Abstract

The utility model relates to a scraper conveyor, particularly a double middle plate type middle part groove of scraper conveyer, which comprises a middle plate and a ledges 1 which are respectively welded on both sides of the middle plate, wherein, the middle plate is composed of an upper middle plate 2 and a lower middle plate 3, and the upper middle plate 2 and the lower middle plate do not contact each other. After the utility model is adopted, the integral structure of the middle plate is changed. A single middle plate is changed into the structure of a tank-shaped double middle plate. The integral strength of a middle part groove is increased.

Description

Board-like intermediate channel during slat conveyer is two

Technical field

The utility model relates to slat conveyer, board-like intermediate channel during especially a kind of slat conveyer is two.

Background technology

Slat conveyer is a kind of of Transport Machinery, its application is very extensive, in mining, in the coal mining industry, be a kind of main important machinery especially at delivered downhole coal, intermediate channel then is the important component part of slat conveyer, the stage casing of whole slat conveyer is made of a lot of joint intermediate channel, and at present, intermediate channel mainly comprises ledge and middle plate, two sections ledges have just constituted intermediate channel by middle plate weld together, and wherein middle plate is the wear-resisting steel plate of a thick about 20-40mm normally.

In the underground coal transportation, the whole middle groove, especially wherein middle plate is bearing enormous function power, mainly be the pressure of top coal and the thrust of side supports, under such condition, the junction of middle plate and middle plate and ledge is very easily damaged, in case middle plate torsional deflection or with the fracture of the junction of ledge, then this joint intermediate channel must be changed, yet can only change with the mode of manpower in the down-hole at present, working strength of workers is big, and work efficiency is but not high, also is prone to accidents.

Summary of the invention

For the damage of plate in reducing and middle plate and ledge junction, the utility model proposes a kind of slat conveyer two in board-like intermediate channel.

Board-like intermediate channel during slat conveyer is two, in comprising plate and be welded on respectively in the ledge of plate both sides, middle plate wherein by plate in last with down plate forms, and plate does not contact mutually with following middle plate in going up.

After the board-like intermediate channel, change had taken place in the integral structure of middle plate during employing was two, became the two middle plate structures of box-shaped by an independent middle plate, and the bulk strength of intermediate channel improves greatly.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment

Come the specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, at present in the intermediate channel of generally using, middle plate is an independent plate, in the actual use in down-hole, especially in heavy type, in the use of superduty slat conveyer, because middle plate can't bear enormous function power, himself very easily is out of shape, and the junction of itself and ledge is also very easily damaged, as shown in Figure 1, plate and be welded on the ledge 1 of middle plate both sides respectively during intermediate channel comprises in the utility model, plate was changed into by plate in last 2 and down middle plate 3 by an independent plate and constituting jointly during its pin improvements over the prior art were, two blocks of middle plates one on the other, do not contact mutually, respectively with ledge 1 weld together, plate 2 is mainly born the effect of former middle plate in wherein going up, manufacturing materials is also identical with former middle plate, and plate 3 is mainly used in the Joint strenght of strengthening with ledge down, generally be difficult for being worn, can adopt common iron or other can satisfy the material of requirement of strength, clearly, the variable thickness phasing of plate 2 and down middle plate 3 together upward, but should leave suitable gap between two blocks of middle plates, guarantee to constitute case structure with higher-strength, in addition, two blocks of middle plates are parallel and obviously have best intensity with the ledge 1 vertical case structure that constitutes respectively, in the actual product transformation process, can in former, below the plate plate in another piece and ledge 1 weld together be got final product, if can guarantee that two blocks of middle plates are parallel and vertical then for best with ledge 1 respectively.

Claims

1, slat conveyer two in board-like intermediate channel, in comprising plate and be welded on respectively in the ledge of plate both sides, it is characterized in that: in described plate by plate (2) in last and down plate (3) forms, and go up middle plate (2) and do not contact mutually with following middle plate (3).

2, slat conveyer as claimed in claim 1 two in board-like intermediate channel, it is characterized in that: plate (2) and down middle plate (3) are parallel to each other in described the going up.
