Description

With the increase in the number of new energy vehicles, the demand for battery replacement is becoming increasingly prominent. During the battery replacement process, a special lifting device is required. The current lifting device usually uses structures such as threaded rods or gear racks. After the car is driven onto the lifting platform, the motor drives the threaded rods or gear racks to drive the lifting platform upward, thereby lifting the car.

[0003] At present, the lifting platform of the lifting device is relatively unstable when it is kept at a high position because of the lack of auxiliary support. If the lifting device is used for a long time and the lubrication work is not in place, the joints and other parts of the device will be severely worn, making the lifting platform relatively unstable when it is at a high position. When the lifting platform is at a high position, if the device is hit and vibrates, since the lifting platform has no other auxiliary support structures except for structures such as threaded rods or gear racks, the vibration will cause the lifting platform to be unstable, thereby affecting the replacement of the car battery.

[0044] Working principle: When in use, the car whose battery is to be replaced is driven from the ramp 6 onto the lifting platform 4. The ramp 6 can facilitate the car to be driven onto the lifting platform 4. The width of the car is assessed according to its model. The distance between the two first lifting plates 5 is adjusted by the adjustment component so that the first lifting plates 5 match the width of the car. The car is parked on the two first lifting plates 5. The first motor 2 is started. The first motor 2 drives the threaded column 3 to rotate. The threaded column 3 drives the lifting platform 4 to move upward. The lifting platform 4 stops when it moves to the specified height. At this time, the support component cooperates with the ramp 6 to support the lifting platform 4 so that the lifting platform 4 can be stably maintained at this height position. The locking component locks the ramp 6. When the lifting platform 4 is lifted up, the lifting platform 4 drives one end of the ramp plate 6 to move upward through the rotating block 7 and the first rotating shaft 8, and the other end of the ramp plate 6 slides on the ground. When the lifting platform 4 rises to a certain height, the ramp plate 6 leaves the ground and hangs in the air. At this time, the anti-plate 9 on the rotating block 7 contacts the bottom of the lifting platform 4. The anti-plate 9 can prevent the ramp plate 6 from rotating excessively and can also prevent the ramp plate 6 from swinging in the air. After the height of the ramp plate 6 is higher than the limit seat 10, the lifting platform 4 is controlled to drive the ramp plate 6 to move down so that the bottom end of the ramp plate 6 is inserted into the limit groove 11 of the limit seat 10, which completely prevents the ramp from falling. When the ramp plate 6 is swung, the ramp plate 6 supports the lifting platform 4 and enhances the stability of the lifting platform 4; when one end of the ramp plate 6 is inserted into the limiting groove 11, one end of the ramp plate 6 will contact the arc surface 1301 of the insert block 13, and the ramp plate 6 will press the two insert blocks 13 into the sliding groove 12 through the arc surface 1301. The first spring 14 is compressed. When the slot 15 is exactly opposite to the insert block 13, under the action of the first spring 14, the insert block 13 is inserted into the slot 15, and the bottom surface 1302 contacts the side wall of the slot 15. The insert block 13 can prevent the ramp plate 6 from leaving the limiting groove 11 and limit the ramp plate 6; when needed, the ramp plate 6 leaves the limiting groove 11, Use the tip of your toes to push the movable plate 23, which pulls one end of the support plate 20 through the connecting line 22, causing the support plate 20 to rotate around the hinge, and the second spring 21 is compressed. Then, step on the pressing plate 19 with your foot, and the pressing plate 19 drives the connecting plate 17 to move downward. The connecting plate 17 pulls the plug 13 through the two connecting ropes 18, inserting the plug 13 into the slide groove 12, so that the plug 13 leaves the slot 15, and the ramp plate 6 can be driven upward by the lifting platform 4 to leave the limit groove 11, so that the foot leaves the pressing plate 19 and the movable plate 23. Under the action of the first spring 14 and the second spring 21, the plug 13, the connecting plate 17, the pressing plate 19 and the support plate 20 are all reset;When the lifting platform 4 drives one end of the ramp plate 6 to rise, the ramp plate 6 drives the rotating block 7 to rotate, and the rotating block 7 drives the curved plate 25 to rotate around the first rotating shaft 8 through the connecting plate 24. The curved plate 25 and the connecting plate 24 enter the avoidance groove 26, and one end of the curved plate 25 will lift the baffle 29 from the rectangular groove 27. The baffle 29 rotates around the second rotating shaft 28. When the abutment plate 9 on the rotating block 7 contacts the bottom of the lifting platform 4, the ramp plate 6 just rotates ninety degrees, and the curved plate 25 rotates ninety degrees to just lift the baffle 29 to a vertical ninety degrees. The baffle 29 is upright to prevent the car from slipping on the lifting platform 4; when the lifting platform 4 drives one end of the ramp plate 6 to rise, the other end of the ramp plate 6 slides on the ground, and it is necessary to To prevent the ramp plate 6 from sliding on the ground for a long time and causing greater wear, during the sliding process of one end of the ramp plate 6, the roller 47 rolls on the ground to reduce the friction between the ramp plate 6 and the ground. When the ramp plate 6 needs to be inserted into the limit groove 11, the inner wall of the limit groove 11 will press the roller 47, pressing the roller 47 into the notch 44, and the third spring 45 is compressed; when it is necessary to adjust the distance between the first lifting plate 5 to adapt to the width of the car, the second motor 33 is started, the second motor 33 drives the fourth shaft 34 to rotate, the fourth shaft 34 drives the second gear 35 to rotate, the second gear 35 drives the first gear 32 to rotate, the first gear 32 drives the third shaft 31 to rotate, and the third shaft 31 drives the first bidirectional threaded rod 30 rotates, the first bidirectional threaded rod 30 drives the two first lifting plates 5 to move in opposite directions at the same time, so as to achieve the purpose of adjusting the distance between the first lifting plates 5; when the first lifting plates 5 are used for a long time, deformation and bending problems will occur, so it is necessary to use the second lifting plate 36 and the first lifting plate 5 alternately to extend the service life of the first lifting plates 5. When replacement is needed, the thickness of the connecting sleeve 42 is set to a unit distance, and the first electric push rod 40 is started. The first electric push rod 40 drives the mounting plate 41, the second motor 33 and the fourth rotating shaft 34 to move two unit distances, so that the second gear 35 is not engaged with the first gear 32, the second gear 35 is engaged with the third gear 39, and the fourth gear 43 is engaged with The first gear 32 is engaged, and starting the second motor 33 simultaneously drives the first gear 32 and the third gear 39 to rotate, causing the first bidirectional threaded rod 30 and the second bidirectional threaded rod 37 to rotate simultaneously, moving the two first lifting plates 5 away from each other and the two second lifting plates 36 toward each other, thereby replacing the first lifting plates 5 with the second lifting plates 36. The electric push rod 40 is then started to drive the second motor 33 back a unit distance, so that the second gear 35 and the third gear 39 are still engaged. The first gear 32 is now aligned with the connecting sleeve 42. At this time, the second motor 33 can independently drive the second bidirectional threaded rod 37 to rotate, thereby adjusting the distance between the two second lifting plates 36.
