Description

Technical Field

[0001] This utility model relates to the field of belt conveyor maintenance and adjustment technology, specifically to a belt conveyor tail tension adjustment device. Background Technology

[0002] Belt conveyors play a vital role in the national economy and social development as a conveying equipment for powdery materials. They are the main form of conveying powdery and granular materials and are widely used in petrochemical, energy, metallurgy, coal and agriculture fields. Because belt conveyors use conveyor belts (usually made of rubber), the belts have a large elongation due to the material, which means that the belts need to be constantly tensioned during use to meet the frictional forces required during the conveying process. Therefore, tensioning devices are installed at the tail end of belt conveyors.

[0003] Traditional belt conveyor tail tensioning devices typically employ an adjusting screw and a tensioning base, such as... Figure 1 As shown, the tail redirecting roller is connected to the tensioning mechanism base via bolts. The tensioning base is connected to the tail support via a tensioning screw. When the adjusting screw is activated, the tail redirecting roller can move back and forth, thereby achieving the purpose of adjusting the conveyor belt tension. However, the removal of the roller is complex and requires the assistance of lifting equipment, making it impossible to quickly replace or repair bearings, conveyor belts, etc. Furthermore, during replacement operations, the tail redirecting roller must be completely removed. It is impossible to fine-tune the roller position and carry out corresponding maintenance operations without removing the roller. The lifting workload is large, and the maintenance takes a long time, which cannot meet the current demand for quick and convenient equipment maintenance. Utility Model Content

[0004] The main purpose of this utility model is to provide a tension adjustment device for the tail of a belt conveyor, which solves the problem that existing belt conveyors cannot be repaired or replaced without removing the rollers when replacing bearings or the annular conveyor belt.

The support frame is detachably connected to the belt conveyor and located on both sides of the redirecting drum. Multiple sets of sliding supports are provided and located inside the support frame. The redirecting drum is rotatably mounted on the sliding member. Under the action of external force, the sliding support separates from the support frame, so that there is a gap between the sliding member and the support frame, thereby allowing the sliding member to move along its own axis. The adjustment assembly includes a tensioning member that passes sequentially through a support frame and a sliding member, a locking member disposed between the tensioning member and the sliding member, and an adjustment member disposed between the tensioning member and the support frame; the tensioning member is arranged parallel to the sliding support member; the locking member fixes the tensioning member and the sliding member together under the action of external force; the adjustment member drives the tensioning member to move along the axial direction of the tensioning member under the action of external force, thereby driving the sliding member to move along the sliding support member to tension or relax the conveyor belt on the belt conveyor.

[0006] As a further improvement of this utility model, the support frame is hollow to form an installation cavity, and a connecting rod is provided at the end of the support frame; the connecting rod is fixedly connected to the belt conveyor by bolts.

[0008] As a further improvement of this utility model, the sliding member includes a sliding support and a sliding groove disposed on the sliding support; the sliding support is slidably connected to the upper slide rail and the lower slide rail through the sliding groove and installed in the mounting cavity.

[0009] As a further improvement of this utility model, the tensioning member includes a tensioning screw; the tensioning screw passes through the support frame and the sliding support respectively; the locking member includes a first locking sleeve and a second locking sleeve disposed on the end of the tensioning screw near the sliding support; the first locking sleeve and the second locking sleeve are respectively located on both sides of the sliding support to clamp the sliding bracket between the first locking sleeve and the second locking sleeve.

[0010] As a further improvement of this utility model, the adjusting component includes a first adjusting sleeve and a second adjusting sleeve disposed on the end of the tensioning screw near the support frame; the first adjusting sleeve and the second adjusting sleeve are respectively located on both sides of the support frame to clamp the support frame between the first adjusting sleeve and the second adjusting sleeve.

[0011] As a further improvement of this utility model, the sliding support is provided with a tensioning groove; the side wall of the tensioning groove is provided with a tensioning hole; the tensioning hole penetrates the tensioning groove; one end of the tensioning screw passes through the adjustment hole and enters the tensioning groove from the tensioning hole; the first locking sleeve is located in the tensioning groove.

[0012] The beneficial effects of this utility model are reflected in: By setting up a support frame connected to the belt conveyor, the support frame is detachably equipped with sliding support components and sliding components. The sliding components are the redirecting rollers on the belt conveyor, which are rotatably connected by bearings. The sliding components are driven by tensioning components to move along the sliding support components, thereby driving the redirecting rollers to move within the support frame and achieving tensioning of the conveyor belt. When replacing the bearing housing of the redirecting rollers or the conveyor belt, part of the sliding support components can be removed, so that there is a gap between the top and bottom of the sliding support. This allows for convenient and quick replacement or maintenance of the redirecting roller bearing housings or the circular conveyor belt. Attached Figure Description

The sliding supports 501 provide support for the redirecting roller 2, replacing the bearing 16 seats of the conventional redirecting roller 2. Through the support provided by the sliding supports 501, during the tensioning of the conveyor belt 9, by loosening the second adjusting screw sleeve 802, the first adjusting screw sleeve 801 is rotated to drive the tensioning screw 601 to move. The sliding supports 501 move along the lower slide rail 402 and the upper slide rail 401 toward the adjusting hole 17, driving the redirecting roller to move, thereby achieving the tensioning of the conveyor belt 9.

When replacing bearing 16 or conveyor belt 9, loosen the first adjusting screw sleeve 801, push the sliding support 501 to slide onto the side slide rail 403, separate the upper slide rail 401 and lower slide rail 402 from the support frame 3, thereby expanding the space of the mounting cavity 10. Then, adjust the redirecting roller 2 to the position where the upper slide rail 401 and lower slide rail 402 have been removed by the tension screw 601. With a gap between the upper and lower parts, the sliding support 501 can move along its own axis (that is, in the direction perpendicular to the support frame 3), which can conveniently and quickly realize the rapid replacement or maintenance of the bearing 16 seat of the redirecting roller 2 or the ring conveyor belt.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
