Description
Technical Field
The utility model relates to a detachable connection structure of a piston rod and a hanging head of a large hydraulic cylinder. The hydraulic and hydroelectric engineering system is suitable for hydraulic and hydroelectric engineering.
Background
In the comprehensive water environment renovation and navigation gate and dam engineering, a flap gate is often adopted to raise, regulate and control the inland water level so as to improve the surrounding ecological environment condition. The flap gate is generally operated by adopting a hydraulic hoist, the hydraulic hoist is arranged in gate piers at two sides of an orifice, a ship crane or other modes are adopted to hoist a hydraulic cylinder when overhaul or replacement is needed, daily minor repair, replacement of a sealing ring and the like are completed in the gate piers, but the sealing ring is replaced only by detaching a hanging head limited by the size of the gate piers, the hanging head is in threaded connection with a piston rod, the hanging head size and the dead weight of a large hydraulic cylinder are very large, and the large hydraulic cylinder can not be detached basically, so that the maintenance and the service life of the hydraulic cylinder are influenced.
Disclosure of Invention
The utility model aims to solve the technical problems that: aiming at the problems, a detachable connection structure of a piston rod and a hanging head of a large hydraulic cylinder is provided.
The technical scheme adopted by the utility model is as follows: a detachable connection structure of a large-scale hydraulic cylinder piston rod and a hanging head is characterized in that: the connecting sleeve is used for connecting the piston rod and the hanging head, wherein connecting protrusions are respectively arranged on the side walls of the connecting ends of the piston rod and the hanging head, and connecting grooves matched with the connecting protrusions on the piston rod and the hanging head are formed in the inner wall of the connecting sleeve;
the connecting sleeve is formed by splicing the upper half-tiles and the lower half-tiles which are connected in a semicircular mode in cross section, the sleeve is sleeved outside the connecting sleeve, and the sleeve is fixedly connected with the connecting sleeve through screws.
The connecting protrusions on the piston rod are a plurality of annular convex rings of the piston rod; the connecting protrusions on the hanging heads are a plurality of hanging head annular convex rings.
The beneficial effects of the utility model are as follows: according to the utility model, the connecting groove in the connecting sleeve is matched with the connecting protrusion on the piston rod and the hanging head, so that the connecting sleeve is fixedly connected with the piston rod and the hanging head; the sleeve is sleeved on the connecting sleeve, so that the connecting sleeve formed by splicing the two connecting half tiles is stable and reliable in structure.

Detailed Description
As shown in fig. 1 and 2, the present embodiment is a detachable connection structure of a piston rod and a lifting head of a large hydraulic cylinder, which comprises a connecting sleeve for connecting the piston rod and the lifting head, one end of the connecting sleeve is sleeved at the connecting end of the piston rod, the other end of the connecting sleeve is sleeved at the connecting end of the lifting head, and the connecting sleeve is sleeved with a sleeve, and the sleeve is fixedly connected with the connecting sleeve through a screw.
In the embodiment, connecting bulges are respectively arranged on the side walls of the connecting ends of the piston rod and the hanging head, wherein the connecting bulges on the piston rod are a plurality of annular convex rings of the piston rod; the connecting protrusions on the hanging heads are a plurality of hanging head annular convex rings.
In this embodiment, a connection groove adapted to a plurality of annular convex rings of the piston rod and a connection groove adapted to a plurality of annular convex rings of the hanging head are formed on the inner wall of the connecting sleeve.
In the embodiment, the connecting sleeve is formed by splicing the upper half-tiles and the lower half-tiles, the cross sections of which are semicircular, and the two half-tiles are fixedly connected by sleeve matched screws sleeved outside the connecting sleeve.
In the embodiment, a plurality of screw mounting holes are formed in the sleeve, and the screw mounting holes are internally divided into a large-diameter section with the diameter larger than that of the screw cap and a small-diameter section with the diameter matched with the screw main body from outside to inside; screw holes with diameters matched with the screw main body are formed on the outer side surface of the connecting half tile.
In this example, the screw passes through the washer and the screw mounting hole in the large diameter section of the screw mounting hole on the sleeve and then is connected with the screw hole on the connecting half tile.
When the detachable connecting structure is detached in the embodiment, the screw is screwed out, the sleeve is removed, and the upper connecting half tile and the lower connecting half tile are taken down, so that the hanging head and the piston rod can be separated.
The above embodiments are only for illustrating the inventive concept of the present utility model and not for limiting the protection of the claims of the present utility model, and all the insubstantial modifications of the present utility model using the concept shall fall within the protection scope of the present utility model.
