Description

Anti-jamming power optical cable pay-off trolley

technical field

The utility model relates to a power cable pay-off construction tool, in particular to a power optical cable pay-off pulley with the function of preventing the optical cable or traction rope from jamming.

Background technique

Over the years, in the process of laying out the power optical cable, it often happens that the laying cannot be carried out normally due to the jamming of the traction rope and the optical cable in the pay-off block, resulting in rework, idle work and construction quality problems. Therefore, there is an urgent need to find an effective method to fundamentally solve the problem of the jamming of the pay-off trolley during the laying of the power optical cable.

Utility model content

The purpose of this utility model is to provide an anti-jamming power optical cable pay-off tackle, to form a blockage for the optical cable or traction rope at the gap between the left and right outer upper parts of the runner and the left and right splints, so as to avoid Jammed wheel.

The purpose of this new model is achieved in this way: an anti-jamming power optical cable pay-off tackle, the shaft is fixed on the left and right splints, the runner is rotatably mounted on the shaft, and the hook is installed on the top of the left and right splints. An anti-jamming protective strip is respectively welded on the inner side of the left and right splints at the upper position of the running wheel.

The above-mentioned anti-jamming protection bar is made of round steel with a length of 10 cm and a diameter of 8 mm. the

During the construction process of the electric optical cable, first hang the pay-off block on the power line that has been powered off, and synchronously pass the traction rope through the block, and then drag the electric optical cable to a fixed position by the traction rope through the ground traction machine, and take it out after the optical cable is fixed. The wire pulley is lowered, separated from the power line, and the power line is restored to power supply.

The beneficial effect of the new model is: it meets the standard operation requirements of electric optical cable construction, effectively solves the jamming problem of the traction rope and optical cable in the pay-off block during construction, improves the construction efficiency, and prevents the power optical cable from being disconnected due to jamming and other problems to ensure the quality of construction. The pay-off block has the characteristics of convenient disassembly, simple operation, flexibility and practicality, and high reliability.

Detailed ways

Figures 1 and 2 show that the anti-jamming electric cable pay-off block, the shaft 4 is fixed on the left and right splints 2 and 3, the runner 1 is rotatably installed on the shaft 4, and the hook 5 is installed on the left and right On the top of the splint, an anti-jamming protective strip 7,6 is respectively welded on the inner side of the left and right splints 2,3 at the position above the runner 1. A horizontal plate is fixed on the top of the left and right splints, and the hook (with a threaded opening at the bottom) is rotatably installed on the horizontal plate through a nut. The diameters of the two anti-jamming protection strips 6, 7 are not less than the distance between the runner and the left and right splints, so as to prevent the cable from entering to form a jam and affecting the setting-out construction.

The utility model is based on the ordinary pay-off tackle, and is manufactured by adding an anti-jamming protection strip on both sides. The anti-jamming protection strip is a circular steel bar with a length of 10cm and a diameter of 8mm, which are respectively welded to the left side of the ordinary pay-off tackle. , The top of the pulley on the inner side of the right splint is formed.
