[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0029] like Figure 1As shown, an intelligent concrete vibrating device provided by an embodiment of the present invention includes an equipment support frame 1 and a reel mechanism 2, a lifting drive mechanism 3, an anti-offline mechanism 4, an encoding mechanism 5, a control box 8, a limit ring 6 and a scraper 7 installed on the equipment support frame 1, and also includes a drag cable 9 and a vibrating rod 10. The upper end of the drag cable 9 is wound around the reel mechanism 2, and the lower end passes through the anti-offline mechanism 4, the encoding mechanism 5, the limit ring 6 and the scraper 7 in sequence. It is fixedly connected to the vibrating rod 10 vertically downward. The lifting drive mechanism 3 is used to drive the reel mechanism 2 to rotate to retract and release the drag cable 9; the anti-offline mechanism 4 is used to monitor the off-line signal of the drag cable 9; the encoding mechanism 5 is used to record the retraction and release distance of the drag cable 9 in real time. The control box 8 has a built-in controller, and the lifting drive mechanism 3, the anti-offline mechanism 4, the encoding mechanism 5 and the vibrating rod 10 are respectively connected to the controller signal. The controller collects feedback information from the anti-offline mechanism 4 and the encoding mechanism 5 to determine the state of the equipment itself, and controls the lifting drive mechanism 3 and the vibrating rod 10 according to the preset information to realize intelligent vibration operation.

[0030] like Figure 2-3 As shown, the reel mechanism 2 includes a reel 21 and a reel shaft 22. The drag cable 9 is wound on the reel 21, and the reel 21 rotates to complete the cable reeling and unreeling action. The reel 21 is installed on the reel shaft 22. A collector ring 23 is provided on the reel shaft 22. The wires on one side of the collector ring 23 are connected to the drag cable 9 on the reel 21, and the wires on the other side pass through the reel shaft 22 and are connected to the electrical components in the control box 8, so as to realize the power supply and control of the drag cable 9 when the reel 21 rotates. When the reel 21 reels the wire, the reel 21 drives the drag cable 9 to rise upward, and the vibrator 10 is lifted by the cable tension; when the reel 21 unwinds the wire, the vibrator 10 at the end of the cable drives the cable to move downward under the action of gravity.

[0031] Continue to see Figure 2-3 The lifting drive mechanism 3 is arranged on the side of the reel mechanism 2, and includes a driving motor 31, a driving reducer 32, a driving pinion 33, and a driving gear 34. The driving motor 31 and the driving reducer 32 are fixedly installed on the equipment support frame 1, the output shaft of the driving motor 31 is connected to the driving reducer 32, the output shaft of the driving reducer 32 is fixedly connected to the driving pinion 33, the driving pinion 33 is meshed with the driving gear 34, and the driving gear 34 is fixedly connected to the reel shaft 22. The driving motor 31 is electrically connected to the controller in the control box 8. Under the rotation of the driving motor 31, the driving pinion 33 drives the driving gear 34 to rotate, thereby driving the reel 21 to rotate, and realizing the reel 21 The reel 21 retracts and releases the cable 9. The reel 21 retracts and releases the cable to drive the vibrator 10 at the end of the cable to rise and fall, so as to realize the plugging and unplugging action of the vibrator 10.

[0032] Since the downward movement of the cable is completely dependent on the action of the vibrating rod 10, if the cable is released too quickly or the vibrating rod 10 encounters an obstacle and cannot fall, it will cause the cable to be derailed and deviate from the designed path. To prevent the cable from being derailed, the intelligent concrete vibrating device is provided with an anti-derailment mechanism 4. Figure 4 As shown, the anti-offline mechanism 4 includes an anti-offline bracket 41, a steering wheel 42 and a proximity switch 43; the anti-offline bracket 41 is fixedly installed on the equipment support frame 1, and a limiting groove 411 is provided on the anti-offline bracket 41, and first waist circular holes 412 are provided on both sides of the limiting groove 411, and the steering wheel 42 is located in the limiting groove 411, and the rotating shaft of the steering wheel 42 is passed through the first waist circular hole 412; the dragging cable 9 passes between the steering wheel 42 and the inner wall of the limiting groove 411; the proximity switch 43 is arranged on the side of the rotating shaft of the steering wheel 42, and a reset spring is attached to the structure of the proximity switch 43 to realize its compression reset. When the drag cable 9 is subjected to downward movement force, the steering wheel 42 is driven to deviate toward the proximity switch side, the rotating shaft of the steering wheel 42 compresses the reset spring, and the proximity switch reads a limit signal, indicating that the cable is in a straightened state; if the drag cable 9 is off-line, the drag cable 9 has no downward pulling force on the steering wheel 42, the steering wheel 42 is reset under the action of the reset spring, and there is no in-place signal from the proximity switch, which indicates that the cable is in a loose state, that is, off-line state.

[0033] like Figure 5 As shown, the encoding mechanism 5 includes an encoding wheel bracket 51, an encoding wheel 52, an encoder 53, a clamping wheel 54 and a clamping spring 55; the encoding wheel bracket 51 is fixedly installed on the equipment support frame 1, and a mounting groove 511 is provided on the encoding wheel bracket 51, and a group of round holes and a group of second waist round holes 512 are provided on both sides of the mounting groove 511; the encoding wheel 52 and the clamping wheel 54 are installed side by side in the mounting groove 511, wherein the rotating shaft of the encoding wheel 52 is passed through the round hole, and the rotating shaft of the clamping wheel 54 is passed through the second waist round hole 512, and the rotating shafts of the encoding wheel 52 and the clamping wheel 54 are connected by a clamping spring 55; the dragging cable 9 passes between the encoding wheel 52 and the clamping wheel 54; the clamping wheel 54 clamps the dragging cable 9 on the encoding wheel 52 through the clamping spring 55; the encoder 53 is coaxially arranged with the encoding wheel 52. Under the action of the compression spring 55, the cable is close to the encoding wheel 52 in real time. When the cable moves, it can drive the encoding wheel 52 to rotate. The encoder 53 coaxial with the encoding wheel 52 can record the rotation state of the encoding wheel 52 in real time, so as to be used for real-time conversion and recording of the movement distance of the cable.

[0034] like Figure 6 As shown, a cable adapter mounting seat 91 is provided at the end of the drag cable 9, and the cable adapter mounting seat 91 is fixedly connected and electrically connected to the main body of the vibrating rod to realize the disassembly and assembly of the vibrating rod. The vibrating rod 10 adopts a high-frequency vibrating rod 10 with an embedded motor, and the control module of the vibrating rod 10 is arranged inside the control box 8.

[0035] like Figure 7 As shown, the controller in the control box 8 includes a data acquisition module, a lifting control module and a vibration control module, a human-computer interaction module and a computing storage module. The data acquisition module collects relevant status information of the device itself, including but not limited to relevant information fed back by the encoder 53 and the proximity switch 43. The proximity switch 43 feeds back whether the towing cable 9 is normally retracted and released; and determines whether the vibration rod 10 reaches the specified vibration depth according to the distance information fed back by the encoder 53.

[0036] The lifting control module adjusts the relevant position of the vibrating rod 10 according to the operation requirements, controls the insertion and extraction speed and the vibration depth of the vibrating rod 10; the vibration control module controls the vibration frequency and vibration time of the vibrating rod 10 according to the relevant data. The lifting control module and the vibration control module cooperate with each other to adjust the parameters of the lifting drive motor 31 and the parameters of the vibration motor to realize intelligent vibration operation.

[0037] The human-computer interaction module is used to input or select concrete parameter information, and display the optimal vibration frequency, vibration time and plug-in speed of the corresponding concrete vibration, as well as other status information of the vibration equipment. The calculation and storage module is used to store data information of other modules and provide control parameter information for the lifting control module and the vibration control module.

[0038] For further optimization, a limit ring 6 is arranged on the equipment support frame 1 to limit the retraction and release path of the drag cable 9 to prevent the cable from deviating from the designed path.

[0039] For further optimization, a scraper 7 is arranged at the end of the equipment support frame 1. When the vibrator 10 is lifted, the cable is pulled out of the concrete and some cement slurry is on the surface. The slurry is scraped off by the scraper 7 to prevent the cable from being unable to be normally retracted or released after recovery due to solidification of the slurry.

[0040] For further optimization, the towing cable 9 adopts a shielded cable with double outer layers of protection: the inner layer is an insulating material to ensure that the cable is powered; the outer layer is a high-strength wear-resistant material, which meets the cable towing requirements and the wear and aging resistance requirements.

[0041] For further optimization, a lifting ring is arranged above the equipment support frame 1 for connecting the vibrating equipment with other mounting frames.

[0042] Further optimization, the intelligent concrete vibrating equipment provided by the present invention has a lifting ring, a cable drum 21 installation center, and a center of gravity of the equipment that are close to the extension line of the vertical end of the drag cable 9 or coincide with the extension line of the vertical section of the cable, to ensure that the cable transceiver or the vibrating rod 10 will not deviate or swing to a large extent during the lifting and recovery process.

[0043] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
