Protective Shield for Concrete Hose Joints

摘要

A protective shield device is mounted on the joint between connected concrete hoses to protect the joint connecting one concrete hose to another from accidentally catching on an obstruction on the surface over which the concrete hose joint is moved during operation and disconnecting the two concrete hoses. The protective shield device is formed by two hollow shells that are hinged on one side and connected by friction closure members to surround and encapsulate the concrete hose joint. The assembled protective shield device is preferably in the shape of an ovoid with a larger central portion to accommodate the joint structure, and narrower end portions to provide no protruding structure that will catch any underlying obstructions that could cause the enclosed joint latch to be exposed. The protective shield device can be opened by forcing the two shell members apart, or by using a mechanically disengagable latch.

主权项

1. A protective shield device for encapsulating a joint mechanism connecting two concrete hose segments, comprising:
first and second members carrying latching members that can be aligned and engaged to secure one member to the other member, each respective member including a central portion defining a first diameter when the first and second members are secured together, each central portion including a pair of internal arcuate supports having a central passageway formed therein and establishing a central hole when said first and second members are secured together, each member further including a pair of frusto-conical portions integrally formed with said central portion, said frusto-conical portions extending from said central portion on opposing sides thereof to terminate at respective end portions defining an end opening, said end openings being aligned with said central hole through said arcuate supports for the passage of said concrete hose segments.
