[0049] A large-section soft rock roadway rapid tunneling construction process uses a large-section soft rock roadway rapid tunneling device as described above, and comprises the following steps:

[0050] Step one, in the tunneling process of the drill bit 4, the driving motor 512 is started at this time, the sliding block one 514 on the rotating rod 513 is driven to reciprocatingly swing one end of the reciprocating moving rod 511 through the driving motor 512, so that the sliding block two 516 drives the swing rod 518 to drive the rotating cylinder 519 to reciprocatingly rotate.

[0051] Step two, by rotating the fixed block 521 on the moving cylinder 515 left and right rotation, moving cylinder 515 in rotation to perpendicular to the support plate 520, at this time the extension spring 504 is extruded, when the fixed block 521 with moving cylinder 515 rotating to one side, at this time the moving cylinder 515 by the elastic force of the extension spring 504, so as to drive the moving impact rod 508 on the sliding round rod 507, through the impact head 509 on the drill bit 4 around the loose material to reciprocating impact.

[0053] Example two

[0054] In actual use, the operator found that when the device is used for tunneling in soft rock roadway, since the rock stratum is not regularly distributed, the device cannot adjust the speed of the drill bit 4 according to the actual hardness of the rock stratum, resulting in excessive wear or collapse of the drill bit 4 in use. At the same time, when the drill bit 4 is used for excavating the rock stratum, it will break the integrity of the rock stratum, causing large rocks to fall directly. Since the collecting hopper 601 is provided with a rotating collecting plate 602, when the rotating collecting plate 602 comes into contact with the large rocks, the large rocks will limit the rotation of the rotating collecting plate 602, causing the rotating collecting plate 602 to be damaged. At the same time, the rotating collecting plate 602 will also block the large rocks from entering the conveyor belt 603, which is not conducive to the collection and processing of the rocks. Moreover, the device cannot adjust the support force of the plug-in plate 706 on the roadway according to the actual stress of the roadway. Therefore, in order to solve the above technical problems, the device is improved according to the method described in this embodiment.

[0055] As shown in Figure 8 The middle part of the collecting hopper 601 is provided with a rotating groove 10, and the middle bottom end of the rotating groove 10 is provided with an electric push rod 9. The end of the electric push rod 9 away from the rotating groove 10 is provided with a limiting disc 8. The limiting disc 8 is rotatably connected with a rotating collecting plate 602. A plurality of elastic rods 11 are arranged in a ring array around the bottom of the limiting disc 8. The connection between the bottom of the elastic rod 11 and the rotating groove 10 is provided with a pressure sensor. The pressure sensor is used to detect the pressure value of each elastic rod 11.

[0056] The connecting part of the guide round rod 604 and the moving panel 605 is provided with a rotating assembly. The outer side of the moving panel 605 is provided with a rotating ring. The rotating ring is connected with a scraper 607 through a return spring 606 below. The rotating assembly is used to drive the rotating ring to slide on the moving panel 605. The sliding round rod 507 is provided with a displacement sensor. The displacement sensor is used to detect the displacement amount of the moving impact rod 508.

[0057] First, when the soft rock tunnel is excavated by the device, the sliding block one 514 on the rotating rod 513 is driven by the driving motor 512 to drive one end of the reciprocating moving rod 511 to reciprocate, so that the sliding block two 516 drives the swing rod 518 to drive the rotating cylinder 519 to reciprocate, the moving cylinder 515 on the fixed block 521 is driven to rotate left and right by the rotating cylinder 519, and the moving cylinder 515 is stretched when the rotating cylinder 519 is perpendicular to the support plate 520, at this time the stretching spring 504 is extruded, when the fixed block 521 drives the moving cylinder 515 to rotate to one side, at this time the moving cylinder 515 is driven by the elastic force of the stretching spring 504, so that the moving impact rod 508 moves on the sliding cylinder 507, and the surrounding loose material around the drill bit 4 is reciprocally impacted by the impact head 509. In this process, the displacement sensor arranged on the sliding cylinder 507 is used to detect the displacement of the moving impact rod 508 in real time. Since the rotation frequency and speed of the driving motor 512 are constant, the displacement of the moving impact rod 508 is also constant. If the displacement of the moving impact rod 508 is detected to be less than the preset range within a certain period of time, it is determined that the rock layer at this position is hard, and the moving impact rod 508 cannot drive the impact head 509 to pierce the rock, so that the moving impact rod 508 cannot continue to move forward. Similarly, if the displacement of the moving impact rod 508 is detected to be greater than the preset range within a certain period of time, it is determined that the rock layer at this position is soft, and the moving impact rod 508 drives the impact head 509 to pierce the rock, so that the moving amount of the moving impact rod 508 increases. At this time, the moving amount of the moving impact rod 508 is detected to detect the hardness of the rock layer at this position, and the rotation speed of the drill bit 4 is adjusted according to the hardness of the rock layer, which further improves the excavation efficiency of the device, and effectively prevents the problem that the rotation speed of the drill bit 4 cannot be adjusted according to the actual hardness of the rock layer, so that the drill bit 4 is excessively worn or damaged during use.

[0058] Meanwhile, the hardness of the rock layer is detected according to the displacement of the moving impact rod 508 detected by the displacement sensor, and the rotation rate of the rotating collecting plate 602 is adjusted in real time according to the hardness of the rock layer, so as to prevent the problem that the rotating collecting plate 602 is damaged due to too fast rotation speed when collecting hard rock.

[0059] And the stones collected on the conveying belt 603 by the rotating collecting plate 602 are laid flat by the reciprocating rotation of the adjusting motor 610 and the rotating assembly to drive the scraper 607 to swing above the conveying belt 603, and the stones blocked between the rotating collecting plate 602 and the conveying belt 603 are effectively dispersed by the forward and backward swinging of the scraper 607 driven by the rotating assembly, preventing the problem that the stones are blocked in the inlet and cannot be effectively collected.

[0060] Secondly, when the displacement sensor detects that the displacement of the moving impact rod 508 reaches the maximum preset range, it is determined that the rock in the area where the drill bit 4 is located falls in advance during the excavation process of the drill bit 4. In this process, the drill bit 4 is controlled to move up, down, left and right, and the moving impact rod 508 is used to impact the area to obtain the size of the falling rock, and the electric push rod 9 is controlled to be in a free extension state. When the rock moves to the collecting hopper 601, the rotating collecting plate 602 is pushed to move into the rotating groove 10, and the elastic rod 11 arranged around the limiting disc 8 is extruded, thereby realizing the displacement of the falling rock and effectively preventing the problem that the volume of the falling rock is too large, causing the rotating collecting plate 602 to contact the rock and be damaged.

[0061] At the same time, when the rotating collecting plate 602 moves into the rotating groove 10, the device continuously advances to push the large rock to move in the direction of the conveyor belt 603. In this process, the large rock will completely move to the top of the rotating collecting plate 602. At this time, the rotating collecting plate 602 is controlled to rotate to push the large rock to rotate in the direction of the conveyor belt 603. At the same time, the rotating assembly drives the scraper 607 to move back and forth. In this process, the pressure value detected by the pressure sensor arranged on the elastic rod 11 is used to judge the size of the rock, and the rotating speed of the rotating assembly is adjusted according to the size of the rock and the hardness of the rock detected by the moving impact rod 508, so that the scraper 607 follows the rotation of the rotating assembly and collides with the rock under the action of the return spring 606, thereby crushing the large rock to prevent the large rock from entering the conveyor belt 603 and causing problems in the collection and processing of the rock.

[0062] Finally, during the excavation process of the drill bit 4, if the moving impact rod 508 detects that a large rock has fallen, the device moves forward to collect the large rock into the collecting hopper 601. The electric push rod 9 arranged at the bottom of the rotating collecting plate 602 is controlled to be in a free extension state. When the large rock moves to the contact position of the rotating collecting plate 602 and moves in the direction of the conveyor belt 603, the large rock will extrude the rotating collecting plate 602. In this process, the elastic rod 11 arranged at the bottom of the rotating collecting plate 602 buffers the extrusion force of the rock, and the pressure sensor arranged on the elastic rod 11 detects the position of the falling rock in real time. If the pressure value of the left pressure sensor is greater than that of the right pressure sensor at this time, it is determined that the falling rock is located on the left side of the roadway, and the overall support force on the left side of the roadway will be weakened. Subsequently, the support two 705 on the opposite side is controlled to be elongated to enhance the support force on one side of the roadway, thereby avoiding the problem of collapse of the roadway during the excavation process.

[0063] It needs to be specially pointed out that the present application detects the displacement of the moving impact rod 508 in real time by setting the displacement sensor on the sliding round rod 507, analyzes the hardness of the rock stratum to be excavated according to the displacement detected by the displacement sensor, adjusts the rotating speed of the drill bit 4 and the rotating collecting plate 602 according to the different rock stratum hardness, detects the rock falling condition through the displacement, adjusts the movement state of the rotating collecting plate 602 correspondingly, detects the position of the falling rock, cooperates with the protection assembly 7 to effectively support the roadway, and effectively crushes the falling rock through the movement of the rotating collecting plate 602 cooperating with the scraper 607.

[0064] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
