Description

Technical Field

[0001] The present application relates to the technical field of precast concrete parts manufacturing, and in particular to a device for manufacturing precast concrete anti-falling beam blocking parts for bridges. Background Art

[0002] In bridge construction, concrete anti-falling beam barriers play a vital role in ensuring the stability of bridge structures under special working conditions such as earthquakes. The traditional manufacturing process of concrete anti-falling beam barriers often relies on relatively simple and inefficient manual operations. Workers need to manually carry the steel bars to the vicinity of the mold or casting box where part of the concrete has been poured, and then insert the steel bars into the concrete based on experience and manpower. When inserting the steel bars, it is difficult to ensure that the bending direction of multiple steel bars is uniform because there is a lack of special positioning and rotation adjustment devices. This easily leads to unstable mechanical properties of the anti-falling beam barriers in subsequent use, and the best anti-falling beam effect cannot be achieved. Moreover, after the steel bars are inserted into the concrete by manual operation, it is difficult to ensure that the steel bars always maintain a fixed position and angle during the concrete solidification process. Once the steel bars are displaced or the angle changes, it will seriously affect the quality and reliability of the barriers. In addition, the traditional manual operation method has high labor intensity and low production efficiency, and it is difficult to meet the large-scale, high-quality and high-efficiency production requirements of modern bridge construction. Therefore, there is an urgent need for a bridge precast concrete anti-fall beam barrier manufacturing equipment that can realize automation, precise positioning, rotation adjustment and fixation of steel bars to improve production efficiency and product quality and ensure the safety and stability of bridge structures.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0022] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

For example, the first groove and the second groove are only used to distinguish different grooves, and their order is not limited. Those skilled in the art can understand that the words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not necessarily limit them to be different.

[0024] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0025] refer to Figure 1-Figure 2 A bridge precast concrete anti-fall beam barrier manufacturing equipment, including: a casting box 10; a lifting mechanism 20, which is arranged outside the casting box 10; a rotating mechanism 30, which is connected to the lifting mechanism 20; a positioning mechanism 40, which is arranged on the rotating mechanism 30, and is used to fix and position the steel bars; a positioning sensor, which is used to identify the angle of the bent end of the steel bar and confirm that the steel bar is in place; the lifting mechanism 20 is used to move the positioning mechanism 40 above the casting box 10, and the positioning mechanism 40 is moved to the top of the casting box 10 by the rotating mechanism 30, so as to insert the steel bars into the casting box 10 and keep them fixed.

[0026] Each mechanism of the equipment is in the initial position, and the steel bars to be inserted into the concrete are placed on the positioning mechanism 40. The positioning mechanism 40 performs preliminary fixation on the steel bars to ensure that the steel bars will not be greatly displaced or disordered in subsequent operations. Start the lifting mechanism 20, and the lifting motor works to drive the lifting slider 202 to move upward along the lifting track 201, thereby lifting the rotating mechanism 30 connected to the lifting slider 202 and the positioning mechanism 40 with the steel bars fixed thereon to a certain height, so that they can be smoothly moved to the working area above the casting box 10. After being lifted to a suitable height, the rotating motor 301 is started to drive the rotating platform 302 to rotate, and the rotating platform 302 drives the positioning mechanism 40 to rotate precisely in the horizontal direction, adjusting the steel bars to the predetermined angle position directly above the casting box 10, so that the insertion direction of the steel bars matches the design requirements, and ensures that the bending directions of multiple steel bars are consistent when inserted into the concrete.

[0027] After the rotational positioning is completed, the lifting mechanism 20 is activated again to slowly lower the positioning mechanism 40 and the steel bars and insert them into the pre-poured concrete in the casting box 10. During the insertion process, the positioning mechanism 40 always maintains a fixed effect on the steel bars to prevent the steel bars from shifting or shaking, ensuring that the steel bars can be accurately inserted into the predetermined depth and position in the concrete, and maintain a stable posture until the concrete solidifies, finally forming a concrete anti-fall beam barrier main structure that meets the requirements. After the steel bars are inserted into the concrete in the casting box 10, the positioning sensor is activated again to accurately measure the actual angle of the bent end of the steel bar that has been inserted into the concrete, and transmit the measured data to the control system of the equipment. The control system compares and analyzes the received actual angle data with the preset standard angle value, and calculates the deviation between the two.

[0028] If there is an angle deviation, the control system generates a corresponding rotation control instruction based on the deviation information and transmits it to the rotating motor 301 in the positioning mechanism 40. The rotating motor 301 drives the rotating platform 302 to rotate according to the instruction, thereby driving the steel bar to rotate. During the rotation process, the positioning sensor continuously monitors the angle change of the steel bar and feeds back to the control system in real time. The control system continuously adjusts the operation of the rotating motor 301 according to the feedback until the angle of the bent end of the steel bar is completely consistent with the preset standard angle value, ensuring that the angle of the steel bar in the concrete meets the design requirements of the precast concrete anti-fall beam blocking member of the bridge.

[0029] During the entire process, the positioning mechanism 40 always plays the role of fixing and positioning the steel bars, ensuring that the steel bars can maintain a stable position and posture during a series of operations such as lifting, rotating, inserting into concrete and adjusting the angle until the concrete solidifies, finally forming a main structure of the anti-falling beam barrier that meets the requirements.

[0030] In this embodiment, the diameter of the positioning hole 402 is larger than the steel bar.

[0031] The positioning sensor can be a laser distance sensor, which uses laser triangulation to emit a laser beam to the bent end surface of the steel bar and then receive the reflected light. When the angle of the steel bar changes, the position of the reflected light will also change accordingly. According to the change in the position of the reflected light on the sensor receiving element, the angle change of the steel bar can be calculated using the trigonometric function relationship. Alternatively, an inclination sensor can be used.

[0032] In some embodiments, a vibration motor is disposed on the outer wall of the casting box 10 to compact the pre-cast concrete base in the casting box 10 .

[0033] Effectively improve the density of the concrete base, reduce internal voids and bubbles, enhance the strength and durability of concrete, enable the anti-falling beam blocker to better withstand various loads, improve its stability and reliability in the bridge structure, extend its service life, and reduce the risk of structural failure caused by concrete quality problems. Improve the bonding performance between concrete and steel bars, so that the two work together better, better transfer stress, and improve the overall mechanical properties of the anti-falling beam blocker.

[0034] After pouring the concrete base into the pouring box 10, the vibration motor is turned on. The vibration motor generates high-frequency vibration, which is transmitted to the concrete through the pouring box 10. Under the action of vibration, the particles inside the concrete are subjected to periodic forces, and the loosely stacked particles begin to rearrange and fill the gaps. Small particles gradually fill the gaps between large particles, and air bubbles are also discharged, so that the concrete gradually becomes dense, forming a more solid concrete base, laying a good foundation for the subsequent insertion of steel bars and the overall structural performance.

[0035] The lifting mechanism 20 includes a lifting rail 201 , a lifting motor and a lifting slider 202 . The lifting slider 202 is slidably connected to the lifting rail 201 , and the lifting motor drives the lifting slider 202 .

[0036] The vertical movement of the positioning mechanism 40 can be precisely controlled to achieve smooth lifting and lowering of the positioning mechanism 40, ensuring that the steel bars can be accurately inserted into the predetermined positions in the concrete under different height requirements, thereby improving the accuracy and reliability of equipment operation.

[0037] The lifting mechanism 20 operates smoothly and efficiently, and the height of the positioning mechanism 40 can be quickly adjusted according to the production rhythm, which helps to improve the production efficiency of the entire manufacturing equipment and adapt to different process requirements and production scales.

[0038] After receiving the control signal, the motor starts, and its output shaft rotates to drive the transmission components (such as gears, screws, etc., depending on the specific design) connected thereto to operate, so that the lifting slider 202 performs linear sliding motion along the lifting track 201. By controlling the parameters such as the forward and reverse rotation, speed, and operation time of the lifting motor, the height and speed of the lifting slider 202 can be accurately controlled to rise or fall, thereby driving the rotating mechanism 30 and the positioning mechanism 40 connected thereto to achieve precise vertical movement, and transport the steel bar to a suitable height position for subsequent rotation and insertion operations.

[0039] The rotating mechanism 30 includes a rotating platform 302 and a rotating motor 301 . The rotating motor 301 is connected to the lifting mechanism 20 , and a driving end of the rotating motor 301 is drivingly connected to the rotating platform 302 .

[0040] The positioning mechanism 40 and the angle of the steel bar can be flexibly adjusted in the horizontal plane to ensure the consistency and accuracy of the bending direction of multiple steel bars when inserted into concrete, meet the strict requirements of the anti-falling beam blocking piece on the specific angle of the steel bar layout, and improve the stability and standardization of product quality.

[0041] The rotating mechanism 30 can quickly respond to control instructions, achieve accurate angle positioning, reduce adjustment time, and improve production efficiency. In addition, the rotation process is smooth and will not cause adverse effects on the positioning of the steel bars and the overall structure of the equipment.

[0042] After the lifting mechanism 20 lifts the rotating mechanism 30 and the positioning mechanism 40 to a suitable height above the casting box 10, the control system sends a rotation angle instruction to the rotating motor 301. The rotating motor 301 drives the rotating platform 302 to rotate around its central axis according to the instruction. The rotating platform 302 is rigidly connected to the positioning mechanism 40, so the positioning mechanism 40 will rotate synchronously with the rotating platform 302. Through the precise control of the motor, such as using an encoder to feedback the rotation angle information of the motor, the closed-loop control of the rotation angle is realized, so that the positioning mechanism 40 can accurately rotate to the predetermined angle position, adjust the steel bar to the correct insertion direction, and ensure that the structural performance of the anti-falling beam blocking member meets the design requirements.

[0043] In some embodiments, the positioning mechanism 40 includes: A positioning plate 401 having a plurality of regularly arranged positioning holes 402, wherein the diameter of the positioning holes 402 is larger than the diameter of the steel bars, and the steel bars are passed through the positioning holes 402; The winding mechanism 50 is arranged above the positioning hole 402; A lifting mechanism 60, connected to the winding mechanism 50, for lifting and lowering the winding mechanism 50; The moving mechanism 70 is arranged on the positioning plate 401; The driving belt 80, the rotating wheel 81 and the belt driving motor 82, the rotating wheel 81 is connected to the moving mechanism 70, the moving mechanism 70 drives the rotating wheel 81 to move along the radial direction of the positioning hole 402, the belt driving motor 82 is connected to the winding mechanism 50, the driving belt 80 forms a trasmittable arrangement with the driving shaft of the belt driving motor 82 as the first fulcrum, the steel bar as the second fulcrum, and the rotating wheel 81 as the third fulcrum, and the belt driving motor 82 is driven to move the driving belt 80 and rotate the steel bar after being inserted into the concrete; The belt fixing mechanisms 83 are respectively provided on the winding mechanism 50 and the moving mechanism 70, and can abut against the driving belt 80 so that the driving belt 80 is fixed at respective positions.

[0044] The steel bar first passes through the positioning hole 402 of the positioning plate 401, and the positioning hole 402 plays a preliminary limiting and positioning role for the steel bar to prevent it from being greatly offset in the horizontal direction. After being inserted into the concrete, when the angle of the steel bar needs to be adjusted, the belt drive motor 82 is started to drive the drive belt 80 to move. Since the drive belt 80 forms a transmittable arrangement with the drive shaft of the belt drive motor 82 as the first fulcrum, the steel bar as the second fulcrum, and the rotating wheel 81 as the third fulcrum, when the drive belt 80 moves, it will generate a torque around its own axis on the steel bar, causing the steel bar to rotate. After the steel bar is inserted, the winding mechanism 50, the lifting mechanism 60, the moving mechanism 70 and the belt fixing mechanism 83 cooperate with each other to tightly fix the steel bar in the concrete by winding the drive belt 80, etc., to ensure that its position and angle remain unchanged during the concrete solidification process.

[0045] The lifting mechanism 60 includes a lifting platform 601 .

[0046] The winding mechanism 50 is provided with stable vertical movement support, so that it can flexibly adjust the height position according to the insertion depth and fixing requirements of the steel bars, ensuring that the winding operation is carried out at a suitable height, and effectively improving the fixing effect of the steel bars and the convenience of equipment operation.

[0047] The lifting platform 601 operates smoothly and can accurately control the lifting height of the winding mechanism 50, ensuring that the winding mechanism 50 and the steel bars maintain a good relative position relationship under different working conditions, which is conducive to achieving tight winding and fixation of the steel bars and improving the structural reliability of the anti-falling beam barrier.

[0048] The lifting platform 601 is driven by a corresponding driving device (such as a hydraulic system, a motor screw transmission, etc.). When the height of the winding mechanism 50 needs to be adjusted, the control system sends a command to the driving device, and the driving device works to make the lifting platform 601 rise or fall. For example, in a hydraulic system, by controlling the hydraulic pump to supply or return oil to the hydraulic cylinder, the telescopic length of the hydraulic cylinder piston rod is changed, thereby driving the lifting platform 601 to move. In the motor screw transmission, the rotation of the motor drives the screw to rotate, so that the nut matched with the screw (the lifting platform 601 is connected to the nut) moves along the axial direction of the screw, realizing the vertical lifting movement of the lifting platform 601, and adjusting the winding mechanism 50 to a suitable height for winding and fixing the steel bars.

[0049] The winding mechanism 50 includes a circular ring 501 and a winding motor 502. The lifting platform 601 includes two and is symmetrically arranged relative to the positioning hole 402. The lifting platform 601 is provided with a recess 602 with the same curvature as that of the circular ring 501, so that the opposite ends of the circular ring 501 are just engaged in the recess 602. The winding motor 502 is connected to the lifting platform 601. The winding motor 502 is connected to the end face of the circular ring 501 through a gear drive. The belt drive motor 82 and one of the belt fixing mechanisms 83 are connected to the inner ring wall of the circular ring 501.

[0050] After the steel bar is inserted into the concrete, the lifting platform 601 rises to a predetermined height so that the opposite ends of the ring 501 fit into the notch 602 to ensure that the position of the ring 501 is stable. The winding motor 502 is started and drives the ring 501 to rotate through gear transmission. The belt drive motor 82 and one of the belt fixing mechanisms 83 are connected to the inner wall of the ring 501. During the rotation of the ring 501, the drive belt 80 is gradually wound around the steel bar under the coordinated action of other components. The speed and direction of rotation of the winding motor 502 are precisely controlled by the control system, and are adjusted according to parameters such as the diameter of the steel bar and the required number of windings to achieve precise control of the winding of the drive belt 80.

[0051] The moving mechanism 70 includes a moving track 701 and a moving platform. The moving platform can move on the moving track 701 through a built-in motor. When the driving belt 80 is driven to transmit, the moving platform is located at an end away from the positioning hole 402 .

[0052] The belt fixing mechanism 83 includes a belt fixing motor 831 and a fixing rubber block. The belt fixing motor 831 can drive the fixing rubber block to hold the driving belt 80 to fix the driving belt 80 .

[0053] After the driving belt 80 is fixed, the movable platform is driven to move toward the positioning hole 402, and at the same time, the lifting platform 601 is driven to rise and the winding motor 502 is controlled to drive the ring 501 to rotate, so that the driving belt 80 is wound around the steel bar to fix the steel bar after being inserted into the concrete in the casting box 10.

[0054] After or before the steel bar is rotated, when the steel bar needs to be fixed, the driving belt 80 is first fixed at the current position by the belt fixing mechanism 83 to prevent it from loosening. Then the moving platform is driven to move toward the positioning hole 402. This action causes the driving belt 80 to relax a certain length, and the winding motor 502 drives the ring 501 to rotate, and the steel bar begins to wrap around the driving belt 80. At the same time, the lifting platform 601 is lifted, driving the winding mechanism 50 to rise, providing a spiral binding method for the winding of the driving belt 80. For the driving belt 80, multiple limiting shafts and limiting sleeves are also provided. The driving belt 80 can adopt a rope structure to deal with the problem of its falling off and not easy to flip.

[0055] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
