[0024] Embodiment 2:

[0025] See also Figure 1 to Figure 8Compared with the first embodiment, the present invention is a prefabricated box girder intelligent vibrating system, and this embodiment further includes: the terminal assembly 8 includes a pressure block 81 fixedly mounted on the bottom side of the telescopic cylinder 7; the pressure block 81 is fixedly mounted on the top of the terminal shell 82 by bolts; a high-strength glass plate 83 is sealed and fixed at the end of the bottom side of the terminal shell 82; a third electromagnetic block 84 is fixedly arranged on all sides of the high-strength glass plate 83; a groove is opened around the side step of the terminal shell 82, and a claw-shaped plate 85 is rotatably arranged in the groove; an ultrasonic bubble sensor 86 with a sensing function is plugged and fixed on the side of the terminal shell 82.

[0027] The working principle of the above-mentioned intelligent vibrating system for prefabricated box beams is: First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation; Second, the operator drives the displacement gantry 1 and the biaxial adjustment member 2 through the control terminal to move the assembly frame 3 and the length control assembly 4 to the upper part where the concrete needs to be vibrated. Here, the first servo motor 42 fixed on the inner side of the assembly frame 3 drives the adjustment plate 41 and the connecting rod assembly 5 to adjust the angle, and then controls the first servo motor 42 on the side of the adjustment plate 41 to drive the first squeezing roller 44 to squeeze the connecting rod 6 and drive the displacement, so that the connecting rod 6 drives the hose and the vibrating rod outside the cable of the control console 9 to penetrate into the concrete. At this time, the position of the steel bars in the concrete is detected by the optical fiber probe 824, which is conducive to avoiding the influence of the steel mesh on the introduction of the vibrating member; Third, at the same time, the second servo motor 52 drives the adjusting disk 53 to rotate a quantitative angle and stops supplying energy to the first electromagnetic block 54 in the hole groove of the adjusting disk 53, so that the connecting rod 6 in the adjusting disk 53 slides down through the cleaning ring 57 and enters between the second squeezing rollers 56, and then drives the second squeezing rollers 56 to clamp and move the connecting rod 6 downward under the driving action of the constant speed motor 55 and engage with the top of the connecting rod 6 in the first squeezing roller 44, where the upper and lower side slots and joints in the connecting rod 6 are engaged, and the side slots and joints in the connecting rod 6 are in an open state, thereby preventing multiple groups of connecting rods 6 from detaching due to resistance when inserted into concrete, and at the same time, the first squeezing rollers 44 and the second squeezing rollers 44 are driven by the first servo motor 42 and the constant speed motor 55 respectively. The roller 56 rotates, the first squeezing roller 44 drives the upper connecting rod 6 of the two adjacent groups of connecting rods 6 to move downward, and the second squeezing roller 56 drives the lower connecting rod 6 to move upward, so that the two adjacent groups of connecting rods 6 are squeezed for a certain distance, so that the joint and the card slot are both pushed open; then the first servo motor 42 and the constant speed motor 55 drive the first squeezing roller 44 and the second squeezing roller 56 to quickly pull the two groups of connecting rods 6 apart, so that the multiple groups of connecting rods 6 can be removed, and the detachable connecting rod 6 is used to provide an equal-length linear guide for the hose on the outside of the cable of the control console 9, and at the same time, the pulse jet of the pulse nozzle 58 is used, and the concrete inside the connecting rod 6 recovered on the adjusting disk 53 is blown out with the quantitative angle adjustment of the adjusting disk 53; Fourth, the control console 9 is then used to drive the vibrating rod 821 and the end shell 82 to vibrate. Here, the softness of the material of the gel block 822 provides protection for the ultrasonic bubble sensor 86 and the optical fiber probe 824 to avoid the influence of vibration on high-precision equipment. When it is necessary to vibrate the concrete under the sleeper or the corner of the mold that is not easy to be vibrated, the second electromagnetic block 71 in the telescopic cylinder 7 is first energized to make the single-row second electromagnetic blocks 71 attract or repel each other, so that the telescopic cylinder 7 can drive the end assembly 8 to form a certain offset angle at the bottom end of the connecting rod 6, which is suitable for template angles of different specifications. Here, the claw plate 85 is driven by the magnetic field of the third electromagnetic block 84 to rotate at an angle of 45-90 degrees, thereby increasing the concrete contact area of ​​the vibrating component. Fifth, during the vibration process, the number of vibration bubbles is detected by the ultrasonic bubble sensor 86 on the outside of the terminal shell 82. Here, the remote controller 823 transmits the data of the ultrasonic bubble sensor 86 to the control console 9, and obtains the vibration bubble waveform under the calculation of the control console 9, and changes according to the waveform; when the waveform on the electronic display screen of the control console 9 is unstable, continue to vibrate until the waveform on the electronic display screen tends to be stable, and then vibrate the concrete of the next part.

[0028] The present invention provides an intelligent vibrating system for prefabricated box girders through improvements. The system adjusts a certain angle and a certain length of linear guidance of the vibration by arranging a length control component 4, a connecting rod component 5 and utilizing a detachable connecting rod 6 to the hose on the outside of the cable of the control console 9; the mutual electromagnetic action between the second electromagnetic blocks 71 is arranged so that the telescopic cylinder 7 drives the end component 8 to form a certain offset angle at the bottom end of the connecting rod 6, which is suitable for template angles of different specifications; the claw-shaped plate 85 of the end component 8 is arranged to rotate to increase the concrete contact area of ​​the vibrating component; the optical fiber probe 824 is arranged to detect the position of the steel bars in the concrete, which is beneficial to avoid the influence of the steel mesh on the introduction of the vibrating piece.
