Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Referring to Fig. 3, the goods referred to in this embodiment are containers. Crane comprises dolly 3 and carload 11, and dolly 3 can run back and forth (left and right) on the crossbeam of carload 11, and carload 11 can walk left and right direction (from inside to outside or from outside to inside in the figure). A spreader 1 is provided under the trolley for lifting the container 2 . The spreader 1 is driven by the power unit of the trolley, such as a winch (not shown), so that the spreader 1 including the suspended container 2 can be lifted up and down. Containers are piled up on the yard, wherein, container 5 is the container above the yard and is positioned at the front (to the left) of the dolly 3 walking passages, and container 6 is the container at the rear (to the right) of the dolly 3 walking passages above the yard.

Abstract

A high-safety controller for hoister is composed of the first height detector for measuring the top height Hq of goods stack, the second height detector for measuring the height Hd or Hi of the bottom of hoisting tool or the hoisted goods, and a central control unit connected to said two detector for controlling the running of the hoister's carriage. When Hd or Hj is not greater than Hq, the carriage is controlled to run in deceleration mode, so not colliding with goods.

Description

technical field [0001] The invention relates to a safety control device, in particular to a crane operation safety control device. Background technique [0002] With the development of port cargo transportation, especially container transportation, the port, storage yard and other cargo such as container distribution centers continue to grow, the volume of storage yard operations continues to increase, and the safety of cargo crane operations has become increasingly prominent. How to ensure the safety of cargo storage yard operations It is a problem that the transportation department must solve. The existing goods are hoisted using tire cranes (also known as field bridges) to load and unload containers using spreaders. The spreaders lift the goods, lift or descend in the vertical direction, and move forward with the trolley in the horizontal direction. Or run backwards, and the whole machine can run left and right with the cart. In this way, the goods can be hoisted from t...
