Description

Technical Field

[0001] The utility model relates to the technical field of elevator auxiliary equipment, and particularly discloses a stability clamping device for an elevator. Background Art

[0002] An elevator is a multifunctional lifting device primarily used for vertical transportation of materials or personnel. It achieves this function through hydraulic oil pressure transmission, resulting in exceptional stability and load-bearing capacity, making it suitable for transporting materials between production lines or floors. Currently, to increase elevator flexibility, most elevators require a mobile chassis, allowing them to be moved between different operating locations. This not only facilitates material transportation but also improves production efficiency.

[0003] The operator can place the barrel or box carrying the material on the lifting platform of the elevator, and transport it to other working areas by moving the chassis and lifting it to the corresponding height. The operator can then pour it into the production equipment in the working area. In the actual production operation process, the material box generally needs to carry solid objects or fluid materials. During the movement and lifting process of the elevator, the material box is very likely to shake due to the movement of the elevator, causing the material inside it to overflow from the material box, thereby causing production waste. In addition, during the unloading process of the material box, it is necessary to manually push the material box to turn it over, so that the material inside it can be poured out. In the above process, not only does it require a lot of physical strength from the operator and is inefficient, but the material is also easily splashed onto the operator during the turning and pouring process, thus creating a safety hazard. Utility Model Content
