Description

Technical Field

[0001] This invention relates to the field of vertical shaft tunneling equipment technology, specifically to a slag chute platform and slag removal method for a vertical shaft tunneling machine. Background Technology

[0002] A shaft tunneling machine is a large engineering equipment used for excavating underground shafts. During its operation, it generates a large amount of slag, which needs to be discharged in a timely manner. The supporting system behind the tunneling machine is usually equipped with a shotcrete platform and a slag chute platform. The shotcrete platform is located above for shotcrete support of the shaft wall, and the slag chute platform is located below to receive and discharge the slag falling from the shotcrete platform. The two form a working system arranged in layers.

[0003] However, in the actual application of existing shaft boring machines, the slag falling from the sprayed concrete platform contains cement mixtures and rebound material. These materials are prone to solidification and caking when stationary. If the slag does not flow smoothly or stagnates on the slag chute, the cement component will gradually solidify, causing the slag to solidify with the platform surface, the accumulation layer to continuously thicken, and eventually block the slag chute. Once a blockage occurs, the machine must be stopped for manual cleaning, which seriously affects the continuous operation efficiency of shaft boring. Summary of the Invention

[0004] To address the technical problems in the prior art, this invention provides a slag chute platform and slag removal method for a vertical shaft tunneling machine, aiming to solve the problem in the prior art where slag material solidifies and clogging the slag chute channel due to stagnant flow on the slag chute platform.

[0005] The technical solution of the present invention is as follows: A muck chute platform for a shaft boring machine includes a work platform, mounting columns, a muck chute, and auxiliary muck chute structures, wherein... The mounting column is fixedly installed in the middle of the workbench, and a slag discharge channel is provided inside the mounting column; The slag chute includes an inverted conical trough body, a manifold, a slag baffle, a manifold plate, and a column; The trough is located on the top of the workbench. A clearance channel is provided at the bottom of the trough corresponding to the mounting column. A sluice is provided on the side wall of the trough corresponding to the slag discharge channel. The sluice pipe is connected between the bottom of the sluice and the slag discharge channel to guide the slag in the sluice to the slag discharge channel. The slag baffle is located on the periphery of the clearance channel, and the confluence plate is located at the connection between the slag baffle and the trough. The confluence plate and the slag baffle are inclined toward the confluence trough. The columns include multiple columns, which are evenly fixed between the bottom of the tank and the workbench; The auxiliary slag discharge structure is installed on the tank and the manifold plate to assist in slag discharge.

[0006] Optionally, the auxiliary slag chute structure includes a water spray pipe; The water spray pipes are arranged in an arc shape on the top periphery of the tank and are connected to the external water system for breaking up arches and reducing dust.

[0007] Optionally, the auxiliary slag chute structure may further include a vibration motor; The vibration motor includes at least one motor, which is fixedly installed on the back of the tank body, corresponding to the area where the manifold is located, and is used to generate vibration to assist in slag discharge.

[0008] Optionally, the auxiliary slag chute structure may further include arch-breaking ribs; The arch-breaking rib is located on the upper surface of the confluence plate. The arch-breaking rib extends along the confluence direction and fits the shape of the confluence plate. It is used to reduce the contact area between the slag and the confluence plate and to generate shear disturbance to the slag when the vibration motor is started.

[0009] Optionally, the manifold is provided with a cleaning port for cleaning when the manifold becomes blocked.

[0010] Optionally, a slag chute platform for a shaft boring machine may further include an anti-torsion device, which includes an anti-torsion cylinder; The anti-torsion cylinders include multiple cylinders arranged in a ring array around the outer edge of the worktable. The anti-torsion cylinders are used to drive the piston rod to extend outward and brace against the shaft wall to limit the circumferential rotation of the worktable.

[0011] Optionally, the anti-torsion device may further include an anti-slip support plate; The anti-slip support plate is located at the end of the piston rod of the anti-torsion cylinder, and the anti-slip support plate has anti-slip texture on the side facing the shaft wall.

[0012] Optionally, a muck chute platform for a shaft boring machine further includes at least one set of telescopic baffles, each set of telescopic baffles including a mounting frame, a plate body, and a telescopic hydraulic cylinder, wherein, The mounting bracket is installed on the outer edge of the tank, and a clearance opening is provided on the outer edge of the tank corresponding to the mounting bracket. The plate is slidably mounted on the mounting frame, and its sliding direction is towards or away from the center of the groove. The telescopic cylinder is fixedly mounted on the mounting frame and driven to the plate body, and is used to drive the plate body to extend to close the clearance opening or retract to open the clearance opening.

[0013] Optionally, a shaft boring machine chute platform may also include at least one set of cover plates; The cover plate is placed on the workbench and is correspondingly arranged with the plate body, and is used to connect or disconnect the clearance opening when needed.

[0014] The present invention also provides a method for removing slag from a shaft tunneling machine chute platform. Based on the aforementioned shaft tunneling machine chute platform, the slag removal method includes: S1: The slag falling from the upper spray mixing platform enters the inverted cone-shaped tank; S2: The water spray pipe continuously sprays water, forming a water film on the tank and the manifold, while the vibration motor continues to run. S3: The slag material flows along the confluence direction guided by the arch-breaking ribs, and is simultaneously subjected to shearing disturbance by the arch-breaking ribs; S4: The slag baffle prevents slag from falling into the clearance channel and guides the slag to the confluence plate; S5: Under the combined guidance of the inclined confluence plate and the slag baffle, the slag material concentrates into the confluence channel; S6: The slag material enters the slag discharge channel inside the installation column through the slag collection trough and slag collection pipe to complete the slag discharge.

[0015] Compared with the prior art, the slag chute platform and slag removal method for a vertical shaft tunneling machine provided by the present invention have the following beneficial effects: (1) By adopting an inverted conical tank, a clearance channel at the bottom of the tank, a slag baffle on the periphery of the clearance channel, a confluence plate at the connection between the slag baffle and the tank, and a confluence pipe connecting the confluence trough and the slag discharge channel, the slag material is automatically concentrated in the confluence trough along the inclined confluence plate and slag baffle by gravity, and is discharged through the confluence pipe into the slag discharge channel, thus avoiding the stagnation of slag material on the slag chute platform and effectively preventing the problem of slag material blocking the channel due to solidification and caking.

[0016] (2) By setting water spray pipes in an arc shape distributed around the top of the tank and continuously spraying water, a water film is formed on the tank and the confluence plate, which reduces the adhesion between the slag and the contact surface. At the same time, a vibrating motor is set to start continuously, and in conjunction with the arch-breaking ribs that extend along the confluence direction and fit the shape of the confluence plate, a continuous shearing disturbance and guiding effect is generated on the slag, so that the slag always remains in a flowing state, further enhancing the smoothness of slag discharge and avoiding blockage and shutdown caused by slag accumulation.

[0017] (3) By setting multiple anti-torsion cylinders distributed in a ring array around the outer edge of the workbench and anti-slip support plates with anti-slip texture, the piston rod can be driven to extend outward and support the vertical shaft wall when the equipment is working, which effectively restricts the circumferential rotation of the workbench and ensures the positional stability of the slag chute platform when the spray mixing platform is working; at the same time, by setting telescopic baffles and covers, the clearance opening can be opened or closed as needed, realizing flexible control of the material conveying channel between the workbench and the top of the tank and between the top and bottom of the device.

[0026] Please see Figures 1-7 The present invention provides a slag chute platform for a vertical shaft tunneling machine, including a work platform 1, a mounting column 2, a slag chute 3, and an auxiliary slag chute structure 4.

[0027] like Figures 1-2 , Figures 4-5As shown, the mounting column 2 is fixedly installed in the middle of the workbench 1, and a slag discharge channel 201 is provided inside the mounting column 2; the slag chute 3 includes an inverted conical trough 31, a manifold pipe 32, a slag discharge baffle 33, a manifold plate 34, and a column 35; the trough 31 is located at the top of the workbench 1, and a clearance channel 301 is opened at the bottom of the trough 31 corresponding to the mounting column 2. A manifold trough 302 is opened on the side wall of the trough 31 corresponding to the slag discharge channel 201. The manifold pipe 32 is connected to the bottom of the manifold trough 302 and the slag discharge channel. Between the channels 201, the slag in the confluence channel 302 is guided to the slag discharge channel 201; the slag baffle 33 is located on the periphery of the clearance channel 301, and the confluence plate 34 is located at the connection between the slag baffle 33 and the tank body 31. The confluence plate 34 and the slag baffle 33 are inclined toward the confluence channel 302; multiple columns 35 are evenly fixed between the bottom of the tank body 31 and the workbench 1; the auxiliary slag discharge structure 4 is located on the tank body 31 and the confluence plate 34 to assist in slag discharge.

[0028] Specifically, the inverted conical trough 31's aggregation effect allows the slag to naturally concentrate towards the bottom of the trough 31 under gravity; the clearance channel 301 facilitates the passage of the upper mixing platform when it is installed on the mounting column 2, while the slag baffle 33 surrounds the clearance channel 301, effectively preventing slag from falling into it; guided by the inclined slag baffle 33 and the confluence plate 34, the slag automatically flows towards the confluence trough 302, such as... Figure 5 The slag enters the slag discharge channel 201 through the manifold 32 and is discharged. The entire slag discharge process is completed by gravity, without the need for additional power. The structure is simple and reliable. With the auxiliary slag chute structure 4, the slag material is effectively prevented from solidifying and caking on the slag chute platform due to stagnation.

[0029] In some embodiments, such as Figure 2 , Figure 4 As shown, the auxiliary slag chute structure 4 includes a water spray pipe 41; the water spray pipe 41 is distributed in an arc shape on the outer periphery of the top of the tank 31 and is connected to the external water system for breaking the arch and reducing dust.

[0030] Specifically, in this embodiment, the water spray pipe 41 is distributed in an arc shape on the top periphery of the tank 31, covering the entire circumferential area of ​​the tank 31. The external water system supplies water to the water spray pipe 41. After the water is sprayed out from the water spray pipe 41, on the one hand, a water film is formed on the surface of the tank 31 and the manifold 34, reducing the adhesion between the slag and the contact surface, making the slag easier to slide off. On the other hand, the water flow impacts and disturbs the slag, destroying the arched structure that the slag may form and preventing blockage. At the same time, the water spray also has a dust suppression effect, improving the downhole working environment. The continuous water spraying from the water spray pipe 41 and the gravity slag discharge work together to keep the slag in good fluidity.

[0031] In some embodiments, such as Figure 7As shown, the auxiliary slag discharge structure 4 also includes a vibration motor 42; at least one vibration motor 42 is included, and the vibration motor 42 is fixedly installed on the back of the tank 31, corresponding to the area where the manifold 34 is located, and is used to generate vibration to assist in slag discharge.

[0032] Specifically, in this embodiment, the vibration motor 42 is fixedly installed on the back of the tank 31 in the area corresponding to the manifold 34. After the vibration motor 42 is started, it generates high-frequency micro-amplitude vibration. This vibration is transmitted to the slag through the tank 31 and the manifold 34, which destroys the friction and adhesion between the slag particles, and the slag is in an "activated" state with significantly enhanced fluidity. The vibration motor 42 continues to start, forming a synergy with the water spraying effect of the water spray pipe 41: water spraying reduces adhesion, and vibration destroys the bridging structure. The two work together to ensure that the slag does not stagnate in the area of ​​the manifold 34 due to compression or adhesion, thereby avoiding solidification and caking.

[0033] In some embodiments, such as Figures 4-6 As shown, the auxiliary slag chute structure 4 also includes an arch-breaking rib 43; the arch-breaking rib 43 is provided on the upper surface of the confluence plate 34, the arch-breaking rib 43 extends along the confluence direction and fits the shape of the confluence plate 34, in order to reduce the contact area between the slag and the confluence plate 34, and generate shear disturbance to the slag when the vibration motor 42 is started.

[0034] Specifically, in this embodiment, the arch-breaking rib 43 is disposed on the upper surface of the confluence plate 34, extends along the confluence direction, and fits the shape of the confluence plate 34. The protruding structure of the arch-breaking rib 43 significantly reduces the actual contact area between the slag and the confluence plate 34, reducing the adhesion force. When the vibration motor 42 is started, the edges of the arch-breaking rib 43 generate concentrated shear disturbance on the slag, effectively destroying the adhesion layer between the slag and the arch structure that may be formed. At the same time, the arch-breaking rib 43 extends along the confluence direction, guiding the flow of the slag, so that the slag flows orderly towards the confluence channel 302 in a predetermined direction. The arch-breaking rib 43, the vibration motor 42, and the water spray pipe 41 work together to form a complete anti-clogging system of reducing adhesion, disturbance, and guidance.

[0035] In some embodiments, such as Figure 5 As shown, a cleaning port 321 is provided on the manifold 32 for cleaning when the manifold 32 becomes blocked.

[0036] Specifically, the manifold 32 is connected between the bottom of the manifold 302 and the slag discharge channel 201, and is the key channel for slag discharge. During long-term use, if a small amount of slag accumulates or clogs in the manifold 32, it can be quickly cleaned through the slag cleaning port 321 opened on the manifold 32 without disassembling the manifold 32 or stopping the machine for maintenance, which greatly reduces the maintenance difficulty and downtime, and improves the continuous operation capability of the equipment. When not in use, the slag cleaning port 321 is sealed with a sealing plate to ensure the normal operation of the manifold 32.

[0037] In some embodiments, such as Figures 1-3 As shown, a slag chute platform for a vertical shaft tunneling machine also includes an anti-torsion device 5, which includes an anti-torsion cylinder 51. The anti-torsion cylinder 51 includes multiple cylinders arranged in a ring array on the outer edge of the worktable 1. The anti-torsion cylinder 51 is used to drive the piston rod to extend outward and brace against the vertical shaft wall to limit the circumferential rotation of the worktable 1.

[0038] Specifically, in this embodiment, multiple anti-torsion cylinders 51 are arranged in a circular array along the outer edge of the workbench 1. When the equipment is working, the anti-torsion cylinders 51 drive the piston rod to extend outward, so that the end of the piston rod is braced against the vertical shaft wall. Since multiple anti-torsion cylinders 51 are evenly arranged circumferentially, they work together to form a circumferential constraint, which effectively restricts the rotational degree of freedom of the workbench 1. Even if the upper spray mixing platform generates a rotational torque when it is working, the slag chute platform will not rotate with it, ensuring the alignment accuracy of the slag discharge channel and the confluence channel 302. The anti-torsion cylinders 51 are self-locking hydraulic cylinders with mechanical self-locking function.

[0039] In some embodiments, such as Figure 3 As shown, the anti-torsion device 5 also includes an anti-slip support plate 52; the anti-slip support plate 52 is located at the end of the piston rod of the anti-torsion cylinder 51, and the side of the anti-slip support plate 52 facing the shaft wall is provided with anti-slip texture.

[0040] Specifically, in this embodiment, the anti-slip support plate 52 is fixed to the end of the piston rod of the anti-torsion cylinder 51, and anti-slip texture is provided on the side facing the shaft wall. When the anti-torsion cylinder 51 drives the piston rod to extend, the anti-slip support plate 52 presses against the shaft wall, and the anti-slip texture increases the coefficient of friction between the anti-slip plate and the shaft wall, preventing relative sliding when subjected to force. Even if the surface of the shaft wall is uneven or has mud and water, the anti-slip texture can still provide reliable friction to ensure the locking effect of the anti-torsion device 5. The anti-slip support plate 52 can be made of wear-resistant steel plate, and the anti-slip texture can be a mesh, stripe, or dotted uneven structure.

[0041] In some embodiments, such as Figure 7As shown, a chuting platform for a vertical shaft tunneling machine also includes at least one set of telescopic baffles 6. Each set of telescopic baffles 6 includes a mounting frame 61, a plate 62, and a telescopic cylinder 63. The mounting frame 61 is located at the outer edge of the trough 31, and a clearance opening 303 is provided on the outer periphery of the trough 31 corresponding to the mounting frame 61. The plate 62 is slidably mounted on the mounting frame 61, and its sliding direction is towards or away from the center of the trough 31. The telescopic cylinder 63 is fixedly mounted on the mounting frame 61 and drivenly connected to the plate 62, and is used to drive the plate 62 to extend to close the clearance opening 303 or retract to open the clearance opening 303.

[0042] Specifically, in this embodiment, the telescopic baffle 6 is used to connect or separate the workbench 1 from the upper part of the tank 31. When materials or tools need to be transported from the workbench 1 to the upper spray mixing platform, the telescopic cylinder 63 drives the plate 62 to retract, opening the clearance port 303 to form a vertical channel. When the transport is completed and slag discharge is required, the telescopic cylinder 63 drives the plate 62 to extend, closing the clearance port 303 to prevent slag from falling from the clearance port 303. The sliding direction of the plate 62 is towards or away from the center of the tank 31, so that when the plate 62 extends, it extends into the tank 31 to close the clearance port 303; when it retracts, it exits outward to make way. It is worth noting that, in the specific setting, the inner side of the plate 62 and the inner wall of the tank 31 are on the same curved surface to avoid slag accumulation when the clearance port 303 is closed.

[0043] In some embodiments, such as Figure 2 , Figure 4 As shown, a slag chute platform for a vertical shaft tunneling machine also includes at least one set of cover plates 7; the cover plates 7 are disposed on the workbench 1 and are correspondingly disposed with the plate body 62, and are used to connect or disconnect the clearance opening 303 when needed.

[0044] Specifically, in this embodiment, the cover plate 7 is set on the workbench 1, corresponding to the position of the plate body 62; after the plate body 62 of the telescopic baffle 6 retracts and opens the clearance opening 303, the channel between the workbench 1 and the top of the trough 31 is opened; at this time, if it is necessary to realize through-transport between the top and bottom of the device, the cover plate 7 can be further opened, so that materials or tools can be transported from the top of the device through the clearance opening 303 and the opening on the workbench 1 to the bottom of the device; conversely, closing the cover plate 7 will block the channel; the cover plate 7 and the telescopic baffle 6 form a two-level channel control: the telescopic baffle 6 controls the connection between the workbench 1 and the top of the trough 31, and the cover plate 7 controls the opening on the top of the workbench 1. The two work together to flexibly realize the material transportation of different ranges.

[0045] Please see Figure 8 The present invention also provides a method for removing slag from a shaft tunneling machine chute platform. Based on the aforementioned shaft tunneling machine chute platform, the slag removal method includes: S1: The slag falling from the upper spray mixing platform enters the inverted cone-shaped tank; S2: The water spray pipe continuously sprays water, forming a water film on the tank and the manifold, while the vibration motor continues to run. S3: The slag material flows along the confluence direction guided by the arch-breaking ribs, and is simultaneously subjected to shearing disturbance by the arch-breaking ribs; S4: The slag baffle prevents slag from falling into the clearance channel and guides the slag to the confluence plate; S5: Under the combined guidance of the inclined confluence plate and the slag baffle, the slag material concentrates into the confluence channel; S6: The slag material enters the slag discharge channel inside the installation column through the slag collection trough and slag collection pipe to complete the slag discharge.

[0046] Specifically, firstly, the slag falling from the upper spray mixing platform enters the inverted conical tank 31. The inverted conical structure causes the slag to naturally concentrate at the bottom of the tank 31. During the slag discharge process, the water spray pipe 41 continuously sprays water, forming a water film on the surface of the tank 31 and the manifold 34. This water film significantly reduces the adhesion between the slag and the contact surface, while the water flow impact disturbs the slag. At the same time, the vibration motor 42 continuously starts, generating high-frequency micro-vibration and transmitting it to the tank 31 and the manifold 34. During the flow of slag, the arch-breaking ribs 43, which extend along the confluence direction and conform to the shape of the confluence plate 34, guide the slag, causing it to flow in an orderly manner in the predetermined direction. At the same time, the edges of the arch-breaking ribs 43 generate concentrated shear disturbances on the slag under vibration, effectively destroying the adhesion layer between the slag and any arched structures that may be formed. The slag baffle 33 prevents the slag from falling into the clearance channel 301 and guides the slag to the confluence plate 34, preventing the slag from falling from the clearance channel 301. Subsequently, under the joint guidance of the inclined confluence plate 34 and the slag baffle 33, the slag concentrates in the confluence trough 302, and gravity causes the slag to slide down automatically without additional power. Finally, the slag enters the slag discharge channel 201 in the installation column 2 through the confluence pipe 32 at the bottom of the confluence trough 302, completing the entire slag discharge process.

[0047] In the above method, water spraying, vibration, and arch-breaking ribs work together to ensure that the slag maintains a good flow state throughout the entire process from entering the tank 31 to being discharged, thus preventing the slag from solidifying and caking due to stagnation. The entire slag discharge process is completed by gravity and continuous auxiliary means, which is simple in structure, low in energy consumption, and has strong continuous operation capability, effectively solving the problem of shutdown and cleaning caused by slag blockage in the existing technology.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
