Automatically-released hoist ring and combined loading and unloading frame with same

Abstract

The invention discloses an automatically- released hoist ring and a combined loading and unloading frame with the same. The automatically-released hoist ring comprises a body, the upper end of the body is hinged to a connecting chain and a connecting ring, the lower end of the body is hinged to a snap ring, a two-stepped mounting hole is arranged in the body, an elastic device is arranged in the mounting hole and comprises a spring and a pull rod, the upper end of the pull rod penetrates through the spring and extends out of the body from the upper end of the mounting hole, and a nut lifting ring is arranged at a position, extending out of the body, of the upper end of the pull rod. By the aid of the automatically-released hoist ring, a flexible container and a lifting device are manually operated only at a lifting end, and unloading is automatically performed at an unloading end without manual operation. Compared with the prior art, the automatically- released hoist ring greatly improves transfer efficiency, saves labor by half, and avoids the influence of a severe working environment at the unloading end on physical and mental health of workers. In addition, the combined loading and unloading frame overcomes the defect that shipment cannot be realized once as a large freighter with a wide deck has dead angles.

Description

technical field [0001] The invention relates to a loading and unloading tool, in particular to an automatic detachable hoisting ring and a combined loading and unloading frame with the detachable hoisting ring. Background technique [0002] From ancient times to the present, it is the customary way to pack powdery and granular goods in small bags. It has been packed in sacks, cloth bags, and now the most common woven bags. It was only in the 1900s that cranes were generally installed at port terminals to lift and transfer bagged materials, and to transfer them in bulk. [0003] In today's society, bagged goods are increasing day by day. For now, a large number of bagged goods are still transported in conventional bulk packaging, which is far from meeting the needs of social development. Because every transshipment link of bagged goods in bulk transshipment needs to be reassembled and hoisted, this operation mode consumes a lot of labor, is labor intensive, pollutes the envi...

AI Technical Summary

Problems solved by technology

[0008] In view of the above problems, the present invention designs an automatic detachable hoisting ring and a combined loading and unloading rack with the detachable hoisting ring. This structural design makes the container bag and the hoisting device only adopt manual operation at the hoisting end, while at the unloading end Automatic unloading without manual operation. Compared with the existing operation method, it greatly improves the transfer efficiency and saves half of the manpower. It also avoids the physical and mental impact of the workers due to the harsh working environment at the unloading end. In addition, the structure of the combined loading and unloading rack is also Solved the defect that the large cargo ship cannot be loaded at one time due to the dead angle of the deck width
