Description

Technical Field

[0001] This invention relates to a suspended protection device for exposed trench pipelines, and particularly to a combined pipeline suspended protection device. Background Technology

[0002] To prevent urban flooding caused by the poor drainage capacity of old drainage pipes after rain, old pipelines need to be upgraded and new drainage pipelines need to be built. The construction methods for existing trenches are mainly open excavation and pipe jacking. For the access of side road pipelines, open excavation is basically used. During the excavation process, many pipelines need to be explored and protected. For trenches with a relatively small span, a suspended protection method is usually used. The suspension facilities used are generally slings, steel bars, etc.

[0003] Whether it's slings or welded steel components, their supporting structures and matching suspension devices are very rudimentary, resulting in poor fixing effects, poor appearance, and inconvenient recycling. Because standards vary and there is no unified device, the quality of pipeline protection is difficult to guarantee, and its stability and safety are somewhat hidden, and its compatibility is relatively poor. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a combined pipeline suspension protection device that is flexible in operation, easy to install and use, and safe and reliable.

[0005] To address the technical problems existing in current construction practices, the present invention adopts the following technical solution:

[0006] This invention discloses a combined pipeline suspension protection device, comprising a crossbeam erected at both ends on the ground on both sides of a trench, and a lifting structure connected to the front and rear sides of the crossbeam. Each lifting structure includes a lifting mechanism connected to the left and right sides of the upper flange plate of the crossbeam, and each lifting mechanism includes a rotating lifting arm composed of a vertical insert plate and a horizontal steel plate. The upper part of the vertical insert plate and the outer end of the horizontal steel plate are rotatably connected by a rotating mechanism. The horizontal steel plate is fixed to the upper flange plate of the crossbeam. The vertical insert plates of each lifting structure are respectively arranged on the left and right sides of the crossbeam. The vertical insert plate has a cavity in the middle. Each vertical insert plate is fixedly connected to a vertical steel plate. Multiple bolt holes are spaced apart vertically on the vertical insert plate. A bolt hole is opened at the top of the vertical steel plate. The upper part of each vertical steel plate is inserted into the cavity of the corresponding vertical insert plate. The bolt holes on the vertical steel plate and the bolt holes on the vertical insert plate are coaxially arranged at a set position. A threaded steel bar arranged in the horizontal direction passes through the bolt holes on the left and right sides arranged on the same axis to fix the left vertical insert plate and the vertical steel plate and the right vertical insert plate and the vertical steel plate together.

[0007] The lower part of each vertical steel plate is rotatably connected to the upper part of the upper plate of a folded plate via a rotating mechanism. The bottom of the upper plate is fixedly connected to a downwardly inclined plate. The bottom of the two folded plates of each lifting structure is rotatably connected to the upper part of a rib via a rotating mechanism. The two folded plates are fixedly connected by bolts passing through bolt holes on the rib.

[0008] Beneficial effects of this invention:

[0009] (1) The present invention increases the flexibility of the device through the rotating mechanism, that is, it can protect a single pipeline or a wire harness. There are no strict requirements on the size of the protected object, and it can be wider than the crossbeam, making it highly applicable.

[0010] (2) The present invention is simple to fix. Installation can be completed by simply tightening the bolts. No hot work is required. The length can be adjusted by inserting scrap threaded steel bars into the existing holes. The device can maintain stability by its own weight. The heavier the pipeline, the tighter the connection.

[0011] (3) This invention can be transferred by folding and reused repeatedly.

[0012] (4) The crossbeam involved in this invention can be combined in various forms to meet the requirements of pipeline suspension.

[0013] (4) All materials involved in this invention are recyclable, green and environmentally friendly, flexible and convenient. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] As shown in the attached drawings, a combined pipeline suspension protection device of the present invention includes a crossbeam 1 erected at both ends on the ground on both sides of a trench. A lifting structure is connected to the front and rear sides of the crossbeam. Each lifting structure includes a lifting mechanism connected to the left and right sides of the upper flange plate of the crossbeam. Each lifting mechanism includes a rotating lifting arm 2 composed of a vertical insert plate and a horizontal steel plate. The upper part of the vertical insert plate and the outer end of the horizontal steel plate are rotatably connected by a rotating mechanism 5. The horizontal steel plate is fixed to the upper flange plate of the crossbeam 1. The fixing method can be bolt fixing, that is, the horizontal steel plate is fixed to the crossbeam 1 with bolts 6. Each lifting structure has vertical insert plates on the left and right sides of the crossbeam. A cavity is provided in the middle of each vertical insert plate. Each vertical insert plate is fixedly connected to a vertical steel plate. Multiple bolt holes are spaced apart vertically on each vertical insert plate. A bolt hole is provided at the top of each vertical steel plate. The upper part of each vertical steel plate is inserted into the cavity of the corresponding vertical insert plate. The bolt holes on the vertical steel plate and the bolt holes on the vertical insert plate are coaxially aligned at a set position. A threaded steel bar arranged horizontally passes through the coaxially aligned bolt holes on the left and right sides to fix the left vertical insert plate and the vertical steel plate, as well as the right vertical insert plate and the vertical steel plate.

[0025] The lower part of each vertical steel plate is rotatably connected to the upper part of the upper plate of a folded plate 8 via a rotating mechanism 5. The bottom of the upper plate is fixedly connected to a downwardly inclined plate. The bottoms of the two folded plates 8 in each lifting structure are rotatably connected to the upper part of a rib plate 9 via a rotating mechanism. The two folded plates are fixedly connected by bolts passing through bolt holes on the rib plate. A pad 4 is installed inside the two folded plates.

[0026] The preferred material for the padding is rubber. The padding material itself has the characteristics of not swelling or reacting when exposed to water, and has a rough surface with a certain degree of elasticity.

[0027] Preferably, the vertical insert plate and the vertical steel plate have a certain gap to ensure that the connection is not affected after sand and gravel enter.

[0028] The crossbeam can be an H-beam or a double-beam, as long as its rigidity meets the requirements of the suspension load.

[0029] The rotating mechanism can be an existing mechanism such as a hinge mechanism. Any mechanical structure used to connect this device and allow relative rotation between the two is within the scope of protection of this patent.

[0030] The method of using this device is as follows:

[0031] Insert the vertical steel plate into the vertical insert plate, adjust the extension length of the vertical steel plate, and after the bottom of the folded plate contacts the pipeline 3, use a sufficiently long threaded steel bar to pass through the bolt holes on both sides of the device to connect the vertical steel plate and the vertical insert plate. The pipeline 3 hangs down naturally and presses on the pad 4, and the pipeline 3 is supported on the pad 4.

[0032] After pipeline 3 is inserted into the device, it maintains longitudinal stability through the weight of the lower half of the device and the pressure exerted by the pipeline. Laterally, due to the pressure of the pipeline on the lower half of the device, friction is generated between the upper and lower parts of the bolt holes and the threaded steel bars. The threads on the surface of the threaded steel bars also prevent them from falling off. After the threaded steel bars are inserted, a triangular stable structure is formed, ensuring that the device itself will not swing violently due to environmental influences. At the same time, the rotating mechanism at the bottom of the device provides the pipeline with a certain amount of room to move, preventing it from being torn or damaged by external forces. The padding material 4 increases resistance and provides cushioning, protecting the pipe from damage or slippage.

[0033] The device can be positioned and fixed on both sides of the open trench. If the retaining structure is steel sheet pile and steel pipe pile, the H-beam can be spot welded to the retaining structure to increase the overall stability. The lifting mechanism is symmetrically fixed by drilling holes in the H-beam and fixing it with bolts. The length of the device is adjusted, and the bottom of the two sets of devices is fixed with bolts. Finally, rubber pads are inserted into the bottom of the pipeline to prevent the pipeline from sliding, and the installation is completed. No hot work is required throughout the process; only the bolts need to be tightened.

[0034] This device is used when underground pipelines are exposed during open trench excavation. If the trench continues to be excavated, the pipelines will be suspended in the air. In this case, the pipelines can be protected by hanging them down and pressing them onto the support 4 of this device. After the protection period, the device can be removed. Workers only need to remove the bolts at one end of the crossbeam, and the entire device will fall off. After removal, it can be folded and reused.

[0035] The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this invention, can make many modifications without departing from the spirit and scope of the claims, and these modifications are all within the scope of protection of this invention.
