Description

Technical Field

[0001] This utility model belongs to the field of shield tunnel steel bar processing technology, and more specifically, it relates to a bending device for processing shield tunnel segment steel bars. Background Technology

[0002] In the production of tunnel segments, a large number of curved steel bars are required to construct the skeletal structure of the segments. Therefore, a bending device for processing the steel bars in tunnel segments is needed to bend the steel bars. Existing bending devices for tunnel segment steel bars mainly consist of three parts: steel bar conveying, bending execution, and power drive. The steel bar conveying part typically comprises a conveyor frame that carries the steel bars, conveyor rollers with anti-slip surfaces, and a conveyor motor that provides power. The bending execution mechanism generally has a fixed base and a movable base, on which a bending mold with a shape adapted to the arc of the tunnel segment steel bars is mounted. The power drive structure provides power for steel bar conveying and bending operations.

[0003] Existing application CN202222314106.1 discloses a bending device for processing steel bars in tunnel segment reinforcement, belonging to the field of steel bar processing technology. It includes a main body, multiple traction rollers, a fixed frame on one side of the main body, and a container on another side of the fixed frame. Two holding plates are fixed inside the container; the side of the holding plates away from the ground is a placement chamber, and the side closer to the ground is a separation chamber. An entrance is opened in the side wall of the placement chamber, and a first through hole for steel bars to pass through is provided between the two holding plates. A separation mechanism is provided in the separation chamber, and a second through hole for steel bars to pass through is opened in the peripheral side wall of the separation chamber. A placement plate and a transmission assembly are arranged inside the fixed frame. A cylinder is installed on one side of the fixed frame, and the piston rod on the cylinder corresponds to the gap between the traction rollers, allowing the piston rod to abut against and engage with the steel bars. This application facilitates the transport of steel bars to the equipment by workers, thereby reducing the workload of workers.

[0004] Based on the above, existing bending devices for shield tunnel segment reinforcement processing require manual labor or robotic arms to transport the processed reinforcement to a storage location for centralized storage after bending. However, manual handling is not only time-consuming and labor-intensive, but also prone to human error as labor intensity increases. While robotic arms can improve handling efficiency, the cost of purchasing, installing, and maintaining them is high, placing a significant economic burden on enterprises. Furthermore, when the bent reinforcement is stacked for storage, its irregular shape easily creates large gaps between the reinforcements, resulting in ineffective utilization of storage space and wasted storage resources. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a bending device for processing steel reinforcement in tunnel lining segments. This solves the problem that existing bending devices for tunnel lining segments require manual labor or robotic arms to transport the processed steel reinforcement to a storage location for centralized storage after bending. Manual handling is not only time-consuming and labor-intensive, but also prone to human error as labor intensity increases. While robotic arms can improve handling efficiency, the cost of purchasing, installing, and maintaining them is high, placing a significant economic burden on enterprises. Furthermore, when the bent steel reinforcement is stacked for storage, its irregular shape easily leads to large gaps between the reinforcements, resulting in ineffective utilization of storage space and wasted storage resources.

[0006] The purpose and effectiveness of this utility model for bending arc devices in the processing of steel bars for tunnel segments are achieved by the following specific technical means:

[0007] A bending device for processing steel bars in tunnel boring machine segments includes a bending worktable, a steel bar conveying mechanism, a bending mechanism, an inclined conveying trough, a guide rail support, a storage rack, a storage mechanism, and a stacking mechanism. The steel bar conveying mechanism is located on the upper part of the bending worktable; the bending mechanism is located on the upper part of the bending worktable; the inclined conveying trough is formed inside the bending worktable; the guide rail support is fixedly installed on one side of the bending worktable; the storage rack is located in front of the inclined conveying trough; the storage mechanism is located inside the bending worktable; and the stacking mechanism is located inside the bending worktable.

[0008] Furthermore, the storage mechanism includes: lifting plates and electric push rods. Two sets of lifting plates are provided, and the two sets of lifting plates are located on the left and right sides of the bending mechanism. Two sets of electric push rods are provided, and the two sets of electric push rods are fixedly installed inside the bending worktable. The top ends of the two sets of electric push rods are fixedly installed at the bottom of the two sets of lifting plates.

[0009] Furthermore, the storage mechanism also includes a drive motor and a lead screw. The drive motor is fixedly installed on the top right side of the guide rail bracket. The lead screw is rotatably connected to the inner side of the upper part of the guide rail bracket, and one end of the lead screw is fixedly installed inside the drive motor.

[0010] Furthermore, the storage mechanism also includes: a transmission block, an electromagnet, and a movable roller. The transmission block is slidably connected to the inner side of the upper part of the guide rail bracket, and the transmission block is threadedly connected to the outer side of the threaded screw. The electromagnet is fixedly installed at the bottom of the transmission block, and the movable roller is fixedly installed at the bottom of the storage rack.

[0011] Furthermore, the stacking mechanism includes: a first sprocket, a drive shaft, and a second sprocket. The first sprocket is coaxially fixedly mounted on one end of a threaded screw. The drive shaft is rotatably connected inside the curved worktable. The second sprocket is coaxially fixedly mounted on one end of the drive shaft. The first sprocket and the second sprocket are connected together by a chain.

[0012] Furthermore, the stacking mechanism also includes: a transmission cam, a drive rod, and a transmission connecting rod. The transmission cam is fixedly installed at one end of the transmission shaft and is rotatably connected inside the curved worktable. The drive rod is slidably connected inside the curved worktable, and the top end of the drive rod is inserted into one side of the storage rack via a pin. One end of the transmission connecting rod is hinged to one side of the transmission cam, and the other end of the transmission connecting rod is hinged to the end of the drive rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, this utility model has a storage mechanism. The drive motor drives the screw to rotate, thereby moving the transmission block and causing the electromagnet to attract and grab the bent steel bar. Utilizing the inclined structure of the inclined conveying trough, the steel bar slides smoothly into the storage rack for centralized storage, making it convenient to collect and store the bent steel bar. Moreover, the structure is simple and the cost is low.

[0015] Secondly, this utility model has a stacking mechanism. The first sprocket is rotated synchronously by the rotation of the threaded screw, which drives the drive rod to slide back and forth through a series of parts, causing the storage rack to vibrate. Under the action of vibration, the steel bars inside the storage rack are constantly adjusted and gradually arranged closely, thereby reducing the gap between the steel bars and effectively utilizing the storage space inside the storage rack. Moreover, the storage rack and the drive rod are connected by a pin, which makes it easy to separate and move the storage rack.

[0016] This utility model has the advantages of being easy to use, easy to collect and store, and having a high space utilization rate. It facilitates the collection and storage of bent steel bars, and has a simple structure, low cost, and reduces the gap between steel bars, effectively utilizing the internal storage space of the storage rack.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a bending device for processing steel bars in tunnel segment reinforcement, including a bending workbench 1, a steel bar conveying mechanism 2, a bending mechanism 3, an inclined conveying trough 5, a guide rail support 6, a storage rack 7, and a storage mechanism. The steel bar conveying mechanism 2 is located on the upper part of the bending workbench 1; the bending mechanism 3 is located on the upper part of the bending workbench 1; the inclined conveying trough 5 is opened inside the bending workbench 1; the guide rail support 6 is fixedly installed on one side of the bending workbench 1; the storage rack 7 is located in front of the inclined conveying trough 5; and the storage mechanism is located inside the bending workbench 1.

[0029] The storage mechanism includes: lifting plate 4 and electric push rod 401. There are two sets of lifting plates 4, which are located on the left and right sides of the bending mechanism 3. There are two sets of electric push rod 401, which are fixedly installed inside the bending worktable 1. The top ends of the two sets of electric push rod 401 are fixedly installed at the bottom of the two sets of lifting plates 4.

[0030] The storage mechanism also includes a drive motor 601 and a lead screw 602. The drive motor 601 is fixedly installed on the top right side of the guide rail bracket 6. The lead screw 602 is rotatably connected to the upper inner side of the guide rail bracket 6, and one end of the lead screw 602 is fixedly installed inside the drive motor 601.

[0031] The storage mechanism also includes: a transmission block 603, an electromagnet 6031, and a moving roller 701. The transmission block 603 is slidably connected to the inner side of the upper part of the guide rail bracket 6, and the transmission block 603 is threadedly connected to the outer side of the threaded screw 602. The electromagnet 6031 is fixedly installed at the bottom of the transmission block 603. The moving roller 701 is fixedly installed at the bottom of the storage rack 7.

[0032] The specific usage and function of this embodiment are as follows: After the bending mechanism 3 completes the bending operation on the reinforcing bar, the electric push rod 401 is immediately activated, driving the lifting plate 4 to push upward from the surface of the bending workbench 1, smoothly lifting the bent reinforcing bar. At the same time, the drive motor 601 and the electromagnet 6031 are synchronously energized and operate. After the drive motor 601 starts operating, it drives the threaded screw 602 to start rotating. The threaded screw 602, with its threaded structure, drives the transmission block 603 that cooperates with it to move along the set trajectory. The movement of the transmission block 603 further drives the electromagnet 6031 installed on it to move synchronously. When the electromagnet 6031 moves to the position of the lifted reinforcing bar, it uses its magnetism to attract and grab the reinforcing bar. Subsequently, the transmission block 603 continues to move, dragging the attracted reinforcing bar to the inclined conveyor chute 5. At this time, the electromagnet 6031 is de-energized, and the demagnetized electromagnet 6031 releases the steel bar, allowing the steel bar to slide down along the inclined structure of the inclined conveyor chute 5 under the action of gravity and into the storage rack 7 for centralized storage. The movable rollers 701 facilitate the movement of the storage rack 7.

[0033] Example 2:

[0034] Based on Example 1, such as Figures 1 to 6 As shown, it also includes a stacking mechanism, which is located inside the curved worktable 1.

[0035] The stacking mechanism includes a first sprocket 604, a drive shaft 606, and a second sprocket 605. The first sprocket 604 is coaxially fixedly installed at one end of the threaded screw 602. The drive shaft 606 is rotatably connected inside the curved worktable 1. The second sprocket 605 is coaxially fixedly installed at one end of the drive shaft 606. The first sprocket 604 and the second sprocket 605 are connected together by a chain.

[0036] The stacking mechanism also includes: a transmission cam 607, a drive rod 609, and a transmission connecting rod 608. The transmission cam 607 is fixedly installed at one end of the transmission shaft 606 and is rotatably connected inside the curved worktable 1. The drive rod 609 is slidably connected inside the curved worktable 1, and the top end of the drive rod 609 is inserted into one side of the storage rack 7 through a pin. One end of the transmission connecting rod 608 is hinged to one side of the transmission cam 607, and the other end of the transmission connecting rod 608 is hinged to the end of the drive rod 609.

[0037] The specific usage and function of this embodiment are as follows: When the lead screw 602 starts to rotate, on the one hand, it drives the transmission block 603 to move in a predetermined direction through its threaded structure; on the other hand, it drives the first sprocket 604 connected to it to rotate synchronously. The first sprocket 604 is connected to the second sprocket 605 through a chain, transmitting power to it and causing the second sprocket 605 to rotate accordingly. The rotation of the second sprocket 605 drives the transmission shaft 606 connected to it to rotate. The rotation of the transmission shaft 606 then drives the transmission cam 607 to start to perform circular motion. As the transmission cam 607 rotates, its unique profile continuously pushes the transmission connecting rod 608, causing it to oscillate regularly. The oscillation of the transmission connecting rod 608 further drives the drive rod 609 to reciprocate within the curved worktable 1. The reciprocating sliding of the drive rod 609 is connected to the storage rack 7, causing the storage rack 7 to also reciprocate. This reciprocating movement causes the storage rack 7 to vibrate. Under the action of vibration, the steel bars inside the storage rack 7 continuously adjust their positions and gradually become more tightly packed, thereby reducing the gaps between the steel bars. The moving rollers 701 installed at the bottom of the storage rack 7 play a role in assisting support and smoothing the movement of the storage rack 7 during reciprocating movement, ensuring that the entire vibration process proceeds smoothly.
