Abstract
The utility model discloses a piston rod structure of a multilevel lifting oil cylinder, which belongs to the technical field of a piston rod device of an oil cylinder. The piston rod structure of the multilevel lifting oil cylinder comprises a central oil pipe, a piston, a rod body, a rod head, a pipe plug, a check ring, an O-shaped ring and a pressing plate, wherein the central oil pipe is fixedly connected with the pipe plug, then is fixedly connected with the rod head, then is fixedly connected with the rod body, and then is fixedly connected with the pressing plate and the piston provided with the check ring and the O-shaped ring. The piston rod structure has the beneficial effects that the central oil pipe and the rod head are connected together through the pipe plug, the rod head and the rod body are welded together, and a piston rod and the piston are connected through a bolt; the weld joints of the structure are on the outside, the welding is convenient, and cleaning welding slag is easy; and the performance of the lifting cylinder is improved to some extent.
Description
Technical field
The utility model relates to a kind of oil cylinder piston lever arrangement, relates in particular to a kind of multistage elevating ram piston rod construction, belongs to oil cylinder piston lever arrangement technical field.
Background technique
At present, the center oil pipe of multistage elevating ram is directly to weld together with piston rod on the electric wheel quarry tipper, and piston rod and piston link together with bolt.Because the center oil pipe can not stretch out piston rod, welding is in the piston rod hole, and welding is not very convenient; Quality cannot say for sure card, and the thickness of center oil pipe is not again very big, and welding consumables is easy to get into the endoporus of center oil pipe; Welding slag is easy to clean not, influences the performance of elevating ram simultaneously.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model provides a kind of multistage elevating ram piston rod construction, makes the weld seam of weld all be located at the outside, convenient welding and clear up welding slag easily.
To achieve these goals; The technological scheme that the utility model adopts is: a kind of multistage elevating ram piston rod construction, comprise center oil pipe, piston, the body of rod and bar head, and also comprise pipe plug, back-up ring, O type circle and pressing plate; The center oil tube and tube is stifled to be fixedly connected; Be fixedly connected with the bar head again, be fixedly connected with the body of rod again, again with piston and the pressing plate of back-up ring with O type circle be housed be fixedly connected.
Further, the stifled welding of center oil tube and tube with the welding of bar head, is welded with the body of rod more again.
Further, be connected with bolt through packing ring between the center oil pipe that is fixed together, pipe plug, bar head and the body of rod and piston and the pressing plate.
The beneficial effect of the utility model is: utilize pipe plug that center oil pipe and bar head are coupled together, the bar head and the body of rod are welded together again, with bolt piston rod is connected with piston.This construction joint all outside, convenient welding and clear up welding slag has easily improved the performance of lifting cylinder to a certain extent.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, the body of rod, 2, the center oil pipe, 3, the bar head, 4, pipe plug, 5, back-up ring, 6, O type circle, 7, piston, 8, pressing plate, 9, packing ring, 10, bolt.
Embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 1; The utility model comprises center oil pipe 2, piston 7, the body of rod 1 and bar head 3; Also comprise pipe plug 4, back-up ring 5, O type circle 6 and pressing plate 8, center oil pipe 2 is fixedly connected with pipe plug 4, is fixedly connected with bar head 3 again; Be fixedly connected with the body of rod 1 again, be fixedly connected with piston 7 and pressing plate 8 that back-up ring 5 and O type circle 6 are housed again.Wherein, center oil pipe 2 and pipe plug 4 welding are again with 3 welding of bar head, again with the body of rod 1 welding; Be connected with bolt 10 through packing ring 9 between the center oil pipe 2 that is fixed together, pipe plug 4, bar head 3 and the body of rod 1 and piston 7 and the pressing plate 8.
Use pipe plug 4 that center oil pipe 2 and bar head 3 are coupled together earlier, again the bar head 3 and the body of rod 1 are welded together, with bolt 10 it is connected with piston 7 again.Make weld seam all outside, convenient welding and clear up welding slag has easily improved the performance of lifting cylinder to a certain extent.
