Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety belt anti-falling, in particular to a safety belt anti-falling device for high-altitude operations. Background Art
[0002] Correct use of safety belts is the last line of defense for workers working at heights. According to safety work regulations, workers must not lose the protection of their safety belts when transferring work positions. During actual work (moving equipment at height or going up and down poles), in order to adapt to changes in equipment structure, workers constantly switch between the primary (rail belt) and secondary (safety rope) safety belts to ensure that they do not lose the protection of the safety belts during the operation. Frequent switching operations not only significantly reduce work efficiency and increase labor intensity, but may even cause the safety belt to lose both the primary and secondary belt protection due to momentary negligence of the workers, ultimately leading to a fall from height.
[0003] Currently, by adding a fall arrest device to equipment (or lines), when workers relocate, the secondary (safety rope) safety belt is connected to the fall arrest device, allowing for flexible movement up and down. Workers only need to switch the position of the primary (rail belt) safety belt, eliminating the need for frequent switching to ensure they retain the protection of the safety belt. However, installing a fall arrest device increases costs and requires significant maintenance and safety testing. In light of this, a fall arrest device for a safety belt used in aerial work is proposed. Summary of the Invention
[0004] The technical solution adopted by the utility model to solve its technical problems is: a high-altitude work safety belt anti-fall device, including a traction rope, a guide wheel, a fixing device and a safety rope, the guide wheel is a fixed pulley, which is respectively arranged at the top of the building construction surface and the opposite side thereof, the fixing device includes a first fixing device and a second fixing device, the first fixing device is arranged at the bottom of the building construction surface, and the second fixing device is arranged at the opposite side of the bottom of the building construction surface, one end of the traction rope can be installed on the first fixing device, and the other end can be connected to the second fixing device after passing around the guide wheel;
[0005] The end of the traction rope after being released from the fixing device can be connected to the front end of the safety rope, and the safety rope can be wound around the guide wheel by pulling the traction rope, and the front end of the safety rope can be connected to the second fixing device after the connection end of the traction rope is detached, and the rear end of the safety rope is pulled to keep the entire safety rope in a taut state;
[0006] It also includes a safety rope and a fall arrester connected thereto, wherein the fall arrester is a differential fall arrester, the fall arrester is installed on the safety rope, and the safety rope is connected to a safety belt of the personnel.

[0008] Preferably, a counterweight is mounted on the rear end of the safety rope.
[0009] Preferably, the fixing device is a hook and ring connection structure.
[0010] The beneficial effect of the present invention is that the present invention adopts a tightened safety rope as a safety protection rope on the construction surface, a differential fall arrester is installed on the safety rope, and the fall arrester is connected to the body mounting belt, the fall arrester can slide up and down along the safety rope when the worker moves up and down, and the differential fall arrester can hold the safety rope tightly when falling. Therefore, when the worker changes the working position, the worker's body safety belt is always connected to the fall protection device and can move up and down flexibly without frequent switching, ensuring that the protection of the safety belt is not lost, and saving the worker the operation of switching the protection mounting position.

[0017] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.
[0018] In a specific embodiment, a high-altitude work safety belt anti-fall device is provided, including a traction rope 1, a guide wheel 2, a fixing device and a safety rope 3. The guide wheel 2 in this example is a fixed pulley, which is respectively arranged on the top of the construction surface a1 of the building a and on the opposite side thereof, so that the traction rope 1 can be slid and guided on both sides of the building a.
[0019] The fixing device in this example includes a first fixing device 4 and a second fixing device 5. In this example, the first fixing device 4 is arranged at the bottom of the construction surface of the building a, and the second fixing device 5 is arranged on the opposite side of the bottom of the construction surface a1 of the building a, so that one end of the traction rope 1 can be installed on the first fixing device 4, and the other end can be connected to the second fixing device 5 after passing through the guide wheel 2;
[0020] During installation, the end of the traction rope 1 after being released from the fixing device is connected to the front end of the safety rope 3, and the safety rope 3 can be wound around the guide wheel 2 by pulling the traction rope 1, and the front end of the safety rope 3 can be connected to the second fixing device 5 after the connection end of the traction rope 1 is disassembled, and the rear end of the safety rope 3 is pulled to put the entire safety rope 3 in a taut state. Therefore, by pulling the traction rope 1, the position of the safety rope 3 replaces the installation position of the traction rope 1, thereby realizing the installation of the safety rope 3.
[0021] On this basis, it also includes a safety rope 8 and a fall arrester 6 connected thereto. In this example, the fall arrester 6 is a differential fall arrester. The fall arrester 6 is installed on the safety rope 3, and the safety rope 8 is connected to the operator's body safety belt. When the operator is working, the main rope 7 is used for lifting or protection. However, when the operator moves up and down, the fall arrester 6 will slide along the safety rope 3. If the operator falls, the differential fall arrester will hold the safety rope 3 tightly, thereby being able to pull the operator and prevent an accident. Therefore, when the operator changes the working position, the operator's body safety belt is always connected to the fall arrester and can move up and down flexibly, without the need for frequent switching, ensuring that the safety belt protection is not lost, and saving the operator the operation of switching the protective installation position.
[0022] In addition, since the present application adopts a safety rope 3, the safety rope 3 can be easily laid out through the traction rope 1 and the guide wheel 2. Similarly, when the safety rope 3 is disassembled, the traction rope 1 is connected to the front end of the safety rope 3, and then the safety rope 3 is pulled in the reverse direction so that the traction rope 1 is wrapped around the guide wheel 2 and replaces the position of the safety rope 3. At this time, the safety rope is disassembled, so the safety rope 3 can be inspected and replaced, which is convenient for operation and conducive to the maintenance of the safety rope.
[0023] In light of the above, there are two ways to tighten the safety rope 3 to ensure smooth sliding of the fall arrester 6 and the safety rope 3: First, the rear end of the safety rope 3 is connected to the first fixing device 4. Second, a counterweight is mounted on the rear end of the safety rope 3. The counterweight is heavy enough to cause only slight displacement of the safety rope in the event of a fall.
[0024] In addition, the fixing device in the present application adopts a hook and ring connection structure, which ensures a reliable connection while facilitating connection and disassembly.
[0025] Based on the above-described preferred embodiments of the present invention, and in accordance with the above description, relevant personnel are fully capable of making various changes and modifications without departing from the scope of the technical concept of this invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
