[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution for a subway communication equipment signal base station fixing device:

[0021] A signal base station fixing device for subway communication equipment includes a mounting frame 3, which is fixed to a tunnel segment 2 by expansion bolts. The mounting frame 3 is used to install a signal base station 1, and the signal base station 1 is slidably arranged on the mounting frame 3. The mounting frame 3 is composed of two mutually parallel arc tracks 4 and a connecting plate 5 for connecting the two arc tracks 4. The arc track 4 is fitted with the tunnel segment 2. The arc track 4 is composed of a bottom plate and two side plates 6. The side plates 6 are provided with a sliding groove 7 that passes through left and right along the length direction thereof. Two sliding blocks 1 are arranged in the sliding groove 7. 0, each of the sliding blocks 10 is connected to the signal base station 1 through a connecting foot 11, and a total of four sliding blocks 10 are slidably arranged on the two arc-shaped tracks 4, and four connecting feet 11 are arranged on the back of the signal base station 1. The four connecting feet 11 are arranged at the four corners of the back of the signal base station 1, and the four connecting feet 11 are fixedly connected to the four sliding blocks 10 in a one-to-one correspondence. A damping sleeve is arranged on the surface of the sliding block 10. When the signal base station 1 slides downward from the highest position of the mounting frame 3, it can slide slowly under the action of the damping sleeve, reducing the impact on the equipment and avoiding damage to the equipment inside the signal base station 1. The side panel 6 is also provided with a rotating notch 8, and a reinforcing plate 9 is arranged on the outer side of the side panel 6, and the reinforcing plate 9 is located at the rotating notch 8.

[0022] The connection plate 5 is provided with a limit assembly 12, which is used to limit the sliding block 10 to slide along the sliding groove 7. The limit assembly 12 is arranged on the upper part of the mounting frame 3. The limit assembly 12 includes a mounting tube 13, which is fixed on the connection plate 5. A spring is arranged inside the mounting tube 13. Limit blocks 14 are slidably arranged at both ends of the mounting tube 13. The two limit blocks 14 correspond to the sliding grooves 7 of the arc track 4 respectively. Under the action of the spring, the end of the limit block 14 away from the mounting tube 13 is located in the sliding groove 7. The end of the limit block 14 away from the mounting tube 13 is an inclined surface 15, and the inclined surface 15 is inclined downward. When the signal base station 1 slides from bottom to top, when the sliding block 10 contacts the inclined surface 15 of the limit block 14 and continues to move upward, the limit block 14 compresses the spring and moves toward the mounting tube 13 until the sliding block 10 passes over the limit block 14, and the limit block 14 is reset under the action of the spring. Under the action of the limit block 14 , the sliding block 10 cannot slide downward, and the signal base station 1 is in a normal working state.

[0023] The mounting frame 3 is also provided with a supporting handle 16, which is rotatably provided at the lower part of the mounting frame 3, and a fixing rod 17 is provided on the supporting handle 16, and a pull rope 18 is provided between the fixing rod 17 and the limit block 14, and one end of the pull rope 18 is provided on the fixing rod 17, and the other end is provided at one end of the limit block 14 located inside the mounting tube 13. When the signal base station 1 needs to be inspected and maintained, by rotating the supporting handle 16 to a horizontal state, the pull rope 18 pulls the limit block 14, so that the sliding block 10 can slide, and drives the signal base station 1 to slide downward to the lowest position.

[0024] A rotation hole 19 is provided below the sliding groove 7, and a limited rotation block 20 is provided in the rotation hole 19. When the sliding block 10 slides into the rotation hole 19, the sliding block 10 can rotate in the rotation hole 19. After the sliding block 10 located below the mounting frame 3 is located in the rotation hole 19, the signal base station 1 is rotated about the rotation hole 19 as an axis, and the sliding block 10 located above the signal base station 1 is rotated out of the rotation notch 8. Under the action of the limited rotation block 20 and the supporting handle 16, the signal base station 1 is in a vertical state.
