Abstract
A kind of dust catcher dropproof twice, including a fall arrest system being installed on collision baffle plate and the secondary fall-proofing device being installed on universal wheel.In the normal operating conditions of dust catcher, dust catcher traveling road conditions are judged by a fall arrest system, and transmit a signal to control system, by control system according to the signal transmitted, dust catcher is driven to move ahead, turning backward, it is further continued for moving ahead, but when obvious high low head occurs in ground, and a fall arrest system of dust catcher does not make effecting reaction, universal wheel is caused to completely disengage ground, at this moment, secondary fall-proofing device is triggered, force dust catcher out of service, dust catcher security in use is effectively improved with this.
Description
Technical field
The present invention relates to a kind of intellective dust collector, more particularly to a kind of intellective dust collector dropproof twice.
Background technology
In current intellective dust collector market, many dust catchers all carry dropproof function, but extreme portions dust catcher
Only band once dropproof function, the fall-proofing device that road conditions are judged using infrared probe such as generally used, but
This mode can be judged by accident by the interference of some strong light, and require higher occasion dropproof, such as with two layers
In use, such as slightly mistake in the house of flooring, dust catcher falls in stairs port causes furniture to damage, and even falls and makes
Into the accident for the personnel that injure, therefore dust catcher security seems extremely important.
The content of the invention
For these reasons, we have developed a kind of dust catcher dropproof twice.
A kind of dust catcher dropproof twice, including be installed on the fall arrest system collided on baffle plate and be installed on ten thousand
To the secondary fall-proofing device on wheel.
A fall arrest system being installed on collision baffle plate, include and be respectively arranged in collision baffle plate front portion, it is left
Portion and the detector and control system of right part, the detector include transmitter and receiver, passed through when transmitter sends signal
Ground return, when receiver receives reflected signal, the control system will continue to drive dust catcher to move ahead, as transmitter is sent
Signal, receiver can not receive background return, and at this moment control system will drive dust catcher to retreat and turn to, before then proceeding to
OK.
The secondary fall-proofing device being installed on universal wheel, is mechanical fall-proofing device, including universal wheel, wheel shaft,
Guide sleeve, spring, clamp button of the spring and microswitch, the universal wheel are fixed together with wheel shaft, and the wheel shaft can led
Moved up and down into set, the guide sleeve, which is screwed, to be connected in dust catcher frame, the spring by clamp button of the spring with
The drive rod of the microswitch links together, and when universal wheel keeps contacting with ground, the spring is in vacuum cleaner body
In the presence of weight, in compressive state, spring has a upward thrust to the drive rod of microswitch, and microswitch moves
Contact is pressed into, and now microswitch is in and electrically connects state, dust catcher normal work；And when universal wheel and ground depart from,
Wheel shaft and universal wheel move down in the presence of own wt and spring force, when the drive rod of microswitch is fully opened
When, movable contact ejection, microswitch enters off-position, and dust catcher is out of service.
The secondary fall-proofing device being installed on universal wheel, can also be universal wheel, Universal castor, spring, gland
And microswitch, the universal wheel are connected on Universal castor, the Universal castor can move up and down in dust catcher frame, institute
State gland and be screwed and be connected on Universal castor, gland closely connects with the fixed contact on the drive rod of the microswitch
Touch, when universal wheel keeps contacting with ground, Universal castor is in upper limit position with gland, and spring is compressed, microswitch
Drive rod is in nature open mode, dust catcher normal operation；When universal wheel and ground depart from, universal wheel and Universal castor are in bullet
Under spring force and self gravitation effect, moved down along dust catcher frame, Universal castor moves down with gland, tight with gland
The tactile drive rod of contiguity is depressed therewith, until the movable contact of microswitch is pressed into, microswitch enters off-position, dust suction
Device is out of service.

Embodiment
Below in conjunction with the accompanying drawings, technical scheme is described in detail, so as to be done to protection scope of the present invention
Go out apparent clearly to define.
Embodiment one
Such as accompanying drawing 1-3, a kind of dust catcher dropproof twice, including a fall arrest system being installed on collision baffle plate 18 and
The secondary fall-proofing device being installed on universal wheel 11, a fall arrest system being installed on collision baffle plate 18, comprising
It is anterior to be respectively arranged in collision baffle plate, the detector 19 and control system of left part and right part, the detector 19, which includes, to be launched
Device and receiver, when transmitter sends signal by ground return, when receiver receives the reflected signal, the control system
It will continue to drive dust catcher to move ahead, as transmitter sends signal, receiver can not receive background return, at this moment control system
Dust catcher will be driven to retreat, turn to, be further continued for moving ahead.
The secondary fall-proofing device being installed on universal wheel 11, is mechanical fall-proofing device, including universal wheel 11, wheel
Axle 12, guide sleeve 14, spring 15, clamp button of the spring 16 and microswitch 17, the universal wheel 11 are fixedly connected on one with wheel shaft 12
Rise, the wheel shaft 12 can move up and down in guide sleeve 14, and the guide sleeve 14, which is screwed, is connected to dust catcher frame 13
On, the spring 15 is linked together by the drive rod 171 of clamp button of the spring 16 and the microswitch 17, when universal wheel 11 with
When ground contacts, spring 15 is in the presence of vacuum cleaner body weight, in compressive state, drive of the spring 15 to microswitch 17
Lever 171 has a upward thrust, and the movable contact 172 of microswitch 17 is pressed into, and now microswitch 17 is in and electrically connected
State, dust catcher normal work；And when universal wheel 11 and ground depart from, wheel shaft 12 and universal wheel 11 are in own wt and spring
Moved down in the presence of power, until the drive rod 171 of microswitch 17 is fully opened, movable contact 172 ejects, microswitch
17 enter off-position, and dust catcher is out of service.
Embodiment two
Such as accompanying drawing 4-6, the height of this dust catcher is very low, and inner space is more narrow, as secondary anti-in embodiment one in used
Falling device, it is clear that insufficient height.
A kind of dust catcher dropproof twice, including be installed on the fall arrest system collided on baffle plate 28 and be installed on
Secondary fall-proofing device on universal wheel 21 a, fall arrest system being installed on collision baffle plate 28, includes difference
It is anterior to be installed on collision baffle plate, the detector 29 and control system of left part and right part, the detector 29 include transmitter and connect
Device is received, when transmitter sends signal by ground return, when receiver receives the reflected signal, the control system will continue
Dust catcher is driven to move ahead, as transmitter sends signal, receiver can not receive background return, and at this moment control system will drive
Dust catcher is retreated, turned to, and is further continued for moving ahead.
The secondary fall-proofing device being installed on universal wheel 21, there are universal wheel 21, Universal castor 22, spring 23, pressure
