Description

Technical Field

[0001] The present application relates to the technical field of dust collection, for example, to a track gap dust collection device. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Currently, in industries such as steel smelting, coke oven coking, and coal-fired power generation, rail-mounted vehicles and other equipment are commonly used to transport coal and coke. For example, the coke pushers, coal loading cars, smoke guide cars, and coke interceptors used in coke oven production all utilize rail-mounted transport equipment. This inevitably results in dust, such as coke dust, being deposited on the ground during transportation. Conventional floor cleaning and vacuuming equipment can only handle dust on flat surfaces, but cannot handle dust accumulated between and on the sides of the tracks. This requires manual cleaning, which is time-consuming, labor-intensive, and difficult to maintain. This not only pollutes the environment but also increases labor costs. Dust accumulation can also lead to wear and damage to equipment track wheels and other production safety issues.

[0004] Therefore, it is necessary to develop a track dust removal and collection device that can ensure the cleanliness of the track gap during equipment operation. Utility Model Content

[0005] The present application provides a track gap dust collection device to solve the technical problem that dust such as coke powder generated when using track-type transportation equipment for production falls and is deposited in the track gap, which is difficult to clean.

[0039] In this embodiment, the cleaning unit includes a first air knife and a second air knife, and the installation direction faces the direction of vehicle travel; the first air knife adopts a 200-type air knife 4, which is placed on both sides of the rail track 1, and is connected to the rail gap dust collection cover 2 through hexagonal bolts. Compressed air is connected to the outside through a hose, which is mainly used to blow up the smoke and dust on both sides of the rail track 1 through compressed air, and then suck it out through a negative pressure pipeline to achieve the purpose of cleaning the dust inside the rail gap.

[0040] The second air knife adopts a 100-type air knife, which is placed on the top of the rail 1 and connected to the rail gap dust collection cover 2 through a hexagonal bolt. Compressed air is connected to the outside through a hose. It is mainly used to blow up the smoke and dust on the top of the rail with compressed air, and then suck it out through the negative pressure pipeline to achieve the purpose of cleaning the dust on the top of the rail;

[0041] The lifting unit is located at the front and rear ends of the dust collecting unit and is an actuator for automatically lifting the track gap dust collecting cover 2 when the unit is not in operation.

[0042] In this embodiment, the lifting unit is specifically a pull-rod cylinder 9, the cylinder barrel is connected and fixed to the bracket base of the track gap dust collecting cover 2 by a hexagonal bolt, and the end of the cylinder rod is connected to the lifting guide and rail wheel bracket 7 by a hexagonal bolt;

[0043] The walking unit is a track guide wheel group 8, which is located at the front and rear ends of the dust collecting unit; the top of the track guide wheel group 8 is connected to the lifting guide and rail wheel bracket 7 through a hexagonal bolt. When working, the wheel group is placed on the track, which can better stabilize the movement of the entire system and not be offset by the movement of the vehicle body.

[0044] In this embodiment, the sealing unit is a soft rubber sealing strip, specifically including a bottom rubber sealing strip 13, an air knife end rubber sealing strip 14 and a side end rubber sealing strip 15;

[0045] Among them, the bottom rubber sealing strip 13 is connected to the bottom of the track gap dust collection cover 2 through hexagonal bolts and the sealing strip pressure plate 12. The material is wear-resistant rubber material. The bottom is adjusted to fit tightly with the ground by adjusting the lifting position height, so that the dust collection effect is better.

[0046] The rubber sealing strip 14 at the air knife end is connected to the air knife side of the track gap dust collection cover 2 through a hexagonal bolt and a sealing strip pressure plate 12; the rubber sealing strip 14 at the air knife end needs to be specially made according to the track model and size when used, and its shape is tilted outward at a certain angle to block the dust blown by the air knife, and also to better seal the track gap dust collection cover 2 and the rail track 1.
