Hoisting device for mechanical maintenance

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mechanical maintenance, in particular to a lifting device for mechanical maintenance. Background technique [0002] Machinery refers to the general term of machines and mechanisms. Machinery is a tool device that can help people reduce the difficulty of work or save labor. Items such as chopsticks, brooms, and tweezers can be called machinery. They are simple machines, and complex machines are made of Two or more simple machines are composed, and these more complex machines are usually called machines. From the point of view of structure and movement, there is no difference between mechanisms and machines, and they are generally called machines. [0003] However, some large-scale machinery usually needs a lifting device to lift the maintenance personnel to a certain height for maintenance during maintenance. However, the existing lifting device only fixes the position by manually turning the screw, which ...
