward, it drives the pull plate 77 synchronously, so that the pull plate 77 moves downward, and then drives the pressing guide 5. When the inner rod 62 moves downward, it can synchronously drive the dial ring 64 to pull the wire rope 4, so that the wire rope 4 moves along the bracket 23 and the side. The traction frame 22 moves and pulls the alarm mechanism 3, thereby causing one end of the wire rope 4 to pull the counterweight 32, causing the counterweight 32 to move upward, and then to resist the touch sensing block 34, causing the touch sensing block 34 to send a signal to the alarm 35. After receiving the signal, the alarm 35 can sound an alarm to warn the surrounding staff and send an alarm signal to the remote terminal so that the staff can deal with the elevator body 1 in time, thereby realizing obstacle detection and early warning, thereby improving the safety of the elevator operation. When the internal components of the elastic contact member 6 are in contact with the wall, it is convenient to detect small obstacles extending from the wall, thereby improving the accuracy of detection. During the period when the wire rope 4 pulls the counterweight 32, the wire rope 4 is limited and guided by the compression guide member 5, thereby avoiding unnecessary wear of the wire rope 4 when it moves, reducing the wear of the wire rope 4 during the pulling work, maximizing the service life of the wire rope 4, and reducing the replacement frequency of the wire rope 4.

[0067] When the corresponding elastic contact member 6 contacts the obstacle and moves downward, it can drive the elastic linkage member 7 to operate, so that the internal components of the elastic linkage member 7 drive the micro-trigger assembly 8, so that the internal components of the micro-trigger assembly 8 extend, and then drive the micro-switch 86 inside the micro-trigger assembly 8, and the micro-switch 86 can be touched and started to turn on the corresponding warning light inside the elevator body 1. The staff can judge the size and position of the obstacle according to the number and sequence of the triggered warning lights. A single warning light is triggered to prompt a small obstacle. Multiple warning lights are triggered in sequence to infer the distribution length of the obstacle along the running direction of the elevator body 1. In this way, the size and position of the obstacle can be roughly detected, which can be combined with the touch detection of the wire rope 4 to provide a more accurate warning of the obstacle, maximize the accuracy of the warning, and thus improve the safety of the elevator.

[0068] While the elastic contact member 6 drives the elastic linkage member 7 to press down and drive the micro-trigger assembly 8, the elastic linkage member 7 can simultaneously drive the pressing guide member 5, so that the internal components of the pressing guide member 5 are in operation and the internal components are stretched. As the elastic linkage member 7 continuously drives the pressing guide member 5, and with the mutual cooperation of the two, the wire rope 4 is dynamically compressed and guided, so that the tightening pressure applied by the pressing guide member 5 on the wire rope 4 is continuously enhanced, further improving the stability of the movement of the wire rope 4 between the bracket 23, the traction frame 22 and the alarm mechanism 3, and preventing the wire rope 4 from shaking and deflecting when running on a fixed track when it is pressed down by the force.

[0069] When the force of the obstacle is lost, the spring three 74 can be used to quickly rebound and reset itself, which can drive the contact roller 65 to quickly reset, so that the wire rope 4 moves upward and the auxiliary wire rope 4 is straightened again. At the same time, the internal elastic component of the micro-trigger assembly 8 can quickly reset itself when the resistance force of the elastic linkage 7 is lost. When the elastic linkage 7 is reset, the drive to the pressing guide 5 can be released, so that the internal components of the pressing guide 5 are reset, and then the synchronous reset of each component is achieved through the reset of the elastic linkage 7.
