[0003] The current construction lift automatic fence door opening and closing mode is usually electric feeding door mechanical linkage fence door, but this mode in daily use, mechanical linkage failure becomes the mainstream reason of construction lift door failure. INNOVATION CONTENT

[0004] In order to improve the reliability and safety of fence door, the application provides a lift fence door electric control device and lift.

[0005] The utility model solves the technical scheme that the above problem adopts:

[0006] The lift fence door electric control device includes the main electric control box for controlling the opening and closing of the feeding door, still includes the door opening and closing signal processing box, remote controller and fence door motor box, and the main electric control box is sequentially electrically connected with the door opening and closing signal processing box, remote controller and fence door motor box, when the door opening and closing signal processing box detects that the main electric control box controls the feeding door to open / close, the fence door motor box is controlled through the remote controller control fence door to open / close.

[0007] Further, the door opening and closing signal processing box includes power supply, first relay and second relay, when detecting that the main electric control box controls the feeding door to open, the first relay is electrified, triggers the remote controller control fence door motor box control fence door to open, when detecting that the main electric control box controls the feeding door to close, the second relay is electrified, triggers the remote controller control fence door motor box control fence door to close.

[0008] Further, it further includes anti-pinch limit switch, and the anti-pinch limit switch is fixed in the inside of the lower edge of the fence door and is connected with the fence door motor box.

[0009] Further, it further includes door opening and closing limit switch, and the door opening and closing limit switch is connected with the fence door motor box.

[0010] The lift adopts the lift fence door electric control device to control the fence door.

[0011] Compared with the prior art, the utility model has the beneficial effects that the opening and closing of the construction elevator fence door is controlled by electricity, instead of controlling the feeding door by electricity and then mechanically connecting the fence door, mechanical linkage failure is avoided, and the reliability and overall safety of the construction elevator fence door are improved. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 The utility model discloses a circuit diagram of elevator fence door electric control device. DETAILED DESCRIPTION

[0013] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is with example, and this utility model is further detailedly explained.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0014] The elevator fence door electric control device, including the main electric control box for controlling the feeding door opening and closing, still include the switch door signal processing box, the remote controller and the fence door motor box, the main electric control box is electrically connected with the switch door signal processing box, the remote controller and the fence door motor box in proper order, when the switch door signal processing box detects that the main electric control box controls the feeding door to open / close, through the remote controller control fence door motor box control fence door open / close.

[0015] As Figure 1 The switch door signal processing box MKX includes the power supply POW, the first relay O and the second relay C, when detecting that the main electric control box MCU controls the feeding door to open, the first relay O gets electricity, triggers the remote controller YKQ to control the fence door motor box M13 to control the fence door to open, when detecting that the main electric control box MCU controls the feeding door to close, the second relay C gets electricity, triggers the remote controller YKQ to control the fence door motor box M13 to control the fence door to close.

[0016] Further, it further includes anti-pinch limit switch and switch door limit switch, and the anti-pinch limit switch and the switch door limit switch are connected with the fence door motor box. The switch door limit is an ordinary travel switch, and the fence door runs to the position and triggers the corresponding switch door limit action by mechanical mode, and then stops running, and specifically includes fence door open limit SQC1a and fence door close limit SQC1. The anti-pinch limit switch is a micro switch, which is fixed inside the lower edge of the fence door. After a person or object triggers, the fence door immediately reverses and opens to the open door limit. The embodiment is provided with two anti-pinch limit switches, specifically including fence door anti-pinch limit 1 SQ14 and fence door anti-pinch limit 2 SQ15.

[0017] The embodiment also provides an elevator, which adopts the above-mentioned elevator fence door electric control device to control the fence door.

[0018] The application replaces the mechanical linkage part between the electric feeding door and the fence door by electric control, reduces the mechanical failure rate, ensures the safety of people and goods, and improves the reliability and overall safety of the construction elevator fence door.
