Description

Technical Field

[0001] The invention relates to the technical field of hoisting, in particular to a trapezoidal shoulder beam device for safely lifting a steel structure. Background Art

[0002] Cable hoisting is a common construction hoisting technique. It typically involves two cables connected directly to a steel beam, with the bottom of the beam attached to the structure being hoisted. Existing structures typically have fixed lifting points. If the structure being hoisted has an irregular shape or a significant center of gravity offset, it can easily shift during the hoisting process, failing to meet construction requirements.

[0003] For example, the Chinese utility model patent application publication number CN214733819U discloses an adjustable lifting pole beam device in the field of lifting equipment related technology, comprising a pole beam body and a main lifting plate. The main lifting plate is integrally provided on the upper side of the pole beam body, and side lifting hooks are welded and fixed on both sides of the pole beam body. The side lifting hooks on both sides of the pole beam body are symmetrically arranged at equal intervals, and a pole beam support main plate is provided in the middle of the pole beam body. The hooks of the pole beam body of the utility model are mounted on an adjustable sliding block. The position of the adjustable sliding block on the pole beam body can be adjusted as needed, and the distance between the two hooks can be adjusted to meet the lifting requirements of products of different lengths and sizes. It has a wide range of uses. The side lifting hooks are welded and fixed on both sides of the pole beam body, and multiple groups of small-sized and light-weight products can be lifted simultaneously. The multi-hook structural design can effectively improve the lifting efficiency. However, when this solution is applied to structures with irregular shapes and serious center of gravity shift, it is still prone to shifting and cannot meet construction requirements.

[0004] Therefore, there is an urgent need for a trapezoidal shoulder beam device for safely lifting steel structures to solve existing construction difficulties. Summary of the Invention

[0005] In order to avoid the above problems existing in the prior art, the purpose of the present invention is to provide a trapezoidal shoulder beam device for safely lifting a steel structure.

[0012] The present invention is further configured such that the trapezoidal shoulder beam device for safely lifting a steel structure also includes a connecting clamp, which is arranged at the bottom of the lower beam and is used to connect to the hoisted structure.

[0013] The present invention is further configured such that a plurality of mounting holes are provided at the bottom of the lower beam along the length direction for mounting the connecting clamp.

[0014] The present invention is further configured such that if the center of gravity of the hoisted structure shifts close to the anchor point adjustment device on one side, causing the hoisting main beam to tilt, the anchor point adjustment device on that side drives the anchor point slider to retract, and the cable winch on that side synchronously releases the cable; the anchor point adjustment device on the other side drives the anchor point slider to extend, and the cable winch on the other side synchronously retracts the cable until the hoisting main beam is balanced again.

[0015] During actual adjustment, the hoisting state is divided according to the inclination angle measured by the level meter, and graded control is performed according to the hoisting state. In this embodiment, the following divisions are made according to the inclination angle: When the inclination angle θ is 0°-0.3°, it is determined to be within the safe range and no adjustment is required; When the inclination angle θ is 0.3°-1°, it is judged as a slight tilt, and the hydraulic cylinder and cable winch are synchronously extended or retracted at a speed of 5mm / s-10mm / s.

[0019] The present invention is further configured such that the trapezoidal shoulder beam device for safe lifting of steel structures further includes a control module, and the control module is electrically connected to the anchor point adjustment device, the cable winch and the spirit level respectively.
