Working principle:
the first step: the building site needs to use elevator to transport goods, thereby start traction mechanism 307 and make car mechanism 1 berth at corresponding floor through traction of traction rope 308, the upper surface of bottom plate 101 is parallel with floor surface this moment, the upper surface of bridge plate one 202 is parallel and simultaneously with bottom plate 101 and joint board 402, the one end that bottom plate 101 was kept away from to bridge plate two 203 is buckled and is contradicted in the below position of joint board 402, the workman carries the goods dolly and can go into the building floor smoothly through bridge plate one 202 and joint board 402 this moment, and when pushing down bridge plate one 202 this moment, through bridge plate two 203 and joint board 402's conflict, speed limiting mechanism 2 can not take place the motion, thereby accomplish bridging between car mechanism 1 and joint layer mechanism 4 and the building floor through speed limiting mechanism 2, avoid the problem of gap joint wheel between car mechanism 1 and the building floor, more convenient and fast when making the workman transport goods.
And a second step of: during normal transportation of the car mechanism 1, when the bridge plate two 203 or the bridge plate one 202 contacts the connecting plate 402, the drum 201 can rotate for one hundred eighty degrees, so that the bridge plate one 202 and the bridge plate two 203 are reversed, and the car mechanism 1 is matched with the movement of the car mechanism 1, so that the car mechanism 1 can freely run, when an elevator falls, the passing frequency between the car mechanism 1 and a building floor can be greatly increased in unit time, and the bridge plate one 202 and the bridge plate two 203 can be quickly overturned, in this case, the turntable 205 can also be quickly rotated, the fluid bin 206 is driven to quickly rotate, the side frame 209 can drive the runner 211 to slide in the annular groove 213, the center of the outer ring 212 is positioned above the center of the turntable 205, so that the side frame 209 is limited in the rotating process by the outer ring 212, so that the bin plug 207 needs to be continuously moved in the interior of the fluid bin 206 to adapt to the rotation of the car mechanism, but when the rotation speed is too fast, the non-fluid in the fluid bin 206 can be limited to move the bin plug 207, so that the car mechanism 2 stops or the falling speed limiting mechanism 1 is quickly carried out in the falling process of the car mechanism 1.
And a third step of: through the existence of the non-Newtonian fluid in the fluid bin 206, the car mechanism 1 is not blocked when falling, and after the car mechanism 1 is decelerated under the movement limitation of the bin plug 207, the car mechanism 1 is automatically lowered, so that the car mechanism 1 can be gradually lowered to a layer at a lower speed, workers and cargoes in the car mechanism 1 can be helped to safely fall to the ground when dangers occur, and the use safety of the elevator is improved.
Fourth step: through the setups of standing groove 102 to and at the in-process that car mechanism 1 operated, bridge plate one 202 and bridge plate two 203 can overturn all the time, thereby make the marginal portion of bottom plate 101 be unable to stand, thereby make accommodation space in the elevator narrow, avoid work to bring can crowded then crowded idea get into car mechanism 1, cause car mechanism 1 overload, the load number of restriction car mechanism 1 that can be better guarantees the operation safety of elevator.
Fifth step: through the design of the landing mechanism 4 and the cooperation with the speed limiting mechanism 2, the position that car mechanism 1 stopped at every turn can all make bridge plate one 202 flush with the surface of the connecting plate 402, when the clearance exists between bridge plate one 202 and the connecting plate 402 after car mechanism 1 stops moving, the problem of stopping of the elevator can be definitely found, thereby the problem of the elevator can be comparatively intuitively found by the workman, early warning is made, and the accident rate of the elevator can be greatly reduced.
Sixth step: through the design of buffer gear 5, under the state that elevator normally transported, bellows 501 can follow the lift of car mechanism 1 and breathe in and follow the decline of car mechanism 1 through air leakage valve 504 gas leakage, but when the elevator descends rapidly, the gas leakage rate of air leakage valve 504 can not catch up with the decline rate of car mechanism 1 and then can make bellows 501 and the gaseous deposit in the air sac 503 for bellows 501 and air sac 503 expand in step, cushion the elevator that descends, guarantee the security that inside personnel and goods of car mechanism 1, further improve the security that the elevator born.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
