Description

Technical Field

[0001] This utility model relates to the technical field of bridge precast component production, and in particular to a multi-station continuous concrete placing device. Background Technology

[0002] With the rapid development of highway construction technology, high-quality, efficient, and safe construction has become a new direction for bridge engineering. Bridges are projects of paramount importance, and construction quality is crucial. Precast concrete components are essential parts of prefabricated bridge structures. They are prefabricated in factories and then assembled on-site. Factory production standards are uniform, resulting in high quality, and the production environment is superior, with less dust pollution. The rise of prefabricated construction and the emergence of precast concrete components have greatly improved building quality and shortened bridge construction time. The production of bridge precast concrete components involves placing concrete material in molds and then curing it. The production process requires placing concrete material into the molds.

[0003] Chinese Patent CN215882038U discloses an automated circular production line for the prefabrication of high-speed railway bridge components. The production line includes a conveyor track, with a series of stations arranged along the conveying direction: a demolding station, a mold cleaning station, a release agent spraying station, a steel mesh and embedded part installation and inspection station, a mold closing station, a concrete placement and vibration station, and an initial finishing station. The concrete placement and vibration station is equipped with a spreading and placing device, which includes: a frame with a first track parallel to the conveying direction of the conveyor track; a first support slidably mounted on the frame along the first track, with a second track perpendicular to the first track; a second support slidably mounted on the first support along the second track; and a concrete placing machine mounted on the second support via an electric hoist.

[0004] The existing technical solutions described above have the following drawbacks: The above-mentioned paving and placing device mainly relies on the coordinated action of the first and second tracks to achieve two-dimensional movement of the placing machine in the horizontal direction. This design shows significant efficiency in most cases. However, the situation is different when it comes to the casting of large bridge precast components. Given the huge demand for concrete from large components, a single placing operation often cannot fully meet the demand. Therefore, the placing machine must perform multiple loading and unloading operations to ensure a continuous supply of concrete. This repetitive operation is not only time-consuming but also inefficient and needs to be improved. Utility Model Content

[0005] The present invention aims to address the aforementioned shortcomings in the existing technology by providing a multi-station continuous concrete placing device, which has the advantage of improving concrete pouring efficiency.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0007] A multi-station continuous concrete placing device is used to coordinate with the mold arrangement on the conveying track. It includes a pair of X-axis drive assemblies, a pair of Z-axis drive assemblies, and two pairs of placing machines. The pair of X-axis drive assemblies are arranged parallel to the conveying track. The pair of Z-axis drive assemblies are respectively located at the moving ends of the pair of X-axis drive assemblies and span over the conveying track. The two pairs of placing machines are respectively located at the moving ends of the pair of Z-axis drive assemblies, and their moving paths pass sequentially over the mold.

[0008] By adopting the above technical solution, each of the X-axis drive components independently drives the Z-axis drive components to feed along the X-axis direction, that is, to move horizontally along the direction parallel to the conveying track. This allows the concrete placing boom to pour concrete at different positions along the length of the mold, achieving precise placement of the concrete on the mold and meeting the requirements for concrete uniformity in large bridge precast components. Simultaneously, each of the Z-axis drive components independently drives the two pairs of concrete placing booms to move along the Z-axis direction, that is, to move horizontally along the direction perpendicular to the conveying track. This allows, in a single placement operation, while one of the placing booms is placing concrete, the other is discharging through the concrete mixer truck or the mixing plant outlet. This system loads or waits for concrete to be loaded, reducing the number of loading and unloading operations of the concrete placing boom, improving placing efficiency, and enabling continuous placing operations. During this process, the X-axis drive assembly drives the placing boom to place concrete at fixed points, achieving uniform placement of concrete within the mold. A Z-axis drive assembly further drives two placing booms to alternate placing operations, further improving overall work efficiency and avoiding the problems of concrete accumulation or missing concrete that may occur in traditional placing methods. This improves the quality of precast bridge components. Furthermore, the device has advantages such as simple structure, convenient operation, and low maintenance costs, making it suitable for the production of precast bridge components of various scales and possessing broad market application prospects.

[0009] The present invention is further configured such that: the X-axis drive assembly includes a vertical truss, an X-axis linear module disposed on the vertical truss, and a horizontal truss, the horizontal truss being disposed at the moving end of the X-axis linear module, and the Z-axis drive assembly being disposed on the horizontal truss.

[0010] By adopting the above technical solution, the vertical truss serves as the main supporting structure, ensuring the overall stability of the X-axis drive assembly. The X-axis linear module provides the horizontal truss with precise X-axis movement capability, enabling the Z-axis drive assembly and the placing machine to be accurately positioned along the length of the mold. The horizontal truss effectively connects the vertical truss and the Z-axis drive assembly, playing a crucial connecting role and ensuring the transmission of force and the smoothness of movement. This design not only improves the stability of the device but also guarantees the accuracy and efficiency of the placing operation.

[0011] The present invention is further configured such that: the X-axis drive assembly further includes an X-direction slide rail disposed on the vertical truss; the pair of X-axis drive assemblies are respectively arranged on both sides of the conveying track; and the horizontal truss is slidably connected to the X-direction slide rail of the other X-axis drive assembly.

[0012] By adopting the above technical solution, a pair of X-axis drive components are respectively set on both sides of the conveying track, and the horizontal truss of one X-axis drive component is slidably connected to the X-axis slide rail of the other X-axis drive component. This design creates a mutually supporting and guiding structure between the two X-axis drive components, further enhancing the stability and load-bearing capacity of the entire device. During the concrete placement operation, even when facing a large amount of concrete required for large bridge precast components, the device can maintain a stable working state, ensuring the smooth progress of the concrete placement operation. At the same time, this design also facilitates the maintenance and adjustment of the device, improving its flexibility and applicability.

[0013] The present invention is further configured such that: the Z-axis drive assembly includes a Z-axis linear module and a Z-axis slide rail disposed at the moving end of the X-axis drive assembly, and an I-beam bracket; the Z-axis linear module and the Z-axis slide rail are disposed above the conveying track in a manner perpendicular to the conveying track; the I-beam bracket is disposed at the moving end of the Z-axis linear module and slidably connected to the Z-axis slide rail; wherein two fabric placing machines in a pair are arranged alternately on the I-beam bracket.

[0014] By adopting the above technical solution, the Z-axis linear module provides the I-beam support with precise Z-axis movement capability, enabling the material placing machine to perform material placing operations in a direction perpendicular to the conveyor track. The I-beam support effectively connects the Z-axis linear module and the material placing machine, playing a supporting and guiding role, and ensuring the smooth movement of the material placing machine in the vertical direction.

[0015] The present invention is further configured such that: the fabric feeding machine includes a frame, a fabric hopper disposed on the frame, a vibrating motor disposed on the fabric hopper, a pair of discharge baffles hinged to the fabric hopper, and a switch driving assembly disposed on the pair of discharge baffles, wherein the pair of discharge baffles are driven to rotate by the switch driving assembly to selectively block the discharge port of the fabric hopper.

[0016] By adopting the above technical solution, the concrete hopper is used to hold concrete materials. The vibrating motor generates vibration, which allows the concrete materials in the hopper to fall evenly, preventing the concrete from accumulating or solidifying in the hopper, thereby improving the uniformity and efficiency of the concrete distribution. A pair of discharge baffles are flipped by a switch drive component to selectively block the discharge port of the concrete hopper. This design can adjust the opening degree of the discharge port according to actual needs, thereby controlling the concrete flow rate and distribution speed, further improving the accuracy and flexibility of the concrete distribution.

[0017] The present invention is further configured such that: a pair of vibration motors are provided and symmetrically arranged on both sides of the fabric hopper.

[0018] By adopting the above technical solution, it can be ensured that the concrete material in the hopper is subjected to uniform vibration, thereby further improving the uniformity and efficiency of the concrete placement. At the same time, this symmetrical arrangement can also enhance the stability of the hopper, avoid shaking or tilting during the placement process, and ensure the stability and reliability of the concrete placement operation.

[0019] The present invention is further configured such that the surface of the discharge baffle is provided with a magnetic coating.

[0020] By adopting the above technical solution, the magnetic coating can make the discharge baffle fit more firmly when blocking the discharge port of the hopper, avoiding the situation where concrete material slips or drips on the discharge baffle, thereby reducing concrete waste and improving the accuracy and efficiency of material placement.

[0021] The present invention is further configured such that: the switch drive assembly includes transmission gears respectively disposed on the pair of discharge baffles and meshing with each other, a connecting rod hinged to the discharge baffles, and a drive cylinder hinged to one of the connecting rods and the piston rod hinged to the other connecting rod.

[0022] By adopting the above technical solution, when the piston rod of the drive cylinder extends or retracts, it can drive the two connecting rods to swing. Since the two connecting rods are meshed through transmission gears, they will swing synchronously and in opposite directions, thereby driving the discharge baffle to flip synchronously and in opposite directions, realizing the opening and closing operation of the discharge port of the concrete hopper. This design is not only simple in structure and easy to implement, but also has high transmission efficiency and fast response speed, which can ensure the stability and reliability of the concrete placing machine during the material placing process. At the same time, by adjusting the extension and retraction of the drive cylinder, the flipping angle of the discharge baffle can be precisely controlled, thereby achieving precise adjustment of concrete flow rate and material placing speed.

[0023] In summary, the beneficial technical effects of this utility model are as follows: by driving the placing boom to place concrete at fixed points using the X-axis drive assembly, uniform concrete placement within the mold is achieved. Furthermore, the Z-axis drive assembly drives two placing booms to alternately perform placement operations, further improving overall work efficiency and avoiding the problems of concrete accumulation or missing concrete that may occur in traditional placement methods. This improves the quality of precast bridge components. In addition, the device has advantages such as simple structure, convenient operation, and low maintenance costs, making it suitable for the production of precast bridge components of various scales and possessing broad market application prospects.

[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 1This utility model discloses a multi-station continuous concrete placing device for use in conjunction with mold arrangement on a conveying track. It includes a pair of X-axis drive assemblies 1, a pair of Z-axis drive assemblies 2, and two pairs of placing booms 3. The pair of X-axis drive assemblies 1 are arranged parallel to the conveying track and respectively on both sides of the track. The pair of Z-axis drive assemblies 2 are respectively located at the moving ends of the pair of X-axis drive assemblies 1 and span over the conveying track. The two pairs of placing booms 3 are respectively located at the moving ends of the pair of Z-axis drive assemblies 2, and their movement paths sequentially pass over the molds.

[0029] Each pair of X-axis drive components 1 independently drives the pair of Z-axis drive components 2 to feed along the X-axis direction, that is, to move horizontally along the direction parallel to the conveying track, thereby driving the concrete placing machine 3 to pour concrete at different positions along the length of the mold. This allows the concrete placing machine 3 to place concrete at fixed points on the mold, meeting the requirements of concrete uniformity for large bridge precast components. At the same time, each pair of Z-axis drive components 2 independently drives the two pairs of concrete placing machines 3 to move along the Z-axis direction, that is, to move horizontally along the direction perpendicular to the conveying track. This allows one pair of concrete placing machines 3 to be placing concrete while the other pair is loading concrete through the concrete mixer truck or the discharge port of the batching plant during a single concrete placing operation. This reduces the number of loading and unloading operations of the concrete placing machine 3, improves the efficiency of concrete placing, and realizes continuous concrete placing operation. In this process, the X-axis drive assembly 1 drives the placing boom 3 to place concrete at fixed points, achieving uniform placement of concrete within the mold. The Z-axis drive assembly 2 further drives the two placing booms 3 to alternately perform placing operations, further improving the overall work efficiency and avoiding the problems of concrete accumulation or missing concrete that may occur in traditional placing methods. This improves the quality of precast bridge components. At the same time, the device also has the advantages of simple structure, convenient operation, and low maintenance cost. It is suitable for the production of precast bridge components of various scales and has broad market application prospects.

[0030] X-axis drive assembly 1 includes a vertical truss 11, an X-axis linear module 12 and an X-axis slide rail 13 mounted on the vertical truss 11, and a horizontal truss 14. The horizontal truss 14 is located at the moving end of the X-axis linear module 12 and slidably connected to the X-axis slide rail 13 of another X-axis drive assembly 1. The Z-axis drive assembly 2 is mounted on the horizontal truss 14. The vertical truss 11, as the main support structure, ensures the overall stability of the X-axis drive assembly 1. The X-axis linear module 12 provides the horizontal truss 14 with precise X-axis movement capability, enabling the Z-axis drive assembly 2 and the material placing machine 3 to be precisely positioned along the mold length. The horizontal truss 14 effectively connects the vertical truss 11 and the Z-axis drive assembly 2, acting as a connecting link and ensuring the transmission of force and the smoothness of movement. This design not only improves the stability of the device but also guarantees the accuracy and efficiency of the material placing operation. A pair of X-axis drive components 1 are respectively set on both sides of the conveying track, and the horizontal truss 14 of one X-axis drive component 1 is slidably connected to the X-direction slide rail 13 of the other X-axis drive component 1. This design forms a mutually supporting and guiding structure between the two X-axis drive components 1, further enhancing the stability and load-bearing capacity of the entire device. During the concrete placement operation, even when facing a large amount of concrete required for large bridge precast components, the device can maintain a stable working state to ensure the smooth progress of the concrete placement operation. At the same time, this design also facilitates the maintenance and adjustment of the device, improving its flexibility and applicability.

[0031] The Z-axis drive assembly 2 includes a Z-axis linear module 21 and a Z-axis slide rail 22 mounted on a horizontal truss 14, as well as an I-beam bracket 23. The Z-axis linear module 21 and the Z-axis slide rail 22 are mounted perpendicular to the conveyor track and span above it. The I-beam bracket 23 is located at the moving end of the Z-axis linear module 21 and slidably connected to the Z-axis slide rail 22. Two placing booms 3 are spaced apart on the I-beam bracket 23. The Z-axis linear module 21 provides precise Z-axis movement capability to the I-beam bracket 23, allowing the placing booms 3 to perform placing operations in a direction perpendicular to the conveyor track. The I-beam bracket 23 effectively connects the Z-axis linear module 21 and the placing booms 3, providing support and guidance, ensuring smooth vertical movement of the placing booms 3.

[0032] Reference Figure 2The fabric feeding machine 3 includes a frame 31 mounted on an I-beam support 23, a fabric hopper 32 mounted on the frame 31, a pair of vibrating motors 33 symmetrically mounted on both sides of the fabric hopper 32, a pair of discharge baffles 34 hinged to the fabric hopper 32 and having a magnetic coating 341, and a switch drive assembly 35 mounted on the pair of discharge baffles 34. The switch drive assembly 35 includes transmission gears 351 respectively mounted on the pair of discharge baffles 34 and meshing with each other, connecting rods 352 hinged to the discharge baffles 34, and a drive cylinder 353 hinged to one of the connecting rods 352 and with its piston rod hinged to the other connecting rod 352. The pair of discharge baffles 34 are driven by the drive cylinder 353 to rotate, selectively blocking the discharge port of the fabric hopper 32.

[0033] The placing hopper 32 is used to hold concrete materials. This arrangement, combined with the vibrating motor 33, ensures that the concrete materials within the placing hopper 32 receive uniform vibration, thereby further improving the uniformity and efficiency of the concrete placement. Simultaneously, this symmetrical arrangement enhances the stability of the placing hopper 32, preventing swaying or tilting during the placement process and ensuring the stability and reliability of the placement operation. When the piston rod of the drive cylinder 353 extends or retracts, it drives the two connecting rods 352 to swing. Since the two connecting rods 352 are meshed through a transmission gear 351, they swing synchronously and in opposite directions, thereby causing the discharge baffle 34 to flip synchronously and in opposite directions, realizing the opening and closing of the discharge port of the placing hopper 32. This design is not only simple in structure and easy to implement, but also has high transmission efficiency and fast response speed, ensuring the stability and reliability of the placing machine 3 during the placement process. Furthermore, by adjusting the extension or retraction of the drive cylinder 353, the flipping angle of the discharge baffle 34 can be precisely controlled, thereby achieving precise adjustment of the concrete flow rate and placement speed. The magnetic coating 341 allows the discharge baffle 34 to adhere more firmly to the discharge port of the hopper 32, preventing concrete material from slipping or dripping on the discharge baffle 34, thereby reducing concrete waste and improving the accuracy and efficiency of material distribution.
