Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, and in particular to a gas pipeline anti-corrosion coating construction equipment. Background Technology

[0002] Gas pipelines, as the name suggests, are pipes used to transmit combustible gases. They typically use metal gas pipes instead of traditional rubber hoses, offering advantages such as flexibility without deformation, corrosion resistance, and long service life. Before use, gas pipelines require anti-corrosion measures, including coating, epoxy powder coating, insulating tape wrapping, and epoxy resin coating. Each of these measures has its advantages and disadvantages and is suitable for different environments. Anti-corrosion coatings are applied to the pipe surface to form a protective layer, preventing external erosion and damage. Common anti-corrosion coating materials include asphalt coatings, epoxy coatings, and polyethylene coatings, which offer advantages such as acid and alkali resistance, wear resistance, and lightweight properties. Current pipeline anti-corrosion methods often rely on manual spraying with handheld spray guns, which is time-consuming and labor-intensive, and uneven spraying of the inner pipe can affect the normal use of the pipeline.

[0003] Chinese patent CN221268667U discloses a high-efficiency spraying device for anti-corrosion coating of pipelines. This patent fixes the pipeline body by setting a moving component and drives the threaded rod to rotate by setting a servo motor, thereby realizing the horizontal movement of the moving component and pipeline by the moving plate, so that the spraying component can be inserted into the inner cavity of the pipeline for uniform spraying, which saves time and effort and provides uniform and efficient spraying.

[0004] However, the aforementioned patent only applies uniform spraying to the inner wall of the pipe, and cannot simultaneously spray both the inner and outer walls of the pipe. Additional equipment is required to spray the outer wall of the pipe, resulting in low efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a gas pipeline anti-corrosion coating construction equipment, which solves the problem that when there is a lot of dust, the existing technology cannot be automatically cleaned, so the collection bag needs to be disassembled and manually cleaned, resulting in a short service life, time-consuming and labor-intensive cleaning, and reduced practicality of the device.

[0006] To achieve the above objectives, this utility model provides a gas pipeline anti-corrosion coating construction equipment, including a box body. A fixing plate is fixedly connected to the bottom right side of the inner cavity of the box body. A three-way valve is inserted into the right side wall of the fixing plate. A fixing component is fixedly connected to the bottom of the inner cavity of the box body. A screw is rotatably connected to the inner cavity of the fixing component. A connecting component is screwed to the outer side wall of the screw. Vertical plates are fixedly connected to the front and rear sides of the top of the connecting component.

[0007] It also includes a pushing mechanism and a spraying mechanism;

[0008] The pushing mechanism includes a cylinder, a connecting plate, a support member, a connecting shaft, a guide roller, a transmission member, a second motor, and a belt. The cylinder is fixedly connected to the inner middle of the vertical plate, the connecting plate is fixedly connected to the output end of the cylinder, the support member is fixedly connected to the bottom of the connecting plate, the connecting shaft is rotatably connected to the top of the support member, the guide roller is fixedly connected to the top of the connecting shaft, the transmission member is fixedly connected to the middle of the top of the front guide roller, the second motor is embedded in the top of the front connecting plate, and the belt is sleeved between the output wheel of the second motor and the connecting groove of the transmission member.

[0009] The spraying mechanism includes a cylinder, a connecting block, and a first spray head. The cylinder is fixedly connected to the left end of the connecting block, and the connecting block is fixedly connected to the upper and lower sides of the left side wall of the fixed plate. The first spray head is inserted into the left side of the inner side wall of the cylinder.

[0010] The top center of the box is fitted with a hopper, the bottom of the hopper is connected to a storage box, the right side wall of the storage box is fixedly connected to a pump body, and the output end of the pump body is connected to a pipe.

[0011] The bottom end of the pipe is connected to the input flange of the three-way valve, and a feed port is opened in the middle of the lower left side wall of the box.

[0012] The left end of the screw passes through the left side wall of the inner cavity of the fixing member and is rotatably connected to the lower side of the left side wall of the inner cavity of the housing. The right end of the screw passes through the right side wall of the inner cavity of the fixing member and extends to its outer side. A first motor is fixedly connected to the lower side of the right side wall of the inner cavity of the housing, and the output end of the first motor is fixedly connected to the right end of the screw through a coupling.

[0013] The three-way valve has a connecting pipe at one end of its output port, a second nozzle at the left end of the connecting pipe, and the other end of its output port is connected to the cylinder.

[0014] This utility model discloses a gas pipeline anti-corrosion coating construction equipment. A pushing mechanism, including a cylinder, connecting plate, support, connecting shaft, guide roller, transmission component, second motor, and belt, is installed on the connector. The cylinder drives the guide roller to clamp the gas pipeline inward, and the second motor drives one side of the guide roller to rotate, while the other side guide roller follows, pushing the gas pipeline into the cylinder. A spraying mechanism, including a cylinder, connecting block, and first nozzle, is installed outside the second nozzle. When the gas pipeline is inserted outside the second nozzle, the second nozzle sprays the inside of the pipeline, while the first nozzle on the cylinder simultaneously sprays the outside of the pipeline. This allows for simultaneous spraying of the inner and outer walls of the gas pipeline, resulting in high efficiency. Attached Figure Description
