[0002] Sandblasting is a common surface treatment process, especially for some pipe parts. Most existing pipe sandblasting machines have only one spray chamber. In order to ensure that the outer surface of the pipe is treated, the pipe and the spray gun need to maintain relative rotation.

[0003] For example, the Chinese invention patent publication number CN110936301B discloses a sandblasting device for metal pipes, including a sandblasting mechanism, a conveying mechanism for conveying the metal pipes to enter and exit the sandblasting mechanism; the conveying mechanism includes a frame, a screw rod rotatable around its own axis and arranged on the frame, a first driving motor for driving the screw rod to rotate, a nut connector sleeved on the screw rod, a claw assembly rotatable around its own axis and arranged on the nut connector for clamping the metal pipe, and a first driving motor for driving the claw assembly to rotate. a second driving motor for driving; a sleeve for sleeve-mounting a metal pipe is pluggable in the claw assembly, a gap is provided in the sleeve along its axial direction, and the gap is used to disconnect the sleeve along the radial direction of the sleeve; a sandblasting mechanism comprises a shell with a hollow inner cavity, a first through hole for allowing the metal pipe to enter, a conveying roller arranged in the shell for cooperating in conveying the metal pipe, and a sandblaster arranged in the shell for sandblasting toward the metal pipe, the sandblaster is fixed in the shell and is used to spray polishing sand toward one side of the metal pipe.

[0004] In this scheme, the pipe is conveyed axially by a conveying mechanism and driven to rotate around the axis at the same time, thereby achieving uniform circumferential sandblasting of the pipe.

For this reason, the applicant wants to change the processing method, simplify the conveying structure, abandon the rotation function, and only retain the conveying function. Such a processing method is bound to require improvements to the existing sandblaster, so a sandblasting device that can achieve circumferential sandblasting is designed. Utility Model Content

A plurality of spray guns 2 are provided and are evenly distributed on the gun disc 1 along the circumferential direction, so as to realize uniform sandblasting of the outer peripheral surface of the pipe that makes a linear motion along the axial direction. Each spray gun 2 is radially adjustable and installed on the gun disc 1, so that different sandblasting coverage areas can be achieved to meet the sandblasting requirements of pipes of different diameters. For pipes of different diameters, the optimal sandblasting scheme can be achieved by adjusting the radial distance of the spray guns 2 and the number of the spray guns 2, which is more flexible to use.

[0035] Specifically, the gun disc 1 is evenly distributed with the same number of strip grooves 1-1 as the spray guns 2 along the circumferential direction. The two sides of each strip groove 1-1 are symmetrically and parallelly provided with pads 3 fixedly installed on the gun disc 1, so as to form a slide groove. Each slide groove is provided with a matching slider 4. The spray gun 2 is fixedly installed on the slider 4. The radial movement of the spray gun 2 is achieved by sliding the slider 4. A pressing plate 5 tightly pressed on the slider 4 is detachably fixed on each pad 3 by screws, so as to achieve the fixation of the spray gun 2. The overall structure is simple and easy to adjust. In order to maximize the radial adjustment range, the two ends of the strip groove 1-1 extend to the inner ring and outer ring of the gun disc 1 respectively, so as to meet the sandblasting processing requirements of pipes with more diameters.

When multiple devices are arranged side by side, the circumferential staggered distribution can be achieved, further improving the sandblasting effect of the outer peripheral surface. The width of the gun rack mounting plate 6 is smaller than the diameter of the gun disc 1. By designing the size difference between the width of the gun rack mounting plate 6 and the diameter of the gun disc 1, it is convenient for the debugging personnel to hold the gun disc 1 when rotating and adjusting the gun disc 1.

[0037] Two support rods 7 are arranged opposite to each other on the rear side of the gun mount plate 6. The support rods 7 are C-shaped channel steels, which can reduce the material consumption and save costs while ensuring the structural strength. A mounting slot frame 8 is provided between the support rod 7 and the gun mount plate 6. A plurality of strip grooves 8-1 are arranged on both sides of the mounting slot frame 8 along its length direction. A second through hole is provided in the center of the area overlapping the strip groove 8-1 on the support rod 7. A locking bolt penetrating the strip groove 8-1 is provided in the second through hole, so that the gun mount plate 6 can be connected to the support rod 7 in an adjustable height direction through the mounting slot frame 8. By providing the support rod 7, it is convenient to set up and install the gun tray 1, and the height can be adjusted to meet the sandblasting requirements of more heights. A connecting plate 9 is fixedly welded on the top of the support rod 7, and a waist-shaped groove 9-1 is provided on the connecting plate 9 to facilitate the hoisting operation.

[0038] In this embodiment, a ring-shaped gun disc 1 is provided, the inner ring of which provides a path space for the transmission of the pipe, and a plurality of spray guns 2 are evenly distributed along its circumference, so that when the pipe is transmitted along the axial direction through the inner ring of the gun disc 1, the entire outer circumference can be covered by the sandblasting range, and uniform circumferential sandblasting can be achieved without a complex rotating mechanism, with a simple structure and low manufacturing cost.
