Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically a cleaning device for tunnel boring machines. Background Technology

[0002] A tunnel boring machine (TBM) is a large, specialized piece of machinery used for tunnel excavation. Named for its cylindrical shield-like shape, it advances underground while simultaneously performing tunnel excavation and support structure construction. Integrating excavation, support, muck removal, and grouting functions, it resembles a steel earthworm traversing the earth. In subway, cross-river tunnels, and municipal pipeline construction projects, TBMs have become key equipment due to their high efficiency, safety, and environmental friendliness. Different types can be designed according to different geological conditions, such as earth pressure balance TBMs and slurry balance TBMs, greatly reducing the impact of traditional open-cut construction on surface traffic and the environment, and driving technological innovation in underground space development.

[0003] In existing technologies, when the excavated soil from a tunnel boring machine is discharged via a belt conveyor, it is necessary to promptly remove mud and stones adhering to the conveyor belt to prevent belt misalignment or equipment jamming due to soil accumulation, thus ensuring the efficiency of soil removal. During use, some residual soil will adhere to the soil conveyor belt. Soil adhesion can easily lead to equipment failure and reduce soil conveying efficiency. Moreover, after being cleaned, the soil accumulates together after a long period of collection, increasing the space occupied.

[0004] Therefore, a cleaning device for tunnel boring machines was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning device for tunnel boring machines, which solves the technical problems of residual slag adhering to the slag conveyor belt, which can easily lead to equipment failure and reduce slag conveying efficiency. Furthermore, the cleaned slag accumulates after long-term collection, increasing the space occupied. This device achieves the purpose of cleaning, collecting and compacting slag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for a tunnel boring machine, comprising a slag conveyor belt, wherein concave legs are fixedly installed at equal intervals at the bottom of the slag conveyor belt, and universal wheels are fixedly installed at the bottom of the concave legs; through holes are respectively opened on the front and bottom of the slag conveyor belt; a slag cleaning component is provided on the front of the slag conveyor belt; and a collection and compaction component is provided on the bottom of the slag conveyor belt.

[0007] Preferably, the construction waste cleaning component specifically includes: a slider, which is equidistantly fixedly installed on the front side of the construction waste conveyor belt; a sliding rod, which is slidably connected between the inner walls of the slider; a chute block, which is fixedly installed between the inner sides of the sliding rod; and a mounting plate, which is fixedly installed on the front side of the construction waste conveyor belt.

[0008] Preferably, a motor is fixedly mounted on the surface of the mounting plate, a crossbar is fixedly mounted on the output end of the motor, a drive rod is fixedly mounted on the other end of the crossbar, and the other end of the drive rod extends to the inner wall of the sliding block for sliding connection.

[0009] Preferably, a T-groove block is fixedly sleeved on the outer wall of the slide rod, and an installation block is slidably connected to the inner wall of the T-groove block. A locking hole is opened on one side of the installation block, and a bottom rod is fixedly installed on one side of the installation block. The other end of the bottom rod passes through the interior of the through hole and extends into the interior of the slag conveyor truck. Brush bristles are fixedly installed on the top of the bottom rod.

[0010] Preferably, a guide rod is fixedly installed on one side of the T-groove block, and a nail rod is fixedly installed on one side of the T-groove block. A sliding plate is slidably connected to the outer wall of the guide rod and the outer wall of the nail rod. A spring is movably sleeved on the outer wall of the nail rod. One end of the spring contacts the surface of the nail rod, and the other end of the spring contacts the bottom of the other side of the sliding plate. An insert rod is fixedly connected to the top of one side of the sliding plate, and the other end of the insert rod extends into the interior of the locking hole and engages. The motor drives the crossbar and the drive rod to make the sliding rod slide in the slider, thereby allowing the bristles on the mounting block and the bottom rod to clean the slag conveyor belt.

One end of the second spring contacts one side of the pressure sleeve, and the other end of the second spring contacts one side of the perforated piece. The collection box is installed at the bottom of the slag conveyor belt through the panel, which can collect the slag cleaned from the conveyor belt, prevent the slag from scattering everywhere, and keep the working area clean. The hydraulic rod drives the compaction plate to compact the slag in the collection box, reducing the volume of the slag, facilitating the subsequent transportation and processing of the slag, and improving the efficiency of slag transfer. The structure composed of the perforated piece, T-shaped rod, pressure sleeve, and second spring on one side of the panel can firmly fix the collection box to the bottom of the slag conveyor belt, preventing the collection box from shaking or falling off during use, ensuring the stable operation of collection and compaction, and thus achieving the effect of collection and compaction.

Example

[0032] Based on Embodiment 1, a preferred embodiment of the cleaning equipment for tunnel boring machines provided by this utility model is as follows: Figure 1-6 As shown: The collection and compaction component 6 specifically includes: a panel 611, which is fixedly connected at equal intervals to the bottom of the slag conveyor belt 1; a collection box 612, which is slidably connected between the inner walls of the panel 611; a handle 613, which is fixedly installed on one side of the collection box 612; a recycling trough 614, which is opened on one side of the inner wall of the collection box 612; and a compaction plate 616, which is set between the inner walls of the recycling trough 614.

[0033] Hydraulic rods 615 are fixedly installed at equal intervals on the other side of the collection box 612. The telescopic end of the hydraulic rod 615 moves through the other side of the collection box 612 and extends into the interior of the recycling tank 614, where it is fixedly installed on one side of the compaction plate 616.

[0034] A perforated piece 617 is fixedly installed on one side of the panel 611. A T-shaped rod 618 is slidably connected to the inner wall of the perforated piece 617. One end of the T-shaped rod 618 passes through one side of the collection box 612 and extends into the interior of the collection box 612 to engage with it. A pressure sleeve 619 is fixedly fitted on the outer wall of the T-shaped rod 618. A second spring 6111 is movably fitted on the outer wall of the T-shaped rod 618. One end of the second spring 6111 contacts one side of the pressure sleeve 619, and the other end of the second spring 6111 contacts one side of the perforated piece 617.

[0035] In this example, the collected compaction component 6 can be set up to collect the cleaned slag. The collection box 612 collects the cleaned slag. When a certain amount has been collected, the hydraulic rod 615 is activated to drive the compaction plate 616 to compact the slag, thereby increasing the collection space of the collection box 612 and achieving the function of collection and compaction.

[0036] Working Principle: First, the muck conveyor belt 1 collects and transports the muck generated by the tunnel boring machine. When cleaning the muck conveyor belt 1 is required, to prevent residual muck from adhering, the motor 515 is started, driving the crossbar 516 and drive rod 517 to rotate, causing the chute block 513 and slide rod 512 to slide left and right on the slider 511. The slide rod 512 drives the T-groove block 518, mounting block 519, and bottom rod 5111 to move together, causing the brush bristles 5112 to clean the muck conveyor belt 1 from side to side, causing the adhering residual muck to fall off. The collection box 612 collects the cleaned muck. When a certain amount has been collected, the hydraulic rod 615 is started, driving the compaction plate 616 to compact the muck, improving its quality. When the bristles 5112 need to be replaced, the sliding plate 5115 is pulled to slide on the nail rod 5114 and guide rod 5113, compressing the spring 5116. The sliding plate 5115 drives the insert rod 5117 to disengage from the lock in the mounting block 519, allowing the mounting block 519 to slide out from the T-groove block 518 for replacement of the bristles 5112. When cleaning up slag, the T-shaped rod 618 and pressure sleeve 619 are pulled to compress the spring 6111 on the hollow plate 617, disengaging the T-shaped rod 618 from the lock in the collection box 612. The collection box 612 can be disassembled through the handle 613 to clean up the compacted slag, thus achieving the functions of slag cleaning and collection compaction.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
