Lifting appliance for door frame and window frame

Abstract

A lifting appliance for a door frame and a window frame comprises a lifting appliance body, the lifting appliance body comprises a transverse rod and a vertical rod, a first lifting hook is arranged at one end of the vertical rod, the other end of the vertical rod is connected with the transverse rod, and second lifting hooks are arranged at the lower end of the transverse rod. According to the lifting appliance, on one hand, the structure is simple, the door frame and the window frame can be hung only by hanging the first lifting hook of the lifting appliance body on a lifting frame and thenhooking the window frame through the second lifting hooks, so that the window frame can be subjected to paint spraying, cleaning and other work, the work efficiency is greatly improved, and no groundspace is occupied; and on the other hand, the lifting appliance body is of a modular structure, can be folded at any time after being used, and is convenient to stack and transport and small in size.

Description

technical field [0001] The invention relates to a door and window frame hanging device, in particular to a door and window frame hanger. Background technique [0002] The window frame is the frame part of the window, the hollow part of the window frame is used for installing the window, and the edge of the window frame is used for connecting with the wall. The door frame is the frame part of the door body, and the principle is similar to the window frame. After the existing door and window frames (door frames or window frames) are prepared, they are directly stacked on the ground, which greatly increases the occupied space on the ground. If there are many door and window frames, the ground will basically be occupied by the door and window frames. In addition, the existing door and window frames sometimes undergo repair welding.

AI Technical Summary

Problems solved by technology

After the existing door and window frames (door frames or window frames) are prepared, they are directly stacked on the ground, which greatly increases the occupied space on the ground. If there are many door and window frames, the ground will basically be occupied by the door and window frames

In addition, the existing door and window frames sometimes undergo repair welding. When repair welding is required, it is also carried out on the ground, but the door and window frames are usually stacked one by one, so it is necessary to find out which one to repair. Then repair welding, the work efficiency is greatly reduced

Therefore, the present invention urgently needs to design a spreader with simple structure and low cost, so as to solve the problems of low utilization rate of ground space caused by stacking window frames or door frames on the ground and low work efficiency during repair welding.
