[0002] In coal mining, as the mining face advances, the upper corner of the mining face is close to the coal wall and the goaf side, the wind speed is low, and the local area is in a vortex state. This vortex makes it difficult for the gas gushing out of the goaf to enter the main wind flow. In order to prevent gas gushing out, it is necessary to construct a closed wall to close the upper and lower corners to prevent gas gushing out and cause gas accidents. At the same time, the closed wall is required to be well sealed after construction to ensure the gas extraction effect of the upper corner, so it is necessary to use an inflatable gas stack for sealing.

[0003] The existing inflatable air stacks are usually connected and fixed with multiple sets of bolts to ensure the stable connection between the air stacks.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a plastic coated cloth inflatable gas stack, comprising a base 1, a gas stack body 2 is fixedly connected to the top of the base 1, a connecting groove 4 is provided on one side of the outside of the base 1, two limiting grooves 6 are provided on the side of the inside of the base 1 close to the connecting groove 4, a spring 7 is fixedly connected to the inside of the limiting groove 6, the other end of the spring 7 is fixedly connected to a limiting block 8, a pull rod 9 is fixedly connected to one side of the limiting block 8, a clamping block 10 is fixedly connected to the other side of the limiting block 8, a connecting block 5 is fixedly connected to the other side of the outside of the base 1, clamping grooves 14 are provided at both ends of the connecting block 5, the inside of the connecting groove 4 is slidably connected to the outside of the connecting block 5, and the inside of the clamping groove 14 is slidably connected to the outside of the clamping block 10 on the adjacent side.

[0024] Specifically, through the connection between the base 1 and the gas stack body 2, the gas can be rushed into the interior of the gas stack body 2, and the good sealing can prevent internal gas leakage, and by pulling the pull rings 15 on both sides of the base 1, the pull rod 9 can be driven to move, and then the pull rod 9 drives the limit block 8 to move inside the limit groove 6, so that the limit block 8 drives the clamping block 10 to move toward the inside of the limit groove 6. At this time, the connecting block 5 on the outside of another inflatable gas stack is inserted into the inside of the connecting groove 4. The spring 7 can rebound after the pull rod 9 is released, pushing the limit block 8 to move, so that the clamping block 10 is inserted into the inside of the clamping groove 14 and engages, thereby realizing the assembly and splicing of the two gas stacks. The installation speed is improved by the clamping method, so that workers can complete quick assembly without the aid of tools, thereby improving the convenience of installation and facilitating maintenance.

[0025] Reference Figure 4The supporting assembly includes a telescopic rod 11, the bottom end of the telescopic rod 11 is fixedly connected to the top of the base 1, the top of the telescopic rod 11 is fixedly connected to a protective pad 12, the top of the protective pad 12 is fixedly connected to the inner top wall of the air stack body 2, and the outer sleeve of the telescopic rod 11 is provided with a spring 13, one end of the spring 13 is fixedly connected to the bottom of the protective pad 12, and the other end of the top of the spring 13 is fixedly connected to the top of the base 1.

[0026] Specifically, by connecting the protective pad 12 to the inner top wall of the air stack body 2 and fixing the telescopic rod 11 to the protective pad 12, the telescopic rod 11 can be fixed to the top of the base 1, so that the spring 2 13 can push the protective pad 12 to move and support it. By fixing the two ends of the spring 2 13 respectively through the protective pad 12 and the base 1, the spring 2 13 can maintain stable contraction.

[0027] Reference Figure 3 The outside of the limit block 8 is slidably connected to the inside of the limit groove 6, and the spring 7 is sleeved on the outside of the pull rod 9. One end of the pull rod 9 extends to the outside of the base 1 and is fixedly connected with a pull ring 15.

[0028] Specifically, the movement of the limit block 8 can be limited by the limit groove 6 to keep it moving horizontally, and the pull rod 9 can keep the spring 7 stably contracted, thereby maintaining the stable operation of the structure, and the pull ring 15 can facilitate pulling the pull rod 9, thereby realizing the installation and splicing of the air stack.

[0029] Reference Figure 1 The middle part of the front side of the base 1 is fixedly connected with an inflation port 3. The outer layer of the air stack body 2 can be made of rubber, polyvinyl chloride and other materials, and the inner layer of the air stack body 2 can be made of nylon, polyester and other materials.

[0030] Specifically, the gas stack body 2 can be inflated through the inflation port 3, so that the gas stack plays a protective role. Using rubber, polyvinyl chloride and other materials as the outer layer of the gas stack body 2, and nylon, polyester and other materials as the inner layer of the gas stack body 2 can enhance the wear resistance of the gas stack and increase the service life of the gas stack.

[0031] Working principle: When assembling the gas stack, first pull the pull rings 15 on both sides of the base 1 so that the pull rings 15 drive the pull rods 9 to move, and then the limit block 8 moves inside the limit groove 6. At this time, the limit block 8 will drive the card block 10 to move toward the inside of the limit groove 6, and apply pressure to the spring 17 to shrink it, then insert the connecting block 5 outside the other inflatable gas stack into the inside of the connecting groove 4 opened on one side of the current gas stack, and then release the pull ring 15 to allow the spring 17 to rebound, thereby pushing the limit block 8 to move, so that the card block 10 can be inserted into the inside of the card groove 14 opened on the connecting block 5, thereby realizing the assembly and splicing of the two gas stacks. The installation speed is improved by the card connection method, so that workers can complete the quick assembly without the aid of tools, which improves the convenience of installation and facilitates maintenance. At the same time, through the multiple supporting components inside the gas stack body 2, the gas stack body 2 can provide supporting force after being filled with air, so that the pressure resistance of the gas stack is enhanced.
