Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology, and in particular to a temporary pipeline protection device. Background Technology

[0002] Temporary pipelines refer to pipes or cables temporarily laid at construction sites for water supply, power supply, gas supply, etc. Various temporary pipelines often need to cross construction site roads. Due to the frequent changes in the work area at construction sites, temporary pipelines need to be moved frequently. If the pipelines are frequently exposed, it poses a safety hazard.

[0003] Existing temporary pipeline protection methods primarily involve cutting grooves in cement concrete pavements or digging trenches in earthen roads, directly burying the temporary pipelines, and then backfilling with medium-coarse sand. This method makes temporary pipelines susceptible to damage from passing vehicles, posing certain safety hazards. Furthermore, rerouting or dismantling temporary pipelines later is difficult, and reuse is also challenging. Some methods involve covering the pipelines with protective plates, such as arched covers. While simple to implement, lightweight protective plates offer limited protection, while high-strength plates require thicker plates, hindering construction. Moreover, these protective plates are typically fixed structures and cannot be adjusted to suit the protection needs of pipelines of varying sizes, resulting in poor adaptability to changing operating conditions and difficulties in storage and transportation. Summary of the Invention

[0004] In view of this, the present application provides a temporary pipeline protection device, which is composed of multiple plates connected by rotation. By using tension ropes, the device can be easily deformed to adapt to different heights. It is not only suitable for temporary protection of pipelines at different heights, but also has the characteristics of easy disassembly and storage.

[0005] The technical solution adopted in this invention is to design a temporary pipeline protection device, including a cover plate located above the pipeline. The two opposite ends of the cover plate are rotatably connected to a first side plate and a second side plate. A guide wheel located above the pipeline is provided on the cover plate. A tension rope is connected between the first side plate and the second side plate and passes over the guide wheel.

[0006] In some embodiments, the tension rope is locked and fixed to the first side plate and / or the second side plate by a locking mechanism.

[0007] In some embodiments, a plug rod that can be inserted into the ground is fixed below the cover plate on both sides of the pipeline, and a sliding sleeve is slidably fitted on the plug rod, with the guide wheel disposed on the sliding sleeve.

[0008] In some embodiments, the lower end of the sliding sleeve is provided with a support portion that supports the ground.

[0009] In some embodiments, the support portion is at a greater height from the guide wheel than the height of the pipeline.

[0010] In some embodiments, a lifting ring is provided on the first side plate and / or the second side plate.

[0011] In some embodiments, rollers supporting the ground are provided at the ends of the first side plate and the second side plate.

[0012] In some embodiments, the lengths of both the first side plate and the second side plate are greater than the height of the insertion rod.

[0013] In some embodiments, a support guide wheel is provided above the cover plate, and guide wheels are provided on the first side plate and the second side plate. The tension rope is a closed loop, and the loop is wrapped around the guide wheel and the support guide wheel.

[0014] In some embodiments, a lifting device is supported between the support guide wheel and the cover plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The temporary pipeline protection device of this invention consists of multiple rotating plates connected together. Using tension ropes, the first and second side plates bend downwards relative to the cover plate, forming an arched structure that covers the pipeline. By adjusting the length of the tension ropes, the height of the cover plate above the ground is changed, thus adapting to the protection of pipelines of different diameters. Adjusting the length of the tension ropes allows the first and second side plates and the cover plate to be unfolded into a flat plate shape or folded together, adapting to different storage or transportation needs.

[0022] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.

[0023] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0024] like Figure 1 , 2 As shown in Figure 3, a temporary pipeline protection device includes a cover plate 3 located above the pipeline 12. The two opposite ends of the cover plate 3 are rotatably connected to a first side plate 1 and a second side plate 2 via hinges 4. A guide wheel 5 is provided on the cover plate 3 above the pipeline 12. A tension rope 6 is connected between the first side plate 1 and the second side plate 2, passing over the guide wheel 5. The guide wheel 5 provides support and guidance for the movement of the tension rope 6.

[0025] The length of the tension rope 6 is set so that the first side plate 1 and the second side plate 2 are close to each other, that is, the angle between the first side plate 1 and the second side plate 2 and the cover plate 3 is less than 180 degrees. This causes the first side plate 1 and the second side plate 2 to bend downward relative to the cover plate 3, forming an arch-like structure. The ends of the first side plate 1 and the second side plate 2 are supported on the ground, so that they can cover the pipeline 12 and provide temporary protection. The tension rope 6 can be fixedly connected to the first side plate 1 and / or the second side plate 2 by a locking mechanism. For example, a guide ring 7 can be provided on the side of the first side plate 1 and / or the second side plate 2. The tension rope 6 slides through the guide ring 7. A U-shaped buckle 8 is fixed on the tension rope 6 to lock the guide ring 7. By adjusting the position of the U-shaped buckle 8, the distance between the first side plate 1 and the second side plate 2 is changed, that is, the height of the cover plate 3 from the ground is changed, so as to adapt to the protection of pipelines 12 of different thicknesses. The tension rope 6 usually has good elasticity, which helps to cushion the pressure on the cover plate 3.

[0026] Since the first side plate 1, the second side plate 2 and the cover plate 3 can rotate relative to each other, when the tension rope 6 is completely released or removed, the first side plate 1, the second side plate 2 and the cover plate 3 unfold into a flat plate shape. Of course, if the tension rope 6 is tightened, the first side plate 1, the second side plate 2 and the cover plate 3 can be brought closer together, thus adapting to different storage or transportation needs.

[0027] The tension rope 6 can be a steel wire rope or a chain, as long as it is a flexible tension device.

[0028] Furthermore, in this embodiment, a plug rod 9, capable of being inserted into the ground, is fixed below the cover plate 3 on both sides of the pipeline 12. A sliding sleeve 10 is slidably fitted onto the plug rod 9, and the guide wheel 5 is disposed on the sliding sleeve 10. The lower end of the plug rod 9 is pointed, allowing it to be inserted into the ground during use, thereby fixing the device. The lower end of the sliding sleeve 10 is provided with a support part for supporting the ground. This support part is a support body with a large contact area with the ground; in this embodiment, it is an annular gasket 11, so that the sliding sleeve 10 can be supported on the ground. The support of the ground increases the support strength of the guide wheel 5 for the tension rope 6, improving the stability of the device. The height of the support part from the guide wheel 5 is greater than the height of the pipeline 12, so that the tension rope 6 always passes over the pipeline 12.

[0029] A lifting ring 13 is provided on the first side plate 1 and / or the second side plate 2. In this embodiment, both the first side plate 1 and the second side plate 2 are provided with lifting rings 13. The lifting ring is located on the surface of the side plate. By lifting the lifting ring 13 upward, the side moves the cover plate 3 upward, and at the same time, the tension rope 6 is pulled, thereby making the tension rope 6 taut. This causes the tension rope 6 to push the sliding sleeve 10 downward. This not only helps the device to pull out the insertion rod 9 by providing downward reverse support, but also prevents the soil brought out when the insertion rod 9 is pulled out by the pressure of the pad 11 under the sliding sleeve 10. This not only avoids damage to the ground, but also helps to clean the insertion rod 9.

[0030] The ends of the first side plate 1 and the second side plate 2 are provided with rollers 14 that support the ground, which facilitates the movement of the device along the ground. The lengths of the first side plate 1 and the second side plate 2 are both greater than the height of the insertion rod 9. Thus, when the first side plate 1 is brought close enough to the second side plate 2, the lower end of the insertion rod 9 can be lifted off the ground, which facilitates the movement of the protective device along the ground.

[0031] Example 2 like Figure 4 ,5 As shown, unlike the previous embodiment, a support guide wheel 15 is provided above the cover plate 3, and guide wheels 16 are provided on the first side plate 1 and the second side plate 2. The tension rope 6 is a closed loop, which is looped on the guide wheel 16 and the support guide wheel 15, thus eliminating the need for buckles. A lifting device 17 is supported between the support guide wheel 15 and the cover plate 3. The height of the support guide wheel 15 relative to the cover plate 3 is adjusted by the lifting device 17, thereby adjusting the angle of the first side plate 1 and the second side plate 2 relative to the cover plate 3, thereby controlling the tension or relaxation of the tension rope 6 relative to the guide wheel 5. When no heavy object passes over the protective device, when the support guide wheel 15 is raised, the tension rope 6 can be tensioned and push the sliding sleeve 10 downward to pull up the insertion rod 9. The lifting device 17 can be, for example, a hydraulic cylinder, a pneumatic cylinder, a screw lifting mechanism, etc.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
