Abstract
The utility model discloses a large furnace lid lifting mechanism. The large furnace lid lifting mechanism comprises a supporting frame and a supporting shaft, wherein the supporting frame and the supporting shaft are arranged on the side wall of a furnace body. A speed reducer and chain wheels are arranged on the supporting frame. The speed reducer is connected with a chain meshed with the chain wheels. One end of the chain is connected with a furnace cover. When the large furnace lid lifting mechanism is used, the speed reducer drives the chain wheels and the chain to move so that the chain can drive the furnace cover to rise and fall, and the supporting frame and the supporting shaft do not rise or fall. Due to the adoption of the method, the furnace cover stably and reliably rises and falls, no problem of the service life exists, the speed can be increased and decreased through the speed reducer, and the problem that a traditional furnace cover lifting mechanism can not meet the requirement for rapidly lifting the furnace cover under the conditions such as quenching can be solved.
Description
Technical field
The utility model relates to a kind of elevating mechanism, refers to especially a kind of large-scale pit type furnace covers elevating mechanism.
Background technology
Tradition bell elevating mechanism is that Worm gear feed screw lift promotes lifting shaft drive furnace cover lifting; the top that is connected in lifting shaft by support due to bell produces larger cantilever moment; rigidity to lifting shaft and the performance requirement of reductor are very high; when use, often there will be because of the rigidity of lifting shaft cause not furnace cover lifting shake not steadily, even can not lifting; the generation of the problem such as reductor Worm gear feed screw serious wear, service life are short; and bell is larger, the problems referred to above are just more serious.
Utility model content
The utility model is for deficiency of the prior art, and object is to provide one can make furnace cover lifting steadily, reliably, and speed is adjustable, without the large-scale bell lifting structure of problem in service life.
The technical solution of the utility model is achieved in that large-scale bell elevating mechanism, be arranged on the bell on body of heater in order to lifting, comprise the bracing frame and the back shaft that are arranged on sidewall of the furnace body, support frame as described above is provided with reductor and sprocket wheel, this reductor is connected with the chain with sprocket engagement, and one end of this chain is connected with bell.
Further, described sprocket wheel is positioned at the top of above-mentioned bell.
Further, described reductor is turbine worm reducer.
Further, described reductor shaft connects motor.
The utility model is compared with prior art: when use, by reductor drive sprocket and chain movement, make chain-driving furnace cover lifting, and bracing frame and back shaft are not done elevating movement, adopt this kind of mode, furnace cover lifting is steadily reliable, without problem in service life, and can carry out speed adjusting to speed by reductor, can realize traditional bell elevating mechanism and can not meet the requirement of rise bell fast of the situation needs such as quenching.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in attached Fig. 1 and 2, large-scale bell elevating mechanism, in order to lifting bell 2, this bell 2 is large-scale well formula glowing furnace, well formula tempering furnace, the bell 2 arranging in other Large Furnace such as spheroidizing annealing furnace, it comprises the bracing frame 31 and the back shaft 32 that are arranged on body of heater 1 sidewall, in order to support bell 2, it can be also cylinder that support frame as described above 31 is provided with reductor 33() and sprocket wheel 34, described reductor 33 axles connect motor 4, described sprocket wheel 34 is positioned at the top of described bell 2, this reductor 33 is connected with the chain 35 engaging with sprocket wheel 34, one end of this chain 35 is connected with bell 2.Wherein this reductor 33 is turbine worm reductor or gear reduction unit.
Compared with traditional elevating mechanism, when use, move by reductor 33 drive sprockets 34 and chain 35, make chain 35 drive bell 2 liftings, and bracing frame 31 and back shaft 32 are not done elevating movement, adopt this kind of mode, bell 2 liftings are steadily reliable, without problem in service life, and can carry out speed adjusting to speed by reductor 33, the elevating mechanism that can realize traditional bell can not meet the requirement of rise bell fast of the situation needs such as quenching.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
