Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, and more specifically, to an industrial robot for rapid tunnel excavation. Background Art

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. Industrial robots are often used to assist in tunnel excavation.

[0003] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities. Industrial robots are widely used in various industrial fields such as electronics, logistics, chemical industry, and construction.

[0004] However, it still has some drawbacks in practical use, such as:

[0005] First, existing industrial robots generate heat during use. If this heat accumulates, it can damage internal components, thus increasing costs.

[0006] Second, when using existing industrial robots, since the height of the industrial robot is fixed, if the height of the tunnel to be excavated is greater than the height of the industrial robot, it will be inconvenient for the industrial robot to work, thereby reducing the working efficiency of the equipment.

[0007] Third, when existing industrial robots are in use, they generate dust when digging tunnels. Once the dust is dispersed, it will affect the work of on-site personnel, thereby reducing the practicality of the equipment. Summary of the Invention

[0008] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an industrial robot for rapid tunnel excavation. By incorporating a lifting assembly, when the height of the tunnel to be excavated exceeds the height of the industrial robot, the lifting column inside the lifting assembly is first energized to activate it. The lifting column then moves the mounting frame and stabilizing suction cup downwards until the lower surface of the stabilizing suction cup contacts the working surface. At this point, the force generated by the lifting column acts in the opposite direction, raising the height of the industrial robot body until the height of the crushing component at the bottom of the robotic arm meets the tunnel excavation height, thereby saving working time and solving the problems mentioned in the background art.

[0036] The working process of this invention is as follows:

[0037] To improve the efficiency of the industrial robot during operation, a lifting assembly 3 is installed. When the height of the tunnel to be excavated is greater than the height of the industrial robot, the lifting column 32 inside the lifting assembly 3 is first energized to activate it. The lifting column 32 then moves the mounting frame 31 and the stabilizing suction cup 37 downwards until the lower surface of the stabilizing suction cup 37 contacts the working ground. At this point, the force generated by the lifting column 32 acts in the opposite direction, raising the height of the industrial robot body 5 until the height of the crushing assembly 7 at the bottom of the robotic arm 6 meets the tunnel excavation height. To save time, and secondly, to reduce costs when the industrial robot is working, a cooling device 8 and a ventilation hole 72 are installed. When the crushing component 7 is working, the components inside the mounting shell 71 will generate heat. At this time, the drive motor 85 inside the cooling device 8 is powered on. Then, the drive motor 85 will drive the drive shaft 86 and the cooling blades 87 to rotate through the fourth bearing 84. The rapidly rotating cooling blades 87 can generate wind, which dissipates the heat generated inside the mounting shell 71 through the ventilation hole 72, thereby ensuring the quality of the components inside the mounting shell 71 and reducing losses.

[0038] In the above scheme, the industrial robot is equipped with a dust suppression device 9 to reduce dust dispersion during operation. When the crushing component 7 is working, the centrifugal pump 92 inside the dust suppression device 9 is powered on. Then, the centrifugal pump 92 will transport the liquid stored in the liquid storage tank 97 to the connecting hose 93 through the connecting bend 96. Then, the connecting hose 93 will transport the liquid to the rectangular tube 94. Finally, the atomizing nozzle 95 will spray the transported liquid out, so that the dust generated during crushing will fall to the ground, thereby enhancing the practicality of the device.
