Description

Technical Field

[0001] This utility model relates to equipment for producing precast concrete components, and more particularly to a vibration device for precast components. Background Technology

[0002] In modern infrastructure construction, precast components are widely used due to their advantages such as fast construction speed and controllable quality. The precast component manufacturing process includes steps such as mold cleaning, mold spraying with release agent, steel cage placement, concrete pouring and vibration, curing, and component demolding. Concrete pouring vibration is a crucial step. Traditional vibration methods mostly involve manual immersion vibrators, which suffer from drawbacks such as slow speed, high labor intensity, and inconsistent vibration quality. To address this, existing technologies have proposed using a simplified vibration table, placing the mold after concrete pouring on the table for vibration. This overcomes some of the shortcomings of manual immersion vibrators, but it is prone to frequent mold displacement on the vibration table, which can also lead to significant noise during vibration.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Figures 1 to 3 This illustration shows one embodiment of the precast component vibration device of the present invention. The device includes a vibration base frame 1 and liftable conveying mechanisms 2 located on both sides of the vibration base frame 1. Two bottom vibration platforms 3 are mounted on the vibration base frame 1, and a buffer assembly 4 is provided between the vibration base frame 1 and the bottom vibration platforms 3. Each bottom vibration platform 3 is equipped with a bottom vibration drive component 31 and a bottom clamping mechanism 32. Of course, in other embodiments, the number of bottom vibration platforms 3 can be adjusted to match the overall production cycle of the precast component production line.

[0024] In this embodiment of the precast component vibration device, after the mold 6 is transferred from the upstream station to the conveying mechanism 2, the conveying mechanism 2 descends, allowing the mold 6 to be supported by the bottom vibration platform 3. The bottom clamping mechanism 32 clamps the mold 6, and then concrete is poured into the mold 6. At this time, the bottom vibration drive 31 is activated to assist the pouring process. After pouring, the bottom vibration drive 31 remains in a vibrating state to compact the concrete. The buffer component 4 can act as a buffer to prevent vibration from being transmitted to the vibration base 1. After vibration is complete, the bottom clamping mechanism 32 releases the mold 6, and the conveying mechanism 2 rises to lift the mold 6 from the bottom vibration platform 3 and transport the mold 6 to the downstream station. The precast component vibration device in this embodiment has a simple structure, is easy to connect with upstream and downstream stations, and the bottom clamping mechanism 32 clamps and fixes the mold 6, which can improve the vibration transmission efficiency, prevent mold displacement, and reduce the noise generated.

[0025] Furthermore, in this embodiment, the bottom clamping mechanism 32 includes bottom grippers 321 (preferably hinged to the bottom vibration platform 3) located on both sides of the bottom vibration platform 3 and a bottom gripper drive member 322 for driving the bottom grippers 321 to rotate up and down. The bottom vibration platform 3 is provided with a channel 33 for the bottom grippers 321 to extend out. After the mold 6 is supported by the bottom vibration platform 3, the bottom gripper drive member 322 drives the bottom grippers 321 on both sides to rotate upward and move closer together, thereby holding the mold 6 tightly on the bottom vibration platform 3; conversely, after vibration is completed, the bottom gripper drive member 322 drives the bottom grippers 321 on both sides to rotate downward and move away from each other, so that they can be disengaged from the mold 6. The structure is simple and effective.

[0026] Furthermore, in this embodiment, the bottom gripper drive member 322 is a telescopic structure (e.g., it can be a cylinder, hydraulic cylinder, or electric push rod, etc.), and both ends of the bottom gripper drive member 322 are respectively hinged to the bottom grippers 321 on both sides. The bottom grippers 321 on both sides can be driven to rotate up and down by the extension and retraction of the bottom gripper drive member 322, which is simple and reliable.

[0027] Furthermore, in this embodiment, the buffer assembly 4 includes multiple helical springs 41. Both the vibration base 1 and the bottom vibration platform 3 are provided with connecting portions 42 (e.g., connecting bosses, connecting columns, or sleeves). The two ends of the helical springs 41 are sleeved one-to-one with the connecting portions 42. Either the helical springs 41 are sleeved around the outer periphery of the connecting portions 42, or the connecting portions 42 are sleeved around the outer periphery of the helical springs 41. The helical springs 41 provide good buffering, preventing vibration from being transmitted to the vibration base 1. The sleeved structure ensures high reliability and facilitates disassembly and maintenance.

[0028] Furthermore, in this embodiment, a side vibration mechanism 5 is also provided on the side of the conveying mechanism 2 away from the vibrating base frame 1. That is, the side vibration mechanism 5 is located on the outside of the conveying mechanism 2. The side vibration mechanism 5 is correspondingly arranged with the bottom vibration platform 3 so that the side vibration mechanism 5 vibrates the side of the mold on the bottom vibration platform 3. This is suitable for precast components with higher height, so that the precast components are fully vibrated and compacted, thereby improving the quality of the precast components.

[0029] Further, in this embodiment, the side vibration mechanism 5 includes a side vibration base 51 (preferably, the side vibration base 51 is connected to the vibration base 1 as a whole by fasteners, etc.; of course, in other embodiments, the side vibration base 51 can also be independently fixed to the factory floor), a rotating bracket 52 (e.g., hinged to the side vibration base 51) disposed on the side vibration base 51, and a rotating drive component 53 (e.g., a cylinder, hydraulic cylinder, or electric push rod, etc., with both ends hinged to the side vibration base 51 and the rotating bracket 52 respectively, which can drive the rotating bracket 52 to rotate up and down by extension and retraction) for driving the rotating bracket 52 to rotate up and down, and a side vibration platform 54 disposed on the rotating bracket 52, on which a side vibration drive component 56 is disposed. See details. Figure 2 and Figure 3 After the mold 6 is held tightly to the bottom vibration platform 3, the rotating drive component 53 drives the rotating bracket 52 to rotate upward, so that the side vibration platform 54 clamps the mold 6 from the left and right sides. Then the side vibration drive component 56 is started to vibrate the side of the mold 6, so that the precast components with higher height can be fully vibrated and compacted, improving the quality of the precast components. The structure is simple and effective.

[0030] Furthermore, in this embodiment, the side vibration platform 54 is hinged to the rotating bracket 52. The side vibration platform 54 can rotate relative to the rotating bracket 52, thereby closely adhering to the side of the mold 6 and effectively clamping the mold 6. The structure is simple and effective.

[0031] In this embodiment, the side vibration mechanism 5 includes a side clamping mechanism 55, which includes side grippers 551 disposed on the front and rear sides of the side vibration platform 54 and a side gripper drive member 552 for driving the side grippers 551 to rotate back and forth. See details. Figure 1After the side vibration platform 54 clamps the mold 6 from the left and right sides, the side gripper drive 552 drives the side grippers 551 to move closer from the front and rear sides, which can directly move the mold 6 in the front and rear direction to further fix the mold 6. Here, the left and right direction is the width direction or transverse direction of the conveying mechanism 2, and the front and rear direction is the length direction or conveying direction of the conveying mechanism 2.

[0032] In a preferred embodiment, the vibration frequency of the bottom vibration drive 31 is adjustable, and preferably, the vibration frequency of the side vibration drive 56 is also adjustable. When concrete is poured into the mold 6, the bottom vibration drive 31 and the side vibration drive 56 vibrate at low frequency to assist in the pouring; after the pouring is completed, the bottom vibration drive 31 and the side vibration drive 56 vibrate at high frequency, which helps to make the concrete denser and improve the quality of the precast components.

[0033] Furthermore, in this embodiment, the conveying mechanism 2 includes a conveying support 21, a conveying component 22 (e.g., rollers, bars, or chains) disposed on the conveying support 21, and a lifting drive component 23 (e.g., cylinder, hydraulic cylinder, or electric push rod) for driving the conveying support 21 to rise and fall. The lifting drive component 23 drives the conveying component 22 to rise and fall through the conveying support 21, thereby transferring the mold 6 to the bottom vibration platform 3, or lifting the mold 6 from the bottom vibration platform 3. The structure is simple and reliable.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
