Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude work safety belts, in particular to a high-efficiency fall-prevention five-point safety belt that can be remotely unlocked. Background Art

[0002] The five-point safety belt is currently an essential safety protection equipment for working at heights. The overall composition of the five-point safety belt generally includes a full-body restraint belt consisting of a shoulder strap, a waist belt, a chest strap, and a hip strap, as well as a buffer tether and a hook. The buffer tether is generally composed of two braided ropes of fixed length (usually 2m). One end of the braided rope is connected to the full-body restraint belt, and the other end is hung and fixed on a reliable hanging point through a connecting hook. When the hanging point needs to be moved, one of the hooks needs to be kept stationary, one of the hanging points needs to be untied to the target position, and then the other hook is untied and moved to the target position.

[0003] In actual construction, on the one hand, the fixed-length buffer tether (2m) is relatively long, which may increase the risk of collision during the falling process. On the other hand, the untied buffer tether of the five-point safety belt poses the risk of tripping and mishanging. Furthermore, when the target hanging point is far away from the original hanging point, it is inconvenient to move the hook and ensure its safety. Utility Model Content

DETAILED DESCRIPTION

[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1~2As shown, the embodiment of the utility model proposes an efficient anti-fall five-point safety belt that can be remotely unlocked, including a full-body restraint belt 1 composed of a shoulder strap, a waist belt, a chest belt, and a crotch belt, a differential anti-fall device 2, and a hook device, the differential anti-fall device 2 is fixedly installed on the full-body restraint belt 1, the hook device includes an existing safety hook, the safety hook includes a hook body 4 fixedly connected to the full-body restraint belt 1 through a safety rope 3, an anti-unhooking device 5 hinged on the hook body 4 to achieve locking and unhooking, and a buckle 6 for locking the anti-unhooking device 5, the hook device also includes a first, a second, and a third pulley block 9 and a first and a second two-strand traction rope fixed on the full-body restraint belt 1, the first pulley block 7 is fixed The first traction rope 10 is fixedly installed in the middle part of the hook body 4, the second pulley block 8 is fixedly installed at the position of the hook body 4 corresponding to the anti-unhooking device 5, the third pulley block 9 is fixedly installed at the end of the hook body 4 at the position corresponding to the buckle 6, the first traction rope 10 passes through the first pulley block 7 and is fixedly connected with the top of the hook body 4 and the anti-unhooking device 5, so that the first traction rope 10 is away from the depression of the hook body 4 when it is straightened, and the end of the second traction rope 11 is forked into two long and short sections, the long section of the second traction rope 11 passes through the second pulley block 8 and is fixedly connected with the top of the anti-unhooking device 5 and the hook body 4, and the short section of the second traction rope 11 passes through the third pulley block 9 and is fixedly connected with the buckle 6.

[0017] The working principle is: when moving for high-altitude operations, it is necessary to alternately unlock the safety belt hanging points to move. When the safety hook is hung on the hanging point, the hanging point is located between the first traction rope 10 and the second traction rope 11, which is consistent with the existing safety hook hanging point operation. When unlocking is required, first pull the second traction rope 11 to make the short section of the second traction rope 11 open the buckle 6, and continue to apply force to make the long section of the second traction rope 11 pull open the anti-unhooking device 5, and then pull the first traction rope 10 to make the straightened second traction rope 11 push the hanging point at the recessed part of the hook body 4 out of the hook body 4, thereby realizing the separation of the safety hook from the hanging point, so as to remotely unlock the hook, expand the moving range, and make the weighted safety rope 3 in a tensioned state through the fall arrester. When unlocking another hook, the remote unlocking method avoids the risk of falling and reduces the risk of collision.

[0018] In this embodiment, if Figure 2 As shown, the pulley block is a double pulley structure, and the double pulleys are arranged in parallel so that there is a cavity between the double pulleys for the first traction rope 10 and the second traction rope 11 to pass through. The double pulley structure is used to limit the first traction rope 10 and the second traction rope 11 to prevent the first traction rope 10 and the second traction rope 11 from being separated from the hook body 4 and entangled.

[0019] In this embodiment, the first traction rope 10, the second traction rope 11 and the safety rope 3 are braided ropes of different colors. The safety rope 3 can be blue, the second traction rope 11 can be green, and the first traction rope 10 can be red. When unlocking, pull the green rope first and then the red rope, which is easy to remember and not easy to make mistakes.

[0020] In this embodiment, if Figure 1 , Figure 2 As shown, a plurality of coils 12 are sleeved on the first traction rope 10, the second traction rope 11 and the safety rope 3. The first traction rope 10, the second traction rope 11 and the safety rope 3 are used to be gathered for convenient use.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
