Problems solved by technology

The reason is that the impact resistance of the existing car roof guardrails is not enough, and the joints of the guardrails are prone to fail and fall apart under impact
[0003] Therefore, the existing car roof guardrail has the problems of low structural strength and poor impact resistance

Abstract

The invention discloses an anti-impact elevator car ceiling guardrail. The anti-impact elevator car ceiling guardrail comprises U-shaped horizontal guard bars. The guard bars are connected with standcolumns fixed to a car ceiling. A buffer device is arranged at the joint of every two guard bars. Each buffer device comprises two resisting arms and a limiting box. Each resisting arm comprises an arc-shaped strip with the T-shaped cross section, the end of the arc-shaped strip is provided with a sliding sleeve arranged on one side guard bar or the rear guard bar in a sleeving mode, and the arc-shaped strip is provided with a rack. Each limiting box is provided with an arc-shaped groove in sliding fit with the corresponding arc-shaped strip. Each limiting box is internally provided with a gear matched with the corresponding racks. A clockwork spring is arranged at the junction between each gear and the corresponding limiting box. The anti-impact elevator car ceiling guardrail has the characteristics of being high in structural strength and good in impact resistance. Besides, the anti-impact elevator car ceiling guardrail is concise and stable in structure, simple in manufacturing process and low in cost.

Description

technical field [0001] The invention relates to an elevator device, in particular to an anti-shock elevator car top guardrail. Background technique [0002] When the outer edge of the car roof has a free distance of more than 0.30m in the horizontal direction, the car roof should be equipped with guardrails. Even when the car top guardrail is installed, there are still accidents where maintenance personnel are injured due to the problem of the car top guardrail. Trace it to its cause, be that the anti-shock ability of existing car roof guardrail is not enough, and the junction of guardrail easily loses efficacy and falls apart under impact. [0003] Therefore, the existing car roof guardrail has the problems of low structural strength and poor impact resistance. Contents of the invention [0004] The object of the present invention is to provide an anti-shock elevator car roof guardrail. The invention has the characteristics of high structural strength and good impact r...
