Abstract

The invention provides a safety guardrail for an elevator car roof. The safety guardrail comprises a guardrail body, wherein the guardrail body comprises a rear guardrail as well as a left guardrail and a right guardrail which are arranged at the two sides of the rear guardrail; the rear guardrail comprises a first cross strut and a second cross strut; one end of the first cross strut and one end of the second cross strut, which are at the same side, are simultaneously connected to a first vertical strut; the other end of the first cross stud and the other end of the second cross strut, which are at the same side, are simultaneously connected to a second vertical strut; the left guardrail comprises a third cross strut and a fourth cross strut; one end of the third cross strut and one end of the fourth cross strut, which are at the same side, are simultaneously connected to the second vertical strut; the other end of the third cross strut and the other end of the fourth cross strut, which are at the same side, are simultaneously connected to a third vertical strut; the right guardrail comprises a fifth cross strut and a sixth cross strut which are arranged in parallel vertically; one end of the fifth cross strut and one end of the sixth cross strut, which are at the same side, are simultaneously connected to the first vertical strut, and the other end of the fifth cross strut and the other end of the sixth cross strut, which are at the same side, are simultaneously connected to a fourth vertical strut; and the guardrail is a structure which is in the shape of U, U with opening facing rightwards or C. A supporting frame is telescopic pole structure. The safety guardrail is stable and reliable in structure, can regulate mounting height, on the supporting frame, of the guardrail body, and is strong in adaptation.

Description

technical field [0001] The invention belongs to the technical field of elevator accessories, and in particular relates to an elevator car top safety guardrail. Background technique [0002] With the widespread use of elevators, it has become a must-use means of transportation for various people in buildings. With the continuous development of elevator applications, there are currently many elevator shafts with low top floor heights on the market. The top floor is often very low, while the overall height of the old-fashioned guardrail is fixed, and the car roof guardrail becomes the highest part of the car. When the height of the top floor of the elevator shaft is insufficient, the car roof space will not be enough to install the car roof guardrail. However, since operators need to work on the car top during elevator installation and maintenance, the absence of car top guardrails will greatly increase the risk of operators falling into the hoistway, and cannot guarantee the ...
