Description

A mining drilling vehicle Technical Field

[0001] The utility model relates to the technical field of mining engineering, in particular to a mining excavation drilling vehicle. Background Art

[0002] During the mining process of underground metal mines, it is necessary to carry out excavation drilling and blasting operations in underground mine transportation tunnels. In small and medium-sized underground metal mine tunnels, excavation drilling is still mainly done by manual handheld air guns. Manual handheld air gun drilling has problems such as high labor intensity, harsh working environment, low construction efficiency, low drilling accuracy, and difficulty in controlling overbreak and underbreak. In addition, there are great safety hazards, high construction costs and high labor costs. With the development of the economy, the number of people engaged in the domestic mining industry has been greatly reduced, especially the number of people engaged in hand-held air drills. Therefore, underground metal mines urgently need to promote mechanized construction.

[0003] Currently, domestic mines are implementing strategies of mechanized replacement and reduction of manpower, and are gradually introducing mechanized equipment for drilling operations. Patent CN212867389U discloses a single-arm rock drilling rig, comprising a powertrain body and a driving and operating body. Both the powertrain body and the driving and operating body are provided with a running mechanism at their bases, and the powertrain body and the driving and operating body are detachably connected. The driving and operating body is provided with a drill arm mechanism for adjusting its orientation, and a rock drilling mechanism for tunnel excavation is horizontally located above the drill arm mechanism. While this rig can replace manual drillers and effectively increase excavation speed, its drill arm is limited in functionality, only capable of lifting and leveling the excavation mechanism. This rig cannot meet the complex and changing operating conditions of mines.

DETAILED DESCRIPTION

[0025] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Among them, the directional terms such as "front", "back", "left", and "right" mentioned herein are with reference to the orientation of Figure 2.

[0026] As shown in Figures 1 and 2, this embodiment provides a mining tunneling drill vehicle, comprising a vehicle body 1, a drill boom assembly, and a tunneling mechanism 3. The drill boom assembly includes a telescopic arm mechanism 21, a lifting actuator 22, a leveling mechanism 23, a tilting mechanism 24, and a yaw mechanism 25. The telescopic arm mechanism 21 is rotatably mounted at one end to the vehicle body 1. The lifting actuator 22 is mounted to the vehicle body 1 and is connected to the telescopic arm to drive the telescopic arm mechanism 21 to rotate within a vertical plane. The leveling mechanism 23 is mounted on the telescopic arm, the tilting mechanism 24 is mounted to the leveling mechanism 23, the yaw mechanism 25 is mounted to the tilting mechanism 24, and the tunneling mechanism 3 is mounted to the yaw mechanism 25.

[0027] Specifically, the forward and backward displacement and height lifting of the tunneling mechanism 3 are realized through the telescopic arm mechanism 21 and the lifting drive 22, and the self-sustaining horizontal state of the tunneling mechanism 3 during the lifting process is ensured by the leveling mechanism 23; the flipping mechanism 24 and the yaw drive 252 can realize the rotation of the tunneling mechanism 3 in the vertical plane and the left and right yaw angle adjustment, thereby adapting to the complex and changeable working conditions in mine drilling operations. Compared with the existing technology, it can not only replace manual labor and ensure working efficiency, but also adapt to the complex and changeable working conditions in mines.

[0028] Furthermore, as shown in Figures 3 and 4, the leveling mechanism 23 includes a leveling mount 231, a leveling driver 232, and a leveling connector 233. The leveling mount 231 is mounted at the end of the telescopic arm mechanism 21, the leveling connector 233 is rotatably mounted to the leveling mount 231, the flip mechanism 24 is mounted to the leveling connector 233, and the leveling driver 232 is mounted to the leveling mount 231. The leveling driver 232 is connected to the leveling connector 233 to drive the leveling connector 233 to rotate in a vertical plane, thereby driving the excavation mechanism 3 to achieve angle adjustment in the vertical plane and ensure that the excavation mechanism 3 remains horizontal.

[0029] Furthermore, as shown in Figures 3 and 4, the tilting mechanism 24 includes a tilting actuator 241 and a tilting connector 242. The tilting actuator 241 is mounted on the leveling mechanism 23, the tilting connector 242 is mounted on the tilting actuator 241, the tunneling mechanism 3 is mounted on the tilting connector 242, and the yaw mechanism 25 is mounted on the tilting connector 242. The tilting actuator 241 is capable of rotating the tilting connector 242, with its rotation axis oriented forward and backward. The tilting actuator 241, through the tilting connector 242, drives the tunneling mechanism 3 to rotate forward and backward, adapting to various complex working conditions.

[0030] Furthermore, as shown in Figures 3 and 4, the yaw mechanism 25 includes a base 251, a yaw driver 252, and a propulsion driver 253. The base 251 is rotatably mounted to the tilting mechanism 24, and the tunneling mechanism 3 is slidably mounted to the base 251. The propulsion driver 253 is mounted to the base 251 and connected to the tunneling mechanism 3 to drive the tunneling mechanism 3 to slide back and forth. The yaw driver 252 is mounted to the tilting mechanism 24 and connected to the base 251, driving the base 251 to rotate the tunneling mechanism 3 in the horizontal plane, thereby adjusting the yaw angle of the tunneling mechanism 3 to the left and right within the tunneling section.

[0031] As shown in Figure 4 , the tunneling mechanism 3 includes a propulsion beam 31, a rock drill 32, and a drill support 33. The propulsion beam 31 is mounted on the yaw mechanism 25, while the rock drill 32 and drill support 33 are mounted on the propulsion beam 31. The drill bit of the rock drill 32 slides through the drill support 33 to meet the requirements of rock drilling. A rubber pad 34 is installed at the front end of the propulsion beam 31 to provide collision protection. In this embodiment, the propulsion beam 31 is mounted on the base 251 of the yaw mechanism 25.

[0032] Furthermore, as shown in Figure 1, the vehicle body 1 includes a chassis 11, and a cab 12, a lifting roof 13, an engine 14, an air compressor, a hydraulic system, a water pump, and a cable drum installed on the chassis 11. The cab 12 is located in the middle of the chassis 11, and the lifting roof 13 is located above the cab 12 to ensure the safety of the personnel while driving. The engine 14, the air compressor, the hydraulic system, the water pump, and the cable drum are located at the rear end of the chassis 11, and one end of the telescopic arm mechanism 21 is rotatably mounted on the front end of the chassis 11. This balances the center of gravity of the chassis 11, avoids rollover, and facilitates the operator to maintain the equipment. The cab 12 is equipped with a hydraulic control handle for the movement of the drill arm assembly and drilling operations and a related parameter display. The display can display the working time of the water pump, engine 14, air compressor, rock drill, etc. and can display fault information, which can assist on-site personnel in quickly handling faults. In this embodiment, the chassis 11 is an articulated chassis. Its axle drive system utilizes a hydraulic transmission and four-wheel drive. The drive axle utilizes a spring-braked, hydraulically released, fully enclosed wet-type drive axle. This optimized hydraulic transmission delivers stable performance and powerful power, making it ideal for maneuvering through narrow, complex underground tunnels. The hydraulic system connects the tunneling mechanism 3, telescopic arm mechanism 21, lift actuator 22, leveling actuator 232, tilt actuator 241, and yaw actuator 252, providing power for the drill boom assembly. This prevents runaway and sticking of the rock drill 32 in the tunneling mechanism 3, and adjusts parameters in real time based on the working conditions, reducing consumption of drilling tools such as drill tails and drill bits, thereby improving drilling efficiency and achieving high efficiency.
