Abstract
The utility model discloses a tower crane jib loading boom pull rod welding frock, including the base, be connected with on the base and connect I, connect II, connect III and V type seat, connect arch in the middle of I top, connect II and to connect III both sides protruding, middle sunken. The utility model discloses simple structure, convenient and practical has optimized the mode of product marking off, location, has saved the weld time of standard festival, has improved production efficiency, and being equipped with each size and connecting, can satisfy the jib loading boom pull rod production of multiple different models, the commonality is strong, structural arrangement is reasonable simultaneously, has higher reliability and stability.
Description
Technical field
This utility model relates to a kind of derrick crane and produces frock, belongs to specifically a kind of jib for tower crane pull bar welding tooling of engineering machinery field.
Background technology
The crane arm pull bar welding of derrick crane at present is general uses manual line, the mode of location to weld, and inefficiency, takes time and effort and size easily produces error；If the mode taking frock bearing pin to position is fixed, though being easy to the upper and lower part of product, but integral solder can not carry out turning operation, causes crane arm pull bar part welding bead to weld.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of jib for tower crane pull bar welding tooling, crane arm pull bar capable of being compatible with multi-type, and location is convenient, greatly improves production efficiency and reduces labor intensity.
To achieve these goals, the technical solution adopted in the utility model is: a kind of jib for tower crane pull bar welding tooling, including base, base connects and has joint I, joint II, joint III and V-type seat；Described joint I crown center is protruding, and described joint II and joint III both sides are protruding, medial recess.
Further, the projection of described joint II and joint III both sides has through hole, joint II is provided with frock bearing pin in order to steady brace by through hole, joint III is provided with suspension ring bearing pin by through hole, in order to the otic placode on steady brace and pull bar.
Further, described suspension ring bearing pin is provided with spacer, in order to ensure the spacing of otic placode.
Further, described joint I, joint II, joint III and V-type seat are fixed on base by bolt and taper pin with internal thread, fixed, and convenient dismounting.
Further, described base is also associated with connecting plate, has taken into account the pull bar of each size greatly, has improve versatility.
The beneficial effects of the utility model are: optimize product line, the mode of location, save the weld interval of standard knot, improve production efficiency；And it being equipped with each size joint, the crane arm pull bar that can meet multiple different model produces, highly versatile；Reasonable structural arrangement simultaneously, has higher reliability and stability.
Accompanying drawing explanation
Fig. 1 is this utility model structural front view；
Fig. 2 is this utility model top view.
In figure: 1, base, 2, joint I, 3, V-type seat, 4, joint II, 5, joint III, 6, connecting plate.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of jib for tower crane pull bar welding tooling, including base 1, base 1 connects and has joint I 2, joint II 4, joint III 5 and V-type seat 3；Described joint I 2 crown center is protruding, and described joint II 4 and joint III 5 both sides are protruding, medial recess.
Further, the projection of described joint II 4 and joint III 5 both sides has through hole, joint II 4 is provided with frock bearing pin in order to steady brace by through hole, joint III 5 is provided with suspension ring bearing pin by through hole, in order to the otic placode on steady brace and pull bar.
Further, described suspension ring bearing pin is provided with spacer, in order to ensure the spacing of otic placode.
Further, described joint I 2, joint II 4, joint III 5 and V-type seat 3 are fixed on base 1 by bolt and taper pin with internal thread, fixed, and convenient dismounting.
Further, described base 1 is also associated with connecting plate 6, has taken into account the pull bar of each size greatly, has improve versatility.
Each for crane arm pull bar part is fixed on joint I 2, V-type seat 3, joint II 4 and joint III 5, joint I 2 intermediate projections embeds pull bar, joint II 4 and joint III 5 are respectively by frock bearing pin and suspension ring bearing pin steady brace, and suspension ring bearing pin fixes otic placode to ensure spacing by the spacer that is mounted above, after checking each crucial size for connection to meet design requirement subsequently, carry out product overall spelling means of spot welds and welding, to be welded complete after suspension ring bearing pin and bearing pin are extracted, unload lower link.
In sum, this utility model simple in construction, convenient and practical, optimize product line, the mode of location, save the weld interval of standard knot, improve production efficiency；And it being equipped with each size joint, the crane arm pull bar that can meet multiple different model produces, highly versatile；Reasonable structural arrangement simultaneously, has higher reliability and stability.
