Building water supply and drainage construction is an important part of building construction. During the water supply and drainage construction, it is necessary to weld the pipes to ensure the normal operation of the pipeline system. When welding the pipes, a pipe docking device is required. The pipes to be welded are docked by the docking device, so as to facilitate the welding operation.

The patent name disclosed in the prior art with announcement number "CN111716070A" is "A pipe docking device for construction and its use method". A fixing ring is connected to the docking clamping adjustment mechanism, and locking and fixing devices are symmetrically arranged on both sides of the fixing ring. After the position distance between the first support frame and the second support frame is adjusted, the pipe is locked and fixed in position by the locking and fixing device, and the center lines of the two docking pipes are aligned. In this process, the movable column is pressed, and then the extrusion column and the arc extrusion plate are pushed to squeeze and fix the side of the pipe. Then, the second handle is rotated, and the second handle drives the sleeve ring to rotate, so that the arc extrusion groove in the sleeve ring squeezes the T-shaped movable block in the fixed convex ring, so that the T-shaped movable block is clamped in the annular groove on the side of the movable column. At the same time, the second movable block arranged in the sleeve ring is clamped in the arc fixing block, so that the position of the sleeve ring is fixed, and the clamping and fixing of the arc extrusion plate is realized;

The patent title disclosed in the prior art with the announcement number "CN113183062A" is "A Pipeline Auxiliary Docking Device for Construction". One end of the original fixed pipe to be repaired is placed inside the fixed positioning seat, and the gear ring inside the fixed positioning seat is rotated by the relevant driving device, the gear ring drives the rotating ring to rotate, the rotating ring drives the gear plate to rotate, the gear plate is engaged with the gear one, drives the gear one to rotate, the gear one drives the sleeve to rotate, the thread inside the sleeve is engaged with the thread on the upper end of the clamp rod, drives the clamp rod to move, the clamp rod will move toward the surface of the pipe and engage with the pipe The surfaces of the original pipe to be repaired are contacted, and the clamping rods cooperate with each other to clamp and fix the pipe inside the fixed positioning seat, and the new pipe is placed inside the movable positioning seat. Similarly, the new pipe is clamped and fixed inside the movable positioning seat by using the movable positioning seat. At this time, the driving screw is rotated by the relevant driving device, and the driving screw is engaged with the threaded ring on the lower surface of the sliding seat to drive the sliding seat to move. The sliding seat drives the new pipe to move toward the direction of the original pipe to be repaired through the movable positioning seat, and the new pipe is moved to the position of the pipe to be repaired, so as to perform the docking operation between the pipe to be repaired and the new pipe;

Although the above-mentioned method can accurately position the pipeline through the coordinated use of the gear ring and the rotating ring, the coordinated use of the gear plate and the gear one, the coordinated use of the sleeve and the clamping rod, the coordinated use of the clamping rods, and the coordinated use of the movable positioning seat and the fixed positioning seat, so as to facilitate the docking operation of the pipeline, it is necessary to first control the movement of the clamping rod in the fixed positioning seat to clamp and fix the pipeline, and then control the movement of the clamping rod in the movable positioning seat to clamp and fix the pipeline. The clamping rod in the fixed positioning seat and the clamping rod in the movable positioning seat cannot be controlled at the same time, which makes the operation cumbersome, and cannot quickly perform synchronous self-positioning, and then makes the positioning and docking efficiency of the entire docking device slow;

Therefore, we propose a self-positioning pipe docking device for building construction to solve the above-mentioned problems.

The inner wall of the bottom surface of the base body 1 is provided with a limited sliding groove 101, and the first vertical plate 4 is slidably connected to the inside of the limited sliding groove 101. The interior of the second regulating rod 6 is a hollow structure, and the inner wall of the second regulating rod 6 is a rectangular structure; the inner ends of the second threaded rod 5 are all rectangular structures, and the thread directions of the left and right sides of the first threaded rod 3 are opposite, and the thread directions of the outer sides of the two second threaded rods 5 are opposite.

The two control components 7 move inward synchronously through the cooperation of the first vertical plate 4 and the second threaded rod 5, and the control component 7 is a funnel-shaped structure; two positioning blocks 71 are symmetrically installed on the inner side of the control component 7.

Two positioning grooves 91 are symmetrically formed on the outer side of the positioning ring 9, and the positioning blocks 71 are slidably connected inside the positioning grooves 91;

First, manually insert the two pipes into the two positioning rings 9 respectively, then connect the right end of the second threaded rod 5 on the right side to the external motor through a coupling, and then the motor drives the second threaded rod 5 to rotate. At this time, the second threaded rod 5 drives the second regulating rod 6 to rotate, and the second regulating rod 6 drives the second threaded rod 5 on the left side to rotate together, so that the two second threaded rods 5 rotate at the same time to drive the second vertical plate 8 connected to the outer thread to move inward.

Specifically, referring to Figures 1-3 and 5 and Figures 8-9, the inner end of the positioning ring 9 is rotatably connected to the outer side of the mounting plate 11, and the outer key of the mounting plate 11 is connected to the second transmission gear 111; the outer key of the second threaded rod 5 is connected to the first transmission gear 51, and the upper part of the first transmission gear 51 is meshed and connected to the second transmission gear 111. Four groups of connecting rods 141 are installed with screws at equal intervals on the inner side of the mounting plate 11, and one end of the connecting rod 141 is engaged and slidably connected with the inner side of the first regulating rod 14, and the groove inside the first regulating rod 14 and the connecting rod 141 are both rectangular structures, and the connecting rod 141 and the first regulating rod 14 are arranged one by one. One end of the first regulating rod 14 is connected to the support ring 12, and the inner side surface of the support ring 12 is grooved with four groups of first rotating columns 132 rotatably connected at equal intervals, and a rotating rod 131 is fixed through the outer side of the first rotating column 132, and a cleaning block 13 with a brush installed on one side is fixed to the outer end of the rotating rod 131, and a first torsion spring 133 is nested and connected to the outer side of one end of the first rotating column 132, and a control rope 18 is wound and connected to the outer side of the other end of the first rotating column 132, and the other end of the control rope 18 is connected to the mounting plate 11, and the cleaning block 13 forms a rotating structure with the support ring 12 through the control rope 18;

First, insert the two pipes into the two positioning rings 9 in sequence, so that one end of the pipe is inserted into the support ring 12 and in contact with the side of the cleaning block 13 with the brush, and then when the second threaded rod 5 rotates to drive the second vertical plate 8 and the control component 7 to move inward to self-position and clamp the pipe, the second threaded rod 5 drives the first transmission gear 51 to rotate together, and the first transmission gear 51 rotates and drives the second transmission gear 111 to rotate. At this time, the second transmission gear 111 drives the mounting plate 11 to rotate, and then the mounting plate 11 drives the support ring 12 to rotate through the cooperation of the first regulating rod 14 and the connecting rod 141, and then the support ring 12 drives the cleaning block 13 to rotate with the center of the support ring 12 as the center, so that the cleaning block 13 can well clean up the impurities at the interface of the pipe;

The two plug-in rods in each group are respectively fitted on the left and right sides of the support ring 12, and the highest point of the plug-in rod is higher than the lowest point of the support ring 12. At this time, the two plug-in rods are respectively on the left and right sides of the support ring 12, which can limit the support ring 12 to prevent the support ring 12 from moving left and right. At this time, the right end of the first threaded rod 3 is connected to the external motor through a coupling, and then the motor drives the first threaded rod 3 to rotate. The rotation of the first threaded rod 3 drives the first vertical plates 4 on the outside of the two ends to move inward. At this time, the first vertical plate 4 drives the positioning ring 9 to move inward, and the first vertical plate 4 drives the second threaded rod 5 to move inward, so that the second threaded rod 5 slides in the second regulating rod 6, thereby making the control assembly 7 and the positioning ring 9 stably drive the internal pipe to move inward, and at this time, the positioning ring 9 drives the mounting plate 11 to move inward together, and due to the limitation of the support ring 12 by the plug-in rod, the mounting plate 11 pushes the connecting rod 141 into the first regulating rod 14, and the control rope 18 is released at the same time. At this time, the first rotating column 132 is automatically driven to rotate through the stored force of the first torsion spring 133, and then the first rotating column 132 drives the rotating rod 131 and the cleaning block 13 to rotate as shown in Figures 2 and 7, and then the positioning ring 9 continues to drive the internal pipe to move inward, so that the docking interfaces of the two pipes abut against each other, and then stops the rotation of the first threaded rod 3, thereby completing the docking work.
