Deformation-resisting elevator toe guard

Abstract

The invention discloses a deformation-resisting elevator toe guard which comprises a supporting frame. A U-shaped groove is formed in the end portion of the supporting frame. The outer side of the supporting frame is connected with a fixing plate through multiple long bar holes. Multiple lifting hooks are arranged at the upper end of the fixing plate. One ends of the lifting hooks are connected with the supporting frame through rectangular holes. A limiting bracket is arranged on the inner side of the fixing plate. The upper end of the limiting bracket is connected with the supporting frame. Positioning angle steel fixed to the inner side of the fixing plate is arranged on the two sides of the limiting bracket. The upper end of the positioning angle steel is attached to the bottom of the U-shaped groove. A trapezoidal groove is formed in the bottom of the fixing plate, and multiple strengthening rib plates connected with the fixing plate are arranged in the trapezoidal groove. By meansof the deformation-resisting elevator toe guard, due to cooperation of the positioning angle steel and the lifting hooks, a limiting effect can be achieved on the fixing plate; and the stress strength of the fixing plate can be effectively improved through the limiting bracket, so that the toe guard has the beneficial effects of being high in deformation-resisting capability and good in safety.

Description

technical field [0001] The invention relates to a toe guard, in particular to a deformation-resistant elevator toe guard. Background technique [0002] Elevator toe guards are usually installed at the bottom of the bridge car sill, and its function is to prevent the toes from being hurt by shearing when the car door is opened before the end of leveling or when the car sill is higher than the landing door sill after leveling. However, due to the low strength of the existing elevator toe guards, the elevator toe guards will be deformed and bent to varying degrees after being stressed, thereby affecting the protective effect of the toe guards; The start-stop and variable-speed movement will also cause a certain vibration when moving, so that the toe guard needs to withstand the vibration and pressure brought by the elevator bridge for a long time, resulting in the problem of loosening or falling of the toe guard after long-term use. Certain security risks. Therefore, the exis...

Problems solved by technology

However, due to the low strength of the existing elevator toe guards, the elevator toe guards will be deformed and bent to varying degrees after being stressed, thereby affecting the protective effect of the toe guards; The start-stop and variable-speed movement will also cause a certain vibration when moving, so that the toe guard needs to withstand the vibration and pressure brought by the elevator bridge for a long time, resulting in the problem of loosening or falling of the toe guard after long-term use. certain security risks

Therefore, existing toe guards have the problems of weak anti-deformation ability and poor safety
