Description

Technical Field

[0001] This utility model relates to the technical field of precast bridge deck production, and in particular to a high-performance concrete bridge deck stacking device. Background Technology

[0002] Modern bridge engineering places higher demands on material performance, construction efficiency, and structural durability. Traditional cast-in-place concrete bridge decks, due to their long construction cycles, susceptibility to environmental disturbances (such as temperature and humidity fluctuations), and on-site operational errors, struggle to meet the long-term service requirements in complex environments. Precast assembly technology, through factory production, enables component standardization and quality control. The core advantages of precast technology lie in reducing on-site work and minimizing resource waste, while high-performance concrete bridge decks, by reducing cement usage (incorporating 30-50% industrial solid waste) and extending structural lifespan, further align with green construction principles. However, achieving efficient matching between multi-process workflows and precast technology remains a critical technical challenge that needs to be overcome.

[0003] Chinese Patent No. CN214610331U discloses a palletizing machine for prefabricated components, including a palletizing machine body, a fixed plate at the bottom of the palletizing machine body, a long groove at the bottom of the fixed plate, a square plate fixedly connected to the rear side of the fixed plate, a motor fixedly connected to the bottom of the square plate, a bidirectional screw fixedly connected to the output end of the motor, the front side of the bidirectional screw being movably connected to the front side of the inner wall of the long groove via a bearing, a gripper at the bottom of the fixed plate, a sliding groove at the bottom of the fixed plate, a slider fixedly connected to the top of the gripper for use with the sliding groove, a base plate at the bottom of the palletizing machine body, and a placement plate at the top of the base plate.

[0004] The existing technical solutions described above have the following drawbacks: After the concrete pouring system completes the concrete pouring inside the bridge deck mold, the workpiece conveyor will transport the concrete-filled bridge deck mold to the loading position of the palletizer. The palletizer starts running via a motor, which drives the grippers to move inward through a bidirectional screw to clamp the workpieces and complete the stacking of the workpieces on the placement plate. However, after a row of workpieces is stacked to a predetermined height, since the placement plate is fixed, a forklift needs to be manually driven under the palletizer body to transfer these workpieces. This not only increases labor costs but also reduces stacking efficiency. Furthermore, the limited space for the forklift to enter and exit poses certain safety risks, and the workpieces are prone to bumping into the palletizer body. Improvements are needed. Utility Model Content

[0005] The present invention aims to address the aforementioned shortcomings in the existing technology by providing a high-performance concrete bridge deck stacking device. This device utilizes a movable placement plate to facilitate the transfer of workpieces between the stacking position and the exit point, offering advantages such as easy forklift transfer of workpieces, prevention of workpiece collisions, and improved stacking efficiency.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: A high-performance concrete bridge deck stacking device, used in conjunction with a workpiece conveyor, includes a pair of symmetrically arranged first translation mechanisms, a placement plate disposed at the moving end of the first translation mechanisms, a frame spanning the workpiece conveyor and the pair of first translation mechanisms, a second translation mechanism disposed on the frame, a lifting drive mechanism disposed at the moving end of the second translation mechanism, and a gripper disposed at the moving end of the lifting drive mechanism. The movement path of the placement plate sequentially passes through the stacking position and the stacking outlet of the frame, and the movement path of the gripper sequentially passes through the discharge position of the workpiece conveyor and the placement plate located at the stacking position. The top surface of the placement plate is arranged opposite the bottom surface of the workpiece.

[0007] By adopting the above technical solution, after the concrete pouring system completes the concrete pouring inside the bridge deck mold, the workpiece conveyor transports the bridge deck mold containing concrete to the discharge position. First, the second translation mechanism drives the lifting drive mechanism and the gripper to move above the discharge position. The lifting drive mechanism then drives the gripper to descend, clamping the workpiece at the discharge position. Next, the lifting drive mechanism drives the gripper to rise, and the second translation mechanism moves the gripper and workpiece above the placement plate at the stacking position. The lifting drive mechanism then drives the gripper to descend again, placing the workpiece on the placement plate at the stacking position. Repeat the above steps. As a column of workpieces is stacked to a predetermined height, the first translation mechanism is activated. The first translation mechanism drives the placement plate to move from the stacking position to the exit port. At the exit port, the forklift can easily transfer the workpieces on the placement plate. Since the position of the placement plate is adjustable, it avoids the need for manual operation of the forklift under the frame, reducing labor costs and improving stacking efficiency. At the same time, the forklift operates at the exit port, with a larger operating space, reducing safety risks and preventing workpieces from bumping into the palletizer body, thus ensuring the normal operation of the device and the quality of the workpieces.

[0008] The present invention is further configured such that: the first translation mechanism includes a base, a first drive motor disposed on the base, a pair of first drive sprockets coaxially disposed on the output shaft of the first drive motor, a pair of first driven sprockets rotatably connected to the base, and a first transmission chain meshing with the first drive sprockets and the first driven sprockets; the placement plate is slidably connected to the base and disposed on the pair of first transmission chains.

[0009] By adopting the above technical solution, after the first drive motor starts, its output shaft drives the first drive sprocket to rotate. Since the first transmission chain is meshed and sleeved on the first drive sprocket and the first driven sprocket, the rotation of the first drive sprocket will drive the first transmission chain to move. The placement plate is slidably connected to the base and set on the pair of first transmission chains. The movement of the first transmission chain will drive the placement plate to slide on the base. This structural design allows the placement plate to move smoothly between the stacking position and the exit point under the drive of the first translation mechanism. Moreover, this chain drive method has the characteristics of high transmission efficiency and accurate transmission ratio, which can ensure the accuracy and stability of the placement plate movement. At the same time, the chain drive can adapt to certain load changes. Even if a large number of workpieces are stacked on the placement plate, it can reliably drive the placement plate to move, thereby ensuring the efficient operation of the entire stacking device.

[0010] The present invention is further configured such that: the first translation mechanism includes a guide bar disposed on the frame and a guide plate disposed at one end of the guide bar near the workpiece conveyor, the guide bar is arranged relative to the outer surface of the workpiece, and the length direction of the guide bar is parallel to the moving direction of the placement plate.

[0011] By adopting the above technical solution, the guide bar provides guidance for the workpieces on the placement plate, ensuring a relatively stable position for the workpieces during the plate's movement and preventing them from shifting or swaying. The guide plate, located at the end of the guide bar near the workpiece conveyor, guides the workpiece smoothly into the area defined by the guide bar when it is transferred from the conveyor to the placement plate, ensuring accurate placement and improving the placement accuracy. This makes the entire stacking process more precise and orderly. Furthermore, because the guide bar is positioned relative to the outer surface of the workpiece and its length is parallel to the direction of movement of the placement plate, it continuously constrains and guides the workpiece during the plate's movement, ensuring it remains in the correct position throughout the process. This facilitates subsequent palletizing operations and improves the overall performance and efficiency of the stacking device.

[0012] The present invention is further configured such that the end of the guide bar away from the workpiece conveyor is folded outward to form a gradually expanding first guide portion.

[0013] By adopting the above technical solution, it is easier to guide the forklift to unload the workpiece located at the stack exit.

[0014] The present invention is further configured such that the inner side of the guide plate is folded toward the workpiece conveyor and forms a tapered second guide portion.

[0015] By adopting the above technical solution, it is easier to guide the workpieces to be stacked at the stacking position.

[0016] The present invention is further configured such that the outer side of the placement plate is folded upward to form a flange.

[0017] By adopting the above technical solution, the workpiece can be limited on both sides, preventing it from easily detaching from the placement plate.

[0018] The present invention is further configured such that: the second translation mechanism includes a horizontal rack and at least two slide rails arranged side by side on the frame, a motor base slidably connected to these slide rails, a second drive motor arranged on the motor base, a second drive sprocket arranged on the output shaft of the second drive motor, a rotating shaft rotatably connected to the motor base, a second driven sprocket and a transmission gear arranged on the rotating shaft, and a second transmission chain meshing with the second drive sprocket and the second driven sprocket, the transmission gear meshing with the horizontal rack, and the lifting drive mechanism arranged on the motor base.

[0019] By adopting the above technical solution, the second drive motor drives the second driven sprocket to rotate through the second active sprocket and the second transmission chain, thereby causing the transmission gear on the rotating shaft to roll on the horizontal rack, realizing the translation of the motor base along the slide rail. This transmission method is efficient and the power transmission is stable, and it can accurately control the translation distance and speed. Since the lifting drive mechanism is set on the motor base, as the motor base translates, the lifting drive mechanism can also accurately move to the designated position, thereby driving the workpiece to make horizontal position adjustments to meet different stacking requirements.

[0020] The present invention is further configured such that: the lifting drive mechanism includes a third drive motor and a vertical slide mounted on the moving end of the second translation mechanism, a drive gear mounted on the output shaft of the third drive motor, a vertical rail slidably connected to the vertical slide, and a lifting rack mounted on the vertical rail, wherein the drive gear is meshed with the lifting rack, and the gripper is mounted on the bottom end of the vertical rail.

[0021] By adopting the above technical solution, the third drive motor drives the active gear to rotate. Since the active gear meshes with the lifting rack, the rotation of the active gear causes the vertical rail to move up and down along the vertical slide. This transmission method can convert the rotational motion of the third drive motor into the linear lifting motion of the vertical rail, which has high transmission efficiency and stability. Since the gripper is set at the bottom of the vertical rail, the gripper can also be adjusted vertically as the vertical rail moves up and down. In actual stacking operations, by precisely controlling the rotation direction and number of revolutions of the third drive motor, the lifting height of the gripper can be precisely controlled, thereby enabling the gripping and stacking of workpieces at different heights. This further improves the flexibility and applicability of the stacking device, better meets diverse stacking needs, and effectively improves the efficiency and quality of stacking work.

[0022] In summary, the beneficial technical effects of this utility model are as follows: the first translation mechanism drives the placement plate to move, completing the transfer of the workpiece between the stacking position and the exit port, and the second translation mechanism and the lifting drive mechanism drive the gripper to move, completing the transfer of the workpiece between the discharge position and the stacking position of the workpiece conveyor. It has the advantages of facilitating forklift transfer of workpieces, avoiding workpiece collisions, and improving stacking efficiency. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figure 1 This utility model discloses a high-performance concrete bridge deck stacking device for use in conjunction with a workpiece conveyor 7. It includes a pair of symmetrically arranged first translation mechanisms 1, a placement plate 2 located at the moving end of the first translation mechanism 1, a frame 3 spanning the workpiece conveyor 7 and the pair of first translation mechanisms 1, a second translation mechanism 4 mounted on the frame 3, a lifting drive mechanism 5 located at the moving end of the second translation mechanism 4, and a gripper 6 located at the moving end of the lifting drive mechanism 5. The movement path of the placement plate 2 sequentially passes through the stacking position and the stacking outlet of the frame 3, while the movement path of the gripper 6 sequentially passes through the discharge position of the workpiece conveyor 7 and the placement plate 2 located at the stacking position. The top surface of the placement plate 2 is arranged opposite the bottom surface of the workpiece.

[0029] After the concrete pouring system completes the concrete pouring in the bridge deck mold, the workpiece conveyor 7 transports the bridge deck mold with concrete to the discharge position. First, the second translation mechanism 4 drives the lifting drive mechanism 5 and the gripper 6 to move above the discharge position. The lifting drive mechanism 5 drives the gripper 6 to descend, and the gripper 6 clamps the workpiece located at the discharge position. Then, the lifting drive mechanism 5 drives the gripper 6 to rise, and the second translation mechanism 4 drives the gripper 6 and the workpiece to move above the placement plate 2 located at the stacking position. The lifting drive mechanism 5 then drives the gripper 6 to descend again, placing the workpiece on the placement plate 2 located at the stacking position. Repeat the above steps. As a row of workpieces is stacked to a predetermined height, the first translation mechanism 1 is activated. The first translation mechanism 1 drives the placement plate 2 from the stacking position to the exit port. At the exit port, the forklift can easily transfer the workpieces on the placement plate 2. Since the position of the placement plate 2 is adjustable, it avoids the need for manual operation of the forklift under the frame 3, reducing labor costs and improving stacking efficiency. At the same time, the forklift operates at the exit port, which provides a larger operating space, reducing safety risks and preventing workpieces from bumping into the palletizer body, thus ensuring the normal operation of the device and the quality of the workpieces.

[0030] Reference Figure 2The first translation mechanism 1 includes a base 11, a first drive motor 12 mounted on the base 11, a pair of first drive sprockets 13 coaxially mounted on the output shaft of the first drive motor 12, a pair of first driven sprockets 14 rotatably connected to the base 11, a first transmission chain 15 meshing with the first drive sprockets 13 and the first driven sprockets 14, a guide bar 16 mounted on the frame 3, and a guide plate 17 mounted on the end of the guide bar 16 near the workpiece conveyor 7. The placement plate 2 is slidably connected to the base 11 and mounted on the pair of first transmission chains 15. The guide bar 16 is arranged relative to the outer surface of the workpiece, and the length direction of the guide bar 16 is parallel to the moving direction of the placement plate 2. The end of the guide bar 16 away from the workpiece conveyor 7 is folded outward to form a gradually expanding first guide portion 161. The inner side of the guide plate 17 is folded towards the workpiece conveyor 7 to form a gradually contracting second guide portion 171. The outer side of the placement plate 2 is folded upward to form a flange 21.

[0031] After the first drive motor 12 starts, its output shaft drives the first drive sprocket 13 to rotate. Since the first transmission chain 15 is meshed on the first drive sprocket 13 and the first driven sprocket 14, the rotation of the first drive sprocket 13 will drive the first transmission chain 15 to move. The placement plate 2 is slidably connected to the base 11 and set on the pair of first transmission chains 15. The movement of the first transmission chain 15 will drive the placement plate 2 to slide on the base 11. This structural design allows the placement plate 2 to move smoothly between the stacking position and the exit point under the drive of the first translation mechanism 1. Moreover, this chain drive method has the characteristics of high transmission efficiency and accurate transmission ratio, which can ensure the accuracy and stability of the movement of the placement plate 2. At the same time, the chain drive can adapt to certain load changes. Even if a lot of workpieces are stacked on the placement plate 2, it can reliably drive the placement plate 2 to move, thereby ensuring the efficient operation of the entire stacking device.

[0032] The guide bar 16 provides guidance for the workpieces on the placement plate 2, ensuring a relatively stable position during the movement of the placement plate 2 and preventing workpiece displacement or swaying. The guide plate 17, located at the end of the guide bar 16 near the workpiece conveyor 7, guides the workpiece smoothly into the area defined by the guide bar 16 when it is transferred from the conveyor to the placement plate 2, ensuring accurate placement of the workpiece on the placement plate 2 and further improving the placement accuracy of the workpiece. This makes the entire stacking process more precise and orderly. Simultaneously, because the guide bar 16 is arranged relative to the outer surface of the workpiece and its length direction is parallel to the moving direction of the placement plate 2, it continuously constrains and guides the workpiece during the movement of the placement plate 2, ensuring that the workpiece remains in a suitable position throughout the movement. This facilitates subsequent stacking operations and improves the overall performance and efficiency of the stacking device.

[0033] Reference Figure 3 The second translation mechanism 4 includes a horizontal rack 41 and two slide rails 42 arranged side by side on the frame 3, a motor base 43 slidably connected to these slide rails 42, a second drive motor 44 mounted on the motor base 43, a second drive sprocket 45 mounted on the output shaft of the second drive motor 44, a rotating shaft 46 rotatably connected to the motor base 43, a second driven sprocket 47 and a transmission gear 48 mounted on the rotating shaft 46, and a second transmission chain 49 meshing with the second drive sprocket 45 and the second driven sprocket 47. The transmission gear 48 is meshed with the horizontal rack 41, and the lifting drive mechanism 5 is mounted on the motor base 43.

[0034] The second drive motor 44 drives the second driven sprocket 47 to rotate via the second active sprocket 45 and the second transmission chain 49, which in turn causes the transmission gear 48 on the rotating shaft 46 to roll on the horizontal rack 41, thereby enabling the motor base 43 to translate along the slide rail 42. This transmission method is efficient and provides stable power transmission, and can precisely control the translation distance and speed. Since the lifting drive mechanism 5 is set on the motor base 43, as the motor base 43 translates, the lifting drive mechanism 5 can also accurately move to the designated position, thereby driving the workpiece to make horizontal position adjustments to meet different stacking requirements.

[0035] The lifting drive mechanism 5 includes a third drive motor 51 and a vertical slide 52 mounted on a motor base 43, a drive gear 53 mounted on the output shaft of the third drive motor 51, a vertical rail 54 slidably connected to the vertical slide 52, and a lifting rack 55 mounted on the vertical rail 54. The drive gear 53 is meshed with the lifting rack 55, and the gripper 6 is located at the bottom end of the vertical rail 54.

[0036] The third drive motor 51 drives the drive gear 53 to rotate. Since the drive gear 53 meshes with the lifting rack 55, the rotation of the drive gear 53 causes the vertical rail 54 to move up and down along the vertical slide 52. This transmission method can convert the rotational motion of the third drive motor 51 into the linear lifting motion of the vertical rail 54, which has high transmission efficiency and stability. Since the gripper 6 is set at the bottom of the vertical rail 54, the gripper 6 can also be adjusted vertically as the vertical rail 54 rises and falls. In actual stacking operations, by precisely controlling the rotation direction and number of revolutions of the third drive motor 51, the lifting height of the gripper 6 can be precisely controlled, thereby enabling the gripping and stacking of workpieces at different heights. This further improves the flexibility and applicability of the stacking device, better meets diverse stacking needs, and effectively improves the efficiency and quality of stacking work.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
