Abstract

The invention discloses a synchronizing mechanism for a heavy manipulator and belongs to the field of mechanical hoisting. The synchronizing mechanism mainly solves the problem of shifting of the gravity center of the heavy manipulator during operation and comprises a centering support rod, a centering mandrel, a first side support rod and a second side support rod. The first side support rod and a second side support rod are symmetrically arranged, two horizontal ends of the centering support rod are fixed on a main framework of the heavy manipulator, a perpendicular through hole is arranged in the middle of the centering support rod, the centering mandrel is slidably and penetratingly sleeved in the perpendicular through hole, the lower end of the centering mandrel is hinged with one ends of the first side support rod and the second side support rod simultaneously, and the other ends of the first side support rod and the second side support rod are respectively hinged to a left clamp arm and a right clamp arm of the heavy manipulator. By the aid of the synchronizing mechanism for the heavy manipulator, the gravity center of the heavy manipulator can keep unchanged, the left clamp arm and the right clamp arm of the heavy manipulator move synchronously, and a hoisting effect is guaranteed.

Description

The heavy-duty machinery hand is used synchronizer gear
Technical field
The present invention relates to a kind of lifting machine device, specifically is that a kind of heavy-duty machinery hand is used synchronizer gear.
Background technology
The heavy-duty machinery hand is a kind of mechanical device of hoisting large-size machinery and equipment; It is made up of lifting crossbeam, the first main framing plate, the second main framing plate, first group of manipulator and second group of manipulator; Each group manipulator has the left clamp arm of comprising, right clamp arm, and the top of left clamp arm, right clamp arm is connected with unsettled hydraulic ram.Because every group of manipulator only depends on the middle part of left clamp arm, right clamp arm to be connected with the main framing plate of heavy-duty machinery hand; Therefore have an effect when hydraulic ram and be; The center of gravity of every group of manipulator is squinted; Thereby left and right pincers pin and the dynamics that compresses that needs the lifting machinery and equipment are differed, influence lifting effect.
Summary of the invention
The object of the present invention is to provide a kind of heavy-duty machinery hand to use synchronizer gear; This heavy-duty machinery hand synchronizer gear can make manipulator when hydraulic ram is had an effect, keep center of gravity constant; Left clamp arm, right clamp arm are synchronized with the movement; Thereby make left and right pincers pin and need the lifting machinery and equipment to compress dynamics identical, ensure the lifting effect.
For addressing the above problem; The present invention adopts following technical scheme: the heavy-duty machinery hand is used synchronizer gear; It is characterized in that; Comprise the centering strut, to center shaft, the symmetrically arranged first side strut bar and the second side strut bar, said centering strut is the level of state and two ends are fixed on the main framing of heavy-duty machinery hand, said centering strut middle part is provided with the vertical through hole of above-below direction; Said center shaft is slidably passed is nested with in said vertical through hole; And said simultaneously hinged with an end of the said first side strut bar and the second side strut bar to the center shaft lower end, the other end of the said first side strut bar and the second side strut bar is hinged on respectively on the left clamp arm and right clamp arm of heavy-duty machinery hand, like this when left clamp arm and right clamp arm open or close up; Center shaft can be slided up and down in vertical through hole in this synchronizer gear makes that manipulator can pulsation-free work.
Said lower end to center shaft is provided with a cross bar, and integral body is inverted T-shape, and said cross bar two ends are arranged with and the first side strut bar and the second side strut bar pivotally attached connecting bore.
The invention has the beneficial effects as follows: can make manipulator when hydraulic ram is had an effect, keep center of gravity constant, left clamp arm, right clamp arm are synchronized with the movement, thereby make left and right pincers pin and need the lifting machinery and equipment to compress dynamics identical, ensure the lifting effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:
Fig. 1 is a main TV structure scheme drawing of the present invention;
Fig. 2 is a running condition scheme drawing of the present invention.
Among the figure: 1 centering strut, 11 vertical through hole, 2 pairs of center shafts, 3 first side strut bars, 4 second side strut bars, 5 main framing plates, 6 left clamp arms, 7 right clamp arms.
The specific embodiment
Like Fig. 1, shown in Figure 2; The heavy-duty machinery hand is used synchronizer gear; Comprise centering strut 1, to center shaft 2, the symmetrically arranged first side strut bar 3 and the second side strut bar 4, centering strut 1 middle part is provided with the vertical through hole 11 of above-below direction, the two ends of centering strut 1 are fixed on the main framing plate 5 of heavy-duty machinery hand; Centering strut 1 is the level of state; One end of center shaft 2 is upward through vertical through hole 11 and can in this vertical through hole 11, slides up and down, and to cross bar of center shaft 2 other ends welding, the cross bar two ends are arranged with and the first side strut bar 3 and the second side strut bar, 4 pivotally attached connecting bores; This connecting bore is hinged with an end of the first side strut bar 3 and the second side strut bar 4 respectively, and the other end of the first side strut bar 3 and the second side strut bar 4 is hinged on respectively on the left clamp arm 6 and right clamp arm 7 of heavy-duty machinery hand.
Working process: when the heavy-duty machinery hand brings into operation; The lower end that heavy-duty machinery left and right tong arm on hand drives the first side strut bar 3 and the second side strut bar 4 respectively is to two lateral movements; The upper end that drives the first side strut bar 3 and the second side strut bar 4 simultaneously moves downward; Thereby drive center shaft 2 is moved downward, and since 1 pair of qualification effect of centering strut to center shaft 2 make and can only move up and down and can not sway center shaft 2, thereby left clamp arm, right clamp arm are synchronized with the movement.
The above; Principles more of the present invention just explain through diagrams; This specification sheets be not be to the present invention be confined to shown in described concrete structure and the Applicable scope, so every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
Except that the said technical characterictic of specification sheets, all the other technical characterictics are those skilled in the art's known technology.
