An electric three-way synchronous take-up and release device

Abstract

The invention discloses an electric three-way synchronous take-up and pay-off device. The device comprises a base, a supporting frame, a driving unit, a transmission unit, a wire coil set and a traction unit. The supporting frame and the driving unit are fixedly mounted on the base. The wire coil set mounted on the supporting frame comprises a front wire coil, a rear wire coil and a top wire coil which are of the same structure. The wire coil set is connected with the transmission unit through the driving unit. The traction unit is used for providing guiding and traction driving force for wires. The driving unit comprises a main body, a reducer and an electromagnetic clutch. When the wires are taken up, the driving unit provides power for rotation of the wire coil set, and the traction unit just achieves the guiding function; and when the wires are paid off, the transmission unit and the main motor are separated through the electromagnetic clutch, and the traction unit provides the traction power. The three ways of wires can be simultaneously and synchronously taken up or paid off, the working efficiency is high, wire tightening or twining can be avoided, the labor intensity is low, the device has the advantages of being compact in structure, easy and convenient to operate and maintain and the like, and the construction cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of electric power construction equipment, in particular to an electric three-way synchronous take-up and release device. Background technique [0002] Wires, cables, and optical cables are the main carriers for power transmission or signal transmission. Whether it is for military or civilian use, there will be situations where cables and optical cables need to be quickly retracted and released indoors and outdoors, especially in various engineering constructions. The usage and laying work are huge. At present, when laying cables in engineering construction, there are mainly two methods, one is to rely on manpower to remove the cables from the cable reel and then lay them; The cable reel is placed on the rotatable take-up and pay-off frame to manually pull the cable or rotate the cable reel to realize the take-up and pay-off. When the diameter of the cable is thick, it is difficult to grasp with the hand, a...

Problems solved by technology

Chinese utility model patent "combined pay-off device" (application number: 201620425406.9) places three rotating pay-off racks on the frame. This device can store and release three bundles of coils at the same time, which solves the problem of the number of coils used by the pay-off device. However, the transmission part of the device is relatively simple and cannot control the speed of wire recovery

In the design of the Chinese practical patent "a wire pay-off" (application number: 201520948397.7), the length adjustment rod is used to adjust the height of the winding cable, and the wire is exported through the wire wheel. The situation where the cable rubs against the corner and the outer skin is damaged, but it is only suitable for the use of a single coil, and it does not have the function of cable recovery

Chinese utility model patent "Multi-channel pay-off device" (application number: 201520801000.1) design includes a folding base, a rotating shaft, a pay-off reel, and an adjustment slot. The wire device can realize the placement of various coils, which improves the work efficiency. The adjustment slot can adjust the clamping of the pay-off reel, which is suitable for pay-off reels of different diameters. This patent solves the problem of using multiple sets of coils at the same time, and Solved the problem of using different types of coils, but does not have the cable recycling function

The Chinese invention patent "Frequency Conversion Electric Cable Rewinding Device" (Application No.: 200910215423.4) puts a motor equipped with a frequency converter on the frame and adjusts the height of the frame through a hydraulic cylinder. This device abandons the manual replacement of traditional cable reels It is the same as the replacement method of manual cooperation with the crane, but this device is only suitable for the use of a single coil, and the work efficiency is low

The Chinese invention patent "weather-resistant wire take-up and pay-off device" (application number: 201510465556.2) adopts the structure of the chassis, winding vertical shaft, motor and two winding stoppers to realize the take-up and pay-off of the device, which saves manpower, but the device There is no clear control on the speed of wire recovery, and the device is only suitable for a single type of coil, which is not universal

Chinese invention patent "a multifunctional cable retracting and unwinding device" (application number: 201610576453.8) uses the control system to control the motor to retract and unwind the wires, and at the same time, an encoder is installed on each driving wheel, which can control the retraction and unwinding in real time Although the speed and length of the wire can be accurately controlled, each driving wheel on the device is driven by a separate motor, which is inconvenient to control and high in cost

The Chinese invention patent "Anti-break take-up and pay-off device" (application number: 201410161126.7) installs a friction disc on the roller shaft of the roller base. The roller shaft is equipped with a compression spring and a compression adjustment handwheel. The take-up handle blocking block that blocks the take-up handle during the line is suitable for winding rollers of different specifications, which can ensure the tension during take-up and take-off, and will not break the wire, but this device is only suitable for single-reel cables manual retraction

Chinese utility model patent "portable grounding resistance test take-up and take-off device" (application number: 201320268828.6) design includes a winding shaft, a winding shaft seat and three winding reels, and the wires are collected on the winding reels by hand, but The device adopts manual way to retract and discharge wires, without self-locking function
