[0002] In the field of pipeline engineering, the installation of elbows is a common and crucial construction step. Elbows are mainly used to change the flow direction of pipelines to adapt to different pipeline layout requirements. However, in the actual installation process of elbows, due to the weight and shape of the pipes themselves, as well as the influence of the installation environment, achieving a stable connection and precise installation of two elbows often faces many difficulties.

[0003] The installation of elbow pipes mainly relies on manual support and simple auxiliary tools for positioning. Manual support is not only labor-intensive but also makes it difficult to ensure the stability of the pipes during the connection process, easily leading to pipe swaying and misalignment, resulting in low connection accuracy and affecting the overall performance and service life of the pipeline system. Therefore, a connection device for elbow pipe installation is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 The connecting device for installing elbow pipe in this embodiment includes a top plate 1, fixing rods 2 fixedly connected to the four corners of the bottom of the top plate 1, and a bottom plate 3 fixedly connected to the bottom ends of the fixing rods 2 on the front and rear sides. The top of the top plate 1 is provided with a positioning component for stably connecting the two pipes to be installed.

[0025] Please see Figure 1 In this embodiment, the positioning assembly includes a support plate 4 fixedly connected to the top of the top plate 1. A transmission rod 5 is rotatably connected to the inner side of the support plate 4. Two transmission gears 6 are fixedly connected to the outer side of the transmission rod 5. A driven gear 7 meshes with the bottom of the transmission gear 6. A threaded rod 8 is fixedly connected to the inner side of the center of the driven gear 7. A threaded block 9 is threadedly connected to the outer side of the threaded rod 8. A connecting block 10 is fixedly connected to the bottom of the threaded block 9. Two first positioning plates 11 are fixedly connected to the bottom of the connecting block 10. Two electric push rods 12 are fixedly connected to the bottom of the top plate 1. A second positioning plate 13 is fixedly connected to one end of the movable rod of the electric push rod 12.

[0026] Specifically, the bottom left and bottom right sides of the base plate 3 are fixedly connected with movable wheels 14, and the movable wheels 14 are equipped with brakes.

[0027] It should be noted that the brake on the movable wheel 14 can stop the movable wheel 14 from rotating after the device has been moved to a suitable installation position, thereby firmly fixing the entire connection device in the installation position and preventing displacement of the device during subsequent pipeline connection and installation, thus ensuring the stability and accuracy of the installation process.

[0028] Specifically, a rotating handle 501 is fixedly connected to the left end of the transmission rod 5, and two transmission gears 6 are located on the left and right sides of the support plate 4, respectively.

[0029] It should be noted that the rotating handle 501 is designed to facilitate the operator to rotate the transmission rod 5. The rotation of the transmission rod 5 can be achieved by manually applying external force, making the operation simple and easy to control.

[0030] Specifically, connecting plates 15 are fixedly connected to both the left and right sides of the top plate 1. The right end of the transmission rod 5 is rotatably connected to the left side wall of the right connecting plate 15. A support rotating hole adapted to the transmission rod 5 is opened on the inner side of the left connecting plate 15.

[0031] It should be noted that this connection method ensures that the transmission rod 5 remains stable during rotation, reduces swaying and offset, guarantees the smoothness and accuracy of transmission, and thus ensures the normal operation of the entire positioning assembly.

[0032] Specifically, the left end of the left threaded rod 8 is rotatably connected to the right side wall of the left connecting plate 15, and the right end of the left threaded rod 8 is rotatably connected to the left side wall of the support plate 4. The left end of the right threaded rod 8 is rotatably connected to the right side wall of the support plate 4, and the right end of the right threaded rod 8 is rotatably connected to the left side wall of the right connecting plate 15.

[0033] It should be noted that the threaded rod 8 is rotatably connected to the connecting plate 15 and the support plate 4 at both ends, respectively, and can withstand the force generated when the threaded block 9 moves on the threaded rod 8, ensuring that the threaded rod 8 will not bend or shake during rotation, and ensuring that the threaded block 9 can move smoothly and accurately along the threaded rod 8, thereby achieving precise position adjustment of the first positioning plate 11.

[0034] Specifically, the two electric push rods 12 are arranged sequentially along the front-rear direction of the connecting block 10.

[0035] It should be noted that this configuration allows the pipes on both the front and rear sides to be subjected to pressure from the second positioning plate 13, thereby enhancing the positioning effect of the pipes.

[0036] Specifically, the inner side of the top plate 1 has two sliding openings that are adapted to the connecting block 10, and the two sliding openings are located on the left and right sides of the electric push rod 12, respectively.

[0037] It should be noted that the two sliding ports are located on the left and right sides of the electric push rod 12, respectively. This layout makes reasonable use of space and avoids interference between the sliding ports and the electric push rod 12, ensuring the compactness and coordination of the entire device structure.

[0038] Specifically, the two first positioning plates 11 on the left are arranged sequentially along the front-back direction of the left connecting block 10, and the two first positioning plates 11 on the right are arranged sequentially along the front-back direction of the right connecting block 10.

[0039] It should be noted that this layout allows the two front first positioning plates 11 to clamp the front pipe, while the two rear first positioning plates 11 clamp the rear pipe.

[0040] Specifically, rubber pads 16 are fixedly connected to the right side of the left first positioning plate 11, the left side of the right first positioning plate 11, the bottom of the second positioning plate 13, and the top of the base plate 3.

[0041] It should be noted that the rubber pad 16 can increase the friction between the rubber pad and the pipe contact surface, prevent the pipe from sliding during the positioning process, and improve the stability of the positioning.

[0042] Specifically, a reserved gap is provided between the opposite sides of the front and rear bottom plates 3.

[0043] It should be noted that the reserved gap can prevent the base plate 3 from interfering with the installation of the pipes, making it easier for operators to operate and adjust the pipes, thus improving installation efficiency.

[0044] The working principle of the above embodiments is as follows:

[0045] Two pipes are placed on the rubber pads 16 of the base plates 3 on the front and rear sides respectively, and the connecting ends of the two pipes are aligned. The operator rotates the rotating handle 501 on the left end of the transmission rod 5, causing the transmission rod 5 to rotate. The rotation of the transmission rod 5 drives the two transmission gears 6 on its outer side to rotate synchronously. Since the transmission gears 6 mesh with the driven gears 7, the driven gears 7 rotate accordingly. The rotation of the driven gears 7 drives the threaded rod 8 fixed on its inner side to rotate. The rotation of the threaded rod 8 causes the threaded block 9, which is threadedly connected to its outer side, to move along the threaded rod 8. The movement of the threaded block 9 causes the connecting block 10 at its bottom to move in the sliding groove on the inner side of the top plate 1. The movement of the connecting block 10... The two first positioning plates 11 at the bottom of the top plate 1 are moved. At this time, the two first positioning plates 11 on the front side clamp the pipe on the front side, and the two first positioning plates 11 on the rear side clamp the pipe on the rear side. The rubber pads 16 on the first positioning plates 11 are used to initially clamp and position the pipe. The electric push rods 12 on the left and right sides at the bottom of the top plate 1 are activated. The movable rod of the electric push rod 12 extends and drives the second positioning plate 13 at its bottom to move downward, so that the rubber pads 16 at the bottom of the second positioning plate 13 contact the top of the corresponding pipe, and further position and fix the pipe. At this time, the operator can carry out the pipe docking and installation work.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
