Abstract
The utility model relates to a suspension mechanism, in particular to a hydraulic suspension mechanism for a large-scale powered flat-bed carrier. The suspension mechanism adopts the technical schemethat the suspension mechanism applied to the large-scale powered flat-bed carrier comprises a balancing arm, a hydraulic cylinder and a suspension frame, wherein an upper top surface of the suspensionframe is connected with a lower flat surface of the flat-bed carrier via a slewing bearing, the lower end portion of the suspension frame is hinged with one end portion of the balancing arm, the cylinder body of the hydraulic cylinder is hinged with the upper end portion of the suspension frame via an upper joint bearing, a piston rod of the hydraulic cylinder is hinged with the middle portion ofthe balancing arm via a lower joint bearing, and the other end portion of the balancing arm is hinged with an axle of the flat-bed carrier.
Description
Technical field
The utility model relates to a kind of hitch, particularly a kind of hydraulic lift mechanism that is used for large-sized power flat bed transport vehicle.
Background technology
The large-sized power flat bed transport capacity that transports out can reach several kilotons even higher tonnage, is widely used in heavy constructions such as shipbuilding yard, steelworks, electric power, petrochemical industry, can also apply to the transportation of case beam, uses as beam transportation vehicle.Because the load-carrying of this large-sized power flat bed transport vehicle is big, axis is many, the problem of some vehicle bridge overload appears easily.
At patent announcement is in the Chinese patent " independent steering suspension of large-sized power flat bed transport vehicle " of CN1850536, a kind of independent steering suspension has been described, it is made up of bracket flange, flange, hanger bracket, hydraulic actuating cylinder, equilibrium arm and wheel axis body, in this patent, flange is connected on the disk of bracket flange base plate face, the middle part of equilibrium arm is connected in the rotating shaft of flat bed transport vehicle, one end and the hanger bracket of equilibrium arm are hinged, the other end of equilibrium arm and the piston rod of hydraulic actuating cylinder are hinged, and the upper end and the hanger bracket of hydraulic actuating cylinder are hinged.Adopt this structure, the ability of vehicle adaptation uneven road surface is relatively poor, the road surface, " people " word slope that uneven road surface that impassabitity convex-concave degree is bigger and angle are bigger, and the guiding wearing and tearing of hydraulic actuating cylinder are big, and service life is short.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hydraulic lift mechanism with better modulability for large-sized power flat bed transport vehicle.
For solving above technical matters, the technical scheme that the utility model is taked is: a kind of hydraulic lift mechanism, this hitch is used for large-sized power flat bed transport vehicle, it comprises equilibrium arm, hydraulic actuating cylinder, hanger bracket, the last end face of described hanger bracket is connected with the lower plane of flat bed transport vehicle by pivoting support, one end of the bottom of described hanger bracket and described equilibrium arm is hinged, the cylinder body of described hydraulic actuating cylinder is hinged by the upper end of upper joint bearing and described hanger bracket, the piston rod of described hydraulic actuating cylinder is hinged by the middle part of hypozygal bearing and described equilibrium arm, and the other end of described equilibrium arm and the vehicle bridge of flat bed transport vehicle are hinged.
Preferably, offer first through hole on the described upper joint bearing, the upper end of described hanger bracket is provided with first hinged-support, is interspersed with first bearing pin in described first hinged-support and described first through hole.
Preferably, offer second through hole on the described hypozygal bearing, described equilibrium arm middle part is provided with second hinged-support, is interspersed with second bearing pin in described second hinged-support and described second through hole.
Because the enforcement of above technical scheme, the utility model compared with prior art, have following advantage: hydraulic actuating cylinder is connected the top of hanger bracket, the piston rod of hydraulic actuating cylinder is connected the middle part of equilibrium arm, vehicle bridge is connected the other end of equilibrium arm, this structure can make less oil cylinder stroke realize bigger lifting platform stroke, makes it that effect of amplifying the oil cylinder adjustment amount be arranged, and makes vehicle can adapt to the bigger road surface of convex-concave amplitude and by " people " word slope of wide-angle more; And hydraulic actuating cylinder vertically is provided with, and reduces the guiding wearing and tearing of oil cylinder, prolongs oil cylinder service life.
