Lotus claw for grabbing waste steel

Abstract

The invention relates to the technical field of mechanical arm equipment, and discloses a lotus claw for grabbing waste steel, the lotus claw comprises a connecting table fixedly connected with a mechanical arm, a hydraulic rod communicated with a hydraulic device and a grabbing flap hinged to the connecting table, the grabbing flap is composed of an upper flap and a tip end, and the upper flap is hinged to the tip end. According to the lotus claw for grabbing the waste steel, through two-section operation, the driving angle of the hydraulic rod is always at the optimal angle, meanwhile, lever amplification of acting force is achieved, under the same hydraulic oil pressure, the grabbing force is larger, harder objects can be crushed, heavier goods can be grabbed, meanwhile, the overall stress is reduced, and the grabbing efficiency is improved. The load of each part is smaller, the service life is longer, secondly, when the upper petal is driven to rotate, the driving point is close to the root of rotation, the higher running speed is achieved, after an object is grabbed, the driving point is close to the bottom, the larger driving force is achieved, and the running speed and the acting force are kept in the optimal state.

Description

technical field [0001] The invention relates to the technical field of manipulator equipment, in particular to a lotus grasper used for grasping scrap steel. Background technique [0002] The lotus grab, also known as the steel grab machine, is designed for grabbing loose or massive materials such as stones, scrap metal, and household garbage. It drives the grab flaps through hydraulic pressure to realize opening and closing to grab materials. [0003] One of the more important functions of the lotus grab is to break large pieces of hard materials. For example, in the car dismantling field, it is often seen that the lotus grab is used to grab the car, and then shake it back and forth to tear the car apart. , a larger gripping force is needed to ensure that the car can be firmly grasped, and it will not fall when it is shaken. In fact, the gripping force is a relatively important indicator to measure the quality of the lotus, and the gripping force is average. Subject to hyd...

Problems solved by technology

[0004] Further, subject to the driving direction of the hydraulic rod and the position of the hinge point, on the one hand, the direction from the hinge point to the fulcrum is usually not perpendicular to the hydraulic cylinder, that is, the force is not perpendicular to the "lever", and the maximum torque cannot be achieved, which restricts the grasping force, on the other hand, the position of the hydraulic lever is usually located in the middle of the gripper flap, and there is no sufficient extension of the moment arm, which limits the moment

[0005] Furthermore, the hinge point of the hydraulic rod and the grasping flap is close to the root, which can bring a faster grasping speed, but reduces the grasping force, and close to the bottom, although a greater grasping force is achieved, it limits the grasping force. Speed, the existing equipment is comprehensively considered, but both are limited
