Rail cart and use method of rail cart in construction of large-diameter steel penstock

Abstract

The invention provides a rail cart and a use method of the rail cart in the construction of a large-diameter steel penstock. The rail cart comprises a cart body consisting of a framework and at least four wheels which are symmetrically arranged on two sides of the cart body, wherein flanges which can be clamped on the inner side of rails are arranged on the wheels; a supporting plate for putting the large-diameter steel penstock is arranged at each of two ends of the cart body. Before the rail cart is used, firstly, temporary rails are arranged on two sides of a pipeline buttress along the design trend of the steel penstock; secondly, the rail cart is arranged on the rails and is connected with a winch, the steel penstock is arranged on the rail cart, and the winch is started for drawing the rail cart along the rails to move to be in place; the steel penstock is arranged from a high position to a low position; after mounting is finished, the winch is started for reeling off a steel wire rope, and the rail cart returns to a pipeline hoisting point along the rails under the action of gravity. According to a mounting method for the pipeline by using the rail cart under the condition that a hoisting machine cannot completely cover the pipeline, the operation amount of workers can be greatly reduced, and construction period is shortened.

Description

technical field [0001] The invention relates to the field of pipeline installation tooling, in particular to a rail trolley for installing large-diameter pressure steel pipes and a method for using the same in the construction of large-diameter pressure steel pipes. Background technique [0002] With the development of industry, there are more and more large-scale gas and liquid transportation projects. During the construction of the pipeline, it is often necessary to transport and install large-diameter penstocks. When installing large-diameter penstocks in the prior art, usually Use hoisting machinery for auxiliary lifting. In some special occasions such as high and steep mountainous areas, there is no entry condition for large-scale hoisting equipment. If hoisting equipment is used to install penstocks, construction roads must be built, which will increase construction costs and cannot effectively guarantee the construction period. Especially when installing penstocks in...
