[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0021] The following combination Figs. 1 to 3 The utility model is described in detail.
[0022] A tunneling device for a non-blasting face includes a tunnel 1, a face segmentation 101 provided at one end of the tunnel 1, a roadheader 2 connected to the middle of the tunnel 1, a movable base 201 provided at the bottom of the roadheader 2, a rotating roller 202 connected to one side of the top of the roadheader 2, a mandrel 203 provided on one side of the rotating roller 202, a displacement groove 205 provided at the top of the roadheader 2, a drag assembly connected to the middle of the displacement groove 205, and the drag assembly moving along the displacement groove 205. The face segmentation 101 is achieved by cutting the face into a mesh shape using an oil saw, and the rotating roller 202 includes a transmission wheel 2021 provided on the side of the opening where the roadheader 2 is connected to the rotating roller 202. The transmission wheel 2021 is connected via a motor, and the transmission wheel 2021 meshes with the tooth marks of the rotating roller 202.
[0023] First, when it is necessary to excavate the tunnel face, the face is cut into a mesh by an oil saw or other equipment, and then the movable base 201 is moved and lifted to tilt the top rod 203 into the gap between the cut meshes. Then, due to the hydraulic telescopic setting of the top rod 203, it will be extended by hydraulic pressure, and because of the tilted setting of the top rod 203, pressure will be applied to the face cut out above, forcing this part of the face to bend upward, so that one end of the face will break, thereby completing the separation and dismantling of part of the face, and then taking it out to complete the excavation of the face, avoiding the huge smoke and dust generated by the blasting method, and at the same time allowing the removed part of the face to remain relatively intact, which is convenient for recycling.
[0024] The push rod 203 can adjust its angle by connecting to the rotating roller 202, so that it can be flexibly adjusted to extend into the gaps of the mesh palm face at different positions. The rotation adjustment of the rotating roller 202 is driven by the transmission wheel 2021, and the transmission wheel 2021 is driven by a motor.
[0025] Furthermore, the dragging assembly includes a displacement frame 204, a drill rod 2041, a driving device 2042, an electric telescopic rod 2043 and a lifting rod 2044. The displacement frame 204 is connected to the displacement slot 205. A lifting rod 2044 is provided at the middle bottom of the displacement frame 204. A driving device 2042 is provided at the top of the lifting rod 2044. One side of the driving device 2042 is connected to the drill rod 2041. One side of the bottom of the displacement frame 204 is connected to the electric telescopic rod 2043. The end of the electric telescopic rod 2043 away from the displacement frame 204 is connected to one side of the displacement slot 205. The lifting rod 2044 and the top rod 203 are both hydraulically telescopic.
[0026] After the split face is fractured and separated by the push rod 203, the push rod 203 is retracted, and the displacement frame 204 in the displacement slot 205 is moved by controlling the movement of the displacement frame 204, and the electric telescopic rod 2043 on one side is used to drive it to move, so that the drill rod 2041 on one side of the driving device 2042 in the middle of the displacement frame 204 will contact the split face. Then, through the rotation of the drill rod 2041 and the continuous movement of the displacement frame 204, it will drill into the split face, and then the drilled split face is pulled out by resetting the electric telescopic rod 2043, and then it is removed with the help of artificial tools. At the same time, the driving device 2042 is connected to the displacement frame 204 by the lifting rod 2044, so as to cooperate with the push rod 203 to remove the fracture of the split face at different positions, so as to facilitate the removal and recovery of the part that is located at a high position on the face and is inconvenient to remove.
[0027] The following is a specific implementation process of the present invention. First, when it is necessary to excavate the tunnel face, the tunnel face is cut into a mesh by a chain saw or other equipment. Then, by moving and lifting the movable base 201, the top rod 203 is tilted and extended into the gap between the cut meshes. Then, due to the hydraulic telescopic setting of the top rod 203, it is extended by hydraulic pressure. Because the tilting setting of the top rod 203, pressure is applied to the tunnel face cut out above, forcing this part of the tunnel face to bend upward, so that one end of the top rod 203 is broken, thereby completing the separation and removal of part of the tunnel face, and then taking it out to complete the excavation of the tunnel face, avoiding the huge smoke and dust generated by the blasting method, and at the same time allowing the removed part of the tunnel face to remain relatively intact, which is convenient for recycling. The top rod 203 can adjust its angle by connecting to the rotating roller 202, so that it can be flexibly adjusted to extend into the gap of the mesh tunnel face at different positions, and the rotating roller 202 The rotation adjustment is carried out by driving the transmission wheel 2021, which is driven by a motor. After the split face is fractured and separated by the push rod 203, the push rod 203 is retracted, and then the displacement frame 204 in the displacement slot 205 is moved by controlling the movement of the displacement frame 204, and the electric telescopic rod 2043 on one side is used to drive it to move, so that the drill rod 2041 on the side of the driving device 2042 in the middle of the displacement frame 204 will contact the fractured and separated split face, and then the drill rod 2041 is moved by the drill rod 2043. The rotation of 041 and the continuous movement of the displacement frame 204 allow it to drill into the split tunnel face, and then the drilled split tunnel face is pulled out by resetting the electric telescopic rod 2043, and then it is removed with the assistance of human tools. At the same time, the driving device 2042 is connected to the displacement frame 204 through the lifting rod 2044, so as to cooperate with the top rod 203 to remove the broken split tunnel faces at different positions, so as to facilitate the removal and recovery of the parts that are located high on the tunnel face and are inconvenient to remove.
[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
