Abstract
The utility model discloses a safety protection device for an electric revolving door and comprises an early warning switch arranged at the outside of a door jamb and a preventive device controlled by the early warning switch; wherein, the early warning switch enters into the early warning state when the revolving door turns to a preset distance from the door jamb, and gets rid of the early warning state when the revolving door turns outside the preset distance or is closed with the door jamb; the safety protection device for the electric revolving door has the advantages of simple structure and safe and reliable protection.
Description
Technical field
The utility model relates to a kind of protector, relates to particularly a kind ofly being used to prevent that the building electric rotating door from crushing pedestrian's electric rotating door safety device.
Background technology
At present, a lot of buildings are come in and gone out for being convenient for people to, and are provided with electric rotating door on the doorway.Because electric rotating door is being opened always---conversion between closing, in order to prevent that revolving door from pressing from both sides the people near closure state, usually be provided with downward optoelectronic switch at the revolving door top, when door is closed into to a certain degree, someone passes through the student, optoelectronic switch can be controlled electric rotating door and stop, thereby the situation of avoiding crushing the people occurs.But the hundreds of kilogram because revolving door generally weighs, if having the people to pass through when the approaching closure of door, revolving door is difficult in the short time braking and stops, thereby still can cause crushing even putting the generation of people's death condition sometimes.
The utility model content
The purpose of this utility model is at the problems referred to above, and electric rotating door safety device a kind of simple in structure, safe and reliable is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric rotating door safety device, the pre-protector that it is included in the outer early warning switch that is provided with of doorjamb and is controlled by the early warning switch, this early warning switch enters alert status when revolving door forwards to apart from doorjamb one setpoint distance, and removes alert status when closed outside setpoint distance or with doorjamb.
Described early warning switch is an optical inductor, this optical inductor is mounted on the outer column of doorjamb, described pre-protector is the electric rotating door check mechanism, and described optical inductor is connected in the braking circuit of described check mechanism with the limit switch of control revolving door apart from the doorjamb distance.
Described pre-protector is a roll guard, this roll guard is lifted on outside the doorframe and by motor-driven, described roll guard when the early warning switch connection and revolving door move in opposite directions, and when meeting, stop and when revolving door overlaps with doorjamb, returning original position with revolving door.
Because electric rotating door of the present utility model is being provided with early warning switch and pre-protector outdoors, and be in alert status at revolving door early warning switch when doorjamb enters setpoint distance, like this when the people is arranged by the early warning switch, the action of control and prevention protection unit, make revolving door have the sufficient time to protect in advance, can prevent that the situation that crushes the pedestrian from occurring, the revolving door security protection is more reliable.Adopt optical inductor and limit switch control check mechanism, it is simple in structure, and cost is low and safe and reliable.Adopting roll guard, is when revolving door enters certain zone, if there is the people to enter, by mobile in opposite directions roll guard with pedestrian's retaining outdoors, thereby play the security protection effect, its protection effect is relatively good.

The structural representation of the another kind of safety device of Fig. 3 the utility model.
Fig. 4 is a safety device control procedure schematic diagram shown in Figure 3.
Among the figure
1. revolving door 2. doorjambs 3. gratings 4. columns
5. roll guard
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 3, electric rotating door safety device of the present utility model, the pre-protector that it is included in the doorjamb 2 outer early warning switches 3 that are provided with and is controlled by early warning switch 3, this early warning switch 3 enters alert status when revolving door 1 forwards to apart from doorjamb 2 one setpoint distances, and removes alert status when closed outside setpoint distance or with doorjamb 2.
As shown in Figure 1 and Figure 2, described early warning switch is an optical inductor, this optical inductor is mounted on doorjamb 2 column 4 outward, described pre-protector is electric rotating door check mechanism (omitting among the figure), this check mechanism can adopt the check mechanism of former revolving door, described optical inductor is connected in the braking circuit of described check mechanism with the limit switch of control revolving door apart from the doorjamb distance, and this braking circuit adopts conventional brake control circuit to get final product.Described optical inductor can be grating 3, is arranged near ground location.Above-mentioned photo-protection is two, is arranged on outside the offside door frame 2 of revolving door two side entrances.Described limit switch can be optoelectronic switch or Hall element.Described limit switch can be installed in revolving door 1 or door upper ledge.
As shown in Figure 3, Figure 4, described pre-protector can be roll guard 5, this roll guard 5 is lifted on doorframe 2 outsides and by motor-driven, described roll guard 5 when the early warning switch connection and revolving door 1 move in opposite directions, and when meeting, stop and when revolving door 1 overlaps with doorjamb 2, returning original position with revolving door 1.Described roll guard 5 can be two, is arranged on outside the left frame 2 of 1 liang of side entrance of revolving door.Described roll guard 5 can be formed by connecting by flexible material, and this roll guard had both made the pedestrian knock also and can not damage.
The course of work of the utility model safety device following (referring to Fig. 2, Fig. 4):
When revolving door does not also enter setting regions (promptly also beyond distance doorjamb setpoint distance), the early warning switch is in the releasing alert status, (this moment, revolving door was nearer apart from doorjamb after revolving door enters setting regions, the folder people is easily taken place), the early warning switch is in alert status, if having the people approaching this moment, and the early warning switch connection, the action of control revolving door brake stops operating (as shown in Figure 1 and Figure 2) revolving door; Perhaps control roll guard and move to revolving door, with pedestrian retaining outdoors, thereby play the safeguard protection effect.When roll guard and revolving door intersect by being arranged on the travel switch on roll guard or the revolving door or stopping near switch control roll guard, and when revolving door rotates to doorjamb, by forming switch or controlling the roll guard correcting action near switch.If do not have object approaching at alert status, revolving door continues rotation (as shown in Figure 2) or roll guard is failure to actuate (as shown in Figure 4).
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement done based on the utility model or modification all belong to the utility model claim.
