Structural pipe hoisting device for ocean engineering

Abstract

The invention discloses a structural pipe hoisting device for ocean engineering, and relates to the technical field of pipe hoisting devices, the structural pipe hoisting device comprises a tower crane cantilever, the bottom of the tower crane cantilever is provided with a driving part used for hoisting a structural pipe, the driving part is provided with three winding drums, the three winding drums are arranged in parallel, and the winding drums are connected with the tower crane cantilever. The three winding drums are each provided with two safety cables, the bottom ends of the six safety cables are provided with three automatic pipe fitting clamping parts used for stably clamping pipe fittings, and the safety cables are provided with rope mounting parts used for conveniently disassembling the safety cables. When clamping is needed, the hanging process is stable and reliable, meanwhile, adjustment can be conducted according to the specification and the number of pipe fittings, the safety cable can reduce shaking generated by transferring when the pipe fittings are hung in the air to the maximum extent, and the probability of pipe fitting damage and safety accidents caused by falling of the pipe fittings is reduced; and the safety of the structural pipe hoisting device for ocean engineering is improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting hoisting devices, in particular to a structural pipe hoisting device for marine engineering. Background technique [0002] Marine engineering refers to the new construction, reconstruction and expansion projects aimed at the development, utilization, protection and restoration of marine resources, and the main body of the project is located on the seaward side of the coastline. It is generally divided into two parts: resource development technology and equipment and facility technology. A large number of structural pipes are commonly used in engineering to build infrastructure. Structural pipes generally refer to structural steel pipes, which are divided into hot-rolled seamless steel pipes and welded steel pipes. During the construction of marine engineering, lifting devices are often used to transfer and transport structural pipe fittings. [0003] The existing pipe fittings hoisting device...

AI Technical Summary

Problems solved by technology

[0003] The existing pipe fittings hoisting device generally uses a crane to hang the hook on the binding rope of the structural pipe for transfer. However, this hoisting method will cause the structural pipe and the cantilever of the pendant tower to be stressed at a single point, resulting in the structural pipe. The overall stress on the cantilever of the pendant tower is uneven, and there is a lack of insurance measures. It is easy to cause the pipe fittings to break away or the connection between the suspension rope and the cantilever of the pendant tower to break, resulting in damage to the pipe fittings and safety accidents. Therefore, in order to solve the above problems, this application proposes a marine engineering Lifting device with structural pipe
