[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-3 As shown, one embodiment of the present invention provides a linkage rotating device for duct flange assembly, including a first rotating mechanism, a connecting mechanism, and a second rotating mechanism; The first rotating mechanism is provided with a connecting mechanism, and the first rotating mechanism is used to drive the connecting mechanism to rotate in a first direction; The connecting mechanism is equipped with a second rotating mechanism. The drive end of the second rotating mechanism is connected to a support plate 7 for mounting the flange gripping device. The second rotating mechanism is used to drive the support plate 7 to rotate in a second direction.

[0021] By setting up a first rotating mechanism and a second rotating mechanism, the angle of the support plate 7 can be adjusted in two directions. In use, the flange gripping device is installed on the support plate 7, and the flange gripped by the device moves synchronously with the support plate 7. The first rotating mechanism drives the connecting mechanism to rotate in the first direction, and the second rotating mechanism drives the support plate 7 to rotate in the second direction, allowing the flange to be adjusted in space to any assembly angle precisely matched to the duct port. This linked rotating device replaces the traditional manual flange rotation method, significantly reducing labor intensity and improving assembly efficiency and angle positioning accuracy.

[0022] According to one embodiment of the present invention, the first direction is perpendicular to the second direction.

[0023] By setting the first direction to be perpendicular to the second direction, the linkage rotation device has the ability to independently adjust the angle in the horizontal and vertical planes. The two rotational degrees of freedom are perpendicular to each other, making control simple and adjustment intuitive. It can quickly adjust the flange to the matching angle that is precisely adapted to the duct port. At the same time, the structure is compact and occupies little space, making it easy to integrate into automated production lines.

[0024] According to one embodiment of the present invention, the first rotating mechanism includes a drive component; The drive assembly includes a first motor 1 and a reducer 2, the reducer 2 having an input shaft and an output shaft; The output end of the first motor 1 is connected to the input shaft of the reducer 2.

[0025] The first motor 1 is preferably a servo motor with a built-in high-precision encoder, which can provide real-time feedback on the rotation angle of the motor rotor. Combined with real-time feedback of the angular position from the external control system, this ensures repeatability and positioning accuracy under closed-loop control. The reducer 2 has an input shaft and an output shaft. The reducer 2 is preferably a Hypo gear transmission device, which features zero backlash, high rigidity, and high transmission accuracy. This effectively eliminates mechanical transmission backlash and elastic deformation errors, ensuring transmission precision. The output end of the first motor 1 is connected to the input shaft of the reducer 2, and the two can be coaxially connected via a coupling to ensure smooth power transmission. The output shaft of the reducer 2 is arranged vertically, and its top end is fixedly connected to the base 3 of the connecting mechanism via bolts or a key.

[0026] In actual operation, the first motor 1 receives a command signal from the control system, driving the first motor 1 to rotate. After the speed reduction and torque amplification effect of the reducer 2, the output shaft of the reducer 2 drives the connecting mechanism to rotate in the horizontal plane. Due to the combination of servo motor and Hybo gear transmission device, the positioning accuracy can reach ±0.1°, which fully meets the stringent requirements for angular accuracy during the assembly of nuclear power plant duct flanges.

[0027] According to one embodiment of the present invention, the connecting mechanism includes a base 3 and a support structure 4; The support structure 4 is mounted on the base 3, and the base 3 is connected to the output shaft of the reducer 2. The second rotating mechanism is connected to the support structure 4.

[0028] According to one embodiment of the present invention, the connecting mechanism further includes a cylinder 5, the support structure 4 is slidably connected to the base 3, the fixed end of the cylinder 5 is disposed on the support structure 4, and its pushing end is connected to the base 3.

[0029] The sliding fit between the support structure 4 and the base 3 ensures the smooth operation and accurate positioning during the flange transfer process. The cylinder 5 can drive the second rotating mechanism to move horizontally and adjust the distance between the gripping device and the flange.

[0030] The base 3 has a countersunk hole structure on its bottom wall in the middle, which is adapted to high-strength T-bolts for quick installation of the entire telescopic device into the working position. The countersunk hole structure is located between the two sets of slide rails 13.

[0031] According to one embodiment of the present invention, the support structure 4 is provided with a receiving area, the base 3 includes a plate 301 and a mounting plate 302 connected to each other, the fixed end of the cylinder 5 is located in the receiving area, and its pushing end is fixedly connected to the mounting plate 302.

[0032] Specifically, the plate 301 is a plate-shaped structure that extends along the length of the base 3, and the upper surface of the plate 301 is flat. The mounting plate 302 is a vertically arranged plate-shaped structure, and its lower end is fixedly connected to one end of the plate 301. The mounting plate 302 and the plate 301 are perpendicular to each other, that is, the plate surface of the mounting plate 302 is perpendicular to the length of the base 3.

[0033] Furthermore, the mounting plate 302 and the flat plate 301 can be connected by welding, bolting, or integral molding.

[0034] The support structure 4 is provided with a receiving area, and the fixed end of the drive component is located within the receiving area. By accommodating the fixed end of the drive component inside the support structure 4 rather than outside, the internal space of the support structure 4 can be fully utilized, reducing the volume occupied by the drive component outside the support structure 4. This helps to reduce the overall size of the telescopic device and improve the structural compactness of the telescopic device.

[0035] Mounting plate 302 provides a fixed connection point for the pushing end of the drive assembly. The pushing end of the drive assembly extends from the receiving area and passes through the side of the support structure 4 opposite to mounting plate 302, ultimately being fixedly connected to mounting plate 302. When cylinder 5 operates, because the pushing end is fixedly connected to mounting plate 302, and mounting plate 302 is fixedly connected to plate 301, the pushing end is constrained by mounting plate 302 and cannot move freely. The fixed end is driven by the reaction force, causing the entire support structure 4 to slide relative to base 3 along the length of base 3. This drive arrangement allows the pushing and pulling force of cylinder 5 to be efficiently converted into the sliding force of support structure 4, and the force transmission path is simple and direct, which is beneficial to improving transmission efficiency and control accuracy.

[0036] According to one embodiment of the present invention, the support structure 4 and the base 3 are slidably connected by a guide assembly, the guide assembly including a guide structure, the guide structure including a slider 12 and a slide rail 13; The slide rail 13 is connected to the base 3, and the slider 12 is connected to the bottom of the support structure 4. At least one slider 12 is slidably connected to the slide rail 13.

[0037] The slide rail 13 is a long, strip-shaped guide rail component, which is fixedly installed on the upper surface of the base 3. The length direction of the slide rail 13 is the same as the length direction of the base 3. The slide rail 13 can be made of metal, such as steel. The cross-sectional shape of the slide rail 13 can be rectangular, trapezoidal, or I-shaped.

[0038] Preferably, the slide rail 13 is detachably connected to the base 3 by fasteners such as bolts. The base 3 has mounting holes (e.g., bolt holes) that mate with the fasteners, and the slide rail 13 has corresponding countersunk holes. The fasteners pass through the countersunk holes on the slide rail 13 and are screwed into the bolt holes on the base 3, thus securely fixing the slide rail 13 to the base 3. This detachable connection facilitates the installation, adjustment, and replacement of the slide rail 13 after wear.

[0039] In another embodiment, the base 3 and the support structure 4 are fixedly connected by bolts.

[0040] According to one embodiment of the present invention, the second rotating mechanism includes a geared motor 6; The fixed end of the geared motor 6 is connected to the support structure 4, and its driving end is fixedly connected to the support plate 7.

[0041] Specifically, the fixed end of the geared motor 6 is fixedly connected to the bearing plate of the support structure 4 by bolts, and the output shaft of the geared motor 6 extends horizontally and is fixedly connected to the support plate 7.

[0042] According to one embodiment of the present invention, the first rotating mechanism further includes a positioning detection component; The positioning detection component is used to detect whether the base 3 has rotated into position.

[0043] Specifically, the positioning detection component is electrically connected to the control system. When the base 3 rotates to a preset angle position, the positioning detection component sends a positioning signal to the control system. After receiving the signal, the control system sends a stop command to the first motor 1, causing the first motor 1 to stop running.

[0044] By adding a positioning detection component, the physical detection and confirmation of the rotational position of the base 3 is realized. Together with the encoder feedback of the servo motor, a dual positioning verification mechanism is formed. Even if the encoder signal is abnormal or accumulates errors, the positioning detection component can still provide a reliable positioning signal, effectively preventing positioning deviations caused by control errors or mechanical failures, and significantly improving the operational reliability and safety of the device.

[0045] According to one embodiment of the present invention, the positioning detection component includes a detection plate 8 and a positioning sensor 9; The detection plate 8 is connected to the output shaft, and the position sensor 9 is connected to the fixed end of the reducer 2.

[0046] According to one embodiment of the present invention, a groove 10 is provided on one side of the output shaft, and one end of the detection plate 8 is fixedly connected to the groove 10 by fasteners; The position sensor 9 has a notch 11 on one side for the end of the detection plate 8 away from the output shaft to pass through.

[0047] The detection plate 8 is a long strip-shaped thin plate structure made of metal. One end of it is connected to the output shaft of the reducer 2, and the other end is a free end that rotates with the output shaft of the reducer 2.

[0048] The position sensor 9 is connected to the fixed end of the reducer 2, or the position sensor 9 is fixedly connected to the fixed end of the first motor 1. Specifically, the position sensor 9 is fixed to the housing of the reducer 2 or the base of the first motor 1 by a mounting bracket, maintaining a relatively stationary position relative to the output shaft of the reducer 2. The position sensor 9 is positioned towards the rotation path of the detection plate 8. When the detection plate 8 rotates with the output shaft to a preset position, the free end of the detection plate 8 enters the detection area of ​​the position sensor 9, triggering the position sensor 9 to output a detection signal.

[0049] The position sensor 9 is preferably a photoelectric sensor, including a transmitter and a receiver arranged opposite each other. When the free end of the detection plate 8 passes through the detection gap between the transmitter and the receiver, it blocks the light path and triggers the sensor signal output. The position sensor 9 can also be a Hall sensor, with a magnetic element provided on the free end of the detection plate 8. When the detection plate 8 rotates to the vicinity of the Hall sensor, it triggers the signal output.

[0050] One end of the detection plate 8 is fixedly connected to the groove 10 by a fastener. Specifically, the mounting end of the detection plate 8 has a through hole. The mounting end of the detection plate 8 is inserted into the groove 10, aligning the through hole with the threaded hole on the bottom wall of the groove 10. The fastener is a bolt, with its threaded portion passing through the through hole and screwed into the threaded hole, firmly clamping and fixing the detection plate 8 in the groove 10. This installation method creates a rigid connection between the detection plate 8 and the output shaft, allowing the detection plate 8 to rotate synchronously with the output shaft, ensuring consistency between the detection position and the actual rotation angle of the output shaft.

[0051] The position sensor 9 has a notch 11 on one side for the end of the detection plate 8 away from the output shaft to pass through. The notch 11 is a U-shaped opening that penetrates the housing of the position sensor 9, and the transmitting end and the receiving end are respectively located on the two side walls of the notch 11. When the output shaft rotates and the free end of the detection plate 8 enters the notch 11, the detection plate 8 blocks the light emitted by the transmitting end, triggering the sensor signal output.

[0052] According to one embodiment of the present invention, the support plate 7 includes a plate body 701 and an annular boss 702; The output end of the geared motor 6 is connected to a positioning boss, which is inserted into the annular boss 702.

[0053] The annular boss 702 is a circular structure that protrudes from the plate 701. The central axis of the annular boss 702 coincides with the geometric center of the plate 701, ensuring the dynamic balance of the support plate 7 when it rotates.

[0054] The output end of the geared motor 6 is connected to a locating boss. The outer diameter of the locating boss matches the inner diameter of the annular boss 702, forming a shaft-hole fit. During assembly, the locating boss is inserted into the annular boss 702, with a transition fit or interference fit between them to ensure coaxiality between the locating boss and the annular boss 702. The annular boss 702 and the output end of the geared motor 6 are fixedly connected by multiple bolts distributed along the circumference.

[0055] The insertion and mating structure of the positioning boss and the annular boss 702 plays a radial positioning role, ensuring that the rotation center of the support plate 7 coincides with the axis of the output shaft of the geared motor 6, thus guaranteeing rotational accuracy.

[0056] The shaft hole insertion and mating structure of the positioning boss and the annular boss 702 achieves high-precision coaxial positioning and reliable connection between the output end of the geared motor 6 and the support plate 7, making torque transmission more stable, effectively avoiding rotational swaying and vibration caused by assembly eccentricity, and improving the accuracy and stability of flange angle adjustment.
