Safety protection device for hoisting machinery

Abstract

The invention provides a safety protection device for hoisting machinery, and relates to the technical field of safety protection of hoisting machinery. The safety protection device for the hoisting machinery comprises a pair of main beams which are connected with a wall and arranged side by side in a spaced mode, wherein a crane is erected between the two main beams, a guardrail mechanism capable of adjusting the height is arranged at the top of each main beam, and a road plate assembly in lap joint with the other main beam is hinged to the interior of any main beam. The main beams are main bodies for bearing the movable crane, and the two main beams and the crane are combined to form a bridge crane. The main beams of the bridge crane longitudinally run along rails laid on elevated frames on the two sides, and the crane can hoist a trolley to transversely run along rails laid on a bridge frame. According to the safety protection device, the guardrail mechanisms are additionally arranged on the main beams so as to protect a maintenance worker, and meanwhile, the two main beams are connected by utilizing the road plate assembly, so that a passage for the worker to advance is formed, and the maintenance working efficiency of the worker is further improved.

Description

technical field [0001] The invention relates to the technical field of safety protection for hoisting machinery, in particular to a safety protection device for hoisting machinery. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] For traditional bridge cranes, there is no safety rail on the inside of the beam, so there will be a protective gap between the beam and the trolley frame, and there is a danger of falling from a high altitude whe...

Problems solved by technology

[0003] For traditional bridge cranes, there is no safety rail on the inside of the beam, so there will be a protective gap between the beam and the trolley frame, and there is a danger of falling from a high altitude when a worker is installing, overhauling or cleaning the beam , thereby endangering the life safety of the staff
