The invention discloses a hoisting device for mechanical maintenance. The device comprises a bottom plate, wherein an elevating gear is fixedly arranged at the top of the bottom plate; a base plate isarranged at the top of the elevating gear; a guard rail is fixedly connected to the top of the base plate; a square frame is fixedly connected to the top of the guard rail; connecting boxes are fixedly connected to the front face and the back face of the bottom plate; screw rods are arranged at the tops of the connecting boxes; and the bottom ends of the screw rods penetrate through the bottoms of the connecting boxes. According to the hoisting device, a transmission mechanism drives the screw rods to rotate and then the screw rods drive fixing sleeves to be pressed on the ground through threaded sleeves, the contact area and friction force between the bottom plate and the ground are increased, the hoisting device has an advantage of being good in stability, the problems that an existinghoisting device is poor in stability due to the fact that the position is fixed only by manually rotating the screw rod, and meanwhile, the screw rod is prone to rotating are solved, the safety of thehoisting device is improved to a certain degree, and people can use the hoisting device conveniently.

    本发明公开了一种机械检修用提升装置,包括底板,所述底板的顶部固定安装有升降装置,所述升降装置的顶部设置有垫板,所述垫板的顶部固定连接有防护栏,所述防护栏的顶部固定连接有方框,所述底板的正面与背面均固定连接有连接箱,所述连接箱的顶部设置有螺杆,所述螺杆的底端贯穿至连接箱的底部,本发明由传动机构带动螺杆转动,再由螺杆通过螺套带动固定套压紧在地面,增加底板与地面的接触面积和摩擦力,从而具备了稳定性较好的优点,解决了现有的提升装置只通过手动转动螺杆进行位置固定,稳定性较差,同时螺杆容易出现回转的问题,一定程度的提高了提升装置的安全性,便于人们使用。
