Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a supporting device for installing a large pipeline. Background Art

[0002] With the rapid development of urban construction, urban water consumption is increasing day by day. Underground integrated pipe corridors have become an important part of urban water supply. Their convenience, supply and other advantages are constantly highlighted, effectively alleviating the low pressure of urban water supply. However, the construction speed of urban underground integrated pipe corridors is accelerating, the scale is expanding, the functional requirements are becoming more and more perfect, the pipe diameter is getting larger and larger, the technical difficulty of pipe hoisting and transportation is getting greater and greater, and the quality of pipe docking and welding is difficult to be effectively guaranteed. In order to solve this problem, the use of hydraulic forklifts to transport pipes can safely and effectively transport pipes to designated locations, the use of hydraulic jack sets can effectively improve the efficiency of pipe docking, and the use of welding robots can effectively guarantee the welding quality.

[0003] The existing equipment has the following disadvantages: when welding the pipeline, the connection points at both ends of the pipeline need to be aligned. During the actual installation of the pipeline, it is found that when the installation height of the pipeline is adjusted by the hydraulic jack set on the forklift, the adjustment range of the pipeline is large. After the pipeline to be installed and the fixed pipeline are preliminarily positioned, it is only necessary to fine-tune the installation height of the pipeline. However, the hydraulic jack set on the forklift cannot be used to observe the changes in the installation height of the pipeline at close range during adjustment. Two workers are required to cooperate in the operation, resulting in low efficiency in pipeline positioning, thereby affecting the installation efficiency of the pipeline.

[0004] Therefore, the present application now proposes a support device for large-scale pipeline installation to solve the above-mentioned problems. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model measures and lays out at the construction site, determines the installation position where the temporary pier needs to be installed, and then hoists the pipeline on the supporting unit at the upper end of the forklift through the hoisting equipment. During transportation, two forklifts are set for simultaneous transportation, and the two forklifts are controlled to travel slowly. To prevent side slipping, the forklift and the pipeline can be temporarily bundled with straps and transported to the pipeline placement position. The pipeline to be installed and the fixed pipeline are then aligned by the forklift, and the forklift is pulled back and forth to align the front and back positions of the two pipelines.

[0038] It should be noted that, during work, measurements and layout are carried out at the construction site to determine the installation position where the temporary pier needs to be installed, and then the pipeline 1 is hoisted on the support unit 4 at the upper end of the forklift 3 by means of lifting equipment. During transportation, two forklifts 3 are set up for simultaneous transportation, and the two forklifts 3 are controlled to move slowly. To prevent side slipping, the forklift 3 and the pipeline 1 can be temporarily bundled with straps and transported to the placement position of the pipeline 1. Then, the forklift 3 is used to align the pipeline 1 to be installed with the fixed pipeline 1, and the forklift 3 is pulled forward and backward to align the front and rear positions of the two pipelines 1. Then, the installation height of the pipeline 1 is adjusted by the hydraulic device on the forklift 3, and then the installation height of the pipeline 1 is fine-tuned by the adjustment member 45 on the support unit 4, so that the fine-tuning process of the installation height of the pipeline 1 is smoother and more accurate.

A moving groove 431 for the adjusting member 45 to move is provided at the position of the top frame 43 corresponding to the adjusting member 45, and the adjusting member 45 is symmetrically arranged on the top frame 43.

[0040] With this design, the pipe 1 is placed on the support 44, and then the support 44 is movably arranged, so that the pipe 1 can be easily moved on the upper end of the top frame 43, and then the distance between the two pipes 1 can be adjusted, so that the two pipes 1 can be fitted together for the next step of welding.

[0041] In one embodiment, the adjusting member 45 includes a plurality of fixed rods 452 fixed inside the movable groove 431, a guide rod 451 sleeved on the fixed rod 452, a sliding block 453 fixedly sleeved on the lower part of the guide rod 451, and a lifting member arranged on the sliding block 453 for adjusting the installation height of the pipeline 1, and a fixing groove 432 for installing the fixing rod 452 is opened at the position of the top frame 43 corresponding to the fixed rod 452.

[0042] This design, see Figure 4 as well as Figure 6-8, insert the two sets of adjusting members 45 into the movable groove 431 at the upper end of the top frame 43 respectively, each set of adjusting members 45 includes two guiding rods 451, insert the guiding rods 451 into the movable groove 431, the guiding rods 451 fit the inner wall of the movable groove 431, and then insert the fixing rod 452 into the fixing groove 432, and the fixing rod 452 passes through the guiding rods 451, and the guiding rods 451 are fixed inside the movable groove 431. After the installation height of the pipeline 1 is roughly adjusted, the installation height of the pipeline 1 is fine-tuned by the lifting member installed on the guiding rods 451, which can facilitate the staff to adjust the installation height of the pipeline 1 at a close distance, thereby improving the alignment efficiency of the pipeline 1. After the installation position of the pipeline 1 is adjusted, automatic welding by a robot is adopted, and the welding slag should be knocked off in time with a hammer after the connection is completed.

The support 2 is divided into a vertical plate 21, a horizontal plate 22 and a bottom plate 23 fixed at the lower end of the vertical plate 21. After the support 2 is solidified as a whole, the limit block 24 is fixed on the horizontal plate 22 to limit the pipeline 1 on the horizontal plate 22. When the entire support 2 is installed, the temporary pier is removed.

[0051] In a specific embodiment, the forklift 3 includes a lifting plate 31 for placing a base frame 41, a handle 32 rotatably arranged on one side of the lifting plate 31, a hydraulic lifting device 33 arranged between the handle 32 and the lifting plate 31 for driving the lifting plate 31 to move up and down, and a steering wheel 34 arranged on the lifting plate 31 below the hydraulic lifting device 33, and a walking wheel 35 is arranged on the side of the lower end of the lifting plate 31 away from the steering wheel 34.
