Bridge crane with anti-collision early warning function

Abstract

The invention discloses a bridge crane with an anti-collision early warning function. The bridge crane comprises a bridge crane body, and further comprises fixing plates, positioning plates, power connection terminals, conductive blocks, insulating columns, detection plates, proximity sensors I, a fixing sleeve, an alarm, electric push rods, outer ring frames, communication sleeves, proximity sensors II and suction air pumps. Firstly, through a touch separation power-off design, when the bridge crane body moves front and back to touch an obstacle, power-off between a power source and the bridge crane body can be achieved through extrusion force, so that the problem that great potential safety hazards are caused due to the fact that the bridge crane body collides with the obstacle is solved; secondly, a multi-position proximity sensing alarm mechanism is matched, and an alarm can be given after the obstacle is detected, so that the purpose of reminding an operator is achieved; and finally, due to the adoption of a multi-mode adjusting structure, the detection length and the diameter can be adjusted as required, so that the anti-collision early warning function is also realized on the basis of avoiding the interference influence on a lifted object, the practicability is expanded, and the bridge crane has high popularization and application values.

Description

technical field [0001] The invention relates to the technical field of bridge cranes, in particular to a bridge crane with an anti-collision warning function. Background technique [0002] The bridge crane is a lifting device that is placed horizontally over the workshop, warehouse and stockyard for material lifting. Its two ends are located on tall cement columns or metal supports, which are shaped like bridges. The rails on the elevated sides on both sides run longitudinally, 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 lifting machinery with the widest range of use and the largest number. It is an important tool and equipment to realize the mechanization and automation of the production process in transportation. Therefore, single-girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an overhead crane with an anti-collision early warning function to solve the problem that the existing traditional overhead crane easily touches surrounding obstacles during operation and movement, which not only causes damage to itself and the surrounding objects. In addition, it also brings great hidden dangers to personnel safety.
