Technical Field
[0001] The utility model relates to the technical field of safety rope detection, in particular to a device for detecting the strength of a safety rope for high-altitude work. Background Technique
[0002] A safety rope is an auxiliary tool for connecting a safety belt, usually used at high altitudes, such as in scenarios of high-altitude work, high-altitude rescue, rock climbing, mountain climbing, etc. It is mainly used to provide a safety protection function to prevent people from falling from high altitudes. After the safety rope is produced, it needs to be subjected to strength quality inspection, or it also needs to be inspected after being used for a period of time to avoid safety accidents caused by fracture when used at high altitudes.
[0003] Existing safety rope strength detection devices usually fix one end of the safety rope and then apply a pulling force to the other end of the safety rope to detect the strength of the safety rope. However, the lengths of safety ropes vary. If a long safety rope is detected, it will cause the detection equipment to be too large in volume, and the area that needs to be protected will also increase, thereby increasing costs. Otherwise, when the safety rope breaks, it is easy to swing out and injure the surrounding staff. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a device for detecting the strength of a safety rope for high-altitude work to solve the technical problems mentioned in the above background technique.

A motor is installed inside the device main body, and the output end of the motor is connected to a speed reducer. The output end of the speed reducer is connected to a cover plate through a transmission shaft. A guide groove is opened on one side of the top of the cover plate, and a slider penetrates through the bottom of the guide groove. A guide frame is fixed on the top of the device main body.
[0006] By adopting the above technical solution, the hooks on the safety rope are respectively hung on two hanging rings, and then the motor is turned on. After the motor starts, the output end drives the cover plate to rotate through the speed reducer and the transmission shaft. When the cover plate rotates, it drives the slider to revolve. During the revolution of the slider, it is guided by the guide frame, so that the slider slides on the guide groove towards the center of the cover plate. At the same time, the slider and the hook at the bottom of the slider tighten the safety rope, so as to facilitate the detection of the strength of the safety rope. Since the guide frame is spiral, the safety rope is pulled into a spiral shape, and a longer safety rope can be detected in a smaller space. Moreover, the cover plate can play a protective role to prevent the safety rope from breaking and flying out to injure the surrounding staff.
[0007] Further, the guide frame is spiral.

[0010] By adopting the above technical solution, during the revolution of the slider, it is guided by the guide frame, so that the slider slides on the guide groove towards the center of the cover plate. At the same time, the slider and the hook at the bottom of the slider tighten the safety rope.
[0011] Further, the cover plate is rotatably connected to the guide frame.
[0012] By adopting the above technical solution, the staff turns on the motor. After the motor starts, the output end drives the cover plate to rotate through the reducer and the transmission shaft. After the cover plate rotates, it drives the slider to revolve.
[0013] Further, a tension sensor is installed on one side of the top of the device body, and hanging rings are fixed on the back of the tension sensor and the bottom of the slider.
[0014] By adopting the above technical solution, the slider and the hook at the bottom of the slider tighten the safety rope, and the tension sensor detects the tension to facilitate recording information for detecting the strength of the safety rope.
[0015] Further, a bolt penetrates through the top of the cover plate, a plug rod is fixed in the middle of the bottom of the cover plate, and a slot is opened in the middle of the top of the transmission shaft.
[0016] By adopting the above technical solution, when the cover plate is damaged or the debris of the safety rope inside the guide frame needs to be cleaned, the staff removes the bolt, and then the cover plate can be directly removed. After cleaning or preparing a new cover plate, the staff first aligns the plug rod with the slot and then places the cover plate on the transmission shaft. Then the staff tightens the bolt to limit the position of the cover plate. The bolt and the plug rod synchronously transmit torque to facilitate the transmission shaft to drive the cover plate to rotate.
[0017] Further, the bolt is threadedly connected to the transmission shaft, and the cover plate is detachably connected to the transmission shaft through the bolt.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0029] Next, the embodiments of the present utility model will be described according to its overall structure.
[0030] Embodiment 1:
[0031] A safety rope strength detection device for high-altitude work, such as Figures 1-4As shown in the figure, it includes a device main body 1. Inside the device main body 1, a motor 4 is installed. The output end of the motor 4 is connected to a speed reducer 5. The output end of the speed reducer 5 is connected to a cover plate 7 through a transmission shaft 6. The cover plate 7 is rotatably connected to a guide frame 3. After the motor 4 is started, the output end drives the cover plate 7 to rotate through the speed reducer 5 and the transmission shaft 6. On one side of the top of the cover plate 7, a guide groove 8 is opened. The bottom of the guide groove 8 penetrates through a slider 9. The slider 9 is slidably connected to the guide groove 8. The top of the device main body 1 is fixed with a guide frame 3. The slider 9 is slidably connected to the guide frame 3. The guide frame 3 is spiral. During the revolution of the slider 9, it is guided by the guide frame 3, so that the slider 9 slides on the guide groove 8 towards the center of the cover plate 7. At the same time, the slider 9 and the hook at the bottom of the slider 9 tighten the safety rope, so as to facilitate the detection of the strength of the safety rope. Since the guide frame 3 is spiral, the safety rope is pulled into a spiral shape, and a longer safety rope can be detected in a smaller space.
[0032] Refer to Figures 1-4 , in the above embodiment, a tension sensor 2 is installed on one side of the top of the device main body 1. Hanging rings 10 are fixed on the back of the tension sensor 2 and the bottom of the slider 9. The tension is detected by the tension sensor 2 to facilitate recording information.
[0033] Embodiment Two:
[0034] On the basis of the above Embodiment One, in order to facilitate the replacement of the damaged cover plate 7 and the cleaning of the safety rope debris in the guide frame 3, the following settings are made now.
[0035] Refer to Figures 1-4 , in the above embodiment, a bolt 11 penetrates through the top of the cover plate 7. The bolt 11 is threadedly connected to the transmission shaft 6. The cover plate 7 is detachably connected to the transmission shaft 6 through the bolt 11. When the cover plate 7 is damaged or the safety rope debris inside the guide frame 3 needs to be cleaned, the staff removes the bolt 11, and then the cover plate 7 can be directly removed. In the middle of the bottom of the cover plate 7, a plug rod 13 is fixed. In the middle of the top of the transmission shaft 6, a slot 12 is opened. Both the slot 12 and the plug rod 13 are in a cross shape. The plug rod 13 is adapted to the slot 12. The staff first aligns the plug rod 13 with the slot 12 and then places the cover plate 7 on the transmission shaft 6. Then the staff tightens the bolt 11 to limit the cover plate 7. The torque is transmitted synchronously through the bolt 11 and the plug rod 13, so as to facilitate the transmission shaft 6 to drive the cover plate 7 to rotate.
[0036] The implementation principle of the present utility model is as follows: First, the staff hang the hooks on the safety rope on the two hanging rings 10 respectively. Then, the staff start the motor 4. After the motor 4 starts, the output end drives the cover plate 7 to rotate through the reducer 5 and the transmission shaft 6. After the cover plate 7 rotates, it drives the slider 9 to revolve. During the revolution of the slider 9, it is guided by the guide frame 3, so that the slider 9 slides on the guide groove 8 towards the center of the cover plate 7. At the same time, the slider 9 and the hook at the bottom of the slider 9 tighten the safety rope, so as to facilitate the detection of the strength of the safety rope. Since the guide frame 3 is spiral, the safety rope is pulled into a spiral shape, and a longer safety rope can be detected in a smaller space. Moreover, the cover plate 7 can play a protective role to prevent the safety rope from flying off and injuring the surrounding staff after breaking. At the same time, the tension sensor 2 is used to detect the tension to facilitate recording information. After the detection is completed, the staff control the output end of the motor 4 to reverse, so that the cover plate 7 reverses, and then the slider 9 and the hanging ring 10 at the bottom of the slider 9 move in the reverse direction and move out of the guide frame 3. Then, the staff can remove the safety rope.
[0037] When the cover plate 7 is damaged or it is necessary to clean the debris of the safety rope inside the guide frame 3, the staff remove the bolt 11, and then can directly remove the cover plate 7. After cleaning or preparing a new cover plate 7, the staff first align the insertion rod 13 with the insertion slot 12 and then place the cover plate 7 on the transmission shaft 6. Then, the staff tighten the bolt 11 to limit the cover plate 7. The bolt 11 and the insertion rod 13 synchronously transmit torque, so as to facilitate the transmission shaft 6 to drive the cover plate 7 to rotate.
