Lifting appliance for hanging a plurality of door and window frames

Abstract

A lifting appliance for hanging a plurality of door and window frames comprises a lifting appliance body; the lifting appliance body comprises a frame body; a vertical rod is connected to the frame body; a first lifting hook is arranged at the end of the vertical rod; and at least two second lifting hooks are connected to the frame body. On the one hand, the plurality of door and window frames canbe hung, convenience is greatly improved, the structure is simple, the cost is low, no ground space needs to be occupied, and the utilization rate of the ground space is effectively increased; on theother 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; and furthermore, repair welding, cleaning and other work can be conducted on the window frame hung in the air, so that it is not needed to find which one needs repair welding from door and window frames stacked on the ground, thework efficiency is greatly improved, cleaning is convenient, and cleaning work of the front face and the back face can be achieved without overturning the front face and the back face.

Description

technical field [0001] The invention relates to a door and window frame hanging device, in particular to a hanger used for hanging multiple door and window frames. 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. When repair welding is required, it is also carried out on the ground, but the door and window frames are usually stacked...

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, which can solve the problems of low ground space utilization rate caused by stacking window frames or door frames on the ground and low work efficiency during repair welding, and can also hang multiple hangers at the same time. The function of the door and window frame
