Description
Technical field
The utility model relates to a kind of Weighting system for single movable-arm floor mast, specifically relates to a kind of circulating water Weighting system for single movable-arm floor mast.
Background technology
Pole is special hoisting equipment important in the construction of work transmission line group tower.Along with the raising of transmission line of electricity voltage class, the tower material weight of electric power pylon and tower height constantly increase, and group tower difficulty of construction increases thereupon, and the weight-lifting equipment difficulty of construction of employing routine is large, inefficiency.Therefore, the design and optimization of large floor pole is the important research content of detail desige.
Single movable-arm floor mast SXD50 is on building tower crane basis, for the Liquified gas tanker of UHV transmission line tower erection construction, use for reference the advantage of two flat arm (two rocking arm) floor mast, the lifting characteristics and advantages design research and development giving full play to tower crane form.Single movable-arm floor mast stands on steel tower center, carries out soft attachment with steel tower, realizes tower material in place by single arm pitching and revolution.Its critical altitude 150m, maximum functional amplitude 20m, most advanced and sophisticated lift heavy 2.5t, biggest lifting capacity 4t.After steel tower construction completes, can realize pole and be contracted in from steel tower top window automatic dismantling in the square scope of 3.4m, be a kind of specialized equipment being highly suitable for tower erection.
Single movable-arm floor mast have employed fixed type counterweight, and counterweight is arranged on equilibrium arm tail end.After counterweight is determined, no matter how the work range of floor mast and hoisting weight change, and the hypsokinesis moment of flexure of counterweight to pole body remains certain value.Therefore maximum when shaft must can bear fully loaded amplitude peak lean forward moment and unloaded minimum radius time maximum centrifugal castor.Obviously, the design of shaft is sub-economic in such cases, causes shaft sectional dimension comparatively large, adds complete machine weight.For the extra-high voltage project of constructing under the rough topographys such as high and steep mountains of being everlasting, namely the increase of complete machine weight means the increase of material transportation, handling labor amount.Therefore the lightness of pole, intelligentized design have very real significance.
For arm tower crane and pole, can significantly improve tower body force-bearing situation, reduction tower body sectional dimension and weight method adopt mobile counterweight technology exactly, when namely arm work produces and leans forward moment, counterweight moves and produces equal hypsokinesis moment of flexure, makes moment of flexure suffered by tower body minimum.
At present, the mobile counterweight method that movable arm tower crane is taked has following 4 kinds:
1, slider-crank mechanism is adopted to realize counterweight Automatic adjusument;
2, utilize 4 connecting rod mechanisms, make the counterweight swing of suspension;
3, to drawing the method for reciprocation cycle, counterweight is moved by steel rope;
4, counterweight moves along equilibrium arm under the traction of independent traction system, adjusts the position of counterweight at any time.
But above-mentioned four kinds of schemes have following deficiency: it is only synchronous with the luffing of arm that the counterweight of design moves, when namely increasing lift heavy when arm work range is constant, the centrifugal castor that the moment that leans forward produced can not be produced by counterweight balance.Therefore tower body still needs to bear larger moment of flexure, can not reach the object reducing tower body sectional dimension.
In addition, due to the existence of the supplementary structure such as connecting rod mechanism or linkage, arm and equilibrium arm can not meet tower machine and draw in holding pole head after constructing and the requirement of removing from steel tower center.
Therefore, for pole operating feature in the construction of transmission line of electricity group tower, design a kind of more succinct moveable counter weight scheme be suitable for, make it can not only reach the load-carrying ability of expection, and can significantly reduce complete machine weight again, be the problem needing research in extra-high voltage project construction badly.
