Description

Technical Field

[0001] The present invention relates to the technical field of tunnel excavation, and more particularly to a slag conveying device for a tunnel boring machine. Background Art

[0002] The tunnel boring machine is a tunnel construction machine that uses a rotary cutter to dig, crush the surrounding rock in the hole and excavate to form the entire tunnel section. The tunnel boring machine uses mechanical rock crushing, mucking and support to perform continuous operations. It is equipped with a variety of cutters, such as roller cutters, tooth cutters, scrapers, etc. These cutters crush rocks through different excavation mechanisms. For example, the roller cutter produces cracks by rolling the rock surface, and eventually breaks the rock over a large area. During the tunnel excavation process, a large amount of slag will be generated. If the slag is not transported out in time, it will accumulate in front of the tunnel boring machine, hindering the normal operation of the tunnel boring machine. Therefore, in order to maintain construction efficiency, the slag needs to be transported in time.

[0003] Among them, the patent with announcement number CN106121672A discloses a slag conveying device for a tunnel boring machine and a tunnel boring machine. The slag conveying device includes: a soil bin for receiving slag, a liquid configuration mechanism, which transfers the configured liquid into the soil bin to convert the slag in the soil bin into slurry, and a slurry conveying mechanism, which includes a screw conveyor connected to the soil bin and a pumping mechanism connected to the screw conveyor, so as to continuously convey the slurry to the outside of the tunnel; When in use, the structure continuously transports solid debris to the outside of the tunnel in the form of fluid slurry, which greatly increases the amount of debris transported and avoids the accumulation of debris in the tunnel. However, the structure is not easy to receive the broken debris when in use, resulting in low soil transportation efficiency, and converting it into mud is not convenient for the subsequent secondary use of the debris. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a slag conveying device for a tunnel boring machine, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a slag conveying device for a tunnel boring machine, comprising a reinforced support frame, on which a crushing and conveying assembly is arranged; The crushing and conveying assembly comprises a positioning vertical shaft arranged on the top of the reinforced support frame, a deflection frame for support is rotatably connected to the positioning vertical shaft, and the deflection frame is hinged with an angle-adjustable extension seat; A slag receiving plate with an adjustable angle is hinged at one end of the reinforced support frame, a slag receiving bucket is fixedly arranged at one end of the slag receiving plate, soil-collecting plates for blocking slag are arranged on both sides of the slag receiving plate, two rotating disks are rotatably connected to the slag receiving plate, a plurality of first soil-moving rods are fixedly arranged on the outer sides of the two rotating disks, and a second soil-moving rod is fixedly arranged on the top of each of the first soil-moving rods; Two fourth electric push rods are hingedly connected to one side of the slag receiving plate, and the output end of each of the fourth electric push rods extends to one end of the reinforced support frame and is hingedly connected to the reinforced support frame, and a transfer conveyor belt is arranged between the two fourth electric push rods; It can be seen that in the above technical solution, through the setting of the soil gathering plate, the fallen debris can be blocked, and the debris is easily gathered in the debris receiving bucket. At the same time, the debris is transported to the conveyor through the transfer conveyor belt in the debris receiving bucket and then discharged through the conveyor. At the same time, when discharging the soil, the output end of the fourth electric push rod will be displaced to drive the debris receiving bucket and the debris receiving plate to rotate along the axis point of the connection between the debris receiving plate and the reinforced support frame, so as to realize the function of receiving the debris generated during excavation and prevent the debris from falling into the tunnel.

[0006] Optionally, in a possible implementation, the cross-sectional shape of the two soil-polymer plates is set to an arc shape, and the bottom of each turntable is provided with a second drive motor for driving the turntable to rotate, the second drive motor is embedded in the slag receiving plate, and a protective cover is provided at one end of the transfer conveyor belt, the protective cover is located in the middle of the reinforced support frame, and one end of the protective cover passes through the reinforced support frame and extends to the outside of the reinforced support frame, one end of the extension seat is installed with a connecting seat by bolts, one end of the connecting seat is provided with a first drive motor, and one end of the first drive motor is installed with a sealing sleeve by bolts; It can be seen that in the above technical solution, the turntable is driven to rotate by the second driving motor, which then causes the first soil-moving rod and the second soil-moving rod to rotate. When the first soil-moving rod and the second soil-moving rod rotate, the soil above the slag bucket is moved, thereby improving the transportation efficiency of the soil, avoiding the accumulation of soil, and facilitating its transfer to the transfer conveyor belt and conveyor.

[0007] Optionally, in a possible embodiment, the sealing sleeve is rotatably connected to a limiting cylinder, the output end of the first drive motor extends into the limiting cylinder, one end of the limiting cylinder is rotatably connected to a crushing block, and the output end of the first drive motor extends to the crushing block, the vertical cross-sectional shape of the crushing block is set to a spiral shape, and a plurality of mounting blocks are fixedly arranged on the outer side of the crushing block, a plurality of mounting blocks are threadedly connected to crushing blocks, and a crushing head is fixedly arranged at one end of each crushing block, first electric push rods are hinged on both sides of the connecting seat, and the output end of each of the first electric push rods extends to the sealing sleeve and is hinged to the sealing sleeve, second electric push rods are hinged on both sides of the extension seat, and the output end of each of the second electric push rods extends to the connecting seat and is hinged to the connecting seat, a rear extension plate is provided on the side of the positioning vertical axis away from the deflection frame, third electric push rods are hinged on both sides of the rear extension plate, and the output end of each of the third electric push rods extends to the deflection frame and is hinged to the deflection frame, and a protective cover is provided on the top cover of the extension seat; It can be seen that in the above technical scheme, the angles of the deflection frame, the extension seat, the connecting seat, the first drive motor and the sealing sleeve are adjusted, and then the second electric push rod drives the first drive motor to drive the sealing sleeve, the limit cylinder and the crushing block to adjust the angles of various structures. The first electric push rod drives the first drive motor, the sealing sleeve, the limit cylinder and the crushing block to extend, so that the crushing block can be close to the slag received by the slag bucket and the slag receiving plate, which makes it easy for the crushing block to crush the slag above the slag bucket and the slag receiving plate when rotating, avoiding large slag blocks from clogging the device, ensuring the transportation efficiency and effect, and also facilitating the subsequent secondary use of the slag for landfill. At the same time, the first drive motor drives the crushing block, the mounting block and the crushing block to rotate and crush the slag, and the sealing sleeve can effectively ensure its sealing performance, avoid mud and water from entering the first drive motor, and ensure the sealing performance.

[0008] Technical effects and advantages of the present invention: The present invention drives the slag receiving bucket and the slag receiving plate to rotate along the axis point of the connection between the slag receiving plate and the reinforced support frame when the output end of the fourth electric push rod is displaced, thereby realizing the function of receiving the slag generated during excavation and preventing the slag from falling into the tunnel; The slag in the present invention is transported from the slag receiving bucket to the conveyor through the transfer conveyor belt and then discharged through the conveyor. At the same time, when discharging the slag, the second driving motor drives the turntable to rotate, thereby rotating the first soil-moving rod and the second soil-moving rod. When the first soil-moving rod and the second soil-moving rod rotate, the slag above the slag receiving bucket is moved, thereby improving the transportation efficiency of the slag, avoiding the slag from piling up, and conveniently transferring the slag to the transfer conveyor belt and the conveyor. The third electric push rod of the present invention drives the deflection frame to rotate on the positioning vertical axis, and then adjusts the angles of the deflection frame, the extension seat, the connecting seat, the first driving motor and the sealing set, so that the crushing block can be close to the slag received by the slag receiving bucket and the slag receiving plate, so that the slag above the slag receiving bucket and the slag receiving plate can be crushed when the crushing block rotates, so as to avoid large slag blocks from clogging the device, thereby ensuring the transportation efficiency and effect, and facilitating the subsequent secondary use of the slag for landfill. The crushing block, the mounting block and the crushing block are driven by the first driving motor to rotate to crush the slag, and the sealing set can effectively ensure its sealing performance, avoid muddy water from entering the first driving motor, and ensure the sealing performance; To summarize, through the corresponding coordinated use of various structures, when the output end of the fourth electric push rod is displaced, it will drive the slag receiving bucket and the slag receiving plate to rotate along the axial point of the connection between the slag receiving plate and the reinforced support frame, thereby realizing the function of receiving the debris generated during excavation and preventing the debris from falling into the tunnel. The second drive motor drives the turntable to rotate, and then the first soil-moving rod and the second soil-moving rod rotate. When the first soil-moving rod and the second soil-moving rod rotate, they move the debris above the slag receiving bucket, thereby improving the transportation efficiency of the debris and avoiding the debris from piling up, which is convenient for transferring it to the transfer conveyor belt and the conveyor. When the crushing block rotates, it will crush the debris above the slag receiving bucket and the slag receiving plate to avoid large debris blocks from clogging the device, thereby ensuring the transportation efficiency and effect, and also facilitating the subsequent secondary use of the debris for landfill.
