[0002] In the coal gas storage and transportation system, dry-type gas holder occupies an important position with its unique advantages. Dry-type gas holder is a large container equipment for storing and regulating industrial gas (such as blast furnace gas, coke oven gas, etc.), and its inside realizes the storage and release of coal gas through the up-down movement of the piston. Compared with wet-type gas holder, dry-type gas holder has the advantages of compact structure, small land occupation, simple maintenance and long service life, and has been widely used in steel, chemical, electric power and other industries.
[0003] The piston of dry-type gas holder is one of its core components, which is usually formed by connecting multiple truss units through connecting pieces to form a frame, and a layer of sealing film is covered on its surface to constitute a complete sealing structure. The piston moves up and down in the gas holder to regulate the pressure of the gas, store and release the gas. The sealing property and stability of the piston are crucial for the safe operation of the gas holder.
[0004] However, in the prior art, the connection between the truss units is usually achieved by traditional bolt and nut connection. Although this connection method has certain reliability and stability, the bolt and nut connection needs to be threaded through the hole one by one and tightened in the actual construction process, which is tedious and time-consuming, seriously affecting the construction efficiency. At the same time, when disassembly and maintenance are needed, the bolt and nut connection needs to be operated in reverse, and the disassembly process is also tedious. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION
[0019] The technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0020] Embodiment 1
[0021] In order to quickly disassemble and assemble the truss units 1, thereby quickly realizing the construction of the piston truss and improving the construction efficiency. Referring to Figures 1 to 5 The embodiment provides a piston truss ground assembly tire membrane device, which comprises a plurality of splicable truss units 1, each truss unit 1 is provided with two clamping rings 2 on a single side, and the opposite side is provided with a connection ring 3 matched with the clamping ring 2, and the connection ring 3 is provided with a clamping groove 301 on the side surface, which can be embedded with the clamping ring 2. When the adjacent truss units 1 are connected, the clamping ring 2 is embedded into the clamping groove 301 of the corresponding connection ring 3 to realize preliminary positioning.
[0022] A cylindrical connecting column 4 is inserted into the through hole of the connecting ring 3 and the clamping ring 2, and an axial sliding pull rod 5 is arranged in the connecting column 4. The top end of the pull rod 5 extends to the outside of the connecting column 4 and is connected with an operating handle 501, and a fixed block 6 is further arranged on the pull rod 5 and is sleeved with a vertical guide column 7 connected in the connecting column 4, and the fixed block 6 and the top surface of the connecting column 4 are elastically supported by a spring 8. The lower part of the connecting column 4 is provided with a radial through slot 402 distributed in a staggered manner with the pull rod 5, and two transversely sliding wedge-shaped clamping plates 10 are symmetrically arranged in the slot, and the top of the wedge-shaped clamping plate 10 is connected with the connecting column 4 through a horizontal guide column 11, and a spring 12 is arranged between the two. In particular, the bottom end of the pull rod 5 is fixed with a clamping ring 9 with an inclined surface, and the angle of the inclined surface is completely matched with the inclined surface of the wedge-shaped clamping plate 10.
[0023] When assembling, the operator pulls the handle 501 to drive the clamping ring 9 to move upward, and the wedge-shaped clamping plate 10 is retracted into the connecting column 4 by extrusion through the inclined surface and then inserted into the through hole of the combined unit. When the pressing handle 401 at the top of the connecting column 4 contacts the upper surface of the connecting ring 3, the handle 501 is released to reset the pull rod 5 driven by the first compression spring, the clamping ring 9 moves downward to release the constraint on the wedge-shaped clamping plate 10, and the second compression spring pushes the wedge-shaped clamping plate 10 out of the through slot 402, so that the wedge-shaped clamping plate 10 abuts against the inner wall of the through slot 402 and the lower surface of the connecting ring 3 to form a bidirectional locking, and the assembly of the piston truss is completed. After the piston truss is assembled, the sealing film 15 is fixed on the surface of the piston truss to form a complete piston. When disassembling, the reverse operation can release the locking to realize the quick disassembly without tools.
[0024] The truss unit 1 body is composed of inclined vertical frames 101 with a wide outer width and a narrow inner width, and a stable frame is formed between the vertical frames 101 through horizontal frames 102 and reinforcing rods 103. In order to further enhance the synchronicity of the wedge-shaped clamping plates 10, the middle parts of the two clamping plates are connected through the telescopic column 13 with the spring 14, so as to ensure the symmetry and stability of the clamping action.
[0025] By combining mechanical linkage with elastic reset, the efficiency of truss assembly is significantly improved, and the operation process does not need auxiliary tools, so that the quick disassembly of the truss units 1 is realized, thereby realizing the construction of the piston truss quickly and improving the construction efficiency.
[0026] The preferred embodiments disclosed above are only used to help describe the utility model. The preferred embodiments do not describe all the details, and the utility model is not limited to the specific implementation manner. Obviously, according to the content of the specification, many modifications and changes can be made.
