Description
Technical Field
The utility model relates to an electric control resetting device for emergency unlocking in a track traffic door system, which belongs to the field of track traffic door system control.
Background
Each door system on rail transit vehicles is basically provided with an internal emergency device, namely, when the vehicle breaks down or an emergency situation is met and passengers need to get off, the passengers can manually operate the devices to open the doors in the vehicle body, and the operating handles are always kept in the activated positions until the crews reset. The system can effectively ensure the safety of passengers.
The implementation mode of the reset function of the current common internal emergency unlocking is as follows:
step 1: the emergency unlocking device is activated after being operated (the unlocking handle is rotated to be opened), and the unlocking handle is always kept at an activated position through the clamping latch rod after being activated;
step 2: a crewmember key is needed to be used, a reset shaft is inserted into a key hole below the unlocking handle and rotated, and the clamping latch rod is released, so that the unlocking handle is reset (the handle is rebounded to an initial position by a torsion spring);
step 3: the unlocking handle is manually reset to the initial state.
The structure and the steps have the defects: after the emergency unlocking device is activated each time, a crewmember needs to move to the position of the equipment, and the emergency unlocking device is reset manually by a key, so that the efficiency is low, and the vehicle operation is delayed.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides an electric control resetting device for emergency unlocking in a rail transit door system, which can realize automatic resetting of emergency unlocking in a rail transit door.
The technical scheme for achieving the purpose is as follows: an electric control resetting device for emergency unlocking in a rail transit door system comprises a handle operation panel, wherein an unlocking handle is arranged on the front surface of the handle operation panel, and the electric control resetting device further comprises an electric control resetting electromagnet and a special latch rod;
the electric control reset electromagnet is arranged on the back of the handle operation panel and comprises an ejector rod driven by the electromagnet to stretch, a special latch rod is connected with the end part of the ejector rod and driven by the ejector rod, the special latch rod is connected with a reset torsion spring through a reset shaft in a pivot way, and the reset torsion spring is connected with the unlocking handle through an embedded block;
when the electromagnet drives the ejector rod to push outwards, the special latch rod is driven to rotate, and the special latch rod drives the reset torsion spring to rotate so as to reset the unlocking handle.
Further, an electric control reset electromagnet mounting bracket is arranged on the back of the handle operation panel, and the electric control reset electromagnet is fixed on the electric control reset electromagnet mounting bracket through a fastener.
Further, the electric control reset electromagnet is in signal connection with a control background of the rail transit door system.
The electric control resetting device for emergency unlocking in the rail transit door system has the following advantages:
1. the train operation efficiency is improved: after the emergency unlocking device is activated, the unlocking device can be reset remotely through the electric control device, so that the time required by operation is reduced, the time of train shutdown is reduced, and the running smoothness of the train is effectively ensured.
2. The maintenance efficiency of the train is improved: after the emergency unlocking device routine inspection is carried out, the emergency unlocking device can be reset in batches through centralized control, so that the train maintenance time is shortened, and the efficiency is improved.

FIG. 1 is a schematic diagram of a structure of an electrically controlled reset device for emergency unlocking in a rail transit door system in an unexcited state;
fig. 2 is a schematic structural view of an emergency unlocking electric control resetting device in a rail transit door system in an excited state;
fig. 3 is a side cross-sectional view of an electronically controlled reset device for emergency unlocking in a rail transit door system of the present utility model.
Detailed Description
In order to better understand the technical solution of the present utility model, the following detailed description is given by way of specific examples:
referring to fig. 1 to 3, an electronic control resetting device for emergency unlocking in a rail transit door system of the present utility model includes a handle operation panel 1, and an unlocking handle 2 is disposed on the front surface of the handle operation panel. The back of the handle operation panel is provided with an electric control reset electromagnet mounting bracket, and the electric control reset electromagnet is fixed on the electric control reset electromagnet mounting bracket through a fastener. The electric control reset electromagnet 3 comprises an ejector rod 31 which is driven by the electromagnet to stretch and retract, the end part of the special latch rod 4 is connected with the ejector rod and driven by the ejector rod, the special latch rod 4 is in pivot connection with a reset torsion spring 6 through a reset shaft 5, and the reset torsion spring 6 is connected with an unlocking handle through an embedded block 7.
The electric control reset electromagnet is in signal connection with a control background of the rail transit door system. When the emergency unlocking device is used, after the crewmember detects that a certain emergency unlocking device is activated through the central control screen of the cab, the crewmember can activate the electromagnet device behind the emergency unlocking device through control operation, so that the electromagnet ejector rod stretches out, and drives the special latch rod to release and then reset the unlocking handle. When the electromagnet drives the ejector rod to push outwards, the special latch rod is driven to rotate, the special latch rod drives the reset torsion spring to rotate, and the unlocking handle is reset to an initial state under the action of the reset torsion spring.
Besides the electromagnet, the electric control reset function can be realized through a motor, a cylinder and other devices.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
