Working mode: It is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a transfer mechanism. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks up the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good tunnel quality, but it is expensive, has a complex structure and suffers large losses.

[0003] The tunnel boring machine used in underground coal mines has a great safety hazard during its operation because the cutting head, i.e., the "gun head", is in a state of moving left and right, and the tunnel boring machine is often in a forward and backward state. The risk value is very high and it is very easy to cause harm to personnel. From a system perspective, the tunnel boring machine itself has defects and cannot sense the entry of personnel in a timely and rapid manner. At the same time, it cannot stop working immediately due to the misinterpretation of other personnel. It can be said that there is an insurmountable hidden danger. In addition, there is a kind of arbitrariness and inaccuracy in the manual setting of alarms. Therefore, an induction-type tunnel boring machine early warning protection structure is proposed to solve the above-mentioned problems. Utility Model Content

Limiting grooves are provided on the left and right sides of the thermoluminescence control sensor probe 8.

[0023] In this embodiment, the limiting assembly includes a cavity 9 opened inside the movable block 7, and the cavity 9 is internally slidably connected to a limiting rod 10, the size of the limiting groove is adapted to the size of the limiting rod 10, and a handle 13 for convenient pulling is fixedly connected to the limiting rod 10, and a limiting spring 11 is sleeved on the outer side of the limiting rod 10, and one side of the limiting spring 11 is fixedly connected to the inner wall of the cavity 9, and a connecting plate 12 is fixedly connected to the outer side of the limiting rod 10, and one side of the limiting spring 11 is fixedly connected to one side of the connecting plate 12.

[0024] The working principle of the above embodiment is:

[0025] The induction-type early warning protection structure of the tunnel boring machine is provided with a protection mechanism. When a worker enters the sensing range of the warning area, the infrared heat released by the human body will be immediately detected by the thermoluminescence control sensor probe 8, and the detected infrared heat will be converted into an electrical signal, which will be input into the sound and light signal device 3 to send out a sound and light alarm. After receiving the alarm sound and light signal, the worker quickly leaves the warning area and continues to move forward to trigger the secondary alarm, which is linked with the emergency stop of the tunnel boring machine body 1 to stop the tunnel boring machine body 1 directly, and start the motor 5. The output shaft of the motor 5 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the movable block 7 and the thermoluminescence control sensor probe 8 to move forward and backward. By setting the guide rod 13, the movable block 7 is limited and supported, which increases the safety of the tunnel boring machine. The stability of the thermoluminescence control sensor probe 8 during movement is increased, thereby improving the protection range of the thermoluminescence control sensor probe 8. By setting the protection plate 2, debris can be prevented from causing damage to the thermoluminescence control sensor probe 8 and the sound and light signal device 3. By setting a limit component, the two handles 14 are pulled back to back, and the handles 14 drive the two limit rods 10 to move back to back. At the same time, the connecting plate 12 squeezes the limit spring 11, so that the limit rod 10 is pulled out of the limit groove provided on the thermoluminescence control sensor probe 8, so as to facilitate the rapid disassembly of the thermoluminescence control sensor probe 8, and then facilitate the maintenance and replacement of the thermoluminescence control sensor probe 8, which is convenient for users to use and improves the practicality of the tunnel boring machine.
