The specific embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
To shown in Figure 10, according to embodiments of the invention, the undersetting assembly comprises undersetting 10 like Fig. 3, and at least two opposite flanks of undersetting 10 are provided with the side attaching parts, and the side attaching parts is provided with pin shaft hole.Undersetting 11 also includes the supporting leg 11 that stretches out from the below, and the standard knot that supporting leg 11 has with tower crane carries out the bonded assembly structure.The undersetting assembly also includes at least two crossbeam transition assemblies 20, is provided with upper ear plate 24 at crossbeam transition assembly 20 upper surfaces, with the corresponding setting of pin shaft hole on the attaching parts of side, and links together through bearing pin and undersetting 10.Lower surface at crossbeam transition assembly is provided with the frame connector 21 that climbs, and the frame connector 21 that climbs is connected through bearing pin with the frame that climbs.Also can carry out detouchable through bolt or other connection structure between crossbeam transition assembly and the side attaching parts is connected.The side attaching parts can also can be fixedly installed on the undersetting 10, such as being welded on the undersetting 10 for being removably disposed on the undersetting 10.
According to embodiments of the invention; In terms of existing technologies, removed supporting leg stock heavy and that be not easy to process, and replaced the function of supporting leg stock through small and exquisite side attaching parts that is easy to process of structure and detouchable crossbeam transition assembly; Make that not only leg assembly is easier to processing down; Reduce manufacturing procedure, reduced tooling cost, and be convenient to guarantee the finish size and the precision of each parts of undersetting assembly.Because crossbeam transition assembly is detachable, therefore, improved the convenience of time leg assembly when transportation greatly, reduced the transportation volume of time leg assembly, reduced traffic cost.
In the present embodiment; The side attaching parts is four groups of transition otic placodes 12 that are arranged on two opposite flanks of undersetting 10; Per two groups of transition otic placodes 12 are set in parallel in same planar side; Make transition otic placode 12 more simple and convenient, and be more convenient for crossbeam transition assembly 20 is provided with and installs with captiveing joint of undersetting 10.Preferably, transition otic placode 12 is perpendicular to its mounting plane.Below per two groups of transition otic placodes 12, removably be provided with 20, two crossbeam transition of crossbeam transition assembly assembly 20 and be arranged in parallel, and lay respectively at the outside of two opposite planar of undersetting 10.More preferably, transition otic placode 12 is along the axial direction setting of undersetting 10.
Transition otic placode 12 is convenient to after transition otic placode 12 is provided with, carry out following process on the one hand perpendicular to mounting plane and along the axial direction setting of undersetting 10, guarantees finish size, position and the precision of pin shaft hole; On the other hand, make that the force structure of transition otic placode 12 is more reasonable, can bear bigger vertical direction application force, increased the support performance of undersetting assembly.
Every group of transition otic placode 12 includes two veneers that laterally arrange; Each veneer along continuous straight runs is set side by side with two pin shaft holes 13; Two pin shaft holes, 13 correspondence settings on two veneers are used for cooperating with the upper ear plate 24 of crossbeam transition assembly 20, thereby crossbeam transition assembly 20 is installed.Two pin shaft holes 13 are used, and make through the crossbeam transition assembly after the bearing pin connection 20 to be difficult for swinging, and connection structure is stable, and support strength is better.Between two veneers that laterally arrange of every group of transition otic placode 12, also be provided with and strengthen connecting plate 14, two veneers are linked together, thereby the structural strength of enhancing transition otic placode 12 improves crossbeam transition assembly 20 stability and safetys afterwards are installed.
Undersetting 10 also comprises and encloses tube 15, is set with upper cover plate 16 enclosing tube 15 upper end, and the lower end is set with lower cover 17.The upper end of supporting leg 11 is fixedly installed on the upper cover plate 16, captives joint with lower cover 17 in the lower end, and passes lower cover 17 and stretch out.Between the extendible portion of supporting leg 11 and lower cover 17, reinforced rib can be set, to strengthen the Joint strenght between supporting leg 11 and the lower cover 17, the support strength of raising supporting leg 11.
Transition otic placode 12 and is separately positioned on each respective side of supporting leg 11 between upper cover plate 16 and lower cover 17, because the supporting construction of supporting leg 11 is comparatively firm, therefore, can guarantee that connected crossbeam transition assembly 20 also has firm supporting construction.At each supporting leg 11 and enclose tube and be set with 18, two leg splints 18 of two leg splints are symmetricly set on supporting leg 11 respectively along the line in the axle center of the center of supporting leg 11 and undersetting 10 both sides between 15.Propping up leg splint 18 has increased the Joint strenght that encloses between tube 15 and the supporting leg 11, has improved the support strength that encloses tube 15.
According to tower crane of the present invention; Comprise the frame that climbs, standard knot and undersetting assembly, the frame that wherein climbs is connected on the frame connector 21 that climbs of crossbeam transition assembly 20 of undersetting assembly, and standard knot is connected on the supporting leg 11 of undersetting 10 of undersetting assembly; When at standard knot supernumerary segment jacking state; The frame that climbs links to each other with crossbeam transition assembly 20, and when not at standard knot supernumerary segment jacking state, standard knot links to each other with supporting leg 11.
From above description, can find out that the above embodiments of the present invention have realized following technique effect: the undersetting assembly comprises undersetting, side attaching parts and is removably disposed in the crossbeam transition assembly on the attaching parts of side.When processing undersetting assembly of the present invention, can crossbeam transition assembly and undersetting be processed separately respectively, simplified manufacturing procedure, reduced tooling cost, also help guaranteeing finish size and precision more.Because crossbeam transition assembly is detachable, when transportation, can it be dismantled, thereby reduce taking up room of whole undersetting assembly, reduce transportation volume, reduce the freight.The side attaching parts is to be arranged on two transition otic placodes on the opposite flank; Two crossbeam transition assemblies are arranged on the transition otic placode; Realize and being connected of the frame that climbs through two crossbeam transition assemblies, reduced the overall weight of undersetting assembly, reduced its space hold.To extending below, boring adds and is prone to man-hour and guarantees size and precision the transition otic placode along the axial direction of undersetting.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
