Description

Technical Field

[0001] The invention relates to the technical field of tunnel drilling, in particular to a dual-power tunnel boring machine. Background Art

[0002] In existing tunnel mining operations, most of them adopt the technology of blasting mining and slag excavation. Since the traditional mining and slag excavation technology has irreparable damage to the rock layer, mountain, vegetation, water source and other environments and huge safety hazards, it has been explicitly banned.

[0003] Currently, common tunnel boring machines use oil engines or electric motors as the sole driving force. Although the former is powerful, the diesel engine will produce smoke emissions when working, which causes serious pollution, causing air pollution in the tunnel and a harsh tunnel construction environment. Although the latter has no emissions or only has minimal emissions, and although it reduces the environmental pollution of tunnel construction, it has obviously insufficient power reserves under overload conditions, especially when encountering complex geological layers and high-hardness hard rock layers, it is even more insufficient when high-power drive is required.

[0004] During the drilling process, it is inconvenient to adjust the drilling position of the existing drilling machine, which is not conducive to drilling at any position of the tunnel. At the same time, the current drilling machines mostly adopt a vehicle body structure, which can move along the inside of the tunnel. However, a lot of gravel and soil will fall from the ground during the drilling process, which will affect the smoothness of the road and the progress of the device. Summary of the invention

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention can lift the vehicle body to a certain height through the transverse hydraulic cylinder on the mounting frame and the supporting hydraulic cylinder at the bottom of the vehicle body to maintain the stability of the drilling process. At the same time, the contact heads on both sides of the transverse hydraulic cylinder contact the inner walls on both sides of the tunnel to limit the vehicle body laterally to prevent the vehicle body from shifting.

[0018] 2. The present invention drives the first gear to rotate and mesh with the first tooth plate through the hydraulic motor of the crossbeam, thereby driving the crossbeam to slide laterally along the surface of the slide frame to adjust the lateral position of the drill bit. The thrust hydraulic cylinders on both sides of the crossbeam can push the mounting plate and the vertical beam to move longitudinally to adjust the longitudinal position of the drill bit. The vertical hydraulic cylinder drives the connecting seat to move up and down to adjust the vertical position of the drill bit, thereby facilitating the adjustment of the three-axis direction of the drill bit. The hydraulic motor on the back of the gear box drives the second gear to rotate and mesh with the second tooth plate, thereby realizing the forward and backward movement of the drive motor, gear box, drill barrel and drill bit, thereby realizing the feeding, drilling and exit of the drill barrel.

[0019] 3. The drill barrel assembly of the present invention is the main working part of the dual-power tunnel boring machine. The drill barrel connecting sleeve connects the drill barrel and the driving shaft of the driving gear box to transmit power. Together with the slag flushing water channel, the front end of the drill barrel is fixed with each working drill bit through a drill bit seat. The drill bit determines different drilling parameters according to the hardness of the working rock, including drill bit geometric dimensions, different drill barrel rotation speeds, different power values ​​of the adjustable motor, and the maximum pressure and flow of the slag flushing water, so as to obtain the best parameter configuration pair.

[0020] 4. The present invention connects the water inlet to a high-pressure water tank, and high-pressure water is sent out from the water outlet of the drill bit to discharge slag. The high-pressure water has a high pressure, which improves the slag discharge effect and reduces dust at the same time.

[0021] 5. In the present invention, before drilling, the guide assembly is stored at the front end of the vehicle body, because in the frame structure composed of the two groups of side panels and the film, the tops and bottoms of the two side panels are connected by spring telescopic rods, and the spring telescopic rods are structures with built-in springs in conventional telescopic rods. Therefore, the Harima can be folded to reduce the occupied area when not in use and avoid damage caused by collision. When in use, the long electric push rod pushes its slide plate to slide along the slide rail, and the guide assembly moves to the bottom of the drill bit. Then, according to the width of the tunnels on both sides, the two-way electric push rod drives the plug plate to pass through the inside of the connecting plate, and drives the side panel frames on both sides to rotate, so as to transport the fallen gravel to both sides as much as possible to avoid occupying the middle area. In this process and the process in which the lifting assembly drives the drill bit to move up and down, the bottom of the support column contacts the ground through the pulley, which is convenient for movement, and the slider slides along the slide groove to maintain the connectivity between the support column and the side panel, which has a certain supporting effect on the frame composed of the side panels.

[0022] 6. Compared with the prior art, the present invention can be used in complex environments through the crawler moving device at the bottom of the device. At the same time, the guide component transports the crushed stones and soil produced by drilling to both sides to avoid excessive accumulation on the middle road of the tunnel, thereby maintaining the smooth movement of the device. At the same time, the drilling component of the device can be adjusted on the X, Y, and Z axes under the cooperation of multiple devices, realizing the convenience of adjusting the drilling point.
