Abstract

A mobile conveyor system includes a conveyor having a portion with a first dimension, the first dimension having a value falling within a predetermined range of values. The system also includes a mobile frame assembly for mounting the conveyor thereon. The frame assembly defines a conveyor mounting bed having a second dimension that is adjustable for receiving therein the portion of the conveyor having the first dimension, for mounting the conveyor to the frame assembly.

Claims

1. A mobile frame assembly for mounting a conveyor thereon, the frame assembly comprising:

a skeleton;

a carriage assembly movably coupled to the skeleton for mounting the conveyor thereon, the carriage assembly being movable in a first direction and a second direction with respect to the skeleton, the second direction being substantially opposite the first direction, the carriage assembly including at least one conveyor support for positioning the conveyor thereon, a plurality of wheels rotatably coupled to the at least one conveyor support, and at least one wheel guide for guiding the plurality of wheels in the first direction and the second direction, thereby enabling movement of the carriage assembly in the first direction and the second direction;

a drive system for moving the carriage assembly in the first direction and the second direction, the drive system including, a drive member coupled to the carriage assembly, a drive shaft rotatably mounted to the frame assembly, an idler shaft rotatably mounted to the frame assembly, a first cable having a first end attached to the drive shaft and a second end attached to the drive member, such that rotation of the drive shaft in a third direction produces a corresponding motion of the drive member in the first direction, and a second cable having a first end attached to the drive shaft, a second end attached to the drive member, and a portion intermediate the first and second ends wrapped about the idler shaft, such that rotation of the drive shaft in a fourth direction opposite the third direction produces a corresponding motion of the drive member in the second direction.

2. The frame assembly of claim 1 wherein the carriage assembly further comprises a plurality of spaced-apart wheel brackets, wherein first wheels of the plurality of wheels are rotatably mounted to a first wheel bracket of the plurality of wheel brackets, second wheels of the plurality of wheels are rotatably mounted to a second wheel bracket of the plurality of wheel brackets, and wherein the at least one conveyor support is mounted to at least one wheel bracket of the plurality of wheel brackets.

3. The frame assembly of claim 1 further comprising means operatively coupled to the drive system for moving the carriage assembly.

4. The frame assembly of claim 1 further comprising rotating means operatively coupled to the drive shaft for rotating the drive shaft.

5. The frame assembly of claim 4 further comprising means operatively coupled to the rotating means for providing power to the rotating means for rotating the drive shaft.

6. The frame assembly of claim 1 further comprising a third cable having a first end attached to the drive shaft, a second end attached to the chive member, and a portion intermediate the first and second ends wrapped about the idler shaft, such that rotation of the drive shaft in the fourth, direction produces a corresponding motion of the drive member in the second direction.

7. The frame assembly of claim 1 wherein the at least one wheel guide is rotatably coupled to the skeleton and wherein the conveyor system further comprises means coupled to the at least one wheel guide for rotating the at least one wheel guide to produce a corresponding rotation of a conveyor secured to the carriage assembly.

8. The frame assembly of claim 7 wherein the means for rotating the at least one wheel guide comprises a hydraulic cylinder.

9. A mobile conveyor system comprising:

a mobile frame assembly for mounting a conveyor thereon, the frame assembly defining a conveyor mounting bed having a first end rotatably coupled to the frame assembly, and a second end opposite the first end;

a vehicle coupled to the frame assembly for transporting the frame assembly and the conveyor, wherein the frame assembly is coupled to the vehicle by a swivel assembly to enable the frame assembly to swivel with respect to the vehicle about a substantially vertical axis, and wherein the swivel assembly includes;

an adapter configured for securement to a portion of the vehicle;

a first bracket secured to the adapter;

a first member secured to the frame assembly and pivotably connected to the first bracket so as to enable pivoting of the first member with respect to the first bracket;

a first hydraulic cylinder connected to the adapter and the first member so as to initiate pivoting of the first member with respect to the first bracket upon actuation of the first hydraulic cylinder; and

a second hydraulic cylinder connected to the adapter and the first member so as to initiate, in conjunction with the first hydraulic cylinder, pivoting of the first member with respect to the first bracket upon actuation of the second hydraulic cylinder.

10. The conveyor system of claim 9 wherein the frame assembly is coupled to the vehicle by an adapter having a first portion configured for securement to a portion of the vehicle, and a second portion configured for securement to the frame assembly.

11. The conveyor system of claim 9 wherein the frame assembly is coupled to the vehicle by a swivel assembly to enable the frame assembly to swivel with respect to the vehicle about a substantially vertical axis.

12. The conveyor system of claim 9 wherein the at least one rotatable guide and the conveyor mounting bed do not form part of the conveyor.

13. The conveyor system of claim 9 wherein the swivel assembly further comprises:

a second bracket secured to the adapter; and

a second member secured to the frame assembly and pivotably connected to the second bracket so as to enable pivoting of the second member with respect to the second bracket.
