Description

Technical Field

[0001] The invention relates to the technical field of concrete vibrating and molding, and in particular to a concrete vibrating device capable of detecting posture and pressure. Background Art

[0002] Vibration is a key step in concrete construction. It can make the coarse aggregate evenly distributed, the admixture and the paste fully react, and the bubbles in the fresh concrete are expelled to improve the overall density and impermeability of the later concrete.

[0003] During the vibration process, the posture control of the vibrator becomes the key to achieving the vibration quality of special parts. If a posture sensor and a pressure sensor are added to the vibrating rod, the corresponding angle data and pressure data can be detected. However, the vibrating rod vibrates severely in the working state, resulting in the posture sensor and the pressure sensor being unable to truly reflect the insertion status of the vibrating rod (such as the depth of insertion into the concrete). Summary of the invention

[0004] The present invention provides a concrete vibrating device capable of detecting posture and pressure, so as to solve the technical problem that the posture sensor and the pressure sensor cannot be directly applied to the vibrating rod due to severe vibration in the working state.

[0005] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0006] A concrete vibrating device capable of detecting posture and pressure, comprising a vibrating rod, a posture sensing module and a pressure sensing module, wherein the pressure sensing module is installed at the bottom end of the vibrating rod, and the posture sensing module is installed inside the vibrating rod;

[0007] The vibrating rod is vertically inserted into the concrete.

[0008] Furthermore, the attitude sensing module includes a mounting frame, the mounting frame is connected to the vibrating rod, and a fiber optic gyroscope is connected to the middle of the mounting frame.

[0009] Furthermore, the attitude sensing module also includes two fixing plates, which are respectively arranged at the upper and lower parts of the fiber optic gyroscope, and a connecting rod is connected between the two fixing plates, and the connecting rod is inserted into the mounting frame, and the connecting rod is located on the upper and lower sides of the mounting frame and is sleeved with springs.

[0010] Furthermore, the posture sensing module also includes eight first piston cylinders connected to the four corners of the two fixed plates, and the eight first piston cylinders are slidably connected with a cylinder-type piston rod, and the two ends of the connecting rod are respectively connected to the two first piston cylinders symmetrically arranged up and down, and the outer wall and inner wall of the cylinder-type piston rod are respectively attached to the inner wall of the first piston cylinder and the outer wall of the connecting rod, and the two ends of the spring are respectively abutted against the cylinder-type piston rod and the mounting frame, and when the reciprocating sliding frequency of the connecting rod relative to the mounting frame increases, the cylinder-type piston rod slides toward the outside of the first piston cylinder to compress the spring, thereby reducing the reciprocating sliding stroke of the connecting rod.

[0011] Furthermore, the posture sensing module also includes a second piston cylinder, and the number of the second piston cylinders is two. The two second piston cylinders are respectively arranged on the upper and lower sides of the fiber optic gyroscope and fixedly connected to the inner wall of the vibrating rod. The two fixed plates are connected with cylindrical piston rods, and the two cylindrical piston rods slide in the second piston cylinder respectively. When the connecting rod slides back and forth, the second piston cylinder injects air into the first piston cylinder, and the first piston cylinder discharges the injected air outwardly. Moreover, when the reciprocating sliding frequency of the connecting rod increases, the injection speed is higher than the speed of the first piston cylinder discharging the injected air outwardly, so that the cylinder-type piston rod slides toward the outside of the first piston cylinder to compress the spring.

[0012] Furthermore, the second piston cylinder is connected to an air suction pipe and an exhaust pipe, both of which are provided with one-way valves, the exhaust pipe is connected to the first piston cylinder, the first piston cylinder is connected to a pressure relief pipe, and the pressure relief pipe is provided with a pressure valve.

[0013] Furthermore, the pressure sensing module includes a flexible PZT composite thin film pressure sensor, the upper and lower parts of which are respectively connected to a lower pressure frame and an upper pressure frame, and the lower pressure frame and the upper pressure frame are respectively attached to the outer wall and the inner wall of the vibrating rod.

[0014] Furthermore, a sealing ring is provided between the pressing down frame and the vibrating rod.

[0015] Furthermore, a rectangular airbag is connected to the lower surface of the upper pressure frame, and the rectangular airbag is attached to the inner wall of the vibrating rod.

[0016] Furthermore, the four pressure relief pipes located at the bottom are all connected to the rectangular airbag, and when the sliding frequency of the connecting rod increases, the pressure relief pipe injects air into the rectangular airbag to further expand the rectangular airbag;

[0017] The rectangular air bag is provided with a pressure valve.

[0018] The beneficial effects of the present invention are analyzed as follows:

[0019] A concrete vibrating device capable of detecting posture and pressure comprises a vibrating rod, a posture sensing module and a pressure sensing module, wherein the pressure sensing module is installed at the bottom end of the vibrating rod, and the posture sensing module is installed inside the vibrating rod; the posture sensing module comprises a mounting frame, which is connected to the vibrating rod, and a fiber optic gyroscope is connected to the middle of the mounting frame; the posture sensing module also comprises two fixing plates, which are respectively arranged at the upper and lower parts of the fiber optic gyroscope, a connecting rod is connected between the two fixing plates, the connecting rod is plugged into the mounting frame, and the connecting rod is located on the upper and lower sides of the mounting frame and is sleeved with springs.

[0020] The vibrating rod is the main part of the device, which is responsible for transmitting vibration energy to the concrete to eliminate bubbles in the concrete and improve the density and uniformity of the concrete. The attitude sensing module installed in the vibrating rod can sense the angle of the vibrating rod, which is beneficial to the control of the vibration process. The pressure sensing module at the bottom of the vibrating rod detects the pressure at the bottom of the vibrating rod, and as the insertion depth of the vibrating rod increases, the pressure value detected by the pressure sensing module increases, and it can be concluded whether the vibrating rod is in the deep or shallow part of the concrete. When the vibrating rod is working, the axial vibration is transmitted to the fiber optic gyroscope and two fixed plates of the attitude sensing module, so that the two fixed plates drive the connecting rod to slide on the mounting frame, thereby compressing the spring, and the spring relieves the vibration transmitted to the fiber optic gyroscope.

[0035] Examples, such as Figure 1-Figure 6As shown, a concrete vibrating device capable of detecting posture and pressure includes a vibrating rod 100, a posture sensing module 200 and a pressure sensing module 300. The pressure sensing module 300 is installed at the bottom end of the vibrating rod 100, and the posture sensing module 200 is installed inside the vibrating rod 100. The vibrating rod 100 is vertically inserted into the concrete.

[0036] The working mechanism of the vibrating device provided in this embodiment is as follows:

[0037] The vibrating rod 100 is the main part of the device, which is responsible for transmitting vibration energy to the concrete to eliminate bubbles in the concrete and improve the density and uniformity of the concrete. The posture sensing module 200 installed in the vibrating rod 100 can sense the angle of the vibrating rod 100, which is beneficial to the control of the vibration process. The pressure sensing module 300 at the bottom of the vibrating rod 100 detects the pressure at the bottom of the vibrating rod 100, and as the insertion depth of the vibrating rod 100 increases, the pressure value detected by the pressure sensing module 300 increases, and it can be concluded whether the vibrating rod 100 is in the deep or shallow part of the concrete.

[0038] Among the optional methods of this embodiment, the more preferred ones are:

[0039] The attitude sensing module 200 includes a mounting frame 210 . The mounting frame 210 is connected to the vibrating rod 100 . A fiber optic gyroscope 201 is connected to the middle of the mounting frame 210 .

[0040] The attitude sensing module 200 includes a fiber optic gyroscope 201 . The fiber optic gyroscope 201 is installed in the vibrating rod 100 through a mounting frame 210 . The fiber optic gyroscope 201 detects the attitude angle of the vibrating rod 100 .

[0041] Regarding the structure of the posture sensing module 200, specifically:

[0042] The attitude sensing module 200 also includes two fixing plates 220, which are respectively arranged at the upper and lower parts of the fiber optic gyroscope 201. A connecting rod 231 is connected between the two fixing plates 220, and the connecting rod 231 is inserted into the mounting frame 210. The connecting rod 231 is located on the upper and lower sides of the mounting frame 210 and is sleeved with springs 233.

[0043] When the vibrating rod 100 is working, the axial vibration is transmitted to the fiber optic gyroscope 201 and the two fixing plates 220 , so that the two fixing plates 220 drive the connecting rod 231 to slide on the mounting frame 210 , thereby compressing the spring 233 , and the spring 233 alleviates the vibration transmitted to the fiber optic gyroscope 201 .

[0044] Among the optional methods of this embodiment, the more preferred ones are:

[0045] The posture sensing module 200 also includes eight first piston cylinders 230 connected to the four corners of the two fixed plates 220, and the eight first piston cylinders 230 are all slidably connected with a cylinder-type piston rod 232. The two ends of the connecting rod 231 are respectively connected to the two first piston cylinders 230 symmetrically arranged in the upper and lower parts. The outer wall and the inner wall of the cylinder-type piston rod 232 are respectively attached to the inner wall of the first piston cylinder 230 and the outer wall of the connecting rod 231. The two ends of the spring 233 are respectively in contact with the cylinder-type piston rod 232 and the mounting frame 210. When the reciprocating sliding frequency of the connecting rod 231 relative to the mounting frame 210 increases, the cylinder-type piston rod 232 slides toward the outside of the first piston cylinder 230 to compress the spring 233, thereby reducing the reciprocating sliding stroke of the connecting rod 231.

[0046] The upper and lower fixing plates 220 are fixedly connected by the first piston cylinder 230 and the connecting rod 231. When the vibration frequency intensifies, the cylinder piston rod 232 slides out of the first piston cylinder 230, thereby compressing the length of the spring 233, which leads to a reduction in the increase in the degree of deformation of the spring 233. At this time, the thrust of the spring 233 on the mounting frame 210 increases, resulting in a reduction in the sliding stroke of the fiber optic gyroscope 201 relative to the mounting frame 210, ensuring that the supporting force of the spring 233 on the fiber optic gyroscope 201 can increase with the vibration frequency of the fiber optic gyroscope 201, thereby ensuring the shock absorption effect on the fiber optic gyroscope 201.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] The posture sensing module 200 also includes a second piston cylinder 260, and the number of the second piston cylinders 260 is two. The two second piston cylinders 260 are respectively arranged on the upper and lower sides of the fiber optic gyroscope 201 and are fixedly connected to the inner wall of the vibrating rod 100. The two fixed plates 220 are connected with cylindrical piston rods 280, and the two cylindrical piston rods 280 slide in the second piston cylinder 260 respectively. When the connecting rod 231 slides back and forth, the second piston cylinder 260 injects air into the first piston cylinder 230, and the first piston cylinder 230 discharges the injected air outwardly. Moreover, when the reciprocating sliding frequency of the connecting rod 231 increases, the injection speed is higher than the speed of the first piston cylinder 230 discharging the injected air outwardly, so that the cylindrical piston rod 232 slides toward the outside of the first piston cylinder 230 to compress the spring 233.

[0049] The vibration generated when the vibrating rod 100 is working causes the two fixed plates 220 to fluctuate axially, thereby driving the cylindrical piston rod 280 to slide back and forth inside the second piston cylinder 260. The second piston cylinder 260 extracts air through the exhaust pipe 270 and injects air into the first piston cylinder 230 through the exhaust pipe 250, so that the cylindrical piston rod 232 slides out of the first piston cylinder 230 due to the air pressure, thereby compressing the length of the spring 233.

[0050] Among the optional methods of this embodiment, the more preferred ones are:

[0051] The second piston cylinder 260 is connected to an exhaust pipe 270 and an exhaust pipe 250, both of which are provided with one-way valves. The exhaust pipe 250 is connected to the first piston cylinder 230, and the first piston cylinder 230 is connected to a pressure relief pipe 240, which is provided with a pressure valve.

[0052] In order to prevent the cylinder-type piston rod 232 from extending indefinitely from the first piston cylinder 230, a pressure relief pipe 240 is connected to the first piston cylinder 230. A flow limiting valve or a pressure valve is arranged on the pressure relief pipe 240 so that the air entering into the first piston cylinder 230 can be discharged. In addition, when the vibration frequency of the vibrating rod 100 increases, the sliding speed of the cylindrical piston rod 280 relative to the second piston cylinder 260 increases. At this time, the air intake of the first piston cylinder 230 is greater than the exhaust volume, so that the cylinder-type piston rod 232 can maintain the state of sliding out of the first piston cylinder 230. When the vibration frequency of the vibrating rod 100 is low, the air intake of the first piston cylinder 230 is less than the exhaust volume, so that the compression degree of the spring 233 is low, so that the stroke of the fiber optic gyroscope 201 is not excessively reduced.

[0053] Regarding the structure of the pressure sensing module 300, specifically:

[0054] The pressure sensing module 300 includes a flexible PZT composite thin film pressure sensor 310 , the upper and lower parts of which are respectively connected to a lower pressing frame 311 and an upper pressing frame 330 , which are respectively attached to the outer wall and the inner wall of the vibrating rod 100 .

[0055] The lower pressing frame 311 and the upper pressing frame 330 can be installed with the flexible PZT composite thin film pressure sensor 310 through nuts, so that the flexible PZT composite thin film pressure sensor 310 is easy to disassemble and assemble and maintain later.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] A sealing ring 320 is disposed between the pressing frame 311 and the vibrating rod 100 .

[0058] The provision of the sealing ring 320 isolates the inner and outer spaces of the vibrating rod 100 , thereby preventing concrete from flowing into the interior of the vibrating rod 100 .

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] A rectangular airbag 340 is connected to the lower surface of the upper pressing frame 330 , and the rectangular airbag 340 is attached to the inner wall of the vibrating rod 100 .

[0061] Among the optional methods of this embodiment, the more preferred ones are:

[0062] The four pressure relief pipes 240 at the bottom are all connected to the rectangular airbag 340 . When the sliding frequency of the connecting rod 231 increases, the pressure relief pipe 240 injects air into the rectangular airbag 340 to further expand the rectangular airbag 340 . A pressure valve is provided on the rectangular airbag 340 .

[0063] The first piston cylinder 230 at the lower part is connected to the rectangular airbag 340 through the pressure relief pipe 240. The air discharged from the first piston cylinder 230 enters the rectangular airbag 340, causing the rectangular airbag 340 to expand, thereby pushing the upper pressure frame 330 to move upward. The upper pressure frame 330 drives the flexible PZT composite thin film pressure sensor 310 to move upward, so that the degree of squeezing of the sealing ring 320 by the lower pressure frame 311 increases. A pressure valve is also provided on the rectangular airbag 340 to prevent the rectangular airbag 340 from excessive expansion and rupture, thereby ensuring that the flexible PZT composite thin film pressure sensor 310 contacts the concrete, allowing it to accurately collect pressure data, and further improving the sealing of the lower part of the vibrating rod 100.
