Vertical cylinder base plate of truck crane

Abstract

The invention discloses a vertical cylinder base plate of a truck crane. The vertical cylinder base plate comprises a base and a support, wherein the support is fixed to the base through a plurality of screws; the base comprises a pedestal, a gasket and bushings; the pedestal, which is manufactured through nonmetal materials, is that the bottom part is in a shape of a cylinder, the middle part is in a shape of a cone, the top part is a cylinder boss which upwards extends, and the top surface is provided with a step type circular groove and a plurality of blind holes which are formed around the circular groove; the gasket is manufactured through metal materials and has a disc shaped structure provided with a boss, and a spherical groove is formed in the center of the top surface of the gasket; the bushings are manufactured through metal materials and have disc shaped structures of which the bottom parts are provided with bosses, and inner thread holes are formed in the centers of the bushings; the gasket and the bushings are correspondingly embedded into the circular groove and the blind holes in the pedestal in a sleeving manner; the bracket is manufactured through metal materials and comprises two arc-shaped side plates which are parallel to each other, and U-shaped bottom plates which are positioned at the bottom parts of the two arc-shaped side plates; a plurality of through holes of which the quantity and positions are corresponding to those of the blind holes are formed in the U-shaped bottom plates. The vertical cylinder base plate of the truck crane is simple in structure, light in weight, liable to dismount and mount, and convenient to carry.

Description

technical field [0001] The invention relates to a backing plate of a truck crane, in particular to a backing plate of a vertical oil cylinder of a truck crane. Background technique [0002] At present, the backing plate of the vertical oil cylinder of the truck crane is generally welded by metal materials, and the base of the backing plate and the bracket are integrally welded. For the medium and large tonnage truck cranes, in order to meet the load-bearing requirements, the structural size of the vertical oil cylinder backing plate is generally large. , the weight also increases, generally above 30kg. Sometimes due to structural constraints, the outer edge of the backing plate exceeds the width of the vehicle after installation, and it must be ensured not to exceed the width when the truck crane is in the driving state, which results in the need for frequent disassembly and transportation, or the use of a pull-out structure to move Vertical cylinder backing plate. For med...

AI Technical Summary

Problems solved by technology

Sometimes due to structural constraints, the outer edge of the backing plate exceeds the width of the vehicle after installation, and it must be ensured not to exceed the width when the truck crane is in the driving state, which results in the need for frequent disassembly and transportation, or the use of a pull-out structure to move Vertical cylinder backing plate

For medium and large tonnage truck cranes, the weight of the vertical cylinder backing plate is heavy, and it is difficult for adults to disassemble and carry it. Even the pull-out structure is difficult to move the backing plate, which is prone to bruising and crushing
