Description

Technical Field

[0001] This application relates to the technical field of construction equipment for precast concrete components in civil engineering, and in particular to a vibration damping device for the concrete pouring and vibration process in precast T-beams. Background Technology

[0002] In the pouring and vibration construction of precast T-beam concrete, vibrators are often used to compact the concrete to improve its density. When the vibrator is working, it will generate strong vibrations. If it is directly fixed to the T-beam formwork or steel structure, it will easily lead to formwork displacement, steel deformation or fatigue damage at the connection, affecting the construction quality and structural safety.

[0003] However, it has been found in the existing technology that due to the different sizes and specifications of the molds, the height of the construction platform is different, and most of the existing technologies use concrete fixed bases, which makes it impossible to adjust the height of the vibratory body and results in insufficient adaptability. Utility Model Content

[0004] The purpose of this application is to provide a vibration damping device for the concrete pouring and vibration process in precast T-beams, which has the advantages of easy adjustment of the height of the vibrator to adapt to construction platforms of different heights and ensure that the device can be placed horizontally, thus solving the problems mentioned in the background art.

[0005] This application provides a vibration damping device for the concrete pouring and vibration process in precast T-beams, employing the following technical solution: It includes adjustable bases arranged at equal intervals and two vibrating bodies. Each adjustable base includes a bottom plate, and each bottom plate has a top plate above it. A sleeve is fixedly connected to the upper surface of each bottom plate. A sliding rod is slidably connected to the inner wall of each sleeve. The top end of each sliding rod is fixedly connected to the bottom surface of the top plate. A limiting rod is fixedly installed on the upper surface of each top plate. A bidirectional threaded rod is rotatably connected to the inner wall of each limiting rod. Two sliders are slidably connected to the inner wall of each limiting rod. The inner wall of each slider is threadedly connected to the outer surface of the corresponding bidirectional threaded rod. A first limiting block is fixedly connected to the upper surface of each slider. A connecting rod is rotatably connected to the outer surface of each first limiting block. A second limiting block is rotatably connected to the other end of each connecting rod. The upper surface of each second limiting block is fixedly connected to the bottom surface of the corresponding top plate.

[0006] By adopting the above technical solution, a base plate and a top plate are set up, and sleeves and sliding rods are installed in the quality inspection chambers of the base plate and the top plate. The sleeves and sliding rods are set as sliding connections, which allows the top plate to rise and fall stably. A limiting rod is set on the upper surface of the base plate, and a double-threaded rod is installed on the inner wall of the limiting rod. The double-threaded rod and the limiting rod are set as rotating connections to limit the double-threaded rod. Two sliders are set on the inner wall of the limiting rod to limit the sliders. The sliders and the double-threaded rod are set as threaded connections, so that when the operator rotates the double-threaded rod, it can drive the corresponding sliders to move relative to each other. A first limiting block is set on the upper surface of the slider, and a second limiting block is set on the bottom surface of the top plate. A connecting rod is set to connect the first limiting block and the second limiting block, so that when the slider moves, the connecting rod can drive the top plate to rise and fall, thereby facilitating the adjustment of the height of the vibrator to adapt to construction platforms of different heights and ensuring that the equipment is placed horizontally.

[0007] Preferably, each of the top plates has two guide rails fixedly connected to its upper surface, and each guide rail has a sliding seat slidably connected to its outer surface. The side of each sliding seat that is close to each other is fixedly connected to the outer surface of the corresponding vibrating body.

[0008] By adopting the above technical solution, a guide rail is set on the upper surface of the corresponding top plate to support and fix the guide rail. The slide block is installed on the outer surface of the guide rail and set as a sliding connection to limit the movement of the slide block. The slide block is fixed to the corresponding vibrating body so that the slide block can move together with the vibrating body.

[0009] Preferably, each of the slides has two fixed blocks fixedly connected to its upper surface, and each of the fixed blocks has a rotating block rotatably connected to its outer surface.

[0010] By adopting the above technical solution, the fixed block is installed on the upper surface of the slide, and the rotating block is set on the outer surface of the fixed block, forming a rotating connection to achieve the limiting of the rotating block.

[0011] Preferably, a damping rod is fixedly connected to the upper surface of each of the rotating blocks, and a fixing plate is fixedly connected to the top of each of the damping rods.

[0012] By adopting the above technical solution, the damping rod is installed on the upper surface of the rotating block, and the fixing plate is installed on the top of the damping rod to form a fixed connection, so that the damping rod can be fixed between the rotating block and the fixing plate.

[0013] Preferably, a spring is fixedly connected to the bottom surface of each of the fixed plates, and the bottom end of each spring is fixedly connected to the upper surface of the corresponding rotating block.

[0014] By adopting the above technical solution, the spring is installed on the bottom surface of the fixed plate, and the bottom end of the spring is connected to the corresponding rotating block, so that the rotating block and the fixed plate can achieve shock absorption by installing a damping rod and the spring.

[0015] Preferably, each of the vibrating bodies has a connecting frame fixedly connected to the side of each other that is far apart from each other, and the bottom surface of each connecting frame is fixed to the upper surface of the corresponding fixing plate by bolts.

[0016] By adopting the above technical solution, the connecting frame is installed on the side of the vibrating body that is far away from each other, and the bottom surface of the connecting frame is connected to the corresponding fixed plate. This allows the vibrating body to absorb the vibration generated during operation through the damping rod and spring, greatly reducing the vibration energy transmitted to the T-beam structure.

[0017] Preferably, each of the vibratory bodies has vibrators arranged at equal intervals fixedly installed on the side away from each other, and a precast T-beam mold is provided between the two vibratory bodies.

[0018] By adopting the above technical solution, the vibrator is installed on the side of the vibrating body that is far apart from each other and is set as a fixed connection to realize the installation of the vibrator. The vibrator can vibrate the concrete. A precast T-beam mold is set between the vibrating bodies, and the T-shaped precast beam can be poured through the precast T-beam mold.

[0019] Preferably, a first mounting seat is fixedly connected to the upper surface of each of the two top plates, a hydraulic rod is rotatably connected to the outer surface of each first mounting seat, a second mounting seat is rotatably connected to the other end of each hydraulic rod, and the outer surface of each second mounting seat is fixedly connected to the outer surface of the corresponding vibrating body.

[0020] By adopting the above technical solution, the first mounting seat is installed on the upper surface of the corresponding top plate, and a hydraulic rod is set on the outer surface of the first mounting seat. By setting the second mounting seat at the other end of the hydraulic rod, the surface of the second mounting seat is fixed to the vibrating body, so that when the hydraulic rod extends and retracts, it can drive the vibrating body and the vibrator to move, thereby enabling them to be aligned with the area to be vibrated and facilitating the adjustment of the horizontal position of the vibrator.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This device is a vibration damping mechanism for concrete pouring and vibration in precast T-beams. It comprises a sleeve, a bidirectional threaded rod, a slider, and a connecting rod. Rotating the bidirectional threaded rod connects it to the slider, allowing the slider to slide relative to the inner wall of a limiting rod. This causes the slider to move a corresponding first limiting block. The connection between the first limiting block, the connecting rod, and the second limiting block allows for the raising and lowering of the top plate. The sleeve and the sliding rod ensure stable raising and lowering of the top plate, facilitating adjustment of the vibratory body's height to accommodate construction platforms of varying heights and ensuring horizontal placement of the equipment. A connecting frame is installed on the outside of the vibratory body and fixed to a corresponding fixed plate. A sliding block is fixed to a fixed block, and a rotating block is connected to the fixed block. A damping rod and spring are installed between the rotating block and the fixed plate. This design effectively attenuates the vibration transmitted from the vibrator to the T-beam, preventing damage to the precast T-beam mold and reinforcing steel, and improving concrete pouring quality and construction safety.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0025] Example 1: A vibration damping device for the concrete pouring and vibration process inside precast T-beams. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 The system includes adjustable bases 1 arranged at equal intervals and two vibrating bodies 9. Each adjustable base 1 includes a base plate 101, and a top plate 102 is provided above each base plate 101. A sleeve 103 is fixedly connected to the upper surface of each base plate 101, and a sliding rod 104 is slidably connected to the inner wall of each sleeve 103. The top end of each sliding rod 104 is fixedly connected to the bottom surface of the top plate 102. By setting the base plate 101 and the top plate 102, and setting the sleeve 103 and sliding rod 9 in the inspection chamber of the base plate 101 and the top plate 102, the system achieves this configuration. 04. The sleeve 103 and the slide rod 104 are set to a sliding connection so that the top plate 102 can be raised and lowered stably. Each top plate 102 has a limit rod 105 fixedly installed on its upper surface. Each limit rod 105 has a bidirectional threaded rod 106 rotatably connected to its inner wall. The limit rod 105 is set on the upper surface of the bottom plate 101, and the bidirectional threaded rod 106 is installed on the inner wall of the limit rod 105. The bidirectional threaded rod 106 and the limit rod 105 are set to a rotatable connection to limit the bidirectional threaded rod 106.

[0026] Please see Figure 1 , Figure 3 and Figure 4 Each limiting rod 105 has two sliders 107 slidably connected to its inner wall. The inner wall of each slider 107 is threadedly connected to the outer surface of the corresponding bidirectional threaded rod 106. The two sliders 107 on the inner wall of the limiting rod 105 limit the movement of the sliders 107. The sliders 107 and the bidirectional threaded rod 106 are threaded together, allowing the operator to rotate the bidirectional threaded rod 106 and move the corresponding sliders 107 relative to it. A first limiting block 108 is fixedly connected to the upper surface of each slider 107, and a connecting rod 1 is rotatably connected to the outer surface of each first limiting block 108. 09. Each connecting rod 109 has a second limiting block 110 rotatably connected to the other end. The upper surface of each second limiting block 110 is fixedly connected to the bottom surface of the corresponding top plate 102. A first limiting block 108 is set on the upper surface of the slider 107, and the second limiting block 110 is set on the bottom surface of the top plate 102. By connecting the connecting rod 109 to the first limiting block 108 and the second limiting block 110, when the slider 107 moves, the connecting rod 109 can drive the top plate 102 to rise and fall, thereby facilitating the adjustment of the height of the vibrator 9 to adapt to construction platforms of different heights and ensure that the equipment is placed horizontally.

Figure 1 , Figure 2 and Figure 5Each top plate 102 has two guide rails 2 fixedly connected to its upper surface. Each guide rail 2 has a sliding block 3 slidably connected to its outer surface. The sides of each sliding block 3 that are close to each other are fixedly connected to the outer surface of the corresponding vibrating body 9. The guide rails 2 are positioned on the upper surface of the corresponding top plate 102 to support and fix them. The sliding blocks 3 are installed on the outer surface of the guide rails 2, forming a sliding connection to limit their movement. The sliding blocks 3 are fixedly connected to the corresponding vibrating body 9, allowing them to move together. Each sliding block 3 has two... Fixed blocks 4, each with a rotating block 5 rotatably connected to its outer surface. Fixed blocks 4 are mounted on the upper surface of slide block 3, and rotating blocks 5 are set on the outer surface of fixed blocks 4, forming a rotatable connection to limit the movement of rotating blocks 5. A damping rod 6 is fixedly connected to the upper surface of each rotating block 5, and a fixing plate 7 is fixedly connected to the top of each damping rod 6. The damping rod 6 is mounted on the upper surface of rotating block 5, and the fixing plate 7 is mounted on the top of the damping rod 6, forming a fixed connection so that the damping rod 6 can be fixed between the rotating block 5 and the fixing plate 7.

[0028] Please see Figure 2 , Figure 5 and Figure 6 Each fixed plate 7 has a spring 8 fixedly connected to its bottom surface. The bottom end of each spring 8 is fixedly connected to the upper surface of the corresponding rotating block 5. The spring 8 is installed on the bottom surface of the fixed plate 7 and the bottom end of the spring 8 is connected to the corresponding rotating block 5, so that the rotating block 5 and the fixed plate 7 can achieve vibration reduction through the installation of damping rods 6 and springs 8. Each vibrating body 9 has a connecting frame 10 fixedly connected to its opposite side. The bottom surface of each connecting frame 10 is fixed to the upper surface of the corresponding fixed plate 7 by bolts. The connecting frame 10 is installed on the opposite side of the vibrating body 9 and the bottom surface of the connecting frame 10 is connected to the corresponding fixed plate 7, so that when the vibrating body 9 vibrates, the vibration generated during operation can be absorbed by the damping rods 6 and springs 8, greatly reducing the vibration energy transmitted to the T-beam structure.

[0029] Please see Figure 2 , Figure 5 and Figure 6Each vibrating body 9 has a vibrator 11 fixedly installed on its opposite side, arranged at equal intervals. A precast T-beam mold 15 is set between two vibrating bodies 9. The vibrators 11 are installed on the opposite sides of the vibrating bodies 9 and are fixedly connected to achieve the installation of the vibrators 11. The vibrators 11 can vibrate the concrete. The precast T-beam mold 15 is set between the vibrating bodies 9, and the T-shaped precast beam can be poured through the precast T-beam mold 15. The upper surfaces of the two top plates 102 are fixedly connected to the first mounting base 12, and the outer surface of each first mounting base 12 is rotatably connected to the hydraulic rod 1. 3. Each hydraulic rod 13 is rotatably connected to a second mounting seat 14 at the other end. The outer surface of each second mounting seat 14 is fixedly connected to the outer surface of the corresponding vibrating body 9. The first mounting seat 12 is installed on the upper surface of the corresponding top plate 102, and the hydraulic rod 13 is set on the outer surface of the first mounting seat 12. By setting the second mounting seat 14 at the other end of the hydraulic rod 13, the surface of the second mounting seat 14 is fixed to the vibrating body 9, so that when the hydraulic rod 13 extends and retracts, it can drive the vibrating body 9 and the vibrator 11 to move, so that they can be aligned with the area to be vibrated, and the horizontal position of the vibrator 11 can be adjusted.

[0030] The implementation principle of this application embodiment is as follows: First, the adjustable base 1 is installed in a designated position. Then, the corresponding bidirectional threaded rod 106 is rotated, allowing the corresponding slider 107 to move. The slider 107 drives the corresponding first limiting block 108 to move. Through the connection of the first limiting block 108, the connecting rod 109, and the second limiting block 110, the top plate 102 can be raised and lowered, thereby achieving the effect of height adjustment. Then, the corresponding fixing plate 7 is fixed to the connecting frame 10, so that the vibrator 9 can be installed on the corresponding adjustable base 1, thereby facilitating the adjustment of the height of the vibrator 9 to suit various needs. For construction platforms of different heights, ensure the equipment is placed horizontally. Position the vibrator 9 on both sides of the precast T-beam mold 15. After the precast T-beam mold 15 is filled with concrete, activate the corresponding hydraulic rod 13 to move the vibrator 9, thereby allowing the vibrator 11 to move and be aligned with the area to be vibrated. This facilitates adjustment of the horizontal position of the vibrator 11. During vibration, the damping rod 6 and spring 8 effectively attenuate the vibration transmitted from the vibrator 11 to the T-beam, preventing damage to the precast T-beam mold 15 and reinforcing bars, and improving the quality of concrete pouring and construction safety.
