Abstract

A kind of hydraulic prop post footwear, including gripper shoe, form sunk structure, are provided with column casing in the middle part of the upper surface of gripper shoe in the middle part of the lower surface of gripper shoe, the middle part of column casing forms the needling for placing hydraulic prop;Being provided with reinforcement in gripper shoe, described reinforcement has several, and one of them reinforcement is provided with recovery holes.The end of each reinforcement is all connected with the side of column casing;Being additionally provided with multiple installing hole in described gripper shoe, installing hole has been inserted into multiple shoe tack.Above-mentioned a kind of hydraulic prop post footwear, gripper shoe are provided with sunk structure, when post footwear stress is excessive, gripper shoe can deformation buffer pressure, the sunk structure degree of depth diminishes, and gripper shoe the most constantly increases with the contact surface in coal seam, reduces and measures at the bottom of the brill of hydraulic prop post footwear.Being additionally provided with installing hole in gripper shoe, when taking out hydraulic prop post footwear, staff can reduce, by installing hole to the air-blowing of gripper shoe bottom, the difficulty taking out hydraulic prop post footwear.

Description

A kind of hydraulic prop post footwear
Technical field
This utility model relates to a kind of hydraulic prop post footwear, is specifically related to a kind of hydraulic prop post footwear.
Background technology
Hydraulic prop is one of facility more conventional in coal production, and the bottom of hydraulic prop is provided with post Footwear, for increasing the contact area of hydraulic prop and coal seam, measure at the bottom of the brill of regulation hydraulic prop.
The lower surface of the gripper shoe of existing hydraulic prop post footwear is flat, the contact surface one between post footwear and coal seam Fixed.When the post footwear stress of diverse location, owing to coal seam soft durometer is different, stress varies in size, and each post footwear stretch into the deep of coal seam Degree difference, the height causing different hydraulic prop is different, and the hydraulic prop that stress is bigger is easily bent or kills, multiple Hydraulic prop top by the easy lateral deviation of support member, easily cause security incident.
Utility model content
The problem that the change in depth in coal seam is bigger, this practicality is stretched into when stress difference in order to solve prior art center pillar footwear Novel offer one hydraulic prop post footwear.
A kind of hydraulic prop post footwear, including gripper shoe, form oriented gripper shoe center in the middle part of the lower surface of gripper shoe The sunk structure of protuberance, is provided with column casing in the middle part of the upper surface of gripper shoe, the middle part of column casing is formed for placing hydraulic prop Needling;Being provided with reinforcement in gripper shoe, the end of each reinforcement is all connected with the side of column casing;Also set in described gripper shoe It is equipped with multiple installing hole, in each installing hole, is inserted with shoe tack respectively.
Preferably, described reinforcement has several, and one of them reinforcement is provided with recovery holes.
This utility model compared with prior art, has the advantages that
Above-mentioned a kind of hydraulic prop post footwear, the lower surface of gripper shoe is provided with concave up sunk structure, when post footwear When stress is excessive or coal seam is really up to the mark, gripper shoe can deform, and the degree of depth of sunk structure diminishes, it is possible to compensator or trimmer pressure, gripper shoe with The contact surface in coal seam the most constantly increases, and reduces and measures at the bottom of the brill of hydraulic prop post footwear.It is additionally provided with installing hole in described gripper shoe, takes When going out hydraulic prop post footwear, staff can reduce take out hydraulic prop post footwear by installing hole to the air-blowing of gripper shoe bottom Difficulty, meanwhile, installing hole has been inserted into shoe tack, prevents hydraulic prop post footwear from moving, it is ensured that stablizing of hydraulic prop.
Being provided with multiple reinforcement in described gripper shoe, each reinforcement can increase the intensity of gripper shoe, prevent gripper shoe Damage.Can arrange recovery holes on one of them reinforcement, staff can be connected in recovery holes with silk thread, facilitates the later stage Reclaim hydraulic pressure prop.
Accompanying drawing explanation
Fig. 1 is the profile of a kind of hydraulic prop post footwear.
Fig. 2 is the top view of a kind of hydraulic prop post footwear.
1 gripper shoe;21 first reinforcements;22 second reinforcements;3 column casings;4 recovery holes;5 needlings;6 shoe tacks.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, this utility model is described in detail.
A kind of hydraulic prop post footwear, including gripper shoe 1, described gripper shoe can be square, the lower surface of gripper shoe 1 Middle part forms the sunk structure of oriented gripper shoe central elevation, is provided with column casing 3, in column casing 3 in the middle part of the upper surface of gripper shoe 1 Portion forms the needling 5 for placing hydraulic prop;Four the first reinforcements 21 and two the second reinforcements it are provided with in gripper shoe 1 22, the first reinforcement 21 extends to the edge of gripper shoe, and the second reinforcement 22 extends to the correspondence position, top at sunk structure edge Put, one of them second reinforcement 22 is provided with recovery holes 4.All sides with column casing 3, the end of each reinforcement are connected;Institute State and in gripper shoe 1, be additionally provided with multiple installing hole, in each installing hole, be inserted with shoe tack 6 respectively.
Above-mentioned a kind of hydraulic prop post footwear, the lower surface of gripper shoe 1 is provided with sunk structure, when post footwear stress is excessive Time, gripper shoe 1 can deform, and the sunk structure degree of depth diminishes, it is possible to compensator or trimmer pressure, and gripper shoe 1 is the most continuous with the contact surface in coal seam Increase, reduce and measure at the bottom of the brill of hydraulic prop post footwear.Being provided with multiple reinforcement in described gripper shoe 1, each reinforcement can increase The intensity of gripper shoe 1, prevents gripper shoe 1 from damaging.Installing hole it is additionally provided with in described gripper shoe 1, when taking out hydraulic prop post footwear, Staff can reduce, by installing hole to gripper shoe 1 bottom air-blowing, the difficulty taking out hydraulic prop post footwear, can on reinforcement To arrange recovery holes 4, staff can be connected in recovery holes 4 with silk thread, facilitates the later stage to reclaim hydraulic pressure prop.With Time, installing hole has been inserted into shoe tack 6, prevents hydraulic prop post footwear from moving, it is ensured that stablizing of hydraulic prop.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, Change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should Belong to protection domain of the present utility model.
