Description

Multifunctional pipeline jacking mechanism for hydraulic and hydroelectric engineering

Technical Field

The utility model relates to a technical field is demolishd to valve between the pipeline of perpendicular installation, specifically is a multi-functional pipeline climbing mechanism that hydraulic and hydroelectric engineering used.

Background

During the installation and maintenance of metallurgical industrial equipment, the operation tasks of pipeline replacement, connection and valve replacement among pipelines are frequently encountered, and the conventional operation method is to use hoisting equipment or tools such as a crane or a chain block and the like to disassemble section by section and then install the hoisting equipment or tools sequentially. The method has low working efficiency, high operating cost and much personnel investment, and particularly has prominent influence on production in the process of replacing the valve between pipelines.

Based on the background technology, the Chinese patent application No. CN201621234223.5 also discloses a manual quick portable pipeline jacking device, which comprises a movable bracket, an upper clamp, a lower clamp and a jacking bolt; the movable support is an upper sleeve pipe and a lower sleeve pipe, the upper sleeve pipe is fixedly connected with the upper clamp, and the lower sleeve pipe is fixedly connected with the lower clamp. A hole of 20mm is drilled in the center of a connecting plate of the upper hoop and the end of the upper sleeve, a jacking bolt of 20mm is assembled by tapping, a supporting plate is welded at the corresponding position of the end of the lower sleeve to receive jacking force, and the effect of jacking the pipeline is achieved by rotating the bolt.

However, the designer finds that the jacking mechanism of the structure can not jack the pipeline when the valve is disassembled and assembled, because the middle section of the pipeline passes through the valve installed by the flange, even if the bolt is disassembled, the pipeline with the top butted with the valve can be longer, and in the actual pipeline installation, the pipeline can be fixed on a building structure through the fixing mechanism, the same way as that in the patent cannot be realized, the whole pipeline disassembled from the valve can be jacked by only jacking the pipeline upwards through the bolt, and even if the jacking action can be completed, when the top clamping ring mechanism is jacked by binding the pipeline, the clamping ring mechanism can also be distorted and deformed due to the weight of the pipeline, so the jacking structure design of the patent belongs to an ideal state.
