[0040] One end of the linkage rod one 218 is fixedly connected with a guide roller one 222. Both ends of the connection block 215 are fixedly connected with guide rollers two 223. A flat rope 224 is wound outside the guide roller one 222 and the guide roller two 223 on the same side.

[0041] During the stage when the long block 217 drives the linkage rod one 218 to rotate, since the guide roller two 223 does not rotate, when the linkage rod one 218 and the guide roller one 222 rotate along the guide roller two 223, the flat rope 224 will rotate along the outside of the guide roller two 223. The flat rope 224 drives the guide roller one 222 to rotate. The guide roller one 222 drives the electric push rod three 219 to rotate through the linkage rod one 218.

[0043] By rotating the linkage rod two 216 through the rotating component, the long block 217 is driven to rotate, and the load-bearing block 21 is driven to move, which is beneficial to adjusting the position of the load-bearing block 21, beneficial to the equipment smoothly crossing the pit on the load-bearing plane during the transfer stage, and expanding the applicable section for the transfer of the LED display equipment.

[0044] The linkage assembly includes a pair of first pipe covers 312 fixedly connected to both sides of the lower head of the bearing block 21 and a flow control component 313 fixedly connected to one end of the bearing block 21. A pair of guiding grooves 314 are reserved in the flow control component 313. A blocking block 315 is slidably connected in the first pipe cover 312. A first connecting rod 316 extending out of the first pipe cover 312 is fixedly connected to the lower wall surface of the blocking block 315. A receiving block 317 is fixedly connected to the lower wall surface of the first connecting rod 316. The upper head of the first pipe cover 312 is connected to a conveying channel 310. The conveying channel 310 is flexible. One end of the conveying channel 310 is connected to the guiding groove 314.

Transmission fluid is filled in both the first pipe cover 312 and the conveying channel 310. A blocking component is arranged in the flow control component 313. The lower wall surfaces of a pair of receiving blocks 317 are both fixedly connected to a leather cover 326;

[0045] Through the installation of the linkage assembly, when the pair of bearing blocks 21 move downward, according to the different heights of the two flat surfaces at both ends of the pit, the heights of the pair of receiving blocks 317 are adapted to change, which is beneficial to keeping the bearing block 21 horizontal when it abuts against both ends of the pit, and is beneficial to the equipment smoothly crossing the pit on the bearing plane during the transfer stage.

[0046] The blocking component includes a second ring block 321 rotatably connected in the flow control component 313 and a second protruding block 324 fixedly connected to the outside of the flow control component 313.

[0050] Transition blocks 24 are rotatably connected to both ends of the bearing block 21. A roller 25 is rotatably connected to one end of the transition block 24;

[0051] The transition block 24 facilitates the device to smoothly climb onto the upper part of the bearing block 21, and facilitates the device to smoothly cross the potholes on the bearing plane via the bearing block 21 during the transfer stage.

[0052] The battery 6 is installed in the supporting platform 2. Two pairs of installation blocks 7 are fixedly connected to the lower part of the supporting platform 2. A first motor 8 is installed at one end of each of the two pairs of installation blocks 7. The output heads of the two pairs of first motors 8 are fixedly connected to the wheels 9. The first motor 8 is electrically connected to the control console 3.

[0053] The first motor 8 controls the rotation of each wheel 9, which facilitates the smooth movement of the transfer device with the LED display screen across the bearing block 21.

[0054] A pair of first protrusions 28 are fixedly connected to the lower part of the bearing block 21. A notch 29 is reserved below the first protrusion 28. Supporting bars 26 are installed at the positions of the bottom of the supporting platform 2 corresponding to the notch 29. Circular blocks 27 are fixedly connected to the edges of the supporting bars 26.

[0055] The notch 29 is sleeved outside the supporting bar 26, and the bearing block 21 is supported by the supporting bar 26, which is conducive to adjusting the position of the bearing block 21. The circular block 27 is conducive to restraining the movement of the first protrusion 28 in one direction and conducive to preventing the bearing block 21 from detaching during the transfer stage of the device.

[0056] The implementation method is specifically as follows: When there is a pit in the bearing plane during the transfer stage of the LED display screen, the device stops at one end of the pit. The console 3 controls the electric drive push rod 214 of a bearing block displacement assembly closer to the pit to shorten, so that the connecting block 215 approaches the supporting table 2. When the gap between the connecting block 215 and the supporting table 2 is the smallest, the connecting block 215 stops moving. The console 3 controls the motor 225 of the bearing block placement and removal assembly to start, causing the linkage rod 226 to rotate. The rotation of the linkage rod 226 causes the first ring block 227 to rotate. The first ring block 227 drives the second linkage rod 216 to rotate. The second linkage rod 216 drives a pair of long blocks 217 to rotate, so that the pair of long blocks 217 rotate to the middle of the upper part close to the supporting table 2, and the grippers of the electric control gripper 210 face the prisms 23 on the bearing block 21. The console 3 controls the two electric drive push rods 219 to extend simultaneously, causing the pair of electric control grippers 210 to move downward, so that the grippers of the pair of electric control grippers 210 respectively extend into a pair of receiving openings 22. Then, the console 3 controls the grippers of the pair of electric control grippers 210 to retract and respectively close to the outside of the prism 23. Then, the console 3 controls the two electric drive push rods 219 to shorten, causing the pair of electric control grippers 210 and the pair of bearing blocks 21 to move upward. The console 3 controls the output head of the motor 225 to rotate counterclockwise, causing the pair of long blocks 217 to rotate counterclockwise, so that the pair of long blocks 217 rotate to the front of the supporting table 2. The long blocks 217 are horizontal. The console 3 controls the electric drive push rod 214 to extend, causing the connecting block 215 to push forward, so that the bearing block 21 pushes forward. The console 3 controls the two electric drive push rods 219 to extend, causing the pair of electric control grippers 210 and the pair of bearing blocks 21 to move downward, pressing the pair of bearing blocks 21 against both ends of the pit. The console 3 controls the grippers of the pair of electric control grippers 210 to release the pair of bearing blocks 21. The console 3 controls the two pairs of motors 8 of the device to rotate the two pairs of wheels 9, so that the device smoothly crosses the pit through the pair of bearing blocks 21, expanding the applicable road sections for the transfer of the LED display screen by the device;

[0057] During the stage when the long block 217 drives the first linkage rod 218 to rotate, since the second guide roller 223 does not rotate, during the stage when the first linkage rod 218 and the first guide roller 222 rotate along the second guide roller 223, the flat rope 224 will rotate along the outside of the second guide roller 223. The flat rope 224 drives the first guide roller 222 to rotate. The first guide roller 222 drives the electric drive push rod 219 to rotate through the first linkage rod 218. Through the long block 217, the electric drive push rod 219 is maintained in a vertical state, which is beneficial to keeping the lower bearing block 21 horizontal, beneficial to keeping the bearing block 21 horizontal when it abuts against both ends of the pit, and beneficial to the device smoothly crossing the pit on the bearing plane during the transfer stage;

[0058] After the transfer equipment passes over the pit via the bearing block 21, the bearing block shifting assembly and the bearing block placing assembly at the rear are operated to bring the pair of bearing blocks 21 on the pit to the top of the equipment. A protrusion 28 is installed under the pair of bearing blocks 21, and a recess 29 is installed at one end of the protrusion 28. The recess 29 is sleeved on the outside of the supporting rod 26, and the bearing block 21 is supported by the supporting rod 26, which is conducive to adjusting the position of the bearing block 21. The round block 27 is conducive to preventing the protrusion 28 from moving to one end, which is conducive to preventing the bearing block 21 from detaching during the equipment transfer stage.

[0059] When the pair of electric drive push rods 219 move the pair of bearing blocks 21 to the bottom, the pair of bearing blocks 21 maintain a horizontal shape. When the planes at both ends of the pit have different heights, the receiving blocks 317 at both ends of a bearing block 21 are successively abutted against the planes at both ends of the pit. When the receiving block 317 on one side abuts against the high plane at one end of the pit, the receiving block 317 on the other side does not abut against the plane at one end of the pit. The bearing block 21 still maintains a horizontal shape and moves to the bottom. The receiving block 317 abutting against the plane at one end of the pit will be pushed to the top by the plane, so that the connecting rod 317 16 and the blocking block 315 move upward, the blocking block 315 squeezes the transmission fluid in the pipe cover 1 312 into the delivery channel 310, the transmission fluid is introduced into the opposite guide groove 314 and the delivery channel 310 through the delivery channel 310 and the opposite guide groove 314 and the delivery channel 322, and is introduced into the opposite pipe cover 1 312 through the opposite delivery channel 310, the transmission fluid in the opposite pipe cover 1 312 presses the blocking block 315 and the connecting rod 1 316 to the bottom, so that the receiving block 317 that has not yet abutted against the flat surface of the pit is abutted against the flat surface, After the receiving blocks 317 are all in contact with the plane, the plane exerts the same thrust on the pair of receiving blocks 317, and the transmission fluid in the pair of pipe covers 1 312, the pair of conveying paths 310, the pair of guide grooves 314 and the conveying groove 322 no longer moves. The electric drive push rod 2 325 of the blocking assembly is controlled by the operating console 3 to shorten the traction linkage block 323 and rotate it at a right angle. The linkage block 323 pulls the ring block 2 321 to rotate at a right angle. The ring block 2 321 pulls the conveying groove 322 inside to rotate at a right angle to a vertical state, and the two ends of the conveying groove 322 are not aligned with the pair of guide grooves 314. When the transmission fluid in the pair of pipe covers 312 and the conveying channel 310 at both ends cannot be guided back and forth, so that the pair of blocking blocks 315 and the connecting rod 316 at both ends cannot move to the top or bottom, so that the pair of receiving blocks 317 are in contact with the planes on both sides of the pit and maintain the horizontal state of the bearing block 21. The transition blocks 24 at both ends of the bearing block 21 are in contact with the planes, which is conducive to maintaining the horizontal state of the bearing block 21 when the planes at both ends of the pit are of different heights, and is conducive to the equipment to smoothly pass over the pit of the bearing plane through the bearing block 21 during the transportation stage;

[0060] The upper wall surfaces of a pair of receiving blocks 317 are fixedly connected to a pair of arranged connecting rods two 318. The side wall surfaces of the connecting rods two 318 are slidably connected to pipe covers two 319. The upper wall surfaces of the pipe covers two 319 are fixedly connected to the lower wall surfaces of the bearing blocks 21. Through the pipe covers two 319 and the connecting rods two 318 at both ends, it is beneficial to inhibit and prevent the receiving blocks 317 from being deflected, and it is beneficial for the receiving blocks 317 to support the bearing blocks 21.
