A cable protection device

Abstract

The invention discloses an inhaul cable protection device comprising an anchoring body, a limiting body, clamping pieces and pushing jack counter-force seat. Inhaul cables are sleeved with the anchoring body, the limiting body and the clamping pieces and penetrate through the front face of the pushing jack counter-force seat. The limiting body is mounted on the front face of the pushing jack counter-force seat, and a limiting body connecting ring is arranged on the side, far from the pushing jack counter-force seat, of the limiting body. Inserting holes are formed in the anchoring body, and the clamping pieces are inserted into the inserting holes. The anchoring body is fixed in the limiting body connecting ring. Any additional parts are not needed, the reliability of the device is improved greatly, and the service life of the device is prolonged greatly; working clamping pieces and an anchoring tool in prestressed concrete can be used as the clamping pieces and the anchoring body, so that the cost is low, and universality is high; the device is low in cost, does not need specially-assigned person for guarding, has self-locking active protection and is high in using safety, low in loss rate and capable of being reused; and the device can be mounted on other parts, construction casualty accidents and the caused economic loss are controlled, and the device is suitable for requirements of different situations.

Description

technical field [0001] The invention relates to a protection device, in particular to a cable protection device. Background technique [0002] The stay cable is the main force-bearing part of the bridge push (drag method) construction, usually composed of several steel strands. During the construction process, a steel strand is often broken due to various reasons, resulting in safety accidents. The cable protection device is mainly used to limit the movement of the steel strand when it is suddenly broken, so as to prevent the operator from being injured. At present, passive protection is commonly used for cable protection in jacking construction, that is, by wearing plastic pipes, winding iron wires, etc., using plastic pipes or iron wires to constrain the range of movement of steel strands when they are broken. This passive protection device is also Can play a certain protective role. [0003] However, there are many problems and disadvantages in this type of protective ...

AI Technical Summary

Problems solved by technology

[0003] However, there are many problems and disadvantages in this type of protective device. Since a single steel strand breaks with great force, the protective effect of this protective device is often not great. It can only reduce the injuries of surrounding operators, and cannot strictly It plays a protective role; secondly, this type of protective device is troublesome to install, and in the process of moving the cable forward, a special person needs to cut the plastic pipe or iron wire continuously, which is cumbersome to operate, affects the speed of the cable, and reduces the efficiency of the push. This has brought inconvenience to people's use
