Component clamping device in composite material pipe shaft pressure test and application method thereof

Abstract

The invention discloses a component clamping device in a composite material pipe shaft pressure test. The component clamping device comprises a flange disc, a round pipe arranged in the flange disc in a sleeved manner, and at least three cushion blocks arranged in the round pipe for overlapping the end surface center of a composite material to be tested with the top surface center of the flange disc. The application method is as follows: one end of the composite material pipe to be tested is sleeved with the clamping device; the cushion blocks are added for overlapping the end surface center of the composite material to be tested with the top surface center of the flange disc; a gap between the composite material pipe to be tested and the round pipe is filled with resin adhesive; and after the resin adhesive is fixed, the flange disc is mounted on a testing machine. The clamping device and the application method have the following advantages: the flange disc and the testing machine are butted to each other to fix the composite material pipe to be tested in the round pipe; the composite material pipe to be tested is regulated through the cushion blocks to be in the accurate position; finally, the resin adhesive is used for fixing to obtain accurate testing data. The device mainly consists of three parts, and is simply structured and conveniently produced; and the placement of the composite material pipe to be tested can meet the requirements through at least three cushion blocks.

Description

technical field [0001] The invention relates to a component clamping device in the axial compression test of a composite material tube and a using method thereof. Background technique [0002] With the rapid development of urban construction, land resources are becoming more and more scarce, and people's awareness of environmental protection is also increasing. At present, transmission lines have become very difficult in terms of policy handling, demolition and resettlement, and saving corridors. This is one of the main starting points for the State Grid Corporation of China to carry out research on composite towers in 2009. [0003] Composite material tower is a new type of tower in which the main force-bearing member or cross-arm part of the transmission tower is made of composite materials. It makes full use of the advantages of composite materials such as good insulation, high strength, light weight, corrosion resistance, easy maintenance and strong designability. Innov...
