Abstract
The utility model relates to the technical field of hydraulic supports and discloses a hydraulic support preventing rock burst. The hydraulic support preventing the rock burst comprises a left top beam (1), a right top beam (2), side bases (3), a middle stand column (4), side stand columns (5), and a middle base (6), wherein the left top beam (1) and the right top beam (2) are connected with each other in a hinged mode to form an upper arched support, a center position of the upper arched support is connected with the middle base (6) of a lower arched support through the middle stand column (4), two ends of the middle base (6) of the lower arched support are connected with the side bases (3), and the side bases (3) arranged at two sides of the lower arched support are respectively connected with two ends of the upper arched support through the side stand columns (5). The hydraulic support preventing the rock burst can reduce damages to a roadway through pressure resistance, buffering and pressure relief of the stand columns, can effectively reduce damages caused by the rock burst of a coal mine, and protects lives and properties of workers. In other words, the purpose of protecting the roadway is achieved through the pressure relief of stand column safety valves.
Description
Technical field
The utility model relates to the hydraulic support technical field, is particularly useful for a kind of protecting against shock ground hydraulic fluid pressure support that the bump mine more deeply, easily takes place working seam.
Background technology
Along with the continuous increase of mining depth, the bump accident in colliery is also more and more.Owing to the bump problem is very complicated, set up more realistic bump generation and the theory of destructive process both at home and abroad at present as yet, thereby the prediction of bump, forecast and control and incomplete.How frequently under special geology and the technical condition, improve production technique level, production efficiency, recovery ratio and output at bump, be a global technical barrier always, up to now, do not have good solution.
Summary of the invention
In order to overcome the deficiency in the background technology, the utility model provides a kind of protecting against shock ground hydraulic fluid to press support.Be moment according to bump, energy is huge, can only take to reduce pressure, the measure of step-down, on this basis and design premises, cushions to reach the purpose of erosion control by the resistance to compressions at different levels of back timber, base, column.
In order to realize the foregoing invention purpose, the utility model adopts technical scheme as follows:
A kind of protecting against shock ground hydraulic fluid is pressed support, comprise: left back timber 1, right back timber 2, limit base 3, central post 4, edge column 5, middle base 6, arch trestle on described left back timber 1 and the right back timber 2 hinged formations, the centre bit of last arch trestle links to each other with the middle base 6 of following arch trestle by central post 4, and described arch trestle is down linked to each other with limit base 3 by the two ends of middle base 6; The limit base 3 at following arch trestle two ends links to each other with the two ends of last arch trestle by edge column 5 respectively.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
A kind of protecting against shock ground hydraulic fluid is pressed support, can effectively reduce the destruction that coal mine rock burst brings.When bump came, the resistance to compression by column, buffering, release reduced the destruction to the tunnel, effectively protect workman's safety of life and property.Namely when reaching the column set pressure for safety valve, by the release of column safety valve, reach the purpose in protection tunnel.
The exploitation of the utility model protecting against shock hydraulic support can effectively improve lame advanced supporting intensity, reduces to impact the roadway deformation that brings, assurance equipment and personal safety.
Description of drawings
Fig. 1 is the structural representation that protecting against shock ground hydraulic fluid is pressed support;
Among the figure: 1, left back timber; 2, right back timber; , the limit base; 4, central post; 5, edge column; 6, middle base.
The specific embodiment
As shown in Figure 1, a kind of protecting against shock ground hydraulic fluid is pressed support, comprise: left back timber (1), right back timber (2), limit base (3), central post (4), edge column (5), middle base (6), arch trestle on described left back timber (1) and the hinged formation of right back timber (2), the centre bit of last arch trestle links to each other with the middle base (6) of following arch trestle by central post (4), and described arch trestle is down linked to each other with limit base (3) by the two ends of middle base (6); The limit base (3) at following arch trestle two ends links to each other with the two ends of last arch trestle by edge column (5) respectively.
Next interim when bump, moment can be broken out very macro-energy, when reaching way column set pressure for safety valve, by column safety valve automatically unloading, by the release of safety valve, reaches the purpose in protection tunnel.Be bump when coming, resistance to compression, buffering, release by column reduce the destruction to the tunnel, effectively protect workman's safety of life and property.
Claims (1)
1. a protecting against shock ground hydraulic fluid is pressed support, it is characterized in that: comprising: left back timber (1), right back timber (2), limit base (3), central post (4), edge column (5), middle base (6), arch trestle on described left back timber (1) and the hinged formation of right back timber (2), the centre bit of last arch trestle links to each other with the middle base (6) of following arch trestle by central post (4), and described arch trestle is down linked to each other with limit base (3) by the two ends of middle base (6); The limit base (3) at following arch trestle two ends links to each other with the two ends of last arch trestle by edge column (5) respectively.
