It should be noted that the web of the field bridge main beam is usually a long plate, so the turning device also has a long and wide side in order to receive the web, the plate length direction is consistent with the length direction of the web, and the plate width direction is consistent with the width direction of the web.

[0050] With such arrangement, the beam structure assembly machine is applied to the manufacture of the main beam of the field bridge. The turning devices are arranged in two rows side by side and installed at the manufacturing site, so that the turning devices are kept in a state where they can receive the plate body. The left and right web plate bodies used to constitute the main beam are hoisted onto the turning devices. Through the adjustment of the first centering mechanism 1 and the second centering mechanism 2, the web plate bodies are both in preset positions. Then the turning device drives the web plate bodies to turn along the long sides until the left and right web plate bodies are in an upright and relative state. After the web plate is in place, it is easy to carry out the subsequent main beam welding process. The entire assembly process is carried out mechanically, the front, rear, left, and right positioning references are controllable, the assembly accuracy is high, no excessive manual intervention is required, manual participation is reduced, the operating difficulty is greatly reduced, and the safety factor is also improved, which solves the problems of high operating difficulty and low safety factor in the assembly process of the main beam of the field bridge in the prior art.

[0051] In a specific embodiment, the first centering mechanism 1 includes a plate clamp 12 and a first power assembly 11; the plate clamp 12 can be opened and closed to clamp the plate body, and can specifically be a common steel plate clamp 12; the first power assembly 11 is connected to the flipping device, and the first power assembly 11 is connected to the plate clamp 12 and can drive the plate clamp 12 to move along the length direction of the plate to drive the plate body to move, thereby adjusting the position of the web plate body on the flipping device. The first power assembly 11 can be an electric cylinder, an oil cylinder or other linear actuator.

[0052] In this way, after the plate clamp 12 clamps and fixes the plate body, it can drive the plate body to adjust its front and rear position. Of course, the first centering mechanism 1 is configured to include a first power assembly 11, and it is also feasible to use the first power assembly 11 to unidirectionally push the plate body to move along the length direction of the plate.

[0053] In a more specific embodiment, the first centering mechanism 1 also includes a first positioning block 13, which is fixed on the flipping device and can block the end of the plate in the length direction of the plate; and / or, the first centering mechanism 1 also includes a first positioning sensor 14, which is communicatively connected to the first power assembly 11 and can sense the plate, and the first positioning sensor 14 can be a photoelectric detection switch or an infrared sensor.

[0054] With this arrangement, the web plate body is limited to a preset position in the length direction of the plate through the physical limitation of the block and the setting of the sensor, which is conducive to the rapid alignment of the left and right web plates and improves the degree of automation.

[0055] In a preferred embodiment, the flip device is provided with a first centering mechanism 1 at both ends in the plate length direction. In this arrangement, since the web of the main beam is usually welded in sections, the first centering mechanism 1 is provided at both ends, which facilitates the actual operation process, and any side can be reasonably selected as the alignment side according to different positions.

[0056] In another specific embodiment, the second centering mechanism 2 includes a second power assembly 21 and a second positioning block 22; the second power assembly 21 is arranged on both sides of the flipping device in the board width direction, and the second power assemblies 21 located on both sides can be arranged relatively or staggered; the second positioning block 22 is connected to the second power assembly 21, and can be driven by the second power assembly 21 to move along the board width direction to push the board body to move. The second power assembly 21 can be set as an electric cylinder, that is, a structure in which a motor drives a ball screw, and the second positioning block 22 is connected to the nut of the ball screw. This setting method is conducive to reducing the installation space occupied by the second centering mechanism 2; of course, it is also feasible that the second power assembly 21 is set as an oil cylinder and the second positioning block 22 is set on the piston rod.

[0057] With such arrangement, when the second power assembly 21 on one side is actuated, or when the second power assemblies 21 arranged opposite to each other are actuated, the second positioning blocks 22 opposite to each other are respectively blocked on both sides of the web plate body, and they cooperate together to limit the web plate body at a preset position, so that the positions of the left and right webs are highly symmetrical; moreover, according to different web sizes, after the second power assembly 21 on one side is actuated, the position of the second positioning block 22 can be kept fixed to form an alignment reference, and only the second power assembly 21 on the other side is operated as an actuator for adjusting the position of the web plate body.

[0058] Of course, in addition to the above-mentioned form, it is also feasible that the second centering mechanism 2 is set on one side, clamps the plate body through a mechanical clamp, and then drives the web plate body to move; or, a second power component 21 is set on one side, and only a second positioning block 22 is set on the other side, and one-way adjustment is also feasible.

[0059] In another specific embodiment, the flipping device includes a base 3, a support platform 4, a magnetic structure, and a flipping drive mechanism 5; the base 3 is installed on the ground; the support platform 4 is rotatably connected to the base 3 and can support the plate, and the first centering mechanism 1 and the second centering mechanism 2 are both arranged on the support platform 4; the magnetic structure is arranged on the support platform 4 and can adsorb the plate on the support platform 4; the flipping drive mechanism 5 is arranged between the base 3 and the support platform 4, and can drive the support platform 4 to rotate relative to the base 3. The flipping drive mechanism 5 can specifically be a linear cylinder, and its two ends are respectively hinged to the base 3 and the support platform 4, or the flipping drive mechanism 5 is set as a rotating cylinder, which is arranged at the hinge of the base 3 and the support platform 4, and it is also feasible to drive the support platform 4 to rotate around the axis.

[0060] With such arrangement, the support platform 4 can be flipped, and the first centering mechanism 1 and the second centering mechanism 2 are integrated on the support platform 4 to adjust the position of the web plate body on the support platform 4. The magnetic structure is integrated on the support platform 4 to ensure that the web plate body is still firmly fixed on the support platform 4 when flipping.

[0061] In a preferred embodiment, the base 3 includes a base 31, a bracket 32 ​​and a translation drive mechanism 33; the base 31 is installed on the ground; the bracket 32 ​​is slidably connected to the base 31 through a slider rail structure, and is rotatably connected to the support platform 4; the translation drive mechanism 33 is arranged on the base 31 and can drive the bracket 32 ​​to translate along the width direction of the board. The translation drive mechanism 33 can specifically include a motor and a rack and pinion structure, the rack is fixed in the base 31, the motor and the gear are arranged on the bracket 32, and the motor drives the gear to rotate, and the rotating gear runs on the rack to complete the translation action; or, it is also feasible that the translation drive mechanism 33 is set in the form of a motor-driven ball screw.

[0062] With such arrangement, the two rows of support platforms 4 arranged side by side can be close to or away from each other, so that the web plates after flipping have different distances to adapt to main beam designs of different specifications.

[0063] In a preferred embodiment, the flipping device includes a plurality of support platforms 4 arranged along the length direction of the board, a machine base 3 is provided under each support platform 4, and adjacent support platforms 4 can be connected or spaced apart; among all the support platforms 4 located in the same row, a first centering mechanism 1 is provided on the support platforms 4 located at the head and tail ends in the length direction of the board; and a second centering mechanism 2 is provided on each support platform 4.

[0064] In this way, the flip device is configured as a structure composed of multiple separate parts, and the combined modularization formed by the support table 4 and the base 3 can flexibly increase or decrease the number of modules and adjust the distance between adjacent modules according to the length of the web and the space of the manufacturing site, thereby improving the flexibility of tooling assembly.

[0065] In another preferred embodiment, a rolling body 7 capable of rolling contact with the plate body is provided on the support platform 4, the rolling body 7 is embedded in the support platform 4 and can rotate when subjected to force, and the cross-section height of the rolling body 7 is slightly higher than the height of the electromagnet 6. This arrangement makes it easy to adjust the position of the web plate body, and the movement resistance on the support platform 4 is small, thereby reducing the power consumption of the first centering mechanism 1 and the second centering mechanism 2.

[0066] Specifically, the magnetic attraction structure includes a plurality of electromagnets 6 dispersedly distributed on the support platform 4. When the web plate body adjusts its position on the support platform 4, the electromagnet 6 is in a power-off state. When the position adjustment is completed, the electromagnet 6 is energized and absorbs the web plate body to position it on the support platform 4.

[0067] In another preferred embodiment, the adsorption surfaces of all the electromagnets 6 are located on the same plane; or, the adsorption surfaces of all the electromagnets 6 have various heights and / or angles.

[0068] With such arrangement, the plate body fixed by the magnetic attraction structure is not limited to a conventional flat plate structure; the multiple electromagnets 6 of the magnetic attraction structure are arranged at different heights and angles, so that the plate body fixed by the magnetic attraction structure can also be a bent plate body, or a special-shaped plate body with a curved surface, thereby realizing the assembly of a special-shaped structure.

The first power component 11 is started, so that the web moves in the plate length direction and stops at the preset position under the limit of the first positioning block 13. The electromagnet 6 is energized, the flipping drive mechanism 5 is started, and the support platform 4 drives the web to flip to 90°. The translation drive mechanism 33 is started, and the support platform 4 drives the web to move to the set position, so that the web is in the set assembly station.
