DETAILED DESCRIPTION
[0014] The utility model will be further described in detail in combination with the drawings and specific embodiments.
[0015] As Figs. 1-3The gas detection device for coal mining is shown, which comprises a support beam 1, support columns 2 and a support plate 3. The support beam 1 is composed of the support columns 2 at the upper and lower parts and the support plate 3 at the middle part. The diameter of the support column 2 is greater than the thickness of the support plate 3. The support beam 1 is slidably connected with a plurality of support members 4 at the left and right sides. The support member 4 comprises a ceiling suction seat 5. The ceiling suction seat 5 is penetrated by mounting holes 6 for mounting and fastening. The left support seat 7 is mounted at the left part of the support beam 1. The right support seat 8 is mounted at the right part of the support beam 1. The clamping mechanism 9 is mounted at the upper part of the left support seat 7 and the right support seat 8, respectively. The clamping mechanism 9 comprises two auxiliary clamping plates 10 and two adjusting bolts 11. The adjusting bolt 11 is horizontally rotatably connected with the auxiliary clamping plate 10. The adjusting bolt 11 is threadedly connected with the left support seat 7 and the right support seat 8. The two auxiliary clamping plates 10 of the clamping mechanism 9 are tightly pressed at the front and rear ends of the support plate 3, respectively. The air suction pipe 12 is fixed to the left support seat 7. The air pump 13 and the gas detector 14 are fixed to the bottom end of the right support seat 8. The air suction end of the air pump 13 is communicated with the air suction pipe 12 through the hose 15. The air exhaust end of the air pump 13 is communicated with the gas detector 14. The sound and light alarm 16 is fixed to the bottom end of the gas detector 14. The air pump 13, the gas detector 14 and the sound and light alarm 16 are electrically connected. The gas detector 14 is connected with the power supply outside.
[0016] When in use, the ceiling suction seat 5 is fixed to the top end of the mine tunnel by the expansion screws and other fasteners. The left support seat 7 and the right support seat 8 are spaced at a certain distance, so that the air suction pipe 12 is located in the limited area and the gas detector 14 is located outside the limited area. Then the air in the limited area can be sucked by the air pump 13 and delivered to the gas detector 14 for detection. When there is flammable and explosive gas, the sound and light alarm 16 will alarm. When the gas detector 14 needs to be repaired or moved, the auxiliary clamping plate 10 can be contacted by loosening the adjusting bolt 11 to clamp the support plate 3, so that the right support seat 8 and the gas detector 14 are taken down together. When the position of the air suction pipe 12 and the gas detector 14 relative to the outside needs to be adjusted, on the one hand, the relative position of the clamping mechanism 9 relative to the support beam 1 can be adjusted, and on the other hand, the support beam 1 can be slid left and right along the support member 4, which is convenient and fast.
[0017] The support beam 1 is made of rubber. The helical springs 17 are respectively wrapped and fixed in the two support columns 2. The helical springs 17 always have a tendency to keep straight under the action of their own elastic force.
[0018] Further, the support beam 1 of this structure can be conveniently bent in the horizontal direction and has a tendency to recover, which is convenient for adapting to the curved mine tunnel.
[0019] The support piece 4 further comprises a main clamping plate 18, the front lower part and the rear lower part of the ceiling suction base 5 are rotationally connected with the main clamping plate 18, the ceiling suction base 5 is connected with the support plate 3 through the two main clamping plates 18 at the bottom of the ceiling suction base 5 to realize left and right sliding connection, the number of the support piece 4 is two, and the support beam 1 can swing left and right through cooperation of the main clamping plate 18 and the support plate 3.
[0020] Further, through cooperation of the two support pieces 4 and the rotation connection between the main clamping plate 18 and the ceiling suction base 5, the inclined mine tunnel top wall and the inclined installation environment can be adapted, that is, the support beam 1 is horizontal or is inclined downward to the left or to the right after installation.
[0021] The main clamping plate 18 and the auxiliary clamping plate 10 are each provided with an arc-shaped groove 19 capable of cooperating with the upper and lower support columns 2 of the support beam 1.
[0022] Further, cooperation of the arc-shaped groove 19 and the support column 2 can reduce wear of the main clamping plate 18 and the auxiliary clamping plate 10 on the support column 2 in the up and down direction, and reduce the probability of accidental disconnection of the support beam 1 in the up and down direction.
[0023] The above is the preferred embodiment of the present application, and for ordinary skilled in the art, according to the teaching of the present application, the change, modification, replacement and transformation of the embodiment without departing from the principle and spirit of the present application still fall within the protection scope of the present application.
