[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0034] An embodiment of the present application provides a tube clamp structure for an EMU, in which a spring sheet is placed in a tube clamp seat, and the clamping force of an external bolt is utilized so that the tube clamp seat applies the clamping force to the outer surface of the tube through the deformation of the spring sheet, thereby achieving uniform force and effectively ensuring elastic stability.

[0035] To achieve the above technical effects, the overall idea of this application is as follows:

[0036] A pipe clamp structure for an EMU, comprising:

[0037] A pipe clamp 1 of an annular plate structure or an arc-shaped plate structure, wherein threaded holes 10 are provided at both ends of the pipe clamp 1;

[0038] A spring sheet 2 provided on the inner side of the pipe clamp 1;

[0039] The pipe clamp 1 is provided with flange structures 11 on both sides for limiting the spring sheet 2;

[0040] The spring sheet 2 is a sinusoidal spring sheet.

[0041] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0042] See also Figures 1 to 10 As shown, an embodiment of the present application provides a train set pipe clamp structure, the train set pipe clamp structure comprising:

[0043] A pipe clamp 1 of an annular plate structure or an arc-shaped plate structure, wherein threaded holes 10 are provided at both ends of the pipe clamp 1;

[0044] A spring sheet 2 provided on the inner side of the pipe clamp 1;

[0045] The pipe clamp 1 is provided with flange structures 11 on both sides for limiting the spring sheet 2;

[0046] The spring sheet 2 is a sinusoidal spring sheet.

[0047] It should be noted that the inner and outer diameters and deformation of the spring sheet 2, as well as the diameter of the external pipe clamp 1, are determined according to the diameter of the fixed pipe. The height of the folds on both sides of the pipe clamp 1 is also determined according to the deformation of the spring sheet 2, so as to prevent dirt from entering the spring sheet 2 to the greatest extent.

[0048] In the embodiment of the present application, a spring sheet is placed in the pipe clamp, and the compression force of the external bolt is utilized so that the pipe clamp applies the compression force to the outer surface of the pipe through the deformation of the spring sheet, thereby achieving uniform force and effectively ensuring elastic stability.

[0049] Furthermore, the height of the spring piece 2 ranges from 3 mm to 5 mm.

[0050] Furthermore, the pipe clamp 1 is an annular plate structure, and end plates 12 are respectively provided at both ends of the pipe clamp 1;

[0051] The threaded hole 10 is provided on the end plate 12;

[0052] The two threaded holes 10 are arranged opposite to each other.

[0053] Furthermore, the pipe clamp 1 is an arc-shaped plate structure, and end plates 12 are respectively provided at both ends of the pipe clamp 1;

[0054] The threaded hole 10 is provided on the end plate 12 .

[0055] The technical solution based on the embodiment of this application has the following technical details during specific implementation:

[0056] The EMU pipe clamp structure is mainly composed of two parts, namely the pipe clamp seat 1 and the spring sheet 2;

[0057] The spring sheet 2 is installed inside the pipe clamp 1 and is pressed against the interface component of the vehicle body through the threaded hole of the pipe clamp 1 by means of bolt fasteners;

[0058] As the threaded fastener is tightened, the pipe clamp 1 contracts and deforms inwards, and the pressure acts on the internal spring sheet 2, which deforms and presses the pipe;

[0059] Relying on the above structure, the stability can be maintained for a long time. As the running time increases, the elastic force of the spring piece 2 will change slightly, but the change affected by the environment such as temperature and humidity is smaller than that of rubber material.

[0060] In the technical solution of the embodiment of the present application, the pipe clamp 1 is primarily composed of stainless steel plate, processed into a standard pipe clamp structure and having inwardly facing flanges on both sides. This prevents the spring leaf 2 from falling out of the pipe clamp 1 due to deformation during tightening or vibration during operation. It also effectively prevents dirt from entering the spring leaf 2 and affecting its elasticity. The smooth interior surface of the pipe clamp 1 ensures that the spring leaf 2 can deform freely and unimpeded during the compression process.

[0061] The pipe clamp seat 1 is divided into a single-hole pipe clamp and a double-hole pipe clamp. The single-hole pipe clamp has one fixing point, and the double-hole pipe clamp has two fixing points. The fixing points can be threaded holes 10.

[0062] In the technical solution of the embodiment of the present application, the main material of the spring piece 2 is spring steel, which is processed into a sine wave shape and has a height of 3-5 mm, which can be adjusted according to the actual diameter of the pipe clamp;

[0063] The spring piece 2 is an independently processed component and is installed by being placed inside the pipe holder 1;

[0064] When the spring sheet 2 is installed, under the compression force of the pipe clamp 1, the spring sheet 2 can be deformed freely and still maintain the deformation force after the bolt is tightened.
