Description

Technical Field

[0001] The present invention relates to the technical field of pipeline support, in particular to a multi-pipeline support device. Background Art

[0002] The installation of pipes for water supply and drainage, air conditioning cooling water, and firefighting water within high-rise building shafts is characterized by confined working space. This typically requires segmented pipes to be welded together within the shaft. Welding quality is a key component of pipeline installation quality control. Due to the limited working space within the shaft, controlling the gaps, misalignment, and axial dimensional deviations between the different segments of pipe is challenging. Traditionally, pipe joints are welded together with multiple positioning plates, which are then secured in place using manual force or external forces like crowbars. After the joint is complete, the positioning plates are removed, the surface is polished, and an anti-corrosion coating is applied.

[0003] Welding positioning plates on pipelines destroys the parent material structure of the pipelines and greatly reduces the performance of the parent material in the heat-affected zone. The size of the through-weld holes on the positioning plates is too small, which is not convenient for continuous pipe butt welding. In addition, the working space in the shaft is limited, and it is extremely inconvenient to rely on positioning plates to perform pipeline positioning operations. The pipelines in the hoisting state need to be adjusted repeatedly, and it is difficult to accurately dock them into place even after long-term operation. In actual operation, there will be violations such as spot welding and forcible docking with crowbars or jacks. While wasting time and labor, the construction quality of the pipeline cannot be guaranteed. Summary of the Invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0020] Example: Figure 1-3 A multi-pipe support device is shown. This embodiment takes the installation of eight pipes inside a vertical shaft as an example, and includes eight fixing clamps 1, which are respectively installed on the eight pipes. The top of the installed pipe section is placed on the inner lower part of the fixing clamp 1, and the bottom of the pipe section to be installed is placed on the inner upper part of the fixing clamp 1. A rubber sealing ring is provided on the inner surface of the fixing clamp 1.

[0021] Furthermore, the fixing clamp 1 includes a semicircular left clamp and a right clamp, the connection between the left and right clamps being compressed by a fastener 2, i.e., each fixing clamp 1 is compressed by two fasteners 2. The fastener 2 includes a first semicircular fastening seat 3, the straight end of the first semicircular fastening seat 3 being provided with two symmetrical second semicircular fastening seats 4, the curved end of the second semicircular fastening seat 4 being half embedded in the first semicircular fastening seat 3, the straight end of the second semicircular fastening seat 4 being provided with two symmetrical third semicircular fastening seats 5, the curved end of the third semicircular fastening seat 5 being half embedded in the second semicircular fastening seat 4, the two second semicircular fastening seats 4 respectively compress the left and right clamps at corresponding positions, and the contact surface between the third semicircular fastening seat 5 and the fixing clamp 1 is arc-shaped. By superimposing and compressing the three semicircular fastening seats and the arc-shaped contact surface with the fixing clamp 1, the vertical friction between the fastener 2 and the fixing clamp 1 can be effectively improved.

[0022] Furthermore, a rectangular support seat is provided at the lower end of the first semicircular fastening seat 3 , and a support rod 6 is provided on the support seat. The fastener 2 is installed on the support frame 7 through the support rod 6 .

[0023] In order to increase the overall supporting capacity and stability of the supporting device, the support frame 7 is made of angle steel into a frame structure and placed on the periphery of the eight pipes. The interior of the frame structure is provided with an angle steel cross beam and three angle steel longitudinal beams that intersect with each other. Four pipes are installed on both sides of the angle steel cross beam, and adjacent pipes are separated by the angle steel longitudinal beams.

[0024] Furthermore, the support rod 6 is axially movable horizontally via a transmission assembly. Specifically, the transmission assembly includes three laterally extending transmission rods 8, one end of which is fixed with a power gear 9. A first transmission gear 10 is disposed on the outer wall of the support rod 6, and a second transmission gear 11 is disposed at a corresponding position on the outer wall of the transmission rod 8. The second transmission gear 11 is vertically connected to the first transmission gear 10. During operation, the power gear 9 is connected to the motor, and the transmission rods 8 are used to push the support rod 6 horizontally until the clamp 1 is pressed and fixed.

[0025] Furthermore, to improve the fastening capability of the fastener 2, brake gears 12 are fixed to both ends of the transmission rod 8. A movable clip 13 and an inverted T-shaped fixed baffle 14 are provided on the support frame 7. The movable clip 13 is rotatably connected to the inner side of the support frame 7 via a movable bolt 18. The top of the movable clip 13 meshes with the tooth groove of the brake gear 12, and the fixed baffle 14 is positioned below one end of the movable clip 13. In this way, the movable clip 13 and the fixed baffle 14 prevent the transmission rod 8 from rotating.

[0026] Furthermore, six transmission lugs 15 are fixed to the support frame 7, mounted on the ends of the three transmission rods 8. The transmission lugs 15 are provided with transmission holes for the transmission rods 8 to pass through. Sixteen support lugs 16 are also fixed to the support frame 7, mounted on the outer ends of the sixteen support rods 6. The support lugs 16 are provided with support holes for the support rods 6 to pass through. Manual gears 17 are provided on the outer ends of the support rods 6, which can be used to fine-tune the fasteners 2.

[0027] The support device of this embodiment connects the segmented pipes in the vertical shaft through the fixing clamp 1. The connection is convenient, easy, and accurate, and can adapt to pipes of different diameters. The fasteners 2 and the support frame 7 are used to finally fix and permanently support the pipes without damaging the pipe matrix, greatly reducing the difficulty and cost of the operation and improving the construction efficiency and quality of the pipes in the vertical shaft.

[0028] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
