Abstract
The invention discloses a kind of eversion type protecting sleeve for the protection of the ductile iron pipe mouth of pipe, relate to technical field of nodular cast iron pipe orifice protection.This protecting sleeve material is soft rubber, and this protecting sleeve is the cylinder-like structure overlapped that can turn up, and the external diameter of described protecting sleeve equals the spout diameter of ductile iron pipe.The peculiar elastic force of rubber is utilized to make protecting sleeve firmly be wrapped in the mouth of pipe place of cast tube; its outside face contacted at protecting sleeve and the mouth of pipe is provided with gully; increase friction force; protecting sleeve is made to be not easy to come off when transporting and hoisting; when ensureing that cast tube and cast tube are stacked, contact surface has protecting sleeve protect, produces good buffer action when ductile iron pipe can be made like this to collide in lifting with in the middle of transporting.
Description
Technical field
The present invention relates to technical field of nodular cast iron pipe orifice protection.
Background technology
Present stage, China's Urbanization Construction deepened continuously development, in state key project financing and Urban Buried Pipeline Network, ductile iron pipe is because existing good resistance to compression and durability are by a large amount of application, but because construction site and manufacturer are often distant, train can only be passed through, automobile, the vehicle transports such as steamer, like this have bad luck and deposit in process have many dusts or a junk drop in cast tube, moreover, and in transport and hoisting process, when we use anticorrosion coating inside the hook mouth of pipe of crane and cement layer, due to the deadweight problem of cast tube itself, easy generation hooks bad situation, simultaneously be also easy to collide with in transportation between the mouth of pipe outside cast tube and cast tube, cast tube surface anticorrosion coating is damaged, affect the presentation quality of product, there is quality objection, cause shorten service life, and there is no the device of the actv. protection nodular cast iron pipe mouth of pipe now.
Therefore be badly in need of now a kind of can the device protected of the mouth of pipe of actv. to ductile iron pipe.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can protect the eversion type protecting sleeve of its mouth of pipe by actv. in ductile iron pipe transport and hoisting process.
For solving the problem; the technical scheme that the present invention takes is: a kind of eversion type protecting sleeve for the protection of the ductile iron pipe mouth of pipe; this protecting sleeve material is soft rubber, and this protecting sleeve is the cylinder-like structure overlapped that can turn up, and the external diameter of described protecting sleeve equals the spout diameter of ductile iron pipe.
The outside face of preferred described protecting sleeve is evenly distributed with the gully consistent with protecting sleeve axis direction, direction or projection.
Preferred described gully or protruding undulate.
The beneficial effect adopting technique scheme to produce is: the design of this device have employed the elastomeric material with certain mechanical strength, be made into cylindric protecting sleeve, the peculiar elastic force of rubber is utilized to make protecting sleeve firmly be wrapped in the mouth of pipe place of cast tube, its outside face contacted at protecting sleeve and the mouth of pipe is provided with gully, increase friction force, protecting sleeve is made to be not easy to come off when transporting and hoisting, ensure cast tube and cast tube stacked time contact surface have protecting sleeve protection, such ductile iron pipe that can make produces good buffer action in lifting and transport when colliding, prevent the mouth of pipe from seeking bad or hurting sb.'s feelings.

The structural representation of Fig. 2 using state of the present invention.
Wherein, 1, ductile iron pipe, 2, protecting sleeve, 3, gully or projection.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation: a kind of eversion type protecting sleeve for the protection of the ductile iron pipe mouth of pipe as depicted in figs. 1 and 2; this protecting sleeve 2 material is soft rubber; this protecting sleeve 2 is the cylinder-like structure overlapped that can turn up, and the external diameter of protecting sleeve 2 equals the spout diameter of ductile iron pipe 1.The gully consistent with protecting sleeve 2 axis direction, direction or protruding 3 are evenly distributed with, gully or protruding 3 undulates at the outside face of protecting sleeve 2.The mouth of pipe of ductile iron pipe 1 is divided into bellmouth and socket, bellmouth is greater than socket, so the external diameter size of this protecting sleeve 2 also can be different because of the pipe diameter size of the mouth of pipe, it is to well be enclosed within above bellmouth and socket that this protecting sleeve 2 is set as cylindrical shape, varying in size of protecting sleeve 2, there is the protecting sleeve 2 of the various calibers matched with the caliber of ductile iron pipe 1, we are using in the bellmouth or socket first its half being inserted into ductile iron pipe 1 when this protecting sleeve 2, then by be exposed at tube outside second half to turning up, second half is enclosed within outside ductile iron pipe 1, owing to being provided with gully or protruding 3 on the whole outside face of protecting sleeve 2, which increase the friction between protecting sleeve 2 and ductile iron pipe 1, make more difficult drop-off.
The beneficial effect adopting technique scheme to produce is: the design of this device have employed the elastomeric material with certain mechanical strength, be made into cylindric protecting sleeve, the peculiar elastic force of rubber is utilized to make protecting sleeve firmly be wrapped in the mouth of pipe place of cast tube, its outside face contacted at protecting sleeve and the mouth of pipe is provided with gully, increase friction force, protecting sleeve is made to be not easy to come off when transporting and hoisting, ensure cast tube and cast tube stacked time contact surface have protecting sleeve protection, such ductile iron pipe that can make produces good buffer action in lifting and transport when colliding, prevent the mouth of pipe from seeking bad or hurting sb.'s feelings.
