Suspension arm strength detection structure applied to engineering machinery production

Abstract

The invention discloses a suspension arm strength detection structure applied to engineering machinery production. The structure comprises a bottom plate, a hydraulic rod, a first spring, a rope, a lifting hook, a second spring and limiting blocks, a first groove is formed in the upper surface of the bottom plate; a first spherical roller is movably mounted in the first groove; a second groove isformed in the inner wall of the first groove in the bottom plate; a second spherical roller is movably mounted in the second groove, a base is placed above the first spherical roller, a bearing cylinder is fixedly arranged above the base, inner cavities are formed in the bearing cylinder and the base, hydraulic rods are fixed in the inner cavities through bolts, and connecting blocks are fixedly mounted above the hydraulic rods. According to the suspension arm strength detection structure applied to engineering machinery production, the whole device can be conveniently moved during detection,the stress of the lifting hook during detection can be adjusted, and the stress of the lifting hook can be adjusted in real time, so that a better detection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of construction machinery production, in particular to a structure for detecting the strength of a boom used in construction machinery production. Background technique [0002] Common construction machinery are cranes, excavators, and drilling rigs. The main purpose of such machinery is to provide convenience during the construction process. Compared with direct use of manpower, construction machinery used in the construction process can greatly improve construction efficiency and can also handle Some tasks that cannot be achieved by manpower, such as impacting and breaking concrete layers, lifting reinforced concrete objects, and drilling down, can replace manpower and improve construction efficiency. [0003] A crane is usually composed of a mechanical boom and multiple hydraulic cylinders. The hook lock at the front end of the device is stretched through the telescopic boom, so that the cargo can be lifte...
