Description

Technical Field

[0001] The utility model relates to the technical field of safety rope detection, in particular to a daily safety rope detection device. Background Art

[0002] Safety ropes are used in many fields, such as mountain climbing, cleaning building exterior walls, etc. There are many places where installation ropes are used, and safety ropes are reusable. However, the performance of safety ropes will decrease with the increase in the number of uses. Therefore, in order to ensure the effectiveness of the safety rope, the safety rope needs to be tested regularly.

[0003] At present, most of the methods for testing safety ropes are to test the tension of the safety rope. One end of the safety rope is tied to an object and the other end is tied to a lifting device. The lifting device moves upward and the safety rope is pulled upward. As the lifting device continues to move upward, the tension on the safety rope increases, so that the safety rope can be tested.

[0004] Although the above method can detect the tension of the safety rope, in actual use, a person or object tied to one end of the safety rope may fall freely when the equipment is operated incorrectly. The free fall movement will increase the tension on the safety rope. When the person or object reaches the lowest point, the tension on the safety rope is the largest in a short time. At the same time, the person or object will move upward under the toughness of the elastic rope. Therefore, when testing the safety rope, the bearing capacity of the safety rope in a short time must also be tested to ensure that the safety rope can be used safely. Therefore, we propose a daily safety rope detection device to solve the above problem. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 4The utility model provides a technical solution: a daily detection device for a safety rope, comprising a base plate 1 and a detection mechanism 3. The upper surface of the base plate 1 is fixedly connected to a rectangular frame 2. The detection mechanism 3 comprises a rectangular plate 31. The rectangular plate 31 is installed at the inner position of the rectangular frame 2. A dynamometer 311 is fixedly installed at the bottom of the rectangular plate 31. A weight block 32 is arranged at the inner position of the rectangular frame 2. A connecting ring 321 is fixedly connected to the top of the weight block 32. A limiting hole 331 is provided on the side of the weight block 32. A positioning pin 33 is slidably installed inside the limiting hole 331.

[0028] In a preferred embodiment, the upper surface of the base plate 1 is fixedly connected to the display 4, which is electrically connected to the force gauge 311. The upper surface of the base plate 1 is fixedly installed with reinforcing ribs 5, which are fixedly connected to the rectangular frame 2. In order to facilitate the observation of the tension during the safety test, a display 4 is installed on the base plate 1, and the display 4 is electrically connected to the force gauge 311. The force gauge 311 is fixedly installed at the bottom of the rectangular plate 31. Each time the safety rope is tested, the safety rope must be tied to the force gauge 311. By pulling the safety rope through the force gauge 311, the tension on the safety rope can be measured.

[0029] In a preferred embodiment, a plurality of through holes 6 are provided on the outer surface of the rectangular frame 2 and are evenly arranged on the outer surface of the rectangular frame 2. The positioning pins 33 are inserted into the interior of the through holes 6. The device can detect the safety rope in two situations. One is to make a free fall through the weight block 32 to detect the instantaneous bearing force of the safety rope. The other is to position the weight block 32 and pull the weight block 32 upward through the safety rope to detect the tension of the safety rope. Multiple tests can ensure that the safety rope can be used safely.

[0030] In a preferred embodiment, the upper surface of the base plate 1 is fixedly connected to the servo motor 7, the output end of the servo motor 7 is fixedly installed with a screw rod 8, the screw rod 8 is threadedly connected to a nut, and a movable plate 9 is fixedly installed on the outside of the nut. The upper surface of the movable plate 9 is rotatably connected to a support rod 10, one end of the support rod 10 is rotatably connected to a load-bearing plate 11, the bottom of the load-bearing plate 11 is rotatably connected to a connecting rod 12, and the bottom of the connecting rod 12 is rotatably connected to a sliding block 13.

[0031] After the weight block 32 moves in free fall, the weight block 32 will be at the bottom end of the inner side of the rectangular frame 2. Since the weight block 32 is heavy, it is difficult for the staff to restore it to its original position alone. Therefore, a servo motor 7 is installed on the bottom plate 1. The servo motor 7 drives the screw rod 8 to rotate, which can control the movement of the moving plate 9 and also drive the sliding block 13 to move, so as to control the load-bearing plate 11 to move upward and push the weight block 32 to move upward, thereby moving the weight block 32 to the initial position.

[0032] In addition to using the weight block 32 to perform free fall motion to detect the tension of the safety rope, the device can also detect the tension of the safety rope when the safety rope is pulled upward to ensure that the safety rope can be used safely. Therefore, a pulling mechanism 14 is installed on the rectangular frame 2. The pulling mechanism 14 includes a cylinder 141, a limit plate 142 and a pull rod 143. The cylinder 141 is fixedly installed on the top of the rectangular frame 2. The telescopic end of the cylinder 141 is fixedly connected to the pull rod 143. One end of the pull rod 143 is fixedly connected to the rectangular plate 31. The outer side surface of the rectangular plate 31 is fixedly connected to the limit plate 142. The limit plate 142 is slidably connected to the inner side surface of the rectangular frame 2. The bottom of the rectangular frame 2 is set to be open.

[0033] During operation, the weight block 32 is first positioned after free fall, and the positioning pin 33 is inserted into the inside of the weight block 32 to position the weight block 32. Then the telescopic end of the cylinder 141 is controlled to retract. At this time, the rectangular plate 31 will be driven to move upward, while the weight block 32 cannot move upward. As the rectangular plate 31 is continuously pulled, the tension on the safety rope becomes greater and greater, thereby detecting the tension of the safety rope to ensure that the safety rope can be used normally.

[0034] Specifically, the working process or working principle of a daily safety rope detection device is as follows: Currently, the method of detecting safety ropes is mostly to detect the tension of the safety rope, by tying one end of the safety rope to an object and the other end to a lifting device, and then moving the lifting device upward to pull the safety rope upward. As the lifting device continues to move upward, the tension on the safety rope will increase, so that the safety rope can be detected.

[0035] Although the above method can detect the tension of the safety rope, in actual use, a person or object tied to one end of the safety rope may perform free fall when the equipment is operated incorrectly. The free fall movement will increase the tension on the safety rope. When the person or object reaches the lowest point, the tension on the safety rope is the largest in a short time. At the same time, the person or object will move upward under the toughness of the elastic rope. Therefore, when testing the safety rope, the bearing capacity of the safety rope in a short time must also be tested to ensure that the safety rope can be used safely. Therefore, this device is designed to solve this problem.

[0036] The device is used to regularly check the safety rope to ensure that the safety rope can be used normally. The cylinder 141 and the dynamometer 311 are connected to an external power supply for use. One end of the safety rope to be tested is tied to the dynamometer 311, and the other end is tied to the weight block 32. The weight block 32 is equipped with a connecting ring 321 for tying the safety rope thereon. Initially, the weight block 32 is set at the upper end of the rectangular frame 2, and the weight block 32 is positioned by the positioning pin 33. After the safety rope is tied, the positioning pin 33 can be pulled out from the inside of the weight block 32. At this time, the weight block 32 will fall rapidly under the action of its own gravity and move in free fall. The free fall motion will have acceleration, which will make the weight block 32 exert a force on the safety rope when it reaches the lowest point. The force exerted on the safety rope when the weight block 32 is stable is greater than the force exerted on the safety rope by the weight block 32. This requires the safety rope to be able to withstand the instantaneous strong pulling force exerted on the safety rope by the weight block 32, otherwise the safety rope will be broken.

[0037] Such detection is to avoid accidents when using the safety rope. No matter whether the end of the safety rope is tied to a person or an object, it must be tied stably to ensure safety.

[0038] When the weight block 32 falls rapidly to the lowest point, the elastic potential energy will cause the weight block 32 to bounce upwards, and then fall again, and repeat this process until the weight block 32 gradually tends to be stable. During this process, the instantaneous tension of the safety rope and the toughness of the safety rope can be tested. The force gauge 311 can be used to test the instantaneous tension of the safety rope and observe how much force the safety rope can withstand. After the safety rope is stable, the outer surface of the safety rope should also be observed to prevent breakage that would affect its use.

[0039] When the weight block 32 is in a stable state, the positioning pin 33 can be inserted into the inside of the weight block 32 again to limit the weight block 32, and then the telescopic end of the cylinder 141 is retracted, driving the rectangular plate 31 to move upward, pulling the safety rope, and pulling the weight block 32, so that the tension of the safety rope can be gradually tested, and the tension can be detected by the force gauge 311.

[0040] Through the above two methods, the safety rope is tested in different states to ensure that the safety rope can be used normally to protect the safety of the staff.

[0041] After the detection is completed, in order to facilitate subsequent detection, the weight block 32 can be moved to the initial position. At this time, the servo motor 7 drives the screw rod 8 to rotate, and the movement of the control nut will drive the support rod 10 to rotate upward. At the same time, the connecting rod 12 will also rotate, which will move the load-bearing plate 11 upward and push the weight block 32 upward. Push the weight block 32 to the initial position, and then use the positioning pin 33 to insert it into the inside of the weight block 32 to position the weight block 32 so that it can be used directly later.
