the mounting frame 22 and the multi-groove sliding rail 27 are both provided with corner line positions of the steel structure 11, and the double-steel laminated glass 34 with good light transmission is matched, so that the shielding of an elevator to light can be reduced;
the hollow structure of the balancing weight 19 can increase the length (height) for ensuring the weight of the balancing weight, and can avoid large-area shielding of light.
When the car 13 moves downwards, the double-head air cylinders 18 on the lower side are started to control the piston rods 17 on the two ends of the double-head air cylinders to extend out, and the mounting plate 30 is driven to move through the connecting rods 29; the movement of the mounting plate 30 changes the state of the privacy protection mechanism, and only one shielding assembly works at the same moment for two shielding assemblies belonging to the same privacy protection mechanism, so that the corresponding shielding cloth 15 is forced to stretch for protecting privacy, and the two shielding assemblies are specific: the mounting plate 30 drives the mounting box 20 to move together, the telescopic rod 42 and the storage box 21 move together along with the mounting box 20, so that the friction wheel 28 contacts the side surface of the elevator shaft, the elevator car 13 moves downwards at the moment and directly drives the mounting box 20 to move downwards, the storage box 21 is disturbed due to the friction between the friction wheel 28 and the side surface of the elevator shaft, the coil spring 38 in a winding state is continuously forced to rotate, the height difference is generated between the mounting box 20 and the storage box 21, the moving speed of the storage box 21 is smaller than that of the mounting box 20 until the shielding cloth 15 is completely pulled out, at the moment, the two side surfaces of the elevator car 13 are completely shielded by the shielding cloth 15, and people in the elevator car 13 cannot see the condition of other floor households through the double-steel laminated glass 34 with good light transmittance degree when going downstairs;
when the car 13 moves upwards, the double-head air cylinder 18 on the upper side is started to control the piston rods 17 at the two ends of the double-head air cylinder to extend, and the connecting rod 29 drives the mounting plate 30 to move, so that the principle is the same as that described above: the mounting plate 30 drives the mounting box 20 to move together, the telescopic rod 42 and the storage box 21 move together along with the mounting box 20, so that the friction wheels 28 contact the side surface of the elevator shaft, at the moment, the car 13 moves upwards, the mounting box 20 is directly driven to move upwards, the storage box 21 is disturbed due to the friction between the friction wheels 28 and the side surface of the elevator shaft, the coil spring 38 in a winding state is continuously forced to rotate, the height difference is generated between the mounting box 20 and the storage box 21, the moving speed of the storage box 21 is smaller than that of the mounting box 20 until the shielding cloth 15 is completely pulled out, at the moment, the two side surfaces of the car 13 are completely shielded by the shielding cloth 15, namely, the privacy protection mechanism is switched into an unfolding mode, and people in the car 13 cannot watch the condition in other floor households through the double-steel laminated glass 34 with good light transmittance degree when going upstairs;
whether the car 13 is raised or lowered, only one double-headed cylinder 18 is activated, its corresponding shutter assembly (left and right, i.e. the two shutters at the top of the car 13 or the two shutters at the bottom) moves away from the car 13, and as the car 13 moves, the moved shutter assembly will pull apart (the shutter 15 is pulled apart completely), at which time only the moved shutter assembly is visible from the outside of the hoistway, with the non-moved shutter assembly being located between the car 13 and the already moved shutter assembly.
When the elevator car 13 is not used by people, the elevator car can automatically stop at the middle floor according to reasonable programming of the PLC, the balancing weight 19 and the elevator car stop at the same height, light rays of the floor need to pass through more glass (the periphery of the elevator car 13 is also made of toughened glass), and other floors can be easily transparent;
when the car 13 is in a stopped state (including temporary stop when reaching a destination floor), the double-headed cylinder 18 (regardless of whether the double-headed cylinder 18 on the upper and lower sides) controls the mounting plate 30 to retract, at this time, the storage box 21 disappears due to friction between the friction wheel 28 and the side surface of the elevator shaft, the shielding cloth 15 is rewound on the rotating shaft 23 under the action of the coil spring 38, the storage box 21 is forced to approach the mounting box 20, and the shielding cloth 15 is in a wound state, that is, the privacy structure is switched to the storage mode, and light is not shielded.
In the present invention, the principle that the storage case 21 moves relative to the mounting case 20 is as follows: in any shielding assembly of the invention, the friction wheel 28 and the storage box 21 are in a rotation connection relationship, the connection part of the two is provided with a bearing (a customized bearing), friction exists between the bearing and the shaft (the use requirement is met by selecting proper bearings and selecting different friction coefficients), so that the upper limit of the rotation speed of the friction wheel 28 exists, and the highest rotation speed of the friction wheel 28 can be easily obtained through the material taking of the bearings; when the car 13 moves in an accelerating way (ascends or descends), the mounting plate 30 drives the mounting box 20 to move, and the storage box 21 and the mounting box 20 move in the horizontal direction all the time under the action of the telescopic rod 42; when the storage box 21 and the mounting box 20 contact the inner wall of the elevator shaft, the movement in the horizontal direction is stopped (namely, the double-end air cylinder 18 controls the piston rod of the double-end air cylinder to stop moving), and the storage box 21 and the mounting box 20 are in smooth contact with the inner wall of the elevator shaft (friction exists but is smaller), but at the moment, the friction wheel 28 is also in contact with the inner wall of the elevator shaft, the surface of the friction wheel 28 is rough (friction exists, the static friction force is larger, and the sliding friction force is far smaller than the static friction force); the mounting box 20 having no degree of freedom in the vertical direction with the elevator car 13 always keeps up-and-down movement in synchronization with the car 13, but the storage box 21 has a degree of freedom in the vertical direction with respect to the mounting box 20 and the car 13 by the telescopic rod 42, so that up-and-down movement of the storage box 21 is allowed out of synchronization with the car 13;
the friction wheel 28 is essentially a part of the storage box 21, the friction wheel 28 and the storage box 21 cannot move relatively, and the gravity and the friction force of the friction wheel 28 are calculated together;
the expansion link 42 consumes the pulling force or the pressure applied to the expansion link 42 during the stretching or shrinking process, and the expansion link 42 can transmit the pressure or the pulling force without loss (neglecting the gravity of the expansion link itself) when in the fully-stored state or the fully-stretched state;
the coil spring 38 is wound in a direction such that the housing case 21 and the mounting case 20 of the same shutter member tend to approach each other;
when the car 13 moves from the higher floor to the lower floor, the state of the car 13 sequentially passes: the lower shielding component operates during the process of resting, accelerating and descending, uniform descending, decelerating and descending, and the upper shielding component keeps the corresponding shielding cloth 15 in a storage state under the action of the coil spring 38 no matter whether accelerating or decelerating.
One of the shielding assemblies on the lower side:
the mounting box 20 receives the supporting force of the car 13, which is equal to the sum of the pressure it receives (the weight of the storage box 21) and its own weight; the receiving box 21 receives the supporting force of the mounting box 20, which is equal to the sum of the pulling force of the coil spring 38 and its own weight;
when the car 13 descends in an acceleration manner, the mounting box 20 descends in an acceleration manner, and the resultant force applied to the mounting box 20 is downward: the mounting box 20 receives a tensile force of the car 13, which is greater than the sum of the frictional force received by the mounting box, the self-weight force thereof and the tensile force received by the mounting box (the tensile force generated by the coil spring 38 to the mounting box 20 through the shielding cloth 15); the storage box 21 is firstly static, and the resultant force received by the storage box 21 is zero: the receiving box 21 receives a frictional force equal to the sum of its own weight and the tension of the coil spring 38; after the shielding cloth 15 is fully unfolded, the storage box 21 accelerates and descends along with the car 13, and the storage box 21 receives a resultant force downward: the sum of the tensile force applied to the storage box 21 (the tensile force applied to the storage box by the mounting box 20 through the telescopic rod 42), the self gravity thereof and the tensile force of the coil spring 38 is greater than the friction force applied thereto;
when the car 13 moves at a uniform speed, the resultant force received by the mounting box 20 and the storage box 21 is zero, the relative positions are unchanged, the storage box 21, the mounting box 20, the shielding cloth 15 and the telescopic rod 42 are regarded as a whole, and the friction force received by the whole part is equal to the sum of the gravity of the whole part and the tensile force of the car 13 (the tensile force of the uniform speed movement is smaller than the tensile force of the acceleration descending); if analyzed alone: the mounting box 20 receives the tensile force of the car 13 and its own weight, which is equal to the sum of the tensile force (including the tensile force of the coil spring 38 and the tensile force of the storage box 21 to it) and the frictional force; the tensile force exerted by the storage case 21 (including the tensile force of the coil spring 38 and the tensile force of the mounting case 20 against it) and its own weight are equal to the frictional force exerted by it.
When the car 13 moves in a decelerating manner, the resultant force applied to the mounting box 20 is upward, the mounting box 20 is subjected to the tensile force of the car 13, which is smaller than the sum of the friction force applied to the mounting box and the gravity of the mounting box (the tensile force of the coil spring 38 to the mounting box 20 through the shielding cloth 15); the containing box 21 receives the resultant force upwards, the containing box 21 loses the tension of the mounting box 20 to the resultant force when the resultant force received by the mounting box 20 changes, and the telescopic rod 42 is contracted and internally consumed, so that the containing box 21 receives the tension of the coil spring 38 and the gravity of the containing box, and the friction force (dynamic friction) of the containing box is smaller than that of the containing box; the deceleration of the mounting case 20 and the storage case 21 is synchronized;
when the car 13 is stationary again, the resultant force applied to the mounting box 20 is zero, and the sum of the supporting force applied to the mounting box 20 by the car 13 and the friction force applied to the mounting box is equal to the sum of the self gravity; the resultant force applied to the storage case 21 becomes zero first, and the frictional force (static friction) applied to the storage case 21 is equal to the sum of the gravity of the storage case and the tension of the coil spring 38, and at this time, the storage case 21 is temporarily stationary; then, because the storage box 21 and the inner wall of the elevator shaft do not move relatively, the friction wheel on the storage box 21 can rotate, the friction force between the storage box 21 and the inner wall of the elevator shaft is reduced (the rolling friction is far smaller than the sliding friction), at the moment, the friction force born by the storage box 21 is smaller than the sum of the gravity of the storage box and the pulling force of the coil spring 38, and the resultant force born by the storage box 21 is downward; until the receiving box 21 is close to the mounting box 20, the resultant force applied to the receiving box 21 becomes zero, and the receiving box 21 receives the supporting force of the mounting box 20, which is equal to the sum of the pulling force of the coil spring 38 and its own weight.
The upper shielding assembly is the same as the principle above, namely, by using whether the friction wheel 28 and the inner wall of the elevator shaft have relative movement or not and corresponding sliding friction and rolling friction respectively, when the coil spring 38 with a specific elastic coefficient is arranged, the storage box 21 can keep the state of the principle mounting box 20 when the elevator car 13 moves, and when the elevator car 13 is stationary, the storage box 21 can be close to the mounting box 20; in particular, if the above principle is not considered, the above principle can be bypassed, the unfolding and storage of the shielding cloth 15 can be realized just like the electric control telescopic rod 42, and the two states of the privacy protection mechanism can be switched as well, in addition, when the friction wheel 28 moves relative to the inner wall of the elevator shaft in a non-rolling way, the thrust of the double-head cylinder 18 is in direct proportion to the sliding friction force born by the friction wheel 28, so that the friction force between the friction wheel 28 and the inner wall of the elevator shaft can be changed by changing the output size of the double-head cylinder 18, and the shielding cloth 15 can not be retracted in the speed reduction, speed reduction or uniform speed stage of the elevator car 13.
