Description

Technical Field

[0001] The utility model belongs to the technical field of construction safety ropes, and in particular relates to a safety rope fixing structure for building construction. Background Art

[0002] Safety ropes are commonly used safety equipment in construction operations. During construction operations, the safety ropes can be connected to set positions and connected to workers or construction machinery to protect them.

[0003] Most of the safety rope fall prevention methods currently used are to fix the ends of the safety rope to indoor load-bearing structures. Since personnel need to move continuously during the operation, a longer safety rope is reserved at the personnel fixed end and the indoor fixed end for movement. If a person falls, due to the long length of the reserved section of the safety rope, the safety rope can only be tightened after the person falls a certain distance. During this process, the kinetic energy generated by the continuously accelerating falling speed and the person's own weight will exert a huge pulling force on the safety rope, so there is a safety hazard of the safety rope being torn apart at the fixed position or the rope breaking. Summary of the Invention

The utility model provides a safety rope fixing structure for construction, which is provided with a locking structure of the safety rope; when the safety rope extends out of one end of the anti-fall fixing box, it is tightened instantly, and the locking structure is driven by the tension of the safety rope to move downward along the limit guide rod, and the contact travel limit switch is used to activate the electric telescopic rod to drive the movable locking platform to cooperate with the fixed locking platform to bite the safety rope through the locking block to prevent it from slipping off, thereby playing a locking and protective role for the safety rope; at the same time, the clamping protrusion and the clamping concave block are used to slide downward along the inclined guide slide and squeeze each other to get closer. Through the clamping convex strip, the safety rope can be firmly locked at the moment of falling, thereby improving the safety protection capability of high-altitude construction workers.

The right side wall of the locking structure 2 and the contact travel limit switch 26 on the inner side surface of the right end of the anti-fall fixing box 1 contact each other, open and start the electric telescopic rod 24, and the electric telescopic rod 24 drives the movable locking platform 22 to move along the slide rail 25 toward the fixed locking platform 21 until it approaches the fixed locking platform 21 and bites the safety rope 10 through the locking block 23 to prevent it from slipping, thereby playing a locking and protection role for the safety rope.

[0029] In this embodiment, a clamping rib 5 for clamping the safety rope is provided on the inner semicircular convex surface of the clamping protrusion 3 and the inner semicircular concave surface of the clamping recess 4, and the outer side surfaces of the clamping protrusion 3 and the clamping recess 4 are set as inclined panels that slide with the inclined guide slide 15; the locking structure 2 moves downward to drive the clamping protrusion 3 and the clamping recess 4 below it to move downward, and the inclined panels on the outer side surfaces of the clamping protrusion 3 and the clamping recess 4 slide downward along the inclined guide slide 15, thereby realizing that the clamping protrusion 3 and the clamping recess 4 are squeezed together and the safety rope 10 is firmly clamped by the clamping rib 5, which well realizes double clamping of the safety rope and prevents the safety rope from slipping.
