Description
Technical field
The present invention relates to a kind of mine hydraulic brackets.
Background technology
Existing hydraulic support when encounter geology hardness it is larger when, often will appear between hydraulic support top plate and back
There are larger gap, effective bearing area is smaller, and the support effect of hydraulic support is substantially reduced to be brought greatly to mineral products production
Security risk.
Invention content
In view of the above existing problems in the prior art, the present invention provides a kind of mine hydraulic bracket, this equipment passes through hydraulic pressure
Holder itself provides fine sand to gap and makes up the gap between hydraulic support and back.
To achieve the goals above, the technical solution adopted by the present invention is：A kind of mine hydraulic bracket, including pedestal, liquid
Cylinder pressure, hydraulic stem and support footstock, hydraulic cylinder are mounted on the base, and hydraulic stem is mounted on roof supporting.
The support footstock has four walls and bottom, forms half spacious chamber of a pond shape, and laid inside has carefully
Sand, the bottom have leakage hole, are connected to piston cylinder below leakage hole, piston cylinder lower part is equipped with the piston slided up and down, piston
Bottom is connected with piston driving plate, and piston driving plate both ends are separately installed with telescopic hydraulic column, and the other end of telescopic hydraulic column connects
Connect the bottom of support footstock.
Antileaking plate pedestal is installed, Antileaking plate hydraulic cylinder is mounted on Antileaking plate pedestal on the outside of the support footstock surrounding
On, Antileaking plate is hinged with Antileaking plate pedestal, the hydraulic stem connecting anti-leak plate of Antileaking plate hydraulic cylinder, is realized by telescopic hydraulic cylinder anti-
The rotation of bushing
The bottom of the support footstock is to tilt to fill, and leakage hole horizontal position is less than the height of other planes of bottom.
The beneficial effects of the invention are as follows：It supports footstock that there is four walls and bottom, forms a pond shape, the bottom
With leakage hole, piston cylinder is connected to below leakage hole, piston cylinder lower part is equipped with the piston slided up and down, is installed in the piston cylinder
There are fine sand, piston base to be connected with piston driving plate, piston driving plate both ends are separately installed with telescopic hydraulic column, telescopic hydraulic column
Other end connection support footstock bottom, support between footstock and back and non-direct contact, due to support footstock tool
There are four walls and bottom, form half open cavity of a pond shape, fine sand is equipped in half open cavity so that support footstock
It is contacted by fine sand between back, due to the changeable attribute of fine sand so that support footstock and back contact surface
Greatly, it is built on the rock, and by piston driving plate come the up and down motion with piston, and then will be on the fine sand top inside piston cylinder
It goes, the height of fine sand in half spacious chamber of pond shape can be adjusted, enhance the thickness of fine sand to increase compression strength.

Specific implementation mode
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, a kind of mine hydraulic bracket, including pedestal 1, hydraulic cylinder 2, hydraulic stem 3 and support footstock 4, hydraulic pressure
Cylinder is mounted on the base, and hydraulic stem is mounted on roof supporting.
The support footstock 4 has four walls and bottom, forms half spacious chamber of a pond shape, and laid inside has carefully
There is leakage hole 9, leakage hole 9 to be connected to piston cylinder 12 below for sand, the bottom, and 12 lower part of piston cylinder is equipped with the piston slided up and down
13, piston base is connected with piston driving plate, and 11 both ends of piston driving plate are separately installed with telescopic hydraulic column 10, telescopic hydraulic column
The bottom of 10 other end connection support footstock 4.
The bottom of the half spacious chamber of pond shape of the described support footstock is to tilt to fill, leakage hole horizontal position less than bottom other
The height of plane.In this way, when piston 13 is retracted downwards, fine sand also can automatically be retracted along leakage hole.
Antileaking plate pedestal 7 is installed, Antileaking plate hydraulic cylinder 5 is mounted on Antileaking plate pedestal on the outside of the support footstock surrounding
On 7, Antileaking plate 8 is hinged with Antileaking plate pedestal 7,5 hydraulic stem of Antileaking plate hydraulic cylinder, 6 connecting anti-leak plate 8, passes through telescopic hydraulic cylinder reality
The rotation of existing Antileaking plate 8, prevents the leakage of fine sand.
The beneficial effects of the invention are as follows：It supports footstock that there is four walls and bottom, forms a pond shape, the bottom
With leakage hole, piston cylinder is connected to below leakage hole, piston cylinder lower part is equipped with the piston slided up and down, is installed in the piston cylinder
There are fine sand, piston base to be connected with piston driving plate, piston driving plate both ends are separately installed with telescopic hydraulic column, telescopic hydraulic column
Other end connection support footstock bottom, support between footstock and back and non-direct contact, due to support footstock tool
There are four walls and bottom, form half open cavity of a pond shape, fine sand is equipped in half open cavity so that support footstock
It is contacted by fine sand between back, due to the changeable attribute of fine sand so that support footstock and back contact surface
Greatly, it is built on the rock, and by piston driving plate come the up and down motion with piston, and then will be on the fine sand top inside piston cylinder
It goes, the height of fine sand in half spacious chamber of pond shape can be adjusted, enhance the thickness of fine sand to increase compression strength.
