Description

Technical Field

[0001] This invention belongs to the technical field of tunnel excavation equipment, and in particular relates to a slag removal device, slag removal system and tunneling machine. Background Technology

[0002] During tunnel boring machine (TBM) excavation, a large amount of debris accumulates at the tunnel bottom due to factors such as fractured faults, support collapses, and the excavator shoe crushing the tunnel walls. If this debris is not cleaned up in time, it will affect the movement of the trailer trucks and thus reduce tunneling efficiency. This is especially true for small TBMs, where tunnel space is limited, and debris accumulation at the bottom can severely hinder tunneling progress.

[0003] Traditional slag removal methods involve manual slag removal, which is in harsh environments and requires high labor intensity. To address this issue, utility model patent CN210598984U (authorization announcement date: May 22, 2020) discloses a novel hard rock TBM slag removal device. This device includes a movable slag removal and conveying integrated machine suspended on the TBM main unit. During operation, a circular pusher scrapes slag onto a conveying mechanism, which then transports the slag fragments to a branch of the main unit's belt conveyor. This allows for more comprehensive slag removal and a higher degree of automation.

[0004] However, for small tunnel boring machines (TBMs), the limited operating space inside the tunnel makes it difficult to install automated muck collection and cleaning devices. For example, the muck collection and cleaning device in the aforementioned utility model patent involves hoisting an integrated muck-loading and conveying machine onto the TBM main unit. The muck cleaning process includes three actions: muck loading, muck collection, and conveying. This requires conveying the broken muck upwards, occupying considerable vertical space. Furthermore, the TBM main unit or connecting bridge also houses other equipment, resulting in insufficient assembly space and making it difficult to implement in small TBMs.

[0005] Therefore, it is necessary to design a slag removal device for tunneling machines that is easy to arrange and occupies little space. Summary of the Invention

[0006] The purpose of this invention is to provide a muck removal device and system for a tunneling machine, solving the technical problem that the existing muck removal device for tunneling machines requires a large space for arrangement. Another purpose of this invention is to provide a tunneling machine that solves the technical problem of low automation in muck collection and removal caused by the difficulty in arranging a muck removal system.

[0007] To achieve the above objectives, the technical solution of the tunneling machine slag removal device provided by the present invention is as follows:

The hinge point is above the hinge position with the shovel arm, and the other end of the first pitch cylinder is hinged to the shovel arm.

[0009] The beneficial effects are as follows: the forward and backward movement of the shovel arm pushes the pusher to push and scoop up slag; the tilting movement of the shovel arm causes the pusher to rise and overturn the slag; and the extension and retraction of the first tilting cylinder causes the pusher to flip backward around the hinge point with the shovel arm to unload the slag. The slag collection operation of the slag cleaning device in this invention is completed through the movements of the shovel arm and the pusher, achieving a high degree of automation. At the same time, the movement amplitude is small, there is no need for upward conveying, and it occupies little space.

[0087] The present invention will be further described in detail below with reference to the embodiments.

[0088] Specific embodiment 1 of the tunneling machine slag removal system provided by the present invention:

[0089] The structure of the tunneling machine slag removal system provided in this embodiment is as follows: Figure 1 As shown, the system includes a belt conveyor 5 and a slag removal device. The slag removal device consists of a frame 1, a pusher 3, a shovel arm 4, a propulsion cylinder 7, a first pitch cylinder 8, a second pitch cylinder 9, and a chute assembly 2. In use, the frame 1 is connected to the trailer 6 of the tunneling machine. Figure 2 As shown, the belt conveyor 5 is arranged in the middle of the frame 1, and the shovel arm 4, the propulsion cylinder 7, the first pitch cylinder 8, the second pitch cylinder 9 and the chute assembly 2 are located on the left and right sides of the frame.

[0090] like Figures 1-9 As shown, the propulsion cylinder 7 is mounted on the frame, with one end connected to the slider 15. The slider 15 slides back and forth along the slide groove 14. A connecting seat 17 is provided on the slider 15. The rear end 21 of the shovel arm is hinged to the connecting seat 17, and the front end 18 of the shovel arm is hinged to the pusher 3. The first pitch cylinder 8 is hinged to the shovel arm 4 through the first pitch cylinder lug 19, and the second pitch cylinder 9 is hinged to the frame through the second pitch cylinder lug 20. Under the action of the propulsion cylinder 7, the shovel arm 4 can move forward, pushing the pusher 3 forward to push and shovel slag. Under the action of the second pitch cylinder 9, the shovel arm 4 can perform pitching motion, driving the pusher 3 to turn over slag. Under the action of the first pitch cylinder 8, the pusher 3 can maintain a stable shoveling posture or unload slag backward.

[0091] like Figures 4-6 As shown, the slide rail assembly 2 includes an anti-deviation groove 10, a cover plate 11, an oil cup 12, an oil channel 13, a slide rail 14, a slider 15, a connecting plate 16, and a connecting seat 17. The slide rail assembly 2 is connected to the frame 1 by structural steel. The anti-deviation groove 10 and the slider 15 are connected by bolts and move with the slider 15. When the shovel arm 4 moves, a section of it is always placed in the anti-deviation groove 10, which can limit the lateral displacement of the shovel arm 4 and provide lateral protection. The two anti-deviation grooves 10 are connected by the connecting plate 16 to ensure the synchronous movement of the sliders 15 on both sides, resulting in better stability. The cover plate 11, oil cup 12, oil channel 13, and slide rail 14 together form a sliding sealed oil groove, allowing the slider 15 to slide stably back and forth and withstand relatively large reaction forces.

[0092] like Figure 8 and Figure 9 As shown, the pusher 3 includes a concave arc-shaped plate 22 at the bottom and a discharge port 23 at the rear center, with the lower edge of the discharge port 23 higher than the arc-shaped plate 22. During shoveling, due to gravity, the debris concentrates in the center. During discharge, the debris is discharged from the discharge port 23, allowing the pusher to complete the discharge action without requiring a large movement. A shovel plate 25 is provided on the arc-shaped plate 22, with its front end fixedly connected to the arc-shaped plate 22 and its rear end connected to the discharge port 23. Transition slopes are also provided between the shovel plate 25 and the arc-shaped plate 22 on both sides, enhancing the pusher's strength and facilitating the scraping of debris from the discharge port 23. Furthermore, alloy rake teeth 24 are provided at the front end of the arc-shaped plate 22 to improve the pusher's service life. A rubber sheet is also provided at the discharge port 23 to prevent debris from scattering in all directions during discharge.

[0093] The working principle of the tunneling machine slag removal system in this embodiment is as follows:

[0094] During normal tunneling, the muck removal system moves forward with the trailer. When there is debris at the bottom of the tunnel that needs to be removed, the tunneling machine stops tunneling, and the cleaning system starts working. The working process includes the following three steps:

[0095] In the first step, the pusher 3, under the action of the propulsion cylinder 7, continuously pushes and shovels the slag, such as... Figure 10 As shown. At this time, the first pitching cylinder 8, together with the shovel arm 4 and the pusher 3, forms a stable triangular structure, which can realize a stable shoveling action.

[0096] The second step involves tilting the slag under the action of the second tilting cylinder 9, such as... Figure 11 As shown. At this time, the propulsion cylinder 7 retracts, the second tilt cylinder 9 drives the shovel arm to move, and the pusher 3 is raised to realize the slag-turning action. The first tilt cylinder 8 is adjusted appropriately according to the slag condition inside the pusher to prevent slag from spilling out.

[0097] The third part involves unloading slag under the action of the first pitching cylinder 8, such as... Figure 12 As shown. At this time, the first pitching cylinder 8 is retracted, the pusher 3 tilts backward, and the slag is discharged from the slag discharge port into the belt conveyor 5. The belt conveyor 5 then transports the slag out backward.

[0098] The specific embodiment 2 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the slag removal device's shovel arm 4 is located on the left and right sides of the frame 1. In this embodiment, the shovel arm 4 is a main arm located in the middle of the frame, and other structures connected to the shovel arm 4 in embodiment 1 are connected to the main arm.

[0099] The specific embodiment 3 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the retraction of the second pitch cylinder 9 of the slag removal device has an upward pulling effect on the shovel arm 4. In this embodiment, the second pitch cylinder is arranged below the shovel arm, and the pitching motion is achieved by extending outward to lift the shovel arm 4.

[0100] The specific embodiment 4 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the slag removal device includes a second pitching cylinder 9. In this embodiment, the boom is connected to the winch on the frame by a rope, and the pulling force of the winch on the boom achieves boom rotation.

[0101] The specific embodiment 5 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the slider 15 of the slag removal device slides under the action of the propulsion cylinder 7. In this embodiment, the slider 15 achieves linear reciprocating motion through a hydraulic motor and a gear and rack mechanism.

[0102] The specific embodiment 6 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the slider 15 of the slag removal device slides in a groove on the side of the frame, and the groove is an oil groove. In this embodiment, the groove is a recess on both sides of the frame.

[0103] The specific embodiment 7 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the slag removal device chute assembly 2 includes an anti-deviation groove 10. In this embodiment, the anti-deviation groove is not included.

[0104] The specific embodiment 8 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the bottom of the pusher 3 of the slag removal device is a concave arc-shaped plate 22. In this embodiment, the bottom of the pusher is a polygon with a concave center.

[0105] The specific embodiment 9 of the tunneling machine slag removal system provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the pusher 3 of the slag removal device has a slag discharge port on its rear side. In this embodiment, there is no slag discharge port on the rear side of the pusher, and slag discharge is achieved by rotating the pusher at a relatively large angle.

[0106] An embodiment of the tunneling machine slag removal device of the present invention:

[0107] The embodiments of the tunneling machine slag removal device are the slag removal devices described in any of the embodiments 1 to 9 of the tunneling machine slag removal system described above, and will not be described in detail here.

At least the first trailer is connected to the muck-cleaning system described in any of the embodiments 1 to 9 of the tunneling machine muck-cleaning system, which will not be specifically described here.

[0110] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
