Heavy pipeline hoisting mechanism for highway engineering construction

Abstract

The invention discloses a heavy pipeline hoisting mechanism for highway engineering construction. The heavy pipeline hoisting mechanism comprises a hoisting vehicle, a first hoisting device, a second hoisting device, an inverted-U-shaped electromagnetic fastening assembly, a bilateral one-way fastening chain and an expansion type chain expander. The first hoisting device is arranged on the hoisting vehicle, the second hoisting device is arranged on the hoisting vehicle, the first hoisting device and the second hoisting device are arranged side by side, the inverted-U-shaped electromagnetic fastening assembly is movably arranged on the first hoisting device, the bilateral one-way fastening chain is movably arranged on the second hoisting device, and the inverted-U-shaped electromagnetic fastening assembly is movably arranged on the second hoisting device. And the expansion type chain expander is movably arranged on the bilateral one-way fastening chain. The invention belongs to the technical field of heavy pipeline hoisting equipment for highway engineering construction, and particularly relates to a heavy pipeline hoisting mechanism for highway engineering construction, which can easily clamp and release pipelines, can support the pipelines, is not easy to bend the pipelines and is convenient to align the pipelines.

Description

technical field [0001] The invention relates to the technical field of heavy-duty pipeline hoisting equipment for highway engineering construction, in particular to a heavy-duty pipeline hoisting mechanism for highway engineering construction. Background technique [0002] In the process of highway engineering construction, the laying of pipelines is an indispensable part. In the process of hoisting and construction of heavy-duty pipelines, due to the large mass and inertia of heavy-duty pipelines, it is very laborious to manually handle and align the pipelines. , causing the overall construction progress to be affected, so it is necessary to use special pipeline equipment to transport it. [0003] As a relatively common heavy-duty pipeline hoisting rope equipment in highway engineering construction, it is favored by the majority of construction units because of its high power, easy to move and not affected by the actual construction site. However, the current heavy-duty pip...

[0002] During the construction process of highway engineering, the laying of pipelines is an indispensable part. During the hoisting construction of heavy pipelines, due to the large mass and inertia of heavy pipelines, it is very laborious to manually carry and align the pipelines. , causing the overall construction progress to be affected, so it is necessary to use special pipeline equipment to carry it

[0003] As a relatively common heavy-duty pipeline hoisting rope equipment, the heavy-duty pipeline hoisting mechanism for highway engineering construction is favored by the majority of construction units because of its high power, easy movement, and unaffected by the actual construction site. However, the current heavy-duty pipeline hoisting In order to prevent the pipe from slipping during hoisting, the binding position needs to be adjusted continuously when binding the pipe. For long pipes, the hoisting point is located in the middle during hoisting, and the two ends of the pipe will be damaged by themselves. Gravity bends downward, which affects the strength of the pipeline. After the hoisting is completed, the fixing belt needs to be dismantled manually. During the whole process, workers need to constantly adjust the fixing belt. The operation is complicated and very dangerous; Both ends of the pipe are bent downwards, and the mouth of the pipe cannot be kept horizontal, which increases the difficulty of docking
