Description
Technical Field
[0001] The utility model belongs to the technical field of elevator accessories, and in particular relates to a position limiting auxiliary device for a guide shoe of a counterweight of an inclined elevator. Background Art
[0002] An elevator is a kind of lift powered by an electric motor. Conventionally, regardless of its driving mode, elevators are a general term for vertical transportation tools in buildings. As a modern means of transportation, it plays an important role in high-rise building transportation. The above-mentioned inclined elevators, as an important branch of the development of special elevators, are mainly used to complete the lifting of some slope-shaped tracks. Its car runs along the inclined guide rails in the inclined shaft. At present, inclined elevators are developing rapidly, and it is recognized that inclined elevators are more labor-saving and energy-saving than vertical transportation traction elevators. At the same time, they can effectively meet the transportation needs of special places in subways, stations, roads and bridges, scenic spots and some special buildings. In addition, inclined elevators are the best choice to solve public barrier-free transportation.
[0003] The counterweight is a component of the elevator traction system. Its function is to balance the weight of the car and is connected to the top of the car through the traction wire rope. The counterweight guide shoe is also an important guiding component of the elevator counterweight. It is a component used to achieve relative sliding or rolling of the counterweight. Specifically, it is installed on the counterweight guide shoe and cooperates with the slide rail. At the same time, the counterweight guide shoe is used to support the sliding of the counterweight and limit its direction, so that the counterweight can only move up and down along the guide rail. The counterweight guide shoe of the inclined elevator needs to have a good guiding function, and also has very strict requirements on its specific structural form, strength, safety, etc. Existing inclined elevators are provided with T-shaped guide rails that match the counterweight guide shoes. During the specific operation, the counterweight guide shoe structure is often unable to move smoothly along the guide rail and is prone to shaking in the horizontal direction, which causes the existing counterweight guide shoe structure to easily interfere with or even violently collide with the light-loaded inclined elevator guide rail components. In severe cases, emergency safety accidents may even occur. Of course, there are also situations where the counterweight guide shoe mechanism cannot effectively cooperate with the guide rail components, so that the stability and safety of the operation cannot be effectively guaranteed; in addition, during the long-term use of the existing inclined elevator structure in the outdoor environment, garbage and foreign objects such as leaves, stones, snow, sludge, and hard debris are easily accumulated on the surface of the guide rail. Once these garbage and foreign objects enter the counterweight guide shoe mechanism and directly contact its internal components, they are easy to scratch the components or rollers in the counterweight guide shoe mechanism, which brings adverse factors to the smooth operation, thereby affecting the service life of the counterweight guide shoe structure, and making it impossible to achieve smooth cooperation between the guide rail and the counterweight guide shoe mechanism, and these garbage and foreign objects are difficult to clean up in time.
