Description
Technical field
The utility model relates to a kind of coal petrography mash gas dynamic disaster analogue means special pressing plate sealing mechanism with the rectangle relief port.
Background technology
The right unstable failure of lab simulation coal containing methane gas petrosal process is one of research coal petrography mash gas dynamic disaster important means.At present, the main method of simulated experiment is to offer sealable relief port at airtight container, before the experiment with the moulded coal container of packing into, high pressure charges into adsorbable gas (CH4 or CO2), by external device (ED) to the moulded coal imposed load, the relief port throws open during experiment, and moulded coal and gas is ejection suddenly under load and hyperbar effect.Therefore, the shape of relief port, size, Sealing Technology are the key factors that influences experiment effect.For reaching sealing effectiveness, circle is adopted in the relief port more now, add silica gel sealing or adopt the tinfoil sealing with O shape circle, but the silica gel or the tin film encapsulation scheme operation that adopt at present is more, and spended time is long, and repeated workload is big after the seal failure.And colliery scene coal seam digging laneway mostly is trapezoidal or rectangle, therefore uses the simulation of circular relief port with on-the-spot actual inconsistent, can not simulate the dynamic disaster of rectangle or trapezoidal heading end.Simulated experiment adopts the rectangle relief port more to approach field engineering reality, can simulate the dynamic disaster of rectangle or trapezoidal heading end, but rectangle relief port greatest problem is corner's sealing difficulty, and therefore existing scheme multipurpose circular relief port is conveniently to reach sealing load.
The utility model content
The purpose of this utility model provides a kind of simple in structure, good sealing effect, the coal petrography mash gas dynamic disaster analogue means special pressing plate sealing mechanism of the rectangle relief port that bearing capacity is big.
For achieving the above object, the utility model adopts following technical scheme: a kind of coal petrography mash gas dynamic disaster analogue means rectangle relief port pressing plate sealing mechanism, the bearing plate and the square sprue that is arranged on the bearing plate back side that comprise vertical setting, an inclined-plane is each side established in the bearing plate front, two inclined-planes respectively towards rear, the left and right sides to extension, respectively be crimped with a relief panel on two inclined-planes, two relief panel all connect pressure apparatus.
Described pressure apparatus comprises the actuating cylinder of establishing cylinder piston in positioning framework and two, and actuating cylinder and cylinder piston all are horizontally disposed with and left and right directions extends, and two cylinder piston heads of two actuating cylinders are fixedlyed connected with two relief panel relatively and respectively; Sealing clamp and two relief panel all are positioned at positioning framework, and two actuating cylinders are arranged in respectively outside the positioning framework both sides, and two cylinder pistons of two actuating cylinders and positioning framework are pegged graft.
The border of square sprue is wound with rubber cushion, extends outside the square sprue around the bearing plate.
On the plate face of described relief panel ball is set, ball and corresponding bearing plate inclined-plane fit.
Because coal mine underground coal bed tunnel mostly is rectangle or trapezoidal, the utility model is the special pressing plate mechanism at the dynamic disaster analogue means with rectangle relief port, rubber cushion is adopted in sealing, and relief panel and inclined-plane crimping mutually, convert actuating cylinder thrust to pressure to seal gasket, realized quick and convenient sealing to the rectangle relief port, and because the interior hyperbar of pressure cylinder (having the rectangle relief port) is not to rubber cushion forward exert pressure (just each pressure is born by bearing plate), rubber cushion only bears anticyclonic side direction acting force, so good sealing effect, bearing capacity is big.On the plate face of relief panel ball is set, ball and corresponding bearing plate inclined-plane fit, and can reduce the friction force of relief panel on the bearing plate inclined-plane.

Embodiment
By Fig. 1-a kind of coal petrography mash gas dynamic disaster analogue means rectangle relief port pressing plate sealing mechanism shown in Figure 7, comprise sealing clamp 3, sealing clamp 3 comprises the bearing plate 10 of vertical setting and is arranged on the square sprue 9 at bearing plate 10 back sides, the border of square sprue 9 is wound with rubber cushion 7, extends outside the square sprue 9 around the bearing plate 10.An inclined-plane 8 is each side established in bearing plate 10 fronts, two inclined-planes 8 respectively towards rear, the left and right sides to extension, respectively be crimped with a relief panel 2 on two inclined-planes 8, relief panel 2 is consistent with inclined-plane 8 vergence directions of its crimping, the ball 6 of spherical shape is set on the corresponding plate face in described relief panel 2 and inclined-plane 8, ball 6 fits with corresponding bearing plate 10 inclined-planes 8, the groove of semicircle sphere can be set on the plate face of relief panel 2, after ball 6 is put into groove, but tool using beats the plate face of the relief panel 2 of groove border, make the shaped slightly distortion of groove at its plate face, then ball 6 can rotate in groove, also is fastened in the groove can not drop out.
Two relief panel 2 all connect pressure apparatus.Pressure apparatus is positioned at the place ahead in bearing plate 10 fronts, described pressure apparatus comprises the actuating cylinder 5 of establishing cylinder piston 4 in positioning framework 1 and two, actuating cylinder 5 and cylinder piston 4 all are horizontally disposed with and left and right directions extends, and two cylinder pistons, 4 heads of two actuating cylinders 5 are fixedlyed connected with two relief panel 2 relatively and respectively; Sealing clamp 3 and two relief panel 2 all are positioned at positioning framework 1, two actuating cylinder 5 and are arranged in respectively outside positioning framework 1 both sides, and two cylinder pistons 4 of two actuating cylinders 5 are pegged graft with positioning framework 1.
Before the experiment, at first square rubber cushion 7 is installed on the sealing clamp 3, what then sealing clamp 3 is placed in coal petrography mash gas dynamic disaster analogue means unloads 12 places, cylinder pressure cylinder body 11 rectangle relief ports, scrutiny, guarantee rubber cushion 7 four limits and unload cylinder pressure cylinder body 11 fluid-tight engagement, positioning framework 1 can directly be fixedly connected on and unload outside the cylinder pressure cylinder body 11, firmly withstands sealing clamp 3 with instrument (iron staff or screwdriver), starting the power air pump is actuating cylinder 5 and cylinder piston 4, and both sides relief panel 2 is closed.Relief panel 2 is closed the inclined-plane 8 of process sealing clamp 3 in the closed procedure, implements extruding forces by sealing clamp 3 to rubber cushion 7, reaches the purpose to relief port 12 sealings.At last, annotate high pressure gas, the check sealing effectiveness to cylinder body 11.Through experimental verification, this kind encapsulating method, maximum can be born the air pressure of 5MPa.
Certainly, the utility model is not limited to above-mentioned form, and fast pressure relief plate 2 can use electronic, but for the purpose of the safety, can only fill non-explosivity gas at cylinder body 11.
