Abstract

The utility model relates to a bolt type centrifugal roll end cover, which comprises an end cover body, wherein the upper surface of the end cover body is provided with a screw hole, and both ends are provided with blind holes; and a pin shaft is inserted in the blind hole. The advantages are that: the whole structure is simple, blind holes are formed in the two ends of the end cover body, the roller end cover is turned over under the stress of the pin shaft, the roller end cover is hoisted through the bolts connected to the end cover body, and the service life of the end cover is prolonged. The bolt type hoisting structure is convenient for field workers to operate.

Description

Bolt type centrifugal roller end cover

Technical Field

The utility model belongs to a centrifugal casting end cover especially relates to a bolt formula centrifugation roll end cover.

Background

At present, the centrifugal casting roller end cover in China generally adopts an integral casting production mode, and in order to be convenient to hoist, hanging handles are generally cast at two ends of the end cover. The "hanging handle" position forms a stress concentration point, see fig. 1, and the end cover is usually scrapped due to cracks generated at the "hanging handle" position in the using process.

Disclosure of Invention

For overcoming the not enough of prior art, the utility model aims at providing a bolt formula centrifugation roll end cover reduces end cover crackle tendency, improves end cover life.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

a plug pin type centrifugal roller end cover comprises an end cover body, wherein a screw hole is formed in the upper surface of the end cover body, and blind holes are formed in two ends of the end cover body; and a pin shaft is inserted in the blind hole.

The screw holes are uniformly distributed on the upper surface of the end cover body in the radial direction.

And the screw hole is internally threaded with a bolt.

The blind holes are symmetrically arranged at two ends of the end cover.

Compared with the prior art, the beneficial effects of the utility model are that:

bolt formula centrifugation roll end cover overall structure is simple, through set up the blind hole at end cover body both ends to realize the roll end cover upset through round pin axle atress, realize the hoist and mount of roll end cover through the bolt of connecting at the end cover body, cancelled centrifugal casting roll end cover stress concentration point, improved the life of end cover. The bolt type hoisting structure is convenient for field workers to operate.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

Referring to fig. 2-3, the plug pin type centrifugal roll end cover comprises an end cover body 2, wherein the end cover body 2 is formed by adopting an end cover integral casting method, a screw hole 4 is formed in the upper surface of the end cover body 2, and blind holes 3 are formed in two ends of the end cover body; and a pin shaft is inserted in the blind hole 3, so that the end cover can be conveniently turned by an operator.

Wherein, the 4 radial equipartitions of screw are at end cover body 2 upper surfaces to avoid arranging in same position with blind hole 3, 4 threaded connection in screw has the bolt, avoids stress concentration point's production, and the construction bolt can conveniently be to roll end cover handling, simultaneously, the convenient drawing die of casting shaping back. The blind holes 3 are symmetrically arranged at two ends of the end cover.

In practical production, the end cover body 2 with the outer diameter of 1000mm is cast, and the two ends of the end cover body 2 are drilled

The hole, the upset of end cover body 2 can be realized to the cooperation round pin axle. 4M 18X 25's screw hole 4 is bored at the end cover top, and stagger the position of blind hole 3, and the construction bolt makes things convenient for the operation personnel to hoist and mount end cover body 2 more.

Claims
