The winch mechanism comprises a control unit, a box body, a worm, a worm gear, a chain wheel, a transmission shaft, a motor and a zipper, wherein the worm, the worm gear, the chain wheel and the transmission shaft are assembled in the box body, the motor is assembled on the outer side of the box body and used for driving the worm to rotate, and the zipper penetrates through the box body and used for pulling a heavy object. According to the winch mechanism, power transmission of the worm gear and the worm is stable, the self-locking function is achieved to prevent sliding, the pulling force can be improved through the combination mode of the zipper and the chain wheel, and the wheel diameter of the chain wheel does not need to be increased. Compared with an existing winch adopting a winding drum, the winch mechanism disclosed by the invention is relatively small in size and relatively stable in gravity center, does not need to be provided with a special winding drum braking system, and is beneficial to saving the cost.
本发明公开了一种绞车机构,包括控制单元、箱体、装配在所述箱体中的蜗杆、蜗轮、链轮及传动轴、装配在所述箱体的外侧且用于驱动所述蜗杆转动的马达和穿过所述箱体且用于拉动重物的拉链。本发明公开的绞车机构,蜗轮与蜗杆传递动力稳定且具有自锁功能以防止溜车,拉链与链轮的组合方式能够提高拉力,也无需增加链轮的轮径。与现有的采用卷筒的绞车相比,本发明公开的绞车机构,体积相对较小,重心相对稳定,无需配置专门的卷筒制动系统,利于节约成本。
