DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be noted that the drawings are only for illustrative purposes, and only represent schematic diagrams, not physical drawings, and cannot be understood as limitations on the present invention; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0030] Here is a unified explanation. Unless otherwise specified, the "transverse" and "longitudinal" mentioned below refer to the width direction of the pipeline construction groove, and the "longitudinal" refers to the length direction of the pipeline construction groove; that is, the length direction of the bell-and-spigot pipe is the "longitudinal" direction, and the direction perpendicular to the length direction of the bell-and-spigot pipe in the horizontal plane is the "transverse" direction.

[0031] See also Figure 1-3In the present embodiment, a grooved socket pipe docking device is disclosed, comprising: a movable base 1, wherein the movable base 1 is used to ensure the movement of the device as a whole; a centering mechanism 2, comprising a base 201 which can be lifted and lowered on the movable base 1 and a centering plate 202 which can be driven to slide along the axial direction of the socket pipe 6 on the base 1. It can be understood that the height of the centering plate 202 can be adjusted by adjusting the height of the base 201 to ensure that the centering plate 202 can be smoothly inserted into the installed upper section of the socket pipe during centering, thereby completing the position confirmation of the centering plate 202. Two sets of support assemblies 3 are arranged on the movable base 1 in opposite directions, and the support assembly 3 includes a support seat 301 arranged on the movable base 1 in a manner that can be driven to move laterally and can be locked, and the support seat 301 is provided with a support surface 301a arranged obliquely relative to the horizontal plane and used to hold up the bell-and-spigot pipe 6. It can be understood that the support surfaces 301a on the two sets of support seats 301 can form an "inverted eight-shaped" support structure, and the bell-and-spigot pipe 6 can be placed on the two support seats 301; because the support seat 301 can be driven to move laterally and can be locked, the movable support By adjusting the position of the support seat 301, the height position of the bell-and-spigot 6 can be adjusted (the closer the two sets of support seats 301 are, the higher the position of the lifted bell-and-spigot 6 is). In this way, by controlling the position of the mobile support seat 301 and cooperating with the centering plate 202, the position of the bell-and-spigot to be connected can be quickly aligned, and then the bell-and-spigot to be connected can be pushed to complete the connection. The movable base 1 is provided with a notch 1a that can make the bell-and-spigot fall to the ground after the support seat 301 is removed and the movable base 1 can be removed. In this way, after the connection is completed, the movable base 1 can be removed to carry out the connection construction at the next position. It is understood that the distance between the bell and spigot 6 and the ground is very small. After the support seat 301 is removed, the bell and spigot 6 can be stably supported by the ground, which will not affect the docking quality; it is understandable that the centering plate 202 is usually slightly smaller than the inner diameter of the bell and spigot 6; the base locking device 4 is arranged on the movable base 1 to complete the position locking of the movable base 1. The base locking device 4 can complete the position locking of the movable base 1 to prevent displacement; the thrust mechanism 5 is arranged on the base 201 to push the bell and spigot to move.
