Description

Technical Field

[0001] The utility model belongs to the field of natural gas exploitation, in particular to a pipeline installation structure for long-distance natural gas exploitation. Background Art

[0002] Natural gas long-distance pipelines refer to pipeline systems used to transport natural gas between production sites, storage facilities, and user units. These pipelines usually span long distances and pass through different terrains and environmental conditions.

[0003] The existing Chinese patent CN213452061U discloses a pipeline installation structure for long-distance natural gas development, including a load-bearing fixed seat, the upper surface of which is connected with a high-strength fastening bolt, a connecting sliding rod is arranged at the center position of the upper surface of the load-bearing fixed seat, and an electric control device is installed at the middle position of one side of the load-bearing fixed seat; the upper end of the connecting sliding rod is connected to a limited support rod. The long-distance natural gas development pipeline installation structure can automatically and accurately adjust the height of the limited support rod, which is simple and convenient to operate, safe and reliable to adjust, thereby facilitating the installation of the long-distance natural gas development pipeline and avoiding the situation that the distance of the installed pipeline cannot be adjusted. When the length cannot be adapted during the installation of the pipeline, the height of the previous pipeline installation equipment can be raised or lowered to appropriately perform simple adjustments, thereby improving the applicability and use effect of the equipment.

[0004] However, the above-mentioned pipeline installation equipment cannot move the pipeline on the ground into the pipeline trench. During the installation process, the workers also need to cooperate with the lifting equipment for installation. Most of the existing lifting equipment uses ropes to lift the two ends of the pipeline. During the lifting process, the pipeline is prone to shaking, which greatly affects the construction efficiency of the workers. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a pipeline installation structure for long-distance natural gas development to solve the problem that when the pipeline is hoisted in the prior art, ropes are used to lift both ends of the pipeline, causing the pipeline to shake easily.

[0006] A pipeline installation structure for long-distance natural gas development includes: a lifting mechanism, including a lifting frame assembly, a positioning rod assembly slidably embedded in the outer side of the lifting frame assembly, a nut assembly rotatably embedded in the lifting frame assembly; and a limiting mechanism rotatably installed on the lifting frame assembly.

[0007] Preferably, the lifting frame assembly includes an externally threaded frame, a lifting ring is fixedly connected to the upper side of the externally threaded frame, a supporting inner ring is fixedly connected to the middle position of the lower side of the externally threaded frame, a group of fixing plates are also fixedly connected to the lower side of the externally threaded frame, and a limiting rod is also fixedly connected to the upper side of the externally threaded frame.

[0008] Preferably, the positioning rod assembly includes a connecting rod and a spring, one end of the connecting rod is fixedly connected to a bevel block, and the other end of the connecting rod is fixedly connected to a rubber block; the nut assembly includes a hollow nut, and the lower edge of the hollow nut is fixedly connected to an outer ring.

[0009] Preferably, the connecting rod is limitedly slidably embedded in the fixing plate, and the spring drives the inclined block away from the fixing plate; the hollow nut is rotatably embedded in the outer side of the external thread frame.

[0010] Preferably, the limiting mechanism comprises a limiting plate, a shaft ring is fixedly connected to the lower end of one side of the limiting plate, and a short rod is fixedly connected to the upper end of one side of the limiting plate.

[0011] Preferably, the shaft ring is rotationally limited and embedded on the limiting rod, and the limiting plate can limit the hollow nut.

[0012] Compared with the prior art, the utility model has the following beneficial effects: by inserting the hanging frame assembly into one end of the pipe, the positioning rod assembly can be moved by rotating the nut assembly, thereby easily fixing the pipe on the hanging frame assembly, so that the pipe can be stably lifted, greatly improving the installation efficiency of the staff; the limiting mechanism can effectively prevent the nut assembly and the hanging frame assembly from detaching, thereby preventing the nut assembly from falling off.

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a pipeline installation structure for long-distance natural gas development, comprising: a hoisting mechanism 1, including a hoisting frame assembly 11, a positioning rod assembly 12 slidably embedded in the outer side of the hoisting frame assembly 11, a nut assembly 13 rotatably embedded in the hoisting frame assembly 11; a limiting mechanism 2 rotatably installed on the hoisting frame assembly 11;

[0022] During installation, the hanging frame assembly 11 is inserted into one end of the pipe 3, and the nut assembly 13 is rotated to move the positioning rod assembly 12. The movement of the positioning rod assembly 12 will abut against the pipe 3, thereby fixing the pipe 3 on the hanging frame assembly 11. At this time, the pipe 3 can be moved to a suitable position by moving the hanging frame assembly 11, and the nut assembly 13 can be limited by the limiting mechanism 2, thereby preventing the nut assembly 13 and the hanging frame assembly 11 from detaching.

[0023] Specifically, the lifting frame assembly 11 includes an external threaded frame 111, a lifting ring 112 is fixedly connected to the upper side of the external threaded frame 111, a supporting inner ring 113 is fixedly connected to the middle position of the lower side of the external threaded frame 111, a group of fixing plates 114 are also fixedly connected to the lower side of the external threaded frame 111, and a limiting rod 115 is also fixedly connected to the upper side of the external threaded frame 111.

[0024] Specifically, the positioning rod assembly 12 includes a connecting rod 121 and a spring 122, one end of the connecting rod 121 is fixedly connected to a bevel block 123, and the other end of the connecting rod 121 is fixedly connected to a rubber block 124; the nut assembly 13 includes a hollow nut 131, and the lower edge of the hollow nut 131 is fixedly connected to an outer ring 132.

[0025] Specifically, the connecting rod 121 is limitedly slidably embedded on the fixing plate 114 , and the spring 122 drives the inclined block 123 away from the fixing plate 114 ; the hollow nut 131 is rotatably embedded on the outer side of the external thread frame 111 .

[0026] As can be seen from the above, rotating the hollow nut 131 causes the outer ring 132 to move downward, and the downward movement of the outer ring 132 will push the inclined block 123, and the movement of the inclined block 123 will cause the connecting rod 121 to drive the rubber block 124 to move, and the movement of the rubber block 124 will be close to the outside of the pipe 3, and the friction between the rubber block 124 and the pipe 3 can prevent the pipe 3 from falling off during the transfer process. The movement of the inclined block 123 will also compress the spring 122, and rotating the hollow nut 131 causes the outer ring 132 to move upward. When the outer ring 132 moves upward, the inclined block 123 will no longer be pushed. At this time, the resetting of the spring 122 will cause the inclined block 123 to drive the connecting rod 121 and the rubber block 124 to move, and the movement of the rubber block 124 will separate from the pipe 3, thereby facilitating the staff to remove the pipe 3, and the pipe 3 can be guided and positioned by supporting the inner ring 113.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the limiting mechanism 2 includes a limiting plate 21, a shaft ring 22 is fixedly connected to the lower end of one side of the limiting plate 21, and a short rod 23 is fixedly connected to the upper end of one side of the limiting plate 21.

[0028] Specifically, the shaft ring 22 is locked on the limiting rod 115 for limited rotation, and the limiting plate 21 can limit the hollow nut 131 .

[0029] As can be seen from the above, the collar 22 is moved on the limiting rod 115 through the short rod 23. When the limiting plate 21 moves onto the hollow nut 131, the hollow nut 131 can be limited to prevent the hollow nut 131 from falling. When the limiting plate 21 is detached from the hollow nut 131, the staff can remove the hollow nut 131.
