Description

Technical Field

[0001] This utility model relates to the technical field of paint spraying equipment, specifically to a water-based paint spraying equipment for ballastless steel rails. Background Technology

[0002] With modernization, my country's railway engineering has also achieved remarkable progress, with its high-speed train mileage ranking first in the world and accounting for more than 70% of the world's total high-speed rail mileage.

[0003] With the rapid development of railway engineering in my country, the maintenance and upkeep of railway tracks cannot be ignored. Because rails are exposed to air for extended periods, their surfaces are prone to electrochemical reactions with oxygen and water vapor, leading to rust spots, scars, and other damage. Furthermore, during railway operation, rails are subjected to friction and impact from train wheelsets, which also easily causes surface wear. Without effective treatment, the long-term losses can be incalculable. Therefore, the current common practice is to use spray coatings to protect the rail surface. These coatings effectively isolate the rails from corrosive media, reduce electrochemical activity, slow down corrosion, and form a dense protective layer, reducing wear on the rail surface and extending its service life.

[0004] In actual spraying operations, the coating on a steel rail often needs to be sprayed repeatedly to achieve the required thickness and performance. This requires operators to spray back and forth many times. However, due to factors such as the uneven terrain on both sides of the track at the work site, the spraying equipment is often difficult to move on both sides of the steel rail, which affects the construction. Most existing high-speed rail tracks use ballastless tracks, which are relatively flat between the tracks. Placing the spraying equipment between the tracks makes it easier to move the equipment. However, the spraying equipment is relatively heavy and bulky. Using track wheels can make the movement more convenient, but it also brings the problem of not being able to move back and forth.

[0005] Therefore, this utility model proposes a water-based coating spraying equipment for ballastless rails, which combines a liftable rail wheel device and heavy-duty TPR rubber casters, allowing the equipment to move between rails without affecting reciprocating operations, making it more convenient for actual construction use. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the prior art by providing a water-based coating spraying device for ballastless steel rails, so as to make the spraying device easier to move during construction and easier to carry out reciprocating spraying operations.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a water-based coating spraying device for ballastless steel rails, comprising a mounting plate, a track wheel device disposed below the mounting plate, the track wheel device cooperating with the steel rail; a fuel generator disposed above the mounting plate, the fuel generator being connected to a plunger pump, the plunger pump's suction port being connected to a coating tank, and the plunger pump's outlet port being connected to a spray gun.

[0008] Furthermore, heavy-duty TPR rubber casters are provided below the mounting plate.

[0009] Furthermore, the track wheel device can be raised and lowered below the mounting plate.

[0010] Furthermore, the track wheel device includes two threaded posts, each fixedly connected to the lower part of the mounting plate. A connecting rod is provided between the two threaded posts, and collars are provided at both ends of the connecting rod. The collars are respectively fitted onto the threaded posts. A compression spring is fitted onto the threaded post above the collar, and a nut is connected to the threaded post below the collar. A connecting plate is fixedly connected below the connecting rod, and a track wheel is installed through the connecting plate. The track wheel cooperates with the rail.

[0011] Furthermore, a handrail is provided on one side above the mounting plate.

[0012] Furthermore, handles are provided on both sides above the mounting plate.

[0013] Furthermore, the suction port of the plunger pump is connected to a suction pipe, which extends into the paint bucket, and a filter is provided at the front end of the suction pipe.

[0014] The beneficial effects of this utility model are: 1. This utility model, through the cooperation of heavy-duty TPR rubber casters and track wheels, makes it more convenient and labor-saving for operators to move the equipment during operation, and is more convenient for actual operation. 2. This utility model avoids crushing the wet coating by adjusting the track wheels and raising them. The spraying device is pushed on the ground between the rails, so there is no need to remove the equipment from the rails when spraying back and forth. The ground between the rails is relatively flat, making the transfer easier. 3. Since spraying takes time, the front coating is often completely dry after the back spraying is completed. At this point, moving the equipment to the front can basically achieve seamless operation, which helps to improve work efficiency. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] Embodiments of this utility model: like Figure 1-2 As shown, in this embodiment, the paint spraying equipment of the present invention includes a mounting plate 1, heavy-duty TPR rubber casters 2 are arranged below the mounting plate 1, and the heavy-duty TPR rubber casters 2 cooperate with the ground between the steel rail 9; and a track wheel device 3 is arranged below the mounting plate 1, and the track wheel device 3 cooperates with the steel rail 9.

[0019] A threaded post 31 is provided in the track wheel device 3. There are two threaded posts 31 in each track wheel device 3. A connecting rod 32 is provided between the two threaded posts 31. A collar 321 is provided at both ends of the connecting rod 32. The collars 321 on both sides are slidably sleeved on the threaded posts 31 on both sides. A spring 33 is sleeved on the threaded post 31 above the collar 321. The spring 33 is in a compressed state. A nut 311 is provided at the lower end of the threaded post 31. The nut 311 cooperates with the collar 321.

[0020] Connecting plates 34 are fixedly installed on both sides below the connecting rod 32, and track wheels 35 are installed between the two connecting plates 34. The track wheels 35 cooperate with the rails 9.

[0021] A handrail 4 is provided on the rear side above the mounting plate 1, and handles 8 are provided on both sides above the mounting plate 1. A fuel generator 5 is fixedly installed on the side of the mounting plate 1 near the handrail 4. A plunger pump 6 is provided on the front side of the fuel generator 5, and the fuel generator 5 is connected to the plunger pump 6. The inlet of the plunger pump 6 is connected to the suction pipe 61, which extends into the paint bucket 7. A filter 63 is provided at the front end of the suction pipe 61. The outlet of the plunger pump 6 is connected to the outlet pipe 62, which is connected to the spray gun.

[0022] The principle of this utility model is as follows: This utility model is used for spraying water-based coatings on the surface of high-speed rail tracks (nowadays, most high-speed rail tracks are ballastless tracks).

[0023] During use, two or more operators use the handles 8 on both sides of the mounting plate 1 to move the spraying equipment of this utility model onto the track, so that the heavy-duty TPR rubber casters 2 are located on the ground between the tracks, and the track wheels 35 are matched with the steel rails 9.

[0024] In the above process, if the track wheel 35 is in close contact with the rail 9, the nut 311 is rotated so that the nut 311 contacts the lower side of the collar 321; if the track wheel 35 is not in contact with the rail 9, the nut 311 is rotated so that the nut 311 moves down. During the downward movement of the nut 311, the compression spring 33 tends to recover its deformation and presses the collar 321 down, causing the track wheel 35 to be in close contact with the rail 9.

[0025] At this point, paint can be prepared in paint bucket 7 (paint bucket 7 is placed on mounting plate 1 and can be freely removed). Then, the suction pipe 61 is placed into paint bucket 7, the fuel generator 5 is started and power is supplied to the plunger pump 6. At this point, the equipment starts to work. The operator holds the spray gun and adjusts the adjustment knob on the spray gun to evenly spray the paint onto the steel rail 9. This utility model relates to an airless spraying machine. In the process, the fuel generator 5, plunger pump 6 and spray gun are all relatively mature and commercially available. The structural principle will not be described in detail.

[0026] During operation, the operator can move the spraying equipment along the rail 9 by pulling the handrail 4. The process is labor-saving and convenient. However, it should be noted that the spraying equipment is used while moving backward, so as to avoid the track wheels crushing the sprayed coating.

[0027] In actual spraying operations, the paint coating often needs to be sprayed repeatedly. After a section of rail 9 is sprayed, turn nut 311 to move nut 311 upward. The upward movement of nut 311 moves the track wheel 35 upward and separates it from rail 9 (the larger diameter edge of track wheel 35 is also adjusted to be above rail 9) to avoid contact between track wheel 35 and rail 9. At this time, the entire equipment can be pushed to the front end of rail 9 via handle 4. If the coating at the front end has dried completely, turn nut 311 to make track wheel 35 contact rail 9 again and start the second spraying, and so on. If the coating at the front end has not dried completely, it is not advisable to continue construction at this time. Wait for the coating to dry completely before continuing construction.
