Description

Technical Field

[0001] This utility model relates to the field of tunnel ring reinforcement processing technology, specifically to a tunnel wall ring reinforcement forming device. Background Technology

[0002] After tunnel excavation, anchor spraying is carried out first, followed by the binding of tunnel reinforcement bars. The tunnel wall reinforcement bars are divided into longitudinal bars extending along the tunnel's longitudinal direction and ring bars arranged along the tunnel's cross-section. After the reinforcement bars are fully laid out, the secondary lining reinforced concrete is poured. When binding the ring bars, the ends of the ring bars must first be threaded outside the tunnel, and then the bars are bent into the required arc shape using reinforcement forming machinery.

[0003] Existing rebar forming machinery primarily controls the travel distance of the rebar within the forming machine by calculating the output and operating time of the drive mechanism via a control box. However, because the power transmission from the drive mechanism to the drive wheels propelling the rebar involves multiple transmission systems such as worm gear reducers, each stage of transmission introduces a certain transmission error. This results in discrepancies between the output of the drive mechanism and the actual rotation of the drive wheels, leading to inaccurate control of the rebar travel distance.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the travel distance of the reinforcing bars in the forming machine is not accurately controlled in the prior art. The purpose is to provide a tunnel wall ring reinforcement forming device, which adopts corresponding technical means and has the beneficial effects of accurate control of the reinforcing bar travel distance and accurate sleeve detection, avoiding sleeve collision, improving the ring reinforcement forming accuracy, and ensuring forming quality.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a tunnel wall ring reinforcement forming device, which includes an integrated steel frame. The integrated steel frame is equipped with a first forming mechanism, a straightening mechanism, a matrix laser sensor, and an encoder. The matrix laser sensor is located on the reinforcement inlet side of the first forming mechanism.

[0008] The first forming mechanism includes a pair of driving wheels and driven wheels. The driving wheel is connected to the encoder, and the driven wheel is connected to a collision avoidance linear actuator. The correction mechanism includes a pair of driving wheels and driven wheels. The driven wheel is connected to a collision avoidance linear actuator.

[0009] The matrix laser sensor and the encoder are electrically connected to a control box, which is controlled by the first obstacle avoidance linear actuator and the second obstacle avoidance linear actuator.

[0010] Furthermore, in this utility model, the above also includes a second forming mechanism, which includes a wheel frame connected to the integral steel frame. The wheel frame is provided with a fixed wheel and a pusher, and the pusher is connected to a pusher wheel.

[0011] Furthermore, in this utility model, the four drive wheels are arranged in a 70° arc shape, and the four drive wheels are arranged longitudinally.

[0012] Furthermore, in this utility model, the above also includes a drive motor connected to the integrated steel frame, the drive motor being connected to a reducer, the reducer being driven by the second drive wheel and the first drive wheel.

[0013] Furthermore, in this utility model, the axle of the reducer is provided with a first gear, and the main shaft of the encoder is provided with a second gear, which meshes with the first gear.

[0014] Furthermore, in this invention, the transmission ratio between the second gear and the first gear is 1:1.

[0015] Furthermore, in this utility model, the aforementioned integrated steel frame is provided with a push plate, the driven wheel one and the driven wheel two are disposed on the push plate, and the push plate is connected to the avoidance linear actuator one and the avoidance linear actuator two.

[0016] Furthermore, in this utility model, the push plate is provided with guide plates on both layers, and a guide groove adapted to the push plate is provided between the two guide plates.

[0017] Furthermore, in this utility model, the aforementioned obstacle avoidance linear actuator one and obstacle avoidance linear actuator two are connected to a hydraulic station, and the hydraulic station is controlled and connected by the control box.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] 1. By combining a matrix laser sensor and an encoder, the travel distance of the reinforcing bar can be accurately measured, avoiding the problem of inaccurate distance control caused by transmission errors and improving the forming accuracy of the ring reinforcement.

[0020] 2.

Furthermore, the avoidance linear actuators one and two can automatically adjust the positions of driven wheels one and two according to the movement of the reinforcing bars, facilitating the passage of the sleeve. After the sleeve passes, driven wheels one and two re-clamp the reinforcing bars, ensuring both driving and straightening effects.

[0028] This embodiment provides a tunnel wall ring reinforcement forming device, such as... Figures 1-2 As shown, the specific structure is described below.

[0029] The tunnel wall ring reinforcement forming device in this embodiment mainly consists of an integrated steel frame 1, a first forming mechanism 2, a straightening mechanism 3, a matrix laser sensor 4, an encoder 5, a second forming mechanism 9, a drive motor 10, and a hydraulic station.

[0030] Among them, the integrated steel frame 1: combined with Figure 1 and Figure 2 As shown, the integrated steel frame 1 serves as the main support structure of the tunnel wall ring reinforcement forming device. It is a rectangular frame welded from Q345B steel, exhibiting excellent stability and rigidity. It provides the installation foundation for other components, ensuring that each component maintains relative positional stability during operation.

[0031] First forming mechanism 2: such as Figure 1 As shown, the first forming mechanism 2 includes four driving wheels 201 and two driven wheels 202. The four pairs of driving wheels 201 are arranged in a 70° arc, with the driving wheels 201 located on the right and the driven wheels 202 located on the left. The structure is compact, reducing space occupation.

[0032] Combination Figure 1 As shown, the driven wheel 202 is connected to a linear actuator 6 for avoiding obstacles. In this embodiment, the linear actuator 6 for avoiding obstacles is a hydraulic cylinder. The base of the hydraulic cylinder is connected to the integrated steel frame 1, and the piston rod of the hydraulic cylinder is connected to the push plate 8. The driven wheel 202 is mounted on the push plate 8.

[0033] Furthermore, in combination Figure 1As shown, the integrated steel frame 1 is also equipped with guide plates 801. A guide groove is located between the two guide plates 801, and the extension direction of the guide groove is parallel to the movement direction of the piston rod. A push plate 8 is installed within the guide groove. The cooperation between the guide groove and the push plate 8 ensures the stability of the push plate 8 during movement. When a reinforcing bar passes through, the linear actuator 6 adjusts the position of the driven wheel 202 according to the condition of the reinforcing bar, so that the driven wheel 202 cooperates with the drive wheel 201 to clamp the reinforcing bar. When a sleeve passes through, the linear actuator 6 moves the driven wheel 202 away from the drive wheel 201, facilitating the passage of the sleeve.

[0034] In this embodiment, as Figure 1 As shown, the straightening mechanism 3 includes multiple pairs (four pairs in this embodiment) of longitudinally arranged drive wheels 301 and driven wheels 302. The drive wheels 301 are located on the right side, and the driven wheels 302 are located on the left side. The driven wheels 302 are connected to a avoidance linear actuator 7, which is also a hydraulic cylinder. The driven wheels 302 are also mounted on the push plate 8. The distance between the driven wheels 302 and the drive wheels 301 can be adjusted by the avoidance linear actuator 7 to straighten the reinforcing bars, ensure that the reinforcing bars remain straight, and also avoid the sleeve.

[0035] In this embodiment, combined with Figure 1 As shown, the second forming mechanism 9 includes a wheel frame 901 connected to the integrated steel frame 1. A fixed wheel 902 and a pusher 903 are mounted on the wheel frame 901. A pusher wheel 904 is connected to the moving end of the pusher 903. The pusher 903 can drive the pusher wheel 904 towards the fixed wheel 902. The fixed wheel 902 and the pusher wheel 904 bend the reinforcing bar, achieving precise arc forming and further ensuring the quality of the ring reinforcement.

[0036] Combination Figure 1 and Figure 2 As shown, the drive motor 10 is mounted on the back of the integrated steel frame 1, and uses a high-power motor as the drive motor 10. The drive motor 10 is connected to a reducer 1001, which can reduce the speed and increase the torque. The reducer 1001 is connected to drive wheel 201 and drive wheel 301. A gearbox is mounted on the back of the integrated steel frame 1, and each gearbox is connected to a corresponding drive wheel 201 and drive wheel 301. Adjacent gearboxes are connected by a transmission rod, and the output shaft of the reducer 1001 is connected to the input shaft of the gearbox. This achieves synchronous drive of drive wheel 201 and drive wheel 301. It avoids the situation where drive wheel 201 and drive wheel 301 use two sets of power systems, which would cause asynchronous speeds and lead to significant mechanical vibration during the ring rib forming process.

[0037] Furthermore, in combination Figure 2As shown, the encoder 5 is mounted on the back of the integrated steel frame 1. Gear 1 is provided on the axle of the reducer 1001, and gear 2 is provided on the main shaft of the encoder 5. Gear 2 meshes with gear 1, and the transmission ratio is 1:1. Through this gear transmission connection, the rotation of the drive wheel 201 can be accurately transmitted to the encoder 5 so as to accurately measure the travel distance of the steel bar.

[0038] In this embodiment, combined with Figure 1 As shown, the matrix laser sensor 4 is installed on the rebar inlet side of the first forming mechanism 2, which can monitor the passing of the sleeve on the rebar in real time. The encoder 5 is connected to the drive wheel 201 by gear transmission, which can accurately measure the number of rotations of the drive wheel 201, and then calculate the travel distance of the rebar. Both the matrix laser sensor 4 and the encoder 5 are electrically connected to the control box 8, transmitting the monitoring and measurement data to the control box 8.

[0039] Combination Figure 1 As shown, the hydraulic station is connected to the first avoidance linear actuator 6 and the second avoidance linear actuator 7, providing them with hydraulic power. The hydraulic station is controlled by the control box 8, and adjusts the output pressure and flow according to the instructions of the control box 8 to control the movement of the first avoidance linear actuator 6 and the second avoidance linear actuator 7.

[0040] The working principle of this utility model's tunnel wall ring reinforcement forming device is as follows:

[0041] In actual operation, the steel bars are fed into the tunnel wall ring reinforcement forming device. The steel bars first pass through the first forming mechanism 2. The matrix laser sensor 4 monitors the position of the steel bar sleeve in real time. The encoder 5 accurately measures the travel distance of the steel bars. The drive wheel 201 drives the steel bars forward. The avoidance linear drive 6 adjusts the position of the driven wheel 202 to clamp the steel bars and at the same time avoids the sleeve.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
