Description
Technical field
The present invention relates to a kind of open and close door gear of vertical hinged door, relate in particular to a kind of hydraulic buffer automatic vertical hinged door machine with power-failure close retaining force.
Background technology
At present, the automatic vertical hinged door machine of the domestic and international production of selling on the market mainly contains following two kinds: a kind of is the automatic vertical hinged door machine of mechanical reduction structure, this class door machine is realized the keying of door by motor-driven, do not have outage and close a confining force, applicable situation is restricted, and the open and close of door are by motor-driven.Another kind is the automatic vertical hinged door machine of all-hydraulic structure, and this class door machine drives the unlatching that realizes door by electricity, closes from energy storage.
This door machine mechanism complex structure is made the requirement on machining accuracy height, the manufacturing cost height, and noise is bigger.And the present invention has the characteristics of mechanical reduction structure and all-hydraulic structure automatic door, and the accuracy of manufacture and cost are low, are combined by commercial door closer and mechanical driving mechanism.Electricity drives the unlatching that realizes door, closes from energy storage, has outage and closes a confining force, and is applied widely.This machine is installed simple, has higher operability, practicality.
Summary of the invention
Technical problem to be solved by this invention is: a kind of automatic vertical hinged door machine that is combined by commercial door closer and mechanical driving mechanism is provided, with overcome a machine mechanism complexity, make the machining accuracy height, problems such as noise is big, no power-failure close retaining force.
The present invention is achieved in that and the present invention includes a machine, drive plate, roller, chute, and a door machine comprises that door closer, motor, machinery drive airplane hijacking structure and control system, and mechanical driving mechanism mainly comprises tooth bar, travelling gear, push rod and screw mandrel; The door machine is installed in the top of door leaf and is fixed on the doorframe, and drive plate one end links to each other with the output shaft of door closer, and the other end links to each other with the chute that is fixed on the door leaf upper end by roller.Door closer is commercial door closer, comprise tooth bar plunger, back-moving spring, choke valve, the tooth bar plunger engages in travelling gear on the output shaft and the door closer, back-moving spring one end is fixed on the machine, the other end stretches in the tooth bar plunger, and the tooth bar plunger fixedly can laterally move in the guide groove on the door machine.Its operating principle is: when opening the door, motor drives tooth bar by push rod and laterally moves, the travelling gear that rack drives is meshed with it rotates, travelling gear will rotatablely move and pass to the output shaft of door closer, output shaft will open the door transmission of power to door-hinge by drive plate, door leaf is opened, in the process of opening the door, output shaft can drive the tooth bar plunger movement (referring to Fig. 5) in the door closer simultaneously, and the tooth bar plunger compresses the back-moving spring in the door closer in the process that moves, and spring has been put aside elastic potential energy.After the process of opening the door is finished, because back-moving spring is compressed in the door opening process, the elastic potential energy of being put aside will be released, to promote the tooth bar plunger oppositely moves, driving output shaft when the tooth bar plunger moves rotates, output shaft will be closed the door transmission of power to door-hinge by drive plate, and office closes with door.According to the operating principle of door closer, the hydraulic oil of door closer inside will constitute resistance to the release of elastic potential energy of the spring, promptly reach the effect of buffering by throttling, and the speed of closing the door is under control.Two choke valves on the door closer can be regulated, and can control different rows Zhai section, a transformable speed of closing.In addition, because the back-moving spring in the door closer has certain precommpression, so after the door leaf closure, door leaf just has certain close retaining force.
Advantage of the present invention is: install simply, it is not high to make requirement on machining accuracy, highly versatile, and cost is lower, and has power-failure close retaining force, and its close retaining force is not influenced by outage.

The specific embodiment
The structural representation of embodiments of the invention as shown in Figure 1, 2, the described horizontal opening door machine of present embodiment comprises a machine 4, drive plate 7, roller 2, chute 3, door machine 4 comprises door closer 8, motor 14, mechanical driving mechanism and control system 15 among Fig. 3,4, and mechanical driving mechanism mainly comprises tooth bar 10, travelling gear 9, push rod 12 and screw mandrel 13; Door machine 4 is installed in the top of door leaf 6 and is fixed on the doorframe 1, and drive plate 7 one ends link to each other with the output shaft 18 of door closer 8, and the other end links to each other with the chute 3 that is fixed on door leaf 6 upper ends by roller 2.Control system 15 is identical with common horizontal opening door machine control system.Door closer 8 is commercial door closer, comprise tooth bar plunger 16, back-moving spring 17, choke valve 11, tooth bar plunger 16 engagements in travelling gear 9 on the output shaft 18 and the door closer 8, back-moving spring 17 1 ends are fixed on the machine 4, the other end stretches in the tooth bar plunger 16, and tooth bar plunger 16 fixedly can laterally move (referring to Fig. 5) in the guide groove on door machine 4.Its operating principle is: when opening the door, motor 14 drives tooth bar 10 by push rod 12 and laterally moves, tooth bar 10 drives travelling gear 9 ashamed the rotatablely moving that are meshed with it, the output shaft 18 that travelling gear 9 will rotatablely move and pass to door closer 8, output shaft 18 will open the door transmission of power to door-hinge 5 by drive plate 7, door leaf 6 is opened, in the process of opening the door, output shaft 18 can drive mobile (referring to Fig. 5) of the tooth bar plunger 16 in the door closer 8 simultaneously, and tooth bar plunger 16 compresses the back-moving spring in the door closer 8 17 in the process that moves, and spring has been put aside elastic potential energy.After the process of opening the door is finished, because back-moving spring 17 is compressed in the door opening process, the elastic potential energy of being put aside will be released, to promote tooth bar plunger 16 oppositely moves, driving output shaft 18 when tooth bar plunger 16 moves rotates, output shaft 18 will be closed the door transmission of power to door-hinge 5 by drive plate 7, and door leaf 6 cuts out.According to the operating principle of door closer, the hydraulic oil of door closer 8 inside will constitute resistance to the release of elastic potential energy of the spring, promptly reach the effect of buffering by throttling, and the speed of closing the door is under control.Two choke valves 11 on the door closer 8 can be regulated, and can control different rows journey section, a transformable speed of closing.In addition, because the back-moving spring 17 in the door closer has certain precommpression, so after door leaf 6 closures, door leaf 6 just has certain close retaining force, its close retaining force is not influenced by outage.
