[0004] In the above scheme, the longitudinal full-length continuous vibration of the second lining vault is achieved, which effectively improves the vibration effect and the construction quality of the second lining vault casting. The conduit used to connect the vibrating rod is a rigid connection as a whole, which can provide stable support for the vibrating rod. However, after the vibrating rod is started, the vibration will be transmitted along the conduit to the support frame, thereby affecting the friction contact between the roller and the conduit and reducing the efficiency of the vibrating rod moving in the concrete. Summary of the invention

[0005] The purpose of the present invention is to provide a method and equipment for vibrating in the length direction of a tunnel lining layer, which can solve the above technical problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The method of vibrating in the length direction of the tunnel lining layer includes the following process steps: S1. Weld a lining layer steel frame according to the tunnel arch surface, and set up several vibrator brackets in the steel frame along the length direction of the tunnel; S2. A steel formwork is covered on the outer periphery of the steel frame to form a cavity for pouring concrete inside, a vibrator connected with a non-rigid traction member extends from the steel formwork at the proximal end in the length direction into the frame and cooperates with at least one vibrator support at the distal end, the non-rigid traction member is in a horizontally flattened state in the length direction of the tunnel, and the non-rigid traction member is in a unidirectionally wound state when pulling the vibrator to reset; S3, pouring concrete into the cavity and turning on the vibrator, pulling the non-rigid traction member from outside the cavity to drag the vibrator from the far end to the near end in the length direction, and during the movement, the vibrator bracket guides the vibrator to move in a straight line.

[0007] In the method for vibrating the tunnel lining in the length direction, the vibrating rod bracket is connected to the steel frame at a spacing less than the length of the vibrating rod to form a vibrating rod guide track along the length direction of the tunnel.

[0008] In the method for vibrating the tunnel lining in the length direction, the non-rigid traction member is driven by the tension along the length direction of the tunnel.

[0009] In the method for vibrating the tunnel lining in the length direction, the traction force of the non-rigid traction member on the vibrating rod acts at the center of the circle and operates along the axis of the vibrating rod.

[0010] In the method for vibrating in the length direction of the tunnel lining layer, the non-rigid traction member is formed by connecting a plurality of components end to end, and can be adaptively modified according to the construction length of the tunnel.

[0011] In the method of vibrating in the length direction of the tunnel lining layer, the non-rigid traction member exiting the pouring cavity portion is stored by folding or winding.

[0012] The present invention also provides a device for vibrating the tunnel lining in the length direction, including a sprocket, a chain and a vibrating rod, wherein at least a portion of the sprocket arranged on the frame is engaged with the chain, one end of the chain is coiled in a storage wheel arranged above the sprocket, and the other end of the chain is fixedly connected to the vibrating rod.

[0016] The advantages of the present invention are: The links of the chain used to push and pull the vibrator are connected by hinges. The vibration transmitted back by the vibrator during operation cannot be completely transmitted in the hinges. Therefore, the sprocket on the outside can efficiently drive the chain without being affected by the vibration, so that the vibrator moves in the concrete at a set rate. At the same time, there is a vibrator bracket in the pouring cavity to guide the movement trajectory of the vibrator to ensure the horizontal and linear movement of the vibrator.

[0017] The chain that has been released from the concrete pouring area on the outside can also be wound around the storage wheel, which greatly reduces the space occupied by the outer end of the equipment compared to the rigid guide, and the storage and release is also more convenient and quick.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the invention and combined with the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Example 1

[0031] The method of vibrating in the length direction of the tunnel lining layer includes the following process steps: S1. Weld a lining layer steel frame according to the tunnel arch surface, and set up several vibrator brackets in the steel frame along the length direction of the tunnel; S2. A steel formwork is covered on the outer periphery of the steel frame to form a cavity for pouring concrete inside, a vibrator connected with a non-rigid traction member extends from the steel formwork at the proximal end in the length direction into the frame and cooperates with at least one vibrator support at the distal end, the non-rigid traction member is in a horizontally flattened state in the length direction of the tunnel, and the non-rigid traction member is in a unidirectionally wound state when pulling the vibrator to reset; S3, pouring concrete into the cavity and turning on the vibrator, pulling the non-rigid traction member from outside the cavity to drag the vibrator from the far end to the near end in the length direction, and during the movement, the vibrator bracket guides the vibrator to move in a straight line.

[0032] In this embodiment, the vibrator support is connected to the steel frame at a spacing smaller than the length of the vibrator, forming a vibrator guide track along the length direction of the tunnel.

[0033] The non-rigid traction member is a chain, which has a bending restriction structure on one side. The bending restriction structure is arranged downward so that the bottom of the chain can be kept horizontal and flush, so that the vibrating rod rigidly connected to the far end of the chain can be kept suspended.

[0034] Although there is a guide for the vibrator support, it is not a full-path track, so a single-sided curved chain is needed to support the vibrator to keep it suspended horizontally. It can also be arranged in S2 to make it easier to pass through each support when the vibrator is extended into the starting position.

[0035] In this embodiment, the traction force of the chain acts on the center of the vibrating rod and operates along the axial center line direction of the vibrating rod.

[0036] Pulling the vibrator in a straight line from the center of the circle can maintain the original direction of movement to the greatest extent, so as to meet the standards of vibration operation.

[0037] In this embodiment, at least the lower portion of the sprocket is in meshing engagement with the chain for power transmission.

[0038] The chain is not provided with a baffle on one side to limit unilateral bending so that it can mesh with the sprocket. In order to keep the chain at the far end straight, the chain can only mesh with the lower side of the sprocket to transmit power at the same time.

[0039] In this embodiment, the chain passing through the sprocket outside the cavity is wound in the receiving wheel above the sprocket.

[0040] Placing the storage wheel at the top can increase the tightness of the engagement between the chain and the lower side of the sprocket, preventing the power transmission point from loosening.

[0041] Example 2

[0042] The device for vibrating the tunnel lining in the length direction is operated according to the method for vibrating the tunnel lining in the length direction of the tunnel lining in Example 1.

[0043] The vibrating device includes a frame 4 and a vibrating rod 3 which moves horizontally based on the frame 4. A sprocket 1 is rotatably arranged on the frame 4. A chain 2 is meshed on the lower side of the sprocket 1. The vibrating rod 3 is rigidly connected to the end link of the chain 2 and is connected to the cable 8 through a connecting sheath 7. The other end of the chain 2 is wound in a storage wheel 5 arranged on the frame 4. A bending limiting structure is arranged on the side of the chain 2 facing away from the sprocket 1. When the chain 2 tilts toward the bending limiting structure side, each link remains arranged in a straight line.

[0044] That is, each link of the chain used to push and pull the vibrating rod is connected in a hinged manner, so that the vibration transmitted back by the vibrating rod during operation cannot be completely transmitted in the hinge, and at the same time, the vibrating rod can be sufficiently supported by the bending limiting structure on the lower side under the action of gravity. Therefore, the sprocket on the outside can efficiently drive the chain without being affected by the vibration, so that the vibrating rod moves in the concrete at a set rate.

[0045] The chain that has been released from the concrete pouring area on the outside can also be wound around the storage wheel, which greatly reduces the space occupied by the outer end of the equipment compared to the rigid guide, and the storage and release is also more convenient and quick.

[0046] In this embodiment, a baffle 6 is provided on the frame 4 to engage with the chain and the sprocket 1 , and the bending limiting structure slides against the baffle 6 .

[0047] When there is no receiving wheel 5 to provide tension, the chain at the lower side of the sprocket cannot mesh with the sprocket under the action of gravity. Therefore, a baffle is set at the lower side of the sprocket to support the chain and allow the chain to fit exactly with the sprocket, creating conditions for power transmission between the chain and sprocket through the baffle.

[0048] In this embodiment, the baffle 6 includes two continuous curved portions and a straight portion. The curved portion is concentrically arranged at the edge of the lower side of the sprocket 1 that engages with the chain 2 , and the straight portion extends toward the vibrator 3 in a horizontal state.

[0049] Alternatively, the baffle plate 6 is horizontally arranged just below the sprocket wheel 1 , and one side of the baffle plate 6 extends toward the vibrating rod 3 .

[0050] Regardless of how the baffle is set, it is necessary to provide sufficient force at the meshing point of the chain and the sprocket to keep the two meshing together, ensure the continuity of power transmission, and have an outwardly extending plane to serve as a horizontal outward support point for the chain.

[0051] The difference is that the storage wheel of the baffle with a curved surface needs to be installed above the sprocket, while the storage wheel of the baffle with only a straight surface can be installed at the same height as the sprocket, depending on the space occupied by the equipment.

[0052] In this embodiment, the bending limiting structure is a sheet-shaped baffle 21 provided on each link on the same side of the chain 2, and when the baffles 21 of adjacent links abut against each other, the two links remain arranged in a straight line.

[0053] The unilateral bending function of the chain is mainly achieved by the baffles set on each chain link. The baffles are only set on one side of the chain link. When the chain tilts to this side, the baffles abut against each other to prevent the chain from tilting to this side, so that the chain can maintain a straight state to support the vibrating rod.

[0054] In this embodiment, a placement channel is formed between each baffle 21 and the chain, and a cable 8 connected to the vibrating rod 3 is arranged in the placement channel.

[0055] The gaps between the baffles 21 and the chain shafts in each chain link are connected to each other to form a placement channel, and passing the cables through the channel can further protect the safety of the cables when they are bent.

[0056] In this embodiment, the connecting sheath 7 is arranged at the connection between the cable 8 and the vibrating rod 3 , and the cable 8 is provided with a waterproof joint 71 which abuts against the wire hole at the end of the vibrating rod 3 , and the connecting sheath 7 covers the waterproof joint 71 therein.

[0057] The connecting sheath 7 is used to relieve the pulling force between the cable and the vibrating rod, and a waterproof joint is also arranged therein to abut against the wire inlet of the vibrating rod to prevent water from seeping into the concrete and entering the interior of the vibrating rod.

[0058] In this embodiment, the cable 8 includes a conductor 81 and a steel wire rope 82 . The conductor 81 passes through the waterproof connector 71 and is connected to the vibrator 3 . The steel wire rope 82 is clamped by the wire clamp 72 in the connecting sheath 7 and fixed to the surface of the vibrator 3 .

[0059] The steel wire rope 82 further strengthens the connection between the cable and the vibrator and prevents the wire from being pulled. The outer side of the wire 81 is coated with a reinforcement structure, and a cable assembly is formed between the reinforcement structure and the wire 81. The cable assembly can make the vibrator 1 conductive and can pull the vibrator 1 up and down.

[0060] The conductor 81 can supply power to the vibrator stably and continuously. Under the effect of the reinforcement structure, the reinforcement rope cable has a relatively high strength, so the vibrator can be pulled directly through the reinforcement rope cable.

[0061] The reinforcement structure includes a steel wire rope 82 and an outer sheath 83 . The number of the above-mentioned conductors 81 is several, and the several conductors 81 are evenly distributed circumferentially on the outside of the steel wire rope 82 and a reinforced conductive unit is formed between the several conductors 81 and the steel wire rope 82 . The reinforced conductor unit is located in the outer sheath 83 .

[0062] There is a filling gap between the outer protective layer 83 and the reinforced conductive unit, and there is a filler 5 in the filling gap.

[0063] The filler 5 is silica gel. According to actual conditions, it is also feasible that the filler 5 is polypropylene wax.

[0064] The filler 5 is stably filled in the filling gap, which can ensure the connection tightness of the wire 81 and prevent the wire 81 from being subjected to stress alone during use.

[0065] The outer diameter of the steel wire rope 82 is 1 / 4 of the outer diameter of the conductor. According to actual conditions, it is also feasible that the outer diameter of the steel wire rope 82 is 1 / 3 of the outer diameter of the conductor.

[0066] The steel wire rope 82 itself has relatively high strength, so the outer diameter of the steel wire rope 82 is smaller than the outer diameter of the conductor 81 and can also ensure that the entire cable has sufficient strength.

[0067] The conductor 81 is spirally wound around the wire rope 82 .

[0068] Such a structure can improve the connection stability between the conductor 81 and the wire rope 82.

[0069] The steel wire rope 82 is a steel wire rope. According to actual conditions, it is also feasible that the steel wire rope 82 is a braided rope.

[0070] The outer sheath 83 is made of plastic material.

[0071] Since the conductor and the reinforcement layer of the vibrator of the reinforced rope cable are both covered in the sheath, the entire reinforced rope cable has relatively high strength. The vibrator can be directly pulled through the reinforced rope cable, and its stability and applicability are relatively high.

[0072] In this embodiment, the receiving wheel 5 is arranged at a level not lower than the sprocket 1 and rotates synchronously with the sprocket 1 , and the chain 2 is bent toward the side opposite to the bending limiting structure and is wound around the receiving wheel 5 .

[0073] The storage wheel 5 not only solves the problem of orderly storage of the long chain after being pulled out of the concrete, avoiding the situation where there is not enough space for the rigid guide, but also applies a certain tension to the chain after the chain is wound, so that the chain can engage with the sprocket more stably.

[0074] Preferably, the arc surface of the storage wheel 5 is provided with teeth that can mesh with the chain 2 .

[0075] Further providing teeth on the receiving wheel can increase the tension of the chain at the initial stage of winding, and can allow the chain to be wound on the receiving wheel in a more orderly manner.

[0076] Example 3

[0077] A double-row bearing is used in the vibrating rod of Example 2, including an outer ring 100 and an inner ring 110, both of which are cylindrical parts and are coaxially arranged. The outer ring 100 and the inner ring 110 are spaced apart and an installation cavity 120 is provided therebetween. The annular space of the installation cavity 120 is convenient for component installation and oil lubrication.

[0078] Specifically, a spherical roller annular groove 200 is annularly arranged in the mounting cavity 120. Specifically, arc-shaped notches 230 that are inwardly recessed and correspond to each other are provided on the inner wall of the outer ring 100 and the outer wall of the inner ring 110, and the arc-shaped notches 230 are communicated with the mounting cavity 120 to form the spherical roller annular groove 200. A plurality of spherical rollers 210 are provided in the spherical roller annular groove 200, and the number of spherical rollers 210 is determined according to the actual size. It can be imagined that the recessed depth of the arc-shaped notch 230 is less than the radius of the spherical roller 210, and the spherical roller 210 is partially located in the space of the mounting cavity 120, and the outer walls on both sides of the spherical roller 210 are matched and embedded in the arc-shaped notch 230. A spherical roller retainer 220 is also provided in the spherical roller annular groove 200. The spherical roller retainer 220 is provided with space for the spherical rollers 210 to be embedded one by one, so that the overall spherical rollers 210 are kept in a circumferential distribution in the spherical roller annular groove 200. The spherical rollers 210 are used to achieve axial limitation of the entire bearing, prevent relative displacement between the inner ring 110 and the outer ring 100, and have corresponding pressure-bearing performance in the axial and radial directions.

[0079] A cylindrical roller annular groove 300 is also annularly arranged in the installation cavity 120, and the cylindrical roller annular groove 300 is spaced apart from the spherical roller annular groove 200. Specifically, the inner wall of the end of the outer ring 100 away from the arc-shaped notch 230 and the outer wall of the inner ring 110 are provided with corresponding reaming notches 330, and the reaming notches 330 are communicated with the installation cavity 120 to form the cylindrical roller annular groove 300. A plurality of cylindrical rollers 310 are arranged in the cylindrical roller annular groove 300, and the number of cylindrical rollers 310 is determined according to the actual size. The recessed depth of the reaming notch 330 is smaller than the radius of the cylindrical roller 310, and the cylindrical roller 310 is partially located in the space of the installation cavity 120, and the outer walls on both sides of the cylindrical roller 310 fit in the inner wall of the reaming notch 330. A cylindrical roller retainer 320 is provided in the cylindrical roller annular groove 300, and the cylindrical roller 310 is kept circumferentially distributed in the cylindrical roller annular groove 300 by the cylindrical roller retainer 320. The cylindrical roller 310 can make the double-row bearing bear a greater radial force. In this embodiment, the expansion notch 330 is opened axially inward from the end of the installation cavity 120, which is convenient for machining the cylindrical roller annular groove 300 and installing the cylindrical roller 310.

[0080] Optimally, a step 340 is provided at one end of the expansion notch 330 close to the arc notch 230, and the cylindrical roller 310 abuts axially against the step 340, and the structure of the outer ring 100 and the inner ring 110 is used as the axial limit of the single end of the cylindrical roller 310, which facilitates the installation stability of the cylindrical roller 310 in the cylindrical roller annular groove 300. A clearance groove 350 is provided at one end of the expansion notch 330 close to the step 340, and the clearance groove 350 facilitates the inflow of lubricating oil, provides a sufficient lubrication surface on the side of the cylindrical roller 310 close to the step 340, and avoids wear of the corner end of the step 340.

[0081] In this embodiment, a clamping groove 360 ​​is provided at one end of the expansion hole notch 330 away from the step 340, and a clamping spring 370 is provided in the clamping groove 360 ​​to prevent the cylindrical roller 310 from being separated from the cylindrical roller annular groove 300. The clamping spring 370 is a C-shaped spring leaf, which is elastically embedded in the clamping groove 360 ​​to provide axial restriction on the other end of the cylindrical roller 310. Optimally, a retaining ring 380 is provided between the retaining ring 370 and the end of the cylindrical roller 310, and the retaining ring 380 increases the contact surface with the cylindrical roller 310, and the retaining ring 380 increases the rotation performance of the end of the cylindrical roller 310, thereby improving the rotation performance of the bearing.

[0082] The expansion notch 330 may also be disposed in the middle of the mounting cavity 120 .

[0083] The inner diameter of the spherical roller annular groove 200 and the inner diameter of the cylindrical roller annular groove 300 are both larger than the inner diameter of the mounting cavity 120. This structure prevents the spherical roller 210 and the cylindrical roller 310 from interfering with each other in their respective spherical roller annular grooves 200 and cylindrical roller annular grooves 300. More optimally, the inner diameter of the cylindrical roller annular groove 300 is larger than the inner diameter of the spherical roller annular groove 200, and the radial pressure bearing performance of the bearing is improved by the cylindrical roller 310. At the same time, the cylindrical roller 310 preferentially bears the radial force of the bearing, which plays a role in protecting the bearing. In addition, the double-row bearing formed with the spherical roller 210 supplements the axial positioning capability, and avoids the problem of misalignment between the outer ring 100 and the inner ring 110.

[0084] In this embodiment, mounting grooves 400 are provided at both ends of the mounting cavity 120. Dust covers 410 are provided in the mounting grooves 400 to seal both ends of the mounting cavity 120. The dust covers 410 prevent dust and impurities from entering the bearing and affecting the performance of the bearing.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
