Description

Technical Field

[0001] The invention belongs to the technical field of ballast cleaning equipment, and specifically relates to a ballast cleaning device. Background Art

[0002] Ballast is coarse gravel or crushed stone used to pave the road or railway bed. The stone is made of special granite. It is used to distribute the weight of the train and the track on the roadbed, which can reduce the vibration and noise caused by the passing train. After long-term use of ballast, the ballast under the railway will begin to slurry and ooze mud, especially in the rainy southern regions. The slurry and mud of the ballast seriously affects the safety of train operation.

[0003] At present, the problem of ballast mud and slurry is mostly solved by using large-section ballast cleaning machines or manual operations. Since the existing large-section ballast cleaning machines do not have a mobile device, such as the RM80 full-section ballast cleaning machine, a large tractor is required for towing and moving when in use. Due to the large size of the locomotive, it is difficult to operate in special occasions. If a large-section ballast cleaning equipment is used in a small-section ballast cleaning operation, various resources will be wasted and the economy is low. If the ballast is cleaned manually, a large amount of human resources will be required during the cleaning operation, and the ballast cleaning efficiency and automation are low, and the safety is very poor. Summary of the invention

[0004] The invention provides a ballast cleaning device to at least solve some of the above technical problems.

[0005] To achieve the above purpose, the technical solution adopted by the invention is as follows:

[0007] Furthermore, the scraper chain includes a plurality of chain rails which are rotatably connected to each other and form a ring structure. The chain rails include a pair of chain plates arranged in a mirror image, a connecting sleeve arranged between the two chain plates, and a pin which is inserted between the two chain plates and adapted to the connecting sleeve; a connecting groove connected to the driving mechanism is formed between the inner wall of the chain plate, the connecting sleeve and the pin, and the cleaning mechanism is installed on the chain plate.

[0008] Furthermore, a connecting clearance groove is respectively provided at both ends of the chain plate, one of the connecting clearance grooves is provided with a plug-in clearance hole connected to the connecting sleeve, and the other connecting clearance groove is provided with a plug-in hole adapted to the latch.

[0009] Furthermore, a threaded mounting hole for a cleaning mechanism is provided on the chain plate, and the cleaning mechanism is mounted on the chain plate by bolts.

[0010] Furthermore, the cleaning mechanism includes a plurality of mounting plates detachably mounted on the scraper chain, a plurality of scraper teeth mounted on the mounting plates, and a chain baffle plate mounted on the scraper chain and located between two adjacent mounting plates.

[0011] Furthermore, a plurality of mounting grooves adapted to the slag scraper teeth are arranged side by side on the mounting plate, and the slag scraper teeth are fixed in the mounting grooves.

[0012] Furthermore, the driving mechanism includes a driving mounting seat arranged on the mounting frame, a driving motor arranged in the driving mounting seat, and a transmission sprocket arranged on the output end of the driving motor and connected to the slag scraping chain.

[0013] Furthermore, a motor mounting groove matched with the driving motor is formed on the driving mounting seat, and a cover plate for sealing the motor mounting groove is provided on the driving mounting seat. The driving motor is installed in the motor mounting groove and sealed by the cover plate.
