Description
Technical field
The utility model belongs to a kind of levelling device, the random locking device of especially a kind of levelling gear.
Background technique
Existing levelling gear, comprise fixed base, fixed base and the turntable frame above it hinged, the side of fixed base is provided with adjustment oil cylinder, adjustment oil cylinder in piston rod upper end and turntable frame one end hinged, the opposite side of fixed base is provided with locking plate, and the upper end of locking plate is fixedly connected with the turntable frame the other end, and locking plate is provided with limes superiors locking hole, neutral position locking hole and limit inferior locking hole; During work, piston rod in oil cylinder promotes after turntable frame rotates to and need leveling position, to be coordinated and locks, but there is following problem by the locking hole on locking plate with lock pin; 1. the structural limitations turntable frame leveling angular range of locking plate; 2. during the leveling of turntable frame, locking hole needs corresponding with lock pin, can only in upper extreme position or lower limit position or neutral position locking, and turntable cannot accomplish that " level " locks and leveling work length consuming time, brings potential safety hazard to equipment on turntable.
Summary of the invention
The utility model provides a kind of levelling gear random locking device, solves the problem that little, the consuming time length of levelling gear leveling angular range in prior art, Security are low, and improves leveling precision.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the random locking device of a kind of levelling gear, comprise fixed base, fixed base and the turntable frame above it hinged, the side of fixed base is provided with the adjustment oil cylinder that can adjust and turn gantry rotational angle, adjustment oil cylinder in piston rod upper end and turntable frame one end hinged, it is characterized in that: the opposite side of fixed base is provided with the key seat be fixedly connected with, bulb bearing pin is provided with in key seat, the upper end of bearing pin is provided with bulb, bulb is connected with the ball cup above it, it is secondary that bulb and ball cup form the higher ball motion of degrees of freedom, the upper end of ball cup is fixedly connected with the leading screw lower end of top, the upper end of leading screw is connected with the screw be arranged on the turntable frame the other end, key seat is provided with locking hole, is provided with lock pin in locking hole, and lock pin carries out locking by cylinder to bulb bearing pin.
Bulb described in technique scheme and ball cup can replace with Hooke's joint, and Hooke's joint has the higher feature of degrees of freedom, thus increase this device leveling angular range.
Beneficial effect: the utility model has the following advantages: 1. ball motion pair has the higher feature of degrees of freedom, thus increases this device leveling angular range; 2. lead screw pair has that precision is high, the feature of working stability, thus improves this device leveling precision; 3. lock pin carries out locking by cylinder to bulb bearing pin, improves Security; 4. the vertical position that the utility model utilizes lead screw pair to carry out within the scope of maximum difference of height compensates, ball motion pair is utilized to carry out angle compensation, mechanical force is utilized to carry out locking, thus reach the target of arbitrary position safety locking, prevent because misoperation brings insecurity, also no longer need manually to guard horizontal position change.
