The shielding member 5 is used to shield the explosives and prevent the explosives from bursting out of the transfer plate 3. The shielding member 5 includes a mounting rod 51 and a first shielding net 52 arranged on the transfer plate 3. A plurality of mounting rods 51 are provided and hingedly arranged on the transfer plate 3. The mounting rods 51 are located on the side of the transfer plate 3 away from the tunnel face. The hinge points of the plurality of mounting rods 51 are all located on the center line of the transfer plate 3. The first shielding net 52 is fan-shaped and a plurality of them are provided. The first shielding net 52 is fixedly arranged between adjacent mounting rods 51, close to the One side of the first shielding net 52 near the transfer plate 3 is fixed on the transfer plate 3; before the blasting of the face, when the transfer plate 3 abuts against the face, the mounting rod 51 is rotated, and the mounting rod 51 drives the first shielding net 52 to unfold. After the first shielding net 52 is unfolded, a partition is formed in the tunnel 1, which is convenient for blocking the explosives. During the blasting process, the collapsed rocks move toward the first shielding net 52 and hit the first shielding net 52, and then fall on the transfer plate 3; at the same time, the first shielding net 52 is a wire mesh, which reduces the possibility of damage to the first shielding net 52 due to shock waves.

[0021] Reference Figure 1 and Figure 2In the embodiment of the present application, in order to facilitate the unfolding of the first shielding net 52, a first mounting shaft and a second mounting shaft are provided on the transfer plate 3, the first mounting shaft and the second mounting shaft are coaxial and located on the center line of the transfer plate 3, the mounting rod 51 away from the face is fixedly provided on the second mounting shaft, and the remaining mounting rods 51 are fixedly provided on the first mounting shaft, and a first motor 53 is provided on the transfer plate 3, the second mounting shaft is coaxially provided on the first motor 53, and the first motor 53 is located on the side of the first shielding net 52 away from the face; when the first shielding net 52 is unfolded, the first motor 53 is started, the first motor 53 drives the second mounting shaft to rotate, the rotation of the second mounting shaft drives the mounting rod 51 to rotate and drives the corresponding first shielding net 52 to unfold, and when the first shielding net 52 is flattened, it drives the adjacent mounting rod 51 to rotate to unfold the first shielding net 52, and the operation is simple and convenient.

[0022] Reference Figure 2 and Figure 3 In order to reduce the possibility of explosives falling from the side of the transfer plate 3 when the explosives are transferred on the transfer plate 3, a covering member is provided on the transfer plate 3. The covering member is used to cover the explosives on the transfer plate 3 when the transfer plate 3 transfers the explosives. The covering member includes a covering rod 6 fixedly arranged on the mounting rod 51. The covering rod 6 corresponds to the mounting rod 51 one by one. The length direction of the covering rod 6 is perpendicular to the mounting rod 51 and perpendicular to the tunnel face. The covering member also includes a second shielding net 7 arranged between adjacent covering rods 6; when the first motor 53 drives the mounting rod 51 to rotate, the mounting rod 51 drives the corresponding covering rod 6 to rotate, and an arched enclosure is formed on the transfer plate 3, thereby reducing the possibility of explosives falling through the side of the transfer plate 3.

[0023] Reference Figure 2 and Figure 4 After the tunnel 1 is blasted, the explosives usually fall on one end of the transfer plate 3. At this time, when the transfer plate 3 moves, it is easy to cause the explosives to fall. Therefore, in the embodiment of the present application, the transfer plate 3 includes a first plate body 31 and a second plate body 32. The second plate body 32 is located above the first plate body 31 and has an area smaller than the first plate body 31.

The first plate body 31 is slidably arranged on the rail 2, and the second plate body 32 is used to receive the explosives. The mounting rod 51 is arranged on the second plate body 32. The first shielding net 52 and the second shielding net 7 form an arched enclosure on the second plate body 32. The second plate body 32 is hingedly arranged on the first plate body 31. The hinge axis of the second plate body 32 is parallel to the width direction of the tunnel 1. The transfer plate 3 also includes a first driving member for driving the second plate body 32 to rotate; Reference Figure 2 and Figure 4Furthermore, a third mounting shaft 8 is rotatably provided on the first plate 31, and the end of the second plate 32 away from the face and the bottom thereof is fixedly provided on the third mounting shaft 8, and the first driving member comprises a hydraulic cylinder 9 provided on the first plate 31, and the piston rod of the hydraulic cylinder 9 abuts against the bottom of the second plate 32, and the body of the hydraulic cylinder 9 is away from the third mounting shaft 8. After the tunnel 1 is blasted, when the explosive falls on the transfer plate 3 and becomes stable, the hydraulic cylinder 9 is started, and the piston rod of the hydraulic cylinder 9 slides and abuts against the second plate 32, thereby driving the second plate 32 to rotate toward the entrance of the tunnel 1, and the rotation of the second plate 32 drives the explosive to slide toward one side, thereby reducing the possibility of the explosive falling; and after the second plate 32 rotates, it maintains an inclined state, thereby reducing the possibility of the explosive falling during the movement of the transfer plate 3.

[0024] Reference Figure 2 and Figure 4 Because the extension direction of the tunnel 1 is straight or curved, the transfer plate 3 is easy to get stuck at the curved part of the tunnel 1. Therefore, in the embodiment of the present application, the first plate body 31 includes a plurality of assembly plates 311, and the plurality of assembly plates 311 are all supported on the rail 2, with gaps between adjacent assembly plates 311. A traction rope 312 is provided between adjacent assembly plates 311 and fixedly connected by the traction rope 312. The traction rope 312 is formed by winding a steel wire rope. Under the action of the assembly plate 311, the width of a single assembly plate 311 is shortened, thereby reducing the possibility of the assembly plate 311 getting stuck, and facilitating the movement of the transfer plate 3.

[0025] Reference Figure 2 In the embodiment of the present application, the driving device 4 includes a driving wheel 41 arranged at the bottom of the assembly plate 311, the peripheral wall of the driving wheel 41 is concave and clamped on the rail 2, and the driving device 4 also includes a second motor 42 for driving the driving wheel 41 to rotate; when the transfer plate 3 moves, the second motor 42 is started, and the second motor 42 drives the driving wheel 41 to rotate, and the driving wheel 41 drives the transfer plate 3 to move on the rail 2, thereby driving the explosives to be moved out of the tunnel 1, and the operation is simple and convenient.

[0026] Reference Figure 2 In the embodiment of the present application, there are at least four driving wheels 41 on an assembly plate 311, and they are arranged in a rectangular array; there are at least four driving wheels 41 on the assembly plate 311, which makes it easy to lay the assembly plate 311 flat on the rail 2, thereby reducing the possibility of the assembly plate 311 tipping over and facilitating the removal of explosives.

[0027] The implementation principle of a device for quickly removing explosives from a tunnel according to the embodiment of the present application is as follows: Before the tunnel 1 face is blasted, the transfer plate 3 is first driven to slide along the rail 2 and abut against the face, and then the first shielding net 52 is unfolded. When the first shielding net 52 is unfolded, the first motor 53 is started, and the first motor 53 drives the second installation shaft to rotate. The rotation of the second installation shaft drives the installation rod 51 to rotate and drive the corresponding first shielding net 52 to unfold. When the first shielding net 52 is flattened, it drives the adjacent installation rod 51 to rotate and unfold the first shielding net 52; at the same time, the installation rod 51 drives the corresponding covering rod 6 to rotate, and an arched enclosure is formed on the transfer plate 3.

[0028] Then blasting is carried out. When the explosive falls on the transfer plate 3 and stabilizes, the hydraulic cylinder 9 is started. The piston rod of the hydraulic cylinder 9 slides and abuts against the second plate body 32, thereby driving the second plate body 32 to rotate toward the entrance of the tunnel 1. The rotation of the second plate body 32 drives the explosive to slide to one side.

[0029] Subsequently, the second motor 42 is started, and the second motor 42 drives the driving wheel 41 to rotate, and the driving wheel 41 drives the transfer plate 3 to move on the rail 2. In the above process, the time for loading explosives and vehicle entry and exit is reduced, thereby improving the transportation efficiency of explosives.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
