Problems solved by technology

For example, the floor space of shopping malls is relatively large, which may reach about 4-5 meters, and the car may not reach the leveling position, so self-rescue cannot be realized
[0005] 2. The moving direction of the car can only be upward. When the car rushes to the top, it cannot move down to the leveling position. In this case, self-rescue cannot be realized.
[0006] 3. The required operating force is large
[0007] 4. The operation is complicated, and many bolts need to be removed, which increases the difficulty of operation
[0008] 5. The handle position of the self-rescue device is high, and adults or children with short heights cannot use it
[0009] In summary, the existing elevator self-rescue devices and methods still need to be improved

Embodiment 1

[0055] Such as Figure 1-Figure 10 As shown, the self-rescue device in the car includes a rescue box 5 and an operating mechanism located on the side wall of the car 4 .

[0056] Wherein, the operating mechanism includes a rescue rope 2, a driving wheel assembly supported in the rescue box 5 and matched with the rescue rope 2, and an operating handle 14 connected with the driving wheel assembly. The self-rescue device is additionally provided with a fixed pulley 7 used to be fixed at the bottom of the hoistway where the car 4 is located. One end of the rescue rope 2 is fixed on the top of the hoistway where the car 4 is located by using a fixed rope end 1, and the other end bypasses the fixed pulley downwards. Pulley 7, then ascends through rescue box 5 and is connected with a movable rope head 9 that hoistway top is provided with, see figure 1 .

[0057] In this embodiment, the number of the drive wheel assemblies is two, which are respectively the left drive wheel assembly...

Embodiment 2

[0072] Such as Figure 11-Figure 13 As shown, in this embodiment, in the self-rescue device in the car, the rescue rope 2 is tangent to the driving wheels 602, 802 of the left and right driving wheel assemblies 6, 8, and the rescue box 5 corresponds to the left and right driving wheels Components 6 and 8 are provided with a block 28 to prevent the rescue rope 2 from breaking away from the drive wheel. The end of the movable rope head 9 is provided with a connecting block II22, the top of the shaft is provided with a grooved rope head base II23, and the bottom surface of the grooved rope head base II23 is provided with a through hole for the movable rope head 9 to pass through. A reset spring II 24 is provided between the bottom surface of the base II 23 of the rope head and the connection block II 22, the reset spring II 24 is set on the movable rope end 9, and the top surface of the connection block II 22 is connected with the gate line 10, and the gate line 10 is divided int...

Embodiment 3

[0075] Such as Figure 14 , Figure 15 As shown, in the self-rescue device in the car, the rescue box 5 is respectively provided with left and right tensioning pulley sets 29, 30 to prevent the rescue rope 2 from slipping at the positions corresponding to the left and right drive wheel assemblies 6, 8, and the fixed pulley 7 The rescue rope 2 on the left side is clamped between the tensioner wheel of the left tensioner wheel set 29 and the driving wheel of the left drive wheel assembly 6, and the rescue rope 2 on the right side of the fixed pulley 7 is clamped by the right tensioner wheel set 30. Between the tensioner wheel and the driving wheel of the right driving wheel assembly 8. Left and right tensioning wheel group 29,30 are made up of two tensioning wheels respectively, to increase the traction of driving wheel.

[0076] The end of the movable rope head 9 is provided with a connecting block II22, the top of the shaft is provided with a grooved rope head base II23, and...

Abstract

The invention relates to the technical field of elevator rescue equipment, and specifically discloses a self-rescue device in a car, which includes a rescue box and an operating mechanism. wheel assembly, the operating handle connected with the driving wheel assembly, and the self-rescue device in the car is also equipped with a fixed pulley for fixing to the bottom of the well where the car is located. Go around the fixed pulley, then go up through the rescue box and connect with a movable rope head set on the top of the hoistway, or the two ends of the rescue rope are respectively connected with the movable rope head set on the top of the hoistway, and the movable rope head is connected to the elevator by means of the gate line. The brake operating lever connection of the traction machine. The device adopts a purely mechanical structure and is not limited by the electrical system. The leveling operation is simple and easy, and the running distance and direction of the car are not limited.

Description

technical field [0001] The invention relates to elevator rescue equipment, in particular to a self-rescue device in a car. Background technique [0002] Elevators are the most important means of transportation in high-rise buildings, but it is inevitable that they will break down and trap people. The current general situation is that when people are trapped, they can only wait until the rescuers arrive at the scene and rescue them from the outside. During this period, many trapped people couldn't wait, and caused accidents due to improper self-rescue. Elevator manufacturers have made a lot of efforts in this regard, increasing the reliability of components and increasing redundancy. Some manufacturers have also developed self-rescue devices, but these solutions are all based on electrical systems or require electrical components. When the elevator loses power or the backup power supply is damaged, these systems just cannot work, and self-rescue behavior cannot be carried ...
