Description

Technical Field

[0001] This application relates to the technical field of bridge construction auxiliary devices, and in particular to a continuous beam reinforcement alignment control device. Background Technology

[0002] A continuous beam typically refers to a beam with three or more supports. The steel reinforcement cage of a continuous beam includes multiple straight-arranged n-shaped steel bars. During the steel bar pre-embedding process, a large deviation in the pre-embedded position of the steel bars can lead to a situation where the formwork cannot be closed during the later installation of the continuous beam formwork.

[0003] Chinese Patent Publication No. CN218623401U discloses a continuous beam reinforcement alignment control device, including a support frame with at least one control unit. The control unit includes a first guide rod and a second guide rod. The first guide rod abuts against the top of the reinforcement cage, and the second guide rod abuts against the side wall of the reinforcement cage. In use, the top of the reinforcement bar abuts against the first guide rod on the support frame, and the side wall of the reinforcement bar abuts against the second guide rod, ensuring the straightness of the reinforcement cage after it is formed.

[0004] In related technologies, when the steel cage is limited by the first and second benchmarks, the steel cage needs to be placed under the corresponding control unit at fixed intervals and adjusted to abut against the first and second benchmarks. This can easily lead to a waste of time and affect installation efficiency. Summary of the Invention

[0005] To facilitate the limiting of each rebar cage and improve installation efficiency, this application provides a continuous beam rebar alignment control device.

[0006] The technical solution for the continuous beam reinforcement alignment control device provided in this application is as follows:

[0007] A continuous beam reinforcement alignment control device includes a frame and multiple limiting blocks installed on the frame and corresponding to the reinforcement cage. Each limiting block has a snap-fit ​​component on its lower side, and a spacing rod is provided between the limiting blocks. An adjusting frame is sleeved and slidably connected to the outside of the frame. Both sides of the frame are inserted into the adjusting frame. Vertical lead screws are threaded through and connected to both sides of the frame. The lead screws are rotatably connected to the adjusting frame, and a motor for driving the lead screws to rotate is provided on the adjusting frame.

[0008] By adopting the above technical solution, when limiting each rebar cage, the rebar cage is placed under the corresponding limiting block. At this time, the motor drives the lead screw to move the frame downward until the locking piece on the limiting block fixes the corresponding rebar cage. Then, the limiting block is driven to move so that the distance between the limiting blocks corresponds to the specified interval between the rebar cages. When the locking piece limits the rebar cage, it reduces the possibility of the rebar cage moving in the horizontal and vertical directions, thereby facilitating the limiting of each rebar cage and improving installation efficiency.

[0009] Optionally, the limiting block located at one end of the frame is fixedly connected to the frame, and the remaining limiting blocks are slidably connected to the frame along the length direction of the spacing rod. A cylinder for driving the limiting block to move is installed on the limiting block at the end of the frame away from the limiting block fixedly connected to the frame, and the cylinder is fixedly connected to the upper side of the frame.

[0010] By adopting the above technical solution, the cylinder drives the limiting block to move. When the limiting block moves to the edge of the spacing rod, the cylinder continues to drive the limiting block to move until the spacing rod between two adjacent limiting blocks is located outside the limiting block, so that the spacing between the steel cages is equal, which further facilitates the limiting of each steel cage and improves the installation efficiency.

[0011] Optionally, the snap-fit ​​component includes snap-fit ​​plates hinged to both ends of the limiting block and corresponding to both ends of the reinforcing cage. Hooks are provided at the lower ends of the snap-fit ​​plates on the sides that are close to each other. A driving component is provided on the limiting block to drive the snap-fit ​​plates to clamp the reinforcing cage.

[0012] By adopting the above technical solution, the driving component drives the snap-fit ​​plate to rotate along the hinge point in a direction that brings them closer to each other until the hooks on the snap-fit ​​plate clamp the two ends of the steel cage. This facilitates the movement of the steel cage and the adjustment of the distance between the steel cages, and makes it easier to limit the position of each steel cage, thereby improving the installation efficiency.

[0013] Optionally, the driving component includes a driving block inserted into the lower side of the limiting block and slidably connected to the limiting block. One end of the driving block inserted into the limiting block is hinged with two hinge rods. The ends of the hinge rods that are far apart from each other are inclined upwards in the direction of approaching each other, and the ends of the hinge rods that are far apart from each other are hinged to the upper end of the snap-fit ​​plate. Both ends of the limiting block are provided with fixing components.

[0014] By adopting the above technical solution, the screw drives the frame to move downward until the drive block abuts against the upper side of the rebar cage. The frame continues to move downward, at which point the upper side of the rebar cage pushes the drive block upward and causes the hinge rod to rotate away from each other along the hinge point. At this time, the clamping plate hinged to the hinge rod rotates towards each other and clamps the rebar cage. The clamping plate is fixed by the fastener, which facilitates the movement of the rebar cage and the adjustment of the distance between the rebar cages, thereby improving the adjustment efficiency.

[0015] Optionally, the fixing member includes a ratchet rotatably connected to the hinge point of the snap-fit ​​plate and the limiting block, the ratchet being fixedly connected to the snap-fit ​​plate, and a pawl that engages with the ratchet being hinged on the limiting block.

[0016] By adopting the above technical solution, when the snap-fit ​​plate rotates, the ratchet rotates with the snap-fit ​​plate. At this time, the pawl limits the rotation direction of the ratchet, reducing the possibility that the snap-fit ​​plate will rotate and detach from the steel cage under the weight of the steel cage, and improving the stability of the steel cage during adjustment.

[0017] Optionally, a spring is fixedly connected to the upper side of the drive block, and the other end of the spring is fixedly connected to the inner wall of the limiting block.

[0018] By adopting the above technical solution, when the drive block moves upward, the spring is compressed. After the steel cage is tied, the drive pawl disengages from the ratchet. At this time, the spring restores its deformation and pushes the drive block to move away from the limit block, which facilitates the drive frame to disengage from the steel cage and facilitates disassembly.

[0019] Optionally, the lower side of the limiting block is configured as an arc shape adapted to the reinforcing cage.

[0020] By adopting the above technical solution, when the reinforcing cage is installed on the lower side of the limiting block, the arc-shaped surface increases the contact area between the limiting block and the reinforcing cage, thereby improving the stability of the reinforcing cage during lifting.

[0021] Optionally, rubber pads are fixedly connected to the sides of the snap-fit ​​plates that are close to each other.

[0022] By adopting the above technical solution, the rubber pad increases the friction between the clamping plate and the reinforcing cage, thereby improving the stability of the reinforcing cage during lifting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Place the rebar cage under the corresponding limit block. At this time, the motor drives the lead screw to move the frame downward until the locking piece on the limit block fixes the corresponding rebar cage. Then, drive the limit block to move so that the distance between the limit blocks corresponds to the specified interval between the rebar cages. When the locking piece limits the rebar cage, it reduces the possibility of the rebar cage moving in the horizontal and vertical directions, thus making it easier to limit each rebar cage and improve installation efficiency.

[0025] 2. The cylinder drives the limit block to move. When the limit block moves to the edge of the limit block, the cylinder continues to drive the limit block to move until the spacing rod between two adjacent limit blocks is located outside the limit block, so that the spacing between the steel cages is equal, which further facilitates the limiting of each steel cage and improves the installation efficiency.

[0026] 3. The screw drives the frame to move downwards until the drive block abuts against the upper side of the rebar cage. Continue to drive the frame downwards. At this time, the upper side of the rebar cage pushes the drive block upwards, causing the hinge rod to rotate away from each other along the hinge point. At this time, the clamping plate hinged to the hinge rod rotates towards each other and clamps the rebar cage. The clamping plate is fixed by the fastener, which facilitates the movement of the rebar cage and the adjustment of the distance between the rebar cages, thus improving the adjustment efficiency.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a device for controlling the reinforcement alignment of continuous beams. (Refer to...) Figure 1 and Figure 2A continuous beam reinforcement alignment control device includes a horizontal frame 1. Multiple limiting blocks 2 are arranged along the width direction of the frame 1 on its lower side; in this embodiment, three are used. The lower side of each limiting block 2 is designed in an arc shape to fit the reinforcement cage. A horizontal spacing rod 21 is inserted into and slidably connected between adjacent limiting blocks 2. The limiting block 2 located on one side of the frame 1 is fixedly connected to the frame 1, while the remaining limiting blocks 2 are inserted into and slidably connected to the frame 1.

[0033] Reference Figure 1 and Figure 2 A mounting block 22 is fixedly connected to the upper end of the limiting block 2 on the side away from the frame 1. The mounting block 22 passes through the frame 1 and is slidably connected to the frame 1. A cylinder 23 is fixedly connected to the upper side of the frame 1 along the length direction of the frame 1. The telescopic rod of the cylinder 23 is fixedly connected to the mounting block 22. Each limiting block 2 is provided with a clamping part 3 for clamping the reinforcing cage. An adjusting frame 4 is sleeved and slidably connected to the outer wall of the frame 1. Adjusting plates are fixedly connected to both ends of the frame 1 in the width direction. The adjusting plates are inserted into the inner wall of the adjusting frame 4 and are slidably connected to the adjusting frame 4. A vertical lead screw 41 is rotatably connected to each adjusting frame 4. The lead screw 41 passes through the adjusting plate and is threadedly connected to the adjusting plate. A motor 42 for driving the lead screw 41 to rotate is fixedly connected to the upper side of the adjusting frame 4.

[0034] When limiting each rebar cage, the rebar cage is placed below the corresponding limiting block 2. At this time, the motor 42 drives the lead screw 41 to move the frame 1 downward until the snap-fit ​​3 on the limiting block 2 fixes the corresponding rebar cage. The cylinder 23 drives the limiting block 2 to move. When the limiting block 2 moves to the edge of the spacing rod 21, the limiting block 2 continues to move until the spacing rod 21 between two adjacent limiting blocks 2 is located outside the limiting block 2, so that the interval between the rebar cages is equal, and the rebar cage limiting is completed.

[0035] When the reinforcing cage is installed under the limiting block 2, the arc-shaped surface increases the contact area between the limiting block 2 and the reinforcing cage, and the rubber pad increases the friction between the clamping plate 32 and the reinforcing cage, thereby improving the stability of the reinforcing cage during lifting.

[0036] Reference Figure 1 and Figure 3 The snap-fit ​​component 3 includes a horizontal mounting plate 31 fixedly connected to the end of the limiting block 2. Each mounting plate 31 has a snap-fit ​​plate 32 hinged to its opposite ends, perpendicular to the mounting plate 31. The lower ends of the snap-fit ​​plates 32 on their adjacent sides are provided with hooks, and rubber pads (not shown in the figure) are fixedly connected to the adjacent sides of the snap-fit ​​plates 32. A drive component 5 is provided on the lower side of the limiting block 2 to drive the snap-fit ​​plates 32 to rotate in the direction of approaching each other.

[0037] Reference Figure 2 and Figure 3 The driving component 5 includes a driving block 51 that is inserted into and slidably connected to the lower side of the limiting block 2. Two hinge rods 52 are hinged to the upper side of the driving block 51. The ends of the hinge rods 52 that are far apart from each other pass through the end of the limiting block 2 and are inclined upward. The ends of the hinge rods 52 that are far apart from each other are hinged to the upper end of the snap-fit ​​plate 32, and the mounting plate 31 is provided with a fixing member 6.

[0038] Reference Figure 3 The fastener 6 includes a ratchet 61 located at the hinge point of the snap-fit ​​plate 32 and the mounting plate 31 and fixedly connected to the snap-fit ​​plate 32. The mounting plate 31 is hinged with pawls 62 that engage with the ratchet 61. A spring 63 is fixedly connected to the upper side of the drive block 51. The other end of the spring 63 is fixedly connected to the limit block 2.

[0039] The upper side of the rebar cage pushes the drive block 51 upward and causes the hinge rod 52 to rotate away from each other along the hinge point. At this time, the clamping plate 32, which is hinged to the hinge rod 52, rotates towards each other and clamps the rebar cage. When the clamping plate 32 rotates, the ratchet 61 rotates with the clamping plate 32. At this time, the pawl 62 limits the rotation direction of the ratchet 61. At this time, the spring 63 is compressed. After the rebar cage is tied, the drive pawl 62 disengages from the ratchet 61. At this time, the spring 63 restores its deformation and pushes the drive block 51 to move away from the limit block 2, so that the drive frame 1 can disengage from the rebar cage.

[0040] The implementation principle of the continuous beam reinforcement line control device in this application embodiment is as follows: the reinforcement cage is placed below the corresponding limiting block 2. At this time, the motor 42 drives the lead screw 41 to move the frame 1 downward until the snap-fit ​​plate 32 on the limiting block 2 fixes the corresponding reinforcement cage. The cylinder 23 drives the limiting block 2 to move. When the limiting block 2 moves to the edge of the spacing rod 21, the limiting block 2 continues to move until the spacing rod 21 between two adjacent limiting blocks 2 is located outside the limiting block 2, so that the interval between the reinforcement cages is equal, and the reinforcement cage is limited.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
