After vibrating for the specified time, the worker pulls out the vibrator by pulling the hose.

The longitudinal bridge movement mechanism of the vibrating rod includes a cross beam 4, a guide rail 5, and a first walking unit. The information collection mechanism includes a camera 7.

[0040] Specifically, the longitudinal bridge movement mechanism of the vibrating rod includes a guide rail 5 arranged along the bridge direction, a cross beam 4, and a first walking unit provided below the cross beam 4. The cross beam 4 can be displaced along the guide rail 5 through the first walking unit. The first walking unit is specifically selected as a pulley 6. A first servo motor is provided in the pulley 6 to drive the rollers of the pulley 6, thereby realizing the displacement control of the pulley 6 on the guide rail 5. The guide rail 5 can be arranged on the box girder formwork.

[0041] Specifically, the vibrating rod telescoping mechanism The vibrating rod telescoping mechanism includes a rotating unit 3, a telescoping unit, and a vibrating rod 1 that are sequentially connected to the cross beam 4. The rotating unit 3 is arranged on the cross beam 4. The vibrating rod 1 can reach a preset vibrating depth through the telescoping unit, and the telescoping unit can adjust the inclination angle through the rotating unit 3.

[0042] Specifically, the information collection mechanism is arranged on the cross beam 4 to obtain picture information on the arrangement of top and web steel bars.

[0043] Specifically, the control mechanism is electrically connected to the longitudinal bridge movement mechanism of the vibrating rod, the vibrating rod telescoping mechanism, and the information collection mechanism respectively. The control mechanism includes a memory, a processor, etc. The processor can be selected as a processor with a mainstream architecture on the current market, such as an ARM or x86 processor, etc. The processor is electrically connected to devices that can receive instructions, such as servo motors and cameras.

[0044] The telescoping unit is a steel sleeve 2 in which multiple steel sleeves are sequentially movably nested and connected. The telescoping control principle of the steel sleeve 2 is similar to the telescoping principle of a crane boom, that is, the rope row telescoping principle. Refer to Figure 7 , and the common telescoping of multiple steel sleeves can be controlled by using one of the hydraulic rods. The control mechanism can achieve the control of elongation and contraction by controlling the input of hydraulic pressure.

[0045] The vibrating rod 1 is arranged in the innermost layer of the steel sleeve 2 and can telescope within the steel sleeve 2.

[0046] A translation slot is provided on the cross beam 4. The rotating unit 3 is arranged in the translation slot and can slide along the translation slot. The rotating unit 3 is a rotating rod. The rotating rod penetrates the translation slot, and both ends of the rotating rod are respectively connected to a steel sleeve 2.

[0047] A second traveling unit is matched with the rotating unit 3, and the second traveling unit can drive the rotating rod to slide along the translation groove. A second servo motor is provided on the second traveling unit, and the output end of the second servo motor is in transmission connection with one end of the rotating rod to provide the driving force for twisting the rotating rod. The second traveling unit can select a lead screw and a third servo motor provided on the cross beam 4 as the driving components, and the slider on the lead screw is used as the main body of the second traveling unit. The slider is connected to the outer ring of the bearing on the rotating rod, and the inner ring of the bearing is connected to the rotating rod to drive the rotating rod to translate.

[0048] An anti-vibration unit is provided between the vibrating rod 1 and the steel casing 2 to suppress the transmission of the vibration of the vibrating rod 1 along the direction of the steel casing 2. Specifically, the anti-vibration unit can be selected as damping materials such as rubber blocks.

[0049] The present invention is applicable to the vibration of the web of box girders as Figure 3 shown. The guide rail 5 can be provided on the box girder formwork. When the device is not in use, the vibrating rod 1 and the multi-layer steel casing are in a retracted state and form a 90° angle with the cross beam 4. At this time, there is a certain vertical distance between the bottom end of the vibrating rod 1 and the top plate steel bars of the box girder.

[0050] Web vibration process

[0051] Before vibration, the operator needs to select a preset vibration path at the control mechanism 8 in the present invention. Under the control of the automatic control mechanism, the device first travels along the guide rail 5 from one side of the beam to the other side driven by the trolley 6. During this period, the information camera 7 collects the layout of the top and web steel bars through image recording and compares it with the preset situation, and accordingly finely adjusts the insertion position of the vibrating rod 1.

[0052] Under the control of the control mechanism 8, the whole device moves along the guide rail 5 to the position of the web to be vibrated. After reaching the designated position, the rotating unit 3 rotates to drive the multi-layer steel casing 2 and the vibrating rod 1 to rotate to the designated inclination angle. Then the vibrating rod 1 first extends to the maximum length, and the multi-layer steel casing 2 continues to extend so that the bottom end of the vibrating rod 1 reaches the preset depth. Then the vibrating rod 1 starts to vibrate and stops vibrating after reaching the preset time.

[0053] Under the control of the control mechanism 8, the vibrating rod 1 and the multi-layer steel casing 2 contract to the shortest length at the same time. Subsequently, the whole device moves along the guide rail 5 to the next vibration position and repeats the above process.

[0054] During the process of the present invention traveling along the guide rail 5, the information acquisition mechanism will work regularly, and collect the position information of the steel bars through the image shooting of the camera 7 to correct its own parameters.

[0055] Top plate vibration process

[0056] When vibrating the top plate, under the control of the control mechanism 8, the longer vibrating rod 1 and the steel casing 2 at the web retract above the top plate reinforcement. The entire device moves along the guide rail 5 to the position of the top plate that needs to be vibrated. Then, the corresponding vibrating rod 1 at the required vibrating top plate extends and inserts into the concrete, and vibration is started after reaching the preset depth. Vibration stops after reaching the preset depth. For details, see Figure 5 .

[0057] Under the control of the control mechanism 8, the vibrating rod 1 contracts to the shortest length. Subsequently, the entire device moves along the guide rail 5 to the next vibrating position and repeats the previous process.

[0058] During the process of the present invention moving along the guide rail 5, the information acquisition mechanism will work regularly, and correct its own parameters by collecting the position information of the reinforcement through the image shooting of the camera 7.

[0059] Except for the initial vibration path setting, the above process does not require the participation of the operator, realizing the automation of the whole process, which can greatly reduce the number of construction personnel, and the vibration position, depth and time are also guaranteed.

[0060] The above description of the embodiments is to enable those of ordinary skill in the art to understand and use the invention. Obviously, those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the present invention is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the present invention should be within the protection scope of the present invention.
