Description
Technical field
The utility model relates to high pedestal jib crane, relates in particular to high pedestal jib crane boom system erecting device.
Background technology
Four-link door seat formula hoisting crane belongs to heavy, big machinery product, mainly concentrate on the lifting of port and pier for various goods, large-scale Four-link door seat formula hoisting crane is from hundreds of tons that weigh, and approximately 50 meters of apogee distance ground levels, are made up of twenties different parts.Wherein jib, trunk beam, large pull bar, rotating disk and the large parts of column four surround a quadrilateral structure, and between each parts, use adapter shaft and associate member connect and consolidate appropriately, can mutually move.When jib, trunk beam and large pull bar are assembled, because three parts are not fixed bodies, and in the aloft work higher than 40 meters, assembling inconvenience, packaging efficiency is low, cost is high, have potential safety hazard.
As shown in Figure 1, prior art is in the time of assembling Four-link door seat formula hoisting crane, after rotating disk and columns assemblies 4 install, hanging equalizing bar and lower link bar assembly 5 and column with hoisting crane installs, hanging jib 1 lift-off with hoisting crane is again connected with jib hinged-support adapter shaft and associate member on rotating disk, then equalizing bar is connected with jib 1 use adapter shaft and associate member with the lower link bar in lower link bar assembly 5, again luffing mechanism 6 is connected with jib 1 use adapter shaft and associate member, then hang trunk beam 2, trunk beam 2 is connected with jib 1 by adapter shaft and associate member 3, because point of connection is greater than 40 meters apart from floor level, when assembling, jib need play and not unclamp with a hoisting crane, trunk beam also needs to play with a hoisting crane, now also need, with the 3rd hoisting crane, installation personnel is winched to the enterprising line operate of jib front end table balustrade, installation personnel need be fastened seat belts, operate again, and now, jib 1 is all extremely unstable with trunk beam 2, therefore very difficult when operation.When jib 1 and trunk beam 2 install, the hoisting crane of the trunk beam that plays can not unclamp, and finally hangs large pull bar 7 first ends adapter shaft and associate member and is connected with column, and the second end is connected with trunk beam 2 with adapter shaft and associate member.In the time that large pull bar 7 is connected with trunk beam 2, due to unfixing between trunk beam 2 and jib 1, there is relative motion, so same very difficult when now large pull bar 7 is installed with trunk beam 2 use adapter shafts and associate member.
Prior art has the following disadvantages: when trunk beam 2 is installed with jib 1, be in aloft work, each personal hoisting crane and steel rope play, it is indefinite under the impact of wind-force, to rock, and need volume and the weight of the adapter shaft of installing all larger, installation personnel operating difficulties, installation difficulty is very large, thereby has reduced installation effectiveness; There is great potential safety hazard; Required hoisting crane quantity is more and work-hours is longer, adds that the installation personnel quantity of input is more and work-hours is longer, has therefore increased cost of installation.When large pull bar and trunk beam are installed, due to unfixing between jib and trunk beam, there is relative motion, therefore also can have similar shortcoming.
