Description

Technical Field

[0001] This utility model relates to the field of tube processing, and in particular to an adjustable rotary table structure. Background Technology

[0002] Currently, the processing of pipe bodies (such as reinforced concrete cement pipe (RCP) or prestressed concrete cylinder pipe (PCCP)) involves wire winding machines produced by vertical wire winding or shotcrete machines produced by shotcrete processes.

[0003] To apply a protective layer of prestressed steel wire or sprayed mortar to the outer wall of RCP or PCCP pipe cores, such as Figure 2 As shown, a rotary worktable is required to place the core tube and rotate under the drive of a motor, coupling, reducer, and gears, as in the patent application number 202120580955.4 filed by the applicant, entitled "Main Rotary Mechanism of Wire Winding Machine".

[0004] To achieve this goal, guide wheels need to be installed on the rotary table. The functions of the guide wheels are: first, to guide the tube during hoisting; and second, to generate friction with the inner wall of the tube after it is placed on the rotary table, thus driving the tube to rotate.

[0005] Because different tube cores have different inner diameters, the guide wheel needs to be manually adjusted according to the different tube cores after changing the tube core specifications. After being adjusted to the appropriate position, it is then tightened with bolts. This process is time-consuming and labor-intensive, requiring not only the cooperation of a crane but also workers to remove and tighten bolts, resulting in high labor intensity and low efficiency.

[0008] Its characteristic is that it further includes a plurality of sliders, which are evenly distributed in a ring on the rotary table. Each slider is provided with a guide wheel and is slidably connected to the rotary table.

[0009] It also includes a cone, which is movably connected to the center of the rotary table;

[0010] The cone engages with the inner sides of several sliders via inclined surfaces.

[0011] The bottom of the rotary disc is provided with a lifting mechanism in the middle, the lifting mechanism is used for connecting a cone through the rotary disc,

[0012] The lifting mechanism is a pneumatic cylinder or an electric push rod.

[0013] The hydraulic cylinder is further connected in the middle of the bottom of the rotary disc, and the push rod of the hydraulic cylinder is connected to the cone through the rotary disc.

[0014] The hydraulic station is further provided with a rotary joint on the hydraulic cylinder, and the rotary joint is connected to the hydraulic station through a pipeline.

[0015] The sliding block is L-shaped, the guide wheel is arranged on the top of the horizontal section of the sliding block, and the horizontal section of the sliding block is provided with a placement area outside the guide wheel.

[0016] In the working process of the utility model, the guide wheel and the sliding block are made into an integrated structure, and cooperate with the slide on the rotary disc, the sliding block can slide along the diameter direction, and the operation is convenient.

[0017] When different production specifications are replaced, the position of the sliding block on the rotary disc is adjusted, and when the sliding block is moved, the displacement is generated through the up and down movement of the hydraulic cylinder, so that the sliding block reaches the required position. Thus, the purpose of automatically adjusting the guide wheel on the rotary disc according to the die core specification is achieved, and the adaptability is improved.
