Double-lifting-pin lifting tool for avoiding flat rack container dropping accident

Abstract

The invention relates to a double-lifting-pin lifting tool for avoiding a flat rack container dropping accident. The double-lifting-pin lifting tool comprises a tapered end, a spin lock arranged on a container body and two lifting pin mechanisms, wherein the spin lock is provided with the two lifting pin mechanisms located on positions symmetrical relative to the central line of the tapered end to form a double-lifting-pin structural form; and a detecting and limiting device is arranged beside each lifting pin mechanism and is connected in series with each lifting pin in a limiting way to realize interlocking control. Each lifting pin mechanism comprises a lifting pin, a limiting induction block, a guide fixed block and a spring, wherein the upper part of the lifting pin passes through an upper container body, the lifting pin is provided with the guide fixed block and the limiting induction block, a step-link shaft at the lower part of the lifting pin is provided with the spring and is locked and fixed by using a nut, one end of the spring is in contact connection with the upper container body, and the other end of the spring is in contact connection with a boss of the step-link shaft of the lifting pin. Due to the additional arrangement of implantation pins of a tyre crane lifting tool and an implantation limiting method, the locking condition of a mounted / dismounted flat rack container of the tyre crane lifting tool is increased, the occurrence rate of error locking is reduced, and the operation safety rate and operation efficiency of equipment are increased.

Description

technical field [0001] The invention relates to a frame container, in particular to a spreader used to prevent the frame container from falling. Background technique [0002] In recent years, the workload of frame containers (hereinafter referred to as frame containers) has been increasing. The frame box is a special container with the roof and side walls removed on the basis of ordinary containers, leaving only the bottom plate, end walls and four corner columns. It is suitable for loading ultra-wide, ultra-high and heavy goods. The complex and irregular shape plays an important role in the transportation of over-standard containers. [0003] The value of the goods loaded in the frame box is high, and special attention must be paid when loading. Each container terminal has taken certain safety measures, but the accident of the frame box falling has not been completely resolved, which has a great impact on the production and operation company, the safety of operators and eq...
