Description

Technical Field

[0001] This utility model relates to the field of railway turnout technology, specifically a fixing device for a turnout heating system. Background Technology

[0002] A railway switch is a track connection device used to allow locomotives and rolling stock to switch from one track to another. It consists of a switch, frog, guard rails, and connecting parts. The switch guides trains in different directions, while the frog ensures the wheels pass smoothly through the intersection of the two rails. Railway switches are crucial for railway transportation, enabling train scheduling, marshalling, and switching between different tracks within stations. This greatly improves the flexibility and utilization of railway lines, allowing numerous trains to operate in an orderly manner and ensuring efficient and safe railway transportation.

[0003] In cold weather, the movable parts of the turnout are prone to freezing. Heating systems can prevent and reduce train derailment, improving safety. They can also avoid delays caused by manual snow removal and protect equipment. However, heating strips in general heating systems are installed inside the stock rail or directly fixed with bolts, which can cause the connecting sleeve to wobble and damage to the connection point between the sleeve and the heating strip, leading to the loss of the heating strip's function. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fixing device for a turnout heating system, including a rail. A connecting sleeve is provided above the bottom end face of the rail. A connecting pipe is installed at one end of the connecting sleeve, and a heating strip is fixedly connected to the other end of the connecting sleeve. The heating strip is fixedly connected to the rail by a fixing clamp. The fixing clamp includes a fixing hook and a limiting hook fixedly connected thereto. The fixing hook is engaged with the connecting sleeve, and the limiting hook is engaged with the bottom end face of the rail.

[0005] The above technical solution, by setting fixed hooks and limiting hooks, facilitates the installation of heating strips of the heating system on the outside of the main rail. First, the inner wall of the fixed hook is snapped onto the surface of the connecting sleeve; then the limiting hook is placed below the rail, and the hooking position of the limiting hook is simultaneously snapped onto the bottom end face of the rail. The snapping position is on the side of the bottom end face of the rail away from the connecting sleeve, which facilitates the fixing of the heating system pipes of the turnout to the connecting sleeve, and avoids the connecting sleeve from shifting after installation, which would prevent the turnout from being stably heated.

[0006] As a further improvement to the above solution, the shape of the fixed hook is adapted to the connecting sleeve; the shape of the limiting hook is adapted to the bottom surface of the rail.

[0007] As a further improvement to the above solution, the fixing fixture is manufactured using a one-piece molding process.

[0008] As a further improvement to the above solution, the inner wall of the fixing clamp is in close contact with the bottom surface of the rail.

[0009] Through the above technical solution, the inner wall of the fixing clamp is in close contact with the bottom surface of the rail, which helps the fixing hook and the limiting hook to fit the rail better, increases the firmness of the fixing clamp, and thus ensures the stability of the connecting sleeve on the rail, thereby ensuring the stability of the entire heating system on the switch and preventing shaking or displacement during use.

[0010] As a further improvement to the above solution, a base is fixedly connected to the bottom of the rail, and a bolt is provided at one end of the base near the connecting sleeve. A retaining plate is fitted onto the surface of the bolt, and a nut is threaded onto the surface of the bolt.

[0011] With the above technical solution, the bolt is located on the surface of the base near the end of the connecting sleeve. This setting facilitates the fixing and positioning of the connecting pipe by means of bolts, clamps and nuts, making the installation of the connecting sleeve on the rail more stable, and also helps to better integrate the connecting sleeve with other components around the rail, ensuring the compact structure of the entire heating system.

[0012] As a further improvement to the above solution, the surface of the nut is in contact with the clamping platform, and the connecting tube passes through the front and rear ends of the clamping platform.

[0013] Through the above technical solution, the surface of the nut contacts the clamping platform, which ensures the limiting effect of the nut on the clamping platform and prevents the clamping platform from sliding freely on the bolt; the connecting tube runs through the front and rear ends of the clamping platform, which helps to position and fix the connecting tube, ensuring the stability of the position of the connecting tube, thereby ensuring the normal operation of the heating system and preventing the connecting tube from shaking or shifting and affecting the heating efficiency.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting a fixed hook and a limiting hook, facilitates the installation of the heating strip of the heating system on the outside of the main rail. The connecting pipe passes through the inside of the clamping platform, and the connecting sleeve is fixed above the bottom end face of the rail, so that the inner wall of the fixed hook is engaged with the surface of the connecting sleeve. The limiting hook is placed below the rail, and the hooking position of the limiting hook is simultaneously engaged with the bottom end face of the rail. The engagement position is on the side of the bottom end face of the rail away from the connecting sleeve, which facilitates the fixing of the heating system pipe of the turnout to the connecting sleeve and avoids the connecting sleeve from shifting after installation, which would prevent the turnout from being stably heated.
