Abstract
The utility model relates to a fire-resisting rolling shutter door, in particular to a double-protection fire-resisting rolling shutter door with upper limit and lower limit. The fire-resisting rolling shutter door is installed on a wall and driven by a fire-resisting rolling shutter motor to operate, a limit switch is arranged in the fire-resisting rolling shutter motor, the fire-resisting rolling shutter motor and the limit switch are connected with a fire-resisting rolling shutter controller respectively, and the fire-resisting rolling shutter controller is connected with a control button. The fire-resisting rolling shutter motor is provided with the limit switch, the limit switch is accessed into the fire-resisting rolling shutter controller, and a mechanical gear triggers the limit switch to stop the fire-resisting door. The fire-resisting rolling shutter controller and the limit switch have double controlling effects, during normal work, the fire-resisting rolling shutter controller studies vertical movement time of the fire-resisting rolling shutter door automatically, after the study, the fire-resisting rolling shutter controller has memory, when the limit switch is poor in contact, the controller does not receive limit signals, chips can stop the door automatically within 100 to 300 milliseconds, and double protection effects of the fire-resisting rolling door are obtained.
Description
Technical field
The utility model relates to a kind of fire resistance rolling shutter door, is specially a kind of spacing duplicate protection fire resistance rolling shutter door up and down.
Background technology
Fire resistance rolling shutter door is mainly used in the public place that there is the fire-fighting requirement in large supermarket (hypermarket), megastore, large-scale specialized material market, large-scale museum, factory building, warehouse etc.When fire alarm took place, fire resistance rolling shutter door put down (descending) by predefined program automatically under the control of fire-fighting central control system, thereby reached the effect that stops flame to spread to other scopes, strove for valuable time for implementing fire-fighting fire extinguishing.But because the particularity of fire resistance rolling shutter door; Can not open often, and limit switch to be two copper sheets trigger, easy oxidation of long duration; Cause loose contact; Like this when emergency, situation about can't open may appear, and such situation can cause heavy losses to people's lives and properties.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide a kind of technical scheme of spacing duplicate protection fire resistance rolling shutter door up and down, can in case of emergency guarantee the normal operation of fire resistance rolling shutter door.
Described spacing duplicate protection fire resistance rolling shutter door up and down; This fire resistance rolling shutter door is installed on the body of wall; Fire resistance rolling shutter door is moved by the fire curtain driven by motor; It is characterized in that: be provided with limit switch in the fire curtain motor, the fire curtain motor links to each other with the fire curtain controller respectively with limit switch, and the connection of fire curtain controller is provided with control button.
Described spacing duplicate protection fire resistance rolling shutter door up and down is characterized in that the mechanical gear interoperation in described limit switch and the fire curtain motor.
Described spacing duplicate protection fire resistance rolling shutter door up and down is characterized in that described fire curtain controller links to each other with the fire curtain motor through the interior relay of establishing.
Described up and down spacing duplicate protection fire resistance rolling shutter door is characterized in that described fire curtain controller can learn the running time up and down of fire resistance rolling shutter door automatically.
The utlity model has following advantage: 1. the fire curtain motor carries limit switch, and limit switch inserts in the fire curtain controller, triggers limit switch by mechanical gear and stops labeled door; 2. the dual control of fire curtain controller and limit switch; During operate as normal, the fire curtain controller learns to calculate moving up and down the time of fire resistance rolling shutter door automatically, and study finishes back fire curtain controller has just had memory; During the limit switch loose contact; Controller is not received limit signal, and chip can let door stop in 100 milliseconds to 300 milliseconds automatically, has played the double protection of fire resistance rolling shutter door.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-fire resistance rolling shutter door; The 2-body of wall; The 3-limit switch; 4-fire curtain motor; The 5-three phase mains; 6-fire curtain controller; The 7-control button.
The specific embodiment
Below in conjunction with Figure of description the utility model is further specified:
Spacing up and down duplicate protection fire resistance rolling shutter door, this fire resistance rolling shutter door 1 is installed on the body of wall 2, and fire resistance rolling shutter door 1 drives operation by fire curtain motor 4; Fire curtain motor 4 links to each other with fire curtain controller 6 through the relay of establishing in the fire curtain controller 6, and fire curtain controller 6 is controlled the operation of fire curtain motor 4 through the break-make of control relay.
In fire curtain motor 4, be provided with limit switch 3; Limit switch 3 has two copper sheets to trigger; Mechanical gear interoperation in limit switch 3 and the fire curtain motor 4 is not if limit switch 3 itself has fault, when last or when arriving stroke down; Fire resistance rolling shutter door 1 can be out of service automatically, and this is the first heavily protection of the utility model.
Limit switch 3 links to each other with fire curtain controller 6 simultaneously; When rolling door was normally moved, fire curtain controller 6 can be learnt rolling door automatically from closing to the time of opening, and study finishes the back controller has just had memory; During limit switch 3 loose contacts; If the start-up control button in 7 a period of times fire curtain controller 6 do not receive limit signal, fire curtain controller 6 can let door stop in 100 milliseconds to 300 milliseconds automatically, this is the second heavily protective effect of fire resistance rolling shutter door.
Three phase mains 5 directly connects into, and fire curtain controller 6 backs link to each other with fire curtain motor 4; The action of fire curtain motor 4 receives the control of fire curtain controller 6; Fire curtain controller 6 links to each other with control button 7, controls the control that button 7 is realized whole device.
Operation to control button 7 can be operated through the mechanical system operation or through remote control mode, and these are prior art all, repeat no more at this.
Claims (4)
1. spacing up and down duplicate protection fire resistance rolling shutter door; This fire resistance rolling shutter door is installed on the body of wall; Fire resistance rolling shutter door is moved by the fire curtain driven by motor; It is characterized in that: be provided with limit switch in the fire curtain motor, the fire curtain motor links to each other with the fire curtain controller respectively with limit switch, and the connection of fire curtain controller is provided with control button.
2. spacing duplicate protection fire resistance rolling shutter door up and down according to claim 1 is characterized in that the mechanical gear interoperation in described limit switch and the fire curtain motor.
