[0035] The following is combined with Figure 1-2 This application is described in further detail.

[0036] The embodiment of the present application discloses a vibration auxiliary device applied to a bridge pier.

[0037] Reference Figure 1The vibration auxiliary device applied to the bridge pier includes a guide mechanism 2 and a recording component 3. The guide mechanism 2 is used to guide and insert the vibration device 1 into the bottom layer of the bridge formwork. The vibration device 1 is a device used for vibrating concrete in the prior art, such as a vibrator, so it is not described here. The recording component 3 is used to record the vibration time and observe the vibration situation. The guide mechanism 2 includes a hose 21, a clamp 22 and a fixing plate 23.

[0038] Since most bridge piers are of special shapes, it is inconvenient to lower the vibrating device 1. In the present application, there are multiple hoses 21 that can be connected to each other. The hose 21 can change its shape according to the special-shaped pier, which is convenient for guiding the vibrating device 1 to enter. The hose 21 should be installed in advance. After the hose 21 is connected and laid out in advance, the vibrating device 1 is placed in order to prevent the vibrating device 1 from being blocked by messy steel bars, and to prevent the vibrating device 1 from deviating from the position where it needs to be vibrated when it is lowered, and to facilitate the vibrating device 1 to be directly inserted into the concrete bottom layer for vibrating work.

[0039] A plurality of connected hoses 21 form a group, and there is at least one group of hoses 21. The plurality of groups of hoses 21 are arranged in an array, so that the vibration range can cover the entire concrete as much as possible, thereby improving the vibration quality. A clamp 22 is installed at the connection between each two sections of hoses 21 and is used to fix the hoses 21; there are a plurality of fixing plates 23, and two of them form a group. The fixing plates 23 are horizontally mounted on the template, and the two fixing plates 23 of the same group are parallel. The end of the hose 21 is located between the two fixing plates 23 and passes through from top to bottom. The side wall of the upper end of the hose 21 contacts the two fixing plates 23. The hose 21 is fixed to the fixing plates 23 by a steel clamp, and the vibrating device 1 is placed on the fixing plates 23 for use.

[0040] Reference Figure 1 The recording component 3 includes a timer 31, a camera 32 and a display 33. The camera 32 is electrically connected to the display 33 and the controller 4. The timer 31 can be an electronic watch and is installed on the fixing plate 23 to facilitate observation and recording of the actual vibration time. The camera 32 can be a night vision camera 32 and is installed on the bottom clamp 22. The camera 32 is always located above the poured concrete, with the camera end facing downward. Concrete is poured in layers. Whenever a layer of concrete is poured and vibrated, a section of the hose 21 is retracted, and the hose 21 of this group is lifted upward accordingly, and the camera 32 is lifted upward at the same time. The position of the camera 32 is raised, so it is always located above the poured concrete.

[0041] The timer 31 is convenient for controlling the actual vibration time and the thickness of the layered pouring, and can record the time of each vibration so that the average vibration time and the maximum vibration time can be more reasonably evaluated. The camera 32 can capture the image information of the concrete surface and transmit it back to the display 33, which is more convenient to judge whether it is over-vibration or missed vibration and reduce the possibility of over-vibration and missed vibration, thereby improving the quality of concrete vibration.

[0042] Reference Figure 2 , further comprising a controller 4, the vibrating device 1 and the display 33 are electrically connected to the controller 4 respectively, wherein the control system of the vibrating device 1 is electrically connected to the controller 4 and is configured as follows:

[0043] Get image information; the image information is captured by the camera.

[0044] Recognize the image to obtain the soil surface information of the concrete;

[0045] Get as standard Figure 1 Image information of concrete over-vibration or under-vibration; among which the standard Figure 1 The images of concrete over-vibration and under-vibration can be searched in the database and set as the standard for comparison. Figure 1 .

[0046] Real-time soil surface information and standards Figure 1 Make a comparison and determine whether there is over-vibration or missed vibration;

[0047] If there is over-vibration, the vibration device 1 is instructed to reduce the vibration amplitude or shorten the vibration time;

[0048] If there is currently leakage vibration, check and determine whether the working state of the vibrating device 1 meets the preset abnormal conditions, where the abnormal conditions may be detection that the vibrating device 1 is not in a working state or feedback of a machine failure; if the abnormal conditions are met, output a preset alarm message; wherein the working state includes the operating state, such as the machine is not running or the operating speed is significantly different from the preset speed.

[0049] The camera 32 is installed to facilitate observation of the specific conditions of the concrete surface. By comparing the image information of known concrete over-vibration or under-vibration, it can be determined whether the concrete has over-vibration or under-vibration problems, so that the next step of work can be carried out according to different situations.

[0050] Reference Figure 1, and also includes a tube collecting mechanism 5, which includes a long rope and a rope winding assembly 51 for winding up the long rope, one end of the long rope is connected to the rope winding assembly 51 and is stored around the rope winding assembly 51, and circular rings are symmetrically arranged on the side wall of the hose 21 with the center of the pipe mouth as the center, the long rope is tied to the circular ring of the hose 21 at the bottom and passes through the circular ring of each hose 21 at the upper end, so that the long rope can be confined in the circular ring so that it is close to the hose 21 without deviation, thereby reducing the situation where the long rope is released too long and the bottom end droops, and can also better help the hose 21 to be retracted.

[0051] The rope winding assembly 51 includes a drum 511, a base 512 and a motor 513. The drum 511 is cylindrical and has a rotating shaft fixed inside. Both ends of the rotating shaft are fixed to the base 512. The base 512 is located on the fixed plate 23, and a motor 513 is installed on the side of the base 512. The motor 513 is fixed to the base 512 through a fixed bracket. The output shaft of the motor 513 is fixed to the rotating shaft of the drum 511. The motor 513 can be a servo motor, which can drive the drum 511 to rotate to collect and release the rope.

[0052] Reference Figure 2 , the motor 513 is electrically connected to the controller 4, and the controller 4 is configured as follows:

[0053] Get as standard Figure 2 The image information of the concrete returning to the top may be the image information of the concrete returning to the top obtained before, or the image information of the concrete returning to the top retrieved from the database, wherein the concrete soil surface rises and lifts up the hose when returning to the top.

[0054] Combine real-time soil surface information with standard Figure 2 Compare and determine whether there is concrete back-up; the judgment of back-up can be to observe whether the position of the hose moves up or whether the end of the hose is stained with concrete.

[0055] If the concrete returns to the top of the hose 21, the rope winding assembly 51 starts to work;

[0056] The specification information of the hose 21 is obtained, including the length and the diameter or radius of the hose 21 .

[0057] The total length of the disassembled hose 21 is evaluated according to the working parameters of the rope winding assembly 51, and the thickness to be vibrated is calculated; the total length of the disassembled hose 21 can be calculated by multiplying the preset rotation speed of the rope winding assembly 51 by its working time.

[0058] When the concrete returns to the top of the hose 21, the hose 21 is retracted, which can facilitate better control and recording of the vibration time. After image recognition and comparison of the image information when the concrete returns to the top, it can be determined whether the concrete returns to the top of the hose 21 at this time. If it returns to the top of the hose 21, the rope winding assembly 51 can be controlled to start working, wind up the long rope to raise the position of the hose 21, and then retract the top section of the hose 21.

[0059] Reference Figure 1 A groove is dug on the side wall of the hose 21, and a laser distance sensor 211 is arranged in the groove. A rubber block is fixed on the back of the laser distance sensor 211. The rubber block is semicircular, and the round end is used to be inserted into the groove. The notch of the groove extends inward and only leaves a small hole for the rubber block to be inserted. There can be multiple grooves, which are distributed around the hose 21, so that the most suitable groove is selected to fix the laser distance sensor 211. The detection end of the inserted laser distance sensor 211 extends toward the adjacent group of hoses 21 located on the side, so that the measured data is more accurate.

[0060] Reference Figure 2 , the laser distance measuring sensor 211 is electrically connected to the controller 4, and the controller 4 is configured as follows:

[0061] Obtaining distance information fed back by the laser ranging sensor 211;

[0062] The radius of vibration of the vibrating device 1 is determined according to the distance information; the radius of vibration should be half of the distance between the two groups of hoses 21, so that full coverage vibration can be achieved and the vibration intensity will not be too high.

[0063] The hose 21 is provided with a limit assembly, which includes a folding block 1 and a folding block 2. The folding block 1 and the folding block 2 are respectively located at the two ends of the hose 21, and the folding block 1 is formed by the hose 21 being turned outward, and the bottom end of the folding block 1 first extends outward, and then bends upward; the folding block 2 is formed by the hose 21 being turned inward, and the upper end of the folding block 2 first extends outward, then bends inward, and finally bends downward to form a buckle structure. The folding block 1 and the folding block 2 of the two upper and lower adjacent hoses 21 are buckled and mutually conflicted, and the two upper and lower adjacent hoses 21 can be further fixed by the folding block 1 and the folding block 2.

[0064] Reference Figure 2 , an alarm 311 is installed on the timer 31, and the timer 31 and the alarm 311 are electrically connected to the controller 4 respectively. The configuration of the controller 4 is as follows:

[0065] Set the preset vibration time; the vibration time is determined according to the specific conditions of the concrete, for example: the preset maximum vibration time for each time is 30s.

[0066] If the vibrating device 1 is working, the time is counted;

[0067] If the vibration of the vibrating device 1 is completed, the time of this vibration is recorded; wherein the vibration completion signal can be obtained by feedback from the control system of the vibrating device.

[0068] If the duration of the vibration reaches the preset vibration time, the alarm 311 is set to sound. The alarm 311 can remind the user to stop the vibration in time, thereby effectively preventing over-vibration.
