[0002] Urban heating refers to the provision of heat energy to urban residents and commercial users through centralized heating systems to meet their needs for winter heating and hot water supply. Such systems typically consist of three main parts: heat sources (such as thermal power plants and boiler rooms), heat networks (pipeline networks that transport heat), and heat user terminals (such as residential buildings and public buildings).

[0003] Urban heating is mainly delivered through pipelines, which are usually laid underground. During the laying process, two pipelines need to be connected by welding. However, inaccurate connection between the two pipelines can affect the welding work, so improvements are needed. Utility Model Content

[0024] The first connecting assembly 5 includes a fixing bracket 51 fixed to the outer wall of the first heating pipe 1. The fixing bracket 51 has a rectangular structure and a rectangular through hole inside. A positioning bolt 52 is threaded onto the outer wall of the fixing bracket 51, and one end of the positioning bolt 52 is connected to the outer wall of the first heating pipe 1. This structure can fix the fixing bracket 51 to the first heating pipe 1 through the positioning bolt 52. A housing 9 is fixedly connected to the bottom of the fixing bracket 51, and a reciprocating ball screw assembly 10 is installed inside the housing 9. This structure can prevent dust from entering the reciprocating ball screw assembly 10 through the housing 9. One end of component 10 is connected to a drive motor 11, and the inner side of the reciprocating ball screw assembly 10 is connected to a first hydraulic cylinder 2. This structure can drive the reciprocating ball screw assembly 10 to rotate automatically via the drive motor 11. During the rotation, the reciprocating ball screw assembly 10 can drive the first hydraulic cylinder 2 to move back and forth, facilitating the adjustment of the position of the second heating pipe 4. The bottom of the fixing frame 51 is slidably connected to the first hydraulic cylinder 2, one end of the first hydraulic cylinder 2 is connected to a second hydraulic cylinder 3, the top of the second hydraulic cylinder 3 is connected to the second connecting assembly 8, and a magnifying glass is fixedly connected to one end of the second connecting assembly 8. 6. The magnifying glass 6 is positioned at the connection point at the top of the first heating pipe 1 and the second heating pipe 4. This structure allows the magnifying glass 6 to magnify the connection point, facilitating closer inspection by staff to ensure proper alignment between the pipes. The second connecting component 8 and the first connecting component 5 form a sliding connection, and their structures are identical. This structure allows the second connecting component 8 and the first connecting component 5 to be fixed to the outer walls of the second heating pipe 4 and the first heating pipe 1, respectively. The position of the second heating pipe 4 is adjusted; a fixing plate 7 is provided inside the second connecting component 8, and a spirit level 12 is provided on the fixing plate 7; this structure allows the levelness of the second heating pipe 4 to be observed through the spirit level 12, and the fixing plate 7 allows the check whether the heights of the first heating pipe 1 and the second heating pipe 4 are level; a spirit level 12 is provided on the top side of the second connecting component 8; the first hydraulic cylinder 2 can push the second connecting component 8 and the second heating pipe 4 to move laterally to adjust their positions, and the second hydraulic cylinder 3 can push the second connecting component 8 and the second heating pipe 4 to adjust their height longitudinally.

[0025] Working principle: When using this urban heating pipeline connection device, firstly, the fixing brackets 51 of the second connecting component 8 and the first connecting component 5 are respectively fitted onto the outer walls of the second heating pipeline 4 and the first heating pipeline 1. Then, the positioning bolts 52 are rotated to fix the fixing brackets 51 to the second heating pipeline 4 and the first heating pipeline 1. After fixing the fixing brackets 51, the positions of the second heating pipeline 4 and the second connecting component 8 are adjusted. During the adjustment, the front-to-back position, lateral position, and height of the second heating pipeline 4 and the second connecting component 8 can be adjusted at one time by using the reciprocating ball screw assembly 10, the first hydraulic cylinder 2, and the second hydraulic cylinder 3. During the adjustment, the docking status of the first heating pipeline 1 and the second heating pipeline 4 can be checked by using the bubble level 12 and the magnifying glass 6 to ensure that the first heating pipeline 1 and the second heating pipeline 4 are accurately docked. After docking, electric welding is performed. Then, the second connecting component 8 and the first connecting component 5 are loosened and moved laterally to the next position for use.
