Abstract
The utility model relates to the field of crane lifting appliances and especially relates to a balance lifting appliance of an ultra-high head crane. The balance lifting appliance comprises a lower balance beam; two parallel lateral balance beams are symmetrically arranged above two ends of the lower balance beam; and the lower balance beam and two lateral balance beams are I-shaped and vertically arranged. Fixed lifting points are respectively arranged on two ends of the lateral balance beams; lateral lifting shafts are arranged on middle parts of the lateral balance beams; lower lifting shafts are arranged on two ends of the lower balance beam; lateral lifting posts are arranged among the lateral balance beams and the lower balance beam, extend along the vertical direction and have two ends respectively hinged with the lateral lifting shafts and the lower lifting shafts vertically; and a lifting hook is suspended on the middle part of the lower balance beam. The balance lifting appliance can guarantee the synchronization of four lifting points and solves the problem of asynchronous lifting points caused by the twisting, knotting and automatic loosening of the steel rope in the process of falling in the prior art.
Description
Technical field
The utility model relates to the crane hanger field, particularly a kind of ultrahigh pump lift crane balance suspender.
Background technology
Along with metallurgical and other all kinds of heavy-duty machineries constantly to the improvement of large scale development and traditional handicraft, the requirement of ultrahigh pump lift hoisting crane is increasing.But the suspender of ultrahigh pump lift hoisting crane adopts lifting hook pulley group canoe usually at present, and the length of steel wire is longer, and the length of steel wire is at least the twice lift.Suspender only has an equalizing bar, the two ends of equalizing bar respectively are provided with a movable pulley, when ultrahigh pump lift hoisting crane during in the decline process, with respect to high-lift, distance between the steel rope of movable pulley both sides almost can be ignored, and two sections steel ropes can be similar to regard coincidence as point-blank, the knotting so the steel rope of movable pulley both sides is easy to twist, steel rope passes through to be ground pine easily behind the pulley, and then loose voluntarily.Therefore there is following shortcoming in existing ultrahigh pump lift hoisting crane: the reel dimensional structure is large, the rope drift angle is large under the steel rope, steel rope reverses knotting, loose voluntarily because sth. made by twisting steel rope occurs around power release in ultrahigh pump lift, four suspension centres asynchrony phenomenon occurs in the decline process.Therefore, existing ultrahigh pump lift hoisting crane affects the normal use of lifting mechanism to a certain extent, can't satisfy the requirement of ultrahigh pump lift (H=370m) weight-lifting equipment.
Summary of the invention
The purpose of this utility model provides a kind of ultrahigh pump lift crane balance suspender, reverses knotting, the nonsynchronous problem of the loose suspension centre that causes voluntarily to solve prior art steel cable in the decline process.
In order to address the above problem, the utility model adopts following technical scheme: ultrahigh pump lift crane balance suspender, comprise lower equalizing bar, the top at the two ends of described lower equalizing bar is arranged with two parallel lateral balance beams, lower equalizing bar is with two lateral balance beams that I shape is vertical to be arranged, the two ends of described each lateral balance beam respectively are provided with a fixing suspension centre, the middle part of each lateral balance beam is provided with the side hanging axis, the two ends of lower equalizing bar are provided with lower hanging axis, be provided with between each lateral balance beam and the lower equalizing bar along the vertical direction the two ends of extending respectively with the vertical hinged side davit with lower hanging axis of side hanging axis, the middle part of lower equalizing bar is hung with a suspension hook.
Described suspension centre is provided with anti-rotation device, described anti-rotation device comprises rotating prevention sleeve, rig thimbler from the bottom up successively, the bow shackle that one end of described rotating prevention sleeve uses by two pairings is connected with the end of lateral balance beam, and the other end of described rotating prevention sleeve is connected with rig thimbler by a bow shackle.
The utility model ultrahigh pump lift crane balance suspender, adopt the vertically disposed lower equalizing bar of I shape and three equalizing bar combinations of two lateral balance beams mode, the array mode that has replaced equalizing bar and two fixed pulleys in the prior art, the two ends of lateral balance beam are respectively equipped with a fixedly suspension centre, this structure is pulled open the stress point of steel rope, distant between four steel ropes, be not easy to occur steel cable and reverse knotting, loose voluntarily, the deadweight of the lateral balance beam steel rope that also can stretch, guaranteed that four suspension centres are synchronous, solved in the prior art that steel cable reverses knotting in the decline process, the nonsynchronous problem of the loose suspension centre that causes voluntarily.
Further, described suspension centre is provided with anti-rotation device, described anti-rotation device comprises rotating prevention sleeve, rig thimbler, the bow shackle that one end of rotating prevention sleeve uses by two pairings is connected with the end of lateral balance beam, the other end of rotating prevention sleeve is connected with rig thimbler by a bow shackle, rotating prevention sleeve can discharge that steel rope in use produces reverses and plays certain counterweight effect, two arc shackle pairings use the junction to form a kind of easy universal hinge body, this universal hinge body is used for transmitting power and the motion between two concurrent aceses, and in transmission process, angle between the diaxon can also change, therefore, can better solve steel rope and in ultrahigh pump lift, steel rope occurs and reverse knotting because twisting with the fingers to discharge around power by installing rotating prevention sleeve and bow shackle between rig thimbler and the lateral balance beam additional, loose problem voluntarily, the suspender own wt steel rope that can stretch simultaneously, to prevent that steel wire torsion knotting from causing asynchronous for actv. more, better guaranteed the safety of lifting.
