Problems solved by technology

With the diversification of transported items, some items cannot meet the needs with general-purpose containers, and need to be transported through special transport boxes
In the prior art, the spreader suitable for container hoisting, the turning lock of the lifting point is driven by the power output end to drive the connecting rod mechanism to ensure the forward and reverse rotation of the turning lock. The invention patent application with the application number of 2011101690231 introduces a reciprocating straight line The moving motor drives the connecting rod and the revolving pin assembly. This technology solves the failure of the spreader caused by the inaccurate travel of the deceleration motor and the damage of the motor.
However, when the distance between the lifting points (twist locks) changes, the above-mentioned sling cannot be hoisted, and special slings need to be remade to achieve hoisting

Abstract

The invention discloses a driving mechanism of a variable distance turn lock of a special transport case lifting tool. The driving mechanism comprises a lead screw nut pair, two slide blocks, slide rails, two turn lock shafts, two turn lock shaft gears, a driving gear, a rack and rack guide supports, wherein nuts of the lead screw nut pair are fixedly arranged on the slide blocks; the slide blocks can move along the slide rails; the turn lock shafts are mounted at the lower ends of the slide blocks and can rotate on the slide blocks; the turn lock shaft gears are mounted on the turn lock shaft; the rack is a two-sided rack; the turn lock shaft gears are arranged on one side of the rack and engaged with the rack; the other side of the rack is engaged with the driving gear; the driving gear has no power input and is self-locked and static; the rack guide supports are arranged at the two ends of the rack; and the lead screw nut pair and the driving gear are connected with a power device. The driving mechanism of the variable distance turn lock of the special transport case lifting tool achieves a lifting task when the distance of lifting points of a container is changed; the lifting tool is not required to be replaced; and the service efficiency of the lifting tool is improved.

Description

technical field [0001] The invention belongs to the technical field of spreaders, and in particular relates to a variable-distance rotary lock driving mechanism of a spreader for a special transport box. Background technique [0002] Material flow is one of the important features of the globalization of world economy and trade, and container transportation is the main form of material flow. Container loading and unloading is achieved through container spreaders. There are several components on the container spreader that can be connected with the container - the twist lock, relying on the twist lock to rotate 90° in both directions to realize the connection and separation with the container. In the above-mentioned container hoisting operation, the box structure and the lock seats of the hoisting mechanism on it have been standardized, and the distance between the lock seats has clear regulations (no change). With the diversification of transported items, some items cannot ...
