Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to a line sandblasting device.

[0002] Background technology.

[0003] Line sandblasting equipment is a specialized maintenance tool widely used in power, telecommunications, rail transit, and pipeline engineering fields. It is primarily used for surface treatment of various line components. It uses compressed air to drive abrasive particles into a high-speed jet, which acts on the surface of components such as transmission towers, communication poles, rails, and oil and gas pipelines. This achieves functions such as rust removal, scale removal, removal of old coatings, and surface roughening, providing a suitable substrate for subsequent anti-corrosion coating, welding, and other processes.

[0004] In the long-term use of traditional line sandblasting equipment, clogging of the nozzles and connecting pipes has become a major bottleneck restricting its efficient operation. Since line maintenance is mostly carried out outdoors, impurities easily mix into the abrasive, and rust fragments and old paint from the surface of line components can enter the nozzle from the reverse. Combined with factors such as damp abrasive clumping and eddy currents created by irregularly shaped nozzle channels, clogging is highly likely. Traditional methods require manual shutdown and nozzle disassembly for unclogging using wire cutters or high-pressure air blowers, which is cumbersome.

[0005] Therefore, this application provides a line sandblasting device. Utility Model Content

[0006] This utility model provides a line sandblasting device, which can solve the problem that traditional line sandblasting devices require manual shutdown and nozzle disassembly after long-term use, and unblocking by means of wire poking, high-pressure air blowing, etc., which is quite troublesome to use.

[0007] This utility model provides a line sandblasting device, including:

[0008] The sandblasting mechanism includes a power mechanism and a material mechanism. The power mechanism also includes an air tank, on which an air compressor is fixedly mounted. The output end of the air compressor is fixedly connected to the input end of the air tank. The material mechanism also includes a movable base, on which an abrasive tank and a water tank are fixedly mounted. The output end of the air tank is connected to both the abrasive tank and the water tank via hoses. Solenoid valves are installed at the connections between the air tank, the abrasive tank, the water tank, and the hoses.

[0009] The spray gun mechanism includes a gun body connected to the output end of the abrasive tank via a hose. A pressure gauge is integrally installed on one side of the gun body, and a flushing pipe is integrally installed at the lower end of the gun body. The input end of the flushing pipe is fixedly connected to one side of the clean water tank via a hose, and a ball valve is fixedly installed on the outer wall of one side of the gun body.

[0010] In a line sandblasting device according to an embodiment of the present invention, a collar is rotatably connected to the outer wall of the gun body near its nozzle. A connecting rod one is fixedly installed on one side of the collar. A slider is slidably connected to the outer wall of the connecting rod one. A connecting rod two is fixedly installed on one side of the slider. A rotating shaft is rotatably connected to one side of the connecting rod two. A nozzle is fixedly installed at the lower end of the rotating shaft. One side of the nozzle is connected to the nozzle of the gun body through a hose.

[0011] In the line sandblasting device of this utility model, a plurality of positioning holes are evenly arranged around the rotating shaft on one side of the upper wall of the second connecting rod.

[0016] The technical solution provided in this application embodiment may include the following beneficial effects: This application designs a line sandblasting device. After the sandblasting device has been used for a long time, the air pressure inside the gun body is monitored by a pressure gauge. When a blockage occurs, the pressure gauge detects a sudden increase in pressure.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Example 1

[0028] like Figures 1 to 2 As shown, this application provides a line sandblasting device, including:

[0029] The sandblasting mechanism 100 includes a power mechanism 10 and a material mechanism 20. The power mechanism 10 also includes an air tank 11. An air compressor 12 is fixedly installed on the upper surface of the air tank 11. The output end of the air compressor 12 is fixedly connected to the input end of the air tank 11. The material mechanism 20 also includes a movable base 21. An abrasive tank 22 and a clean water tank 23 are fixedly installed on the upper surface of the movable base 21. The output end of the air tank 11 is connected to the abrasive tank 22 and the clean water tank 23 through a hose. The spray gun mechanism 30 includes a gun body 31 connected to the output end of the abrasive tank 22 through a hose. A pressure gauge 32 is integrally installed on one side of the gun body 31. A flushing pipe 33 is integrally installed at the lower end of the gun body 31. The input end of the flushing pipe 33 is fixedly connected to one side of the clean water tank 23 through a hose. A ball valve 34 is fixedly installed on the outer wall of one side of the gun body 31. Solenoid valves are installed at the connection points between the air tank 11, the abrasive tank 22, and the clean water tank 23 and the hose.

[0030] After adopting the above technical solution, when using the sandblasting device, the air compressor 12 generates high-pressure air and stores it inside the air tank 11. The high-pressure air enters the abrasive tank 22 through the air tank 11. When the ball valve 34 is opened, the high-pressure air sends the abrasive and water in the abrasive tank 22 into the gun body 31 and sprays it onto the surface of the circuit component to be treated through the gun body 31. After the sandblasting device has been used for a long time, the air pressure inside the gun body 31 is monitored by the pressure gauge 32. When a blockage occurs, the pressure gauge 32 detects a sudden increase in pressure. At this time, by closing the ball valve 34, clean water in the clean water tank 23 is sent into the gun body 31 through the flushing pipe 33. The clean water washes away the abrasive adhering to the gun body 31 and clears the blockage of the spray gun. It is not necessary to frequently disassemble the spray gun for clearing the blockage, which greatly improves the working efficiency of the equipment.

[0031] Example 2

[0032] like Figures 3 to 4As shown, to make the sandblasting device suitable for pipelines, based on Embodiment 1, a collar 41 is rotatably connected to the outer wall of the gun body 31 near its nozzle. A connecting rod 42 is fixedly installed on one side of the collar 41. A slider 43 is slidably connected to the outer wall of the connecting rod 42. A connecting rod 44 is fixedly installed on one side of the slider 43. A rotating shaft 45 is rotatably connected to one side of the connecting rod 44. A nozzle 46 is fixedly installed at the lower end of the rotating shaft 45. One side of the nozzle 46 is connected to the nozzle of the gun body 31 via a flexible hose. When sandblasting is required on the inner wall of the pipeline, the nozzle 46 is pulled outward, so that the nozzle 46 and the outer wall of the connecting rod 44 form an obtuse angle. The nozzle 46 is positioned so that the abrasive mixture sprayed from the nozzle 46 can be sprayed into the pipe. During the sandblasting process, since there is an angle between the direction of the sandblasting of the nozzle 46 and the collar 41, the tangential component of the reaction force of the nozzle 46 drives the collar 41 to rotate around the gun body 31, thereby automatically sandblasting the inner wall of the pipe in all directions. When it is necessary to sandblast the outer wall of the pipe, the nozzle 46 is pulled inward so that the nozzle 46 and the inner wall of the connecting rod 44 are set at an obtuse angle, so that the abrasive mixture sprayed from the nozzle 46 can be sprayed onto the outer wall of the pipe. Similarly, the collar 41 will rotate during the sandblasting process, thereby achieving all-round sandblasting of the outer wall of the pipe.

[0033] In one optional embodiment, a plurality of positioning holes 47 are evenly arranged around the rotating shaft 45 on one side of the upper wall of the second connecting rod 44. A third connecting rod 48 is fixedly installed on one side of the upper end of the rotating shaft 45. A positioning rod 49 is threaded inside the third connecting rod 48. During the rotation of the nozzle 46, the rotating shaft 45 will rotate along with its trajectory. When the nozzle 46 is adjusted to the required position, the position of the nozzle 46 can be locked by simply rotating the positioning rod 49 so that its lower end enters the corresponding positioning hole 47.

[0034] In one alternative embodiment, the upper wall of the slider 43 is threaded with a bolt, and the lower wall of the bolt contacts the upper wall of the connecting rod 42. For pipes of different diameters, the position of the connecting rod 44 can be adjusted by pulling the slider 43, thereby changing the rotation radius of the nozzle and making it suitable for pipes of various radii.

[0035] Example 3

[0036] like Figure 5 As shown, in order to make the sandblasting device applicable to rail lines, based on Embodiment 1, an extension tube 51 is fixedly installed at the nozzle end of the gun body 31, and a flow guide shroud 52 is fixedly installed at the end of the extension tube 51. When sandblasting the rails of the rail line, the extension tube 51 is set so that the workers do not need to bend over during the sandblasting process, thus preventing the workers from suffering from lumbar strain due to long-term work.

[0037] In one optional embodiment, the guide shroud 52 has a "U" shaped structure, and its three inner walls are provided with abrasive grooves 53. The abrasive grooves 53 are connected to the extension pipe 51. When sandblasting the rail, the guide shroud 52 is placed on the outer wall of the rail. The abrasive grooves 53 on the three sides allow the abrasive to sandblast all areas of the rail at one time, improving the processing efficiency.

[0038] In an optional embodiment, dustproof guide wheels 54 are provided on the inner walls of both the left and right sides of the guide shroud 52. When sandblasting the rail, the guide shroud 52 can slide along the outer wall of the rail by providing dustproof guide wheels 54, which greatly improves the sandblasting efficiency.
