The working principle is as follows:
the first step is as follows: the elevator is needed to be used for transporting goods in a building site, the traction mechanism 307 is started to enable the car mechanism 1 to stop at a corresponding floor through traction of the traction rope 308, at the moment, the upper surface of the bottom plate 101 is parallel to the floor surface of the floor, at the moment, the upper surface of the first bridge plate 202 is parallel to the upper surface of the bottom plate 101 and is in butt joint with the bottom plate 101 and the connecting plate 402 at the same time, one end, away from the bottom plate 101, of the second bridge plate 203 is bent and abutted to the lower position of the connecting plate 402, at the moment, a worker carries a goods trolley to smoothly enter a building floor through the first bridge plate 202 and the connecting plate 402, when the first bridge plate 202 is pressed downwards, the second bridge plate 203 is abutted to the connecting plate 402, the speed limiting mechanism 2 cannot move, bridging between the car mechanism 1, the connecting mechanism 4 and the building floor is completed through the speed limiting mechanism 2, the problem that wheels are clamped in a gap between the car mechanism 1 and the building floor is solved, and the worker can transport goods more conveniently and quickly.
The second step is that: when the car mechanism 1 is normally transported, when the bridge plate two 203 or the bridge plate one 202 contacts the connecting plate 402, the rotating cylinder 201 can be rotated by one hundred eighty degrees, so that the bridge plate one 202 and the bridge plate two 203 are reversed, and the car mechanism 1 can freely run by matching the motion of the car mechanism 1, when the 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 rapidly turned over, in this case, the rotating disc 205 can also rapidly rotate to drive the fluid chamber 206 to rapidly rotate, so that the side frame 209 drives the rotating wheel 211 to slide in the annular groove 213, because the center of the outer ring 212 is positioned above the center of the rotating disc 205, the side frame 209 is limited by the outer ring 212 in the rotating process, so that the chamber plug 207 needs to continuously move in the fluid chamber 206 to adapt to the rotation, but when the rotating speed is too fast, the non-newtonian fluid in the fluid chamber 206 can limit the movement of the chamber plug 207, so that the mechanism 2 or the speed of the falling mechanism is limited, so that the speed of the car mechanism 1 can be reduced, and the falling speed limiting device can be reduced.
The third step: through the existence of the non-Newtonian fluid in the fluid chamber 206, the clamping is not moved when the car mechanism 1 falls, after the car mechanism 1 decelerates under the movement limitation of the chamber plug 207, the car mechanism 1 can still automatically descend, so that the car mechanism 1 gradually descends to one floor at a lower speed, workers and goods in the car mechanism 1 can safely fall to the ground when danger occurs, and the use safety of the elevator is improved.
The fourth step: through the arrangement of the station slot 102 and in the operation process of the car mechanism 1, the first bridge plate 202 and the second bridge plate 203 can be always turned over, so that the edge part of the bottom plate 101 cannot stand, the accommodating space in the elevator is reduced, the phenomenon that the elevator mechanism 1 is overloaded due to the fact that the elevator mechanism can enter the car mechanism 1 in a squeezing mode with the squeezing idea is avoided, the number of people on the load of the car mechanism 1 can be better limited, and the operation safety of the elevator is guaranteed.
The fifth step: through the design of the layer connecting mechanism 4 and the cooperation with the speed limiting mechanism 2, the position that the car mechanism 1 stops at every turn can make the first bridge plate 202 flush with the fishplate bar 402 surface, when the car mechanism 1 stops moving and finds that there is a clearance between the first bridge plate 202 and the fishplate bar 402, the stopping problem of the elevator can be made clear and definite, so that the worker can find the problem of the elevator more intuitively, early warning is made, and the accident rate of the elevator can be greatly reduced.
And a sixth step: through buffer gear 5's design, under the state of elevator normal transportation, bellows 501 can follow the rising of car mechanism 1 and inhale and follow the decline of car mechanism 1 and pass through air leak valve 504 gas leakage, but when the elevator descends rapidly, the gas leakage speed of air leak valve 504 can not catch up with the falling speed of car mechanism 1 then can make bellows 501 and gasbag 503 in the gas retention, make bellows 501 and gasbag 503 synchronous inflation, cushion the elevator that descends, guarantee the safety of the inside personnel of car mechanism 1 and goods, further improve the security that the elevator bore.
