Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a concrete pouring device. Background Technology

[0002] As a core material in modern construction, the quality of concrete vibration is directly related to the durability and safety of the structure. Traditional vibration operations rely heavily on manual experience, resulting in high labor intensity, significant quality fluctuations, and poor adaptability to complex working conditions. The industry has long faced challenges such as difficulty in controlling vibration parameters, low efficiency in air bubble removal, and insufficient uniformity. Especially in the pouring of complex structures such as curved surfaces and slopes, issues such as under-vibration, over-vibration, or surface defects are prone to occur. With the deepening of the concept of intelligent construction, concrete vibration technology is innovating towards automation and intelligence. By integrating sensing technology, intelligent algorithms, and precise control mechanisms, real-time monitoring and adaptive adjustment of the vibration process can be achieved, which has become a key path to improve construction quality and efficiency.

[0003] In the field of concrete construction, vibration is a crucial process for ensuring the density and surface smoothness of concrete. Traditional vibration equipment is mostly designed for flat pouring, and often suffers from insufficient adjustment capabilities and poor adaptability when facing complex conditions such as curved surfaces and slopes. For example, the utility model patent CN223062031U discloses a concrete vibration device that connects multiple vibrating elements through axial and radial insertion structures, aiming to ensure the consistency of compaction and smoothness on the same working surface. However, during use, the spacing between the vibration units of this device is fixed or has a limited adjustment range, making it impossible to flexibly arrange them according to the curvature of the surface or the slope of the slope. This can easily lead to uneven vibration coverage on complex geometric surfaces, resulting in missed or over-vibration. Furthermore, this device lacks an independent adjustment mechanism for the height of the vibration units, making it unable to adapt to changes in pouring thickness or terrain undulations. Especially when pouring on slopes, it is difficult to ensure consistent vibration depth at all points, affecting the overall compactness of the concrete. Therefore, we propose a concrete pouring device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a concrete pouring device, including a support frame and a vibration unit. Multiple sets of mounting frames are slidably installed on the support frame, and the multiple sets of vibration units are respectively installed on the corresponding mounting frames. The support frame is equipped with a spacing adjustment mechanism for driving the mounting frames to move along the support frame. Each of the multiple sets of mounting frames is provided with a height adjustment mechanism for independently adjusting the working height of the vibration unit. A controller is fixedly installed on the support frame.

[0005] In some embodiments, the spacing adjustment mechanism includes two sets of guide frames symmetrically distributed on the support frame. The two sets of guide frames are slidably connected to the support frame. The two outer sets of mounting frames are fixedly connected to the corresponding guide frames, and the multiple inner sets of mounting frames are slidably connected to the support frame and the guide frames.

[0006] In some embodiments, the spacing adjustment mechanism further includes a mounting rod fixedly mounted on a support frame. Two sets of symmetrically distributed first adjustment rods are slidably mounted on the mounting rod. A second adjustment rod is slidably mounted inside each of the two sets of first adjustment rods. The outer ends of the two sets of second adjustment rods are respectively fixedly connected to the corresponding guide frames. A bidirectional screw is rotatably mounted inside the mounting rod. A solenoid is rotatably mounted inside each of the two sets of first adjustment rods.

[0007] In some embodiments, the bidirectional screw has two sets of symmetrically distributed keyways, and two sets of symmetrically distributed key blocks are fixedly installed on each of the two sets of screw tubes. The key blocks and keyways are correspondingly arranged, and the screw tubes are slidably sleeved with the bidirectional screw through the key blocks and keyways. The two ends of the bidirectional screw pass through two sets of first adjusting rods and are threadedly connected to the two sets of first adjusting rods respectively. The two sets of screw tubes pass through corresponding second adjusting rods and are threadedly connected to the second adjusting rods respectively.

[0008] In some embodiments, two adjacent sets of mounting brackets are movably connected by a linkage assembly. The linkage assembly includes two sets of first connecting rods and second connecting rods that are distributed crosswise and hinged to each other at the middle. The lower ends of the two sets of first connecting rods are rotatably connected by a pivot, and the upper ends of the two sets of second connecting rods are rotatably connected by a pivot. A slider is rotatably mounted on the upper end of the two sets of first connecting rods. The slider is slidably connected to the corresponding mounting bracket. The lower ends of the two sets of second connecting rods are rotatably connected to the corresponding mounting brackets by pivots.

[0009] In some embodiments, the height adjustment mechanism includes a fixed frame slidably mounted on a mounting bracket. A lead screw is provided inside the mounting bracket. The two ends of the lead screw pass through the mounting bracket and are rotatably connected to the mounting bracket through rolling bearings. The lead screw passes through the fixed frame and is threadedly connected to the fixed frame. A fixing ring is fixedly sleeved on the vibrating unit. The fixing ring is fixedly connected to the fixed frame through bolts or other connecting parts.

[0010] In some embodiments, a distance sensor is fixedly installed on the vibration unit, and a flexible PZT composite film pressure sensor is fixedly embedded at the bottom of the vibration unit. The bottom of the vibration unit is sealed and protected by a welded sealing metal sheet to achieve sealing protection for the flexible PZT composite film pressure sensor.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. Through the established spacing adjustment mechanism, the operator can rotate the bidirectional screw to drive two sets of first adjusting rods to move synchronously in opposite directions along the mounting rod. The bidirectional screw, through a keyway and key block combination, drives two sets of solenoids to rotate synchronously, thereby driving two sets of second adjusting rods to extend or retract, ultimately causing the guide frames on both sides and all mounting frames to slide synchronously along the support frame. Combined with the connecting rod assembly between each mounting frame, this mechanism ensures that the spacing between multiple sets of vibration units always remains equidistant, achieving rapid, precise, and uniform adjustment of the vibration range width. This effectively improves construction efficiency and adaptability to working surfaces of different widths, overcoming the shortcomings of traditional devices with fixed or inconvenient spacing adjustments.

[0013] 2. By independently installing screw-driven height adjustment mechanisms on each mounting frame, operators can independently control the lifting height of each vibration unit. This design allows for setting different working heights for each vibration unit based on the specific terrain undulations, thickness variations, or slope gradient of the pouring area, such as keeping the vibrator vertical on slopes or reaching different depths, achieving personalized and precise control of the vibration depth. Combined with the distance measuring sensor installed on the vibration unit and the flexible PZT composite film pressure sensor integrated at the bottom, the system can monitor the vibration depth and concrete compaction status in real time, and achieve intelligent feedback and optimization through the controller, greatly improving the device's adaptability to complex pouring conditions and the overall vibration quality of the concrete.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a concrete pouring device, including a support frame 1 and a vibrating unit 4. Multiple sets of mounting frames 3 are slidably installed on the support frame 1, and the multiple sets of vibrating units 4 are respectively installed on corresponding mounting frames 3. A spacing adjustment mechanism 5 for driving the mounting frames 3 to move along the support frame 1 is installed on the support frame 1. Each of the multiple sets of mounting frames 3 is equipped with a height adjustment mechanism 6 for independently adjusting the working height of the vibrating unit 4. A controller 2 is fixedly installed on the support frame 1. The spacing adjustment mechanism 5 includes two sets of guide frames 501 symmetrically distributed on the support frame 1. The two sets of guide frames 501 are slidably sleeved with the support frame 1. The two outer sets of mounting frames 3 are respectively fixedly connected to the corresponding guide frames 501, and the multiple inner sets of mounting frames 3 are slidably connected to the support frame 1 and the guide frames 501. The spacing adjustment mechanism 5 is responsible for controlling the overall distribution width of all vibrating units 4, while the height adjustment mechanism 6 gives each vibrating unit 4 independent lifting and lowering capabilities to adapt to uneven working surfaces.

[0023] The spacing adjustment mechanism 5 further includes a mounting rod 502 fixedly mounted on the support frame 1. Two sets of symmetrically distributed first adjusting rods 503 are slidably mounted on the mounting rod 502. A second adjusting rod 504 is slidably mounted inside each set of first adjusting rods 503. The outer ends of the two sets of second adjusting rods 504 are respectively fixedly connected to the corresponding guide frame 501. A bidirectional screw 505 is rotatably mounted inside the mounting rod 502. A solenoid 507 is rotatably mounted inside each set of first adjusting rods 503. Two sets of symmetrically distributed... The keyway 506 has two sets of symmetrically distributed key blocks 508 fixedly installed on each of the two sets of solenoids 507. The key blocks 508 and keyways 506 are correspondingly arranged. The solenoids 507 are slidably sleeved with the bidirectional screw 505 through the key blocks 508 and keyways 506. The two ends of the bidirectional screw 505 pass through two sets of first adjusting rods 503 and are threadedly connected to the two sets of first adjusting rods 503 respectively. The two sets of solenoids 507 pass through corresponding second adjusting rods 504 and are threadedly connected to the second adjusting rods 504 respectively. When the spacing is adjusted, the bidirectional screw 505 is driven to rotate. Since the two ends of the bidirectional screw 505 are threadedly connected to the two sets of first adjusting rods 503, it can drive the two sets of first adjusting rods 503 to move synchronously in opposite directions along the mounting rod 502. When the bidirectional screw 505 rotates, it engages with the key blocks 508 on the solenoids 507 through the keyway 506, driving the two sets of solenoids 507 to rotate synchronously. Since the solenoid 507 and the second adjusting rod 504 are threadedly connected, the rotating solenoid 507 drives the second adjusting rod 504 to extend or retract, thereby pushing or pulling the guide frames 501 on both sides to slide along the support frame 1.

[0024] The two adjacent sets of mounting frames 3 are movably connected by a linkage assembly. The linkage assembly includes two sets of first connecting rods 509 and second connecting rods 510 that are distributed crosswise and hinged to each other in the middle. The lower ends of the two sets of first connecting rods 509 are rotatably connected by a pivot, and the upper ends of the two sets of second connecting rods 510 are rotatably connected by a pivot. A slider 511 is rotatably mounted on the upper end of the two sets of first connecting rods 509. The slider 511 is slidably connected to the corresponding mounting frame 3. The lower ends of the two sets of second connecting rods 510 are rotatably connected to the corresponding mounting frames 3 by pivots. All mounting frames 3 are linked together by the linkage assembly, which constitutes a scaling mechanism to ensure that the spacing between each mounting frame 3 remains equidistant when the guide frame 501 moves, thereby achieving uniform adjustment of the coverage width of multiple sets of vibrating units 4.

[0025] Example 2:

[0026] Please see Figure 5The height adjustment mechanism 6 includes a fixed frame 601 slidably mounted on the mounting frame 3. The mounting frame 3 is provided with a lead screw 602. The two ends of the lead screw 602 pass through the mounting frame 3 and are rotatably connected to the mounting frame 3 through rolling bearings. The lead screw 602 passes through the fixed frame 601 and is threadedly connected to the fixed frame 601. A fixing ring 603 is fixedly sleeved on the vibrating unit 4. The fixing ring 603 is fixedly connected to the fixed frame 601 through bolts or other connecting parts. When the height is adjusted independently, the motor on each mounting frame 3 drives the lead screw 602 to rotate. The rotation of the lead screw 602 drives the fixed frame 601, which is threaded with it, to rise and fall in the vertical direction, thereby driving the vibrating unit 4 connected to it through the fixing ring 603 to descend or rise, so as to independently set its working height.

[0027] A distance measuring sensor 7 is fixedly installed on the vibration unit 4, and a flexible PZT composite film pressure sensor 8 is fixedly embedded in the bottom of the vibration unit 4. The bottom of the vibration unit 4 is sealed and protected by a welded sealing metal sheet 9. During operation, the distance measuring sensor 7 on the vibration unit 4 detects its relative height to the pouring surface in real time, providing data feedback for precise control. At the same time, the flexible PZT composite film pressure sensor 8 at its bottom can sense the pressure change and compaction status when the vibrating head contacts the concrete, and transmit the signal to the controller 2. The controller 2 can intelligently judge the concrete vibration status based on this, and can output signals to guide the operator or automatically adjust the vibration parameters to ensure that the best vibration effect can be achieved under different terrains and thicknesses.
