[0021] Embodiment 1:

[0022] like Figure 1 As shown, the first embodiment provides a combined rock breaking method based on a mechanical cutting and projectile penetration combination device, the method is used to excavate a tunnel face, the combination device includes a rifled gun barrel, a loading part for providing shells for the rifled gun barrel and a power part for driving the shells to fire, a roller drill bit assembly, and a driving assembly for driving the roller drill bit assembly, a monitoring assembly and a control assembly, the control assembly is communicatively connected with the power part, the driving assembly and the monitoring assembly; the rifled gun barrel and the loading part are arranged on a frame; the combined rock breaking method includes:

[0023] The control component controls the monitoring component to obtain image information of the tunnel face; the control component controls the driving component to perform a driving action based on the image information; the control component controls the power unit to perform a firing action; wherein, when the control component controls the driving component to perform a driving action, it is used to drive the roller drill bit component to perform a primary crushing of the tunnel face; when the control component controls the power unit to perform a firing action, the power component is used to drive the shell from the loading unit into the rifled barrel for firing, so as to perform a secondary crushing of the tunnel face.

[0024] Specifically, the control component is used to control the face to obtain image information of the face, and then the control component controls the driving component according to the image information, so that the roller drill bit assembly performs a primary crushing on the face. Finally, the control component controls the power unit to perform a firing action, so that the shell enters the rifled barrel from the loading unit to be fired, so as to perform a secondary crushing on the face. Through this combined rock breaking method, the crushing of hard rock and extremely hard rock can be achieved.

[0025] In some possible implementations, for the step of the control component controlling the driving component to perform a driving action according to the image information, this embodiment 1 proposes an implementation, which includes: detecting whether the roller drill bit component is in contact with the face of the tunnel by the control component, and if so, controlling the driving component to perform a driving action, and if not, adjusting the distance between the roller drill bit component and the face of the tunnel, so that the roller drill bit component is in contact with the face of the tunnel, and then controlling the driving component to perform a driving action;

[0026] This is because the cone must be in direct contact with the tunnel face to destroy the tunnel face. If there is no direct contact or the contact is not sufficient, the construction will be in vain or the efficiency of rock breaking will be reduced.

[0027] In a possible implementation, the combined device includes a pressure sensing component, which is disposed on the roller drill bit assembly and is electrically connected to the control assembly. Based on the above components, for the step of detecting whether the roller drill bit assembly is in contact with the face through the control assembly, this embodiment 1 proposes an implementation, which includes: receiving a pressure value transmitted by the pressure sensor through the control assembly, and if the pressure value is greater than or equal to a preset pressure threshold, determining that the roller drill bit assembly is in contact with the face; if the pressure value is less than the preset pressure threshold, determining that the roller drill bit assembly is not in contact with the face;

[0028] In this way, it is possible to determine through pressure testing whether the roller drill bit is in full contact with the palm face, and then determine whether the conditions for opening the roller drill bit are met.

[0029] In some possible implementations, the combined device further includes a telescopic cylinder, a fixed end of which is disposed on a frame, a telescopic end of which is connected to a roller drill bit assembly, and the telescopic cylinder is electrically connected to a control assembly. Based on the above device, for the step of adjusting the distance between the roller drill bit assembly and the face, this embodiment proposes an implementation, which includes: the control assembly controls the telescopic end of the telescopic cylinder to perform a telescopic action to adjust the position of the roller drill bit assembly;

[0030] In this way, real-time adjustments can be made according to the distance between the drill bit and the palm face.

[0031] In some possible implementations, the combined device further includes a walking assembly, which is disposed at the bottom of the frame and is electrically connected to the control assembly. Based on the above device, for adjusting the distance between the roller drill bit assembly and the face, this embodiment 1 proposes an implementation, which includes: the control assembly controls the walking action of the walking assembly to adjust the position of the roller drill bit assembly;

[0032] When the roller drill bit is far away from the tunnel face and the telescopic cylinder in the first embodiment cannot be used to bring the roller drill bit into close contact with the tunnel face, the travel assembly can be used to adjust the distance between the roller drill bit and the tunnel face.

[0033] In some possible embodiments, the combination device also includes a power supply, which is connected to and supplies power to the driving component, the power unit, the control component, the pressure sensing component, the telescopic component and the walking component. Based on this, this embodiment 1 proposes an implementation method, in which the power of the driving component, the power unit, the pressure sensing component, the telescopic component and the walking device is monitored by the control component. If the power of any component among the driving component, the power unit, the pressure sensing component, the telescopic component and the walking component is lower than a preset power threshold, the component lower than the power threshold is determined to be a component to be charged, and the power supply is controlled to charge the component. When the power of the device is greater than or equal to the preset power threshold, the power supply is controlled to stop charging the component.

[0034] In some possible implementations, the combined device further includes an angle detection device, which is disposed on the roller drill bit assembly, and the angle detection device is also electrically connected to the control assembly. Based on this, before the control assembly controls the drive assembly to perform a driving action step according to the image information, this embodiment 1 proposes an implementation method, which further includes: controlling the angle calibration device to detect the angle between the roller drill bit assembly and the face through the control assembly, and if the angle is within a preset angle threshold range, the drive assembly can be controlled; if not, the angle between the roller drill bit assembly and the face is adjusted to be within the angle threshold range, and then the drive assembly is controlled;

[0035] The angle between the roller drill bit and the face is determined in this way. If there is a large deviation in the angle, effective face excavation cannot be carried out.

[0036] Furthermore, in some possible embodiments, the combined device also includes: an angle adjustment assembly is arranged between the three-roller drill bit assembly and the drive assembly, the angle adjustment assembly includes a universal joint assembly and a universal joint drive assembly for driving the universal joint assembly to rotate an angle, and the universal joint drive assembly is electrically connected to the control assembly. Based on this, for the adjustment of the angle between the roller drill bit assembly and the face to within the angle threshold range proposed in the above-mentioned embodiment one, this embodiment one proposes an implementation method, which includes: controlling the universal joint control assembly to rotate a preset angle through the control assembly to adjust the roller drill bit assembly to within the preset angle threshold range, so that the angle between the roller drill bit and the face can be adjusted in real time under the condition that the angle between the roller drill bit and the face does not match.

[0037] In some possible implementations, the combined device further includes: a mounting ring, a plurality of roller bit assemblies, the plurality of roller bit assemblies are arranged on the mounting ring, and the mounting ring is connected to the telescopic end of the telescopic oil cylinder. Based on the above device, before the control component controls the driving component to perform the driving action step according to the image information, this embodiment 1 proposes an implementation method, which includes: obtaining the area of ​​the face according to the image information of the face; setting the volume and shape of the mounting ring according to the area;

[0038] This is because the dimensions of the tunnel faces are different in different tunnel construction environments, so the shape and dimensions of the mounting ring must be determined based on the actual tunnel face area to achieve the purpose of corresponding matching.
