The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 is the scheme drawing according to the tower crane load connecting device of the embodiment of the invention 1.As shown in Figure 1, this tower crane load connecting device comprises: vertical pedestal 1 is used for being connected to an outside vertical plane; The first bearing 2 is arranged on the facade of vertical pedestal 1; The second bearing 4 is arranged on the facade of vertical pedestal 1, is positioned at the top of the first bearing 2, and spaced apart with the first bearing 2; Bent axle attaching parts 3 comprises: vertical shaft section 31 be installed in rotation on the first bearing 2 and the second bearing 4, and crank portion 32, one ends are connected in vertical shaft section 31, and from vertical shaft section 31 horizontal-extendings, the other end forms suspended end.
In practical operation, vertical pedestal 1 can fix on the wall or other object on, in order to play fixation to whole tower crane load connecting device.Can articulate corresponding load on the crank portion 32.
Because bent axle attaching parts 3 is fixed on the vertical pedestal 1 by the first bearing 2 and the second bearing 4 these two strong points, thereby bent axle attaching parts 3 provides stable supporting role can for crank portion 32, even when being subject to axis with the bent axle attaching parts and having the power of angle, bent axle attaching parts 3 can not twist yet.
Further, the first bearing 2 and the second bearing 4 can be arranged in parallel.Like this, can in the certain situation of the material of the first bearing 2 and the second bearing 4, provide larger bearing force; Perhaps, in the situation of the required specified bearing force that provides, save the material of bearing.
Further, the first bearing 2 and the second bearing 4 are separately positioned on bottom and the top of vertical shaft section 31.Like this, can in the certain situation of the material of the first bearing 2 and the second bearing 4, provide larger bearing force; Perhaps, in the situation of the required specified bearing force that provides, save the material of bearing.
Here, the lower surface of the second bearing 4 has groove, and the upper end of vertical shaft section 31 is installed in this groove, in order to form a fixed connection between the second bearing 4 and vertical shaft section 31.
The below is described in detail the principle of work of the tower crane load connecting device of present embodiment.
Lower in working order, articulate the load that remains to be fixed on the crank portion 32, vertical pedestal 1 is fixed on the metope.As shown in Figure 3, be connected with the bottom of vertical pedestal 1 by the first bearing 2, form the first fulcrum in the position of the first bearing 2, in order to bent axle attaching parts 3 is supported.Equally, be connected with the top of vertical pedestal 1 by the second bearing 4, formed the second fulcrum in the position of the second bearing 4, in order to bent axle attaching parts 3 is further supported.
Because the effect of load, one end of bent axle attaching parts 3 may be subject to the effect of load force F1 and F2, wherein F2 can be the power that the axis direction with bent axle attaching parts 3 neutral axial regions 31 forms an angle, the power that F1 can be parallel with the axis direction of bent axle attaching parts 3 neutral axial regions 31.Owing to there be simultaneously the first fulcrum and the second fulcrum that supports bent axle attaching parts 3, thereby bent axle attaching parts 3 can not twist, the parts of load connection carry load can run-off the straight or deformation yet, therefore, guaranteed that tower crane load connecting device can stably accept load, prolonged the service life of self.
Can assemble in the following manner the tower crane load connecting device in the present embodiment, it comprises:
S11 is installed on the fixed block 21 in the first bearing 2 and the second bearing 4 on the vertical pedestal 1.
S12 links to each other compact heap 22 usefulness screws with the screw of fixed block 21, keep compact heap to be in relaxed state this moment.
