Container roof operation safety belt restraint device

Abstract

The invention provides a container roof operation safety belt restraint device, which comprises a casing pipe, and two symmetrically arranged L-shaped clamping devices capable of being used independently, wherein each L-shaped clamping device comprises a body, and a connecting arm and a clamping arm which extend inwards from an inner side of the body; a clamping hook groove is formed among the body, the connecting arm and the clamping arm, and hooks a side beam of a container, and the clamping arm is located in a concave wave of the container; or the clamping hook groove hooks corner fittings of the container, and the clamping arm extends into a lock hole from a side surface of the corner fittings; the connecting arm is located on a top face of the container; an end part of the connecting arm is stretched into the casing pipe and is fixedly connected with the casing pipe; a restraint ring for restraining a safety belt is arranged on the casing pipe, or the restraint ring for restraining the safety belt is arranged on each L-shaped clamping device according to the need. The container roof operation safety belt restraint device is arranged on a roof of the container, and the safety belt is restrained on the restraint device, so that when operation workers carry out roof operation, the over-concentrated stress can be effectively avoided, the operation safety of the operation workers can be ensured, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the field of container transportation, in particular to a safety belt fastening device for container top operations. Background technique [0002] A container ship is a transport ship that mainly carries containers, and usually 2-5 layers of containers can be stacked on its deck. Due to the high center of gravity of container ships during cargo transportation, their wind-responsive area is also large, so they will be affected by wind and waves when sailing at sea and shake, which will cause the containers to move with each other. In order to solve the problems referred to above, the common practice is to fix two adjacent containers to each other by the locks on the corners of each box when loading the containers, and then open the locks when the containers are unloaded. When the operator is working on the top of the container above 2 meters, it is a climbing operation. According to regulations, safety belts must be used for cl...

AI Technical Summary

Problems solved by technology

[0004] 1. Before installing the tie bars, the operator stands on the edge of the container. At this time, the safety belt has not been fastened, and there are great dangers and potential safety hazards;

[0005] 2. When the wear gap of the keyhole on the corner fitting is too large, the tie rod will not be clamped firmly, which will bring danger;

[0006] 3. The tie rod is fixed in the top corner piece, resulting in excessive force moment on the root of the tie rod, excessive stress concentrated on the root of the tie rod, and then there is a danger of bending, tearing and breaking at the root of the tie rod, and the safety of the operator cannot be guaranteed to effective protection
