Specifically, before strengthening the natural gas pipeline, the lower clamping device 5 can be placed at the lower part of the natural gas pipeline to be strengthened, then the upper clamping device 7 is placed at the upper end of the lower clamping device 5, so that the lower clamping device 5 and the upper clamping device 7 are sleeved outside the natural gas pipeline, and then the lower clamping device 5 and the upper clamping device 7 are driven by the pushing device 4 to clamp and fix the natural gas pipeline.
Before reinforcing the natural gas pipeline, the lower clamping device 5 and the upper clamping device 7 can be sleeved on the outer surface of the natural gas pipeline so that other mechanisms drive the lower clamping device 5 and the upper clamping device 7 to clamp and fix, as shown in fig. 3, the lower clamping device 5 comprises a first limiting shell 51, fixing holes 511 are formed in two sides of the upper end of the first limiting shell 51, fixing hook plates 52 are arranged on two sides of the upper end of the inner cavity of the first limiting shell 51, pulling plates 521 are arranged on one sides, away from each other, of the outer surfaces of the two fixing hook plates 52, one ends, away from each other, of the two pulling plates 521 are extended to the outer portion of the first limiting shell 51, springs fixedly connected with the inner cavity surface of the first limiting shell 51 are arranged on two sides of the outer surface of the two fixing hook plates 52, limiting frames 53 are arranged in the middle of the inner cavity of the first limiting shell 51, limiting handles 54 are extended to the outer portion of the first limiting shell 51, two connecting mechanisms 55 are arranged on two sides of the upper inner cavity of the first limiting shell 51, and four connecting mechanisms 55 are flush with one upper end of the first limiting shell 51.
Specifically, after the upper clamping device 7 is fixed at the upper end of the lower clamping device 5, the pushing device 4 pushes the limiting handle 54 in the inner cavity of the limiting frame 53 to move to a side close to the natural gas pipeline, and after a period of time, the surface of the limiting handle 54 contacts with the surface of the natural gas pipeline, so that the limiting handle 54 clamps and fixes the natural gas pipeline.
Further, in the process that the limiting handle 54 moves to one side close to the natural gas pipeline under the pushing of the pushing device 4, the moving distance of the limiting handle 54 can be controlled according to the diameter of the natural gas pipeline, so that the device can clamp and fix the natural gas pipelines with different diameters.
Further, the concave plate contacted with the natural gas pipeline by the limiting handle 54 is made of rubber, so that damage to the surface of the natural gas pipeline by the limiting handle 54 can be avoided in the process of clamping the natural gas pipeline by the limiting handle 54.
In order to guide the hydraulic oil in the pushing device 4 into the inner cavity of the limit frame 53 in the inner cavity of the upper clamping device 7, meanwhile, in order to avoid leakage of the hydraulic oil, as shown in fig. 4, the connecting mechanism 55 comprises a sealing tube 551, a connecting shell 552 is arranged at the lower end of the sealing tube 551, the inner cavity of the sealing tube 551 is communicated with the inner cavity of the connecting shell 552, a supporting plate 553 is arranged at the lower part of the inner cavity of the connecting shell 552, a second spring 554 is arranged at the upper end of the supporting plate 553, a sealing plate is arranged at the upper end of the second spring 554, a sealing ring 555 is arranged at the middle part of the upper end of the sealing plate, the sealing ring 555 is in sliding connection with the lower part of the inner cavity of the sealing tube 551, and a plurality of transfusion holes 556 are formed in the lower part of the sealing ring 555 in a penetrating mode.
The natural gas pipeline is clamped and fixed by utilizing the cooperation of the upper clamping device 7 and the lower clamping device 5, as shown in fig. 3 and 4, the upper clamping device 7 comprises a second limiting shell 71, both sides of the upper part of the inner cavity of the second limiting shell 71 are also provided with a limiting frame 53 and a limiting handle 54, the mounting directions of the limiting frame 53 and the limiting handle 54 in the inner cavity of the second limiting shell 71 and the mounting directions of the limiting frame 53 and the limiting handle 54 in the inner cavity of the first limiting shell 51 are opposite, both sides of the lower end of the second limiting shell 71 are respectively provided with two sealing elements 72, the four sealing elements 72 are respectively connected with the two limiting frames 53 on the upper part of the inner cavity of the second limiting shell 71 through hydraulic pipes, both middle parts of both sides of the lower end of the second limiting shell 71 are respectively provided with a second fixing hook plate 73, the second fixing hook plate 73 is matched with the fixing hole 511, and the second fixing hook plate 73 is matched with the first fixing hook plate 52.
Further, the sealing element 72 is matched with the sealing element 551, the size of the sealing element 72 is gradually decreased from top to bottom, the diameter of the inner cavity of the sealing element 551 is also gradually decreased from top to bottom, and hydraulic oil leakage can be avoided after the sealing element 551 contacts with the sealing element 72.
Specifically, in the process of fixing the upper clamping device 7 at the upper end of the lower clamping device 5, the second fixing hook plate 73 needs to be inserted into the inner cavity of the first limiting shell 51 through the fixing hole 511, the second limiting shell 71 is fixed at the upper end of the first limiting shell 51 through the cooperation between the second fixing hook plate 73 and the first fixing hook plate 52, in the process, four sealing elements 72 at the lower end of the second limiting shell 71 also need to be inserted into the inner cavity of the connecting mechanism 55, so that the connecting mechanism 55 guides hydraulic oil in the inner cavity of the pushing device 4 into the inner cavities of the two limiting frames 53 at the upper part of the inner cavity of the second limiting shell 71, and therefore, the two limiting handles 54 at the upper part of the inner cavity of the second limiting shell 71 can also clamp and fix the natural gas pipeline.
Further, when the fixed relation between the second limiting shell 71 and the first limiting shell 51 needs to be released, the pull plate 521 can be pulled to a side far away from the natural gas pipeline, so that the first fixing hook plate 52 is not contacted with the surface of the second fixing hook plate 73, and the limiting state of the first fixing hook plate 52 to the second fixing hook plate 73 is released, at this time, the second limiting shell 71 can be lifted upwards, so that the second fixing hook plate 73 is pulled out of the inner cavity of the first limiting shell 51, and then the first fixing hook plate 52 is pushed to return to the initial position by the spring between the first fixing hook plate 52 and the first limiting shell 51.
Further, during the process of inserting the sealing member 72 into the inner cavity of the connection mechanism 55, the lower end of the sealing member 72 will contact with the upper end of the sealing ring 555, and the sealing member 72 will push the sealing ring 555 to move downwards, so that the sealing ring 555 pushes the second spring 554 to compress through the sealing plate, during the downward movement of the sealing ring 555, the inner cavity of the transfusion hole 556 will gradually enlarge the communication area with the inner cavity of the connection housing 552, and after the surface of the sealing member 72 is completely contacted with the inner cavity surface of the sealing tube 551, at this time, the communication area between the transfusion hole 556 and the connection housing 552 is the largest.
In order to drive the lower clamping device 5 and the upper clamping device 7 to move, so that the lower clamping device 5 and the upper clamping device 7 clamp and fix the natural gas pipeline, as shown in fig. 5, the pushing device 4 comprises a hydraulic tank 41, a first piston 42 is arranged in the middle of the inner cavity of the hydraulic tank 41, a plurality of springs are arranged at the upper end of the first piston 42, a push rod 43 is arranged in the middle of the lower end of the first piston 42, the lower end of the push rod 43 extends to the outside of the hydraulic tank 41, the upper part of the inner cavity of the hydraulic tank 41 is communicated with the inner cavities of two limiting frames 53 in the inner cavity of a limiting shell 51 through two hydraulic pipes, and the upper part of the inner cavity of the hydraulic tank 41 is also communicated with the inner cavities of connecting shells 552 in four connecting mechanisms 55 through the hydraulic pipes respectively.
Specifically, after the upper clamping device 7 is fixed at the upper end of the lower clamping device 5, the first piston 42 is pushed to move upwards by the push rod 43, so that the first piston 42 pushes hydraulic oil in the inner cavity of the first hydraulic tank 41 to enter the inner cavity of the limiting frame 53 and the connecting mechanism 55 in the inner cavity of the first limiting shell 51 through corresponding hydraulic pipes, and the hydraulic oil entering the inner cavity of the limiting frame 53 pushes the limiting handle 54 to move, so that the limiting handle 54 clamps and fixes the natural gas pipeline.
Further, the hydraulic oil entering the inner cavity of the connecting mechanism 55 firstly enters the inner cavity of the connecting shell 552, then enters the inner cavity of the sealing ring 555 through the infusion hole 556, and then enters the inner cavity of the limiting frame 53 at the upper part of the inner cavity of the limiting shell II 71 through the sealing piece 72 and the hydraulic pipe, so that the corresponding limiting handle 54 is pushed to move.
Before the upper clamping device 7 and the lower clamping device 5 are detached, no force is applied to the push rod 43, so that the spring at the upper end of the first piston 42 pushes the first piston 42 to return to the initial position, hydraulic oil in the inner cavities of the four limiting frames 53 can be sucked into the inner cavity of the hydraulic box 41 again in the process, and the hydraulic oil is prevented from flowing out when the upper clamping device 7 and the lower clamping device 5 are detached.
Further, when the limiting handles 54 on the upper side and the lower side support and fix the natural gas pipeline, a force is given to the first limiting shell 51 and the second limiting shell 71 to separate from each other, the force acts between the first fixing hook plate 52 and the second fixing hook plate 73, the fixing strength of the first limiting shell 51 and the second limiting shell 71 is enhanced, and the action that the upper clamping device 7 is removed from the lower clamping device 5 before hydraulic oil is led into the inner cavity of the pushing device 4 by a worker can be avoided to a certain extent.

According to the embodiment, the supporting device 2 is further improved on the basis of the first embodiment, the supporting device 2 can drive the pushing device 4 to move, meanwhile, the supporting device 2 is utilized to support the lower clamping device 5 and the upper clamping device 7, and then the lower clamping device 5 and the upper clamping device 7 are used to support a natural gas pipeline, as shown in fig. 6 and 7, the supporting device 2 comprises two rotating cylinders 21, a plurality of limiting holes are formed in the upper portions of the two rotating cylinders 21, limiting mechanisms 22 are rotatably mounted at the ends of the two rotating cylinders 21, first screws 23 are connected with the middle portions of inner cavities of the two rotating cylinders 21 in a threaded mode, one ends of the first screws 23, which are far away from each other, extend to the outer portions of the two rotating cylinders 21 respectively, the threads on the outer surfaces of the first screws 23 are opposite in direction, the lower ends of the first screws 23 are fixedly connected with the upper ends of the base 1, a plurality of limiting grooves 231 are formed in the upper portions of the outer surfaces of the first screws 23, a plurality of positioning blocks 232 are formed in the upper portions of the outer surfaces of the first screws 23, limiting plates 25 are arranged in the upper portions of the first screws 23, the upper portions of the first screws 23 are provided with positioning plates 25, the first screws 24 are connected with the upper ends of the first screws 24, and the second screws 24 are connected with the upper positioning plates 24, and the second screws 24 are connected with the upper ends of the upper positioning plates 24.
Specifically, before the reinforcing device is assembled, the first screw 23 located at the upper part and the positioning mechanism 25 are in a separated state, after the upper clamping device 7 is fixed at the upper end of the lower clamping device 5, the first screw 23 located at the upper part can be inserted into the inner cavity of the positioning mechanism 25, at this time, the upper part of the second screw 24 is also inserted into the inner cavity of the push rod 43, so that the push rod 43 limits the second screw 24, then the limiting mechanism 22 is gripped, so that the limiting mechanism 22 can be independently rotated, when the limiting mechanism 22 is independently rotated, the second screw 24 can be driven to extend out of the inner cavity of the first screw 23 located at the upper part, in the process that the second screw 24 extends upwards, the second screw 24 lifts up the first piston 42 through the push rod 43, and then hydraulic oil in the inner cavity of the hydraulic tank 41 enters into the inner cavity of the corresponding limiting frame 53 through the corresponding hydraulic pipe.
Further, after the two screws 24 extend upward to a corresponding length through the limiting mechanism 22, so that the limiting handles 54 in the lower clamping device 5 and the upper clamping device 7 are used for clamping and fixing the natural gas pipeline, a worker can loosen the limiting mechanism 22 and then drive one rotary drum 21 to rotate, and the limiting mechanism 22 can limit the two rotary drums 21 at the moment because the worker loosens the limiting mechanism 22, so that the rotary drum 21 can drive the other rotary drum 21 to rotate through the limiting mechanism 22.
Further, when the two rotating cylinders 21 are driven to rotate, the first screw rods 23 in the inner cavities of the two rotating cylinders 21 extend, and the first screw rods 23 positioned at the upper part are fixed through the positioning mechanism 25, and the lower clamping device 5 and the upper clamping device 7 clamp and fix the natural gas pipeline at the moment, so that when the first screw rods 23 extend, only the base 1 is driven to rapidly move downwards until the lower end of the base 1 is contacted with the ground, so that the supporting device 2 supports the lower clamping device 5 and the upper clamping device 7, and further the lower clamping device 5 and the upper clamping device 7 support the natural gas pipeline.
Further, when the rotary drum 21 is rotated, the first screw 23 located at the lower portion is fixed to the upper end of the base 1, but the base 1 is not in contact with the ground at this time, and the first screw 23 located at the lower portion cannot be limited, so the first screw 23 located at the lower portion may rotate along with the rotation of the rotary drum 21, and at this time, a worker is required to manually limit the first screw 23 located at the lower portion.
Further, since the two rotating cylinders 21 rotate to drive the limiting mechanism 22 to rotate along with it, in order not to affect the action of the second screw 24 on the pushing device 4, the threads on the second screw 24 are required to be identical to the threads on the first screw 23 located at the upper part, and when the rotating cylinders 21 drive the first screw 23 located at the upper part to extend a certain length, the limiting mechanism 22 will correspondingly descend by a corresponding height.
In order to facilitate the disassembly of the positioning mechanism 25 and the first screw 23 positioned on the upper portion, so as to achieve the purpose of convenient storage, as shown in fig. 8 and 9, the positioning mechanism 25 comprises a positioning shell 251, the upper end of the positioning shell 251 is fixedly connected with the middle part of the lower end of the positioning plate 26, a connecting ring 252 is rotatably arranged in the middle of the positioning shell 251, a plurality of elastic telescopic rods 253 are arranged on the inner side surface of the connecting ring 252, the plurality of elastic telescopic rods 253 are used in a matched mode with a plurality of limiting grooves 231, a spring 254 is arranged on the outer side of the bottom wall of an inner cavity of the positioning shell 251, the outer side end face of the spring 254 is fixedly connected with the inner side surface of the connecting ring 252, a plurality of positioning holes 255 are formed in a penetrating mode in the lower end of the positioning shell 251, and the plurality of positioning holes 255 are used in a matched mode with the plurality of positioning blocks 232.
Specifically, when the first screw 23 located at the upper part is inserted into the inner cavity of the positioning shell 251, the outer surface of the first screw 23 is firstly contacted with the surface of the protruding rod of the elastic telescopic rod 253, but the end surface of the protruding rod of the elastic telescopic rod 253 is an inclined surface, so that the upward movement of the first screw 23 is not blocked, when the first screw 23 located at the upper part moves upwards for a certain distance, the elastic telescopic rod 253 enters the inner cavity of the limiting groove 231, and then the first screw 23 located at the upper part is limited by the elastic telescopic rod 253, meanwhile, in the process of moving the first screw 23 located at the upper part upwards, the surface of the positioning block 232 is contacted with the inner cavity surface of the positioning hole 255, and the first screw 23 located at the upper part is limited again.
Further, when the first screw 23 located at the upper part needs to be removed from the inner cavity of the positioning mechanism 25, the connecting ring 252 can be rotated, so that the connecting ring 252 drives the elastic telescopic rod 253 to rotate, and after rotating for a certain angle, the elastic telescopic rod 253 is not contacted with the inner cavity surface of the limiting groove 231, and at this time, the first screw 23 can be removed from the inner cavity of the positioning mechanism 25.
Further, since the upper end of the positioning shell 251 is fixed to the lower end of the positioning plate 26, and the upper end of the positioning plate 26 is fixed to the lower end of the pushing device 4, and meanwhile, the lower portion of the positioning shell 251 limits the first screw 23 located at the upper portion, but the first screw 23 also limits the lower portion of the positioning shell 251, when the connecting ring 252 rotates, the positioning shell 251 cannot rotate, and the spring 254 is forced to wind up to generate elasticity when the connecting ring 252 rotates, so that after the first screw 23 located at the upper portion is taken out from the inner cavity of the positioning mechanism 25, the spring 254 may drive the connecting ring 252 to rotate, and may also drive the lower portion of the positioning shell 251 to rotate, or both, but finally the positions between the plurality of positioning holes 255 and the elastic telescopic rod 253 are unchanged.
In order to drive the second screw 24 to rotate, and further drive the pushing device 4 to operate, simultaneously, in the process of rotating the rotary cylinder 21 to support the lower clamping device 5 and the upper clamping device 7, the limiting mechanism 22 can rotate along with the rotary cylinder 21, so that no relative motion exists between the second screw 24 and the first screw 23 positioned at the upper part, as shown in fig. 10, the limiting mechanism 22 comprises a threaded ring 221, the inner side surface of the threaded ring 221 is in threaded connection with the outer surface of the second screw 24, the outer sides of the upper side and the lower side of the threaded ring 221 are respectively in rotational connection with one ends, close to each other, of the two rotary cylinders 21, a plurality of pushing pieces 222 are arranged in the middle of the threaded ring 221, hydraulic telescopic rods 223 are respectively arranged at the outer sides of the upper end and the lower end of the threaded ring 221, the hydraulic telescopic rods 223 at the upper side and the lower side are respectively matched with limiting holes on the two rotary cylinders 21, and the inner cavities of the hydraulic telescopic rods 223 at the upper side and the lower side and the inner cavities of the pushing pieces 222 are respectively connected through hydraulic pipes.

Specifically, when the second screw 24 needs to be driven to move upwards, the limiting mechanism 22 is held to push the pushing blocks 2222 of the pushing members 222 inwards, so that the pushing blocks 2222 push the second piston 2225 inwards through the connecting rod, and then hydraulic oil in the inner cavities of the hydraulic telescopic rods 223 on the upper side and the lower side enters the space between the sealing disc 2224 and the second piston 2225, so that the hydraulic telescopic rods 223 on the upper side and the lower side are not contacted with the inner cavities of the limiting holes on the mutually adjacent ends of the two rotating cylinders 21, and at this time, the pushing members 222 can rotate independently.
Further, when the second screw 24 is extended for a certain length, the limiting mechanism 22 is released, and at this time, the third spring on the surface of the second piston 2225 can push the second piston 2225 to return to the initial position, so that the hydraulic telescopic rods 223 on the upper side and the lower side enter the limiting hole again, and at this time, the two rotary cylinders 21 can be linked through the limiting mechanism 22.
