Description

Parallel connection assembly pulley lifting hook
Technical field
The invention belongs to weight-lifting equipment attachment technique field, be specifically related to a kind of lifting hook.
Background technology
Weight-lifting equipment is when lifting cargo; Safety is first major issue that be critical, and relevant national standard has many regulations to this, comprising many regulations of relevant lifting hook; Like hook mechanical property and the hoisting capacity of confirming according to mechanism's working level; Hang reliable and stable safety in order to guarantee to hook, prior art has many technical measures, but still has such or such defective.
For the lifting hook that is used for different load-carryings, should select the assembly pulley of corresponding rated value, but the arrangement of assembly pulley is different, its tractive force to hook distributes also different, and this directly has influence on the stationarity of lifting.
The frame mode of hook is different, also can have influence on the stationarity of lifting.
For example Chinese patent ZL 200920207832.5; Name is called the utility model patent of " ward off rope support of lifting hook and lifting hook "; Disclose a kind of lifting hook, this lifting hook comprises two opposing sideplates, assembly pulley, crossbeam, suspension hook, first ward off rope support, second ward off rope support and the 3rd ward off rope support that structure is identical.Assembly pulley is connected between the biside plate through sheave shaft.Crossbeam is arranged between the biside plate.Suspension hook passes crossbeam and is connected with nut, and said nut cooperates with bearing on the crossbeam.Three ward off rope support are arranged between the biside plate around assembly pulley; First ward off rope support is arranged between assembly pulley and the suspension hook; Second ward off rope support and the 3rd ward off rope support are positioned at the relative both sides of assembly pulley; Each ward off rope support comprises base plate and rope blocking plate, and rope blocking plate is arranged on the base plate at interval, and the distance between the two adjacent rope blocking plates is greater than the diameter of cable wire end.This hoisting hook device is a stationary structure, comprises assembly pulley, presses the in-line formula and connects.The tractive force of its steel rope all is in a straight line, and the suspension plate of the assembly pulley of this structure is also being followed straight line setting to the tractive force of hook, and this layout is unfavorable for preventing that hook from rocking poor stability toward both sides, the left and right sides.
And for example one Chinese patent application numbers 201110037513.6, and name is called the application for a patent for invention of " a kind of lifting hook that can rotate flexibly ", discloses a kind of lifting hook that can rotate flexibly; It comprises suspension hook, crossbeam, thrust baring and nut; The said suspension hook neck of hook passes said crossbeam, and with nut through being threaded, said nut is fixed on said crossbeam top; Said thrust baring is arranged between said crossbeam and the nut, and wherein, the bottom of said crossbeam inner hole wall is provided with one and goes up groove and a lower groove; Said going up in the groove is provided with tourelle, is provided with leakproofing material in the said lower groove; The upper surface of said crossbeam is provided with boss, and the lower surface of said nut is provided with groove, and said boss agrees with groove mutually.This lifting hook hangs over the neck of hook on the plain thrust bearing, assists in the lower end again a radial ball bearing is set, and its objective is the load of bearing vertical direction with plain thrust bearing; Keep out neck of hook lateral drift with radial ball bearing again, still, in order to stop neck of hook deflection; Its application force will conduct to assembly pulley by crossbeam; Cause the lifting hook single-piece not steady, although always the deflection of the neck of hook is general very little, but because its side action moment of leverage is very large.
Summary of the invention
The technical issues that need to address of the present invention are; The lifting hook tractive force that overcomes prior art is following the straight line setting and is being unfavorable for preventing that hook from rocking toward both sides, the using planar thrust baring influences the stable defective of lifting hook single-piece; Provide the parallel connection of a kind of many group assembly pulleys be provided with to the tractive force of lifting hook for three-dimensional be provided with to be beneficial to prevent that hook from rocking, selecting for use the parallelly connected assembly pulley lifting hook of bearing that can the automatic aligning good stability toward both sides, and many group parallel connections are respectively organized load when being provided with and are lowered the requirement of its intensity and also reduce.
The objective of the invention is to be achieved: a kind of parallelly connected assembly pulley lifting hook through following technical proposals; Comprise some groups of assembly pulleys and lift heavy mechanism; Assembly pulley parallel connection at least is provided with two groups, and the sheave shaft that said parallel connection setting is meant the adjacent pulleys group is by the rule setting that is parallel to each other; Every group of assembly pulley comprises symmetrically arranged left suspension plate and right suspension plate, and the position, upper end between left suspension plate and right suspension plate is provided with suspension bracket, and the middle part is provided with sheave shaft, and lower end part connects lift heavy mechanism; Several pulleys are connected on the sheave shaft through bearing, and left suspension plate, right suspension plate and pulley are through being the six roots of sensation two-thread screw that is uniformly distributed with on the circumferential edge at center with the sheave shaft and fastening; Lift heavy mechanism is made up of lift heavy hook support and lift heavy hook; The lift heavy hook support comprises two blocks of lift heavy plates of symmetry, and the position, upper end of lift heavy plate is provided with several hanging axis holes side by side, and the middle part, lower end of lift heavy plate is provided with a crossbeam hole; The left suspension plate of assembly pulley and right suspension plate are connected through the hanging axis hole of two blocks of lift heavy plates of hanging axis and symmetry; Set crossbeam in the crossbeam hole of two blocks of lift heavy plates of symmetry, gooseneck bracket is established in the stage casing of crossbeam, and penetrating boom hole is up and down established in the middle part of gooseneck bracket; The lift heavy hook comprises that suspension rod and symmetry and disjunctor are located at two hooks of suspension rod bottom, and suspension rod is connected through self-aligning thrust roller bearing and the boom hole that is located at the boom hole upper end, and the somewhat larger in diameter of boom hole is in the diameter of suspension rod, and the oral area of hook is provided with self-locking mechanism.
The left suspension plate of assembly pulley and right suspension plate are connected through the hanging axis hole of two blocks of lift heavy plates of hanging axis and symmetry, and the axle of adjacent pulleys group sets by parallel relation.
Parallel connection is provided with at least two group assembly pulleys, and for example two groups, the steel rope of assembly pulley is distributed along rectangular two opposite side settings, it is stable that the three-dimensional distribution of this tractive force extremely helps trailed lifting hook.This measure can be likened explanation as follows, has two kinds of methods to hang now and rises article, and first kind is that with a block length square plate four jiaos hang with rope; An object is hung by central authorities below dull and stereotyped then, and another kind is that the pole two ends hang with rope with a pole; An object is hung by central authorities below pole then; Relatively two kinds of methods can be known, the former is very steady, is not easy to rock than the latter.
It is to be convenient to set suspension rod that generous gooseneck bracket one is set, the 2nd, and the bending strength in deep beam stage casing.
