Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rail production, in particular to a mobile device for hoisting and packaging elevator guide rails. Background Art

[0002] The elevator guide rail is one of the key components of the elevator operation. Its main function is to guide the car and counterweight (counterweight) to slide up and down smoothly in the elevator shaft, and bear the load of the car and counterweight. Elevator guide rails are usually made of high-quality carbon steel, such as Q235 steel, Q345B steel, etc. These materials have good strength and toughness, and can withstand high pressure and wear and tear. The types of elevator guide rails include T-type guide rails, cold-drawn guide rails, hollow guide rails, etc., which require high-precision verticality and straightness during installation to ensure the smooth operation of the elevator. During installation, the guide rail support is generally used for fixing, and the support is tightly connected to the wall of the elevator shaft with expansion screws or welding. The main functions of elevator guide rails include guidance and bearing.

[0003] The production process of elevator guide rails requires primary processing, hot rolling, cold drawing or cold rolling, straightening and cutting, drilling, finishing, surface treatment and inspection. After the production of the elevator guide rails is completed, they need to be packaged and packed for the manufacturer to ship. However, since the elevator guide rails themselves are long and heavy, it is more difficult to pack them manually, and there are certain safety hazards. The packaging area needs to grab the elevator guide rails from the unloading area and place them on the packaging table. The ordinary lifting and moving devices on the market are prone to center of gravity shift when moving the elevator guide rails, resulting in tilting during the lifting process. Severe tilting may even cause the guide rails to fall off, which will not only damage the elevator guide rails, but also pose a threat to surrounding workers. Utility Model Content
