Abstract
The utility model discloses a kind of scraper conveyor middle groove, comprise middle plate and ledge, described ledge is arranged at middle plate both sides, and described ledge medial surface is set to arcwall face; Described middle plate comprises wearing layer, bed course and bottom composite integrated structure from top to bottom; In this complex, the dual-side of plate mates Butt sealing with convex-concave between ledge and fixes.It is larger that the utility model cambered surface ledge makes scraper plate and ledge medial surface direct contact surface amass, and contact when slat conveyer level or vertical curve is little, thus reduces friction drag, reduces power consumption, extends the life-span.
Description
Technical field
The utility model relates to scrapper conveyor parts technical field of improvement, particularly relates to a kind of scraper conveyor middle groove improvement opportunity.
Background technology
Slat conveyer is the main load transfer device of coal wall, for meeting the Production requirement of the intensive mine of high-yield and high-efficiency, since the eighties in 20th century, domestic and international slat conveyer is constantly to large conveying quantity, long haul distance, high-power, long life and high reliability future development.Correspondingly, the research and development of High Performance slat conveyer component are had higher requirement.The intermediate channel of slat conveyer is the bearing part of material, bears the severe friction of coal, scraper plate and chain in operational process, is the maximum parts of use amount and consumption.The quality of intermediate channel accounts for more than 70% of slat conveyer total mass, the inefficacy of slat conveyer, is caused also by the undue wear of intermediate channel or fracture, so the service life of intermediate channel is the important indicator weighing machine life.Intermediate channel except fortune coal except, also to bear the operating load of coalcutter, push away, draw side force and the longitudinal force of hydraulic support, coarse coal, rock stuck in groove time extruding, impulsive force etc. because intermediate channel is very easily damaged.
Utility model content
The utility model, for problems of the prior art and deficiency, provides a kind of scraper conveyor middle groove.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of scraper conveyor middle groove, comprises middle plate and ledge, and described ledge is arranged at middle plate both sides, and described ledge medial surface is set to arcwall face; Described middle plate comprises wearing layer, bed course and bottom composite integrated structure from top to bottom; In this complex, the dual-side of plate mates Butt sealing with convex-concave between ledge and fixes.
The dual-side of described wearing layer is provided with convex platform, mates dock with ledge; Bottom both sides are provided with lower bulge, mate dock with ledge; Convex platform and lower bulge are interspersed, and are fixed together respectively by bolt and ledge.The wearing layer of described middle plate, bed course and bottom are connected and fixed by bonding or welding or riveted joint or bolt.
When described middle plate surface is because of damages such as distortion, wearing and tearing, adopt carbonized tungsten Electric Welding Buttering Technique renovation technique, after repairing, wearing course mean thickness is no less than 6mm, and the intermediate channel after reparation reaches the dimensional characteristic of design of dispatching from the factory.
The utility model has the advantages that:
1, cambered surface ledge makes scraper plate and ledge medial surface direct contact surface amass more greatly, and contact when slat conveyer level or vertical curve is little, thus reduces friction drag, reduces power consumption, extends the life-span;
2, after damaging, employing special metals cladding welding machine is to contact abration position surface cladding, and hardness HRC54-65 degree after repairing, fusion penetration 1-10mm improves 2-3 doubly service life, and its cost performance is raw-material 2-4 times.

Fig. 2 is the end construction schematic diagram of Fig. 1;
Fig. 3 is the partial assembled structural representation of Fig. 1.
In accompanying drawing, 1-middle plate; 2-ledge; 3-arcwall face; 4-convex platform; 5-lower bulge; 6-bolt; 7-fixed orifice; 11-wearing layer; 12-bed course; 13-bottom.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2, scraper conveyor middle groove comprises middle plate 1 and ledge 2, and described ledge 2 is arranged at middle plate 1 both sides, and described ledge 2 medial surface is set to arcwall face 3.
See Fig. 3, middle plate 1 comprises wearing layer 11, bed course 12 and bottom 13 composite integrated structure from top to bottom; In this complex, the dual-side of plate 1 mates Butt sealing with convex-concave between ledge 2 and fixes.
In Fig. 3, the dual-side of wearing layer 11 is provided with convex platform 4, mates dock with ledge 2; Bottom 13 both sides are provided with lower bulge 5, mate dock with ledge 2; Convex platform 4 and lower bulge 5 are interspersed, and are fixed together respectively by bolt 6 and ledge 2.The wearing layer 11 of described middle plate 1, bed course 12 and bottom 13 are connected and fixed by bonding or welding or riveted joint or bolt.
When central plate 1 surface is because of damages such as distortion, wearing and tearing, adopt carbonized tungsten Electric Welding Buttering Technique renovation technique, after repairing, wearing course mean thickness is no less than 6mm, and the intermediate channel after reparation reaches the dimensional characteristic of dispatching from the factory and designing.
It is last it is noted that above-described embodiment is only for the utility model example is clearly described; and the restriction not to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all embodiments, and thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
