Description
Technical Field
The utility model relates to a tailor-welding frock technical field, more specifically say, it relates to a tower jib loading boom transition section tailor-welding frock.
Background
At present, splicing welding of a transition section of a tower crane boom is performed by using an upper standard section and a lower standard section of the transition section as reference splicing welding, splicing is needed before welding, four main chords are connected with the standard sections debugged at two sides, and then a middle web member is spliced.
Chinese patent with publication number CN203664947U discloses a tower crane boom transition section tailor-welding tool, which comprises a rotating frame and supporting frames arranged at two end parts of the rotating frame, wherein the rotating frame can rotate on the supporting frames, the rotating frame comprises a main rotating disc and a slave rotating disc, the main rotating disc and the slave rotating disc are connected through a plurality of connecting rods to form a frame structure, four main rotating disc connecting seats are arranged on the main rotating disc, four slave rotating disc connecting seats are arranged on the slave rotating disc, and two ends of four main chord members of the tower crane boom transition section can be respectively fixed on the main rotating disc connecting seats and the slave rotating disc connecting seats.
Above-mentioned technical scheme accessible revolving rack drives the transition section rotatory to make things convenient for the web member to assemble, but at its unable convenient transition section clamping to not unidimensional dress.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a tower jib loading boom transition section tailor-welding frock.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a tower jib loading boom transition section tailor-welding frock, includes two support frames, two rotate on the support frame and be connected with the rotor plate that is the rectangle, four sliding trays have been seted up along its diagonal on the rotor plate surface, the rotor plate surface has the connecting seat through sliding tray sliding connection, the lower fixed surface of connecting seat be connected with sliding connection in sliding block in the sliding tray, the sliding tray internal rotation is connected with the actuating lever, the actuating lever pass and threaded connection in the sliding block, the one end of actuating lever is stretched out the corner and the fixedly connected with rotation handle of rotor plate, the fixed surface of connecting seat is connected with L shape limiting plate.
Through adopting above-mentioned technical scheme, when welding the transition section, adjust the distance between four L shape limiting plates through rotating the handle, the rectangle that makes its formation slightly is greater than the rectangle that four main chord end of transition section formed, place the both ends of transition section between two rotor plates, and continue to adjust the distance between limiting plate and the four main chord of transition section through rotating the handle, and finally make the inner wall of L shape limiting plate press from both sides tightly in the lateral wall of main chord, in order to fix a position the transition section, and rotate through driving the rotor plate, in order to adjust the angle of transition section, and through the position of adjusting the connecting seat, in order to fix a position the transition section of different specification sizes.
The utility model discloses further set up to: and scales are arranged on the surface of the rotating plate along the length direction of the sliding groove.
Through adopting above-mentioned technical scheme, before the transition section to different specifications fixes a position, according to its specific size of a dimension, the accessible is adjusted in advance the position of limiting plate to the scale to the convenience is fixed to the transition section.
The utility model discloses further set up to: and the inner side wall of the L limiting plate is fixedly connected with a rubber pad.
Through adopting above-mentioned technical scheme, through setting up the rubber pad, when playing the guard action to main chord member, effectively promoted the stability of transition section when carrying out the tailor-welding work.
