Description
Technical field
The utility model relates to the controller of hoisting crane.
Background technology
The master controller of hoisting crane is a kind of frequent executive component connected circuit and cut off; be widely used in the control system of various elevator machinery; belong to the little but complex structure of volume; accuracy of manufacture requires high accessory; for big machinery; this kind of accurate accessory of master controller shows slightly coarse in Design and manufacture, such as Chinese patent CN201220333729, does not usually consider the protection problem to inner member when designing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of master controller of hoisting crane, and its structure is exquisiter, can play better protective effect to inner member.
The technical scheme that the utility model technical solution problem adopts is: a kind of master controller of hoisting crane, comprise quadrangle box and handle, cross rotating shaft is provided with in described quadrangle box, described cross rotating shaft comprises axle and lower shaft, described upper axle is mutually vertical with lower shaft, described handle stretches in described quadrangle box from the top of described quadrangle box, and be connected with lower shaft through upper axle, described upper axle and lower shaft stretch out from adjacent two surfaces of described quadrangle box respectively, the outer end of described upper axle and lower shaft is connected to rotation box, described rotation box can rotate with described upper axle and lower shaft, also rotating shaft protective sleeve is provided with between described rotation box and described quadrangle box, rotating shaft protective sleeve is fixedly connected on the outside face of quadrangle box, sealed bearings is provided with between described rotating shaft protective sleeve and described rotation box, the lower surface both sides of described rotation box have symmetrical inclined-plane, described inclined-plane is provided with multiple parallel contact-box, described contact-box is provided with contact, described quadrangle box upper surface is provided with protective case base, described protective case base is provided with protective case, the upper end of described handle is provided with operating head, described operating head envelopes outside and the end of described handle, described operating head is provided with action button, the upper end of described protective case is fixedly connected on the lower end of described operating head, and the lower end of described protective case is fixedly connected on described protective case base, and described protective case has certain deformability.
While employing technique scheme, the utility model can also adopt or combine and adopt further technical scheme:
Described protective case adopts rubber or leather material to make, and which is provided with sieve or fold texture.
Described operating head adopts plastics or plastic material to make.
The beneficial effects of the utility model are: master controller of the present utility model is at compact conformation, except promoting to some extent in transmission accuracy and contact commonality, the utility model is in design from point protection considered inner precision element, the part of stretching out quadrangle box at transmission shaft is provided with rotating shaft protective sleeve and rotation box, guarantee that inner member is isolated with air and other external environmental factors that may affect, protective case covers quadrangle box upper surface from operating head lower end always, in the metallic member of whole handle is coated on, when metal handle is pulled, certain deformation can be there is in protective case along with the direction of pulling of metal handle, except increasing engage a gear feel, more can protect metal wherein and driver element, increase the service life, guarantee transmission accuracy.
