Description

Technical Field

[0001] The present invention relates to the technical field of shield construction, and particularly to a shield muck truss vehicle belt conveyor discharging system and a discharging method. Background Art

[0002] The shield tunneling method is widely used in tunnel engineering construction. During the construction process, the muck generated needs to be transported out of the tunnel in a timely manner through an efficient conveying system. At present, the shield muck transportation mainly adopts the continuous belt conveyor conveying method, and the muck is transported from the outlet of the shield machine screw conveyor to the ground muck pond through the belt conveyor.

[0003] However, the existing shield muck conveying system has the following technical defects: Traditional continuous belt conveyors usually adopt a fixed discharging point design, and the muck can only be concentrated and stacked at a single position in the muck pond, resulting in uneven distribution of the muck in the muck pond. It is necessary to rely on excavators for frequent secondary tipping and transfer operations, which not only increases the construction time and mechanical cost, but also may cause safety hazards due to excessive muck stacking. To improve the muck storage capacity, modern shield projects generally adopt a segmented muck pond design, such as dividing the muck pond into several small ponds. However, the traditional belt conveyor cannot achieve multi-point discharging, resulting in ineffective coverage of some areas of the muck pond and reducing the space utilization rate of the muck pond. In the prior art, the distribution and transfer of muck highly depend on manual operation of excavators, with insufficient automation and difficulty in achieving efficient and continuous muck management. This problem is particularly prominent in urban areas with complex construction environments.

[0004] Therefore, there is an urgent need in the art to develop a new type of shield muck conveying system that can achieve efficient, automated, and multi-point uniform discharging of muck, so as to improve the utilization rate of the muck pond, reduce secondary operations, and ultimately ensure the continuity and economy of shield construction. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, the present invention provides a shield muck truss vehicle belt conveyor discharging system and a discharging method, which solve the problem that the existing muck transportation system cannot achieve multi-point discharging.

[0006] In a first aspect, in order to achieve the above object, the technical solution adopted by the present invention is: A shield muck truss vehicle belt conveyor discharging system includes a continuous belt conveyor, a distributing belt conveyor, a discharging trolley, a muck pond, and a monitoring and control system; one end of the continuous belt conveyor is connected to a shield tunneling machine inside the tunnel, and the other end of the continuous belt conveyor is provided with a distributing belt conveyor; a discharging trolley is arranged on the distributing belt conveyor, and a muck pond is arranged at the bottom of the distributing belt conveyor; the discharging trolley is connected to the monitoring and control system.

[0007] In this solution, a continuous belt conveyor is used to transport the muck generated by shield tunneling to a distributing belt conveyor outside the tunnel. The discharging trolley travels along the distributing belt conveyor. When it reaches above the muck pit, it pushes the muck on the distributing belt conveyor into the muck pit. This design allows the distributing belt conveyor to cover the entire muck pit, enabling discharging at any position above the muck pit, achieving multi-point discharging and improving the muck transportation efficiency.

[0008] Furthermore, the distributing belt conveyor includes a truss structure and a transmission belt. The transmission belt is installed on the top of the truss structure through a number of idler mechanisms. The discharging trolley includes a vehicle frame. A first driving wheel and a second driving wheel are installed on the vehicle frame. The transmission belt successively passes around the top of the first driving wheel and the bottom of the second driving wheel. The second driving wheel is located below the first driving wheel and on the side away from the muck transportation direction. A three-way discharging port is also installed on the vehicle frame. The muck on the transmission belt falls into the feeding port of the three-way discharging port after reaching the first driving wheel, and then falls into the muck pit below the transmission belt through the two discharging ports of the three-way discharging port.

[0009] In this solution, the muck is transported along the transmission belt. When the muck reaches the position of the first driving wheel, due to the formation of a height difference between the first driving wheel and the second driving wheel, the muck falls into the feeding port of the three-way discharging port under the action of gravity. The two discharging ports of the three-way discharging port are respectively arranged on both sides of the transmission belt. Therefore, the muck falling into the three-way discharging port drops into the muck pit from the discharging ports on both sides of the transmission belt. This design allows the discharging trolley to travel along the truss structure, travel and stop above one of the muck pits, and then push the muck on the transmission belt into the muck pit. During actual operation, multi-point discharging can be carried out, providing time and space for the transportation of the muck inside the muck pit.

[0010] Furthermore, the truss structure includes a main truss and supporting legs. The supporting legs are built on the top of the muck pit, and the main truss is installed on the supporting legs. The main truss is arranged along the direction of muck transportation by the transmission belt. Two rows of support columns are provided on the top of the main truss. Two I-beams are respectively supported on the tops of the two rows of support columns. The transmission belt is installed between the two I-beams through a number of idler mechanisms. Two rails are respectively laid on the two I-beams, and the discharging trolley travels on the rails.

[0011] Furthermore, the idler mechanism includes an upper idler assembly and a lower idler assembly. The upper idler assembly includes three split idlers distributed in a trapezoidal groove shape. The three split idlers are installed between the two I-beams through an upper support. The lower idler assembly includes an integral idler. The integral idler is connected to the bottom of the upper support through a lower support. The transmission belt passes around the top of the split idlers and the bottom of the integral idler.

[0012] In this solution, three split idlers are distributed in a trapezoidal groove shape. When the conveyor belt supports and moves on them, it also presents the same trapezoidal groove structure. The soil inside the inner groove of the muck is transported, avoiding the muck from falling from both sides of the conveyor belt during transportation.

[0013] Further, walking wheels are provided at the bottom of the frame, and the walking wheels run on the rails; a walking motor is installed on the frame, and the walking motor is in transmission connection with the walking wheels.

[0014] In this solution, the walking motor provides power to drive the walking wheels to rotate, so as to travel along the rails, facilitating discharging at any position.

[0015] Further, a guiding frame is connected to the top of the frame, and one end of the guiding frame away from the frame is inclined downward; several guiding idlers are installed on the guiding frame; When the conveyor belt passes through the position of the discharging trolley, it successively bypasses several guiding idlers, a first driving wheel and a second driving wheel on the guiding frame, and then winds back to the idler mechanism on the truss structure.

[0016] In this solution, the conveyor belt moves along the guiding idlers on the guiding frame, so that the muck is slowly transported to the height of the first driving wheel, avoiding a large height difference when the conveyor belt directly goes from the idler mechanism to the first driving wheel.

[0017] Further, several muck ponds are arranged along the direction of the conveyor belt transporting the muck.

[0018] Further, the monitoring and control system includes a console and a laser displacement sensor, a tension sensor and a position sensor connected to the console; the laser displacement sensor is arranged at the bottom of the truss structure for monitoring the real-time height of the muck in the muck pond below; the tension sensor is arranged on the conveyor belt for detecting the tension of the conveyor belt; the position sensor is installed on the discharging trolley for real-time monitoring of the position information of the discharging trolley.

[0019] In this solution, no less than 2 laser displacement sensors are arranged above each partition of the muck pond according to the size of the muck pond. The console obtains the real-time monitoring data of the laser displacement sensors, and controls the discharging trolley to move to the corresponding position for discharging through an intelligent path planning algorithm, realizing uniform discharging. When the tension sensor monitors that the belt tension exceeds the specified threshold range, the console triggers an emergency stop protection to stop the system operation. The position sensor real-time monitors the position information of the discharging trolley, and provides data support for the console to control the moving speed of the discharging trolley and the belt speed of the conveyor belt through an intelligent path planning algorithm in combination with the partition information of the muck pond and the dynamic belt load.

[0020] In a second aspect, based on the shield muck truss vehicle belt conveyor discharging system provided in the first aspect, the present invention provides a method for discharging shield muck by a truss vehicle belt conveyor, including the following steps: Step 1, Muck transportation: The continuous belt conveyor transports the muck from the outlet of the screw conveyor of the shield tunneling machine to the transfer belt outside the tunnel; Step 2, Batching operation: The discharging trolley stops above one of the muck ponds. The muck is transported along the transfer belt to the top of the discharging trolley and falls into the feeding port of the three-way discharging port. Finally, it falls from the two discharging ports of the three-way discharging port into the muck pond below the transfer belt; Step 3, Movement of the discharging trolley: When the muck pond below the discharging trolley is filled with muck, the discharging trolley travels along the railway track, travels and stops directly above the next muck pond, and continues to pour the muck into this muck pond; Step 4, Muck transportation: Use transportation equipment to transport the muck inside the muck pond away.

[0021] The beneficial effects of the present invention are: In the shield muck truss vehicle belt conveyor discharging system of the present invention, the muck is first transported from the inside of the tunnel to the transfer belt by the continuous belt conveyor, and the muck continues to be transported along the transfer belt; at the same time, the discharging trolley can move along the truss structure. When it moves above one of the muck ponds, the discharging trolley pushes the muck on the transfer belt into the corresponding muck pond below; when this muck pond is filled with muck, the discharging trolley continues to move, moves above the next muck pond, and pushes the muck on the transfer belt into the next muck pond. Since the transfer belt covers the entire muck pond, discharging can be performed at any position above the muck pond, realizing multi-point discharging, improving the muck transportation efficiency, and solving the technical problems of uneven batching, small coverage range, and low automation degree existing in the traditional shield muck discharging system. While performing multi-point discharging, the transportation personnel can transport the muck in the filled muck pond through transportation equipment, providing time and space for the transportation of the muck.

[0026] The specific structure of the cloth belt conveyor 2 is as follows: As Figure 3 shown, the cloth belt conveyor 2 includes a truss structure 21, a roller mechanism 23, and a conveyor belt 22. The conveyor belt 22 is installed on the top of the truss structure 21 through a number of roller mechanisms 23.

[0027] As Figure 4 shown, the truss structure 21 includes a main truss 211 and legs 212. The legs 212 are built on the top of the muck pond 4, and the main truss 211 is installed on the legs 212; the main truss 211 is arranged along the direction of transporting muck by the conveyor belt 22; two rows of support columns 213 are provided on the top of the main truss 211, and two I-beams 214 are respectively supported on the tops of the two rows of support columns 213. The conveyor belt 22 is installed between the two I-beams 214 through a number of roller mechanisms 23; two rails 215 are respectively laid on the two I-beams 214, and a discharging trolley 3 travels on the rails 215.

[0028] The main truss 211 is a structure welded by Q355 H-shaped steel into a shape similar to a military portable beam; the main truss 211 mainly plays a supporting role for the conveyor belt 22 and the rails 215, so as long as its structure has high strength.

[0029] The legs 212 are mainly used to support the main truss 211 to ensure the stability of the equipment; they are welded by Q355 H-shaped steel into a scissors brace. Considering the path of the excavator bucket, the position of the discharging port and the height of the discharging port of the continuous belt conveyor 1, the height and installation position of the scissors brace are determined, and a leg 212 is set every 6 meters.

[0030] The roller mechanism 23 includes an upper roller assembly and a lower roller assembly; The upper roller assembly includes three split rollers 231 distributed in a trapezoidal groove shape. The three split rollers 231 are installed between the two I-beams 214 through an upper bracket 232; the lower roller assembly includes an integral roller 233, and the integral roller 233 is connected to the bottom of the upper bracket 232 through a lower bracket 234; the conveyor belt 22 is arranged around the tops of the split rollers 231 and the bottom of the integral roller 233.

[0031] The specific structure of the discharging trolley 3 is as follows: As Figure 5As shown in the figure, the discharging trolley 3 includes a vehicle frame 31.

The muck is transported along the conveying belt 22. When the muck is transported to the position of the first driving wheel 33, due to the formation of a height difference between the first driving wheel 33 and the second driving wheel 34, the muck falls into the feeding port of the three-way discharging port 35 under the action of gravity. The two discharging ports of the three-way discharging port 35 are respectively arranged on both sides of the conveying belt 22. Therefore, the muck falling into the three-way discharging port 35 falls into the muck pit 4 from the discharging ports on both sides of the conveying belt 22; with this design, the discharging trolley 3 can travel along the truss structure 21, travel and stop above one of the muck pits 4, and then push the muck on the conveying belt 22 into the muck pit 4.

[0033] A guiding frame 32 is connected to the top of the vehicle frame 31, and one end of the guiding frame 32 far from the vehicle frame 31 is inclined downward; a plurality of guiding rollers 36 are installed on the guiding frame 32; When the conveying belt 22 passes through the position of the discharging trolley 3, it sequentially bypasses a plurality of guiding rollers 36 on the guiding frame 32, the first driving wheel 33 and the second driving wheel 34, and then winds back to the roller mechanism 23 on the truss structure 21. The conveying belt 22 moves along the guiding rollers 36 on the guiding frame 32, so that the muck is slowly transported to the height of the first driving wheel 33, avoiding a large height difference when the conveying belt 22 directly goes from the roller mechanism 23 to the first driving wheel 33.
