Abstract
The utility model relates to a self-moving device for cushion frames of a scraper conveyor for the comprehensive extraction of a thin coal bed. The prior art lacks a moving device for the tail part and the cushion frames of the conveyor; and in order to fill the blank of the prior art, the self-moving device for the cushion frames of the scraper conveyor for the comprehensive extraction of the thin coal bed comprises a push box body, wherein the front end of the push box body is provided with a connection block; pin holes are formed in the connection block; moreover, connection pins are arranged on the connection block; the connection block is installed on the matching cushion frames of the scraper conveyor through the connection pins; the rear end of the push box body is provided with a push beam; and the push beam is arranged ahead of a push jack of an end support, and further pushed by the push jack to advance. The self-moving device for the cushion frames of the scraper conveyor for the comprehensive extraction of the thin coal bed provided by the utility model has the advantages of simple structure and convenience in use, thereby being widely applicable for being used in coal mines.
Description
Technical field
The utility model relates to a kind of thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device.
Background technology
1674 work planes are the first thin coal bed fully-mechanized mining face of Beisu mine, about 0.9 meter of coal seam thickness, cutting eye arranges by coal seam thickness, handpiece of scraper conveyer, drive end unit are suspended on crossheading, producer is safe and reliable for guaranteeing conveyer, under conveyer head, drive end unit, respectively install a cushion frame, in order to ensure conveyer drive end unit and poppet migration, need to design and produce a thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device.And prior art lacks related device.
The utility model content
The technical problems to be solved in the utility model is how to fill up the above-mentioned blank of prior art, and a kind of thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device is provided.
For solving the problems of the technologies described above, this thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device, it is characterized in that: comprise the passing casing, wherein pass the casing front end and be provided with contiguous block, have pin-and-hole on this contiguous block, and be furnished with the connection pin, be installed on the adapted drag conveyor poppet by connecting pin, pass box back and be provided with pushing beam, this pushing beam is arranged on the place ahead of the advancing jack of face end support, and is promoted to move ahead by advancing jack.
So design, when needing mobile scraper conveyer poppet, take face end support as fulcrum, the advancing jack by face end support protracts, and promotes the drag conveyor poppet from moving, and is very convenient.
As optimization, have altogether two pin-and-holes on the described contiguous block, be furnished with two and connect pin.So design is connected firmly, and is easy for installation.
As optimization, described passing casing main body is wedge shape, and its longitudinal cross-section is trapezoidal.So design, mechanical strength is large.
The utility model thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device has advantage simple in structure, easy to use, and extensively applicable coal mine uses.
Description of drawings
Below in conjunction with accompanying drawing this thin coal bed fully-mechanized mining scraper conveyor poppet self-advancing Device is described further:
