The ratchet wheel 22 is sleeved outside the rotating wheel 21, the inner peripheral surface thereof is provided with a rotating part 221 which is in rotating fit with the rotating wheel 21 and a first transmission part 222 which is provided with ratchet teeth in the whole circumferential direction, the outer peripheral surface thereof is provided with a second transmission part 223, and the second transmission part 223 is a gear structure which is used for being meshed with the rack 23. The rack 23 is longitudinally disposed on an inner wall of the hoistway, and preferably, the rack 23 includes a plurality of rack bodies 231, and the rack bodies 231 are made of metal or alloy, that is, the rack 23 mainly includes a plurality of rack bodies 231, so that the manufacturing and installation are convenient. One end of the pawl 24 with the runner 21 is articulated, the other end with first transmission portion 222 conflicts, specifically, the pawl one end pass through the hinge 211 with the runner 21 is articulated, the cover is equipped with the torsional spring (not shown in the drawing) on the hinge 211, makes through the torsional spring the pawl 24 the other end keep with first transmission portion 222 conflicts, the cover of flywheel 4 is established on the input shaft of generator 1, energy memory 3 with generator 1 electricity is connected, energy memory 3 can be battery, electric capacity etc.
As shown in fig. 1, during the descending process of the elevator, the second transmission part 223 is engaged with the rack 23, the ratchet wheel 22 rolls down along the rack 23, the ratchet wheel 22 rotates clockwise, the first transmission part 222 of the ratchet wheel 22 drives the rotating wheel 21 to rotate through the pawl 24, the rotating wheel 21 drives the input shaft of the generator 1 and the flywheel 4 to rotate simultaneously, the generator 1 generates electricity, and the generated electricity is input to the energy storage device 3 to be stored. When the elevator stops, under the action of inertia, the flywheel 4 continues to rotate, so that the generator 1 is driven to continue generating power, and finally the potential energy recovery efficiency is improved. During the ascending process of the elevator, the second transmission part 223 is meshed with the rack 23, the ratchet wheel 22 rolls upwards along the rack 23, the ratchet wheel rotates along the anticlockwise direction, the pawl 24 slides on the first transmission part 222, the rotating wheel 22 does not rotate, the generator 1 does not work, and the burden of the driving motor is not increased.
As an improvement of the above scheme, as shown in fig. 1, the elevator car further includes a support rod 5 and a first spring 6, a horizontal guide hole 7 is formed in an inner wall of the hoistway, one end of the support rod 5 is slidably disposed in the horizontal guide hole 7, and the other end of the support rod is fixedly connected to the rack body 231, preferably, at least two support rods 5 are disposed at upper and lower ends of the rack body 231, respectively, so as to better support the rack 23, and the one end of the support rod 5 is provided with an anti-drop structure 51.

When the elevator shakes during operation and moves transversely, the ratchet wheel 22 presses the rack 23, the rack 23 pushes the support rod 5 to move in the transverse guide hole 7 in a direction away from the ratchet wheel 22 and compress the first spring 6, and when the elevator returns to normal operation, the rack 23 returns to a normal position under the elastic force of the first spring 6. Therefore, the ratchet wheel 22 and the rack 23 can be kept meshed at any time, and the damage caused by the rigid meshing of the ratchet wheel 22 and the rack 23 when the elevator shakes in the running process of the elevator is avoided.
As an improvement of the above scheme, as shown in fig. 3, the one end of the support rod 5 is provided with mounting holes 52, preferably, the number of the mounting holes 52 is 2 to 4, and the mounting holes 52 are uniformly arranged along the circumferential direction, one end of the mounting hole 52 is close to the one end of the support rod 5, the other end of the mounting hole 52 is far away from the one end of the support rod 5, and an axis of the mounting hole 52 and an axis of the support rod 5 form an included angle, preferably, the included angle is within a range. The falling off preventive structure 52 includes a ball 511 and a second spring 512 both disposed in the mounting hole 52.
Naturally, the second spring 512 holds the ball 511 at the one end of the mounting hole 52, and a part of the surface of the ball 511 is located outside the circumferential surface of the support rod 5; when the ball 511 is subjected to an external force, the ball 511 can move toward the other end of the mounting hole 52, the ball 511 can move at least to a position where the surface thereof is completely located within the circumferential surface of the support rod 5, and the ball 511 compresses the second spring 512 during the movement.
As shown in fig. 3, in the process of inserting the support rod 5 into the lateral guide hole 7 rightward, the balls move from the right end to the left end of the mounting hole 52 to at least a position where the balls are completely located below the circumferential surface of the support rod 5, and in this process, the second spring 512 is compressed to accumulate elastic potential energy. When the support rod 5 passes through the lateral guide hole 7, the ball 511 returns to the right end of the mounting hole 52 by the second spring 512, and at this time, the first spring 6 has a tendency to move the entire support rod 5 to the left, but since the ball 511 is held at the right end of the mounting hole 52 by the second spring 512, in this position, a part of the surface of the ball 511 is located outside the circumferential surface of the support rod 5, thereby preventing the support rod 5 from moving to the left.
As can be seen from the above description, the anti-falling structure 51 can prevent the support rod 5 from falling off from the transverse guiding hole 7, and the simple structure of the anti-falling structure 51 does not affect the installation of the support rod 5 itself.
