Problems solved by technology

[0005] The object of the present invention is to provide an offshore platform crane with trolley luffing, which solves the problem of the extra drive power consumption caused by the lifting of the center of gravity when hoisting with a small tonnage in the prior art, the luffing track is an arc, and the luffing speed is not high. Uniform; there are many luffing ropes, resulting in low luffing efficiency

Abstract

The invention discloses an ocean platform crane with a buggy luffing mechanism. A main lifting mechanism, an auxiliary lifting mechanism and a buggy luffing mechanism are arranged in a lifting arm, the main lifting mechanism is in transmission connection with a main lifting hook, and the auxiliary lifting mechanism is in transmission connection with an auxiliary lifting hook in the buggy luffing mechanism; the buggy luffing mechanism is structurally characterized by comprising a moving buggy arranged on a slide rail of the lifting arm, the auxiliary lifting hook is installed on the moving buggy downwards, the two sides of the moving buggy are respectively connected with traction cable wires, and the traction cable wires are in sequential transmission connection with an auxiliary luffing winch through a plurality of guide pulleys. The device provided by the invention is provided with a movable arm luffing mechanism and the buggy luffing mechanism to fully play the advantages of the two luffing modes and especially reduce the driving power and improve the working efficiency in the frequently used small tonnage lifting process.

Description

technical field [0001] The invention belongs to the technical field of offshore platform lifting equipment, and relates to an offshore platform crane with trolley luffing. Background technique [0002] The offshore platform crane is a special lifting device installed on the deck of the offshore platform. It is widely used in various offshore platforms and is an important component of the offshore platform. On the platform, offshore platform cranes frequently lift equipment and transport staff up and down the platform every day, and their utilization rate is relatively high. However, in terms of lifting weight, they are mainly concentrated in small tonnages, and the number of liftings in large tonnages is seldom. [0003] Existing offshore platform cranes only use one luffing method: boom luffing. Boom luffing is realized by rotating the boom in the vertical plane to change the elevation angle of the boom. There are two types, one is wire rope luffing jib, the other is hydra...
