[0003] During the laying of railway tracks, it is necessary to perform anti-corrosion treatment on the welds. However, railway tracks are set on the ground and are heavy and inconvenient to move, so the above-mentioned devices are not suitable. Manually spraying anti-corrosion liquid requires wrapping around the weld, which is difficult, time-consuming, labor-intensive, and inefficient. Therefore, there is an urgent need for a railway track weld anti-corrosion treatment device. Utility Model Content

The elastic mechanism includes slide rods. Two sets of slide rods are fixedly installed on one set of grips, and the other set of grips is movably sleeved on the two sets of slide rods.

[0006] Preferably, the elastic mechanism further includes a connecting block and a spring.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a rail weld anti-corrosion treatment device, including a gripping rod 1, a spraying mechanism 4, and a spring mechanism 3. There are two sets of gripping rods 1, and an arc-shaped diverter plate 2 is fixedly installed at the bottom of each set of gripping rods 1. The spraying mechanism 4 is disposed on the two sets of arc-shaped diverter plates 2 and is used to spray anti-corrosion liquid onto the rail weld. A linear laser light 5 is fixedly installed on the inner wall of one set of arc-shaped diverter plates 2, and a proximity switch 6 is fixedly installed on the outer surface of one side of one set of gripping rods 1. A battery 7 is fixedly installed on the other side of the outer surface of the device. Each of the two sets of grips 1 has an arc-shaped opening, and a set of sponge pads 8 are fixedly installed on each of the two sets of arc-shaped openings. Through the linear laser light 5, lines can be projected on the rail before spraying to help the user judge the spraying position and avoid spraying position deviation. At the same time, under the action of the proximity switch 6, the solenoid valve 45 can be automatically opened for spraying when the two sets of grips 1 are squeezed, and automatically closed when they are separated. The operation is convenient, ensuring the effect of the device and facilitating the promotion and use of the device. The elastic mechanism 3 is set on the two sets of grips 1. The elastic mechanism 3 includes slide rods 31. Two sets of slide rods 31 are fixedly installed on one set of grips 1, and the other set of grips 1 is movably sleeved on the two sets of slide rods 31.

[0018] The elastic mechanism 3 also includes a connecting block 32 and a spring 33. A connecting block 32 is fixedly installed on one end of each of the two sets of slide rods 31. A spring 33 is sleeved on each of the two sets of slide rods 31. One end of each set of springs 33 is fixedly connected to the corresponding connecting block 32, and the other end of each set of springs 33 is fixedly connected to the corresponding grip rod 1.

[0019] The spraying mechanism 4 includes nozzles 41, a flow divider block 42, a delivery hose 43, a connecting hose 44, and a solenoid valve 45. At least two sets of nozzles 41 are fixedly installed on the inner walls of each of the two sets of arc-shaped flow dividers 2. Each set of nozzles 41 communicates with the interior of the corresponding arc-shaped flow divider 2. A flow divider block 42 is provided between the two sets of arc-shaped flow dividers 2. A delivery hose 43 communicating with the interior of the flow divider block 42 is fixedly connected to its rear outer surface. A connecting hose 44 is fixedly connected between the flow divider block 42 and each of the two sets of arc-shaped flow dividers 2. The two sets of connecting hoses 44... Each end is connected to the interior of the diversion block 42 and the interior of the corresponding arc-shaped diversion plate 2. The diversion block 42 is equipped with a solenoid valve 45. Through the cooperation of the grip rod 1, the arc-shaped diversion plate 2, the elastic mechanism 3 and the spraying mechanism 4, squeezing the two sets of grip rod 1 can quickly surround the weld seam with the two sets of arc-shaped diversion plates 2, so that each nozzle 41 forms a circle around the weld seam for all-round simultaneous spraying. The spraying speed is fast and the spraying is comprehensive. It solves the problems of manual spraying of anti-corrosion liquid requiring a circle around the weld seam, which is difficult to operate, time-consuming and labor-intensive, and has low processing efficiency, thus improving the practicality of the device.

[0020] Working principle: The delivery hose 43 is connected to the pump in a portable small anti-corrosion liquid tank. The user holds two sets of handles 1. When the weld is found, the user places the two sets of arc-shaped diverter plates 2 between the rails. After confirming the position, the user squeezes the two sets of handles 1. One set of handles 1 slides relative to the other set of handles 1 through two sets of sliding rods 31, so that the two sets of handles 1 are close to each other. The two sets of springs 33 are stretched until the two sets of arc-shaped diverter plates 2 fit together and cover the weld. At this time, the proximity switch 6 contacts the corresponding handle 1. The distance between the two sets of handles 1 reaches the set threshold detected by the proximity switch 6, so that the solenoid valve 45 opens. The anti-corrosion liquid is sprayed out from the nozzles 41 on the two sets of arc-shaped diverter plates 2 through the delivery hose 43 and the two sets of connecting hoses 44, and sprays the weld all over.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
