Cable and hose carrier support system
View Patent ↗A cable and hose carrier support framework or walker is engaged by and independently driven by the carrier at an arcuate bend thereof for transferring a portion of a carrier load from the bend to a support surface beneath the lower run of the carrier in a manner which will prevent cogging and undue wear of the carrier.
1. A cable and hose carrier support system comprising:
a cable and hose carrier having a plurality of chain links pivotally connected together for movement through an arcuate bend between a lower run connected to a fixed point and an upper run joined to a movable member, the arcuate bend having a bend radius; and
a movable framework engaged and exclusively driven by the cable and hose carrier at the arcuate bend thereof for transferring a portion of a carrier load from the arcuate bend to a support surface underlying the lower run of the carrier so as to prevent undue wear of the carrier,
wherein the movable framework includes a pair of identical, spaced apart, triangularly-shaped framework sections, and
wherein each of the framework sections includes a pair of side members having upper ends joined together and spaced apart lower ends connected together by a bottom member lying generally parallel to the support surface.
2. The support system of claim 1 , wherein junctions between the lower ends of the side members and respective ends of the bottom member are provided with support wheels rollably engageable with the support surface.
3. The support system of claim 2 , wherein the carrier is provided with a set of guide rollers rotatably mounted to outside surfaces of the chain links.
4. The support system of claim 3 , wherein a C-shaped channel is connected to an inside surface of each framework section.
5. The support system of claim 4 , wherein the C-shaped channel extends from the joined upper ends of one of the framework sections to a midportion of a bottom member.
6. The support system of claim 5 , wherein the C-shaped channel defines a cavity for receiving the guide rollers.
7. The support system of claim 6 , wherein the C-shaped channel is formed with a bend radius slightly larger than the bend radius of the carrier.
8. The support system of claim 1 , wherein each of the framework sections includes a horizontally extending beam attached to midportions of the side members and extending rearwardly thereof.
9. The support system of claim 8 , wherein a rear portion of each beam is provided with a first pair of spaced apart, rotatably mounted, inwardly facing guide rollers.
10. The support system of claim 9 , wherein top ends of the side members are provided with a second pair of spaced apart, rotatably mounted, inwardly facing guide rollers.
11. The support system of claim 10 , wherein the second pair of guide rollers is positioned forwardly of the bend radius centerline.
12. The support system of claim 10 , wherein bottom ends of the side members are provided with a third pair of spaced apart, rotatably mounted, inwardly facing guide rollers.
13. The support system of claim 12 , wherein the carrier is passed over the second pairs of guide rollers, between the first pairs of guide rollers and under the third pairs of guide rollers.
14. The support system of claim 1 , wherein each of the framework sections includes a horizontally and rearwardly extending beam having a front end attached to tops of the side members, and a back end provided with an inwardly facing, rotatably mounted guide roller.
15. The support system of claim 14 , wherein each back end of the beam is interconnected by a transverse tie bar.
16. The support system of claim 15 , wherein a cylindrical drum is rotatably mounted on opposite sides thereof to junctions between the side members and the beams.
17. The support system of claim 16 , wherein the cylindrical drum has a diameter greater than the bend radius.
18. The support system of claim 17 , wherein the carrier is wound about 180 degrees of the drum and passes between the drum and the guide rollers.
