Abstract
A single body hydraulic support capable of automatically alarming aims at resolving the problem that coal mine resource safety mining and life safety of people are severely affected by the fact that coal and rock stress continuously increases with gradually increase of coal mine resource mining depth, and degree of damage to the roadway becomes increasingly severe. The single body hydraulic support capable of automatically alarming comprises a single body hydraulic support body (1) and a pressure alarming box (2) connected with the top end of the single body hydraulic support body. The single body hydraulic support is used for single body hydraulic support alarming in coal mines.
Description
Technical field:
the utility model relates to a kind of automatic warning monomer hydraulic support.
Background technology:
along with the increase day by day of the colliery resource exploitation degree of depth, coal petrography stress constantly increases, and is also more and more serious to the roadway destruction degree, has a strong impact on colliery resource security exploitation and people's life safety.At present, mostly the monomer supporting that home and abroad colliery uses is hydraulic prop, and the monomer hydraulic support all uses the piston type know-why like this, and when support ran into working resistance, oil cylinder may produce elastic expansion.When the pressure that bears when hydraulic prop reaches the pressure limit that support bears, be prone to cause the cylinder body spalling, cause the tunnel to collapse and personnel casualty accidents.
Summary of the invention:
The purpose of
the utility model provides the automatic warning monomer hydraulic support that can report to the police automatically when a kind of pressure that bears when the monomer hydraulic support reaches the pressure limit that it bears soon.
Above-mentioned purpose realizes through following technical scheme:
a kind of automatic warning monomer hydraulic support, its composition comprises: the monomer hydraulic support, described monomer hydraulic pressure cantilever tip connects the pressure alarm box.
described automatic warning monomer hydraulic support; Described pressure alarm box comprises box body; In the described box body power supply is housed, described power supply connects alarm, and described alarm connects pressure sensor; Described pressure sensor connects described power supply, connects through lead between described power supply, described alarm and the described pressure sensor.
Beneficial effect:
1. the utility model is simple in structure, cost is low, it is effective to be quick on the draw, to report to the police
, well protective cradle.
Automatic alarm can be carried out when 2. the pressure that bears when the monomer hydraulic support of the utility model reaches the pressure limit that it bears soon in
, and the staff has effectively prevented the spalling of cylinder body between can in time handling.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is structural representations of pressure alarm box in the accompanying drawing 1.
The specific embodiment:
Embodiment 1:
a kind of automatic warning monomer hydraulic support, its composition comprises: monomer hydraulic support 1, described monomer hydraulic pressure cantilever tip connects pressure alarm box 2.
Embodiment 2:
Claims (2)
1. automatic warning monomer hydraulic support, its composition comprises: the monomer hydraulic support is characterized in that: described monomer hydraulic pressure cantilever tip connects the pressure alarm box.
2. automatic warning monomer hydraulic support according to claim 1; It is characterized in that: described pressure alarm box comprises box body; In the described box body power supply is housed, described power supply connects alarm, and described alarm connects pressure sensor; Described pressure sensor connects described power supply, connects through lead between described power supply, described alarm and the described pressure sensor.
