Abstract

The utility mode discloses a hoisting mechanism of a portal crane and aims at designing a hoisting mechanism capable of satisfying the heavy weight hoisting requirement of the portal crane. The technical scheme includes that the hoisting mechanism of the portal crane comprises fixed pulley groups, a winding drum and the like, the fixed pulley groups are divided into two groups and parallelly arranged, and shafts of the fixed pulley groups are perpendicular to a shaft of the winding drum. The hoisting mechanism of the portal crane is reasonable in structure, capable of satisfying the heavy weight hoisting and the high hoisting height requirements of the portal crane, compact in overall arrangement and attractive in appearance.

Description

A kind of lifting mechanism of transfer crane
Technical field:
The utility model relates to transfer crane, particularly is applicable to the lifting mechanism of transfer crane.
Background technology:
Present transfer crane, its lifting mechanism often need adopt assembly pulley to assist and hoist, and reel was generally shorter when lifting mechanism was winch; And multiple wraps, if play liter weight when higher, a plurality of fixed pulleys and movable pulley need be set than big elevating height; Fixed pulley is arranged side by side, but if fixed pulley quantity more for a long time, can cause the length of fixed pulley longer; The steel rope angle that is wrapped on the fixed pulley is very big, and steel rope can't be used, and can not satisfy the requirement that hoists of transfer crane.
Summary of the invention:
The purpose of the utility model is the hoist lifting mechanism of the transfer crane that requires of a kind of big weight that can satisfy transfer crane of design.
The technical scheme of the utility model is, a kind of lifting mechanism of transfer crane, and it comprises fixed pulley group, reel etc., and it is characterized in that: the fixed pulley component is two groups of arrangement in parallels, and fixed pulley group axle is vertical with drum shaft.
The utility model is rational in infrastructure, can satisfy the big weight big elevating height requirement of transfer crane, and compact in design, and is comparatively attractive in appearance.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with accompanying drawing, a kind of lifting mechanism of transfer crane, it comprises fixed pulley group 2, reel 1 etc., and the fixed pulley component is two groups of arrangement in parallels, and fixed pulley group axle is vertical with drum shaft.The utility model is two groups with the fixed pulley component; And arrangement in parallel, it is more convenient that the steel rope on the reel twines, and the steel rope angle is excessive in use can not cause transfer crane; The utility model is rational in infrastructure; Can satisfy the big weight big elevating height requirement of transfer crane, and compact in design, comparatively attractive in appearance.
