[0092] A power tunnel is a fully enclosed underground structure that accommodates power transmission cables and has inspection channels. There are two main methods for constructing power tunnels: shield tunneling and shallow-buried dark excavation. The shield tunneling method uses a rotary cutter to break up the surrounding rock in the tunnel to form the entire tunnel section. However, due to its poor flexibility, its scope of use is limited. When faced with power tunnel construction with a large curvature, the shallow-buried dark excavation method must be used for construction.

[0093] In the relevant technology, workers use steel shovels to dig and bag the slag; after cleaning and forming the entire tunnel section, an arch frame is set up to support the tunnel wall, and the arch frame is carried by the staff; finally, the workers use handheld nozzles to spray and reinforce the tunnel wall, thereby completing the construction of the power tunnel.

[0094] However, the above steps are all completed manually, which makes the efficiency of tunnel construction low.

[0095] Based on this, the present application provides a tunnel excavation equipment, including a frame, a traveling mechanism, an excavation arm and an operating arm, wherein the excavation arm includes a connecting arm assembly and a bucket, and the operating arm includes a cantilever assembly, a rotating assembly and a clamping assembly.

[0096] When the shallow buried tunneling method is used for tunnel construction, the traveling mechanism drives the frame to move as a whole to the tunnel to be excavated. At the same time, the connecting arm assembly arranged on one side of the frame drives the bucket to be lifted or lowered relative to the frame to excavate and preliminarily shape the circumferential side of the tunnel. After the general outline of the tunnel is completed, the staff will select the corresponding auxiliary operating mechanism to be installed on the clamping end of the clamping assembly according to the progress of the subsequent excavation operation. The cantilever assembly and the rotating assembly arranged on the other side of the frame drive the clamping assembly to move or rotate relative to the frame, thereby driving the auxiliary operating mechanism to move or rotate relative to the frame to drill, erect arches and spray-mix reinforce the tunnel to complete the tunnel excavation operation.

[0097] Therefore, the present application replaces the manual operation link of tunnel construction using shallow buried dark excavation method in the prior art through the mutual cooperation between the digging arm and the operating arm, which not only reduces the safety risk of tunnel construction, but also realizes the automated excavation of the tunnel and improves the efficiency of tunnel excavation.

[0098] The technical solution of the present application is described in detail below with reference to the accompanying drawings using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0099] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a tunnel excavation device, including a frame 100, a traveling mechanism 200, an excavation arm 300 and an operating arm 400; the traveling mechanism 200 is arranged at the bottom of the frame 100 to support and drive the frame 100 to move.

[0100] It should be noted that in the present application, there is no restriction on the specific structure of the traveling mechanism 200, as long as it supports and drives the frame 100 to move. Specifically, in the present embodiment, the traveling mechanism 200 is a crawler structure. Compared with the ordinary wheel structure, the crawler structure has the characteristics of small turning radius and strong climbing ability, which improves the adaptability of the tunnel excavation equipment to the environment, thereby expanding the scope of application of the tunnel excavation equipment.

The bucket 320 and the frame 100 are connected through the connecting arm assembly 310. The connecting arm assembly 310 drives the bucket 320 to be lifted or lowered relative to the frame 100 to excavate the tunnel; the operating arm 400 includes a cantilever assembly 410, a rotating assembly 420 and a clamping assembly 430. One end of the cantilever assembly 410 is connected to the frame 100, and the other end is connected to the rotating assembly 420. The driving end of the rotating assembly 420 is connected to the clamping assembly 430 to drive the clamping assembly 430 to rotate relative to the frame 100; the clamping assembly 430 is used to clamp the auxiliary operating mechanism 500, and the auxiliary operating mechanism 500 is used to drill, erect an arch or spray-mix reinforce the tunnel.

[0102] In the present application, when the shallow buried tunneling method is used to construct the tunnel, the walking mechanism 200 drives the frame 100 to move as a whole to the tunnel to be excavated, and at the same time, the connecting arm assembly 310 arranged on one side of the frame 100 drives the bucket 320 to be lifted or lowered relative to the frame 100 to excavate and preliminarily shape the circumferential side of the tunnel; after the general outline of the tunnel is completed, the staff will select the corresponding auxiliary operating mechanism 500 to be installed on the clamping end of the clamping assembly 430 according to the subsequent excavation operation progress, and the cantilever assembly 410 and the rotating assembly 420 arranged on the other side of the frame drive the clamping assembly 430 to move or rotate relative to the frame 100, thereby driving the auxiliary operating mechanism 500 to move or rotate relative to the frame 100, so as to drill, erect arches and spray-mix reinforce the tunnel to complete the tunnel excavation operation.

[0103] Therefore, the present application replaces the manual operation link of tunnel construction using shallow buried tunneling method in the prior art through the mutual cooperation between the digging arm 300 and the operating arm 400, which not only reduces the safety risk of tunnel construction, but also realizes the automated excavation of the tunnel and improves the efficiency of tunnel excavation.

[0104] Reference Figure 6As shown, in some embodiments, the cantilever assembly includes a base 411 and a cantilever 412, one end of the cantilever 412 is hinged to the base 411 through a first rotating shaft 440, and the other end thereof is connected to the rotating assembly 420, the base 411 is connected to the frame 100, and can swing left and right relative to the frame 100 in a vertical direction; the clamping assembly 430 is hinged to the rotating assembly 420 through a second rotating shaft 450.

[0105] Here, a base 411 is provided and configured to be able to swing left and right relative to the frame 100 around the vertical direction, thereby being able to drive the clamping assembly 430 to swing left and right relative to the frame 100, so that the operator can adjust the position of the clamping assembly 430 on the circumference in real time by controlling the rotation amplitude of the base 411, thereby improving the operating accuracy of the operating arm 400 and expanding the operable range of the operating arm 400.

[0106] Furthermore, in some embodiments, the operating arm 400 also includes a first hydraulic drive component 460 and a second hydraulic drive component 470; the two ends of the first hydraulic drive component 460 are respectively connected to the base 411 and the cantilever 412 to drive the cantilever 412 to rotate around the first rotating shaft 440; the two ends of the second hydraulic drive component 470 are respectively connected to the rotating assembly 420 and the clamping assembly 430 to drive the clamping assembly 430 to rotate around the second rotating shaft 450.

[0109] In the above embodiment, the cantilever is configured to be formed by a first sleeve 412a and a second sleeve 412b, and the second sleeve 412b is configured to be extendable or retractable relative to the first sleeve 412a, so that the operator can adjust the position of the clamping assembly 430 on the circumferential radius in real time by controlling the extension distance of the second sleeve 412b, thereby further expanding the operable range of the operating arm 400; at the same time, in actual application, the extension and retraction of the third hydraulic drive component 480 can drive the second sleeve 412b to move relative to the first sleeve 412a, that is, drive the clamping assembly 430 to move relative to the frame 100 along the extension direction of the first sleeve 412a.

[0110] In some embodiments, the clamping assembly 430 includes a support seat 431, a clamping gripper 432 and a driving member 433. The clamping gripper 432 is inserted into a mounting hole opened on the support seat 431. The driving end of the driving member 433 is connected to the clamping gripper 432 to drive the clamping gripper 432 to rotate relative to the support seat 431. The support seat 431 is hinged to the rotating assembly 420 through a second rotating shaft 450.

[0111] In the above embodiment, a driving member 433 is provided to drive the clamping gripper 432 to rotate relative to the support seat 431, so that the operator can adjust the direction of the operating end of the auxiliary operating mechanism 500 clamped on the clamping assembly 430 in real time through the driving member 433, thereby improving the efficiency of tunnel excavation.

[0112] Meanwhile, in practical applications, the clamping distance between the clamping ends of the clamping gripper 432 should be set to be adjustable according to the clamping requirements of different auxiliary operating mechanisms 500 to expand the applicable range of the tunnel excavation equipment.

[0113] Reference Figure 7 and Figure 8 As shown, in some embodiments, a grouting mechanism 600 is also included. The grouting mechanism 600 includes a water glass storage box, a stirring assembly 610 and a tee. The water glass storage box is installed on the frame 100 and is used to store water glass; the stirring assembly 610 includes a mixing barrel 611 and a grouting pump 612.

[0114] The grouting mechanism 600 includes a water glass storage box, a stirring assembly 610 and a tee, wherein the stirring assembly 610 includes a mixing barrel 611 and a grouting pump 612. When the tunnel needs to be sprayed and reinforced, cement and water are only needed to be put into the mixing barrel 611 through the feed port. After the mixing barrel 611 is fully stirred, the cement slurry is sucked out by the grouting pump 612 and mixed with water glass in the tee. The mixed liquid of water glass and cement slurry is then transported to the nozzle clamping mechanism 530, and the mixed liquid is sprayed onto the tunnel wall through the nozzle to complete the tunnel spraying operation.

[0115] Therefore, by providing the grouting mechanism 600, the conventional method of spraying and mixing the tunnel wall with a handheld nozzle by the operator is replaced, thereby improving the efficiency of tunnel excavation.

[0122] Reference Figure 5 As shown, in some embodiments, a slag transport mechanism 700 is also included, and the slag transport mechanism 700 includes a frame 710, a transport component 720 and a seventh hydraulic drive component 730. A slag transport trough 711 is opened on the frame 710, and the transport component 720 is installed in the slag transport trough 711. Both ends of the seventh hydraulic drive component 730 are respectively connected to the frame 710 and the frame 100 to drive the frame 710 to be lifted or lowered relative to the frame 100; the transport component 720 includes at least two driving shafts and a conveyor belt, each driving shaft is respectively installed in the slag transport trough 711, and the conveyor belt is wound around two adjacent driving shafts to transport slag.

[0123] The slag transport mechanism 700 includes a frame 710, a transport assembly 720 and a seventh hydraulic drive 730, wherein the transport assembly 720 includes at least two drive shafts and a conveyor belt. When it is necessary to clean the slag in the tunnel, the frame 710 is lowered by adjusting the telescopic distance of the seventh hydraulic drive 730 until the frame 710 contacts the ground, and the conveyor belts are respectively wound around the drive shafts, and the friction force generated by the surface contact between the drive shafts and the conveyor belts is converted into the power of the conveyor belts circulating between the drive shafts, thereby transporting the slag to the outside of the tunnel; after the slag in the tunnel is cleaned, the frame 710 is lifted by adjusting the telescopic distance of the seventh hydraulic drive 730 to prevent it from interfering with the ground and being damaged during the movement of the tunnel excavation equipment.

[0124] Therefore, by providing the slag transport mechanism 700, the operation method in the prior art in which workers use a handheld steel shovel to load slag is replaced, thereby improving the efficiency of tunnel excavation.
