Description

Technical Field

[0001] The utility model relates to the technical field of elevator protection, in particular to an elevator traction rope break protection device. Background Art

[0002] In recent years, the elevator industry has developed rapidly, and the number of elevator applications has continued to increase. Due to the continuous occurrence of safety accidents caused by elevator failures, which have caused great damage to people's lives and property, the safety performance requirements of elevators have continued to increase. Elevators, especially traction elevators, mainly rely on the tension of multiple traction ropes to perform vertical ups and downs in the air. Once the traction rope breaks, it may cause serious consequences such as casualties and equipment damage. When the traction rope of a traction elevator is disconnected or the traction rope is loose due to abnormal elongation, etc., it can effectively prevent the elevator from operating in such conditions, which is directly related to the performance of the elevator and the safety of passengers' lives and property.

[0003] In the process of vertical lifting, the traction rope of the current traction elevator will be worn out after long-term operation. In some cases, the traction rope will be worn out or even broken, causing the car to fall and casualties. The safety and stability of the elevator cannot be guaranteed. Utility Model Content

[0006] Preferably, one end of the movable rod is fixedly connected to the counterweight block, an elastic member is connected to the bottom of one end of the movable rod, and one end of the elastic member is fixedly connected to the support frame.

[0007] Preferably, the first movable plate and the second movable plate are respectively inserted into two sides of the support frame.

[0008] Preferably, the sensor is connected to an alarm via a line.

[0009] Preferably, the motor is a servo electric cylinder.

[0010] Preferably, the elastic member is a return spring.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] First, the utility model can quickly stop the operation of the elevator by setting a movable rod and a motor. The rope breaks, causing one end of the movable rod to lose traction, and the other end of the movable rod moves upward. The transmission rod is tilted and separated from the sensor. The sensor sends a signal to the motor, and the motor pushes the first movable plate and the second movable plate to move outward. The guide rail limits the elevator lifting to avoid safety accidents.

[0013] Second, the utility model can increase the descending speed of one end of the movable plate by arranging a counterweight block and an elastic member. The counterweight block at one end of the movable rod accelerates the descending speed of one end of the movable rod through its own weight. At the same time, the elastic member pulls the movable rod downward, thereby increasing the descending speed of one end of the movable rod, thereby increasing the reaction speed of the device, pushing the first movable plate 7 and the second movable plate outward in time, and improving the safety of the device.

When the rope 3 breaks, one end of the movable rod 5 loses traction and moves downward, causing the other end of the movable rod 5 to move upward, and the transmission rod 9 is tilted by the upward movement of one end of the movable rod 5, causing the transmission rod 9 to separate from the sensor 12. At this time, the sensor 12 sends a signal to the motor 6, and the motor 6 simultaneously pushes the first movable plate 7 and the second movable plate 8 to move outward through the output shaft, and the first movable plate 7 and the second movable plate 8 abut against the guide rail to limit the lifting and lowering of the elevator, thereby avoiding a greater safety accident.

[0024] The motor 6 adopts a servo electric cylinder, which has various properties close to those of a hydraulic cylinder, such as a thrust of up to 35 tons, a speed of up to 2 m / s, and a relatively long stroke, thereby improving the safety of the device.

[0025] The elastic member 11 is a return spring, and one end of the movable rod 5 is pulled downward by the return spring.

[0026] When in use, when the rope 3 breaks, one end of the movable rod 5 loses traction and moves downward, causing the other end of the movable rod 5 to move upward, and the transmission rod 9 is tilted by the upward movement of one end of the movable rod 5, causing the transmission rod 9 to separate from the sensor 12. At this time, the sensor 12 sends a signal to the motor 6, and the motor 6 simultaneously pushes the first movable plate 7 and the second movable plate 8 to move outward through the output shaft, and the first movable plate 7 and the second movable plate 8 are abutted against the guide rail to limit the lifting and lowering of the elevator to avoid a larger safety accident. The sensor 12 also sends a signal to the alarm 13, and an alarm signal is sent to the outside world through the alarm 13 to facilitate rescue personnel or maintenance personnel to arrive in time. At the same time, the counterweight block 10 at one end of the movable rod 5 accelerates the descending speed of one end of the movable rod 5 through its own weight, and the elastic member 11 pulls the movable rod 5 downward, thereby increasing the descending speed of one end of the movable rod 5, thereby improving the reaction speed of the device, and timely pushing the first movable plate 7 and the second movable plate 8 outward to improve the safety of the device.
