Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a subway contact rail protective device. Background Technology

[0002] The subway contact rail, also known as the overhead contact line or suspension rail, is one of the key components of the subway power system. It is used to transmit high-voltage direct current to the train's motor. It typically consists of a continuous conductor rail and a supporting structure to ensure stable and reliable electrical contact for the train.

[0003] During the construction of subway contact rails, protective components are needed to protect their exterior. This is to prevent damage to the track and to prevent safety hazards from contact with external organisms. Traditionally, subway contact rails are protected using specialized protective covers. These covers are placed over the outside of the contact rail and secured with bolts using specialized brackets. However, due to the long length of subway contact rails, the protective covers need to be laid in sections. During installation, manual labor is required to hold the ends of the protective covers and position them on the specialized brackets before fixing them with bolts. This lack of auxiliary positioning makes installation cumbersome. Furthermore, the lack of connecting parts between adjacent protective covers results in gaps between them. Over time, this can lead to unstable connections between adjacent protective covers, affecting the protective effect on the subway contact rail. Therefore, we propose a subway contact rail protection device to solve the above problems. Utility Model Content

[0026] Example: Figure 1-6 As shown, this utility model provides a subway contact rail protection device, including a mounting bracket 1, a protective cover 2 on the top of the mounting bracket 1, the protective cover 2 protects the outside of the subway contact rail by setting the protective cover 2, a connecting piece 3 is provided between two adjacent protective covers 2, an auxiliary support frame 4 is provided on the top side of the mounting bracket 1, and a mounting bolt 11 is threaded on the top of the mounting bracket 1, the end thread of the mounting bolt 11 is threaded on the middle of the auxiliary support frame 4 for installation and fixation of the auxiliary support frame 4;

[0027] The top of the mounting bracket 1 is provided with an outer groove 101 for wire threading, and the bottom side of the protective cover 2 is provided with an inner groove 201 for wire threading corresponding to the outer groove 101. By setting the outer groove 101 and the inner groove 201, it is convenient for external wires to extend through the outer groove 101 and the inner groove 201 to the protective cover 2 and connect to the subway contact rail. The top of the auxiliary support frame 4 is provided with an auxiliary fixing groove 401 corresponding to the protective cover 2.
