[0001] The utility model relates to a heat-insulating door, in particular to a lifting heat-insulating door. Background Art
[0002] The previous lifting heat-insulating door was driven by a motor and was not equipped with a limit switch. The operator controlled the lifting position according to experience, and automatic control could not be achieved. In addition, when the lifting was not in place, the heat-insulating effect was weakened. At the same time, there was no transparent viewing window on the heat-insulating door, so the situation inside the door could not be observed at any time. When the door did not need to be lifted, the power could not be cut off, and it could not prevent personnel from misoperating the lifting door, resulting in potential safety hazards.

A rope take-up device is provided above the lifting lug. A connecting rope is provided between the lifting lug and the rope take-up device. One end of the rope take-up device is connected to one end of a rotating shaft, and the other end of the rotating shaft is connected to a reduction motor. An upper limit switch is provided at the upper part of the left guide groove and the right guide groove, and a lower limit switch is provided at the lower part. A self-locking switch is provided below the lower limit switch. The self-locking switch is connected to a self-locking pin. A heat-insulating pad is provided inside the protective heat-insulating door, and a viewing window is provided on the protective heat-insulating door.
[0005] Further, two lifting lugs are provided at the top of the protective heat-insulating door. A rope take-up device is provided above each lifting lug. Each rope take-up device is connected to the rotating shaft, and the two rotating shafts are connected to the reduction motor.
[0006] Further, an automatic controller is provided on one side of the protective heat-insulating door.
[0007] Further, the self-locking pin is connected to the protective heat-insulating door in a matching manner.
[0008] Further, when the protective heat-insulating door does not need to be lifted, the self-locking pin is inserted into the protective heat-insulating door, and the self-locking switch acts to cut off the power supply.
[0009] Beneficial effects: Compared with the prior art, the remarkable advantages of the present utility model are as follows: The overall structure of the present utility model is reasonably arranged, and it mainly consists of the following components: a reduction motor, a rotating shaft, a rope winder, a guiding groove, an upper limit switch, a lower limit switch, a self-locking pin, a self-locking switch, a protective heat-insulating door, a viewing window, a heat-insulating pad, and an automatic controller; the reduction motor drives the rotating shaft and the rope winder to act, so that the protective heat-insulating door moves up and down in the guiding groove, and the up and down positions are controlled by the upper limit switch and the lower limit switch. The protective heat-insulating door includes a transparent viewing window and a heat-insulating pad. After the door is closed, it can play a role in heat preservation and insulation inside and outside the door. At the same time, the situation inside the door can be observed at any time outside the door. When the door does not need to be lifted or lowered, the self-locking pin can be locked. At this time, the self-locking switch acts to cut off the power supply, thereby preventing personnel from misoperating the lifting door and playing a role in safety protection. The equipped PLC automatic controller can automatically control the entire action process. Description of the Drawings
