Description

Technical Field

[0001] This utility model relates to the field of subway engineering technology, specifically a special track fastener. Background Technology

[0002] With the development of my country's transportation infrastructure, rail transit construction has become increasingly prominent, and subways have gradually become an indispensable daily mode of transportation for people's lives, work, and commutes. While riding the subway, people have also experienced its speed, comfort, and safety, thus it is increasingly being adopted by major international cities. Especially in recent years, with the continuous construction of rail transit networks, transfer stations have become particularly important. During the underpass construction process, information-based monitoring of the impact on existing lines during construction is crucial, and specially designed fasteners are used to monitor track lateral elevation differences and track spacing. However, the existing custom-made fasteners still have the following technical problems when used: Existing fasteners have complex structures, making them inconvenient to install and resulting in poor stability after installation, thus limiting their widespread use in construction.

[0003] Therefore, a specially designed track fastener is proposed to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a special track fastener to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special track fastener, including a mounting buckle, wherein the side wall of the mounting buckle is provided with a threaded hole, a threaded rod is longitudinally provided through the inside of the threaded hole, the lower end of the threaded rod is integrally formed with a bent part, a washer is sleeved on the upper end of the threaded rod, and a fastening nut is threadedly connected to the upper end of the washer.

[0006] Preferably, the mounting fastener includes a first fastening part and a second fastening part, and the inner walls of both the first fastening part and the second fastening part are fixed with a rubber anti-slip layer.

[0007] Preferably, the bending angle of the bent portion is 45-60 degrees.

[0008] Preferably, the diameter of the threaded rod is 10 mm, and the diameter of the threaded hole is 14 mm.

[0009] Preferably, the thickness of the mounting clip is 3mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This application has a simple structure. The mounting clips are made of 3mm thick steel plates, which provide a stable and secure fit during later fixing. After installation, it ensures a firm fit without affecting train traffic. It can also provide feedback on track bed settlement. The fasteners are easy to install without damaging the rails, have high stability, and will not fall off or slide due to their own reasons. They are reusable and can be used for normal track monitoring at any time. They can be widely used in subway construction. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0015] Please see Figure 1-2 This utility model provides a technical solution: A special track fastener includes a mounting clip 1. The mounting clip 1 has a threaded hole on its side wall. The threaded rod 2 has a diameter of 10 mm and the threaded hole has a diameter of 14 mm. The threaded rod 2 is longitudinally inserted through the threaded hole. The lower end of the threaded rod 2 has an integrally formed bent portion 3. The threaded rod 2 and the bent portion 3 are integrally formed by stamping and forging. The bending angle of the bent portion 3 is 45-60 degrees. A washer 4 is sleeved on the upper end of the threaded rod 2. A fastening nut 5 is threadedly connected to the upper end of the washer 4.

[0016] The mounting fastener 1 includes a first fastening part 6 and a second fastening part 7. The thickness of the mounting fastener 1 is 3mm. The inner walls of the first fastening part 6 and the second fastening part 7 are both fixed with a rubber anti-slip layer. By setting the rubber anti-slip layer, the anti-slip effect of the mounting fastener 1 when in contact with the guide rail is increased, thereby increasing stability.

[0017] Working principle: The threaded rod 2 in this application is made of φ14 round steel, and the bent part 3 at one end is bent at 45-60 degrees. The mounting buckle 1 is reinforced with 3mm thick steel plate to form a U-shaped groove. 14mm bolt holes are drilled in the steel plate. The rail clamping device is installed on the bottom of the rail on site, and the small prism is installed on the side of the U-shaped groove and fixed with bolts. After installation, it is ensured to be firm and not affect the passage of trains. The track can be monitored normally at any time.
