Technical Field

[0001] The invention relates to the technical field of mine air doors, in particular to a guide rail type linked synchronous pressure reducing mine air door. Background Art

[0002] Mine dampers are devices used to control airflow in underground tunnels of coal mines and other mines. They can reasonably distribute and adjust the ventilation volume of various areas underground to ensure the normal operation of the ventilation system. At the same time, they can also isolate different areas, prevent wind turbulence, and reduce air leakage. They are an important part of the safety and stability of the underground working environment. Mine dampers are generally divided into manual ordinary dampers, mechanically driven guide rail linkage synchronous pressure relief dampers and two-way pressureless dampers.

[0003] In the existing technology, in the actual use of the existing mine rail-type linked synchronous pressure-reducing damper, although the opening degree of the damper door plate can be easily adjusted by electric mechanical drive, that is, the purpose of adjusting the pressure is achieved by controlling the cross-sectional area of ​​air circulation, but there is no mechanism for assisting the opening of the damper door plate. That is, when the motor in the damper driven by electric machinery is suddenly damaged during use and the damper door plate needs to be opened urgently to allow the vehicle to pass, the damper door plate without a handle cannot be easily opened, and a new drive motor cannot be found in time as a drive device, which results in the inability to work normally in the mine, which reduces the use effect of the rail-type linked synchronous pressure-reducing damper for mines, and also reduces the use efficiency of the rail-type linked synchronous pressure-reducing damper for mines.

At this time, the damper door plate that is not equipped with a handle cannot be easily opened, and a new drive motor cannot be found in time as a drive device, which results in the inability to carry out normal work in the mine, which not only reduces the use effect of the rail-type linked synchronous pressure-reducing mine damper, but also reduces the use efficiency of the rail-type linked synchronous pressure-reducing mine damper.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0019] 2. The present invention then utilizes the cooperation of one of the round tubes, the hand screw, one of the round rods and the hollow plate to adjust the position of the first winding drum, and allows the first winding drum after the position is adjusted to be squeezed and fixed, and then utilizes the cooperation of the first steel wire rope, the first connecting piece, the bolt, the first winding drum, the first bearing, the other round rod, the third bearing, the second steel wire rope and the second winding drum connected thereto to achieve the rotation of the other round tube, and then utilizes the cooperation of another round tube, two auxiliary gears, chains, two hollow blocks and the fourth bearing to achieve the rotation of the main gear fixed on the rotating rod, that is, the rotating main gear can utilize the cooperation of the main gear meshing therewith, the single-head screw, the sliding hole, the air outlet door frame, the moving wheel, the auxiliary wheel and the sliding groove to achieve the movement of the two air door panels in opposite directions until the two air door panels are completely moved into the corresponding storage grooves.

At this time, the started motor 115 will directly drive the corresponding main gear 112 to rotate under the cooperation of the two hollow blocks 113, the fourth bearing and the rotating rod 114, and the rotating main gear 112 will directly drive the single-head screw 105 connected to it to rotate under the cooperation of the main gear 112 meshing with it, and at the same time, the rotating single-head screw 105 will also drive the other single-head screw 105 connected to it to rotate. When the two single-head screws 105 rotate at the same time, this The two single-head screws 105 rotating at the same time will directly make the two sets of moving wheels 106 move in opposite directions with the cooperation of the sliding hole 104, and the two sets of moving wheels 106 moving in opposite directions will directly move to the corresponding storage slots 102 with the cooperation of the corresponding sliding slots 108, the air outlet door frame 101 and the corresponding two auxiliary wheels 110. When the distance between the opposite sides of the two air door panels 109 reaches a suitable length, the controller 116 is directly used to pause the motor 115. At this time, the distance between the two air door panels 109 is used to adjust the airflow pressure in the mine environment, thereby ensuring the stability and safety of the ventilation system. When it is necessary to fine-tune the airflow pressure inside the mine, it is necessary to ensure that the opposite sides of the two air door panels 109 are in contact with each other. , then loosen the two hand-tightening bolts 127 in turn, then manually push the moving block 125 toward the inner wall direction of the damper plate 124, and then let the moving block 125 move on the damper plate 124. At this time, the moving moving block 125 will directly drive the two hand-tightening bolts 127 and the two anti-skid pads 128 connected thereto to move with the cooperation of the two limiting holes 126. When the moving block 125 moves to the appropriate position, the two hand-tightening bolts 127 are directly tightened again, that is, the cooperation of the hand-tightening bolts 127, the anti-skid pads 128, the limiting holes 126 and the damper plate 124 is used to squeeze and fix the moved moving block 125, that is, the cooperation of the moving block 125 and the damper plate 124 is used to achieve fine-tuning of the airflow pressure inside the mine tunnel. When the motor 115 is damaged and the damper door plate 109 needs to be opened urgently to allow the vehicle to pass, the first connecting member 209 with bolts and nuts is first removed from the inside of the placement hole 208, and then the first connecting member 209 with bolts and nuts is passed through the threading hole 218. At this time, the moving first connecting member 209 will drive the first steel wire rope 210 connected thereto to move, and then the second connecting member 217 connected to the corresponding second steel wire rope 215 on the corresponding second winding drum 212 (corresponding to the two damper door plates 109 moving in opposite directions) is removed from the inside of the card slot 216, and then the first connecting member 209 and the second connecting member 217 are fixed together by the bolts and nuts on the moving first connecting member 209.Then loosen the two hand screws 205. When the two hand screws 205 are loosened, one of the round tubes 202 can be moved directly. At this time, one of the moved round tubes 202 will drive the hollow plate 204 and the first winding drum 203 connected thereto to move at the same time. When the first winding drum 203 moves to a suitable position, tighten the two hand screws 205 again. When the two hand screws 205 are tightened, the moved round tube 202 can be fixed. At this time, the first wire rope 210 is placed inside the second winding drum 212, and then the output end of the motor 115 is separated from one end of the rotating rod 114. Then the motor 115 is removed from the top position of the inner wall of the clamping end on one side of the tuyere door frame 101, and then the first wire rope 210 is pulled. 0, the other end of the moving first wire rope 210 will directly rotate the corresponding second wire rope 212 under the cooperation of the first connecting member 209, the second connecting member 217, the bolt, the nut, the first winding drum 203, the first bearing, the other round tube 202, the other round rod 201 and the second wire rope 215, and realize the unwinding of the second wire rope 215 from the corresponding second winding drum 212, and at the same time, the second winding drum 212 without removing the first connecting member 209 will also rotate. When the other round tube 202 rotates, the rotating other round tube 202 will also drive the auxiliary gear 213 connected thereto to rotate, and the rotating auxiliary gear 213 will rotate the auxiliary gear 213 on the chain and the rotating rod 114. 13, the two single-headed screws 105 are driven to rotate simultaneously. When the two single-headed screws 105 rotate simultaneously, the two rotating single-headed screws 105 will directly cooperate with the sliding hole 104 to allow the two sets of moving wheels 106 to move in opposite directions, and the two sets of moving wheels 106 moving in opposite directions will directly cooperate with the corresponding sliding groove 108, the air outlet door frame 101 and the corresponding two auxiliary wheels 110 to move to the corresponding storage groove 102 respectively. When the two air door panels 109 are moved to the point where they cannot move, the pulling operation of the first wire rope 210 is stopped, and the vehicle can pass through the air door. When the air door needs to be closed, the first connecting piece 209 connected to the first wire rope 210 is connected to the first connecting piece 209 that has not been pulled from the second winding drum 2 12, the second connecting piece 217 removed from the inner part of the upper card slot 216 is connected together, and then the upper output operation steps are repeated to reset the two damper door plates 109 to the initial position, and at the same time, the second steel wire rope 215 previously unwound from the inner part of the second winding drum 212 is also wound back. When the two damper door plates 109 are reset to the initial position, the second steel wire rope 215 previously unwound from the inner part of the second winding drum 212 is also completely wound back. At this time, the second connecting piece 217 connected to the second steel wire rope 215 is fixed to the inner part of the corresponding card slot 216, and then the first steel wire rope 210 is tied to one of the round rods 201. After the new motor 115 is replaced, the first connecting piece 209 and the second connecting piece 217 are separated.Then, the first connecting member 209 is reset and placed back into the placement hole 208.

[0049] Among them, the first bearing, the second bearing, the third bearing, the fourth bearing and the chain are all commonly used parts in reality;

[0050] The size of the first connecting member 209 is the same as that of the second connecting member 217, and bolts and nuts are disposed inside the two through holes on the second connecting member 217;
