Detailed description of the invention
A kind of lifting weight limitor as shown in Figure 2, comprises elastic deformation frame, and elastic deformation frame has the cantilever that two relative spacings are arranged, and is also provided with the deformation space for the crimp of elasticity Deformable rack 9 between two cantilevers on elastic deformation frame 9.Two above-mentioned cantilevers projecting end on be also separately installed with micro-switch 10 and corresponding with micro-switch arrange press head, when elastic deformation frame 9 effect of being squeezed arrives maximum distortion place (i.e. end position), the touched head pressure in contact of micro-switch 10.
In the present embodiment, pressing spinning freight weight limit adjust bar 8 on the cantilever residing for head, the tail end of freight weight limit adjust bar stretches into deformation space and is formed and above-mentioned press head.Certainly, in other embodiments, the above-mentioned head that presses can also be the ball bumps be installed on cantilever.
Above-mentioned elastic deformation frame 9 is U-shaped, two U-shaped linear arm form two above-mentioned cantilevers, the projecting end of one of them linear arm is provided with through hole for holding micro-switch 10 and for by removable for micro-switch 10 connecting bore be arranged on this linear portion, the projecting end of another linear arm is provided with for the tapped bore with above-mentioned freight weight limit adjust bar 8 threaded engagement, the axis of above-mentioned through hole and the dead in line of tapped bore, the space between two linear arm forms above-mentioned deformation space.The maximum hoisting weight that this lifting weight limitor regulates lifting weight limitor to allow by regulating the freight weight limit adjust bar distance stretched between the tail end of deformation space and the contact of micro-switch.
A kind of suspension transferring machine as shown in Figure 3-4, comprise base 1, base 1 is installed with column, the upper end of column is provided with main arm 6 and the hold-down arm 5 for supporting main arm 6, and hold-down arm 5 is arranged on the below of main arm 6, and the projecting end of hold-down arm is installed on main arm 6, hold-down arm is divided into two joints, between two joint hold-down arms, serial connection is provided with lifting weight limitor, and the structure of lifting weight limitor is consistent with the structure of the lifting weight limitor shown in Fig. 2, does not repeat them here.
Two joint hold-down arms are linked together by above-mentioned two cantilevers by above-mentioned elastic deformation frame 9.Certainly, in other embodiments, can also arrange lifting weight limitor at the fixed end of hold-down arm with being connected in series between column, one of them cantilever of above-mentioned elastic deformation frame 9 is connected with the fixed end of hold-down arm, and another cantilever is connected with column.Two above-mentioned cantilevers are the coupling end be connected with the distortion arm on suspension transferring machine during handling, it is again the installation end pressing head and micro-switch, and above-mentioned deformation space is also arranged between two cantilevers, make the structure of this lifting weight limitor simpler, compact like this, be convenient to production and processing.
The present embodiment in use, first according to the rated load of lifting, screws the distance between contact that freight weight limit adjust bar 8 regulates freight weight limit adjust bar 8 and micro-switch 10 with spanner.Then lifting is started, when the main arm 6 of suspension transferring machine is stressed, hold-down arm 5 is subject to downward pressure, the squeezing action that elastic deformation frame 9 is subject to hold-down arm produces crimp, two U-shaped linear arm are drawn close mutually, drive the freight weight limit adjust bar 8 that is arranged on respectively in two U-shaped linear arm and micro-switch 10 close to each other.When the weight of handling exceedes rated load, elastic deformation frame 9 reaches maximum distortion place by the squeezing action of hold-down arm, freight weight limit adjust bar 8 touches the contact of micro-switch, micro-switch cuts off the rising circuit of lifting motor 2 by relay, thus reach the object preventing suspension transferring machine from overloading, after handling weight puts down, elastic deformation frame 9 recovers original shape, two cantilevers are returned to initial position, and drive freight weight limit adjust bar 8 and micro-switch mutually away from.
It is more than preferred embodiment of the present utility model, in other embodiments, above-mentioned freight weight limit adjust bar can also be push rod and the spinning socket head cap screw at push rod afterbody, the respective cantilevered of above-mentioned elastic deformation frame offer for the macropore for push rod slip with for the threaded apertures with socket head cap screw threaded engagement, during use, rotate socket head cap screw with inner-hexagon spanner, socket head cap screw promotes the position that push rod arrives setting; Above-mentioned elastic deformation frame is not limited to U-shaped structure, can also be other version, but must possess the cantilever of two relative spacings settings, as H type structure.Certainly, those skilled in the art also can in varied situations, and carry out equivalent replacement according to the design general knowledge of this area, it is all within protection domain of the present utility model.
