Abstract
The invention discloses a welding tool for an inclined ladder of a crane, which comprises a rectangular framework comprising a pair of short plates and a pair of long plates; left and right sealing head plates are respectively fixed on the pair of short plates of the rectangular framework; a positioning backup plate is fixedly arranged on the long plate on one side, and a movable backup plate driven by a pull-pull device to move forwards and backwards along the two sealing head plates is arranged on the long plate on the other side; and pedal fixed seat plates are vertically distributed on the pair of long plates in positions between the positioning backup plate and the movable backup plate at intervals and are inclined for 60 degrees relative to the horizontal plane through triangular supporting plates respectively fixed on the long plates on the two sides. The inclined ladder welding tool has the advantages that the structure is simple, the operation is convenient, the production efficiency of the inclined ladder of the crane is greatly improved, and the labor investment is reduced; and the precision of the inclined ladder and the overall quality of products are improved, no correction is required (the deformation tolerance of the inclined ladder can be controlled within the design tolerance range of 2 mm), and the problem of welding deformation is effectively solved.
Description
Technical field
The present invention relates to crane inclined ladder, especially relate to a kind of crane inclined ladder welding tooling.
Background technology
Every platform bridge (door) formula crane all needs inclined ladder, and namely inclined ladder is the indispensable parts of bridge (door) formula crane, and the manufacturer's standard of inclined ladder is pressed GB3811-2008 and performed.The manufacture method of conventional crane inclined ladder is: first according to parts on design drawing the blanking of size list, then need at least two workmans to carry out ruling on platform, organize right, welded, two workmans can weld three inclined ladders every day under normal circumstances again.Owing to being that line group is right on platform, not by any tooling fixture, inclined ladder distortion after welding is about 8mm, 6mm is exceeded with the standard of design tolerance 2mm, so, also need after having welded to repair, deflection is repaired within the scope of design tolerance, both lost labor's expense, operating efficiency is also low.
Summary of the invention
The object of the present invention is to provide the crane inclined ladder welding tooling that a kind of operating efficiency is high, finished product deflection is little.
For achieving the above object, the present invention can take following technical proposals:
Crane inclined ladder welding tooling of the present invention, it comprises the rectangular frame be made up of a pair short slab and a pair long slab, a pair short slab of described rectangular frame is fixed with left and right head plate respectively, the long slab of side is wherein fixedly installed location backup plate, opposite side long slab is provided with and drives along the movable Active guide fence of two head plates by push-pull device at fixed, described left and right head plate is the U-lag plate structure arranged in opposite directions, and the roller that described Active guide fence two ends are arranged respectively is along the U-lag scroll forward and backward of described head plate; On a pair long slab between location backup plate and Active guide fence, perpendicular separation is evenly equipped with pedal fixed base plate, and described pedal fixed base plate is obliquely installed horizontal by 60 ° by the triangular support plate be separately fixed on the long slab of both sides.
Between two short slabs of described rectangular frame, be provided with adjusting screw(rod), one end of described adjusting screw(rod) is extended outside framework, and its end is provided with adjusting handle; The middle part of the pedal movable base plate be crisscross arranged with described pedal fixed base plate is connected with described adjusting screw(rod) by active rotating shaft, the two ends of pedal movable base plate are connected with the long slab of both sides respectively by passive rotating shaft, and described active rotating shaft and passive shaft parallel are arranged.
Described push-pull device at fixed is the shrinking connecting-rod driven by hydraulic means.
The invention has the advantages that structure is simple, easy to operate, substantially increase the production efficiency of crane inclined ladder, weld three inclined ladders every day by original two workmans and bring up to a workman and can weld five inclined ladders every day, reduce investment in human resources; Improve accuracy and the integral product quality of inclined ladder, without the need to correcting (distortion tolerance of inclined ladder can be controlled within the scope of the design tolerance of 2mm), effectively controlling the problem of welding deformation.
Accompanying drawing explanation

Fig. 2 is the plan structure schematic diagram of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, crane inclined ladder welding tooling of the present invention, it comprises the rectangular frame 1 be made up of a pair short slab and a pair long slab, a pair short slab of rectangular frame is fixed with left head plate 2 and right head plate 3 respectively, the long slab of upside is fixedly installed location backup plate 4, downside long slab is provided with and drives along the movable Active guide fence 5 of two head plates by push-pull device at fixed; On a pair long slab between location backup plate 4 and Active guide fence 5, perpendicular separation is evenly equipped with 20 pedal fixed base plates 6, and pedal fixed base plate 6 is obliquely installed horizontal by 60 ° by 40 the triangular support plates 7 be separately fixed on the long slab of both sides; For ease of operation, push-pull device at fixed can be the shrinking connecting-rod 14 driven by hydraulic means 13, also can by Non-follow control.Because the angle of foot board of most crane inclined ladder is 60 °, so, when using this frock to weld inclined ladder, first the epipleural 17 of ladder is located on backup plate 4 by being placed on, the pedal of ladder is successively placed on horizontal by the pedal fixed base plate 6 of 60 °, then by the lower side panel 18 of ladder by being placed on the top of Active guide fence 5, start push-pull device at fixed (hydraulic-driven or hand drive), promote Active guide fence 5 by the epipleural 17 of inclined ladder, lower side panel 18 and 20 pedal jam-packeds, with welding machine, it is spot-welded together, the side of inclined ladder and pedal can unify blanking, the whole course of work is without the need to laying-down again, hold up without the need to people, the inclined ladder deflection of some postwelding is very little, each geometric data all can meet Design Requirement Drawing, effectively solve welding deformation problem, improve operating efficiency and work quality.
Due in gantry crane design, the angle of foot board of some inclined ladder is less than 60 °, for the inclined ladder of satisfied different angle of foot board makes, between two short slabs of rectangular frame, is provided with adjusting screw(rod) 8, one end of adjusting screw(rod) 8 is extended outside framework, and its end is provided with adjusting handle 9; The middle part of the pedal movable base plate 10 be crisscross arranged with pedal fixed base plate 6 is connected with adjusting screw(rod) 8 by active rotating shaft 11, the two ends of pedal movable base plate 10 are connected with the long slab of both sides respectively by passive rotating shaft 12, and active rotating shaft 11 and passive rotating shaft 12 be arranged in parallel.When needing the inclined ladder of non-60 ° of welding foot pedal, pedal 19 is placed on pedal movable base plate 10, then adjusting screw(rod) 8 is rotated, after adjusting to proper angle, promote Active guide fence 5 again by the epipleural 17 of inclined ladder, lower side panel 18 and 20 pedal 19 jam-packeds, with welding machine, it is spot-welded together.
Frictional force during for reducing mobile between Active guide fence 5 and two head plates, left head plate 2 and right head plate 3 be the U-lag plate structure arranged in opposite directions, at the roller 15 of Active guide fence 5 two ends setting and the roller 16 U-lag scroll forward and backward along head plate.
