Description

Technical Field

[0001] The utility model relates to a lifting door, in particular to an electric lifting door. Background Art

[0002] Electric lifting doors are widely used in industrial factories. Generally, an operator manually operates a control box, which sends corresponding instructions to a motor, and the motor drives the door panel to lift and lower, thereby realizing opening and closing. At present, the following problems exist: 1) Some workers leave work before the door panel is completely closed, which may bring the risk of theft to the equipment and property in the factory; 2) Some workers leave work early without closing the door panel, and the electric lifting door is completely open, which not only has the risk of theft, but also may cause safety risks such as fires in case of strong winds, heavy rains, etc. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electric lifting door that can avoid the situation of incomplete closing and can remind the duty personnel to close the door in time.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An electric lifting door includes a motor for driving the door panel to lift and lower and its control box. A limit block is provided at the bottom end of the door panel, and an upper travel switch, a lower travel switch and an alarm that can set the working time are provided near the door panel; the upper travel switch and the lower travel switch are respectively electrically connected to the control box. When the bottom end of the door panel rises to the fully open position, the limit block presses up the upper travel switch to trigger the motor to stop. When the bottom end of the door panel descends to the fully closed position, the limit block presses down the lower travel switch to trigger the motor to stop; the lower travel switch is electrically connected to the alarm.

[0006] Further, the motor is equipped with a backup battery.

[0007] Further, an indicator light for displaying the remaining energy status is provided on the backup battery.

[0008] Further, the alarm adopts an audible and visual alarm.

[0009] Further, the motor drives the door panel to lift and lower through a rotating shaft and a winding drum. The rotating shaft is rotatably installed at the upper end of the door frame through a bearing seat, and the winding drum is installed on the rotating shaft and can wind and unwind the door panel.

[0010] Further, the operation area of the control box is arranged in a protective cover, and the protective cover is opened by fingerprint or key.

[0011] Further, both sides of the door panel are located in the guide grooves on both sides of the door frame.

[0012] The beneficial effects of the utility model are as follows:

[0013] The newly added limit block, upper travel switch and lower travel switch enable the door panel to stop automatically when it rises to the in-place position and when it descends to the in-place position, avoiding the situation of incomplete closing; the newly added limit block, lower travel switch and alarm make the alarm sound if the lower travel switch is not pressed after work when the working time of the alarm is set during off-duty hours, thus reminding the on-duty personnel in the factory to close the door in time and avoiding potential hazards.

[0018] The present invention will be further described below with reference to the drawings and embodiments.

[0019] Embodiment 1

[0020] This embodiment discloses an electric lifting door, as Figure 1 and Figure 2 shown, including a door frame 1, a door panel 4, a motor 7 for driving the lifting of the door panel 4 and its control box 10, a limit block 12, an upper travel switch 6, a lower travel switch 13 and an alarm 11; among them, the limit block 12, the upper travel switch 6, the lower travel switch 13 and the alarm 11 are newly added devices, and: the limit block 12 is arranged at the bottom end of the door panel 4, see Figure 1 and Figure 2 ; the upper travel switch 6 is arranged near the door panel 4, and the upper travel switch 6 is electrically connected to the control box 10, see Figure 1 and Figure 2 , when the bottom end of the door panel 4 rises to the fully opened position, the limit block 12 presses against the upper travel switch 6 to trigger the motor 7 to stop, see Figure 2 ; the lower travel switch 13 is arranged near the door panel 4, and the lower travel switch 13 is electrically connected to the control box 10, see Figure 1 and Figure 2 , when the bottom end of the door panel 4 descends to the fully closed position, the limit block 12 presses down the lower travel switch 13 to trigger the motor 7 to stop, see Figure 1; The alarm 11 can set the working time, and the lower travel switch 13 is electrically connected to the alarm 11.

[0021] According to the above solution: The newly added limit block 12, upper travel switch 6 and lower travel switch 13 enable the door panel 4 to stop automatically when it rises in place and when it descends in place, avoiding the situation of not closing in place; The newly added limit block 12, lower travel switch 13 and alarm 11 enable the alarm 11 to alarm if the lower travel switch 13 is not pressed after work when the working time of the alarm 11 is set during off-duty hours (e.g., 17:30~08:30), thus reminding the on-duty personnel in the factory to close the door in time and avoiding potential hazards.
