Abstract
The utility model provides an electric overhead door comprising a door panel, a door frame which is arranged on the periphery of the door panel, a lifting device which is connected on the door panel and is used for controlling the door panel to be lifted; and the electric overhead door also comprises a protection rod, and the protection rod is hinged on the door frame. The utility model has the design of preventing the overhead door from falling off accidentally, and greatly reduces the risk that the overhead door falls off accidentally and causes personal casualties or item damage.
Description
Technical field
The utility model relates to a kind of electric up-down door, and particularly a kind of have an electric up-down door that prevents overhead door accidental device.
Background technology
The gate of factory floor is generally turnover large cargo, vehicle or device and designs hugely, previous when using mechanical type to pull, just need number people co-operate to open or close the gate, or just need increase mechanical realization such as hydraulic pressure, caused the waste of manpower or financial resources the gate.At present, the gate, workshop in the factory replaces with the electric up-down door by the original door that pulls substantially, and such replacement makes that open operation aspect, gate is quick, improved logistic efficiency.But in use some can occur as abnormal accidents such as stopping means inefficacy, wire rope dropouts accidentally, cause door-plate to come off suddenly, cause casualties or the article damage.
Therefore how providing a kind of has the electric up-down door that prevents overhead door accidental device and has become present technique field urgent problem.
The utility model content
At the technical problem of above-mentioned proposition, the purpose of this utility model is to provide a kind of electric up-down door.This electric up-down door has the design that prevents the overhead door accidental, greatly reduces the risk that overhead door causes casualties because of accidental or article damage.
For achieving the above object, the utility model provides a kind of electric up-down door, comprising:
Door-plate;
Doorframe is arranged at described door periphery;
Lifting gear is connected in described door-plate, in order to control described door-plate lifting;
This electric up-down door also comprises fender rod, and described fender rod is articulated on the described doorframe.
According to design of the present utility model; this electric up-down door also comprises protection switch; this protection switch is electrically connected with described lifting gear; when described fender rod is positioned on the described door-plate lift path; described fender rod disconnects this protection switch, makes described lifting gear outage, when this fender rod breaks away from described door-plate lift path; described fender rod makes described lifting gear energising with this protection switch closure.
According to design of the present utility model, described fender rod is two, and symmetry is articulated in the left and right sides of described doorframe, and each fender rod all is combined with protection switch separately, and described protection switch is connected mutually.
According to design of the present utility model, being provided with highly to being 1.8 meters of described fender rod apart from ground.
According to design of the present utility model, described lifting gear comprises controller, control circuit and driving-belt.
According to design of the present utility model, described driving-belt is wire rope or metallic bond.
The beneficial effect of electric up-down door of the present utility model is: increased the design of fender rod, when door-plate promoted the back as situations such as spacing inefficacy of generation or wire rope dropouts, fender rod can stop that door-plate falls.But also increased the design of protection switch, and by the interlock between fender rod and the protection switch, make to detach when not recurring protective action when fender rod that protection switch disconnects, thereby makes whole lifting gear outage, having avoided the people is the generation of maloperation situation.Therefore, this electric up-down door has improved the safety that overhead door uses greatly.In addition, it is low that this electric up-down door also has a cost, simple installation, simple to operate and advantage such as occupy little space.

The specific embodiment
For ease of better understanding the utility model, now in conjunction with the accompanying drawings a preferred embodiment of the present utility model is described in detail as follows:
Please refer to Fig. 1, Fig. 1 is the electric up-down door schematic diagram of embodiment 1 of the present utility model.As shown in Figure 1, electric up-down door of the present utility model includes door-plate 1, doorframe 2, lifting gear (not shown) and fender rod 3.Doorframe 2 is arranged at the periphery of door-plate 1, and lifting gear is connected in door-plate 1, in order to 1 lifting of control door-plate.Fender rod 3 is articulated on the doorframe 2.After lifting gear promoted door-plate 1, fender rod 3 was positioned on door-plate 1 lift path like this, and when situations such as spacing inefficacy of generation or wire rope dropout, fender rod 3 can stop the whereabouts of door-plate 1, plays the effect of protection.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is electric up-down door schematic diagram under the protection switch off-state of embodiment 2 of the present utility model, and Fig. 3 is a schematic diagram under the protection switch closure state.The electric up-down door is provided with basic identical among electric up-down door in the present embodiment and the embodiment 1; difference is that the electric up-down door also comprises protection switch 4 among this embodiment; protection switch 4 is electrically connected with the lifting gear (not shown), and links with fender rod 3, in order to power to lifting gear.As shown in Figure 2, after lifting gear promoted door-plate 1, fender rod 3 was positioned on door-plate 1 lift path, plays the effect that prevents that door-plate 1 from falling.At this moment, fender rod 3 does not act on protection switch 4, and protection switch 4 is in off-state, so lifting gear is in off-position, can't do any operation to door-plate 1.So just avoid the people for the situation that maloperation causes door-plate to fall takes place, also fender rod 3 has been had the certain protection effect simultaneously.As shown in Figure 3, when fender rod 3 conflict protection switches 4, make protection switch 4 be in closure state, and then the state that lifting gear is in have electricity to work.Just can adjust the height and position of door-plate 1 this moment by lifting gear.
Fender rod 3 in the present embodiment is two with the quantity of protection switch 4, and symmetry is articulated in the left and right sides of doorframe 2, but the utility model is not limited to this.
Lifting gear in this enforcement can comprise controller, control circuit and driving-belt, and wherein driving-belt can be wire rope or metallic bond.
According to staff's height situation, fender rod 3 can be set at apart from the bottom surface and exceed the high place of a people, and in the present embodiment, fender rod 3 is set at the height apart from 1.8 meters of bottom surfaces, but the utility model is not limited to this.
Above-described; it only is preferred embodiment of the present utility model; be not in order to limit scope of the present utility model; be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
