Between the lower plate 410 and the extension edge 407, a spring 411 is fixed. In the middle between the upper plate 409 and the lower plate 410, a gear sleeve 412 penetrates and is rotatably connected. At the top inside the gear sleeve 412, there is a hexagonal opening 413 that cooperates with the nut of the expansion bolt 601. At the bottom inside the gear sleeve 412, there is an enlarged diameter opening 414 that cooperates with the hammer head 403. At one end of the upper plate 409 away from the slide rod 408, a driving motor 415 is fixed. The output end of the driving motor 415 is fixed with a driving gear 416 that meshes with the gear sleeve 412. The wire guide 5 includes a third lifting cylinder 501. The third lifting cylinder 501 is fixed on the circumferential side of the rotary table 1 through an electric slide 502. The sliding direction of the electric slide 502 is parallel to the axis direction of the rotary table 1. The telescopic end of the third lifting cylinder 501 is connected with a cable guide wheel set 504 through a cross plate 503.

[0021] Among them, a rotary drive is connected to the outside of the rotary table 1. The rotary table 1 is arranged on a lifting platform or the lifting arm of a tracked vehicle.

[0022] Among them, as Figure 1 shown, the distance measuring mechanism 2 is composed of several infrared distance sensors, and several infrared distance sensors are linearly distributed along the axial direction of the rotary table 1.

[0023] Among them, as Figure 1 shown, the drilling mechanism 3 includes a first lifting cylinder 301. The telescopic end of the first lifting cylinder 301 is fixed with a motor 302, and the output end of the motor 302 is fixed with a drill bit 303.

[0024] Among them, as Figure 1 shown, an inner cylinder is provided inside the rotary table 1. A pipe-passing channel is formed between the inner cylinder and the rotary table 1. On the circumferential side of the rotary table 1, there is an opening 101 communicating with the pipe-passing channel.

[0025] Among them, asFigure 1 As shown, the circumferential side of the rotary table 1 is provided with four flat surfaces 102, and the distance measuring mechanism 2, the drilling mechanism 3, the support mounting mechanism 4, and the cable support 5 are respectively mounted on the four flat surfaces 102.

[0027] Among them, a magnet is fixedly embedded inside the L-shaped support 405, and the optical cable Z-shaped support 6 is fixedly adsorbed in the L-shaped support 405 through the magnet.

[0028] The working principle of the present invention is as follows: Control the rotary table 1 to approach the installation surface, measure the distance from the installation surface through the distance measuring mechanism 2. After the distance measurement is completed, rotate the rotary table 1 by a certain angle, rotate the drilling mechanism 3 to a position opposite to the measurement point, and open a hole on the installation surface through the first lifting cylinder 301, the motor 302, and the drill bit 303. After the hole opening is completed, control the motor 302 to stop and control the first lifting cylinder 301 to reset. Then drive the rotary table 1 to rotate by a certain angle again to make the expansion bolt 601 of the optical cable Z-shaped support 6 opposite to the hole opening position. Control the second lifting cylinder 402 to lift the L-shaped support 405, the gear sleeve 412, and the optical cable Z-shaped support 6 together. During this process, strike the expansion bolt 601 with the hydraulic hammer 401 until the top of the optical cable Z-shaped support 6 fits the installation surface. At this time, the hydraulic hammer 401 stops and moves away from the expansion bolt 601. Control the driving motor 415 to drive the main gear 416 to rotate, so as to tighten the nut of the expansion bolt 601. At this time, the installation of the optical cable Z-shaped support 6 is completed. Control the second lifting cylinder 402 to sink and reset to disengage from the optical cable Z-shaped support 6. Then drive the rotary table 1 to rotate by a certain angle, drive the optical cable to move above the horizontal side part of the optical cable Z-shaped support 6 through the cable guide wheel set 504, and the optical cable can be clamped in the optical cable Z-shaped support 6 through the cooperation of the electric sliding table 502 and the third lifting cylinder 501.
