Abstract
The utility model relates to an automatic furnace-door shutting and compressing device comprising a furnace body. A furnace-door compressing guide wheel plate is arranged on the upper end of the right side of the furnace body. A furnace-door compressing guide wheel is arranged under the furnace-door compressing guide wheel plate. The furnace-door compressing guide wheel is sequentially connected through a furnace-door shaft with a spring, a furnace-door compressing cylinder, a furnace-door compressing guide roller and a furnace-door compressing guide plate. A furnace-door opening cylinder is arranged at the left end of the furnace-door compressing guide plate. The furnace-door opening cylinder is connected with a furnace door through a connecting piece. The automatic furnace-door shutting and compressing device has the advantages of simple structure and convenience in furnace-door opening and compressing.
Description
Technical field
The utility model relates to a kind of machine components, particularly a kind of fire door autoshutdown hold down gag.
Background technology
In Equipment for Heating Processing, the sealing of fire door can guarantee the control of temperature in stove, prevents the waste of energy, prevents the injury of scattering and disappearing the operator being caused of pernicious gas.The opening ways of fire door has lift, and is articulated.General massive fire door lift, with motor or air cylinder driven, small-sized use is articulated, manually push-and-pull.But the heating furnace of some type of furnace such as positive plate, the type of furnace is high, is not suitable for lift, can only use hinge type, but the too large unlatching of fire door difficulty very.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, opens fire door autoshutdown hold down gag easily.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: this fire door autoshutdown hold down gag, comprise body of heater, upper end, described body of heater right side is provided with fire door and compresses idler plate, described fire door compresses idler plate and is arranged with fire door compression guide wheel, described fire door compresses guide wheel and is connected with spring, fire door clamping cylinder, fire door compression deflector roll and fire door compression guide plate in turn by the fire door axle, described fire door compresses the guide plate left end and is provided with door opened cylinder, and described door opened cylinder is connected with fire door by connector.
Compared with prior art, usefulness of the present utility model is: this fire door autoshutdown hold down gag is simple in structure, makes the unlatching of fire door and seals simple and convenient.
Description of drawings:
Fig. 1 is the structural representation of the utility model fire door autoshutdown hold down gag.
In figure: 1, body of heater; 2, fire door compresses idler plate; 3, fire door compresses guide wheel; 4, fire door axle; 5, spring; 6, fire door clamping cylinder; 7, fire door compresses deflector roll; 8, fire door compresses guide plate; 9, connector; 10, door opened cylinder.
The specific embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of fire door autoshutdown hold down gag shown in Figure 1, comprise body of heater 1, described body of heater 1 upper end, right side is provided with fire door and compresses idler plate 2, described fire door compresses idler plate 2 and is arranged with fire door compression guide wheel 3, described fire door compresses guide wheel 3 and is connected with spring 5, fire door clamping cylinder 6, fire door compression deflector roll 7 and fire door compression guide plate 8 in turn by fire door axle 4, described fire door compresses guide plate 8 left ends and is provided with door opened cylinder 10, and described door opened cylinder 10 is connected with fire door by connector 9.
Operation principle according to the above embodiment fire door autoshutdown hold down gag is:
Respectively be provided with a door opened cylinder 10 in the both sides of body of heater, in the time will closing fire door, door opened cylinder 10 successively reaches the position in order, door opened like this cylinder 10 is just shifted fire door onto position by fire door connector 9, although fire door has at this moment put in place, but not tight with body of heater 1 sealing, will rely on fire door clamping cylinder 6 to open the compression fire door.the fire door clamping cylinder starts, because the top of fire door clamping cylinder 6 is connected with spring 5, and the bottom does not arrange, the fire door compression guide wheel 3 that fire door clamping cylinder 6 starts rear lower compresses the fire door end opening gradually along fire door compression idler plate 2, at this moment the fire door on fire door axle 4 compresses deflector roll 7 and also compresses guide plate 8 along fire door the fire door middle part is compressed, in fire door bottom and the middle process that compresses, top fire door compresses guide wheel 3 and also compresses idler plate 2 gradually with fire door compression suitable for reading along fire door, after fire door upper and lower opening and middle the compression, the fire door sight alignment, whole fire door is closely sealed mutually with body of heater 1.
This fire door autoshutdown hold down gag is simple in structure, makes the unlatching of fire door and seals simple and convenient.
It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
