Fig. 8 A is a block diagram of schematically representing above-mentioned car 40, and Fig. 8 B is the lateral plan of the action when schematically representing the up-down of car 40.Below, with reference to these figure the lifting action of car 40 is described.For example, under the situation that the car 40 that is positioned at lowering position is risen, the motor 24 of the lower end of two column 20A, 20B is driven to direction rotation, the straight moving guiding element 42 that will be connected in the upper end of both sides module 28A, 28B by chain 23 draws high to the top.Thus, car 40 by straight moving guiding element 42 and along two guide rail 26A, 26B is directed and rise to set height.
In addition, under the situation that car 40 is descended, motor 24 contrarotations are driven.Thus, car 40 by straight moving guiding element 42 and along two guide rail 26A, 26B is directed and drop to set height.
At this moment, the directly moving guiding element 42 of each of the both sides of the X-direction of car 40 is limited with omnidirectional the moving of the bearing of trend quadrature of guide rail 26A, 26B, moves along guide rail 26A, 26B.But; Under the situation of the error of parallelism that has two guide rail 26A, 26B and straightness accuracy etc.; By the globe bearing 43, the 43S that are clipped between each directly moving guiding element 42 and the car 40 ( side form piece 28A, 28B), each directly moves suitable bending between guiding element 42 and the car 40 and allows the relative yaw of each directly moving guiding element 42 with respect to car 40.And, in car 40 sides, according to the posture of two guide rail 26A, 26B and shape variation and automatically regulate side form piece 28A, 28B binding angle with respect to pedestal module 27 by globe bearing 35.And, by the axial slip of the slide bushing in the globe bearing 43S 54, allow the relatively moving of the straight moving guiding element 42 that on X-direction, leaves configuration of the change of the separating distance that is accompanied by two guide rail 26A, 26B with respect to fulcrum pin 41.
As above, in this tower crane SC, the straight moving guiding element 42 that is sticked in each guide rail 26A, 26B is linked to cooresponding side form piece 28A, the 28B of car 40 via globe bearing 43,43S.And the lower end of each side form piece 28A, 28B and the end of pedestal module 27 can link via globe bearing 35 rotationally.Therefore; Even because the error of the parallelism of two guide rail 26A, 26B and straightness accuracy etc. and produce warpage or crooked etc. attitude change and alteration of form, also can realize based on allowing of the yaw of the straight moving guiding element 42 of globe bearing 43,43S and allowing of lower end and rotation pedestal module 27 of side form piece 28A, 28B at two guide rail 26A, 26B.Thus, can prevent in advance that big stress is in directly moving between guiding element 42 and guide rail 26A, the 26B.
In addition, in this tower crane SC, in the globe bearing 43S of the lower end of car 40, be provided with slide bushing 54 (slide mechanism).Therefore, under the situation of the separating distance of two guide rail 25A, 26B change, slide mechanism absorbs should distance change, can prevent that the N/R stress is in directly moving guiding element 42.
In addition, in this tower crane SC, car 40 integral body are not the integrated modules of rigidity.This car 40 by carry put the pedestal module 27 of shifting apparatus 100 and via chain 23 by the go up and down side form piece 28A, the split component set-up of 28B of both sides of driving of motor 24, the lower end of each side form piece 28A, 28B and the end of pedestal module 27 link via globe bearing 35.Therefore; Because the error of the parallelism of two guide rail 26A, 26B and straightness accuracy etc. and existing between guide rail 26A, the 26B and under local warpage or the crooked situation car 40 is carried out under the situation of lifting action can prevent in advance that also the N/R stress is in car 40.
With reference to Fig. 9 concrete example is described.The figure of action that Fig. 9 is the guide rail 26A that schematically representes both sides, 26B when the middle section of above-below direction leaves ground crooked (warpage) most and becomes arcuation, car 40 and straight moving guiding element 42.Shown in the solid line among this figure, under the situation below car 40 is positioned at more than the middle section of guide rail 26A, 26B, the straight moving guiding element 42 that is connected in the top of side form piece 28A, 28B follow guide rail 26A, 26B outside bending and laterally direction move.As a result, each side form piece 28A, 28B are that the center is outward-dipping with respect to pedestal module 27 and with globe bearing 35.In addition, shown in the imaginary line among this figure, in the time of above car 40 is positioned at more than the middle section of guide rail 26A, 26B, the straight moving guiding element 42 that is connected in the top of side form piece 28A, 28B follow guide rail 26A, 26B inside bending and to the inside direction move.As a result, each side form piece 28A, 28B are that the center slopes inwardly with respect to pedestal module 27 and with globe bearing 35.So along guide rail 26A, when 26B goes up and down, side form piece 28A, 28B flexibly fascinate with the part of the bending that absorbs guide rail 26A, 26B at car 40, thereby do not produce N/R stress in each one of car 40.Promptly; In this tower crane SC; Be not accompanied by the lifting action of car 40 and produce the elastic deformation that stress caused, thereby can prevent in advance that the big load that counteraction caused of elastic deformation from acting on straight moving guiding element 42 and guide rail 26A, 26B sharp at car 40.In addition; Under the situation of this embodiment; When the lifting action of car 40; Follow the warpage of guide rail 26A, 26B or crooked and when fascinating at side form piece 28A, 28B, be connected in slide bushing 54 (slide mechanism) the automatically regulating both sides module 28A, the separation width of 28B of globe bearing 43 of the bottom of car 40.This function also helps to obtain the lifting action of car 40 smoothly.
So,, can suppress the situation of N/R stress in straight moving guiding element 42 according to this tower crane SC.Therefore, can not cause the following degradation undesirable condition ground in life-span to adopt dust or the few straight moving guiding element 42 of vibrating noise.
In addition, in this tower crane SC, only the distolateral globe bearing 43S in the X-direction of car 40 is provided with slide mechanism (slide bushing 54).Therefore, can there be the column 20A (guide rail 26A) of a side of slide mechanism to be maintained certain distance all the time the position distance of the shifting apparatus on the car 40 100.That is, can correctly manage the position of the shifting apparatus 100 that is arranged at car 40 all the time.
In addition, in this tower crane SC, the side form piece 28A of car 40, the upper end of 28B and bottom are sticked in cooresponding guide rail 26A, 26B via straight moving guiding element 42 respectively.Therefore, can make the side form piece 28A of both sides, 28B flexibly follow guide rail 26A, 26B all the time, can make the pedestal module 27 of car 40 stably remain in guide rail 26A, 26B.
In addition, under the situation of this tower crane SC, between the directly moving guiding element 42 of car 40 and each by globe bearing 43,43S can crooked mode linking.Therefore, in mobile when beginning of tower crane SC and move when stopping, during the action of shifting apparatus 100 etc., can be easily and correctly calculate the load that acts on straight moving guiding element 42.This be because, mobile when beginning of tower crane SC and move the X-direction that produces when stopping load, and the load of the Y direction that produces during action at shifting apparatus 100 without moment act on globe bearing 43,43S part.So, can set the intensity of straight moving guiding element 42 and guide rail 26A, 26B etc. rightly.
