Description

Technical Field

[0001] The utility model relates to the technical field of pipeline grinding equipment, in particular to a grinding equipment for production and processing of special pressure pipelines. Background Art

[0002] Pressure pipe is a pressure steel pipe or hydraulic steel pipe, which is a steel pipe used to transport water with great water pressure. The inside of the steel pipe is a closed environment, and the strength of the water flow can be controlled by switching the sluice gate or fence. In order to ensure the production quality during the production process of the pressure pipe, the outer and inner walls of the pressure pipe need to be polished, which requires the use of polishing equipment. After searching, the prior art (application number: CN202322050356.3) records "a grinding device for pressure pipe production and processing, including a base frame, a lifting frame is fixedly installed on the base frame, a lifting seat is slidably connected in the lifting frame, a rotating seat is rotatably connected in the lifting seat, a first mounting frame is fixedly installed on the left side of the rotating seat, a second mounting frame is fixedly installed on the left side of the first mounting frame, a first threaded rod is rotatably connected in the first mounting frame, two sliders are sleeved on the first threaded rod, a second connecting rod is fixedly installed on the left side of the two sliders, and an outer grinding ring is fixedly installed on the left side of the two second connecting rods. The grinding device for pressure pipe production and processing can be adjusted according to the needs of use, which is convenient for grinding pressure pipes with different diameters and wall thicknesses, thereby further improving the applicability of the device, and at the same time, the outer wall and inner wall of the pressure pipe can be ground at one time, reducing the operation steps of the grinding process, which not only improves the production efficiency of the pressure pipe, but also saves the equipment purchase cost."

The metal dust accumulated in the pipe will hinder the contact between the grinding block and the inner wall of the pipe, resulting in the grinding effect being affected during the grinding process; secondly, the existing pipe grinding equipment can generally only grind one pipe at a time, resulting in deviation in the grinding efficiency.

[0022] In this embodiment, the base 1, the vertical plate 2, the outer grinding member 3, the inner grinding member 4 and the driving assembly 5 constitute the main structure of the grinding equipment for the production and processing of special pressure pipes involved in this application.

[0023] In this embodiment, the electric push rod 412 controls the ejection stroke of the piston rod through an external controller, so that when the inner wall of the pressure pipe is polished, the inner polishing plate 41 contacts the inner wall of the pipe but does not move in conjunction with it, and when the outer wall of the pressure pipe is polished, the inner polishing plate 41 maintains an internal support and clamping linkage effect with the pipe.

[0024] It should be noted that when the grinding equipment involved in the present application is in operation, the other end of the special pressure pipe is assisted by manual or robotic clamping.

[0025] In this embodiment, both the inner polishing layer 411 and the outer polishing layer 311 are configured as arc-shaped structures, so as to facilitate the contact with the inner and outer walls of the pipe.
