Abstract

The invention relates to the technical field of cranes, and discloses a winding rope anti-stall device used for a vehicle-mounted crane. The winding rope anti-stall device comprises a lifting arm anda rolling shaft, wherein the outer part of the lifting arm is fixedly connected to a fixed base; a slide rail I is fixedly connected outside the fixed base; a slide rod is movably connected inside theslide rail I; and the outer part of the slide rod is movably connected to a connecting rod. Under mutual action of the lifting arm, the rolling shaft, the fixed base, the slide rail I, the slide rod,the connecting rod, a pressure plate, a pressure block and a hydraulic rod, the rolling shaft will have stall rotation under motion of a winding rope if the winding rope is broken or the crane failswhile the vehicle-mounted crane lifts goods, so that a reduction brake plate is in contact with the winding rope under action of an induction structure, and the winding rope reduction effect can be realized under action of the reduction brake plate, and thus, unnecessary property loss caused by stall motion of the winding rope and the goods as well threat on safety of staff are avoided.

Description

technical field

[0001] The invention relates to the technical field of cranes, in particular to a cable stall prevention device for vehicle-mounted cranes. Background technique

[0002] Vehicle-mounted cranes generally refer to tire cranes, and the main feature of tire cranes is that they combine the driving cab and lifting control room into one, which overcomes the shortcomings of crawler cranes that cause damage to the road surface, and belong to material handling machinery. .

[0003] Vehicle-mounted cranes are generally equipped with extendable telescopic arms and cables for pulling goods. The cables generally need to go through the fixed pulley at the end of the telescopic arm away from the car body to achieve the purpose of lifting goods. However, the existing vehicle-mounted cranes lack a safety device, that is, when the vehicle-mounted crane breaks the cable or the crane fails in the process of lifting the cargo, the cargo will stall and descend and the cable will f...
