Description

Technical Field

[0001] The utility model relates to the technical field of pipe production, in particular to a steel skeleton plastic composite pipe rounding device. Background Art

[0002] Steel skeleton plastic composite pipe uses welded steel mesh skeleton as reinforcement layer, and both the inside and outside are high-density polyethylene plastic, which is an ideal pipe for conveying water and corrosive fluids. During the production process, due to the offset of the reinforced steel mesh skeleton or the poor symmetry of the compression cylinder of the pipe traction machine and the fluctuation of air pressure, the pipe ovality will be large, and this situation is inevitable and happens from time to time. When the ovality of the pipe exceeds the standard value, the pipe will not be able to be sealed and turned, and the ovality of the pipe needs to be corrected.

[0003] At present, the ovality correction of steel skeleton plastic composite pipe is offline correction, and the ovality is corrected by using steel inner support, but the existing roundness correction device has the following problems when used:

[0004] First, there is a measurement lag. When the correction data cannot be checked in time after the ovality of the pipe is calibrated, over-correction or repeated correction is prone to occur. Secondly, the existing correction tooling is inefficient and labor-intensive. The currently commonly used steel inner supports require manual operation throughout the process. In order to ensure that the inner supports have sufficient rigidity, the inner supports are heavy, and their practicality and operability are poor.

[0005] Therefore, the utility model proposes a steel skeleton plastic composite pipe rounding device. Utility Model Content

In order to ensure that the inner support has sufficient rigidity, the inner support is heavy, and its practicality and promotion are poor.

[0009] Furthermore, the correction structure includes a guide seat slidably sleeved with the guide rail, a hydraulic rod is fixedly connected to the inner side of the guide seat, an inner end of the hydraulic rod is fixedly connected to a mounting platform, and the mounting platform is also fixedly connected to the top center position of the base.

[0010] Furthermore, the correction structure also includes a support seat fixedly connected to the top of the guide seat, and the top of the support seat is fixedly connected to a matching fixed seat and a pressure platform.

[0011] Furthermore, the fixing seat and the supporting seat are both arranged in a semi-circular shape, and the pressure platform is arranged in an arc-shaped convex shape along the outer top surface of the fixing seat.

[0012] Furthermore, the outer limiting structure includes an outer limiting ring, a mounting groove on its surface, and an inner supporting platform, and the mounting groove and the inner supporting platform are respectively located at the outer side and the inner side of the outer limiting ring.

[0013] Furthermore, the connecting plate is embedded in the mounting groove at the same time.

[0014] Furthermore, a laser distance measuring mechanism is built into the outer limit ring, and a distance measuring head in the laser distance measuring mechanism is also embedded in the inner surface of the outer limit ring.

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] See also Figure 1-3 As shown, a steel skeleton plastic composite pipe rounding device includes a base 1, guide rails 2 are fixedly connected to both sides of the surface of the base 1, a correction structure 3 is sleeved on the guide rails 2, an outer limiting structure 4 is fixedly arranged on the outer side of the top of the correction structure 3, and the outer surface of the outer limiting structure 4 is fixedly connected to a matching connecting plate 14 and a support rod 13, and the bottom end of the support rod 13 is also fixedly connected to the base 1. When performing the correction operation, the external pipe is sleeved on the outer side of the pressure platform 10, and the external pipe is on the inner support platform 12 between the pressure platform 10 and the outer limiting ring 11. The outer limiting ring 11 limits the external pipe from the outer position to avoid excessive correction of the subsequent pipe. During the correction process, the laser ranging mechanism inside the outer limiting ring 11 detects the roundness of each position of the external pipe in real time, and cooperates with the correction structure 3 to complete the internal support correction operation. When using this device, it can effectively avoid excessive correction or repeated correction.

[0027] In the embodiment of the utility model, the correction structure 3 includes a guide seat 5 which is slidably connected to the guide rail 2, and a hydraulic rod 6 is fixedly connected to the inner side of the guide seat 5, and a mounting platform 7 is fixedly connected to the inner end of the hydraulic rod 6. The mounting platform 7 is also fixedly connected to the top center position of the base 1. The hydraulic rod 6 is used to push the guide seat 5 to slide horizontally along the guide rail 2, and the guide rail 2 and the guide seat 5 are used to facilitate the sliding adjustment of the entire correction structure 3 inside and outside.

[0028] The correction structure 3 also includes a support seat 8 fixedly connected to the top of the guide seat 5, and the top of the support seat 8 is fixedly connected to a matching fixed seat 9 and a pressure platform 10. The fixed seat 9 and the support seat 8 are both semi-annular, and the pressure platform 10 is convexly arranged along the outer top surface of the fixed seat 9. The semi-annular fixed seat 9 and the support seat 8 cooperate with the arc-shaped convex pressure platform 10 to achieve the effect of pressing and correcting the inner side of the external pipe.

[0029] When the external pipe is calibrated, the external pipe is placed on the calibration structure 3 so that the pipe is placed outside the pressure platform 10. Then the hydraulic rod 6 pushes the guide seat 5 to slide along the guide rail 2, and the sliding adjustment of the guide seat 5 drives the support seat 8, the fixed seat 9 and the pressure platform 10 to adjust inside and outside. Then the pressure platform 10 contacts the inner wall of the external pipe to perform the calibration internal support operation.

[0030] The outer limit structure 4 includes an outer limit ring 11 and a mounting groove 15 on its surface and an inner support platform 12. The mounting groove 15 and the inner support platform 12 are respectively located at the outer side and the inner side of the outer limit ring 11. The connecting plate 14 is also embedded in the mounting groove 15. The outer limit ring 11 is equipped with a laser ranging mechanism. The ranging head in the laser ranging mechanism is also embedded in the inner surface of the outer limit ring 11. The outer limit ring 11 is used to limit and protect the external pipe placed on the correction structure 3 from the outer position. At the same time, the internal laser ranging mechanism is used to measure the roundness of the placed external pipe. The inner support platform 12 is used to facilitate the support of the external pipe.
