A line take-up and release device for field line erection

Abstract

The present invention provides a retracting and releasing device for field line erection, which includes a mobile base, a retractable support mechanism arranged on the mobile base, a fixing mechanism arranged on the mobile base for fixing, and a The traction mechanism on the mobile base and matched with the retractable support mechanism, the overturning mechanism provided on the bottom surface of the mobile base, and the mobile base used to control the 1. The control mechanism of retractable support mechanism, traction mechanism and overturning mechanism; the invention not only adapts to the needs of erecting lines in different terrains, realizes the ability to cross complex terrains, but also can achieve balance and stability, and can also realize the function of source winding.

Description

technical field [0001] The invention relates to the technical field of power transmission line erection equipment, in particular to a line retracting and releasing device for field line erection. Background technique [0002] For the erection of transmission lines, especially when erecting transmission lines outdoors, due to the complex and changeable outdoor terrain, for transmission lines, it is difficult to place the reel in a suitable position, and it is difficult to prevent balance due to terrain reasons, while the transmission line After the erection is completed, it needs to be tightened to make the wire erection comply with the regulations. The traditional method is to set a winch at the starting end for tension, but this method often causes cable sheath strain, and in order to avoid cable surface strain and cause cable breakage The phenomenon. [0003] The authorized announcement number is CN206922328U, which discloses a cable pay-off device for construction, inclu...

Problems solved by technology

[0002] For the erection of transmission lines, especially when erecting transmission lines outdoors, due to the complex and changeable outdoor terrain, for transmission lines, it is difficult to place the reel in a suitable position, and it is difficult to prevent balance due to terrain reasons, while the transmission line After the erection is completed, it needs to be tightened to make the wire erection comply with the regulations. The traditional method is to set a winch at the starting end for tension, but this method often causes cable sheath strain, and in order to avoid cable surface strain and cause cable breakage The phenomenon

[0003] The authorized announcement number is CN206922328U, which discloses a cable pay-off device for construction, including a vehicle frame, a support rod arranged on the vehicle frame, a wire reel fixing device, a pay-off reel and a wire reel unwinding device; The side is provided with a telescopic wheel frame; the wheel frame is provided with traveling wheels; one end of the support rod is connected to the frame through the drive assembly; the other end of the support rod is provided with a wire reel fixing device; the pay-off reel is set on the wire reel fixing device ;The wire reel fixing device is provided with a wire reel unwinding device, although it can be moved and adjusted, it still cannot solve the problem of wire retraction and inability to adapt to complex terrain

[0004] In the authorized announcement number CN206384662U, a new type of cable retractable turntable is disclosed, which relates to the field of cable production and includes a drive shaft, a base, a cable reel, a drive motor and a rotating chassis. The drive shaft is vertically arranged on the upper part of the base, and the cable The disc is welded on both sides of the drive shaft. The cable disc includes an upper cable disc and a lower cable disc. The drive motor is arranged above the upper cable disc. The rotating chassis is arranged between the lower cable disc and the base. The drive shaft There is a partition plate in the middle, fixed hooks are provided on the upper cable tray and the lower cable tray, the rotating chassis includes a drive shaft connected by a bearing, circular through holes are evenly distributed on the outer side of the rotating chassis, and the circular There are balls in the through holes, and a braking device is provided on one side of the rotating chassis. The braking device includes a pedal and a brake lever welded to each other. However, the terrain problem has not been solved, the source winding has not been solved, and the realization of The phenomenon of ability to cross difficult terrain
