Description

Technical Field

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] A search revealed an existing patent (publication number: CN 220996465 U) that discloses a steel structure transportation device, including a base plate and a base frame fixedly connected to the bottom outer wall of the base plate. Rollers are installed at both ends of the outer walls on both sides of the base frame. Diagonal rods are fixedly connected to both sides of the outer wall at the other end of the base plate. A gripping rod is fixedly connected between the outer walls of the diagonal rods. A placement block is fixedly connected to the top outer wall of the base plate, and grooves are formed at both ends of the top outer wall of the placement block. This invention, by placing the more fragile steel structures sequentially on top of the placement block, activates a drive mechanism that rotates two first threaded rods, thereby moving multiple clamping plates. This fixes and limits the steel structures on top of the placement block, preventing collisions and protecting them. The base frame allows for the placement and storage of other steel structures, facilitating the separate placement of different types of steel structures.

[0004] Existing steel structures are typically heavy, and manual handling requires the cooperation of multiple people or auxiliary tools, resulting in slow handling speed. In addition, manual handling is subject to physical limitations, workers are prone to fatigue, require frequent rest, and cannot work continuously and efficiently, resulting in low efficiency. Furthermore, the patent documents cited above do not propose any solutions to the above problems.

[0005] Therefore, a steel structure transportation device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] As attached Figures 1 to 4 The steel structure transportation device shown includes a transport vehicle 1. A fixed seat 15 is provided on one side of the transport vehicle 1. A drive motor 16 is provided on one side of the fixed seat 15. A lead screw 17 is connected to one side of the drive motor 16 through an output shaft. A guide rod 19 is provided at the bottom of the lead screw 17. A connecting block 18 is threaded to the outside of the lead screw 17. Two sets of connecting blocks 18 are symmetrically arranged, and a clamping frame 20 is fixedly provided at the bottom of each connecting block 18.

[0023] Among them, the drive motor 16 provides continuous and stable power, which improves efficiency compared to manual handling and can operate continuously for 24 hours without being limited by physical strength. At the same time, the lead screw 17 and the threaded rod 24 convert rotational motion into linear displacement, ensuring that the positioning error of the steel structure is small during handling and effectively avoiding the position deviation of manual placement. Example

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, a drive wheel 21 is connected to one side of the lead screw 17 via a rotating shaft. A belt 22 is sleeved on the outside of the drive wheel 21, and a driven wheel 23 is sleeved on one side of the belt 22. A threaded rod 24 is provided on one side of the driven wheel 23. Furthermore, by providing the drive wheel 21, the drive wheel 21 drives the driven wheel 23 via the belt 22, which synchronously drives the threaded rod 24 to rotate, thereby realizing the composite control of the vertical movement of the lead screw 17 and the horizontal movement of the threaded rod.

[0026] In a preferred embodiment, hydraulic cylinders 2 are symmetrically arranged at both ends inside the transport vehicle 1. A hydraulic rod 3 is sleeved on one side of the hydraulic cylinder 2, and a limit plate 5 is fixedly installed on one side of each hydraulic rod 3. Furthermore, by driving the hydraulic rod 3 through the hydraulic cylinder 2 to push the limit plate 5 to move horizontally, steel structures of different specifications can be fixed to prevent displacement caused by bumps during transportation.

[0027] In a preferred embodiment, telescopic rods 4 are fixedly provided at both ends of the limiting plate 5, and the bottom of the limiting plate 5 is fitted and connected to the support frame 6; furthermore, by providing telescopic rods 4, the limiting plate 5 is provided with guiding support, so as to avoid the hydraulic rod 3 being subjected to force eccentricity, and to ensure that the limiting plate 5 and the support frame 6 are fitted tightly and the parallelism error is small when clamped.

[0028] In a preferred embodiment, the support frame 6 is slidably connected to the transport vehicle 1, and three sets of support frames 6 are equally spaced. Furthermore, by providing support frames 6, the position can be adjusted according to the length of the steel structure, and different specifications of components can be carried in sections, thereby improving loading efficiency and stability.

[0029] In a preferred embodiment, the transport vehicle 1 is connected to the connecting frame 7 at both ends by support columns. The bottom ends of the connecting frame 7 are symmetrically provided with mounting seats 8. An electric push rod 9 is fixedly provided on one side of the mounting seat 8. A slider 10 is fixedly provided on one side of the electric push rod 9, and the slider 10 is fitted into the mounting seat 8. Furthermore, by providing the electric push rod 9, the electric push rod 9 pushes the slider 10 to slide up and down in the mounting seat 8 to adapt to the gripping of steel structures of different heights.

[0030] In a preferred embodiment, a micro motor 11 is provided on one side of the mounting base 8. A rotating shaft 12 is connected to one side of the micro motor 11 via an output shaft. The rotating shaft 12 passes through the slider 10 and is connected to a connecting roller 13. A rope 14 is connected around the outer wall of the connecting roller 13, and a fixed seat 15 is fixedly provided on one side of the rope 14. Furthermore, the connecting roller 13 is driven by the micro motor 11 to retract and extend the rope 14, thereby pulling the fixed seat 15 to move horizontally. This, in conjunction with the electric push rod 9, enables the fixed seat 15 to be precisely positioned in three-dimensional space.

[0031] The working process of this utility model is as follows:

[0032] First, the drive motor 16 is used as the power source, driving the lead screw 17 to rotate through the output shaft, converting the rotational motion of the motor into the axial linear motion of the lead screw 17. The connecting block 18 outside the lead screw 17 engages with the lead screw 17 through a threaded pair. When the lead screw 17 rotates, the connecting block 18 moves up and down along the axis of the lead screw 17. The guide rod 19 is set parallel to the bottom of the lead screw 17, passing through the connecting block 18, restricting the radial movement of the connecting block 18, ensuring that it moves along a straight trajectory, and preventing the steel structure from shaking during transportation. One side of the lead screw 17 is connected to the drive wheel 21 through a rotating shaft, and the drive wheel 21 is driven by a belt 22. The driven wheel 23 rotates, which in turn drives the threaded rod 24 on one side of the driven wheel 23 to rotate. The clamping frame 20 at the bottom works in conjunction to improve the stability of the steel structure during handling. At the same time, the speed and start / stop of the drive motor 16 are controlled by a program, and the moving speed and stroke of the lead screw 17 can be adjusted. In conjunction with the belt drive system 22, the steel structure can achieve compound movement of the lead screw 17 in the vertical direction and the threaded rod 24 in the horizontal direction, accurately positioning it to the target position on the transport vehicle 1. The hydraulic cylinders 2 at both ends inside the transport vehicle 1 drive the hydraulic rods 3 to extend and retract, causing the limit plate 5 to move in the horizontal direction. The telescopic rods 4 at both ends of the limit plate 5 lift... The support guides and prevents the limit plate 5 from shifting, ensuring its bottom fits snugly against the support frame 6. Hydraulic pressure clamps the steel structure placed on the support frame 6, preventing swaying during transport. Three equally spaced support frames 6 are slidably connected to the transport vehicle 1, allowing for position adjustment based on the steel structure length. This allows for zoned support of components of different specifications, improving loading efficiency and stability. Furthermore, the connecting frames 7 at both ends of the transport vehicle 1 are fixed by support columns. An electric push rod 9 within the bottom mounting base 8 pushes the slider 10 up and down, adjusting the vertical height of the fixed base 15. This structure allows the drive motor 16 and lead screw 17 assembly to move up and down. The system is flexible and adaptable to different heights of steel structures being gripped or loaded onto the transport vehicle 1. Additionally, a micro motor 11 on one side of the mounting base 8 drives the rotating shaft 12 and connecting roller 13 to rotate, releasing and retracting the rope 14 to move the fixed base 15. Combined with the vertical adjustment of the electric push rod 9, the fixed base 15 can be finely adjusted in three-dimensional space, allowing the clamping frame 20 to be precisely aligned with the target area on the steel structure or transport vehicle 1. Automated handling and transportation ensure accurate positioning of the steel structure during handling, avoiding positional deviations during manual handling. At the same time, workers do not need to directly contact the heavy objects, avoiding risks such as crushing or squeezing during handling.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
