Description

Technical Field

[0001] This utility model relates to the field of vibratory bar technology, and specifically discloses a vibratory bar for concrete pouring. Background Technology

[0002] A concrete vibrator is a widely used tool in engineering construction, primarily used to uniformly compact the interior of concrete, ensuring a dense bond and eliminating honeycomb and pitting defects, thereby increasing the concrete's strength. It is suitable for the construction of various concrete structures, such as bridges, tunnels, water conservancy projects, airports, docks, and buildings. In the field of concrete construction, the vibrator is an indispensable tool, playing a crucial role in ensuring concrete construction quality and improving project efficiency.

[0003] Based on the above, the inventors of this application have discovered the following problems in the prior art: the vibration force of the current vibrator is fixed, and it can only output vibration of a single intensity. For concrete of different thicknesses, such as the thick layer of concrete piled at the bottom and the thin layer of concrete at the top in the segmented pouring of a sloping roof, the vibration intensity cannot be flexibly adjusted. The thick layer of concrete is difficult to compact due to insufficient vibration force, and is prone to honeycomb and pitting. The thin layer of concrete is prone to segregation and leakage due to excessive vibration force, which affects the molding quality and thus reduces the practicality of the vibrator.

[0004] Therefore, in view of this, the applicant has studied and improved the existing structure and its shortcomings, and provided a vibrator for concrete pouring, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a vibratory bar for concrete pouring to solve the problems mentioned in the background art.

[0006] To solve the above problems, the technical solution proposed by this utility model is as follows:

[0007] A vibratory bar for concrete pouring includes a connecting assembly and an adjusting assembly. The adjusting assembly is positioned above the connecting assembly and is used to adjust the vibration force according to the thickness of the concrete being poured. The connecting assembly is used to connect two vibratory bars to increase their length. The adjusting assembly includes a bar body with a square cavity inside. A dual-axis motor is installed at the center of the bar body. Each of the two output ends of the dual-axis motor has a first locking block. A servo motor is installed at both the bottom and top of the bar body, and a second locking block is installed at the output ends of both servo motors. A first lifting seat and a second lifting seat are slidably arranged above and below the dual-axis motors inside the bar body, respectively. Rotating rods are rotatably connected inside both the first and second lifting seats. A first locking groove is opened at the opposite end of each pair of rotating rods, and a second locking groove is opened at the opposite end of each pair of rotating rods. A pair of first locking blocks are located inside the pair of first locking grooves, and a pair of second locking blocks are located inside the pair of second locking grooves.

[0008] Furthermore, an eccentric wheel is fitted around the outside of each pair of rotating rods.

[0009] The beneficial effects of adopting the above-mentioned further scheme are as follows: the eccentric wheel is the core component of the vibrator that generates vibration. When the rotating rod drives the eccentric wheel to rotate, the eccentric wheel will generate centrifugal force due to the shift of the center of gravity, which in turn drives the rod to generate high-frequency vibration. When the two eccentric wheels rotate synchronously in the same direction, the centrifugal force is superimposed, and the vibration force is enhanced, which is suitable for vibrating thick concrete. When the two eccentric wheels rotate in opposite directions, the centrifugal force is partially canceled, and the vibration force is weakened, which is suitable for thin concrete and is applicable to the vibration intensity requirements of different pouring scenarios.

[0010] Furthermore, the cross-sections of both the first and second card blocks are cross-shaped, the outer wall of the first card block slides into the inner wall of the first card slot, and the outer wall of the second card block slides into the inner wall of the second card slot.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the "+" shaped structure can stably transmit torque, ensuring that the power of the dual-axis motor or servo motor can be transmitted to the rotating rod through the first or second locking block, driving the eccentric wheel to rotate and generate vibration; the sliding fit allows the rotating rod to move in the axial direction. When the first or second lifting seat drives the rotating rod to move closer to the servo motor, the first locking block can separate from the first locking slot, allowing the second locking block to insert into the second locking slot, thus converting the pair of eccentric blocks that originally rotated in the same direction into rotating in opposite directions. Then, when the first or second lifting seat drives the rotating rod to move closer to the dual-axis motor, the second locking block can separate from the second locking slot, allowing the first locking block to insert into the first locking slot, thus converting the pair of eccentric blocks that originally rotated in opposite directions into rotating in the same direction.

[0012] Furthermore, the rod body has first square grooves on both sides of the inner wall above the dual-axis motor. A first electric slide rail is installed inside each pair of first square grooves. A first electric slider is slidably connected to the outside of each pair of first electric slide rails. One end of each pair of first electric sliders is fixedly connected to the outer wall of the first lifting seat. The rod body has second square grooves on both sides of the inner wall below the dual-axis motor. A second electric slide rail is installed inside each pair of second square grooves. A second electric slider is slidably connected to the outside of each pair of second electric slide rails. One end of each pair of second electric sliders is fixedly connected to the outer wall of the second lifting seat.

[0013] The beneficial effects of adopting the above-mentioned further scheme are: the first electric slide rail drives the first lifting seat to move, and the second electric slide rail drives the second lifting seat to move.

[0014] Furthermore, the two first electric slide rails drive the first electric sliders at the same speed and in the same direction, and the two second electric slide rails drive the second electric sliders at the same speed and in the same direction. The first electric slide rails drive the first electric sliders at the same speed, and the second electric slide rails drive the second electric sliders at opposite directions.

[0015] The beneficial effects of adopting the above-mentioned further scheme are as follows: Since the moving speed and moving direction of the first electric slider driven by the two first electric slide rails are the same, the first lifting seat moves stably up or down; Since the moving speed and moving direction of the second electric slider driven by the two second electric slide rails are the same, the second lifting seat moves stably up or down; Since the moving speed of the first electric slider driven by the first electric slide rail and the moving direction of the second electric slider driven by the second electric slide rail are the same and the moving directions are opposite, the first lifting seat and the second lifting seat move up and down synchronously, so that the two eccentric wheels are always symmetrically distributed around the dual-axis motor.

[0016] Furthermore, the two output ends of the dual-axis motor have the same rotation speed and the same direction of rotation, and the output ends of the two servo motors have the same rotation speed but opposite directions of rotation.

[0017] The beneficial effects of adopting the above-mentioned further scheme are as follows: When the two rotating rods are driven by the dual-axis motor at the same speed and in the same direction, the centrifugal forces of the two eccentric wheels are in the same direction, the resultant force is the largest, and strong vibration can be generated. This is suitable for thick concrete layers, such as the concrete piled in the lower part of the segmented pouring of sloping roofs, and can effectively vibrate and compact it. When the two servo motors drive the rotating rods at the same speed and in opposite directions, the centrifugal forces of the two eccentric wheels are in opposite directions. After partial cancellation, the resultant force is reduced, generating weak vibration. This is suitable for thin concrete layers, such as the thin layer on the upper part of sloping roofs, and can avoid concrete segregation or leakage caused by excessive vibration. By switching the operation of the dual-axis motor and the servo motor, the intensity of vibration can be quickly switched to meet the vibration needs of concrete of different thicknesses in the same construction scenario.

[0018] Furthermore, mounting slots are provided on the rod body near the dual-axis motor and a pair of servo motors, and heat dissipation fins are installed inside the mounting slots.

[0019] The beneficial effects of adopting the above-mentioned further solutions are: when dual-axis motors and servo motors operate at high frequencies, they generate a large amount of heat. By increasing the contact area with the air, the heat dissipation fins can quickly transfer the heat generated by the motor to the air, thus accelerating heat dissipation.

[0020] Furthermore, the connecting assembly includes a connecting seat, the upper end and the bottom end of which are provided with grooves, the inner wall of one of the grooves being in contact with the outer wall of the bottom end of the rod, the upper end and the bottom end of the connecting seat are respectively provided with a first threaded groove and a second threaded groove, the first threaded groove being threadedly connected to a threaded post, the threaded post being fixedly connected to the bottom end of the rod at the end away from the second threaded groove.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: the connecting seat enables the rapid splicing of two vibratory rods through threaded connection, and the rod length can be flexibly increased according to the pouring depth, such as deep beams, thick slabs or high-slope roofs, without the need to replace the entire equipment, thus improving versatility; the rod length is increased by inserting the threaded post at one end of the two rods into the first and second threaded grooves in the connecting seat and rotating them; the threaded post and the first threaded groove are firmly connected and can withstand the high-frequency vibration during tamping, preventing loosening at the splice.

[0022] Compared with the prior art, the advantages and beneficial effects of this utility model are:

[0023] This invention relates to a vibrator for concrete pouring. Because the first locking block is placed inside the first locking slot, and a dual-axis motor is used, when the motor is working, it drives two rotating rods to rotate in the first and second lifting seats respectively. This causes the two eccentric wheels to rotate synchronously in the same direction, resulting in superimposed centrifugal forces and enhanced vibration, making it suitable for vibrating thick concrete layers. A first electric slide rail drives the first lifting seat to move, and a second electric slide rail drives the second lifting seat to move. When the first or second lifting seat moves the rotating rods towards the servo motor, the first locking block can separate from the first locking slot, allowing the second locking block to insert into the second locking slot. Then, a pair of servo motors are simultaneously activated, driving the two rotating rods to rotate in the first and second lifting seats respectively. When the two eccentric wheels rotate in opposite directions, the centrifugal forces partially cancel each other out, reducing the vibration force, making it suitable for thin concrete layers and applicable to different pouring scenarios with varying vibration intensity requirements. By switching between the dual-axis motor and the servo motor, the intensity of the vibration can be quickly switched to meet the vibration needs of concrete of different thicknesses in the same construction scenario.

Detailed Implementation

[0030] The applicant will now provide a clear and complete description of the technical solutions in the embodiments of this utility model with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example:

[0032] Please see Figures 1-5A vibratory bar for concrete pouring includes a connecting assembly 1 and an adjusting assembly 2. The adjusting assembly 2 is positioned above the connecting assembly 1 and is used to adjust the vibration force according to the thickness of the concrete being poured. The connecting assembly 1 is used to connect two vibratory bars to increase their length. The adjusting assembly 2 includes a bar body 21, with a square cavity inside the bar body 21. A dual-axis motor 22 is installed at the center of the bar body 21. First locking blocks 23 are installed at both output ends of the dual-axis motor 22. Servo motors 24 are installed at the bottom and top of the bar body 21, and the output ends of the two servo motors 24 are... The rod body 21 is equipped with a second locking block 25. Inside the rod body 21, a first lifting seat 26 and a second lifting seat 27 are slidably mounted above and below the dual-axis motor 22, respectively. Rotating rods 28 are rotatably connected inside both the first and second lifting seats 26 and 27. A first locking groove 210 is formed at the opposite end of each pair of rotating rods 28, and a second locking groove 211 is formed at the opposite end of each pair of rotating rods 28. A pair of first locking blocks 23 are located inside the pair of first locking grooves 210, and a pair of second locking blocks 25 are located inside the pair of second locking grooves 211. A locking mechanism is fitted over the outside of each pair of rotating rods 28. With an eccentric wheel 29, and since the first locking block 23 is placed inside the first locking slot 210, a dual-axis motor 22 is provided. When the motor is working, it drives two rotating rods 28 to rotate in the first lifting seat 26 and the second lifting seat 27 respectively, so that the two eccentric wheels 29 rotate synchronously in the same direction. The centrifugal force is superimposed, and the vibration force is enhanced, which is suitable for vibrating thick concrete. The first electric slide rail 212 drives the first lifting seat 26 to move, and the second electric slide rail 213 drives the second lifting seat 27 to move. When the first lifting seat 26 or the second lifting seat 27 drives the rotating rod 28 to move towards the direction close to the servo motor 24, The first locking block 23 can be separated from the first locking slot 210, allowing the second locking block 25 to be inserted into the second locking slot 211. Then, a pair of servo motors 24 are started simultaneously, driving the two rotating rods 28 to rotate in the first lifting seat 26 and the second lifting seat 27 respectively. When the two eccentric wheels 29 rotate in opposite directions, the centrifugal force is partially canceled, and the vibration force is weakened, which is suitable for thin-layer concrete and applicable to the vibration intensity requirements of different pouring scenarios. By switching the operation of the dual-axis motor 22 and the servo motor 24, the intensity of vibration can be quickly switched to meet the vibration requirements of concrete of different thicknesses in the same construction scenario.

[0033] Furthermore, the cross-sections of the first locking block 23 and the second locking block 25 are both cross-shaped. The outer wall of the first locking block 23 slides in conjunction with the inner wall of the first locking groove 210, and the outer wall of the second locking block 25 slides in conjunction with the inner wall of the second locking groove 211. The rod body 21 has first square grooves on both sides of its inner wall above the dual-axis motor 22. A first electric slide rail 212 is installed inside each pair of first square grooves, and a first electric slider is slidably connected to the outside of each pair of first electric slide rails 212. One end of each pair of first electric sliders is fixedly connected to the outer wall of the first lifting seat 26. The rod body 21 has a first electric sliding block on its inner wall below the dual-axis motor 22. Both sides are provided with second square slots. A second electric slide rail 213 is installed inside each pair of second square slots. A second electric slider is slidably connected to the outside of each pair of second electric slide rails 213. One end of each pair of second electric sliders is fixedly connected to the outer wall of the second lifting seat 27. The two first electric slide rails 212 drive the first electric sliders at the same speed and in the same direction. The two second electric slide rails 213 drive the second electric sliders at the same speed and in the same direction. The first electric slide rail 212 drives the first electric slider, and the second electric slide rail 213 drives the second electric slider at the same speed but in opposite directions. The two outputs of the dual-axis motor 22 have the same speed and the same direction of rotation. The outputs of the two servo motors 24 have the same speed but opposite directions of rotation. Mounting slots are provided on the rod body 21 near the dual-axis motor 22 and the pair of servo motors 24. Heat dissipation fins 215 are installed inside several mounting slots. The cross-shaped structure can stably transmit torque, ensuring that the power of the dual-axis motor 22 or the servo motor 24 can be transmitted to the rotating rod 28 through the first locking block 23 or the second locking block 25, driving the eccentric wheel 29 to rotate and generate vibration. The first electric slide rail 212 drives the first lifting seat 26 to move, and the second electric slide rail 213 drives the second... When the lifting seat 27 moves, and the first lifting seat 26 or the second lifting seat 27 drives the rotating rod 28 to move towards the direction of the servo motor 24, the first locking block 23 can separate from the first locking slot 210, so that the second locking block 25 can be inserted into the second locking slot 211, causing the pair of eccentric blocks that originally rotated in the same direction to rotate in opposite directions. Then, when the first lifting seat 26 or the second lifting seat 27 drives the rotating rod 28 to move towards the direction of the dual-axis motor 22, the second locking block 25 can separate from the second locking slot 211, so that the first locking block 23 can be inserted into the first locking slot 210, causing the pair of eccentric blocks that originally rotated in opposite directions to rotate in the same direction.

[0034] Furthermore, the connecting component 1 includes a connecting seat 11, with grooves 12 at both the upper and lower ends. The inner wall of one of the grooves 12 fits against the outer wall of the bottom end of the rod 21. The upper and lower ends of the connecting seat 11 are respectively provided with a first threaded groove 13 and a second threaded groove 14. A threaded post 214 is threadedly connected inside the first threaded groove 13. The end of the threaded post 214 away from the second threaded groove 14 is fixedly connected to the bottom end of the rod 21. The connecting seat 11 enables the rapid splicing of two vibrating rods through threaded connection. The length of the rod 21 can be flexibly increased according to the pouring depth, such as deep beams, thick slabs, or high-slope roofs, without replacing the entire equipment, thus improving versatility. The length of the rod 21 can be increased by inserting the threaded post 214 at one end of the two rods 21 into the first threaded groove 13 and the second threaded groove 14 in the connecting seat 11 and rotating it. The threaded post 214 and the first threaded groove 13 are firmly connected and can withstand the high-frequency vibration during tamping, preventing loosening at the splice.

[0035] Specifically, the working principle of this utility model for a concrete pouring vibrator is as follows: During use, the "+" shaped structure can stably transmit torque, ensuring that the power of the dual-axis motor 22 or servo motor 24 can be transmitted to the rotating rod 28 through the first locking block 23 or the second locking block 25, driving the eccentric wheel 29 to rotate and generate vibration. Since the first locking block 23 is placed inside the first locking slot 210, by setting the dual-axis motor 22, when it works, it drives the two rotating rods 28 to rotate in the first lifting seat 26 and the second lifting seat 27 respectively, so that the two eccentric wheels 29 rotate synchronously in the same direction. The centrifugal force of the two eccentric wheels 29 is in the same direction, resulting in the maximum resultant force, which can generate strong vibration. This is suitable for thick concrete layers, such as the concrete piled in the lower part of a sloping roof segmented pouring, and can effectively vibrate and compact it. The first electric slide rail 212 drives the first lifting seat 26 to move, and the second electric slide rail... 213 drives the second lifting seat 27 to move. When the first lifting seat 26 or the second lifting seat 27 drives the rotating rod 28 to move towards the servo motor 24, the first locking block 23 can separate from the first locking slot 210, so that the second locking block 25 can be inserted into the second locking slot 211. Then, a pair of servo motors 24 are started at the same time, driving the two rotating rods 28 to rotate in the first lifting seat 26 and the second lifting seat 27 respectively. When the two eccentric wheels 29 rotate in opposite directions, the centrifugal forces of the two eccentric wheels 29 are opposite in direction. After partial cancellation, the resultant force is reduced, generating weak vibration. This is suitable for thin-layer concrete, such as the thin layer on the upper part of a sloping roof, and can avoid concrete segregation or grout leakage caused by excessive vibration. By switching the operation of the dual-axis motor 22 and the servo motor 24, the intensity of vibration can be quickly switched to meet the vibration needs of concrete of different thicknesses in the same construction scenario.
