Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering, and relates to a high-efficiency transportation device for a track-mounted inclined shaft, and in particular to a high-efficiency mucking construction device for a track-mounted inclined shaft with a large slope in a water conveyance tunnel. Background Art

[0002] The water conveyance tunnel is located in the laterite soft rock stratum, and its groundwater level is relatively high. In order to ensure the progress of tunnel construction, auxiliary caverns such as inclined shafts and branch tunnels are often added as the entrances and exits of the tunnel, and drainage is carried out through the inclined shaft to lower the groundwater level to ensure the safety of tunnel construction. Due to the limitations of the depth of the water conveyance tunnel, topography, geology, investment and other conditions, the inclined shaft often has a steep slope and a long distance, and is not suitable for automobile transportation. It is necessary to adopt equipment and solutions suitable for large-slope long inclined shaft rail transportation. Inclined shaft rail transportation needs to undertake the heavy tasks of mucking, feeding (rebar, concrete, etc.), and pedestrians. Most of the currently used rail transportation methods have the disadvantages of slow transportation speed, low construction efficiency, and increased engineering construction costs. Summary of the invention

[0003] In order to solve the shortcomings of the background technology, the present invention provides a high-efficiency mucking construction device for a large-slope rail-mounted inclined shaft of a water conveyance tunnel, which can improve transportation efficiency and reduce labor costs.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A high-efficiency mucking construction device for a steep-slope rail-mounted inclined shaft of a water conveyance tunnel comprises a slope plank road, a curved track, a sheave, a wire rope, a sheave frame, a hoist, a control console, a side-discharging mine car, a first induction device, a mucking bin and a second induction device, wherein:

[0006] The slope plank road is arranged at the branch cave entrance, and a curved track is provided on the slope plank road;

[0007] A sky sheave is arranged on the upper part of the curved track, and the sky sheave is supported by a sky sheave frame;

[0011] The signals of the first sensing device and the second sensing device are aggregated to the console.

[0012] A construction method of the above-mentioned high-efficiency mucking construction device for a large-slope rail-mounted inclined shaft of a water conveyance tunnel comprises the following steps:

[0013] Step 1: The side-unloading mine car is transported from the deep part of the inclined shaft to the branch tunnel through the curved track laid on the slope plank road under the joint action of the hoist, the sheave and the wire rope;

[0014] Step 2: When the side-dumping mining car is transported to the first sensing device in the middle of the curved track, the first sensing device generates an electrical signal and sends it to the control console;

[0015] Step 3: After receiving the signal from the first sensing device, the control console stops the operation of the hoist and controls the side-discharging mine car to perform side-discharging. After the side-discharging is completed, the control console controls the hoist to transport the side-discharging mine car back to the depth of the inclined shaft;

[0016] Step 4: When the dump truck reaches the second sensing device at the tail of the ballast bin, the second sensing device generates an electrical signal and sends it to the control console;

[0017] Step 5. After receiving the signal from the second sensing device, the control console controls the door of the ballast transfer bin to open to complete the ballast loading. The dump truck transports the ballast to the designated location for the second time. After the ballast transfer bin is unloaded, the door is automatically closed.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The present invention is suitable for waste slag transportation construction on high steep slopes and long inclined shafts. Through the combined action of the sensing device and the control console, the mechanized, intelligent and automated control of the slag discharge system can be achieved, which can improve the slag discharge efficiency and reduce labor costs while ensuring the transportation safety of the waste slag.

[0026] The present invention provides a high-efficiency mucking construction device for a large-slope rail-mounted inclined shaft of a water conveyance tunnel, such as Figure 1 As shown, the device includes a slope plank road 1, a curved track 2, a sheave 3, a wire rope 4, a sheave frame 5, a hoist 6, a control console 7, a side-unloading mine car 8, a first sensing device 9, a dump truck 10, a ballast bin 11 and a second sensing device 12, wherein:

[0027] The slope plank road 1 is arranged at the branch cave entrance;

[0028] The curved track 2 is pre-buried in the concrete of the slope plank road 1;

[0029] A sheave frame 5 is provided on the upper part of the curved track 2 for supporting the sheave 3;

[0030] A hoist 6 is provided in front of the sheave frame 5, and a control console 7 is provided in front of the hoist 6 for controlling the transportation process and providing power;

[0031] The side-discharging mining car 8 is located on the curved track 2 and is connected to the hoist 6 and the sheave 3 through the steel wire rope 4;

[0032] A first sensing device 9 is provided in the middle of the slope plank road 1;

[0033] The ballast bin 11 is located below the first sensing device 9, and a second sensing device is provided at the tail of the ballast bin;

[0034] The signals of the first sensing device 9 and the second sensing device 12 are aggregated to the console 7 .

[0035] In the present invention, the slope of the slope plank road 1 is the same as the slope inside the branch cave.

[0036] In the present invention, the slope plank road 1 is a C25 concrete, paved stone structure, and the curved track 2 is pre-buried in the concrete.

[0037] In the present invention, the sky wheel 3 is a fixed sky wheel with a diameter of 2.0 m.

[0038] In the present invention, the specification of the steel wire rope 4 is 6×19×FC-Φ40.

[0039] In the present invention, the ballast bin 11 is made of manganese steel plate.

[0040] In the present invention, the first sensing device 9 and the second sensing device 12 are photoelectric sensors.

[0041] In the present invention, the mucking construction device further includes a dump truck 10, and the dump truck 10 is used for transporting waste mucking.

[0042] like Figure 2-Figure 4 As shown, the construction process specifically includes the following steps:

[0043] Under the joint action of the hoist 6, the sheave 3, and the wire rope 4, the side-unloading mine car 8 is transported out of the branch tunnel from the deep part of the inclined shaft through the curved track 2 laid on the ramp plank road 1. The side-unloading mine car 8 is transported to the first sensing device 9 in the middle of the curved track 2. The first sensing device 9 generates an electrical signal and sends it to the control console 7. The control console 7 controls the hoist 6 to stop running and controls the side-unloading mine car 8 to side-unload the waste slag to the top of the slag transfer bin 11. After the side unloading is completed, the hoist 6 is controlled to transport the side-unloading mine car 8 back to the deep part of the inclined shaft. When the dump truck 10 reaches the second sensing device 12 at the tail of the slag transfer bin 11, the second sensing device 12 generates an electrical signal and sends it to the control console 7.
