Description

Technical Field

[0001] This application relates to the field of concrete vibration compaction technology, and in particular to a vibrator for pouring concrete for walls and columns. Background Technology

[0002] As the core load-bearing components of a building, the quality of concrete pouring for walls and columns directly affects the overall safety and durability of the building. Concrete vibration is a crucial step in the wall and column pouring process. Vibration removes air bubbles from the concrete, promotes uniform aggregate distribution, and thus improves the concrete's density and mechanical properties. Currently, the industry commonly uses immersion vibrators for wall and column concrete vibration. The "fast insertion, slow withdrawal" method, recognized as an efficient vibration technique, relies on precisely controlling the insertion and withdrawal speeds of the vibrator to achieve thorough air removal and dense compaction of the concrete.

[0003] However, traditional immersion vibrators lack an independent speed control mechanism, and the insertion and withdrawal speeds rely on the operator's experience for control. This results in insufficient precision in the control of insertion and withdrawal speeds, which can easily lead to the formation of cavities or trapped air bubbles inside the concrete. This can cause defects such as holes and honeycombs in the concrete, seriously affecting the quality of the concrete and potentially having an adverse impact on the load-bearing capacity of walls and columns and the service life of buildings. Utility Model Content

[0004] The purpose of this application is to provide a vibrator for concrete pouring of walls and columns. Through the meshing transmission of the worm and worm wheel in the adjustable damping component, combined with the rotating handle, the damping force can be precisely adjusted. This allows the rubber damping block to apply controllable frictional resistance to the wear-resistant block, thereby precisely controlling the moving speed of the component box driven by the meshing of the gear and rack. This solves the problems mentioned in the background art.

[0005] This application provides a vibrator for concrete pouring of walls and columns, employing the following technical solution: It includes a support frame, a rotating box rotatably connected to the inner side of the support frame, a component box disposed inside the rotating box, a transmission flexible shaft fixedly installed inside the component box, a rack fixedly connected to the outer side of the component box, a rotating shaft rotatably connected to the inner side of the rotating box, a gear fixedly connected to one end of the rotating shaft, the gear meshing with the rack, a wear-resistant block fixedly connected to the outer side of the rotating shaft, and an adjustable damping assembly disposed outside the rotating box. The adjustable damping assembly includes a fixed seat fixedly connected to the outer side of the rotating box, an internally threaded sleeve rotatably connected to the inner side of the fixed seat, a lead screw threadedly connected to the inner side of the internally threaded sleeve, a connecting block fixedly connected to one end of the lead screw, and a rubber damping block fixedly connected to the upper side of the connecting block, the rubber damping block and the wear-resistant block being compatible.

[0006] By adopting the above technical solution, the gear and rack mechanism enables the component box to rotate when moving up and down, thus driving the shaft to rotate. Simultaneously, the interaction between the internal threaded sleeve, lead screw, connecting block, and rubber damping block in the adjustable damping component allows the rotation of the internal threaded sleeve to drive the lead screw, connecting block, and rubber damping block to adjust their height. This, in turn, adjusts the squeezing force of the rubber damping block on the wear-resistant block, thereby regulating the shaft speed. This allows operators to precisely control the insertion and withdrawal speed of the vibrator, preventing the retention of cavities or air bubbles inside the concrete due to improper speed, thus reducing voids and honeycomb defects and improving the density and overall quality of the concrete.

[0007] Preferably, the adjustable damping assembly further includes two fixed plates fixedly connected to the outside of the rotating box, with a worm gear rotatably connected to the inner side of the two fixed plates, and a worm wheel fixedly connected to the outer side of the internal threaded sleeve. The worm gear and the worm wheel mesh with each other, and a handle rotatably connected to the outer side of one of the fixed plates. The rotating end of the handle is fixedly connected to the rotating end of the worm gear.

[0008] By adopting the above technical solution, the meshing structure of the worm and worm wheel allows the operator to fine-tune the damping force through the handle, enhancing the stability and accuracy of speed control, reducing reliance on the operator's experience, and further preventing the formation of internal defects in the concrete. At the same time, the self-locking characteristics of both the worm and worm wheel ensure the stability after the damping force is finely adjusted.

[0009] Preferably, a vibrating head is fixedly connected to one end of the transmission flexible shaft, the vibrating head has a tapered outer shape, and a vibrator body is fixedly installed at the other end of the transmission flexible shaft.

[0010] By adopting the above technical solution, the conical vibrator head is easy to insert into the concrete, and the vibrator body efficiently transmits vibration energy through the transmission flexible shaft, effectively expelling air bubbles and voids, and improving the compaction effect of the concrete.

[0011] Preferably, a first guide groove is provided on the outer side of the rotating box, and the outer side of the connecting block is slidably connected to the inner side of the first guide groove.

[0012] By adopting the above technical solution, the first guide groove can guide the movement of the connecting block, thereby ensuring stable contact between the rubber damping block and the wear-resistant block, maintaining stable damping force, thus ensuring the uniformity of insertion and extraction speeds and avoiding local defects in the concrete.

[0013] Preferably, the outer side of the rotating box is provided with two sets of symmetrical second guide grooves, and the outer side of the component box is fixedly connected with two symmetrical sliders, and the outer side of the sliders is slidably connected to the inner side of the second guide grooves.

[0014] By adopting the above technical solution, the cooperation between the second guide groove and the slider enables the component box to move smoothly within the rotating box, thereby controlling the extension distance of the vibrating head and further improving the practicality of the device.

[0015] Preferably, the rotating box is provided with a top plate on its upper side, the bottom surface of the top plate is fixedly connected to the upper surface of the component box, and two handles are fixedly connected to the outer side of the top plate, with the outer side of each handle covered with a rubber protective sleeve.

[0016] By adopting the above technical solution, the handle provides a comfortable grip, while the external rubber protective cover can play a non-slip role, making it easier for operators to stably control the vibrator.

[0017] Preferably, a fixed bracket is fixedly provided on the inner side of the component box, and the transmission flexible shaft is fixedly connected to the inner side of the component box through the fixed bracket.

[0018] By adopting the above technical solution, the fixed bracket fixes the transmission flexible shaft inside the component box to prevent displacement during vibration, ensures that vibration energy is efficiently transmitted to the vibrating head, and improves the compaction effect and overall quality of concrete.

[0019] Preferably, two foot pedals are fixedly connected to the outer side of the support frame, and the outer side of both foot pedals is provided with anti-slip texture.

[0020] By adopting the above technical solution, the foot pedal provides a stable standing platform for the operator. The anti-slip texture reduces the risk of slipping. When the operator steps on the foot pedal, the weight of the operator can be used to improve the stability of the support frame, ensuring stable insertion and withdrawal of the vibrator, improving the speed control accuracy, and thus avoiding problems such as concrete cavities and air bubbles.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This vibrator for concrete pouring of walls and columns utilizes the meshing transmission of a worm gear and worm wheel in an adjustable damping assembly, combined with a rotating handle, to achieve precise fine-tuning of the damping force. This allows the rubber damping block to apply controllable frictional resistance to the wear-resistant block, thereby accurately controlling the moving speed of the component box driven by the gear and rack meshing. This solves the problem of inaccurate insertion or withdrawal speed caused by the reliance on manual experience in traditional vibrators. At the same time, the first and second guide grooves respectively constrain the movement trajectory of the connecting block and the slider, enabling the component box to move in an directional manner. This ensures that the vibrating head moves precisely in the concrete, further reducing the occurrence of voids and honeycomb, and improving the density and overall quality of the concrete through overall coordination.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A vibrator for concrete pouring of walls and columns, please refer to... Figures 1 to 5The system includes a support frame 1, with a rotating box 2 rotatably connected to the inner side of the support frame 1. The rotating box 2 allows the operator to drive the vibrating head 11 to change position, thereby increasing the vibration area of ​​the concrete. A component box 3 is located inside the rotating box 2, and a transmission flexible shaft 4 is fixedly installed inside the component box 3. One end of the transmission flexible shaft 4 is fixedly connected to the vibrating head 11, which has a conical outer shape. The other end of the transmission flexible shaft 4 is fixedly installed with the vibrator body 12. The conical structure of the vibrating head 11 facilitates insertion into the concrete, and the conical structure reduces the generation of air bubbles. Simultaneously, the vibrator body 12 efficiently transmits vibration energy through the transmission flexible shaft 4, effectively expelling air bubbles and voids, and improving the compaction effect of the concrete. A rack 5 is fixedly connected to the outer side of the component box 3, and a rotating shaft 6 is rotatably connected to the inner side of the rotating box 2. One end of the rotating shaft 6 is fixedly connected to a gear 7. The gear 7 and the rack... The rotating shaft 6 is fixedly connected to the outer side of the five-phase meshing mechanism. An adjustable damping assembly 9 is provided on the outer side of the rotating box 2. The adjustable damping assembly 9 includes a fixed seat 901 fixedly connected to the outer side of the rotating box 2. An internal threaded sleeve 902 is rotatably connected to the inner side of the fixed seat 901. A lead screw 903 is threadedly connected to the inner side of the internal threaded sleeve 902. A connecting block 904 is fixedly connected to one end of the lead screw 903. A rubber damping block 905 is fixedly connected to the upper side of the connecting block 904. The rubber damping block 905 and the wear-resistant block 8 are compatible. Under the cooperation of the internal threaded sleeve 902, the lead screw 903, the connecting block 904 and the rubber damping block 905, the rotation of the internal threaded sleeve 902 can drive the lead screw 903, the connecting block 904 and the rubber damping block 905 to adjust their height. This allows the rubber damping block 905 to adjust the squeezing force of the wear-resistant block 8, thereby adjusting the rotation speed of the rotating shaft 6.

[0032] Please refer to Figure 1 and Figure 5The adjustable damping assembly 9 also includes two fixed plates 906 fixedly connected to the outside of the rotating box 2. A worm gear 907 is rotatably connected to the inner side of the two fixed plates 906, and a worm wheel 908 is fixedly connected to the outer side of the internally threaded sleeve 902. The worm gear 907 and the worm wheel 908 mesh. A handle 909 is rotatably connected to the outer side of one of the fixed plates 906. The rotating end of the handle 909 is fixedly connected to the rotating end of the worm gear 907. Through the meshing structure of the worm gear 907 and the worm wheel 908, the operator can fine-tune the damping force using the handle 909, enhancing the stability of speed control. The precision reduces reliance on operator experience and further prevents the formation of internal defects in the concrete. Meanwhile, the self-locking characteristics of both the worm gear 907 and worm wheel 908 ensure stability after fine-tuning of the damping force. A first guide groove 13 is provided on the outer side of the rotating box 2, and the outer side of the connecting block 904 is slidably connected to the inner side of the first guide groove 13. The first guide groove 13 guides the movement of the connecting block 904, thereby ensuring stable contact between the rubber damping block 905 and the wear-resistant block 8, maintaining stable damping force, and thus ensuring uniform insertion and extraction speeds, avoiding localized defects in the concrete.

[0033] Example 2: A vibrator for concrete pouring of walls and columns, please refer to... Figure 1 , Figure 2 and Figure 3 Two sets of symmetrical second guide grooves 14 are provided on the outer side of the rotating box 2. Two symmetrical sliders 15 are fixedly connected to the outer side of the component box 3, and the outer side of the sliders 15 is slidably connected to the inner side of the second guide grooves 14. The cooperation of the second guide grooves 14 and the sliders 15 allows the component box 3 to move smoothly within the rotating box 2, thereby controlling the extension distance of the vibrating head 11 and further improving the practicality of the device. A top plate 16 is provided on the upper side of the rotating box 2. The bottom surface of the top plate 16 is fixedly connected to the upper surface of the component box 3. Two handles 17 are fixedly connected to the outer side of the top plate 16. The outer side of both handles 17 is covered with a rubber protective sleeve. The handles 17 provide a comfortable grip, and the outer rubber protective sleeve can also play a role in preventing slippage, making it easier for the operator to control the device stably. The vibrator is fixedly mounted on the inner side of the component box 3. The transmission flexible shaft 4 is fixedly connected to the inner side of the component box 3 through the fixed bracket. The fixed bracket fixes the transmission flexible shaft 4 to the inner side of the component box 3 to prevent displacement during vibration and ensure that the vibration energy is efficiently transmitted to the vibrating head 11, thereby improving the compaction effect and overall quality of the concrete. Two foot pedals 10 are fixedly connected to the outer side of the support frame 1. Both foot pedals 10 have anti-slip textures on their outer sides. The foot pedals 10 provide a stable standing platform for the operator. The anti-slip textures reduce the risk of slipping. When the operator steps on the foot pedals 10, the weight of the operator can be used to improve the stability of the support frame 1, ensuring stable insertion and withdrawal of the vibrator, improving the speed control accuracy, and thus avoiding problems such as concrete cavities and air bubbles.

[0034] The implementation principle of this application embodiment is as follows: When the operator uses the vibrator, first stabilizes the support frame 1 by using the foot pedal 10, and holds the handle 17. When it is necessary to adjust the insertion or withdrawal speed, the operator rotates the handle 909. At this time, the handle 909 can drive the worm 907 to rotate. At this time, the worm 907 meshes with the worm wheel 908, causing the internal thread sleeve 902 to rotate. Then, the internal thread sleeve 902 is threadedly engaged with the lead screw 903, so that the lead screw 903 and the connecting block 904 move up and down synchronously. This adjusts the contact pressure between the rubber damping block 905 and the wear-resistant block 8, thereby changing the damping force when the rotating shaft 6 rotates. At this time, the component box 3 moves up and down. At this time, the component box 3 can move stably and directionally under the guidance of the second guide groove 14 and the slider 15. At the same time, the gear 7 meshes with the rack 5 to drive the rotating shaft 6 to rotate. At this time, the contact pressure between the rubber damping block 905 and the wear-resistant block 8 can control the rotation speed of the rotating shaft 6. Thus, when the component box 3 drives the transmission flexible shaft 4 and the vibrating head 11 to perform insertion or withdrawal actions, the speed is controlled by the adjusted damping force. The vibration generated by the vibrator body 12 is transmitted to the vibrating head 11 through the transmission flexible shaft 4 to vibrate the concrete. Throughout the process, the components cooperate with each other to achieve precise control of the insertion and withdrawal speed, ensuring that the concrete is vibrated and compacted and reducing defects.
