[0007] According to the embodiment of the transfer machine provided by the present invention, the first electric control box is directly arranged on the frame assembly, and the staff can control the first roller and / or the second roller without going to the position where the electric control box is arranged on the tunnel boring machine, which is conducive to ensuring the continuity of transportation and transfer, shortening the auxiliary working hours, and improving the working efficiency. In addition, by setting the alarm device and the emergency stop button, the alarm information can be received in time in special circumstances such as material jamming, and the machine can be stopped in an emergency.

[0008] Specifically, the transfer machine includes a frame assembly, a first roller, a second roller, a conveyor belt, a first electric control box, an alarm device and an emergency stop button. Among them, the frame assembly has a first end and a second end arranged opposite to each other. The first end of the frame assembly is used to connect with the tunneling machine, and the second end of the frame assembly is used to connect with the transportation equipment. Further, the first roller is rotatably arranged at the first end of the frame assembly, which can be understood as the first roller is arranged at the first end of the frame assembly, and the first roller can rotate relative to the frame assembly. The second roller is rotatably arranged at the second end, which can be understood as the second roller is arranged at the second end of the frame assembly, and the second roller can rotate relative to the frame assembly. Further, the conveyor belt is sleeved on the first roller, and the conveyor belt is sleeved on the second roller. The first roller and the second roller are both frictionally matched with the conveyor belt. In other words, the first roller is in contact with the conveyor belt, and there is friction between the first roller and the conveyor belt. When the first roller is an active roller, the rotation of the first roller can drive the conveyor belt to move; when the first roller is a driven roller, the movement of the conveyor belt can drive the first roller to rotate. The second roller is in contact with the conveyor belt, and there is friction between the second roller and the conveyor belt. When the second roller is an active roller, the rotation of the second roller can drive the conveyor belt to move; when the second roller is a driven roller, the movement of the conveyor belt can drive the second roller to rotate.

[0009] Further, the first electric control box is arranged on the frame assembly. The first roller and / or the second roller are electrically connected to the first electric control box. Optionally, of the two rollers, the first roller is an active roller, the second roller is a driven roller, and the first electric control box is electrically connected to the first roller; or, of the two rollers, the second roller is an active roller, the first roller is a driven roller, and the first electric control box is connected to the second roller; or, the first roller and the second roller are both active rollers, and the first roller and the second roller are both electrically connected to the first electric control box.

Optionally, the first electric control box is a flameproof electric control box. Further, the first electric control box controls the speed of the first roller and / or the second roller not to exceed the first speed threshold and not to be lower than the second speed threshold. In other words, the first electric control box is used to control the speed of the active roller (the first roller and / or the second roller) between the first speed threshold and the second speed threshold. When the speed of the active roller is between the first speed threshold and the second speed threshold, the transfer machine can work normally and transport the material at a stable speed.

[0010] Further, the alarm device is arranged on the frame assembly, and the alarm device is electrically connected to the first electric control box. When the rotation speed of the first roller and / or the second roller exceeds the first rotation speed threshold or is lower than the second rotation speed threshold, the alarm device performs an alarm operation. In other words, when the rotation speed of the first roller and / or the second roller is abnormal due to material jamming or other special circumstances, the alarm device performs an alarm operation, so that the staff can receive the alarm information in time. Further, the emergency stop button is arranged on the frame assembly, and the emergency stop button is electrically connected to the first electric control box. The emergency stop button enables the first electric control box to control the first roller and / or the second roller to stop rotating to achieve emergency shutdown. It is worth noting that the alarm operation performed by the alarm device can specifically be emitting light or making a sound, etc. The number of emergency stop buttons is at least one, that is, the emergency stop buttons can be one, two or more.

The first end 1111 of the frame assembly 110 is used to connect with the tunnel boring machine 210, and the second end 1141 of the frame assembly 110 is used to connect with the transport equipment 220. Further, the first roller 121 is rotatably arranged at the first end 1111 of the frame assembly 110, which can be understood as the first roller 121 is arranged at the first end 1111 of the frame assembly 110, and the first roller 121 can rotate relative to the frame assembly 110. The second roller 122 is rotatably disposed at the second end 1141. It can be understood that the second roller 122 is disposed at the second end 1141 of the frame assembly 110, and the second roller 122 can rotate relative to the frame assembly 110. Further, the conveyor belt 123 is sleeved on the first roller 121, and the conveyor belt 123 is sleeved on the second roller 122. The first roller 121 and the second roller 122 are both frictionally matched with the conveyor belt 123. In other words, the first roller 121 is in contact with the conveyor belt 123, and there is friction between the first roller 121 and the conveyor belt 123. When the first roller 121 is an active roller, the rotation of the first roller 121 can drive the conveyor belt 123 to move; when the first roller 121 is a driven roller, the movement of the conveyor belt 123 can drive the first roller 121 to rotate. The second roller 122 is in contact with the conveyor belt 123, and there is friction between the second roller 122 and the conveyor belt 123. When the second roller 122 is an active roller, the rotation of the second roller 122 can drive the conveyor belt 123 to move; when the second roller 122 is a driven roller, the movement of the conveyor belt 123 can drive the second roller 122 to rotate.

[0064] Furthermore, if Figure 6As shown, the first electric control box 131 is arranged on the frame assembly 110. The first roller 121 and / or the second roller 122 are electrically connected to the first electric control box 131. Optionally, of the two rollers, the first roller 121 is an active roller, the second roller 122 is a driven roller, and the first electric control box 131 is electrically connected to the first roller 121; or, of the two rollers, the second roller 122 is an active roller, the first roller 121 is a driven roller, and the first electric control box 131 is connected to the second roller 122; or, the first roller 121 and the second roller 122 are both active rollers, and the first roller 121 and the second roller 122 are both electrically connected to the first electric control box 131. Optionally, the first roller 121 can be reversed, that is, the rotation direction is changed to adjust the transport direction of the conveyor belt 123. Optionally, the first electric control box 131 is a flameproof electric control box. Further, the first electric control box 131 controls the rotation speed of the first roller 121 and / or the second roller 122 to be not more than the first rotation speed threshold and not less than the second rotation speed threshold. In other words, the first electric control box 131 is used to control the rotation speed of the active roller (the first roller 121 and / or the second roller 122) between the first rotation speed threshold and the second rotation speed threshold. When the rotation speed of the active roller is between the first rotation speed threshold and the second rotation speed threshold, the transfer machine 100 can work normally and transport the material at a stable speed.

[0065] Further, the alarm device 133 is provided on the frame assembly 110, and the alarm device 133 is electrically connected to the first electric control box 131. When the rotation speed of the first roller 121 and / or the second roller 122 exceeds the first rotation speed threshold or is lower than the second rotation speed threshold, the alarm device 133 performs an alarm operation. In other words, when the rotation speed of the first roller 121 and / or the second roller 122 is abnormal due to material jamming or other special circumstances, the alarm device 133 performs an alarm operation, so that the staff can receive the alarm information in time. Further, the emergency stop button 134 is provided on the frame assembly 110, and the emergency stop button 134 is electrically connected to the first electric control box 131. The emergency stop button 134 enables the first electric control box 131 to control the first roller 121 and / or the second roller 122 to stop rotating, so as to achieve an emergency stop. It is worth noting that the alarm operation performed by the alarm device 133 can specifically be emitting light or making a sound.

[0067] In the technical solution defined in the present invention, the first electric control box 131 is directly arranged on the frame assembly 110, and the staff can control the first roller 121 and / or the second roller 122 without going to the position where the electric control box is arranged on the tunnel boring machine 210, which is conducive to ensuring the continuity of transportation and reprinting, shortening the auxiliary working hours, and improving the working efficiency. In addition, by arranging the alarm device 133 and the emergency stop button 134, the alarm information can be received in time in special circumstances such as material jamming, and the emergency stop can be achieved.

[0068] In another embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the transfer machine 100 further includes a shock absorbing device 132.
