Safety protection device for hoisting machinery

Abstract

The invention discloses a safety protection device for hoisting machinery, which comprises a base. The upper end of the base is fixedly connected with four sets of bottom plates at equidistant distances. The upper ends of the two groups of support columns at the rear are fixedly connected with horizontal plates, and the horizontal plates are fixedly connected with lifting devices. The middle part of the upper end of the base is fixedly connected with four sets of connecting columns at equal distances, and the upper ends of the four sets of connecting columns A base is fixedly connected together, and four sets of sliding devices are fixedly connected to the upper end of the base at equidistant distances, and two sets of connecting seats are fixedly connected to the left part and the right part of the upper end of the base, and the four sets of connecting seats move together A transmission device is interspersed and connected, and the left part and the right part of the transmission device are both fixedly interspersed and connected with a lifting device. The safety protection device for hoisting machinery according to the present invention is provided with a transmission device, so that the lifting device can drive the pressing plate to fasten the articles.

Description

technical field [0001] The invention relates to the field of hoisting machinery safety, in particular to a hoisting machinery safety protection device. Background technique [0002] Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal moving of heavy objects. Its scope is defined as lifts with a rated lifting capacity greater than or equal to 0.5t; Cranes equal to 2m and electric hoists with fixed load-bearing forms, etc. Lifting operation is an industrial process of transporting mechanical equipment or other objects from one place to another. The working process generally includes lifting, running, falling and returning to the original place. Positioning and other steps, and when moving larger objects, certain dangers may occur. 1. Since the current hoisting machinery cannot fix the objects when retrieving materials, there are certain risks in the lifting process of the objects. 2. 1. There is no certain buff...

[0002] Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal moving of heavy objects. Its scope is defined as lifts with a rated lifting capacity greater than or equal to 0.5t; Cranes equal to 2m and electric hoists with fixed load-bearing forms, etc. Lifting operation is an industrial process of transporting mechanical equipment or other objects from one place to another. The working process generally includes lifting, running, falling and returning to the original place. Positioning and other steps, and when moving larger objects, certain dangers may occur. 1. Since the current hoisting machinery cannot fix the objects when retrieving materials, there are certain risks in the lifting process of the objects. 2. 1. There is no certain buffer when retrieving materials, which leads to unstable lifting of the machine and is prone to danger. 3. The existing device is easy to cause objects to collide, resulting in damage to the objects. Therefore, we propose a lifting machinery safety protection device
