Description
Technical Field
[0001] The utility model relates to the technical field of concrete vibrators, in particular to a vertical vibration monitoring device for concrete vibrators. Background Art
[0002] Concrete vibration is an essential construction link in the process of civil engineering construction. Whether it is a precast concrete structure or a cast-in-place concrete structure, the concrete poured into the formwork needs to be vibrated to eliminate the bubbles and pores inside the freshly poured concrete and ensure the density and uniformity of the concrete. The quality of the vibration construction has a direct impact on the quality and durability of the final building structure. The handheld concrete vibrator is suitable for the concrete vibration construction of various engineering structures with large quantities and wide coverage. Because it is suitable for concrete vibration in various irregular and narrow spaces, it is the most commonly used concrete vibration operation equipment. In actual operation, by vibrating the concrete Soil vibrators are inserted into the concrete to a certain depth to achieve concrete compaction. The construction standards and specifications of various countries have detailed provisions on the vibration position, depth, time, process and other indicators of concrete vibrators during vibration construction. However, the concrete vibration construction link is a hidden construction process in the construction process. The construction operation of the concrete vibrator inserted into the concrete cannot be directly observed by the naked eye. The quality of the vibration construction depends on the subjective judgment and sense of responsibility of the construction personnel. There is also a lack of relevant technical methods to monitor and evaluate the quality of the vibration construction, which increases the potential quality risk of concrete vibration construction.
[0003] When vibrating concrete with an internal vibrator, the vibrator must not touch the steel bars or formwork. However, for typical cast-in-place beams, columns, and walls, if oblique vibration is used, the vibrator can easily touch the steel bars, potentially causing them to shift. Therefore, the vibrator is generally required to be inserted naturally and vertically into the concrete. Currently, the insertion and vibration requirements are primarily based on direct observation by staff, making it impossible to accurately determine whether the angle is within the standard. Therefore, it is particularly important to improve existing monitoring devices and design a new type of vertical vibration monitoring device for concrete vibrators to address the above technical deficiencies and improve the practicality of the overall monitoring device.

[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Example:
[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:
[0024] A device for monitoring vertical vibration of a concrete vibrator includes a vibrator 1. A connecting plate 2 is provided on the outside of the vibrator 1. An RFID reader 3, a power supply module 4, and a data transmission module 5 are provided at both ends of the connecting plate 2. A connecting sleeve 6 is slidably connected to the outside of the vibrator 1. The connecting plate 2 is composed of a first composite plate 7 and a second composite plate 8. The first composite plate 7 and the second composite plate 8 are connected to the connecting sleeve 6 via a connecting assembly 9. A connecting shell 10 is provided on the end of the vibrator 1 away from the connecting sleeve 6.
[0025] The connecting assembly 9 is used to connect the connecting plate 2 with the connecting sleeve 6, and the connecting assembly 9 consists of a fixed block 11, a movable block 12 and a mounting block 13. The two groups of fixed blocks 11 are both located at one end of the first combination plate 7 close to the second combination plate 8, the two groups of movable blocks 12 are both slidably connected to the inside of the fixed block 11, and the two groups of mounting blocks 13 are both located at one end of the second combination plate 8 close to the first combination plate 7.
[0026] Furthermore, a clamping block 14 is provided on the outer side of the movable block 12, and a mounting groove is provided inside the mounting block 13. The internal structure size of the mounting groove is designed to correspond to the external structure size of the clamping block 14. The mounting block 13 is connected to the clamping block 14 through the mounting groove. By connecting the clamping block 14 to the mounting groove, the clamping block 14 can be connected to the mounting block 13, thereby enabling the fixed block 11 to be connected to the mounting block 13.
[0027] Among them, a rotating disk 15 is rotatably connected inside the fixed block 11 and located on the outside of the two groups of moving blocks 12. Both ends of the rotating disk 15 are rotatably connected to rotating rods 16. The end of the rotating rod 16 away from the rotating disk 15 is rotatably connected to the moving block 12. Rotating the rotating disk 15 drives the rotating rod 16 to move, so that the moving block 12 can move, driving the clamping block 14 to move.
[0028] Secondly, a fixed plate 17 is provided on the outer side of the rotating disk 15, and two sets of sliding rods 18 are provided at one end of the fixed plate 17 close to the moving block 12. Two sets of sliding grooves are opened inside the moving block 12, and the moving block 12 is connected to the sliding rods 18 through the sliding grooves. The sliding grooves are connected to the sliding rods 18 so that the moving block 12 can be slidably connected to the sliding rods 18. When the moving block 12 is displaced, it can be guided by the sliding rods 18 to prevent the moving block 12 from offsetting.
[0029] Furthermore, a worm gear 19 is fixedly connected to one end of the rotating disk 15 away from the fixed plate 17 , and a worm 20 is meshedly connected to the outer side of the worm gear 19 . Rotating the worm 20 drives the worm gear 19 to rotate, so that the rotating disk 15 can rotate.
[0030] Furthermore, a connecting groove 21 is provided inside the first combination plate 7 and the second combination plate 8, and the first combination plate 7 and the second combination plate 8 are connected to the connecting sleeve 6 through the connecting groove 21. A fixing rod 22 is provided inside the connecting groove 21, and the connecting groove 21 is connected to the connecting sleeve 6 through the fixing rod 22. The connecting groove 21 is connected to the connecting sleeve 6, so that the first combination plate 7 and the second combination plate 8 can be connected to the connecting sleeve 6. When the connecting groove 21 is connected to the connecting sleeve 6, the stability of the connection between the connecting groove 21 and the connecting sleeve 6 can be increased by the fixing rod 22.
[0031] Furthermore, the connecting shell 10 is internally rotatably connected to a drive screw 23, which is threadedly connected to the connecting sleeve 6, and the outer side of the drive screw 23 is fixedly connected to the drive end of the drive motor. When the drive motor is started, the drive screw 23 is driven to rotate, so that the connecting sleeve 6 can be displaced, and the connecting plate 2 is driven to be displaced. Even if the vibrating rod 1 is inserted into deeper concrete, the RFID reader 3, the power supply module 4 and the data transmission module 5 can still remain outside the concrete and work normally, avoiding the problem of wireless signal interruption caused by the sensor being immersed in the concrete. Through RFID technology, the depth of the vibrating rod 1 inserted into the concrete can be measured in real time and accurately to ensure that the vibration depth and vibration process meet the requirements of national construction specifications. A microcontroller and an angle sensor are provided inside the connecting plate 2 to judge the angle of the vibrating rod 1. The microcontroller includes but is not limited to an Arduino microcontroller, such as the Arduino microcontroller with model Mega2560; the angle sensor includes but is not limited to a six-axis angle gyroscope sensor, such as the sensor with model MPU6050.
[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, the two groups of connecting grooves 21 are connected to the connecting sleeve 6, so that the first combination plate 7 and the second combination plate 8 can be connected to the connecting sleeve 6, and the rotating worm 20 drives the worm wheel 19 to rotate, so that the rotating disk 15 can rotate, and drives the rotating rod 16 to displace, so that the moving block 12 can be displaced, and drives the clamping block 14 to displace, and connects the clamping block 14 to the mounting groove, so that the clamping block 14 can be connected to the mounting block 13, so that the fixed block 11 can be connected to the mounting block 13, and the connecting plate 2 is connected to the connecting sleeve 6. The self-locking property of the worm wheel 19 and the worm 20 can prevent the clamping block 14 from deviating inside the mounting groove, and the drive is started. The motor drives the driving screw 23 to rotate, so that the connecting sleeve 6 can be displaced, and the connecting plate 2 can be displaced. Even if the vibrating rod 1 is inserted into the deeper concrete, the RFID reader 3, the power supply module 4 and the data transmission module 5 can still remain outside the concrete and work normally, avoiding the problem of wireless signal interruption caused by the sensor being immersed in the concrete. Through RFID technology, the depth of the vibrating rod 1 inserted into the concrete can be measured accurately and in real time to ensure that the vibration depth and vibration process meet the requirements of national construction specifications. A microcontroller and an angle sensor are provided inside the connecting plate 2 to judge the angle of the vibrating rod 1. Compared with the existing monitoring device, the utility model can improve the overall practicality of the monitoring device through design.
