Description
Technical Field
The utility model relates to a fixed technical field of valve specifically is a valve fixed knot constructs.
Background
The crushing pipeline of the excavator is usually selected and modified, main hydraulic elements such as an overflow valve for adjusting crushing pressure need to be fixed on the pipeline of a working device, the overflow valve is usually a purchased part and has no excessive selection, the common overflow valve has an irregular shape and does not provide any installation connection point, and an oil port also needs to be installed and fixed for use; meanwhile, the overflow valve is provided with oil ports in each direction, a pipeline and a joint need to be opened, any other processing surface outside the oil ports is not provided, and the rest surfaces are casting blank surfaces, so that the size cannot be ensured, and the installation and the fixation are difficult; meanwhile, when the excavator works, vibration impact is large, the motion of the large arm is inconsistent with that of the frame, and pipelines are easy to distort, so that valve fixing failure or cracking and oil leakage are easy to cause.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problems that when the excavator works, vibration impact is large, and valve fixing failure or cracking and oil leakage are easily caused are solved.
The utility model provides a valve fixing structure, which comprises a base, a first supporting plate, a second supporting plate, a first pressing plate, a second pressing plate, a connecting plate and a valve; the first supporting plate and the second supporting plate are arranged at two ends of the base, the first pressing plate is arranged at the upper end of the first supporting plate, and the second pressing plate is arranged at the upper end of the second supporting plate; the first pressing plate and the second pressing plate are identical in structure and are arranged in a centrosymmetric mode, and the first pressing plate and the second pressing plate are fixedly connected through the connecting plate; the first pressing plate comprises a flat plate and a convex strip group; the convex strip group comprises a first convex strip and a second convex strip, and the first convex strip and the second convex strip are vertically fixed on the flat plate; the convex strips on the first pressing plate and the second pressing plate are combined to form a square structure; the lower end of the valve is fixedly connected with the upper end of the base, and the upper end of the valve is positioned in the square structure; the upper and lower ends of the valve are clamped by the base, the first pressure plate and the second pressure plate, so that the upper and lower ends of the valve are limited in freedom; the left end, the right end, the front end and the rear end of the valve are clamped by the square structure, so that the degrees of freedom of the left end, the right end, the front end and the rear end of the valve are limited; the valve is in a static state relative to the pipeline, and even if the valve fails, the adverse effects of cracking and oil leakage cannot be caused.
Further, the connecting plate is provided with a round hole and a waist-shaped hole, and because the valve is irregular in shape and does not provide any other processing surface outside the oil port, the rest surfaces are casting blank surfaces, the size cannot be guaranteed, the first pressing plate and the second pressing plate are opposite to the position which needs to be adjusted when the valve is compressed, and the waist-shaped hole provides a space for the adjustment of the first pressing plate and the second pressing plate.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model provides a valve fixing structure, which comprises a base 1, a first supporting plate 2, a second supporting plate 3, a first pressing plate 4, a second pressing plate 5, a connecting plate 6 and a valve 7; the first supporting plate 2 and the second supporting plate 3 are identical in structure and provided with 2 symmetrical through holes, the first supporting plate and the second supporting plate are mounted at two ends of the base 1, the base 1 is provided with 4 symmetrical small holes, the small holes are concentric with the through holes, the first supporting plate 3 and the second supporting plate 4 are used for supporting bolt tightening force, the pressing plate 2 is prevented from deforming due to bolt tightening torque, and the effect of a spacer is achieved; the first pressing plate 4 and the second pressing plate 5 are identical in structure and are respectively provided with a pair of mounting holes, the first pressing plate 4 is mounted at the upper end of the first supporting plate 2, the second pressing plate 5 is mounted at the upper end of the second supporting plate 3, and the mounting holes are concentric with the through holes; the valve is arranged above the base 1, between the first support plate 2 and the second support plate 3 and below the first pressing plate 4 and the second pressing plate 5; the first pressing plate 4 and the second pressing plate 5 are centrosymmetric and are fixedly connected with the connecting plate 6; the connecting plate is equipped with a round hole and a waist shape hole, because the valve shape is irregular and do not provide any other machined surface outside the hydraulic fluid port, the rest face all is the casting blank face, and the size can not be guaranteed, first clamp plate with the second clamp plate is right the valve needs the adjusting position when compressing tightly, waist shape hole gives first clamp plate with the regulation of second clamp plate provides the space.
As shown in fig. 2, the first pressing plate 4 includes a flat plate 13 and a convex strip group, the convex strip group includes a first convex strip 11 and a second convex strip 12, the first convex strip 11 and the second convex strip 12 are vertically welded on the flat plate 13, and the convex strips on the first pressing plate 4 and the second pressing plate 5 are combined to form a square structure; the base 1, the first pressing plate 4 and the second pressing plate 5 clamp the upper end and the lower end of the valve 7, so that the degree of freedom of the upper end and the lower end of the valve 7 is limited, and the square structure clamps the left end, the right end, the front end and the rear end of the valve 7, so that the degree of freedom of the left end, the right end, the front end and the rear end of the valve 7 is limited; the valve 7 is in a static state relative to the pipeline, and even if the valve fails, the adverse effects of cracking and oil leakage cannot be caused.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
