[0048] like Figures 1 to 12 As shown, the grabbing assembly also includes a plurality of mounting frames 2 301 arranged on the surface of the connecting plate 229, cylindrical blocks 1 302 are respectively arranged near the four corners on the upper surface of the mounting frame 2 301, and the four cylindrical blocks 1 302 are respectively fixedly connected in four circular grooves 5 opened on the upper surface of the mounting frame 2 301, and the surface of the cylindrical block 1 302 is rotatably connected to a circular tube 1 303 through a bearing 4, and the support blocks 211 are equidistantly fixedly connected to the surface of the circular tube 1 303, and the inner wall of the circular tube 1 303 is fixedly connected with a wedge block 306 in a ring array, and a pneumatic arc telescopic member for driving the circular tube 1 303 to rotate is arranged inside the circular tube 1 303.

[0049] like Figures 1 to 12As shown, the pneumatic arc telescopic member includes an arc sleeve 304 fixedly connected to the bottom surface of a cylindrical block 302, an arc slider 305 is slidably connected inside the arc sleeve 304, a connecting pipe 311 is fixedly connected inside a circular groove 6 opened on the surface of the arc sleeve 304, an air box 312 is fixedly connected to the bottom surface of the cylindrical block 302, one end of the connecting pipe 311 away from the arc sleeve 304 extends to the inside of the air box 312 through a circular groove 7 opened on the surface of the air box 312 and is fixedly connected to the air box 312, an air pipe 313 is fixedly connected inside a circular groove 8 opened on the bottom surface of the air box 312, and the air pipe 313 is away from the air box 312.

Two limit blocks 310 are fixedly connected to the surface of the air pipe 313.

[0051] like Figures 1 to 12 As shown, it should be noted that: the battery box 201 arranges the elastic electrodes 202 inside it in series and parallel through wires according to the needs of the device, and the battery box 201 is provided with a wiring port on the outside to facilitate power supply to the electrical equipment on the monorail vehicle 102. The series and parallel arrangement inside the battery box 201 is well known in the prior art and will not be repeated here;

[0052] Ball bearings may be installed on the upper surface of the support block 211, thereby reducing the friction between the support block 211 and the protective side column 206, and facilitating the relative sliding between the support block 211 and the protective side column 206;

[0053] The elastic potential energy of the coil spring 314 always has a tendency to make the rectangular sleeve 307 rotate clockwise along the axis of the air pipe 313, so that the arc-shaped slider 305 can reciprocate inside the arc-shaped sleeve 304;

[0054] When the support block 211 carries the battery block 228 through the protective side column 206 and falls into the battery box 201, the protruding support plate 204 will continuously squeeze the support plate 204 into the interior of the rectangular groove 203 through the inclined surface 2111 on the support block 211, thereby facilitating the smooth placement of the battery block 228 into the interior of the battery box 201.

[0055] Working principle: In the mountain orchard scene, the gantry crane 104 and the slide rail 103 are set at a relatively flat section of the track 101. A charging device is set on one side of the track 101, wherein a battery box 201 is also set at the charging end of the charging device. When the monorail vehicle 102 needs to replace the battery, the staff controls the monorail vehicle 102 to travel along the track 101 to the bottom of the gantry crane 104 and opens the cover of the battery box 201 on the monorail vehicle 102;

[0056] In this embodiment, a mounting frame 214 is symmetrically fixed on the surface of the connecting plate 229. The gantry crane 104 slides along the slide rail 103, so that the connecting plate 229 on the multi-stage telescopic cylinder of the gantry crane 104 drives one of the mounting frames 214 to move to the top of the battery box 201 in the charging device, and the cover of the battery box 201 is opened. The twisting column 223 is rotated, so that the ball head block 225 inside the twisting column 223 is inserted into one of the adjacent positioning grooves 227 in the positioning ring block 224 under the action of the elastic potential energy of the spring three 226. In this process, the round rod 212 is rotated ninety degrees under the drive of the sprocket 216 at the bottom end of the twisting column 223 and the transmission chain 217 on the surface of the four sprockets 216, so that the support block 211 is aligned with the avoidance groove 208 of the protective side column 206 and the multi-stage telescopic cylinder of the gantry crane 104 is The retracting cylinder is extended. The extension of the multi-stage telescopic cylinder of the gantry crane 104 causes the round rod 212 to carry the support block 211 on its surface and the sliding sleeve 218 and piston rod 219 at its bottom, and sequentially string together the battery blocks 228 in the battery box 201 through the through groove 207 on the surface of the protective side column 206. When the piston rod 219 moves upward to the maximum distance inside the sliding sleeve 218, the positioning block 213 on the surface of the round rod 212 fits with the uppermost protective side column 206. At this time, the twisting column 223 is rotated again to rotate the round rod 212 ninety degrees again. During this process, the support block 211 rotates ninety degrees inside the rotary groove 210 and pushes out the spring 205 originally inserted into the support groove 209. At this time, the multi-stage telescopic cylinder on the gantry crane 104 is retracted, and the battery block 228 located inside the battery box 201 is pulled out.

[0057] In this embodiment, another mounting frame 214 is moved to above the battery box 201 in the monorail vehicle 102, and the battery block 228 inside it is pulled out in the same way, and the battery block 228 pulled out from the charging device is rotated to above the battery box 201 on the monorail vehicle 102, and the multi-stage telescopic cylinder of the gantry crane 104 is controlled to fall. During the falling process, the piston rod 219 located at the bottom of the four round rods 212 first contacts the inner bottom surface of the battery box 201, and the piston rod 219 moves upward along the inner wall of the sliding sleeve 218 and compresses the spring 222, thereby increasing the pressure inside the sliding sleeve 218. At this time, the gas inside the sliding sleeve 218 is slowly discharged to the outside along the vent hole 221. The contraction of the buffer assembly makes the process of placing the battery block 228 into the rotary groove 210 smoother, reducing vibration and contact with the battery block 228. Collision, when the piston rod 219 moves up to the maximum distance inside the sliding sleeve 218, the torsion column 223 is rotated ninety degrees, and the two support heads 2041 of the support plate 204 are inserted into the corresponding support grooves 209 under the action of the elastic potential energy of the spring 1 205. At this time, the support plate 204 at the same height inside the battery box 201 supports the corresponding battery block 228, and then the multi-stage telescopic cylinder of the gantry crane 104 is retracted until the piston rod 219 leaves the battery box 201. The piston rod 219 moves downward inside the sliding sleeve 218 under the action of the elastic potential energy of the spring 222. The gas outside the sliding sleeve 218 quickly enters the inside of the sliding sleeve 218 from the one-way valve 220, and the cover of the battery box 201 is closed. The elastic rubber pad on the inner wall of the battery box 201 makes the battery block 228 fit tightly with the corresponding elastic electrode 202;

[0058] In this embodiment, the low-power battery replaced from the battery box 201 is placed into the battery box 201 of the charging device in the same manner;

[0059] Embodiment 2, on the basis of embodiment 1, the surface of the connecting plate 229 is symmetrically fixedly connected with the second mounting frame 301, and the gantry crane 104 slides along the slide rail 103, so that the connecting plate 229 on the multi-stage telescopic cylinder of the gantry crane 104 drives one of the mounting frames 1 214 to move to the top of the battery box 201, and the cover of the battery box 201 is opened, so that the support block 211 on the round tube 1 303 is aligned with the direction of the avoidance groove 208, so that the round tube 1 303 with the support block 211, the sliding sleeve 218 and the piston rod 219 along the through groove 207 sequentially string together the battery blocks 228 inside the battery box 201, and the piston rod 219 continues to press down the second mounting frame 301 after touching the bottom surface of the battery box 201, so that the piston rod 219 moves upward inside the sliding sleeve 218, and slides in the process The air pressure inside the sleeve 218 increases, and part of the gas enters the inside of the air box 312 through the air pipe 313, and enters the inside of the arc sleeve 304 through the connecting pipe 311, so that the pressure inside the arc sleeve 304 increases, and then the arc slider 305 moves inside the arc sleeve 304 in the direction away from the arc sleeve 304, and the other part of the gas is slowly discharged to the outside of the sliding sleeve 218 through the air leakage hole 221. During this process, the spring four 309 at the end of the U-shaped slider 308 continuously rolls along the inclined surface of the wedge block 306, and continuously makes the U-shaped slider 308 continuously perform reciprocating motion of the compressed spring five 315 inside the rectangular sleeve 307, until the rectangular sleeve 307 is against one of the limit blocks 310, and at this time, the arc slider 305 rotates ninety degrees around the axis of the round tube 1 303;

[0060] In this embodiment, when the arc-shaped slider 305 slides out of the arc-shaped sliding sleeve 304, the elastic potential energy of the coil spring 314 is increased by the driving force of the rectangular sliding sleeve 307. When the piston rod 219 moves to the maximum position inside the sliding sleeve 218, the arc-shaped slider 305 slides toward the inside of the arc-shaped sliding sleeve 304 under the action of the elastic potential energy of the coil spring 314. During this process, the U-shaped slider 308 will press against the surface of one of the wedge blocks 306 to drive the circular tube 1 303 to rotate until the rectangular sliding sleeve 307 presses against the other limit block 310. At this time, the circular tube 1 303 rotates ninety degrees, that is, the support block 211 on the surface of the circular tube 1 303 rotates ninety degrees. At this time, the battery block 228 can be lifted out of the battery box 201.

[0061] In this embodiment, when the battery is placed in the battery box 201, the piston rod 219 contracts inside the sliding sleeve 218, causing the support block 211 on the surface of the round tube 1 303 to rotate 90 degrees again, thereby facilitating the round tube 1 303 and the support block 211 to be pulled out from the inside of the protective side column 206;
