Abstract
The utility model relates to a rotatable supporting device of a lorry-mounted crane boom hydraulic cylinder, which belongs to hydraulic cylinder auxiliary devices and is characterized in that the left end section of a connecting bar is provided with a connecting plate through a left bearing, that is, the left bearing is installed between the connecting plate and the left end section of the connecting bar, a step hole is positioned on the connecting plate, the left bearing is arranged in the step hole, the position of the outer steel ring of the left bearing is fixed through a hole and an elastic retainer ring, moreover, the left end section of the connecting bar, which is provided with a step, is installed in the inner steel ring of the left bearing and fixed through a shaft and an elastic retainer ring to form relative rotation between the connecting plate and the connecting bar, an installation hole is positioned on the connecting plate for a bolt to penetrate through to lead a hydraulic cylinder barrel to be fixedly installed, the left end of a hydraulic cylinder piston rod is fixed on a boom by a hydraulic cylinder pin, thus, when the supporting device of the hydraulic cylinder slides freely, the eccentric rotation cause by the rotation of the hydraulic cylinder barrel and produced errors can be compensated through the relative rotation of the left bearing, the damage of the hydraulic cylinder and oil pipes is effectively reduced, and the normal operation of the lorry-mounted boom hydraulic cylinder is guaranteed.
Description
Technical field
The utility model belongs to the oil cylinder auxiliary device, especially relates to a kind of support device of lorry-mounted crane arm support oil cylinder.
Background technique
The piston end of the arm support oil cylinder of lorry-mounted crane is fixed, and the cylinder tube end can be free to slide, at present, the arm support oil cylinder of lorry-mounted crane all realizes being free to slide by sliding support is installed, but this sliding support can only make oil cylinder slide along the flexible direction of jib, and when real work, cylinder tube must have a little rotation with respect to the piston fixed end on the one hand, thereby be with sliding support to rotate together, just causing the pulley of support device on original track, not slide; Must there be error in the piston fixed end of arm support oil cylinder in processing with in installing on the other hand; the relative jib of oil cylinder can not be on the same parallel lines; can make pulley deflection again; both of these case all is harmful to the structure of oil cylinder and the bearing in the sliding support; in most of the cases can have influence on the oil pipe on the oil cylinder; cause leakage of oil and booster through regular meeting's oil connection of grinding away, serious even cause the lorry-mounted crane cisco unity malfunction.
Summary of the invention
The purpose of this utility model provides the rotatable support device of a kind of lorry-mounted crane arm support oil cylinder, make arm support oil cylinder when being free to slide, possess function in relative rotation again, not only simple in structure, easy for installation, saving of work and time, and make whole hydraulic system more perfect, and reduce the wearing and tearing of oil pipe, further guarantee the proper functioning of lorry-mounted crane.
The purpose of this utility model is achieved like this: a kind of lorry-mounted crane arm support oil cylinder turns support device, comprise connecting plate, connecting rod, fixing frame, stationary axle and pulley, connecting rod is welded on the epimere of the left surface of perpendicular cross section of the putting fixing frame that is rectangle and is 90 ° of angles with it, between connecting rod and fixing frame, go back the circumference uniform distribution weldering and establish the reinforcement gusset, on fixing frame, offer sagittal axis hole and the corresponding respectively stationary axle up and down that in each axis hole, installs on the section of lower end respectively symmetrically, corresponding to the position in the middle of the stationary axle up and down, at fixing frame with offer positioning hole respectively on the stationary axle up and down and the corresponding respectively elastic cylindrical pin of installing in each positioning hole, stationary axle is fixedly mounted on the fixing frame respectively up and down, on the front end and back end of stationary axle up and down, use the Bearing Installation pulley respectively, like this, each pulley bolster fixing frame, connecting rod and the cylinder tube that is installed on the connecting rod left end connecting plate are done left and right sides slippage on jib; It is characterized in that: connecting plate is installed at the left end Duan Shangyong of connecting rod left bearing, promptly between the left end section of connecting plate and connecting rod, left bearing is installed, on connecting plate, offer step hole, left bearing is installed in this step hole, its outer rim is located with circlip for hole, the left end section with the level of connecting rod is installed in the interior steel ring of left bearing and and fixes with circlip for shaft, make to form between connecting plate and the connecting rod and relatively rotate, on connecting plate, offer mounting hole and install bolt installation cylinder tube, the left end of oil cylinder piston bar is fixed on the jib by the oil cylinder pin, like this, when the oil cylinder support device is free to slide, can remedy the rotation and the manufacturing of cylinder tube by relatively rotating of left bearing, the deflection that alignment error produced, reduce the damage of oil cylinder and oil pipe effectively, guarantee the proper functioning of lorry-mounted crane arm support oil cylinder.
The lorry-mounted crane arm support oil cylinder that the utility model proposed turns support device, and is rational in infrastructure, safe and reliable, reduces the damage of oil cylinder and oil pipe effectively, guarantees the proper functioning of lorry-mounted crane arm support oil cylinder.
Now in conjunction with the accompanying drawings and embodiments the rotatable support device of the lorry-mounted crane arm support oil cylinder that the utility model proposed is further described.
