The specific embodiment
Hereinafter also describe in conjunction with the embodiments the present invention in detail with reference to accompanying drawing.Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.
To shown in Figure 10, according to embodiments of the invention, lower support saddle component comprises undersetting 10, is provided with the side attaching parts at least two opposite flanks of undersetting 10, is provided with pin shaft hole on the attaching parts of side as Fig. 3.Undersetting 11 also includes the supporting leg 11 that stretches out from the below, and supporting leg 11 has the structure that is connected with the standard knot of tower crane.Lower support saddle component 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 by bearing pin and undersetting 10.Lower surface at crossbeam transition assembly is provided with climbing support attaching parts 21, and climbing support attaching parts 21 is connected by bearing pin with climbing support.Also can carry out detouchable by bolt or other connection structure between crossbeam transition assembly and side attaching parts is connected.The side attaching parts can for being removably disposed on undersetting 10, also can be fixedly installed on undersetting 10, such as being welded on 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 replace the function of supporting leg stock by the small and exquisite side attaching parts that is easy to process of structure and detouchable crossbeam transition assembly, not only make lower leg assembly be easier to processing, reduce manufacturing procedure, reduced tooling cost, and be convenient to guarantee finish size and the precision of each parts of lower support saddle component.Because crossbeam transition assembly is detachable, therefore, improved greatly the convenience of time leg assembly when transportation, 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, every two groups of transition otic placodes 12 are set in parallel in the same plane side, make transition otic placode 12 more simple and convenient with captiveing joint of undersetting 10, and be more convenient for crossbeam transition assembly 20 is arranged and installs.Preferably, transition otic placode 12 is perpendicular to its mounting plane.Removably be provided with 20, two crossbeam transition assemblies 20 of a crossbeam transition assembly and be arranged in parallel below every two groups of transition otic placodes 12, 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 carry out following process on the one hand perpendicular to mounting plane and along the axial direction setting of undersetting 10 after transition otic placode 12 arranges, guarantee finish size, position and the precision of pin shaft hole; On the other hand, make the force structure of transition otic placode 12 more reasonable, can bear larger vertical direction application force, increased the support performance of lower support saddle component.
Every group of transition otic placode 12 includes two veneers that be arranged in parallel, 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 coordinating with the upper ear plate 24 of crossbeam transition assembly 20, thus installation crossbeam transition assembly 20.Two pin shaft holes 13 are used in conjunction with, and make the crossbeam transition assembly 20 after connecting by bearing pin be difficult for swinging, and connection structure is stable, and support strength is better.Also be provided with between two veneers that be arranged in parallel of every group of transition otic placode 12 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 cylinder 15, is fixedly installed upper cover plate 16 enclosing cylinder 15 upper end, and the lower end is fixedly installed lower cover 17.The upper end of supporting leg 11 is fixedly installed on 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 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 cylinder and be fixedly installed 18, two leg splints 18 of two leg splints between 15 and be symmetricly set on respectively the both sides of supporting leg 11 along the line in the axle center of the center of supporting leg 11 and undersetting 10.Propping up leg splint 18 has increased the Joint strenght that encloses between cylinder 15 and supporting leg 11, has improved the support strength that encloses cylinder 15.
According to tower crane of the present invention, comprise climbing support, standard knot and lower support saddle component, wherein climbing support is connected on the climbing support attaching parts 21 of crossbeam transition assembly 20 of lower support saddle component, standard knot is connected on the supporting leg 11 of undersetting 10 of lower support saddle component, when at standard knot supernumerary segment jacking state, climbing support is connected with crossbeam transition assembly 20, and when not at standard knot supernumerary segment jacking state, standard knot is connected with supporting leg 11.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect: lower support saddle component comprises undersetting, side attaching parts and is removably disposed in crossbeam transition assembly on the attaching parts of side.When processing lower support saddle component of the present invention, crossbeam transition assembly and undersetting can be processed separately respectively, simplified manufacturing procedure, reduced tooling cost, also more be conducive to guarantee finish size and precision.Because crossbeam transition assembly is detachable, when transportation, it can be dismantled, thereby reduce taking up room of whole lower support saddle component, 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 climbing support by two crossbeam transition assemblies, reduced the overall weight of lower support saddle component, reduced its space hold.The transition otic placode is along the axial direction of undersetting to downward-extension, during Drilling operation easily with guarantee size and precision.
The above is only 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 modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
