Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated; but the scope that the utility model is protected is not limited in following specific embodiment, the amendment made when those skilled in the art are without the need to paying creative effort, equivalent replacement, improvement etc. all should be worked as and be belonged to protection domain of the present utility model.
As depicted in figs. 1 and 2, light-duty Pillar-fixing Type Slewing Crane described in the utility model, comprises column 1, crossbeam 2, girder dolly 3, electric block 4 and swing type mechanism 5; Described swing type mechanism 5 is arranged on the upper end of column 1; One end of described crossbeam 2 is connected with swing type mechanism 5, and its other end is free end, and crossbeam 2 can be made to horizontally rotate by swing type mechanism 5; The cross-sectional plane of described crossbeam 2 is in " C " shape mirror image that Open Side Down, and the opening part left and right sides is provided with the orbital segment 21 of the roller rolling for girder dolly 3; Described girder dolly 3 is arranged on crossbeam 2, and can along crossbeam 2 longitudinal sliding motion; Described electric block 4 is arranged on girder dolly 3.
Wherein, so-called light-duty, refer to hoisting crane described in the utility model, it is mainly used in the article lifting by crane or carry lighter in weight, and its hoisting weight is generally no more than 1250kg.This type of hoisting crane, generally can adopt the structure of vertical columns and swing-arm type.
In the utility model, by controlling the rotation of swing type mechanism 5, the rotation of crossbeam 2 can be controlled, and then realize handling article operation in certain fan angle range.Further, by arranging corresponding swing type mechanism 5, can realize the operation in different fan-shaped range, crossbeam 2 even can reach the rotating range of 270 °.
In addition, under normal circumstances, for controlling the rotation of swing type mechanism 5, the movement controlling girder dolly 3 and the action that controls electric block 4 all controls by controller 8, and controller 8 can as shown in fig. 1, be freely suspended in below electric block 4 by cable.
In addition, in order to improve the counter-bending deformation of crossbeam 2, as shown in fig. 1, also comprise oblique pull beam 6, described oblique pull beam 6 is obliquely installed, and one end of oblique pull beam 6 is connected with swing type mechanism 5, and the other end of oblique pull beam 6 is connected with the free end of crossbeam 2.
In addition, as further preferably arranging, the two ends of crossbeam 2 can be provided with stop mechanism 7.The effect of stop mechanism 7 is the stroke range for limiting girder dolly 3.
Consider when handling article, the weight of article and electric block 4 etc. is all applied on the orbital segment 21 of both sides in crossbeam 2 by the roller of girder dolly 3, like this, often causes crossbeam 2 that certain deflection occurs, cause the opening of crossbeam 2 to become large, be unfavorable for the movement of girder dolly 3; Certain deflection can be pre-set for this reason.Such as shown in Fig. 2, the orbital segment 21 of the described crossbeam 2 upper shed place left and right sides respectively to open centre direction horizontal by being tilted to lower setting.Further, the span that usually preferably can arrange the tilt angle theta of orbital segment 21 is 1 ° to 5 °.
