Description
Technical field
The utility model belongs to gantry crane's supporting legs field, and relating to one in particular can Fast Installation and easy-to-dismount gantry crane's supporting legs automatically.
Background technology
Present main beam of gantry crane and supporting leg with bolts, field installation steps is: sling after 1) supporting leg being connected with cross sill, and fix with four cable wind ropes, same method founds two ends supporting leg, general needs one time, and security maintenance is set and sends someone to keep an eye on; 2) tackles is hung on girder, above lifting girder to supporting leg, adjustment leg location, falls girder, beats locating dowel pin, wear tens hinged bolts.Common because making the bad or structural distortion and all bolts cannot being penetrated in transit of precision, installation personnel usually adopts on-the-spot gas cutting reaming, or there is the phenomenon of neglected loading bolt, girder and supporting leg solder together, gantry crane finally can be caused to run bad and there is potential safety hazard.
For some mobile construction enterprises, a collection of electric block gantry crane of normal use, need frequent demolition, installation, existing transfer crane cannot meet the demand of this kind of client's mobile operation.
Utility model content
The technical problems to be solved in the utility model be to provide a kind ofly convenient to install, the transfer crane of the two hinged supporting leg of dismounting.
For solving the problems of the technologies described above, the utility model provides a kind of gantry crane's supporting legs, comprise girder, the uniform cross-arm be arranged on girder, tackles, girder supporting leg is provided with bottom described girder, described girder supporting leg comprises and is arranged at the flexible leg of girder bottom end and the rigid leg of the other end respectively, described rigid leg comprise main limb and with main limb oblique limb at an angle, described flexible leg and main limb are hinged with cross-arm on girder respectively, and on described oblique limb and girder, cross-arm is bolted.
Preferably, described flexible leg is vertical with girder with main limb, is connected bottom described oblique limb with main limb.
Preferably, cart running gear is provided with bottom described flexible leg and rigid leg.
Preferably, described rigid leg is provided with cat ladder.
Gantry crane's supporting legs of the present utility model, before upright installation, flexible leg and girder cross-arm hinged, flexible leg and girder are 2 components, flexible leg has 1 revolute pair to ground, flexible leg and girder have 1 revolute pair, and the degree of freedom of mechanism is according to formula F 1=3N1-2FL1-FH (wherein, F-degree of freedom, n-movable part number, FL-lower pair, FH-higher pair), the degree of freedom calculating mechanism is 2; The main limb of rigid leg and girder cross-arm hinged, main limb has 1 revolute pair to ground, and main limb and girder have 1 revolute pair, and how rigid leg has added 1 oblique limb of component, 2 revolute pairs of oblique limb and ground, girder are brought into, so the degree of freedom of mechanism draws it is 1 according to formulae discovery.
Gantry crane's supporting legs of the present utility model, after upright installation, oblique limb and girder cross-arm bolt, rigid leg and girder become 1 component, and the first number of mechanism reduces to 2, and the revolute pair on flexible leg and rigid leg degree ground still exists, flexible leg exists the revolute pair of girder, so lower pair is 3, the degree of freedom according to this transfer crane mechanism of formulae discovery is 0, and mechanism becomes robust structure.
Transfer crane installation steps of the present utility model:
1) on ground girder and supporting leg hinged good, tackles, casual cable are installed, utilize wheel crane to hang into erectility, be placed on ground rail;
2) installation personnel is on girder on the upright cat ladder of rigid leg, fastens seat belts;
3) squeeze into the locating dowel pin on girder cross-arm and rigid leg connecting panel, then penetrate high strength bolt and fastening;
4) check cross sill wheel and rail contact well, wheel crane is thrown off;
5) install cart to drive, hoisting crane is automatically controlled, and energising test run, namely completes.
Transfer crane demounting procedure of the present utility model:
1) cart driving mechanism is removed;
2) wheel crane hangs up properly girder and tensioning lifting rope;
3) installation personnel is on girder on the upright cat ladder of rigid leg, fastens seat belts;
4) remove high strength bolt on girder cross-arm and rigid leg connecting panel, get locating dowel pin;
5) gantry crane fell on the support on ground by wheel crane swing arm;
6) remove the parts such as cucurbit, entrucking is transported.
The beneficial effect of employing technique scheme is: transfer crane of the present utility model, due to the improvement of supporting leg, make the complicated assembly and adjustment work of transfer crane can whole complete fields on ground, the aloft work of original 2 ~ 3 days is reduced to 2 ~ 3 hours ground installation and debugging and sling install until lifting machine installation, and this operating process is carried out under the state of a safety, this is concerning the operating environment improving installer outdoor especially field strong wind atmosphere greatly, improve work efficiency, improve job safety coefficient, and this gantry crane's supporting legs, install, dismantle all efficient and convenient, structure is simple and firm, the mobile operation of some projects can be met to greatest extent, provide cost savings.
