Detailed Description

The technical scheme of the utility model is explained in detail below with the attached drawings:

referring to fig. 1 and 2, a blind shaft belt relay transport system comprises a plurality of belt conveyors 1 arranged in a stepped tunnel; the stepped roadway comprises a plurality of roadway sections which are sequentially connected and communicated, and the adjacent roadway sections have height difference; the belt conveyors 1 correspond to the roadway sections one by one, and one belt conveyor 1 is arranged in each section of roadway; all belt conveyors 1 are transported in the same direction from a higher roadway section to a lower roadway section.

For the mine case, the original TD75-1200 belt conveyor 1 located under the No. 1 and No. 2 drop shafts in the middle section of the-990 section is firstly extended to 104 meters from the original 87 meters, and then a new TD75-1200 belt conveyor 1 located under the No. 3 drop shaft is installed, wherein the length of the conveyor is 36 meters. During transformation, the belt, the rear roller, the belt adjusting device and the like need to be detached from the rack, then the lengthened rack is installed, the lengthened belt is replaced, and the belt, the added roller and the like are installed on the rack.

For the adjacent belt conveyor 1: the discharging end of the belt conveyor 1 arranged on the higher roadway section is positioned above the feeding end of the belt conveyor 1 arranged on the lower roadway section; a chute 3 for guiding materials is also arranged at the discharging end of the belt conveyer 1 positioned on the higher roadway section; so that ore on the belt of the previous conveyor can fall down the chute 3 onto the belt of the next conveyor. Meanwhile, the frame part at the discharging end of the belt conveyor 1 on the higher roadway section is installed on the support 4, and the support 4 is installed on the ground of the lower roadway section to support the overhanging part of the belt conveyor 1.

obviously, the above-mentioned method is applicable to three or more stepped roadways.

Still install backplate 2 in the frame that belt conveyor 1 connects material station department, backplate 2 is located the both sides of belt, rolls the belt outside after preventing that the ore from falling down.

As shown in fig. 3, the chute 3 is made of a steel plate and comprises a horizontal channel 3-1 and a vertical channel 3-2, the blanking end of the belt conveyor 1 is positioned at the inlet of the rear end of the horizontal channel 3-1, and the upper end of the vertical channel 3-2 is communicated with the front end of the horizontal channel 3-1. The ore enters the horizontal channel 3-1 and then the vertical channel 3-2, and then falls onto the next belt conveyor 1.

the lower half part of the rear side wall plate of the vertical channel 3-2 is a detachable inclined plate 3-4 with the lower end inclined to the front side. The purpose of the inclined arrangement is to enable ores to fall onto the belt in a rolling mode instead of falling vertically, so that the ores are buffered to a certain extent and prevented from rebounding to the outer side of the belt after falling. The sloping plates 3-4 are therefore the most vulnerable parts in contact with the ore and need to be replaced frequently.

Referring to fig. 3 and 4, a hanging ring is arranged at the top end of an inclined plate 3-4, a hook 3-3 matched with the hanging ring is arranged on the rear side surface of the upper half part of the rear side wall plate of the vertical channel 3-2, and the left side edge and the right side edge of the inclined plate 3-4 are in close contact with the side plate of the vertical channel 3-2 under the action of a fastening device 3-5.

The materials of the wear-resistant blocks 3-5-4 and the wedge blocks 3-5-2 are all 40Cr, and the surfaces are subjected to high-frequency quenching to improve the wear resistance.

Furthermore, in order to ensure that the wedge block 3-5-2 is stably installed, a set screw 3-5-5 is further installed on the fixed seat 3-5-1, and the tail end of the set screw 3-5-5 is located in the rectangular through hole and used for fixing the wedge block 3-5-2.

When the inclined plates 3-4 need to be replaced, the fastening devices 3-5 are firstly opened, and the method comprises the following steps: the set screw 3-5-5 is loosened, then the wedge 3-5-2 is taken out, and the pressing plate 3-5-3 is rotated to be opened. After all the pressing plates 3-5-3 are opened, the inclined plate 3-4 is detached. Then, hanging a new inclined plate 3-4 on the hook 3-3, leaning the inclined plate 3-4 against a side plate of the chute 3, closing the pressing plate 3-5-3, then tightly pushing the pressing plate 3-5-3 by using the wedge block 3-5-2, and finally fastening the set screw 3-5-5, wherein the wedge block 3-5-2 can not be loosened even if the inclined plate 3-4 is severely vibrated, and sequentially completing the pressing of all the pressing plates 3-5-3 according to the steps.

The hooks 3-3 and the hanging rings are used for positioning the inclined plate 3-4, so that the side edge of the inclined plate 3-4 can be quickly aligned and attached to the side plate of the chute 3.

The fastening devices 3-5 are required to be arranged on the left and right sides of the chute 3, and at least two groups are arranged on each side. The folding edges can be added to the contact part of the side wall plate of the chute 3 and the inclined plate 3-4, so that the contact area is increased, and the installation is convenient.

after the project is finished, the newly-built orepass at the 990 middle section can be smoothly put into use, the deep ore/rubble can directly enter the 930 rail-bound transportation system and is not transported to the 830 orepass along the slope, the transportation distance of the slope is greatly reduced, and the operation cost of trackless equipment and the oil consumption are reduced.
