Description

Technical Field

[0001] The invention relates to the technical field of elevator counterweights, and in particular to an elevator counterweight energy-saving control system with low energy consumption. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type elevators, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. They are fixed lifting equipment that serves specified floors. Vertical elevators have a car that runs between at least two rows of vertical or rigid guide rails with an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation vehicles in buildings regardless of their driving mode. Traditional elevator counterweights are fixed weights, which result in uneven force on the manned and unmanned steel cables of the elevator, reducing their lifespan and poor balance. This results in greater energy consumption of the elevator and reduces its performance. Therefore, a low-energy-consuming elevator counterweight energy-saving control system is proposed.

[0035] Example 3

[0036] like Figure 1-6As shown, on the basis of Embodiment 1-2, the present invention provides a technical solution: preferably, a mounting frame 316 is fixedly installed on the upper surface of the I-beam frame 312, and a rope pulley 317 is rotatably connected to the upper surface of the mounting frame 316. The outer surface of the rope pulley 317 is rotatably connected to the outer surface of the brake wheel 315 through a steel cable 319. An auxiliary wheel shaft 318 is provided on the side of the brake wheel 315 away from the rope pulley 317. The outer surface of the auxiliary wheel shaft 318 is movably connected to the outer surface of the steel cable 319. Air inlets and air outlets are respectively provided on the outer surfaces of both sides of the drive control box 311, and a movable groove is provided on the lower surface of the mounting top plate 411. A driving motor 2 412 is fixedly installed on one end of the mounting top plate 411. A threaded rod 413 is fixedly connected to the output shaft of the driving motor 2 412.

[0037] The following is a detailed description of the working principle of this low-energy elevator counterweight energy-saving control system.

[0038] like Figure 1-6As shown, when using the elevator, first, the driving device 3 is turned on, and the brake wheel 315 is rotated by starting the driving motor 314. Under the action of the active rotation force, the steel cable 319 moves on the surface of the rope wheel 317, and drives the rope wheel 317 to rotate. In addition, the auxiliary wheel shaft 318 is used to reduce the friction force when the steel cable 319 moves, reduce wear, and improve the overall balance, so that the overall drive is more labor-saving and energy consumption is reduced. With the setting of the weighing sensor 32, the data signal is fed back to the controller for signal transmission. Then, through the traction of the steel cable 319, the counterweight block 213 drives the circular sliding sleeve 212 to slide on the surface of the track slide bar 211. Through such a setting, it can play a supporting role while ensuring the effect of reducing friction during the lifting process. The mutual cooperation of the auxiliary buffer roller 233 and the elevator chassis track 234 improves the smoothness of the elevator chassis 232 when lifting and lowering, and reduces the friction force during movement, making it more labor-saving and reducing energy consumption. Yes, through the cooperation of the articulated balance bar 24 and the lifting block 241, the balance of the steel cable 319 during traction is improved, and the overall stability is improved. Then, through the cooperation of the curved elastic buffer plate 235 and the buffer spring 236, the two will generate reverse elastic forces when subjected to external pressure, thereby achieving the effect of shock absorption and buffering, and protecting the elevator. It utilizes the interaction between the sleeve 221 and the top impact lifting sleeve rod 222 to provide a buffer space for the counterweight block 213, thereby avoiding direct falling and affecting the performance of the elevator. In addition, by turning on the drive motor 2 412, the threaded rod 413 is rotated. Under the action of the rotational force, the brake slider 414 drives the fan 415 to translate as a whole, ensuring the heat dissipation of the interior of the drive control box 311 as a whole, preventing the heat generated by the drive device 3 during long-term operation from causing local overheating, enhancing the overall effectiveness and stability, and further extending the service life of the elevator as a whole. At the same time, it also reduces the maintenance cost and avoids the situation of long-term operation in a high-temperature state.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
