In this way, when the rotating member 100 rotates by a corresponding angle, at least two moving assemblies 200, the telescopic member 300 and the picking member 400 can be driven to rotate by corresponding angles, the moving portion 220 is combined with the movement of the moving portion 220 along the first axial direction (as shown in a direction a of fig. 2) of the rotating member 100, so that the telescopic member 300 and the picking member 400 correspondingly connected with the moving portion 220 can be driven to move to a position right above the pipe piece, when the telescopic member 300 directly above the pipe piece is extended, the picking member 400 on the telescopic end 320 is moved to pick up a pipe piece, thereby completing the one-time picking up of at least two pipe pieces, then the telescopic member 300 is retracted, so that the pipe pieces are suspended, and the moving portion 220 is combined with the movement of the moving portion 220 along the second axial direction (as shown in a direction B of fig. 2) of the rotating member 100 (wherein the second axial direction is opposite to the first axial direction, for example, the second axial direction is towards the left), so that the picked up at least two pipe pieces can be moved to a position right, and the picked up at least two pipe pieces can be simultaneously paved on at least two positions by further combining the extending and unloading the telescopic member 300. And, the rotating member 100 only needs to rotate once, each moving part 220 only needs to reciprocate once along the axial direction of the rotating member 100, and the telescopic member 300 only needs to stretch twice and retract once, so that at least two segments can be paved once, the number of times of movement of the rotating member 100, the moving assembly 200 and the telescopic member 300 is reduced, the service life of the rotating member is prolonged, the working reliability is ensured, and the paving efficiency is also improved.
The rotating member 100 may be a turntable, a wheel, or other rotatable element. The moving assembly 200 may be an electric sliding rail, a linear motor or other elements capable of driving the telescopic member 300 to move linearly, wherein when the moving assembly 200 is an electric sliding rail, a track of the electric sliding rail is a connecting portion 210, a slider of the electric sliding rail is a moving portion 220, the slider can reciprocate along the track, when the moving assembly 200 is a linear motor, a stator portion of the linear motor is a connecting portion 210, and a mover portion of the linear motor is a moving portion 220.

It should be noted that, at least one pickup member 400 is disposed at each telescopic end 320, which means that only one pickup member 400 may be fixedly disposed on each telescopic end 320, or two, three or more pickup members 400 may be fixedly disposed.
In addition, intermediate elements may be present between the pick 400 and the telescoping end 320 to facilitate installation and connection. As shown in fig. 1-4, in one embodiment, the segment laying mechanism 10 further includes an adapter 500 coupled to the telescoping end 320. The adapter 500 has an adapter surface 510 that can be matched to the outer contour of the segment. The pick-up member 400 is fastened to the adapting surface 510 by screwing, welding, riveting, or the like. In this way, after the adaptor 500 is fixed on the telescopic end 320 by welding, riveting or screwing, the pick-up member 400 is fixed on the adaptor surface 510 of the adaptor 500 by welding, riveting, screwing or clamping, and the mounting is convenient and reliable. Moreover, the profile of the adapting surface 510 is matched with the outer profile of the pipe piece, and after the pipe piece is picked up by the pickup piece 400, the outer side wall of the pipe piece is attached to the adapting surface 510, so that the pickup piece 400 is ensured to pick up the pipe piece stably and reliably, and falling is avoided. Moreover, at least two picking pieces 400 can be distributed on the adapting surface 510, so that the plane where the picking surfaces of all the picking pieces 400 are located is parallel to the adapting surface 510, and the at least two picking pieces 400 can be reliably and stably connected with the duct piece without gaps. The adaptor 500 may be an adaptor plate, or other structures.
As shown in fig. 3 and 4, the adapting surface 510 is further provided with a mounting groove 511. As shown in fig. 1 and 4, the pick-up 400 includes a suction nozzle 410 and a vacuum pump 420 for evacuating the suction nozzle 410. As shown in fig. 4, the suction nozzle 410 is disposed in the mounting groove 511, and the suction surface 411 and the transfer surface 510 of the suction nozzle 410 are on the same surface. In this way, when the telescopic end 320 of the telescopic piece 300 stretches out and draws back to drive the adapting surface 510 to move to be attached to the outer side wall of the pipe piece, the vacuum pump 420 can be utilized to vacuumize the suction nozzle 410, so that the pipe piece can be stably and reliably adsorbed and picked up, the pipe piece can be stably and reliably attached to the adapting surface 510, and the pipe piece can be transported to the position to be paved above by combining the retraction of the telescopic piece 300 and the movement of the moving part 220 along the second axial direction. The suction surface 411 of the suction nozzle 410 is an end surface of the suction nozzle 410 facing the duct piece, and preferably, the contour of the suction surface 411 is also matched with the outer contour of the duct piece, so that the bonding area is increased, and the suction is more firm. The vacuum pump 420 may be fastened to the rotating member 100 by fastening, screwing, riveting, or the like, or may be externally arranged. The mounting groove 511 may be a bar-shaped groove. Of course, in other embodiments, the picking member 400 may also pick up the tube sheets by clamping (e.g., grabbing by a robot arm) or the like.
The suction nozzle 410 may be fastened to the inner wall of the mounting groove 511 by a fastening, inserting or screwing method, or the suction nozzle 410 may be disposed in the mounting groove 511 by an intermediate element.
In one embodiment, the segment laying mechanism 10 further includes a mounting assembly (not shown). The mounting assembly is disposed within the mounting slot 511, and the mounting assembly enables the suction nozzle 410 to be mounted at any position along the length direction of the mounting slot 511 (as shown in the direction C of fig. 3 and 4).

The mounting assembly may be configured such that the suction nozzle 410 is mounted at any position along the longitudinal direction of the mounting groove 511, and may be realized by sliding fit between the mounting assembly and the suction nozzle 410, or by fixing the suction nozzle 410 in the longitudinal direction of the mounting assembly by welding, screwing, riveting, or the like.
As shown in fig. 3 and 4, in one embodiment, the mounting assembly includes a connector 610 and a mounting 620 disposed along the length of the mounting slot 511. The connector 610 is a sliding fit with the mount 620. Along the length direction of the mounting groove 511, the mounting member 620 is provided with at least two first coupling parts for fixedly coupling with the coupling member 610. The suction nozzle 410 is connected with the connection member 610. Thus, after the suction nozzle 410 is fixedly arranged on the connecting piece 610 in a screwing, riveting or welding mode, the suction nozzle 410 can be driven to flexibly move along the length direction of the mounting groove 511 through the sliding fit between the connecting piece 610 and the mounting piece 620, and the suction nozzle 410 is fixedly connected with different first connecting parts through the connecting piece 610, so that stable and reliable mounting and fixing can be realized after the mounting position of the suction nozzle 410 in the length direction of the mounting groove 511 is changed, and the reliability of work is ensured. By changing the installation position of the suction nozzle 410 in the length direction of the installation groove 511, the installation position of the suction nozzle 410 is adapted to the picking requirements of the duct pieces with different lengths and different weights, the stability and reliability of the duct piece picking are ensured, and the suction nozzle 410 can be attached to the outer side wall of the duct piece as much as possible, so that the suction effect is good. The mounting member 620 may be rod-shaped or bar-shaped, and the mounting member 620 may be connected to the inner wall of the mounting groove 511 by welding, riveting or screwing, so that the mounting member 620 is fixed in the mounting groove 511 along the length direction of the mounting groove 511, the connecting member 610 may be block-shaped or plate-shaped, and the connecting member 610 may be moved back and forth along the length direction of the mounting groove 511 by sliding the connecting member 610 and the sliding groove or sliding rail through a corresponding sliding groove or sliding rail formed in the mounting member 620, so as to drive the suction nozzle 410 to move back and forth along the length direction of the mounting groove 511.
Further, each mounting member 620 corresponds to at least two connecting members 610, and the connecting members 610 are disposed in one-to-one correspondence with the suction nozzles 410. Thus, at least two suction nozzles 410 can be arranged corresponding to one mounting piece 620 by utilizing at least two connecting pieces 610, stable and reliable adsorption pickup of the pipe pieces can be guaranteed, the mounting fixed position of each suction nozzle 410 in the mounting groove 511 can be flexibly adjusted, the pickup requirements of the pipe pieces with different sizes can be met, the adsorption force of the pipe pieces is guaranteed to be uniform, and the pipe pieces are prevented from falling after being suspended.
The fixed connection between the connecting piece 610 and the first connecting portion may be realized by plugging, clamping, screwing, and the like, which only needs to connect the connecting piece 610 and the mounting piece 620 into a whole stably and reliably.
