The invention relates to an additional brake which structurally comprises a base, an electromagnet, a pull rod, a brake spring and a brake shoe. The electromagnet is fixed on the base, the brake shoe is a wedge-shaped body, the top surface of the brake shoe is an inclined cambered surface matched with the wheel surface of the brake wheel, and a friction pad is arranged on the top surface of the brake shoe; the brake shoe is arranged on the base in a sliding manner; one end of the pull rod is connected with an armature of the electromagnet; the pull rod is sleeved with the brake spring, one end of the brake spring abuts against the brake shoe, the other end of the brake spring abuts against the electromagnet, and the brake spring is used for pushing the brake shoe into the wedge-shaped space between the wheel face of the brake wheel and the base during braking. The device is small in size, does not occupy the tractor and the peripheral working space, is convenient to install, and can be used in cooperation with various tractors, so that the normative requirement for installing a safety brake on the tractor is met, and the use safety of hoisting equipment and elevator equipment is improved.

    本发明涉及一种附加制动器,其结构包括基座、电磁铁、拉杆、制动弹簧和制动鞋;电磁铁固定在基座上,制动鞋为楔形体,其顶面为与制动轮轮面相合的斜弧面,在其顶面设置有摩擦衬垫;所述制动鞋滑动设置在所述基座上;拉杆的一端与电磁铁的衔铁相接,另一端连接制动鞋;制动弹簧套接在所述拉杆上,其一端顶靠在制动鞋上,其另一端顶靠在电磁铁上,用以在制动时将制动鞋顶入制动轮的轮面与基座之间的楔形空间内。本发明体积小,不占用曳引机及外围的工作空间,且便于安装,能够与各类曳引机配合使用,从而满足曳引机安装安全制动器的规范性要求,提高了起重设备和电梯设备的使用安全性。
