[0030] like Figure 2-7 As shown, the first aspect of the embodiment of the present disclosure provides an auxiliary continuous climbing device 10 for a large-slope tunnel boring machine, which is used to assist the tunnel boring machine in climbing a slope in a tunnel; the auxiliary continuous climbing device 10 includes a base plate 11, a first telescopic cylinder 24, a first sliding shoe 23 and a driving mechanism.

[0031] The bottom plate 11 is used for being fixedly connected to the tunnel boring machine.

[0032] The first telescopic cylinder 24 is horizontally mounted on the base plate 11 and is movable relative to the base plate 11 .

[0033] The first sliding shoe 23 is hingedly disposed at the movable end of the first telescopic oil cylinder 24 and is used for abutting and fixing against the side wall of the tunnel.

[0034] The driving mechanism is connected between the base plate 11 and the first telescopic cylinder 24, and is used to enable relative movement between the base plate 11 and the first telescopic cylinder 24; when the first telescopic cylinder 24 is extended and the first sliding shoe 23 is abutted and fixed against the side wall of the tunnel, the driving mechanism drives the base plate 11 to generate relative movement relative to the first telescopic cylinder 24, thereby driving the tunnel boring machine to move.

[0035] The fixed connection between the fixed bottom plate 11 and the tunnel boring machine and the mobility of the first telescopic oil cylinder 24 realize the dynamic fixation between the tunnel boring machine and the side wall of the tunnel. This design enables the tunnel boring machine to obtain additional support and traction during the climbing process, thereby improving the climbing ability and stability of the tunnel boring machine under large slope conditions; thereby improving the climbing efficiency and safety of the tunnel boring machine under large slope conditions, and reducing equipment failures and safety accidents caused by large slopes.

[0036] As an optional embodiment, the driving mechanism includes a motor member 14, a gear 15 and a first rack 22; the motor member 14 is fixed to the base plate 11 through the motor seat 13, and the gear 15 is fixed to the output shaft of the motor member 14; the first rack 22 is slidably mounted on the base plate 11 and is fixedly connected to the first telescopic cylinder 24; the first rack 22 is meshed with the gear 15 for transmission. The combination of the motor member 14, the gear 15 and the first rack 22 in the driving mechanism provides a power transmission mechanism, so that the base plate 11 can produce relative movement relative to the first telescopic cylinder 24. This design enhances the traction of the tunnel boring machine through power transmission, enabling it to move more effectively in tunnels with larger slopes; thereby improving the traction and movement efficiency of the tunnel boring machine under large slope conditions and reducing climbing failures caused by insufficient power.

[0037] It should be noted that, in other embodiments, the driving mechanism can also use a hydraulic cylinder to enable the bottom plate 11 to generate relative movement relative to the first telescopic cylinder 24. The present disclosure is not limited to this.

[0038] As an optional embodiment, the auxiliary continuous climbing device 10 also includes a second telescopic oil cylinder 27 and a second sliding shoe; the second telescopic oil cylinder 27 is horizontally installed on the bottom plate 11 and can move relative to the bottom plate 11; the second sliding shoe is hingedly arranged at the movable end of the second telescopic oil cylinder 27, and is used to abut and fix with the side wall of the tunnel; wherein the second telescopic oil cylinder 27 and the first telescopic oil cylinder 24 alternately drive the second sliding shoe and the first sliding shoe 23 to be fixed with the side wall of the tunnel. The addition of the second telescopic oil cylinder 27 and the second sliding shoe forms an alternating working mechanism with the first telescopic oil cylinder 24 and the first sliding shoe 23, so that the tunnel boring machine always has a sliding shoe fixed on the side wall of the tunnel during the climbing process, providing continuous support and traction; this enhances the stability and continuity of the tunnel boring machine during the climbing process, and reduces equipment sliding or accidents caused by the failure of a single fixed point.

[0039] As an optional embodiment, a pick tooth structure is provided on the first sliding shoe 23 to enhance the fixing effect between the first sliding shoe 23 and the side wall of the tunnel, and a pick tooth structure is provided on the second sliding shoe to enhance the fixing effect between the second sliding shoe and the side wall of the tunnel.

[0040] As an optional embodiment, the driving mechanism also includes a second rack 28, which is slidably mounted on the base plate 11 and fixedly connected to the second telescopic cylinder 27, and the second rack 28 is meshed with the gear 15 for transmission; the addition of the second rack 28, which is fixedly connected to the second telescopic cylinder 27 and meshed with the gear 15 for transmission, enables the second telescopic cylinder 27 to work more effectively with the gear 15, thereby improving the efficiency and reliability of power transmission; improving the power transmission efficiency and reliability of the tunnel boring machine under large slope conditions, and reducing the occurrence of climbing failure due to power transmission failure.

[0041] As an optional embodiment, the second rack 28 is arranged in parallel with the first rack 22. This arrangement helps to maintain the synchronous operation of the two telescopic cylinders, thereby improving the coordination and efficiency of the entire climbing device.

[0042] As an optional embodiment, when the motor member 14 rotates forward, one of the first and second sliding shoes 23 is fixed to the side wall of the tunnel, and when the motor member 14 rotates reversely, the other of the first and second sliding shoes 23 is fixed to the side wall of the tunnel. The forward and reverse rotation control of the motor member 14 enables the first and second sliding shoes 23 to be alternately fixed to the side wall of the tunnel. This design allows the tunnel boring machine to dynamically adjust the support point during the climbing process, always keeping at least one sliding shoe fixed to the side wall of the tunnel, providing continuous support and traction; this improves the climbing stability and continuity of the tunnel boring machine under large slope conditions, and reduces equipment sliding or accidents caused by power interruption or support point failure.

[0043] As an optional embodiment, the auxiliary continuous climbing device 10 further includes a first rotary cylinder 25 and a second rotary cylinder 29 mounted on the base plate 11; the first rotary cylinder 25 is connected to the first telescopic cylinder 24 to drive the first telescopic cylinder 24 to rotate horizontally; the second rotary cylinder 29 is connected to the second telescopic cylinder 27 to drive the second telescopic cylinder 27 to rotate horizontally. The first rotary cylinder 25 and the second rotary cylinder 29 included in the auxiliary continuous climbing device 10 are respectively connected to the first telescopic cylinder 24 and the second telescopic cylinder 27, so that the telescopic cylinders can rotate horizontally. This design allows the telescopic cylinders and the sliding shoes to be folded and stored on the base plate 11 when the tunnel boring machine does not need climbing assistance, reducing the occupied space and facilitating the movement and operation of the tunnel boring machine in a straight tunnel; the auxiliary climbing device can be compactly folded when not in use, so that no additional width or obstacles are added when the tunnel boring machine passes through a narrow or straight tunnel, thereby improving the flexibility and passability of the tunnel boring machine. At the same time, this design is also convenient for maintenance and overhaul, because the telescopic oil cylinder and the sliding shoe can be easily turned to a position convenient for maintenance. Specifically, the first rotary oil cylinder 25 is provided with a first flange 26, and the cylinder barrel of the first telescopic oil cylinder 24 is fixedly connected to the first rotary oil cylinder 25 through the first flange 26; the second rotary oil cylinder 29 is provided with a second flange, and the cylinder barrel of the second telescopic oil cylinder 27 is fixedly connected to the second rotary oil cylinder 29 through the second flange.

[0044] As an optional embodiment, the auxiliary continuous climbing device 10 further includes a first sliding plate 21 and a second sliding plate slidably mounted on the bottom plate 11; the first sliding plate 21 and the second sliding plate are respectively fixedly connected to the first rack 22 and the second rack 28. The sliding installation of the first sliding plate 21 and the second sliding plate are fixedly connected to the first rack 22 and the second rack 28, and this design simplifies the structure and improves the stability and durability of the device.

[0045] As an optional embodiment, the auxiliary continuous climbing device 10 also includes a first pressure plate 12 and a second pressure plate; the first pressure plate 12 is fixedly mounted on the base plate 11, and cooperates with the base plate 11 to form a sliding groove for the first sliding plate 21 to slide; the second pressure plate is fixedly mounted on the base plate 11, and cooperates with the base plate 11 to form a sliding groove for the second sliding plate to slide, thereby forming a stable sliding environment for the first sliding plate 21 and the second sliding plate.

[0046] like Figure 1As shown, the second aspect of the embodiment of the present disclosure provides a tunnel boring machine, which includes an auxiliary continuous climbing device 10 for a tunnel boring machine with a large slope as described above. The tunnel boring machine includes a tunnel boring machine body 1 and two auxiliary continuous climbing devices 10 for a tunnel boring machine with a large slope; the two auxiliary continuous climbing devices 10 for a tunnel boring machine with a large slope are respectively fixedly installed on the left and right sides of the tunnel boring machine body 1. The tunnel boring machine is equipped with two auxiliary continuous climbing devices 10, which are respectively fixedly installed on the left and right sides of the tunnel boring machine body 1. This symmetrical layout improves the balance and stability of the tunnel boring machine during the climbing process, and ensures the efficient operation of the tunnel boring machine in complex terrain.

[0047] The working process of the tunnel boring machine is as follows:

[0048] like Figure 5 and Figure 6 As shown, the first telescopic cylinder 24 and the second telescopic cylinder 27 are perpendicular to the bottom plate 11 by rotating the first rotary cylinder 25 and the second rotary cylinder 29 by 90 degrees respectively. At this time, the bottom of the first flange 26 is in contact and locked with the first sliding plate 21, and the bottom of the second flange is in contact and locked with the second sliding plate. Then the first telescopic cylinder 24 located at the front end of the tunnel boring machine is unfolded, so that the first sliding shoe 23 is pressed against the side wall of the tunnel to play a fixing role, and then the motor is started to drive the gear to rotate, the gear and the first rack are meshed to generate relative movement between the first telescopic cylinder 24 and the bottom plate 11, and the gear and the second rack are meshed to generate relative movement between the second telescopic cylinder 27 and the bottom plate 11. Since the first telescopic cylinder 24 is fixed to the side wall of the tunnel through the first sliding shoe 23, the relative movement is equivalent to providing power to the bottom plate 11, thereby providing power for the tunnel boring machine to move forward.

[0049] When the mobile device moves to Figure 7 The second telescopic oil cylinder 27 at the rear end is deployed, so that the second sliding shoe is pressed against the side wall of the tunnel to fix it, and then the first telescopic oil cylinder 24 is retracted, and the first sliding shoe 23 is separated from the side wall of the tunnel. During this process, the auxiliary continuous climbing device of the large-slope tunnel boring machine is always in contact with the coal wall and fixed, which plays an anti-skid role. Then the motor is started to reverse and drive the gear to rotate. The gear and the second rack are engaged to drive the relative movement between the second telescopic oil cylinder 27 and the bottom plate 11. Since the second telescopic oil cylinder 27 is fixed to the side wall of the tunnel through the second sliding shoe, the relative movement is equivalent to providing power to the bottom plate 11, thereby providing power to the tunnel boring machine to move forward.

[0050] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
