Description

Duct piece bracket for spraying concrete duct piece Technical Field The utility model belongs to the technical field of duct piece production and processing, and particularly relates to a duct piece bracket for spraying concrete duct pieces. Background With the acceleration of the urban process, the tunnels such as urban subways, water conservancy and hydropower, highways, railways and the like all need duct pieces for supporting, the shield duct pieces are main assembly members for shield construction, are the innermost barrier of the tunnels, bear the functions of resisting soil layer pressure, groundwater pressure and some special loads, and are an indispensable step for spraying curing agents for the duct pieces after demolding in the production process, so that the duct pieces need to be turned over by 90 degrees. The segment is generally buckled on a support plate which is horizontally arranged, the support plate is driven by a power cylinder to turn from horizontal to vertical, and the segment turns from a horizontal state to a vertical state. The prior patent with publication number CN218177244U carries out technical innovation aiming at the condition that the pipe piece is easy to displace when being overturned in the supporting plate, a limiting piece is added, the shield pipe piece is limited and clamped, but the weight of a single piece of the shield pipe piece is huge and is basically 3 tons or more, the limiting piece is arranged at the bottom of the pipe piece, and if the displacement condition occurs, the limiting piece is easy to be damaged by the dumped shield pipe piece, therefore, the pipe piece bracket for spraying the concrete pipe piece is provided. Disclosure of utility model In view of the above, the utility model aims to provide a duct piece bracket for spraying concrete duct pieces, which solves the problem that shield duct pieces are easy to shift and fall when turning over. The utility model solves the technical problems by the following technical means: The utility model provides a section of jurisdiction bracket is used in concrete pipe piece spraying, including base and section of jurisdiction, fixed mounting has supporting shoe and support on the base, it has the roll-over stand to articulate on the support, the roll-over stand level is placed on the supporting shoe, it has the pneumatic cylinder to articulate on the base, the pneumatic cylinder output is articulated with the roll-over stand, the top both sides of roll-over stand under vertical state articulate there is the stopper, there is the telescopic link through the universal joint between stopper and the base, the hinge point between roll-over stand under vertical state and the stopper is greater than the maximum length of telescopic link to the hinge point between telescopic link and the base, the stopper tip rotates and is equipped with the rubber gyro wheel, the rubber gyro wheel contacts with the section of jurisdiction surface when the roll-over stand reaches vertical state. On the basis of the technical scheme, the utility model also carries out the following improvement: Furthermore, the overturning frame is detachably provided with a plurality of top plates, the upper surface of each top plate is arc-shaped and is matched with the radian of the inner surface of the duct piece, the top plates can be prevented from sliding off the overturning frame when the duct piece is placed on the overturning frame by the lifting appliance, and the top plates can be detached so as to be convenient to replace and adjust according to the size of the duct piece. Furthermore, the flexible pad is arranged on the inner surface of the bottom of the vertically placed top plate surface and the vertically placed turnover frame, so that the friction force between the pipe piece and the top plate can be increased in the turnover process, the sliding speed of the pipe piece on the turnover frame in the turnover process is slowed down, the impact force on the turnover frame in the turnover process is reduced, and meanwhile, the flexible pad is arranged on the top plate surface to prevent the pipe piece from being scratched by the edge of the top plate when the pipe piece is lifted after the pipe piece is turned over. Furthermore, the anti-slip pad is arranged at the bottom of the base, so that the friction force between the device and the ground can be increased, and the problem that the whole device is overturned due to overlarge segment mass in the overturning process is avoided. Further, the telescopic rod comprises an outer rod and an inner rod, a through groove is formed in the side face of the outer rod, a sliding block is fixedly arranged at the bottom of the inner rod and penetrates out of the through groove, a screw is rotatably arranged on the side wall of the top of the outer rod through threads of the through groove, the length of the adjusting screw penetrating the through groove is used for limiting the maximum distance tha
