Description

Metal pipe clamp assembly

Technical Field

The utility model relates to a boats and ships field specifically relates to a metal pipe clamp subassembly that is used for fixed outside pipeline of being connected with marine diesel engine.

Background

In a ship with higher requirements for controlling vibration noise, the diesel engine is arranged on a hull base and is connected by adopting an elastic support, and the external pipeline is connected with the diesel engine by adopting soft connections such as a rubber joint or a hose.

When the diesel engine works, the external pipeline connected with the diesel engine can also follow the vibration. There are two conventional ways of fixing the pipeline, the first way is to use a common U-shaped pipe clamp connection. The U-shaped pipe clamp is made of round steel, the contact surface of the U-shaped pipe clamp and a pipe is small, the strength is limited, the pipeline cannot be effectively fixed, and the vibration and the noise of the pipe cannot be avoided; meanwhile, the tail end of the U-shaped pipe clamp and the section bar are locked by the nut, after the U-shaped pipe clamp is used for a long time, the pipe clamp is subjected to continuous vibration, the nut has a falling risk, and the flexible connection of the pipeline is easy to damage. The second mode adopts that the nylon pipe clamp is connected, and the nylon pipe clamp adopts plastics preparation, and the pipe clamp is inside to be hollow intensity lower, and fixed big pipe diameter can't avoid vibrations, the noise of pipe when having the pipeline of vibrations. The nylon pipe clamp can be aged after being used for a long time, so that the pipeline is displaced, and the pipeline connection is easy to damage.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1, a metal pipe clamp assembly for fixing an external pipeline connected to a marine diesel engine may include an upper metal clamping block 1, a lower metal clamping block 2, and a bracket base 3, wherein the upper metal clamping block 1 and the lower metal clamping block 2 are welded to the bracket base 3, the bracket base 3 is welded to a steel structure of a hull through a backing plate 4, and the upper metal clamping block 1 is fixedly connected to the lower metal clamping block 2 through a bolt 5 and a washer 6 to clamp and fix the external pipeline. Preferably, the bolts 5 may be high strength bolts to ensure a reliable connection and a long service life. The washer 6 may be a spring washer.

The upper metal clamping block 1 and the lower metal clamping block 2 are basically the same in structure. Specifically, the upper metal clamping block 1 has a first semicircular groove 11 with an opening facing downward and through holes 12 located on both sides of the first semicircular groove 11, and the lower metal clamping block 2 has a second semicircular groove 21 with an opening facing upward and screw holes 22 located on both sides of the second semicircular groove 21.
