Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine testing technology, and in particular, to a slag removal testing device for a spiral inclined shaft TBM. Background Technology

[0002] Inclined tunnel projects, such as pumped-storage power station diversion shafts and mine ventilation shafts, play a crucial role in underground resource development. TBMs (Tunnel Boring Machines), large-scale integrated construction equipment combining tunnel excavation, muck removal, and support functions, are widely used in various horizontal tunnel projects, including railways and water conservancy projects, and are increasingly being applied to inclined tunnels in water conveyance, gas transmission, and mining. The cutterhead, as the core component of the TBM, primarily functions to break rock and remove muck. Spiral inclined shafts, as a common type of inclined tunnel project, require the TBM cutterhead to achieve continuous and efficient muck removal under inclined and turning conditions. Therefore, the rationality of the cutterhead muck removal system design is one of the important factors affecting the TBM tunneling efficiency in spiral inclined shaft projects.

[0003] Building a cutterhead muck discharge test device and conducting experimental simulations to study the cutterhead muck discharge system is a common research method among researchers.

[0044] Please refer to Figure 1 and Figure 2 The preferred embodiment of the present invention provides a spiral inclined shaft TBM slag discharge test device, which includes a support base 100, a telescopic support 200, a connector 300, a base 400, a rotary motor 500, a cutter head 600, an end face box 700, and a slag feeding device 800.

[0045] Multiple telescopic support members 200 are provided. The bottom of the telescopic support member 200 is installed on the support base 100, and the top of the telescopic support member 200 is provided with a telescopic part 210 that can be raised and lowered.

[0046] Multiple connectors 300 are provided, and each connector 300 corresponds to a telescopic support 200. The bottom of each connector 300 is ball-jointed to the upper end of a plurality of telescopic parts 210. Figure 5 As shown, the connector 300 has a ball portion 370 at its bottom and a hemispherical hole at the upper end of the telescopic portion 210. The ball portion 370 is inserted into the hemispherical hole. The telescopic portion 210 has two ball caps 211 at its upper end. The two ball caps 211 are connected to the telescopic portion 210 and fit against the upper half of the ball portion 370, thereby limiting the ball portion 370. Both ball caps 211 have a spherical surface that fits against the ball portion 370. A through hole is formed between the two ball caps 211 to allow the extension portion 360 connected to the upper end of the ball portion 370 to pass through.

[0047] The base 400 has multiple connecting parts 410 at its bottom that are detachably connected to the connecting parts 300. A sliding drive mechanism 420 is mounted on the base 400. The rotary motor 500 has a rotating shaft. The cutter head 600 is drivenly connected to the rotating shaft, and multiple slag passage grooves 610 are arranged around the cutter head 600. The cutter head 600 is located between the rotary motor 500 and the end face box 700. Specifically, the base 400 has a tray at its bottom, and the connecting parts 410 are fixed on the tray 440. During installation, the tray 440 can be installed first, and then the base 400 can be installed on the tray 440, which facilitates installation.

[0048] The end face box 700 is mounted on the side of the cutter head 600 facing away from the rotary motor 500. The bottom of the end face box 700 is slidably mounted on the base 400 to be close to or away from the cutter head 600. The end face box 700 is connected to the sliding drive mechanism 420 and is driven by the sliding drive mechanism 420. The sliding drive mechanism 420 can be a telescopic hydraulic cylinder.

[0049] The slag feeding device 800 is used to transport rock debris into the end face box 700. The end face box 700 is equipped with a slag inlet pipe head 710. The slag feeding device 800 includes a slag container with an outlet at the bottom. The outlet is connected to the slag inlet pipe head 710 via a flexible hose or telescopic pipe, which can accommodate the movement of the end face box 700. The hose or telescopic pipe may be coated with a wear-resistant coating to improve its wear resistance. A flow control valve is installed at the bottom of the slag container to control the rock debris flow rate. This device is used to conduct slag discharge tests, simulating the slag discharge process after a tunneling machine excavates rock and soil into rock debris.

[0050] The slag receiving device 900 is used to receive slag material passing through the slag trough 610.

[0051] This spiral inclined shaft TBM slag removal test device can accurately simulate spiral inclined shaft excavation conditions at different inclination angles by adjusting the telescopic extension of multiple telescopic support members 200. Typically, during spiral inclined shaft excavation, the inclination angle of the tunneling machine includes both the lateral and longitudinal inclination angles. Therefore, at least four telescopic support members 200 are usually set up in a rectangular distribution. The telescopic support members 200 are arranged in a matrix along the lateral and longitudinal directions. Thus, the lateral and longitudinal inclination angles can be adjusted by adjusting the extension of the four telescopic support members 200. By merging the lateral and longitudinal inclination angles, the excavation angle of the tunneling machine when excavating a spiral inclined shaft is simulated.

[0052] This system meets the requirements for simulating the muck removal process of a TBM in applications of inclined tunnel engineering. The rotary motor 500 drives the cutterhead 600 to rotate, and in conjunction with the muck feeding device, conveys rock debris into the end face box 700, simulating the rock-breaking and muck removal process of the TBM cutterhead. The sliding drive mechanism 420 can drive the end face box closer to the cutterhead, simulating the cutting and feeding process of the cutterhead 600. The muck receiving device 900 can effectively receive the muck material passing through the muck chute, facilitating the observation and analysis of the muck removal effect.

[0053] It is understandable that the telescopic support 200 can be an automatically telescopic mechanism, such as a telescopic motor or a telescopic cylinder. Of course, the telescopic support 200 can also be manually adjusted. For example, the telescopic support 200 has a base 220 at its bottom, and the upper end of the base 220 has a movable hole for the telescopic part 210 to be inserted into. The telescopic part 210 can move up and down along the movable hole. Positioning holes can be provided on the periphery of the telescopic part 210, and a limit screw can be threaded onto the periphery of the base 220. The limit screw is embedded in the positioning hole of the telescopic part 210 to fix the position of the telescopic part 210 after height adjustment.

[0054] Reference Figure 3 In some embodiments of the present invention, the telescopic support member 200 is movably mounted on the support base 100, so that the arrangement spacing of the multiple telescopic support members 200 can be changed, thereby adaptively adjusting the position of the telescopic support members 200 to adapt to the distribution of the connecting part 410. The telescopic support members 200 are movable and their arrangement spacing can be changed, allowing the device to flexibly adjust the support point position according to the size, weight distribution of the base 400, and test requirements. This greatly improves the versatility of the device.

[0055] Reference Figure 3In some embodiments of the present invention, at least four telescopic support members 200 are provided. The support base 100 is provided with two longitudinal guide rails 110 extending in the longitudinal direction. A crossbar 120 is longitudinally slidably installed on the two longitudinal guide rails 110. A first transverse guide rail 130 is installed on the crossbar 120. A second transverse guide rail 140 is provided on the support base 100. One telescopic support member 200 is fixedly installed on the support base 100 and laterally aligned with the second transverse guide rail 140. One telescopic support member 200 is laterally slidably installed on the first transverse guide rail 130. One telescopic support member 200 is laterally slidably installed on the second transverse guide rail 140. One telescopic support member 200 is fixedly installed on the crossbar 120 and longitudinally aligned with the telescopic support member 200 fixedly installed on the support base 100. This forms a rectangular distribution of telescopic support members 200, and the length and width of the distribution rectangle can be adjusted. It can be understood that through the support and adjustment at four points, longitudinal tilting and lateral tilting can be achieved, so that it simulates the combined tilting construction conditions of a spiral inclined well. At least four telescopic support members 200, in conjunction with the longitudinal guide rail 110, the crossbar 120, the first transverse guide rail 130, and the second transverse guide rail 140, form a multi-dimensional adjustable support system. The support points are adjusted using the lateral and longitudinal sliding support members. The bottom of each telescopic support member 200 is equipped with a sliding seat that matches the corresponding guide rail (first transverse guide rail 130, second transverse guide rail 140), allowing for position adjustment through sliding and position fixation via set screws. Set screws can also be provided on the crossbar 120 for position fixation.

[0056] Reference Figure 4 and Figure 5In some embodiments of the present invention, the upper end of the connector 300 is provided with a receiving plate 310, and the edge of the receiving plate 310 is provided with an upwardly protruding edge plate 320. The edge plate 320 and the receiving plate 310 define a slot 330. A limiting member 340 and an elastic member 350 are installed in the slot 330. The limiting member 340 is movably installed in the slot 330. The bottom of the connector 410 is provided with an insertion part 411 that is embedded in the slot 330. The insertion part 411 is provided with a limiting hole 412. The limiting member 340 has a limiting state and an unlocking state. In the limiting state, the limiting member 340 is partially embedded in the limiting hole 412 to limit the insertion part 411. In the unlocking state, the limiting member 340 is disengaged from the limiting hole 412. The elastic member 350 abuts against the limiting member 340 to apply an elastic force to the limiting member 340 so that the limiting member 340 in the unlocking state can move toward the limiting state. The insertion part 411 is embedded in the slot 330 to achieve alignment and ensure accurate connection, serving as a positioning limit. The limiting member 340, in its limited state, is partially embedded in the limiting hole 412, limiting the insertion part 411. The limiting member 340 can be moved to the unlocked state to unlock the insertion part 411. The elastic member 350 applies an elastic force to the limiting member 340, ensuring that the limiting member 340 automatically returns to the limited state without additional operation, thus maintaining the limiting member 340 in the limited state. This achieves quick assembly / disassembly and reliable locking of the base 400 and the telescopic support 200. When tilted, because the insertion part 411 is embedded in the slot 330, the weight of the base 400 is transferred to the edge plate 320 and the receiving plate 310. The limiting member 340 only serves to restrict the upward movement of the base 400 so that the insertion part 411 will not disengage from the slot 330. However, the base 400 will not tend to move upward during operation, so the limiting member 340 is basically not subjected to force during operation and stress will not be concentrated on the limiting member 340.

[0057] Reference Figure 4 and Figure 5In some embodiments of the present invention, the upper end face of the receiving plate 310 is provided with a mounting groove 311, the edge plate 320 is provided with a through hole 321, the limiting member 340 is embedded in the base block 341 of the mounting groove 311, and a pressing block 342 is provided on one side of the base block 341. The pressing block 342 passes through the through hole 321 and partially protrudes from the edge plate 320, thereby facilitating manual pressing operation of the pressing block 342 to drive the limiting member 340 to switch to the unlocked state. The base block 341 is provided with an upwardly extending connecting block 343. The upper end of the connecting block 343 is provided with a protrusion 344 protruding towards the limiting hole 412. The inner edge of the upper end of the protrusion 344 is provided with a chamfer 345. The side of the base block 341 facing away from the pressing block 342 is provided with a first positioning protrusion 346. The side wall of the mounting groove 311 opposite to the first positioning protrusion 346 is provided with a second positioning protrusion 312. The elastic element 350 is a compression spring, and the two ends of the compression spring are respectively sleeved on the first positioning protrusion 346 and the second positioning protrusion 312. The mounting groove 311 of the receiving plate 310 provides a stable installation space for the limiting member 340. The push block 342 passes through the through hole 321 to make the unlocking operation more convenient. The chamfer 345 of the protrusion 344 facilitates the insertion part 411 to be smoothly inserted into the slot 330 and automatically triggers the limiting. The center of the insertion part 411 is hollowed out to facilitate the partial entry of the limiting member 340 into the center of the insertion part 411 and avoid structural interference. During operation, the insertion part 411 is pressed down and contacts the chamfer 345. With the action of the chamfer 345, as the insertion part 411 continues to be inserted, the insertion part 411 moves along the chamfer 345 and pushes the protrusion 344 to move until the insertion part 411 is embedded between the protrusion 344 and the edge plate 320 and the protrusion 344 is aligned with the limiting hole 412. Under the action of the compression spring, the protrusion 344 automatically inserts into the limiting hole 412 and reaches the limiting state. The first positioning protrusion 346 and the second positioning protrusion 312 position the compression spring, ensuring stable output of elastic force and preventing the compression spring from shifting and failing.

[0058] Of course, in some other embodiments, the detachable connection between the connecting part 410 and the connecting member 300 can also be achieved by detachable fasteners (such as screws), such as using screws to connect and fix the insert part to the edge plate 320 after the insert part is inserted into the slot 330.

[0059] Reference Figure 2 , Figure 6 , Figure 9 and Figure 10In some embodiments of the present invention, the slag receiving device 900 includes a slag receiving cylinder 910 and a slag collecting container 920; a shovel assembly 620 is detachably installed on the side of the cutter head 600 facing away from the rotary motor 500 at the edge of the slag passage 610, that is, the shovel assembly 620 is installed on the side of the cutter head 600 facing the end face box 700. A slag chute 630 is installed on the side of the cutter head 600 facing the rotary motor 500; the slag chute 630 is an L-shaped plate, including a vertical plate and a horizontal plate. One end of the vertical plate is vertically connected to the cutter head 600, and the other end is vertically connected to the horizontal plate. The horizontal plate blocks the slag passage 610. When the vertical plate and the horizontal plate rotate, they catch the rock slag. When the slag chute 630 is near the vertical position, the rock slag will slide down from the bottom. A rear cover plate 640 is fixedly installed on the side of the cutter head 600 facing the rotary motor 500. The slag receiving cylinder 910 is fixedly installed on the base 400 and located at the center of the side of the cutter head 600 facing the rotary motor 500. Slag chute plates 630 are arranged around the slag receiving cylinder 910. The upper end of the slag receiving cylinder 910 is provided with a slag receiving port 911 to receive the slag material flowing down from the slag chute plates 630. The slag collection container 920 is installed inside the base 400. The lower end of the slag receiving cylinder 910 is provided with a guide chute 912 that extends inclined towards the slag collection container 920 to guide the slag material entering the slag receiving cylinder 910 into the slag collection container 920. The shovel assembly 620 of the slag receiving device 900 facilitates the smooth entry of rock cuttings into the slag passage 610. The slag chute 630 guides the cuttings to the slag receiving cylinder 910, and the guide chute 912 precisely guides the cuttings into the slag collection container 920, simulating the entire process of slag discharge, slag guidance, and slag collection from the TBM cutterhead. The rear cover 640 prevents cuttings from splashing, and the cooperation between the slag receiving cylinder 910 and the slag collection container 920 facilitates the collection and metering analysis of the cuttings. This provides a basis for studying the flow law of cuttings and optimizing the structure of the slag passage 610.

[0060] Reference Figure 6 In some embodiments of the present invention, the bottom of the rear cover plate 640 is provided with a clearance opening 641 for the slag collection container 920 to pass through. The clearance opening 641 at the bottom of the rear cover plate 640 provides a convenient channel for the placement and removal of the slag collection container 920, so that the rear cover plate 640 does not affect the guide chute 912 from guiding the rock debris to the slag collection container 920. The base 400 is provided with a pull-out groove for the slag collection container 920 to be movable and pulled out, so as to facilitate the removal of the slag collection container 920.

[0061] Reference Figure 7 and Figure 8In some embodiments of the present invention, a rotating shaft 650 is provided at the center of the cutter head 600, and an end plate 913 is provided at the end of the slag receiving cylinder 910 facing away from the cutter head 600. A through-shaft cylinder 914 is provided at the center of the side of the end plate 913 facing the cutter head 600, and the through-shaft cylinder 914 and the slag receiving cylinder 910 form a slag chute 915. The rotating shaft 650 passes through the through-shaft cylinder 914, and an opening 916 is provided at the bottom of the end plate 913. A guide chute 912 is connected to the bottom edge of the opening 916. The rotating shaft 650 of the cutter head 600 passes through the through-shaft cylinder 914, so that the rotating shaft 650 and the slag receiving cylinder 910 do not interfere with each other. The slag chute 915 ensures smooth flow of slag, so that the slag chute and the rotating shaft 650 do not interfere with each other. Due to the shielding of the through-shaft cylinder 914, the slag is prevented from contacting the rotating shaft 650 and affecting the rotation of the rotating shaft 650. The end of the rotating shaft and the cutter head 600 can be fixed by fasteners or welding. The end face of the slag receiving cylinder 910 fits against the side of the cutter head 600, reducing the amount of slag entering the slag receiving cylinder 910 through this gap. The opening 916 of the end plate 913 cooperates with the guide chute 912 to ensure that the slag in the slag receiving cylinder 910 can be guided into the slag collection container 920.
