Abstract
The invention discloses an electric arc steelmaking furnace with a furnace door operating device. The electric arc steelmaking furnace comprises a furnace body and a furnace door, wherein the furnace door is arranged in the center of the furnace body, a transmission shaft is transversely arranged at the upper end of the furnace door, bearing blocks are symmetrically connected to two ends of the transmission shaft, pulleys are symmetrically arranged outside the two bearing blocks, a bevel gear is arranged outside the pulley on one side of the transmission shaft and connected with a motor through a worm gear and a worm, the other end of the motor is connected with a cable, a steel rope is arranged at the lower end of each pulley, the lower end of each steel rope is connected with a counterweight, and a positioning bush is arranged at the lower end of each counterweight. The electric arc steelmaking furnace with the furnace door operating device has the advantages of simple structure, skillful design and convenience in installation and is stable in transmission and easy to maintain. Furnace opening time is shortened, and a large quantity of resource and energy are saved.
Description
Technical field:
The present invention relates to a kind of electric furnace arrangement for producing steel that has door open and close device.
Background technology:
At present, the fire door of electric furnace arrangement for producing steel generally adopts the air pump transmission, needs supporting air compressor machine do propulsion source, has not only taken very large space, also causes the waste of the energy and fund, and operation and ME more complicated all.
Summary of the invention:
The objective of the invention is provides a kind of structure ingenious in order to overcome above deficiency, has the electric furnace arrangement for producing steel of door open and close device.
The object of the invention is realized a kind of electric furnace arrangement for producing steel that has door open and close device through following technical scheme, comprises body of heater and fire door, is provided with fire door at the body of heater center; Laterally be provided with transmission shaft in the fire door upper end, be symmetrically connected with chock, be arranged with pulley in two chock outsides at the transmission shaft two ends; The outside of the pulley of a side is provided with conical gear therein; Conical gear is connected with phonomoter with worm screw through turbine, and the other end of phonomoter is connected with cable, is provided with steel cable in each pulley lower end; All be connected with counterweight in each steel cable lower end, be provided with locating sleeve in each counterweight lower end.
The present invention compared with prior art has following characteristics:
The present invention signs an undertaking, and structure is simple, exquisite, the convenient installation of design, stable drive, and ME is simple, has reduced the blow-on time, has practiced thrift the ample resources and the energy.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Label among the figure: 1-fire door 2-counterweight, 3-steel cable, 4-pulley, 5-chock, 6-transmission shaft, 7-turbine, 8-worm screw, 9-phonomoter, 10-cable, 11-conical gear, 12-locating sleeve, 13-body of heater.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show the present invention like Fig. 1; A kind of electric furnace arrangement for producing steel that has door open and close device comprises body of heater 13 and fire door 1, is provided with fire door 1 at body of heater 13 centers; Laterally be provided with transmission shaft 6 in fire door 1 upper end, be symmetrically connected with chock 5, be arranged with pulley 4 in two chock 5 outsides at transmission shaft 6 two ends; The outside of the pulley 4 of a side is provided with conical gear 11 therein; Conical gear 11 is connected with phonomoter 9 with worm screw 8 through turbine 7, and the other end of phonomoter 9 is connected with cable 10, is provided with steel cable 3 in each pulley 4 lower end; All be connected with counterweight 2 in each steel cable 3 lower end, be provided with locating sleeve 12 in each counterweight 2 lower end.
Directly drive conical gear 11 by phonomoter 9, diameter worm 8, turbine 7 reach the transmission shaft 6 on the fire door 1, and fire door 1 opens and closes the balance that is kept fire door 1 by counterweight 2, realize positioning action through locating sleeve 12, and be easy to operate, stable drive, and ME is simple.
