Description

Technical Field

[0001] The invention relates to the technical field of iron tower climbing, in particular to a force-bearing locking device. Background Art

[0002] Large electric poles and towers, whether used for power lines or communication lines, have climbing spikes for climbing, but due to the lack of special tools, construction workers or maintenance personnel climb up and down the towers barehanded, without safety belt protection, which is very dangerous. At present, construction workers only wear safety belts, but the current safety belts are inconvenient to climb, and the locks are not convenient to use. For example, the Chinese patent "Construction Safety Belt" with announcement number CN205948215U and announcement date 2017.02.15, the safety belt is hung on the climbing spikes through a locking hook. When climbing, it needs to be repeatedly opened and buckled, which is cumbersome to operate and inconvenient to climb. Summary of the invention

[0003] The present invention provides a force-bearing locking device, which is applied to a safety belt so that a climber can conveniently lock the locking device on a climbing spike when climbing an iron tower or an electric pole. The operation is simple and convenient, and the climbing efficiency can be effectively improved while improving safety.

[0004] The technical solution of the present invention is:

[0005] A force-bearing locking device comprises a grip, a bent hook member is fixedly provided on the top of the grip, an elastic clip is also provided on the grip, the elastic clip comprises an upper clip and a lower clip, the upper clip is provided with a through hole, the lower clip is provided with an insertion hole, the elastic clip is sleeved on the grip through a torsion spring, and the bent hook member is placed in the through hole of the upper clip, the upper clip and the lower clip form an opening shape, and the hook end of the bent member is placed in the opening structure.

[0006] When in use, the force-locking device is connected to the safety belt's protective rope and the backup safety rope respectively. When climbing the iron tower, the construction worker holds the grip and then aligns the opening between the upper clip and the lower clip with the climbing nail, so that the climbing nail contacts the upper clip. The grip is used to apply force downward. At this time, due to the obstruction of the climbing nail, the upper clip is flipped upward, and the lower clip is flipped upward to insert the hook of the hook into the insertion hole of the lower clip, so that the climbing nail can be automatically locked in the hook of the hook. When removing, the grip is used to apply force upward to make the climbing nail contact with the lower clip. At this time, due to the obstruction of the climbing nail, the lower clip is flipped downward, and the hook of the hook is separated from the insertion hole. At the same time, the upper clip is flipped downward to release the lock, so that the force-locking device is separated from the climbing nail. The force-locking device is then used to repeat the above process for the next climbing nail to force lock, so that climbing can be achieved quickly.

[0007] Furthermore, one end of the upper clamp and the lower clamp forms a circular sleeve and is sleeved on the grip through a torsion spring, and the other end is in an eight-shaped opening, which is convenient for guiding the climbing nail to align with the upper clamp for force locking.

[0008] Furthermore, the grip is a square grip ring, which is convenient for construction workers to grip tightly.

[0009] Furthermore, the root of the hook piece is welded to the top of the grip, and the hook piece is a U-shaped hook.

[0010] Furthermore, the grip is integrally formed of galvanized iron material.

[0011] Furthermore, the hook piece is made of galvanized iron.

[0012] Furthermore, the hook piece is integrally formed.

[0013] Furthermore, the gripping portion of the grip is provided with anti-slip grooves to enhance the gripping force.

[0014] Furthermore, the elastic clip is integrally formed.

[0015] Furthermore, the grip is sleeved with an insulating sleeve to improve safety.

[0016] The beneficial effects of the present invention are:

[0017] The force-bearing locking device of the present invention is respectively connected to the protective rope and the backup protective rope of the safety belt. When climbing an iron tower, two force-bearing locking devices are used to lock the climbing nails, which can minimize the safety hazards of going up and down the iron tower. In addition, the force-bearing locking device of the present invention is directly automatically locked by force. It can be locked by buckling the climbing nail with downward force, and can be released from the climbing nail with upward force. It is convenient and quick, and can effectively improve the climbing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
