DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

As shown in Fig. 1-2, an elevator rescue device in an embodiment of the utility model comprises a device body 100, and the device body 100 comprises a main frame 10, a sheave assembly 30 and a brake assembly 20. The main frame 10 comprises a pedal 11 for supporting rescuers, and the sheave assembly 20 is fixed on the main frame 10 and comprises a plurality of sheaves 31. The brake assembly 20 comprises a rope clamp 21 and a controller 22, the rope clamp 21 comprises two rope clamping wheels 211 arranged opposite to each other, the wire rope 300 is simultaneously stuck between the plurality of sheaves 31 and between the rope clamping wheels 211, the sheave 31 is used to constrain the device body 100 on the wire rope, so that the device body 100 can only move along the wire rope, and the rope clamping wheels 211 are used to provide friction force for braking and deceleration, and the controller 22 is used to control the rope clamping wheels 211 to move closer to and farther from each other to clamp or loosen the wire rope 300, thereby controlling the moving speed and the braking stop operation.

When an elevator fails, the car is trapped in a non-level area, and the car door cannot be opened, the rescuer can open any upper floor door, clamp the sheave assembly 30 and the rope clamp 21 on the wire rope in the hoistway, put down the pedal 11, and the rescuer stands on the pedal 11. The device body 100 and the rescuer move downward under the action of gravity, and the clamping force of the rope clamp 21 is controlled by operating the controller 22 to make the device body 100 slowly slide down. When it is close to the top of the car, the rope clamp wheel 211 is clamped by operating the controller 22 to clamp the wire rope 300, and the friction force increases. The device body 100 slows down and brakes until it stops, and rescues the trapped people in the car through the rescue window on the top of the car. Therefore, the rescuer can move to the elevator car to carry out rescue when the car is stranded in the non-door opening area, the floor interval is large, the car is far from the nearest upper hall door, and there is no rescue ladder in the hoistway, which improves the safety of rescue.

In this embodiment, the sheave assembly 30 includes a triangular sheave bracket 32 for fixing the sheave 31, each corner of the sheave bracket 32 is rotatably provided with a sheave 31, and the wire rope 300 passes between the three sheaves 31 and abuts against each sheave 31. The sheave assembly 30 cooperates with two rope clamping wheels 211 to fix the main frame 10 on the wire rope 300 from both ends, and the main frame 10 can only translate along the extension direction of the wire rope 300, and will not rotate or cause danger in other situations.

Furthermore, the bracket 212 is an equilateral triangle bracket, each groove wheel 31 is equidistant, and one side of the bracket 212 is parallel to the wire rope 300. Therefore, after the wire rope 300 passes between the groove wheels 31, each groove wheel 31 is in contact with the wire rope 300 and the force is basically the same. Therefore, the main bracket 10 can be better limited on the wire rope 300 to avoid the situation where the groove wheel 31 is detached from the wire rope 300.

It is easy to think that in order to further improve the limiting effect of the main frame 10, two groove wheel assemblies 30 are provided on the main frame 10, which are respectively arranged on the upper and lower sides of the rope clamp 21, and the main frame 10 is fixed to the wire rope 300 from the upper and lower ends. The rope clamp 21 is arranged between the two groove wheel assemblies 30, so it is more responsible for clamping the wire rope 300, while its limiting effect is weakened.

In this embodiment, the main frame 10 includes a fixed frame 12 in addition to the pedal 11, and the pedal 11 is pivotally arranged on the fixed frame 12. Two corresponding sheave assemblies 30 are respectively fixed at the bottom position and the position near the top of the fixed frame 12 to further increase the distance between the two, so that the main frame 10 can move more smoothly on the wire rope 300.

Furthermore, the pedal 11 is arranged at the bottom of the fixed bracket 12 and can be unfolded or stored in the fixed bracket 12. When it is unfolded, the pedal 11 and the groove wheel assembly 30 at the bottom are in a relatively parallel state. When the rescuer stands on the pedal 11, the center of gravity of the entire device body 100 is lower and the stability is higher.

Preferably, a pulley 13 is provided at the bottom of the pedal 11, which can slide on the ground in cooperation with the sheave 31 in the bottom sheave assembly 30 during movement, so as to facilitate the movement of rescue personnel.

In this embodiment, the controller 22 is fixed on the top of the main support 10. The controller 22 is a manual brake release. The pull line of the manual brake release is connected to the two rope clamping wheels 211, which is used to control the distance between the two rope clamping wheels 211. When the manual brake release is squeezed, the two rope clamping wheels 211 move closer to each other to clamp the wire rope 300, the friction force increases, and the moving speed decreases. On the contrary, when the manual brake release is released, the moving speed increases. It should be noted that the rescuer needs to control the force of squeezing the manual brake release to control the moving speed. When moving to a position close to the elevator car, the manual brake release needs to be squeezed to brake and stop the entire elevator rescue device.

Since the elevator door is at a certain distance from the wire rope 300, the elevator rescue device also includes a corridor bridge assembly 200. After the elevator door is opened, the corridor bridge assembly 200 is extended into the elevator shaft to the wire rope 300, and the rescue personnel move together with the device body 100 to the wire rope 300 to carry out rescue.

The elevator rescue device provided by the utility model is further described below in conjunction with specific usage scenarios. As shown in Figure 2, when an elevator fails, the car 500 is trapped in a non-level area, and the car door cannot be opened, the rescuer can open any door on the upper floor, first set up the bridge assembly 200, enter the shaft 400 through the bridge assembly 200, clamp the sheave assembly 30 and the rope clamp 21 on the shaft wire rope 300, put down the pedal 11, and after the rescuer stands on the pedal 11, remove the bridge assembly 200, control the clamping force of the rope clamp 21 by operating the manual release brake, and let the device body 100 slowly slide down to the top of the car, and rescue the trapped person in the car through the rescue window on the top of the car.
