Abstract
The utility model relates to the technical field of underground coal mine ultra-thin coal seam mining conveyor tool, specifically a kind of transporting chute ledge.The utility model provides a kind of overall rolled ledge, it is characterized by: ledge medial surface (M) midway location is provided with the section of stretching out, and this section of stretching out is crossing with F, E face, and the β angle of formation is 135 ° ~ 160 °, its length dimension L
1along length under inside < ledge.The utility model is while meeting intermediate channel working strength, optimize welding process, robot automatic welding can be realized, reduce cost of labor, enhance productivity, this mechanism strengthens the intensity of ledge itself simultaneously, the squeese pressure preventing ledge to be subject in conveyer fortune coal process or unbalance stress and cause ledge to be out of shape brisement in hydraulic support pushing-pulling-rack process.
Description
Technical field
The utility model relates to the technical field of underground coal mine ultra-thin coal seam mining conveyor tool, specifically a kind of transporting chute ledge, is applicable to be arranged on the chute of slat conveyer chute, coal plough.
Background technology
At present, the conveyer chute ledge that China's ultra-thin coal seam uses has two large classes: casting ledge and rolled ledge, compare casting ledge, rolled ledge has compact conformation, one-shot forming intensity is higher, outward appearance is clean and tidy, without foundry defect, be out of shape the advantages such as little, make it have obvious advantage in ultra-thin coal seam load transfer device application aspect.The rolled ledge of prior art mostly is again M type, but due to the restriction by ledge height dimension and this body structure of ledge, make its subsequent parts in welding, there is certain inferior position, not easily realize the automation of welding, all adopt human weld, production efficiency is low, cannot reach the cost-effectiveness requirement of production.
Summary of the invention
The purpose of this utility model is to provide a kind of transporting chute ledge, employing section is the rolled structure of " mountain " type, optimize the welding process of chute ledge and middle plate, robot automatic welding can be realized, reduce cost of labor, enhance productivity, and while guarantee ledge intensity, reduce intermediate channel height, to meet the supporting requirement of ultra-thin coal seam fully-mechanized mining working mechanization three machine.
The technical solution of the utility model is: a kind of transporting chute ledge, ledge is overall rolling, it is characterized in that: ledge medial surface (M) midway location is provided with the section of stretching out, and this section of stretching out is crossing with F, E face, the β angle formed is 135 ° ~ 160 °, its length dimension L
1along length under inside < ledge.
Further, the size in the section of the stretching out B face of described ledge medial surface (M) midway location is controlled by β angle and middle plate thickness, and preferred size is L
2be 10 ~ 35mm.
The beneficial effects of the utility model are: adopt section to be " mountain " type structure, be convenient to welding operation, robot automatic welding can be realized, reduce cost of labor, enhance productivity, and rolled ledge compact conformation, effectively reduce intermediate channel height thus reduce complete machine height, meet the requirement that ultra-thin coal seam driving surface is supporting, be conducive to the supporting realization of ultra-thin coal seam fully-mechanized mining equipment, meet the production requirement of fully-mechanized mining working high-yield and high-efficiency.
The utility model is relative to the M type ledge of prior art, compared with traditional ledge, inside ledge, the section of stretching out of middle part optimizes the welding process of intermediate channel, can realize robot automatic welding, reduce cost of labor, enhance productivity, be convenient to batch welding, and ensure that the weld strength of middle plate, make intermediate channel have more reliability, improve the service life of intermediate channel in down-hole, what the section of stretching out outside ledge also helped inblock cast or forging termination inlays welding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the intermediate channel schematic diagram with the utility model assembling.
Fig. 3 is M type ledge structural representation.
Detailed description of the invention
In figure: 1, forge termination, 2, middle plate, 3, rolled ledge, M, ledge medial surface.
A kind of transporting chute ledge as shown in Figure 1, ledge is overall rolling, it is characterized in that: ledge medial surface (M) midway location is provided with the section of stretching out, and this section of stretching out is crossing with F, E face, and the β angle of formation is 135 ° ~ 160 °, its length dimension L
1along length under inside < ledge.
The size in the section of the stretching out B face of described ledge medial surface (M) midway location is controlled by β angle and middle plate thickness, and preferred size is L
2be respectively 10mm, 12mm, 16mm, 20mm, 25mm, 30mm, 35mm.
As shown in Figure 2, slat conveyer chute is primarily of being arranged at the ledge of both sides and being fixedly connected on plate formation between the two, and slat conveyer chute is formed by connecting by the termination be welded on ledge by multiple intermediate channel.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
Claims (2)
1. a transporting chute ledge, ledge is overall rolling, it is characterized in that: ledge medial surface (M) midway location is provided with the section of stretching out, and this section of stretching out is crossing with F, E face respectively, and the β angle of formation is 135 ° ~ 160 °, extension length dimension L
1along length under inside < ledge.
2. a kind of transporting chute ledge as claimed in claim 1, is characterized in that: the size in the section of the stretching out B face of described ledge medial surface (M) midway location is controlled by β angle and middle plate thickness, and preferred size is L
