Abstract
Description
- This disclosure generally relates to belt conveyor equipment for bulk material transportation. More specifically, the present disclosure relates to a conveyor belt support assembly for a load zone of bulk material transportation equipment.
- Belt conveyors are employed to transport bulk material, such as sand, gravel and the like, from a feed end of a conveyor system, where the material is deposited on the belt, to the opposite end of the conveyor system, where the material is discharged from the belt. Most belt conveyors employ a form of endless belt that is wrapped over a motor-driven head pulley mounted on a frame of the conveyor system at the discharge end and a return idler pulley mounted on the conveyor system frame at the feed end. Between the feed end and the discharge end, the belt is supported on a plurality of troughing idler assemblies that are mounted periodically along the frame of the conveyor.
- A series of troughing idler frames or
supports 10 are shown inFIG. 1 , eachidler frame 10 including abase 12 that mounts to the frame of the conveyor. Connected to eachbase 12 is a plurality of outer perch supports 14A and inner perch supports 14B for supporting threeidler rollers 16A-C in a generally U-shaped configuration. As such,outer supports 14A located at each end ofbase 12 support one end of a shaft carryingoutermost rollers base 12, whileinner supports 14B are positioned onbase 12 to support the ends of a shaft carrying acentral roller 16B as well as an opposite end of theshaft carrying rollers outer supports 14A relative tobase 12. - At the feed end of the conveyor, material is deposited on the belt in a load zone that typically comprises a walled hopper that directs the material onto the belt. As the material strikes the belt, the belt is prone to sagging between adjacent idler assemblies, which can result in material falling off the belt in the load zone area. One known method for addressing this problem involves substituting the two outermost rollers of several idler supports in the load zone with one or more long support rails supported across the several idler supports, such as is disclosed in U.S. Pat. No. 5,350,053. While support rails extend along and support the belt edges in the load zone and prevent belt sagging, they have their drawbacks. For example, wear inevitably occurs on the surface of the support rail in contact with the underside of the belt. While this wear may be localized in only one portion of the support rail, replacement of the entire support rail is required. Due to the large size of the support rail and the presence of the belt, this replacement is difficult, time consuming and costly. Thus, there is a need to improve the support assembly for the load zone of a belt conveyor to overcome these drawbacks.
- Concepts presented herein relate to a cartridge assembly for use in a belt conveyer load zone. The cartridge assembly includes a wear pad, a support plate and a shaft coupled to the support plate. The shaft includes ends that can be coupled to an idler frame of a belt conveyer system. In this manner, the cartridge assembly can be individually replaced as material on the wear pad erodes.
- In a further embodiment, a load zone support assembly includes a plurality of spaced apart idler frames. A plurality of cartridge assemblies are coupled to each idler frame. Each cartridge assembly includes a shaft coupled to the idler frame, a support plate and a wear pad. In a further embodiment, two cartridge assemblies are mounted to each idler frame.
- In yet a further embodiment, a method of providing a load zone for a belt conveyor system is discussed. The method includes providing a plurality of spaced apart idler frames and coupling a plurality of cartridge assemblies to each idler frame: Each cartridge assembly includes a shaft mounted to an idler frame support, a support plate and a wear pad. In a further embodiment, two cartridge assemblies are mounted to each idler frame.

The drawings illustrate embodiments and together with the description serve to explain principles of embodiments.

FIG. 2 is a perspective view of one embodiment of a loadzone support assembly 100. Thesupport assembly 100 includes a plurality of spaced apart idler frames or supports 101-104. Each frame 101-104 includes abase 112 connected to two outer perch supports 114A and two inner perch supports 114B. Frames 101-104 are similar in construction to theidler frames 10 illustrated inFIG. 1 . For instance,outer supports 114A are at a specified height abovebase 112, greater than a specified height ofinner supports 114B abovebase 112. To provide a load zone for a belt conveyor, a plurality ofcartridge assemblies impact roller 122 are coupled to each of the frames 101-104. In particular, one end ofcartridge assemblies outer supports 114A and one end ofcartridge assemblies inner supports 114B.Rollers 122 are supported on either side byinner supports 114B. Together, cartridge assemblies 118, 120 androller 122 form a U-shaped trough to receive material loaded ontoassembly 100. Cartridge assemblies 118 and 120 include coupling mechanisms to allow selective coupling ofcartridge assemblies - Each cartridge assembly supports a conveyor belt such that sag of the belt is substantially prevented between consecutive idler frames (
e.g. frames 101 and 102), as compared to using rollers in consecutive idler frames. In one embodiment, a center-to-center distance of consecutive frames (e.g. frames 101, 102) is approximately 16.0 inches and a width ofcartridge assembly 118 is approximately 10.0 inches. As a result, the distance between consecutive facing edges of cartridge assemblies 118 (e.g., offrames 101 and 102) is about 6.0 inches. In other embodiments, the distance can be in a range between approximately 2.0 inches and 12.0 inches. By providingindividual cartridge assemblies respective cartridge assemblies - By way of example, as illustrated in
FIGS. 3 to 6 ,cartridge assembly 118 includes ashaft 130, asupport plate 132 and first andsecond wear pads Shaft 130 forms recessedgrooves corresponding slots outer support 114A andinner support 114B, respectively. In one embodiment, retainingclips shaft 130 ofcartridge assembly 118 stationary with respect tosupports Shaft 130 is intermediate the width ofsupport plate 132 and is similar in size and construction of corresponding shafts used in conventional idler rollers. Eachwear pad - To assemble
cartridge assembly 118, in one embodiment,support plate 132 is welded toshaft 130, for example using a stitch weld. To couple wearpads plate 132, a plurality offasteners 160 pass through correspondingapertures 162 inwear pads apertures 164 insupport plate 132.Fasteners 162 can then be secured using corresponding nuts 166. Once assembled,cartridge assembly 118 can be easily coupled to an idler frame, such asframe 101, to support a belt 170 (FIG. 3 ). As illustrated, wearpads belt 170. This planar contact provides a wide support so as to substantially prevent sag between adjacent frames in loadzone support assembly 100, yet still be easily replaced once wearpads belt 170 than tangential contact provided by a roller, such asrollers FIG. 1 . -
FIGS. 6 and 7 illustratewear pad 138.Apertures 162 include abore 180 and countersink 182 to accommodatefasteners 160. Additionally, as desired,wear pad 138 can include abeveled edge 184 around a perimeter of thewear pad 138. In one embodiment,wear pad 138 is formed of ultra high molecular weight polyethylene. During use, wearpads 138 are exposed to impact from materials loaded onto loadzone support assembly 100 as well as friction betweenbelt 170 and wearpad 138. The impact and friction cause material ofwear pad 138 to erode and eventually require replacement, so as to prevent damage tobelt 170. -
FIG. 9 is a perspective view of analternative cartridge assembly 200.Cartridge assembly 200 includes ashaft 202,support plate 204 and awear pad 206. In this embodiment, only a single wear pad is provided. Theshaft 202 is approximately centered with respect to thesupport plate 204 and wearpad 206. Thecartridge assembly 200 can be mounted to any of the support frames 101-104 to provide a load zone. In turn, thecartridge assembly 200 provides planar contact with a belt to substantially prevent sag of the belt. - Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and/or equivalent implementations may be substituted for the specific embodiments shown and described without departing from the scope of the present invention.
