[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] Reference Figure 1-13 This invention provides a device for automatically laying sensor cables along an I-beam arch, comprising:
[0040] A fixed plate 1 has limiting mechanisms fixed to its top two sides. One of the limiting mechanisms has a cable fixing mechanism fixed to its end face. The middle two sides of the fixed plate 1 are rotatably connected to guide wheels 3 via two fixed positions 2. A transmission mechanism is set below each of the two limiting mechanisms. A drive plate 4 is fixed to the bottom side of the fixed plate 1. Two transmission mechanisms are fixed to the top surface of the drive plate 4. The two transmission mechanisms are connected by a transmission worm gear 5. The two ends of the transmission worm gear 5 are rotatably connected by a support seat. A drive mechanism is fixed to the top surface of the drive plate 4. The drive mechanism is connected to one of the transmission mechanisms. One end of a protruding plate 6 is fixed to the side of the drive plate 4. The other end of the protruding plate 6 has a cavity. An adjustment mechanism is set in the cavity. The drive mechanism is connected to a wireless controller 7 via a signal.
[0041] This invention is simple to operate and highly automated, which can effectively reduce the workload of operators, improve the efficiency of laying external cables for sensors, and ensure the safety of operators when laying external cables for sensors along the I-beam arch frame body 36. The external cable laying method of this invention can reduce the damage to external cables caused by the strong impact of shotcrete, thereby improving the success rate of sensor installation.
[0042] The scheme is further optimized. The limiting mechanism includes a limiting plate 8, which is fixedly connected to a fixed plate 1. A telescopic rod 9 is provided through the top surface of the limiting plate 8. One end of the telescopic rod 9 is fixedly connected to a limiting block 10, which abuts against the top surface of the limiting plate 8. The other end of the telescopic rod 9 is fixedly connected to an upper bracket 11 after passing through the limiting assembly. The upper bracket 11 is rotatably connected to a roller 12.
[0043] The fixing plate 1 is made of lightweight metal. A limiting plate 8 for fixing the roller 12 is provided at the top of the fixing plate 1. This limiting plate 8 has through holes that slide in contact with the telescopic rod 9. The surface of the roller 12 is covered with an anti-slip rubber layer. The roller 12 can be retracted via the telescopic rod 9 to abut against the I-beam arch frame body 36, and cooperates with the transmission wheel 17 to clamp the outer flange plate of the I-beam arch frame. The limiting block 10 can limit the top of the telescopic rod 9 to prevent it from falling off.
[0044] Further optimization of the scheme: the limiting component includes a square shell 13, the top of the square shell 13 is fixedly connected to the bottom surface of the limiting plate 8, a spring 14 is provided inside the square shell 13, a telescopic rod 9 passes through the square shell 13, and the spring 14 is sleeved on the telescopic rod 9. A square clip 15 is fixedly connected to the outer wall of the telescopic rod 9, and the outer wall of the square clip 15 is adapted to the inner cavity of the square shell 13.
[0045] The inner cavity of the square shell 13 is adapted to the square clip 15, which prevents the telescopic rod 9 from rotating in the horizontal direction and improves the stability of the roller 12. The spring 14 abuts against the square clip 15, thereby realizing the telescopic rod 9's extension and retraction action.
[0046] The scheme is further optimized. The transmission mechanism includes a lower bracket 16, which is fixed to the top surface of the drive plate 4. A transmission wheel 17 is rotatably connected to the top of the lower bracket 16. Worm gears 18 are fixed to both sides of the transmission wheel 17 of one transmission mechanism. A worm gear 18 is fixed to one side of the transmission wheel 17 of the other transmission mechanism. The two worm gears 18 located on the same side of the two transmission wheels 17 mesh with the two ends of the transmission worm 5. The other worm gear 18 is connected to the drive mechanism for transmission.
[0047] The surface of the transmission wheel 17 is provided with an anti-slip rubber layer. The driving mechanism drives one of the transmission wheels 17 to rotate. The other worm gear 18 of the transmission wheel 17 is driven by the transmission worm 5 to realize the rotation of the other transmission wheel 17, thereby realizing the displacement of the entire device on the I-beam arch frame.
[0048] The scheme is further optimized. The drive mechanism includes a servo motor 19, which is fixed to the drive plate 4 by a positioning component. The servo motor 19 is connected in series with a signal receiver 20, a rechargeable power supply 21 and a power switch 22 via wires. The signal receiver 20, the rechargeable power supply 21 and the power switch 22 are all fixed to the drive plate 4. The output end of the servo motor 19 is set as a worm gear structure. The output end of the servo motor 19 is rotatably connected to the second support base 38 and meshes with the worm wheel 18.
[0049] The wireless controller 7 sends commands to the signal receiver 20, which in turn drives the servo motor 19 to control the entire device. The servo motor 19, signal receiver 20, rechargeable power supply 21, and power switch 22 are all existing technologies, so they will not be described in detail.
[0050] The solution is further optimized. The positioning component includes a horseshoe-shaped buckle 23, which is sleeved on the servo motor 19 and is fixed to the drive plate 4 by bolts.
[0051] The servo motor 19 is fixed by the horseshoe-shaped buckle 23.
[0052] The solution is further optimized. The cable fixing mechanism includes a vertical plate 24, which is fixed to the end face of one of the limiting plates 8. The side of the vertical plate 24 is provided with several cable slots 25 at equal intervals. Cable clips 26 are provided in the cable slots 25. The cable clips 26 are designed with an L-shaped structure. The short side end face of the cable clips 26 is provided with an arc-shaped opening 27. The bent part of the cable clips 26 is rotatably connected to the inner wall of the cable slots 25 through a pivot 28.
[0053] The cable slot 25 and cable clip 26 limit the cable position and fix its position between the arc-shaped opening 27 and the cable slot 25.
[0054] Further optimization of the scheme: the adjustment mechanism includes a connecting rod 29, one end of which is located in the cavity. A strip tooth 30 is provided on the side of the connecting rod 29, and the strip tooth 30 is located in the cavity. A gap is left between the side of the connecting rod 29 with the strip tooth 30 and the cavity. A protrusion 31 is fixedly connected to one side of the bottom surface of the cavity, and the protrusion 31 is located in the gap. The top and bottom surfaces of the convex plate 6 are respectively provided with corresponding through holes. An adjustment knob 32 is slidably contacted in the two through holes. A gear 33 is fixedly connected to the middle of the adjustment knob 32. The gear 33 meshes with the strip tooth 30. The top of the adjustment knob 32 is set as a cylindrical structure. An adjustment component is fixedly connected to the other end of the connecting rod 29. The protrusion 31 corresponds to the gear 33.
[0055] Rotating the adjustment knob 32 rotates the gear 33. The gear 33 meshes with the rack tooth 30, thereby displacing the entire connecting rod 29. After the concave pulley 35 and guide wheel 3 fix the I-beam arch frame body 36, press the adjustment knob 32 down forcefully to lock the gear 33 of the adjustment knob 32 into place by the protrusion block 31, thus locking the adjustment knob 32.
[0056] The scheme is further optimized. The adjustment component includes a support rod 34. The bottom of the support rod 34 is fixedly connected to the connecting rod 29, and the top of the support rod 34 is rotatably connected to a concave pulley 35.
[0057] The recess on the concave pulley 35 can limit the edge of the flange.
[0058] The wireless controller 7 is used to control the movement of the automatic sensor cable laying device. The wireless controller 7 is equipped with a start / stop button 39, a forward button 40, a reverse button 41, a signal transmitter 42, and a removable battery 43.

Then, lift the two rollers 12 upward to create a gap between the two rollers 12 and the two drive wheels 17. The automatic sensor cable laying device will clamp the outer flange plate of the I-beam arch frame body 36 through the gap. Finally, insert the connecting rod 29 into the protruding plate 6 on one side of the bottom of the fixing plate 1. Rotate the adjusting knob 32 to clamp the flange plate of the I-beam arch frame body 36 between the two guide wheels 3 and the concave pulley 35. Press the adjusting knob 32 downward to engage the gear 33 with the protruding block 31, thereby locking the connecting rod 29.
[0062] S3. Laying external cables: Turn on the power switch 22 and use the wireless controller 7 to control the automatic sensor cable laying device to move along the I-beam arch body 36 and lay the external cables along the web of the I-beam arch body 36 to the installed sensor pin lines.
[0063] S4. Connect the external cable to the sensor pin: Lift the cable clip 26, take out the required external sensor cable from the cable slot 25, and connect it to the sensor pin.

Repeat step S4 to connect the external cables to the sensor pin lines. If the number of external cables carried by the automatic sensor cable laying device is insufficient, control the automatic sensor cable laying device to return to the bottom of the I-beam arch body 36 to reload the external cables.
[0065] S6.
