Description

Technical Field

[0001] This utility model relates to the field of steel cage construction technology, and in particular to an auxiliary device for the construction of spiral stirrups in steel cages. Background Technology

[0002] In pile foundation construction, construction sites are widely distributed, with some locations being remote, which poses a significant challenge to the transportation of cage rolling machines. As a crucial piece of equipment for manufacturing steel cages, the long-distance transportation of cage rolling machines not only involves high transportation costs but also carries the risk of equipment damage due to bumps and improper handling during transport, increasing additional maintenance costs and the risk of project delays.

[0003] Meanwhile, when the diameter of the reinforcing cage is small, the manual winding of spiral stirrups reveals many drawbacks. From the perspective of material properties, finished coiled steel itself has a certain degree of rigidity and elasticity, and each coil has a relatively large diameter. When manually winding the stirrups within the narrow diameter of the reinforcing cage, construction workers need to spend a lot of time and energy bending and adjusting the steel to fit the main reinforcement bars, which undoubtedly consumes a lot of manpower and leads to a significant reduction in construction efficiency.

[0004] Furthermore, during manual winding, it is difficult to ensure a tight fit between the spiral stirrups and the main reinforcement bars. Due to the limited precision of manual operation, coupled with factors such as the springback of the steel during winding, gaps are very likely to appear between the spiral stirrups and the main reinforcement bars. These gaps not only affect the overall structural strength of the reinforcement cage and reduce the bearing capacity of the pile foundation, but may also prevent the concrete from fully filling the gaps during subsequent concrete pouring, forming voids or defects, thus affecting the durability and stability of the pile foundation.

[0005] Based on the above-mentioned technical problems, this utility model provides an auxiliary device for the construction of spiral stirrups in steel cages. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figure 1-3 This utility model provides an auxiliary device for the construction of spiral stirrups in steel cages, comprising:

[0036] Construction platform 1, with mounting bracket 2 installed on one side of construction platform 1;

[0037] The bending machine includes an adjustable diameter support frame and a transmission assembly. The adjustable diameter support frame is rotatably connected to the top surface of the work platform 1, and the transmission assembly is installed at the bottom of the work platform 1. The transmission assembly and the adjustable diameter support frame are in a transmission engagement.

[0038] The guide assembly includes two sets of straightening pulleys 3, which are fixed at both ends of the mounting frame 2 and staggered between them. The straightening pulleys 3 are used to guide and straighten the stirrups.

[0039] The stirrup ends pass through two sets of straightening pulleys 3 in sequence and are fixed to an adjustable diameter support frame. The stirrup ends enter from above the first set of straightening pulleys 3 and exit from below the second set of straightening pulleys 3. The two sets of straightening pulleys 3 position the stirrups. During the winding process, the stirrups pass through the grooves of the upper pulley sets of the straightening pulleys 3. The pulling process straightens the stirrups. At the same time, the upper pulley sets of the two sets of straightening pulleys 3 and related rigging are used to position the stirrups, ensuring that they can be fed within the predetermined track.

[0040] In operation, the auxiliary device for constructing spiral stirrups in the reinforcing cage is placed in a suitable working position to ensure the stability of the construction platform 1. The adjustable diameter support frame in the bending machine is adjusted to the appropriate size according to the required stirrup diameter and rotatably connected to the top surface of the construction platform 1. At the same time, the transmission component is installed at the bottom of the construction platform 1 and establishes a transmission relationship with the adjustable diameter support frame to ensure that the transmission component can drive the adjustable diameter support frame to rotate.

[0041] The ends of the stirrups are passed sequentially through the two sets of straightening pulleys 3 installed at both ends of the mounting frame 2. Due to the staggered arrangement of the two sets of straightening pulleys 3, the stirrups will form a certain bending guide path during the passage, which helps the stirrups to wrap around the adjustable diameter support frame later. After that, the ends of the stirrups that have passed through the straightening pulleys 3 are fixed to the adjustable diameter support frame.

[0042] The transmission assembly is activated, causing the adjustable diameter support frame to rotate. As the adjustable diameter support frame rotates, the stirrups, guided by the guide assembly, continuously wind around the circumference of the adjustable diameter support frame, thus forming a spiral stirrup structure. During the winding process, the diameter of the adjustable diameter support frame can be adjusted as needed to change the diameter of the spiral stirrups, meeting the construction requirements of different rebar cages.

[0043] Once the stirrup has been wound to the required length, stop the transmission assembly and remove the stirrup from the adjustable diameter support frame, completing the processing of one section of the spiral stirrup. Repeat the above steps to process other spiral stirrups.

[0044] The design was further optimized. The construction platform 1 includes a top plate and side plates. There are four sets of side plates, which are symmetrically fixed to the bottom surface of the top plate in pairs. The mounting frame 2 is fixed to one side of the top plate.

[0045] Further optimization of the design includes an adjustable diameter support frame, which includes:

[0046] Turntable 4 is rotatably connected to the top surface of the top plate;

[0047] The horizontal moving seat 5 is provided in three sets. The three sets of horizontal moving seats 5 are arranged at equal intervals around the top surface of the turntable 4 and slide in cooperation with the turntable 4.

[0048] Mounting shaft 6 is vertically and coaxially fixed on turntable 4, and the bottom of mounting shaft 6 passes through the top plate;

[0049] The vertical moving seat 7 is vertically slidably connected to the mounting shaft 6. The vertical moving seat 7 and the horizontal moving seat 5 are arranged in a one-to-one correspondence. A connecting rod 8 is provided between the vertical moving seat 7 and the horizontal moving seat 5. The connecting rod 8 is rotatably connected to the vertical moving seat 7 and the horizontal moving seat 5.

[0050] Adjusting head 9 is threadedly connected to the top of mounting shaft 6, and is rotatably connected to vertical moving seat 7;

[0051] A spring is sleeved on the mounting shaft 6 and positioned between the vertical moving seat 7 and the turntable 4.

[0052] To further optimize the design, a groove is provided on the top surface of the turntable 4, with the axis of the groove coinciding with the radius of the turntable 4. A slider is fixedly connected to the bottom surface of the horizontal moving seat 5, and the slider is slidably connected within the groove.

[0053] When it is necessary to adjust the diameter of the spiral stirrup, the adjusting head 9 is rotated. Since the adjusting head 9 is threaded to the top of the mounting shaft 6 and rotatably connected to the vertical moving seat 7, rotating the adjusting head 9 will cause it to move up and down on the mounting shaft 6.

[0054] The vertical moving seat 7 and the horizontal moving seat 5 are rotatably connected by a connecting rod 8. When the vertical moving seat 7 moves up and down, it will drive the connecting rod 8 to move, thereby pushing or pulling the horizontal moving seat 5 to slide on the turntable 4.

[0055] The top surface of the turntable 4 is provided with a sliding groove, the axis of which coincides with the radius of the turntable 4. The slider on the bottom surface of the horizontal moving seat 5 is slidably connected in the sliding groove, ensuring that the horizontal moving seat 5 can slide stably along the radius of the turntable 4.

[0056] Three sets of horizontal moving seats 5 are arranged at equal intervals around the top surface of the turntable 4. By adjusting the up and down movement of the head 9, the three sets of horizontal moving seats 5 can be moved inward or outward simultaneously, thereby changing the diameter of the adjustable diameter support frame to meet the processing requirements of spiral stirrups of different diameters.

[0057] The spring is sleeved on the mounting shaft 6 and located between the vertical moving seat 7 and the turntable 4. The spring acts as a buffer and reset mechanism. During adjustment, the spring can balance the force on the vertical moving seat 7, making the adjustment process smoother. After adjustment, the spring can help the vertical moving seat 7 maintain a stable position and prevent changes in diameter due to vibration or other reasons.

[0058] The scheme is further optimized. The transmission components include a drive motor 10 and a speed regulator 11. Both the drive motor 10 and the speed regulator 11 are fixed on the side plate. The output shaft of the drive motor 10 is fixed to the input shaft of the speed regulator 11. The output shaft of the speed regulator 11 is fixed with a drive sprocket 12. The bottom of the mounting shaft 6 is fixedly connected to a driven sprocket. The drive sprocket 12 and the driven sprocket are driven by a chain 13. The drive motor 10 is connected to the controller for controlling the start and stop.

[0059] Further optimization of the design resulted in the diameter of the drive sprocket 12 being smaller than that of the driven sprocket.

[0060] When the drive motor 10 starts, its output shaft drives the input shaft of the speed controller 11 to rotate. After the speed controller 11 adjusts the speed of the motor, it drives the drive sprocket 12 to rotate through the output shaft.

[0061] Since the drive sprocket 12 and the driven sprocket are driven by the chain 13, the rotation of the drive sprocket 12 will drive the driven sprocket to rotate, which in turn will cause the mounting shaft 6 to rotate. The mounting shaft 6 is fixed coaxially with the turntable 4. The rotation of the mounting shaft 6 drives the turntable 4 to rotate, thereby realizing the rotation of the adjustable diameter support frame and providing power for the winding of the stirrups.

[0062] The drive motor 10 is connected to the controller, which can conveniently control the start and stop of the drive motor 10, thereby achieving precise control of the stirrup winding process.

[0063] The diameter of the drive sprocket 12 is smaller than that of the driven sprocket. This sprocket transmission ratio design can reduce speed and increase torque. The high-speed, low-torque power output by the drive motor 10 is converted into low-speed, high-torque power after passing through the sprocket transmission. This enables the adjustable diameter support frame to stably drive the hoop winding, and also helps to improve the transmission efficiency and reliability of the device.
