Abstract
The utility model relates to a furnace door lifting appliance for a car-type heat treating furnace, which comprises a furnace door body, an outer frame and a lifting mechanism. A driving wheel and a driven wheel are respectively arranged at both sides of the top of the outer frame and are respectively meshed with a driving chain; the top of the outer frame is connected with both sides of the furnace door body by the lifting mechanism; a limit block is arranged between the driving wheel and the driven wheel; and meanwhile, two supporting wheel mechanisms are respectively arranged at both sides of the frame at the bottom side of the furnace door body. The furnace door lifting appliance has the benefits that by the hydraulic lifting mechanism which is arranged on the furnace door body and is beneficial for effectively implementing the lifting and descending operation of a furnace door, the continuous working stability of the furnace door can be improved, the furnace door is convenient to operate and regulate and the quality of castings can be improved; and meanwhile, the furnace door lifting appliance is also beneficial for ensuring the integral leakproofness of the heat treating furnace.
Description
Technical field
The utility model relates to the heat treatment furnace technology, relates in particular to a kind of fire door lifting gear that is used for car-type heat treating furnace.
Background technology
Present tradition periodically heat treatment furnace comprises Scale Bell-type Heat Treatment Furnace and car-type heat treating furnace etc.; For car-type heat treating furnace; Furnace bottom can move and tumble; Can directly the foundry goods that is processed be transported under the point of destination hypsokinesis dumping such as quenching tank from heating chamber easily, this just needs fire door to cooperate body of heater to go up and down neatly.Simultaneously; The furnace sealing of a lot of car-type heat treating furnaces is bad, the fire door framework is unreasonable; Especially rely on manual or simple and easy physical construction to realize the fire door part of up-down for some one; Lack continuous firing stability, be not easy to operation and regulate, be difficult to realize continuous normal operation, this can cause disadvantageous effect to the physicals after the heat treating castings equally.Therefore; Be that traditional car-type heat treating furnace or traditional Scale Bell-type Heat Treatment Furnace all can not fully satisfy present requirement to the less energy-consumption of periodicity heat treatment furnace, high insulation, high efficiency; To above aspect, need partly reasonably improve existing fire door.
The utility model content
To above defective, the utility model provides a kind of stability that improves the fire door continuous firing, is convenient to operate and regulate, can improve the fire door lifting gear that is used for car-type heat treating furnace of casting product quality, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of fire door lifting gear that is used for car-type heat treating furnace; Comprise fire door body, outside framework and lifting mechanism; Both sides, said outside framework top are installed motion-work wheel and follow-up pulley and two respectively and are taken turns respectively and mesh with driving chain; The outside framework top is connected with fire door body both sides through lifting mechanism, between motion-work wheel and follow-up pulley, is provided with limited block; Simultaneously, a wheel holding mechanism is respectively installed in the framework both sides that are positioned at fire door body bottom side.
In addition, said lifting mechanism is made up of balancing weight, motion-work wheel, limited block and follow-up pulley.
The described beneficial effect that is used for the fire door lifting gear of car-type heat treating furnace of the utility model is: through the hydraulic lifting mechanism that is beneficial to effective realization fire door descending operation is installed on the fire door body, can improve the fire door continuous firing stability, be convenient to operation and regulate, can improve casting product quality; Simultaneously, also help guaranteeing the whole stopping property of heat treatment furnace.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said fire door lifting gear of the utility model embodiment;
Fig. 2 is the hydraulic cylinder part synoptic diagram of the said fire door lifting gear of the utility model embodiment.
Among the figure:
1, fire door body; 2, outside framework; 3, lifting mechanism; 4, balancing weight; 5, motion-work wheel; 6, limited block; 7, follow-up pulley; 8, wheel holding mechanism; 9, cylinder top connection; 10, upper cylinder joint; 11, cylinder.
Embodiment
Shown in Fig. 1-2; The described fire door lifting gear that is used for car-type heat treating furnace of the utility model embodiment; Comprise fire door body 1, outside framework 2 and lifting mechanism 3; Lifting mechanism 3 wherein is made up of balancing weight 4, motion-work wheel 5, limited block 6 and follow-up pulley 7, both sides, said outside framework 2 top install respectively motion-work wheel 5 and follow-up pulley 7 and two take turns respectively with the driving chain engagement to realize the drive connection of the two, outside framework 2 tops are connected with fire door body 1 both sides through lifting mechanism 3; A said driving chain wherein end is equipped with balancing weight 4, between motion-work wheel 5 and follow-up pulley 7, is provided with limited block 6; Simultaneously, a wheel holding mechanism 8 is respectively installed in the framework both sides that are positioned at fire door body 1 bottom side; In addition, said outside framework 2 bottoms are provided with cylinder 11 and are furnished with upper cylinder joint 10, be positioned at cylinder 11 opposite side correspondences cylinder top connection 9 is set.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
