Description
Technical field
The utility model belongs to crane parts welding tooling field, is specifically related to a kind of welding tooling for jib for tower crane.
Background technology
Derrick crane is called for short tower machine, also known as tower crane, originates from West Europe.Crane arm is contained in towering tower body top, and working space is large, is mainly used in the installation of vertical and horizontal feed and the building element of material in housing construction.Derrick crane is made up of metal structure, operating mechanism and electrical system three part.Metal structure comprises tower body, crane arm and base etc.Operating mechanism hoists, luffing, revolution and walking four part.Electrical system comprises motor, controller, power distribution cabinet, connection line, signal and lighting device etc.
Crane arm is the vitals of derrick crane, during work, amplitude variation trolley will be walked at crane arm lower boom upper surface, so require that the upper and lower chord member of derrick runway girder is straight, particularly lower boom will dock smooth after mounting, not so amplitude variation trolley walking on crane arm can be shaken, running quality is not high, serious wear, impact use.
Crane arm is normally saved by multiple arm and is formed by pinned connection, as shown in Figure 1, each arm joint comprises: a top boom 2, two lower booms 3, many support bars 4, three " U " shape joints 1 and three " shape " joints 5, but " U " shape joint that " U " shape joint of the first arm joint saves than other arms is large, because " U " shape joint of the first arm joint is used for connecting with reversing frame, " U " shape joint on other arms joint has been the effect connecting reciprocal arm joint.Traditional crane arm welding manner has two kinds: one is integral solder mode: the arm joint one_to_one corresponding of welding tooling and crane arm, the length of welding tooling is equal with the length of whole crane arm, the material that this welding tooling consumes is more, and floor space is comparatively large during welding, hoisting transportation difficulty is larger, another kind is Combination Welding mode: by the welding on same welding tooling of much the same for basic size arm joint, eccentric pin shaft is adopted to locate, there is many difficult problems in this welding manner, such as: eccentric pin shaft difficulty of processing is larger, because the usual permissible accuracy of weldment is lower, each joint arm joint is when welding, the flexibility of this arm joint is not obvious, but multiple arm joint is when linking together, reflect the flexibility of crane arm more intuitively, this kind of Combination Welding frock is adopted easily to cause crane arm Integral bending curvature larger, repeatedly need correct and do over again, reduce production efficiency.
As can be seen here, be badly in need of one and both met that cost of manufacture is low, floor space is little, and ensure the frock that crane arm Integral bending curvature is little, become tower machine welding field problem demanding prompt solution.
Utility model content
The technical problems to be solved in the utility model is that to there is floor space for the welding tooling of current crane arm large, the defect that the crane arm Integral bending curvature of welding is large.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
For the welding tooling of jib for tower crane, comprise base, also comprise first to wind up pole socket, second winds up pole socket, first lower edge pole socket and the second lower edge pole socket, first wind up pole socket and the first lower boom seat is positioned at one end of base, second wind up pole socket and the second lower boom seat is positioned at the other end of base, described base is also provided with top boom positioning seat and lower boom positioning seat, top boom positioning seat winds up between pole socket at first pole socket and second that winds up, lower boom positioning seat is between the first lower edge pole socket and the second lower edge pole socket, described base is also provided with multiple tip-lever support, described tip-lever support is between the first lower edge pole socket and the second lower edge pole socket, base is also provided with the mobile support saddle removably connected with it, described mobile support saddle is positioned at one end of base.
Adopt the welding tooling due to jib for tower crane of technical solutions of the utility model, first pole socket that winds up plays " U " shape joint of fixing top boom, second pole socket that winds up plays " one " shape joint of fixing top boom, first lower edge pole socket plays " U " shape joint of fixing lower boom, and the second lower edge pole socket plays " one " shape joint of fixing lower boom.When top boom to be welded and lower boom lie in a horizontal plane on this welding tooling, top boom positioning seat plays a part to support and fixing top boom, lower boom positioning seat plays a part fixing and supports lower boom, tip-lever support plays Horizontal limiting effect to lower boom, lower boom is avoided to move in the horizontal plane, mobile support saddle plays a part to grip to " U " shape joint on the first arm joint of crane arm, mobile support saddle and base removably connect, when welding first arm joint on " U " shape joint time, mobile support saddle is arranged on base, when welding other arms joint, mobile support saddle is taken down, improve the adaptability of frock.
Operation principle:
When other arms of welding crane arm save (non-first arm joint), mobile support saddle is taken down from base, " U " shape joint to be welded on top boom is fixed on first to wind up on pole socket, " one " shape joint to be welded on top boom is fixed on second to wind up on pole socket, is fixed on by top boom on top boom positioning seat." U " shape joint to be welded on lower boom is fixed on the first lower edge pole socket, " one " shape joint to be welded on lower boom is fixed on the second lower edge pole socket, lower boom is fixed on lower boom positioning seat.Tip-lever support carries out multiple spot auxiliary positioning to lower boom, then welds.
When welding the first arm joint of crane arm, first mobile support saddle is taken down from base, top boom is fixed on top boom positioning seat, lower boom is fixed on lower boom positioning seat, tip-lever support carries out multiple spot auxiliary positioning to lower boom, then weld, after the support bar between top boom with lower boom and the support bar between two lower booms weld and terminate, first arm joint is sling, mobile support saddle is arranged on base, " U " shape joint to be welded on the lower boom of the first arm joint is fixed on mobile support saddle, then at the first arm joint below advance expenditure bracer, lower boom and " U " shape joint are aligned, then weld.
