Abstract
The utility model relates to a shoveling aid type middle groove of a scraper conveyor, which comprises a shovel ledge, a baffle ledge, a middle plate and a rack rail seat. Stiffeners are arranged between the male head and the female head of the outer side of the shovel ledge; and the outer sides of the stiffeners are in arc shape. The utility model is characterized in that an arc-shaped steel plate is arranged between the male head and the female head of the outer side of the shovel ledge and fits with the outer sides of the stiffeners; the arc-shaped steel plate is welded on the stiffeners in an adhesive way; the outer side of the bottom end of the arc-shaped steel plate is flush with the outer side of the top part of the shovel tip of the shovel ledge. The utility model can dispense the resistance of the coal layer by the shovel ledge so that the coal layer can enter the middle plate of the middle groove more easily, thereby reducing the force on the pushing lug and the whole groove body, decreasing the deadly damage such as the cracking and deformation of the groove body and prolonging the service life of the middle groove.
Description
Technical field
The utility model relates to a kind of intermediate channel of slat conveyer.
Background technology
The intermediate channel of slat conveyer generally has shovel board ledge, baffle plate ledge, middle plate etc.Be provided with several reinforced ribs between the male in the described shovel board ledge outside and the female.Hydraulic support withstands the passing ear of baffle plate ledge one side during intermediate channel work, intermediate channel side travel, shovel board ledge enter in the coal seam of cutting, and squeeze mutually with the coal seam, the coal seam come-up enters into chute, and the scraper chain that actuating unit drives is scraped and is being with coal continuously to transport to transfer post.Intermediate channel weight is very big, and also quite big with the friction drag in coal seam, the coal seam is not easy to enter on the intermediate channel plate, passes the stressed increase of ear and even whole cell body, causes cell body fatal damages such as ruptural deformation to occur.CN200964294Y discloses a kind of The middle pan of scraper conveyor ramp plate ledge, is characterized in that described reinforced rib is positioned under the tangent line of ramp plate ledge outer vertical knuckle and vertical surface topmost.It is reduced to reinforced rib topmost under the point of contact (line) of plane on the ledge and vertical surface knuckle and vertical surface.CN2312914Y discloses a kind of slat conveyer fixed frame slot type interlude chute of going up alive, it is made up of shovel board ledge, baffle plate ledge, down middle plate, gusset and the groove of going up alive, by down middle plate and gusset shovel board ledge and baffle plate ledge are linked together, live by assembly opening and knock hole and go up the top that groove is connected shovel board ledge and baffle plate ledge.These technology obtain disperseing not provide the technical scheme of directiveness for the resistance that how to make the shovel board ledge be subjected to the coal seam.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, what a kind of slat conveyer was provided helps the shovel intermediate channel, the resistance that makes the shovel board ledge be subjected to the coal seam obtains disperseing, the coal seam is easier to be entered on the intermediate channel plate, and then reduce and pass the stressed of ear and even whole cell body, reduce fatal damages such as cell body ruptural deformation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of slat conveyer help the shovel intermediate channel, has the shovel board ledge, the baffle plate ledge, middle plate, the rack rails seat, be provided with several reinforced ribs between the male in the described shovel board ledge outside and the female, the lateral surface of these several reinforced ribs is circular-arc, its technical scheme is to be provided with circular-arc steel plate between the male in the above-mentioned shovel board ledge outside and the female, the lateral surface of described circular-arc steel plate and these several reinforced ribs matches, circular-arc steel plate pastes and is welded on these several reinforced ribs, and the bottom lateral surface of described circular-arc steel plate is mutually neat with the spear top outside of shovel board ledge.
The utility model is to be provided with circular-arc steel plate between the male in the above-mentioned shovel board ledge outside and the female, the lateral surface of described circular-arc steel plate and these several reinforced ribs matches, circular-arc steel plate pastes and is welded on these several reinforced ribs, and the bottom lateral surface of described circular-arc steel plate is mutually neat with the spear top outside of shovel board ledge.Like this, between shovel board ledge side male and female, paste weldering circular-arc steel plate (shovel gusset), when hydraulic support pushes away intermediate channel when coal face moves, the relative motion of coal seam and shovel board ledge changes into along circular-arc steel plate and sliding, changed original form that vertically pushes away coal, the big base plate of shovel board ledge makes the stable direction of maintenance in the moving process, make it stressed evenly with circular-arc steel plate cooperation, can not produce and float and sink, make intermediate channel stressed rationally, make its resistance that is subjected to the coal seam obtain disperseing, resistance reduces, and the coal seam is easier to be entered on the intermediate channel plate, and has reduced and passed the stressed of ear and even whole cell body, actv. has reduced to have reduced fatal damages such as cell body ruptural deformation to passing the wearing and tearing of ear.Can improve the service life of intermediate channel.The utility model is simple in structure, and cost is low, and result of use is good, especially to the welding intermediate channel, can effectively prevent common weld cracking problem.It can be saved time, thereby has improved the efficient of carry coal.

Fig. 2 is along the cutaway view of A-A line among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utlity model has rack rails seat 1, shovel board ledge 2, baffle plate 3, circular-arc steel plate (shovel gusset) 4, middle plate 5, baffle plate ledge 6, passing ear 7.Be provided with several reinforced ribs 21 between the male in described shovel board ledge 2 outsides and the female, the lateral surface of these several reinforced ribs 21 is circular-arc.The quantity of reinforced rib can be 1～5, and the quantity of reinforced rib is 3 in the present embodiment.Be provided with circular-arc steel plate 4 between the male in above-mentioned shovel board ledge 2 outsides and the female, described circular-arc steel plate 4 matches with the lateral surface of these several reinforced ribs 21, circular-arc steel plate 4 pastes and is welded on these several reinforced ribs 21, and the bottom lateral surface of described circular-arc steel plate 4 is mutually neat with the spear top outside 22 of shovel board ledge 2.Circular-arc steel plate 4 adopts the 16Mn steel plate, and resistance to abrasion is good, the intensity height.
