Abstract
The utility model discloses a tail beam coal caving mechanism of a top coal caving hydraulic support. The tail beam coal caving mechanism comprises a tail beam, a spile inserted into the tail beam, a spile jack and a tail beam jack, wherein the tail beam is of an integrated five-box-type structure formed by a top plate, a cover plate, side protecting plates, and four main rib plates vertically arranged between the top plate and the cover plate along the longitudinal direction, the rear part of the tail beam is provided with a reinforcing ring along the circumferential direction, the spile is of an integrated five-box-type structure which is in plug-in mounting fit with a gap of the tail beam for use and is formed by three closing boxes, two opening boxes and a rear end plate, and reinforcing connecting plates of box-type structures are arranged at the joints between the rear end plate and the closing boxes as well as the joints between the rear end plate and the opening boxes. The tail beam coal caving mechanism has the advantages that the tail beam and the spile are both of the five-box-type structure form, so that the bending strength is high, the structure is stable, the structure rigidity of the tail beam and the spile can be effectively improved, collision damage to the tail beam and the spile by large sized coal and large gangue on a scraper conveyor at the rear part is avoided, complex and changeable severe working conditions in underground coal mining can be coped with, and the tail beam coal caving mechanism is safe and reliable.
Description
Technical field
The utility model relates to the caving roof coal hydraulic support that comprehensive mechanized coal mining face is used, and especially relates to a kind of roof caving coal hydraulic support tail beam Fang Mei mechanism.
Background technology
The tail boom Fang Mei mechanism of China's coal-face caving roof coal hydraulic support used is that tail boom and board plug structure are three box-structures substantially at present, three boxes that are tail boom are comprised of two long interior main muscle and two side guard boards and top board, cover plate, two outer main muscle are short main muscle patterns, three boxes distribute basically identical, but middle box cannot be sealed owing to will assembling plate jack, and reinforcing rib cannot be arranged in inside, this structure has weakened the flexural strength of tail boom integral body; Three boxes of plate are comprised of two of both sides sealing boxes and middle opening boxes, and middle box opening is also due to due to assembling plate jack, and three boxes are independent to be respectively connected with end plate, the wider and rigidity of middle box a little less than.The tail boom of this three boxes, board plug structure, in use, while having coarse coal or spoil to fall on the scrapper conveyor of rear portion, very easily cause the normal situation about using of the impacts such as plate bulk deformation, tail boom deckle board cracking to occur, and causes production efficiency to decline.
Summary of the invention
The utility model object is to provide a kind of Stability Analysis of Structures, safe and reliable roof caving coal hydraulic support tail beam Fang Mei mechanism.
For achieving the above object, the utility model can be taked following technical proposals:
Roof caving coal hydraulic support tail beam Fang Mei described in the utility model mechanism, comprise tail boom, be inserted into the plate in described tail boom and be arranged on the plate jack in plate and be arranged on the tail boom jack on tail boom, described tail boom comprises by top board, cover plate, side guard board and is longitudinally vertically set on integral type five box-structures that four main gussets between described top board and cover plate form, and on edge, described tail boom rear portion, has been arranged circumferentially stiffening ring; Described plate comprises integral type five box-structures that consist of three fully sheathed cases, two opening boxes and end plate that are used in conjunction with tail boom gap plug-in mounting, at described fully sheathed case and opening box, is positioned at reinforced company's fishplate bar that end plate joining place is provided with box-structure.
At described tail boom rear portion, be positioned at and on middle housing, be provided with tail boom jack ear seat; The cylinder barrel end of described tail boom jack and described tail boom jack ear seat are hinged, and its tailpiece of the piston rod and caving shield are hinged.
Described plate jack is arranged in the opening box on plate, its cylinder barrel end be arranged on the corresponding casing chamber of tail boom in plate jack ear seat hinged, its tailpiece of the piston rod is hinged with the rear end of corresponding opening box.
The utility model advantage is that tail boom and plate are five box-structure forms, flexural strength is high, Stability Analysis of Structures, can effectively improve the rigidity of structure of tail boom and plate, prevent coarse coal and the damaged in collision of large spoil to tail boom and plate on the scrapper conveyor of rear portion, can tackle the bad working environments that down-hole coal excavation is complicated and changeable, safe and reliable.
