Problems solved by technology

[0003] Existing manipulators, excavators, hoisting machines, and steel grabbers, whether electric or hydraulic, have manipulators (operating claws for manipulators, buckets for excavators, and grab buckets and truck cranes for steel grabbers). The hook) usually can only swing up and down, and can open and close at most, but cannot complete the 360° free rotation around the axis of the arm, so that in the actual application process, it cannot be accurately positioned to grab the object, which brings a lot of trouble to the actual production. so much inconvenience

Abstract

Disclosed is a manipulator, which is characterized in that the invention comprises three parts: a jaw, a shaft and a beam-barrel. The jaw comprises a bracket and at least two claws. The middle parts of the two claws are hinged on the bracket whose back end is connected with the shaft. A hydraulic cylinder is respectively arranged at the rear end of the two claws. Pistons of the two hydraulic cylinders are connected with corresponding rear ends of the claws. The center of the shaft is provided with oil supplying holes which are respectively connected with the two hydraulic cylinders so as to form a lever-type grasping mechanism. The shaft is rotationally supported inside the beam-barrel. A first umbrella-shaped gear arranged on the output shaft of a hydraulic motor meshes with a second umbrella-shaped gear which is correspondingly connected on the shaft so that a rotating mechanism where the jaw can rotate around the shaft by 360 degrees is formed. The manipulator has characteristics of reasonable design, high performance price ratio, simple structure, convenient using, high work efficiency and good reliability.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a hydraulic manipulator. As an operating part, the hydraulic manipulator can be widely used in manipulators, hoisting machines, and steel grabbing machines in the construction industry and industrial and agricultural production industries. Background technique [0002] In the existing construction industry, industrial and agricultural production industries, the emergence and use of manipulators, excavators, hoisting machines, and steel grabbers have improved the degree of modernization of production, reduced labor intensity, and doubled production efficiency. [0003] Existing manipulators, excavators, hoisting machines, and steel grabbers, whether electric or hydraulic, have manipulators (operating claws for manipulators, buckets for excavators, and grab buckets and truck cranes for steel grabbers). The hook) usually can only swing up and down, and can open and close at most,...
