To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 2 and Fig. 3, the utility model provides a kind of leg assembly, and it is applied in the hoisting crane.This leg assembly comprises horizontal support legs and the vertical leg that is connected with this horizontal support legs; Wherein, The extended line of the extended line of the central axis of this horizontal support legs and the central axis of this vertical leg is non-intersect, promptly is formed with side-play amount between the extended line of the central axis of the extended line of the central axis of this horizontal support legs and this vertical leg.Concrete structure is following:
This leg assembly comprises chassis 2, left branch leg and the right supporting leg of hoisting crane.
This chassis 2 is provided with a bridge 21 and two bridges 22.
This left branch leg and should right side supporting leg be fixed on this chassis 2 and between this bridge 21 and this two bridge 22.Wherein, this left branch leg is adjacent to this two bridge 22, contiguous this bridge 21 of this right side supporting leg.
See also Fig. 4 to Fig. 6, this left branch leg comprises the vertical movable supporting legs 34 in left horizontal support legs case 31, left horizontal anomalous movement supporting leg 32, left vertical leg case 33 and a left side.This left side horizontal support legs case 31 comprises first end 311 and and these first end, 311 second opposed end 312.This left side horizontal anomalous movement supporting leg 32 stretches into this first end 311 and telescopically is arranged in this left side horizontal support legs case 31.This left side vertical leg case 33 is fixed on the end of this left side horizontal anomalous movement supporting leg 32.Vertical movable supporting legs 34 telescopicallies in this left side are arranged in this left side vertical leg case 33.
This right side supporting leg is identical with the structure of this left branch leg, and this right side supporting leg comprises right horizontal support legs case 41, right horizontal anomalous movement supporting leg 42, right vertical leg case 43 and right vertical movable supporting legs 44.This right side horizontal support legs case 41 comprises first end 411 and and these first end, 411 second opposed end 412.Matching relationship between each element of this right side supporting leg is identical with matching relationship between each element of this left branch leg, so do not give unnecessary details.
This left branch leg and this right side supporting leg are welded in one and are fixed on this chassis 2.Particularly; This left side horizontal support legs case 31 is welded in one with this right side horizontal support legs case 41 and is fixed on this chassis 2; And second end 312 that should left side horizontal support legs case 31 relatively should right side horizontal support legs case 41 first end 411 be provided with indentation amount S; Correspondingly, first end 411 that second end 412 of this right side horizontal support legs case 41 relatively should left side horizontal support legs case 31 also is formed with indentation amount (figure is mark).Also can think: this left side horizontal support legs case 31 is provided with indentation amount S away from the end that an end of this left side vertical leg case 33 relatively should right side horizontal support legs case 41 be provided with right vertical leg case 43, and this right side horizontal support legs case 41 is provided with indentation amount (figure is mark) away from the end that an end of this right side vertical leg case 43 relatively should left side horizontal support legs case 31 be provided with left vertical leg case 33.
This left side horizontal anomalous movement supporting leg 32 moves the permanent seat 321 that is formed for fixing this left side vertical leg case 33 away from an end of this left side horizontal support legs case 31 to these right side horizontal support legs case 41 1 lateral deviations, thereby makes the center of this permanent seat 321 form side-play amount P1 with respect to the line of centers of this left side horizontal anomalous movement supporting leg 32 to a side of this bridge 21.Therefore, this permanent seat 321 with respect to this left side horizontal anomalous movement supporting leg 32 away from this two bridge 22, thereby can avoid the vertical movable supporting legs 34 of this a left side vertical leg case 33 and a left side to interfere with this two bridge 22.
Likewise; This right side horizontal anomalous movement supporting leg 42 moves the permanent seat 421 that is formed for fixing this right side vertical leg case 43 away from an end of this right side horizontal support legs case 41 to these left side horizontal support legs case 31 1 lateral deviations, thereby makes the center of this permanent seat 421 form side-play amount P2 with respect to the line of centers of this right side horizontal anomalous movement supporting leg 42 to a side of this two bridge 22.Therefore, this permanent seat 421 with respect to this right side horizontal anomalous movement supporting leg 42 away from this bridge 21, thereby can avoid this right side vertical leg case 43 and right vertical movable supporting legs 44 to interfere with this bridge 21.
Preferably, center from the line of centers of this left side horizontal anomalous movement supporting leg 32 a to side of this bridge 21 that form side-play amount P1 and this permanent seat 421 with respect to, the center of this permanent seat 321 equates to the side formation side-play amount of this two bridge 22 with respect to the line of centers of this right side horizontal anomalous movement supporting leg 42.
The permanent seat 321,421 of the leg assembly sieve of the utility model is formed with side-play amount with respect to the line of centers of this left side horizontal anomalous movement supporting leg 32, this right side horizontal anomalous movement supporting leg 42 respectively; Therefore can avoid left and right supporting leg and this bridge 21 and two bridges 22 to interfere; Need not operating personal leg assembly is carried out the adjustment of angle, thereby improved the efficient of construction operation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
