The scheme is as follows: a torque motor 31 is fixedly installed on the left side inside the control room 5, a driving gear 32 is fixedly connected to the torque motor 31, a coaxial driven gear 33 is fixedly connected to the outer side of the traction wheel 8, and the driven gear 33 is meshed and connected with the driving gear 32, and the driving gear 32 is smaller than the driven gear 33, an energy storage unit 34 is installed on the left side of the control room 5, and an energy storage controller 35 is electrically connected to the energy storage unit 34, and the energy storage controller 35 is connected to the torque motor 31 through wires; a brake frame 36 is fixedly provided at the front end of the control room 5, a brake electric push rod 37 is bolted to the middle part of the front end of the brake frame 36, and the rear end of the brake electric push rod 37 passes through the brake frame 36 and is connected to a brake plate 38, and the brake plate 38 can abut against the first steel wire rope 10 under the pushing action of the brake electric push rod 37, thereby having a braking effect on the first steel wire rope 10. In the process of driving the car body 6 to rise and fall by relying on the weight difference between the counterweight frame 14, the counterweight block 15 and the car body 6, the first steel wire rope 10 needs to be driven to move synchronously. The first steel wire rope 10 will drive the traction wheel 8 to rotate, and then drive the torque motor 31 to rotate and generate electricity through the driven gear 33 and the driving gear 32. Then, through the cooperation between the energy storage unit 34, the energy storage controller 35 and the torque motor 31, the kinetic energy generated during the lifting and lowering of the car body 6 is converted into electrical energy, and the recovered electrical energy is collected through the energy storage unit 34. At the same time, a certain resistance will be generated during the kinetic energy recovery process, which can limit the speed of the car body 6 falling. In order to ensure the stability of the car body 6 during lifting and lowering, a brake assembly is provided. The brake electric push rod 37 pushes the brake plate 38 to move backward so as to abut and rub against the first steel wire rope 10, thereby providing a braking effect, which can save a certain amount of electrical energy during long-term elevator teaching simulation.
