The invention discloses an elevator safety clamp wedge block. The elevator safety clamp wedge block comprises a wedge block body and a guide rail sweeping device. The lower portion of the guide rail contact face of the wedge block body is downwards concaved, and the upper portion is a braking face. The guide rail sweeping device comprises a retainer, a spring and a tooth-shaped shoe. The retaineris fixed to the downward concave position of the lower portion of the guide rail contact face of the wedge block body. A bottom plate of the tooth-shaped shoe is clamped to the retainer. The tooth face of the tooth-shaped shoe upwards gets out of the retainer and is higher than the braking face. The spring is placed between the bottom plate of the tooth-shaped shoe and the downward concave position of the lower portion of the guide rail contact face of the wedge block body. According to the elevator safety clamp wedge block, when a safety clamp acts, oil dirt on the surface of a guide rail iseffectively swept, the guide rail face making contact with the braking face of the wedge block is swept, and the braking stability of the safety clamp is enhanced.

    本发明公开了一种电梯安全钳楔块,其包括楔块本体、导轨清扫装置;楔块本体的导轨接触面下部下凹,上部为制动面;导轨清扫装置包括保持架、弹簧及齿形靴;保持架固定在楔块本体的导轨接触面下部下凹处;齿形靴的底板卡合在保持架下;齿形靴的齿面向上探出保持架并高出制动面;弹簧放置在齿形靴的底板同楔块本体的导轨接触面下部下凹处之间。本发明的电梯安全钳楔块,能在安全钳动作时对导轨表面的油污进行有效清扫,使得楔块的制动面接触的导轨面是经过清扫的,增强安全钳制动的稳定性。
