Description

A kind of scalable hydraulic oil pipe
Technical field
The present invention relates to a kind of hydraulic oil pipe, specifically a kind of scalable hydraulic oil pipe.
Background technology
Low flat bed semi trailer is commonly used to transport heavy-duty car, rail vehicle, mine equipment, forestry machinery, engineering machinery And other heavily loaded cargos, center of gravity is low, stability and safety are good, transports overheight cargo and strong by the ability of crown obstacle, Increasingly it is widely used.Since the size of heavily loaded cargo, the volume that need to transport are different, low flat bed semi trailer is being used When transporting the larger heavily loaded cargo of some volumes, low flat bed semi trailer widen or lengthening is often required to use.Therefore, it uses Telescopic vehicle frame, by movable carriage assembly relative to frame assembly Telescopic movable in the longitudinal direction is fixed, so as to real Now the length of entire vehicle frame adjustably adjusts, and when needing to meet the needs of larger useful load, can extend the length of entire vehicle frame; When conventional in use, then shorten the length of entire vehicle frame, to avoid vehicle it is long and caused by it is various inconvenient for use.At present, It is stretched using hydraulic system driving vehicle frame, the hydraulic oil pipe in hydraulic system is fixed oil pipe, and length cannot be with vehicle frame It stretches and changes, thus the problem of stand stretch can be caused.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of scalable hydraulic oil pipe, stretched with solving vehicle frame, oil The problem of pipe cannot change length and make frame distortion.
To achieve these goals, the present invention uses following technical scheme:
A kind of scalable hydraulic oil pipe, two groups of multistage oil pipes including being responsible for and being connected to the supervisor both ends, often The multistage oil pipe of group includes the multi-stage expansion sleeve being set with successively, between the adjacent extension sleeve and level-one extension sleeve and master It is connected between pipe by being slidably and sealingly connected with mechanism.
It is described be slidably and sealingly connected with mechanism include pressure cap and piston, wherein piston be hollow structure, the adjacent telescopic It is slidably connected between cylinder and between level-one extension sleeve and supervisor by the piston, the end of the supervisor and multi-stage expansion sleeve Portion is connected with pressure cap, and the pressure cap is used for the axial limiting of the opposite lateral expansion sleeve slided.
The pressure cap is ladder shaft-like, and larger diameter end is equipped with internal thread, for the lateral expansion sleeve with opposite slip It is threadedly coupled, smaller diameter end is equipped with pilot hole, and the pilot hole is used to be oriented to the lateral expansion sleeve of opposite slip.
Sealing ring is equipped between the inner wall of the piston and supervisor or multi-stage expansion sleeve.
One end of the extension sleeve is fixedly connected with the piston, and the other end is equipped with outer for what is connect with the pressure cap Screw thread.
The piston is an integral structure with the extension sleeve.
The equal length of the multi-stage expansion sleeve.
Advantages of the present invention and advantageous effect are:The present invention is stretched by vehicle frame and the length for changing oil pipe, flexibility It is stronger, the problem of avoiding frame distortion.The present invention, which stretches or contracts with vehicle frame, forms synchronous close fit, has reached because vehicle frame is stretched Contracting and hydraulic oil pipe also retractable purpose.
Description of the drawings
Fig. 1 is the structure diagram of stretching state of the present invention;
Fig. 2 is the structure diagram of contraction state of the present invention.
In figure:1 is supervisor, and 2 be first stage piston, and 3 be level-one pressure cap, and 4 be level-one extension sleeve, and 5 be second piston, and 6 are Two level pressure cap, 7 be two level extension sleeve, and 8 be three-level piston, and 9 be three-level pressure cap, and 10 be three-level extension sleeve, and 11 is close for level-one Seal, 12 be two and sealing ring, and 13 be three-level sealing ring.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, it is right in the following with reference to the drawings and specific embodiments The present invention is described in detail.
As shown in Figs. 1-2, a kind of scalable hydraulic oil pipe provided by the invention including supervisor 1 and is connected to described Two groups of multistage oil pipes at 1 both ends are responsible for, every group of multistage oil pipe includes the multi-stage expansion sleeve being set with successively, adjacent described flexible It is connected between sleeve and between level-one extension sleeve and supervisor 1 by being slidably and sealingly connected with mechanism.
It is described be slidably and sealingly connected with mechanism include pressure cap and piston, wherein piston be hollow structure, the adjacent telescopic It is slidably connected between cylinder and between level-one extension sleeve and supervisor 1 by the piston, the supervisor 1 and multi-stage expansion sleeve End is connected with pressure cap, and the pressure cap is used for the axial limiting of the opposite lateral expansion sleeve slided.
The pressure cap is ladder shaft-like, and larger diameter end is equipped with internal thread, and smaller diameter end is equipped with pilot hole, and the pressure cap leads to It crosses internal thread to connect with the opposite lateral expansion bush whorl slided, the pilot hole of the pressure cap is used for the inside to opposite slip Extension sleeve is oriented to.
Sealing ring is equipped between the piston and supervisor 1 or the inner wall of multi-stage expansion sleeve.One end of the extension sleeve It is fixedly connected with the piston, the other end is equipped with the external screw thread for being connect with the pressure cap.
One end of the extension sleeve is an integral structure with the piston, the equal length of the multi-stage expansion sleeve.
In one embodiment of the invention, 1 both ends of the supervisor are connected separately with two groups of three-level oil pipes, and every group of three-level oil pipe is equal Including the level-one extension sleeve 4, two level extension sleeve 7 and three-level extension sleeve 10 being set with successively, the level-one extension sleeve 4, One end of two level extension sleeve 7 and three-level extension sleeve 10 is connected with first stage piston 2, second piston 5 and three-level piston 8 in turn, The other end is equipped with external screw thread.The first stage piston 2 and the inner wall of supervisor 1 are slidably connected, and sealed by primary seal circle 11; The both ends of the supervisor 1 are equipped with external screw thread and are threadedly coupled with two level-one pressure caps 3, and the level-one extension sleeve 4 passes through level-one 3 axial limiting of pressure cap.Second piston 5 and the inner wall of level-one extension sleeve 4 are slidably connected, and are sealed by two and sealing ring 12, The other end of level-one extension sleeve 4 is connected with two level pressure cap 6, and two level extension sleeve 7 passes through 6 axial limiting of two level pressure cap.Three-level Piston 8 and the inner wall of two level extension sleeve 7 are slidably connected, and are sealed by three-level sealing ring 13, two level extension sleeve 7 it is another End is connected with three-level pressure cap 9, and three-level extension sleeve 10 passes through 9 axial limiting of three-level pressure cap.
