Description

Technical Field

[0001] The invention belongs to the technical field of railway maintenance, and in particular relates to a railway track bed dust removal device. Background Art

[0002] With the construction of China's high-speed rail, the initial high-speed rail has entered the maintenance stage. The railway track bed is exposed to the outside for a long time, and it is inevitable that dirt will remain on the surface of the track bed. This not only affects the environment along the railway, but also affects the safe operation of railway vehicles. For example, the residual dirt may damage the sensors or other electronic components at the bottom of the vehicle, causing vehicle failure or even accidents. The long-term accumulation of dirt will also bury the rails and cause the track bed to harden, endangering the safety of train operation. Therefore, dust removal and cleaning are very important. At present, most of the dust removal work is done by manpower, and some are done by conventional vacuum cleaners. The dust removal effect is not good, and the sucked dirt is collected manually, which is labor-intensive and inefficient. Summary of the invention

[0010] Furthermore, the vacuum cleaner head is integrally arranged with the main body, and the vacuum cleaner head is connected to the base plate via a traction rope.

[0011] Furthermore, an elastic sealing ring is embedded at the outlet of the main body, and the inlet of the dust storage tank and the outlet of the main body are sealed by the elastic sealing ring.

[0012] Furthermore, the elastic sealing ring is gradually narrowed in a direction away from the dust storage tank so that the cross section of the elastic sealing ring is V-shaped.

[0013] Furthermore, a storage table for storing the vacuum cleaner head is installed on the base plate, and the traction rope is arranged on the storage table.

[0014] Furthermore, a cantilever is provided on the base plate, a working portion of the cantilever extends in a direction away from the base plate and is connected to the vacuum cleaner head via a lifting hoist at its end.

[0015] Furthermore, the lifting device is a hydraulic cylinder.

[0016] Furthermore, the dust removal device also includes a control unit, and a detection device for detecting the amount of dirt in the dust storage tank is installed on the dust storage tank. The detection device, the driver of the hydraulic cylinder, and the driver of the dust collector assembly are electrically connected to the control unit respectively.

[0019] 2. The railway track bed dust removal device of the present invention has a dust collector head with a yielding clamping portion adapted to the rails, which not only has a guiding function but also provides favorable conditions for achieving comprehensive dust collection without omissions.

[0020] 3. In the railway track bed dust removal device of the present invention, the cross section of the elastic sealing ring is V-shaped, which is convenient for plugging the dust storage tank and the main body and prevents the effect from being affected by displacement during the docking process.
