As shown in fig. 6, fig. 6 is a schematic structural diagram of the deviation rectifying mechanism 6.
Considering that the influence of lateral left-right deviation can be caused by the influence of factors such as vibration and slope in the transportation process of the duct piece, the deviation correcting mechanism 6 is additionally arranged in the embodiment. Specifically, the deviation rectifying mechanism 6 mainly includes a deviation rectifying seat 61, a deviation rectifying cylinder 62 and a deviation rectifying wheel 63. Wherein, the deviation rectifying seat 61 is arranged at the top of the trolley frame 11, and is provided with two seats at the same time, and is respectively positioned at two sides of the conveying frame 2. The deviation rectifying cylinders 62 are disposed on the deviation rectifying bases 61, and generally, a plurality of groups of deviation rectifying cylinders 62 are disposed at the same time, two deviation rectifying cylinders 62 corresponding to the left and right sides are a group, for example, 2-3 groups, and the deviation rectifying cylinders on the left and right sides of any group can perform synchronous telescopic motion, and any group of deviation rectifying cylinders can be controlled to work independently or can be telescopic in cooperation. The rectification wheels 63 are arranged at the tail ends of the piston rods of the rectification cylinders 62, can rotate, and are mainly used for rolling and abutting against the side faces of the corresponding sides of the segments. So set up, when the section of jurisdiction was transported to when mechanism 6 through rectifying, the distance was predetermine in each cylinder 62 extension of rectifying for the side of the wheel face of rectifying wheel 63 and the left and right sides of section of jurisdiction forms the roll butt, utilizes this butt effort with the section of jurisdiction in horizontal ascending position centering location, prevents that the section of jurisdiction from producing lateral shifting.
Generally, the deviation correcting mechanism 6 is integrally arranged at the front end of the conveying frame 2, and the pipe piece is centered and positioned by the deviation correcting mechanism 6 and then is conveyed to the temporary storage frame 5.
As shown in fig. 7, fig. 7 is a schematic structural diagram of centering and positioning the tube sheet by the deviation rectifying mechanism 6.
Considering that the section of jurisdiction is the arc piece, when it was placed on transport mechanism 3, the centre of a circle down, and both sides also slope down, for conveniently forming the butt, in this embodiment, the top surface of rectifying a deviation seat 61 specifically is the inclined plane, and the slope is up, and rectifying a deviation cylinder 62 specifically sets up on this inclined plane to make rectifying a deviation cylinder 62 orientation keep for the slope up, with corresponding with the side of section of jurisdiction. The specific elevation angle of the deviation-correcting cylinder 62 is determined according to the shape of the segment.
As shown in fig. 8, fig. 8 is a schematic structural diagram of the temporary storage rack 5.

Spacing seat 53 sets up the position at the front end of section of jurisdiction layer board 52, and the position of the front end terminal surface of mainly used restriction section of jurisdiction prevents that the section of jurisdiction from being transported too far.
In addition, when preventing that present section of jurisdiction from not being got by segment erector clamp, next section of jurisdiction transports again to the frame of keeping in 5 on, this embodiment is provided with limit switch 7 on spacing seat 53. Specifically, the limit switch 7 is mainly used for detecting the limit condition of the duct piece on the limit seat 53, and when the duct piece is still detected, the limit switch 7 suspends the operation of the driving mechanism 4 to prevent the two duct pieces from colliding; when detecting that the duct piece is clamped, the limit switch 7 sends an issuing instruction to the driving mechanism 4, and the operation can be continued.
Further, in the present embodiment, a step switch 8 is further added, the step switch 8 is usually disposed in the rear end region of the conveying frame 2, and both the limit switch 7 and the step switch 8 are in signal connection with the control end of the driving motor 41 to respectively control the on-off state of the driving motor 41. The priority of the stop control of the driving motor 41 by the limit switch 7 is higher than the priority of the start control of the driving motor 41 by the step switch 8, that is, when the stop control of the driving motor 41 by the limit switch 7 is not released, the start control of the driving motor 41 by the step switch 8 cannot be realized, so that the misoperation can be conveniently caused.
