Abstract
A flexibility following balance-regulation waist rope device for a crane belongs to the crane balance-regulation waist rope device. The device has a waist rope with one end which is connected to the central position of a boom via a pin axle and the other end which is connected to an amplitude pulley unit which is connected to the other end portion of the boom via an amplitude drag-line. The device has smart conception and simple structure, which improves the strained condition of the boom and the amplitude consumedly, and during the process of the amplitude, the waist rope causes the boom remain tension state all the time, and further reduces the fatal weakness of the down-warping of the boom, and overcomes the weakness that the waist rope only plays the tension role instantaneously during process of the boom lifting, thereby the service life of the boom is prolonged.
Description
The utility model relates to a kind of hoisting crane and transfers weighing apparatus waist rope device, and weighing apparatus waist rope device is transferred in the flexible servo-actuated of particularly a kind of crane arm support.
At present, the hoisting crane that people use has a waist rope, and waist rope one end is connected the jib midway location with bearing pin; The other end is connected on the luffing drag-line, and luffing drag-line one end connects the luffing assembly pulley; The other end connects an end of jib.When jib begins to lift by crane, the waist rope is instantaneous in tension between luffing drag-line and jib, reduce the stressing conditions of jib, after the jib lifting, the waist rope begins along with the variation of jib to relax, and becomes loose more more, and this not only can not reduce the stressing conditions of jib, strengthen the downwarp amplitude of jib on the contrary, shortened the service life of jib.
It is stressed little that the purpose of this utility model provides a kind of jib, and weighing apparatus waist rope device is transferred in the flexible servo-actuated of a kind of crane arm support of long service life.
The purpose of this utility model is achieved in that this hoisting crane has a waist rope, and waist rope one end is connected the midway location of jib with bearing pin; The other end connects the luffing assembly pulley, and the luffing assembly pulley connects jib the other end by the luffing drag-line.
The luffing assembly pulley is become with the balance assembly pulley by bottom luffing assembly pulley, top luffing assembly pulley, with the solderless wrapped connection of luffing steel rope, the other end of top luffing assembly pulley connects amplitude draw-bar between equalizer pulley and bottom luffing assembly pulley, bottom luffing assembly pulley and top luffing assembly pulley.
Equalizer pulley has a support, and support one end connects pipe link; The other end is an open slot, pulley is arranged in the open slot and is vertically connected on the support with small clevis pin with head.
Owing to adopted such scheme, midway location at the crane amplitude variation jib connects a waist rope with bearing pin, the other end of waist rope connects the luffing assembly pulley, the luffing assembly pulley is by bottom luffing assembly pulley, top luffing assembly pulley becomes with the balance assembly pulley, at equalizer pulley and bottom luffing assembly pulley, be connected with the luffing steel rope between bottom luffing assembly pulley and the top luffing assembly pulley, the other end of top luffing assembly pulley connects amplitude draw-bar, amplitude draw-bar connects jib one end with the luffing drag-line, equalizer pulley has a support, support one end connects pipe link, and pipe link connects the waist rope.When crane arm support lifted by crane, the luffing steel rope contracted to recovery, and the luffing assembly pulley drives the luffing drag-line on the one hand and jib hoists; Also move on the one hand with equalizer pulley, equalizer pulley and waist rope, connect as one also between waist rope and the jib and change along with the change of luffing assembly pulley, so rope makes jib keep tensioning state all along in the amplitude changing process middle part of the side, reduced the stressing conditions of jib, reduce the downwarp amplitude of jib, having overcome jib waist rope moment when lifting plays the weakness of tension, reached the purpose of this utility model, this structural framing is ingenious, simple in structure, not only improve the strained condition of jib and luffing greatly, but also reduce the deadly defect of jib downwarp, prolonged the service life of jib.
Be further described in conjunction with the embodiments with reference to the accompanying drawings below.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the luffing pulley block structure figure of Fig. 1.
In the drawings, this hoisting crane 7 has a waist rope 3, waist rope 3 one ends connect the midway location of jib 1 with bearing pin 8, the other end connects luffing assembly pulley 4, luffing assembly pulley 4 is by bottom luffing assembly pulley 9, top luffing assembly pulley 11 and equalizer pulley 5 are formed, between equalizer pulley 5 and bottom luffing assembly pulley 9, be connected with luffing steel rope 6 between bottom luffing assembly pulley 9 and the top luffing assembly pulley 11, the other end of top luffing assembly pulley 11 connects amplitude draw-bar 12, amplitude draw-bar 12 usefulness luffing drag-lines 2 connect jib 1 one ends, equalizer pulley 5 has a support 13, support 13 1 ends connect pipe link 10, and pipe link 10 connects waist rope 3; The other end is an open slot, has pulley 15 also to be vertically connected on the support 13 with small clevis pin with head 14 in the open slot.
