Abstract

The invention discloses a multifunctional stringing auxiliary device for a power distribution line, which comprises a base. The bottom part of the base is provided with a lower locking device in locking match with an electric pole cross arm; a support is fixedly arranged on the base; the support is hinged with a supporting cylinder through a support shaft; a lower positioning device for enabling the supporting cylinder to be positioned and matched is arranged on the support; the upper end of the supporting cylinder is provided with an upper gear rotating close to the outer side surface of a main supporting plate through a rotation connection device; an upper positioning device in clamping and positioning match with teeth of the upper gear is arranged on the supporting cylinder; an upper support is hinged at the upper part of the upper gear; and an upper locking device is arranged between an auxiliary supporting plate and the upper support. The multifunctional stringing auxiliary device for the power distribution line has the advantages that the mounting is convenient; the fixing is reliable; disassembly is simple; the pay-off height can be adjusted freely according to the actual height of an electric pole insulator; the pay-off cable length can be automatically determined; one-time assembly and disassembly are needed for one-time stringing, a wire only needs to be translated after stringing operation, the wire tightness before and after stringing is consistent, the quality is ensured, and the operation can be done by one person.

Description

technical field

[0001] The invention relates to a multifunctional electric power distribution line stringing auxiliary device. Background technique

[0002] The pay-off block is a tool that must be used in the construction of power lines. The main structure is composed of aluminum or nylon pulleys, frame fixing devices, hooks or U-shaped groove stabilizing devices. Using the pulley during the line erection and tensioning process can reduce the wire Excellent frictional resistance, prevent wire strand damage and insulation layer damage, and can increase construction speed and reduce power outage time.

[0003] Now in the construction of 10kV and below power lines, the distance between the U-shaped groove stabilizer and the top of the pulley is about 140mm for the pay-off tackle used, while the height of the P-15 rod insulator is about 240mm, and the height of the P-20 rod insulator is about 140mm. The height of the insulator is about 350mm, the pulley is short, the insulator...

Embodiment Construction

[0029]As shown in the figure, the multi-functional power distribution line stringing auxiliary device includes a base 1, and a lower locking device that is locked and matched with the cross arm 0 of the pole is provided at the bottom of the base. 1. The upper plate 031 extending horizontally at the bottom. The rear end of the upper plate 031 is vertically fixed with a vertical plate 032 extending downward. A screw hole 034 is provided, and the screw hole 034 is screwed with a positioning bolt 036 clamping the horizontal plate 035 of the cross arm 0 in the cavity between the upper plate 031 and the lower plate 032, and the base is fixed with a bracket 2, the bracket A support tube 4 is hinged through the support shaft 3, and the lower section of the support tube is fixed with a lower gear 18 coaxially arranged with the support shaft. There are two main struts 6 and auxiliary struts 7 that extend upwards and are arranged in parallel. A main wheel shaft 8 that is parallel to the ...
