Abstract
The invention discloses using two methods, duplicate protection is carried out, is made anti-fall more effective：It is that artificial maloperation is prevented by circuit control first, circuit is disconnected using relay when overhead door rises, ensure under gate open state, once closing anti-fall device arm, disconnecting declines button power supply by relay at this time makes button be in off state, touch the button at this time invalid it is possible to prevente effectively from artificial maloperation, anti-fall arm is only opened button could normal use.Secondly, when anti-fall arm closes, timely gate, which falls, can also be blocked in midair, be unlikely to pound object or normal person.The present invention is easy to operate simple, improves security performance, highly practical.
Description
Technical field
The present invention is applicable in industrial overhead door, is controlled circuit using relay, rotating arm falls on the door to be controlled.
Background technology
Automatic overhead door between industrial truck, vehicles passing in and out and personnel are more, and it is high that gate lifts frequent frequency of use.Electrically operated gate
In lifting process or when resting on top, since workshop vibrates, component wear, motor brake failure, door-hinge fracture or steel wire
The reasons such as fracture of rope may all cause gate to fall, and smash vehicles passing in and out, extremely dangerous.
Invention content
The purpose of the present invention is being directed to insufficient and security risk existing for existing overhead door, installing overhead door anti-fall device additional can
Artificial maloperation is avoided to effectively prevent gate to fall, by gate gate falls the anti-fall device on two side slideways
Gear is in midair to avoid smashing vehicles passing in and out.
Technical solution：It is of the present invention solve the problems, such as used by there are two types of methods, carry out duplicate protection, make anti-fall more effective：
It is that artificial maloperation is prevented by circuit control first, i.e., is disconnected circuit using relay when overhead door rises, it is ensured that is big
Under door open state, once closing anti-fall device arm, disconnecting declines button power supply by relay at this time makes button be in open circuit
State touches the button invalid it is possible to prevente effectively from artificial maloperation, anti-fall arm is only opened button could normal use at this time.Its
Secondary, when anti-fall arm closes, timely gate, which falls, can also be blocked in midair, be unlikely to pound object or normal person.
Preferably, relay can effective control circuit.
Preferably, anti-fall arm is closed freely.
Preferably, oblique pull iron chains protects anti-fall arm, prevent the impact force that gate falls is excessive from smashing anti-fall arm.
Advantageous effect：The invention has the advantages that：Artificial maloperation can be effectively prevent to cause through the invention
Overhead door falls and can be kept off in midair overhead door falls.
Description of the drawings：
Fig. 1 is schematic structural view of the invention.
Fig. 2 is that overhead door falls hit current vehicle photo suddenly
Fig. 3 is the photo of overhead door anti-fall device opening state, and overhead door can be lifted normally.
Fig. 4 is the photo of overhead door anti-fall device closed state, overhead door can be effectively prevent to fall.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present invention is with inventive technique side of the present invention
Implemented under premised on case, it should be understood that examples are only for illustrating the present invention and not for limiting the scope of the present invention.
As shown in Figure 1, overhead door anti-fall device, it includes material often to cover materials：1 relay, 1 diameter are 20 millimeters long
The threaded axis with nut in 200 millimeters of both ends is spent, 1 root long degree is the iron chains of 8 millimeters of 700 mm dia, 3 50*50*300 millis
The square tube of rice, 1 50*50*150 millimeters of square tube；The steel plate in 1 piece of 2*60*80 mm band, 4 holes, the screw of 4 cuff nuts.
Often fan overhead door needs 2 sets, each 1 set of left and right.
Production method：On the steel construction pillar close to overhead door two side slideway, choosing is fixed apart from 2 meters of ground place
The upper bracket 1 made with two 300 millimeters of long square tubes and the electric welding of lower bracket 2 are fixed on steel construction pillar by point, away from 1,
Each 1 diameter, 20 millimeters of corresponding holes of making a call to install 1 for installation axle 5 among 1,2 holders about 2 50 millimeters of holder opening ends
A L-type lever arm (straight-arm 3 grows 300 millimeters, and connecting lever 4 grows 150 millimeters), it is contemplated that impact force when gate falls, with 8 milli of diameter
End is simultaneously fixed on steel construction pillar by the anti-fall arm of 6 upward oblique pull of iron chains of rice.After overhead door rises, anti-fall arm is closed
Across on slideway, if gate falls, the anti-fall arm in both sides will block.1 stent ends burn-on steel plate 7 for install 1
Relay 8 is simultaneously connected in gate declines button circuit by relay 8, and when lever arm closes, relay cuts off declines button
Power supply will not decline pressing declines button gate at this time, avoid artificial maloperation, only move lever arm from slideway
Gate could be closed after opening.The present invention is simple to operate, improves safety, highly practical.
Above-mentioned specific implementation mode is a preferred embodiment of the present invention, is not the implementation for limiting the present invention
The equivalence changes made with right, the content described in all ranges of patent protection according to the present invention and modification,
It should all be included within the scope of present patent application.
