Abstract
The utility model relates to a high-flow high-pressure double-expansion pipe, which at least comprises a radial oil delivery pipe, a through body and an axial oil delivery pipe. The double-expansion pipe is characterized in that a cylinder body of an expansion oil pipe is arranged on a fixed beam; the axial oil delivery pipe penetrates through the cylinder body, and is in sliding connection with the cylinder body; the front end of the axial oil delivery pipe is connected with the through body; seals and guide sleeves are arranged at the two ends of the through body; the tail end of the radial oil delivery pipe is sealed, and the radial oil delivery pipe penetrates through the through body, and is in sliding connection with the through body; and the front end of the radial oil delivery pipe is connected with a hydraulic execution mechanism through a through flange. According to the double-expansion pipe, high-flow high-pressure oil can be supplied on a movement part, and the radial displacement of the movement part deviated from a preset movement direction also can be absorbed, so that the problem of oil leakage caused by the eccentricity of the axial oil delivery pipe is solved.
Description
Technical field
The utility model patent is the big-flow high-pressure oil Supply Method of hydraulic actuator on a kind of moving element, especially in non-moving direction two telescopic pipes of big-flow high-pressure on the moving element of larger adjustment requirement is arranged.
Background technique
The high pressure oil supply of hydraulic actuator can realize by flexible pipe usually on the moving element, but also infeasible by the flexible pipe fuel feeding for the hydraulic actuator that high pressure oil flow demand is large, this is because the flexible pipe bore is larger withstand voltage poorer on the one hand, the heavy caliber high pressure flexible pipe is difficult to look for, the heavy caliber high pressure flexible pipe is very thick on the other hand, flexible very poor, the advantage of flexible pipe fuel feeding has also just been lost; If adopt single telescopic oil tube device, only have a straight line (on moving direction) and two degrees of freedom of a rotation, because the requirements such as precision, moving element generally requires to have a certain amount of adjustment in non-moving direction, can cause the other strength of single telescopic oil tube device, cause uneven wear, even cause the conduit cracking.
The model utility content
The purpose of this utility model provides the two telescopic pipes of big-flow high-pressure, has solved the big-flow high-pressure oil supply problem that hydraulic actuator on the moving element of larger adjustment requirement is arranged in non-moving direction.
The technological scheme of model utility is the two telescopic pipes of big-flow high-pressure, at least comprise: radially transport pipe, entire body, axial transport pipe, it is characterized in that: the cylinder body of telescopic oil tube is installed on the fixed beam, axially transport pipe passes in the middle of cylinder body, be slidingly connected with cylinder body, axially the front end of transport pipe links to each other with entire body, sealing and guide pin bushing are equipped with in the entire body two ends, the radially transport pipe of endcapped passes in the middle of entire body, radially be slidingly connected between transport pipe and the entire body, radially the front end of transport pipe links to each other with hydraulic actuator by through flange.
Described axial transport pipe in cylinder body along its axial back and forth movement.
Described radially transport pipe in entire body along its axial back and forth movement.
The beneficial effects of the utility model: the utility model provides big-flow high-pressure oil two telescopic pipe fuel supply methods, the method is when realizing the supply of moving element big-flow high-pressure oil, can also absorb the radial displacement that moving element departs from its pre-motion orientation, avoid the axial transport pipe off-centre of bringing thus and the Leakage that produces.

Embodiment
Embodiment 1
The two telescopic pipes of a kind of big-flow high-pressure, this device comprises at least: radially transport pipe 2, entire body 3, axial transport pipe 5, it is characterized in that: the cylinder body 6 of telescopic oil tube is installed on the fixed beam, axially transport pipe 5 passes in the middle of cylinder body 6, be slidingly connected with cylinder body 6, axially the front end of transport pipe 5 links to each other with entire body 3, sealing and guide pin bushing 10 are equipped with in entire body 3 two ends, the radially transport pipe 2 of endcapped passes in the middle of entire body 3, radially be slidingly connected between transport pipe 2 and the entire body 3, radially the front end of transport pipe 2 links to each other with hydraulic actuator by through flange 1.
Embodiment 2
As depicted in figs. 1 and 2, the two telescopic pipe oil supplying device main parts size of big-flow high-pressure oil comprise through flange 1, radially transport pipe 2, entire body 3, mounting flange 4, axially transport pipe 5, cylinder body 6, locking nut 7 and safety cover 8.This device is installed on the cylinder body 6 of telescopic oil tube on the fixed beam 9 by tightening nut 7, and the axial transport pipe 5 of endcapped passes in the middle of cylinder body 6, and sealing and guide pin bushing 10 are equipped with in cylinder body 6 two ends, and axially transport pipe 5 can be along its axial back and forth movement in cylinder body 6; Axially the front end of transport pipe 5 links to each other with entire body 3 by mounting flange 4, and the radially transport pipe 2 of endcapped passes in the middle of entire body 3, and sealing and guide pin bushing 10 are equipped with in entire body 3 two ends, and radially transport pipe 2 can be along its axial back and forth movement in entire body 3; Radially the front end of transport pipe 2 links to each other with hydraulic actuator by through flange 1.End at this device is equipped with safety cover 8, prevents that axial transport pipe 5 from causing injury to the people when retreating.
During the two telescopic pipe oil supplying device work of big-flow high-pressure oil, high pressure oil enters behind the cylinder body 6 and can enter in the axial transport pipe 5 from the hole on the axial transport pipe 5, then enter radially transport pipe 2 by entire body 3, enter hydraulic actuator by through flange 1 again, satisfy its oil sources demand.
