[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Pressing plates 9 are fixed on the bottom surfaces of the telescopic ends of the two electric telescopic rods 8, and the pressing plates 9 are arranged above the bottom bed 3. Slide grooves are provided on the bottoms of the opposite back surfaces of the two circular frames 5. The telescopic ends of the two electric telescopic rods 8 are arranged to be synchronized, and a number of rubber strips are fixed on the bottom surface of the pressing plate 9, and the several rubber strips are all set to be soft rubber. A sensor is arranged in the bottom surface of the pressing plate 9, so that the elevator floor door on the transfer and reversing device can stop sliding in time, so as to avoid the elevator floor door on the transfer and reversing device from sliding excessively under the action of inertia and causing steering deviation.

[0030] Z-shaped plates 10 are fixedly installed on both sides of the top surface of the pressure plate 9, and cylinders 11 are penetrated and fixedly installed on the top surfaces of the two Z-shaped plates 10. Slide columns 12 are slidably installed on the inner walls of the two cylinders 11. Springs are arranged between the two slide columns 12 and the two cylinders 11. Short plates are arranged on the bottom surfaces of the two slide columns 12. Rubber rollers 13 are rotatably installed on the bottom opposite surfaces of the short plates of the two slide columns 12. The rubber rollers 13 are arranged above the bottom bed 3 and below the back of the pressure plate 9. The rubber rollers 13 roll tightly against the elevator floor door to slow down the sliding speed of the elevator floor door and avoid the elevator floor door on the transfer and reversing device from sliding too fast, resulting in poor stop effect of the elevator floor door.

[0031] When in use, the elevator floor door on the conveyor belt moves to the bottom bed 3, and the transmission roller 4 on the bottom bed 3 supports the elevator floor door. Under the action of friction, the transmission roller 4 starts to rotate forward. When reversing is required, the steering drive module 2 on the support column 1 is started by electric wires. The servo motor shaft in the steering drive module 2 rotates forward and reverse according to the direction of conversion required. The servo motor shaft drives the bottom bed 3 to turn, and the bottom bed 3 rotates on the protective shell of the steering drive module 2. When the elevator floor door moves to the bottom bed 3, the bottom bed 3 supports the circular frame 5, and the circular frame 5 supports the electric telescopic rod 8. The telescopic end of the electric telescopic rod 8 supports the pressing plate 9. The sensor on the pressing plate 9 senses the elevator floor door, and the sensor uses electric wires to start the electric telescopic rod 8 on the circular frame 5. The electric telescopic rod 8, the telescopic end begins to move downward, the telescopic end of the electric telescopic rod 8 drives the pressure plate 9 to move downward, and the pressure plate 9 drives the rubber strip to move downward. When the elevator floor door on the conveyor belt moves to the bottom bed 3, due to the effect of inertia, the elevator floor door will continue to slide on the transfer and reversing device. Failure to stop the sliding of the elevator floor door in time may easily cause the elevator floor door to deviate during reversing. In the process of the pressure plate 9 driving the rubber strip to move downward, the rubber strip contacts the elevator floor door. Under the effect of the squeezing force, the rubber strip stops the sliding elevator floor door from moving, so that the elevator floor door on the transfer and reversing device can stop sliding in time, preventing the elevator floor door on the transfer and reversing device from sliding excessively, thereby avoiding the problem of steering deviation caused by excessive sliding of the elevator floor door on the transfer and reversing device under the effect of inertia.

[0032] When the retractable end of the electric telescopic rod 8 drives the pressing plate 9 to move downward, the pressing plate 9 drives the Z-shaped plate 10 to move downward, and the Z-shaped plate 10 drives the cylinder 11, and the cylinder 11 drives the sliding column 12 to move downward, and the sliding column 12 drives the rubber roller 13 to move downward. In the process of moving downward, the rubber roller 13 contacts the elevator floor door under the action of friction. When the pressing plate 9 drives the Z-shaped plate 10 to move further downward, the rubber roller 13 presses the elevator floor door down. Under the action of the downward pressure, the rubber roller 13 drives the sliding column 12 to move upward, and the sliding column 12 slides upward in the cylinder 11. Under the action of the spring force of the sliding column 12, the rubber roller 13 rolls tightly against the elevator floor door, slowing down the sliding speed of the elevator floor door and preventing the elevator floor door from sliding too fast on the transfer reversing device, thereby avoiding the problem of poor stop effect of the elevator floor door caused by the elevator floor door sliding too fast on the transfer reversing device.

[0033] See also Figure 1-9 On the basis of the above embodiment, another embodiment of the present invention further includes a guide device 6 and a steering limit device 7, wherein the guide device 6 is arranged on the left and right sides of the bottom bed 3, and the guide device 6 includes two horizontal plates 61, and the horizontal plates 61 are fixed to the bottom of the left and right sides of the bottom bed 3, and the top surfaces of the two horizontal plates 61 are fixed with vertical columns 62, and L-shaped cylinders 63 are fixedly installed on both sides of the bottom surface of the pressure plate 9, and the two vertical columns 62 are slidably installed on the bottom of the inner wall of the L-shaped cylinder 63, and the inner walls of the two L-shaped cylinders 63 are slidably installed with sliding rods 64, and the opposite surfaces of the two sliding rods 64 are fixed with abutment plates 65, and the tops of the outer walls of the two L-shaped cylinders 63 are fixed There are baffles 66, two springs are arranged between the two baffles 66 and the two abutment plates 65, circular holes are opened on the opposite surfaces of the two L-shaped cylinders 63, and sliding rods 64 are slidably installed in the circular holes of the two L-shaped cylinders 63, and round blocks are arranged on the back sides of the two sliding rods 64, and the back sides of the two round blocks are arranged as concave arc surfaces, and the two round blocks are slidably arranged on the inner walls of the two L-shaped cylinders 63, and hydraulic oil is arranged inside the two L-shaped cylinders 63. The abutment plates 65 push the elevator floor door to the middle of the bottom bed 3, so that the elevator floor door is in a straight state, so as to avoid the elevator floor door position on the transfer and reversing device from shifting left and right and causing the elevator floor door to slip when turning and switching.

[0034] The guiding device 6 also includes four semi-arc blocks 67, two semi-arc blocks 67 are fixed on the opposite surfaces of the two abutment plates 65, arc spring sheets 68 are fixed on the opposite surfaces of the four semi-arc blocks 67, and two rubber strips 69 are fixed on one end of the four arc spring sheets 68 away from the four semi-arc blocks 67. The two rubber strips 69 are arranged on the left and right sides of the bottom bed 3. Under the elastic force of the arc spring sheets 68, the rubber strips 69 are slowly attached to the elevator floor door to avoid bumps and damages caused by excessive force when the transfer and reversing device corrects the elevator floor door.

[0035] A steering limit device 7 is provided at the bottom of the outer wall of the guiding device 6, and the steering limit device 7 includes two ring frames 71, the ring frames 71 are fixed at the bottom of the outer walls of the two L-shaped cylinders 63, and rectangular rods 72 are fixed on the inner walls of the two ring frames 71. The two rectangular rods 72 are slidably installed in the slide grooves of the two circular frames 5, and the front sides of the two rectangular rods 72 are hingedly installed with H-shaped frames 73, and the back sides of the two rectangular rods 72 are fixed with U-shaped plates 74. The two U-shaped plates 74 are arranged on the movement tracks of the two H-shaped frames 73, so that the bottom bed 3 remains parallel to the assembly line after reversing, so as to avoid the transfer and reversing device failing to remain parallel to the assembly line during reversing, resulting in poor reversing transmission effect.

[0036] The steering limit device 7 also includes two short cylinders 75, and the short cylinders 75 are fixed on the back sides of the two H-shaped frames 73. The inner walls of the two short cylinders 75 are slidably installed with concave arc blocks 76. Springs are arranged between the two concave arc blocks 76 and the two short cylinders 75. Rubber balls 77 are rotatably installed on the tops of the inner walls of the two concave arc blocks 76. Under the action of the elastic force of the springs of the concave arc blocks 76, the rubber balls 77 are tightly pressed against the bottom of the elevator door to prevent the elevator door from shaking after the transfer and reversing device is reversed, causing damage to the elevator door.

[0037] When the telescopic end of the electric telescopic rod 8 drives the pressure plate 9 to move downward, the horizontal plate 61 supports the vertical column 62, the pressure plate 9 drives the L-shaped cylinder 63 to move downward, the vertical column 62 slides upward in the L-shaped cylinder 63, the hydraulic oil in the L-shaped cylinder 63 is squeezed, the hydraulic oil squeezes the round block of the slide bar 64 in the L-shaped cylinder 63, and the slide bar 64 slides toward the middle in the L-shaped cylinder 63, the slide bar 64 drives the push plate 65 to move toward the middle, the push plate 65 pulls the spring on the baffle 66, and the push plate 65 pushes the elevator door to move toward the middle. When the telescopic end of the electric telescopic rod 8 is reset, the slide bar 64 in the L-shaped cylinder 63 moves downward. , the hydraulic oil in the L-shaped cylinder 63 moves downward, and the spring on the baffle 66 begins to deform under the action of elastic force. The spring on the baffle 66 pulls the abutment plate 65 to the initial position. Due to the different sizes of the elevator floor doors being processed, elevator floor doors of different sizes are prone to cause sliding direction deviation when sliding to the transfer and reversing device. The abutment plate 65 pushes the elevator floor door to the middle of the bottom bed 3, so that the elevator floor door is in a straight state, preventing the elevator floor door from sliding onto the transfer and reversing device and deviating, thereby avoiding the problem of the elevator floor door sliding off during the steering and reversing due to the left and right deviation of the elevator floor door position on the transfer and reversing device.

[0038] While the slide bar 64 drives the butt plate 65 to move toward the middle, the butt plate 65 drives the semi-arc block 67 to move toward the middle, the semi-arc block 67 drives the arc spring piece 68 to move toward the middle, the arc spring piece 68 drives the rubber strip 69 to move toward the middle, the rubber strip 69 contacts the elevator floor door, and the rubber strip 69 pushes the elevator floor door to the middle of the bottom bed 3. The arc spring piece 68 on the rubber strip 69 is deformed under the action of the squeezing force, and under the elastic force of the arc spring piece 68, the rubber strip 69 slowly sticks to the elevator floor door, preventing the transfer and reversing device from pushing the elevator floor door with too much force, thereby avoiding the problem of excessive force when the transfer and reversing device corrects the elevator floor door and causing damage.

[0039] When the pressing plate 9 drives the L-shaped cylinder 63 to move downward, the L-shaped cylinder 63 drives the ring frame 71 to move downward, the ring frame 71 drives the rectangular rod 72 to move downward, the rectangular rod 72 slides downward on the circular frame 5, the rectangular rod 72 drives the U-shaped plate 74 to move downward, and the rectangular rod 72 drives the H-shaped frame 73 to move downward. When the transplanting reversing device is turned by the steering drive module 2, an H-shaped frame 73 contacts the bottom of the assembly line. Under the restriction of the assembly line, an H-shaped frame 73 rotates on the rectangular rod 72. The H-shaped frame 73 rotates onto the bottom bed 3. During the rotation of the bottom bed 3, the other H-shaped frame 73 contacts the H-shaped frame 73 again. The other H-shaped frame 73 is restricted by the U-shaped plate 74 and does not rotate. The other H-shaped frame 73 restricts the bottom bed 3 to keep the bottom bed 3 parallel to the assembly line after the reversal, thereby preventing the transfer and reversing device from loading the elevator floor door and failing to keep parallel to the assembly line when reversing, thereby avoiding the problem of poor reversing transmission effect caused by the transfer and reversing device failing to keep parallel to the assembly line when reversing.

[0040] When the H-shaped frame 73 rotates on the rectangular rod 72, the H-shaped frame 73 drives the short cylinder 75 to rotate, the short cylinder 75 drives the spring to rotate, the spring drives the concave arc block 76 to rotate, the concave arc block 76 drives the rubber ball 77 to rotate, and the rubber ball 77 rotates to the bottom of the elevator door. When the transfer and reversing device reverses for transmission, there is a gap between the transfer and reversing device and the assembly line. The gap can easily cause the elevator door to shake during transmission. When the elevator door moves toward the assembly line after the turn, the spring of the concave arc block 76, under the action of elastic force, allows the rubber ball 77 to press tightly against the bottom of the elevator door, preventing the elevator door from shaking during transmission after the shifting, thereby avoiding the problem of damage to the elevator door caused by the transfer and reversing device after the reversal.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
