Abstract
The invention discloses a furnace door hoisting device. The furnace door hoisting device comprises a furnace door which is installed on the front side of a furnace body. A hoisting device for hoisting the furnace door is arranged above the furnace door, driven by a motor and comprises a supporting frame, two slings and four fixed pulleys, the supporting frame is located outside the furnace door, the two slings are symmetrically arranged, one end of each sling is fixedly connected with the upper portion of the furnace door, and the other end of each sling is connected with a balance block which moves up and down along sliding chutes in the lateral sides of the supporting frame. According to the furnace door hoisting device, the balance block is additionally arranged at the tail ends of the slings, part of weight of the furnace door can be offset, working pressure of the motor is relieved, and therefore energy is saved.
Description
Technical field
The present invention relates to a kind of fire door hoisting device of industrial furnace.
Background technology
The fire door of industrial furnace generally all moves up and down switch, because fire door is heavier, generally has 30-40 ton, so in the process of upper and lower switch, need the power ratio of motor larger, adopts and reaches the requirement that drives fire door motion, relatively expends the energy.
Summary of the invention
The technical issues that need to address of the present invention are that existing fire door hoisting device relatively expends the energy.
For solving the problems of the technologies described above, the invention provides a kind of fire door hoisting device, comprise fire door, described fire door is arranged on body of heater front side, above described fire door, be provided with the boom hoisting that fire door is sling, described boom hoisting comprises the bracing frame that is positioned at described fire door outside, article two, hoist cable and four fixed pulleys, described two hoist cables are symmetrical arranged, one end is fixedly connected with described fire door top, the other end is connected with the balance weight moving up and down along the chute of support frame as described above side, one end that described two hoist cables are connected with described balance weight is respectively by driven by motor, every described hoist cable mid portion is by the fixed pulley of two described hoist cable directions of change, one of them fixed pulley is arranged on support frame as described above centre position, and be positioned at described hoist cable and fire door fixing point directly over, another fixed pulley is arranged on the corner of support frame as described above.Fire door hoisting device of the present invention, increases balance weight by the end at hoist cable, can offset the weight of a part of fire door, alleviates the operating pressure of motor, thereby saves the energy.
As the preferred technical solution of the present invention, the end of described balance weight and described hoist cable removably connects.Can realize by removably connecting and increase balance weight or do not add balance weight or change the multiple choices such as size of balance weight, can adapt to flexibly various situations.
Fire door hoisting device of the present invention, by the each operating pressure that increases a balance weight and alleviate motor of the end at two hoist cables, simple and practical, save the energy.

Fig. 2 is right view of the present invention;
Wherein, 1-fire door, 2-body of heater, 3-bracing frame, 4-hoist cable, 5-fixed pulley, 6-balance weight, 7-chute, 8-motor.
The specific embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in the figure, fire door hoisting device of the present invention, comprise fire door 1, described fire door 1 is arranged on body of heater 2 front sides, above described fire door 1, be provided with the boom hoisting that fire door 1 is sling, described boom hoisting comprises the bracing frame 3 that is positioned at described fire door 1 outside, article two, hoist cable 4 and four fixed pulleys 5, described two hoist cables 4 are symmetrical arranged, one end is fixedly connected with described fire door 1 top, the other end is connected with the balance weight 6 moving up and down along the chute 7 of support frame as described above 3 sides, and described balance weight 6 removably connects with the end of described hoist cable 4, described two hoist cables 4 are driven by motor 8 respectively with one end that described balance weight 6 is connected, every described hoist cable 4 mid portions are by the fixed pulley 5 of two described hoist cable 4 directions of change, one of them fixed pulley 5 is arranged on support frame as described above 3 centre positions, and be positioned at directly over described hoist cable 4 and fire door 1 fixing point, another fixed pulley 5 is arranged on the corner of support frame as described above 3.
Fire door hoisting device of the present invention, increases balance weight by the end at hoist cable, can offset the weight of a part of fire door, alleviates the operating pressure of motor, thereby saves the energy.
Can realize and increase balance weight or do not add balance weight or change the multiple choices such as size of balance weight by removably connecting of balance weight and hoist cable end, can adapt to flexibly various situations.
Fire door hoisting device of the present invention, by the each operating pressure that increases a balance weight and alleviate motor of the end at two hoist cables, simple and practical, save the energy.
