Problems solved by technology
At this time, if the elevator wants to return to the normal working state, it is necessary to reset the rope grip. The traditional reset method has a complex structure and requires a large operating space. According to the structure design of the rope grip, the generalization is low and can only Manual operation will undoubtedly bring a lot of inconvenience to the elevator reset and maintenance

Embodiment Construction
[0008] Such as figure 1 As shown, a reset device for an elevator rope grip includes a push rod 1, a fixed seat 2, a driven gear 3 and a driving gear 4 meshing with the driven gear 3, and the fixed seat 2 is fixed on the frame of the rope grip On the top, there is a threaded hole in the fixed seat 2, and the push rod 1 is threadedly fitted in the threaded hole, the driven gear 3 is axially slid and circumferentially fixedly installed on the push rod 1, and the driving gear 4 is driven by the power device its turning.
[0009] Elevator rope grip generally is made of moving splint and fixed splint, can use fixed splint as fixed seat 2 like this, push rod 1 is opposite moving splint, power devices such as gear mechanism and motor are installed on the support of rope gripping device. The motor drives the driving gear 4 to rotate, the driving gear 4 drives the driven gear 3 to rotate, and the driven gear 3 drives the push rod 1 to rotate. Because the push rod 1 is threadedly matche...

The invention discloses a resetting device of an elevator rope holding device. The resetting device comprises push rods, fixed bases, driven gears and a driving gear engaged with the driven gears. The fixed bases are fixed on a pedestal of the rope holding device. Threaded holes are formed in the fixed bases. The push rods are arranged in the threaded holes in a thread fit and penetrating mode. The driven gears are installed on the push rods and can slide in the axial direction and be fixed in the circumferential direction. The driving gear is driven by a power device to rotate. According to the resetting device of the elevator rope holding device, the push rods and the fixed bases constitute movable lead screw mechanisms, the power device drives the push rods to rotate through gear mechanisms, the push rods serving as lead screws move in the axial direction, thus, a movable clamping plate of the rope holding device is pushed to get away, and the rope holding device can be opened and reset. Thus, by the adoption of the resetting device, automatic resetting of the rope holding device can be achieved by controlling the power device such as a motor without manual resetting, and convenience is brought to resetting and maintaining of an elevator.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a reset device in an elevator rope grip. Background technique [0002] The elevator rope grip reset device is mainly used in the elevator rope grip. The rope grip is used as a safety component of the elevator. When the elevator opens the car door in the door opening area, the sudden movement of the elevator is detected by the electrical or mechanical detection device. The rope grabber will immediately act to clamp the elevator wire rope, thereby stopping the elevator and playing a role of safety protection. At this time, if the elevator wants to return to the normal working state, it is necessary to reset the rope grip. The traditional reset method has a complex structure and requires a large operating space. According to the structure design of the rope grip, the generalization is low and can only Manual operation will undoubtedly bring a lot of inconvenience to elevator rese...
