Description

Technical Field

[0001] This application relates to the field of tunnel boring machines, and more particularly to a vibration-damping adjustable support. Background Technology

[0002] In earth pressure balance tunnel boring machine (TBM) construction in water-rich strata, the soil pressure inside the screw conveyor is difficult to control, often leading to sudden situations such as blowouts. To solve this problem, TBM manufacturers generally use a double-stage screw conveyor solution, extending the screw conveyor cylinder section to reduce the pressure at the muck outlet inside the cylinder section and prevent blowouts.

[0003] In a two-stage screw conveyor, the primary screw conveyor is typically fixed using a front flange and a middle tie rod. The front of the secondary screw conveyor is connected to the tail of the primary screw conveyor using a spherical bearing. The rear fixing methods for the secondary screw conveyor vary, including rollers and chutes, sliding supports, and hangers, each with its own advantages and disadvantages, but none can meet all performance requirements. However, existing secondary screw conveyor rear fixing methods have several problems, including: 1) displacement deviation when adapting to large-stroke extension and retraction of the shield or articulated section; 2) inability to meet the extension and retraction requirements of the primary screw conveyor; 3) vibration generated by the screw conveyor drive affects the entire conveying process; and 4) relative displacement between the screw conveyor's slag outlet and the belt conveyor's slag receiving section during small-radius curve tunneling, which can easily lead to slag leakage or interference. Utility Model Content

[0004] This application provides a vibration-damping adjustable support, which effectively solves the problem of limited vertical traffic on traditional steel truss platforms, which cannot meet the vertical traffic needs between multi-level platforms.

[0005] The present invention solves the above-mentioned technical problems mainly through the following technical solutions: A vibration-damping adjustable support is provided, comprising a load-bearing support member, a roller support seat, and a support mechanism. The load-bearing support member is a hollow component with an open top. The roller support seat is disposed within the load-bearing support member, and a first damping structure is installed at its bottom. A height adjustment mechanism is provided between the first damping structure and the bottom wall of the load-bearing support member. A second damping structure is provided between the inner walls of both ends of the load-bearing support member in a first direction and the corresponding ends of the roller support seat. A lateral displacement adjustment mechanism is provided within the load-bearing support member and is connected to the roller support seat for adjusting the lateral displacement of the roller support seat in a second direction. The first and second directions are both on the same horizontal plane and perpendicular to each other. The support mechanism is rotatably mounted on the top of the roller support seat and can swing up and down.

[0006] Furthermore, the support mechanism includes two sets of roller groups, each of which is rotatably mounted on the top of the roller support seat and can swing up and down. The two sets of roller groups are spaced apart and symmetrically distributed along the second direction. Each set of roller groups has a rotatable roller, and the upper part of the two sets of rollers forms a symmetrical V-shaped support surface in the second direction.

[0007] Furthermore, it also includes an anti-rotation structure, which is disposed on the top of the roller support seat and located between the two sets of rollers. The anti-rotation structure includes two sets of mechanical limiting blocks, which are symmetrically distributed in the second direction, and the ends of the two sets that are close to each other are both provided as spherical or arc surfaces. Each set of mechanical limiting blocks has a set of spring-loaded flexible limiting blocks at both ends in the first direction.

[0008] Furthermore, the roller assembly includes an open roller box at the top and at least two rollers. The rollers are disposed in the roller box and their two ends are rotatably connected to the opposite side walls of the roller box via shafts. The top of the rollers protrudes outside the roller box.

[0009] Furthermore, the top of the roller support seat is symmetrically provided with two V-shaped inclined surfaces in the second direction. Each inclined surface is provided with a pair of ear plates. The roller box is placed between the pair of ear plates, and the middle parts of the opposite side walls of the roller box are rotatably connected to the pair of ear plates through a rotating shaft.

[0010] Furthermore, the first damping structure includes multiple sets of rubber dampers spaced apart.

[0011] Furthermore, the height adjustment mechanism includes multiple height adjustment pads, which are arranged one-to-one between each group of rubber shock absorbers and the bottom wall of the load-bearing support.

[0012] Furthermore, the top of the height adjustment pad is provided with a T-shaped groove, and the lower end of the rubber shock absorber is provided with a T-shaped plate, which is inserted into the T-shaped groove.

[0013] Furthermore, it also includes a lifting mechanism, which is installed at the bottom of the roller support base and is used to cooperate with the bottom wall of the bearing support member to lift the roller support base.

[0014] Furthermore, the lateral displacement adjustment mechanism includes two sets of telescopic pushing devices, which are respectively mounted on the inner walls of both sides of the bearing support member in the second direction, and the driving ends of the two sets of telescopic pushing devices are respectively in contact with the side ends of the roller support seat in the second direction.

[0015] The beneficial effects of the construction integration platform of this utility model are as follows: The secondary screw conveyor section is supported on two sets of roller supports, which can accommodate the sliding and swaying of the section during the telescoping of the shield or articulated extension and retraction, as well as the telescoping of the primary screw conveyor, and distribute the load. The first damping structure under the roller support seat and the second damping structure on the side can reduce the impact of vibration. The lateral displacement adjustment of the roller support seat can adjust the relative position of the screw conveyor slag outlet and the belt conveyor slag receiving section during small curve radius turning tunneling, avoiding slag leakage or interference.

In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0023] Please see Figures 1 to 9 This application provides a vibration-damping adjustable support, which can be used as a support for the secondary screw conveyor (represented by A in the figure) of a tunnel boring machine. Specifically, the lower surface of the secondary screw conveyor A's cylindrical section is supported on the top of the vibration-damping adjustable support and can move relative to the support in a first direction. During use, the vibration-damping adjustable support can adapt to the longitudinal displacement changes and vertical swing angle changes of the secondary screw conveyor A. It also provides good vibration damping for the overall operation of the secondary screw conveyor A. Furthermore, when the tunnel boring machine is excavating on a curve with a very small radius, the tail of the secondary screw conveyor A's cylindrical section will experience a large horizontal offset. The support can adjust the horizontal position of the support surface to match the horizontal offset of the tail of the secondary screw conveyor A's cylindrical section, avoiding slag leakage or interference with structural pipelines. In addition, it can meet the condition of adjusting the height of the secondary screw conveyor A when the gap between the slag outlet of the secondary screw conveyor A and the material receiving section of the belt conveyor is too small.

[0024] Specifically, the vibration-damping adjustable support in this embodiment mainly includes core components such as a load-bearing support 1, a roller support 2, and a support mechanism.

[0025] Among them, the load-bearing support 1 is a hollow component with an open upper part and a flat inner bottom wall.

[0026] The roller support 2 is integrally set inside the bearing support 1. The support mechanism is rotatably mounted on the top of the roller support 2. The cylinder section of the secondary screw conveyor A is in contact with the upper part of the support mechanism. During the longitudinal displacement of the secondary screw conveyor A, the support mechanism and the cylinder section of the secondary screw conveyor A always remain in contact and swing up and down accordingly.

[0027] A first damping structure 4 is installed at the bottom of the roller support 2, and a height adjustment mechanism 5 is provided between the lower end of the first damping structure 4 and the bottom wall of the bearing support 1. This height adjustment mechanism 5 allows for adjustment of the height of the roller support 2, thereby adjusting the height of the secondary screw conveyor A. The first damping structure 4 effectively absorbs vibration energy during the operation of the secondary screw conveyor A, reducing the impact of vibration on its operation.

[0028] Meanwhile, a second damping structure 6 is also provided between the inner walls of both ends of the bearing support member 1 in the first direction and the corresponding ends of the roller support seat 2. The second damping structure 6 can also absorb the vibration generated in the first direction.

[0029] In addition, a lateral displacement adjustment mechanism is provided in the bearing support 1. This lateral displacement adjustment mechanism is connected and cooperates with the roller support 2. It is mainly used to adjust the lateral displacement of the roller support 2 in the second direction. The horizontal relative position of the tail of the A section of the secondary screw conveyor is adjusted by adjusting the displacement in this direction, so as to avoid possible slag leakage or structural pipeline interference.

[0030] In some embodiments, the support mechanism includes two sets of roller groups 3, which are rotatably mounted on the top of the roller support seat 2 and can swing up and down. The two sets of roller groups 3 are spaced apart and symmetrically distributed along the second direction. Each set of roller groups 3 has a rotatable roller 31. The upper part of the two sets of rollers 31 forms a symmetrical V-shaped support surface in the second direction. The lower part of the secondary screw conveyor A is accommodated on the upper part of the support surface. When the secondary screw conveyor A undergoes longitudinal displacement, the roller 31 rolls relative to the secondary screw conveyor A and can rotate with the longitudinal displacement of the secondary screw conveyor A in the first direction. Furthermore, since the roller groups 3 can swing up and down, when the secondary screw conveyor A undergoes longitudinal displacement and swings up and down, the two sets of roller groups 3 can swing up and down with the secondary screw conveyor A, ensuring that the roller 31 always maintains contact with the secondary screw conveyor A and provides stable support for the secondary screw conveyor A.

[0031] The following describes the vibration-damping adjustable support of this embodiment in detail with reference to several application scenarios: Application Scenario 1: When the tunnel boring machine (TBM) expands and contracts the shield body B or its articulated expansion and contraction, and the primary screw conveyor C expands and contracts, the secondary screw conveyor A will experience longitudinal displacement Δz and vertical oscillation a°, as follows: Figure 3 As shown, the two roller sets 3 on the vibration-damping adjustable support D swing accordingly, always keeping the roller 31 in contact with the cylinder section of the secondary screw conveyor A.

[0032] Application Scenario 2: When the tunnel boring machine is excavating on a curve with an extremely small radius, the tail end of the secondary screw conveyor A may experience significant horizontal displacement, potentially leading to slag leakage or interference with structural pipelines. Figure 4 and Figure 5 As shown, the lateral displacement adjustment mechanism can adjust the movement of the roller support 2 in the second direction, thereby adjusting the horizontal offset Δx of the roller group 3 and the roller support 2, and thus adjusting the relative position of the tail section of the secondary screw conveyor A.

[0033] Application Scenario 3: When the vertical clearance between the cylinder section of the secondary screw conveyor A and the assembly machine is too small, or the clearance between the slag outlet of the secondary screw conveyor A and the receiving section of the belt conveyor E is too small, it is necessary to adjust the height of the secondary screw conveyor A. Figure 9 As shown, the height of the roller support seat 2 can be adjusted by using the height adjustment mechanism 5, which means that the vertical offset Δy of the A section of the secondary screw conveyor can be adjusted.

[0034] In other application scenarios, when a tunnel boring machine (TBM) is excavating along a curve, the articulated system causes the shield body B to bend horizontally, and simultaneously, the secondary screw conveyor A also bends horizontally relative to the primary screw conveyor C, such as... Figure 6 , Figure 7 , Figure 8 As shown, at this time, the secondary screw conveyor A section rotates horizontally by b° relative to the roller support 2, and the roller group 3 rotates asymmetrically with the secondary screw conveyor A section. Therefore, an anti-rotation structure 9 is set at the top of the roller support 2 corresponding to the position between the two roller groups 3. Specifically, the anti-rotation structure 9 includes two sets of mechanical limiting blocks 91, which are symmetrically distributed in the second direction, and the ends of the two blocks that are close to each other are both set as spherical or arc-shaped surfaces. Each set of mechanical limiting blocks 91 has a set of spring-loaded flexible limiting blocks 92 at both ends in the first direction. The anti-torsion plate below the secondary screw conveyor A section is stuck between the two sets of mechanical limiting blocks 91 and multiple sets of flexible limiting blocks 92. Since the side of the mechanical limiting block 91 that contacts it is a spherical or arc-shaped surface, it does not restrict the swing of the secondary screw conveyor A section in the horizontal direction, but it restricts the rotation of the section. At the same time, when the anti-torsion plate touches the flexible limiting block 92, it can also play a buffering and shock-absorbing effect. In addition, the springback characteristics of the flexible limiting block 92 can also be used to apply a springback force to the anti-torsion plate. This springback force acts on the cylinder section, which can make the cylinder section automatically align.

[0035] In this embodiment, the flexible limiting block 92 is made of rubber. During use, the anti-torsion plate at the bottom of the A section of the secondary screw conveyor is located between the flexible limiting blocks 92. The flexible limiting blocks 92 distributed on both sides of the anti-torsion plate are also designed with a spherical surface or a circular arc cross-section at their closest ends.

[0036] In some embodiments, the top of the roller support 2 has a V-shaped mounting surface in the longitudinal section of the second direction. Two sets of rollers 3 are symmetrically distributed along the second direction and are rotatably mounted on the inclined surfaces on both sides of the mounting surface. This allows the two sets of rollers 3 to effectively form a V-shaped support surface after being assembled on the mounting surface.

[0037] In some embodiments, the roller assembly 3 includes a roller box 32 and at least two rollers 31. The roller box 32 extends along a first direction, and its bottom wall is arc-shaped (generally resembling a boat shape, with both ends transitioning upwards into an arc). The at least two rollers 31 are spaced apart along the first direction, and the two ends of each roller 31 are rotatably connected to the inner walls of the two sides of the long side of the roller box 32 via shafts. The top of each roller 31 is located above the roller box 32, and the top surfaces of the at least two rollers 31 are in the same plane. The two side walls of the long side of the roller box 32 are rotatably assembled with the mounting surface. The planes on which the tops of the rollers 31 of the two roller assemblies 3 are located respectively constitute two planes of the support surface.

[0038] In some other embodiments, the roller box 32 may also be replaced by a wheel frame with a U-shaped cross-section.

[0039] In some embodiments, the top of the roller support 2 forms a mounting surface, which includes two inclined surfaces that are symmetrically arranged in a V-shape in a second direction. A pair of ear plates 21 are vertically arranged on the inclined surfaces respectively. The roller assembly 3 is placed between the corresponding (pair) of two ear plates 21, and the two sides of the middle part of the roller assembly 3 are rotatably connected to the two ear plates 21 through a rotating shaft, so that the roller assembly 3 can swing up and down relative to the rotating shaft.

[0040] Specifically, the two ear plates 21 are rotatably connected in the middle area of ​​the side wall where the long side of the roller box 32 is located via a pivot.

[0041] Of course, the two ear plates 21 corresponding to each set of rollers 3 can also be replaced with a U-shaped mounting plate. The mounting plate (welded) is fixed on the inclined surface of the mounting surface, the rollers 3 are placed in the mounting plate, and the two sides are rotatably connected to the two sides of the mounting plate through the rotating shaft.

[0042] In some embodiments, the first damping structure 4 employs a rubber damper.

[0043] In other embodiments, multiple sets of rubber shock absorbers are designed and arranged in an array along the first and second directions, or only two sets are provided in the second direction. A height adjustment mechanism 5 is provided between the lower end of the multiple sets of rubber shock absorbers and the bottom wall of the bearing support 1.

[0044] Of course, the first damping structure 4 mentioned above is not limited to rubber dampers, but can be other existing products with damping effects.

[0045] In some embodiments, the height adjustment mechanism 5 includes a height adjustment pad, which is disposed between the lower end of the first shock-absorbing structure 4 and the bottom wall of the bearing support 1. The height of the roller support 2 can be adjusted by replacing the height adjustment pads of different heights.

[0046] Specifically, the height adjustment mechanism 5 may be equipped with multiple height adjustment pads, which are arranged one-to-one between each set of rubber shock absorbers and the bottom wall of the bearing support 1.

[0047] In this embodiment, the height adjustment pad is detachably assembled with the rubber shock absorber, making both easy to disassemble and replace. Details are as follows: The height adjustment pad has a T-slot at its top, and a T-plate adapted to the T-slot is located at the lower end of the rubber shock absorber. The T-plate is inserted into the T-slot along the first direction, and then the two are locked together by the locking assembly. When replacing the height adjustment pad with a different height, first engage the locking assembly, then replace it.

[0048] The locking component can be a bolt. Bolts are provided on both sides of the T-shaped groove opening. The bolts can be tightened to abut against the surface of the T-shaped plate to achieve locking.

[0049] In some embodiments, considering the need to lift the roller support 2 during the replacement of the height adjustment pad so that the height adjustment pad can be easily removed, a lifting mechanism 8 should also be provided. The lifting mechanism 8 is installed at the bottom of the roller support 2. When the height adjustment pad needs to be replaced, the lifting mechanism 8 extends and disengages from the bottom wall of the bearing support 1, so that the roller support 2 is lifted up. Then the height adjustment pad is removed and replaced with a suitable size. After replacement, the lifting mechanism 8 lowers its height, so that the roller support 2 falls down.

[0050] Of course, the aforementioned lifting mechanism 8 can be installed in the middle of the bottom wall of the bearing support 1, with its lifting end facing upwards, and connected to a horizontal lifting plate. When the lifting plate is lifted, it fits against the bottom of the roller support 2 to lift the roller support 2.

[0051] In other embodiments, the height adjustment pad can be designed as a lifting component, which can be a hydraulic jack or other similar device. A carrier plate is set on the top of the lifting component, and the first shock-absorbing structure 4 is installed on the upper part of the carrier plate. The height can be adjusted as needed by lifting with the lifting component, without the need to remove or replace the height adjustment pads of different heights.

[0052] In some embodiments, the lateral displacement adjustment mechanism includes two sets of telescopic pushing devices 71, which are respectively mounted on the inner walls of the bearing support 1 on both sides in the second direction. The driving ends of the two sets of telescopic pushing devices 71 are respectively in contact with the side ends of the roller support 2 on both sides in the second direction. When it is necessary to adjust the lateral displacement of the roller support 2 in the second direction, one set of telescopic pushing devices 71 extends while the other set retracts, which can act on the roller support 2 to change its lateral displacement.

[0053] In some other embodiments, a set of telescopic pushing devices 71 may also be provided, which can be used to adjust the displacement of the roller support 2 by pushing and pulling on one side.

[0054] In this embodiment, the telescopic pushing device 71 adopts a suitable model of hydraulic cylinder, air cylinder, etc. The cylinder body is fixedly connected to the fixed seat on the inner wall of the bearing support 1. The telescopic rod extends toward the corresponding side of the roller support 2, and a push plate is provided at the end of the telescopic end. The push plate is in contact with the corresponding side of the roller support 2.

[0055] In some embodiments, the second damping structure 6 employs vibration-damping rubber pads, with multiple vibration-damping rubber pads spaced apart between the inner walls of both ends of the bearing support member 1 in the first direction and the corresponding ends of the roller support seat 2. The vibration-damping rubber pads are fixed to the inner walls of the corresponding ends of the bearing support member 1 or the end faces of the corresponding ends of the roller support seat 2 by adhesive bonding or screw fixing. The vibration-damping rubber pads are clamped between the bearing support member 1 and the roller support seat 2.

[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0057] The above provides a detailed description of a vibration-damping adjustable support provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
