As an embodiment of the invention, an annular groove 43 is formed in the middle of the sliding chute 4, a sliding cylinder 35 is connected in the sliding chute 4 in a sliding manner, a convex ring 36 is fixedly connected to the position, corresponding to the annular groove 43, of the periphery of the sliding cylinder 35, and the convex ring 36 is connected with the annular groove 43 in a sliding manner; a sliding hole 37 is formed in the sliding barrel 35, a shaft sleeve 38 is sleeved in the sliding hole 37, and the first inserted rod 5 penetrates through the shaft sleeve 38 and is connected with the shaft sleeve 38 in a sliding manner; a circular ring 39 fixedly connected with the periphery of the shaft sleeve 38 is slidably connected with the sliding hole 37, and the top of the circular ring 39 is fixedly connected with a group of springs; through slide cartridge 35 cooperation axle sleeve 38 for door plant 2 is in the installation, insert the jack that corresponds the position in the swing arm 10 after aligning with last swing arm 10 earlier No. two inserted bars 11, later remove an inserted bar 5 and be close to axle sleeve 38, later upwards mention axle sleeve 38, make an inserted bar 5 release axle sleeve 38 after aligning with axle sleeve 38, make axle sleeve 38 cover in the 5 peripheries of an inserted bar, and then avoid the installation degree of difficulty that an inserted bar 5 aligns simultaneously with No. two inserted bars 11, further improve door plant 2's installation effectiveness.

As an embodiment of the present invention, a chamfer 40 is formed at the bottom of the shaft sleeve 38, a sealing groove is formed in the shaft sleeve 38 above the chamfer 40, a sealing ring 41 is fixedly connected in the sealing groove, and lubricating oil is filled in a gap between the first plunger 5 above the sealing ring 41 and the shaft sleeve 38; as to sealing washer 41 lower part through chamfer 40 for an inserted bar 5 is close to and contacts chamfer 40 back, guide an inserted bar 5 and insert the axle sleeve 38 fast, further reduce the degree of difficulty of aliging of an inserted bar 5, and simultaneously, the sealing washer 41 that is located chamfer 40 upper portion can be sealed axle sleeve 38 after an inserted bar 5 inserts axle sleeve 38, reduce the damage of colliding with of an inserted bar 5 to sealing washer 41, further guarantee the good lubrication between an inserted bar 5 and axle sleeve 38, reduce the leakage of lubricating oil.

As an embodiment of the present invention, an oil bag 42 is hermetically connected to the top of the shaft sleeve 38, and viscous lubricating oil is filled in the oil bag 42; a certain amount of lubricating oil is stored by matching the oil bag 42 with the sealing ring 41, so that the lubricating time between the first inserted rod 5 and the shaft sleeve 38 is prolonged, the abrasion of the shaft sleeve 38 is reduced, and the maintenance interval time is prolonged.

As an embodiment of the invention, the hydraulic oil filled in the first oil cylinder 14 is wear-resistant hydraulic oil, the first oil cylinder 14 is communicated with the second oil cylinder 17 through a branch pipe, and the branch pipe is fixedly connected with a pressure release valve; through branch cooperation relief valve, carry out the pressure release to a hydro-cylinder 14 fast, and then further increase door plant 2 and lower swing arm 12's dismantlement efficiency.

During operation, the first inserted bar 5 and the second inserted bar 11 are respectively inserted into the insertion holes in the sliding groove 4 and the upper swing arm 10, then the lower part of the door panel 2 is moved, the conical part is aligned with the through hole 16 on the lower swing arm 12, then the worm 22 is rotated, and the worm wheel 21 is driven to rotate, so that the worm wheel 21 drives the push rod 19 in threaded connection with the worm wheel 21 to move and extrude the second piston rod 18, the first piston rod 15 is further driven to extend out to fix the lower swing arm 12, the installation efficiency of the door panel 2 is increased, and meanwhile, the stable connection of the lower swing arm 12 and the door panel 2 is ensured through the self-locking effect of the worm wheel 21 and the worm; when the door plate 2 needs to be disassembled, the worm 22 is rotated in the opposite direction, so that the double-swing door can be conveniently and rapidly disassembled, the disassembling and maintaining efficiency of the double-swing door is improved, and the labor intensity of maintenance personnel is reduced; in the process that the worm 22 rotates reversely and the first piston rod 15 is folded upwards, the worm wheel 21 drives the winding roller 31 to tighten the steel rope 30, so that the steel rope 30 drives the rotating shaft 28 to rotate, the supporting leg 24 is pushed out downwards in cooperation with the inclined surface 26 and the second rotating pin 27, so that the small wheel 25 contacts the ground and supports the door panel 2, the separation speed between the lower swing arm 12 and the first piston is further increased, the labor intensity when the door panel 2 is moved is reduced, and the disassembly efficiency of the double-swing door is further increased; when the steel rope 30 is released through the winding roller 31, the steel rope 30 continuously rotates the rotating shaft 28 and the support legs 24 are upwards retracted, the steel rope 30 is wound on the periphery of the rotating shaft 28, the air bag 32 is further extruded, air in the air bag 32 is compressed and then is sprayed out from the inclined holes 33, the small wheel 25 is further cleaned, and the influence of sand and sand impurities on the normal movement of the small wheel 25 and the support rods is reduced; the cloth belt 34 is spirally wound on the periphery of the air bag 32, so that the extrusion area of the air bag 32 is increased, the exhaust volume of the inclined hole 33 is increased, the impact force and the purging time of compressed air sprayed out of the inclined hole 33 are further increased, and the influence of silt impurities on the normal movement of the small wheel 25 and the support rod is further reduced; through the matching of the sliding cylinder 35 and the shaft sleeve 38, in the installation process of the door panel 2, the second inserted bar 11 is aligned with the upper swing arm 10 and then inserted into the insertion hole at the corresponding position in the upper swing arm 10, then the first inserted bar 5 is moved to be close to the shaft sleeve 38, then the shaft sleeve 38 is lifted upwards, the shaft sleeve 38 is released after the first inserted bar 5 is aligned with the shaft sleeve 38, the shaft sleeve 38 is sleeved on the periphery of the first inserted bar 5, the installation difficulty that the first inserted bar 5 and the second inserted bar 11 are aligned at the same time is further avoided, and the installation efficiency of the door panel 2 is further improved; the lower part of the sealing ring 41 is arranged through the chamfer 40, so that after the first inserted rod 5 is close to and contacts the chamfer 40, the first inserted rod 5 is guided to be rapidly inserted into the shaft sleeve 38, the alignment difficulty of the first inserted rod 5 is further reduced, meanwhile, the sealing ring 41 positioned on the upper part of the chamfer 40 can seal the shaft sleeve 38 after the first inserted rod 5 is inserted into the shaft sleeve 38, the collision damage of the first inserted rod 5 on the sealing ring 41 is reduced, the good lubrication between the first inserted rod 5 and the shaft sleeve 38 is further ensured, and the leakage of lubricating oil is reduced; a certain amount of lubricating oil is stored by matching the oil bag 42 with the sealing ring 41, so that the lubricating time between the first inserted rod 5 and the shaft sleeve 38 is prolonged, the abrasion of the shaft sleeve 38 is reduced, and the maintenance interval time is prolonged; through branch cooperation relief valve, carry out the pressure release to a hydro-cylinder 14 fast, and then further increase door plant 2 and lower swing arm 12's dismantlement efficiency.
