Abstract
The utility model relates to a locking device for travel switches and specifically relates to a cam locking device provided with independently-adjusted locking units and used in travel switches, belonging to the field of travel switches. Eight mutually-independent locking units are arranged on a cam of the cam locking device. A locking screw of each locking unit is located on a radial end face of the cam and is used for independently adjusting the position of the locking unit. Any locking unit can be adjusted independently without moving other locking units so that the first locking unit is prevented from shifting to severely affect the precision in controlling a travel switch during adjustment of the second locking unit after the first locking unit is adjusted.
Description
Technical field
The utility model relates to a kind of travel switch locking device that is used for, specifically relate to a kind of have independent adjust locking unit be used for travel switch camlock device, it belongs to the travel switch field.
Background technology
Along with the development of lifting industry, its requirement to crane is also improving constantly.Travel switch is the visual plant of control crane, particularly controls the travel switch of crane lifting displacement.The present travel switch that generally uses, its camlock device is for utilizing axial friction locking, control all locking units by a locking nut, can't be implemented in and adjust one of them locking unit under the motionless situation of other locking units, and after adjusting first locking unit, when adjusting second locking unit, the phenomenon that first locking unit can be offset has a strong impact on the control precision of travel switch.
Summary of the invention
In view of the problem that prior art exists, the technical scheme that the utility model adopted is a kind of camlock device that is used for travel switch with independent locking unit.
To achieve these goals, the technical scheme that the utility model adopted is a kind of camlock device that is used for travel switch, and it comprises: a camshaft and N locking unit; Described camshaft passes locking unit, and locking unit is the axle rotation with the camshaft; It is characterized in that: described locking unit comprises band tooth axle, trip bolt and cam; Described cam is an annular, has through hole in the middle of it, and end face is provided with screw hole, and trip bolt matches with screw hole; Band tooth axle is positioned at through hole; Band tooth axle both sides are respectively equipped with pad; Described band tooth axle is a disc, and it has the through hole identical with the camshaft shape, and its cylindrical circumference is provided with the plurality of V connected in star.
Described screw hole number is 2.
Described N locking unit structure is identical, and N is 8.
The number of described V-type groove is 60.
Described pad is provided with the through hole identical with the camshaft shape.
Advantage of the present utility model is: cam is provided with 8 separate locking units, the lock-screw of each locking unit is positioned on its cam radial end face, it independently adjusts the position of each locking unit, can under the motionless situation of other locking units, adjust wherein any locking unit separately, avoid after adjusting first locking unit, when adjusting second locking unit, the phenomenon that first locking unit can be offset has a strong impact on the problem of the control precision of travel switch.
