Description

Overhead line device for power equipment construction

Technical Field

The invention relates to the technical field of power construction equipment, in particular to a wire lifting device for power equipment construction.

Background

The overhead line construction is an installation procedure of erecting the overhead line on the assembled tower by using the connecting hardware fitting and the insulator string, and is a finishing stage of the power transmission line construction engineering and a main procedure in the overhead power transmission line construction, and the task of the overhead line construction is to erect the wires and the lightning conductor on the assembled tower according to the designed overhead line stress.

At present, operating personnel often need use the overhead line pulley device when the overhead line is under construction to come the installation of auxiliary and protection cable to erect, however current overhead line pulley device is at in-service use's in-process, because it often can expose in the external world for a long time, thereby easily lead to its own pulley rotary mechanism to take place corrosion, when operating personnel used once more, not only lead to pulley rotary mechanism aggravate wearing and tearing easily, and also can take place the not smooth condition of rotation, the efficiency of cable erection has been influenced, the use of operating personnel has brought inconvenience, simultaneously, the pulley structure that current overhead line pulley device itself was installed is generally fixed, can't adjust the inside interval of pulley, make the inconvenient cable inlet wire auxiliary transport to different sizes of operating personnel, thereby the range of application of device has been reduced, and, current overhead line pulley device is carrying the in-process to the cable, because its pulley structure does not set up corresponding protection structure, thereby easily lead to the cable to appearing wearing and tearing by a wide margin in the in-process of carrying, and then influence the life of cable has been carried out, therefore need to improve it.

For example, patent application number CN202110487154.8, an overhead line construction equipment that power equipment used, including the side bearer, the inside fixed mounting of side bearer has the cotton piece of oil absorption, the side round mouth that is located the cotton piece outside of oil absorption is offered to the inside of side bearer, movable sleeve has cup jointed the dwang between the cotton piece of oil absorption, through setting up movable block, stiff spring, oil storage chamber and piston piece, because the movable block is rotating and be in the piston piece position time, because the elasticity effect of stiff spring will move the piston piece upwards this moment, and because the effect of pressure will make the inside lubricating oil of oil storage chamber spout blowout for the cotton piece of oil absorption can be abundant absorption, so that follow-up lubrication to the surface at dwang both ends, the effectual dwang of having ensured wholly the smoothness when rotating, and reduced wearing and tearing, the operation of giving operating personnel has brought convenience.
