[0028] In order to make the above-mentioned purposes, features, and advantages of this utility model more obvious and understandable, the following further details this utility model in conjunction with the attached drawings and specific embodiments.

[0029] Please refer to Figures 1 to 4, this embodiment provides a spatial rainwater steel pipe precise positioning and splicing attitude adjustment device, which includes a vertical support part 4, a horizontal support part 2 and a support foot 6 that are perpendicular to each other. The horizontal support part 2 is arranged at the top end of the vertical support part 4, and the support foot 6 is arranged at the bottom end of the vertical support part 4. The vertical support parts 4 are arranged in pairs, and each pair of vertical support parts 4 corresponds to a horizontal support part 2, and the vertical support parts 4 are arranged at both ends of the horizontal support part 2; a stiffening plate 1 is arranged in the middle of the horizontal support part 2, and inclined support parts are also arranged between the vertical support part 4 and the horizontal support part 2 and between the vertical support part 4 and the support foot 6; it also includes a first lifting lug 10 arranged on the lower surface of the middle part of the horizontal support part 2 and a second lifting lug 8 arranged on the outer peripheral surface of the rainwater steel pipe 7 to be spliced. The first lifting lug 10 and the second lifting lug 8 are movably connected through a flexible spacing adjustment device 9, and the rainwater steel pipe 7 to be spliced is hoisted between the vertically arranged vertical support parts 4 through the flexible spacing adjustment device 9.

[0030] The working principle of this embodiment is as follows: On the basis that the rainwater steel pipes at both ends have been fixed and formed, this embodiment is arranged at both ends of the rainwater steel pipe 7 to be spliced in the middle. The second lifting lugs 8 are fixed at the corresponding positions at both ends of the rainwater steel pipe 7 to be spliced, and the rainwater steel pipe 7 to be spliced is hoisted between the vertically arranged vertical support parts 4 by using the flexible spacing adjustment device 9, and the flexible spacing adjustment device 9 is adjusted to lift the rainwater steel pipe 7 to be spliced to the corresponding height. During the process of aligning the rainwater steel pipe 7 to be spliced with the rainwater steel pipes fixed at both ends, due to the flexible characteristics of the flexible spacing adjustment device 9, the position of the end of the rainwater steel pipe 7 to be spliced can be adjusted arbitrarily with the assistance of manpower, ensuring convenient adjustment of the spatial attitude during the steel pipe installation, precise interface docking, and small overall space occupation of the device, improving the installation quality.

[0031] Specifically, taking the installation of an 8.5m long DN1600mm steel pipe suspended 400mm on a 7% slope as an example:

[0032] A pair of vertically arranged vertical support parts 4 and a corresponding horizontal support part 2 form a gantry, which is convenient for hoisting, fixing and splicing large-diameter steel pipes in a limited space.

[0033] The device mainly consists of the following structures:

[0034] 1. Column: That is, the vertical support part 4, using two I16 steel beams with a length of 3200mm on both sides, and fabricated with an inner net width of 2200mm (the pipe diameter size adds 280mm working surfaces on both sides to ensure that the distance between the column and the rainwater steel pipe 7 to be spliced is at least 280mm).

[0035] 2. Cross bar: That is, the horizontal support part 2, welded to the top of the column with an I16 steel beam. When welding, the web of the column is parallel to the length extension direction of the cross bar, and the web of the cross bar is parallel to the length extension direction of the vertical rod.

[0036] 3. Angle brace: That is, the first inclined support part 3. An I16 steel I-beam is used as the angle brace for reinforcement between the top of the crossbar and the column. The angle brace forms a 45-degree angle with the crossbar, and the installation position is at the 1 / 3 of the crossbar length.

[0037] 4. Stiffener plate 1: Two stiffener plates 1 with a length of 600 mm and a width of 80 mm are added in the middle of the crossbar. After cutting the I16 steel I-beam in the middle to obtain the stiffener plate 1, the flanges of the stiffener plate 1 are welded to both sides of the web of the crossbar.

[0038] 5. Leg: That is, the support foot 6. The bottom of the column uses a double-pin I16 steel I-beam with a length of 2.5 m as the leg, which is welded to the bottom of the column. When welding, the web direction of the column is perpendicular to the length extension direction of the leg to ensure the overall stability.

[0039] 6. Diagonal brace: That is, the second inclined support part 5. Angle steel with a size of 80*80 mm and a thickness of 6 mm is added on both sides of the column as the diagonal brace for reinforcement. The height of the diagonal brace is 1 / 3 of the column height.

[0040] 7. Lifting lug: A D-shaped lifting lug made of Q335C steel with a thickness of 20 mm is welded below the center position of the crossbar, that is, the first lifting lug 10;

[0041] D-shaped lifting lugs made of Q335C steel with a thickness of 20 mm are welded at 1000 mm inward from both ends of the rainwater steel pipe 7, that is, the first lifting lug 10;

[0042] The width of one end of the D-shaped lifting lug connected to the crossbar or the rainwater steel pipe 7 is greater than the width of the other end.

[0043] 8. Chain block: That is, the flexible spacing adjustment device 9. It is suspended in the hanging hole 11 of the first lifting lug 10 on the crossbar, and the hook is used to hook the second lifting lug 8 on the rainwater steel pipe 7 to perform operations such as hoisting in place, attitude adjustment, and splicing.
