[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0048] Existing cantilevered tunnel boring machines primarily consist of a cutting mechanism, a loading mechanism, a transport mechanism, a traveling mechanism, and a hydraulic system. The cutting mechanism typically includes a cutting head equipped with pick-shaped teeth. During tunneling, the rotating cutting head uses its pick-shaped teeth to cut the tunnel face. The cut rock and soil are then transported to the designated location via the loading and transport mechanisms. However, these cantilevered tunnel boring machines not only suffer from low cutting efficiency, but also suffer from the high cost of frequent replacement of the pick-shaped teeth on the cutting head due to wear.

[0049] In view of this, the present invention provides a roller cutter type rock tunnel boring machine, including a body, a traveling mechanism, a cutting device, a transport mechanism and a loading mechanism. The traveling mechanism is arranged on the body to drive the body to move forward through the traveling mechanism; the cutting device includes a mounting seat, a drive unit and a cutter disc, the mounting seat is movably connected to the front end of the body, the drive unit is arranged on the mounting seat, the cutter disc is transmission-connected to the drive unit to drive the cutter disc to rotate through the drive unit, and a plurality of roller cutters for cutting rock and soil are arranged on the periphery of the cutter disc; the transport mechanism is arranged on the body, the loading mechanism is arranged at the front end of the transport mechanism, and the loading mechanism is located below the cutting device, the loading mechanism is configured to transport the rock and soil cut by the cutting device to the transport mechanism, and the transport mechanism is configured to transport the rock and soil to the rear of the tunnel boring machine. During tunneling, the drive unit of the cutting device rotates the cutterhead, which crushes the rock wall with its roller cutters, thereby cutting the rock wall. Simultaneously, the movably connected mounting base swings to move the cutterhead, thereby cutting at different locations on the rock wall. The roller cutter-type rock tunneling machine provided by the present invention utilizes a roller cutter structure, resulting in a larger rock breaking area and higher cutting efficiency. The roller cutter structure also exhibits excellent wear resistance, resulting in a longer service life and lower costs.

[0051] You can refer to Figures 1 to 9The embodiment of the present invention provides a roller cutter rock boring machine 100, including a vehicle body, a traveling mechanism 130, a cutting device 140, a material transporting mechanism 160 and a loading mechanism 150. The traveling mechanism 130 is arranged on the vehicle body to drive the vehicle body to move forward through the traveling mechanism 130; the cutting device 140 includes a mounting seat 141, a driving unit 142 and a cutter head 143. The mounting seat 141 is movably connected to the front end of the vehicle body, the driving unit 142 is arranged on the mounting seat 141, and the cutter head 143 is transmission-connected to the driving unit Element 142 drives the cutter disc 143 to rotate through the driving unit 142, and a plurality of rollers 144 for cutting rock and soil are arranged on the periphery of the cutter disc 143; the transport mechanism 160 is arranged on the vehicle body, and the loading mechanism 150 is arranged at the front end of the transport mechanism 160, and the loading mechanism 150 is located below the cutting device 140, and the loading mechanism 150 is configured to transport the rock and soil cut by the cutting device 140 to the transport mechanism 160, and the transport mechanism 160 is configured to transport the rock and soil to the rear of the tunnel boring machine 100.

[0052] The cutting device 140 in the roller cutter rock boring machine 100 provided in an embodiment of the present invention includes a mounting base 141, a drive unit 142, and a cutterhead 143. The mounting base 141 is movably connected to the front end of the vehicle body, the drive unit 142 is arranged on the mounting base 141, and the cutterhead 143 is transmission-connected to the drive unit 142. When the cutting device 140 is excavating a tunnel, the drive unit 142 can drive the cutterhead 143 to rotate, and the cutterhead 143 uses the roller cutters 144 thereon to squeeze and crush the rock wall, thereby cutting the rock wall. At the same time, the movably connected mounting base 141 can drive the cutterhead 143 to move together by swinging, thereby cutting different positions of the rock wall. The roller cutter 144 structure used in the roller cutter rock boring machine 100 provided in an embodiment of the present invention has a larger rock breaking area and higher cutting efficiency. The roller cutter 144 structure has good wear resistance, resulting in a longer service life and lower cost.

[0053] like Figure 1 and Figure 2As shown, in the above embodiment, the vehicle body may include a front body 110 and a rear body 120, with the rear body 120 movably connected to the rear end of the front body 110. Both the front body 110 and the rear body 120 are equipped with a running mechanism 130. The front and rear bodies 120 are movably connected, and each is equipped with a running mechanism 130. The running mechanism 130 can independently control the movement of the front body 110 or the rear body 120, allowing the roadheader 100 to make turns with a smaller radius and more maneuverable. The use of the front and rear running mechanisms 130 can increase the load capacity of the roadheader 100 and provide a more stable excavation structure. Specifically, the running mechanism 130 can be a crawler-type structure, with crawler chassis installed on both sides of the front body 110 and the rear body 120, forming a bilaterally symmetrical arrangement. Each crawler chassis can be independently controlled as needed. The differential drive of the crawlers on both sides can control the direction of travel of the front body 110 and the rear body 120, further enhancing the maneuverability of the roadheader 100.

[0054] In the above embodiment, the front vehicle body 110 may include an adjusting mechanism 111, the adjusting mechanism 111 includes a connecting seat 1111, a connecting frame 1112 and a driving cylinder 1113, the connecting seat 1111 is connected to the mounting seat 141, the front end of the connecting frame 1112 is movably connected to the connecting seat 1111, the driving cylinder 1113 is connected between the connecting frame 1112 and the connecting seat 1111, and there may be multiple driving cylinders 1113. Different driving cylinders 1113 can drive the connecting seat 1111 to swing in different directions through telescoping, thereby driving the cutter head 143 on the cutting device 140 to swing in different directions, thereby realizing flexible excavation of the tunnel rock wall.

[0055] In the above embodiment, the front vehicle body 110 may further include a supporting device 112, the supporting device 112 includes a first telescopic cylinder 1121, an upper supporting unit 1122 and a lower supporting unit 1123, the first telescopic cylinder 1121 is connected between the front end of the supporting device 112 and the rear end of the connecting frame 1112, so as to drive the connecting frame 1112 forward or backward through the telescopic cylinder, thereby driving the cutting device 140 to move forward or backward; the upper supporting unit 1122 is used to support on the top wall of the tunnel, and the lower supporting unit 1123 is used to support on the ground. It can be understood that when the first telescopic cylinder 1121 extends, the first telescopic cylinder 1121 drives the connecting frame 1112 and the cutting device 140 connected to the connecting frame 1112 to move forward, thereby causing the cutter disc 143 to advance toward the tunnel face and squeeze the rock wall, completing the feed action; when the first telescopic cylinder 1121 retracts, the first telescopic cylinder 1121 drives the connecting frame 1112 and the cutting device 140 to move backward, thereby causing the cutter disc 143 to separate from the tunnel face, completing the retraction action. Among them, the upper support unit 1122 and the lower support unit 1123 can be evenly arranged on the left and right sides of the front body 110. When the cutting device 140 in front performs excavation operations, the upper support unit 1122 and the lower support unit 1123 can be supported on the top and bottom of the tunnel respectively, providing support and fixation for the entire machine, so that the body can withstand a stronger reverse impact force during rock breaking, avoiding problems such as overturning, slipping, and sliding of the tunnel boring machine 100 due to vibration of the body, enhancing the stability of the fuselage, and improving construction safety.

[0056] The above embodiment may further include a connecting assembly 170, which includes a first hinge seat 171 and a second hinge seat 172. The first hinge seat 171 is disposed at the rear end of the support device 112, and the second hinge seat 172 is disposed at the front end of the rear body 120. The first hinge seat 171 and the second hinge seat 172 are hinged together. The first hinge seat 171 and the second hinge seat 172 can be used to flexibly connect the front body 110 and the rear body 120, and facilitate connection and disconnection of the two when necessary.

[0057] In the above embodiment, the connecting assembly 170 may further include a second telescopic cylinder 173 connected between the first hinge seat 171 and the second hinge, so as to drive the front body 110 and the rear body 120 to swing relative to each other in the left and right directions via the second telescopic cylinder 173. Specifically, two second telescopic cylinders 173 may be provided, symmetrically disposed on either side of the first hinge seat 171 and the second hinge seat 172. By varying the telescopic lengths of the two second telescopic cylinders 173, the front body 110 and the rear body 120 can be swung left and right and fixed in position. For example, when the roadheader 100 is turning, the telescopic lengths of the two second telescopic cylinders 173 can be adjusted so that the angle between the front and rear bodies 120 is aligned with the curvature of the curve, thereby enabling the roadheader 100 to turn smoothly.

[0058] In the above embodiment, the first end of the second articulated seat 172 can be articulated to the rear body 120. The connecting assembly 170 further includes a third telescopic cylinder 174 connected between the second end of the second articulated seat 172 and the rear body 120. The third telescopic cylinder 174 drives the rear body 120 and the front body 110 to swing vertically relative to each other via the third telescopic cylinder 174, thereby facilitating the tunnel boring machine 100 to navigate uneven roads. Specifically, for example, when the tunnel boring machine 100 encounters a pothole, the length of the third telescopic cylinder 174 can be adjusted to apply a certain upward lifting force to the front body 110 as the front body 110 enters the pothole, thereby reducing the pressure of the front body 110 on the pothole bottom and preventing the front body 110 from sinking too deeply into the pothole, thereby facilitating the front body 110 to navigate the pothole. Similarly, the conditions for the rear body 120 to navigate the pothole are similar to those for the front body 110 and will not be further described.

[0059] In the above embodiment, the axial direction of the cutterhead 143 can be aligned with the width direction of the roadheader 100, wherein the width direction of the roadheader 100 is perpendicular to the front-to-back direction of the roadheader 100. In this way, when the cutterhead 143 rotates, the rollers 144 on the cutterhead 143 can perform a scraping-type cutting operation from top to bottom, utilizing the weight of the cutterhead 143 to a certain extent for cutting, thereby improving the cutting force and efficiency.

[0060] In the above embodiment, a dust removal device 180 may also be included. The dust removal device 180 is arranged on the front vehicle body 110. The dust removal device 180 is used for dust removal. Specifically, the dust removal device 180 can be installed on both sides of the rear end of the support device 112. The dust removal device 180 absorbs the dust particles generated during the excavation process. On the one hand, it can effectively improve the working environment of the construction workers and protect the health of the construction workers. On the other hand, it can reduce the dust entering the interior of the tunnel boring machine 100 and reduce the failure rate of the tunnel boring machine 100.

[0061] The above embodiment may also include a support device 190, which is mounted on the front body 110 and is used to support the inner wall of the tunnel. The support devices 190 can be installed on both sides of the rear end of the support device 112 and are symmetrically distributed. This allows for synchronous support during excavation, improving excavation efficiency and construction safety while reducing the intensity of manual support.

[0063] The cutting device 140 in the roller cutter rock boring machine 100 provided in an embodiment of the present invention includes a mounting base 141, a drive unit 142, and a cutterhead 143. The mounting base 141 is movably connected to the front end of the vehicle body, the drive unit 142 is arranged on the mounting base 141, and the cutterhead 143 is transmission-connected to the drive unit 142. When the cutting device 140 is excavating a tunnel, the drive unit 142 can drive the cutterhead 143 to rotate, and the cutterhead 143 uses the roller cutters 144 thereon to squeeze and crush the rock wall, thereby cutting the rock wall.
