Description
Technical field
The present invention relates to a kind of hydraulic support, and in particular to one kind can lateral deviation hydraulic support.
Background technology
Hydraulic support is widely used in colliery pit mining field, the top plate being mainly used to above supported face, prevents from adopting
For coal machine during coal mining, roof caving causes injury to personnel or device damage.In the hydraulic support course of work, the effect of its back timber
In top plate, base acts on bottom plate, and middle hydraulic prop plays a supportive role；If the angle for running into working face is larger, or coal
Layer top plate and bottom slab stress are uneven, will result in top plate and bottom plate produces the phenomenon of sliding, be i.e. top plate and bottom plate produces relative position
The phenomenon of shifting.
Because the hydraulic prop of Normal hydraulic support is rigidly connected with back timber and base, and in the hydraulic support course of work by
To the vertical force for coming from top rock stratum it is larger, cause the frictional force of back timber and top plate larger, when top plate and bottom plate are relatively sliding
During shifting, hydraulic prop and back timber and the continuous damage of base are may result in, or even causes hydraulic support to fail, is mining production band
Carry out huge potential safety hazard.
The content of the invention
The present invention provide one kind can lateral deviation hydraulic support, the back timber and base of the hydraulic support can be respectively with top plate and bottoms
Plate is relatively moved and moved, securely and reliably.
To achieve the above object, the technical solution adopted by the present invention is：One kind can lateral deviation hydraulic support, including hydraulic pressure branch
Post, base, back timber, the hydraulic prop includes lateral deviation pillar and support pillar, the lateral deviation lower rod end lead to the base
Cross be hinged and connected, upper end is hinged and connected with the back timber, it is described support pillar upper end is connected with the back timber, lower end is supported on institute
State on base.
Because the upper and lower side of lateral deviation pillar is hinged with back timber and base, therefore back timber and base relative can produce displacement,
When top plate and bottom plate Relative sliding, back timber can move with top plate, and base moves with bottom plate, hydraulic support is produced side
Partially, destroyed this avoid hydraulic support due to back timber and base Relative sliding；There is provided support pillar, support branch again simultaneously
Post can move left and right, ensure that can lateral deviation hydraulic support have enough support forces.
Further, the back timber both sides are respectively connected with backplate, and the backplate connects perpendicular to back timber, upper end and back timber.
Further, there is slideway the lower end that the support pillar is corresponded on the base, the slideway and the support pillar
Lower end coordinates, and support lower rod end is moved on slideway.
Preferably, the support lower rod end is provided with locking structure.
Preferably, the back timber front end is extended with preceding caving shield, rear end is extended with back screen beam, the preceding caving shield and top
Beam is articulated and connected, its lower end has hydraulic cylinder to be connected with back timber bottom.
One kind provided by the invention can lateral deviation hydraulic support, can with top plate and bottom plate relative movement lateral deviation, not rapid wear
It is bad, while have enough support forces again；In the course of the work, securely and reliably.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, one kind can lateral deviation hydraulic support, including hydraulic prop, base 4, back timber 1, hydraulic prop bag
Include lateral deviation pillar 2 and support pillar 3, the lower end of lateral deviation pillar 2 with base 4 by being hinged and connected, upper end and back timber 1 be hinged and connected,
The upper end of pillar 3 is connected with back timber 1, lower end is supported on base 4 for support.
Because the upper and lower side of lateral deviation pillar 2 is be hinged with back timber 1 and base 4, therefore back timber 1 and base 4 relative can produce
Displacement, as shown in figure 3, when top plate and bottom plate Relative sliding, back timber 1 can move with top plate, and base 4 moves with bottom plate,
Hydraulic support is produced lateral deviation, destroyed this avoid hydraulic support due to back timber 1 and the Relative sliding of base 4；Set again simultaneously
Put support pillar 3, support pillar 3 can move left and right, ensure that can lateral deviation hydraulic support have enough support forces.
During in order to prevent that support from offseting, the back timber 1 of adjacent two hydraulic supports overlaps, and causes hydraulic support phase
Mutually interference, the both sides of back timber 1 are respectively connected with backplate 7, and backplate 7 connects perpendicular to back timber 1, upper end and back timber 1.
In order that support pillar 3 that can be in lateral deviation hydraulic support moves left and right more smooth, corresponding support pillar on base 4
There is slideway 53 lower end, and the slideway 5 coordinates with support pillar 3 lower end, the lower end of support pillar 3 is moved on slideway 5.
In order to prevent can lateral deviation hydraulic support at work, support the lower slide of pillar 3 it is excessively flexible, cause support not
Surely, support pillar 3 lower end is provided with locking structure.
In order that production is safer, prevent the top plate spoil that leaks down from causing danger to lower work personnel, so before back timber
Caving shield 6, rear end are extended with back screen beam 8 before end is extended with, preceding caving shield 6 with back timber 1 is articulated and connected, there is hydraulic cylinder its lower end
It is connected with back timber bottom.
One kind provided by the invention can lateral deviation hydraulic support, can with top plate and bottom plate relative movement lateral deviation, not rapid wear
It is bad, while have enough support forces again；In the course of the work, securely and reliably.
