[0033] Example 1

[0034] like Figures 1 to 9 As shown, a remote operation simulation platform device based on a single-arm drilling rig in a well, according to the first aspect of this utility model, includes a chassis 1, a fence 2, a safety canopy operating platform 3, a driving operating platform 4, a steering wheel 5, a working operating platform 6, a seat 8, and multiple electric cylinders 12.

[0035] The chassis 1 is made of integral welded steel sections. The bottom of the chassis 1 is equipped with a truss structure 15. The fence 2 is made of integral welded steel sections and sheet metal sections. The fence 2 is installed around the outer edge of the chassis 1. The fence 2 and the chassis 1 are connected and fixed with high-strength bolts. The fence 2 and the chassis 1 together form the operating room.

[0036] Both the seat 8 and the steering wheel 5 are located in the control room. The steering wheel 5 is located in front of the seat 8, and the accelerator pedal 10 and the brake pedal 11 are located below the steering wheel 5.

[0037] The safety canopy operating platform 3, driving operating platform 4, and working operating platform 6 are all located inside the guardrail 2. The safety canopy operating platform 3 is made of sheet metal through bending and welding, and is fixed to the guardrail 2 with high-strength screws. The safety canopy operating platform 3 controls the opening and closing function of the safety canopy, and its specific structural components and layout are the same as the corresponding modules on the original vehicle. The driving operating platform 4 is made of sheet metal through bending and welding, and is fixed to the chassis 1 and the guardrail 2 with high-strength screws. The driving operating platform 4 remotely controls the original vehicle's movement, steering, and braking (including the steering wheel 5, accelerator pedal 10, and brake pedal 11), and its specific structural components and layout are the same as the corresponding modules on the original vehicle. The working operating platform 6 is made of sheet metal through bending and welding, and is fixed to the guardrail 2 with high-strength screws. The working operating platform 6 mainly controls the original vehicle's drilling function, and its specific structural components and layout are the same as the corresponding modules on the original vehicle.

[0038] Multiple electric cylinders 12 are arranged in a ring along the chassis 1. The output shaft 13 of each electric cylinder 12 is vertically downward and passes through the chassis 1. The electric cylinders 12 are used to realize lifting, pitching and tilting actions.

[0039] It also includes a display screen that shows the movement status of the single-arm rock drilling rig in the underground tunnel, including environmental videos from the front, back, left, and right perspectives of the single-arm rock drilling rig, as well as the speed, angle, and movement videos of each rotating axis.

[0040] In this embodiment, it should be noted that the electric cylinder 12 is a high-precision servo electric cylinder, and there are four electric cylinders 12 arranged in a rectangular shape. The motion simulation controller, servo driver and the four electric cylinders 12 together form a three-degree-of-freedom platform. According to the vehicle body posture information collected from the original vehicle, the motion simulation controller controls the four electric cylinders 12 to move in tandem, so that the simulation platform moves to the same posture state as the underground vehicle. The simulation platform has three degrees of freedom of motion functions: lifting, pitching and rolling (tilting), simulating the state of the trolley vibrating up and down, swaying left and right, and bumping back and forth in the underground. The four electric cylinders 12 are connected to the chassis 1 through the shaft end flange structure, which reduces the installation space and increases the overall aesthetics. The shaking of the equipment during operation is consistent with that of the real vehicle.

[0041] The safety canopy operating platform 3 is located on the right side of the seat 8, the driving operating platform 4 is located on the front side of the seat 8, and the work operating platform 6 is located on the left side of the seat 8.

[0042] Furthermore, this device is used in conjunction with the original vehicle or VR system. When used with the original vehicle, the specific structure of the original vehicle is as follows: Figure 9As shown, a series of intelligent modifications are needed to the original single-arm rock drilling rig. This includes adding an onboard controller (to control the communication protocol of the original onboard electrical control box), a data acquisition unit, and auxiliary control devices (tilt sensor, angle sensor, inertial navigation system, scanner, and camera). The onboard electrical control box and data acquisition unit are installed near the original electrical control box. The tilt sensor is installed inside the onboard electrical control box, and the angle sensor is installed on each rotating axis of the drill arm. The inertial navigation system and scanner are installed on the central plane of the single-arm rock drilling rig. Four cameras (front, rear, left, and right) are installed at corresponding positions on the front, rear, left, and right sides of the single-arm rock drilling rig. The equipment control functions are integrated into the remote operation simulation platform via network protocols. When used in conjunction with a VR system, a virtual simulation software system is employed. The software includes functions such as a virtual driving operation module, driving scenarios, 3D vehicles, navigation maps, perspective switching, virtual effect display modules, and a scoring system. This ensures that the equipment operation and rotating shaft movements conform to the real material movement laws, reproducing the actual working state of the equipment underground. It provides users with a realistic and safe driving experience, simulating real driving operations. It features high fidelity to real vehicle operation, multiple scenarios, and high safety and reliability, and can be used for driving instruction, training, and testing.

[0043] The technical effects achieved in this embodiment are as follows: by setting multiple electric cylinders 12, and using multiple electric cylinders 12 in combination, lifting, pitching and tilting actions can be realized, thereby simulating the state of the trolley vibrating up and down, swaying left and right, and bumping back and forth underground; through the safety canopy operating platform 3, driving operating platform 4, steering wheel 5, working operating platform 6, accelerator pedal 10 and brake pedal 11, the trolley's movement, steering and various operating actions underground can be controlled or simulated; the remote operating platform can be moved to a designated location to control the operation of underground equipment, which not only improves the working environment of drivers and workers and reduces labor intensity, but also avoids the safety risks of personnel operating underground. This device can also be used for driving teaching and training examinations of single-arm rock drilling trolley drivers.

[0046] In this embodiment, the electric cylinder 12 is provided with a protective cover 7. The protective cover 7 is made of sheet metal by bending and welding, and is fixed to the chassis 1 and the fence 2 with high-strength screws.

[0047] In this embodiment, it should be noted that a driver protection structure is also included. The driver protection structure is housed inside the protective cover 7 and is electrically connected to the electric cylinder 12. The driver protection structure is a key component to ensure the safe operation of the electric cylinder 12 under various working conditions, and mainly includes the following aspects: Overload protection: By monitoring parameters such as the driver's operating current or temperature, a protection mechanism is triggered when the set threshold is exceeded to prevent damage to the driver; Undervoltage protection: The driver's power supply voltage is monitored, and protection is activated when the voltage is lower than the normal operating range to prevent the driver from malfunctioning due to undervoltage; Short circuit protection: A short circuit detection circuit is set at the driver output terminal. Once a short circuit fault is detected, the output is immediately cut off to protect the driver and the load; Fault detection and protection circuit: Integrated inside the driver circuit, such as an intelligent power module (IPM), which has fault detection and protection functions for overvoltage, overcurrent, and overheating.

[0048] The technical effects achieved by this embodiment are as follows: by setting the protective cover 7, the electric cylinder 12 can be well protected and prevented from being damaged; by setting the driver protection structure, the stable operation of the electric cylinder 12 can be effectively guaranteed.

[0056] In this embodiment, it should be noted that there are four casters 14, which are swivel casters, and the casters 14 are bolted to the chassis 1 using high-strength screws.

[0057] The technical effect achieved by this embodiment is as follows: when the simulation platform is working, the four electric cylinders 12 are in contact with the ground to support the weight of the equipment. When the simulation platform is not working and moving, the four electric cylinders 12 are retracted and the casters 14 are opened to complete the movement of the platform.
