Abstract
The utility model discloses a central groove which is integrally cast, which belongs to the equipment for conveying the coal. The central groove adopts the structure: a middle plate is arranged at the middle part of the central groove, and the front side and the rear side of the middle plate are provided with an interface board, and a back-over plate is arranged below the middle plate, both sides of the middle plate are provided with a shovel-board ledge or a baffle-board ledge, and a left rack rail seat and a right rack rail seat are arranged on the baffle-board ledge, and a square porous board is arranged at the outer side of the baffle-board ledge and the rack rail seats, and the outer side of the rack rail seats is fixedly connected with the square porous board into a whole body, and the outer side of the baffle-board ledge is also provided with a reinforcing bar which supports the baffle-board ledge, the rack rail seats and the square porous board, and the interior of the rack rail seats is designed to be a hollow cavity, and a window with the shape and the size being matched with the inner cavity of the rack rail seats is arranged on the part, which is connected with the rack rail seats, of the square porous board. The reinforcing bar is provided with a process hole. With the structure, the central groove is convenient to be integrally cast; at the same time, not only the weight of the cast piece is reduced, but also the padding sand can be compacted, thereby ensuring the shape and the quality of the cast piece, and reducing the weaknesses such as the deformation and the sand adhering.
Description
Technical field
The utility model relates to the equipment of the conveying coal that uses in a kind of colliery, refers in particular to a kind of improvement of parts of intermediate channel of the slat conveyer through disappearance mould integral casting forming.
Background technology
The lost foam casting technology is the casting method that just grows up nearly decades, really be applied in the Foundry Production since the eighties in 20th century, but also middle findings that are applied to some simple shape more, material to part also has certain restriction, the founding casing with vacuum technology also needs specialized equipment, has therefore restricted popularizing of this foundry engieering.
Slat conveyer is the equipment of the conveying coal that uses in the colliery, and it is that the plurality of sections intermediate channel is connected the string of growing up, and is provided with the scraper plate that is driven by chain above the intermediate channel, and by scraper plate moving in intermediate channel, the coal that exploitation is come out transfers out.The equipment such as coalcutter of walking on intermediate channel also are installed above the intermediate channel.The parts of 70% in the slat conveyer are intermediate channel, and requirement can be exchanged fully between each joint of the intermediate channel of being made up of plurality of sections.Intermediate channel generally comprises tens parts such as baffle plate ledge, shovel board ledge, left rack rails seat, right rack rails seat, middle plate, square hole plate, interface board, back cover plate at least.Middle plate is positioned at the centre of intermediate channel, the both sides, front and back of middle plate are provided with interface board, be provided with back cover plate below the middle plate, the right side of middle plate is provided with the shovel board ledge, the left side of middle plate is provided with the baffle plate ledge, be set with left and right rack rails seat above the baffle plate ledge, the outside of baffle plate ledge and left and right rack rails seat is set with the square hole plate, captive joint with the square hole plate and be integral in the outside of left and right rack rails seat, also be set with the reinforced rib of the monoblock of supporting baffle ledge, rack rails seat, square hole plate in the outside of baffle plate ledge.
The intermediate channel of the slat conveyer of current market sale and use adopts welded structure or cast-weld construction always, and the major defect of these manufacture methods is because the resistance to abrasion of welding assembly is too low, and causes the service life of intermediate channel too short.If wear resisting property and service life that intermediate channel uses the wear-resistant steel integral casting forming just can improve intermediate channel greatly.But because the structure of intermediate channel is too complicated, if just simply each unit construction of intermediate channel is cast as one, exist distortion big, can not casting etc. shortcoming, need carry out part to its structure to improve, could casting.The present intermediate channel of the cast-weld construction that uses on the coal mine scraper machine, be with the square hole plate of monoblock be welded on left and right rack rails seat the outside, baffle plate ledge above.When if this structure adopts integral casting forming, left and right rack rails seat and baffle plate ledge just form a thick big block between just, can make other parts that very big distortion takes place, even cracking, can not global formation.
The utility model content
The utility model technical issues that need to address provide a kind of distortion little, be easy to the as cast intermediate channel.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of cast-in-block intermediate channel comprises baffle plate ledge, shovel board ledge, left rack rails seat, right rack rails seat, middle plate, square hole plate, interface board, back cover plate; Middle plate is positioned at the centre of intermediate channel, the both sides, front and back of middle plate are provided with interface board, be provided with back cover plate below the middle plate, the right side of middle plate is provided with the shovel board ledge, the left side of middle plate is provided with the baffle plate ledge, is provided with left and right rack rails seat above the baffle plate ledge, and the outside of baffle plate ledge and left and right rack rails seat is the square hole plate, captive joint with the square hole plate and be integral in the outside of left and right rack rails seat, also be set with the reinforced rib of supporting baffle ledge, rack rails seat, square hole plate in the outside of baffle plate ledge.The cavity of hollow is arranged in rack rails seat inside, and square hole plate and rack rails seat bonded assembly position have and the corresponding window of inner chamber, and the size of window is consistent with the inner chamber of rack rails seat with shape.
Described reinforcing rib design becomes the reinforced rib of band auxiliary hole.
Owing to adopted technique scheme, the obtained technological advance of the utility model is:
Baffle plate ledge reinforced rib and rack rails seat and square hole plate connecting bridge are made auxiliary hole, for the inblock cast intermediate channel provides convenience, so both alleviated the weight of foundry goods itself, well back-up sand, consolidation have again guaranteed the quality of foundry goods.
The reinforced rib of the baffle plate ledge in the intermediate channel of cast-weld construction is an entity structure all, does not have the hole.It is unreal that such structure the time can produce back-up sand in casting, perhaps can't back-up sand, and cause the scab situation serious.The hole is set on reinforced rib sand is passed through smoothly, guarantee the shape of foundry goods, reduce distortion, prevent to produce defectives such as scab.
