Description

Technical Field

[0001] This utility model relates to the field of radiator maintenance technology, and in particular to a cleaning and sandblasting tool for surface treatment of railway locomotive radiators. Background Technology

[0002] Railway locomotive radiators are an important component of the railway locomotive cooling system. They are mainly used to dissipate excess heat generated during locomotive operation to ensure that all components of the locomotive operate within a normal temperature range. The radiator transfers the heat generated by the locomotive equipment to the cooling medium through heat exchange, and then the cooling medium dissipates the heat to the surrounding environment. To improve heat dissipation efficiency, cooling fans and water pumps are usually used to force the cooling medium to flow, accelerate the heat transfer speed, effectively prevent the locomotive's engine, converter, transformer and other key equipment from being damaged due to overheating, extend the service life of the equipment, and reduce maintenance costs and downtime.

[0003] When radiators experience surface contamination, oxidation, and corrosion during long-term use and maintenance, a cleaning and sandblasting tool for railway locomotive radiators is needed to treat the surface. Among existing cleaning and sandblasting tools for railway locomotive radiator maintenance, handheld sandblasting guns and high-pressure cleaning guns are the most common forms, especially suitable for small-batch repairs, complex structural areas, and scenarios with limited space. However, when the bottom of the radiator needs maintenance, it requires manual flipping, which leads to defects in the radiator maintenance quality, shortens the radiator's lifespan, reduces its performance, and increases the frequency of radiator repair and replacement.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the radiator is placed on the fixed plate, and the cylinder is started. The output end of the cylinder is fixedly connected to the clamping plate. Since the connecting rod two is rotatably connected to the connecting shaft two, the two clamping plates will move left and right when the cylinder is started. The top of the clamping plate is equipped with a limiter. The limiter rotates on the fixed block three, which can fix radiators of different shapes. Then, the connecting shaft one is held and pulled up and down. Both ends of the connecting shaft one are fixed with pull rods, which are fixedly connected to the fixed block one. The other end of the fixed block one is rotatably connected to the fixed plate. At the same time, the connecting rod three is rotatably connected to the fixed plate. Therefore, when the connecting shaft one moves up and down, the fixed plate will flip accordingly, which makes it easier for workers to clean the dust on the surface of the radiator more thoroughly.

[0022] 2. In this utility model, when the worker is cleaning dust, the front and rear baffles will block the dust to prevent it from scattering everywhere. Then, the suction motor is started, and the front end of the suction motor generates a strong suction force, which can suck the fallen dust into the collection box. At the same time, there is an exhaust fan at the rear end of the suction motor, which can be discharged from the inner wall of the rear baffle through the ventilation pipe, effectively guiding the cleaned dust into the collection box. Because there must be no foreign objects blocking the exhaust, a filter box is set at the bottom of the collection box. The filter box has a sliding drawer inside, and the filter screen inside the drawer can effectively filter larger dust particles. The sliding design makes it convenient for the worker to clean out the full dust. Attached Figure Description

A fixing block 3 is rotatably connected to the outer wall of the pull rod 4. A connecting shaft 5 is fixedly connected to the right side of the outer wall of the pull rod 4. A dust collection mechanism 2 is fixedly connected to the top of the fixed frame 1 near the edge. The dust collection mechanism 2 is used to collect the dust generated after sandblasting.

[0034] Specifically, the cleaning and sandblasting fixture mainly consists of a fixed frame 1 as its basic support structure. Multiple fixed blocks 7 are fixedly connected to the top of the fixed frame 1. These fixed blocks 7 are evenly distributed on the top of the fixed frame 1, providing stable connection points for the installation of subsequent components. Each adjacent side of the multiple fixed blocks 7 is rotatably connected to a connecting rod 25. A fixed plate 8 is rotatably connected to the outer wall of the connecting rod 25. The fixed plate 8 is a key platform for placing the radiator. A slide rail 15 is fixedly connected to the bottom of the fixed plate 8, ensuring smooth sliding of the clamping plate 11. The top of the clamping plate 11... The front and rear fixed blocks 10 stabilize the limiters 9, the connecting rod 2 12 and the connecting shaft 2 13 rotate together, the cylinder 14 provides power, the connecting rod 1 6 and the pull rod 4 cooperate with the fixed block 1 3 and the connecting shaft 1 5, by pulling the connecting shaft 1 5 up and down, the pull rod 4 is driven to move, and the fixed plate 8 will rotate around the connecting rod 25. This design allows the operator to easily adjust the angle of the radiator, so as to more comprehensively clean and sandblast the surface of the radiator without having to manually adjust the position of the radiator repeatedly, which greatly improves the work efficiency and the convenience of operation.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The dust collection mechanism 2 includes a front baffle 202. The bottom of the front baffle 202 is fixedly connected to the top of the fixed frame 1 near the edge. A rear baffle 203 is fixedly connected to the rear side of the top of the fixed frame 1. A collection box 201 is fixedly connected to the inner wall of the fixed frame 1. A filter box 206 is fixedly connected to the bottom of the collection box 201. A plurality of sliding grooves 207 are provided on the inner wall of the filter box 206. A sliding strip 209 is slidably connected to the inner wall of each sliding groove 207. A drawer 208 is fixedly connected to the outer wall of the sliding strip 209. A filter screen 210 is fixedly connected to the bottom of the drawer 208.

A ventilation pipe 205 is connected to the rear end of the suction motor 204.

[0036] Specifically, the dust collection mechanism 2, as a crucial part of the cleaning and sandblasting fixture for the maintenance of the railway locomotive radiator, bears the heavy responsibility of efficiently collecting and processing the dust generated during the process. The rear baffle 203 and the front baffle 202 cooperate to form a relatively enclosed dust collection space. The collection box 201 adopts a well-sealed design, which can withstand a certain weight of dust accumulation and prevent dust leakage. The bottom of the collection box 201 is fixedly connected to the filter box 206, which plays a key filtering role in the entire dust collection process. The inner wall of the filter box 206 has multiple sliding grooves 207, and the inner walls of the multiple sliding grooves 207 are slidably connected to sliding... The outer wall of the sliding strip 209 is fixedly connected to a drawer 208, and the bottom of the drawer 208 is fixedly connected to a filter screen 210, which effectively intercepts fine dust particles and ensures the cleanliness of the exhaust air. The front of the filter box 206 is connected to a suction pipe 211, the rear end of the suction pipe 211 is connected to a suction motor 204, and the rear end of the suction motor 204 is connected to a ventilation pipe 205. The function of the ventilation pipe 205 is to exhaust the filtered air and guide the dust to fall accurately into the collection box 201. Through the close cooperation and coordinated work of each component, the dust collection mechanism 2 achieves efficient collection and filtration of dust generated during the cleaning and sandblasting process.

[0037] Please see the appendix Figure 1 and attached Figure 2 The bottom of the suction motor 204 is fixedly connected to the base 19, the outer wall of the ventilation pipe 205 is fixedly connected to the fixing clip 24, the bottom of the fixing frame 1 is fixedly connected to the base plate 22, the output end of the cylinder 14 is fixedly connected to the outer wall of the clamp plate 11, and the top of the base plate 22 is fixedly connected to the control board 23, which is electrically connected to the suction motor 204.

[0038] Specifically, to ensure the suction motor 204 remains stable during operation and reduce noise and potential malfunctions caused by vibration, a base 19 is fixedly connected to its bottom. A fixing clip 24 is fixedly connected to the outer wall of the ventilation pipe 205 to ensure that the ventilation pipe 205 will not shake or shift during operation. The base plate 22 is the foundation of the entire fixture, bearing the weight of the fixture and various loads generated during operation. The base plate 22 is made of high-strength material to ensure its structural stability and durability. The cylinder 14 is the key component that drives the movement of the clamping plate 11. Its output end is fixedly connected to the outer wall of the clamping plate 11. This connection method needs to ensure that the power of the cylinder 14 can be accurately and efficiently transmitted to the clamping plate 11 so that the clamping plate 11 can move according to the predetermined action. The control board 23 is electrically connected to the suction motor 204. Through this connection method, the control board 23 can accurately control the start, stop, and speed adjustment of the suction motor 204.

[0039] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 The outer wall of the base plate 22 is fixedly connected with multiple fixed feet 20, and the inner wall of each fixed foot 20 is threaded with multiple screws 21. The inner wall of the front baffle 202 is threaded with multiple screws 18, and the outer wall of the multiple screws 18 is provided with a nameplate 17. The outer wall of the connecting shaft 5 is fixedly connected with an anti-slip sleeve 16, and the outer wall of the connecting shaft 13 is fixedly connected to the middle of the outer wall of the clamping plate 11.

[0040] Specifically, to ensure that the base plate 22 can be stably placed on the work site, multiple fixed feet 20 are fixedly connected to its outer wall. During installation, screw 21 is slowly screwed into the threaded hole of the fixed foot 20. Through precise torque control, a firm connection is formed between screw 21 and fixed foot 20. Nameplate 17 is an important identification component of the tooling, which is marked with basic information and usage precautions of the tooling, so that operators can quickly understand and use the tooling correctly. The anti-slip sleeve 16 effectively avoids the slippage of connecting shaft 5 when it is running at high speed, ensuring the stability of the connection. The fixed connection between connecting shaft 23 and clamping plate 11 further enhances the rigidity and reliability of the entire tooling.

[0041] Working principle: First, place the radiator on the fixed plate 8 and start the cylinder 14. Since the output end of the cylinder 14 is fixedly connected to the clamping plate 11 and the connecting rod 2 12 is rotatably connected to the connecting shaft 2 13, when the cylinder 14 is started, the two clamping plates 11 will move left and right accordingly. The top of the clamping plate 11 is equipped with a limiter 9, which can rotate on the fixed block 3 10. In this way, radiators of different shapes can be fixed to meet diverse fixing needs. Hold the connecting shaft 1 5 and pull it up and down. Both ends of the connecting shaft 1 5 are fixed with pull rods 4, which are fixedly connected to the fixed block 1 3. The other end of the fixed block 1 3 is rotatably connected to the fixed plate 8. At the same time, the connecting rod 3 25 is also rotatably connected to the fixed plate 8. Therefore, when the connecting shaft 1 5 moves up and down, the fixed plate 8 will flip accordingly, making it easier for workers to clean the dust on the surface of the radiator more thoroughly without having to manually adjust the position of the radiator repeatedly. The operation is convenient and efficient.

[0042] Then, when the worker cleans the dust, the front baffle 202 and the rear baffle 203 can effectively block the dust and prevent it from scattering everywhere, keeping the working environment clean. When the suction motor 204 is started, its front end generates a strong suction force, which can suck the fallen dust into the collection box 201. At the same time, the rear end of the suction motor 204 exhausts the air through the ventilation pipe 205 from the inner wall of the rear baffle 203. This design can effectively guide the cleaned dust into the collection box 201, improving the dust collection efficiency. Considering that there should be no foreign objects blocking the exhaust, a filter box 206 is set at the bottom of the collection box 201. The filter box 206 has a sliding drawer 208 inside. The filter screen 210 in the drawer 208 can effectively filter larger dust particles, preventing them from entering the exhaust system and affecting the normal operation of the equipment. The drawer 208 is made to slide, which makes it convenient for the worker to clean out the dust when it is full, ensuring the continuous and effective operation of the filter box 206 and extending the service life of the equipment.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
