Description

Hydraulic lifting and locking equipment for cab
Technical Field
The invention relates to the field of machine manufacturing, in particular to a hydraulic lifting and locking device for a cab.
Background
The hydraulic lifting element is a hydraulic actuating element with excellent performance and is widely applied to the fields of military affairs, aerospace, medical treatment and the like. The cab of the medium and heavy trucks is of a flat-head cab structure, and the engine cabin is arranged below the cab. When parts in an engine compartment need to be overhauled, a cab needs to be turned forwards by a certain angle. Because the cab of the medium and heavy trucks is too heavy, the cab cannot be turned over by manpower, and the cab must be turned over by the aid of a turning device.
At present, a cab turnover device of a medium-heavy truck mainly adopts hydraulic lifting turnover, a hydraulic oil circuit of the cab turnover device mainly adopts a single-pipeline system, and when the cab is lifted, hydraulic oil is pressed in from an oil nozzle at the bottom of an oil cylinder, so that a piston rod extends out of the cylinder under the action of pressure, and the cab is lifted to a certain angle; when the cab needs to descend, the reversing valve is rotated, and the cab automatically falls under the action of the dead weight of the cab. The lifting device has the advantages of simple structure and convenient operation, and has the defects that the descending speed of the cab is not easy to control, the cab falls completely by the dead weight of the cab, when an oil pipe bursts accidentally or the reversing valve is changed unintentionally, the cab falls automatically, the safety of maintenance personnel below the cab cannot be effectively guaranteed, and accidental safety accidents can easily occur.
At present, the key process that the locking stability of a cab is insufficient is sometimes completed by manual operation, and the method is low in efficiency, high in time consumption and high in cost. The cab of the medium and heavy trucks is of a flat-head cab structure, the engine cabin is arranged below the cab, and when parts such as an engine and the like need to be overhauled, locking equipment needs to be used for firmly locking the cab. In the real production life, because the cab of the medium and heavy truck is heavier, the sliding hook and other great potential safety hazards exist only by means of manual mechanical locking.
