DETAILED DESCRIPTION The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, a flange transportation device includes a length-adjustable beam 1, and height-adjustable brackets 2 are provided at both ends of the beam 1. The spacing between the two brackets 2 can be adjusted according to the diameter of the flange. A shipping mechanism 5 for lifting the flange is provided on the inner side of the bracket 2. The shipping mechanism 5 includes a support beam 506 that slides up and down with the bracket 2, and a support fork 505 is provided at both ends of the support beam 506. A positioning mechanism 4 is provided above the support beam 506. The positioning mechanism 4 includes a driving box 402 connected to the bracket 2, and a lifting seat 409 that can move up and down is connected to the driving box 402. A positioning block 414 that can move left and right is connected to the bottom of the lifting seat 409. The positioning block 414 is provided with a positioning roller 415 that pulls the inner wall of the flange and a pressure plate 418 that presses the upper end of the flange to ensure the stability of the flange on the support fork 505. An anti-jump mechanism 3 that presses the flange is connected to the bottom of the beam 1 to further ensure the stability and safety of the flange during transportation.

[0018] The specific structure is as follows: like Figure 2 As shown, the crossbeam 1 includes two parallel connecting sleeves 101, which are connected and fixed to each other. Telescopic rods 103 are inserted at both ends of the connecting sleeves 101, and the telescopic rods 103 are connected to the bracket 2. A first hydraulic cylinder 102 is fixed on one side of the connecting sleeve 101, and the piston rod of the first hydraulic cylinder 102 is connected to the upper end of the bracket 2. The length of the crossbeam 1 is adjusted by the first hydraulic cylinder 102, thereby changing the distance between the two brackets 2 to adapt to flanges of different diameters. like Figure 3 As shown, bracket 2 includes two parallel, connected support sleeves 203. A support rod 201 is inserted into the upper end of each support sleeve 203. A second hydraulic cylinder 202 is fixed to one side of each support sleeve 203, driving the support rod 201 up and down. The height of crossbeam 1 is adjusted by second hydraulic cylinder 202, with a maximum height of no more than 2 meters. This height is adjusted based on the number of transport flanges (single flange or multiple flanges stacked and bundled together) or the height of obstacles to be crossed during unladen transport, enhancing its versatility and ability to pass unladen obstacles.

[0019] The bottom of the support sleeve 203 is connected to a base 208 perpendicular to the beam 1. A universal wheel 207 is provided at the lower end of the base 208. Support screws 206 are provided at both ends of the base 208. A support block is provided at the bottom of the support screw 206, and a turning handle is provided at the upper end of the support screw 206. When loading and unloading materials, the support screw 206 is rotated to make the support block touch the ground for support, thereby preventing the device from moving and improving the stability of loading and unloading materials. A reinforcing rod 205 is provided between the upper middle portion of the support sleeve 203 and the base 208, and an angle plate 209 is connected between the bottom of the support sleeve 203 and the base 208 for reinforcement. A handle 204 is connected to the side wall of the support sleeve 203 to facilitate pushing the device.

[0020] like Figure 3 、 Figure 4 As shown, the outer wall of the support sleeve 203 is provided with a first guide rail 210, and the outer side of the support sleeve 203 is provided with a horizontal lifting rod 502, which cooperates with the first guide rail 210 through a slider, and a fourth hydraulic cylinder 501 for driving the lifting rod 502 is fixed to one side of the support sleeve 203, as shown in FIG. Figure 5As shown, both ends of the lifting rod 502 are connected to the joist 506 via a first tie rod 503. A second guide rail 212 is provided on the inner sidewall of the support sleeve 203. A second tie rod 508 is connected to the sidewall of the joist 506. The second tie rod 508 cooperates with the second guide rail 212 via a slider. The first guide rail 210 and the second guide rail 212 ensure the smoothness of the vertical movement of the lifting rod 502 and the joist 506. A first guide rod 211 is connected to the sidewall of the support sleeve 203. The first tie rod 503 cooperates with the first guide rod 211 via a sliding sleeve, further improving the smoothness and stability of the lifting and lowering of the joist 506.

[0021] A baffle 507 is provided at the upper end of the joist 506, and the side wall of the baffle 507 is flush with the side wall of the joist 506. A fourth motor 504 is provided at both ends of the joist 506 to drive the support fork 505 to rotate. The angle of the support fork 505 can be adjusted by the fourth motor 504 to adapt to the support of flanges of different diameters, and at the same time facilitate the cooperation between the support fork 505 and the flange; after use, the support fork 505 can be rotated to the bottom of the joist 506 for storage to improve safety.

[0022] In addition, a center line is drawn in the middle of the joist 506 and the baffle 507 so that the symmetry line of the flange is aligned with the center line during transportation, thereby further improving stability.

[0023] A second guide rod 403 and a first lead screw 404 are provided in the driving box 402. A second motor 401 is provided at the upper end of the driving box 402 to drive the first lead screw 404. Figure 6 As shown, a slide 405 is provided at one end of the lifting seat 409, and a nut sleeve 407 cooperating with the first screw 404 and a guide sleeve 406 cooperating with the second guide rod 403 are provided on the side wall of the slide 405. A reinforcing plate 408 is connected between the slide 405 and the lifting seat 409. A third guide rail 411 and a second screw 412 are provided at the lower end of the lifting seat 409. One end of the second screw 412 is driven by a third motor 410. The upper end of the positioning block 414 is provided with a slider 413 cooperating with the third guide rail 411 and a nut sleeve 407 cooperating with the second screw 412. Two positioning rollers 415 are provided at the bottom of the positioning block 414, and a first proximity switch 416 is provided at the bottom of the positioning roller 415, so that the positioning roller 415 stops pulling after contacting the inner wall of the flange. The two positioning rollers 415 cooperate with the inner wall of the flange to position the flange to prevent the flange from sliding on the support fork 505. A second proximity switch 417 is provided on one side of the pressure plate 418 to ensure that the pressure plate 418 can just press the upper end of the flange, thereby ensuring the stability of the flange on the support fork 505.

[0024] like Figure 7As shown, the anti-jump mechanism 3 includes a rocker arm 303 connected to the connecting sleeve 101, and there are two rocker arms 303. A first motor 301 for driving the rocker arm 303 is fixed on the side wall of the connecting sleeve 101 through a connecting plate 302. An adjusting rod 304 is inserted at the lower end of the rocker arm 303. A third hydraulic cylinder 305 for driving the adjusting rod 304 to slide is fixed on one side of the rocker arm 303. The end of the adjusting rod 304 is connected to a receiving tube 306. A slidable pressure rod 308 is inserted at both ends of the receiving tube 306. The length of the pressure rod 308 is adjusted according to the diameter of the flange. A positioning bolt 307 for fixing the pressure rod 308 is provided on the side wall of the receiving tube 306. A pressing sleeve 309 is provided at the end of the pressure rod 308. The pressing sleeve 309 is made of rubber, which can increase friction and prevent flange wear.

[0025] like Figure 8 As shown, the method of use is explained using the example of transporting a single flange: According to the diameter of the flange, adjust the distance between the two brackets 2 so that the spacing between the two support beams 506 is larger than the diameter of the flange. Move the device so that the device is placed on the outside of the flange, and the crossbeam 1 is located directly above the flange. The line connecting the center lines of the two support beams 506 should pass through the center of the flange as much as possible (two points can be marked on the side wall of the flange in advance, and the line connecting the two points passes through the center of the circle. Move the device so that the center lines of the two support beams 506 are aligned with these two points respectively). Turn the support screw 206 to fix the base 208. Lower the joist 506 so that the supporting fork 505 is close to the ground (the flange is generally not placed directly on the ground, and the bottom is generally supported by wooden blocks or wooden poles, so there will be a gap between the flange and the ground), drive the fourth motor 504, and rotate the supporting fork 505 to the bottom of the flange; the fourth hydraulic cylinder 501 drives the joist 506 to rise slowly, and the supporting fork 505 lifts the flange, and the lifting height can be 10-30cm, generally not more than 50cm; move the positioning roller 415 downward so that the lower end of the positioning roller 415 is lower than the upper end surface of the flange, and then the third motor 410 drives the positioning block 414 to move, so that the positioning roller 415 moves toward the bracket 2, and the positioning roller 415 stops after contacting the inner wall of the flange (the first proximity switch 416 sensing position), then move the lifting seat 409 downward, stopping when the pressure plate 418 just presses against the upper end of the flange (second proximity switch 417 sensing position). Adjust the length of the pressure rod 308 so that the distance between the two pressure sleeves 309 is no less than the inner diameter of the flange, and secure the pressure rod 308 with the positioning bolt 307. Start the first motor 301, rotate the rocker 303 downward, and simultaneously start the third hydraulic cylinder 305 to adjust the extension and retraction of the adjustment rod 304 so that the pressure rod 308 is roughly in the middle position above the flange. Once the pressure sleeve 309 presses against the upper end of the flange, stop the first motor 301. Raise the support screw 206, and use the handle 204 to push the device to move, thus completing the transfer of the flange. After transfer, first raise the anti-jump mechanism 3 and positioning mechanism 4, then slowly lower the support beam 506 so that the flange falls on the pre-prepared support wooden blocks. The support fork 505 rotates to the sides, moving from the bottom of the flange, and the device is removed from above the flange. When the device is not in use, the length of the beam 1 can be adjusted to the shortest, the height of the bracket 2 can be adjusted to the lowest, the support fork 505 can be retracted into the bottom of the support beam 506, and the base 208 can be supported and fixed by the support screw 206 to minimize the volume and reduce space occupancy.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
