Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, specifically a safety protection device for elevator maintenance. Background Technology

[0002] Elevator maintenance can be carried out on the car top, inside the car, and in the machine room. However, operations inside the car and in the machine room must be subordinate to operations on the car top. For example, during maintenance, elevator maintenance can be performed either inside the car or on the car top. When operating on the car top, maintenance operations inside the car are ineffective. Generally, when operating on the car top, a safety rope needs to be attached. One end of the safety rope is connected to the maintenance worker, and the other end is installed on a hook or guardrail on the car top. When the maintenance worker finishes the operation, they are often eager to test whether the elevator is running normally and forget to untie the safety rope. At this time, the safety rope is dangling, and if it gets caught on the wall side components, it will cause dragging, seriously affecting the life safety of the maintenance personnel. Therefore, a safety protection device for elevator maintenance is proposed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection device for elevator maintenance, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for elevator maintenance, comprising a safety lock, a connecting ring, and a first storage mechanism;

[0005] The safety buckle is in two sets, and a connecting ring is installed at the bottom of each safety buckle. A first storage mechanism is fixedly connected to the other end of the connecting ring on one side, and a second storage mechanism is fixedly connected to the other end of the connecting ring on the other side. A safety rope is fixedly connected inside both the first storage mechanism and the second storage mechanism.

[0006] The first storage mechanism includes a first storage sleeve, a first fixing ring, and a first spring. One side of the first storage sleeve is fixedly connected to a connecting ring. A safety rope is fixedly connected inside the first storage sleeve. The first storage sleeve has a first fixing ring and a first moving ring inside. The inside of the first fixing ring is fixedly connected to the safety rope. A first spring is fixedly connected to one end face of the first fixing ring and the first moving ring. A first moving frame is fixedly connected to the outside of the first moving ring. The outside of the first moving frame is slidably connected to the first storage sleeve.

[0007] The second storage mechanism includes a second storage sleeve, a second fixing ring, and a second spring. One side of the second storage sleeve is fixedly connected to a connecting ring. A safety rope is fixedly connected inside the second storage sleeve. The second storage sleeve contains a second fixing ring and a second movable ring. The inside of the second fixing ring is fixedly connected to the safety rope. A second spring is fixedly connected to one end face of the second fixing ring and the second movable ring. A second movable frame is fixedly connected to the outside of the second movable ring. The outside of the second movable frame is slidably connected to the second storage sleeve.

[0008] Furthermore, a first movable magnet is fixedly connected to one side of the first movable frame, and a first fixed magnet is fixedly connected to the surface of the first storage sleeve. The opposite end faces of the first movable magnet and the first fixed magnet are arranged with opposite poles.

[0009] Furthermore, a second movable magnet is fixedly connected to one side of the second movable frame, and a second fixed magnet is fixedly connected to the surface of the second storage sleeve. The opposite end faces of the second movable magnet and the second fixed magnet are arranged with opposite poles.

[0010] Generally, a safety rope is required when operating on the top of the elevator car. One end of the safety rope is connected to the maintenance worker, and the other end is installed on a hook or guardrail on the top of the car. When the maintenance worker finishes the operation, they are often eager to test whether the elevator is running normally and forget to untie the safety rope. At this time, the safety rope is dangling, and if it gets caught on the wall components, it will cause dragging, seriously endangering the life safety of the maintenance personnel. In use, the safety rope is set inside the first and second storage mechanisms. When in use, the first and second storage mechanisms are separated, and the safety rope inside is exposed. Under the action of the first and second springs, a part of the safety rope can be placed inside the first and second storage sleeves. This can prevent the safety rope from dangling and getting caught on the wall components, effectively avoiding the problem of the safety rope dragging the safety worker.

[0011] Furthermore, an inclined groove is provided on one outer end of the first storage sleeve, and the inclined groove is inclined on the inner bottom layer.

[0012] Furthermore, a rotating plate is rotatably connected to one side of the second storage sleeve, and a third spring is fixedly connected to one side of the rotating plate, with the other end of the third spring fixedly connected to the second storage sleeve.

[0013] Furthermore, the outer diameter of the side of the second storage sleeve facing the first storage sleeve is the same as the inner diameter of the first storage sleeve.

[0014] The rotating plate is located inside the inclined groove, and then slides into the limiting groove on one side of the inclined groove. At this time, under the action of the third spring, the second storage sleeve and the first storage sleeve are tightly fixed to prevent them from separating, making it very convenient to carry.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In use, the safety rope of this utility model is set inside the first and second storage mechanisms. When in use, the safety rope is exposed when the first and second storage mechanisms are separated. Under the action of the first and second springs, a part of the safety rope can be located inside the first and second storage sleeves. This can prevent the safety rope from dangling and getting caught on the wall components, and can effectively avoid the problem of the safety rope dragging the safety officer.

[0017] When storing the safety rope, simply pull the first moving frame to move the first moving ring. The first moving ring then moves the first spring and the first fixed ring, placing the safety rope inside the first storage sleeve. Then, pull the second moving frame to move the second moving ring, which in turn moves the second spring and the second fixed ring, storing the safety rope inside the second storage sleeve. By connecting the first and second storage sleeves, the overall storage of the safety rope is completed, which is very convenient.

[0018] Furthermore, the rotating plate is located inside the inclined groove, and then slides into the limiting groove on one side of the inclined groove. At this time, under the action of the third spring, the second storage sleeve and the first storage sleeve are tightly fixed to prevent them from separating, making it very convenient to carry.

[0031] Generally, a safety rope is required when operating on the top of the elevator car. One end of the safety rope is connected to the maintenance worker, and the other end is installed on a hook or guardrail on the top of the car. When the maintenance worker finishes the operation, they are often eager to test whether the elevator is running normally and forget to untie the safety rope. At this time, the safety rope is dangling, and if it gets caught on the wall components, it will cause dragging, which will seriously affect the safety of the maintenance personnel. In use, the safety rope 4 is set inside the first storage mechanism 3 and the second storage mechanism 5. When in use, the first storage mechanism 3 and the second storage mechanism 5 are separated, and the safety rope 4 is exposed.
