Description

Technical Field

[0001] This utility model relates to the field of steel cage welding technology, and in particular to a device for rolling steel cages. Background Technology

[0002] Reinforcing cages are a type of reinforced concrete structure widely used in building construction, especially in pile foundation engineering. A reinforcing cage consists of longitudinal reinforcing bars (main bars), transverse reinforcing bars (stirrups), and positioning bars. The main reinforcing bars typically bear axial tensile or compressive forces and are the primary load-bearing reinforcement; their diameter is usually relatively large, determined based on engineering design requirements and load-bearing capacity calculations. Whether in the pile foundations of high-rise buildings or industrial plants, reinforcing cages are an indispensable component. In cast-in-place pile construction, the reinforcing cage is first lowered into the pile hole, and then concrete is poured in to form a reinforced concrete cast-in-place pile.

[0003] In the existing technology, when welding the ear bars of the rebar cage, the rebar cage needs to be rolled on the ground. Due to the excessive weight of the rebar cage itself, it often requires three to four workers to roll it, which results in a waste of manpower. Therefore, rebar cage rolling devices are usually used to assist the workers. However, different rebar cages have different diameters, and the distance between the two rollers in some existing rebar cage rolling devices is constant, making it difficult to help rebar cages of different diameters roll, thus reducing the scope of application. Utility Model Content

[0004] The purpose of this invention is to address the problem that in existing technologies, different rebar cages have different diameters, and the distance between the two rollers in some existing rebar cage rolling devices is constant, making it difficult to roll rebar cages of different diameters and reducing their applicability. Therefore, this invention proposes a device for rolling rebar cages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for rolling a steel cage, comprising a fixed frame, wherein there are several fixed frames, two first movable plates are slidably mounted on one end of each fixed frame, two second movable plates are slidably mounted on the end of each fixed frame away from the first movable plates, two second rollers are rotatably mounted between the first movable plates and the second movable plates, two second through holes are provided through the outer walls of both the first and second movable plates, and multiple evenly distributed first through holes are provided through both ends of the interior of each fixed frame, two connecting plates are provided on the exterior of one of the several fixed frames, the two connecting plates are respectively connected to the two first movable plates by bolts, an L-shaped plate is fixedly mounted on the outer wall of the connecting plate, a motor is fixedly mounted on the top of the L-shaped plate, and the output end of the motor passes through the L-shaped plate and is fixedly mounted on the first roller.

[0006] Preferably, the inner sidewall of the fixing frame has multiple evenly distributed positioning openings.

[0007] Preferably, the outer wall of the first movable plate has an opening, a U-shaped plate is fixedly installed at one end of the first movable plate, a spring is fixedly connected to the inner wall of the U-shaped plate, a locking block is fixedly installed at one end of the spring, a storage groove is opened at the end of the locking block away from the spring, a second roller is rotatably installed inside the storage groove, a connecting rod is fixedly installed at the end of the locking block near the spring, and a pull plate is fixedly installed at one end of the connecting rod through the U-shaped plate.

[0008] Preferably, a support plate is fixedly installed between the first movable plate and the second movable plate, and the bottom of the support plate has four evenly distributed first rollers.

[0009] Preferably, the top of the fixing frame has two sets of fixing holes.

[0010] Preferably, the opposite sides of the first movable plate and the second movable plate are respectively attached to the outer sides of the fixed frame.

[0011] Preferably, the outer wall of the card block is in contact with the inner wall of the positioning port.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during adjustment, the worker removes the bolts from the first through hole and the second through hole, and then pulls the first moving plate so that the two first moving plates inside the same fixed frame move away from each other. When the distance between the two first moving plates is the required distance, the worker uses bolts to pass through the first through hole and the second through hole to connect the first moving plate to the fixed frame. Finally, the worker installs the connecting plate on the outer wall of the first moving plate at the edge with bolts, and the first roller is placed between the two second rollers. This completes the adjustment, which is convenient for adjusting the distance between the two first rollers according to the steel cages of different diameters, thus improving the range of applications.

[0014] 2. In this utility model, during adjustment, the operator pulls the pull plate, which drives the locking block to move through the connecting rod. The locking block leaves the positioning port. Then, the operator moves the first moving plate. When it is about to move to the desired position, the operator releases the pull plate. The spring pushes the locking block to move, and the second roller contacts the outer wall of the fixed frame. The operator continues to push the first moving plate until the locking block enters the positioning port. At this time, the second through hole moves to the side of the first through hole, which facilitates positioning and bolt installation. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figures 1-4 As shown, this utility model provides a device for rolling a rebar cage, including a fixed frame 1. There are several fixed frames 1. Two first moving plates 2 are slidably installed at one end of each fixed frame 1. Two second moving plates 3 are slidably installed at the end of the fixed frame 1 away from the first moving plates 2. Two second rollers 11 are rotatably installed between the first moving plates 2 and the second moving plates 3. Two second through holes 14 are opened through the outer walls of the first moving plates 2 and the second moving plates 3. Multiple evenly distributed first through holes 7 are opened through both ends of the interior of the fixed frame 1. Two connecting plates 10 are provided on the outside of one of the several fixed frames 1. The two connecting plates 10 are respectively connected to the two first moving plates 2 by bolts. An L-shaped plate 4 is fixedly installed on the outer wall of the connecting plate 10. A motor 5 is fixedly installed on the top of the L-shaped plate 4. The output end of the motor 5 passes through the L-shaped plate 4 and is fixedly installed with the first roller 6.

[0023] The effect achieved by the entire embodiment 1 is as follows: During adjustment, the worker removes the bolts from the first through hole 7 and the second through hole 14, and then pulls the first moving plate 2 so that the two first moving plates 2 inside the same fixed frame 1 move away from each other. When the distance between the two first moving plates 2 is the required distance, the worker uses bolts to pass through the first through hole 7 and the second through hole 14 to connect the first moving plate 2 to the fixed frame 1. Finally, the worker installs the connecting plate 10 on the outer wall of the first moving plate 2 at the edge with bolts, and the first roller 6 is placed between the two second rollers 11. In this way, the adjustment can be completed, which makes it convenient to adjust the distance between the two first rollers 6 according to the steel cages of different diameters, thus improving the range of applications.

[0024] Example 2, as Figures 1-4 As shown, furthermore, the inner sidewall of the fixing frame 1 is provided with multiple evenly distributed positioning holes 8.

[0025] Furthermore, an opening 16 is provided through the outer wall of the first movable plate 2, a U-shaped plate 15 is fixedly installed at one end of the first movable plate 2, a spring 17 is fixedly connected to the inner wall of the U-shaped plate 15, a locking block 18 is fixedly installed at one end of the spring 17, a storage groove 19 is provided at the end of the locking block 18 away from the spring 17, a second roller 20 is rotatably installed inside the storage groove 19, a connecting rod 21 is fixedly installed at the end of the locking block 18 close to the spring 17, and a pull plate 22 is fixedly installed at one end of the connecting rod 21 through the U-shaped plate 15.

[0026] Furthermore, a support plate 12 is fixedly installed between the first movable plate 2 and the second movable plate 3, and the bottom of the support plate 12 has four evenly distributed first rollers 13.

[0027] Furthermore, the top of the mounting bracket 1 has two sets of mounting holes 9.

[0028] Furthermore, the opposite sides of the first movable plate 2 and the second movable plate 3 are respectively attached to the outer sides of the fixed frame 1. This prevents the first movable plate 2 and the second movable plate 3 from swaying left and right.

[0029] Furthermore, the outer wall of the locking block 18 fits into the inner wall of the positioning port 8. When the locking block 18 enters the positioning port 8, it can prevent the first moving plate 2 from shaking and prevent inaccurate positioning.

[0030] The effect achieved by the entire embodiment 2 is as follows: during adjustment, the operator pulls the pull plate 22, and the pull plate 22 drives the locking block 18 to move through the connecting rod 21. The locking block 18 leaves the positioning port 8. Then the operator moves the first moving plate 2. When it is about to move to the desired position, the operator releases the pull plate 22. The spring 17 pushes the locking block 18 to move. The second roller 20 contacts the outer wall of the fixed frame 1 and continues to push the first moving plate 2 until the locking block 18 enters the positioning port 8. At this time, the second through hole 14 moves to the side of the first through hole 7, which facilitates positioning and installation of bolts.

[0031] Working principle: In use, the worker places the rebar cage above the two first rollers 6, then starts the two motors 5. The output of the motors 5 drives the first rollers 6 to rotate, causing the first rollers 6 to roll the rebar cage, thus facilitating welding. For adjustment, the worker removes the bolts from the first through hole 7 and the second through hole 14, then pulls the first moving plate 2, moving the two first moving plates 2 inside the same fixed frame 1 away from each other. When the distance between the two first moving plates 2 is the desired distance, the worker uses bolts through the first through hole 7 and the second through hole 14 to connect the first moving plate 2 to the fixed frame 1. Finally, the worker installs the connecting plate 10 on the outer wall of the first moving plate 2 at the edge with bolts, and places the first roller 6 between the two second rollers 11. This completes the adjustment, allowing for convenient adjustment of the distance between the two first rollers 6 according to rebar cages of different diameters, thus improving the range of applications. During adjustment, the operator pulls the pull plate 22, which moves the locking block 18 through the connecting rod 21. The locking block 18 moves away from the positioning port 8. Then, the operator moves the first moving plate 2. When it is about to move to the desired position, the operator releases the pull plate 22. The spring 17 pushes the locking block 18 to move, and the second roller 20 contacts the outer wall of the fixing frame 1. The first moving plate 2 is pushed until the locking block 18 enters the positioning port 8. At this time, the second through hole 14 moves to the side of the first through hole 7 for easy positioning and easy installation of bolts.
