[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 The present invention discloses an explosion-proof automatic charging device for an explosion-proof wheeled inspection robot, the device comprising a charging pile mounting frame (1), a horizontal slide seat (2), a vertical moving device (3), a charging contact device (4), an explosion-proof wheeled inspection robot (5), an automatic charging drive device (6), an explosion-proof charger (7), an explosion-proof wireless base station (8), and an explosion-proof wheeled inspection robot charging terminal (9).
[0016] The horizontal slide (2), the vertical moving device (3) and the charging contact device (4) are fixed on the charging pile mounting frame (1) from top to bottom. The charging contact device (4) is fastened to the vertical moving device (3) by bolts, and the vertical moving device (3) is fastened to the horizontal slide (2) by bolts. The automatic charging drive device (6) is fixedly mounted on a bracket behind the charging pile mounting frame (1) and is electrically connected to the explosion-proof charger (7). The explosion-proof wireless base station (8) is connected to the automatic charging drive device (6) by a cable and communicates with the explosion-proof wheeled inspection robot (5) by wireless means. The charging end (9) of the explosion-proof wheeled inspection robot is mounted at the front end of the explosion-proof wheeled inspection robot (5) and is in close contact with the charging contact device (4) during charging. The charging contact device (4) is connected to the explosion-proof charger (7) by a cable.
[0017] The automatic charging drive device (6) is composed of a drive housing, an explosion-proof end cover, a drive shaft, an explosion-proof spacer, a motor, a reducer, and an explosion-proof nozzle. The motor is connected to the drive shaft through the reducer and installed in the drive housing. The drive housing, the explosion-proof end cover, the explosion-proof spacer, and the explosion-proof nozzle form an independent, closed warehouse in an explosion-proof form, meeting the national ⅡC explosion-proof requirements.
[0018] The charging contact device (4) is composed of a guide sleeve, a copper column, a charging plug, a flameproof charging contact, a locking limit column, a locking compression spring, a gear transmission device and a threaded transmission device. The charging plug and the flameproof charging contact are fastened to the copper column by explosion-proof locking screws. The copper column is located inside the guide sleeve and can make linear motion through the guide sleeve. The driving shaft of the automatic charging drive device (6) is connected to the gear transmission device, and the gear transmission device is connected to the copper column through the threaded transmission device. The gear transmission device and the threaded transmission device cooperate to convert the rotational motion of the driving shaft into the linear motion of the copper column. The locking compression spring is connected to the locking limit column and is located inside the guide sleeve. When the copper column moves linearly, it drives the locking limit column to make linear motion in the same direction. At the same time, the locking limit column can be extended or retracted from the guide sleeve through the locking compression spring.
[0019] The horizontal slide (2) is composed of a slide, a slider, a guide column and a spring, which are connected by a bolt structure and are used to provide the charging contact device (4) with horizontal freedom when the explosion-proof wheeled inspection robot (5) starts charging, so as to ensure that the explosion-proof wheeled inspection robot (5) and the explosion-proof automatic charging device of the explosion-proof wheeled inspection robot can be flexibly, buffered and accurately connected.
[0020] The vertical moving device (3) is composed of a mounting frame, a support plate, a limit block, a limit column, a return spring and a limit plate. The mounting frame and the support plate are connected by a hinge. The limit block, the limit column, the return spring and the limit plate form a spring compression device, which is connected to the mounting frame by bolts to form a vertical moving device that can move up and down.
[0021] The explosion-proof charger (7) is composed of an explosion-proof charger box, an explosion-proof box cover 1, a knob handle switch, an explosion-proof wire nozzle 2, and an electrical component part 1. The explosion-proof charger box, the explosion-proof box cover 1, and the explosion-proof wire nozzle 2 form an independent, closed box in a flameproof form, the electrical component part 1 is installed inside the box, and the knob handle switch is installed on the box. The explosion-proof charger (7) provides charging power for the explosion-proof automatic charging device of the explosion-proof wheeled inspection robot, meeting the national ⅡC explosion-proof requirements.
[0022] The explosion-proof wireless base station (8) is composed of an explosion-proof wireless base station box, an explosion-proof box cover 2, an explosion-proof wire nozzle 3, and an electrical component part 2. The explosion-proof wireless base station box, the explosion-proof box cover 2, and the explosion-proof wire nozzle 3 are fastened and connected by bolts to form an independent, closed explosion-proof chamber, and the electrical component part 2 is installed inside the explosion-proof chamber. The explosion-proof wireless base station (8) meets the national ⅡC explosion-proof requirements.
[0023] The working process of the present invention is as follows: when the explosion-proof wheeled inspection robot (5) detects that its own power is lower than a certain set value, the charging process is started. The explosion-proof wheeled inspection robot (5) drives towards the explosion-proof automatic charging device of the explosion-proof wheeled inspection robot, and aligns the charging end (9) of the explosion-proof wheeled inspection robot with the charging contact device (4). The charging contact device (4) is adjusted by the movement of the horizontal slide (2) and the vertical moving device (3), and uses the cone structure to align and position with the charging end (9) of the explosion-proof wheeled inspection robot. When the charging contact device (4) is aligned with the charging end (9) of the explosion-proof wheeled inspection robot, the explosion-proof wheeled inspection robot (5) stops moving, and sends a charging request instruction to the automatic charging drive device (6) through the explosion-proof wireless base station (8). After the automatic charging drive device (6) receives the signal sent by the explosion-proof wireless base station (8), the motor is started to work, thereby driving the drive shaft to rotate, and the gear transmission device and the thread transmission device of the charging contact device (4) convert the rotational motion of the drive shaft into the linear motion of the copper column. When the copper column moves linearly, it drives the locking limit column to move linearly in the same direction, the locking compression spring is compressed, and the locking limit column extends from the guide sleeve, triggering the charging locking device of the explosion-proof wheeled inspection robot, so that the charging contact device (4) and the charging end (9) of the explosion-proof wheeled inspection robot form a locking structure. The copper column continues to move linearly, and when it moves to a specified position, the motor stops rotating. At this time, relying on the compression effect of the spring, the flameproof charging contact of the charging contact device (4) is completely in contact with the charging contact of the charging end (9) of the explosion-proof wheeled inspection robot, and the charging contact device (4) and the charging end (9) of the explosion-proof wheeled inspection robot form an explosion-proof closed chamber, and the explosion-proof charger (7) starts to supply power to charge the explosion-proof wheeled inspection robot (5).
[0024] When the explosion-proof wheeled inspection robot (5) is finished charging, it sends a charging completion instruction to the explosion-proof wireless base station (8), and the explosion-proof wireless base station (8) sends a signal to the automatic charging drive device (6). After receiving the signal from the explosion-proof wireless base station (8), the automatic charging drive device (6) starts the motor again to drive the drive shaft to rotate in the opposite direction, and converts the rotational motion of the drive shaft into the reverse linear motion of the copper column through the gear transmission device and the thread transmission device of the charging contact device (4). When the copper column moves in a straight line, it drives the locking limit column to move in the same direction, the locking compression spring is reset, and the locking limit column is retracted from the guide sleeve, so that the charging locking device of the explosion-proof wheeled inspection robot is reset and the locking structure is released. The copper column continues to move in a straight line, and when it moves to the initial position, the motor stops rotating. At this time, the charging process is completed. The explosion-proof wheeled inspection robot (5) leaves the explosion-proof automatic charging device of the explosion-proof wheeled inspection robot and continues to start normal inspection work.
[0025] The present invention is not limited to the embodiments described in the specific implementation manner. As long as a person skilled in the art can derive other implementation manners based on the present invention, they also fall within the scope of technical innovation and protection of the present invention.
