This operation method first requires drilling holes with a rock drilling trolley, and then dangerous explosives must be manually placed in the holes, and then the explosives must be detonated to blast the rocks, and finally the slag after blasting is transported out by loading and unloading machinery to complete an operation cycle.

[0103] In rock-related tunnel construction operations such as building tunnels in mountains and mining, various types of rock structures such as sandstone and granite are usually encountered, and they change continuously with the change of depth. The construction schemes adopted for each different type of surrounding rock are also different. The working principle of this utility model is:

[0104] like Figure 1 , Figure 2 As shown, when encountering loose surrounding rocks such as sandy rock and cotton rock, the shoveling and displacement mechanism 1 shovels and loads the sand and slag and flips them into the long trough of the slag conveying mechanism 4 under the action of the lifting cylinder 1-2, the flipping cylinder 1-1 and the chassis walking mechanism 6, and under the action of the driving sprocket and the conveying trough scraper 4-3, the slag is moved backward and loaded onto the vehicle behind, so that the slag can be easily transported away.

[0105] like Figure 4 and Figure 7 As shown, when encountering larger rocks during construction, direct shoveling cannot be completed. At this time, the shovel side plates 1-9 on both sides of the shovel displacement mechanism 1 are removed, and the rock crushing mechanism 2 on the sliding rod is slid forward to the shovel bottom plate 1-10 of the shovel displacement mechanism 1, and the shovel displacement mechanism 1 and the shovel bottom plate 1-10 are fixed with bolts through the mechanism mounting holes 1-11; then, the support cylinder 9-1 of the hydraulic support mechanism 9 is turned on, so that the cylinder piston 9-5 is extended and pressed against the ground, so that the entire front end of the machine is lifted and supported; further, the lifting cylinder 1-2 is turned on, and at this time the shovel displacement mechanism 1 is lifted up and down under the operation of the lifting cylinder 1-2, and the rock crushing mechanism 2 is used to The translation screw mechanism 2-8 is pushed to realize the horizontal movement of the breaker hammer, and the swing cylinder 2-10 is turned on. The action of the swing cylinder 2-10 will cause the breaker hammer body 2-2 to have a small range of deflection, and then the crushing propulsion cylinder 2-4 is turned on. The crushing propulsion cylinder 2-4 will promote the movement of the hammer body bottom plate 2-3 back and forth. At this time, the breaker hammer body 2-2 can reach any position under the above-mentioned composite action, and under the power drive of the hydraulic breaker hammer body 2-2, the rock is crushed and peeled off into slag through the breaker hammer drill rod 2-1. After the above operations are completed, the rock crushing mechanism 2 is disassembled and sent back to the upper middle position of the slag conveying mechanism 4, and the above-mentioned slag loading operation process is repeated to successfully carry out the construction.

[0106] like Figure 3 and Figure 8As shown, a large number of granite mountains with high hardness are often encountered during construction. At this time, the support cylinder 9-1 of the hydraulic support mechanism 9 is turned on to extend the cylinder piston 9-5 and press it against the ground, so that the front end of the entire machine is lifted up and stabilized, and the rock rotary excavation mechanism 7 is moved from the two sides of the slag conveying mechanism 4 to the push shovel bottom plate 1-10 of the shovel displacement mechanism 1 by using the cantilever hoisting mechanism 8. The rotary excavation fixed bottom plate 7-13 of the rock rotary excavation mechanism 7 is fixed to the push shovel bottom plate 1-10 by bolts through the mechanism mounting holes 1-11. The lifting cylinder 1-2 is turned on. At this time, the shovel displacement mechanism 1 is lifted up and down under the operation of the lifting cylinder 1-2. At this time, the deflection power 7-12 of the rock rotary excavation mechanism 7 drives the brake reducer 7-11 to rotate and drive The rotary support column 7-20 and the propulsion guide rail 7-4 deflect together to realize the position change of the rotary drill bit 7-2 in the drilling tool to reach the required position. The propulsion box 7-16 moves forward along the propulsion guide rail 7-4 through the propulsion screw mechanism 7-5 under the action of the propulsion power 7-10 and the rotary reducer 7-9. The rotary power 7-8 transmits the rotational power to the guide drill rod 7-3 through the drill rod seat 7-6. Under the action of forward propulsion and rotational power, the rotary drill bit 7-2 drives the highly wear-resistant cobalt alloy teeth 7-1 to cut and peel the granite. During the construction process, cooling water is sent to the cobalt alloy drill teeth 7-1 through the cooling water inlet 7-7 and the hollow guide drill rod 7-3 for cooling, and the rock fragments in the drilling process are taken out. Through the above-mentioned continuous multiple rotary drilling method, the surrounding areas of the rock mass to be excavated are drilled, cut off, and taken out one by one, and the excavation of hard granite is achieved without blasting.

[0107] like Figure 2 As shown, during the entire tunnel excavation operation, the chassis traveling mechanism 6 generates forward or backward power under the action of the traveling driving wheel 6-2, and the cable retracting mechanism 3 follows the chassis traveling mechanism 6 to move forward and backward to release or retract the power cable.

[0108] The realization of all the above-mentioned control actions is achieved by relying on the wireless remote control system 5. By selecting the four operation modes of slag loading, walking, rotary drilling or crushing, various actions of the above-mentioned operations are completed respectively under the control of the left cross rocker 5-11 or the right cross rocker 5-6; and, through the circuit conversion of the remote control chassis 5-14, the control signal is sent to the PLC control cabinet 5-23 via the remote control sending antenna 5-1 to receive and process it into a control signal, thereby controlling the start and stop of various electrical components. At the same time, it can control the push rod motor 5-18 to push the valve core push rod 5-20 of the remote control valve group 5-16 through the elastic connector 5-19 to make various hydraulic components produce corresponding actions, thereby realizing wireless remote control operations; the wireless camera 5-21 sends the signal it generates to the remote control chassis 5-14, which is displayed in front of the operator through the monitoring display screen 5-1 after being received by the monitoring receiving antenna 5-15, thereby realizing long-distance wireless control, keeping the operator away from danger, and ensuring safety.

[0109] To sum up, the multifunctional tunnel construction machinery provided by the utility model expands the use function of the machinery by adding a rock crushing mechanism 2 and a rock rotary drilling mechanism 7 to meet the special requirements of tunnel construction, realizes blasting-free excavation in tunnel construction, and has multiple uses in one machine. It is environmentally friendly and efficient, and is not only novel and compact, but also more practical and versatile.
