Abstract
The utility model discloses a heavy grade loaderdigger antiskid track, it contains the track bottom plate, the interval is provided with splayed or lambdoid shoe thorn board on the surface of track bottom plate, and is adjacent it is provided with the gusset to carry out between the thorn board, carry out highly being greater than of thorn board the height of gusset. The both sides of track bottom plate are provided with the connecting plate respectively, be provided with the shaft hole on the connecting plate, still be provided with the perforating hole on the track bottom plate. The utility model discloses grip -pad structure to the loaderdigger track is improved, and the grip -pad after the improvement adopts two " eight " word structures to increasing the shoe thorn of grip -pad, carrying out the thorn with the grip -pad and increase to 30mm, increase crawler -type loaderdigger is to the adaptability in big inclination tunnel, and is anti -skidding effectual.
Description
Technical field:
The utility model relates to the system that a kind of mine development end spoil is discharged, and particularly relates to a kind of heavy grade backhoe loader skid track.
Background technology:
At present, tunnelling machine gradient generally in ± 16 °, roadway gradient is super go beyond the scope time, conventional method is big gun pick, and not only danger is very high in big gun pick operation, and development machine stops operation, big gun pick is carried out to driving surface, the waste plenty of time, affects digging efficiency.Especially some special operation condition (as when face is below bridge, building) forbids again big gun to be dug, tunnel digging angle can only be changed in this case, process like this adds unnecessary work capacity on the one hand, decrease the exploited length in tunnel simultaneously, cause the waste of a large amount of coal resources.Therefore, be necessary to design a kind of heavy grade backhoe loader that can be operated in the larger tunnel of the gradient, to adapt to the service conditions in high spud angle tunnel.
The mining equiment such as backhoe loader, development machine used in current China tunnel, many employing broad track forms, to reduce specific pressure over the ground, strengthen hill climbing ability.For adopted crawler belt, its maximum grade that longitudinally works is
, when the strong drying of base plate, hill climbing ability increases slightly to some extent.This hill climbing ability of backhoe loader can adapt to the down-hole coal bed condition of China's wide geographic area more widely, but indivedual complicated geology mine, seam inclination exceedes
time, common backhoe loader is difficult to meet its working environment.
In heavy grade tunnel, some problem following when backhoe loader works in tunnel, will be run into:
(1) because inclination angle, tunnel has exceeded the range of use of backhoe loader itself, the sliding force of fuselage increases, and for descending tunnel, the increase at inclination angle will make the center of gravity of fuselage move forward, make backhoe loader normally climb or to retreat, moreover need to stop when stopping do not live car and continue to glide.
(2), time for employing belt-conveying, due to the increase at inclination angle, likely can exceed the angle of repose of material itself, material phenomenon may be rolled when the time comes.
(3) for Loose floor, machine may sink, skid.
For these situations occurred, not only can have influence on the production efficiency in colliery, cause the fault of machine, and the life security of staff in tunnel can be had influence on.Therefore be necessary that research and development heavy grade backhoe loader is to adapt to the work operating needs in heavy grade tunnel.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, intensity is high, hill climbing ability is strong and the heavy grade backhoe loader skid track easily implemented.
The technical solution of the utility model is:
A kind of heavy grade backhoe loader skid track, containing crawler belt base plate, the outside face of described crawler belt base plate is arranged at intervals with splayed or lambdoid grouser plate, is provided with gusset between adjacent described grouser plate, the height of described grouser plate is greater than the height of described gusset.
The both sides of described crawler belt base plate are respectively arranged with connecting panel, and described connecting panel is provided with axis hole, and described crawler belt base plate is also provided with through hole.Described grouser plate and described crawler belt base plate are welded and fixed, and described gusset and described grouser plate and crawler belt base plate are all welded and fixed.
The beneficial effects of the utility model are:
1, the utility model improves for the track plate structure of backhoe loader crawler belt, caterpillar block after improvement adopts two " eight " word structure, and the grouser of caterpillar block is increased, caterpillar block grouser is increased to 30mm, increase the adaptive capacity of caterpillar type loader digger for high spud angle tunnel, good antiskid effect.
2, the utility model crawler belt base plate is also provided with connecting panel, through hole and axis hole, be convenient to the quick connection of adjacent track base plate, efficiency is high.
3, the utility model is reasonable in design, intensity is high, hill climbing ability by force and easily implement, it is applied widely, is easy to promotion and implementation, and economic benefit is obvious.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of heavy grade backhoe loader skid track.
Detailed description of the invention:
Embodiment: see in Fig. 1, figure, 15-crawler belt base plate, 16-grouser plate, 17-gusset, 18-connecting panel, 19-through hole, 20-axis hole.
Heavy grade backhoe loader skid track contains crawler belt base plate 15, wherein: the outside face of crawler belt base plate 15 is arranged at intervals with splayed or lambdoid grouser plate 16, be provided with gusset 17 between adjacent grouser plate 16, the height of grouser plate 16 is greater than the height of gusset 17.
The both sides of crawler belt base plate 15 are respectively arranged with connecting panel 18, connecting panel 18 are provided with axis hole 20, and crawler belt base plate 15 is also provided with through hole 19.Grouser plate 15 and crawler belt base plate 15 are welded and fixed, and gusset 17 is all welded and fixed with grouser plate 16 and crawler belt base plate 15.
The utility model improves for the track plate structure of backhoe loader crawler belt, caterpillar block after improvement adopts two " eight " word structure, and the grouser of caterpillar block is increased, caterpillar block grouser is increased to 30mm, increase the adaptive capacity of caterpillar type loader digger for high spud angle tunnel, good antiskid effect.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
