Abstract

The utility model discloses a synchronizing mechanism for a heavy-duty manipulator, belongs to the field of mechanical lifting, and mainly solves the problem that the gravity center of the heavy-duty manipulator shifts during running. The mechanism comprises a centering support rod, a centering mandrel, and a first side support rod and a second side support rod which are symmetrically arranged, wherein the two horizontal ends of the centering support rod are fixed on a main framework of the heavy-duty manipulator; a vertical through hole is formed in the middle of the centering support rod; the centering mandrel slidably passes through and is sleeved in the vertical through hole; the lower end of the centering mandrel is hinged with one end of the first side support rod and one end of 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 tong arm and a right tong arm of the heavy-duty manipulator. By the mechanism, the gravity center of the manipulator can be kept unchanged during running, the left tong arm and the right tong arm synchronously move, and a lifting effect is ensured.

Description

The heavy mechanical hand synchronizer gear
Technical field
The utility model relates to a kind of lifting mechanical device, specifically a kind of heavy mechanical hand synchronizer gear.
Background technology
Heavy mechanical hand is a kind of mechanical device of hoisting large-size machinery and equipment, it is comprised of lifting cross beam, the first main framing plate, second main rib frame 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 mechanical hand, therefore have an effect when hydraulic ram and be, the center of gravity of every group of manipulator is offset, thereby left and right pincers pin and the compression dynamics that needs the lifting machinery and equipment are differed, impact lifting effect.
The utility model content
The purpose of this utility model is to provide a kind of heavy mechanical hand synchronizer gear, this heavy mechanical hand synchronizer gear can make manipulator keep center of gravity constant when hydraulic ram is had an effect, left clamp arm, right clamp arm are synchronized with the movement, thereby make left and right pincers pin identical with the compression dynamics that needs the lifting machinery and equipment, ensure the lifting effect.
For addressing the above problem, the utility model is by the following technical solutions: the heavy mechanical hand synchronizer gear, it is characterized in that, comprise the centering strut, to center shaft, symmetrically arranged the first side strut bar and the second side strut bar, described centering strut is the level of state and two ends are fixed on the main framing of heavy mechanical hand, described centering strut middle part is provided with the vertical through hole of above-below direction, described center shaft is slidably passed is nested with in described vertical through hole, and described simultaneously hinged with an end of described the first side strut bar and the second side strut bar to the center shaft lower end, the other end of described the 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 mechanical 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 is so that manipulator can pulsation-free work.
Described lower end to center shaft is provided with a cross bar, and integral body is inverted T-shape, and described cross bar two ends are arranged with the connecting bore hinged with the first side strut bar and the second side strut bar.
The beneficial effects of the utility model are: can make manipulator keep center of gravity constant when hydraulic ram is had an effect, left clamp arm, right clamp arm are synchronized with the movement, thereby make left and right pincers pin identical with the compression dynamics that needs the lifting machinery and equipment, ensure the lifting effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is that the utility model uses view.
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
Such as Fig. 1, shown in Figure 2, the heavy mechanical hand synchronizer gear, comprise centering strut 1, to center shaft 2, symmetrically arranged the 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 mechanical hand, centering strut 1 is the level of state, one end of center shaft 2 is upward through vertical through hole 11 and can slides up and down in this vertical through hole 11, to cross bar of center shaft 2 other ends welding, the cross bar two ends are arranged with the connecting bore hinged with the first side strut bar 3 and the second side strut bar 4, 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 mechanical hand.
Working process: when heavy mechanical hand brings into operation, heavy-duty machinery left and right tong arm on hand drives respectively the lower end of the first side strut bar 3 and the second side strut bar 4 to two lateral movements, the upper end that drives simultaneously the first side strut bar 3 and the second side strut bar 4 moves downward, thereby drive center shaft 2 is moved downward, and since 1 pair of restriction effect to center shaft 2 of centering strut 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 utility model just explain through diagrams, this specification sheets be not be the utility model to be confined to shown in described concrete structure and the Applicable scope, therefore every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
Except the described technical characterictic of specification sheets, all the other technical characterictics are those skilled in the art's known technology.
