摘要:
The invention relates to a valve structure for a sack or the like to be filled with air, which valve structure comprises an essentially cylindrical tubular part (2) extending hermetically from the inside to the outside of the sack and having external threads (21) on the portion outside the sack, a plug with internal threads (13) to be screwed on the external threads (21) of the tubular part (2) to close the end (24) of the tubular part hermetically, and a filling valve (15) in the middle of the plug (1). To facilitate and accelerate the emptying of the sack, the present invention is characterized in that the plug (1) has several air exhaust holes (14) within the area surrounding the filling valve (15), and that at the end of the tubular part (2) facing the plug (1) there is an inner, preferably annular flange part (23), the upper surface of which is pressed hermetically against the lower surface of the plug closing the exhaust holes (14) of the plug, when the plug (1) is entirely screwed in its place.

An air bag for bracing products shipped by a railcar, trailer or overseas container to prevent lengthwise and/or crosswise movement of the cargo includes a first sheet (16) of paperboard having parallel side and end edges folded inwardly defining a planar center section (16a) and overlapping sides (18) and ends (26), a second sheet (24) of paperboard of the same dimension as the center section (16a) facing the center section and having its marginal side and end edges (24a) interposed between the center section (16a) and the overlapping side and end sections of the first sheet and glued to the side (18) and end (26) sections, and an inflatable bladder (22) between the two sheets. The bag is constructed of relatively stiff paperboard of a minimum of two laminated plys. Thus, the overlapping side and end edges of the first sheet define with the second sheet a peripheral border of a minimum of six laminated plys of paperboard. The bag has relatively good vertical stiffness when uninflated making it easy to use. The air bag is further characterized by its ease and economy of manufacture.

A railway wagon buffer comprising an impact plate (101) coupled via a movable spacer (110) with impact-absorbing means for absorbing the impact force imparted to the impact plate (101). The impact-absorbing means comprise a plurality of rotatable energy absorbers (120, 130, 140) arranged along the pathway (115) of the movable spacer (110) to engage with the movable spacer (110) during its movement along the pathway (115), each rotatable energy absorber (120, 130, 140) comprising a rotor (121, 131, 141 ) for absorbing in rotational movement at least part of the kinetic energy of the movable spacer (110).
摘要:
Die Erfindung betrifft eine Stoßdämpfereinrichtung und Anordnung auf einem im Untergestell (10) eines schienengebundenen Güterwagens angeordneten Dämpfertisch (1) und mit im Untergestell (10) angeordneten Stoßbalken, der sich wechselseitig über den Stoßdämpfer (2) zum Untergestell (10) hin abstützt. Zur Verbesserung der Lagerung und Sicherung der Stoßdämpfereinrichtung und zur Reduzierung des Aufwandes für die Montage und Demontage ist die Einrichtung und Anordnung dadurch gekennzeichnet, dass der Stoßdämpfer (2) und der Dämpfertisch (1) eine Baugruppe (Modul) bilden, die auf Konsolen (6) im Untergestell (10) lösbar befestigt ist, wobei der Dämpfer (2) mindestens mit seinen an beiden Enden besonders ausgebildeten Dämpferköpfen (3) auf dem Dämpfertisch (1) aufliegt und auf jeder Seite des Dämpferkopfes (3) unten ein Sicherungselement (4) lösbar befestigt ist, welches den Obergurt (5) des Dämpfertisches (1) hintergreift.
摘要:
Device at cool cargo spaces (1), for securing the cargo sideways, and comprising at least one inflatable body (6) provided between the side wall of the hold (2) and the cargo space (1), whereby said at least one body (6) is arranged in inflated state to fill out essentially all space (3) between the side wall (2) and the cargo, not used for cargo, and thereby at the same time to reduce the volume of cooling air required for cooling the cargo space.
摘要:
On décrit une valve pour un sac ou analogue devant se remplir d'air, laquelle valve comporte un élément tubulaire, étanche et essentiellement cylindrique (2) qui s'étend de l'intérieur à l'extérieur du sac, la partie extérieure de l'élément étant filetée à l'extérieur (21). Un bouchon à filetage interne (13) est destiné à s'enfiler sur le filetage externe (21) de l'élément tubulaire (2) afin de fermer hermétiquement l'extrémité (24) de ce dernier, et une valve de remplissage (15) se trouve au milieu du bouchon (1). Afin que le sac puisse se vider de façon simple et rapide, plusieurs évents (14) ont été ménagés dans le bouchon (1) dans la zone qui entoure la valve de remplissage (15), et l'extrémité de l'élément tubulaire (2) comprend, en face du bouchon (1), une bride interne (23) et de préférence annulaire dont la surface supérieure est serrée de manière hermétique contre la surface inférieure du bouchon et ferme les évents (14) de celui-ci lorsqu'il est entièrement vissé.
摘要:
A lateral pull rod mechanism configured to lock a steel tube support assembly, comprising a pull rod (201), an upper connecting plate (208), a pull rod through hole (202) provided on the upper connecting plate (208), a lower connecting plate (209), a lower lateral pull rod clamping groove (210) provided on the lower connecting plate (209), a middle connecting block (211) disposed between the upper connecting plate (208) and the lower connecting plate (209), a middle lateral pull rod clamping groove (212) provided on the middle connecting block (211), a threaded section (203) provided at the upper end of the pull rod (201), a fastening nut (204) in screwed connection with the threaded section (203), an anti-disengaging portion (205) disposed at the lower end of the pull rod (201) and configured to prevent the pull rod (201) from vertically disengaging from the lower lateral pull rod clamping groove (210), and a lateral stopping plate (206) configured to prevent the anti-disengaging portion (205) from sliding outwards.
摘要:
A collision energy absorption column (1) is provided on an end side of a railroad vehicle structure (2) and extends from an end beam (72) toward a roof structure (20). The collision energy absorption column (1) includes a outer member (3) made of metal having a transverse cross section thereof of a channel shape or a hollow shape, and a inner member (4) made of reinforced plastic provided along an inner circumference of the outer member (3) and extending in parallel with the outer member (3). The outer member (3) is configured by joining two column halves (6) extending along a column axis after arranging the two column halves (6) are arranged in a direction perpendicular to the column axis of the outer member (3). The joined part of the column halves (6) extends along the column axis. The outer member (3) is coupled to the end beam (72) and the roof structure (20) by a fastener. The inner member (4) extends between the end beam (72) and a lower part of the roof structure (20), excluding the fastening parts.
