The invention relates to the technical field of elevator braking, and discloses an elevator brake for carrying construction elevator building materials, which comprises brake arms, a motorized wheel is placed below the position between the two brake arms, the brake arm positioned in the middle of the motorized wheel is fixedly connected with a brake shoe seat, one side of the brake shoe seat is fixedly connected with a brake shoe, and the brake shoe is fixedly connected with a brake block. A vertical groove is formed in the surface of the motorized wheel, a transverse groove is formed in the motorized wheel located on one side of the vertical groove, and a rubber film is fixedly connected into the transverse groove of the motorized wheel in a sleeved mode. The vertical groove is formed in the surface of the motorized wheel, the protruding pieces are arranged in the vertical groove, the roughness degree of the contact surface between the motorized wheel and the brake shoe is increased through uniform distribution of the protruding pieces, and the situation that the surface of the motorized wheel becomes smooth due to long-time friction braking is effectively prevented; and meanwhile, integrated arrangement of the brake shoe is changed into the first brake shoe and the second brake shoe, and the brake effect is effectively improved through cooperative use of the protruding piece, the first brake shoe and the second brake shoe.

本发明涉及电梯制动技术领域，且公开了一种用于施工电梯建材搬运的电梯制动器，包括制动臂，两个所述制动臂之间的下方放置有机动轮，位于所述机动轮中部的制动臂固定连接闸瓦座，所述闸瓦座的一侧固定连接有制动闸瓦，所述机动轮的表面开设有竖槽，且位于竖槽一侧的机动轮内部开设有横槽，所述机动轮的横槽内部固定套接橡胶膜。本发明通过在机动轮的表面开设竖槽，并在竖槽内设置凸起件，凸起件的均匀分布使得机动轮与制动闸瓦之间的接触面粗糙程度增加，有效防止了机动轮因长时间摩擦制动而表面变光滑，同时将制动闸瓦的一体式设置变为第一闸瓦和第二闸瓦两部分，凸起件与第一闸瓦、第二闸瓦的配合使用有效提高了制动效果。
