Abstract
The utility model discloses a chute of a forge-weld double middle plate type structure, and particularly relates to a chute of a forge-welding double middle plate type structure, wherein the chute is high in working efficiency, small in abrasion and reliable in strength. The chute is provided to solve the technical problems in the prior art that an existing middle trough of a cast-weld structure is low in structural strength, poor in abrasion resistance, instable in quality and limited in coal-transferring amount. The chute of the forge-welding double middle plate type structure comprises a middle plate, a bottom plate, vertical blocking plates arranged on the two sides of the middle plate, vertical shovel plates arranged on the two sides of the bottom plate and between the middle plate and the bottom plate, and coal shoveling plates arranged on the outer sides of the vertical shovel plates. The vertical shovel plates are in the form of panels. The chute of the forge-weld double middle plate type structure is large in coal-transferring amount, good in abrasion resistance, simple in structure and high in reliability.
Description
Technical field
The utility model relates to a kind of intermediate channel, be specifically related to that a kind of work efficiency is high, wearing and tearing less, the smithwelding of intensity failure-free two in plate structure chutes.
Background technology
The structural shape of current domestic middle part chute is mainly cast-weld construction, has following shortcoming: the intensity of chute is along with the wearing and tearing of middle plate sharply decline; The mode that can only take built-up welding to repair after the middle plate wearing and tearing of chute, cannot change, and the coal amount excessively that built-up welding reparation increases is limited; The ramp plate resistance to abrasion of chute is poor, can not ensure that coalcutter walks at predetermined state; The amount of deflection (vertical, level) of chute ensures by cast component, but reality is unreliable; Plate interface serious wear in chute; The shape of base plate is unfavorable for reducing the wearing and tearing of scraper plate and base plate, and has larger go back to coal space; Ledge wear resisting property does not mate with middle plate; Casting quality is unstable; Crucial weld seam is faced with direct wearing and tearing.
Utility model content
The technical problems to be solved in the utility model be the cast-weld construction intensity of current intermediate channel low, wear no resistance, quality is unstable, it is limited to cross coal amount, provide a kind of cross coal amount is large, resistance to abrasion good, simple in structure, reliability is high smithwelding two in plate structure chutes.
For achieving the above object, the utility model adopts following technical proposals:
Plate structure chutes during a kind of smithwelding is two, comprise middle plate, base plate, shovel riser between the gear riser of middle plate both sides, both sides and middle plate and base plate at base plate, are positioned at the ramp plate in shovel riser outside, and described shovel riser be flat board.
Described middle plate is double-decker, comprises plate and lower plate in work.
Described middle plate is taken interface and is adopted W type structure.
Described ramp plate is high-strength abrasion-proof steel plate.
Described base plate adopts v-shaped structure.
Adopt the utility model after said structure, have the following advantages: shovel riser is for dull and stereotyped, simple in structure, be convenient to manufacture, specific contact pressure is little, wear-resistant; Adopt double-deck middle plate, improved the intensity of chute; In addition, in the work of middle plate, plate welds, replaceable, and crossing coal amount can be multiplied, and work efficiency is high; Middle plate is taken interface and is adopted W type structure, can first sacrifice the wearing and tearing of plate in a part, protects major part to take interface and is not worn; Weld seam position is to expose weld seam, can be worn, and all the other weld seams of middle plate is shielded, even while having compared with galling, be still complete structure.

Detailed description of the invention
As depicted in figs. 1 and 2, the utility model comprises middle plate, base plate 7, shovel riser 8 between the gear riser 4 of middle plate both sides, both sides and middle plate and base plate 7 at base plate 7, is positioned at the ramp plate 9 in shovel riser 8 outsides, and above-mentioned shovel riser 8 be flat board.When manufacture, the utility model adopts smithwelding formula structure, and all parts do not adopt cast article; Simple in structure, to be convenient to manufacture, specific contact pressure is little, wear-resistant.
Middle plate is double-decker; comprise plate 5 and lower plate 6 in work; middle plate is taken interface and is adopted W type structure; can first sacrifice the wearing and tearing of plate in a part; protecting major part to take interface is not worn; because intensity of the present utility model is that the framed structure that relies on gear riser 4, lower plate 6, base plate 7, shovel riser 8 to weld stroke ensures; in actual use, the subregion of base plate 7 and gear riser 4, shovel riser 8 is worn; and the wearing and tearing of plate 5 during these several places wearing and tearing will be starkly lower than and live, therefore intensity of the present utility model does not almost decline.
In work, plate 5 is to be welded in above-mentioned framed structure, need to change time, uses gouge plane to open, and just plate in work 5 can be taken out, and again more renews.
Described ramp plate 9 is high-strength abrasion-proof steel plate.Ramp plate 9 is tracks of slipper of coal producer, generally adopts ZG30SiMn casting to form, and adopts high-strength abrasion-proof steel plate herein, therefore have stronger resistance to abrasion.
Described base plate 7 adopts v-shaped structure, can increase the area of contact of scraper plate and base plate 7, reduces specific pressure, so reduce the wearing and tearing between base plate and scraper plate, reduces go back to coal space.
As shown in Figure 3, weld seam 11 positions are to expose weld seam to the weld seam of middle Board position, can be worn, and all the other weld seams 12 of middle plate are shielded, and middle plate welding seams is protected, even while having compared with galling, be still complete structure.
