Topological parallel structure-based jack stabilizing and supporting device

Abstract

The invention relates to a topological parallel structure-based jack stabilizing and supporting device. The topological parallel structure-based jack stabilizing and supporting device comprises a bottom plate, a jack and a parallel mechanism; a circular groove is formed in the central part of the bottom plate; the jack is placed in the circular groove; the parallel mechanism is positioned on the outside of the jack; a lifting mechanism is mounted at the right end of the jack; a stabilizing mechanism is mounted on each of the front side and the rear side of the left end of the jack; each stabilizing mechanism comprises a stabilizing rotating rod, a stabilizing inserting rod and a connecting pin shaft; and a bearing block is arranged at the top of the jack. According to the topological parallel structure-based jack stabilizing and supporting device, the problems that the jack cannot be supported when the jack bears, a lifting action of the jack is performed in a hand rocking mode, the jack can skew when an object is heavy, the jack cannot fit the objects with different bottom surface structures and the like in the use of the jack can be solved; and the function of stabilizing and supporting the jack when the jack is subjected to the lifting action can be realized.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a jack stabilizing support device based on a topological parallel structure. Background technique [0002] A hydraulic jack refers to a jack that uses a plunger or a hydraulic cylinder as a rigid jack. It has the characteristics of compact structure, stable operation, large supporting force, and self-locking. The hydraulic jack is composed of oil chamber, oil pump, oil storage chamber, piston, crank handle, oil valve and other components. When in use, the crank handle is manually reciprocated. , so that the manual oil pump continuously presses oil into the oil cylinder. Due to the continuous increase of oil pressure in the oil cylinder, the piston and the weight on the piston are forced to move upward together, and the oil return valve is opened, and the high-pressure oil in the oil cylinder will flow back to the oil storage chamber. So the weight and the piston will fall together...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a jack stabilizing support device based on a topological parallel structure, which can solve the problem that the existing jack cannot be supported when the jack is supported, and the hand crank is used when the jack is lifted. When the object is heavy, the jack will be skewed, and the jack cannot fit objects with different bottom structures. It can realize the function of stably supporting the jack when it is lifted, and can support it when it is supported by the jack. , When the jack is lifted, it is carried out by hand or foot, when the object is heavy, the jack will not be skewed, and the jack can fit objects with different bottom structures, etc.
