Description

Technical Field

[0001] This utility model relates to the field of power facility construction equipment technology, and in particular to a device for fabricating steel reinforcement cages for utility poles. Background Technology

[0002] This technology is mainly applicable to the automated fabrication of steel cages in cylindrical concrete structures of power poles and communication towers. It can be applied in precast component factories and construction sites. Compared with traditional manual fabrication methods, the pole steel cage fabrication device has the advantages of high production efficiency, high manufacturing precision, and stable product quality. It can greatly reduce the intensity of manual labor, improve production efficiency, and at the same time ensure that the quality of the steel cage meets relevant standards and engineering requirements.

[0003] A search revealed Chinese patent publication number CN222036673U, which discloses a device for manufacturing steel reinforcement cages for utility poles. The device includes a cage-rolling mechanism and a reinforcement feeding mechanism. The reinforcement feeding mechanism comprises a moving guide rail, on which a support platform and a power device for moving the support platform are mounted. The support platform is equipped with stirrup coils and a straightener for rebar delivery. The straightener includes several pairs of straightening rollers, each with a positioning groove. An installation part is located at the front of the support platform, and several adjustable rollers are mounted on the installation part. Each adjustable roller has a positioning groove for engaging with the stirrups of the steel reinforcement cage. The adjustable rollers are equidistantly distributed along the length of the moving guide rail. The cage-rolling mechanism includes two rollers for supporting the steel reinforcement cage. The two rollers are parallel and at the same height, and the two rollers are connected to the power device. This invention has the advantages of convenient operation, accurate positioning, and low cost.

[0004] While existing equipment can automate the fabrication of steel cages, it lacks the function of controlling the straightness of the steel cage along its length, which can easily lead to eccentricity problems during the centrifugal casting of utility poles. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a device for manufacturing steel reinforcement cages for utility poles, which aims to address the technical gap in the means of actively controlling the straightness of steel reinforcement cages.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pole reinforcement cage manufacturing device, comprising a support, a first driver slidably connected to the left side of the support, a third driver fixedly connected to the top of the support, a second driver fixedly connected to the left side of the inner wall of the support, a fourth driver fixedly connected to the right side of the inner wall of the support, a rotating disk rotatably connected to the front side of the inner wall of the third driver, six mechanical grippers fixedly connected to the front side of the inner wall of the rotating disk, a stirrup coil provided on the front side of the third driver, multiple main reinforcing bars provided between the first driver and the fourth driver, an external toothed ring fixedly provided on the front side of the inner wall of the fourth driver, multiple first straightening rollers and multiple second straightening rollers rotatably connected to the rear side of the inner wall of the fourth driver, gears fixedly connected to the front side of each of the multiple first straightening rollers, and an adjustment component provided on the inner wall of the fourth driver.

[0007] The above technical solution involves setting a fourth driver to drive the first and second straightening rollers to rotate before adding stirrups to the main reinforcement bars, thereby straightening the main reinforcement bars inserted in the fourth driver and adjusting the straightness of the steel cage.

[0008] As a further description of the above technical solution: the adjustment component includes a connecting block, which is fixedly connected to the fourth driver. Worm gears are fixedly connected to the front sides of both the first straightening roller and the second straightening roller. Cylinders are evenly distributed on the outer surface of the connecting block. A connecting member is fixedly connected to the output end of the cylinder. A connecting rod is rotatably connected to the outer surface of the connecting member. A first worm gear is fixedly connected to the outer surface of the connecting rod. A second worm gear is slidably connected to the outer surface of the connecting rod.

[0009] The above technical solution involves setting a connector and a cylinder in the fourth driver. The cylinder pushes the connector, which in turn moves the second worm and the inner worm wheel, causing the second straightening roller to move. This allows the gap between the first and second straightening rollers to be adjusted according to the size of the main rib, thereby achieving adaptive adjustment when processing main ribs of different sizes.

[0010] As a further description of the above technical solution: a plurality of locking teeth are fixedly connected to the rear side of the inner wall of the first driver, and a plurality of feeding wheels are fixedly connected to the rear side of the inner wall of the second driver. The locking teeth, feeding wheels, first straightening roller and second straightening roller are all in close contact with the main rib.

[0011] The above technical solution involves a number of clamping teeth and feeding wheels that correspond to the number of main ribs. When the feeding wheels push the main ribs to move, the clamping teeth fix the main ribs to move on the support, thereby realizing the movement of the main ribs.

[0012] As a further description of the above technical solution: the engagement size of the locking teeth and the feeding wheel can be adjusted by the first driver and the second driver, respectively.

[0013] The above technical solution involves adjusting the engagement degree by driving the locking teeth and feeding wheels. When the main ribs of different sizes are replaced, the locking teeth and feeding wheels can also lock the main ribs after adjustment, thereby achieving the adaptation to main ribs of different sizes.

[0014] As a further description of the above technical solution: the stirrup roll is fixedly connected to the bracket, and the stirrups on the stirrup roll are tightly fitted with the mechanical grippers.

[0015] The above technical solution achieves the purpose of uniformly and tightly wrapping the stirrups around the outer surface of the main reinforcement by rotating the mechanical gripper around the main reinforcement under the drive of the rotating disk.

[0016] As a further description of the above technical solution: the gear is meshed with the external gear ring, and when the external gear ring is driven by the fourth driver, multiple gears are driven to rotate.

[0017] The above technical solution achieves the purpose of straightening the main ribs by rotating the external gear ring to drive multiple gears to rotate, and simultaneously rotating the first straightening roller.

[0018] As a further description of the above technical solution: the worm gear is meshed with both the first worm and the second worm, and the connecting member is rotatably connected with both the second worm and the gear on the inner ring.

[0019] With the above technical solution: when the first straightening roller rotates, its front worm gear is driven to rotate. Through the cooperation of the worm gear, the first worm, and the second worm support, the second straightening roller is also driven to rotate. The connecting piece is rotated with the second worm and the gear in the inner ring, so that the normal operation is not affected when the distance between the first straightening roller and the second straightening roller can be adjusted.

[0020] As a further description of the above technical solution: the connecting rod is disposed between the connecting block and the fourth driver, and the connecting rod is rotatably connected to both the connecting block and the fourth driver.

[0021] The above technical solution involves rotating the connecting rod within the fourth driver, which synchronizes the first and second straightening rollers while simultaneously adjusting the position of the second straightening roller through a sliding connection with the second worm gear.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting a fourth driver on the far right of the support, when the main reinforcement enters the fourth driver, the first straightening roller and the second straightening roller corresponding to the number of main reinforcements rotate under the drive of the outer toothed ring to straighten the main reinforcement, thereby preventing losses caused by the bending of the main reinforcement and solving the technical gap in the means of active control of the straightness of the steel cage.

[0024] 2. In this utility model, by setting an adjustment component inside the fourth driver, when facing main ribs of different sizes, the cylinder drives the second worm, the inner worm wheel and the second straightening roller to move inward or outward on the connecting rod, thereby adjusting the pressing distance between the first straightening roller and the second straightening roller, solving the problem of mismatch of straightening rollers when processing different main ribs.

[0032] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides a device for manufacturing steel reinforcement cages for utility poles, comprising a support 1, a first driver 2 slidably connected to the left side of the support 1, a third driver 7 fixedly connected to the top of the support 1, a second driver 5 fixedly connected to the left side of the inner wall of the support 1, a fourth driver 11 fixedly connected to the right side of the inner wall of the support 1, a rotating disk 9 rotatably connected to the front side of the inner wall of the third driver 7, six mechanical grippers 10 fixedly connected to the front side of the inner wall of the rotating disk 9, a stirrup coil 8 provided on the front side of the third driver 7, multiple main reinforcing bars 4 provided between the first driver 2 and the fourth driver 11, an external toothed ring 15 fixedly provided on the front side of the inner wall of the fourth driver 11, multiple first straightening rollers 12 and multiple second straightening rollers 13 rotatably connected to the rear side of the inner wall of the fourth driver 11, gears 14 fixedly connected to the front side of each of the multiple first straightening rollers 12, and an adjustment component 16 provided on the inner wall of the fourth driver 11;

[0034] Specifically, the main reinforcing bar 4 to be processed is placed at the entrance of the fourth driver 11. During the process of entering the fourth driver 11, the main reinforcing bar 4 passes between the first straightening roller 12 and the second straightening roller 13. The fourth driver 11 drives the straightening roller to rotate and apply pressure to the main reinforcing bar 4, gradually straightening the bent main reinforcing bar 4. The straightened main reinforcing bar 4 enters the second driver 5. The second driver 5 drives the main reinforcing bar 4 to be conveyed to the left along the longitudinal guide rail on the support 1. The leftmost side of the main reinforcing bar 4 is fixed on the first driver 2. Under the push of the second driver 5, the first driver 2 moves on the support 1. At the same time as the main reinforcing bar 4 is fed, the third driver 7 starts to work. The stirrup plate is placed near the third driver 7. Six circumferentially distributed mechanical grippers 10 extend radially to grab the stirrup. The rotating disk 9 starts to rotate, driving the mechanical grippers 10 and the stirrup to move circumferentially together. As the rotating disk 9 rotates, the stirrup wraps around the main reinforcing bar 4 conveyed forward, completing the stirrup assembly process. This solves the technical gap in the means of active control of the straightness of the steel cage.

[0035] Reference Figures 3-4The adjusting component 16 includes a connecting block 1601, which is fixedly connected to the fourth driver 11. Worm gears 1605 are fixedly connected to the front sides of the first straightening roller 12 and the second straightening roller 13. Cylinders 1607 are evenly distributed on the outer surface of the connecting block 1601. A connecting piece 1606 is fixedly connected to the output end of the cylinder 1607. A connecting rod 1602 is rotatably connected to the outer surface of the connecting piece 1606. A first worm gear 1603 is fixedly connected to the outer surface of the connecting rod 1602. A second worm gear 1604 is slidably connected to the outer surface of the connecting rod 1602.

[0036] Specifically, when placing the main rib 4, the adjustment component 16, which is set in the inner wall of the fourth driver 11 and positioned between each set of straightening rollers, is used to push the second worm 1604 and the inner worm wheel 1605 outward by the cylinder 1607, thereby reducing the gap between the first straightening roller 12 and the second straightening roller 13, and vice versa, thus adapting to the size of the processed main rib 4 and solving the problem of mismatched straightening rollers when processing different main ribs 4.

[0037] Reference Figure 5 Multiple teeth 3 are fixedly connected to the rear side of the inner wall of the first driver 2, and multiple feeding wheels 6 are fixedly connected to the rear side of the inner wall of the second driver 5. The teeth 3, feeding wheels 6, first straightening roller 12 and second straightening roller 13 are all tightly fitted with the main rib 4.

[0038] Specifically, during the processing, the main rib 4 is inserted into the feed inlets of the first driver 2, the second driver 5, the third driver 7 and the fourth driver 11. When passing through the first driver 2 and the second driver 5, the main rib 4 is fixed and pushed by the clamping teeth 3 and the feeding wheel 6.

[0039] Reference Figure 5 The engagement size of the tooth 3 and the feeding wheel 6 can be adjusted by the first driver 2 and the second driver 5, respectively.

[0040] Specifically, the toothed teeth 3 and the feeding wheel 6 are each divided into twelve groups, the number of which corresponds to the number of main ribs 4. When the adjusting component 16 is adjusted according to the size of the main ribs 4, the toothed teeth 3 and the feeding wheel 6 are driven by the first driver 2 and the second driver 5 respectively to adjust the engagement degree.

[0041] Reference Figures 1-2 The stirrup coil 8 is fixedly connected to the support 1, and the stirrups on the stirrup coil 8 are tightly fitted with the mechanical gripper 10;

[0042] Specifically, the stirrups are stored on the outer surface of the stirrup coil 8. When the stirrups are installed, the mechanical gripper 10 adjusts the radial expansion and contraction in a timely manner according to the diameter requirements of the steel cage to ensure that the stirrups can be tightly wrapped around the main reinforcement 4.

[0043] Reference Figure 3The gear 14 is meshed with the external gear ring 15. When the external gear ring 15 is driven by the fourth driver 11, multiple gears 14 are driven to rotate.

[0044] Specifically, when the external gear ring 15 rotates, the connection between the gear 14 and the first straightening roller 12 causes the first straightening roller 12 to rotate, thereby straightening the main rib 4.

[0045] Reference Figure 4 The worm gear 1605 is meshed with the first worm 1603 and the second worm 1604, and the connecting piece 1606 is rotatably connected with the second worm 1604 and the gear 14 of the inner ring.

[0046] Specifically, when the first straightening roller 12 drives the worm gear 1605 on its front side to rotate, it drives the first worm 1603 to rotate, thereby driving the connecting rod 1602 and the second worm 1604 to rotate, thereby driving the inner ring gear 14 and the second straightening roller 13 to rotate. However, when the second worm 1604 and the inner ring gear 14 rotate, the connecting piece 1606 is not driven.

[0047] Reference Figure 4 The connecting rod 1602 is disposed between the connecting block 1601 and the fourth driver 11, and the connecting rod 1602 is rotatably connected to both the connecting block 1601 and the fourth driver 11.

[0048] Specifically, the connector 1606 is disposed between the connecting rod 1602, the connecting block 1601, and the fourth driver 11, and is connected to the first straightening roller 12 and the second straightening roller 13 through the first worm 1603 and the second worm 1604 disposed on the outer surface.

[0049] Working principle: During the processing of the rebar cage, the main reinforcing bar 4 is inserted into the feed inlets of the first driver 2, the second driver 5, the third driver 7, and the fourth driver 11. As it passes through the first driver 2 and the second driver 5, the main reinforcing bar 4 is fixed and pushed by the clamping teeth 3 and the feeding wheel 6. As the main reinforcing bar 4 enters the fourth driver 11, it passes between the first straightening roller 12 and the second straightening roller 13. The fourth driver 11 drives the straightening roller to rotate, applying pressure to the main reinforcing bar 4 and gradually straightening the bent main reinforcing bar 4. The straightened main reinforcing bar 4 then enters the second driver 5, where the feeding wheel... 6. Push the main reinforcement bar 4, which will be conveyed to the left along the longitudinal guide rail on the support 1. The leftmost side of the main reinforcement bar 4 is fixed on the first driver 2. Under the push of the second driver 5, the first driver 2 moves on the support 1. While the main reinforcement bar 4 is being fed, the third driver 7 starts to work. The stirrup plate is placed near the third driver 7. Six circumferentially distributed mechanical jaws 10 extend radially to grab the stirrups. The rotating disk 9 starts to rotate, which will drive the mechanical jaws 10 and the stirrups to make circumferential movements together. As the rotating disk 9 rotates, the stirrups are wrapped around the main reinforcement bar 4 that is being conveyed forward, thereby continuously making the steel cage.

[0050] When the size of the main rib 4 changes, the adjustment component 16, which is set in the inner wall of the fourth driver 11, is set between each set of straightening rollers. The cylinder 1607 pushes the second worm 1604 and the inner worm wheel 1605 outward, thereby reducing the gap between the first straightening roller 12 and the second straightening roller 13, and vice versa. At the same time, the locking tooth 3 and the feeding wheel 6 are driven by the first driver 2 and the second driver 5 respectively to adjust the engagement degree to adapt to the size of the main rib 4 being processed.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
