Description

Technical Field

[0001] This invention relates to the field of tunnel wall reinforcement construction technology, specifically to a tunnel wall reinforcement layout device and method. Background Technology

[0002] After tunnel excavation, anchor spraying is required first, followed by the binding of tunnel reinforcement bars. The tunnel wall reinforcement bars consist of longitudinal bars extending along the tunnel's longitudinal direction and ring bars laid along the tunnel's cross-section. After the reinforcement bars are fully laid out, the secondary lining reinforced concrete is poured. Some tunnels have a single layer of ring bars and longitudinal bars, while others have a double layer of ring bars and longitudinal bars. This large-scale project severely restricts the construction progress of the tunnel secondary lining concrete. Currently, the tunnel reinforcement ring bars are manually transported or lifted by cantilever cranes, which still presents the following problems:

[0003] 1. Currently, for ring reinforcement binding operations, for ring reinforcement with a diameter of less than 20 mm, one person stands on each side platform of the trolley and two people stand on the top platform. The ring reinforcement is manually bent and shaped before being tied in place. For ring reinforcement with a diameter of more than 20 mm, the ring reinforcement is shaped in the steel bar processing plant outside the tunnel and then transported to the tunnel. It is then manually moved to place and tied.

[0004] 2. Due to the varying thickness of the secondary lining concrete within the same tunnel, the tying work platform cannot be of a fixed size. Therefore, the tying work platforms are all temporary, making the operation complex and unsafe, and failing to meet the safety requirements for high-altitude operations and operations near the edge of the borehole.

[0005] 3. The binding of longitudinal reinforcement bars relies entirely on manual handling, with low mechanization and very high physical demands on people, especially the binding of ring reinforcement bars, which is even more labor-intensive, resulting in low efficiency of reinforcement binding operations.

[0006] Therefore, it is necessary to study and design a tunnel wall reinforcement laying device to realize the automatic laying of tunnel wall reinforcement. Summary of the Invention

[0007] This invention provides a device and method for laying steel reinforcement in tunnel walls, which can automatically bend steel reinforcement into rings and automatically transport the rings, reducing manual labor and labor intensity, shortening the transport time of the rings, and thus improving the construction efficiency of the ring reinforcement laying operation.

[0008] This invention is achieved through the following technical solution:

[0009] In a first aspect, the present invention provides a tunnel wall reinforcement laying device, comprising: a trolley body; a ring reinforcement forming machine, wherein the ring reinforcement forming machine is disposed on one side of the trolley body facing the tunnel opening, the ring reinforcement forming mechanism including a straightening mechanism and a first forming mechanism, the straightening mechanism being capable of vertically straightening the reinforcement, and the first forming mechanism being capable of bending the straightened reinforcement into ring reinforcement; a ring reinforcement forming groove, wherein the ring reinforcement forming groove is disposed on the end of the trolley body facing the tunnel opening, the ring reinforcement forming groove being used to store the reinforcement output by the ring reinforcement forming machine; and a ring reinforcement demolding machine, the ring reinforcement demolding machine including a demolding frame, The system includes a demolding lifter and a longitudinal rib-picking mechanism. The longitudinal rib-picking mechanism is installed on the upper end of the demolding frame, and the demolding lifter is used to lift the demolding frame to eject the ring rib from the ring rib forming groove. A ring rib conveyor includes a conveyor frame, a feeding mechanism, a traveling mechanism, and a feeding lifter. The feeding lifter is installed on the traveling mechanism, and the conveyor frame is installed on the upper end of the feeding lifter and can receive the ring ribs taken out from the ring rib demolding machine. The traveling mechanism can drive the conveyor frame to move longitudinally. A longitudinal rib laying system is installed on the trolley body and can automatically lay the longitudinal ribs to the binding station.

[0010] The tunnel wall reinforcement laying device provided by this invention includes a ring reinforcement forming machine and a ring reinforcement forming trough at one end of the trolley body facing the tunnel entrance, a ring reinforcement demolding machine and an environmental conveyor at the middle of the top of the trolley body, and a longitudinal reinforcement laying system. The ring reinforcement forming machine includes a straightening mechanism capable of vertically straightening the reinforcement and a mechanism capable of bending the straightened reinforcement into ring reinforcement. The ring reinforcement forming trough is used to store the reinforcement output by the ring reinforcement forming machine. The ring reinforcement demolding machine includes a demolding frame, a demolding lifter, and a longitudinal reinforcement laying system. The longitudinal rib removal mechanism is installed on the upper end of the demolding frame. The demolding lifter is used to lift the demolding frame to push the rib out of the rib forming groove. The rib conveyor includes a conveyor frame, a feeding mechanism, a traveling mechanism, and a feeding lifter. The feeding lifter is installed on the traveling mechanism, and the conveyor frame is installed on the upper end of the feeding lifter. The conveyor can receive the ribs taken out from the rib demolding machine. The traveling mechanism can drive the conveyor frame to move longitudinally. The longitudinal rib laying system can automatically lay the longitudinal ribs to the binding station.

[0011] In operation, the reinforcing bars are first fed into the ring bar forming machine, where they are bent into rings and placed into the ring bar forming groove. Then, a demolding jack lifts the demolding frame, ejecting the ring bars from the forming groove. The ring bar transport machine is then moved to the demolding machine's position, and the demolding jack lifts are reset, allowing the ring bars to fall onto the transport frame. Finally, a traveling mechanism moves the ring bar transport machine to a set position, and a material lifting jack lifts the ring bars to the binding position. Simultaneously, a longitudinal reinforcement laying system automatically lays the longitudinal reinforcement to the binding position. Therefore, the tunnel wall reinforcing bar laying device provided by this invention can automatically bend reinforcing bars into rings, automatically transport the ring bars, and automatically lay the longitudinal reinforcement to the binding position. This reduces manual labor and labor intensity, shortens the reinforcing bar transport time, and thus improves the construction efficiency of tunnel wall reinforcing bar laying operations.

[0012] In an optional embodiment, the straightening mechanism is vertically provided with multiple straightening wheel pairs, each of the straightening wheel pairs being provided with a straightening drive wheel and a straightening driven wheel. The distance between the straightening driven wheel and the straightening drive wheel can be automatically adjusted so as to vertically straighten the reinforcing bars through the multiple straightening wheel pairs and to avoid the sleeve of the reinforcing bars by adjusting the distance between the straightening driven wheel and the straightening drive wheel.

[0013] In an optional embodiment, the first forming mechanism includes two vertically spaced forming support wheels, a first forming wheel, and a first forming linear actuator. The first forming linear actuator can push the first forming wheel between the two forming support wheels, so as to bend the straightened steel bar into a ring bar by pushing the first forming wheel with the first forming linear actuator.

[0014] In an optional embodiment, the rebar forming machine further includes: a shaping mechanism comprising multiple shaping wheel pairs arranged longitudinally, each shaping wheel pair being provided with a shaping drive wheel and a shaping driven wheel, the distance between the shaping driven wheel and the shaping drive wheel being automatically adjustable; and a second forming mechanism comprising a second forming wheel and a second forming linear actuator, the second forming linear actuator being capable of vertically pushing the second forming wheel; wherein, the shaping mechanism can longitudinally straighten the rebar and longitudinally transport the longitudinally straightened rebar, and the second forming wheel can upwardly bend the rebar output by the shaping mechanism.

[0015] The forming drive wheel of the forming wheel set drives the reinforcing bar to move along the arrangement direction of multiple forming wheel sets, while straightening the reinforcing bar. When the sleeve at the joint of the reinforcing bar enters the corresponding forming wheel set, the passage gap of the corresponding forming wheel set is widened to avoid the sleeve. At the same time, the forming wheel set feeds the straightened reinforcing bar into the second forming mechanism. The second forming linear drive of the second forming mechanism pushes the second forming wheel upward, bending the straightened reinforcing bar towards the top of the tunnel. This automatically feeds the reinforcing bar into the straightening mechanism, where it is straightened again. This straightens the reinforcing bar from a bent state, avoiding the problem of reinforcing bar twisting when it enters the first forming mechanism from a bent state. This process bends the reinforcing bar from a horizontal conveying state into a ring bar extending along the tunnel cross section, facilitating the automatic feeding and automatic bending forming of the ring bar.

[0016] In an optional embodiment, the longitudinal rib-picking mechanism includes a longitudinal rib-moving drive assembly and a rib-clamping part. The longitudinal rib-moving drive assembly is used to drive the rib-clamping part to move longitudinally, and when the demolding elevator drives the demolding frame to move upward, the rib-clamping part can clamp the middle part of the ring rib, so that the longitudinal rib-picking mechanism drives the rib-clamping part to move longitudinally, so as to perform multiple demoldings.

[0017] In an optional embodiment, the feeding mechanism further includes a material stop driving assembly and multiple material stopes. The material stop driving assembly includes a material stop chain and a material stop sprocket. The multiple material stopes are mounted on the material stop chain, and the material stop sprocket is used to drive the material stop chain to move cyclically. When the traveling mechanism drives the transport frame to move, the material stop can block the ring ribs on the transport frame to ensure that the conveying device can store multiple ring ribs and that the material stop can move longitudinally in a cyclic manner without resetting, thereby further improving the demolding efficiency of the ring ribs.

[0018] In an optional embodiment, the walking mechanism includes a walking frame, a walking guide rail, and a walking drive assembly. The walking drive assembly is mounted on the walking frame and can drive the walking frame to walk along the walking guide rail, so as to ensure that the walking mechanism can move longitudinally on its own.

[0019] In an optional embodiment, the longitudinal reinforcement placement system includes: a trolley body; a longitudinal reinforcement distribution mechanism, located on one side of the unloading channel of the trolley body, for storing longitudinal reinforcements unloaded from the steel reinforcement transport vehicle and capable of outputting single longitudinal reinforcements; and a longitudinal reinforcement picking and delivering mechanism, including a picking and delivering longitudinal beam and a tilting drive assembly. The picking and delivering longitudinal beam is provided with multiple longitudinal reinforcement gripping components and multiple linear feed actuators spaced apart along its length. The length direction of each linear feed actuator is perpendicular to the picking and delivering longitudinal beam and is used to push the longitudinal reinforcement gripping components. The tilting drive... The moving component is driven to the picking and feeding longitudinal beam and is used to drive the picking and feeding longitudinal beam to rotate along its own length direction; the longitudinal rib laying mechanism is used to transfer the longitudinal ribs output by the longitudinal rib distribution mechanism to the clamping position of the longitudinal rib gripping component; the longitudinal rib conveying mechanism includes a laying ring rail and a circumferential drive component. The laying ring rail is set at one end of the trolley body. The circumferential drive component is driven to the laying ring rail and connected to the longitudinal rib picking and feeding mechanism. The circumferential drive component is used to drive the longitudinal rib picking and feeding mechanism to move along the laying ring rail.

[0020] In operation, the reinforcing bars are fed into the longitudinal bar distribution mechanism to output single longitudinal bars. The longitudinal bar distribution mechanism then transfers the output longitudinal bars to the clamping position of the longitudinal bar gripping component. The gripping component then picks up the longitudinal bars output by the longitudinal bar distribution mechanism. A flipping drive component rotates the pick-and-place longitudinal beam, causing the gripping component to rotate to the outside of the trolley. A circumferential drive component then moves the pick-and-place longitudinal beam circumferentially along the laying track, moving the longitudinal bar to the corresponding position. Finally, a linear actuator pushes out the gripping component, laying the longitudinal bar to the corresponding binding position. Multiple gripping components and linear actuators are spaced along the length of the pick-and-place longitudinal beam to ensure the stability of the longitudinal bars during gripping or transfer, thus enabling automatic laying of the longitudinal bars. This reduces manual labor and labor intensity, shortens the laying time, and improves the construction efficiency of longitudinal bar laying operations.

[0021] In an optional embodiment, the longitudinal rib gripping assembly includes a longitudinal rib gripping disc, which is connected to the fabric linear actuator. The longitudinal rib gripping disc is provided with multiple longitudinal rib grippers and multiple gripping actuators. Each gripping actuator is drivenly connected to the corresponding longitudinal rib gripper and is used to drive the corresponding longitudinal rib gripper to grip the longitudinal rib, so as to transfer multiple longitudinal ribs at one time and improve the efficiency of longitudinal rib laying.

[0022] Secondly, the present invention provides a method for arranging reinforcement bars in tunnel walls, based on the aforementioned tunnel wall reinforcement bar arrangement device, comprising the following steps:

[0023] S10. Feed the reinforcing bar into the ring bar forming machine to bend the reinforcing bar into a ring bar and feed it into the ring bar forming groove;

[0024] S20. The demolding frame is lifted by the demolding elevator to push the ring rib out from the ring rib forming groove;

[0025] S30. Move the ring reinforcement conveyor to the work station of the demolding machine and reset the demolding lifting device so that the ring reinforcement falls onto the conveyor frame;

[0026] S40. The walking mechanism drives the ring reinforcement conveyor to a set position, and the ring reinforcement is lifted to the binding station by the material feeding and lifting device.

[0027] S50. After the ring reinforcement is laid out, the longitudinal reinforcement distribution mechanism outputs a single longitudinal reinforcement.

[0028] S60. The longitudinal ribs output by the longitudinal rib distribution mechanism are transferred to the clamping station of the longitudinal rib gripping component through the longitudinal rib feeding mechanism.

[0029] S70. The longitudinal ribs output by the longitudinal rib feeding mechanism are gripped by the longitudinal rib gripping component;

[0030] S80, The flipping drive assembly drives the pick-and-place longitudinal beam to flip, causing the longitudinal rib gripping assembly to flip to the outside of the trolley;

[0031] S90. The circumferential drive assembly drives the longitudinal beam to move circumferentially along the laying ring track, moving the longitudinal reinforcement to the corresponding position. Then, the linear material feeding driver pushes out the longitudinal reinforcement gripping assembly, laying the longitudinal reinforcement to the corresponding binding station.

[0032] The tunnel wall reinforcement laying method provided by the present invention is based on the aforementioned tunnel wall reinforcement laying device. First, the reinforcement is fed into the ring reinforcement forming machine to bend the reinforcement into rings and feed them into the ring reinforcement forming groove. Then, the demolding frame is lifted by the demolding lifter to push the ring reinforcement out of the ring reinforcement forming groove. Next, the ring reinforcement transport machine is moved to the demolding machine station and the demolding lifter is reset so that the ring reinforcement falls onto the transport frame. Finally, the traveling mechanism drives the ring reinforcement transport machine to the set position and lifts the ring reinforcement to the binding station by the material feeding lifter. This method can automatically bend the reinforcement into rings and automatically complete the conveying of the ring reinforcement.

[0033] Simultaneously, a single longitudinal rib is output through the longitudinal rib distribution mechanism, and then the longitudinal rib distribution mechanism transfers the longitudinal rib output by the longitudinal rib distribution mechanism to the clamping station of the longitudinal rib gripping component. The longitudinal rib gripping component then grips the longitudinal rib output by the longitudinal rib distribution mechanism. The flipping drive component drives the pick-and-place longitudinal beam to flip, causing the longitudinal rib gripping component to flip to the outside of the trolley. Then, the circumferential drive component drives the pick-and-place longitudinal beam to move circumferentially along the laying ring track, moving the longitudinal rib to the corresponding position. Finally, the laying linear driver pushes out the longitudinal rib gripping component, laying the longitudinal rib to the corresponding binding station, thus realizing the automatic laying of longitudinal ribs.

[0034] Therefore, the tunnel wall reinforcement layout method provided by the present invention can reduce manual labor and labor intensity, thereby shortening the conveying time of the ring reinforcement and improving the construction efficiency of the ring reinforcement layout operation.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] 1. The tunnel wall reinforcement laying device provided by the present invention includes a ring reinforcement forming machine and a ring environmental forming trough at one end of the trolley body facing the tunnel entrance, and a ring reinforcement demolding machine and an environmental conveyor at the middle of the top of the trolley body. The ring reinforcement forming machine includes a straightening mechanism capable of vertically straightening the reinforcement and a mechanism capable of bending the straightened reinforcement into ring reinforcement. The ring reinforcement forming trough is used to store the reinforcement output by the ring reinforcement forming machine. The ring reinforcement demolding machine includes a demolding frame, a demolding lifter, and a longitudinal rebar picking mechanism. The longitudinal rebar picking mechanism is installed on the upper end of the demolding frame. The demolding lifter is used to lift the demolding frame to push the ring reinforcement out of the ring reinforcement forming trough. The ring reinforcement conveyor includes a conveyor frame, a feeding mechanism, a traveling mechanism, and a feeding lifter. The feeding lifter is installed on the traveling mechanism, and the conveyor frame is installed on the upper end of the feeding lifter. Furthermore, the transport system can receive the ring bars taken out from the ring bar demolding machine. The traveling mechanism can drive the transport frame to move longitudinally, thereby bending the steel bars into ring bars by the ring bar forming machine and feeding them into the ring bar forming groove. Then, the demolding lifting device lifts the demolding frame, pushing the ring bars out of the ring bar forming groove. The ring bar transport machine is then moved to the demolding machine's work position, and the demolding lifting device is reset, causing the ring bars to fall onto the transport frame. Finally, the traveling mechanism drives the ring bar transport machine to the set position, and the feeding lifting device lifts the ring bars to the binding work position. This system can automatically bend the steel bars into ring bars and automatically complete the transport of the ring bars. The longitudinal bar laying system can automatically lay the longitudinal bars to the binding work position, which can reduce manual labor and labor intensity, shorten the transport time of the ring bars, and thus improve the construction efficiency of the ring bar laying operation.

[0037] 2. The tunnel wall reinforcement laying method provided by the present invention, based on the aforementioned tunnel wall reinforcement laying device, firstly feeds the reinforcement into the ring reinforcement forming machine to bend the reinforcement into rings and feeds them into the ring reinforcement forming groove. Then, the demolding frame is lifted by the demolding lifter to push the ring reinforcement out of the ring reinforcement forming groove. Next, the ring reinforcement transport machine is moved to the demolding machine's station and the demolding lifter is reset, so that the ring reinforcement falls onto the transport frame. Finally, the traveling mechanism drives the ring reinforcement transport machine to a set position, and the ring reinforcement is lifted to the binding station by the feeding lifter. This method can automatically bend the reinforcement into rings and automatically complete the conveying of the ring reinforcement. At the same time, a single longitudinal reinforcement is output through the longitudinal reinforcement distribution mechanism. The longitudinal reinforcement output from the longitudinal reinforcement distribution mechanism is then transferred to the clamping station of the longitudinal reinforcement gripping component via the longitudinal reinforcement placing mechanism. The longitudinal reinforcement gripping component then clamps the longitudinal reinforcement output from the longitudinal reinforcement placing mechanism. The flipping drive component drives the pick-and-place longitudinal beam to flip, causing the longitudinal reinforcement gripping component to flip to the outside of the trolley. Then, the circumferential drive component drives the pick-and-place longitudinal beam to move circumferentially along the laying ring track, moving the longitudinal reinforcement to the corresponding position. Finally, the linear feeder pushes out the longitudinal reinforcement gripping component, laying the longitudinal reinforcement to the corresponding binding station. This enables automatic laying of longitudinal reinforcement, thereby reducing manual labor and labor intensity, shortening the rebar conveying operation time, and improving the construction efficiency of rebar laying operations.

[0065] Example 1

[0066] Combination Figure 1 and Figure 2 This embodiment provides a tunnel wall reinforcement laying device, including: a trolley body 100; a ring reinforcement forming machine 200, which is located on one side of the trolley body 100 facing the tunnel opening, the ring reinforcement forming machine 200 including a straightening mechanism 210 and a first forming mechanism 220, the straightening mechanism 210 being able to vertically straighten the reinforcement, and the first forming mechanism 220 being able to bend the straightened reinforcement into ring reinforcement; a ring reinforcement forming groove 300, which is located on the one side of the trolley body 100 facing the tunnel opening, the ring reinforcement forming groove 300 being used to store the reinforcement output by the ring reinforcement forming machine 200; and a ring reinforcement demolding machine 400, which is used to demold the ring reinforcement. The molding machine 400 includes a demolding frame 410, a demolding lifter 420, and a longitudinal rib-picking mechanism 430. The longitudinal rib-picking mechanism 430 is installed on the upper end of the demolding frame 410. The demolding lifter 420 is used to lift the demolding frame 410 to push the ring rib out from the ring rib forming groove 300. The ring rib conveyor 500 includes a conveyor frame 510, a feeding mechanism 520, a traveling mechanism 530, and a feeding lifter 540. The feeding lifter 540 is installed on the traveling mechanism 530. The conveyor frame 510 is installed on the upper end of the feeding lifter 540 and can receive the ring ribs taken out from the ring rib demolding machine 400. The traveling mechanism 530 can drive the conveyor frame 510 to move longitudinally.

[0067] Combination Figure 3Specifically, the ring reinforcement forming machine 200 includes: a straightening mechanism 210, which has multiple straightening wheel pairs 211 arranged vertically, each of the straightening wheel pairs 211 having a straightening drive wheel 211a and a straightening driven wheel 211b, the distance between the straightening driven wheel 211b and the straightening drive wheel 211a being automatically adjustable; and a first forming mechanism 220, which includes two vertically spaced forming support wheels 221, a first forming wheel 222, and a first forming linear actuator 223, the first forming linear actuator 223 being able to push the first forming wheel 222 between the two forming support wheels 221; wherein, the straightening mechanism 210 is able to vertically straighten the reinforcing bars and feed the vertically straightened reinforcing bars into the first forming mechanism 220 to bend the reinforcing bars into ring reinforcements.

[0068] It also includes a molding mounting frame 230, on which the straightening mechanism 210 and the first molding mechanism 220 are both mounted, so as to facilitate the installation of the molding device in the tunnel or on the trolley.

[0069] Specifically, the correction mechanism 210 further includes: a first mounting base 213, which is slidably mounted on the molding mounting frame 230, and the correction driven wheel 211b is mounted on the first mounting base 213; and a correction avoidance linear actuator 214, which is mounted on the molding mounting frame 230, and the first mounting base 213 is connected to the correction avoidance linear actuator 214 in a transmission connection, so that the correction avoidance linear actuator 214 drives the corresponding correction driven wheel 211b to move away from or towards the corresponding correction drive wheel 211a, thereby adjusting the clearance of the corresponding correction wheelset 211.

[0070] Typically, the reinforcing bar feed end of the straightening mechanism 210 is equipped with a detection mechanism to determine whether the sleeve on the reinforcing bar has entered the straightening mechanism 210. This mechanism can be a displacement sensor, photoelectric sensor, etc., and only needs to be able to detect changes in the diameter of the reinforcing bar. When the detection mechanism detects that the sleeve has entered the straightening mechanism 210, it sends a feedback signal to the controller / control system. The controller / control system then controls the straightening linear actuator to move the corresponding straightening driven wheel 211b away from the corresponding straightening drive wheel 211a, thereby widening the clearance between the corresponding straightening wheel pair 211 and achieving the effect of avoiding the reinforcing bar connecting sleeve.

[0071] The first molding mechanism 220 includes a molding frame 224, and the first molding linear driver 223 and the two molding support wheels 221 are all mounted on the molding frame 224. The first molding linear driver 223 is used to drive the first molding wheel 222 to move.

[0072] In this embodiment, the first forming linear actuator 223 moves the forming wheel according to the distance calculated by the forming formula, causing the straightened steel bar to bend to the required diameter. The calculation model of the forming formula in this embodiment is as follows:

[0073]

[0074] In the formula, L is the perpendicular distance from the center of the forming wheel to the line connecting the centers of the two forming support wheels 221;

[0075] In the formula, r is the radius of the forming support wheel 221;

[0076] In the formula, R is the radius of the required circumferential reinforcement;

[0077] In the formula, a is the center distance between the two molded support wheels 221;

[0078] In the formula, r1 is the radius of the first forming wheel 222.

[0079] Based on this, the rebar forming machine 200 further includes: a shaping mechanism 240, which includes multiple shaping wheel pairs 241 arranged longitudinally, each shaping wheel pair 241 being provided with a shaping drive wheel 241a and a shaping driven wheel 241b, the distance between the shaping driven wheel 241b and the shaping drive wheel 241a being automatically adjustable; and a second forming mechanism 250, which includes a second forming wheel 251 and a second forming linear actuator 252, the second forming linear actuator 252 being able to vertically push the second forming wheel 251; wherein, the shaping mechanism 240 can longitudinally straighten the rebar and longitudinally transport the longitudinally straightened rebar, and the second forming wheel 251 can upwardly bend the rebar output by the shaping mechanism 240.

[0080] It is understandable that the forming drive wheel 241a of the forming wheel pair 241 drives the reinforcing bar to move along the arrangement direction of multiple forming wheel pairs 241, while straightening the reinforcing bar. When the sleeve at the joint of the reinforcing bar enters the corresponding forming wheel pair, the passage gap of the corresponding forming wheel pair 241 is widened to avoid the sleeve. At the same time, the forming wheel pair 241 inputs the straightened reinforcing bar into the second forming mechanism 250. The second forming linear driver 252 of the second forming mechanism 250 pushes the second forming wheel 251 upward, bending the straightened reinforcing bar of the forming mechanism 240 towards the top of the tunnel, thereby automatically inputting the reinforcing bar into the straightening mechanism 210, where it is straightened again. This straightens the reinforcing bar from a bent state, avoiding the problem of reinforcing bar twisting when it enters the first forming mechanism 220 from a bent state. This also bends the reinforcing bar from a horizontal conveying state into a ring bar extending along the tunnel cross section, facilitating the automatic feeding and automatic bending forming of the ring bar.

[0081] Meanwhile, the ring reinforcement forming machine 200 also includes multiple guide wheels 260, which are disposed between the forming wheel pair 241 and the straightening wheel pair 211. These guide wheels 260 guide the reinforcing bars formed by the second forming mechanism 250 into the straightening mechanism 210, ensuring that the reinforcing bars formed by the second forming mechanism 250 can enter the straightening mechanism 210. In this embodiment, the quarter-circle radius of the tread surface of the multiple guide wheels 260 is consistent with the forming radius of the reinforcing bars in the first forming device, so that the reinforcing bars can smoothly enter the straightening mechanism 210 under the guidance of the guide wheels 260.

[0082] Similarly, the shaping mechanism 240 further includes: a second mounting base 242, which is slidably mounted on the forming mounting frame 230, and the shaping driven wheel 241b is mounted on the second mounting base 242; and a shaping avoidance linear actuator 243, which is mounted on the forming mounting frame 230, and the second mounting base 242 is connected to the shaping avoidance linear actuator 243 in a transmission connection, so that the shaping avoidance linear actuator 243 drives the corresponding shaping driven wheel 241b to move away from or towards the corresponding shaping drive wheel 241a, thereby adjusting the clearance of the corresponding shaping wheel pair 241.

[0083] Preferably, the straightening drive wheel 211a and the shaping drive wheel 241a are driven synchronously by the same forming drive mechanism 270 to avoid the use of two sets of power systems causing asynchronous rotation speeds, which would result in mechanical vibration during the ring reinforcement forming process.

[0084] Combination Figure 4 Specifically, the forming drive mechanism 270 includes: a drive motor 271; an output reducer 272, which is driven by the drive motor 271; a bevel gear steering box 273, which is driven by the output reducer 272; a first drive shaft 274, which is driven by one output end of the bevel gear steering box 273, and each of the straightening drive wheels 211a is driven by the first drive shaft 274; and a second drive shaft 275, which is driven by the other output end of the bevel gear steering box 273, and each of the shaping drive wheels 241a is driven by the second drive shaft 275, to ensure that the rotational speeds of the straightening drive wheel 211a and the shaping drive wheel 241a are consistent.

[0085] In this embodiment, the output reducer 272 is a KA reducer (helical-bevel gear reducer), the first drive shaft 274 and the second drive shaft 275 are both connected to the corresponding drive wheels via worm gear reducers, and the drive motor 271 is not a variable frequency motor; the straightening and avoidance linear actuator 214 and the shaping and avoidance linear actuator 243 are both hydraulic cylinders to ensure that the straightening driven wheel 211b and the shaping driven wheel 241b can provide sufficient clamping force. The first forming linear actuator 223 and the second forming linear actuator 252 both use a lead screw and slider mechanism to ensure forming accuracy.

[0086] Combination Figure 5 Specifically, a portal frame is constructed using columns, triangular braces, and crossbeams. This portal frame secures the ring reinforcement forming groove 300 to the ground beam, which in turn fixes the ring reinforcement forming groove 300 to the trolley body 100. In actual operation, the portal frame is connected to the trolley body 100 via longitudinal beams, ensuring a secure fixation. Corresponding horizontal braces, vertical braces, and triangular braces are fixed to the portal frame and connected to the ring reinforcement forming groove 300 via connecting plates. Furthermore, the radius of the ring reinforcement forming groove 300 is the same as the radius of the ring reinforcement formed by the ring reinforcement forming machine 200, and they are concentric, preventing the reinforcement from sagging due to gravity, maintaining a circular shape, and preventing lateral swaying during the forming process.

[0087] Combination Figure 6 In order to reduce the resistance of the ring forming machine 200 in sending the formed ring into the ring forming groove 300, in this embodiment, the ring forming groove 300 includes a forming groove body 310, and a plurality of storage guide rollers 311 are arranged circumferentially on the forming groove body 310, and the roller bodies of the storage guide rollers 311 are respectively arranged on the inner side of the groove wall of the forming groove body 310.

[0088] Combination Figure 7 Specifically, the ring rib demolding machine 400 includes: a demolding frame 410, which is installed below the center of the ring rib forming groove 300 in the working state; a demolding lifter 420, which is fixed below the demolding frame 410; and a longitudinal rib-picking mechanism 430, which is installed on the upper end of the demolding frame 410. The longitudinal rib-picking mechanism 430 includes a longitudinal drive assembly 432 and a rib-clamping part 431. The longitudinal drive assembly 432 is used to drive the rib-clamping part 431 to move longitudinally. When the demolding lifter 420 drives the demolding frame 410 to move upward, the rib-clamping part 431 can clamp the center of the ring rib.

[0089] Generally, the demolding lifter 420 is a multi-stage hydraulic cylinder to reduce the installation space required for the demolding lifter 420, while ensuring that the demolding lifter 420 has sufficient lifting torque and lifting stroke. Of course, other linear actuators can also be used as the demolding lifter 420, such as electric actuators, pneumatic cylinders, etc.

[0090] In this embodiment, the retaining part 431 is a U-shaped retaining block with the opening facing upwards, to ensure that the retaining part 431 can be quickly engaged outside the ring reinforcement. Of course, the retaining part 431 can also be a V-shaped retaining block, a C-shaped retaining block, etc., with the opening facing upwards.

[0091] Typically, multiple retaining ribs 431 are longitudinally spaced to ensure that the demolding device can store multiple ring ribs, thereby improving the demolding efficiency of the ring ribs.

[0092] In this embodiment, the longitudinal movement drive component 432 is a cyclic drive component, which enables the retaining rib portion 431 to move longitudinally in a cyclic manner without needing to be reset, thereby further improving the demolding efficiency of the ring rib.

[0093] Specifically, the longitudinal movement drive assembly 432 includes a drive chain 432a and a drive sprocket 432b. A plurality of the retaining ribs 431 are mounted on the drive chain 432a. The drive sprocket 432b is used to drive the drive chain 432a to move cyclically, so as to drive the retaining ribs 431 to move cyclically through the drive chain 432a.

[0094] Generally, the drive sprocket 432b is connected to the demolding motor 432c via a reducer.

[0095] Based on this, a telescopic cylinder 440 is provided on one side of the demolding lifter 420 in the lifting direction. The upper end of the telescopic cylinder 440 is connected to the demolding frame 410, and the telescopic cylinder 440 extends and retracts with the extension and retraction of the demolding lifter 420 to prevent the demolding frame 410 from deflecting longitudinally when the demolding lifter 420 lifts the demolding frame 410.

[0096] Preferably, two telescopic cylinders 440 are provided, and along the longitudinal direction of the demolding frame 410, the two telescopic cylinders 440 are spaced apart on both sides of the demolding lifter 420, which further improves the stability of the demolding frame 410 during operation.

[0097] It is understood that the ring rib demolding machine 400 also includes a connecting base 450, which is used to connect the trolley body 100 at the lower part of the ring rib forming groove 300. The demolding lifter 420 and the telescopic cylinder 440 are both installed on the connecting base 450 so as to connect the demolding device to the trolley body 100.

[0098] Combination Figure 8 Specifically, the system includes: a transport frame 510; a feeding mechanism 520, which is mounted on the upper end of the transport frame 510 and includes a feeding stop 521; a traveling mechanism 530, which can travel longitudinally on its own; and a feeding lifter 540, which is mounted on the traveling mechanism 530 and the transport frame 510 is mounted on the upper end of the feeding lifter 540. When the traveling mechanism 530 moves the transport frame 510, the feeding stop 521 can block the ring rib on the transport frame 510.

[0099] Similarly, the material handling lifting device 540 is a multi-stage hydraulic cylinder to reduce the installation space required for the material handling lifting device 540, while ensuring that the material handling lifting device 540 has sufficient lifting torque and lifting stroke. Of course, other linear actuators can also be used as the material handling lifting device 540, such as electric actuators, pneumatic cylinders, etc.

[0100] In this embodiment, the upper end of the feeding and lifting device 540 is provided with a reinforcing support 541. The reinforcing support 541 extends longitudinally and is fixedly connected to the lower end of the transport frame 510 to ensure the stability of the transport frame 510.

[0101] It is understood that multiple pick-up stops 521 are longitudinally spaced to ensure that the conveying device can store multiple ring ribs, thereby improving the conveying efficiency of the ring ribs. Furthermore, the ring ribs can be secured between two adjacent pick-up stops 521, thus preventing the ring ribs from swaying.

[0102] Based on this, the feeding mechanism 520 also includes a material stop driving component 522, which is used to drive the material stop 521 to move longitudinally in a cyclic manner, so that the material stop 521 can move longitudinally in a cyclic manner without resetting, thereby further improving the conveying efficiency of the ring rib.

[0103] Specifically, the material stop drive assembly 522 includes a material stop chain 522a and a material stop sprocket 522b. Multiple material pick-up stops 521 are mounted on the material stop chain 522a, and the material stop sprocket 522b drives the material stop chain 522a to move cyclically. It should be understood that the material stop motor 522c is connected to the material stop sprocket 522b via a reducer to drive the material stop sprocket 522b to rotate, thereby driving the material stop chain 522a to move cyclically.

[0104] Furthermore, the feeding mechanism 520 is provided with two transversely spaced parts to prevent the ring reinforcement from deflecting when the conveying device is conveying the ring reinforcement.

[0105] The material feeding lifter 540 is provided with retractable supports 542 at intervals on both sides of the lifting direction. The retractable supports 542 are installed on the traveling mechanism 530. The upper end of the retractable supports 542 is connected to the transport frame 510. The retractable supports 542 extend and retract with the extension and retraction of the material feeding lifter 540 to prevent the transport frame 510 from deflecting laterally.

[0106] Combination Figure 9 The walking mechanism 530 includes a walking frame 531, a walking guide rail 532, and a walking drive component 533. The walking drive component 533 is mounted on the walking frame 531 and can drive the walking frame 531 to walk along the walking guide rail 532, so that the walking mechanism 530 can walk longitudinally on its own.

[0107] The travel drive assembly 533 can be a tracked travel assembly, a wheeled travel assembly, etc. In this embodiment, a gear and rack mechanism is used as the travel drive assembly 533. That is, the travel drive assembly 533 includes a travel gear 533a and a travel rack 533b. The travel gear 533a meshes with the travel rack 533b, and the travel rack 533b is arranged parallel to the travel guide rail 532. Generally speaking, the travel gear 533a is driven by a travel motor 534, while the travel gear 533a and 533b and the travel guide rail 532 are fixed to the travel beam provided on the trolley body 100.

[0108] Preferably, the walking mechanism 530 further includes a pair of guide wheels 535, which are disposed on the walking frame 531 and are engaged on the upper and lower sides of the walking guide rail 532 to ensure the stability of the walking mechanism 530 and prevent the walking mechanism 530 from slipping off or getting stuck on the walking guide rail 532.

[0109] Combination Figure 1 , Figure 2 , Figure 12 and Figure 13The longitudinal reinforcement placement system includes: a longitudinal reinforcement distribution mechanism 610, located on one side of the unloading channel of the trolley body 100, for storing longitudinal reinforcements unloaded from the steel reinforcement transport vehicle and capable of outputting single longitudinal reinforcements; and a longitudinal reinforcement picking and delivering mechanism 630, including a picking and delivering longitudinal beam 631 and a tilting drive assembly 632. The picking and delivering longitudinal beam 631 is provided with multiple longitudinal reinforcement gripping assemblies 633 and multiple linear feed actuators 634 spaced apart along its length. The length direction of each linear feed actuator 634 is perpendicular to the picking and delivering longitudinal beam 631, and it is used to push the longitudinal reinforcement gripping assembly 633. The tilting drive assembly 632 is connected to the picking and delivering longitudinal beam 631. A transmission connection is provided to drive the longitudinal beam 631 to rotate along its own length; a longitudinal reinforcement feeding mechanism 620 is provided to transfer the longitudinal reinforcement output by the longitudinal reinforcement distribution mechanism 610 to the clamping position of the longitudinal reinforcement gripping component 633; ​​a longitudinal reinforcement conveying mechanism 640 includes a laying ring rail 641 and a circumferential drive component 642. The laying ring rail 641 is located at one end of the trolley body 100. The circumferential drive component 642 is transmissionally connected to the laying ring rail 641 and connected to the longitudinal reinforcement feeding mechanism 630. The circumferential drive component 642 is used to drive the longitudinal reinforcement feeding mechanism 630 to move along the laying ring rail 641.

[0110] Combination Figure 10 and Figure 11 The longitudinal reinforcement distribution mechanism 610 includes: a distribution ramp 611 extending along the length of the trolley body 100; multiple distribution discs 612 spaced apart along the length of the distribution ramp 611, with each disc located beside the bottom side of the top surface of the ramp 611, and multiple distribution grooves evenly distributed around the sidewall of each disc 612 for accommodating a single longitudinal reinforcement bar; and a distribution motor 613 connected to the distribution disc 612 for driving the disc 612 to rotate along its own axial direction. The distribution discs 612 can hold the longitudinal reinforcement bars on the distribution ramp 611, ensuring that the longitudinal reinforcement distribution mechanism 610 can store longitudinal reinforcement bars unloaded from the steel bar transport vehicle and output single longitudinal reinforcement bars.

[0111] Combination Figure 14 Specifically, the longitudinal rib gripping assembly 633 includes a longitudinal rib gripping disc 633a, which is connected to the fabric linear actuator 634. The longitudinal rib gripping disc 633a is provided with a plurality of longitudinal rib grippers 633b (usually 5) and a plurality of gripping actuators 633c. Each gripping actuator 633c is connected to the corresponding longitudinal rib gripper 633b and is used to drive the corresponding longitudinal rib gripper 633b to grip the longitudinal rib, so as to transfer multiple longitudinal ribs at one time and improve the efficiency of longitudinal rib laying.

[0112] It is understood that the longitudinal rib gripper 633b includes a fixed gripper and a movable gripper. The fixed gripper is fixedly mounted on the longitudinal rib gripping disk 633a, and one end of the movable gripper is hinged to the longitudinal rib gripping disk 633a. The gripping driver 633c is a linear driver, and one end of the gripping driver 633c is hinged to the longitudinal rib gripping disk 633a, and the other end is hinged to the movable gripper, so as to ensure that the longitudinal rib gripper 633b can quickly and stably grip the longitudinal rib.

[0113] Furthermore, the fabric linear actuator 634 is connected to the longitudinal rib gripping assembly 633 via a synchronous lifting rod 635. The synchronous lifting rod 635 is set parallel to the pick-and-place longitudinal beam 631 to ensure that the fabric linear actuator synchronously lifts the longitudinal rib gripping assembly 633, so that the longitudinal rib will not be pulled during the lifting process, thus ensuring operational safety and the quality of the longitudinal rib placement.

[0114] In addition, a fabric synchronous telescopic cylinder 636 is provided on the pick-up and delivery longitudinal beam 631. The two ends of the fabric synchronous telescopic cylinder 636 are respectively connected to the corresponding ends of the fabric linear driver 634, so as to bear the radial force of the fabric linear driver 634 during the rotation of the pick-up and delivery longitudinal beam 631 through the synchronous telescopic cylinder, and avoid damage to the fabric linear driver 634.

[0115] Generally, rectangular tubes are used as the pick-up and delivery longitudinal beam 631 to ensure sufficient rigidity while facilitating the installation of the fabric synchronous telescopic cylinder 636 on the pick-up and delivery longitudinal beam 631. Similarly, the fabric synchronous telescopic cylinder 636 is formed by using a large rectangular tube inside a smaller rectangular tube.

[0116] The flip drive assembly 632 includes a rotating platform 632a and a flip drive motor 632b. The rotating platform 632a is fixedly connected to the end of the pick-and-place longitudinal beam 631, and the flip drive motor 632b is driven by the rotating platform 632a. The flip drive motor 632b can drive the rotating platform 632a to rotate along its own axis to ensure that the flip drive assembly 632 can drive the pick-and-place longitudinal beam 631 to rotate.

[0117] Recombined Figure 2 Specifically, the longitudinal reinforcement feeding mechanism 620 includes: a material-picking hook 621 for picking up the longitudinal reinforcement output by the longitudinal reinforcement distribution mechanism 610; a vertical feeding driver 622 for driving the material-picking hook 621 to move vertically; and a horizontal feeding driver 622 for driving the vertical feeding driver 622 to move horizontally. It is understood that the material-picking hook 621 can quickly pick up and release the longitudinal reinforcement. In this embodiment, an electric actuator is used as the vertical feeding driver 622, and a screw-slider mechanism is used as the horizontal feeding driver 622.

[0118] Combination Figure 15 The circumferential drive assembly 642 includes a ring shifter 642a, which is slidably mounted on the outer side of the layout ring rail 641. The ring shifter 642a is driven to move along the layout ring rail 641 by a gear mechanism. The flip drive assembly 632 is mounted on the ring shifter 642a to ensure that the reversing drive assembly can move along the layout ring rail 641.

[0119] It should be understood that the ring shifter 642a is provided with a ring shift drive gear 642b, and the ring track 641 is provided with a ring gear 643 that meshes with the ring shift drive gear 642b.

[0120] In this embodiment, the ring shift frame 642a is further provided with a ring shift support roller 642c and a ring shift clamping roller pair 642d. The ring shift support roller 642c abuts against the outer side of the layout ring rail 641, and the ring shift clamping roller pair 642d is engaged on both sides of the inner side of the layout ring rail 641 to ensure the stability of the reversing drive assembly moving on the layout ring rail 641.

[0121] In addition, two longitudinally spaced ring rails 641 are provided, and the two ends of the pick-up and delivery longitudinal beam 631 are respectively connected to the corresponding circumferential drive assembly 642 to ensure the stability of the movement of the pick-up and delivery longitudinal beam 631.

[0122] It should be noted that, in this embodiment, the steel bar after the sleeve is connected is fed into the shaping mechanism 240. The shaping drive wheel 241a of the shaping wheel pair 241 drives the steel bar to move along the arrangement direction of multiple shaping wheel pairs 241, while straightening the steel bar. When the sleeve at the connection of the steel bar enters the corresponding shaping wheel pair, the passage gap of the corresponding shaping wheel pair 241 is widened to avoid the sleeve. The straightened steel bar is then fed into the second forming mechanism 250 by the shaping wheel pair 241. The second forming linear driver 252 of the second forming mechanism 250 pushes the second forming wheel 251 upward, bending the straightened steel bar of the shaping mechanism 240 towards the top of the tunnel. It is then guided by the guide wheel 260, thereby automatically feeding the steel bar into the straightening mechanism 210, where it is straightened again, thus straightening the steel bar from its bent state.

[0123] Then, the straightening drive wheel 211a of the straightening wheel pair 211 drives the reinforcing bar to move along the arrangement direction of the multiple straightening wheel pairs 211, while straightening the reinforcing bar. When the sleeve at the joint of the reinforcing bar enters the corresponding straightening wheel pair 211, the passage gap of the corresponding straightening wheel pair 211 is widened to avoid the sleeve. Finally, the straightened reinforcing bar is input into the first forming mechanism 220 by the straightening wheel pair 211. The first forming linear actuator 223 of the first forming mechanism 220 pushes the first forming wheel 222 into the gap between the two forming support wheels 221, bending and forming the straightened reinforcing bar of the straightening mechanism 210 to the other side of the tunnel. At the same time, the formed ring reinforcing bar segment is introduced into the ring reinforcing bar forming groove 300.

[0124] The demolding frame 410 is installed on the trolley body 100 below the middle of the ring rib forming groove 300. After the ring rib is formed in the hole, the demolding frame 410 is lifted by the demolding lifter 420, so that the rib clamping part 431 on the longitudinal rib picking mechanism 430 is clamped outside the middle of the ring rib. The demolding frame 410 is further lifted by the demolding lifter 420 to push the corresponding ring rib out from the ring rib forming groove 300. Then, the longitudinal rib picking mechanism 430 drives the rib clamping part 431 to move longitudinally to complete the demolding of the ring rib. Subsequently, the transport frame 510 is moved to the discharge station of the ring rib demolding machine 400 by the traveling mechanism 530 (the transport frame 510 is intermittently locked outside the ring rib demolding machine 400). Then, the demolding lifter 420 retracts or the transport frame 510 is lifted by the feeding lifter 540, so that the feeding mechanism 520 supports the ring rib on the ring rib demolding machine 400, so that the ring rib is located within two adjacent feeding stops 521, thereby setting the ring rib on the feeding mechanism 520.

[0125] Then, the walking mechanism 530 drives the material feeding mechanism 520 to move longitudinally. After reaching the set position, the material feeding jack 540 lifts the conveying frame, thereby automatically conveying the ring reinforcement to the binding station to realize the automatic layout of the ring reinforcement of the tunnel wall.

[0126] Then, a single longitudinal rib is output through the longitudinal rib distribution mechanism 610, and then the longitudinal rib distribution mechanism 620 transfers the longitudinal rib output by the longitudinal rib distribution mechanism 610 to the clamping station of the longitudinal rib gripping component 633, so that the longitudinal rib gripping component 633 can grip the corresponding longitudinal rib. Then, the reverse drive component drives the flip drive component 632 to flip the pick-up and delivery longitudinal beam 631, so that the longitudinal rib gripping component 633 flips to the outside of the trolley. Then, the circumferential drive component 642 drives the pick-up and delivery longitudinal beam 631 to move circumferentially along the laying ring track 641, thereby moving the longitudinal rib to the corresponding position. Finally, the laying linear actuator 634 pushes out the longitudinal rib gripping component 633, thereby laying the longitudinal rib to the corresponding binding station. Among them, there are multiple longitudinal rib gripping components 633 and laying linear actuators 634 arranged at intervals along the length direction of the pick-up and delivery longitudinal beam 631 (usually 5), which can ensure the stability of the longitudinal rib during the gripping or transfer process.

[0127] In summary, the tunnel wall reinforcement laying device provided in this embodiment can automatically bend the reinforcement into rings, automatically transport the rings, and automatically lay the longitudinal reinforcement. This can reduce manual labor and labor intensity, shorten the transportation time of the tunnel wall reinforcement, and thus improve the construction efficiency of the tunnel wall reinforcement laying operation.

[0128] Example 2

[0129] Combination Figure 1 This embodiment provides a method for laying reinforcement bars in tunnel walls, based on the tunnel wall reinforcement bar laying device described in Embodiment 1, including the following steps:

[0130] S10. The reinforcing bar is fed into the ring bar forming machine 200 to bend the reinforcing bar into a ring bar and feed it into the ring bar forming groove 300.

[0131] Specifically, the reinforcing bars connected to the sleeves are first fed into the shaping mechanism 240. The shaping drive wheel 241a of the shaping wheel pair 241 drives the reinforcing bars to move along the arrangement direction of multiple shaping wheel pairs 241, while straightening the reinforcing bars. When the sleeve at the connection of the reinforcing bars enters the corresponding shaping wheel pair, the passage gap of the corresponding shaping wheel pair 241 is widened to avoid the sleeve. The straightened reinforcing bars are then fed into the second forming mechanism 250 by the shaping wheel pair 241. The second forming linear actuator 252 of the second forming mechanism 250 pushes the second forming wheel 251 upward, bending the straightened reinforcing bars of the shaping mechanism 240 toward the top of the tunnel. Guided by the guide wheel 260, the reinforcing bars are automatically fed into the straightening mechanism 210, where they are straightened again, thus straightening the reinforcing bars from their bent state.

[0132] Then, the straightening drive wheel 211a of the straightening wheel pair 211 drives the reinforcing bar to move along the arrangement direction of the multiple straightening wheel pairs 211, while straightening the reinforcing bar. When the sleeve at the joint of the reinforcing bar enters the corresponding straightening wheel pair 211, the passage gap of the corresponding straightening wheel pair 211 is widened to avoid the sleeve. Finally, the straightened reinforcing bar is input into the first forming mechanism 220 by the straightening wheel pair 211. The first forming linear actuator 223 of the first forming mechanism 220 pushes the first forming wheel 222 into the gap between the two forming support wheels 221, bending and forming the straightened reinforcing bar of the straightening mechanism 210 to the other side of the tunnel. At the same time, the formed ring reinforcing bar segment is introduced into the ring reinforcing bar forming groove 300.

[0133] S20. The demolding frame 410 is lifted by the demolding lifter 420, and the ring rib is pushed out from the ring rib forming groove 300.

[0134] Specifically, after the ring reinforcement is formed in the hole, the demolding frame 410 is lifted by the demolding lifter 420, so that the rib clamping part 431 on the longitudinal rib picking mechanism 430 is clamped outside the middle of the ring reinforcement. The demolding lifter 420 continues to lift the demolding frame 410, pushing the corresponding ring reinforcement out of the ring reinforcement forming groove 300. Then, the longitudinal rib picking mechanism 430 drives the rib clamping part 431 to move longitudinally to complete the demolding of the ring reinforcement.

[0135] S30. Move the ring reinforcement conveyor 500 to the work station of the demolding machine and reset the demolding lifter 420 so that the ring reinforcement falls onto the conveyor frame 510.

[0136] Specifically, the transport frame 510 is moved to the discharge station of the ring rib demolding machine 400 by the walking mechanism 530 (the transport frame 510 is spaced outside the ring rib demolding machine 400). Then the demolding lifter 420 retracts or the transport frame 510 is lifted by the feeding lifter 540, so that the feeding mechanism 520 supports the ring rib on the ring rib demolding machine 400, so that the ring rib is located in two adjacent feeding stops 521, thereby setting the ring rib on the feeding mechanism 520.

[0137] S40. The walking mechanism 530 drives the ring reinforcement conveyor 500 to move to the set position, and the ring reinforcement is lifted to the binding station by the material feeding and lifting device 540.

[0138] Repeat the above steps (S10-S40) to complete the layout of the ring reinforcement in one compartment.

[0139] S50. After the ring reinforcement is laid out, the longitudinal reinforcement distribution mechanism 610 outputs a single longitudinal reinforcement.

[0140] Specifically, the trolley body 100 has a discharge channel in the middle for steel bar transport vehicles to enter, allowing them to drive directly into the trolley body 100. A discharge lifting mechanism 650 (such as an electric hoist) is installed on the discharge channel to lift the longitudinal bars from the steel bar transport vehicle onto the distribution ramp 611. Under gravity, the longitudinal bars slide down the top surface of the distribution ramp 611 to the distribution plate 612, where they are held in place. When distribution is needed, the distribution motor 613 drives all the distribution plates 612 to rotate synchronously. Some longitudinal bars slide down into the distribution groove of the distribution plate 612 under gravity, and are output as the distribution plate 612 rotates, thus outputting a single longitudinal bar.

[0141] S60. The longitudinal ribs output by the longitudinal rib distribution mechanism 610 are transferred to the clamping station of the longitudinal rib gripping component 633 by the longitudinal rib feeding mechanism 620.

[0142] Specifically, after the material distribution plate 612 outputs a single steel bar, the material picker hook 621 is moved to the path of the longitudinal bar movement on the material distribution plate 612 by the cooperation of the horizontal material distribution driver 622 and the vertical material distribution driver 622. Then, the vertical material distribution driver 622 moves upward to hook the single longitudinal bar. Finally, the longitudinal bar is transferred to the clamping position of the longitudinal bar gripping component 633 by the cooperation of the horizontal material distribution driver 622 and the vertical material distribution driver 622.

[0143] S70. The longitudinal ribs output by the longitudinal rib feeding mechanism 620 are clamped by the longitudinal rib gripping component 633; ​​that is, the movable claw is driven to move towards the fixed claw by the clamping driver 633c to clamp the longitudinal ribs.

[0144] S80, the flipping drive assembly 632 drives the pick-and-place longitudinal beam 631 to flip, so that the longitudinal rib grabbing assembly 633 flips to the outside of the trolley.

[0145] S90. The circumferential drive assembly 642 drives the pick-and-place longitudinal beam 631 to move circumferentially along the laying ring rail 641, moving the longitudinal reinforcement to the corresponding position; and the longitudinal reinforcement gripping assembly 633 is pushed out by the material laying linear driver 634 to lay the longitudinal reinforcement to the corresponding binding station. After the reinforcement binding is completed, the longitudinal reinforcement clamp 633b is released, and all components are reset to prepare for the next cycle of longitudinal reinforcement laying.

[0146] It is understood that multiple longitudinal bar clamps 633b are provided, which can clamp and transfer multiple longitudinal bars at one time. In this embodiment, five longitudinal bars can be laid out at one time.

[0147] In summary, the tunnel wall reinforcement laying method provided in this embodiment is based on the tunnel wall reinforcement laying device described in Embodiment 1. First, the reinforcement is fed into the ring reinforcement forming machine to bend the reinforcement into rings and feed them into the ring reinforcement forming groove. Then, the demolding frame is lifted by the demolding lifter to push the ring reinforcement out of the ring reinforcement forming groove. Next, the ring reinforcement transport machine is moved to the demolding machine station and the demolding lifter is reset so that the ring reinforcement falls onto the transport frame. Finally, the traveling mechanism drives the ring reinforcement transport machine to the set position and lifts the ring reinforcement to the binding station by the material feeding lifter. This method can automatically bend the reinforcement into rings and automatically complete the conveying of the ring reinforcement. Simultaneously, a single longitudinal rib is output through the longitudinal rib distribution mechanism 610, and then the longitudinal rib output by the longitudinal rib distribution mechanism 620 is transferred to the clamping station of the longitudinal rib gripping component 633. The longitudinal rib gripping component 633 then grips the longitudinal rib output by the longitudinal rib distribution mechanism 620. The flipping drive component 632 drives the pick-and-place longitudinal beam 631 to flip, so that the longitudinal rib gripping component 633 flips to the outside of the trolley. Then, the circumferential drive component 642 drives the pick-and-place longitudinal beam 631 to move circumferentially along the laying ring track 641, moving the longitudinal rib to the corresponding position. Finally, the laying linear driver 634 pushes out the longitudinal rib gripping component 633, laying the longitudinal rib to the corresponding binding station, thus realizing the automatic laying of longitudinal ribs.

[0148] Therefore, this embodiment can reduce manpower and labor intensity, thereby shortening the transportation time of tunnel wall reinforcement and improving the construction efficiency of tunnel wall reinforcement layout.
