Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to an overhead pipeline installation device. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. They are made by winding glass fibers with a resin matrix layer by layer onto a rotating mandrel according to process requirements. Their pipe wall structure is rationally designed and advanced, fully utilizing the material's properties. While meeting strength requirements, it improves rigidity, ensuring product stability and reliability. Most existing pipes are buried underground. Connecting the pipe to the sealing sleeve can be done by using bulldozers or other construction machinery to push the other end of the pipe and insert it into the sealing sleeve, making installation relatively convenient. However, some existing pipes are installed overhead, often indoors or in small spaces, making the connection of the sealing sleeves very inconvenient. Therefore, there is an urgent need for installation equipment for overhead pipes. Utility Model Content

[0003] The purpose of this invention is to provide an overhead pipeline installation device that can quickly insert overhead pipelines into a sealing connection sleeve, and is simple and convenient to operate, which can effectively improve pipeline installation efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An overhead pipeline installation device includes a pair of hydraulic cylinders with lugs, two sets of clamps, and a hydraulic pump;

[0006] One clamp can be detachably fixed to the sealing connection sleeve, and the other clamp can be detachably fixed to the pipe;

[0007] The two ends of the hydraulic cylinder with earrings are rotatably connected to two sets of clamps, and the two sets of hydraulic cylinders with earrings are symmetrically arranged.

[0008] Through the above technical solution, the hydraulic pump supplies oil to the hydraulic cylinder with lugs, and the hydraulic cylinder with lugs drives the two clamps to move closer to each other. The clamps drive the pipe to be inserted into the sealing connection sleeve, so that the pipe connection can be made quickly and conveniently.

[0009] The present invention is further configured such that the hydraulic pump is a manual hydraulic pump, which is lightweight, compact, easy to operate, easy to carry, and convenient for on-site construction.

[0010] This invention is further configured such that: the oil outlet of the hydraulic pump is connected to a hydraulic synchronization valve via a main oil pipe, and the hydraulic synchronization valve is connected to the lug-type hydraulic cylinder via a branch oil pipe. By setting the hydraulic synchronization valve, the oil pressure of the two lug-type hydraulic cylinders can be made equal, and the extension and retraction speeds of the two lug-type hydraulic cylinders will not have a speed difference, thereby ensuring the linear movement of the clamp and ensuring that the pipeline is smoothly inserted into the sealing connection sleeve.

[0011] The present invention is further configured such that: the clamp includes a pair of semi-circular clamp plates, and the two ends of the semi-circular clamp plates are provided with wing plates, and bolts are sleeved on the wing plates;

[0012] Both ends of the hydraulic cylinder with earrings are fixed with earrings, which are inserted into the corresponding bolts.

[0013] The installation process of this equipment is as follows: First, place the pair of semi-circular clamps of one of the clamps on both sides of the sealing connection sleeve. Then, use bolts to pass through the wing plates to connect the wing plates. During the bolt installation process, two bolts need to pass through one end of the lug of the hydraulic cylinder with lugs. Then, tighten the screws to fix the clamp to the sealing connection sleeve.

[0014] Then, align one end of the pipe to be installed with the opening of the sealing sleeve and insert it slightly.

[0015] Then, place the semi-circular clamp plate of another clamp on both sides of the pipe, and connect the flange plates by bolts through the flange plates. Similarly, two of the bolts need to pass through the lugs on the other end of the hydraulic cylinder with lugs. Before tightening the bolts, adjust the positions of the two hydraulic cylinders with lugs so that they are as symmetrical as possible about the pipe axis, and then tighten the bolts to fix the clamp to the pipe.

[0016] The present invention is further configured such that a rubber liner is fixed on the inner wall of the semi-circular hoop. By adding the rubber liner, direct contact and rigid connection between the hoop and the outer wall of the pipe or the outer wall of the sealing sleeve can be avoided, which can effectively play a protective role; the rubber liner can increase the friction between the hoop and the pipe or the connecting sleeve, preventing relative slippage during the later pipe installation process.

[0017] The outstanding effect of this utility model is:

[0018] Compared with existing technologies, the overhead pipeline can be quickly inserted into the sealing connection sleeve by using clamps and hydraulic cylinders. The operation is simple and convenient, which can effectively improve the pipeline installation efficiency.

[0019] The hydraulic pump is a manual pump, which is easy to carry and move, and meets the needs of on-site construction.

[0020] By installing a rubber liner inside the clamp, the pipe fittings can be effectively protected and frictional resistance increased, ensuring the straight insertion of the pipe fittings. Attached Figure Description

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The following is for reference Figures 1 to 2 The embodiments of this utility model are described below:

[0029] An overhead pipeline installation device includes a pair of hydraulic cylinders 2 with lugs, two sets of clamps 3, and a hydraulic pump 4. The oil outlet of the hydraulic pump 4 is connected to a hydraulic synchronizing valve 42 via a main oil pipe 41, and the hydraulic synchronizing valve 42 is connected to the hydraulic cylinders 2 with lugs via branch oil pipes 43. One set of clamps 3 is detachably fixed to a sealing connection sleeve 90, and the other set of clamps 3 is detachably fixed to the pipeline 91. The specifications of the two sets of clamps can be adapted according to suitable pipe fittings.

[0030] The two ends of the hydraulic cylinder 2 with earrings are rotatably connected to two sets of clamps 3, and the two sets of hydraulic cylinders 2 with earrings are symmetrically arranged. The clamp 3 includes a pair of semi-circular clamp plates 31, and the two ends of the semi-circular clamp plates 31 are provided with wing plates 32, and bolts 33 are sleeved on the wing plates 32;

[0031] Both ends of the hydraulic cylinder 2 with earrings are fixed with earrings 21, and the earrings 21 are inserted into the corresponding bolts 33.

[0032] In the actual assembly process, the sealing sleeve is already installed at one end of one of the pipes in the factory, and the other pipe needs to be installed on-site into the other end of the sealing sleeve.

[0033] Installation process: First, place the pair of semi-circular clamps of one of the clamps on both sides of the sealing connection sleeve. Then, use bolts to pass through the wing plates to connect the wing plates. During the bolt installation process, two bolts need to pass through one end of the lug of the hydraulic cylinder with lugs. Then, tighten the screws to fix the clamp to the sealing connection sleeve.

[0034] Then, align one end of the pipe to be installed with the opening of the sealing sleeve and insert it slightly.

[0035] Then, place the semi-circular clamp plate of another clamp on both sides of the pipe, and connect the flange plates by bolts through the flange plates. Similarly, two of the bolts need to pass through the lugs on the other end of the hydraulic cylinder with lugs. Before tightening the bolts, adjust the positions of the two hydraulic cylinders with lugs so that they are as symmetrical as possible about the pipe axis, and then tighten the bolts to fix the clamp to the pipe.

[0036] Then, the hydraulic pump supplies oil to the hydraulic cylinder with the lug. The hydraulic synchronization valve ensures that the flow rate into the two hydraulic cylinders is equal, thereby ensuring the consistency of movement of the two hydraulic cylinders and ensuring the straight insertion of the pipeline.

[0037] As a preferred option, hydraulic pump 4 is a manual hydraulic pump. Manual hydraulic pumps are lightweight and compact, making them easy to operate, carry, and use on-site.

[0038] Preferably, a rubber liner 34 is fixed on the inner wall of the semi-circular hoop 31. By adding the rubber liner, direct contact and rigid connection between the hoop and the outer wall of the pipe or the outer wall of the sealing sleeve can be avoided, which can effectively play a protective role; the rubber liner can increase the friction between the hoop and the pipe or the connecting sleeve, preventing relative slippage during the later pipe installation process.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
