Problems solved by technology

The existing connection method between the mechanical lock and the limit switch can easily cause signal transmission failure
Due to the frequent use of the switch of the safety door during the operation of the subway, only relying on the unlocking steel wire 100 to control the structure of the unlocking paddle 200, it is easy to cause the unlocking paddle 200 to fail to reset normally during repeated actions, and then the travel switch 300 is always on. In the triggered state, the door control unit (DCU) will stop executing other control level commands after receiving the manual unlock signal, resulting in failure to open the door normally and affecting the normal operation of the train

Embodiment 1

[0026] figure 2 It is a schematic diagram of the overall structure of Embodiment 1 of the present invention, image 3 for figure 2 side view. like figure 2 and combine image 3 As shown, the present invention provides an electronically controlled mechanical lock A, which includes a base plate 1 on which an electromagnet 2 and a clutch plate 5 capable of moving up and down are arranged. The electromagnet 2 is fixed on the base plate 1, and the mandrel of the electromagnet 2 is connected with the clutch plate 5 at the same time. The clutch plate 5 is movably arranged on the bottom plate 1 . The mandrel of the electromagnet 2 absorbs or releases the clutch plate 5 when the power is on or off. The bottom plate 1 is provided with a pair of travel switches 4, and the contact 41 of each travel switch 4 touches the clutch plate 5 in the power-off state, and is triggered by the clutch plate 5 in the power-on state. The attraction or release of the electromagnet 2 can drive th...

Embodiment 2

[0033] Figure 8 It is a schematic diagram of the overall structure of Embodiment 2 of the present invention. like Figure 8 As shown, it is another embodiment of the present invention. In this embodiment, the pair of travel switches 4 are arranged on the left and right sides of the clutch plate 5 respectively, with the contacts 41 facing down. The top of the clutch plate 5 includes two protrusions 51 separated left and right, and the tops of the protrusions 51 are in contact with the contacts 41 .

[0034] The specific action process is that when the electromagnet 2 is energized, the mandrel absorbs the clutch plate 5 and moves upward, and the two protrusions 51 on the top of the clutch plate 5 touch the contact 41 and trigger to generate corresponding signal transmission and execute related actions. When the electromagnet 2 is powered off, the adsorption force of the spindle disappears, the clutch plate 5 moves downward, and the two protrusions 51 on the top of the clutch...

Abstract

The invention relates to an electric control mechanical lock which comprises a bottom plate (1), wherein the bottom plate (1) is provided with an electromagnet (2) and a clutch plate (5); a mandrel of the electromagnet (2) can adsorb or release the clutch plate (5) under a power-on or power-off state, and the bottom plate (1) is provided with a pair of the travel switches (4); a contact point (41) of each travel switch (4) is touched with the clutch plate (5) under the power-off state, and is triggered by the clutch plate (5) under the power-on state; the clutch plate and an outer door leaf hanging piece are positioned in a holding-on manner; and the bottom plate (1) is provided with a pair of locking piece backstops (6) which are arranged corresponding to backstop blocks on the outer door leaf hanging piece.A safety gate comprises a gate machine and left and right safety gate bodies (20) arranged on the gate machine, and is provided with the electric control mechanical lock. The electric control mechanical lock provided by the invention has the advantages that the structure is simple, the stressed force is reasonable, the operation is smooth and not limited, the frequent operation requirements of the safety gate are met, a signal is translated into exact transmission, and the transmission and feedback of the signal are convenient in a hand-motion unblocking operational process.

Description

technical field [0001] The invention relates to an electronically controlled mechanical lock and a safety door with the electronically controlled mechanical lock, in particular to an electronically controlled mechanical lock for a subway safety door system and a safety door with the electrically controlled mechanical lock, belonging to machinery manufacturing and electronics field of control technology. Background technique [0002] The subway safety door system is a multi-disciplinary high-tech product involving architecture, mechatronics, and communication. It includes a comprehensive control room and safety doors installed on each subway platform. The safety door separates the platform waiting area from the train operating area. The normal opening and closing of the safety door must be converted into a signal through the travel switch and transmitted to the comprehensive control room, and the status of each safety door can be intuitively reflected through the monitoring s...
