The utility model adopts the technical scheme as follows:

the utility model provides a braking rope clamping system for when elevator meets accident, including towing the system, be equipped with the rope clamping system in the well, the rope clamping system includes monitoring devices, the PLC switch board, the rope clamp, monitoring devices includes 4 infra red ray induction points, a plurality of speed detector, wherein infra red ray induction point installs respectively at the driving sheave, the car wheel, in the recess of counterpoise wheel, speed detector installs on the well wall through the support frame that is equipped with, wire rope passes from speed detector, the wire rope position in driving sheave one side is installed to the rope clamp, the PLC switch board is installed on the well, and the braking of electricity connection monitoring devices control rope clamp.

Furthermore, the rope clamping device comprises a rack plate and a rack, wherein a driving motor is arranged on the rack plate, the rack plate is connected with the rack, and the driving motor enables the steel wire rope to be clamped by the rack.

Further, the rope clamping device further comprises a spring plate and a spring, the driving motor is installed on the spring plate, and the spring is connected between the spring plate and the rack plate. The spring has elasticity, and it is limited compressed, makes the wire rope not damaged when both sides rack compresses to the limit.

Further, the racks are connected side by a plurality of U-shaped or V-shaped grooves.

Further, there are 6 speed detectors, distributed as follows: one is located the another side that drags the wheel department and is relative to the rope clamping device, and the both sides of counterpoise wheel respectively have one, have one between two car wheels, and the upside of two car wheels respectively has one.

The utility model discloses following beneficial effect has: whether the steel wire rope is separated from the groove of the guide wheel or not is monitored, the motion condition of the steel wire rope at each position is monitored, and when an abnormal condition is found, the rope clamp acts rapidly, so that the elevator stops working immediately.

Drawings

FIG. 2 is a schematic view of the rope clamp;

figure 3 is a schematic view of an optimized rope clamp.

In the figure, 1 is a counterweight wheel, 2 is a spring plate, 3 is a spring, 4 is a PLC control cabinet, 5 is a traction sheave, 6 is an infrared sensing point, 7 is a floor, 8 is a steel wire rope, 9 is a speed detector, 10 is a car wheel, 11 is a rack, 12 is a rack plate, 13 is a hoistway, and 14 is a driving motor.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example 1: as shown in fig. 1, 2, and 3, a braking rope clamping system for an elevator in an accident, including a traction system, a rope clamping system is provided in a hoistway 13, the rope clamping system includes a monitoring device, a PLC control cabinet 4, and a rope clamp, the monitoring device includes 4 infrared sensing points 6 and a plurality of speed detectors 9, wherein the infrared sensing points 6 are respectively installed in a groove of a traction sheave 5, a car sheave 10, and a counterweight sheave 1, the speed detectors 9 are installed on a wall of the hoistway 13 through a supporting frame provided, a steel wire rope 8 passes through the speed detectors 9, the rope clamp is installed at a steel wire rope position on one side of the traction sheave 5, the PLC control cabinet 4 is installed on the hoistway 13, and the monitoring device is electrically connected to control the rope clamp to brake.

The elevator is in friction transmission through a steel wire rope 8, the steel wire rope 8 bypasses a traction sheave 5, two ends of the traction sheave 5 are respectively connected with a car wheel 10 and a counterweight wheel 1, and the car is driven to lift by a motor.
