DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] See also Figure 1~Figure 3 The present invention provides an anti-falling elevator system, which includes an elevator shaft 1, a driving mechanism for dragging the elevator car to move is arranged on the top of the elevator shaft 1, and the driving mechanism is driven to rotate by a rotating motor, so as to ensure that the driving mechanism drives the car inside the elevator shaft 1 to move and rise inside the elevator shaft 1; the driving mechanism includes: a guide wheel 3 rotatably connected to the top of the elevator shaft 1, a dragging rope body is sleeved on the winding groove 36 outside the guide wheel 3, one end of the dragging rope body is connected to the car, and the other end is connected to the guide wheel 3, so as to ensure that the guide wheel 3 is driven to rotate by the rotation of the driving motor, so as to control the lifting and falling of the car inside the elevator shaft 1; an anti-falling component, the anti-falling component includes a filling space 21 arranged at the top of the elevator shaft 1 and filled with a non-Newtonian fluid 6, and a non-Newtonian fluid is arranged on the top of the elevator shaft 1. The Newtonian fluid 6 protects the state of the car through the characteristics of the non-Newtonian fluid 6 itself, and prevents the car from rapid movement and rapid changes in speed. The rotating shaft of the guide wheel 3 is rotatably connected to the inside of the filling space 21, and a sealing disk 31 for sealing the filling space 21 is fixed to the outside of the rotating shaft. An adjusting member 4 is slidably connected to the sealing disk 31, and the adjusting member 4 slides on the sealing disk 31 to control the position of the adjusting member 4 deep into the filling space 21. The adjusting member 4 adjusts the resistance between the rotating shaft and the non-Newtonian fluid 6, thereby adjusting the resistance encountered by the adjusting member 4 through the depth of the position inserted into the non-Newtonian fluid 6, thereby controlling the resistance encountered by the guide wheel 3, and controlling and adjusting the moving speed of the car.

[0026] See also Figure 5 and Figure 6 Preferably, the sealing disk 31 of the present invention is provided with a plurality of fin holes 32, and the adjusting member 4 is provided with fins 42 slidably connected to the plurality of fin holes 32. The adjusting member 4 slides to adjust the position of the fins 42 extending into the filling space 21. The filling space 21 is provided with resistance sheets 22 corresponding to the fins 42. The fins 42 and the resistance sheets 22 cooperate to shear the non-Newtonian fluid 6, and a certain gap is provided between the resistance sheets 22 and the fins 42 to ensure that when the adjusting member 4 rotates inside the filling space 21, the resistance sheets 22 and the fins 42 rotate relative to each other, thereby generating a shear force between the non-Newtonian fluid 6 and achieving a braking effect on the adjusting member 4. A reset spring 5 is provided between the adjusting member 4 and the sealing disk 31. When the rotation speed of the adjusting member 4 is within a predetermined value, the adjusting member 4 can retract to its original position to prevent the non-Newtonian fluid 6 from hindering the rotation of the adjusting member 4 and increasing the energy consumption of the elevator.

[0027] See also Figure 1 to Figure 8 In addition, a slide groove 34 is provided between the guide wheel 3 and the rotating shaft of the present invention, and a trigger sleeve 10 is slidably connected inside the slide groove 34. A trigger spring 9 is provided between the trigger sleeve 10 and the bottom of the slide groove 34. The trigger spring 9 cooperates with the trigger sleeve 10 to ensure that when the rotation speed of the guide wheel 3 is fast, the trigger spring 9 at this time pushes the trigger sleeve 10 to insert the adjusting member 4 into the filling space 21, thereby realizing rapid emergency braking of the guide wheel 3, protecting the car, and preventing the car from falling rapidly. A trigger component for controlling the triggering of the trigger sleeve 10 is provided on the wheel body 33 of the guide wheel 3, and the trigger component includes a trigger assembly opened on the guide wheel 3. The sliding holes 35 on the two side walls of the guide wheel 3 and the clamping columns 7 slidably connected to the inside of the sliding holes 35, a clamping spring 8 is provided between the clamping column 7 and the bottom of the sliding hole 35, and the clamping spring 8 pushes the clamping column 7 to clamp the trigger sleeve 10 into the inside of the slide groove 34. When triggered, the guide wheel 3 at this time rotates faster, resulting in an increase in the centrifugal force on the clamping column 7, thereby compressing the clamping spring 8, and the clamping column 7 retracts into the sliding hole 35. At this time, the trigger sleeve 10 is no longer restricted, so that the adjusting member 4 is instantly pressed into the filling space 21, thereby realizing emergency braking of the guide wheel 3, thereby protecting the car and the people inside.

[0028] Furthermore, a limiting portion is provided at the top of the sliding hole 35 of the present invention, and a limiting flange 72 is provided at the top of the clamping column 7 to cooperate with the limiting portion. The limiting portion and the limiting flange 72 cooperate to limit the extended position of the clamping column 7 to prevent the clamping column 7 from sliding out of the sliding hole 35 and affecting the use of the clamping column 7. At the same time, a clamping convex edge 71 is provided at the bottom of the clamping column 7, and a guiding bevel is provided on the side of the clamping convex edge 71 away from the trigger sleeve 10 to ensure that when the trigger sleeve 10 retracts, the trigger sleeve 10 can push the clamping column 7 up The trigger sleeve 10 is lifted up and retracted into the sliding hole 35, thereby resetting the trigger sleeve 10 to its initial position. When the rotation speed of the guide wheel 3 reaches a certain value, the clamping column 7 is compressed by the centrifugal force to compress the clamping spring 8, so that the clamping column 7 is retracted into the sliding hole 35. The clamping convex edge 71 is separated from the trigger sleeve 10, and the trigger sleeve 10 is pushed by the trigger spring 9 to compress the adjusting member 4 into the filling space 21, thereby increasing the resistance between the adjusting member 4 and the filling space 21, thereby achieving a rapid braking effect on the car.

[0029] Preferably, the adjusting member 4 of the present invention is provided with a push-up flange 41 on one side adjacent to the trigger sleeve 10, and the push-up flange 41 abuts against the end of the trigger sleeve 10. At the same time, the push-up flange 41 is between the clamping flange 71 and the inner wall of the slide groove 34, ensuring that the push-up flange 41 can directly abut against the trigger sleeve 10. The push-up flange 41 compresses the trigger sleeve 10 to the inner edge of the clamping flange 71 when resetting. The adjusting member 4 is made of magnetic material, and a coil fixed to the shell 2 of the filling space 21 is wound around the outside of the adjusting member 4. The coil is powered to generate a magnetic field to drive the The adjusting member 4 slides inside the filling space 21, so that when the rotation speed of the guide wheel 3 is not too fast, the speed of the guide wheel 3 can be directly detected, and then the coil can be controlled to be powered on and off, so as to control the adjusting member 4 to be inserted into the filling space 21. At this time, it is applicable that the car may be in a fault state, and the moving speed is within the limit speed but greater than the normal speed. At this time, the power supply intensity of the coil can be controlled to control the position of the adjusting member 4 inserted into the filling space 21, and the braking force of the guide wheel 3 can be further controlled to adjust the movement of the car to a suitable position.

[0030] In this embodiment, combined with Figure 1 to Figure 8When in use, the car is connected to the guide wheel 3 through the drag rope. When the elevator is in normal use, the guide wheel 3 is driven to rotate by the driving motor, thereby driving the normal lifting and lowering of the car. When the moving speed of the car is abnormal (that is, the moving speed of the car becomes faster but is less than the predetermined limit speed), the control system can be used to control the coil to be energized and control the movement of the magnetic adjustment member 4 to increase the rotation resistance of the rotating shaft, thereby adjusting the speed of the car. When the car speed increases rapidly and reaches the limit value (the car is in a falling state at this time), under the action of the centrifugal force of the rotation, the clamping column 7 is forced to retract into the inside of the sliding hole 35, and then the contact at this time Under the action of the trigger spring 9, the trigger sleeve 10 quickly pushes the adjusting member 4 to move toward the inside of the filling space 21, and the fin 42 is directly inserted into the inside. At this time, the braking force increases, and the speed of the car is quickly reduced to protect the car and prevent the car from falling. After the car is in a normal state, the coil is reversely energized through the control component. At this time, the clamping column 7 has been reset under the action of the clamping spring 8, and then the reset spring 5 and the reverse magnetic field force of the coil work together to push the adjusting member 4 in the reverse direction and push the trigger sleeve 10 back to the initial position. The clamping column 7 clamps the trigger sleeve 10 again to complete the reset process of the protective device to ensure that it can be reused.

The rotating shaft of the guide wheel 3 is rotatably connected to the inside of the filling space 21, and a sealing disk 31 for sealing the filling space 21 is fixed to the outside of the rotating shaft. An adjusting member 4 is slidably connected to the sealing disk 31, and the adjusting member 4 slides on the sealing disk 31 to control the position of the adjusting member 4 into the filling space 21. The adjusting member 4 adjusts the resistance between the rotating shaft and the non-Newtonian fluid 6, thereby adjusting the resistance encountered by the adjusting member 4 by the depth of the position inserted into the non-Newtonian fluid 6, thereby controlling the resistance encountered by the guide wheel 3, and controlling and adjusting the moving speed of the car. In summary, the technical effect produced by the present invention is to set up a structure that can be automatically controlled to ensure that when the speed of the elevator needs to be controlled, the rotation speed of the elevator is controlled by controlling the position of the adjusting member 4, and at the same time ensure that the elevator directly bounces up and slows down when it moves rapidly to prevent the car from falling.
