Description

Double-machine traction device
Technical Field
The invention relates to a traction device, in particular to a double-machine traction device with a main traction motor and a rescue motor.
Background
In high-rise buildings, in order to meet the requirement of height change, the lifting device is necessary supporting equipment, such as an elevator, and great convenience can be brought to users.
The elevator is a vertical elevator powered by an electric motor, also known as a vertical elevator. Vertical elevators are equipped with box-like pods for use in multi-story buildings for boarding or carrying cargo. From the earliest first-step safety elevators to modern automatic control elevators, although developed for several hundred years, most of the elevators are driven by traction drive mechanisms comprising a traction machine arranged at the top of the hoistway, the traction machine being connected to a traction sheave, the traction sheave being wound with a hoisting rope, one end of which is connected to the car and the other end of which is connected to a counterweight for balancing the weight of the car. When the traction machine drives the traction sheave to rotate, traction force generated by friction between a traction rope wound on the traction sheave and the traction sheave realizes lifting movement of the car and the counterweight.
In the using process of the elevator, the most serious accident is that the elevator car is quickly pushed or squatted, a light person causes the damage of the body of the passenger and the elevator, and serious passengers can even die. For this purpose, various devices and methods have been devised for improving the safety of elevator operation, the main way of which is to provide an electromagnetically controlled braking mechanism on the hoisting machine. When the elevator fails or the elevator fails, the control system cannot supply power to the elevator, the electromagnet in the braking mechanism is powered off and loses magnetic attraction power, and at the moment, the braking mechanism continues to act by means of the acting force of the braking spring, so that the traction machine can be locked and braked; when the elevator is electrified, the electromagnet in the braking mechanism is electrified, so that the braking mechanism contacts to lock the traction machine, and the elevator can normally run.
For example, an elevator traction machine disclosed in chinese patent literature has a publication number CN2401528Y, and includes a base, a motor, a worm gear case, a worm wheel shaft, a hanging leg, a worm wheel, a traction wheel, and a brake mechanism, wherein one end of the worm wheel shaft is provided with an eccentric sleeve, a connecting disc is provided in the middle of the worm wheel shaft, one end of the connecting disc is fixed with the worm wheel, the other end is fixed with the traction wheel, bearings are provided between the connecting disc and the worm wheel, and between the connecting disc and the traction wheel, respectively, and an adjusting pad is provided at the bottoms of a pair of hanging legs provided with the worm wheel shaft. When the elevator car is in operation, the power supply is firstly switched on, the brake mechanism is in an electrified state through the control switch, meanwhile, the motor drives the worm wheel to operate through the worm, and then the traction wheel is driven to rotate through the connecting disc, and the elevator car can be driven to lift by a rope wound on the traction wheel. When the car moves to a predetermined destination floor, the motor is stopped by operating the control switch and braked by the brake mechanism. The braking principle is as follows: when the motor is powered off, the electromagnetic valve of the braking mechanism is powered off, the braking wheels are locked by the pair of band-type brakes under the action of spring force, and the motor shaft is rapidly stopped by the friction force between the cap tile on the band-type brake and the braking wheels, so that the elevator car can be stably stopped.
However, in the braking mechanism with the structure, the band-type brake is required to apply the holding force, if the holding force of the band-type brake is insufficient, the car cannot be braked rapidly, and the lifting movement exists, so that passengers in the car are easy to panic. And after the band-type brake is tightly held and braked, self rescue cannot be realized on site, special rescue personnel are required to carry out external rescue through a series of complex mechanisms, the waiting time for rescue is relatively long, the rescue process is dangerous, passengers in the lift car cannot be rescued for the first time, and the rescue opportunity can be delayed.
Disclosure of Invention
The invention solves the defects that the existing elevator can not brake rapidly due to insufficient holding force of the band-type brake, the braking reliability is low and the safety of the elevator is low, and provides the double-machine traction device which can brake rapidly when an elevator system fails and can brake directly in a traction wheel locking mode, so that the braking reliability is high and the safety accidents of the car in a top-rushing or squatting manner can be effectively avoided.
The invention also solves the defects that the existing elevator cannot save oneself, an external professional rescue team is needed to rescue, the waiting time in the elevator car is long, and the first rescue time is easy to lose.
The specific technical scheme of the invention is as follows: a double machine traction device comprising:
a traction machine as a power source for lifting the car;
The traction sheave is connected with the traction machine and driven by the traction machine, and a traction rope is wound on the traction sheave and is connected with the lift car to pull the lift car to lift;
The worm gear and worm mechanism is coaxially connected with the traction sheave and synchronously rotates along with the traction sheave, and the worm gear are meshed to form a locking mechanism of the traction sheave;
the rescue motor is connected with the worm, and only drives the worm to rotate when rescue is needed, so as to drive the worm wheel to rotate and drive the traction sheave to rotate to rescue the car;
and the synchronous mechanism adopts a mechanical transmission mode, is connected with the worm and drives the worm to rotate synchronously with the worm wheel, and the worm is always separated from the worm wheel when the elevator normally operates.
The application is provided with a worm gear mechanism, and the worm gear is coaxially connected with the traction sheave. It is known that worm gears have a self-locking effect, that is, the worm cannot drive the worm to rotate, and only the worm can drive the worm to rotate. Therefore, the application is provided with a purely mechanical synchronous mechanism to realize the synchronization of the worm and the worm wheel, the worm and the worm wheel keep synchronous, the worm cannot cause self-locking on the worm wheel, namely, the worm wheel is driven by a traction machine like a traction wheel at the moment, the worm is driven by a synchronous motor, and the worm wheel and the worm are in mutually independent states, so that the worm cannot form an obstacle to the rotation of the worm wheel. The power source of the synchronous mechanism can come from a traction machine, a traction wheel and a worm wheel, and of course, the power source from the worm wheel is transmitted to the worm, a clutch is required to be arranged, the transmission of the clutch can be disconnected when the worm is required to be self-locked, and the proper transmission ratio of the synchronous mechanism is required to be designed according to different power sources, so that the synchronization of the worm and the worm wheel is ensured. When the system is in power failure, the worm stops rotating, so that reliable mechanical self-locking can be formed on the worm wheel, and further, reliable braking is formed on the traction wheel; when the speed of the traction machine is abnormal due to out-of-control, the worm wheel and the worm cannot form synchronization, and the worm can automatically block the rotation of the worm wheel at the moment, so that the rapid top-punching or squatting of the lift car can be avoided. In the prior art, a worm gear is a transmission mechanism with a self-locking effect, and in order to improve safety, people can arrange sensors capable of detecting the lifting speed of a car on an elevator so as to cut off a power supply and brake a traction machine when the car is lifted quickly. The worm gear has a self-locking function, and can form a reliable mechanical sensing device, so that on one hand, the traction wheel is reliably braked when power failure or abnormal conditions occur to the traction machine, and on the other hand, abnormal operation of the traction machine can be timely perceived, and further, the safety of the elevator during operation can be remarkably improved. The worm wheel synchronously rotates along with the traction sheave, the worm is connected with the rescue motor, the load of the worm is far smaller than that of the traction sheave, the worm is equivalent to no load and only drives the motor shaft of the rescue motor to rotate, so that the safety of the synchronous mechanism is reliable, and compared with the safety coefficient of the traction mechanism formed by the traction machine and the traction sheave, the synchronous mechanism basically does not react to the traction mechanism.
