Telescopic container lifting tool with follow-up support ring

Abstract

The invention discloses a telescopic container lifting tool with a follow-up support ring. The telescopic container lifting tool comprises a main beam, a left telescopic beam and a right telescopic beam, wherein the main beam is a single master cylinder structure; the left telescopic beam and the right telescopic beam are respectively sleeved on two sides of the inside of the main beam; the innerend of the left telescopic beam is in sliding fit with the main bean through the follow-up support ring; a left telescopic beam end single-hook support structure is arranged at the inner end of the left telescopic beam and is matched with the follow-up support ring; the inner end of the right telescopic beam is in sliding fit with the main beam through a right telescopic beam end single-hook support structure; the left telescopic beam can slide in the right telescopic beam by controlling the left telescopic beam to stretch and contract. According to the telescopic container lifting tool, the follow-up support ring is arranged; a single hook is designed on each of a left telescopic beam end support of a right telescopic beam end support; through double-hook ingenious contact between the single hook on each end support and a U-shaped double-hook structure of the follow-up support, the harm of the additional torsion force of the lifting tool is eliminated; the thickness of steel plates manufactured by the lifting tool is reduced; the lifting tool is light and reliable; the cost is reduced.

[0002] Telescopic container spreader, as a kind of lifting equipment, has its unique advantages. It can quickly switch from lifting 20-foot boxes to lifting 40-foot boxes; the existing telescopic container spreader, the main beam is (only is) a double-tube structure, the left and right telescopic beams slide in their respective main tubes, when the spreader changes from 20 feet to 40 feet, the left and right telescopic oil cylinders respectively push the respective telescopic beams to extend outward; the ends of the telescopic beams The end beam is connected with an asymmetric structure. Under the two ends of the end beam, there is a set of turn lock mechanism. When the spreader is working, it uses four sets of turn locks to hang the four corners of the container to make it rise smoothly. drop; because if the single-tube structure is adopted, that is: the main beam covers the right beam, and the right beam covers the left beam, when the switch from 20 feet to 40 feet, the end of the left telescopic beam has been separated from the inner cavity of the right telescopic beam, resulting in no The problem that the spreader cannot be used due to the support at the place

It can be seen from this that the main beam of the existing telescopic spreader adopts a double-tube structure. When hanging heavy objects with locks, due to the asymmetry of the structure, a harmful additional torsional moment will inevitably be generated on the telescopic beam. This additional torque directly poses a hazard to the stability of the telescopic beam and the main cylinder, resulting in a large spreader structure. , the plate thickness increases, the cost increases
