The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, the present embodiment open cast mine feedway, comprises pit material conveyor 1, crusher 2, material output machine 3, material elevator 4 and ground material conveyor 5, and each several part is connected setting in turn along mass transport direction.Pit material conveyor 1 is parallel to the production face in pit, and for horizontal feed, and its end is connected in the material input port of crusher 2, and the material delivery port of crusher 2 is connected in material output machine 3.Material elevator 4 comprises that lower horizontal 4-1, intermediate, inclined raising section 4-2 and upper level section 4-3 form, and lower horizontal 4-1 is connected with material output machine 3.
Concrete, the concrete use procedure of the present embodiment open cast mine feedway is: the mineral of having an opencast mining of out by monobucket truck transport to the pit material conveyor 1 in pit, then enter and in crusher 2, carry out bulky grain fragmentation, be crushed to diameter or width and be 200～300mm compared with granule, to facilitate conveying, prevent from because deadweight scatters, causing danger on the material elevator 4 of bulky grain mineral aggregate below simultaneously; After mineral aggregate fragmentation, by material output machine 3, be delivered to the lower horizontal 4-1 of material elevator 4, then through intermediate, inclined raising section 4-2, be promoted to ground upper level section 4-3, then enter ground material conveyor 5 and carry.
For ease of material, from 3 outputs of material output machine, enter smoothly material elevator 4, material output machine 3 is by the setting that is inclined upwardly of its input end to mouth, its inclination angle beta is 15～30 °, the belt pulley 3-1 of its mouth be positioned at material elevator 4 input end belt pulley 4-4 directly over.
Material elevator 4 adopts rubber belt conveyor, and its inclination alpha is 75～90 °, and hoisting depth H is 200～300m, can realize high spud angle, long distance conveying.
For improving conveying efficiency, the present embodiment open cast mine feedway also comprises storage tank 6, and the input end of pit material conveyor 1 is positioned at storage tank 6, is connected with storage tank 6.By self lighting type monobucket truck, transport continuously also discharging and, to the interior interim storage of storage tank 6, can just can meet operating needs by the less monobucket truck of usage quantity, saved traffic cost, improved the operating efficiency of the present embodiment open cast mine feedway simultaneously.
Based on technique scheme, optional, for realizing the high spud angle of material elevator 4, long distance conveying, the load-transfer device of material elevator 4 is that steel rope composite elastic body high-tenacity promotes load-transfer device.With reference to Fig. 2, the load-transfer device of material elevator 4 comprises base band 4-4, rib 4-6 and cross wall 4-7 are set on base band 4-4, base band 4-4 comprises covering glue layer 4-4-1 and is coated on longitudinal steel wire rope casing play 4-4-2 and the lateral stiffness strengthening course 4-4-3 in covering glue layer 4-4-1, wherein, longitudinal steel wire rope casing play 4-4-2 is two-layer, between two longitudinal steel wire rope casing play 4-4-2, be above-mentioned lateral stiffness strengthening course 4-4-3, distance t between adjacent wires rope in each longitudinal steel wire rope casing play 4-4-2 is 2～6mm, make each steel rope close-packed arrays, can improve the strength property of load-transfer device, the diameter d of steel rope meets steel wire rope used for conveyer belt national standard.
Certainly, longitudinal steel wire rope casing play 4-4-2 also can be set to two-layer more than, according to actual job situation, determine.By two-layer or two-layer above longitudinal steel wire rope casing play 4-4-2 is set, lateral stiffness strengthening course 4-4-3 is between adjacent longitudinal steel wire rope casing play 1-2, form steel rope composite elastic body (steel cord composite, be abbreviated as STC), have quite high strength property, the lifting load-transfer device therefore with this structure steel rope is called steel rope composite elastic body high-tenacity and promotes load-transfer device.
For further strengthening the rigidity of the load-transfer device of material elevator 4, in each longitudinal steel wire rope casing play 4-4-2, the longitudinal steel wire rope casing play 4-4-2 of the superiors top is also provided with one deck lateral stiffness strengthening course 4-4-3.
The position of corresponding each cross wall 4-7 of upper surface of base band 4-4 has groove 4-4-4, the bottom of each cross wall 4-7 is positioned at its each self-corresponding groove 4-4-4, the longitudinal steel wire rope casing play 4-4-2 of the superiors and the lateral stiffness strengthening course 4-4-3 of top thereof separate the both sides at groove 4-4-4, and cross wall 4-7 is except its underpart is connected with rib 4-6 bolt, and its both sides, top are also connected by bolt 4-8 with the rib 4-2 of its respective side.
Particularly, groove 4-4-4 can be formed by the thickness that suitably increases cross wall 4-7 both sides base band 4-4, and the thickness L of base band 1 is 100～300mm herein, the degree of depth h of groove 4-4-4, and thickness value within the scope of 5-15mm of the base band 1 that increased is advisable.The bottom of cross wall 4-7 embeds in groove 1-4, and its both sides, top are connected with rib 4-4 bolt, thereby make herein load-transfer device form keel structure, thereby greatly strengthened cross wall 4-7 and base band 4-4, and the Joint strenght of rib 4-6, prevent that junction from tearing.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
