Description

Technical Field

[0001] This utility model belongs to the field of highway bridge construction. More specifically, this utility model relates to a steel bar block anti-sway limiting device for automated production lines. Background Technology

[0002] In the engineering field, reinforced concrete structures such as box girders and bridge towers are quite complex. Currently, automated production lines are increasingly widely used in the flexible processing and forming of various steel reinforcement blocks. Taking precast box girder structures as an example, due to their long spans, the corresponding steel reinforcement block structures are also long. When mechanically forming continuous structural blocks, the flexibility of the steel reinforcement blocks during traction and movement on the production line increases with their forming length. If limiting and shaping devices are not installed on both sides of the block during the traction and forming process, the block will exhibit varying degrees of random left-right swaying as its length increases. This affects the manufacturing quality of the steel reinforcement blocks, causing deformation in the subsequent bending and forming of the stirrups, ultimately resulting in unevenness of the stirrup sides between layers, affecting the overall dimensional appearance of the steel reinforcement blocks. Furthermore, the final process in the steel reinforcement block manufacturing is automatic laser spot welding of the stirrups. Due to the left-right swaying of the blocks, the laser may not be able to accurately locate the weld seam, further affecting the overall welding quality of the stirrup lap welds. Ultimately, this leads to substandard quality in the automated forming of the steel reinforcement blocks. Utility Model Content

[0003] The purpose of this invention is to provide a sway-prevention and limiting device for steel bar blocks used in automated production lines, which effectively ensures the quality of steel bar block manufacturing, facilitates the identification of weld points in the closed lap weld of the block stirrups, and effectively ensures the smooth processing of steel bar blocks on automated production lines.

[0004] The technical solution adopted by this utility model to solve this technical problem is: a steel bar block anti-sway limiting device for automated production line, including: a fixed support, a lifting cylinder device, a limiting baffle and a control system;

[0005] The lifting cylinder device is installed on the base of the existing production line and drives the fixed support to move up and down.

[0006] Two sets of limiting baffles are respectively installed on the fixed support through a ball screw transmission mechanism, and the limiting baffles are configured such that their working surfaces face the side wall of the steel block;

[0007] The control system connects to and controls the lifting cylinder device.

[0008] As a further embodiment of this utility model, the ball screw transmission mechanism includes: a ball screw and a ball nut assembly; a limiting baffle is fixed to the ball nut assembly;

[0009] The end of the ball screw is fixedly supported on a fixed support by a bearing and a bearing housing, and the head of the ball screw is connected to the servo motor assembly by a coupling.

[0010] A further embodiment of this utility model is: it also includes a horizontal guide mechanism, which includes a slide rail arranged parallel to the ball screw and a slider connected to the bottom of the limiting baffle, so that the limiting baffle moves along the slide rail.

[0011] As a further aspect of this invention, the control system is connected to and controls the servo motor assembly.

[0012] A further embodiment of this utility model is: it also includes a lifting guide rod and a limiting sleeve, wherein the lifting guide rod is fixed on the base of the production line, the limiting sleeve is sleeved on the lifting guide rod, and the limiting sleeve is fixed to the fixed support.

[0013] As a further embodiment of this utility model, the limiting baffle is provided with an arc-shaped chamfer structure on both sides.

[0014] As a further embodiment of this utility model, the limiting baffle is provided with a support base, and the slider is fixed to the bottom of the support base.

[0015] As a further embodiment of this utility model, a row of freely rotating miniature rollers is embedded in the working surface of the limiting baffle.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. Highly efficient sway suppression and improved forming accuracy. Two sets of limit stops that can move in opposite directions precisely match the dimensions of steel bars of different widths. During the traction process, the stops rigidly limit the movement on both sides, completely resolving the dimensional deviation problem caused by the flexible swaying of long steel bars. Combined with the vertical avoidance function of the lifting cylinder device, it ensures that the device automatically descends in the non-working state to avoid interference with the traction mechanism; in the working state, it quickly rises and positions itself, achieving "zero-collision" intervention and ensuring continuous production line efficiency.

[0018] 2. The entire device boasts strong structural stability. The synergistic effect of the ball screw drive mechanism and the horizontal guide mechanism ensures the smooth movement of the limit baffle along the slide rail, eliminating the risk of movement jamming. By converting the sliding friction between the limit baffle and the reinforcing steel block into rolling friction, resistance is significantly reduced, wear on the limit baffle is greatly minimized, and the lifespan of critical components is extended.

[0019] 3. The curved chamfered edge of the baffle prevents the stirrups from rubbing against it, thus preventing steel bar deformation or damage to the limiting baffle due to structural interference.

[0020] 4. The lifting guide rod and the limit sleeve provide dual guidance for vertical movement, preventing cylinder eccentricity failure.

[0021] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0027] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific implementation process is as follows:

[0029] like Figures 1-3 As shown, this utility model provides a steel bar block anti-sway limiting device for automated production lines, including: a fixed support 3, a lifting cylinder device 2, a limiting baffle 5, and a control system;

[0030] The lifting cylinder device 2 is installed on the base of the existing production line and drives the fixed support 3 to move up and down; the piston rod end of the lifting cylinder device 2 is connected to the fixed support 3.

[0031] Two sets of limiting baffles 5 are respectively installed on the fixed support 3 through the ball screw 4 transmission mechanism, so that the distance between the two sets of limiting baffles 5 can be adjusted through the ball screw 4 transmission mechanism. The limiting baffles 5 are configured such that their working surfaces face the side wall of the steel block.

[0032] The control system connects to and controls the lifting cylinder device 2.

[0033] In the above technical solution, the fixed support 3 is a U-shaped steel structure base, which is mainly used to fix and support the ball screw 4 transmission mechanism and the limiting baffle 5. The two sets of independent limiting baffles 5 can be controlled synchronously according to the width of the steel bar block to realize the positioning of the limiting baffles 5 and limit the position of the steel bar block on the left and right sides.

[0034] This technical solution may also include the following technical details to better achieve the technical effect: each set of limiting baffles 5 is controlled by a set of ball screw transmission mechanisms, the ball screw transmission mechanism includes: ball screw 4 and ball nut pair; the limiting baffle 5 is fixed to the ball nut pair, and in this embodiment, the axes of the two sets of ball screws 4 are located on the same straight line;

[0035] The end of the ball screw 4 is fixedly supported on the fixed support 3 by bearings and bearing housing 7, and the head of the ball screw 4 is connected to the servo motor group 6 by a coupling. Under the drive of the servo motor group 6, the rotation of the screw is controlled, which drives the limit baffle 5 to move back and forth along the ball screw transmission mechanism.

[0036] This technical solution may also include the following technical details to better achieve the technical effect: it also includes a horizontal guide mechanism, which includes a slide rail 8 arranged parallel to the ball screw 4 and a slider connected to the bottom of the limiting baffle 5, so that the limiting baffle 5 can move along the slide rail 8. The slide rail 8 is arranged side by side with the ball screw 4 and is mainly used to provide support and sliding guidance for the limiting baffle 5 when it reciprocates under the action of the ball screw 4.

[0037] This technical solution may also include the following technical details to better achieve the technical effect: the control system connects to and controls the servo motor group 6, and drives the limiting baffles 5 to move in opposite directions or away from each other according to the width of the steel block, so as to adjust the distance between the two limiting baffles 5.

[0038] This technical solution may also include the following technical details to better achieve the technical effect: it also includes a lifting guide rod 9 and a limiting sleeve 1. The lifting guide rod 9 is fixed on the base of the production line, and the limiting sleeve 1 is sleeved on the lifting guide rod 9. The limiting sleeve 1 is fixed to the fixed support 3 and is used to provide guidance for the movement of the fixed support 3 when the lifting cylinder device 2 drives the fixed support 3 to move up and down.

[0039] This technical solution may also include the following technical details to better achieve the technical effect: the limiting baffle 5 is made of stainless steel of a certain thickness, and the two sides of the baffle are set with an arc-shaped chamfer structure to avoid the block stirrups from scraping and interfering with the limiting baffle 5 when entering and exiting, so as to avoid damage to the baffle.

[0040] This technical solution may also include the following technical details to better achieve the technical effect: the limiting baffle 5 is provided with a support base 10, and the slider is fixed to the bottom of the support base 10 and connected to the slide rail 8. The function of the support base 10 is, on the one hand, to increase the strength of the limiting baffle 5, and on the other hand, to form an integral part with the limiting baffle 5. Under the rotation of the ball screw 4, the limiting baffle 5 reciprocates along the slide rail 8 through the transmission action of the ball screw 4.

[0041] This technical solution may also include the following technical details to better achieve the technical effect: a row of freely rotating micro rollers are embedded in the working surface of the limiting baffle 5, and the outermost edge of all the micro rollers is on the same plane as the working surface of the limiting baffle 5, thereby changing sliding friction into rolling friction and greatly reducing frictional resistance and wear.

[0042] Working process of the anti-sway limit device for steel bar blocks in automated production lines:

[0043] 1. Initial avoidance stage: In the initial stage of steel block production, the control system starts the lifting cylinder device 2, which drives the fixed support 3 to descend to the low position along the lifting guide rod 1.

[0044] The synchronous control servo motor group 6 drives the limit baffles 5 on both sides to move outward along the ball screw 4 to the maximum distance; the whole device avoids the production line space and prevents collision with the traction mechanism.

[0045] 2. Lifting and positioning stage: When the steel bar block is pulled to the designated position above the device, the fixed support 3 of the lifting cylinder device 2 is controlled to rise along the lifting guide rod 9 to the working height, so that the limit baffle 5 is aligned with the side wall of the steel bar block.

[0046] 3. Width adaptive adjustment stage: According to the preset width of the steel block, the servo motor group 6 drives the ball screw 4 to rotate; the limit baffle 5 moves precisely to the opposite sides of the steel block through the guidance of the ball nut pair and the slide rail 8.

[0047] 4. Dynamic limiting and anti-swaying stage: As the steel bar block continues to be pulled and extended, if there is a tendency to swing left and right, the side wall of the block will contact the limiting baffle 5, which will generate a certain resistance to prevent the steel bar block from swinging left and right, thereby limiting the horizontal movement of the steel bar block along the pulling direction to ensure the overall dimensions of the steel bar block.

[0048] 5. Reset and Unloading Stage: After the steel block is manufactured, the drive servo motor group 6 moves the limit baffle 5 to both sides through the transmission of the ball screw 4, opens the limit baffle, and smoothly lifts the block off the production line.

[0049] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
