Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline support technology, specifically a support and adjustment device for a natural gas pipeline bend. Background Technology

[0002] With the continuous growth of energy demand, natural gas, as a clean and efficient energy source, has an increasingly large pipeline transportation network. During the laying of natural gas pipelines, the support at bends is one of the key factors to ensure the safe operation of the pipelines.

[0003] Once the orientation of a traditional support device is determined during installation, it is difficult to make fine adjustments if a deviation is found. Often, the entire support structure needs to be disassembled and re-drilled for installation. This process is not only time-consuming and labor-intensive, but may also cause secondary damage to the pipeline, affecting its integrity and sealing.

[0004] Therefore, a support and adjustment device for bends in natural gas pipelines is provided to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a support and adjustment device for bends in natural gas pipelines to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a support and adjustment device for a natural gas pipeline bend, comprising a base, a lifting mechanism fixedly mounted on the upper surface of the base, a fixing ring mounted on the upper surface of the lifting mechanism, a plurality of positioning holes formed on the upper surface of the fixing ring, a bearing mounted on the upper surface of the lifting mechanism, an mounting plate above the bearing, a rotating shaft fixedly mounted on the lower surface of the mounting plate, the rotating shaft being disposed inside the bearing, a limit mechanism fixedly mounted on the lower surface of the mounting plate, and a support mechanism mounted on the upper surface of the mounting plate.

[0008] Furthermore, the lifting mechanism includes a screw, a threaded sleeve, and an adjusting handle. The screw is fixedly installed on the upper surface of the base, and the threaded sleeve is threadedly connected to the outer surface of the screw. Two sets of adjusting handles are fixedly installed on the outer surface of the threaded sleeve.

[0009] Furthermore, the limiting mechanism includes a mounting housing, a spring, and a through groove. The mounting housing is fixedly mounted on the lower surface of the mounting plate, the spring is installed inside the mounting housing, and a through groove is provided on one side of the mounting housing.

[0010] Furthermore, the limiting mechanism also includes a movable plate, a limiting rod, and a pull rod. One end of the spring is fixedly mounted with the movable plate, and the lower surface of the movable plate is fixedly mounted with the limiting rod. The limiting rod extends to the outer surface of the mounting housing and is inserted into the positioning hole. The outer surface of the movable plate is fixedly mounted with the pull rod, and the pull rod extends through a through groove to the outer surface of the mounting housing and is slidably connected to the inner wall of the through groove.

[0011] Furthermore, the support mechanism includes a lower support block, an upper support block, and a buffer pad. The lower support block is fixedly installed on the upper surface of the mounting plate, and the upper support block is installed on the upper surface of the lower support block.

[0012] Furthermore, buffer pads are installed on the inner surfaces of both the lower support block and the upper support block.

[0013] This utility model has the following beneficial effects:

[0014] (1) By pulling the pull rod, the pull rod drives the movable plate to slide upward and squeeze the spring, so that the spring gradually contracts. When the limiting rod is disengaged from the positioning hole, the mounting plate can rotate around the bearing. The rotation of the mounting plate can drive the support mechanism to adjust the angle. After adjusting to the appropriate angle, the pull rod is released, the spring recovers its elasticity and pushes the limiting rod into the corresponding positioning hole to achieve re-limiting. This achieves the effect of fine adjustment of the direction of the support mechanism, avoiding the situation where the direction of the support mechanism is incorrectly installed and the whole structure needs to be disassembled and re-drilled for installation.

[0015] (2) By rotating the adjustment handle, the threaded sleeve is threadedly connected to the outer surface of the screw. Rotating the adjustment handle causes the threaded sleeve to rotate and rise or fall on the screw. The rise or fall of the threaded sleeve will cause the fixed ring, bearing and mounting plate connected to its upper surface to rise or fall together, thereby realizing the vertical height adjustment of the entire support mechanism to adapt to the support of natural gas pipeline bends with different height requirements.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1 - Figure 4 As shown, this utility model is a support and adjustment device for a natural gas pipeline bend, including a base 1, a lifting mechanism fixedly installed on the upper surface of the base 1, a fixing ring 5 installed on the upper surface of the lifting mechanism, a plurality of positioning holes 501 opened on the upper surface of the fixing ring 5, a bearing 6 installed on the upper surface of the lifting mechanism, an mounting plate 7 provided above the bearing 6, a rotating shaft 701 fixedly installed on the lower surface of the mounting plate 7, the rotating shaft 701 is located inside the bearing 6, a limit mechanism 8 fixedly installed on the lower surface of the mounting plate 7, and a support mechanism installed on the upper surface of the mounting plate 7.

[0026] The lifting mechanism includes a screw 2, a threaded sleeve 3 and an adjusting handle 4. The screw 2 is fixedly installed on the upper surface of the base 1. The threaded sleeve 3 is threadedly connected to the outer surface of the screw 2. Two sets of adjusting handles 4 are fixedly installed on the outer surface of the threaded sleeve 3.

[0027] When the height of the support device needs to be adjusted, the user can rotate the adjustment handle 4. Since the threaded sleeve 3 is threadedly connected to the outer surface of the screw 2, rotating the adjustment handle 4 will cause the threaded sleeve 3 to rotate and rise or fall on the screw 2. When the threaded sleeve 3 rises or falls, it will drive the fixed ring 5, bearing 6 and mounting plate 7 connected to its upper surface to rise or fall together, thereby realizing the vertical height adjustment of the entire support mechanism to adapt to the support of natural gas pipeline bends with different height requirements.

[0028] The limiting mechanism 8 includes a mounting housing 801, a spring 802, and a through groove 803. The mounting housing 801 is fixedly mounted on the lower surface of the mounting plate 7. The spring 802 is installed inside the mounting housing 801. A through groove 803 is provided on one side of the mounting housing 801.

[0029] The limiting mechanism 8 also includes a movable plate 804, a limiting rod 805, and a pull rod 806. One end of the spring 802 is fixedly mounted on the movable plate 804. The lower surface of the movable plate 804 is fixedly mounted on the limiting rod 805. The limiting rod 805 extends to the outer surface of the mounting housing 801 and is inserted into the positioning hole 501. The outer surface of the movable plate 804 is fixedly mounted on the pull rod 806. The pull rod 806 extends through the through groove 803 to the outer surface of the mounting housing 801 and is slidably connected to the inner wall of the through groove 803.

[0030] When the direction of the support mechanism needs to be fine-tuned, the user can pull the lever 806. The lever 806 drives the movable plate 804 to slide upward and compress the spring 802, causing the spring 802 to gradually contract. When the limit rod 805 disengages from the positioning hole 501, the mounting plate 7 can rotate around the bearing 6. The rotation of the mounting plate 7 can drive the support mechanism to adjust its angle. After adjusting to the appropriate angle, the lever 806 is released, the spring 802 regains its elasticity and pushes the limit rod 805 into the corresponding positioning hole 501, achieving re-limiting and achieving the effect of fine-tuning the direction of the support mechanism. This avoids the situation where the direction of the support mechanism is incorrectly installed and the whole structure needs to be disassembled and re-drilled for installation.

[0031] The support mechanism includes a lower support block 9, an upper support block 10, and a buffer pad 11. The lower support block 9 is fixedly installed on the upper surface of the mounting plate 7, and the upper support block 10 is installed on the upper surface of the lower support block 9.

[0032] Both the lower support block 9 and the upper support block 10 have buffer pads 11 installed on their inner surfaces.

[0033] In use, the lower support block 9 and the upper support block 10 are connected by bolts so that the lower support block 9 and the upper support block 10 together support the bend of the natural gas pipeline. The buffer pads 11 installed on their inner surfaces can play a buffering role, reducing the impact of vibration generated by the natural gas pipeline during operation on the support device, and at the same time preventing the support blocks from damaging the pipeline surface, thus protecting the integrity of the natural gas pipeline.

[0034] When the height of the support device needs to be adjusted, the user can rotate the adjustment handle 4. Since the threaded sleeve 3 is threadedly connected to the outer surface of the screw 2, rotating the adjustment handle 4 will cause the threaded sleeve 3 to rotate and rise or fall on the screw 2. When the threaded sleeve 3 rises or falls, it will drive the fixed ring 5, bearing 6 and mounting plate 7 connected to its upper surface to rise or fall together, thereby realizing the vertical height adjustment of the entire support mechanism to adapt to the support of natural gas pipeline bends with different height requirements.

[0035] When a fine adjustment of the direction of the support mechanism is required, the user can pull the lever 806. The lever 806 drives the movable plate 804 to slide upward and compress the spring 802, causing the spring 802 to gradually contract. When the limiting rod 805 disengages from the positioning hole 501, the mounting plate 7 can rotate around the bearing 6. The rotation of the mounting plate 7 can drive the support mechanism to adjust its angle. After adjusting to the appropriate angle, the lever 806 is released, the spring 802 regains its elasticity and pushes the limiting rod 805 into the corresponding positioning hole 501, achieving re-limiting and achieving the effect of fine adjustment of the direction of the support mechanism. This avoids the situation where the direction of the support mechanism is incorrectly installed and the whole thing needs to be disassembled and re-drilled for installation.
