Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary structures for steel hoisting, and more specifically, it relates to a large multi-axis lifting device for steel hoisting. Background Technology

[0002] In the steel production, processing, assembly and transportation industry, steel hoisting is an essential part. Traditional steel hoisting equipment has a relatively simple structure, usually adopting a single-shaft or double-shaft design, and using hooks or clamps to hoist steel. However, with the expansion of steel production scale and the increasing diversification of steel specifications and shapes, traditional hoisting equipment has gradually exposed many problems.

[0003] Based on the above, most existing lifting tools have poor applicability. For large, extra-long, extra-wide, or irregularly shaped steel, single-axis or double-axis lifting tools cannot achieve uniform force distribution, which can easily lead to the steel tilting, deforming, or even falling off during the lifting process. Due to the large weight and strong inertia of the steel itself, the instability of the steel will increase the impact on the lifting tool structure, shorten the service life of the lifting tool, and also increase the operational risks for operators. When lifting steel of different specifications, complex manual adjustments are required, and even the replacement of some parts are necessary. The operation is cumbersome and time-consuming, which seriously affects the work efficiency of steel lifting. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a large multi-axis lifting device for steel hoisting. This addresses the issue of poor applicability of most lifting devices. For large, extra-long, extra-wide, or irregularly shaped steel, single-axis or double-axis lifting devices struggle to achieve uniform force distribution, easily leading to tilting, deformation, or even detachment of the steel during hoisting. Due to the large weight and high inertia of the steel, its instability increases the impact on the lifting device structure, shortens its service life, and increases the operational risks for operators. When hoisting steel of different specifications, complex manual adjustments and even replacement of parts are required, making the operation cumbersome, time-consuming, and severely impacting the efficiency of steel hoisting work.

[0005] This utility model relates to a large multi-axis lifting device for steel hoisting, achieved through the following specific technical means:

[0006] The core components of a large multi-axis lifting device used for steel hoisting include the following parts: lifting device carrier, load-bearing base, lifting support shaft, and stabilizing support.

[0007] The lifting device carrier has a load-bearing side seat fixedly installed on its side. Assembly openings are provided on the sides of the lifting device carrier and the load-bearing side seat. A positioning groove is provided on the top of the lifting device carrier, and a positioning support frame is fixedly installed on the side of the positioning groove. The load-bearing base is located at the bottom of the lifting device carrier. A reinforcing side seat is fixedly installed on the side of the load-bearing base. Threaded supports are fixedly installed on the sides of the load-bearing base and the reinforcing side seat. A threaded support block is sleeved on the outside of the threaded support. A locking opening is provided on the side of the threaded support, and a locking bolt is provided inside the locking opening. The lifting support shaft is fixedly installed at the bottom of the lifting device carrier. An assembly shaft groove is provided on the side of the lifting support shaft, and a hanging shaft collar is sleeved inside the assembly shaft groove. The stabilizing support is located at the bottom of the lifting support shaft, and a threaded support column is fixedly installed on the top of the stabilizing support.

[0008] Furthermore, the top of the lifting device carrier is also provided with a mounting side seat and a guide shaft; the mounting side seat is fixedly installed on the top of the lifting device carrier, and the guide shaft is rotatably disposed on the side of the mounting side seat.

[0009] Furthermore, the side of the load-bearing base is also provided with a reinforcing ring and a reinforcing support; the reinforcing ring is fixedly sleeved on the outside of the load-bearing base, and the reinforcing support is fixedly installed on the outside of the load-bearing base.

[0010] Furthermore, the side of the lifting support shaft is also provided with a threaded groove and a limiting opening; the threaded groove is opened at the bottom end of the lifting support shaft, and the limiting opening is opened inside the assembly shaft groove.

[0011] Furthermore, the side of the hanging collar is also provided with a limiting groove, a limiting bolt, a lifting side block, and a lifting cylinder; the limiting groove is opened on the side of the hanging collar, the limiting bolt is set inside the limiting groove, the lifting side block is fixedly installed on the side of the hanging collar, and the lifting cylinder is fixedly installed on the side of the lifting side block.

[0012] Furthermore, the bottom of the stabilizing support is also provided with an adjusting support frame, an adjusting grip groove, a rotating support frame, and a supporting ball; the adjusting support frame is fixedly sleeved on the outside of the stabilizing support, the adjusting grip groove is opened on the side of the adjusting support frame, the rotating support frame is fixedly installed at the bottom of the stabilizing support, and the supporting ball is rotatably set on the inside of the rotating support frame.

[0013] The large multi-axis lifting device for steel hoisting provided by this utility model has the following beneficial effects:

[0014] This utility model achieves the following optimization effects by providing a lifting device carrier, a load-bearing base, a lifting support shaft, and a stabilizing support:

[0015] The positioning slot and positioning support frame are precisely matched and firmly connected to the lifting equipment via the lifting cable to form a reliable lifting foundation. The lifting carrier seat ensures that the load-bearing base is firmly installed by means of the precise fit between the assembly opening and the threaded support. The threaded support block combined with the locking bolt realizes double limit locking of the threaded support, which significantly improves the structural stability.

[0016] In terms of lifting angle adjustment, the limiting opening and limiting bolts provide three-dimensional limiting support for multiple sets of hanging shaft rings, so that the hanging shaft rings and the lifting side blocks can work together to adjust the tilt angle of the lifting cylinder, achieving a flexible adjustment of 360 degrees in the lifting direction, perfectly adapting to the multi-angle binding needs of large, extra-long, extra-wide and irregularly shaped steel.

[0017] To ensure stability during hoisting, the user-friendly design of the adjustable support frame and adjustable grip allows for precise control of the rotation angle of the stable support via the threaded support column. Combined with the support ball, it provides dynamic positioning support for the top of the steel, effectively counteracting swaying and offset during hoisting. This ensures the stability of heavy-duty steel throughout the lifting and transportation process, significantly improving operational safety and efficiency. Attached Figure Description
