Abstract
A splice plate for monorail track sections includes a mechanism for drawing the sections together and for leveling the top surfaces of the track with respect to one another. A hanger bracket which is used to attach the track to a support structure connects to the track without the use of through bolts thus eliminating the need to predrill holes in the track in order to receive such bolts. The supports themselves are commercially available hardware items and thus are less expensive than supports which are specifically designed for monorail track.
Claims35
A monorail track structure for a monorail vehicle including two sections of monorail track abutted end to end, the monorail track structure comprising:
- a splice plate covering the joint between the two track sections,
- means for fastening the splice plate to the track sections, and
- cam means for drawing the two track sections together by directly applying opposing longitudinal forces to said splice plate and to at least one of said track sections.
A monorail track structure for a monorail vehicle including two sections of monorail track abutted end to end, the monorail track structure comprising:
- a splice plate covering the joint between the two track sections,
- means for fastening the splice plate to the track sections,
- a cam bolt passing through the splice plate and at least one of the track sections for enabling the two track sections to be drawn together by turning the cam bolt against a cam surface on the monorail track structure, and
- adjustment screw leveling means for leveling the top surface of the two track sections with one another.
A monorail track structure for a monorail vehicle carried by the track structure including two sections of monorail track generally abutted end to end, the monorail track structure comprising:
- a splice plate covering the joint between the two track sections and carried by at least one of the track sections, and
- a cam bolt passing through the splice plate and one of the track sections oriented such that the longitudinal axis of the cam bolt is generally transverse to the longitudinal axis of the one track section with the cam bolt engaging the splice plate and the one track section for axially displacing the one track section toward the other track section to draw the end of the one track section toward the end of the other track section by turning the cam bolt such that engagement between the cam bolt, splice plate and the one track section displaces at least one of the track sections in a direction generally transverse to the longitudinal axis of the cam bolt.
A track structure for a monorail vehicle comprising a monorail which is supported for vehicle use, the track structure comprising:
- a monorail track comprising a top rail, a bottom rail and a web portion between the top rail and bottom rail,
- a hanger bracket comprising a head, a foot portion and a body and having a longitudinal axis extending generally from the foot portion toward the head, and
- wherein the head is constructed and arranged to be received adjacent the web between the bottom rail and the top rail of the track and rotated generally about the longitudinal axis of the hanger bracket until the head engages the track coupling the head to the track.
A track structure for a monorail vehicle comprising a monorail which is supported for vehicle use, the track structure comprising:
- a monorail track comprising a top rail, a bottom rail and a web portion between the top rail and bottom rail,
- an upper shoulder formed on the top rail and a lower shoulder formed on the bottom rail,
- an undercut formed between each of the upper and lower shoulders and the web portion of the track,
- a hanger bracket comprising a head, a foot portion and a body portion,
- wherein the head is comprised of a pair of opposed flanges with each flange having a pair of corners with only one corner of each flange being truncated and the corners of the flanges arranged in a generally rectangular pattern, and
- wherein the flanges are received between the upper rail and lower rail and rotated such that one of the truncated corners is rotated toward the top rail and the other of the truncated corners is rotated toward the bottom rail until one of the flanges is received in the upper undercut and the other of the flanges is received in the lower undercut thereby coupling the hanger bracket to the track.
