[0031] The inner wall of the movable groove 484 is provided with an inclined groove 485, the outer side of the vertical plate 493 is fixedly connected with a slide bar 494, the slide bar 494 is slidably connected inside the inclined groove 485, and the upper surface of the storage plate 4 is fixedly connected with a protective plate 483, which is arranged outside the movable groove 484. With the cooperation of the inclined groove 485 and the slide bar 494, the movement of the vertical plate 493 is guided, and the protective plate 483 is used to block the material to prevent the pressure rake 482 from being unable to flip normally due to the squeezing of the material.

[0032] Specifically, when it is necessary to adjust the maximum lifting height, the electromagnet A234 is energized, and the magnetic repulsion between the electromagnet A234 and the magnet A233 is utilized to insert the magnet A233 into the docking groove on the inner wall of the sleeve A23, thereby realizing the connection between the sleeve A23 and the connecting roller 232. Then, the motor 21 is turned on to drive the rotating shaft 22 to rotate counterclockwise. Under the connection between the sleeve A23 and the connecting roller 232, the main gear 231 is driven to rotate counterclockwise, thereby driving the two sets of sub-gears A241 to rotate clockwise, and under the transmission action of the belt 26, the sub-gear B251 is driven to rotate clockwise, thereby driving the rack plate 271 and the lifting plate 27 to move upward, and the cross plate 28 moves upward accordingly, thereby driving the fixed pulley roller 283. Move up. During the upward movement of the lifting plate 27, the slider A291 and the slider B292 slide in the lifting groove 121 and the inner groove 122 respectively to ensure the stability of the upward movement. When the lifting plate 27 reaches a predetermined height, the electromagnet B124 is energized. Under the action of magnetic attraction, the positioning magnet 295 is inserted into the positioning groove 123 to fix the lifting plate 27. When adjustment is required, the electromagnet B124 is powered off. The positioning magnet 295 shrinks back into the shrinking groove A293 under the action of the restoring force of the spring member A294. At this time, the lifting plate 27 can move up and down normally. During the adjustment process, the wire rope is released as the fixed pulley roller 283 moves upward, thereby achieving a more convenient adjustment of the maximum lifting height according to actual needs. The rotating rod A282 is rotatably connected with the fixed frame 281 to reduce friction during the transmission process. In the process of lifting or lowering materials, the steel wire rope drives the fixed pulley roller 283 to rotate, and then drives the inner magnetic block 2831 to rotate. The magnetic repulsion between the inner magnetic block 2831 and the magnetic block C341 drives the sealing plate 34 to move upward, and the sealing plate 34 is used to squeeze the lubricating oil inside the inner box 32. The lubricating oil is sprayed out through the one-way pressure valve A342, so as to achieve the effect of lubricating the steel wire rope during the wire release and lifting process to reduce friction. When the inner magnetic block 2831 is away from the magnetic block C341, the sealing plate 34 is at the spring member C33. Under the action of reset, the inner box 32 is under negative pressure, and the lubricating oil in the oil storage box 31 is added into the inner box 32 through the one-way pressure valve B351 and the guide pipe 35. The box plug 36 is used to seal the oil storage box 31 and the inner box 32 to ensure the sealing of the oil storage box 31 and the inner box 32 during the operation. At the same time, during the rotation of the fixed pulley roller 283, the inner magnetic block 2831 is used to attract the magnetic block B288 to drive the pressure plate 287 to approach the fixed pulley roller 283, and the brush 289 is used to brush the sprayed lubricating oil evenly, so as to reduce the friction between the wire rope and the fixed pulley roller 283, and play a protective role and ensure the lifting stability. In addition, during the up and down movement of the storage board 4, the limiting short block B44 cooperates with the limiting vertical plate 12 to limit the movement of the storage board 4. When the worker assembles the material, the plug plate 42 contacts the surface of the base 1 and lifts the partition plate A43. The worker can put the material between the partition plate A43 and the storage board 4. During the rising process of the storage board 4, the plug plate 42 and the partition plate A43 remain stationary and are in a descending state relative to the storage board 4 until the limiting short block A41 fits with the bottom surface of the partition plate A43, and the partition plate A43 is used to protect one side of the storage board 4. The partition plate B473 protects the storage board 4 in the initial state. One side is protected. As the storage plate 4 rises and is about to reach a predetermined height, the top rod 474 contacts the bottom surface of the baffle 13, thereby squeezing the spring rod 472 and compressing the partition plate B473 inside the storage box 471. Workers on the upper floors here can directly take out the goods. During the rising process, the gravity of the counterweight block 495 is used to drive the vertical plate 493 and the sleeve B492 to move downward, thereby driving the short shaft 491 and the pressure rake 482 to flip downward, thereby achieving the effect of pressing the material from both sides to prevent the material from falling, and finally achieving the purpose of facilitating the adjustment of the lifting height and ensuring the stable transportation of materials during the lifting process.
