[0002] A bridge inspection vehicle is a work platform used by bridge maintenance personnel to inspect and maintain bridges. It is a bridge-mounted inspection and maintenance tool, a specialized piece of engineering equipment used for mobile inspection and maintenance. It allows maintenance personnel to safely and quickly access locations requiring inspection and perform bridge maintenance. Currently, bridge maintenance organizations are investing in unmanned inspection vehicles to meet increasing inspection frequency and efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-7 The utility model provides a technical solution: an automatic charging device for an unmanned bridge maintenance vehicle, comprising: a steel beam bottom plate 1, the steel beam bottom plate 1 being the bottom steel body of the bridge, a walking track 2 being fixed to the bottom of the steel beam bottom plate 1, a maintenance vehicle equipment body 3 being installed on the walking track 2 at the bottom of the steel beam bottom plate 1, a signal reflecting plate 5 and one of the proximity switches 7 being installed on the walking track 2, a proximity sensor 6 being installed on the maintenance vehicle equipment body 3, and the maintenance vehicle equipment body 3 being used for repairing the bridge;

[0026] The automatic charging body 4 is arranged at the bottom of the steel beam bottom plate 1. The automatic charging body 4 includes a guide plate 45 installed on one side, which makes it possible for the current collector to achieve zero error when docking with the busbar 41. The automatic charging body 4 is used to realize an automatic charging device.

[0027] The automatic charging body 4 includes a busbar 41 disposed below the steel beam base plate 1, a connecting plate 2 43 mounted on the outside of the busbar 41, and a connecting plate 1 42 mounted on the bottom of the steel beam base plate 1. The connecting plate 1 42 and the steel beam base plate 1 are connected by bolts and nuts. The bottom of the busbar 41 is provided with a U-shaped groove, through which a charging contact body 44 is slidably mounted. The charging contact body 44 includes a deceleration limiter and a parking limiter. The deceleration limiter uses an ultrasonic sensor for deceleration detection. When the maintenance vehicle equipment body 3 reaches the parking deceleration position, the maintenance vehicle equipment body 3 is forced to decelerate to a safe speed, facilitating docking of the automatic charging device. In addition, the parking limiter uses an ultrasonic sensor for parking detection. When the maintenance vehicle equipment body 3 reaches the parking position, the maintenance vehicle equipment body 3 is forced to stop, facilitating normal charging of the automatic charging device. The automatic charging body 4 also includes two guide plates 45 docked and mounted at one end of the busbar 41, and the guide plates 45 are in a bell-shaped state. The automatic charging body 4 also includes a protruding block 46 fixed on the top of the guide plate 45, a connecting ear 47 fixed at the middle position of the protruding block 46, and a clamping sleeve 48 slidably mounted on the protruding block 46. The connecting ear 47 can be used to fix the two symmetrically assembled guide plates 45. The protruding block 46 is viewed from the side as a "T"-shaped setting, and the clamping sleeve 48 and the protruding block 46 are viewed from the side as a T-shaped sliding connection, so that the two symmetrical guide plates 45 can be quickly installed on the busbar 41; a current collector is installed at one of the fixed positions on the maintenance vehicle equipment body 3. When the maintenance vehicle equipment body 3 is automatically docked, the current collector enters the busbar 41 and contacts the busbar 41 through the collector column of the current collector, thereby connecting to the mains electricity. It is impossible for the current collector to achieve zero error when docking with the busbar 41. In order to allow the current collector to accurately enter the busbar 41, the guide plate 45 guides the current collector.

[0028] Working principle: When the maintenance vehicle equipment body 3 is performing maintenance work on the entire line, when the power is lower than the set value, the maintenance vehicle equipment body 3 returns to the parking point and automatically charges. First, the proximity sensor 6 slowly moves the maintenance vehicle equipment body 3 at a speed of ≤6m / min and gradually approaches the signal reflector 5. When entering the area of ​​the signal reflector 5, the proximity sensor 6 obtains a signal, which is transmitted to the control system of the maintenance vehicle equipment body 3 through the control circuit. According to the initially set program, the control system then issues an instruction to decelerate the walking motor. At this time, the walking motor decelerates to the initially set speed and continues to travel at a slower speed. When approaching the switch 7 and also entering the automatic charging body 4, the proximity switch 7, in the same way, sends a signal to the control system, and then issues a command to stop the reducer through the control system. At this time, the reducer stops rotating and the maintenance vehicle equipment body 3 stops running.

[0029] At the same time, the current collector on the maintenance vehicle equipment body 3 and the charging contact device installed at the charging point at the bottom of the beam begin to gradually contact according to the set position after the proximity sensor 6 is activated and the maintenance vehicle main equipment slows down. First, the current collector is made to enter the front end of the charging contact body 44 through the inclined design of the guide plate 45. Since the maintenance vehicle equipment body 3 is moving slowly, the current collector and the maintenance vehicle equipment body 3 slowly slide from the front section of the charging contact device to the middle and rear section of the charging contact device. When the proximity switch 7 is activated, according to the established program setting, the maintenance vehicle equipment body 3 stops running. At the same time, the current collector on the maintenance vehicle equipment body 3 also just stops at the middle and rear section of the charging contact device.

[0030] Once the vehicle body 3 reaches the designated location and the current collector is properly connected to the charging contactor, the utility begins charging the vehicle's lithium-ion battery according to the initial settings. Charging time varies slightly depending on the battery's storage capacity and other factors. When fully charged and reaching the set threshold, the battery's built-in BMS automatically shuts off. Although the current collector and charging contactor remain in contact, charging is complete.

[0031] The fully charged maintenance vehicle equipment body 3 can return to the last return point according to the user's needs to continue the unfinished maintenance work last time, or it can stop at a docking point and charge the vehicle according to needs to wait for the next maintenance task.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
