Description

Technical Field

[0001] This invention relates to the field of TBM tunnel transportation, and in particular to a TBM tunnel slag removal and waste disposal device. Background Technology

[0002] A mining TBM is a large-scale piece of equipment used for excavating underground rock tunnels. This equipment boasts advantages such as high tunneling efficiency, synchronous anchor support, and safe operation. Existing mining TBMs consist of a main unit and a supporting system. The excavated material from the mining TBM is transferred to the supporting system via a transfer conveyor inside the main unit. The supporting system, equipped with a continuous belt conveyor, connects to the mine's continuous belt conveyor, transporting the excavated material out of the tunnel. This tunneling method requires the mine to match the continuous belt conveyor installation schedule to the TBM's tunneling speed. The continuous belt conveyor needs to be fixed to the bottom of the rock tunnel, reducing the efficiency of space utilization within the tunnel. Furthermore, this type of continuous belt conveyor for excavation can only achieve a minimum turning radius of 80 meters, making it unsuitable for excavating some special rock tunnels.

[0016] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0018] Reference Figure 1 This embodiment provides a TBM tunnel slag discharge and waste disposal device, including a TBM tail trailer 1, which includes a conveying component 11 disposed on the TBM tail trailer 1; a transfer assembly 2; and a swing assembly 3, which includes a swing component 31 disposed on the TBM tail trailer 1 and the transfer assembly 2 for connecting the TBM tail trailer 1 and the transfer assembly 2, and a push-pull assembly 32 disposed on the TBM tail trailer 1 and the transfer assembly 2 for controlling the swing angle of the transfer assembly 2.

[0019] It also includes two trackless rubber-wheeled vehicles 4, which are located below the transfer assembly 2.

[0020] Specifically, there are two push-pull components 32, and the two push-pull components 32 are arranged symmetrically. The TBM tail trailer 1 and the transfer component 2 are hinged together by the swing member 31.

[0021] It should be noted that the tunnel d excavated by the TBM is circular, and the bottom e is paved. When the trackless rubber-tired vehicle 4 is not located under the transfer component 2, the crushed rock falls directly to the bottom of the tunnel d. Through manual labor or compaction equipment, the bottom of the tunnel d is changed from circular to flat, forming the tunnel bottom e. Only then can two trackless rubber-tired vehicles 4 be placed side by side. If the bottom is not paved, under normal circumstances, only one trackless rubber-tired vehicle 4 can collect the material under the transfer component 2 in the circular tunnel d.

[0022] In operation, the push-pull assembly 32 causes the transfer assembly 2 to swing counterclockwise / clockwise via the swing member 31, positioning the discharge port of the transfer assembly 2 above one of the trackless rubber-tired trolleys 4. Subsequently, the excavated slag from the mining TBM is transferred via a belt conveyor within the main unit to the conveyor 11 within the TBM tail trailer 1. The slag is then conveyed by the conveyor 11 to the transfer assembly 2, which transfers the slag into the trackless rubber-tired trolleys 4. When one of the trackless rubber-tired trolleys 4 is full, the push-pull assembly 32 causes the transfer assembly to... Component 2 swings clockwise or counterclockwise via swing component 31, positioning the discharge port of transfer component 2 above another trackless rubber-tired vehicle 4. This allows the slag to fall onto the trackless rubber-tired vehicle 4 via transfer component 2. When one of the trackless rubber-tired vehicles 4 is full, it moves to the unloading site to unload. After unloading, it returns to its original position, enabling the two trackless rubber-tired vehicles 4 to transport and unload materials back and forth. This achieves uninterrupted slag and waste collection operations for the trackless rubber-tired vehicles 4, achieving seamless cyclic slag and waste removal from the slag generated during TBM tunneling and improving the utilization efficiency of space within the rock tunnel. The conveyor component 11 and the transfer component 2 adopt a zigzag overlap method, which can achieve a minimum turning radius of 15m for the slag discharge system, breaking through the limitation that the continuous belt conveyor equipped with a traditional TBM can achieve a minimum turning radius of 80m.

[0023] Reference Figures 2 to 4 As an optional embodiment: the transfer component 2 includes a support body 21, a first support frame 22 is provided inside the support body 21, a transfer belt conveyor 23 is provided on the first support frame 22, and a guide component 24 is provided on the support body 21.

[0024] Specifically, the support body 21 is provided with a discharge port a, through which the slag is transported to the trackless rubber-wheeled vehicle 4 via the transfer belt conveyor 23. The first support frame 22 is fixedly connected to the bottom wall of the support body 21, the transfer belt conveyor 23 is fixedly installed on the first support frame 22, and the guide component 24 is fixedly installed on the first support frame 22 to guide the material and ensure that the slag falls onto the transfer belt conveyor 23.

[0025] The conveyor 11 includes a second support frame 111 located inside the TBM tail trailer 1. The second support frame 111 is equipped with a material discharge conveyor belt 112 and a slot 113 located on the side wall of the TBM tail trailer 1. The material discharge conveyor belt 112 is connected to the support base 311.

[0026] The material feeding conveyor belt 112 extends through the slot 113 to the top of the guide body 242.

[0027] Specifically, the second support frame 111 is fixedly connected to the inner wall of the TBM tail trailer 1, and the discharge conveyor belt 112 is fixedly installed on the second support frame 111. The slot 113 is connected to the inside of the TBM tail trailer 1. It should be noted that a guide plate can be set inside the TBM tail trailer 1 to ensure that the slag falls onto the discharge conveyor belt 112. Depending on the actual situation, the discharge conveyor belt 112 can extend out of the TBM tail trailer 1 through the slot 113.

[0028] During operation, the slag produced by the mining TBM is transferred to the unloading conveyor 112 in the tail trailer 1 of the TBM via a conveyor belt inside the main unit. The unloading conveyor 112 is started to move the slag gradually onto the transfer conveyor belt. When the slag leaves the unloading conveyor 112, it is guided to the transfer conveyor 23 by the guide component 24. At the same time, the transfer conveyor 23 is started, and the slag is gradually lifted by the transfer conveyor 23 and moved to the trackless rubber-tired car 4. Under the action of the transfer conveyor 23, the slag falls into the trackless rubber-tired car 4 through the discharge port a, so that the cargo bin b of the trackless rubber-tired car 4 receives the slag. The material discharge conveyor 112 and the transfer conveyor 23 adopt a zigzag overlapping method, which can achieve a minimum turning radius of 15m for the slag discharge system, breaking through the limitation that the continuous conveyor belt equipped with a traditional TBM can achieve a minimum turning radius of 80m.

[0029] Reference Figure 5 As an optional embodiment: the guide member 24 includes a support frame 241 disposed on the support body 21, and a guide body 242 disposed on the support frame 241; the guide body 242 is provided with an A end 2421 and a B end 2422 that is larger than the surface area of ​​the A end 2421; the B end 2422 is D-shaped.

[0030] Specifically, end A 2421 is circular, while end B 2422, which is D-shaped, reduces the occupied area and still ensures accurate guidance of slag and stone when the conveyor belt 23 undergoes small angle changes.

[0031] When in use, when the slag is conveyed by the discharge conveyor 112 to the top of the transfer conveyor 23 and detaches from the discharge conveyor 112, it falls onto the transfer conveyor 23 under the guidance of the guide body 242, ensuring that the slag falls onto the transfer conveyor 23.

[0032] Reference Figures 2 to 7 As an optional embodiment: the swing member 31 includes a support seat 311 provided on the tail trailer 1 of the TBM and a connecting seat 312 provided on the support body 21. The support seat 311 and the connecting seat 312 are both provided with a hinge pin 313; the connecting seat 312 is hinged to the support seat 311 through the hinge pin 313.

[0033] Specifically, the support base 311 is fixedly connected to the TBM tail trailer 1, and the connecting base 312 is fixedly connected to the support body 21. The hinge pin 313 is fixedly installed in the pin mounting hole c where the support base 311 and the connecting base 312 overlap. By hingedly connecting the connecting base 312 and the support base 311, the angle of the material discharge port can be adjusted, enabling the two trackless rubber-wheeled vehicles 4 to discharge and transport waste materials back and forth.

[0034] The push-pull assembly 32 includes a support block 321 on the rear trailer 1 of the TBM and a connecting block 322 on the support body 21. A telescopic member 323 is provided between the support block 321 and the connecting block 322.

[0035] Specifically, the support block 321 is fixedly connected to the TBM tail trailer 1, the connecting block 322 is fixedly connected to the support body 21, and the telescopic component 323 is rotatably connected to the support block 321 and the connecting block 322.

[0036] The telescopic component 323 includes a telescopic cylinder 3231 and connecting rotating blocks 3232 located at both ends of the telescopic cylinder 3231; the two connecting rotating blocks 3232 are rotatably connected to the support block 321 and the connecting block 322 respectively; the telescopic cylinder 3231 can extend and retract to cause the support body 21 to shift at an angle.

[0037] Specifically, the two connecting blocks 3232 are fixedly installed at both ends of the telescopic cylinder 3231.

[0038] In operation, the telescopic cylinder 3231 is activated. The front telescopic cylinder 3231 extends, and the rear telescopic cylinder 3231 retracts. At this time, the support body 21 rotates counterclockwise under the action of the hinge pin 313. The material discharge port is then positioned above the rear trackless rubber-tired cart 4, allowing the slag to be transported to the rear trackless rubber-tired cart 4 via the transfer belt conveyor 23. When the trackless rubber-tired cart 4 is full of slag, the front telescopic cylinder 3231 retracts, and the rear telescopic cylinder 3231 extends. At this time, the support body 21... Body 21 is deflected clockwise by the hinge pin 313, so that the discharge port is above the trackless rubber-tired car 4 on the front side. The slag is then transported to the trackless rubber-tired car 4 on the front side by the transfer belt conveyor 23. When one of the trackless rubber-tired cars 4 is full, it moves to the unloading site to unload. After unloading, it returns to its original position, realizing the back-and-forth material transportation and unloading of the two trackless rubber-tired cars 4. This achieves the uninterrupted slag and waste collection operation of the trackless rubber-tired cars 4, and achieves the purpose of seamless cyclic slag and waste removal work for the slag generated during TBM tunneling.

[0039] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
