Protection belt winding device for petroleum transport pipeline

Abstract

The invention discloses a protection belt winding device for a petroleum transport pipeline. The protection belt winding device for the petroleum transport pipeline protection belt winds a protectionbelt around the outer side of the petroleum pipeline by two layers through two-way rotation. The winding layer is thick, the protection effect is better, and the efficiency is high. The protection belt winding device is characterized in that a supporting plate is placed on a fixing frame; the fixing frame is of a circular ring structure; the bottom of the supporting plate is tangent to the outer circle of the fixing frame; one end of a connection plate is connected with the supporting plate; a supporting block is placed on the connection plate; an arc-shaped bracket is placed on the supportingblock; a plurality of rubber bulges are placed on the inner side of the arc-shaped bracket; an outer fixing ring is placed on the fixing frame through a bearing; an inner gear ring is placed on the inner side of the outer fixing ring; a through hole is formed in the outer fixing ring; one end of a main screw rod penetrates through the outer fixing ring and the fixing frame in sequence, the main screw rod is in threaded fit with the outer fixing ring, and a fixing rod is placed at the other end of the main screw rod; a main winding roller is rotatably placed on the fixing rod connected with the main screw rod; limiting rings are placed on the two sides of the main winding roller correspondingly; and an inner fixing ring is placed in the inner gear ring.

Description

technical field [0001] The invention relates to a protective tape winding device for a petroleum transportation pipeline, and relates to a device for winding a protective tape on the outside of the pipeline during the laying process of the petroleum transportation pipeline. It belongs to the field of petrochemical industry. In particular, it relates to a device for wrapping the outer side of an oil pipeline with a double-layer protective tape through two-way rotation. Background technique [0002] At present, in the process of laying oil pipelines, whether it is the transfer and transportation of oil pipelines or the outer protection of oil pipelines after laying, they are the main process of construction. During the transfer and laying of oil pipelines, in order to protect The protective layer is usually wound on the outer wall of the pipeline. The protective layer has various forms, but they are all flexible materials. The protective layer is cut into rolls, and then spir...

[0002] At present, in the process of laying oil pipelines, whether it is the transfer and transportation of oil pipelines or the outer protection of oil pipelines after laying, they are the main process of construction. During the transfer and laying of oil pipelines, in order to protect The protective layer is usually wound on the outer wall of the pipeline. The protective layer has various forms, but they are all flexible materials. The protective layer is cut into rolls, and then spirally wound on the outer wall of the pipeline, so that the protective layer and the pipeline are bonded to form a protection. In the past, The winding is one-way winding, which is carried out by two workers. The outer surface of the pipeline is completely wrapped with felt cloth. The winding efficiency is low. After winding, the protective layer is thin and the protection effect is poor. The superimposed area of ​​winding is different in size, and it is necessary to adjust the speed of manual advancement, which will slow down the winding efficiency, and the tightness of winding is also determined manually. The tightness of each winding circle is different, and slack will occur during the protection process. In some cases, some existing winding equipment rotates through the pipe, so that the winding pipe is unidirectionally rotated for winding, but the pipe is large in size, the power required for rotation is high, and the pipe cannot be rotated and wound after installation, which has limitations. Sex, and the winding is one-way winding, and the difference between them is stacked and fixed, but it is easy to fall off as a whole due to the looseness of a single turn, which affects the protective effect
