JPH07174273A - Universal joint for pipe - Google Patents

Abstract

PURPOSE:To eliminate the flapping a hose generated in association with gun shaking motion in the robotization of gun spray work of mortar or the like in building and civil engineering work by providing a joint with a male part, a female part and a cover respectively having spherical parts. CONSTITUTION:A male part 2 with the spherical inner surface slidably engaged with the spherical outer surface of a female part 1 is fitted into the female part 1 with the spherical outer surface, and the fit-in state of the female part 1 and male part 2 are held by a cover 3 having the same spherical inner surface as the male part 1 and adjusted to the end part of the male part 1. The spherical surface of the male part 2, female part 1 and cover 3 is provided with appropriate clearances, and the leakage of a fluid is prevented by an O-ring 5 fitted into an O-ring groove 4. Constantly moving parts are provided with a grease nipple 6 and a grease sump 7 so as to guarantee smooth movement.

Description

Detailed Description of the Invention

1.

[Field of Industrial Application] The present invention was devised to eliminate the flapping of the hose due to the gun swing motion in the robotization of gun blowing work such as mortar in construction civil engineering, but all other piping It can be used by simplifying construction.

[Prior Art] A fixed angle joint is used to change the direction, and the rotating joint is concentric.

[Problems to be solved by the invention] To give a joint flexibility in direction and shaft rotation

[Means for Solving the Problems] The joint is formed into a spherical body of male, female and cover.

[Operation] 1. Insert the male into the female in Figure 1 and fix it with the cover. 2. 2. Make sure that the male and female and the spherical surface of the cover have an appropriate clearance, and use an O-ring that fits into the O-ring groove to prevent leakage of fluid. Keeping smooth movement by attaching a grease nipple and a glistame when using it in a place that constantly moves

[Embodiment] FIG. Is an assembled sectional view of the present invention. Each pipe is connected to a female screw and a male screw, but when the direction angle is tight, two or more pipes are used in combination.

[Advantages of the Invention] 1. Simplification of piping work 2. Absorption of vibration 3. Possible movement of piping
