Pressure increasing type automatic locating steel pipe clamp

Abstract

The invention provides a pressure increasing type automatic locating steel pipe clamp. The pressure increasing type automatic locating steel pipe clamp comprises an upper pipe clamp, a boss, a bottom plate, a hexagonal bolt and a fixing plate; according to the specific structure and connection relationship, the boss and the bottom plate are integrally welded and fixed on the fixing plate; the hexagonal bolt passes through a through hole in the upper pipe clamp to be screwed into a screw hole in the boss, thus a steel pipe can be pressed through the upper pipe clamp, and a lateral force is produced when the upper pipe clamp presses the steel pipe, and as a result, the upper pipe clamp can be prevented from being rotated during screwing the bolt. According to the pressure increasing type automatic locating steel pipe clamp, the pipe clamp can be fixed with one bolt, so that the mounting is simple and convenient; the clamping is firm; the outside diameter of the steel pipe is variable; the automatic locating and other functions can be achieved; the generality is high; the adaptability is high.

Description

technical field [0001] The invention relates to a pipe clamp for clamping a steel pipe on a working device of a hydraulic excavator, in particular to a pressurized automatic positioning steel pipe pipe clamp. Background technique [0002] There are generally several steel pipes on the boom of the hydraulic excavator, and pipe clamps are needed to fix the steel pipes. There are three kinds of pipe clamps currently used. The first one is to mill out two semicircular grooves from a cuboid steel block, and clamp the steel pipe together with the upper and lower pieces. This pipe clamp machine has many processing procedures, requires high processing precision, and high processing cost; because the outer diameter of the steel pipe and the size of the pipe clamp cannot be guaranteed to be uniform, an additional rubber pad is generally used between the steel pipe and the pipe clamp during installation, and the installation is inconvenient . The second is stamping and forming accord...

Problems solved by technology

This pipe clamp machine has many processing procedures, requires high processing precision, and high processing cost; because the outer diameter of the steel pipe and the size of the pipe clamp cannot be guaranteed to be uniform, an additional rubber pad is generally used between the steel pipe and the pipe clamp during installation, and the installation is inconvenient

The second is stamping and forming according to the diameter of the steel pipe, which requires a special mold to make it. It is also difficult to unify the outer diameter of the steel pipe and the arc size of the pipe clamp. Generally, a rubber pad is required between the steel pipe and the pipe clamp during installation.

The third type is casting pipe clamps. This type of pipe clamps is relatively large in size, thick and unsightly in appearance.
