These devices can significantly improve work efficiency, reduce manual labor intensity, and ensure operational safety.

[0003] CN216783494U discloses a steel structure component transfer device, including a railcar. The railcar has a swivel groove on both its front and back sides near the center. A locking slot is formed on the outer side of the swivel groove near the front end. A stopping mechanism is installed inside the swivel groove near the rear end. An adjustment mechanism is installed on the top surface of the railcar near the center. The stopping mechanism includes a support column, a locking plate on the bottom surface of the support column, and a rotating shaft on one side of the support column near the top. The swivel groove penetrates the front and bottom surfaces of the railcar. This steel structure component transfer device has good transport capabilities for steel structure components, the function of adjusting the direction of the steel structure components, facilitating changes in the direction of the steel structure components on the railcar, saving time and effort, and the function of stopping the railcar to ensure it remains stationary on the track, facilitating the loading of steel structure components.

[0013] This utility model provides a steel structure component transfer device, which has the following advantages:

[0014] (1) In this utility model, by pulling the moving rod, the moving rod moves inside the positioning hole and drives the limiting block to move inside the slide groove. When the limiting block moves, it squeezes the first spring and disengages from the inside of the limiting hole. At this time, the rotating ring disengages from the limiting position. The turntable is rotated, and the turntable drives the tubular steel structure component to rotate to adjust its direction. The rotation of the turntable drives the rotating rod to rotate inside the movable cavity. The rotation of the rotating rod drives the rotating ring to rotate inside the slide rail. When the direction is adjusted to a suitable position, the force on the moving rod is released, and the first spring drives the limiting block to reset by its own elastic force. The limiting block is inserted into the inside of the limiting hole to limit the turntable.

[0015] (2) By rotating the lead screw, the lead screw rotates and drives the moving block to move inside the moving slot. The movement of the moving block drives the second fixed seat to move towards the first fixed seat, thereby fixing the tubular steel structure component above the turntable. Pulling the moving plate upward, the moving plate moves inside the first fixed seat and drives the second spring to stretch. The moving plate drives the pressing block to move upward until the bottom end of the pressing block is in contact with the outer surface of the tubular steel structure component. Releasing the force on the moving plate, the second spring, without the influence of external force, relies on its own elasticity to apply a downward pulling force to the moving plate, thereby driving the pressing block to press the tubular steel structure component, further improving the stability of the tubular steel structure component above the turntable.

[0024] The rotating ring 55, which rotates inside the slide rail 54, can drive the rotating rod 52 to rotate.

[0025] Among them, the outer wall of the slide rail 54 is rotatably connected to the rotating shaft 57, the outer wall of the rotating shaft 57 is in contact with the outer wall of the rotating ring 55, the outer wall of the rotating ring 55 is provided with a limiting hole 56, the inside of the track car 1 is provided with a sliding groove 58, the sliding groove 58 passes through the inside of the slide rail 54, and the inner wall of the sliding groove 58 is slidably connected to a limiting block 59.

[0026] The movement of the rotating rod 52 can be limited by the limiting block 59, which is inserted into the limiting hole 56.

[0027] Among them, the end of the limiting block 59 away from the limiting hole 56 is fixedly connected to the first spring 510, the top of the inner side of the slide groove 58 is provided with a positioning hole 511, the inner wall of the positioning hole 511 is slidably connected to the moving rod 512, and the bottom end of the moving rod 512 is fixedly connected to the top of the limiting block 59.

[0028] By moving the moving rod 512, the movement of the moving rod 512 on the inner wall of the positioning hole 511 can drive the limiting block 59 to move inside the slide groove 58.

[0029] The turntable 53 is provided with a stabilizing mechanism 6 at its top, and a first fixed seat 61 is fixedly connected to the top of the turntable 53. A movable plate 63 is slidably connected inside the first fixed seat 61.

[0030] The stabilizing mechanism 6 can effectively fix the tubular steel structure component, thereby maintaining its stability during transportation.

[0035] This utility model provides a steel structure component transfer device, the specific working principle of which is as follows:

[0036] In use, the tubular steel structure component to be transported is placed between the second fixed seat 68 and the first fixed seat 61. Rotating the lead screw 66 causes the moving block 67 to move inside the moving groove 65. The movement of the moving block 67 causes the second fixed seat 68 to move towards the first fixed seat 61, thus fixing the tubular steel structure component above the turntable 53. Pulling the moving plate 63 upwards causes it to move inside the first fixed seat 61, stretching the second spring 62. The moving plate 63 then moves the pressing block 64 upwards until its bottom end is in contact with the outer surface of the tubular steel structure component. Releasing the force on the moving plate 63 allows the second spring 62 to exert a downward pull on the moving plate 63 due to its own elasticity, which in turn causes the pressing block 64 to press down on the tubular steel structure component, further lifting it. To ensure the stability of the component above the turntable 53, during the transfer process, if it is necessary to adjust the direction of the tubular steel structure component, pull the moving rod 512. The moving rod 512 moves inside the positioning hole 511 and drives the limiting block 59 to move inside the slide groove 58. The movement of the limiting block 59 compresses the first spring 510 and disengages from the limiting hole 56. At this time, the rotating ring 55 disengages from the limiting position. Rotate the turntable 53, and the turntable 53 drives the tubular steel structure component to rotate to adjust its direction. The rotation of the turntable 53 drives the rotating rod 52 to rotate inside the movable cavity 51. The rotation of the rotating rod 52 drives the rotating ring 55 to rotate inside the slide rail 54. When the appropriate direction is adjusted, release the force on the moving rod 512. The first spring 510 uses its own elasticity to drive the limiting block 59 to reset. The limiting block 59 inserts into the limiting hole 56 to limit the turntable 53.
