Description

Technical Field

[0001] This utility model relates to a distribution system for improving the efficiency of slag chute discharge in slag chute wells, and belongs to the field of well construction technology. Background Technology

[0002] During the excavation of the water conveyance inclined shaft of the reservoir (Hubei Dawu Pumped Storage Power Station), a chute well needs to be formed by using a reverse drilling rig to enlarge the borehole based on the construction pilot tunnel. During the reverse drilling process in the rock strata, the efficiency of chute discharge must be ensured.

[0003] The current reverse drilling rig construction chute technology (see Chinese Patent Publication No. CN112012751B) involves the chute being discharged downwards by its own weight and accumulating at the bottom of the chute in the horizontal tunnel. When there is too much chute, the top of the cone-shaped chute accumulation will block the bottom of the chute, affecting the efficiency of chute discharge downwards into the horizontal tunnel. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a distribution system for improving the slag discharge efficiency of slag chutes.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a distribution system for improving the efficiency of slag chutes in slag chutes, comprising:

[0007] Slag chute;

[0008] The slag chute has a lower horizontal tunnel at the bottom and an upper horizontal tunnel at the top.

[0009] A reverse drilling rig is installed in the upper flat tunnel at the top of the slag chute via a mounting base. The reverse drilling rig has a reverse drilling rod. The reverse drilling rod is located inside the slag chute, and a rotary cutting head for cutting rock strata is installed at the end of the reverse drilling rod.

[0010] There is a slag accumulation in the lower horizontal tunnel located at the bottom of the slag chute.

[0011] The lower horizontal tunnel, located in the upper part of the slag chute, has an arm plate on its inner wall. One end of the arm plate is rotatably hinged to the inner wall of the lower horizontal tunnel, and a motor is installed at the other end of the arm plate. A slag hopper is fixed on the output end of the motor. A telescopic rod is hinged to the middle of the arm plate and is rotatably installed on the inner wall of the lower horizontal tunnel.

[0012] Loaders and mining trucks are located in the lower tunnel in front of the slag chute.

[0013] The beneficial effects of this utility model are as follows: the telescopic rod extends and retracts, causing the slag bucket on the arm plate to swing. The slag bucket is driven by a motor to rotate and pull the slag in the top area of ​​the slag pile downward into the horizontal tunnel. This solves the problem that the top of the slag pile, which is in the form of a cone, will block the bottom of the slag chute, thus improving the efficiency of slag chute chutes downward into the horizontal tunnel.

Detailed Implementation

[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0017] like Figure 1 As shown.

[0018] This application discloses a distribution system for improving the efficiency of slag chutes in slag chutes, comprising:

[0019] A reverse drill rod 21 is installed inside the chute 1. The reverse drill rod 21 is a component of the reverse drill rig 2, and a rotating cutting head 22 for cutting rock strata is installed at the end of the reverse drill rod 21. The reverse drill rig 2 is installed in the upper flat tunnel 4 space at the top of the chute 1.

[0020] The bottom of the slag chute 1 is a lower horizontal tunnel 3. After the inner wall of the slag chute 1 is later blasted with explosives, the inner lining wall is constructed to form a water conveyance inclined shaft. The water conveyance inclined shaft connects the upper horizontal tunnel 4 and the lower horizontal tunnel 3.

[0021] There is a slag accumulation body 5 inside the lower horizontal tunnel 3 located at the bottom of the slag chute 1.

[0022] An arm plate 8 is located on the inner wall of the lower horizontal tunnel 3 in the upper part of the slag chute 5. One end of the arm plate 8 is rotatably hinged to the inner wall of the lower horizontal tunnel 3 via a hinge shaft, and a motor 9 is installed on the other end of the arm plate 8. A slag scooping bucket 91 is fixed on the rotating output end of the motor 9. A telescopic rod 81 is hinged to the middle of the arm plate 8. The telescopic rod 81 is rotatably installed on the inner wall of the lower horizontal tunnel 3 via a hinge shaft. The extension and retraction of the telescopic rod 81 causes the slag scooping bucket 91 on the arm plate 8 to swing. The slag scooping bucket 91 is driven by the motor 9 to rotate and scrape the slag in the top area of ​​the slag chute 5 downward into the lower horizontal tunnel 3. This solves the problem that the top of the slag, which is in the form of a cone, will block the bottom of the slag chute, and improves the efficiency of slag chute scooping downward into the lower horizontal tunnel.

[0023] Inside the lower tunnel 3 on the front side of the slag chute 5, there is a loader 6 and a mining truck 7. The loader 6 loads the slag at the bottom of the front side of the slag chute 5 and dumps it into the mining truck 7. The mining truck 7 transports the slag from the lower tunnel 3 to the outside.

[0024] The reverse drilling rig 2 is installed in the upper flat tunnel 4 space at the top of the slag chute 1 via the mounting base 23.
