mutual interlock of the worm 302 and the worm gear 303, thus can effectively avoid the car 204 from falling down, use more safety, when the car 204 goes up and down, draw the lubricating oil stored in the oil storage tank 401 through controlling the electric hydraulic oil pump 402, and spray the lubricating oil on the surface of the rack 203 through the spray gun 403, can play a lubricating effect to the surfaces of the worm gear 303 and the rack 203 through spraying the lubricating oil, reduce the friction between the worm gear 303 and the rack 203, promote the life of the worm gear 303 and the rack 203, while rising, can make the lubricating oil be smeared on the surface of the rack 203 more evenly through the oil brush, the top of the car 204 is connected with a compensation chain 501, the other end of the compensation chain 501 is connected with a balancing weight block 502 through the guide of a guide wheel 5, the car 204 is balanced through the balancing weight block 502 when lifting, the load of the car 204 on the driving device 3 can be reduced when lifting, the labor is saved when lifting, the service life of the driving device 3 can be prolonged, wherein when the balancing weight block 502 is lifted in the inner cavities of a first lifting frame 2 and a second lifting frame 201, the balancing weight block 502 is supported through a limit wheel 503 and is matched with a guide rail 504 through the limit wheel 503, the balancing weight block 502 can be effectively prevented from shaking when lifting, the stability of the lifter during working can be effectively improved, the safety coefficient of use is improved, when the car 204 is lowered to the bottom, the car 204 is supported through a hydraulic spring buffer 601, and the impact force of the car when the car 204 is contacted with the ground can be reduced, the comfort of the elevator in use is improved, when a worker stands in the rubber box, the horizontal condition of the car 204 can be observed through bubbles on the level gauge 7, the standing position is automatically adjusted according to the bubble indication of the level gauge 7, the car 204 is in a horizontal state when ascending or descending, so that the safety of the elevator in work can be further improved, the first box door 702 is movably connected with the inner cavity of the first sliding groove 701, the first box door 702 automatically slides down under the action of gravity after the car 204 ascends, one end of the car 204 can be sealed through the first box door 702, after the car 204 descends, the first box door 702 is supported through the ground, so that the first box door 702 is opened, the first box door 702 cannot be opened in the lifting process, the work operation and use can be effectively avoided, the falling accident occurs, the use is safer, and when the box door at the other end of the car 204 is opened, because the two ends of the top of the other side surface of the car 204 are both welded with the second sliding groove 703, the inner cavity of the second sliding groove 703 is connected with the second car door 704 in a sliding way, the bottom of the second car door 704 is movably provided with the third car door 706, the bottom of the third car door 706 is connected with the bottom of the car 204 through a rotating shaft, the top of one end of the car 204 is provided with the second guide wheel 705 through a bracket, the surface of the second guide wheel 705 is movably provided with a rope, and the two ends of the rope are respectively connected with the tops of the second car door 704 and the third car door 706, when the second car door 704 is lifted, the third car door 706 can be automatically opened under the action of gravity, and the third car door 706 is connected with the safety channel in a superposition way, thereby effectively avoiding the falling accident of workers after the safety channel is damaged, ensuring safer use, closing the second car door 704, and driving one end of the third car door 706, the second door 704 and the third door 706 close the other end of the car 204, so that the use is safer and more convenient, the ascending height of the car 204 can be limited by the limiting rod 8, and equipment on the top of the car 204 is prevented from impacting the cross frame 202.
