Abstract
The invention discloses an electric shovel hoisting system. The electric shovel hoisting system comprises a control system, a shovel bucket, a steel wire rope, a head sheave, a winding drum assembly, an edge part support, a winding drum, a speed reducer, a motor end support, a motor and a brake. The speed reducer is a compact type low-inertia speed reducer. An intelligent power generation control module is mounted in the control system. When the shovel bucket falls back, the control system enables the hoisting system to be switched from an original power supply mode to a power generation mode, and the shovel bucket drives the winding drum to rotate reversely; at the moment, the winding drum becomes a driving part and drives the motor to rotate through the speed reducer in the winding drum, the motor becomes a power generator and converts gravitational potential energy of the shovel bucket and a bucket rod into electric energy, and the electric energy is fed back to a power grid or supplied to an electric shovel and other electric equipment for use after being transmitted to a control cabinet through a power supply circuit and being subjected to rectification and inversion. Since the compact type low-inertia speed reducer is adopted for the electric shovel hoisting system and mounted in the winding drum, the power generation efficiency is improved.
Description
Technical field
The present invention relates to a kind of mining equiment, particularly a kind of Hoisting System of power shovel.
Background technology
Energy-saving and emission-reduction, green manufacturing are the Developing mainstreams of current equipment manufacture, as the power shovel of the important extractive equipment of energy field, ought to contribute in energy-conservation, green manufacturing.The agent structure of the main flow Hoisting System of current power shovel is that employing two motor dual inputs drive an external cylindrical gear reducer, through deceleration rear drive spool turns, the installed power of Hoisting System almost accounts for the half of whole power shovel installed power, the half that the weight of whole scraper bowl and dipper accounts for power shovel hoisting power also wants many, but in each mining process, have most of power to be doing without benefit work; If the gravitional force of scraper bowl and dipper effectively can be utilized in scraper bowl falling process, by conversion, part gravitional force is become electric energy, this significantly works, not only save cost to user, increase the competitiveness of product, and meet the requirements of the times of current energy-saving and emission-reduction, environmental protection completely.
Summary of the invention
For solving the problems referred to above that prior art exists, the present invention will design a kind of Hoisting System of energy-conservation power shovel.
To achieve these goals, technical scheme of the present invention is as follows: a kind of Hoisting System of power shovel, comprise control system, scraper bowl, wire rope, head sheave, reel assembly, edge support, reel, reductor, motor side supporting, motor and brake, described reductor is compact low inertia reductor.
Described control system is arranged in the switch board of power shovel, is connected with motor by data wire, is provided with intelligent power generation control module in described control system.
Described reel assembly is fixed on the slewing frame of power shovel by support, and wire rope is coupled together scraper bowl and reel assembly by head sheave.Scraper bowl is arranged on swing arm by dipper.
Described edge support one end be arranged on be equipped with on the support of bearing, other end bolton on reel, reductor is arranged on reel inside, is fixed by bolt and seam.Described motor side supporting bolt and seam support reductor, and motor is also installed in motor side supporting simultaneously, and motor is connected with the power shaft of reductor by shaft coupling, and described brake is arranged on motor.
Operating principle of the present invention is as follows:
When scraper bowl falls after rise, control system is switched to power generation mode original Hoisting System powering mode, scraper bowl band movable reel reverses, at this moment reel just becomes driving link, and reel is rotated by the reductor CD-ROM drive motor of its inside, and motor just becomes a generator, the gravitional force of scraper bowl and dipper is changed into electric energy, by supply line, electric energy is passed to switch board, after commutation inversion, feed back to electrical network or use to other consumer of power shovel altogether.
Compared with prior art, the present invention has following beneficial effect:
1, owing to present invention employs the reductor of compact low inertia, and reductor is installed on reel inside, thus improves generating efficiency.
2, the present invention adds the module of a set of Generation Control in original switch board, carries out intelligent management to power generation process.
3, the present invention utilizes the gravitional force of scraper bowl and dipper to do work, and after wire rope and hoisting drum assembly, CD-ROM drive motor generates electricity, and the electric energy sent is by after switch board commutation inversion, and on supply power shovel, other electric fixtures uses, and saves electric energy.
4, the present invention is compared with traditional equipment, eliminates a motor, a two-stage straight-tooth gear reductor and two motor bases, the volume of whole system and weight is reduced greatly, reduces the dynamic moment of inertia of rotating part, make turning motor more power saving.
