Description
Technical field
A kind of telescopic oil pipe is the utility model is related to, belongs to hydraulic system technical field.
Background technology
Telescopic working arm is widely used in production in recent years, especially in bargh, telescopic work
Arm loads this field of operation in material and played an important role, and at present, the hydraulic pressure conveying oil pipe of telescopic working arm is all laying
In the outside of working arm, one end connection hydraulic power unit, one end is connected on extensible canopy, then is connected to by flexible pipe inside extensible canopy
On oil cylinder.
The shortcomings that this oil pipe connected mode is：
When the 1st, laying oil pipe, the length of oil pipe will calculate according to distance during telescopic arm range, therefore when flexible
When formula working arm acts, because flexure suspensions phenomenon occurs in long oil pipe.
2nd, oil pipe so can not only drop as the expanding-contracting action of telescopic working arm can make bending repeatedly, stretch action
The resistance to pressure of low oil pipe, and can also reduce oil pipe inevitably with being in contact and rubbing on the outside of working arm due to rocking
Service life.
3rd, oil pipe is laid in outside working arm, the easy weathering under sunlight for a long time.When telescopic working arm exists
When being worked in the complex environments such as underworkings, exposed oil pipe is easily damaged, for example, splashed during explosion rubble,
Sharp stone that ground and metope protrude during work etc..
The content of the invention
For the deficiencies in the prior art, the technical problems to be solved in the utility model is：Provide a installation
Inside telescopic working arm and can and the telescopic oil pipe that act together of oil cylinder.
To achieve the above object, the technical solution adopted in the present invention is：Telescopic oil pipe, including：Oil cylinder（1）With it is flexible
Oil pipe（2）, it is characterised in that telescopic oil tube（2）Positioned at oil cylinder（1）Lower section, be placed in oil cylinder（1）Both sides；Telescopic oil tube（2）
Tight block（11）And oil cylinder（1）Fixed seat（7）It is combined together in a manner of conjunction.
Described oil cylinder（1）Including：Piston rod（3）, cylinder body（4）, connecting plate（5）, straight coupling（6）, fixed seat（7）；
Connecting plate（5）Installed in piston rod（3）Downside front end, straight coupling（6）Installed in connecting plate（5）Lower section, one end connection stretches
Contracting oil pipe（2）Straight joint（8）, the other end one section of hydraulic hose of connection, fixed seat（7）The lower section on rear side of cylinder body, with welding
Mode is connected with cylinder body.
Described telescopic oil tube（2）Including：Straight joint（8）, piston tube（9）, telescopic tube（10）, tight block（11）；Directly
Joint（8）One end and oil cylinder（1）Straight coupling（6）It is connected, one end and piston tube（9）It is connected, piston tube（9）It is embedded in
Telescopic tube（10）In, tight block（11）Positioned at telescopic tube（10）Rear end, with fixed seat（7）It is connected, by telescopic oil cylinder
It is fixed on oil cylinder.
The beneficial effects of the utility model：The utility model uses said structure, and oil pipe is arranged on telescopic working arm
Inside, working arm play a protective role to oil pipe, avoid damage of the extraneous factor to oil pipe, and improve oil pipe uses the longevity
Life.Flexible technology with alloing oil pipe to be acted together with telescopic oil cylinder, solve due to working arm it is flexible caused by oil
Pipe bends the problem that fractures.

Embodiment
As shown in figure 1, telescopic oil pipe includes：Oil cylinder 1, telescopic oil tube 2.Telescopic oil tube 2 is located at the lower section of oil cylinder 1, splits
Both sides.Telescopic oil tube 2 is combined together the fixed seat 7 of tight block 11 and oil cylinder in a manner of conjunction, plays fixed telescopic oil
The effect of pipe.
As Figure 2-3, oil cylinder 1 includes：Piston rod 3, cylinder body 4, connecting plate 5, straight coupling 6, fixed seat 7.Connecting plate 5
The downside front end of piston rod 3 is arranged in a manner of conjunction, for fixing straight coupling 6, two pieces of straight couplings 6 are distinguished in a manner of conjunction
The lower section both sides of connecting plate 5, the straight joint 8 of one end connection telescopic oil tube 2 of straight coupling are fixed on, the other end connects one section of liquid
Flexible pipe is pressed, the hydraulic oil in telescopic oil tube 2 is transported in next oil cylinder by the hydraulic hose of this section.Fixed seat 7 is located at
