Description

Technical Field

[0001] The invention relates to the technical field of pipeline clamping and fixing devices, and in particular to a pipe clamp using a T-bolt matched with a support rail. Background Art

[0002] In the design of the braking system pipeline of urban rail transit vehicles, pipe clamps play a vital role. Their main function is to tighten the air supply pipeline, so as to effectively prevent the air supply pipeline from vibrating due to various forces during the operation of the vehicle. This is of key significance to ensure the stable operation of the braking system and the safe driving of the entire vehicle.

[0003] For stainless steel vehicles, the pipe clamps are usually fixed with hexagonal bolts and nuts. This method is common and applicable in the structural system of stainless steel vehicles, by connecting and fixing the pipe clamps to the holes in the vehicle body or the pipe mounting seat. However, the body frame of aluminum alloy vehicles is different. The body frame of aluminum alloy vehicles is generally an aluminum alloy profile structure with a slide groove. In this structure, there are no holes specifically for bolt connection, which makes the traditional hexagonal bolt and nut fixing method unable to be directly applied to aluminum alloy vehicles. Summary of the invention

[0004] According to the technical problem that the pipe clamp cannot be fixed by the hexagonal bolt and nut fixing method due to the body chassis structure of the aluminum alloy vehicle, a pipe clamp using a T-bolt and a support rail is provided. The present invention uses the form of opening semicircular holes in the upper pipe clamp body and the lower pipe clamp body to clamp and fix the hard pipe. The upper and lower pipe clamp bodies are both provided with bolt holes, and the pipe clamp bodies are connected and clamped by T-bolts, nuts, flat washers, and spring washers. The T-bolt can be placed in the support rail through the slide groove position without sliding in from the side, and the installation and removal are easy to operate. A V-groove is set at the tail of the bolt parallel to the long side of the bolt head to check whether the bolt is installed in place. The diagonal rounded corners of the bolt head facilitate the rotation of the bolt in the support rail. A square boss is set at the connection between the bolt head and the thread. The boss can be stuck in the slide groove flange during hoisting installation to ensure that the pipeline does not rotate during the adjustment process.

[0005] The technical means adopted by the present invention are as follows:

[0006] A pipe clamp using a T-bolt and a support rail, comprising: an upper pipe clamp body and a lower pipe clamp body;

[0007] The upper tube clamp body and the lower tube clamp body each have a semicircular hole for clamping and fixing the hard tube, and the upper and lower tube clamp bodies are both provided with bolt holes, and the tube clamp bodies are connected and clamped by T-bolts, nuts, flat washers, and spring washers;

[0008] The T-bolt is placed in the support rail through the slide groove, a V-groove is arranged at the tail of the bolt and is parallel to the long side of the bolt head, the corners of the bolt head are rounded diagonally, and a square boss is arranged at the connection between the bolt head and the thread.

[0009] Furthermore, a cover plate is provided on the upper side of the upper tube clamp body and is fixed to the upper side of the upper tube clamp body by T-bolts.

[0010] Furthermore, the T-bolt is placed in the support rail through the slide slot and rotated 90 degrees before being placed, and then the lower block of the pipe clamp body, the pipeline, the upper block of the pipe clamp body and the washer nut are placed in sequence.

[0011] Furthermore, the T-bolt can be checked through its V-groove to see whether the bolt is installed in place.

[0012] Furthermore, the square boss on the head of the T-bolt can ensure that the pipeline does not rotate during the adjustment process when it is hoisted and installed.

[0013] Furthermore, the pipe clamp is installed by bolts and nuts in combination with flat washers and spring washers.

[0014] Furthermore, the upper tube clamp body and the lower tube clamp body are made of PA66 nylon, and the T-bolt is made of 304 stainless steel.

[0015] Furthermore, the pipe clamp adopts a solution of pre-assembly under the vehicle.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention provides a pipe clamp that uses a T-bolt and a support rail. The T-bolt can be directly placed in the support rail through a slide groove without sliding in from the side, which simplifies the installation and removal operation process, reduces the operation difficulty and time cost, and improves the installation efficiency. Whether it is assembling a new car or replacing the pipe clamp in the later maintenance, it can bring great convenience to the staff.

[0018] 2. The present invention provides a pipe clamp that uses a T-bolt and a support rail. The pipe clamp is suitable for under-vehicle pre-assembly solutions. This method greatly improves assembly efficiency and is particularly suitable for large-scale production or scenarios that require rapid assembly. It reduces the vehicle's stay time on the assembly line and improves production efficiency.

[0019] 3. The present invention provides a pipe clamp that uses a T-bolt and a support rail, which eliminates the design of an elastic ring and avoids the difficulty in adjusting the position of the pipe clamp due to the limitation of the elastic ring. During actual installation and use, the user can more flexibly adjust the position of the pipe clamp according to the actual layout and needs of the pipeline, thereby ensuring the accuracy and rationality of the pipeline installation, while also reducing the risk of problems such as pipeline stress concentration caused by improper position of the pipe clamp.

[0020] 4. The present invention provides a pipe clamp that uses a T-bolt and a support rail. The V-groove at the tail of the T-bolt is parallel to the long side of the bolt head, which provides an intuitive way for workers to check whether the bolt is installed in place. During the installation process, the installation status of the bolt in the support rail can be judged by simply observing the position of the V-groove without the need for other complex tools or equipment. This not only improves the accuracy and reliability of the installation, but also can promptly discover possible problems during the installation process, avoiding safety hazards and subsequent failures caused by improper bolt installation.

[0021] 5. The present invention provides a pipe clamp that uses a T-bolt and a support rail. A square boss is arranged at the connection between the head of the T-bolt and the thread. When the pipe clamp is installed by hoisting, it can effectively ensure that the pipeline does not rotate during the adjustment process, avoid problems such as loose connection and poor sealing due to rotation of the pipeline, improve the stability and reliability of the pipeline installation, and thus ensure the normal operation of the air supply pipeline of the brake system, providing strong support for the safe driving of urban rail transit vehicles.

[0022] Based on the above reasons, the present invention can be widely promoted in the technical field of pipeline clamping and fixing devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values.
