Angle-adjustable supporting device and application method thereof

Abstract

The invention discloses an angle-adjustable supporting device and an application method thereof. The angle-adjustable supporting device comprises a supporting device body. The supporting device body is provided with two supporting mechanisms, wherein the supporting mechanisms are vertically and symmetrically arranged and each supporting mechanism comprises a large supporting arm and a small supporting arm penetrating the inside of the large supporting arm; the outside of each large supporting arm is connected with the supporting device body. Both ends of the small supporting arms are provided with a roller seat and a location hole respectively, and the location hole is formed on the lower portion of the corresponding large supporting arm. An operator can choose a proper shaft element to penetrate the location hole, hold one end of the shaft element and exert strength along the arc surface of the small supporting arm to enable the small supporting arm to rotate along the axis of the small supporting arm in the large supporting arm, thus further enable the relative angle between rollers to change and stop rotating the small supporting arm when a preset angle is achieved. The supporting device can adjust location of the small supporting arm through the location hole of the small supporting arm to enable the roller surface on the two supporting mechanisms to be at the same height to ensure supporting accuracy.

Description

technical field [0001] The invention relates to a support device, in particular to an angle-adjustable support device and a method for using the same, belonging to the fields of petroleum, machinery and medical treatment. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. The nature of petroleum varies with the place of origin, the density is 0.8 ~ 1.0 g / cm3, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, and is soluble in many organic solvents , Insoluble in water, but can form emulsion with water. However, the composition and appearance of oil in different oil fields can be greatly distinguished. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the contacted relative support parts caused by the traditional support device are not in the same plane, and provide a support device capable of adjusting the angle and its use method. The support device can use the positioning hole of the small support arm Adjust the position of the small support arm so that the wheel surfaces of the rollers on the two support mechanisms are at the same height to ensure support accuracy
