A kind of bell jar lifting resistance furnace
Technical field
The utility model belongs to heating device technology area, particularly a kind of industrial bell jar lifting resistance furnace of workpiece being heat-treated usefulness.
Background technology
At present to big-and-middle-sized workpiece, particularly the resistance furnace of heat-treating than farm labourer's part mostly is body of heater is fixed, the fire door lift, it is bell shape body of heater lift that minority is arranged, and chassis in service drives into along the body of heater length direction, heat-treats the back and leaves in the other direction.Its shortcoming is that floor space is big; Chassis drives that to leave stroke oversize into, and time-consuming many, production efficiency is low, and energy dissipation simultaneously is big.Bell shape body of heater lift resistance furnace body of heater directly is connected with hydraulic ram, can not finely tune with chassis.
The utility model content
The bell jar lifting resistance furnace that provides a kind of floor space little is provided the utility model purpose.
For addressing the above problem, the utility model adopts following technical scheme: a kind of bell jar lifting resistance furnace, comprise body of heater, body of heater is connected with hydraulic ram, hydraulic ram vertically is installed on the raising legs, also includes chassis, and the pallet bottom both sides are equipped with some to wheel along its length, wheel is axially identical with the chassis length direction, and wheel is set up on the track.
Two pairs of wheels are two-wheel edge wheel in the middle of the pallet bottom, and wheel shaft drives with two cover driving mechanisms.
Hydraulic ram is connected with raising legs by the cross adjustable shelf.
Be provided with guiding mechanism between chassis two ends and the raising legs, bell jar and chassis contact site place mat seal felt.
In the utility model, the pallet bottom both sides are equipped with some to wheel along its length, and wheel is axially identical with the chassis length direction, and wheel is set up on the track.Chassis laterally drives into and leaves body of heater in the use, does not resemble to drive into along the chassis length direction originally to leave, and floor space reduces naturally; It is short that chassis drives the time of leaving into, and the time spent is few, the production efficiency height; The body of heater waiting time is short, and thermal waste is few.More highlight its advantage to often carrying out than the stove that farm labourer's part is handled.Be connected with the cross adjustable shelf between hydraulic ram and the body of heater, the body of heater activity hangs on the hydraulic ram, can adjust with chassis, remains to seal between body of heater and the chassis to contact.

Embodiment
Embodiment, a kind of bell jar lifting resistance furnace comprise bell shape body of heater 4, chassis 5.Bell shape body of heater 4 tops are that truss-frame structure, bottom are body structure, and building in the casing has refractory fiber blanket furnace lining 11,12 for being installed in the electrical heating element on the furnace wall.Be connected with 4 hydraulic rams 3 above the body of heater 4, hydraulic ram 3 is connected with raising legs 1 by cross adjustable shelf 10, can freely swing.Raising legs 1 is formed by shaped steel weldering system.Chassis 5 is formed by shaped steel weldering system, build a plurality of stamp mass piers 14 that insulating brick arranged and place parallels 13 in the car body, chassis 5 two bottom sides are equipped with some to wheel along its length, and middle two pairs of wheels 8 are two-wheel edge wheel, other wheels 6 are flat wheel, and wheel shaft drives with two cover driving mechanisms 9.Wheel is axially identical with the chassis length direction, and wheel 6,8 is set up on the track 7.Body of heater 4 and chassis 5 contact site place mat sealing fibrefelts 15.Be provided with guiding mechanism 2 between chassis 5 two ends and the raising legs 1, guiding mechanism is formed by being installed in grooved rail on the raising legs and the slide plate on the chassis both ends of the surface in the present embodiment.
