Abstract
The utility model discloses a connecting device of a jib and a hook in a crane. The connecting device comprises side support plates arranged symmetrically to each other; the side surface of each side support plate is an integrity formed by an upper trapezoid surface which is narrow in the upper part and wide in the lower part, a rectangular surface, and a lower trapezoid surface which is wide in the upper part and narrow in the lower part; a through hole is formed in the middle each rectangular surface; a core shaft is arranged in each through hole; a fixed pulley is arranged in each core shaft; a connecting hole is formed in the middle of a support shaft; the connecting device comprises a hook; a threaded shaft is arranged in the head part of the hook; the threaded shaft penetrates the connecting hole, and is fixed onto the support shaft through a nut; a stabilizing block corresponding to the upper trapezoid surface in shape is arranged on the surface of the upper trapezoid surface. The connecting device provided by the utility model is simple in structure and convenient to manufacture, and can reduce swing amplitude of the hook, reduce friction among parts, reduce wear of relative parts, prolong the service life, and avoid damage to a human body caused by the swing of the hook.
Description
Technical field
The utility model relates to a kind of automobile-mounted hoisting device, specifically, relates to the connecting device of a kind of crane arm and suspension hook.
Background technology
In prior art, the suspension hook of truck with loading crane is after completing lifting, because the deadweight of suspension hook is low weight, reciprocally swinging under the Action of Gravity Field of self, the friction that has increased parts, accelerated the wearing and tearing of related components, reduce service life, also easily cause personal injury simultaneously.
The utility model content
For above-mentioned deficiency of the prior art, it is a kind of simple in structure, easy to make that the utility model provides, and can reduce the crane arm of suspension hook swing and the connecting device of suspension hook.
Technical solution adopted in the utility model is:
The connecting device of a kind of crane arm and suspension hook, comprise symmetrically arranged side stay bearing plate, side stay bearing plate cross-sectional plane is rectangle, the side of side stay bearing plate is comprised of integrated up-narrow and down-wide upper trapezoid face, rectangular surfaces and lower trapezoid face wide at the top and narrow at the bottom, the rectangular surfaces middle part of described side stay bearing plate is provided with through hole, be provided with mandrel in through hole, mandrel is provided with fixed pulley; The rectangular surfaces of side stay bearing plate is provided with for connecting the tapped bore of left side stay bearing plate and right side stay bearing plate; Bolt links into an integrated entity left side stay bearing plate and right side stay bearing plate; The lower trapezoid Mian center of side stay bearing plate is provided with pivot shaft; The pivot shaft middle part is provided with connecting bore; Comprise suspension hook, the head of suspension hook is provided with threaded shaft, and threaded shaft is fixed on pivot shaft by nut through connecting bore, and the surface of upper trapezoid face is provided with the stable piece corresponding with upper trapezoid face shape.
Described fixed pulley is the 2-4 group.
Described tapped bore is four rectangular surfaces edges that are arranged on the side stay bearing plate; The pitch-row that is arranged on two tapped bore of top is greater than the pitch-row of two tapped bore that are arranged on below.
The beneficial effect of the relative prior art of the utility model:
The connecting device of the utility model crane arm and suspension hook, simple in structure, easy to make, can reduce the suspension hook amplitude of fluctuation, reduce the friction of parts, reduce the wearing and tearing of related components, increase service life, avoid suspension hook to swing and cause personal injury, reduce the lifting time, increase work efficiency.
