Description
Technical field
Container spreader technical field is the utility model is related to, more particularly to a kind of container spreader parallel rod machine
Structure.
Background technology
Container spreader type of drive is broadly divided into hydraulic pressure and electronic two kinds.Parallel linkage is electric container sling
A kind of middle common mechanism for being used to drive twist lock, is arranged in container spreader both ends, motor passes through parallel four-bar linkage transmission
Torque actuated twist lock.With the development of container spreader technology, twist lock uses floating type twist lock, and floating type twist lock has 3 rotations
The free degree.Above-mentioned parallel four-bar linkage end is connected with twist lock, it is necessary to meet the floating type twist lock free degree.But in existing skill
In art, as Figure 1-3, the one end of first connecting rod 2 is connected by spherical plain bearing rod end with the first floating type twist lock 1, and the other end leads to
Spherical plain bearing rod end is crossed to be connected with motor rocking arm 3, while motor rocking arm 3 is connected with the rod end u shaped connector 4 of second connecting rod 5, second
The other end of connecting rod 5 is connected by oscillating bearing with the second floating type twist lock 6.Motor rocking arm 3 is under motor driving, rotation 90
Degree, the second floating type twist lock 6 is driven to complete 90 degree of actions by second connecting rod 5.The end of second connecting rod 5 in above-mentioned parallel linkage
Portion and the end of first connecting rod 2 can not all install oscillating bearing simultaneously on motor rocking arm 3, and mounting hole must be coaxial, and second
When connecting rod 5 is using rod end u shaped connector 4, rod end u shaped connector 4, which is connected first connecting rod 2 with motor rocking arm 3,4 frees degree；And the
Two connecting rods 5 only have 2 frees degree, can not realize multiple degrees of freedom.When swinging twist lock by force, oscillating bearing and connecting rod pine are easily caused
It is dynamic.Therefore 3 rotational freedoms of the first floating type twist lock 1 of the side of first connecting rod 2 connection only be can guarantee that.Reduce twist lock
Floating effect.
