Description

Technical Field

[0001] This utility model relates to heavy T-beams in the field of lifting, and in particular to a non-slip pneumatic hook-clamping device. Background Technology

[0002] There are several methods for gripping and assembling T-beams during shipbuilding. One common method is based on a gantry and its attached devices. The gantry can move in the X, Y, and Z directions with the attached devices. Multiple gripping devices are connected to the attached devices. Once the gripping devices are moved to the designated position, compressed air is used as a power source to drive the pneumatic motor on the gripping device. The motor rotates through a lead screw, causing the connected clamping components to shift and clamp the web of the T-beam for assembly. The disadvantage of this method is that the clamping force output by the clamps is limited. When frequently gripping heavy T-beams, the contact points between the clamps and the heavy T-beams wear out quickly, making slippage likely and affecting the assembly quality of the heavy T-beams and the overall construction progress. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies and address the problem of slippage during the gripping of heavy T-beams, which affects the assembly quality and overall construction progress, this application provides an anti-slip pneumatic hook-and-clamp gripping device. This device grips heavy T-beams using a combination of hook plates and clamps, leveraging the structural characteristics of the heavy T-beams to complete the gripping operation while preventing slippage, thus solving the technical problem of T-beam slippage.

The hook clamp assembly is located in the middle of the lower part of the base plate, with symmetrically linked hook plates forming a clamping structure. The arc-shaped hooks at the ends of the hook plates act on the heavy T-beam panel to lift the heavy T-beam. The clamp assembly is located below the base plate and has a pneumatic clamp for clamping the web of the heavy T-beam. The hook-and-clamp assembly and the clamp assembly work together. The hook plate of the hook-and-clamp assembly hooks onto the lower surface of the panel of the heavy T-beam and lifts the heavy T-beam. The clamp of the clamp assembly clamps the web of the heavy T-beam.

[0005] In order to further solve the technical problems to be solved by the embodiments of this application, the hook and pliers assembly provided in the embodiments of this application includes a hook plate base, a cylinder lifting base, a cylinder lifting device and a hook plate; The upper end of the hook plate base is connected to the bottom plate of the vertical beam and is hoisted onto the bottom plate of the vertical beam; the cylinder lifting base is fixed by connecting the lower end of the hook plate base; the cylinder lifting device is installed on the cylinder lifting base and connected to the intermediate bearing base above; the hook plate consists of two groups of four strip plates installed on both sides of the clamp, each strip plate is connected by a pin, and each group is connected by two shafts, the upper and lower shafts pass through the intermediate bearing base and the cylinder lifting base respectively, and the ends of the strip plates have arc-shaped hooks to form a symmetrical clamping mechanism; The cylinder lifting device extends and retracts the traction hook plate, and the arc-shaped hook plate hooks onto the lower surface of the panel of the heavy T-beam, lifting the heavy T-beam.

[0006] Furthermore, the clamp assembly includes a slide, a clamp, and a pneumatic motor; The slide rail is hoisted on the lower surface of the vertical beam bottom plate and arranged in parallel; the clamp includes a slider, a lead screw and a jaw; the slider is assembled on the slide rail and slides along it; the slider has an internal thread that is screwed to the lead screw, which is set on the lower surface of the vertical beam bottom plate and driven by a pneumatic motor; the upper part of the jaw is connected to the slider and the lower part has a clamping jaw for contacting the web of the heavy T-beam. The two ends of the lead screw have opposite helical directions and are respectively screwed to sliders. The grippers are set opposite to each other. When the pneumatic motor drives the lead screw to rotate, the grippers slide along the slide and clamp the web of the heavy T-beam.

[0007] Positive effects: The technical solutions provided in this application embodiment have at least the following technical effects or advantages: Because this embodiment of the application uses a hook-and-clamp assembly to lift the heavy T-beam through the arc-shaped hook of the hook plate, and a clamp assembly to clamp the web of the heavy T-beam through a pneumatic clamp, the hook plate and the pneumatic clamp work together to grip the heavy T-beam, effectively solving the technical problem of slippage of the heavy T-beam in the prior art, meeting the assembly requirements of the heavy T-beam, and thus achieving the technical effect of avoiding slippage during the gripping of the heavy T-beam.
