The positioning device includes an annular ring body 7, a plurality of annular positioning frames 12 equidistantly installed on the ring body 7, and a driving device installed on the ring body 7 for driving the positioning frame 12 to move toward and away from the center direction of the ring body 7. The plurality of positioning frames 12 mentioned above are staggered with each other and will not get stuck with each other when moving.

[0025] In one embodiment, the positioning frame 12 includes a U-shaped locking frame 121, and one side of the arc-shaped locking frame 121 is close to the center of the ring body 7. When in use, the parts are placed at the center of the ring body 7, and the driving device drives multiple locking frames 121 to move to the side away from the parts, so that the multiple locking frames 121 overlap with each other to clamp and fix the parts, and the regulating device drives the positioning device to move in multiple directions, so that the fixed parts are close to the installation position of the circular cold box and aligned with it.

[0026] During the specific implementation, relevant personnel push the mobile cart to the installation location of the circular cold box, and place the large components at the center of the ring body 7. At this time, the large components are simultaneously located in the arc of multiple locking frames 121. Subsequently, the multiple locking frames 121 are driven by the driving device to adjust and move to the side away from the components, so that the arc-shaped side of the multiple locking frames 121 can jointly clamp and fix the components, thereby enabling the initial stable fixation of the components. Subsequently, the positioning device is driven by the regulating device to move along the left and right, up and down, and front and back directions of the processing platform 3, so that the fixed components are aligned with the fixed positions on the circular cold box, thereby facilitating the subsequent installation of the components. The device is easy to operate and the adjustment is stable and reliable, which can fix and drive the components to move close to the circular cold box, thereby ensuring the effect of convenient installation of the components.

[0027] In one embodiment, the mobile cart includes a body 1 and a moving wheel 2 rotatably mounted on the body 1, the moving wheel 2 is in contact with the ground and has a brake pad movably mounted thereon, and the regulating device includes a linear module A 4 laterally mounted on the processing platform 3, a push rod 5 mounted on the moving end of the linear module A 4, and a linear module B 6 mounted on the telescopic end of the push rod 5, and a ring body 7 is mounted on the moving end of the linear module B 6.

[0028] In a specific implementation, after the vehicle body 1 is moved to a corresponding location through the moving wheels 2, the brake pads can be operated and the moving wheels 2 can be locked to prevent the vehicle body 1 from sliding, so as to ensure the stability of subsequent operations. The push rod 5 can be controlled by the linear module A 4 to move along the front and rear directions of the processing platform 3, and the linear module B 6 can be controlled by the push rod 5 to move along the up and down directions of the processing platform 3. The ring body 7 can be controlled by the linear module B 6 to move along the left and right directions of the processing platform 3, so that the components located at the center of the ring body 7 are adjusted accordingly and aligned and close to the installation position of the circular cold box.

[0029] In one embodiment, the driving device includes a transmission ring rotatably mounted on a ring body, a worm rotatably mounted on the bottom of the transmission ring, a plurality of gears A in contact with the transmission ring, and a gear B mounted on the rotating shaft of gear A and rotating synchronously with gear A. The transmission ring includes a ring body, a plurality of worm gear teeth fixedly connected in an annular shape to the outer wall of the ring body, and a plurality of gear teeth fixedly connected in an annular shape to the inner wall of the ring body, the worm gear teeth mesh with the worm, the positioning frame also includes a rack mounted on the inner wall of the lock frame, gear A meshes with the gear teeth, and gear B meshes with the rack.

[0030] In specific implementation, the rotating worm causes the ring body with worm gear teeth to rotate, and at the same time drives gear A that meshes with the gear teeth to rotate. During the rotation process of gear A, gear B will rotate synchronously with it, and gear B meshes with the rack, thereby driving the rack and the locking frame to move. The locking frame will move toward or away from the component located at the center of the ring body to clamp and fix components of various diameters.

[0031] In one embodiment, the positioning frame also includes a plurality of rollers rotatably mounted on an inner wall of one side of the arc-shaped locking frame, and the plurality of rollers are equidistantly distributed in a ring shape. When in use, the components clamped and fixed by the plurality of locking frames overlapping each other will contact the rollers. Therefore, after the components are aligned with the installation position of the circular cold box, the components can be pushed to move along the rotation direction of the rollers and approach the circular cold box until they are in contact with the circular cold box. This can further improve the convenience of aligning and contacting the components with the installation position of the circular cold box. In actual situations, the rollers may include a rubber layer that increases friction to prevent the components from sliding and falling off.

[0032] In one embodiment, a motor is installed on the ring body, and the worm is installed on the rotating shaft of the motor. When in use, the worm is driven by the motor to rotate, and the transmission ring is driven to rotate.

[0033] In one embodiment, a supporting device 14 is installed at the bottom of the ring body 7. The supporting device 14 includes a telescopic rod connected to the ring body 7 and a rolling ball installed at the bottom end of the telescopic rod. A spring is installed in the telescopic rod, and the rolling ball is in contact with the processing platform 3 to support the ring body 7 during movement, adjustment and stationary state.

[0034] In one embodiment, the ball in the supporting device 14 is wrapped with a flexible layer. When the ring body 7 is adjusted for multi-directional displacement with the regulating device, the telescopic rod can be adjusted accordingly with the adjustment height of the ring body 7. At this time, the spring plays a supporting role. The contact between the ball and the processing platform 3 will make the transmission ring 8 move very smoothly. The above-mentioned flexible layer can be a silicone layer to increase the rolling smoothness of the ball.
