Embodiment Construction

[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] The technical scheme of the present invention is mainly applied to double 40-foot container cranes, with the purpose of improving the service life of the steel wire ropes on the crane spreader and preventing the spreader from hitting the running trolley when anchored.

[0037] Referring to Figure 1 and Figure 3, the running trolley of the double-lift container crane includes:

[0038] The hoisting pulley block is installed on the base frame 9 of the trolley, and includes an inner gear pulley block 11 and an outer gear pulley block 12 . The inner gear block 11 and the outer gear block 12 avoid the reverse winding of the steel wire rope 33, greatly improving the life of the steel wire rope 33. At the same time, the positional arrangement of the inner gear block 11 and the outer gear block 12 ensures that the upper frame 8...

Abstract

The dual elevating container running cart and hanging anchor comprises the elevating pulley block composed of in and out pulley blocks, anchoring system composed of hydraulic oil cylinder, anchor rotary pin, one active end of the hydraulic oil cylinder pushing the rotation of the anchor pin, the hammer limit device composed of extending barrel and limit switch and connected to the steel wire and limit switch loosely. It can realize anchorage, relying on the anchor rotary pin bearing the hanging weight, greatly increasing the steel wire's durability, preventing oscillation and collision of anchorage with low maintenance cost and improved economical gains.

Description

technical field [0001] The invention relates to a port double 40-foot container crane, and more specifically relates to a running trolley of a double-lift container crane and an anchoring method thereof. Background technique [0002] The strong demand for world container transportation and the continuous growth of container port throughput have put forward newer and higher requirements for container handling technology and equipment. Therefore, it is urgent to develop and design a high-efficiency shoreside container handling system to meet the needs of large-scale and high-speed ships. Demands on crane productivity. Port container crane is a kind of container loading and unloading technical equipment. It generally consists of main structure, running trolley, lifting mechanism, pulley block, and spreader rack. The running trolley slides on the height of the crane. , the spreader is put on the shelf to implement the transportation of the goods. For example, for the double 40...
