Abstract
Hydraulic pressure wire grip relates to the overhead transmission line field. Including the hydraulic system of hydraulic motor with the work of control hydraulic motor, hydraulic motor's output connect the retarder, the hydraulic pressure turn -buckle is connected to the output of reduction gear. The utility model discloses a replace manual work by machinery under the particular surroundings, avoided the production safety hidden danger that artifical high altitude construction probably produced. The utility model discloses alleviate intensity of labour, improved work efficiency and economic benefits. Its work efficiency is more than 4 times of artifical hand power wire grip.
Description
Technical field
This utility model relates to field of overhead power transmission lines, is specially a kind of hydraulic line tightening machine.
Background technology
Overhead transmission line is when payingoff construction, owing to being limited by outdoor high altitude conditions, when adjusting power line cable unwrapping wire length, owing to cable is longer, heavier, when constructing the most at the scene, Lever Blocks is generally used to complete the adjustment to cable unwrapping wire length, owing in work high above the ground, Lever Blocks operation not only inconvenient, speed slowly, and has bigger construction safety hidden danger, then, to be how job site problem in the urgent need to address by pull tightener being improved to machinery tightener.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic line tightening machine, replaces manual work, can effectively reduce labor intensity, and improves work efficiency.
The technical scheme realizing above-mentioned purpose is: hydraulic line tightening machine, it is characterised in that: including hydraulic motor and control the hydraulic system of hydraulic motor work, the outfan connection reducer of described hydraulic motor, the outfan of decelerator connects hydraulic wire grip.
Described hydraulic system includes fuel tank, check valve, overflow valve, reversal valve, hydraulic pump and drives the electromotor of hydraulic pump works, the input of described hydraulic pump connects fuel tank, hydraulic pressure delivery side of pump connects check valve and overflow valve respectively, the port of export of described overflow valve connects fuel tank, the port of export of described check valve connects pressure oil port P of reversal valve, the oil return inlet T of reversal valve connects fuel tank, concatenates hydraulic motor between actuator port A, B of reversal valve.
Preferably due to Electric control is easily subject to length of cable constraint, electromotor of the present utility model is gasoline engine, conveniently moving,
Preferably, it is serially connected with filter between input and the fuel tank of described hydraulic pump, it is to avoid oil circuit blocks.
Preferably, it is connected to Pressure gauge by the outfan of described check valve, it is simple to oil circuit monitoring state.
Preferably, described reversal valve passes through Single-chip Controlling.
The beneficial effects of the utility model:
1, this utility model achieves and is replaced manual work by machinery in particular circumstances, it is to avoid artificial work high above the ground issuable production safety hidden danger.
2, this utility model utilizes single-chip microcomputer that the control of reversal valve reaches to control rotating speed and the stroke of reductor, it is achieved the adjustment to unwrapping wire cable length.
3, this utility model alleviates labor intensity, improves work efficiency and economic benefit.Its work efficiency is more than 4 times of artificial hand elastic threads machine.
4, this utility model passes through Single-chip Controlling, can realize the long-range operation that high-altitude unwrapping wire cable length adjusts.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model includes hydraulic motor 1 and controls the hydraulic system 2 of hydraulic motor 1 work, the outfan connection reducer 3 of hydraulic motor 1, the outfan of decelerator 3 connects hydraulic wire grip 4.
Hydraulic system 2 includes fuel tank 5, check valve 6, overflow valve 7, filter 8, reversal valve 9, hydraulic pump 12 and drives the gasoline engine 10 of hydraulic pump 12 work, the input of hydraulic pump 12 connects fuel tank 5 by filter 8, the outfan of hydraulic pump 12 connects check valve 6 and overflow valve 7 respectively, the port of export of overflow valve 7 connects fuel tank 5, the port of export of check valve 6 connects pressure oil port P of reversal valve 9, the oil return inlet T of reversal valve 9 connects fuel tank 5, concatenates hydraulic motor 1 between actuator port A, B of reversal valve 9.
The outfan of check valve 6 is also other is connected to Pressure gauge 11, and reversal valve 9 passes through Single-chip Controlling.
During utility model works, starting gasoline engine 10 and drive hydraulic pump 9 to work, hydraulic oil drives hydraulic motor 1 to rotate through check valve 6, reversal valve 9.
Reversal valve 9 of the present utility model, by Single-chip Controlling, switches the rotation direction of hydraulic motor 1.
