Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gas pipelines, and in particular relates to a cover plate culvert type high-pressure gas pipeline protection device. Background Art
[0002] Gas pipelines are generally installed underground. With the development of cities, road reconstruction and expansion projects are increasing, which has a great impact on the gas pipelines under the roads. Especially when the gas pipelines pass through the cover culverts, the soil layer above the cover culverts is relatively thin and easily affected by ground vehicles. Therefore, the gas pipelines need to be fixed by protective structures during installation so that the protective structures can protect the gas pipelines.
[0003] For example, in the Chinese utility model with the announcement number CN215721232U, named a cover plate culvert type high-pressure gas pipeline protection structure, a connecting plate for supporting the coarse sand on the upper part of the gas pipeline and a support block for supporting the connecting plate are arranged on both sides of the gas pipeline and fixed on the side wall of the prefabricated culvert platform. The connecting plate is an arc-shaped structure, and the two ends of the connecting plate are respectively connected to the support blocks on both sides and the arc center falls on the gas pipeline. Although the pressure on the gas pipeline is reduced by the above structural design, when some heavy vehicles travel on the cover plate culvert, the gas pipeline will still be squeezed, and the gas pipeline is prone to damage after a long time, so a cover plate culvert type high-pressure gas pipeline protection device is now needed. Utility Model Content
[0004] The purpose of the utility model is to provide a cover plate culvert type high pressure gas pipeline protection device with simple structure and reasonable design in order to solve the above problems.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A cover plate culvert type high-pressure gas pipeline protection device comprises a gas pipeline, a semi-circular plate is arranged on the upper side of the gas pipeline, and a support mechanism is arranged on both sides of the semi-circular plate respectively, the support mechanism comprises a sliding rod vertically arranged on both sides of the semi-circular plate, a plurality of inclined rods are rotatably arranged on the lower end of the sliding rod, a support component that pushes the plurality of inclined rods to open at the same time is slidably arranged on the upper end of the sliding rod, and a pushing component that pushes the support component to slide up and down the sliding rod is arranged on both sides of the semi-circular plate.
[0007] As a further optimization solution of the utility model, the spreading assembly includes a slide plate slidably mounted on a slide rod, and a support rod rotatably connected to the inclined rod is equidistantly arranged on the slide plate.
[0008] As a further optimization solution of the utility model, a plurality of grooves are provided on the slide plate, and a rotating shaft rotatably connected to the support rod is provided inside the plurality of grooves.
[0009] As a further optimization solution of the utility model, the pushing assembly includes a driving sleeve fixedly arranged on both sides of the semicircular arc plate, and the lower end of the driving sleeve is slidably sleeved on the upper end of the sliding rod and abuts against the sliding plate.
[0010] As a further optimization solution of the utility model, convex plates are integrally provided on both sides of the semicircular arc plate, a mounting plate is integrally provided on the upper end of the driving sleeve, and the mounting plate and the convex plate are connected by a plurality of fixing bolts.
[0011] As a further optimization scheme of the utility model, a top plate is fixedly provided at the lower end of the sliding rod, one ends of several inclined rods are rotatably provided on the circumferential surface of the top plate, several inclined rods are sleeved with reinforcement blocks, a rubber sleeve is provided between the semi-circular plate and the gas pipeline, and a reinforcement plate is provided on the upper side of the semi-circular plate.
[0012] The beneficial effect of the utility model is that in the utility model, by pressing the semi-arc plate downward, the convex plate can be driven to be pressed down, and the first buffering is performed by the convex plate. When the convex plate continues to be pressed down, the mounting plate and the driving sleeve are driven to be pressed down, and the slide plate is pushed to slide on the slide rod by the lower end of the driving sleeve. The slide plate slides down and drives the support rod to push the inclined rod. Since a plurality of inclined rods are provided, and an "umbrella"-shaped structure is formed between the plurality of inclined rods and the slide rod, the contact area with the soil can be increased to increase the resistance, further buffer the pressure, and transmit the pressure to the soil, thereby preventing the pressure on the upper side of the semi-arc plate from squeezing the gas pipeline and causing damage to the gas pipeline. The pressure can be buffered in multiple ways to ensure that the gas pipeline can operate stably and for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Example 1
[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a cover plate culvert type high-pressure gas pipeline protection device is buried in the soil. The protection device includes a gas pipeline 1. A semi-circular plate 2 is arranged on the upper side of the gas pipeline 1. The semi-circular plate 2 is made of a rigid material, such as stone or stainless steel. A support mechanism is arranged on both sides of the semi-circular plate 2. The support mechanism includes a slide bar 10 vertically arranged on both sides of the semi-circular plate 2. A plurality of inclined rods 13 are rotatably arranged at the lower end of the slide bar 10. A slide plate 9 is slidably sleeved on the slide bar 10. A plurality of grooves are opened on the slide plate 9. The inner sides of the plurality of grooves are rotatably connected to a rotating shaft 14. The plurality of rotating shafts 14 are rotatably provided with support rods 15 rotatably connected to the inclined rods 13. Pushing components are provided on both sides of the arc plate 2 to push the support component to slide up and down on the slide bar 10. When in use, when a heavy vehicle travels above the cover culvert, it will squeeze the soil, and the pressure will be transmitted to the upper side of the semi-circular arc plate 2, so that the semi-circular arc plate 2 moves down on the upper side of the gas pipeline 1, driving the pushing component to move down, and the push slide plate 9 will slide up and down on the slide bar 10 through the pushing component, pushing multiple support rods 15 to drive the inclined rod 13 to open. Since the support rods 15 and the inclined rods 13 are buried in the soil, they will be subject to soil resistance during the opening process, thereby buffering the pressure and transmitting it to the soil to prevent the semi-circular arc plate 2 from descending too much and causing damage to the gas pipeline 1.
[0020] like Figure 2 As shown, a top plate 11 is fixedly provided at the lower end of the slide bar 10, one end of a plurality of inclined rods 13 is rotatably provided on the circumferential surface of the top plate 11, a plurality of inclined rods 13 are sleeved with reinforcing blocks 12, a rubber sleeve 4 is provided between the semicircular plate 2 and the gas pipeline 1, and the rubber sleeve 4 can prevent the semicircular plate 2 from scratching the gas pipeline 1 and can also play a buffering role, and a reinforcing plate 3 is provided on the upper side of the semicircular plate 2. When in use, the reinforcing block 12 can increase the contact area with the soil, further increase the resistance of the inclined rod 13, and improve the protective effect.
[0021] like Figure 1 , Figure 2As shown, the pushing assembly includes a driving sleeve 8 fixedly arranged on both sides of the semi-circular arc plate 2, the lower end of the driving sleeve 8 is slidably sleeved on the upper end of the slide bar 10 and abuts against the slide plate 9, convex plates 6 are integrally arranged on both sides of the semi-circular arc plate 2, and a mounting plate 7 is integrally arranged on the upper end of the driving sleeve 8, and the mounting plate 7 is connected to the convex plate 6 by a plurality of fixing bolts 5. When in use, the convex plate 6 and the mounting plate 7 are driven to descend by the semi-circular arc plate 2, and the mounting plate 7 pushes the lower end of the driving sleeve 8 to slide down, and the lower end of the driving sleeve 8 slides on the slide bar 10, thereby pushing the slide plate 9 to slide up and down the slide bar 10, and then the plurality of inclined rods 13 can be pushed to open by the support rod 15. Since the plurality of inclined rods 13 are buried in the soil, they will be subject to the resistance of the soil, so that the pressure can be transmitted to the soil, thereby buffering the pressure and preventing the pressure from damaging the gas pipeline 1.
[0022] It should be noted that, when using this cover culvert type high-pressure gas pipeline protection device, firstly, multiple reinforcement blocks 12 are sleeved on the inclined rods 13, and then the multiple inclined rods 13 are opened and buried in the soil. When buried, the sliding rod 10 is in a vertical state, and the mounting plate 7 at the upper end of the sliding rod 10 is fixed to the convex plates 6 on both sides of the semi-circular plate 2 by fixing bolts 5, and when the semi-circular plate 2 is sleeved on the upper side of the gas pipeline 1, a rubber sleeve 4 can be laid between the two.
[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
