The pincers leg other end be connected through the hinge respectively with axle B, described axle B is fixed with described casing, and described sliding block is provided with
Meet and discuss, described box inside installs limit switches, the described axle A other end is provided with handwheel, and described motor is installed
There is the time relay.
Beneficial effect：
1. the utility model is related to a kind of constant-moment type manual and electric double-purpose rail tongsrail clamp, its torque motor is by transmission device by power
Two-way leading screw is passed to, and by driving two and the sliding slider with two-way leading screw from two-way leading screw so that cut with scissors with sliding block
The two pincers legs connect complete the clamping or release action of pincers leg around fixed-axis rotation, and two-way leading screw is filled with handwheel and Stroke Control
Put, cross slide-bar mechanism is carried on casing, its link is hinged with fixed arm with transverse axis, is hinged with the longitudinal axis with casing.This practicality
New have a stable clamping force, scene be not required to be clamped debugging and can automatic centering, be widely used in crane, charging crane etc.
Large-scale rail mounted walking arrangement.
The utility model is related to a kind of constant-moment type manual and electric double-purpose rail tongsrail clamp, and described sliding block, which is provided with, meets and discusses, described case
Limit switches are installed in internal side, can effectively control the clamping stroke of constant-moment type manual and electric double-purpose rail tongsrail clamp.
The utility model is related to a kind of constant-moment type manual and electric double-purpose rail tongsrail clamp, and cross slide-bar mechanism can ensure rail tongsrail clamp and chassis
