    摘要: The present invention relates to a pipe transport device (10) for transporting a pipe. Said pipe transport device comprises a first transport trolley (12) configured for transporting a first pipe (11), a second transport trolley (15) configured for transporting a second pipe (14), and a coupling device (16) with a coupler (28) for coupling the first transport trolley (12) and the second transport trolley (15). The coupler (28) includes a switching device (37) for switching an engaging member (36), which is part of the coupler (28), from the engaged state to the disengaged state, wherein the switching device (37) includes an operation part (45) for operating the switching device (37) from outside. The operation part (45) is exposed to a space (57) formed between the first pipe (11) when being loaded on the first transport trolley (12) and the second pipe (14) when being loaded on the second transport trolley (15).

    摘要: A pressing ring (131) in which a spigot (105) formed on a second passage forming member (104) is inserted into a socket (103) formed on a first passage-forming member (102) to be joined to the second passage forming member, a peripheral wall (106) protruding inward in a radial direction is formed on an inner periphery of a rear of the socket, and a sealing member insertion space (108) between an opening end face (107) and the peripheral wall of the socket is formed between an outer circumference (105a) of the spigot and an inner circumference (103a) of the socket, the pressing ring being used for a joint (122) including an annular sealing member (123) lying in the sealing member insertion space, the pressing ring being opposed to the opening end face of the socket from outside while being fit onto the spigot, the pressing ring being moved by a pressing member (144) along an axis of the passage forming member in a pressing direction so as to press the sealing member into the sealing member insertion space, the pressing ring having a pressing face (135) that comes into contact with an end (123b) of the sealing member, contact portions (136) that come into contact with the socket so as to keep a distance from the pressing face to the opening end face of the socket at a predetermined distance, and an escaping portion (137) that allows escape of a part of the sealing member pressed by the pressing face.

    摘要: A first projection 19 is formed on the outer periphery of a bulb part 18, a second projection 20 is formed on the socket rear end of the bulb part 18, a tapered part 28 is formed with a decreasing diameter from the inner periphery of a heel part 17 to the inner periphery of the second projection 20, and a third projection 21 is formed on the tapered part 28. A first dimension B from the first.projection 19 to the third projection 21 in an inclination direction opposite to an inclination direction G of the tapered part 28 is smaller than a second dimension C from the first projection 19 to the second projection 20 in a radial direction A.
