Intelligent vertical tractor

Abstract

The invention discloses an intelligent vertical traction machine, which comprises a guide rail and a traction support frame, wherein the guide rail is arranged in an elevator liftway, the traction support frame is arranged on the guide rail through a pulley, the traction support frame drags an elevator lift car, a worm rod rack is arranged on the guide rail, a main motor and a turbine rack are arranged in the traction support frame, the turbine rack realizes the matched transmission with the worm rod rack, an auxiliary motor is also arranged on the traction support frame, and is connected with a harmonic speed change gear, and a vertical straight rack mutually matched with the harmonic speed change gear is arranged on the guide rail. The traditional friction traction is changed into the turbine rack and worm rod rack matched traction, so the self locking function is realized during object carrying, and the operation safety of an elevator is ensured; meanwhile, the harmonic speed change gear is used for auxiliary driving, the multi-machine traction is adopted, the transmission efficiency is high, the energy is allocated according to requirements, and the goal of energy saving is achieved; the load capacity increase is realized through increasing the number of the traction support frame according to load requirements, the structure is simpler, the installation is convenient, and the occupation of a greater space is not needed.

Description

technical field [0001] The invention relates to an intelligent vertical tractor, in particular to an intelligent vertical tractor used for traction of an elevator car. Background technique [0002] As a vertical means of transportation, the elevator has been closely related to people's life. Its working principle is: the two ends of the traction rope are respectively connected to the car and the counterweight device, the traction rope is wound on the traction wheel and the guide wheel, and the traction motor drives the traction When the wheel rotates, the traction is generated by the friction between the traction rope and the traction wheel to realize the lifting movement of the car and the counterweight to achieve the purpose of transportation. [0003] The above structure has the following problems: [0004] 1. When the system is moving or stationary, the safe operation is guaranteed by the brake device, safety gear and other devices. If these devices break down, there w...

Problems solved by technology

If these devices fail, there will be situations that endanger the lives of passengers, such as car slipping, rushing to the top, squatting, and speeding.

[0005] 2. The structure is complex. Both the car and the counterweight device need guide rails and a large number of steel wire ropes. These equipment need a large amount of steel, and the production of steel needs to consume a lot of energy, which is neither energy-saving nor environmentally friendly.

[0006] 3. The installation and commissioning are complicated, and it is very difficult to level the floor, adjust the safety gear, and adjust the comfort. It requires certain professional knowledge and level for the installation and commissioning personnel

[0007] 4. The energy-saving effect is poor when the system is running. During the operation of the elevator, the actual load of the elevator changes randomly from zero to the rated load, and the output energy of the elevator traction machine cannot be adjusted according to the displacement direction of the car and the actual load. dynamic allocation

[0008] 5. Due to the counterweight device, the space requirement for the hoistway is large

[0010] 7. The elevator traction machine works in two states of motor and generator, so the corresponding control system is quite complicated
