[0001] The utility model relates to the technical field of coke oven production auxiliary equipment, in particular to a coke oven dust removal pipeline belt snow clearing device. Background Art

[0002] At present, there is no snow clearer on the dust removal pipe belt on the coke side of the coke oven machine. After snowing in winter, during the movement of the coke blocking car and the coke pushing car, the accumulated snow is drawn into the reel of the dust removal trolley of the dust removal pipe belt, causing the belt to deviate and even be damaged, affecting the normal production of the coke oven.

[0003] Currently, snow is removed manually from the belts of the coke-side dust removal ducts of coke ovens. However, this process is time-consuming, disrupting normal production and incurring high labor costs. Furthermore, it is not possible to install protective railings on the coke oven dust removal ducts, and manual snow removal poses a safety hazard of slipping and falling. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a coke oven dust removal duct belt snow clearing device.

[0006] A coke oven dust removal duct belt snow clearing device comprises a control mechanism, a lifting mechanism and a snow clearing mechanism;

[0007] The control mechanism includes an operating button, which is installed in the driver's cab of the coke blocking car or the coke pushing car;

[0008] The lifting mechanism includes a hydraulic cylinder, a wire rope pulley, a wire rope, a first fixed seat, and a second fixed seat. The first fixed seat is fixedly connected to one side of the frame of the belt dust removal trolley, and the second fixed seat is fixedly connected to the other side of the frame of the belt dust removal trolley.

The two connecting blocks are respectively fixedly connected to the two sides of the frame of the belt dust removal trolley, and the two ends of the rotating shaft are respectively rotatably connected to the two connecting blocks. The two ends of the angled connecting frame are respectively fixedly connected to the two ends of the rotating shaft, the angled snow clearing strip is fixedly connected to the angled connecting frame, the wire rope connecting piece is fixedly connected to the position of the angled connecting frame near the corner, and the other end of the wire rope is fixedly connected to the middle of the wire rope connecting piece.

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figures 1 to 3 As shown, the coke oven dust removal duct belt snow clearing device provided by the embodiment of the utility model includes a control mechanism 1, a lifting mechanism 2 and a snow clearing mechanism 3;

[0026] The control mechanism 1 includes an operating button installed in the driver's cab of the coke intercepting car or the coke pushing car;

[0027] The lifting mechanism 2 includes a hydraulic cylinder 2-1, a wire rope pulley 2-2, a wire rope 2-3, a first fixed seat 2-4, and a second fixed seat 2-5. The first fixed seat 2-4 is welded to one side of the frame of the belt dust removal trolley 4, and the second fixed seat 2-5 is welded to the other side of the frame of the belt dust removal trolley 4. The cylinder body of the hydraulic cylinder 2-1 is welded to the first fixed seat 2-4, and the wire rope pulley 2-2 is welded to the second fixed seat 2-5. The piston rod of the hydraulic cylinder 2-1 is fixedly connected to one end of the wire rope 2-3 through a pin shaft. The rope body of the wire rope 2-3 is wound around the wire rope pulley 2-2. The operation button is electrically connected to the hydraulic cylinder 2-1;

[0028] The snow-clearing mechanism 3 includes an angular connecting frame 3-1, a rotating shaft 3-2, two connecting blocks 3-3, an angular snow-clearing strip 3-4 and a wire rope connector 3-5. The two connecting blocks 3-3 are respectively welded to the two sides of the frame of the belt dust removal trolley 4, and the two ends of the rotating shaft 3-2 are respectively rotatably connected to the two connecting blocks 3-3. The two ends of the angular connecting frame 3-1 are respectively welded to the two ends of the rotating shaft 3-2. The angular snow-clearing strip 3-4 is fixedly connected to the angular connecting frame 3-1. The wire rope connector 3-5 is welded to the angular connecting frame 3-1 near the corner. The other end of the wire rope 2-3 is fixedly connected to the middle part of the wire rope connector 3-5 through a pin.

[0029] The electrical connection between the operating button and the hydraulic cylinder 2 - 1 means that when the operating button is pressed, the hydraulic cylinder 2 - 1 can be controlled to work.

[0030] During a specific implementation, when snow falls and a certain thickness of snow accumulates on the coke-side dust removal duct belt of the coke oven, the driver of the coke interceptor or pusher presses an operation button in the driver's cab. At this point, the hydraulic cylinder 2-1 begins to operate, and its piston rod extends through the wire rope pulley 2-2 and wire rope 2-3 to lower the angled connecting frame 3-1. This causes the angled connecting frame 3-1 to be parallel to the belt 5 and the angled snow-clearing strips 3-4 to contact the belt 5. The coke interceptor or pusher then moves, driving the belt dust removal trolley 4 to move. The movement of the belt dust removal trolley 4 drives the belt snow-clearing device of the coke oven dust removal duct to move, clearing the snow from the belt 5 during movement. This automatically clears the snow from the belt 5, ensuring stable production of the coke oven and reducing labor intensity for workers. After the snow is cleared, the piston rod of the hydraulic cylinder 2-1 retracts, driving the angled connecting frame 3-1 to rotate upward 90°, bringing it perpendicular to the belt 5, thereby preventing interference with the normal operation of the belt 5. This utility model has the advantages of reasonable design, compact structure, and high space utilization.

[0031] In another embodiment, the control mechanism 1 further includes two oil pipes, a hydraulic valve assembly oil tank, and a hydraulic pump. The hydraulic valve assembly oil tank is connected to the oil inlet of hydraulic cylinder 2-1 via one oil pipe, and the hydraulic pump is mounted on this oil pipe. The other oil pipe has two ends connected to the oil return port of hydraulic cylinder 2-1 and the hydraulic valve assembly oil tank, respectively. The hydraulic valve assembly oil tank supplies oil to hydraulic cylinder 2-1 via one oil pipe and the hydraulic pump. Oil return from hydraulic cylinder 2-1 returns to the hydraulic valve assembly oil tank via another oil pipe.

[0032] In another embodiment, Figure 4 As shown, the lifting mechanism 2 further includes a fan-shaped shield 2-6, one end of which is fixedly connected to the central axis of the wire rope pulley 2-2, and the other end of which is located outside the edge of the wire rope pulley 2-2. The wire rope 2-3 is located in the gap between the fan-shaped shield 2-6 and the wire rope pulley 2-2. The fan-shaped shield 2-6 can prevent the wire rope 2-3 from slipping off the wire rope pulley 2-2.

[0033] In another embodiment, the width of the angular snow-clearing strip 3-4 is greater than the width of the angular connecting frame 3-1, ensuring that the angular snow-clearing strip 3-4 contacts the belt 5 when clearing snow, while the angular connecting frame 3-1 does not contact the belt 5, thereby preventing the angular connecting frame 3-1 made of steel or iron from scratching the belt.

[0034] In another embodiment, the angled snow-clearing strip 3-4 is fixedly connected to the angled connecting frame 3-1 by bolts and nuts. Fixing the angled snow-clearing strip 3-4 to the angled connecting frame 3-1 by bolts and nuts not only facilitates installation, but also allows the angled snow-clearing strip 3-4 to be replaced with a new one by removing the bolts and nuts when the angled snow-clearing strip 3-4 becomes worn after use for a period of time, thus making operation simple and convenient.

[0035] In another embodiment, the material of the angular snow-clearing strips 3 - 4 is rubber. By using the angular snow-clearing strips 3 - 4 made of rubber, it is possible to prevent the angular snow-clearing strips 3 - 4 from scratching the belt 5 during the snow-clearing process.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
