[0052] like Figure 1-Figure 9As shown, an intelligent vibration reduction type vibrating device for prefabricated box girder concrete of high-speed railway includes an overhead crane 100, a total station 140 is connected to the side of the overhead crane 100, a truss 210 is connected to the bottom, a hydraulic rod 220 is connected to the middle of the truss 210, a mounting seat 230 is connected to the bottom end of the hydraulic rod 220, a mechanical arm 240 and a prism 260 are connected to the lower part of the mounting seat 230, and a vibrating rod 250 is connected to the mechanical arm 240.
[0053] The working mechanism of the intelligent vibration reduction type vibrating equipment for high-speed railway prefabricated box beam concrete provided in this embodiment is as follows:
[0054] The crane 100 is a mobile lifting device for the prefabricated beam site. The total station 140 has a self-driving motor. When selecting the total station 140, it is not required to have too high detection accuracy, range, and safety protection level. The selection is mainly based on the equipment measurement stability and cost performance. The total station 140 system has an open port to facilitate secondary software development. The truss 210 is used to fix the hydraulic rod 220. The truss 210 is driven by the crane 100 to move horizontally, and the mechanical arm 240 is driven by the hydraulic rod 220 to move vertically. The crane 100 and the hydraulic rod 220 drive the mechanical arm 240 together. The mechanical arm 240 drives the vibrating rod 250 to move to the working range. After the mechanical arm 240 is unfolded, the working position of the vibrating rod 250 is accurately adjusted. The total station 140 cooperates with the prism 260 to act on the overhead travelling crane 100 and the hydraulic rod 220 to realize the automatic movement of the position of the mechanical arm 240. An angle sensor is installed on the mechanical arm 240 to detect the angle of the mechanical arm 240 and to collect arm length data to accurately realize the positioning of the vibrating rod 250. The vibrating rod 250 on the mechanical arm 240, the total station 140 and various sensors cooperate to realize concrete vibration and detection operations.
[0055] Among the optional methods of this embodiment, the more preferred ones are:
[0056] The overhead travelling crane 100 includes a single beam 110 , on which a moving seat 120 is mounted. An L-shaped frame 130 is connected to the side of the moving seat 120 . A total station 140 is connected to the lower part of the horizontal portion of the L-shaped frame 130 . A truss 210 is connected to the lower part of the moving seat 120 .
[0057] The vibrating mechanism 200 is composed of a truss 210, a hydraulic rod 220, a mounting seat 230, a mechanical arm 240, a vibrating rod 250 and a prism 260. The moving seat 120 moves on the single beam 110, thereby driving the truss 210 to move. The L-shaped frame 130 is connected to the side of the moving seat 120, and the lower part of the horizontal section of the L-shaped frame 130 is connected to the metal plate. The total station 140 is installed on the lower surface of the metal plate, and the truss 210 is connected to the lower part of the moving seat 120, so that the moving seat 120 can drive the total station 140 and the truss 210 to move together.
[0058] Regarding the structure of the shock absorbing mechanism 300, specifically:
[0059] A shock-absorbing mechanism 300 is arranged between the truss 210 and the movable seat 120, and the shock-absorbing mechanism 300 includes a C-shaped frame 310. The truss 210 is connected to the lower part of the C-shaped frame 310, and the C-shaped frame 310 is clamped on the movable seat 120. A shock-absorbing airbag 320 and a rubber block 330 are connected between the C-shaped frame 310 and the movable seat 120, and the shock-absorbing airbag 320 is located at the upper part of the rubber block 330.
[0060] Protrusions are provided on both sides of the movable seat 120, and the C-shaped frame 310 is stuck on the protrusions. The upper part of the C-shaped frame 310 is connected to the movable seat 120 through the shock-absorbing airbag 320 between the protrusions, and the lower part is connected to the movable seat 120 through the rubber block 330. When the vibrating rod 250 generates vibration during operation, the vibration is transmitted to the C-shaped frame 310, and the shock-absorbing airbag 320 and the rubber block 330 are used to reduce the vibration of the truss 210, so that the vibration of the movable seat 120 is reduced, thereby ensuring the relative position between the movable seat 120 and the single beam 110, and further ensuring that the coordinates of the vibrating rod 250 are not affected by the vibration and are greatly offset.
[0061] Among the optional methods of this embodiment, the more preferred ones are:
[0062] The shock absorbing mechanism 300 further includes a pipe 350 , which is connected to the shock absorbing airbag 320 . A first piston rod 360 is slidably connected in the pipe 350 . A tension spring 380 is connected between the bottom of the first piston rod 360 and the shock absorbing airbag 320 .
[0063] When the vibrating rod 250 vibrates vertically, it moves up and down so that it switches between an overweight state and a weightless state. When the vibrating rod 250 is in an overweight state, a downward force is applied to the truss 210, so that the C-shaped frame 310 is pulled down by the truss 210 and compresses the shock-absorbing airbag 320. At this time, the shock-absorbing airbag 320 is compressed, and the gas inside the shock-absorbing airbag 320 is compressed to buffer the vibration. When the gas inside the shock-absorbing airbag 320 is compressed, the first piston rod 360 can be pushed to move the first piston rod 360 upward. At the same time, the tension spring 380 connected to the bottom of the first piston rod 360 is stretched. The elongation of the tension spring 380 buffers the upward movement of the first piston rod 360, thereby improving the shock-absorbing effect of the shock-absorbing airbag 320.
[0064] Among the optional methods of this embodiment, the more preferred ones are:
[0065] The shock absorbing mechanism 300 also includes a first piston cylinder 340, which is connected to the upper part of the C-shaped frame 310, and the pipeline 350 is connected to the first piston cylinder 340. A piston plate 370 is slidably connected in the first piston cylinder 340, and the piston plate 370 is connected to the top of the first piston rod 360; a second piston cylinder 391 is connected to the side of the C-shaped frame 310, and an air pipe 394 is connected between the second piston cylinder 391 and the first piston cylinder 340, and a second piston rod 392 is slidably connected in the second piston cylinder 391, and a counterweight block 393 is connected to the top of the second piston rod 392. The inner diameter of the second piston cylinder 391 is smaller than that of the first piston cylinder 340, so that when the piston plate 370 moves upward, the second piston rod 392 drives the counterweight block 393 to move upward synchronously and quickly.
[0066] The side of the C-shaped frame 310 is connected to a fixing seat 390, and the first piston cylinder 340 is connected to the fixing seat 390. When the first piston rod 360 moves upward, the piston plate 370 connected to the top of the first piston rod 360 moves upward synchronously in the first piston cylinder 340. At this time, the medium in the first piston cylinder 340 is squeezed by the piston plate 370 and transferred to the second piston cylinder 391 through the air pipe 394, so that the second piston rod 392 is pushed and moves upward. At this time, the counterweight block 393 connected to the top of the second piston rod 392 moves upward synchronously. Due to the high vibration frequency generated by the vibrating rod 250, the shock-absorbing airbag 320 The compression speed is fast, so that the medium in the first piston cylinder 340 is quickly transferred to the second piston cylinder 391. The inner diameter of the second piston cylinder 391 is smaller than the inner diameter of the first piston cylinder 340, so that the second piston rod 392 can quickly move up and reset, so that the counterweight block 393 stops moving up and then moves down. The inertia generated in this process applies an upward force to the C-shaped frame 310, so that the downward pulling force applied to the moving seat 120 due to the overweight state of the vibrating rod 250 is partially decomposed, ensuring that the displacement amplitude of the moving seat 120 is reduced, and at the same time, the downward pulling force on the single beam 110 will not increase significantly.
[0067] Among the optional methods of this embodiment, the more preferred ones are:
[0068] There are four C-shaped frames 310 , and the four C-shaped frames 310 are connected to four corners of the truss 210 respectively.
[0069] By providing four C-shaped frames 310 , no matter which orientation the vibrating rod 250 is in, there are corresponding shock-absorbing air bags 320 and rubber blocks 330 to provide cushioning for it, thereby ensuring a shock-absorbing effect.
[0070] Regarding the structure of the lifting mechanism 400, specifically:
[0071] The lifting mechanism 400 includes a cylinder 410, an inner wall of the cylinder 410 is connected to an electromagnetic coil 420, a movable seat 120 is connected to a bracket 460, an iron rod 450 is connected to the bracket 460, and the iron rod 450 is inserted into the cylinder 410. When the counterweight block 393 moves upward, the electromagnetic coil 420 is energized so that the iron rod 450 is subjected to an upward lifting force.
[0072] When the counterweight block 393 moves upward, the electromagnetic coil 420 near the corresponding counterweight block 393 is energized, so that the iron rod 450 inserted in the corresponding cylinder 410 is subjected to the upward lifting force of magnetic attraction, and further applies an upward lifting force to the movable seat 120, thereby reducing the impact of the vibrating rod 250 on the movable seat 120 when it is in an overweight state.
[0073] Among the optional methods of this embodiment, the more preferred ones are:
[0074] The lifting mechanism 400 also includes a fixed frame 440, which is placed on the ground. A slider 430 is connected to the top of the cylinder 410, and the slider 430 slides on the fixed frame 440; a cross bar 470 is connected to the side wall of the cylinder 410, and a vertical slide groove cooperating with the cross bar 470 is opened on the movable seat 120.
[0075] The fixed frame 440 is set to provide support for the cylinder 410. The cylinder 410 slides on the fixed frame 440 through the slider 430. The fixed frame 440 is placed parallel to the single beam 110. When the movable seat 120 moves, it can drive the cylinder 410 to move synchronously by driving the cross bar 470, so that the positions of the cylinder 410 and the iron rod 450 always correspond. The cross bar 470 can slide vertically on the movable seat 120, so that the reaction force generated by the electromagnetic coil 420 on the iron rod 450 when it is energized is applied to the fixed frame 440.
[0076] A concrete construction method, applied to a high-speed railway prefabricated box girder concrete intelligent vibration reduction type vibrating device, comprises the following steps:
[0077] The robot arm 240 is adjusted to the working position; the main control machine obtains and stores the concrete rheological data, the bubble image data during concrete vibration and the audio data during concrete vibration, filters and organizes the concrete rheological data, the bubble image data during concrete vibration and the audio data during concrete vibration and sends them to the display terminal; the concrete rheological data, the bubble image data during concrete vibration and the audio data during concrete vibration received by the main control machine are processed by the data relay system and transmitted through the 5G communication network; the concrete rheological data, the bubble image data during concrete vibration and the audio data during concrete vibration received by the main control machine are processed by the data relay system and transmitted through the 5G communication network The audio data during concrete vibration is acquired by the total station 140 and the sensor; after the main control machine determines that the concrete rheology data, the bubble image data during concrete vibration and the audio data during concrete vibration are qualified, it controls the robotic arm 240 to move to the next vibration position; wherein, each time the main control machine vibrates the concrete, it first uses the vibration time determined by the concrete experiment as the basic value of the vibration time, and then judges the vibration state according to the mathematical model constructed based on the sensor collected data, and makes a small adjustment on the basic value of the vibration time, automatically starts and stops the vibration and delays the vibration, and sends a start command to the sound and light alarm when the vibration is finished.
[0078] A data relay system is installed near the total station 140 for collecting and processing information from various sensors and for supplying power to various sensors and vibrators 250. The data transmission between the data relay system and the sensors is connected in series using network cables to form a local area network. The power supply system is also connected in series. A 5G communication network is set up at a high place near the beam yard control room and near the data terminal system. Data is transmitted between the data relay system and the 5G communication network, and between the 5G communication network and the data terminal system through wireless transmission. When performing concrete operations, the data terminal system main control machine sends a data collection command to the data relay system. The data relay system collects data from each sensor according to the command sequence and performs corresponding processing. Then, the data is transmitted to the data terminal system through the 5G communication network. The main control computer of the system and the data terminal system store and analyze the collected data. The rheological data of concrete, the bubble image data during concrete vibration, and the audio data during concrete vibration are all collected at high frequency and transmitted to the data terminal in real time. Each type of sensor is set with a basic threshold data indicator according to the experiment. Then, as the data is collected and sorted through data filtering, the data collected by various sensors are displayed in real time on the control center screen and the mobile phones of various monitoring managers. Each time the main control computer of the data terminal system vibrates the concrete, it first uses the vibration time determined by the concrete experiment as the basic value of the vibration time, and then judges the vibration state based on the mathematical model constructed according to the sensor collected data, makes a small adjustment to the basic value of the vibration time, and automatically starts and stops the vibration and delays it. When the vibration is finished, it is reminded through sound and light.
[0079] Among the optional methods of this embodiment, the more preferred ones are:
[0080] The position adjustment steps of the robot arm 240 include: setting up a precision engineering coordinate system on site, setting up multiple fixed positions with known coordinates around the site, and installing the prism 260; obtaining the execution of the vibration operation and data acquisition commands, controlling the moving seat 120 to drive the total station 140 and the truss 210 to move to the operation range; the total station 140 obtains the data of the prism 260 installed on the site and solves the coordinates of the total station 140, and then the total station 140 collects the data of the prism 260 connected to the mounting seat 230, and solves the coordinates of the mounting seat 230 according to the solved coordinates of the total station 140; controlling the operation of the hydraulic rod 220 according to the position coordinates of the prefabricated beam to adjust the coordinates of the mounting seat 230 until the robot arm 240 is deployed after the adjustment is completed; the deployment angle of the robot arm 240 is executed according to the data provided by the system, and after the robot arm 240 is deployed, the two-dimensional code image recognition is used to determine again whether the positions of the vibrating rod 250 and the total station 140 are correct, otherwise the adjustment continues.
[0081] The engineering coordinate system is arranged on site. The position coordinates of the precast beams are also known. According to the 360-degree prism arranged in the beam yard, the total station 140 is accurately positioned through the back intersection method. When the concrete vibration operation starts, a command is sent to perform the vibration operation and data collection. The mobile seat 120 carries the total station 140 and the operating equipment to the approximate position. The total station 140 searches for and collects the data of the prism 260 with coordinates arranged in the beam yard, sends the data and solves the coordinates of the total station 140, and then the total station 140 collects the data of the prism 260 at the mounting seat 230. Mirror 260 data, solve the coordinates of the mounting base 230, and adjust the position of the mounting base 230 up and down according to the coordinates of the precast beam position. If the adjustment of the mounting base 230 position is not completed, repeat the up and down adjustment of the mounting base 230 position, otherwise the robot arm 240 is deployed, and the robot arm 240 extends to the specified appropriate angle according to the data provided by the system. The QR code image recognition is used to determine again whether the vibration and detection positions are correct. If not, the software continues to adjust the deployment angle of the robot arm 240 until the position of the vibrating rod 250 and the aiming angle posture are qualified.
