Description
Technical field
The present invention relates to a kind of mining edge floating type hydraulic support.
Background technology
Existing hydraulic support occurs between hydraulic support top board and back when geology hardness is bigger is run into, often
There is larger gap, effective Area of bearing is smaller, the support effect of hydraulic support is substantially reduced and brought greatly to mineral products production
Potential safety hazard.
The content of the invention
For the problem that above-mentioned prior art is present, the present invention provides a kind of mining edge floating type hydraulic support, originally sets
The standby gap made up to gap offer fine sand by hydraulic support itself between hydraulic support and back.
To achieve these goals, the technical solution adopted by the present invention is：A kind of mining edge floating type hydraulic support, bag
Base and support footstock are included, is connected by four hydraulically extensible bars between base and support footstock, described support footstock upper end
The edge in face is uniformly placed with multiple hydraulic rams.
Described support footstock has four walls and bottom, forms the spacious chamber of a pond shape half, and its laid inside has carefully
Sand, described bottom has small opening, and piston cylinder is connected below small opening, and piston cylinder bottom is provided with the piston for sliding up and down, piston
Bottom is connected with piston driving plate, and piston driving plate two ends are separately installed with telescopic hydraulic post, and the other end of telescopic hydraulic post connects
Connect the bottom of support footstock.
The bottom of described support footstock is skewed, height of the small opening horizontal level less than other planes of bottom.
The beneficial effects of the invention are as follows：The edge of support footstock upper surface is uniformly placed with multiple hydraulic rams.Each
Hydraulic ram can as needed adjust height, and the field condition according to mine is adjusted slightly hydraulic ram, is formed different
Bearing height, more preferably, support footstock has four walls and bottom to support effect, forms a pond shape, and described bottom has
Small opening, connects piston cylinder below small opening, piston cylinder bottom is provided with the piston for sliding up and down, and is provided with described piston cylinder thin
Sand, piston base is connected with piston driving plate, and piston driving plate two ends are separately installed with telescopic hydraulic post, telescopic hydraulic post it is another
The bottom of one end connection support footstock, simultaneously non-direct contact between support footstock and back, because support footstock has four
Wall and bottom, form half open cavity of pond shape, and fine sand is equipped with half open cavity so that support footstock and lane
Contacted by fine sand between road top board, due to the changeable attribute of fine sand so that support footstock is big with back contact surface, base
Plinth is firm, and by piston driving plate come the up and down motion with piston, and then the fine sand top inside piston cylinder is got on, energy
The height of fine sand, strengthens the thickness of fine sand to increase compression strength enough in the spacious chamber of adjustment pond shape half.
Brief description of the drawings

Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-3, a kind of mining edge floating type hydraulic support, including base 1 and support footstock 3, base and branch
Connected by four hydraulically extensible bars 2 between support seat, the edge of described support footstock upper surface is uniformly placed with multiple liquid
Coping block 4.Each hydraulic ram can as needed adjust height,
Described support footstock 3 has four walls and bottom, forms the spacious chamber of a pond shape half, and its laid inside has fine sand,
Described bottom has small opening 9, and piston cylinder 5 is connected below small opening, and piston cylinder bottom is provided with the piston 6 for sliding up and down, piston
Bottom is connected with piston driving plate 7, and piston driving plate two ends are separately installed with telescopic hydraulic post 8, the other end of telescopic hydraulic post
The bottom of connection support footstock, is so moved up and down by the telescopic band piston driving plate of telescopic hydraulic post, and then drive is lived
Plug motion is upper and lower.
The bottom of described support footstock is skewed, height of the small opening horizontal level less than other planes of bottom.
The beneficial effects of the invention are as follows：The edge of support footstock upper surface is uniformly placed with multiple hydraulic rams.Each
Hydraulic ram can as needed adjust height, and the field condition according to mine is adjusted slightly hydraulic ram, is formed different
Bearing height, support effect is more preferable,
Support footstock has four walls and bottom, forms a pond shape, and described bottom has small opening, is connected below small opening and lived
Plug tube, piston cylinder bottom is provided with the piston for sliding up and down, and fine sand is provided with described piston cylinder, and piston base is connected with work
Plug driving plate, piston driving plate two ends are separately installed with telescopic hydraulic post, the other end connection support footstock of telescopic hydraulic post
Bottom, simultaneously non-direct contact between support footstock and back, because support footstock has four walls and bottom, forms one
Half open cavity of individual pond shape, fine sand is equipped with half open cavity so that by thin between support footstock and back
Sand contact, due to the changeable attribute of fine sand so that support footstock is big with back contact surface, is built on the rock, and pass through
Piston driving plate carrys out the up and down motion with piston, and then the fine sand top inside piston cylinder is got on, and can adjust pond shape half
The height of fine sand, strengthens the thickness of fine sand to increase compression strength degree in spacious chamber.
