SU1754903A1 - Loading device of tunnel shield conveyor - Google Patents

Description

The invention relates to the field of mining, namely to devices designed to load trucks with rock from the conveyor of the tunnel shield.

The purpose of the invention is to improve the performance of loading rocks in the trolley.

Figure 1 shows the boot device conveyor tunneling shield, side view; Fig. 2 is a view A in Fig. 1 (the casing shield is conventionally not shown); on fig.Z - view B in figure 2; figure 4 - boot device with a movable bottom drummer.

The loading device 1 of the conveyor 2 of the tunnel shield 3 consists of a body 4 in which a damper is placed, made in the form of two buckets 5, each with side walls 6 and an inclined bottom 7. Each bucket 5 is connected by means of hinges 8 and 9 and turning levers 10 and 11 with a hinge 12 of the stem 13 of the power cylinder 14. The hinge 12 of the stem 13 is installed in the guide groove 15 of the housing 4. The buckets 5 are equipped with guides 16 on whose shelves 17 are installed in the initial position (position I) with the possibility of translational movement to the gate position 18. Shibera 18 in filled with a pointed edge 19 and with an end part 20. The guides 16 are provided with brakes made in the form of spring sheets 21 mounted over the guides 16. Adjusting screws 22 are mounted on the body 4 to adjust the force of displacement of the gates 18 23 gates 18. The loading device is located in the tunnel shield 3 behind the conveyor 2 above the trolleys 24 installed on the track 25.

Each bucket 5 can be equipped with a movable bottom drummer 26 with a restrictive shoulder 27 mounted in the bucket hole 28 with the ability to interact with a return pusher and with a vertical plate 29 attached to the back side of the inclined bucket 7.

The boot device operates as follows.

The rock developed by the executive body (not shown) of the tunneling shield along the conveyor 2 is continuously fed into the loading device. The rod 13 of the power cylinder 14 is extended and the gate of the ladle 5, installed in the initial position in position 1, are interconnected.

The developed rock is poured into a container formed by inclined bottoms 7 and side walls 6 connected by a ladle 5. After the empty trolley 24 is fed under the charging device, the rod 13 from the Suture 14 is retracted, moving the hinge 12 in the guide groove 15, and turning levers 10 and 11 and the buckets 5 are opened. The breed from the loading device and from the conveyor is reloaded into the trolley 24. After loading the trolley, the rod 13 of the hydraulic cylinder 14 extends, moving the hinge 12 of the rotation arms 10 and 11 and closing the buckets 5 along the guide groove 15, and the rock is poured into buckets 5.

When a large piece of rock gets between the pointed edges 19 of the gates 18, the latter along the shelves 17 move to position II or any intermediate position determined by the size of the piece of rock. Schieber 18 with its sharp edges 19 hold a large piece of rock. The rest of the gate 18 remains in position I until the buckets 5 are closed and the connection of the pointed edges 19 of the gate 18. The rock coming from the conveyor 2 does not slip into the carriage 24 between the closed

gates 18 and between gates 18, holding a large piece of rock. After replacing (pulling) the carriage 24, the rod 13 of the power cylinder 14 is retracted and moves the hinge 12 of the rotation arms 11 and opens the buckets 5. At the same time, the scraper 18, which is in position 11, abuts the end part 20 into the return pushers 23 and returns to its original position (in position I). Then the cycle is repeated.

To prevent breaking of pieces of rock that fell between the gates 18, adjusting screws 22 are used to control the forces of movement of the movable gates 18 in the guides 16.
