Abstract
The utility model discloses a door gear is closed to lift -cabin door safety, include two hoistway doors, install the closing device of hoistway door upper end, closing device includes extension spring, installing support, the installing support sets up respectively two the hoistway door upper end, the extension spring both ends respectively with set up two the installing support of hoistway door upper end is connected. Compared with the prior art, its simple structure, the cost is reduced, through being the couple form with spring both ends setting, technology has been simplified, simple to operate, the energy can be saved in hanging the mounting hole on the installing support to the couple.
Description
Technical field
This utility model relates to lift facility field, particularly to a kind of elevator door safety door closer-holder.
Background technology
Existing hoistway door is closed door and two fan hall doors is closed by use door heavy hammer structure, and door heavy hammer structure is mainly by weight, weight set; steel wire rope, the parts such as pulley composition, it is fixed on the upside of hoistway door through screw; make hoistway door in the case of not by external force, under the action of gravity of weight, drive hall door oneself Guan Bi; play a protective role; but this door heavy hammer structure closing a mode is complicated, and parts kind is many, and cost is high; installing more complicated, maintenance work amount is big.
Utility model content
This utility model provides a kind of elevator door safety door closer-holder, it is therefore intended that provide a kind of simple in construction, easy for installation, the safe door closer-holder of reduction cost.
This utility model provides a kind of elevator door safety door closer-holder, including two fan hoistway doors, the closing device that is arranged on described hoistway door upper end, described closing device includes stretching spring, mounting bracket, described mounting bracket is separately positioned on two fans described hoistway door upper end, and described stretching both ends of the spring is connected with the mounting bracket being arranged on two fans described hoistway door upper end respectively.
Further, described mounting bracket is mounted by means of bolts on described hoistway door upper end.
Further, described stretching both ends of the spring is hook-shaped, and described mounting bracket is provided with the installing hole that can place hook, and described stretching both ends of the spring is connected with described mounting bracket in hanging over described installing hole.
This utility model has the beneficial effect that: use this novel door closer-holder, by being respectively provided with mounting bracket in the upper end of two fan hoistway doors, two mounting brackets are provided with stretching spring, when under the induced effect at enabling motor, when opening hoistway door, stretching spring is in extended state；When hoistway door need to close, enabling motor quits work, two fan hoistway door move toward one another under the pulling force effect of stretching spring, closes hoistway door, its simple in construction, reduces cost；By both ends of the spring is arranged in hook-shaped, hang in the installing hole in mounting bracket, simplify technique, easy for installation, save the energy.
Accompanying drawing explanation
Fig. 1 is hoistway door door closer-holder structural representation in prior art；
Fig. 2 is this utility model one elevator door safety door closer-holder structural representation；
In figure, 1-weight, 2-pulley, 3-steel wire rope, 4-mounting bracket, 5-stretches spring.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model embodiment is described in further detail.
This utility model provides a kind of elevator door safety door closer-holder, such as Fig. 1, shown in Fig. 2, including two fan hoistway doors, it is arranged on the closing device of described hoistway door upper end, described closing device includes stretching spring 5, mounting bracket 4, described mounting bracket 4 is separately positioned on two fans described hoistway door upper end, the two ends of described stretching spring 5 are connected with the mounting bracket 4 being arranged on two fans described hoistway door upper end respectively, in the present embodiment, preferably, the two ends of described stretching spring 5 are hook-shaped, described mounting bracket 4 is provided with the installing hole that can place hook, the hook at described stretching spring 5 two ends is connected with described mounting bracket 4 in hanging over described installing hole, described mounting bracket 4 is mounted by means of bolts on described hoistway door upper end.
Operation principle of the present utility model is as follows:
During enabling, under the induced effect of enabling motor, opening hoistway door, stretching spring is in extended state；During hoistway door Guan Bi, enabling motor quits work, two fan hoistway door move toward one another under the pulling force effect of stretching spring, closes hoistway door.
Obviously, those skilled in the art can carry out various change and modification without deviating from spirit and scope of the present utility model to this utility model.So, if these amendments of the present utility model and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also intended to comprise these change and modification.
