[0032] See also Figure 1-5 As shown, a battery online replacement device of the present invention comprises a chassis 1 and a battery box 2 for loading batteries, one end of the chassis 1 is provided with a hanging bracket 3 for installing a track, a battery replacement opening 4 adapted to the size of the battery box 2 is provided on the side wall of the chassis 1 below the hanging bracket 3; a battery replacement brush plate 5 for power exchange is provided at the front end of the battery box 2. A hinged inspection door is provided on one side of the chassis, and a glass window is provided on the inspection door. This structure facilitates observation of the interior and timely maintenance.

[0033] A double-layer lifting platform 6 is provided in the chassis 1, and a linear drive component 7 is provided on the double-layer lifting platform 6; a hook component 8 is provided on the linear drive component 7, and a U-shaped hook ear 9 matched with the hook component 8 is provided on the battery box 2; two charging modules 10 corresponding to each layer of the double-layer lifting platform 6 are provided vertically at the front end of the chassis 1. The battery box can be replaced on the double-layer lifting platform and the monitoring vehicle by cooperating with the hook component and the linear drive component, so that the battery on the monitoring vehicle can be quickly replaced, thereby improving the efficiency of battery replacement. In addition, when the battery box on the monitoring vehicle is taken out and placed in the double-layer lifting platform, it is charged through the charging module, which can realize online charging and online battery replacement, and does not require workers to repeatedly carry batteries, thereby reducing the workload of workers.

[0034] In this embodiment, the linear drive assembly 7 includes a linear motor 7 a disposed on the double-layer lifting platform 6 , and a sliding seat 7 b for mounting the hook assembly 8 is provided on the linear motor 7 a .

[0035] A first guide slide 7c is provided on the double-layer lifting platform 6, and two second guide slides 7d cooperating with the first guide slide 7c are provided at the bottom of the battery box 2; and limit baffles 7e cooperating with the battery box 2 are symmetrically provided on the double-layer lifting platform 6 on both sides of the first guide slide 7c. The battery box is positioned and guided to slide by the cooperation of the first guide slide and the second guide slide, so as to ensure that the battery box can be accurately aligned.

[0036] In this embodiment, preferably, the hook assembly 8 includes a lifting cylinder 8a disposed on the linear drive assembly 7, a mounting suspension 8b is disposed on the piston rod of the lifting cylinder 8a, and a hook plate 8c in an inverted trapezoidal shape and matched with the U-shaped hook ear 9 is disposed at the free end of the mounting suspension 8b. The hook plate is matched with the U-shaped hook ear, and the contact area between the two is large, which can reduce the possibility of the battery box being offset during the pulling process. At the same time, the two side lines of the inverted trapezoidal hook plate can play a guiding role when it is matched with the U-shaped hook ear, so that the two sides are convenient for matching.

[0037] In this embodiment, the charging module 10 includes a driving cylinder 10a disposed on the chassis 1 on one side of the double-layer lifting platform 6, and a charging brush 10c that cooperates with the battery replacement brush plate 5 is provided on the piston rod of the driving cylinder 10a through a mounting plate 10b, and the charging brush 10c is connected to an external power supply. After adopting this structure, the charging brush is located on one side of the double-layer lifting platform in the initial state, and will not interfere with the lifting of the double-layer lifting platform and the replacement of the battery box.

[0038] During operation, first move the layer of the double-layer lifting platform where the battery box is not placed to match the battery replacement opening. The linear motor and lifting cylinder cooperate to match the hook plate with the U-shaped hook ear of the battery box on the monitoring vehicle. The linear motor retreats to take out the battery box and place it on the double-layer lifting platform.

[0039] The double-layer lifting platform moves upward or downward to move a layer of the double-layer lifting platform storing fully charged batteries to cooperate with the battery replacement opening, and the linear motor drives the sliding seat forward to push out the fully charged batteries for replacement.

[0040] After the battery replacement is completed, the piston rod of the driving cylinder is extended to make the charging brush cooperate with the battery replacement brush plate at the front end of the battery box placed on the double-layer lifting platform for charging.

[0041] See also Figure 6-10As shown, a rail-type monitoring vehicle using the above-mentioned battery online replacement device of the present invention comprises a rail 11 and a mobile bracket 12 arranged on a hanging suspension 3, characterized in that a housing 13 is provided on the mobile bracket 12, a pulley 14 and a driving assembly 15 mounted on the rail 11 are provided at the upper end of the mobile bracket 12; and a monitoring head 16 is provided at the bottom of the mobile bracket 12. The monitoring head is connected to an external control terminal for real-time monitoring or video recording, and its connection method can adopt a commonly used method in the field. In this embodiment, an antenna is used for wireless transmission, and its specific structure is common knowledge of those skilled in the art and will not be repeated here.

[0042] A power slot 17 for installing the battery box 2 is provided on the mobile bracket 12 , and an opening end of the power slot 17 corresponds to the battery replacement opening 4 .

[0043] A corresponding position sensor is provided on the track. When the power slot is accurately aligned with the battery exchange opening, the monitoring vehicle stops running. This is common knowledge among those skilled in the art and will not be repeated here. A brush plate boss for battery exchange is provided at the inner end of the power slot, and a third guide slide corresponding to the first guide slide is provided on the inner bottom surface of the power slot for guidance. When the power slot is accurately aligned with the battery exchange opening, the first guide slide is connected and transitioned with the third guide slide.

[0044] By matching the power slot with the battery replacement opening, the hook component in the battery online replacement device can replace the battery box between the power slot and the battery online replacement device under the drive of the linear drive component, thereby realizing online replacement of batteries. Workers do not need to repeatedly carry batteries, which reduces workers' workload and reduces safety hazards.

[0045] In this embodiment, a long hole 18 is provided on the side wall of the battery box 2 at the U-shaped hook ear 9, and an elastic locking pin 19 is vertically provided in the battery box 2 above the long hole 18. The elastic locking pin 19 is provided with a horizontal cross bar 20 that cooperates with the long hole 18.

[0046] When the battery box 2 is located in the power slot 17, the upper end of the elastic lock pin 19 is located outside the battery box 2 and cooperates with the inner wall of the shell 13; when the hook component 8 cooperates with the U-shaped hook ear 9, the elastic lock pin 19 moves downward into the battery box 2. By setting the elastic lock pin to cooperate with the inner wall of the shell, the battery box is prevented from loosening toward the opening during the movement, ensuring that the battery box fits the battery replacement unit in the power slot to ensure power supply. And after adopting this structure, when the hook component cooperates with the U-shaped hook ear, the battery box can be automatically unlocked, which is convenient for taking out the battery box for replacement.

[0047] Further preferably, the U-shaped hook ear 9 is provided with a limiting groove 21 opposite to the long hole 18, and the free end of the horizontal cross bar 20 is located in the limiting groove 21. Since the side wall of the battery box is relatively thin, the vibration generated during use may cause the elastic lock pin to rotate, causing the horizontal cross bar to deflect and swing, resulting in the hook assembly being unable to contact the horizontal cross bar. By providing a limiting groove to cooperate with the free end of the horizontal cross bar, the horizontal cross bar can be prevented from swinging and shifting, thereby ensuring that the hook assembly can effectively push down the horizontal cross bar to achieve the downward movement of the elastic lock pin.

[0048] In this embodiment, the driving assembly 15 includes a plurality of bearing seats 15a disposed on the movable brackets 12 on both sides of the track 11; a driving wheel 15b matching the side wall of the track 11 is disposed on the bearing seat 15a on one side through a rotating shaft, and a driven wheel 15c is disposed on the bearing seat 15a on the other side through a rotating shaft. By arranging the driving wheel and the driven wheel on the side of the track for driving, the forward direction can always be kept parallel to the length direction of the track, which can effectively avoid the occurrence of jamming after the pulley is offset due to shaking.

[0049] A driving motor 15d is provided on the mobile bracket 12, and the driving motor 15d is connected to the driving wheel 15b through a transmission unit 15e; a tensioning assembly 22 is provided on the mobile bracket 12 for making the driving wheel 15b and the driven wheel 15c cooperate to clamp the track 11. The tensioning assembly enables the driving wheel and the driven wheel to always clamp the track, which can effectively reduce the shaking of the monitoring device during the movement, maintain the stability of the camera, and ensure the clarity of the monitoring video.

[0050] Further preferably, the tensioning assembly 22 comprises two guide rods 22a arranged on the mobile bracket 12 and perpendicular to the direction of the track 11, a sliding mounting seat 22b is arranged between the two guide rods 22a, and a bearing seat 15a for mounting the driving wheel 15b is arranged on the sliding mounting seat 22b; a baffle 22c is arranged at the free end of the guide rod 22a, and a tensioning spring 22d is arranged between the baffle 22c and the sliding mounting seat 22b. The sliding mounting seat is pressed against the track by the cooperation of the baffle and the tensioning spring, so that the driving wheel can always be close to the track surface, reducing the shaking of the monitoring device during the movement.

[0051] During operation, the mobile bracket moves to one side of the box so that the opening end of the power slot is matched with the battery exchange opening. With the cooperation of the linear motor and the lifting cylinder, the front end of the hook plate is inserted into the U-shaped hook ear of the battery box on the monitoring vehicle. The hook plate presses down the horizontal cross bar to open the elastic locking pin, and the linear motor retreats to take out the battery box and place it on the double-layer lifting platform.

[0052] The double-layer lifting platform moves up or down to move the layer of the double-layer lifting platform containing the fully charged battery to match the battery replacement opening. The linear motor drives the sliding seat forward to push the fully charged battery into the power slot. The lifting cylinder rises to bring the front end of the hook plate away from the U-shaped hook ear, and the elastic locking pin moves upward to fit the inner wall of the outer shell to lock it, and the battery replacement is completed.
