[0006] The track mechanism is laid on the bottom surface of the tunnel anchor hole, and one end of the track mechanism extends outside the tunnel anchor hole, and the other end of the track mechanism extends to the rear anchor chamber of the tunnel anchor hole;

[0007] The slag discharging device includes a slag discharging vehicle and a slag transporting mechanism arranged outside the tunnel anchor hole. The slag discharging vehicle is slidably connected to the track mechanism. The slag transporting mechanism includes a support frame and a driving component arranged on the support frame. The driving component is used to drive the slag discharging vehicle to displace along the length direction of the track mechanism;

[0008] The track mechanism includes a first track, a transition track, a second track and a third track laid in sequence. One end of the first track extends outside the tunnel anchor hole, and the other end of the first track is connected to the second track through the transition track.

[0009] Further, the included angle between the upper surface of the part of the first track located in the tunnel anchor hole and the horizontal plane is 20-30 degrees.

[0010] Further, the included angle between the upper surface of the second track and the horizontal plane is 40-55 degrees.

[0011] Further, the included angle between the upper surface of the third track and the horizontal plane is 35-50 degrees.

[0012] Furthermore, the driving assembly includes a winch, a bogie and a steering wheel, the bogie is mounted on a support frame and is rotatably connected to the steering wheel, and the steel strand of the winch is connected to the slag truck via the steering wheel.

[0013] Furthermore, a chute is provided on the support frame;

[0026] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] In the specific implementation manners provided in the present disclosure, a muck discharging system tooling for a large dip angle and small cross-section tunnel anchor in high plateau canyon mountainous areas is provided. Refer to Figure 1 and Figure 2As shown in the figure, the mucking system tooling for a large dip-angle and small cross-section tunnel anchor in a plateau canyon mountain area includes a track mechanism 1 and a mucking device. The track mechanism 1 is laid on the bottom surface of the tunnel anchor hole 5, and one end of the track mechanism 1 extends outside the tunnel anchor hole 5, while the other end of the track mechanism 1 extends to the rear anchor chamber 505 of the tunnel anchor hole 5. Among them, the track mechanism 1 includes a first track 101, a transition track 104, a second track 102, and a third track 103 laid in sequence. One end of the first track 101 extends outside the tunnel anchor hole 5, the other end of the first track 101 is connected to the second track 102 through the transition track 104, and a part of the third track 103 extends into the rear anchor chamber 505 of the tunnel anchor hole 5. The mucking device includes a mucking truck 2 and a slag transport mechanism 3 arranged outside the tunnel anchor hole 5. The mucking truck 2 is slidably connected to the track mechanism 1. The slag transport mechanism 3 includes a support frame 303 and a driving component 301 arranged on the support frame 303. The driving component 301 is used to drive the mucking truck 2 to displace along the length direction of the track mechanism 1.

[0028] Through the above technical solution, by laying the first track 101, the transition track 104, the second track 102, and the third track 103 in sequence on the bottom of the tunnel anchor hole 5, the mucking truck 2 can be displaced along the length direction of the track mechanism 1 under the driving action of the driving component 301, thus ensuring that the mucking truck 2 can still carry out mucking operations in an orderly manner even in the tunnel anchor hole 5 with a narrow space and a complex construction environment. At the same time, the transition track 104 arranged between the first track 101 and the second track 102 can enable the track mechanism 1 to better adapt to the tunnel anchor hole 5 with a large change in inclination angle, so that the mucking truck 2 can move smoothly and efficiently on the track, ensuring that the mucking operation can proceed smoothly and improving the mucking efficiency.

[0029] Exemplarily, when carrying out the construction operation of the tunnel anchor hole 5, the tunnel anchor hole 5 includes a main cable passing section 501, a saddle chamber section 502, a front anchor chamber 503, an anchor plug body 504, and a rear anchor chamber 505. Among them, the first track 101 is laid in the main cable passing section 501. The main cable passes through the main cable passing section 501 of the tunnel anchor hole 5 and extends to the area of the hoisting equipment or the hoisted object. The main function of the main cable passing section 501 is to guide the tension direction of the main cable. The saddle chamber section 502 is located between the main cable passing section 501 and the front anchor chamber 503. Among them, the transition track 104 is laid in the saddle chamber section 502, and equipment such as a cable saddle is installed in the saddle chamber section 502. The function of the front anchor chamber 503 is to fix the main cable through the anchor block and transfer the tension generated during the hoisting operation to a more stable foundation structure or soil. The second track 102 can be laid in the front anchor chamber 503. The anchor plug body 504 is usually located deep in the tunnel anchor hole 5, behind the front anchor chamber 503, and is the final fixing part of the main cable in the tunnel anchor hole 5. The third track 103 can be laid here and extend to the rear anchor chamber 505 of the tunnel anchor hole 5.

[0030] Exemplarily, referring to Figure 1 as shown, the included angle between the upper surface of a part of the first track 101 located in the tunnel anchor hole 5 and the horizontal plane is 20 - 30 degrees. Among them, the included angle between the upper surface of the first track 101 and the horizontal plane can be 25 degrees.

[0031] Exemplarily, referring to Figure 1 as shown, the included angle between the upper surface of the second track 102 and the horizontal plane is 40 - 55 degrees. Among them, the included angle between the upper surface of the second track 102 and the horizontal plane can be 47.8 degrees.

[0032] Exemplarily, referring to Figure 1 as shown, the included angle between the upper surface of the second track 102 and the horizontal plane is 40 - 55 degrees. Among them, the included angle between the upper surface of the second track 102 and the horizontal plane can be 43.6 degrees.

[0033] In some embodiments, referring to Figure 2 as shown, the driving assembly 301 includes a winch 3011, a bogie 3012 and a steering wheel 3013. Among them, the bogie 3012 is installed on the support frame 303 and rotatably connected with the steering wheel 3013. The steel wire rope 30111 of the winch 3011 is connected to the muck truck 2 through the steering wheel 3013. The steel wire rope 30111 connected to the winch 3011 can provide traction force for the muck truck 2, so that the muck truck 2 can move smoothly and efficiently on the track. And the steering wheel 3013 installed on the bogie 3012 can provide support for the steel wire rope 30111 and guide the extending direction of the steel wire rope 30111, avoiding the phenomenon of uneven tension or winding of the steel wire rope 30111, and ensuring the smooth operation of the muck truck 2.

[0034] At the same time, the winch 3011 can accurately control the forward and stop positions of the muck truck 2, avoiding the uncertainties existing in manual operation. Especially during the process of mucking in the tunnel anchor hole 5, by the way of using the winch 3011 to tow the muck truck 2, the dependence on manual operation can be reduced, the work efficiency can be improved, and human resources can be saved.

[0035] In some embodiments, referring to Figure 1 and Figure 2As shown, a chute 4 is provided on the support frame 303, and the chute 4 can provide a smooth and stable discharge channel for the slag transported by the slag discharge vehicle 2, ensuring that the slag transported to the outside of the tunnel anchor hole 5 can be orderly transported and processed later, that is, the chute 4 has a first end adjacent to an end of the first track 101 away from the transition track 104 and a second end away from the first track 101 and the first end is located above the second end, the first end has a feed port 401 for the slag to enter the chute 4, and the second end has a discharge port 402 for the slag to be discharged. Since the first end is located above the second end, under the action of gravity, the slag can be quickly discharged from the discharge port 402 after entering the chute 4. Therefore, tilting the chute 4 can effectively improve the slag discharge efficiency and avoid operation delays caused by slag accumulation or blockage.

[0036] In some embodiments, reference Figure 2 As shown, in order to ensure that the slag discharged from the discharge port 402 can be efficiently processed, the transportation equipment can be docked with the discharge port 402, that is, the slag transport mechanism 3 also includes a supporting platform 302, wherein the support frame 303 is arranged on the supporting platform 302 and the supporting platform 302 is provided with a unloading area 3021 corresponding to the second end.

[0037] Exemplarily, a transport device may be provided at the unloading area 3021, and the transport device includes but is not limited to a transport vehicle or a conveyor belt.
