Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline transportation, in particular to a pipeline reverse transportation roller device. Background Art
[0002] When installing pipelines in the pipe gallery, the pipeline materials must first be transported to the pipe brackets in the pipe gallery. Due to the limited space in the pipe gallery, and the design of the drawing is a column-enclosed bracket (such as Figure 1 ), and due to the spacing between the brackets, the pipe cannot be moved parallel to the bracket.
[0003] In the prior art, when encountering a large diameter pipeline, one method is to use a hand chain hoist to lift the pipeline and gradually transport it backwards and forwards. The use of a hand chain hoist has the disadvantages of large limitations, labor consumption, and potential safety hazards.
[0004] Another method is to weld the brackets from low to high layers while lifting the pipes and placing them on the brackets. However, sometimes the arrival of pipe materials lags behind the completion of bracket welding, so the pipe needs to cross multiple closed brackets from one feed port. For large-diameter pipes, the number of construction workers must be determined by considering factors such as pipe diameter, weight, length, and whether it is a finished insulated pipe. Several people are needed to pass between brackets to reach the required position smoothly. Disadvantages of this method: increased personnel costs, increased safety risks of operations, hard friction between the bracket and the pipe, which may damage the protective layer of the pipe, etc. Utility Model Content
