Abstract
The utility model provides a multilevel hydraulic pressure cylinder of self-discharging vehicle to solve the problem that the multilevel hydraulic pressure cylinder of the prior vehicle has poor economical efficiency and stability. The cylinder comprises a back end cover, a piston rod and at least two levels of cylinder barrels and is characterized in that the back end cover is detachable; one inner hole on the back end of the first level of cylinder barrel of the hydraulic pressure cylinder is provided with a limit groove and the back end cover is connected and fastened with a positioning locking film arranged in the limit groove. The multilevel hydraulic pressure cylinder of self-discharging vehicle has the advantage that as the back end cover is detachable, the assembling, maintenance and detachment of the utility model becomes very convenient and economical efficiency and stability is improved, with good fabricability.
Description
Technical field: the utility model relates to the multistage hydraulic cylinder of dump truck.
Background technique: the dump truck multistage hydraulic cylinder of Shi Yonging in the market, oil hydraulic cylinder bottom shutoff is adopted welding or is used flange thread connecting mode, Economy and poor stability.
Summary of the invention: the utility model is for the multistage hydraulic cylinder Economy that solves existing dump truck, the problem of poor stability, a kind of multistage hydraulic cylinder of dump truck is proposed, comprise rear end cover, piston rod, two-stage cylinder barrel at least, it is characterized in that: described rear end cover is a detachability; Endoporus has a restraining groove in described oil hydraulic cylinder first order cylinder barrel rear end, and described rear end cover is connected tightly with the location locking plate that is installed in described restraining groove to be pluged with molten metal.The advantage of the multistage hydraulic cylinder of this dump truck is: because the detachability of rear end cover, make assembling, maintenance, dismounting very convenient, and processability is good, Economy and stability are improved.
Description of drawings: Fig. 1, the multistage hydraulic cylinder structural representation of the utility model dump truck.
Embodiment: the multistage hydraulic cylinder of this dump truck, comprise rear end cover, piston rod, two-stage cylinder barrel at least, as shown in Figure 1 be the level Four oil hydraulic cylinder, wherein a groove 5 is arranged at first order cylinder barrel 8 rear end endoporus, be used to install rear end cover location locking plate 2, after cylinder barrels 9,10,11 at different levels, piston rod 12 are packed first order cylinder barrel 8 successively into, again rear end cover 1 packed in the first order cylinder barrel 8, then locking plate 2 is installed in the groove, and locking plate 2 is connected with rear end cover 1 with screw 3,4.Owing to increased restraining groove at oil hydraulic cylinder first order cylinder barrel rear end endoporus, and tightly plug with molten metal with bolted mode by the locking plate and the rear end cover that are installed in the groove, it is dismountable to make rear end cover become, dismantle very convenient, thereby improved assembling, maintainability and processability greatly, Economy and stability are improved simultaneously.
