Description

Technical Field

[0001] The utility model belongs to the technical field of wear-resistant composite pipelines, and in particular relates to a novel wear-resistant composite pipeline structure. Background Art

[0002] Wear-resistant ceramic composite pipe is one of the most widely used wear-resistant pipes in the world. It uses high-aluminum ceramic as the inner lining layer, and the base pipe uses the metal material after sandblasting and rust removal. It is combined with the metal base pipe by gluing, and the high-aluminum ceramic is used as the working surface. It has excellent wear resistance, corrosion resistance and heat resistance. High-aluminum ceramic wear-resistant composite pipe is widely used in material conveying pipelines in power, metallurgy, mining, coal, chemical industry and other industries. It is an ideal wear-resistant pipeline and has achieved great social and economic benefits.

[0003] At present, the existing wear-resistant composite pipes are mostly installed by splicing two pipes together through flanges and bolts. During long-term use, certain vibrations will occur during the pipeline transportation of materials, which will cause the bolts to loosen and affect the transportation of materials. For this reason, we propose a new type of wear-resistant composite pipe structure. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By using the driving screw to drive the threaded sleeve to extend outward, the pressure plate is pushed to extend to the inside of the pressure groove and tightly squeezed, so that the two annular convex edges are closely spliced, and then the positioning column and the positioning hole are used to position the telescopic column. Under the action of the limit groove and the limit block, the spring sleeve and the screw are limited to avoid the screw rotating during use, thereby preventing the connection from loosening.

[0013] 2. By setting a reset spring inside the spring sleeve and cooperating with the telescopic column, the function of driving the knob to reset is realized. After the knob is rotated tightly, the telescopic column is pulled to contract under the action of the reset spring, thereby driving the knob and the positioning column to reset. The positioning column is inserted into the positioning hole to realize the positioning function and ensure its stability. BRIEF DESCRIPTION OF THE DRAWINGS
