In the process of lifting the pipeline, the pipeline is rotated, and the ball is driven to rotate to reduce the friction of the pipeline during the lifting process. When the pipeline is lifted, the fixed frame 1 is pushed to move on the upper end of the excavated ditch through the moving wheel 7, the brake universal wheel 8 and the movable frame 9.

[0038] A control panel is installed on the front side of the fixed frame 203, a top cover is installed on the top of the fixed frame 203, a docking round opening is opened at the rear end of the right side of the fixed frame 203, the battery 204 and the single-phase motor 201 are electrically connected to the control panel, the battery 204 and the single-phase motor 201 are electrically connected, a reinforcing rib layer is installed on the outside of the movable belt 205, the docking joint 208 is made of alloy material, and a limited position opening is opened in the middle of the docking joint 208;

[0039] The specific implementation is as follows: the strength and life of the joint 208 during use are increased by using alloy material, and the interior of the fixed frame 203 can be inspected and repaired by removing the top cover.

[0040] The adjustment mechanism 3 also includes a movable support rod 304, a movable notch 305, a movable adjustment rod 306, a movable through hole 307, a limit circular hole 308, an operation limit rod 309, a limit spring 310 and a mounting through slot 311.

[0041] The specific implementation method is as follows: when performing construction work on the pipeline laying trenches of different widths, the operating limit rod 309 is pulled downward to separate the top of the operating limit rod 309 from the inside of the limit circular opening 308, and during the movement of the operating limit rod 309, the limit spring 310 is stretched. When the top of the operating limit rod 309 is separated from the inside of the limit circular opening 308, the movable adjustment rod 306 loses its restraining force, and then the movable frame 9 is pulled to move to the side away from the fixed frame 1, and the movable adjustment rod 306 is driven to slide in the inner cavity of the movable groove 305. When the movable frame 9 moves, the movable sleeve 301 is driven to slide outside the fixed bar 302 through the movable support rod 304, and the movable support rod 304 can also play a supporting role.

[0047] The specific implementation method is as follows: when laying the pipeline, the fixed arc ring 502 is moved to the middle of the top of the pipeline to be placed, and then the servo motor 509 is started to drive the collecting roller 508 to rotate in the inner cavity of the installation frame head 504, so that the limiting rope 505 is in a relaxed state, and the limiting arc ring 503 loses its restraining force, and the limiting arc ring 503 is pushed downward by the fixed spring 507 in a compressed state, so that the limiting arc ring 503 is moved to the bottom end of the pipeline, so that the fixed arc ring 502 and the limiting arc ring 503 are fitted to the outside of the pipeline to fix the pipeline, and when the retractable roller 206 rotates, the pulling rope 501 is collected and wound, driving the fixed arc ring 502, the limiting arc ring 503 and the fixed pipeline to move upward, and when the pipeline is placed, the servo motor 509 is started to drive the collecting roller 508 to rotate, the limiting rope 505 is wound and collected, and the limiting arc ring 503 is driven to the inner cavity of the collecting slot 506.

The movable push rod 605 is installed with a limiting sleeve block 602 at one end away from the fixed cylinder 603. A T-shaped structure is formed between the movable push rod 605 and the limiting sleeve block 602. A docking port is provided at the front end of both sides of the limiting sleeve block 602. The double-headed electric push rod 601 is electrically connected to the control panel and the battery 204. The battery 204 is electrically connected to the control panel. The fixing rope 604 is installed at the top and bottom ends of the double-headed electric push rod 601. The end of the fixing rope 604 away from the double-headed electric push rod 601 passes through one side of the fixed cylinder 603 and is connected to one side of the movable push rod 605. The end of the movable push rod 605 away from the limiting sleeve block 602 is installed with a mounting spring 606.

[0049] The specific implementation is as follows: when the pipeline is moved, the double-headed electric push rod 601 is started to drive the fixed rope 604 to move. When the fixed rope 604 moves, it drives the movable push rod 605 to slide in the inner cavity of the fixed tube 603. When the movable push rod 605 slides, it drives the installation spring 606 to stretch. Later, the movable push rod 605 and the limiting sleeve 602 are reset by the stretched installation spring 606. When the movable push rod 605 drives the limiting sleeve 602 to move, the limiting sleeve 602 is contacted and squeezed with the outside of the retracting roller 206, and the retracting roller 206 is squeezed and limited. By providing the notches 207 on the outside of both sides of the retracting roller 206, the friction force when contacting with the outside of the limiting sleeve 602 is increased. When the retracting roller 206 is limited and fixed, the stability of the movable belt 205 when fixing the pipeline can be improved, so as to avoid excessive swinging during movement after the pipeline is fixed, which may cause the pipeline to fall.

[0050] Working principle: When the present invention is constructing a pipeline, the docking joint 208 is pulled to drive the movable belt 205 to move, so that the movable belt 205 passes through the bottom end of the pipeline to be constructed, and then the docking joint 208 is docked with the inner cavity of the docking recess 405, and the docking joint 208 is temporarily fixed through the mutual magnetism between the fixed magnetic blocks 406, and the docking joint 208 is contacted with the touch switch 407, and the multi-section electric push rod 402 and the alarm inside the control panel are started at the same time, and the staff is informed through the alarm that the fixation is completed, and the multi-section electric push rod 402 drives the movable limit block 404 to move to the side away from the installation recess 403, so that the movable limit block 404 passes through the limit opening and docks with the inner cavity of the support opening, then the docking joint 208 and one end of the movable belt 205 are fixed, and then the single-phase motor 201 is started to drive the retractable roller 206 to rotate, and the movable belt 205 is wound and retracted. When the movable belt 205 passes through the bottom end of the pipeline, the retractable roller The rotation of 206 collects and wraps the movable belt 205, and lifts the pipeline. In the process of lifting the pipeline, the pipeline is rotated, and the ball is driven to rotate to reduce the friction of the pipeline during the lifting process. When the pipeline is lifted, the fixed frame 1 is pushed to move on the upper end of the dug ditch through the moving wheel 7, the brake universal wheel 8 and the movable frame 9. When the pipeline moves to the laying position, the single-phase motor 201 is started to drive the retracting roller 206 to rotate, so that the movable belt 205 is in a relaxed state, and the pipeline loses its restraining force and moves downward. When the pipeline moves to the position, the double-headed electric push rod 601 is started to drive the movable limit block 404 to move, so that the movable limit block 404 is separated from the inside of the limit opening, so that the joint 208 loses its restraining force, and then the single-phase motor 201 drives the retracting roller 206 to rotate, and the movable belt 205 is wound and collected. In the process of collecting, the movable belt 205 moves away from the bottom of the pipeline to complete the laying of the pipeline;

[0051] When laying the pipeline, the fixed arc ring 502 is moved to the middle of the top of the pipeline to be placed, and the servo motor 509 is started to drive the collecting roller 508 to rotate in the inner cavity of the installation frame head 504, so that the limiting rope 505 is in a relaxed state, and the limiting arc ring 503 loses its restraining force, and the limiting arc ring 503 is pushed downward by the fixed spring 507 in a compressed state, so that the limiting arc ring 503 is moved to the bottom end of the pipeline, so that the fixed arc ring 502 and the limiting arc ring 503 are fitted to the outside of the pipeline to fix the pipeline, and when the retractable roller 206 rotates, the pulling rope 501 is collected and wound, driving the fixed arc ring 502, the limiting arc ring 503 and the fixed pipeline to move upward, and when the pipeline is placed, the servo motor 509 is started to drive the collecting roller 508 to rotate, the limiting rope 505 is wound and collected, and the limiting arc ring 503 is driven to move to the inner cavity of the collecting slot 506, when When the limiting arc ring 503 moves, it squeezes the fixed spring 507, so that the limiting arc ring 503 is separated from the bottom end of the pipeline, so that the pipeline loses its restraint and is placed. When the pipeline is moved and placed for construction in a narrow space, the double placement and lifting can improve the stability and safety of the construction operation, and can also adapt to the narrow construction environment, improve the efficiency of the construction operation, and avoid the use of large-scale construction equipment when working in a narrow space. Even if auxiliary equipment is used for construction, the operating space of the construction will still be limited. If the auxiliary equipment has a demand for operating space, it cannot be completely separated from the outside of the pipeline after placement, which will damage the construction environment. Not only does it reduce the efficiency of pipeline construction in a narrow space, it can also cause damage to the construction environment or even landslides. Rework is required at a later stage, which prolongs the construction period and increases the cost of construction.
