Description

Technical Field

[0001] This utility model belongs to the field of gas pipelines, specifically a gas pipeline protection device. Background Technology

[0002] A gas pipeline protection device is used to ensure the safe operation of gas transmission pipelines and prevent damage caused by external impacts or the intrusion of excavation tools (such as bucket teeth) during construction. In practical applications, some gas pipelines are laid on the ground, cross roads, are located at the edge of construction sites, or are at valve well outlets. These sections of the gas pipeline are exposed or buried shallowly. For the specific scenario of mechanical protection of exposed gas pipeline sections, this solution addresses the issues of impact resistance, compression resistance, and prevention of accidental injury from third-party construction. Existing gas pipeline protection devices typically focus on only a single function; for example, crash barriers only prevent impacts, and warning signs only provide warnings. Crash barriers are bulky and simplistic, warning signs are easily overlooked, and there is a lack of effective compression resistance structures. Therefore, we have designed a gas pipeline protection device that provides impact resistance, compression resistance, prevention of accidental excavation, and intrusion warnings.

First angle steels are respectively installed on the left and right sides of the gas pipeline, and are fixedly mounted on the base plate by support rods. An arc-shaped steel plate is positioned above the two first angle steels. One side of the arc-shaped steel plate is hinged to one of the first angle steels, and the other side is detachably connected to the other first angle steel. First rotating shafts are rotatably mounted on both sides of the first angle steels. Warning signs are fixedly mounted on the outer circumference of each first rotating shaft. Coaxial bevel gears are fixedly mounted on the outer ends of the first rotating shafts. Bevel gear rings are meshed on one side of each bevel gear. Coaxial second rotating shafts are fixedly mounted on the inner circumference of each bevel gear ring. The second rotating shafts are rotatably mounted on the first angle steels via bearing seats. Several levers are fixedly mounted on the outer circumference of each second rotating shaft.

[0006] As described above, a gas pipeline protection device is provided between the arc-shaped steel plate and the gas pipeline.

The two sides of the triangular support plate abut against the two support blocks in sequence, and the top of the triangular support plate abuts against the top of the inner circumference of the arc-shaped steel plate.

[0007] As described above, in a gas pipeline protection device, horizontal stop bars are fixedly installed on the outer wall of the first angle steel, and stop blocks are fixedly installed on the inner side of the warning sign. When the stop block rotates to a certain angle along the axis of the first rotating shaft, the stop bar can prevent the corresponding stop block from continuing to rotate.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] A gas pipeline protection device, such as Figure 1 , 2As shown in Figure 3, the system includes a base plate 1 on which a gas pipeline 100 is mounted. Two first angle steels 2 are symmetrically distributed on the left and right sides of the gas pipeline 100, with the distance between the openings on their upper sides greater than the outer diameter of the gas pipeline 100. The first angle steels 2 are fixedly mounted on the base plate 1 via support rods 3. An arc-shaped steel plate 4 is positioned above the two first angle steels 2, with one side of the arc-shaped steel plate 4 hinged to one of the first angle steels 2 and the other side detachably connected to the other first angle steel 2. First rotating shafts 5 are rotatably mounted on both sides of each first angle steel 2. Support platforms 6 are fixedly mounted on the left and right sides of each first angle steel 2, with bearings fixedly connected to the outer sides of the support platforms 6. The outer ring of the bearing and the inner ring of the bearing are respectively fixedly connected to the outer circumference of the inner end of the first rotating shaft 5. Warning signs 7 are respectively fixedly installed on the outer circumference of the first rotating shaft 5. The warning signs 7 are located below the first rotating shaft 5. Coaxial bevel gears 8 are respectively fixedly installed on the outer end of the first rotating shaft 5. Bevel gear rings 9 are respectively meshed on one side of the bevel gear 8. Coaxial second rotating shafts 10 are respectively fixedly installed on the inner circumference of the bevel gear rings 9. The axes of the first rotating shaft 5 and the second rotating shaft 10 are perpendicular to each other. The second rotating shaft 10 is respectively rotatably installed on the first angle steel 2 through the bearing seat. The outer circumference of the second rotating shaft 10 is respectively rotatably connected to the inner circumference of the bearing seat. The outer circumference of the bearing seat is respectively fixedly connected to the outer wall of the first angle steel 2. Several levers 11 are respectively fixedly installed on the outer circumference of the second rotating shaft 10. This utility model has a simple structure and ingenious design. The synergistic function of the first angle steel 2 and the arc-shaped steel plate 4 in preventing impact and squeezing, combined with the intrusion warning of the warning sign 7, solves the problem that existing gas pipeline protection devices usually only focus on a single function. The flipping of the warning sign 7 can bring an immediate and strong visual warning when intrusion occurs, which is better than the warning effect of a single warning sign. Moreover, the purely mechanical characteristics improve the reliability of the protection device and its practicality with low maintenance costs.When using this utility model, detach one end of the arc-shaped steel plate 4 from the first angle steel 2, rotate the arc-shaped steel plate 4 along the hinge axis between the arc-shaped steel plate 4 and the first angle steel 2 until the upper opening between the two first angle steels 2 is fully exposed, insert the gas pipe 100 between the two first angle steels 2 through the upper opening between the two first angle steels 2, so that the outer periphery of the gas pipe 100 abuts against the lower side of the inner wall of the first angle steel 2, then rotate the arc-shaped steel plate 4 to close it, and detachably connect the arc-shaped steel plate 4 to the first angle steel 2, and fix the base plate 1 on the ground; the two first angle steels 2 and the arc-shaped steel plate 4 hold the gas pipe 100 The enclosure protects the gas pipeline 100 from direct impact. When subjected to vertical or oblique impacts such as vehicle collisions or falling heavy objects, the arc-shaped steel plate 4 undergoes elastic deformation and bends downward to absorb impact energy, preventing the impact from directly acting on the gas pipeline 100. After the impact, the arc-shaped steel plate 4 returns to its original shape due to its own material elasticity. When a vehicle hits either side, the lever 11 rotates, driving the second rotating shaft 10 and the bevel gear ring 9 to rotate. The bevel gear ring 9 drives the first rotating shaft 5 and the warning sign 7 to rotate through the bevel gear 8, causing the warning sign 7 to flip from below to above, thereby providing an immediate, strong, and passive visual warning, alerting the driver to brake immediately.

[0018] Specifically, as shown in the figure, a triangular support plate 20 is provided between the arc-shaped steel plate 4 and the gas pipeline 100 in this embodiment. The triangular support plate 20 is located inside the two first angle steels 2. Support blocks 21 are fixedly installed on the inner walls of the first angle steels 2 respectively. The two sides of the triangular support plate 20 abut against the two support blocks 21 in sequence, and the top of the triangular support plate 20 abuts against the top of the inner circumference of the arc-shaped steel plate 4. The triangular support plate 20 can play a role in distributing the load, effectively dispersing the vertical pressure transmitted from the arc-shaped steel plate 4 to the first angle steels 2 on both sides and the foundation through the triangular inclined structure, significantly reducing the point pressure borne by the gas pipeline 100.

[0019] Specifically, as shown in the figure, in this embodiment, horizontal stop bars 30 are fixedly installed on the outer wall of the first angle steel 2. The stop bars 30 are located directly above the corresponding first rotating shaft 5. Stop blocks 31 are fixedly installed on the inner side of the warning sign 7. When the stop blocks 31 rotate along the axis of the first rotating shaft 5 to a certain angle, the stop bars 30 can prevent the corresponding stop blocks 31 from continuing to rotate. When the first rotating shaft 5 rotates and drives the warning sign 7 to rotate, the warning sign 7 drives the stop blocks 31 to rotate along the first rotating shaft 5. When the warning sign 7 and the stop blocks 31 rotate to the top of the first rotating shaft 5, the stop bars 30 can abut against the corresponding stop blocks 31 and cooperate. The stop blocks 31 prevent the corresponding stop bars 30 and the warning sign 7 from continuing to rotate, thereby keeping the warning sign 7 at the top and playing a warning role.

[0020] Furthermore, as shown in the figure, the bevel ring 9 described in this embodiment is connected to the corresponding second rotating shaft 10 via a torsion spring. One end of the torsion spring is fixedly connected to one side of the corresponding bevel ring 9, and the other end of the torsion spring is fixedly connected to the outer periphery of the corresponding second rotating shaft 10. When the lever 11 is struck, the lever 11 rotates, causing the second rotating shaft 10 to rotate. The second rotating shaft 10, through the torsion spring, causes the bevel ring 9 to rotate. The bevel ring 9 causes the bevel gear 8, the first rotating shaft 5, the warning sign 7, and the stop block 31 to rotate along the axis of the first rotating shaft 5. When the stop block 31 abuts against the corresponding stop lever 30, if the lever 11 continues to rotate, the lever 11 causes the second rotating shaft 10 to rotate. Since the blocking force of the stop lever 30 on the stop block 31 is greater than the force of the torsion spring causing the bevel ring 9 to rotate, the torsion spring cannot cause the bevel ring 9 to rotate. The torsion spring stores energy to prevent interference between the stop lever 30 and the stop block 31 from causing damage to both.

[0021] Furthermore, as shown in the figure, in this embodiment, a through hole 50 is opened at one end of the arc-shaped steel plate 4 and the first angle steel 2 that are detachably connected. The insertion rod 51 is slidably installed in the through hole 50. The insertion rod 51 is connected to the arc-shaped steel plate 4 through a spring 52. The spring 52 is fitted on the outer periphery of the insertion rod 51. One end of the spring 52 is fixedly connected to the outer periphery of the insertion rod 51, and the other end of the spring 52 is fixedly connected to the outer periphery of the arc-shaped steel plate 4. A slot 53 is opened on the first angle steel 2 corresponding to the insertion rod 51. Under the elastic force of the spring 52, the insertion rod 51 and the slot 53 are inserted and engaged. Pulling the insertion rod 51 outward causes the spring 52 to extend, allowing the insertion rod 51 to move out of the slot 53. At this time, the arc-shaped steel plate 4 can rotate along the hinge axis between the arc-shaped steel plate 4 and the first angle steel 2. When the through hole 50 is coaxial with the slot 53, the insertion rod 51 is inserted into the slot 53, and under the elastic force of the spring 52, the insertion rod 51 remains inserted in the slot 53, limiting the arc-shaped steel plate 4 and preventing the arc-shaped steel plate 4 from rotating.

[0022] Furthermore, as shown in the figure, a pull block 60 is fixedly installed on the outer end of the insertion rod 51 in this embodiment. Pulling the insertion rod 51 through the pull block 60 is more convenient and less strenuous.

[0023] Furthermore, as shown in the figure, the base plate 1 in this embodiment has several mounting holes 70. The mounting holes 70 facilitate the fixing of the base plate 1 to the ground.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
