Problems solved by technology

There are following disadvantages in using this method for measurement: first, the measurement accuracy is low, and the crane is unstable after the steel chain is applied, causing the data of the sensor to change all the time, and the range of change is large, resulting in inaccurate measurement structure; There is no joint installed at the time, and the hose transmits force through the joint. If the joint is not consid

Abstract

The invention relates to a device for measuring flexural rigidity and torsional rigidity of a hose. The device comprises a main support, a fixing shaft support saddle, a fixing shaft, two rotating shaft support saddles, a rotating shaft, a first ear plate, a second ear plate, a first oil cylinder, a movable support saddle, a second oil cylinder, a third ear plate, a fourth ear plate, a third oil cylinder, a rotary crank shaft, two fourth oil cylinders, a first lifting handle, a first rack wheel, a crank shaft and a second lifting handle. According to the device, the oil cylinder for moving the fixing shaft support saddle to facilitate the mounting of the house, the oil cylinder for forcing the hose to vertically bend and the oil cylinders for driving the rotary crank shaft to rotate to enable the hose to be torsional are sequentially arranged, and a function of simultaneously measuring the flexural rigidity and the torsional rigidity of the hose is realized; the device is simple in principle and convenient to operate, and has higher engineering practicality.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for bending stiffness and torsional stiffness of a hose. Background technique [0002] With the development of hose technology, more and more oilfield development projects use hoses. Before the hose is applied, its performance needs to be known to provide a more reliable basis for its use. The cross-sectional characteristics of the hose are a basic parameter of the hose, and the stiffness is the basis of the physical properties of the section and a key parameter in the analysis of pipeline applications. However, for the hose with complex structure, the theory cannot get accurate data of stiffness. [0003] The hose is composed of metal and non-metal materials. The typical hose structure includes a skeleton layer, an internal pressure sealing layer, a compression armor layer, a tensile armor layer and an outer cladding layer. Between each layer is The load is transmitted ...
