Description

Technical fields:

[0001] This utility model relates to the technical field of antifreeze spraying equipment for coal transportation, and in particular to an antifreeze spraying device for coal transportation. Background technology:

[0002] In winter railway coal transportation, the coal contains a certain amount of moisture, which can easily cause coal to freeze and stick to the car body and the bottom of the car, making unloading difficult and affecting railway transportation efficiency and safety. To prevent coal from freezing and sticking to the car body, antifreeze is sprayed inside the car body before loading. In the existing technology, the antifreeze spraying device includes a cantilever cylinder with several nozzles. Because the cantilever cylinder of this spraying device is located above the car body, it is difficult to spray the antifreeze evenly on the inner wall of the car body. The antifreeze spraying effect needs to be further improved, and the phenomenon of coal powder freezing and sticking to the inner wall of the car body still exists. Utility Model Content:

[0003] The purpose of this utility model is to provide a coal transportation antifreeze spraying device to solve the technical problem that existing coal transportation antifreeze spraying devices are unable to comprehensively spray the inner walls of the carriage.

[0004] The present invention relates to a coal transport antifreeze spraying device, which is applied to a coal transport train. The coal transport train includes several cars connected in sequence. A gantry frame is fixedly spanning the top of each car. A vertical pipe is vertically connected to the top of the gantry frame. A water pump and a ball valve are installed on the vertical pipe. A hose, an inclined pipe, and a V-shaped pipe are sequentially connected to the bottom of the vertical pipe. A spraying cylinder is horizontally installed at the end of the V-shaped pipe. The spraying cylinder is located inside the car. Several nozzles are installed at both ends and on the outer circumference of the spraying cylinder. Traveling rods are horizontally connected to both sides of the inclined pipe. A ball bearing traveling assembly is installed at the outer end of the traveling rod. The ball bearing traveling assembly travels on the gantry frame. Rollers matching the positions of the inclined pipes are rotatably connected to both ends of the top of the car.

[0005] Furthermore, an arc-shaped raceway groove is provided on the inner side of the gantry frame, and the ball bearing traveling assembly travels within the raceway groove.

[0006] Furthermore, the angle between the inclined tube and the vertical direction is 15° to 45°.

[0007] Furthermore, the ball bearing travel assembly includes a connecting post, one end of which is screwed onto the travel rod, and a blind hole is provided at the other end of the connecting post. A compression spring and a travel ball are sequentially installed in the blind hole from the bottom to the opening, and the travel ball rolls in the raceway groove.

[0008] Furthermore, a threaded through hole is horizontally provided on the raceway groove, and a limit pin is screwed into the threaded through hole. The limit pin is used to limit the lower limit travel position of the traveling rod.

[0009] Furthermore, a wear-resistant sleeve is fixedly fitted onto the inclined tube.

[0010] The beneficial effects of this utility model are as follows: Based on the traditional antifreeze spraying, this utility model designs a rotating spraying device, so that the nozzle is located inside the carriage during spraying, which can better spray the inner wall of the carriage. At the same time, this utility model can automatically cross the seam between two carriages. The design is ingenious, flexible and convenient to use, and the spraying effect is significantly improved. It is worth promoting and using on a large scale. Attached image description:

Detailed implementation method:

[0017] like Figures 1 to 3As shown, a coal transport antifreeze spraying device is applied to a coal transport train. The coal transport train includes several sequentially connected carriages 1, each including a gantry frame 2 fixedly spanning above the carriages 1. A vertical pipe 3 is vertically connected to the top of the gantry frame 2. A water pump and a ball valve are installed on the vertical pipe 3. A hose 4, an inclined pipe 5, and a V-shaped pipe 6 are sequentially connected to the bottom of the vertical pipe 3. A spraying cylinder 7 is horizontally installed at the end of the V-shaped pipe 6. The spraying cylinder 7 is located inside the carriage 1. Several nozzles 8 are installed at both ends and on the outer circumference of the spraying cylinder 7. Traveling rods 9 are horizontally connected to both sides of the inclined pipe 5. A ball bearing traveling assembly is installed at the outer end of the traveling rod 9. The ball bearing traveling assembly travels on the gantry frame 2. Rollers 14, matching the positions of the inclined pipe 5, are rotatably connected to both ends of the top of the carriage 1. The angle between the inclined pipe 5 and the vertical direction is 30°.

[0018] To ensure a smoother walking experience, such as Figure 3 As shown, an arc-shaped raceway groove 13 is provided on the inner side of the gantry frame 2, and the ball bearing traveling assembly travels within the raceway groove 13.

[0019] like Figure 4 As shown, the ball bearing traveling assembly includes a connecting post 10, one end of which is screwed onto the traveling rod 9. A blind hole is provided at the other end of the connecting post 10. A compression spring 11 and a traveling ball 12 are installed sequentially from the bottom to the opening of the blind hole. The traveling ball 12 rolls in the raceway groove 13.

[0020] like Figure 1 and Figure 2 As shown, a threaded through hole is horizontally opened on the raceway groove 13, and a limit pin 15 is screwed into the threaded through hole. The limit pin 15 is used to limit the lower limit travel position of the traveling rod 9. In order to prevent the inclined tube 5 from being worn, a wear-resistant sleeve 16 is fixedly fitted on the inclined tube 5.

[0021] In practical use, such as Figures 1 to 5 As shown, the water pump and ball valve are started. As the carriage 1 moves forward, the spray pipe 7 and nozzle 8 move relative to each other inside the carriage 1. At the same time, the nozzle 8 sprays antifreeze onto the bottom and inner walls of the carriage. When it reaches the joint between the two carriages 1, as shown... Figure 5 As shown, the wear-resistant sleeve 16 touches the roller 14, causing the inclined tube 5 and V-shaped tube 6 to rotate upward (along the travel path of the raceway groove 13), so that they can cross the seam and enter the next carriage 1. After entering the next carriage 1, due to gravity, the inclined tube 5 and V-shaped tube 6 fall back to the position of the limit pin 15, so that they can enter the spraying of antifreeze in the next carriage.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
