Abstract
The utility model discloses an electric roller shutter door, comprising a roller shutter door, a doorframe, a motor and a switch group, upper and lower limit switches of the switch group are both formed by a serial connection of two travel switches, the travel switches are respectively installed at upper and lower two sides of the doorframe, and form two groups of upper and lower limit switches. The electric roller shutter door in the utility model is advantaged by, via the two groups of upper and lower limit switches formed by a serial connection of two travel switches, guaranteeing that circuit can be turned off when the roller shutter door travels to a corresponding position, realizing function of the two groups of travel switches being backup to each other, providing dual limit protection to the electric roller shutter door, improving reliability of operation of the roller shutter door, and greatly reducing fault probability of reverse rolling and upward rolling, thereby reducing maintenance cost.
Description
Technical field
The utility model relates to a kind of electric rolling door, especially a kind of electric rolling door with dual position limitation protection function.
Background technology
Rolling door is that the door sheet with the multi-joint activity is cascaded, is installed in the fixing slideway of doorframe, and be that door is up and down rotated at the center with door top spool.Be applicable to public place or dwelling houses such as the commercial shop front, garage, market, hospital, industrial enterprise.Especially door opening is bigger, the effect of convenient, fast unlatching is played in the place of inconvenience installation ground door body, electric rolling door adopts driven by motor roller shutter central axis to rotate, the general hold function that adopts the bound bit switch of being located at the doorframe upper-lower position to realize motor, when rolling door arrives predeterminated position, thereby motor stops to realize opening and closing automatically of roller shutter automatically.
Limit switch belongs to mechanical switch, and the opening and closing of electric rolling all need its precision maneuver, causes the switch loose contact in case any one breaks down or uses for a long time, and rolling door all can produce fault, and common faults is as follows:
1, upper limit fault, rolling door will go up volume can't be descending;
2, lower limit fault, rolling door will be rewinded, and rolling door is damaged.
The generation of above fault gently then makes rolling door lose efficacy, and the serious rolling door that may make is badly damaged.
The utility model content
At above defective, the purpose of this utility model provides a kind of electric rolling door, can effectively solve the problem of above existence.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electric rolling door comprises rolling door, doorframe, and motor and switches set, switches set comprise the upper and lower limit bit switch, described switches set comprises at least two group upper and lower limit bit switches.
Preferably, the upper and lower limit bit switch of described switches set series connection.
Preferably, described limit switch adopts travel switch, is installed on the both sides up and down of doorframe respectively.
Preferably, Dui Ying upper limit travel switch and lower limit travel switch are provided with at the wrong row of vertical direction.
Electric rolling door with dual position limitation protection function described in the utility model; by adopting two travel switches to be composed in series two groups of bound bit switches; two groups of mutually redundant functions of travel switch have been realized; circuit can disconnect when guaranteeing that rolling door runs to the relevant position; for electric rolling door provides dual position limitation protection; improved the rolling door reliability of operation, can reduce the fault probability of rewinding, going up volume greatly, thereby reduce maintenance cost.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the composition structure chart of electric rolling door one specific embodiment described in the utility model;
Fig. 2 is the electric realization schematic diagram of the control system of the described electric rolling door of embodiment.
Among the figure:
1, rolling door; 2, doorframe; 3, motor; 41,42, upper limit travel switch;
51,52, lower limit travel switch.
The specific embodiment
As shown in Figure 1, provided the composition structure chart of electric rolling door one specific embodiment described in the utility model.Comprise rolling door 1 its whole composition, doorframe 2, and motor 3 and switches set, the upper limit position switch of wherein said switches set is composed in series by upper limit travel switch 41,42; Lower position switch is composed in series by lower limit travel switch 51,52.
Upper limit travel switch 41,42 is installed on the both sides, top of doorframe, is provided with at the wrong row of vertical direction; Lower limit travel switch 51,52 is installed on the both sides, below of doorframe, is provided with at the wrong row of vertical direction equally.Upper limit travel switch 41 constitutes two groups of upper and lower limit bit switches with lower limit travel switch 51, upper limit travel switch 42 respectively with lower limit travel switch 52.
With the three-phase squirrel cage motor is example, the electric realization principle of the control system of above-mentioned electric rolling door as shown in Figure 2, the air switch QF that closes connects three phase mains, press the forward SB1 that releases the button, the closed motor power of connecting of contactor KM1 coil electricity adhesive KM1 main contact, the operation of motor forward, rolling door is opened, when moving to upper limit travel switch 41 or 51 places, link stopper impact stroke switch, the constant close contact of corresponding SQ1 or SQ1 ' disconnects, contactor KM1 outage, main contact discharges, and motor stops, and rolling door stops to go up volume; If press reverse X button SB2, the closed motor power of connecting of contactor KM2 coil electricity adhesive KM2 main contact, the motor inverted running, rolling door is closed, when moving to lower limit travel switch 42 or 52 places, link stopper impact stroke switch, the constant close contact of corresponding SQ2 or SQ2 ' disconnects, contactor KM2 outage, main contact discharges, motor stops, and rolling door stops to transfer, and finishes closing of rolling door.
By adopting two travel switches (SQ1 and SQ1 '), (SQ2 and SQ2 ') to be composed in series two groups of bound bit switches; two groups of mutually redundant functions of travel switch have been realized; circuit can disconnect when guaranteeing that rolling door runs to the relevant position; for electric rolling door provides dual position limitation protection; improved the rolling door reliability of operation; can reduce the fault probability of rewinding, going up volume greatly, thereby reduce maintenance cost.
The advantage that more than shows and described principal character of the present utility model and had; the technician of the industry should understand; the utility model is not restricted to the described embodiments; the utility model also has some variations and improves under the prerequisite that does not break away from the utility model purport and scope; as change the pattern of travel switch; adopt dissimilar motor etc., these changes and improvements all fall in the claimed scope of the utility model.
