Technical Field

[0001] The utility model relates to the field of elevators, in particular to an L-shaped elevator car top guardrail mechanism with adjustable angle. Background Art

[0002] An L-shaped elevator refers to an elevator with right-angled doors, that is, the entrance elevator door and the exit elevator door are located on two adjacent right-angled sides of the car. The upper beam of this L-shaped elevator is located on the diagonal line of the car, and the traditional guardrail structure is not suitable for this elevator.

[0003] The Chinese patent with publication number CN210884818U discloses a vertical car top guardrail installation structure, including a car top platform, a car top cross beam assembly and an upper beam, the car top cross beam assembly is fixedly installed on the car top platform, the upper beam is fixedly installed on the two diagonal parts of the car top cross beam assembly, and a guardrail is fixedly installed on the car top platform. The guardrail includes two vertical guardrail sections and a diagonal guardrail section. The two vertical guardrail sections are located on the car top platform inside two adjacent cross beams of the car top cross beam assembly and are parallel to the two adjacent cross beams respectively. The diagonal guardrail section is connected between the two vertical guardrail sections and straddled on the upper part of the upper beam. The guardrail structure design in this car top guardrail installation structure is scientific and reasonable, and is suitable for the car top protection needs of right-angle door cabin elevators.

[0004] However, the above guardrail structure still has the following problems: due to the different widths and depths of the elevator cars, the inclinations of the upper beams are also different. The car top guardrail needs to be adjusted along with the inclination of the upper beam during installation, which brings considerable trouble to the installation. Utility Model Content
