Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of PCCP pipe processing, and in particular relates to a PCCP pipe fine wire winding machine. Background Art
[0002] During the production process of the pipeline, in order to enhance the pressure resistance and strength of the pipeline, a wire mesh will be wound on the surface of the pipeline, which can further improve the comprehensive performance of the pipeline. PCCP is the abbreviation of prestressed steel cylinder concrete pipe, which refers to a water pipe made by winding annular prestressed steel wire on a high-strength concrete pipe core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is mainly used in large-scale water conservancy transportation projects. Its production process includes: steel cylinder production, concrete pipe core molding, winding annular prestressed steel wire on the pipe core and making a cement mortar protective layer outside the steel wire. However, in the actual production process, winding annular prestressed steel wire on the pipe core is a key process, and the control of the wire winding quality is the top priority related to the life of the pipe, especially for small-diameter PCCP pipes. During the wire winding process, the rotation of the rotating grab disk of the wire winding machine drives the PCCP pipe core to rotate, and the outer surface of the pipe core is wound with high-strength steel wire with a certain stress.
[0003] In the prior art, when the PCCP pipe is wire-wrapped, the stress fluctuation of the high-strength steel wire wrapped around the pipe core increases. The different tightness of the steel wire winding will cause uneven stress values of the steel wire wrapped around the pipe core, leaving hidden dangers to the internal quality of the pipe.
[0004] Therefore, a PCCP pipe fine wire winding machine is needed to solve the problem of poor wire winding effect when the wire winding is performed on the outside of the PCCP pipe in the prior art. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PCCP pipe fine wire winding machine, comprising a wire winding frame, a connecting seat, a hydraulic cylinder, and a grabbing plate, wherein a side wall of one side of the wire winding frame is fixed with a placing platform, a top side wall of the placing platform is rotatably connected with a rotating seat, the hanging plate is installed on one side side wall of the placing platform, the top of the connecting seat is rotatably installed on the top of the placing platform, a mounting groove is opened inside the connecting seat, one end of the hydraulic cylinder is installed inside the connecting seat, the output end of the hydraulic cylinder is fixed to an outer wall of one side of the grabbing plate, a driving motor is fixed to the bottom side wall of the rotating seat, a lifting frame is fixed to one side wall of the wire winding frame, a sliding rail is installed inside the lifting frame, a mounting seat is slidably connected inside the sliding rail, a wire feeding wheel is installed inside the mounting seat, an automatic CNC is installed on one side side wall of the sliding rail, a CNC line is installed between one end of the CNC and the bottom of the mounting seat, and a moving component matching the wire winding wheel is installed on one side of the wire winding frame.
[0007] It should be noted in the scheme that the moving component includes a guide circular rail fixed to one side wall of the mounting seat, a guide seat is fixed to one side wall of the mounting seat, a telescopic column is fixed to one side wall of the guide seat, a mounting groove is provided inside the telescopic column, a telescopic spring is fixed to one side wall of the telescopic column, a moving plate is fixed to one end of the telescopic spring, and one side wall of the moving plate is rotatably connected to a rotating wheel.
[0008] It is further worth noting that one end face of the guide circular rail is arranged as an arc surface, and one end face of the guide circular rail is flush with the top end face of the wire feeding wheel.
[0009] It should be further explained that a limit seat is installed on one side outer wall of the mounting seat, an arc-shaped limit ring is fixed on one side outer wall of the limit seat, and the height of the arc-shaped limit ring is higher than the height of the plane where the guide circular rail is located.
[0010] As a preferred embodiment, the outer surface of one end of the grabbing plate is in an arc shape, and the grabbing plate is located above the rotating seat and is distributed in a circle.
[0011] As a preferred embodiment, four symmetrically arranged guide wheels are fixed to the bottom of the rotating seat, and the guide wheels are slidably connected to an outer wall of one side of the placement table.
[0012] Compared with the prior art, the PCCP pipe fine wire winding machine provided by the utility model has at least the following beneficial effects:
[0013] () The steel wire raw material is moved by the wire feeding wheel to perform wire winding operation on the outside of the PCCP pipe. At the same time, the driving motor drives the PCCP pipe to rotate through the rotating seat, so that the steel wire is wound around the outside of the PCCP pipe. Under the action of the grabbing disc, the inner side of the PCCP pipe is contacted and limited, thereby improving the stability of the PCCP pipe during rotation and wire winding.
[0014] () Through the setting of telescopic spring and rotating wheel, the wire winding is limited when the PCCP pipe is wound, so that the wire winding is closer to the outside of the PCCP pipe, so that the PCCP pipe can be wound more evenly during the wire winding. Under the action of the guide circular rail, the steel wire is easier to slide during the wire winding, which improves the convenience of moving the wire winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1-4 The utility model provides a PCCP pipe fine wire winding machine, including a wire winding frame 1, a connecting seat 2, a hydraulic cylinder 3, and a grabbing plate 4. A placing table 5 is fixed to one side wall of the wire winding frame 1, and a rotating seat 6 is rotatably connected to the top side wall of the placing table 5. The hanging plate is installed on one side side wall of the placing table 5, and the top of the connecting seat 2 is rotatably installed on the top of the placing table 5.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the moving component 12 includes a guide circular rail 120 fixed to one side wall of the mounting seat 10, a guide seat 121 is fixed to one side wall of the mounting seat 10, a telescopic column 122 is fixed to one side wall of the guide seat 121, a mounting groove is provided inside the telescopic column 122, a telescopic spring 123 is fixed to one side wall of the telescopic column 122, a moving plate 124 is fixed to one end of the telescopic spring 123, and a rotating wheel 125 is rotatably connected to one side wall of the moving plate 124.
