Description

Technical Field

[0001] The utility model relates to the field of high-altitude operations technology, specifically to a quick-adjustment device for the safety suspension wheel of a fall prevention lifeline. Background Technology

[0002] A fall protection lifeline for working at heights is an important safety device used to protect personnel working at heights from fall injuries. It typically includes a series of components such as steel cables, ropes, track lifelines, and safety suspension wheels connected to the worker's safety belt; and lifelines generally include steel cable lifelines, track-type lifelines, and flexible lifelines.

[0003] In high-altitude work fall protection lifeline systems, after workers complete their work, the safety suspension wheels are usually scattered across the track, resulting in low efficiency in returning the safety suspension wheels to their original positions. Existing return systems mostly rely on mechanical push rods and wheel drives, which suffer from problems such as high friction loss, unstable movement, and strong energy dependence. Furthermore, pushing multiple safety suspension wheels to their original positions can cause collisions between the wheels, leading to damage to the safety suspension wheels.

[0004] Therefore, we propose a device that can improve the return efficiency and prevent damage to the safety suspension wheel. Utility Model Content

[0005] The purpose of this invention is to provide a quick-alignment device for the safety suspension wheel of a fall prevention lifeline, which solves the problem of low alignment efficiency in traditional alignment systems.

[0006] This utility model is achieved through the following technical solution:

[0007] A quick-adjustment device for a safety suspension plate wheel of a fall protection lifeline includes a moving body, a first limit switch, and a second limit switch;

[0008] The first limit switch is located at the head end of the track lifeline, the second limit switch is located at the tail end of the track lifeline, and multiple safety suspension wheel plates are placed between the second limit switch and the tail end of the track lifeline.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] like Figures 1-3 The safety suspension plate wheel quick-adjustment device for a fall protection lifeline shown includes a moving body 3, a first limit switch 1, and a second limit switch 2;

[0029] The first limit switch 1 is located at the head end of the track lifeline 7, the second limit switch 2 is located at the tail end of the track lifeline 7, and multiple safety suspension wheel 8 are placed between the second limit switch 2 and the tail end of the track lifeline 7.

[0030] The starting position of the main body 3 is at the first limit switch 1, and the starting position of all safety suspension wheels 8 is between the second limit switch 2 and the end of the track lifeline 7. When the staff needs to perform related work along the track lifeline 7, they will connect the safety buckle to the safety suspension wheels 8. After the work is completed, the safety suspension wheels 8 may be dispersed between the main body 3 and the second limit switch 2. At this time, the staff on the ground presses the forward button on the remote control 6. When the control unit 5 receives the forward signal from the remote control 6, it controls the main body 3 to move towards the end of the track lifeline 7. During the movement of the main body 3, the safety suspension wheels 8 are gradually moved towards the end of the track lifeline 7, thus realizing the return of the safety suspension wheels 8. When the main body 3 moves to the second limit switch 2, the control unit 5 will receive the arrival signal sent by the second limit switch 2, and the control unit 5 will stop the main body 3 from working, so that the main body 3 stops at the second limit switch 2.

[0031] The moving body 3 is used to move along the length of the track lifeline 7. That is, when the moving body 3 moves from the head end to the tail end of the track lifeline 7, the tail end of the moving body 3 can push the safety suspension wheels 8 to move towards the tail end of the track lifeline 7 in sequence until the tail end face of the moving body 3 contacts the second limit switch 2. At this time, multiple safety suspension wheels 8 are also pushed between the second limit switch 2 and the tail end of the track lifeline 7, realizing the centralized placement of the safety suspension wheels 8. At this time, it is more convenient for the staff to inspect all the safety suspension wheels 8 or to retrieve the safety suspension wheels 8 during the next construction.

[0032] A repositioning unit 4 is fixedly installed at the tail end of the main body 3. The repositioning unit 4 includes a base 41, and multiple anti-collision blocks 42 are fixedly arranged on the top surface of the base 41. The multiple anti-collision blocks 42 are evenly distributed along the length direction of the base 41. A safety suspension wheel 8 is placed between two adjacent anti-collision blocks 42 to prevent the safety suspension wheels 8 from colliding with each other during the repositioning process, thereby effectively avoiding damage to the safety suspension wheels 8. The side of the base 41 is equipped with clamps for holding the safety suspension wheels 8 and driving the safety suspension wheels 8 along the base 41. The positioning mechanism 43 moves along the length direction. During the repositioning operation, the positioning mechanism 43 first clamps a safety suspension wheel 8. Then, the moving body 3 stops, and the positioning mechanism 43 moves towards the head end of the track lifeline 7 until the clamped safety suspension wheel 8 moves between the first anti-collision block 42 and the base 41. At this time, the positioning mechanism 43 will release the clamping state from the safety suspension wheel 8. Then, the moving body 3 continues to move to perform the repositioning operation, and the next safety suspension wheel 8 will be repositioned between the first anti-collision block 42 and the second anti-collision block 42.

[0033] It should be noted that after all the safety suspension wheels 8 have been put back into place, when the main body 3 needs to return to the first limit switch 1, the positioning mechanism 43 first clamps the safety suspension wheel 8 closest to the second limit switch 2, and then the main body 3 moves towards the head end of the track lifeline 7. At this time, the positioning mechanism 43 is stationary in space, but relative to the base 41, the positioning mechanism 43 is moving towards the tail end of the track lifeline 7 until the safety suspension wheels 8 are disengaged from all the anti-collision blocks 42. Then the clamping state between the positioning mechanism 43 and the safety suspension wheels 8 is released, and the main body can then return to the first limit switch 1.

[0034] In addition, the anti-collision block 42 is generally made of silicone, which has a certain deformation capacity and can also act as a buffer block between the two safety suspension plate wheels 8.

[0035] As needed, the positioning mechanism 43 includes a linear guide rail 431, which is mounted on the side of the base 41. An extension rod 433 is fixedly mounted on the drive part of the linear guide rail 431, and an electromagnet 434 for adsorbing the safety suspension wheel 8 is fixedly mounted at the head of the extension rod 433. Both the linear guide rail 431 and the electromagnet 434 are electrically connected to the output pin of the control unit 5. It should be noted that the drive part on the linear guide rail 431 is a linear motor 313, which can move along the linear guide rail 431, thereby driving the mounting base 432 to move together.

[0036] The main body 3 is equipped with a control unit 5. The input pins of the control unit 5 are electrically connected to the first limit switch 1 and the second limit switch 2, respectively. The output pins of the control unit 5 are electrically connected to the main body 3 and the positioning mechanism 43, respectively.

[0037] In addition, the control unit 5 includes a built-in power supply 51, a microcontroller 52 and an infrared receiver 53. The built-in power supply 51 supplies power to the motor 313 and the microcontroller 52 respectively. The signal input pins of the microcontroller 52 are electrically connected to the detection unit and the infrared receiver 53 respectively. The control output pins of the microcontroller 52 are electrically connected to the motor 313. The infrared receiver 53 is signal connected to the remote controller 6.

[0038] When the staff operates the remote control 6, the infrared signal emitted by the remote control 6 contains the corresponding control information according to the different buttons pressed on the remote control 6. After the control unit 5 receives the infrared signal, it can perform subsequent control operations, specifically controlling the movement of the main body 3, controlling the movement of the positioning mechanism 43, or performing the action of clamping the safety suspension wheel 8.

[0039] In addition, the microcontroller 52 receives input signals and outputs control commands. Specifically, it receives the corresponding infrared signals sent by the remote controller 6 and the stop signals sent by the first limit switch 1 or the second limit switch 2. The output control commands are as follows: when a forward signal is received from the remote controller 6, the motor 313 in the moving body 3 is controlled to rotate forward, and the moving body 3 moves towards the end of the track lifeline 7. When a backward signal is received, the motor 313 in the moving body 3 is controlled to rotate in reverse, and the moving body 3 moves towards the beginning of the track lifeline 7. When a stop signal is received, the motor 313 in the moving body 3 is controlled to stop, and the moving body 3 is brought to a standstill. When a positioning forward signal is received, the linear guide rail 431 is controlled to move towards the beginning of the track lifeline 7. When a positioning backward signal is received, the linear guide rail 431 is controlled to move towards the end of the track lifeline 7. After receiving a clamping signal, the electromagnet 434 is controlled to be energized. After receiving a clamping release signal, the electromagnet 434 is controlled to be de-energized.

[0040] Specifically, the microcontroller 52 is an STM32F103C8T6 model. This microcontroller 52 is equipped with a variety of peripheral interfaces, including but not limited to USART, SPI, I2C, CAN, USB, etc., which allows it to easily connect to various sensors, including the first limit switch 1, the second limit switch 2, the infrared receiver 53, and the motor 313 of the moving body 3. It has direct memory access (DMA) functionality, which allows data transfer to occur directly between memory and peripherals without going through the CPU, thereby reducing the CPU load and improving the overall system efficiency. It is particularly suitable for applications requiring fast response. It also has multiple general-purpose timers and advanced control timers, supports PWM output, and is very suitable for speed control of the motor 313. In addition, it has a flexible power management mode, which helps to extend the working time of battery-powered devices and is also more energy-efficient and environmentally friendly.

[0041] Example 2

[0042] As one embodiment, the action body 3 includes a return trolley 32, which moves along the length of the track lifeline 7 via a drive unit 31. A control unit 5 is installed inside the return trolley 32, and the tail end of the return trolley 32 is fixedly connected to the return unit 4.

[0043] In addition, the track section 71 of the track lifeline 7 includes a track body 711 and two C-shaped steels 712, wherein the bottom of the track body 711 is fixedly connected to the two C-shaped steels 712, and the openings of the two C-shaped steels 712 correspond to each other and are spaced apart; the lifeline section 72 of the track lifeline 7 passes through the opening space of the two C-shaped steels 712.

[0044] In this structure, the track body 711 serves as a fixed component of the overall track lifeline 7. It is generally fixedly installed on the work platform to provide support for the C-shaped steel 712 and the lifeline section 72. The safety suspension plate wheel 8 is slidably installed on the lifeline section 72 to provide safety protection for workers working at heights. The two C-shaped steels 712 are used for the movement of the driven wheel 312, and the space formed by the openings of the two C-shaped steels 712 can be used for the passage of the lifeline section 72.

[0045] As needed, the drive unit 31 includes a drive wheel 311, a driven wheel 312, and a motor 313. The outer edge of the drive wheel 311 abuts against the track section 71 of the track lifeline 7. The driven wheel 312 is fixedly installed on the top of the retrieval trolley 32 and is slidably connected to the lifeline section 72 of the track lifeline 7. The motor 313 is correspondingly driven by the drive wheel 311. Through the cooperation of the drive wheel 311 and the driven wheel 312, the movement of the retrieval trolley 32 on the track lifeline 7 can be made more stable. The movement of the retrieval trolley 32 is driven by the friction between the drive wheel 311 and the track body 711. The forward and backward movements of the retrieval trolley 32 are determined by the forward and reverse rotation of the motor 313.

[0046] It should be noted that the driven wheel 312 is fixedly installed with the traveling trolley through the mounting plate 3121, and the driven wheel 312 and the track body 711 can move relative to each other.

[0047] In addition, the driven wheel 312 includes a mounting plate 3121, a rotating shaft 3122, and a wheel set 3123. The bottom of the mounting plate 3121 is fixedly connected to the top of the retrieval trolley 32. The top of the mounting plate 3121 is provided with multiple rotating shafts 3122 perpendicular to the plate surface. The mounting plate 3121 is provided with a through hole for the lifeline section 72 to pass through. A wheel set 3123 is rotatably mounted on each of the rotating shafts 3122. The two wheels of the wheel set 3123 are respectively located in two C-shaped steels 712. The wheel set 3123 mainly bears the weight of the entire moving body 3, and the structure of multiple wheel sets 3123 also greatly enhances the load-bearing capacity, ensuring the stability of the moving body 3 when moving.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
