Abstract
The invention discloses a multi-stage lifting oil cylinder buffer mechanism which belongs to the technical field of engineering mechanical parts, and comprises an oil cylinder and a buffer valve rod; an installation groove is arranged at the bottom of the oil cylinder; an installation groove is arranged on the buffer valve rod; a steel wire retaining ring is also arranged; and the installation grooves at the bottom of the oil cylinder and on the buffer valve rod are connected through the steel wire retaining ring. The multi-stage lifting oil cylinder buffer mechanism has the beneficial effects that the connection is simple; the detachment is convenient, not only is the precision ensured but also the maintenance is improved.
Description
Technical field
The present invention relates to a kind of multistage elevating ram damping mechanism, belong to the engineering mechanical components technical field.
Background technique
At present, the trimmer valve mechanism of multistage elevating ram adopts the mode of buffering valve rod and cylinder bottom welding on the electric wheel quarry tipper, welding unavoidably can cause certain deformation, the postwelding welding slag is difficult for cleaning out, and the coaxality of very difficult assurance and piston, influenced the performance of oil cylinder to a certain extent, simultaneously can not dismounting, maintenance is inconvenient.
Summary of the invention
Problem at above-mentioned prior art exists the invention provides a kind of multistage elevating ram damping mechanism, and dismounting and maintenance are more convenient.
To achieve these goals, the technical solution used in the present invention is: a kind of multistage elevating ram damping mechanism, comprise oil cylinder, buffering valve rod, also comprise Steel Cable Baffle Ring, the oil cylinder bottom is provided with first mounting groove, the buffering valve rod is provided with second mounting groove, and first mounting groove of oil cylinder bottom and second mounting groove that cushions on the valve rod are connected by Steel Cable Baffle Ring.
The invention has the beneficial effects as follows: connect simply, convenient disassembly had both guaranteed that precision had also improved maintainability.
Description of drawings
Fig. 1 is the prior art schematic representation;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is an I portion enlarged diagram among Fig. 2.
Among the figure: 1, oil cylinder, 2, Steel Cable Baffle Ring, 3, the buffering valve rod.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figures 2 and 3: the present invention includes oil cylinder 1, buffering valve rod 3, also comprise Steel Cable Baffle Ring 2, oil cylinder 1 bottom is provided with first mounting groove, and buffering valve rod 3 is provided with second mounting groove, and first mounting groove of oil cylinder 1 bottom and second mounting groove that cushions on the valve rod 3 are connected by Steel Cable Baffle Ring 2.
The present invention at first is installed in Steel Cable Baffle Ring 2 second mounting groove of buffering valve rod 3 when mounted, will cushion first mounting groove that valve rod 3 is connected in oil cylinder 1 bottom again, realizes its connection.
