DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. It should be noted that the drawings are only used for illustrative description, and the representation is only a schematic diagram, not a physical diagram, and should not be understood as a limitation on the present application. In order to better illustrate the embodiments of the present application, some components in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. It is understandable for those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.
[0023] Here, it is uniformly stated that "transverse" and "longitudinal" mentioned below refer to the width direction of the pipeline construction trench, and the length direction of the pipeline construction trench, that is, the length direction of the socket pipe is "longitudinal", and the direction perpendicular to the length direction of the socket pipe in the horizontal plane is "transverse".
[0024] Please refer to Figs. 1-3The embodiment discloses a cement socket pipe butt joint auxiliary device, which comprises a movable base 1, a centering mechanism 2 and two groups of support assemblies 3. The movable base 1 is used for ensuring the movement of the device as a whole. The centering mechanism 2 comprises a base 201 and a centering disc 202. The base 201 is arranged on the movable base 1 in a liftable mode, and the centering disc 202 is arranged on the base 1 in a slidable mode along the axis direction of the socket pipe 6. It can be understood that the height of the centering disc 202 can be adjusted by adjusting the height of the base 201, so that the centering disc 202 can be smoothly inserted into the installed socket pipe, and the position of the centering disc 202 is confirmed. The support assembly 3 comprises a support base 301 arranged on the movable base 1 in a drivable transverse moving and lockable mode. The support base 301 is provided with a support surface 301a arranged in an inclined mode relative to the horizontal plane and used for supporting the socket pipe 6. It can be understood that the support surfaces 301a on the two groups of support bases 301 can form an inverted eight-shaped support structure, and the socket pipe 6 can be placed on the two support bases 301. Since the support base 301 can be driven to move transversely and be locked, the height position of the socket pipe 6 can be adjusted by moving the position of the support base 301 (the closer the two groups of support bases 301 are, the higher the position of the socket pipe 6 supported is). The position of the socket pipe to be butt jointed can be quickly aligned by controlling the position of the support base 301 and cooperating with the centering disc 202, and then the socket pipe to be butt jointed is pushed to complete the butt joint. The movable base 1 is provided with a gap part 1a used for enabling the socket pipe to fall to the ground after the support base 301 is moved away and enabling the movable base 1 to be moved away. Thus, the movable base 1 can be moved away after the butt joint is completed, and the butt joint construction at the next position is carried out. It can be understood that the distance of the socket pipe 6 from the ground is very small, and the socket pipe 6 can be stably supported by the ground after the support base 301 is moved away, so that the butt joint quality is not affected. It can be understood that the centering disc 202 is usually slightly smaller than the inner diameter of the socket pipe 6.
[0025] The cement socket pipe butt joint auxiliary device in the structural design can improve the construction efficiency of the cement socket pipe butt joint construction and improve the pipe construction quality. Specifically, the centering mechanism 2 can quickly complete the centering and alignment of the movable base 1 and the last socket pipe. When the socket pipe to be butt jointed is hoisted onto the support assembly 3, the position alignment of the socket pipe can also be quickly completed through the cooperation and adjustment of the centering mechanism 2 and the support assembly 3. Thus, the socket pipe to be butt jointed can be directly pushed into the last socket pipe. The centering disc can play a good guiding role in the butt joint process, ensuring the accuracy of the butt joint. In this way, the construction efficiency and construction quality are improved. Meanwhile, the device does not require multiple people to operate in the trench, and the butt joint is not required to be performed by multiple people supporting the socket pipe, thereby reducing the waste of human resources. Meanwhile, the movable base 1 is provided with a gap portion that can make the socket pipe fall to the ground after the support seat is removed and can move the movable base 1 away. Thus, after the butt joint construction is completed, the support seat 301 is loosened, and the movable base 1 can be moved away for butt joint installation at the next position, thereby ensuring the construction efficiency. At the same time, after the movable support seat 301 is removed, the protruding step at the socket of the socket pipe can be avoided, so that the movable base 1 can be smoothly removed.
[0026] In the embodiment, the movable base 1 includes a bottom plate 101, the support assembly 3 further includes a sliding seat 302 fixed on the bottom plate 101, at least two groups of transversely arranged guide cylinders 302a are fixed on the sliding seat 302, the support seat 301 includes a sliding column 301c and a sliding column 301c fixed on the back of the inclined support plate 301b and slidingly fitted with the guide cylinder 302a, and the support surface 301a is formed on the inclined support plate 301b. Specifically, the sliding seat 302 is welded and fixed on the bottom plate 101, and the guide cylinder 302a is arranged in two groups and adopts a square cylinder structure.

The inclined support plate 301b can stably support the socket pipe, and the cooperation and installation of the sliding column 301c and the guide cylinder 302a can ensure sufficient bearing capacity.
[0027] In the embodiment, a plurality of universal balls 301d for supporting the socket pipe are uniformly arranged on the inclined support plate 301b along the axis direction of the socket pipe 6. By arranging a plurality of universal balls 301d, the socket pipe contacts the universal balls 301d, which can effectively reduce the friction and facilitate the sliding of the socket pipe to complete the butt joint and reduce the risk of jamming. Meanwhile, the plurality of universal balls 301d can stably support the socket pipe and ensure the position accuracy of the socket pipe, thereby further improving the construction efficiency.
[0028] In the embodiment, the first driving electric cylinder 303 is fixedly arranged on the sliding seat 302, and the telescopic end of the first driving electric cylinder 303 is fixedly connected with the inclined support plate 301b.

By adopting the second driving electric cylinders 401, it is beneficial to guarantee the convenience of locking. In use, the position locking of the movable base 1 can be guaranteed by moving the telescopic ends of the second driving electric cylinders 401 to abut to the two side walls of the construction groove. At the same time, the locking effect is good, which is beneficial to guarantee the construction quality.
[0030] In the embodiment, the thrust mechanism 5 is further included, the thrust mechanism includes a third driving electric cylinder 502 and a thrust disc 501 which is arranged on the base 201 and can be driven to slide along the axis direction of the socket pipe 6, and the telescopic end of the third driving electric cylinder 502 is connected with the thrust disc 501 for driving the thrust disc 501 to move.
