Multi-directional pay-off block

Abstract

The invention discloses a multi-directional paying-off tackle applicable to the technical field of electric mounting. The tackle comprises a support and a roller disposed on the support through a roller shaft. The support comprises a lower fixing plate, a first side plate and a second side plate, wherein the first side plate and the second side plate are vertically disposed on two sides of the lower fixing plate, the top ends of the first side plate and the second side plate are connected through a crossbeam, the roller shaft vertical to the two side plates are disposed between the middles of the two side plates, two sides, located on the side plates, of the lower fixing plate are symmetrically provided with four iron pins, a nylon turning bar is sleeved on each iron pin, the second side plate includes a support plate fixed on the lower fixing plate and a movable plate capable of being opened and closed, and a locking mechanism for locking the movable plate is disposed on the outer side of the same. The multi-directional paying-off tackle has the advantages that the tackle is capable of smoothly paying-off in corner paying-off paths, procedures such as wire breaking and connecting can be avoided, work load of operators is reduced, wire connecting points are reduced, potential safety hazard is reduced, and safety performance of an electric system is increased.

Description

technical field [0001] The invention relates to a power installation device, in particular to a pay-off tackle. Background technique [0002] The pay-off block is widely used in the power industry for laying pipelines, which can improve work efficiency and reduce pipeline damage. The traditional pay-off block includes rollers, which are set on the bracket through the pin shaft. When in use, the pay-off block is first suspended in the air or placed on the ground, and secondly, the wire is placed on the roller, and then the free end of the wire is pulled and moved toward Apply force in front, so that the pulley rotates to achieve the purpose of releasing the line. However, in the construction process, due to the complex terrain, there are often many corners in the pay-off path. When using the traditional pay-off block, the line jam problem often occurs, that is, the wire is stuck in the gap between the edge of the roller and the bracket, especially at the corner. Especially ...

Problems solved by technology

This way of laying out wires not only increases the workload of the construction personnel, but also the contacts at the corners are exposed to the outside for a long time, and the contacts will heat up, which seriously affects the safe and stable operation of the power system.
