A folding arm crane and its control system and a garbage truck with the folding arm crane

Abstract

The invention provides a folding-arm crane and its control system and a garbage truck with the folding-arm crane. The folding-arm crane includes: a machine base, which is welded with thin plates to form a bow-shaped box; The folding arm crane rotates clockwise or counterclockwise; the turntable is installed on the support of the turntable to provide the basis for connecting the support of the turntable and the boom. The turntable is welded by thin plates, and the hinge point of the luffing cylinder of the boom is located above the front of the turntable , the boom hinge point is located at the front and bottom of the turntable; the tail end of the boom is hinged on the boom hinge point of the turntable, and can rotate along the boom hinge axis on the turntable under the push and pull of the boom luffing cylinder; the boom luffing Oil cylinder, the tail end is hinged on the hinge point of the large arm luffing cylinder of the turntable, the head end is hinged on the large arm; the folding arm and the folding arm luffing cylinder, the folding arm is hinged on the folding arm hinge point on the large arm, Under the push and pull of the knuckle luffing oil cylinder, it can rotate along the knuckle hinge axis on the boom.

Description

technical field [0001] The invention belongs to the field of knuckle-arm crane and its control technology, and in particular relates to a knuckle-arm crane and its control system and a garbage truck with the knuckle-arm crane. Background technique [0002] With the process of urbanization, the urban area continues to expand, the scale of urban-rural integration is becoming more and more obvious, and the problem of urban domestic waste is becoming more and more serious. How to effectively and quickly deal with urban domestic waste has gradually become a major problem in urban management. The size of the garbage bins in the city is determined according to the population living in the area. In some areas where the urban construction is not yet complete, the construction of garbage stations is not fully equipped. It cannot be implemented if it does not meet the construction standards, and the cost of manual collection is high. [0003] Garbage trucks are one of the important me...

Problems solved by technology

[0006] 2) For traditional truck-mounted cranes, the main oil cylinder is installed on the side of the turntable, which requires a higher height of the turntable. For the traditional crane installed on the chassis of the car, the traditional structure will not lead to super high vehicle height, and the use is good, but for When installed on the top of a hoisting garbage truck, the turntable structure causes the vehicle to be super high and the hoisting is unstable, so it is not suitable for installation on the top of a hoisting garbage truck;
