In use, the first connecting component 1 is fixedly connected to the tunneling machine, and the second connecting component 2 is movably connected to the bridge transfer machine, thereby enabling relative rotation between the tunneling machine and the bridge transfer machine.

[0019] Based on the above structure, when this connecting device is used to connect the tunneling machine and the bridge transfer machine, by movably connecting the second connecting component 2 to the first connecting component 1 and movably connecting the second connecting component 2 to the bridge transfer machine, the bridge transfer machine and the tunneling machine are movably connected. When constructing the reversing chamber using this structure, the bridge transfer machine can rotate relative to the tunneling machine from -90° to 90°, which can meet the construction requirements. It does not require replacing the explosion-proof loader, avoids the cumbersome production process caused by repeatedly dismantling and installing the bridge transfer machine, and improves construction safety.

[0020] like Figure 2 , Figure 3 As shown, in some embodiments of this application, the first connecting component 1 includes a first connecting plate 11 and a first ear plate 12 disposed on the first connecting plate 11.

[0021] like Figure 5 , Figure 6 As shown, in some embodiments of this application, the second connecting component 2 includes a second connecting plate 21, a second ear plate 22, and a universal joint 23. The second ear plate 22 and the universal joint 23 are respectively disposed on opposite sides of the second connecting plate 21, and the second ear plate 22 is movably connected to the first ear plate 12.

[0022] In use, the first connecting plate 11 is connected to the tunneling machine, the first ear plate 12 is movably connected to the second ear plate 22, and the universal joint 23 is movably connected to the bridge transfer machine.

[0023] In some embodiments of this application, the first ear plate 12 is provided with a first connecting hole 121, and the second ear plate 22 is provided with a second connecting hole 221. A rotating pin is inserted into the first connecting hole 121 and the second connecting hole 221. The rotating pin enables the first ear plate 12 and the second ear plate 22 to be rotatably connected, and facilitates the assembly and disassembly of the first ear plate 12 and the second ear plate 22.

[0024] In some embodiments of this application, two first ear plates 12 are provided, and the two first ear plates 12 are provided on both sides of the first connecting plate 11. By providing two first ear plates 12, the connection strength between the first connecting plate 11 and the second connecting plate 21 is increased.

[0025] In some embodiments of this application, two second ear plates 22 are provided. The positions of the two second ear plates 22 on the second connecting plate 21 are adapted to the first ear plate 12. The two second ear plates 22 are respectively close to the two first ear plates 12. In use, one first ear plate 12 and one second ear plate 22 are respectively connected by two rotating pins.

[0026] In some embodiments of this application, the first connecting hole 121 is disposed on the first ear plate 12 off-center from the center of the first ear plate 12; specifically, when the tunneling machine is connected to the bridge transfer machine, the connecting device between the two is in a parallel or inclined position, not vertically upward. The first connecting hole 121 is disposed on the first ear plate 12 off-center to facilitate disassembly and assembly and stress.

[0027] like Figure 4 As shown, in some embodiments of this application, the first connecting plate 11 is also provided with a third connecting hole 111. The first connecting plate 11 is connected to the tunneling machine by passing a bolt or pin through the third connecting hole 111, which facilitates disassembly and assembly.

[0028] In some embodiments of this application, two third connection holes 111 are provided to increase the connection stability between the first connection plate 11 and the tunneling machine.

[0029] The specific method of using the steerable connection device provided in this embodiment is as follows: In use, the first connecting plate 11 is connected to the tunneling machine by inserting two bolts or pins into the two third connecting holes 111. Then, the second connecting holes 221 on the two second ear plates 22 are aligned with the first connecting holes 121 on the two first ear plates 12. The two first ear plates 12 and the two ear plates 22 are connected by two rotating pins respectively. At this time, the second connecting plate 21 can rotate relative to the first connecting plate 11 along the axis of the rotating pin. That is, the bridge transfer machine is not restricted by the connection relationship between the second connecting plate 21 and the first connecting plate 11 when it moves up and down relative to the tunneling machine.

[0030] The universal joint on the second connecting plate 21 is connected to the bridge transfer machine, so that the bridge transfer machine can rotate flexibly relative to the tunneling machine. This can meet the construction needs when constructing the reversing chamber without replacing the explosion-proof loader. It can avoid the cumbersome production process caused by repeatedly dismantling and installing the bridge transfer machine, and improve construction safety.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
