Quay crane

Abstract

The invention discloses a quay crane. The quay crane comprises a cart, a lifting appliance, a conveying device and a guiding and positioning device, wherein a guide rail is arranged on the ground, thecart is arranged on the guide rail and horizontally moves along the guide rail, the lifting appliance used for carrying containers is arranged on the cart, the conveying device conveys the containers, and the guiding and positioning device is used for guiding the containers to be placed on the conveying device. According to the quay crane of the invention, the lifting appliance is matched with the conveying device, so that the use of a truck is replaced, full-automatic carrying is realized, and the environmental pollution is reduced; and in addition, the guiding and positioning device is arranged, so that the containers can be quickly positioned in the unloading process, and the ship unloading efficiency is improved. Meanwhile, the quay crane of the invention reduces the working intensityof the driver and reduces the dependence on the professional operation of the driver. The invention adopts a hydraulic cylinder to match with a connecting rod to adjust the position of a movable bracket, thereby reducing the equipment cost and the maintenance cost of the later equipment while ensuring the driving force.

Description

technical field [0001] The invention relates to the field of port lifting, in particular to a container loading and unloading device for a quay bridge. Background technique [0002] Shipping by sea is by placing the goods in the container and transporting them to the port by ship. Generally, when the ship is unloaded by the shore bridge, the container on the ship is hoisted to the truck by the spreader and then transported to the back yard, and then the container is lifted from the truck by the spreader. remove. When loading the ship, the container is placed on the truck by the spreader, and the container is transported to the bottom of the quay bridge by the truck, and transported to the ship by the trolley. The work intensity is high and the work efficiency is low. In addition, when the spreader is placed on the truck, since the spreader is usually hoisted by cables, it cannot be guaranteed to reach the designated position after moving, and the container may be deflected...

AI Technical Summary

Problems solved by technology

High work intensity and low work efficiency

In addition, when the spreader is placed on the truck, since the spreader is usually hoisted by cables, it cannot be guaranteed to reach the designated position after moving, and the container may be deflected, causing the container to overturn, or even more serious safety accidents

Transported by container trucks, the labor cost is high, and there is a certain degree of environmental pollution
