Description
Technical field
The utility model relates to a kind of coal and gas burst experiment equipment, relates in particular to coal and mash gas extrusion mold pressure frame.
Background technology
Though the combined action hypothesis is generally approved at coal and gas outburst mechanism research field, this hypothesis think coal and gas outstanding be result by the mechanical property combined action of terrestrial stress, gas pressure and coal, but the mechanism of action in each comfortable outstanding process of three factors is still undistinct.For further explaining the mechanism of action of three factors in the combined action hypothesis, Chinese scholars has successively been developed a series of coals and gas outburst simulation test device.Though these devices have been deepened the progress of coal and gas outburst mechanism to a certain extent, the outstanding coal sample size of ubiquity is less, the air inlet source is that " some inflation ", aspis immobilize, the aspis opening speed waits deficiency more slowly.2007, the Yin Guang of University Of Chongqing will, Xu Jiang, bright learn good fortune etc. on the basis of former achievements independent research big moulded coal and gas outburst simulation test platform, the size of outstanding coal sample is bigger in this test unit, realized the face aerification function of gas source of the gas, be used to explore the mechanism of action of combined action hypothesis, can carry out different gas pressures, coal and the gas outburst simulation test under the stress differently, realized coal and the omnidistance playback function of the outstanding process of gas by means of high-speed camera, obtained certain scientific payoffs in gas diaster prevention and control field.But, this device be by four groups of small-sized hydraulic lifting jack on the testing table on outstanding testing table to coal dust by the experiment parameter straight forming, not only operation is loaded down with trivial details for this mode, complicated operation, waste time and energy, easily cause small-sized lifting jack to damage, and be difficult for four groups of stress that hydraulic jack goes out are applied to fully and give prominence on the coal sample, cause that used outstanding coal sample has certain forming errors when testing.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of coal and mash gas extrusion mold pressure frame, to simplify the operation to the coal dust pre-molding.
The technical solution of the utility model is as follows: a kind of coal and mash gas extrusion mold pressure frame, comprise connecting link, entablature, pre-pressing mold, sill, lifting jack and support platform, wherein four vertical connecting links by the rectangular distribution, the upper end together support entablature of four connecting links, the bottom of this entablature is provided with pre-pressing mold; In the lower end of four connecting links sill is installed, the central authorities of this sill are provided with lifting jack, the push rod of described lifting jack straight up, and the upper end of push rod is fixed with support platform, this support platform be positioned at pre-pressing mold under.
In the utility model, the shape of pre-pressing mold size adapts with the inner chamber of outstanding mould.In the time of coal dust will being pressed the experiment parameter pre-molding, at first in outstanding mould, fill coal dust, to give prominence to mould with fork truck then is transported on the support platform, and make the uncovered of outstanding mould upper end over against pre-pressing mold, control the lifting jack action again, the outstanding mould of push rod drive of lifting jack is moved upward, along with the continuous rising of outstanding mould, pre-pressing mold embeds in the outstanding mould, coal dust can be compressed.The utility model is compared with straight forming on testing table, and not only operation is simple, processing ease, and locatees conveniently, time saving and energy saving, and good forming effect can effectively improve the efficient of coal dust pre-molding.
In order to make the utility model fixed, do not shake, be welded with supporting seat in the left and right sides of above-mentioned sill bottom, this supporting seat is fixedlyed connected with ground with nut by foot bolt.
For simplified structure, be convenient to install, the lower end of above-mentioned four connecting links is passed the through hole at place, four angles of sill respectively, by nut lock; The upper end of four connecting links is passed the through hole at place, four angles of entablature respectively, by nut lock.
For the ease of processing, above-mentioned pre-pressing mold is a rectangular structure.
Beneficial effect: the utility model is reasonable in design, enforcement is easy, simple to operate, convenient, the good reliability in location, and good forming effect can effectively improve the efficient of coal dust pre-molding.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model is made of parts such as connecting link 1, entablature 2, pre-pressing mold 3, sill 4, lifting jack 5, support platform 6, supporting seat 7, foot bolt 8 and nuts.Wherein four connecting links 1 vertically distribute by rectangle, and the lower end of four connecting links 1 is passed the through hole at place, 4 four angles of sill respectively, and the end face of sill 4 is spacing by the step surface on the connecting link 1, and the bottom surface of sill 4 is spacing by the nut 10 of locking on the sill 4.The left and right sides in sill 4 bottoms is welded with supporting seat 7, and this supporting seat 7 is connected with ground by forward and backward two foot bolt 8, by nut 9 lockings.
As can be known, the upper end of four connecting links 1 is passed the through hole at place, 2 four angles of entablature respectively from Fig. 1, Fig. 2, and the bottom surface of entablature 2 is spacing by the step surface on the connecting link 1, and the end face of entablature 2 is spacing by the nut 11 of locking on the entablature 2.Be fixed with pre-pressing mold 3 in the bottom of entablature 2, this pre-pressing mold 3 is a rectangular structure, and the shape size adapts with the inner chamber of outstanding mould.In the central authorities of described sill 4 lifting jack 5 is installed, the push rod 5a of lifting jack 5 straight up, and the upper end of push rod 5a is fixed with support platform 6, this support platform 6 be positioned at pre-pressing mold 3 under.The outstanding mould 12 usefulness fork trucks of filling coal dust are transported on the support platform 6, and make the uncovered of outstanding mould 12 upper ends over against pre-pressing mold 3, control lifting jack 5 actions then, the outstanding mould 12 of push rod 5a drive of lifting jack 5 is moved upward, continuous rising along with outstanding mould 12, pre-pressing mold 3 embeds in the outstanding mould 12, coal dust can be compressed.
