AI Technical Summary
When the existing car tipper is tipping over a train car, the welded patches on the sides of the car can easily get stuck in the steel structure of the tipper, making it unable to return to its original position and affecting the normal operation of the tipper.
A novel cleaning device was designed, comprising a bracket, a vibrating motor, and a rubber composite plate. The rubber composite plate, through its serrated edges and limiting buckle structure, allows it to slide under the spring rebound force at the bottom of the train car, thus avoiding jamming.
This effectively avoids the problem of the cleaning device getting stuck in the welded patch on the car side, ensuring the normal operation of the tipper and improving the reliability and ease of maintenance of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to a novel car cleaning device that does not obstruct train cars. Background Technology
[0002] A tippler is a large mechanical device used to unload open-top train cars. It typically consists of a drive unit, end rings, three main beams, a car press, and a car support plate. By tipping the car, the coal loaded inside the open-top train car is unloaded. Because coal contains moisture, it freezes and adheres to the surface of the car sides in cold winter weather. When the tippler tipps the car, the frozen coal adhering to the surface cannot fall off naturally.
[0003] Currently, the common practice is to install a car cleaner on the tipper. The car cleaner consists of a steel structure support and a vibrating motor. The high-frequency vibration of the vibrating motor applies a continuous excitation force to the car side, thereby separating the frozen coal from the car side.
[0004] For some older wagons, patches are usually welded onto the sides during maintenance and reinforcement. After the tipper has finished tipping over and all the coal loaded inside the wagon has been unloaded, the springs under the wagon release their pressure, and the wagon rises. At this time, if the patch welded onto the side is positioned correctly, it may cause the patch to jam against the steel structure of the cleaning device. After the tipper returns to the zero position, the cleaning device will not be able to return to its original position. Summary of the Invention
[0005] The problem this invention aims to solve is to provide a new type of car cleaner that does not obstruct train cars, thus overcoming the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a new type of car cleaning device that does not obstruct train cars, including a bracket, a vibrating motor and a rubber composite plate. The vibrating motor and the rubber composite plate are both fixed on the bracket. The rubber composite plate includes a base plate and a rubber plate. The rubber plate is adhered to the surface of the base plate. Both sides of the rubber plate have serrated edges, and the serrated edges have first serrations. The back of the base plate has multiple positioning plates.
[0007] The bracket has a fixing plate for fixing the rubber composite plate. The fixing plate has rectangular holes that correspond one-to-one with the positioning plate. The back of the fixing plate has a positioning lug. The positioning plate passes through the rectangular holes. Both the positioning plate and the positioning lug have pin holes. The rubber composite plate and the fixing plate are slidably connected by a pin that passes through the positioning plate and the positioning lug. The pin has a limiting hole near its end, and a limiting body is inserted into the limiting hole.
[0008] The serrated edge of the rubber plate has a limiting buckle that restricts the sliding of the rubber composite plate along the pin shaft. The limiting buckle has a C-shaped cross-section. The side of the rubber composite plate with the serrated edge and the side of the fixing plate both extend into the limiting buckle. The limiting buckle is fixed to the fixing plate by bolts. The surface of the limiting buckle that contacts the serrated edge has a second serration that can mesh with the first serration.
[0009] Optionally, the fixing plate has four rectangular holes, which are arranged in a 2*2 matrix.
[0010] Optionally, the rubber sheet is made of natural rubber.
[0011] Optionally, the limiting body in the limiting hole is a cotter pin.
[0012] Optionally, the first saw tooth and the second saw tooth both have a saw tooth height of 4 mm and a tooth profile angle of 60°.
[0013] Optionally, the maximum stroke of the rubber composite plate in the direction of the pin is 40 mm.
[0014] The advantages and positive effects of this utility model are: due to the adoption of the above technical solution, the structure is reasonably designed, which can effectively solve the problem of patch jamming when the cleaning tool is welded to the side of the vehicle, making it more convenient.

[0029] This utility model provides a novel car cleaning device that does not obstruct train cars, such as... Figure 1 As shown, the system includes a support frame 1, a vibration motor 2, and a rubber composite plate 3. Both the vibration motor 2 and the rubber composite plate 3 are fixed to the support frame 1. Figure 5 As shown, the rubber composite board 3 includes a base plate 3-2 and a rubber plate 3-1. The rubber plate 3-1 is adhered to the surface of the base plate 3-2, as shown below. Figure 4 , Figure 6 As shown, both sides of the rubber sheet 3-1 have serrated edges, and the serrated edges have first serrations 3-4. The back of the base plate 3-2 has multiple positioning plates 3-3.
[0030] like Figure 2 , Figure 3 As shown, the bracket 1 has a fixing plate 6 for fixing the rubber composite plate 3. The fixing plate 6 has rectangular holes 6-1 that correspond one-to-one with the positioning plate 3-3. The back of the fixing plate 6 has a positioning lug 6-2. The positioning plate 3-3 passes through the rectangular hole 6-1. Both the positioning plate 3-3 and the positioning lug 6-1 have pin holes. The rubber composite plate 3 and the fixing plate 6 are slidably connected by a pin 5 that passes through the positioning plate 3-3 and the positioning lug 6-2. The pin 5 has a limiting hole 4-1 near its end. A cotter pin 5 is inserted into the limiting hole 4-1.
[0031] like Figure 8 As shown, the serrated edge of the rubber sheet 3-1 has a limiting buckle 7 to restrict the sliding of the rubber composite sheet 3 along the pin shaft 5, such as... Figure 9 , Figure 10 As shown, the cross-section of the limiting buckle 7 is C-shaped. The side of the rubber composite plate 3 with the serrated edge and the side of the fixing plate 6 both extend into the limiting buckle 7. The limiting buckle 7 is fixed to the fixing plate 6 by bolts. The surface of the limiting buckle 7 that contacts the serrated edge has a second serration 7-1 that can mesh with the first serration 3-4.
[0032] In this embodiment, the bracket 1 is assembled from steel plates and angle steel by welding, with an external dimension of 928mm in length, 1425mm in height, and 525mm in thickness; the fixing plate 6 has 4 rectangular holes 6-1, each 100mm long and 56mm wide; 4 positioning lugs 6-2 are welded to the back of the fixing plate 6, each 6-2 having a hole diameter of 40mm; and 4 M12 through threaded holes are drilled on each side of the fixing plate 6.
[0033] The vibratory motor 2, model VB-20114-W, has a voltage of 380V, a power of 1.1KW, and a speed of 14300 rpm. It is fixed to the cleaning device bracket 1 with four M24*60 bolts.
[0034] The base plate 3-2 in the rubber composite board 3 is made of Q235, with a length of 928mm, a width of 265mm, and a thickness of 10mm. The surface of the base plate 3-2 is a rubber sheet 3-2 made of natural rubber, with a length of 936mm, a width of 265mm, and a thickness of 10mm. The two sides are cut into a serrated shape with a serration height of 4mm and a serration angle of 60 degrees. Four positioning plates 3-3 are welded to the surface of the base plate 3-2. The positioning plates 3-3 have openings with a diameter of 40mm. The rubber sheet 3-1 is vulcanized and adhered to the surface of the base plate 3-2.
[0035] Pin 5 has a diameter of 40mm, a length of 275mm, a tail through hole diameter of 9mm, a head cap diameter of 60mm, a thickness of 10mm, and is made of 40Cr material.
[0036] The limiting buckle 7 is made of Q235 material, with an overall size of 265mm in height, 60mm in width, and 48mm in thickness. The second serration 7-1 is 4mm high, with a tooth angle of 60 degrees and a through hole diameter of 14mm.
[0037] like Figure 11 As shown, during installation, the positioning plate 3-3 on the back of the rubber composite plate 3 passes through the rectangular hole 6-1 of the fixing plate 6 of the bracket 1. The top of the rubber composite plate 3 is flush with the top of the fixing plate 6. The shaft pin 4 passes through the positioning lug 6-2 and the positioning plate 3-3. The tail is fixed with a cotter pin 5 with a nominal diameter of 8mm. After the second serration 7-1 on the limit buckle 7 engages with the first serration 3-4 on the rubber composite plate 3, it is fixed with an M12*30 screw. During the operation of the new car cleaner, if the car side patch gets stuck with the rubber composite plate 3, due to the elasticity of the rubber plate 3-1, under the huge rebound force of the spring at the bottom of the train car, the first serration 3-4 on both sides of the rubber plate 3-1 and the second serration 7-1 of the limit buckle 7 will slide out of alignment. The positioning plate 3-3 on the back of the rubber composite plate 3 moves upward along the pin 5, moving from the bottom of the rectangular hole 6-1 to the top (e.g., Figure 12 As shown, the rubber composite plate 3 moves upward, thereby releasing the clamping resistance between the patch and the rubber composite plate 3, preventing the train car patch from getting stuck with the cleaning device. After unloading, loosen the fastening screws of the limit buckle 7, and the rubber composite plate 3 returns to its original position. Then, retighten the screws on the limit buckle 7 to restore it to its initial state.
[0038] Due to the limitation of the rectangular hole 6-1 on the car cleaner bracket 1, the maximum stroke of the rubber composite plate 3 is 40mm. Under the limitation of the hydraulic cylinder of the tipper, the maximum rebound distance of the spring at the bottom of the train car is also 40mm. Therefore, no matter where the train car patch is located, the new car cleaner will not get stuck.
[0039] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
