Unmanned crane with steel wire rope winding detecting function

Abstract

The invention discloses an unmanned crane with a steel wire rope winding detecting function. The unmanned crane comprises a winding drum, a left steel wire rope, a right steel wire rope and a supporting frame. The winding drum is mounted on the supporting frame, one end of the left steel wire rope and one end of the right steel wire rope are wound around the winding drum, and the other end of theleft steel wire rope and the other end of the right steel wire rope droop to be connected with a jacking mechanism together. A controller and a detecting device are further included. The detecting device comprises an upper support, a detecting cable, a balance weight and a first proximity switch. The upper support is fixed to the supporting frame, and the first proximity switch is fixed to the upper support. The front end of the detecting cable is fixed to the supporting frame, the middle of the detecting cable stretches across the supporting frame and penetrates the space between the left steel wire rope and the right steel wire rope, the tail of the detecting cable is movably attached to the upper support, and the tail end of the detecting cable is wound around the top of the upper support, droops and is connected with the balance weight. The balance weight and the first proximity switch are arranged in an aligned manner, and the first proximity switch and the controller are in signal correlation. The unmanned crane has the advantages that the winding phenomenon of the steel wire ropes of the unmanned crane is detected through the detecting device in the first place, and subsequent accidents are avoided.

Description

technical field [0001] The invention relates to an unmanned driving vehicle with a wire rope winding detection function, belonging to the technical field of unmanned driving vehicles. Background technique [0002] Crane is a general term for cranes such as cranes, aircraft vehicles, and overhead cranes. Its basic mechanism usually includes a drum, a wire rope, and a lifting mechanism. For the lifting and handling of goods, commonly used lifting mechanisms include hooks, suction cups, etc. [0003] In many extreme environments, such as the high-temperature environment of the iron and steel smelting site, the operation of the crane is not suitable for manual completion, and the use of unmanned vehicles can better solve this problem, but because it is an unmanned site, the rotation of the lifting mechanism causes The entanglement of the steel wire rope cannot be detected in time, which will cause certain safety hazards.
