[0043] With the improvement of tunneling technology, 3 - 5 tunnels are usually arranged at the existing working face, so higher requirements are imposed on the transfer of roadheaders. The existing conventional hard - rock tunnel roadheaders, whether open - type roadheaders or shield roadheaders, are basically used for the construction of a certain tunnel and cannot be transferred. When encountering the situation where transfer is needed, it is often to first disassemble the roadheader into modules, and then transport the disassembled parts of the equipment to the next working area through transportation tools such as heavy - duty transport vehicles and flatbed trucks, and then assemble and start again.

[0044] The present application provides a crawler - type roadheader to solve the problem of difficult transfer of roadheaders in the prior art. The following will further explain the present application with reference to the drawings.

[0045] Figure 1 is a schematic structural diagram of the crawler - type roadheader proposed by the present utility model; Figure 2 is a cross - sectional view of the crawler - type roadheader proposed by the present utility model; Figure 3 is Figure 2 a schematic structural diagram after removing the cutter head module and the main beam; Figure 4 is a top view of the chassis of the crawler - type roadheader proposed by the present utility model.

[0046] Combined with Figure 1 and Figure 2 As shown, the present application proposes a crawler - type roadheader, which includes a chassis 100 and a main beam 200 installed on the chassis 100. A main drive module 300, a cutter head module 400 and a support shoe propulsion module 500 are arranged on the main beam 200, and a muck conveyor module 600 and a traveling module 700 are also arranged on the chassis 100.

[0047] The main drive module 300 is connected to the cutter head module 400 and provides rotational power for the cutter head module 400, and the support shoe propulsion module 500 can drive the main beam 200 to move.

[0048] The traveling module 700 includes a driving assembly and two crawler wheels 710. The driving assembly is installed on the chassis 100, and the two crawler wheels 710 are respectively installed on opposite sides of the chassis 100. The driving assembly is used to drive the two crawler wheels 710 to rotate, so as to drive the crawler tunneling machine to move.

[0049] The muck conveying module 600 is at least partially located between the two crawler wheels 710. The muck conveying module 600 is used to receive and transport the muck generated by the cutter head module 400.

[0050] The direct transfer of the tunneling machine is realized through the traveling module 700 provided on the crawler tunneling machine, without the need to disassemble the tunneling machine and additionally set other auxiliary transfer devices, saving time and equipment investment, and meeting the requirements of rapid transfer and rapid relocation in multi-channel complex space tunnels.

[0051] Among them, the chassis 100 is located at the lower part of the crawler tunneling machine and is the framework of the tunneling machine, used to support all components on the tunneling machine.

[0052] The main beam 200 is installed on the chassis 100 and is used to support and move the cutter head module 400. The cutter head module 400 is arranged at the forefront of the tunneling machine and is used to break rock mass and soil. The support shoe propulsion module 500 includes a main drive cylinder and two support shoes. The two support shoes are respectively arranged at the rear positions on both sides of the main beam 200, preferably close to the center of gravity of the tunneling machine. When the tunneling machine is tunneling, the support shoes are supported on the tunnel walls on both sides, and the main drive cylinder provides power for the support shoes, used to provide the main thrust for the tunneling machine to move forward.

[0053] The muck conveying module 600 runs through the tunneling machine, transports the muck generated by the cutter head module 400 breaking the rock mass to the rear of the tunneling machine, and then transports it to the outside of the tunnel through a transport vehicle.

[0054] The traveling module 700 is mainly used for the backward movement, turning and forward movement of the tunneling machine. When the tunneling machine needs to be transferred, only need to control the traveling module 700 to move the tunneling machine to other tunnels.

[0056] Among them, the shield 800 is mainly located behind the cutter head module 400, surrounding the main drive module 300, and is used to protect the electronic components and circuits in the main drive module 300.

[0057] A protective cover 1100 is further provided above the chassis 100, used to protect other components of the tunneling machine, especially the electrical and hydraulic components.

[0058] In an embodiment of the present application, the cutter head module 400 includes a cutter head 410 and a slag receiving hopper 420. The upper opening of the slag receiving hopper 420 is at least partially located inside the cutter head 410, and the lower opening of the slag receiving hopper 420 is located above the muck conveying module 600. The slag receiving hopper 420 is used to collect the muck generated by the cutter head 410 and allow the muck to flow onto the muck conveying module 600.

[0059] Among them, the diameter of the cutter head 410 is 2.5 - 5 meters. The rock mass is damaged by rolling the disk cutters on the cutter head to roll and press the rock mass. The damaged rock mass passes through the gaps of the cutter head 410 and falls into the slag receiving hopper 420, so as to concentrate the muck on the muck conveying module 600 for transportation.

[0060] The slag receiving hopper 420 is funnel-shaped, and the lower opening is larger than the upper opening.

[0061] In an embodiment of the present application, the muck conveying module 600 includes a first conveyor belt assembly 610, a second conveyor belt assembly 620, and a third conveyor belt assembly 630 arranged in sequence from the cutter head module 400 to the chassis 100 direction. The first conveyor belt assembly 610 is connected to the main beam 200 and is located below the slag receiving hopper 420. The output end of the first conveyor belt assembly 610 is located above the second conveyor belt assembly 620, and the output end of the second conveyor belt assembly 620 is located above the third conveyor belt assembly 630.

[0062] As Figure 2 shown, the first conveyor belt assembly 610 is horizontally arranged on the main beam 200 and is shorter than the main beam 200. The lower end opening of the slag receiving hopper 420 is located directly above the first conveyor belt assembly 610. The second conveyor belt assembly 620 is inclined and arranged in the middle of the chassis 100. The front end is close to the ground, and the rear end extends backward and upward out of the tunneling machine. The third conveyor belt assembly 630 is arranged at the rear. The third conveyor belt assembly 630 is located below the second conveyor belt assembly 620. The rear part of the third conveyor belt assembly 630 completely extends out of the tunneling machine and is connected to a muck truck.

[0063] Combined with Figures 2 to 4 shown, in an embodiment of the present application, the muck conveying module 600 further includes a muck collection assembly 640. The muck collection assembly 640 is arranged at the input end of the second conveyor belt assembly 620. The muck collection assembly 640 is used to collect the muck that has fallen on the ground and transport it to the second conveyor belt assembly 620.

[0064] The muck collection assembly 640 is mainly used to shovel up the muck that has not fallen into the slag receiving hopper 420 on the ground and transport it to the second conveyor belt assembly 620.

[0065] In an embodiment of the present application, the muck collection assembly 640 includes a muck collection shovel 641 and at least one rotating wheel 642 disposed within the muck collection shovel 641. The rotating wheel 642 is used to drive the muck shoveled up by the muck collection shovel 641 to move.

[0066] Among them, the muck collection shovel 641 is fixed on the chassis 100. The rear end of the muck collection shovel 641 is connected to the second conveyor belt assembly 620. There are two rotating wheels 642 disposed on the muck collection shovel 641. The second conveyor belt assembly 620 is located between the two rotating wheels 642. The rotating directions of the two rotating wheels 642 are opposite. There are five fins disposed on the rotating wheel 642, and a baffle is disposed on each fin. The baffle drives the muck within the muck collection shovel 641 to gather towards the second conveyor belt assembly 620 by rotation.

[0067] In an embodiment of the present application, a plurality of rock bolt drilling modules 900 are further disposed on the chassis 100. The rock bolt drilling modules 900 are arranged radially along the tunnel cross-section. The rock bolt drilling modules 900 can perform rock bolt support on the tunnel.

[0068] Among them, the rock bolt drilling modules 900 are mainly disposed at the front end and the left and right sides of the chassis 100. The rock bolt drilling modules 900 adjust the angle by the rotation of the motor, thereby realizing the rock bolt support of the tunnel. The realization of the rock bolt support by the rock bolt drilling modules 900 belongs to the prior art, and the present utility model will not elaborate.

[0069] In an embodiment of the present application, at least four legs 110 are further disposed on the periphery of the chassis 100. The legs 110 are used to support the crawler tunneling machine.

[0070] Combined Figures 2 to 4 As shown, in an embodiment of the present application, a rotation module 1000 is further disposed on the chassis 100. The rotation module 1000 includes a mounting seat 1010 and two horizontal adjustment cylinders 1020. The main beam 200 is disposed on the mounting seat 1010. The mounting seat 1010 is mounted on the chassis 100 and is rotatably connected to the chassis 100. The axis direction of the mounting seat 1010 is perpendicular to the horizontal plane. Both of the two horizontal adjustment cylinders 1020 are mounted on the chassis. The piston rods of the two horizontal adjustment cylinders 1020 are both connected to the mounting seat 1010. The piston rods of the two horizontal adjustment cylinders 1020 are telescoped to drive the mounting seat 1010 to rotate, so that the main beam 200 rotates left and right.

[0071] The components of the rotation module 1000 are mainly disposed on the top of the chassis 100. The mounting seat 1010 can rotate to drive the main beam 200 on the mounting seat 1010 to rotate. The two horizontal adjustment cylinders 1020 mainly provide thrust for the rotation of the main beam 200.

[0072] In an embodiment of the present application, the rotation module 1000 further includes a vertical adjustment oil cylinder 1030. The main beam 200 is rotatably connected to the mounting seat 1010, and the axis direction of the main beam 200 is parallel to the horizontal plane. The vertical adjustment oil cylinder 1030 is disposed on the chassis 100, and the piston rod of the vertical adjustment oil cylinder 1030 is connected to the main beam 200. The main beam 200 is rotated up and down by the telescopic movement of the piston rod of the vertical adjustment oil cylinder 1030.

[0073] The vertical adjustment oil cylinder 1030 is inclinedly disposed on the mounting seat 1010, and the end of the main beam 200 is hinged to the mounting seat 1010, thereby driving the main beam 200 to rotate up and down.

[0074] The specific working steps and working principle of a tracked tunneling machine proposed by the present utility model will be further described:

[0075] 1. When tunneling, the main drive module 300 drives the cutter head 410 on the cutter head module 400 to rotate.

[0076] 2. The support shoe propulsion module 500 tightens against the tunnel wall, the tunneling machine advances forward, and the traveling module 700 also moves forward, while providing a forward propulsion force to the cutter head 410.

[0077] 3. The tunneling direction of the cutter head 410 is adjusted through the vertical adjustment oil cylinder 1030 and the horizontal adjustment oil cylinder 1020 in the rotation module 1000, and overexcavation can also be achieved. When the tunneling machine overexcavates in place, the tunneling machine does not need to advance, and the support shoe propulsion system does not need to tighten against the tunnel wall. At this time, the outriggers 110 need to be extended to support the entire main machine, providing a reaction force for the overexcavation action of the main machine to ensure that the tunneling machine does not move.

[0078] 4. For the muck generated by the tunneling of the cutter head module 400, a part of it is shoveled up by the scraper in the cutter head 410 and falls into the slag receiving hopper 420 inside the cutter head 410, and then the muck falls onto the first conveyor belt assembly 610 through the slag receiving hopper 420, and this part of the muck is transported to the second conveyor belt assembly 620 through the first conveyor belt assembly 610; for the other part of the muck generated by overexcavation that is not shoveled up by the scraper, it is collected by the rotating wheel 642 in the tunnel bottom muck collection assembly 640, and the muck is sent to the second conveyor belt assembly 620 by the rotation of the rotating wheel 642; finally, all the muck is transferred to the third conveyor belt assembly 630 through the second conveyor belt assembly 620, and then sent to the muck transport vehicle through the third conveyor belt assembly 630.

[0079] 5. After the main push oil cylinder completes a pushing stroke, the traveling module 700 stops advancing, the support shoes of the support shoe propulsion system are loosened, the main push oil cylinder retracts, driving the support shoes to move forward to complete the step-changing action.

[0080] 6. Repeating the above steps can complete the entire tunnel tunneling process.

[0081] 7. After completing a tunnel excavation, the traveling module 700 can drive the tunneling machine to retreat and transfer, realizing the rapid transfer of the multi-channel complex space tunnel. With the traveling module arranged at the bottom of the tunneling machine, the present utility model can move forward and backward, and the transfer is fast and convenient; the main beam can be rotated up, down, left and right through the rotating module to drive the turning of the cutter head module to realize the excavation of the tunnel; the muck collection component at the bottom of the tunnel can ensure the cleanliness of the tunnel bottom; the combination of multiple conveyor belt components can ensure the timely transfer of muck to the muck transport vehicle.
