Description

Technical Field

[0001] The utility model relates to an elevator car guide rail structure and belongs to the technical field of elevator guide rails. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types based on the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator. Therefore, the guide rails should be selected according to the elevator speed and load.

[0003] The existing patent number is CN220055948U, which is an elevator car guide rail structure. This device sets a hollow part in the guide rail body. When it is inconvenient to keep the actual material thickness of the guide rail body, a plug-in extension head can be set in the hollow part. The plug-in extension head is inserted into the hollow part of the other guide rail body to complete the positioning of the two guide rail bodies. When the two guide rail bodies are spliced, the reserved plug-in head at the end of the traditional solid rail needs to be thinned, which causes a decrease in strength. The hollow part of the connection is filled with foam material, and the reinforcing rib part between the mounting part and the guide part can ensure the connection. The structural strength is improved and the connection flatness of the two guide rail bodies is increased. However, this device requires multiple bolts for splicing and installation when in use, and the process is relatively cumbersome. When there are many guide rails, the installation is time-consuming and labor-intensive, which affects the convenience of installation of the guide rails. In addition, during the use of the guide rails, the multiple bolt structures provided therein are protruding structures, which are easy to affect the movement of the car after the bolts are used for a long time and loosen and move outward; and this device is installed in direct contact with the elevator shaft wall when in use, which is easy to cause a large amount of noise generated by the operation of the car to spread, thereby increasing noise pollution and affecting the living comfort of people around.
