[0020] Embodiment: A single Y-axis heavy-duty gantry truss, see attached Figure 1 -Attached Figure 7, including an X-axis crossbeam 1, a Y-axis crossbeam 2, a guide rail 12, a slider 22 and a Z-axis vertical beam 3, wherein two X-axis crossbeams 1 are provided, the length directions of the two X-axis crossbeams 1 are parallel and arranged horizontally, and two columns 11 are fixedly connected to the bottom of both ends of the X-axis crossbeam 1; the Y-axis crossbeam 2 is arranged between the two X-axis crossbeams 1 and the length direction is perpendicular to the two X-axis crossbeams 1; each X-axis crossbeam 1 is fixedly connected to a guide rail 12, and the length direction of the guide rail 12 is arranged along the length direction of the X-axis crossbeam 1; the Y-axis crossbeam 2 Two sliders 22 are provided at both ends of the Y-axis crossbeam 2, and the sliders 22 at both ends of the Y-axis crossbeam 2 slide on the guide rails 12 of the two X-axis crossbeams 1 respectively along the length direction of the guide rails 12, and the two sliders 22 on each guide rail 12 form a group; the Z-axis vertical beam 3 is arranged on one side of the Y-axis crossbeam 2 and is arranged vertically, and the Z-axis vertical beam 3 is located in the middle position of the two sliders 22 of the same group along the direction of the guide rail 12, and the Z-axis vertical beam 3 is arranged in the middle position in the length direction of the Y-axis crossbeam 2, so that the Z-axis vertical beam 3 is located in the center of the four sliders 22.

[0021] Two sliders 22 are provided at both ends of the Y-axis crossbeam 2 and the position of the Z-axis vertical beam 3 is arranged, so that even if only a single Y-axis crossbeam 2 is provided, it is possible to ensure that the center of gravity of the transported workpiece is located at the Z-axis vertical beam 3, thereby achieving the moment balance of the single Y-axis crossbeam 2.

[0022] Specifically, the present embodiment further includes a slide saddle 21 , two ends of the crossbeam are fixedly connected with two slide saddles 21 , and the slider 22 is fixedly connected to the corresponding slide saddle 21 .

[0023] Specifically, this embodiment also includes a rack 13, and each X-axis beam 1 is fixedly connected to a rack 13 arranged along the length direction of the X-axis beam 1, and the two racks 13 correspond to two saddles 21 respectively; the saddle 21 is rotatably connected to a gear 23 that meshes with the rack 13 corresponding to the saddle 21.

[0024] The gear 23 can provide power for the movement of the Y-axis beam 2 on the two X-axis beams 1. Specifically, a motor connected to the gear 23 is provided on the saddle 21.

[0025] Specifically, each saddle 21 is provided with two gears 23 , and the two gears 23 are arranged along the length direction of the rack 13 . More specifically, the gears 23 are provided at the bottom of the rack 13 .

[0026] Through the setting of the gear 23, when the center of gravity of the workpiece is located at the Z-axis vertical beam 3, the gear 23 and the rack 13 only need to bear the horizontal force. When the center of the workpiece deviates from the Z-axis vertical beam 3, the gear 23 and the rack 13 can generate a vertical force to balance the overturning moment caused by the deviation of the center of gravity of the workpiece.

[0027] Specifically, the present embodiment also includes a gripping mechanism, which is arranged at the bottom of the Z-axis vertical beam 3 for gripping the workpiece; the gripping mechanism includes a gripping plate 4 and a clamping assembly, the gripping plate 4 is arranged at the bottom of the Z-axis vertical beam 3 and the gripping plate 4 can rotate around an axis parallel to the X-axis horizontal beam 1 and parallel to the Y-axis horizontal beam 2; the clamping assembly is arranged at the bottom of the gripping plate 4 and is used to clamp the workpiece.

[0028] Specifically, a first rotating block 61 and a second rotating block 62 are provided at the bottom of the Z-axis vertical beam 3. The first rotating block 61 is rotatably connected to the bottom of the Z-axis vertical beam 3 and rotates around an axis parallel to the Y-axis horizontal beam 2; the second rotating block 62 is rotatably connected to the bottom of the first rotating block 61, and the second rotating block 62 rotates around an axis parallel to the X-axis horizontal beam 1.

[0029] By setting the first rotating block 61 and the second rotating block 62, when the center of gravity of the workpiece is offset from the Z-axis vertical beam 3, the center of gravity of the workpiece after the offset can be adjusted by rotating the first rotating block 61 and the second rotating block 62, so that the center of gravity after the offset can be rotated back to the Z-axis vertical beam 3.

[0030] Specifically, the clamping assembly includes two clamping plates, the two clamping plates are perpendicular to the Y-axis beam 2, and the two clamping plates are close to or away from each other along the length direction of the Y-axis beam 2 to achieve clamping and loosening of the workpiece.

[0032] When the center of gravity of the workpiece is offset from the Z-axis vertical beam 3, the center of gravity of the workpiece can be adjusted to directly below the Z-axis vertical beam 3 by rotating the first rotating block 61 and the second rotating block 62. During this process, the grab plate 4 will have four corners with different heights due to rotation, and in the subsequent process of the Y-axis crossbeam 2 driving the workpiece to move, since the first rotating block 61 and the second rotating block 62 can rotate freely, the workpiece will also swing due to the influence of the moving speed, etc., and through the arrangement of four winches 51 and pull ropes 52, when the grab plate 4 rotates with the workpiece, the winch 51 can adjust the length of the unwound pull rope 52 at any time according to the height of the corresponding angle of the grab plate 4, so that when the rotation of the workpiece is completed, the pull ropes 52 at the four corners of the grab plate 4 are in a tensioned state, so that the tension of the four pull ropes 52 ensures that the workpiece is not prone to swinging during movement.

[0033] Specifically, a tension sensor is provided at one end of the pull rope 52 connected to the grab plate 4. Through the setting of the tension sensor, the winch 51 can adjust the unwinding length of the pull rope 52 at any time according to the tension data detected by the tension sensor, so that the pull rope 52 is kept taut at any time.

[0034] Specifically, a limiting groove 31 is provided in the Z-axis vertical beam 3, and a limiting block 7 capable of vertically sliding in the limiting groove 31 is provided in the limiting groove 31.

[0035] By setting the limit block 7, during the process of grabbing the workpiece and adjusting the center of gravity of the workpiece to be directly below the Z-axis vertical beam 3 by rotating the first rotating block 61 and the second rotating block 62, the limit block 7 is located at the bottom of the limit groove 31; after the center of gravity of the workpiece is adjusted, the support plate 5 is driven by the cylinder to move upward as a whole, so that the gravity of the workpiece is applied to the cylinder and the winch 51, thereby reducing the gravity applied to the first rotating block 61 and the second rotating block 62, and preventing the rotation of the first rotating block 61 and the second rotating block 62 from becoming insensitive due to long-term gravity squeezing.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
