Abstract
Description
Technical Field
[0001] This utility model relates to a load-bearing structure applied to the connection of the detachable beam at the top of the box. This structure realizes the function of quickly disassembling and assembling the top beam of the box for loading and unloading internal equipment, and can also meet the strong shear force that the detachable beam connection can withstand when the box is hoisting heavy and large-sized internal equipment. Background Technology
[0002] Compared to detachable enclosures, integral enclosures offer significant advantages in terms of processing technology, packaging and transportation costs, and on-site installation time. This is especially true when the internal equipment is large, heavy, and difficult to disassemble repeatedly, making internal equipment loading and unloading a challenging installation issue. Loading and unloading from the side of the enclosure is cumbersome and prevents the equipment from being suspended in the air for lateral movement. Therefore, top loading and unloading is more common. To facilitate top disassembly, the top wall panels and crossbeams need to be designed as detachable structures. Detachable top crossbeams not only allow for quick loading and unloading of large, heavy internal equipment from the top after removing the top wall panels, but also solve the problem of longitudinal shear forces at the detachable beam connections affecting hoisting safety when the enclosure is hoisted short distances along with the internal equipment due to its excessive weight. Summary of the Invention
[0003] The purpose of this invention is to propose a connection structure that enables the quick assembly and disassembly of the top beam of the box body for loading and unloading internal equipment, while also meeting the requirement that the connection points of the disassembled beams can withstand strong shear forces when the box body is hoisting heavy, large-sized internal equipment.
[0004] The above objective is achieved through the following technical solution: a load-bearing structure applied to the connection of the detachable beam at the top of the box body, mainly composed of a top beam connector, a top detachable beam, a detachable beam connecting top plate, a detachable beam connecting bottom plate, a detachable beam connecting sleeve, and high-strength bolts; specifically: a through hole with a circumference 4mm larger than the outer diameter of the detachable beam connecting sleeve is opened at the end of the top detachable beam; the detachable beam connecting sleeve is passed through the hole and welded to the top detachable beam as a whole; the detachable beam connecting top plate is symmetrically welded to the already welded top detachable beam, and the welded detachable beam connection... The top plate is fitted with a hole matching the inner diameter of the detachable beam connecting sleeve; a through hole with a circumference 4mm larger than the outer diameter of the detachable beam connecting sleeve is made at the end of the top beam connector, and the detachable beam connecting sleeve is passed through the hole and welded to the top beam connector to form a whole; a gap for disassembly is left between the top beam connector and the top detachable beam, and the detachable beam connecting top plate is fitted with the hole matching the detachable beam connecting sleeve on the top beam connector; the detachable beam connecting bottom plate is arranged symmetrically at the bottom of the top beam connector and the top detachable beam, and the hole matching the detachable beam connecting sleeve is made; high-strength bolts are passed through the detachable beam connecting sleeve and tightened.
[0005] The aforementioned top beam connector and top detachable beam are both rectangular tubes with standard cross-sectional dimensions. The wall thickness and length can be selected according to the actual stress conditions, and their transverse and longitudinal yield strengths meet most load requirements.
[0006] The detachable beam connecting top plate and detachable beam connecting bottom plate are both made of commonly used thick steel plates, which serve to connect and strengthen the top beam connector and the top detachable beam node. The detachable beam connecting bottom plate is a movable connection, which meets the detachable requirement of the top beam.
[0007] The detachable beam connecting sleeve is made of stainless steel and serves to bear the longitudinal shear force of the bolts.
[0008] The high-strength bolts have much higher tensile strength and yield strength than ordinary bolts, and are often used in connection structures subjected to large shear forces. Beneficial effects
[0009] This utility model consists of a top beam connector, a detachable top beam, a detachable beam connecting top plate, a detachable beam connecting bottom plate, a detachable beam connecting sleeve, and high-strength bolts. It features low cost, wide applicability, and simple processing. Attached Figure Description
