Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic composite pipe production equipment, in particular to a sandblasting repair device for the pipe orifice of a steel-plastic composite pipe. Background Technique

[0002] The steel-plastic composite pipe has a plastic pipe inside the steel pipe and a steel pipe structure outside. This structure has many advantages. On the one hand, it has the functions of the plastic pipe and can be used to transport hot water or other liquids. The plastic has the characteristics of corrosion resistance and can also insulate heat. However, because the plastic pipe is very soft, in places with high strength requirements, simply using the plastic pipe cannot meet the requirements. Therefore, adding a steel pipe at the outer end of the plastic pipe can well solve these problems.

[0003] During the production process of the steel-plastic composite pipe, the outer wall of the steel pipe needs to be sandblasted. However, during the processing, production and transportation processes, the sandblasting on the outer walls at both ends of the steel pipe is often damaged. Nowadays, manual use of a brush is used to replenish the sand, which not only wastes labor, increases costs, but also has low work efficiency. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figure 1-2 shown, a steel-plastic composite pipe nozzle sandblasting repair device includes two symmetrically arranged workbenches 1. The workbenches 1 are arranged on both sides of the steel pipe conveying rack 2. The top of the workbench 1 is provided with a steel pipe roller rack 4 through a first cylinder 3. The steel pipe roller rack 4 includes a mounting rack 8. The bottom of the mounting rack 8 is connected to the telescopic end of the first cylinder 3. The first cylinder 3 is fixed on the workbench 1. Two misaligned first rubber rollers 9 and second rubber rollers 10 are mounted on the mounting rack 8 through bearing seats. The first rubber roller 9 is driven by a motor 11 mounted on the bearing seat.

[0018] On one side of the steel pipe roller rack 4 close to the steel pipe conveyor rack 2, there is a steel pipe blocking assembly, which includes a blocking plate 12 and a second cylinder 13. The second cylinder 13 is fixed on the workbench 1, and the telescopic end of the second cylinder 13 is vertically upward and connected to the bottom of the blocking plate 12. A buffer rubber pad is provided on one side surface of the blocking plate 12.

[0019] On the other side of the steel pipe conveyor rack 2, there is a spraying assembly, which includes a transverse moving plate 5 connected to the workbench 1 through an adjusting assembly. The adjusting assembly includes a slide rail 14 laid on the workbench 1 and a third cylinder 15 fixed on the workbench 1. A chute is opened on the bottom surface of the transverse moving plate 5, and the transverse moving plate 5 is slidably connected to the slide rail 14 through the chute. The telescopic end of the third cylinder 15 is connected to the transverse moving plate 5.

[0020] The top of the transverse moving plate 5 is connected with an L-shaped connecting plate 6, and a spray gun 7 is installed on the L-shaped connecting plate 6. The spray gun 7 is connected to the raw material tank through a pump.

[0021] The operation process of the present utility model is as follows:

[0022] During use, when the composite pipe rolls on the steel pipe conveyor rack 2 and is blocked by the blocking plate 12, then the first cylinder 3 controls the steel pipe roller rack 4 to rise, so that the first rubber roller 9 and the second rubber roller 10 support the two ends of the composite pipe. Then the motor 11 is started, and the composite pipe is driven to rotate by the first rubber roller 9. Then the telescopic end of the third cylinder 15 extends, so that the spray gun 7 is placed above the end of the steel pipe. Then the spray gun 7 starts sandblasting to repair the end of the composite pipe. After the repair is completed, the third cylinder 15 resets, the motor 11 stops working, and then the first cylinder 3 resets, so that the composite pipe falls on the steel pipe conveyor rack 2. Then the telescopic end of the second cylinder 13 retracts, so that the blocking plate 12 descends and can no longer block the composite pipe, and the composite pipe rolls on the steel pipe conveyor rack 2.

[0023] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
