[0002] Currently, natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced from oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial users; they are also known as gas transmission pipelines.
[0003] In the prior art, utility model patent with announcement number CN214331682U provides a docking device for natural gas pipeline installation, including a base plate. A sliding groove is formed in the middle of the upper side wall of the base plate. Slider blocks are movably connected to both ends of the sliding groove. A fixing mechanism is fixedly installed on the upper end of both sets of sliders. The fixing mechanism includes a first card seat and a second card seat. The right ends of the first card seat and the second card seat are movably installed by hinges. A circular groove is formed in the middle of the first card seat and they correspond to each other. A clamping block is provided on the inner side wall of the first card seat. A first bearing is fixedly installed in the middle of the upper end of the clamping block. A first screw hole is formed in the middle of the upper end of the first card seat. The first screw hole is connected to the circular groove. A first screw is screwed into the first screw hole. The lower end of the first screw is fixedly connected to the central shaft of the first bearing.
[0004] The current natural gas pipeline installation docking device requires rotating the first screw to fix the natural gas pipeline, which affects work efficiency. It also requires rotating two sets of second screws simultaneously to drive the rotation of both sets of screws, making it inconvenient to quickly connect the natural gas pipeline. Therefore, we propose a natural gas pipeline installation docking device to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 A docking device for installing a natural gas pipeline includes a workbench 1, a slider 2 slidably engaged on the workbench 1, a limiting seat 3 fixedly connected to the slider 2, and a limiting mechanism 4 provided on the limiting seat 3. The limiting mechanism 4 is used to limit the natural gas pipeline within the limiting seat 3. The limiting mechanism 4 includes a strap 41 with one end connected to the inner wall of the limiting seat 3. The free end of the strap 41 moves through the top of the limiting seat 3 and is connected to a winding wheel 42. The winding wheel 42 is rotatably mounted on a bracket 43 and is used to wind up and unwind the strap 41. The strap 41 is symmetrically distributed on both sides of the center of the top of the limiting seat 3 at the connection point and the point where the strap 41 passes through the limiting seat 3. The length of the strap 41 is greater than the outer diameter of the natural gas pipeline. The drive motor of the winding wheel 42 is mounted on the bracket 43, and a motor with a brake can be selected. The bottom of the bracket 43 is located on the top of the limiting seat 3. The limiting seat 3 is a tubular structure (two sets of limiting mechanisms 4 can be set on one set of limiting seats 3). The inner diameter of the limiting seat 3 is greater than the inner diameter of the natural gas pipeline.
[0022] Insert the natural gas pipeline into the space between the top of the limiting seat 3 and the binding strap 41, then drive the winding wheel 42 to wind up the binding strap 41. The binding strap 41 tightens and fixes the natural gas pipeline on the limiting seat 3, making it easy to fix natural gas pipelines of various diameters and improving work efficiency.
[0023] The worktable 1 is equipped with an adjustment mechanism 5, which is used to drive the movement of two sets of sliders 2. The adjustment mechanism 5 includes an operating rod 51 that rotates through the side wall of the worktable 1. One end of the operating rod 51 is connected to a gear 1 52 and is used to drive the rotation of the gear 1 52. The gear 1 52 meshes with a gear 2 53. The gear 2 53 is located on a connecting shaft 54. Both ends of the connecting shaft 54 are connected to screws 55 for threaded transmission of the slider 2. The operating rod 51 is rotatably engaged on the worktable 1. A handle can be provided at the outer end of the operating rod 51. Alternatively, a servo motor can be provided on the outer wall of the worktable 1 to connect the operating rod 51. Both gear 1 52 and gear 2 53 rotate on the worktable 1. Both gear 1 52 and gear 2 53 are bevel gears. The connecting shaft 54 is rotatably engaged on the worktable 1. One end of the shaft 54 is fixedly connected to the gear 2 53. The two sets of threads of the screw 55 have opposite directions of rotation. The end of the screw 55 away from the connecting shaft 54 is threaded through the slider 2.
[0024] Rotating the operating lever 51 causes the first gear 52 to rotate. The first gear 52 meshes with the second gear 53, causing the connecting shaft 54 to rotate on the worktable 1. The connecting shaft 54 drives two sets of screws 55 to rotate, and the two sets of screws 55 drive two sets of sliders 2 to move towards each other. The sliders 2 drive the limit seat 3 and the natural gas pipeline to move accordingly, thereby connecting the two sets of natural gas pipelines. This allows the two sets of sliders to move towards or away from each other via the operating lever 51, enabling the natural gas pipelines to be connected quickly.
[0025] Working principle: This utility model inserts a natural gas pipeline into the limiting seat 3 between the top and the binding strap 41. Then, the winding wheel 42 is driven to wind up the binding strap 41, which tightens the natural gas pipeline and fixes it on the limiting seat 3. This makes it easy to fix natural gas pipelines of various diameters, improving work efficiency. Rotating the operating lever 51 drives the first gear 52 to rotate. The first gear 52 meshes with the second gear 53, which drives the connecting shaft 54 to rotate on the worktable 1. The connecting shaft 54 drives two sets of screws 55 to rotate. The two sets of screws 55 drive two sets of sliders 2 to move towards each other. The sliders 2 drive the limiting seat 3 and the natural gas pipeline to move accordingly, thereby connecting the two sets of natural gas pipelines. This allows the two sets of sliders to move towards or away from each other through the operation lever 51, enabling the natural gas pipelines to be quickly connected.
[0026] The winding reel and motor are existing technologies and will not be described in detail here.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
