[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the utility model provides a subway-specific aerial work vehicle drilling avoidance device, comprising a work vehicle body 1 and a drilling mechanism 4 arranged on the surface of the work vehicle body 1, and a detection avoidance component 2 is arranged on the surface of the work vehicle body 1;

[0027] The detection and avoidance component 2 includes a sleeve rod 21. The sleeve rod 21 is installed on the surface of the work vehicle body 1. A hydraulic rod 22 is installed inside the sleeve rod 21. The telescopic end of the hydraulic rod 22 is connected to the drilling mechanism 4. The surface of the drilling mechanism 4 is sleeved with a protective sleeve 23. The surface of the protective sleeve 23 is installed with multiple connecting rods 24. The connecting rod 24 is connected to the work vehicle body 1. A detection plate 25 is provided in the groove opened on the surface of the protective sleeve 23. The surface of the detection plate 25 close to the protective sleeve 23 is installed with multiple adjusting rods 26. A support rod 27 is installed in the groove opened on the surface of the protective sleeve 23. The adjusting rod 26 is slidably connected to the inside of the support rod 27. A detection module 28 is installed inside the support rod 27. The surface of the protective sleeve 23 is provided with a detection and protection component 3, so that obstacles in the subway tunnel can be detected and processed. After the detection is completed, the drilling mechanism 4 is retracted at the same time to prevent the drilling mechanism 4 from being damaged by obstacles during operation.

[0028] like Figures 1 to 6 As shown, a reset spring 29 is sleeved on the surface of the adjusting rod 26, one end of the reset spring 29 is connected to the support rod 27, and the other end of the reset spring 29 is connected to the adjusting rod 26, so that the position of the adjusting rod 26 can be reset, which greatly improves the use effect of the device.

[0029] Furthermore, the detection plates 25 are evenly distributed on both sides of the protective cover 23, and the detection plates 25 extend to the outside of the protective cover 23, so that obstacles can be detected and processed conveniently, further improving the detection effect of the device.

[0030] like Figures 1 to 6 As shown, the drilling mechanism 4 is slidably connected to the interior of the sleeve rod 21, so that the drilling mechanism 4 can be retracted to prevent obstacles from causing damage to the drilling mechanism 4.

[0031] like Figures 1 to 6 As shown, the detection and protection component 3 includes a conical block 31, and mounting plates 34 are symmetrically installed on the surface of the protective sleeve 23. A movable rod 32 is rotatably connected between the two mounting plates 34, and the movable rod 32 is connected to the conical block 31, so that the device can be protected and obstacles can be detected during the protection process, further improving the use effect of the device.

[0032] It is worth emphasizing that the conical block 31 and the protective sleeve 23 are arranged in an angle structure, so that the protective sleeve 23 can be protected and space for extrusion can be reserved.

[0033] Furthermore, a torsion spring 33 is provided on the surface of the movable rod 32, one end of the torsion spring 33 is connected to the mounting plate 34, and the other end of the torsion spring 33 is connected to the movable rod 32, thereby assisting the movable rod 32 in resetting, further improving the use effect of the device.

[0034] The structure of the motor is prior art and will not be described in detail. Furthermore, the present invention also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its operating principle is already known technology. The model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: When the work vehicle body 1 drives the drilling mechanism 4 to drill in the subway tunnel, the work vehicle body 1 drives the sleeve rod 21 and the drilling mechanism 4 to rotate as a whole, thereby drilling the subway tunnel. When encountering an obstacle, the obstacle squeezes the detection plate 25, and the detection plate 25 is squeezed and slides in the groove opened on the surface of the protective cover 23. During the sliding process, the detection plate 25 drives the adjustment rod 26 to slide inside the support rod 27, and the adjustment rod 26 squeezes the return spring 29 inside the support rod 27. At this time, the return spring 29 is deformed, and the return spring 29 can drive the detection plate 25 to reset when it is not subjected to the squeezing force, thereby further improving the use effect of the device. At this time, the adjustment rod 26 squeezes the detection module 28 during the sliding process, so that the detection module 28 sends a signal to the controller. At this time, the main controller sends a signal to the hydraulic rod 22, so that the telescopic end of the hydraulic rod 22 drives the drilling mechanism 4 to slide inside the sleeve rod 21, so that the drilling mechanism 4 is retracted to the inside of the sleeve rod 21, so that the drilling mechanism 4 avoids the obstacle;

[0036] When detecting an obstacle, the conical block 31 can also be squeezed by the obstacle. At this time, the conical block 31 drives the movable rod 32 to rotate on the surface of the mounting plate 34. The movable rod 32 drives the torsion spring 33 to deform during the rotation process. The torsion spring 33 can reset the position of the conical block 31, thereby further improving the use effect of the device. The conical block 31 can protect the protective sleeve 23 to prevent the protective sleeve 23 from positional displacement during the movement. When the conical block 31 is squeezed and rotated, the conical block 31 squeezes the detection module 2 on the surface of the protective sleeve 23, thereby starting the hydraulic rod 22 to retract.

[0037] The working vehicle body 1, drilling mechanism 4 and detection module 28 in the device are mature existing technologies. The detection module 28 is a pressure sensor device, which is used to sense the force of the obstacle squeezing, so as to perform subsequent operations. The drilling mechanism 4 is used in conjunction with the drilling rod and the motor to drill holes in the subway tunnel. The working vehicle body 1 is hinged to the drilling mechanism 4, and the angle of the drilling mechanism 4 is adjusted by the electric push rod.
