A winch positioning device for a crane comprises a supporting frame, rectangular grooves are formed in sidewalls of the supporting frame, winches are rotatably connected to one sides, away from each other, of the two rectangular grooves, second fixing rings are arranged at the left side and the right side of each winch, anti-skid grooves are formed in one sides, away from each other, of the two second fixing rings, second clamping teeth are distributed at one sides, away from each other, of the two second fixing rings in an array mode, two cavities are symmetrically formed in the winch, first electric telescopic rods are arranged at one ends, close to each other, of the two cavities, moving blocks are arranged at the outer ends of the first electric telescopic rods, the moving blocks are slidably connected to the interiors of the cavities, and first rectangular through holes are distributed in the side surfaces of the cavities in an array mode. According to the device, the winch is located after being prevented from rotating through anti-skid rubber blocks and the anti-skid grooves, the situation that the impact force is too large when the winch is located is prevented, the positioning device is prevented from being damaged, and the safety of the crane is improved.
一种起重机用绞盘定位装置,包括支撑架,所述支撑架的侧壁均开设有矩形凹槽,两个矩形凹槽相互远离的一侧转动连接有绞盘,所述绞盘的左右两侧均设有固定环二,两个固定环二相互远离的一侧均开设有防滑凹槽,位于防滑凹槽的内部在两个固定环二相互远离的一侧阵列分布有卡齿二,绞盘的内部对称设有两个空腔,两个空腔相互靠近的一端设有电动伸缩杆一,电动伸缩杆一的外端设有移动块,移动块的滑动连接在空腔的内部,空腔的侧面阵列分布有矩形通孔一;本发明通过防滑橡胶块和防滑凹槽对绞盘进行防转动后再进行定位,防止绞盘定位时冲击力过大,避免造成该定位装置发生损坏,提高了起重机的安全性。
