Abstract
The invention discloses an electric hoist with four hoisting points and solves the technical problem that the prior crane electric hoist unsteadily hoists a heavy object with a large plane. The structure includes an electric hoist body which is composed of a drum, a motor and a reducer; two rows of rope grooves are formed on the drum; the rotating direction of the two rope grooves from the middle to one end is the left rotating direction, while the rotating direction of the two rope grooves from the middle to the other end is the right rotating direction; each of the rope grooves is fixedly wound with a hoisting cable, wherein the two hoisting cables going upwards is led by a fixed pulley to form the four hoisting points with the two hoisting cables going backwards and downwards; when the drum is rotated, the hoisting cables are respectively wound to the two sides, and the four hoisting points move up and down at the same time. The electric hoist is used for hoisting the heavy objects with large planes.
Description
Technical field
The present invention relates to the hoisting crane electric block.
Background technology
The electric block of hoisting crane all is single rope stretching or two rope stretchings at present, and a suspension centre or two suspension centres are promptly arranged, and is not steady when causing the weight on the big plane of lifting like this, is sought after a kind of electric block of many suspension centres
Summary of the invention
The present invention provides a kind of electric block of four-point lifting for overcoming the deficiencies in the prior art.
For achieving the above object, structure of the present invention is: comprise by reel, motor, the electric block body that retarder is formed, it is characterized in that, be processed with double grooving on the reel, begin grooving rotation direction to an end from the centre and be left-handed to, to the grooving rotation direction of the other end be dextrorotation to, therefore on the reel left-handed twice are arranged, the dextrorotation twice, have four road groovings, the fixing steel cable that twines of per pass grooving, wherein form four suspension centres to two steel ropes of overlap by fixed pulley guiding back and two steel ropes to underlap, steel rope twined to both sides respectively when reel rotated, and four suspension centres are up-and-down movements simultaneously.
Good effect of the present invention is: hang steadily with four suspension centres when lifting by crane the weight on big plane, not the left-right and front-back deflection.
Description of drawings
Fig. 1 is the reel and the rope distributing method front view of the embodiment of the invention.
Fig. 2 is the left view of Fig. 1.
Marginal data: 1-reel; The left-handed double grooving of 2-; 3,4-overlap steel rope; The double grooving of 5-dextrorotation; 6,7-underlap steel rope.
The specific embodiment
As shown in Figure 1 and Figure 2.The present invention includes by reel 1, motor (not drawing among the figure), the electric block body that retarder (not drawing among the figure) is formed, be processed with double grooving on the reel 1, the grooving that wherein begins from the centre to left end is left-handed double grooving 2, grooving to right-hand member is the double grooving 5 of dextrorotation, therefore have four road groovings on the reel 1, the fixing steel cable that twines of per pass grooving, wherein two of overlap steel ropes 3 and 4 are by moving downward after the fixed pulley guiding and underlap steel rope 6 and 7 forms four suspension centres 6, overlap steel rope 3 when reel 1 rotates, underlap steel rope 6 and overlap steel rope 4, underlap steel rope 7 twines to both sides respectively, four suspension centre while up-and-down movements.
Claims (1)
1, a kind of electric block of four-point lifting, it comprises the electric block body of being made up of reel, motor, retarder, it is characterized in that, be processed with double grooving on the reel, begin grooving rotation direction to an end from the centre and be left-handed to, to the grooving rotation direction of the other end be dextrorotation to, left-handed have twice, dextrorotation has twice, the fixing steel cable that twines of per pass grooving, wherein form four suspension centres to two steel ropes of overlap by fixed pulley guiding back and two steel ropes to underlap, steel rope twined to both sides respectively when reel rotated, and four suspension centres are up-and-down movements simultaneously.
