Abstract
The invention discloses an overweight electric hoist which comprises two winding drums and a pulley block. The two winding drums are mounted reversely and arranged in a staggered manner; a steel wire rope is respectively connected with the two winding drums through the pulley block; the pulley block at least includes four fixed pulleys and five movable pulleys; hanging hooks are mounted on the movable pulleys of the pulley block. The invention has the advantages of convenient use, safety and reliability, and expands the lifting range of the electric hoist.
Description
Technical field:
The present invention relates to hoisting crane, particularly a kind of electric block of energy lifting large-tonnage goods.
Background technology:
Existing electric block plays the restriction that liter weight is subjected to power of electric motor and steel rope load-bearing, and it is limited to play liter weight.A lot of existing electric blocks of large-tonnage goods all can not lifting, has caused a lot of troubles to the user, has influenced production efficiency, has increased productive costs.
Summary of the invention:
The purpose of this invention is to provide overweight electric block a kind of simple in structure, easy to use.Task of the present invention is done in such a way that overweight electric block, and it comprises two reels, and an assembly pulley is characterized in that: two reels are oppositely installed, and dislocation is arranged, and steel rope is connected respectively with two reels by assembly pulley.Assembly pulley is made up of fixed pulley and movable pulley.Assembly pulley is made up of 4 quiet pulleys and 5 movable pulleys at least.On the movable pulley of assembly pulley, suspension hook is installed.The present invention is easy to use, and is safe and reliable, increased the lifting scope of electric block.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Drawing explanation: 1, reel, 2, fixed pulley, 3, movable pulley, 4, suspension hook, 5, steel rope.
The specific embodiment:
Specifically describe embodiment in conjunction with the accompanying drawings, the present invention is by two reels, and an assembly pulley is formed, and two reels 1 are oppositely installed, and dislocation is arranged, and steel rope 5 passes assembly pulley and is connected respectively with two reels.Assembly pulley is made up of fixed pulley 2 and movable pulley 3.Assembly pulley is made up of 4 fixed pulleys and 5 movable pulleys at least.Suspension hook 4 is installed on the movable pulley of assembly pulley.When two reel run-in synchronisms, it drives steel rope separately, drives suspension hook by assembly pulley, realizes the task of hoisting heavy.The present invention is simple in structure, and is easy to use, and can increase the quantity of assembly pulley middle pulley according to different weight of heavy, satisfies the lifting of the weight of Different Weight.
Claims (4)
1, overweight electric block, it comprises two reels, and an assembly pulley is characterized in that: two reels are oppositely installed, and dislocation is arranged, and steel rope is connected respectively with two reels by assembly pulley.
