Description

Technical Field

[0001] This utility model belongs to the field of concrete vibration technology, specifically relating to an integrated immersion vibrator that can prevent wire tangling. Background Technology

[0002] In the construction of tunnel secondary lining concrete pouring using a trolley, concrete vibration is necessary to prevent voids, uneven pouring, and insufficient compaction. The vibration device directly affects the pouring quality. Practice has shown that immersion vibrators can meet the vibration requirements. However, because immersion vibrators require the vibrator rod to be inserted into the concrete, it is necessary to avoid reinforcing steel bars if they are located in the direction of the rod's extension or retraction; otherwise, the reinforcing steel mesh may be damaged. Existing technologies, such as the "Automatic Obstacle Avoidance Immersion Vibrator and Vibration Method" disclosed in application number 202510698932.6, require an external current module to monitor current changes in real time, resulting in a complex overall structure.

[0003] Meanwhile, in existing technologies, the vibrator is fixed to the trolley template, while the power cord is connected to the rotating body. This can easily lead to cord tangling when the vibrator rotates. Figure 1 As shown, this type of stranded wire is prone to damaging the protective cable sheath. When the sheath wears down, the conductors inside the stranded wire will be exposed. In the humid construction environment and under the conductive characteristics of the trolley's own steel structure, it is easy to cause electric shock accidents. Even if no electric shock accident occurs, cable twisting will hinder current transmission, causing motor defects or overload, and eventually leading to coil burnout. When dealing with stranded wire faults, it is necessary to stop the machine for maintenance, which will not only interrupt concrete pouring and form cold joints, but may also cause quality defects such as honeycomb and pitting due to discontinuous vibration. In addition, when solving cable entanglement, operators are sometimes forced to change the vibration position, which will affect the uniformity of vibration. The process of repositioning the vibrator will also consume a lot of time, seriously affecting the construction progress. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background technology and provide an integrated insert vibrator that can prevent wire entanglement. This vibrator eliminates the traditional external sensors and associated cables, and integrates the entire obstacle avoidance system into the drive unit of the vibrator rod. Furthermore, it solves the problem of cable entanglement by adding a conductive slip ring.

[0005] The objective of this utility model is achieved through the following technical solution: An integrated insert vibrator for preventing wire twisting includes a base, a servo-electric slide, a vibrating rod, a servo rotary motor, a frame housing, a servo controller, a PLC controller, and a conductive slip ring. The base has a circular opening in the center, on which a rotatable turntable is coaxially mounted. The servo rotary motor is eccentrically mounted on the turntable. The output shaft of the servo rotary motor passes through the turntable and is connected to a gear. An internal gear ring meshes with the gear inside the circular opening. The servo rotary motor adjusts the rotation angle of the turntable on the base by rotating relative to the gear ring. A cover plate is installed on the base to block the circular opening. The servo-electric slide is mounted on the bottom surface of the turntable. The extension and retraction direction of the moving slide is perpendicular to the bottom surface of the turntable. A vibrating rod, eccentrically passing through the turntable and cover plate, is mounted on the mounting base of the servo-electric slide. The machine frame is installed on the bottom surface of the turntable. A housing enclosing the servo-electric slide, vibrating rod, and servo rotary motor is mounted on the machine frame. A partition separating the servo rotary motor and the servo-electric slide is installed on the machine frame. The servo controller and PLC controller are mounted on the side wall of the partition below the servo rotary motor. The PLC controller is connected to the servo-electric slide and the servo rotary motor respectively through two servo controllers. A conductive slip ring is installed at the end of the housing, and the cable provides power to the vibrator through the conductive slip ring.

[0006] The lower part of the machine frame is equipped with a support base plate for supporting the servo electric slide. A switch is installed on the bottom surface of the support base plate, and a control button is installed on the outer shell on one side of the switch.

[0007] The cover plate is equipped with a sealing ring that mates with the vibrating rod.

[0008] The integrated insert vibrator provided by this utility model, which can prevent wire from getting tangled, has the following beneficial effects: (1) By integrating the servo controller and PLC controller into the frame of the machine cover, the independent current detection module can be eliminated, and the structure of the vibrator can be more integrated. With the help of the conductive slip ring, the problem of cable entanglement when the frame of the machine cover rotates can be avoided, which effectively ensures the vibration effect. (2) The conductive slip ring can protect the cable and avoid wear, leakage and short circuit burnout of the motor caused by excessive twisting of the cable. At the same time, it can also avoid defects such as cold joints and honeycomb caused by the stop of the vibrator, thus ensuring the uniformity and process accuracy of the poured concrete.

Detailed Implementation

[0017] like Figures 2-6As shown, the integrated insert vibrator for preventing wire tangling provided in this embodiment includes a base 1, a servo-electric slide 3, a vibrating rod 4, a servo rotary motor 5, a machine frame 6, a servo controller 7, a PLC controller 8, and a conductive slip ring 10. The outer side of the base 1 has bolt holes for connection to the secondary lining trolley. A circular opening 11 is machined in the middle of the base 1. A rotatable turntable 2 is coaxially mounted on the circular opening 11. A servo rotary motor 5 is eccentrically mounted on the turntable 2. The output shaft of the servo rotary motor 5 passes through the turntable 2 and is connected to a gear 51. An internal gear ring 12, meshing with gear 51, is installed inside the opening 11. The servo rotary motor 5 adjusts the rotation angle of the turntable 2 on the base 1 by rotating gear 51 relative to the internal gear ring 12. A cover plate 13 is installed on the base 1 to block the circular opening 11. The cover plate 13 is connected to the base 1 by a rotary sealing ring to prevent concrete leakage. The servo electric slide 3 is installed on the bottom surface of the turntable 2. The extension and retraction direction of the servo electric slide 3 is perpendicular to the bottom surface of the turntable 2. An eccentric device is installed on the mounting base of the servo electric slide 3, which passes through the turntable 2 and the cover plate 1 in sequence. The vibrator 4 of the turntable 3 is covered with a sealing ring on the cover plate 13 to prevent concrete from seeping into the circular opening 11 between the cover plate 13 and the vibrator 4. The machine frame 6 is installed on the bottom surface of the turntable 2. The machine frame 6 is welded from angle steel. The machine frame 6 is equipped with a housing 9 that encloses the servo electric slide table 3, the vibrator 4 and the servo rotary motor 5. The machine frame 6 is equipped with a partition plate 61 that separates the servo rotary motor 5 and the servo electric slide table 3. The servo controller 7 and the PLC controller 8 are installed below the servo rotary motor 5. On the side wall of the partition 61, the PLC controller 8 is connected to the servo electric slide 3 and the servo rotary motor 5 respectively through two servo controllers 7. The servo controllers 7 are connected to the servo electric slide 3 and the servo rotary motor 5 through encoding lines. The lower part of the machine frame 6 is equipped with a support base plate 62 to support the servo electric slide 3. A switch 63 is installed on the bottom surface of the support base plate 62. A control button 91 is installed on the outer shell 9 on one side of the switch 63. The conductive slip ring 10 is installed at the end of the outer shell 9. The cable provides power to the vibrator through the conductive slip ring 10.

[0018] The method of using this utility model is as follows: First, the base 1 is installed on the secondary lining trolley through bolt holes. During concrete pouring, the servo electric slide 3 controls the vibrator 4 to extend into the concrete for vibration. If the vibrator 4 encounters the reinforcing mesh and is obstructed, the servo electric slide 3 will be overloaded. At this time, the torque required for rotation increases. The servo electric slide 3 transmits this overload signal to the servo controller 7 through the encoder line. The servo controller 7 then transmits the data to the PLC controller 8. After receiving this signal, the PLC controller 8 controls the servo electric slide 3 to retract according to the set program, and then controls the servo rotary motor 5 to rotate. When the servo rotary motor 5 rotates at a certain angle, it rotates relative to the internal gear ring 12 through the gear 51, causing the turntable 2 to rotate 30°, 45°, 60°, etc. along the base 11. At this time, the extended end of the vibrator 4 avoids the steel mesh, thereby achieving the purpose of avoiding the steel bars. Since the servo controller 7 and the PLC controller 8 are both located inside the machine frame 6, their wires are short and their response speed is fast. They can compress the process of the traditional PLC processing current threshold signal from 200~500ms to 50ms, and there is no need to worry about the loosening of connectors or aging of lines caused by external line exposure.

[0019] During the rotation of the servo rotary motor 5, the machine frame 6 will rotate with the turntable 2. At this time, under the action of the conductive slip ring 10, the cable will not rotate with the machine frame 6, so the cable will not be kinked or wrapped around the outer shell 9, thus ensuring the continuity of concrete vibration.

[0020] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
