Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer machine technology, and more specifically, to a novel tail device for a longitudinal transfer machine. Background Technology
[0002] As a wear-prone component of transfer conveyors, sprockets require maintenance, reversal, or replacement when wear is significant or damage occurs. Replacing sprockets is a labor-intensive process, requiring the complete removal of the entire coal return hood and chain clamping blocks. If the cooperating scraper conveyor head is a cross-side unloading head frame, the scraper conveyor head turning cable trough is located above the transfer conveyor tail. In this case, replacing the sprocket would necessitate dismantling the scraper conveyor turning cable trough and the entire coal return hood at the tail of the transfer conveyor; otherwise, sprocket replacement is impossible.
[0003] Other significant problems exist at the tail section of the transfer conveyor: the flanges are also high-wear components, and their failure can lead to the complete loss of tail section functionality. However, in existing designs, the flanges are usually welded directly to the tail frame, making replacement extremely inconvenient, time-consuming, and labor-intensive. Coal tends to accumulate in the tail area, which not only affects the normal operation of the transfer conveyor but also complicates daily maintenance and cleaning. Improving equipment reliability requires considering how to conveniently and effectively remove this coal accumulation. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this utility model provides a novel tail device for a roadway transfer machine. This device enables efficient operation of sprocket maintenance, oiling, and replacement, while also enabling replaceable wing plates and coal clearing at the tail.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A novel tail section device for a transfer conveyor includes an upper guard assembly, a side guard assembly, a cover plate assembly, a side pressure block assembly, and a tail frame. The tail frame is disposed at the bottom of the upper guard assembly. The side pressure block assemblies are disposed on both sides between the upper guard assembly and the tail frame. The cover plate assemblies are disposed between the two side pressure block assemblies and are located between the upper guard assembly and the tail frame. The side guard assemblies are disposed on the side pressure block assemblies.
[0007] The upper protective cover assembly includes a U-shaped frame, an open protective cover, and an observation window. The open protective cover is disposed on the upper part of the U-shaped frame, the U-shaped frame is disposed above the side pressure block assembly, and the observation window is disposed on the top of the open protective cover.
[0008] The inner wall of the U-shaped frame is symmetrically provided with wing plates, which are welded and fixed to the U-shaped frame.
[0009] The U-shaped frame is provided with frame connecting plates on both sides, and the U-shaped frame is connected to the side pressure block assembly through the frame connecting plates.
[0010] The side pressure block assembly includes a pressure block plate, a first connecting plate, a second connecting plate, and a connecting block. The first connecting plate and the second connecting plate are respectively disposed at the top and bottom of the pressure block plate. The connecting block is fixedly disposed at the upper edge of the pressure block plate. The pressure block plate is bolted to the frame connecting plate through the first connecting plate. The pressure block plate is connected to the tail frame through the second connecting plate and the connecting block.
[0011] The pressure plate is provided with a positioning pin, and the side cover assembly is mounted on the pressure plate by means of the positioning pin.
[0012] The pressure plate is provided with a locking block, and the pressure plate is locked to both sides of the cover plate assembly by the locking block.
[0013] The side shield assembly includes a shield housing, on which a connecting hole matching the positioning pin is provided, and on the side of the shield housing away from the connecting hole a bolt hole is provided, the bolt hole being connected to the tail frame by a connecting bolt.
[0014] The protective cover housing is equipped with side cover handles.
[0015] The tail section has a bottom opening.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The upper shield assembly, side shield assembly, cover plate assembly, and side pressure block assembly are all designed as independently detachable structures, completely changing the cumbersome process of traditional designs that required removing all components above the tailstock to access and replace the sprockets. Now, only the side shield assembly, cover plate assembly, and side pressure block assembly need to be removed sequentially from a horizontal direction to quickly expose the sprocket area for repair or replacement, greatly shortening maintenance time and reducing operational complexity. The side shield assembly, with its positioning pins and single-sided bolt connection, enables rapid installation and removal, providing a direct passage for sprocket lubrication, inspection, and replacement. The wing plate is disassembled as a whole with the upper shield: the key component for chain clamping, the wing plate, is welded and fixed to the U-shaped frame, allowing it to be disassembled along with the entire upper shield assembly. This not only simplifies the replacement process of the wing plate itself, but more importantly, removing the upper shield during maintenance greatly frees up space above the tailstock, providing maintenance personnel with a more spacious and safer operating environment. As a wear-prone component, the wing plate's welded-to-the-detachable U-shaped frame design simplifies the replacement of worn wing plates, eliminating the need for larger parts and reducing maintenance costs while effectively extending the overall equipment lifespan. An opening at the bottom of the tailstock provides an effective channel for clearing accumulated coal, preventing coal dust buildup from affecting normal equipment operation. This device simplifies the sprocket repair and replacement process, comprehensively improving the equipment's maintainability, reliability, and economy, and significantly reducing maintenance difficulty and costs.
