On the basis, two ends of the movable clamping plate are respectively provided with a group of push rods and driven gears, and the driving gear is meshed between the two driven gears.
Preferably, the driving means is an electromagnet.
On the basis, a first reset detection switch which can be triggered by a movable clamping plate which is moved away from the fixed clamping plate to be reset and a second reset detection switch which can be triggered by a push rod which is moved away from the movable clamping plate to be reset are respectively arranged on the machine base.
The invention has the following beneficial effects: when the elevator moves accidentally, the driving devices such as the electromagnet and the like can trigger to move to drive the swing rod to swing, the hook lock of the movable clamping plate is released, the movable clamping plate is clamped to the fixed clamping plate under the elastic action of the spring, the elevator traction rope between the movable clamping plate and the fixed clamping plate is clamped tightly, the elevator is stopped, and the safety accident is avoided. When the rope holding device needs to be reset, the power device drives the push rod to rotate through the gear mechanism, the push rod serving as the lead screw can move axially, the movable clamp plate of the rope holding device can be pushed to move away from the movable clamp plate, the rope holding device is opened and reset, manual reset is not needed, and convenience is brought to maintenance of an elevator.

Detailed Description
As shown in fig. 1-3, an elevator rope clasping device comprises a fixed clamp plate 2 fixed on a machine base 1 and a movable clamp plate 4 connected with the fixed clamp plate 2 in a sliding manner through a guide post 3, wherein a spring 5 for keeping the movable clamp plate 4 to move towards the fixed clamp plate 2 is arranged between the movable clamp plate 4 and the machine base 1.
In the invention, a swing rod 6 which is arranged on the machine base 1 in a vertically swinging way is arranged, the swing rod 6 is provided with a hook part which can hook the movable clamping plate 4 and keep a certain distance away from the fixed clamping plate 2, and the machine base 1 is provided with a driving device which drives the swing rod 6 to release the swinging of the movable clamping plate 4. Specifically, the swing rod 6 can be mounted on the base 1 behind the movable clamping plate 4 through a transverse shaft 7, a hook plate 8 is fixed on the rear side of the movable clamping plate 4, and a hook part of the swing rod 6 can hook the hook plate 8, so that the rope holding device is kept in an open state. When the elevator moves accidentally, the hook part of the driving device is triggered to start to drive the swing rod 6 to swing away from the hook plate 8, the hook lock of the movable clamping plate 4 is released, the movable clamping plate 4 moves towards the fixed clamping plate 2 under the action of the spring 5, the traction rope penetrating between the fixed clamping plate 2 and the movable clamping plate 4 is clamped tightly, the elevator is stopped, and safety accidents are avoided. The driving device in this embodiment adopts the electromagnet 9, after the electromagnet 9 is powered on, the iron core thereof retracts to pull the swing rod 6 to swing downwards, the hook part at the other end of the swing rod 6 swings upwards to leave the hook plate 8, the hook lock of the movable clamp plate 4 is released, and the rope clamping device executes the rope clamping action.
The device is characterized in that a push rod 10 used for pushing the movable clamping plate 4 to move away from the fixed clamping plate 2 is arranged, the push rod 10 is in threaded connection with the fixed clamping plate 2, a driven gear 11 which is fixed in the circumferential direction and connected in an axial sliding mode is further mounted on the push rod 10, the driven gear 11 is meshed with a driving gear 12, and the driving gear 12 is driven to rotate by a power device. The driven gear 11 and the driving gear 12 can be mounted on the machine base 1 through a side plate, so that the driven gear 11 and the driving gear cannot move axially, the driven gear 11 is matched with the push rod 10 through a kidney-shaped hole, and the push rod 10 is in threaded fit with the fixed clamping plate 2, so that the push rod 10 can only move axially while rotating. The power unit may employ a motor to drive the rotation of the drive gear 12. When the rope holding device needs to be reset, the gear mechanism drives the push rod 10 to rotate through rotation of the control motor, so that the push rod 10 moves towards the movable clamping plate 4, the movable clamping plate 4 is pushed to move away from the movable clamping plate 2 until the hook part of the swing rod 6 hooks the hook plate 8 of the movable clamping plate 4, and the opening and resetting of the rope holding device are achieved.
In order to ensure the stability of the reset device during operation, a set of push rods 10 and driven gears 11 may be respectively disposed at two ends of the movable clamp plate 4, and the driving gear 12 is engaged between the two driven gears 11 to drive the two push rods 10 to synchronously extend and retract. Therefore, the two push rods 10 can push the left end and the right end of the movable clamping plate 4 to keep balance movement, so that the movable clamping plate 4 is synchronously pushed to open and reset to ensure the stability during action.
