Abstract
The utility model relates to an overload protective device for a gantry lifter, which belongs to an auxiliary safety protective device of a gantry lifter for construction. The utility model is composed of a moving hoister base, an overload spring and a limit switch, wherein, one end of the hoister base is hinged on a fixing base by a hinged support of a hoister, and the other end is positioned right below the limit switch. The hoister base is pressed and stuck on the fixing base by the overload spring.
Description
The utility model belongs to the auxiliary security fender guard of a kind of building operation with arch type lifter.
Arch type lifter is the material vertical transport facility that a kind of building operation is used, and in its operational process, the overload phenomenon is run into by regular meeting.During overload, may cause wire cable rupture and the accident that meets accident on the one hand, the winch motor is burnt out because of overload.
The purpose of this utility model is to provide a kind of overload protection device of arch type lifter.
The purpose of this utility model is achieved in that the arch type lifter overload protection device; winch base, overload spring and limit switch by activity are formed; winch base one end is articulated in fixedly on the support by the winch hinged-support; its other end is under the limit switch, and the winch base is overlayed on fixing support by overload spring.
The utility model is simple in structure, and controller performance is reliable, and arch type lifter is had overload protection ability preferably.
Description of drawings:
Fig. 1 is an arch type lifter overload protection device structural representation
Below in conjunction with accompanying drawing the utility model is further described: the arch type lifter overload protection device; winch base 1, overload spring 2 and limit switch 3 by activity are formed; winch base 1 one ends are articulated in fixedly on the support by winch hinged-support 4; its other end is under the limit switch 3, and winch base 1 is overlayed on fixing support by overload spring 2.The carrying capacity of elevator is limited by overload spring 2.
Principle of work of the present utility model is as follows: when elevator transshipped, pull of steel wire surpassed the load capacity that overload spring 2 limits, and overload spring 2 is compressed, the movable end of winch hinged-support 4 is upwards lifted, prop up limit switch 3, thereby cut off the winch power supply, winch is shut down.
