The counterweight device comprises a traction wheel, a counterweight side machine room diversion sheave, a counterweight side rope head assembly, a counterweight frame and a counterweight diversion sheave assembly, the counterweight diversion sheave assembly comprises three counterweight diversion sheaves arranged on the counterweight frame, and the three counterweight diversion sheaves are arranged in a triangular shape; the two counter-weight diversion sheaves are respectively a first counter-weight diversion sheave and two second counter-weight diversion sheaves; the counterweight side machine room diversion sheave and the counterweight side rope head assembly are located on the two sides of the traction sheave respectively. A steel wire rope is wound on the traction wheel, and one end of the steel wire rope is wound on the first counterweight diversion sheave after being pulled out of the traction wheel, then is wound on the counterweight side machine room diversion sheave, penetrates through the two second counterweight diversion sheaves and then is fixed to the counterweight side rope head assembly. According to the counterweight device for the freight elevator, the center of the counterweight frame can be close to the center of the elevator car, the counterweight diversion sheave assemblies are distributed on the two sides of the center of the elevator car, the counterweight side machine room diversion sheaves and the counterweight side rope head assemblies are distributed on the two sides of the center of the elevator car, and the stress state of the bearing beam can be improved.
本发明公开了一种用于载货电梯的对重装置,包括曳引轮、对重侧机房反绳轮、对重侧绳头组件、对重架和对重反绳轮组件,对重反绳轮组件包括设于对重架的三个对重反绳轮,三个对重反绳轮呈品字形排布,分别为一个第一对重反绳轮和两个第二对重反绳轮;对重侧机房反绳轮和对重侧绳头组件分别位于曳引轮的两侧;曳引轮上绕设有钢丝绳,钢丝绳的一端从曳引轮上拉出后绕到第一对重反绳轮,然后绕过对重侧机房反绳轮,再穿过两个第二对重反绳轮后与对重侧绳头组件固定。本发明一种用于载货电梯的对重装置,可使对重架中心接近轿厢中心,对重反绳轮组件分布在轿厢中心两侧,对重侧机房反绳轮和对重侧绳头组件分布在轿厢中心两侧,可改善承重梁的受力状态。
