Abstract
An apparatus for equalizing between asynchronous lifting points of lifter is composed of steel cable, spool for winding said steel cable by multiple layers, spool flanges, equalizing beam, and a spool regulating flange at the internal side of spool flange for changing the active length of spool to equalize between asynchronous lifting points.
Description
Technical field:
The present invention relates to a kind of equipment for balancing outofstep sustained center of crane, the hoisting crane that is specially adapted to have multilaminate coiled reel balance suspension centre asynchronous during with the same weight of the common lifting of a plurality of suspension centres.
Background technology:
When crane hoisting mechanism is usually used the same weight of the common lifting of a plurality of suspension centres, what size can be not absolute because the diameter of each steel rope, each steel rope modulus of elasticity, the stressed size of each steel rope, each steel rope abrasion size, each drum diameter, each drum diameter wear and tear is the same, just make that the rising or falling speed of steel rope and weight point of connection can be not just the same, it is asynchronous to form many suspension centres, and many suspension centres are asynchronous generally to be increased along with the increase of lifting altitude.Many suspension centres are asynchronous to tend to cause that each suspension centre stressedly changes, steel rope twines mutually, makes the lifting mechanism cisco unity malfunction, even causes the accident.This problem is especially outstanding on the lifting mechanism of super large lifting altitude.
Summary of the invention:
Task of the present invention is that the many suspension centres of a kind of solution of proposition are asynchronous, a kind of equipment for balancing outofstep sustained center of crane of energy normal operation on the lifting mechanism of super large lifting altitude, task of the present invention is finished like this: equipment for balancing outofstep sustained center of crane, it comprises the multilaminate coiled reel of steel rope, the reel flange, steel rope and equalizing bar is characterized in that: be fixed with reel in the slow reel flange inboard of rising or falling speed and regulate flange.Regulate the length that flange changes reel by reel, the thickness that its reel is regulated flange is two suspension centres of balance asynchronous just in time.What reel was regulated flange is shaped as semicircle or other geometric configuration.The flange material available metal regulated by reel or non-metallic material is made.The present invention has following effect: after the inboard dead block of the slow reel flange of rising or falling speed is regulated flange, the length of multilaminate coiled reel is shortened, the rising or falling speed of suspension centre is accelerated, and has solved steel rope and has twined mutually, the nonsynchronous problem of suspension centre.
Description of drawings:
Fig. 1 is equipped with the multilaminate coiled reel structure scheme drawing that reel is regulated flange,
Fig. 2 regulates the nonsynchronous structural representation of flange balance crane suspension centre for reel,
Fig. 3 regulates the shape and structure scheme drawing of flange for reel.
The drawing explanation:
1, multilaminate coiled reel; 2, reel is regulated flange; 3, reel flange; 4, steel rope; 5, equalizing bar.
The specific embodiment:
Nonsynchronous phenomenon when working in order to solve the many suspension centres of hoisting crane, at first to make multilaminate coiled reel 1 rotating speed of many suspension centres identical with mechanical means or electric-control method, reel flange 3 on the slow suspension centre of rising or falling speed is inboard regulates flanges 2 with the Bolt Connection reels, the length of this reel 1 has just shortened, the shape that reel is regulated flange 2 can be semicircle or other geometric configuration, reel is regulated the connection of flange 2 can use bolted connection, also can use other bind mode, the thickness that reel is regulated flange 2 is two suspension centres of balance asynchronous just in time, and reel is regulated flange 2 and can be made of metallic material and also can use other material.Because the rotating speed of reel 1 is identical, the coiling number of turns equates, the reel of being made up of two semi-discs on Bolt Connection in reel flange 3 inboards on the slow suspension centre of rising or falling speed is regulated flange 2, the length of this reel has just shortened, when being equipped with reel, regulates when reeling on the multilaminate coiled reel 1 of flange 2 steel rope 4, the total length of the steel rope 4 of reeling is just long than the total length of the steel rope 4 that reel adjusting flange 2 coilings are not installed, the rising or falling speed of the slow suspension centre of rising or falling speed is accelerated, reached the nonsynchronous effect of balance.
