Quickly-constructed protective sleeve for stay wire

Abstract

The invention discloses a quickly-constructed protective sleeve for a stay wire. The quickly-constructed protective sleeve comprises a coarse sleeve for sleeving the stay wire; a gap dividing the sleeve wall of the coarse sleeve into a fixing part and a movable part and extending in the axial direction is formed in the sleeve wall; the upper end of the coarse sleeve is sleeved with a double-sleeve piece; the upper portion of the double-sleeve piece comprises an upper locking piece for sleeving and locking the stay wire; and the lower portion of the double-sleeve piece comprises a lower locking piece which can be inserted into the upper portion of the coarse sleeve, can sleeve the upper portion of the coarse sleeve and can further lock the upper portion of the coarse sleeve. The quickly-constructed protective sleeve has the advantages and effects that the structure is reasonable, assembly is easy, the time and labor are saved, positioning and length-fixed mounting can be achieved according to the actual site position, firmness and reliability are achieved after mounting, the quickly-constructed protective sleeve is not prone to moving when borne by external force, and the damage and disassembly prevention function is achieved.

Description

technical field [0001] The invention relates to a pull wire sheath capable of rapid construction. Background technique [0002] In the erection of power lines, in order to ensure the force balance of the pole, it is necessary to install a stay wire between the pole and the ground. The stay wire is generally a multi-strand steel strand. The uneven force will seriously affect the safety of the entire transmission line. Due to the small surface area of ​​the exposed backguy, it is difficult to attract people's attention visually, which may cause pedestrians or vehicles to collide by mistake, and stubble at the end of the backguy sometimes hurts passing pedestrians. In order to solve the above problems, in actual use, a warning sheath is generally added to the exposed pull wires, so that it can attract people's attention visually, which not only protects the safety of passing pedestrians, but also ensures the safety of the pull wires and power supply lines.

AI Technical Summary

Problems solved by technology

However, the disadvantages of this kind of pull wire sheath are: 1. The pipe body is only set on the stay wire, and a reliable position limit and relative fixation cannot be formed between the pipe body and the stay wire. Therefore, when subjected to wind or other external forces, the sheath will Moving up or down along the pull wire loses its proper warning function; 2. The traditional sheath is a two-body structure, which not only has many connecting parts during installation, but also cumbersome operation, and it is not reliable after installation and has a low service life.
