Description

Technical Field

[0001] This utility model belongs to the technical field of mining equipment, specifically relating to a conveyor belt tensioning mechanism for a mining belt conveyor. Background Technology

[0002] As a key component of belt conveyors, the tensioning mechanism plays a crucial role in the conveyor belt's operation. Currently used tensioning mechanisms are simple in structure, but have a long tensioning stroke. The harsh environment of mines, with its high dust and humidity, makes such long-stroke tensioning mechanisms prone to malfunctions, resulting in time-consuming, labor-intensive, and costly repairs, ultimately impacting production. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a conveyor belt tensioning mechanism for mining belt conveyors. This effectively solves the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a conveyor belt tensioning mechanism for a mining belt conveyor, comprising a redirecting roller mounted on a support, wherein the conveyor belt is rotatably connected to the redirecting roller, characterized in that: the two ends of the central shaft of the redirecting roller are respectively fixed on bearing seats, and a pair of U-shaped slides are respectively mounted on the crossbeam channel steel on both sides of the support and slidably connected to the crossbeam channel steel via two sliders fixed thereto; the bearing seats are fixed to the U-shaped slides; a lead screw is provided inside the crossbeam channel steel; a nut is threaded onto the lead screw, and the nut is located in the groove in the middle of the connecting block; the bottom end of the U-shaped slide is fixed to the connecting block;

[0005] The rotation of the lead screw drives the nut to move linearly in the horizontal direction, which in turn drives the U-shaped slide block to slide on the crossbeam channel steel through the slider, thereby driving the redirecting roller to move and achieve tensioning of the conveyor belt.

[0006] The U-shaped slide is fixed to the bearing seat by the first bolt.

[0007] The U-shaped slide block and the connecting block together wrap around the crossbeam channel steel and are fixed with the second bolt.

[0008] The end face of the crossbeam channel steel is provided with a vertical plate. The clamping plate is fixed to the outside of the vertical plate by bolts. A round hole is opened in the center of the vertical plate. A threaded hole for threaded connection of the lead screw is opened in the center of the clamping plate. The lead screw is sequentially inserted into the threaded hole and the round hole in the center of the vertical plate and is set in the crossbeam channel steel.

[0009] The card plate consists of two 1 / 2 card plates, which facilitates the installation and connection with the lead screw.

[0010] The advantages of this utility model are: simple to use, low manufacturing cost, safe and reliable to use, can shorten the tensioning stroke, realize the tensioning effect of belt conveyor without stopping the machine, and improve production efficiency. Attached Figure Description

[0014] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0015] See Figure 1-2 A conveyor belt tensioning mechanism for a mining belt conveyor includes a redirecting roller 2 mounted on a support 1, and a conveyor belt 3 rotatably connected to the redirecting roller 2. The mechanism is characterized in that: the two ends of the central shaft of the redirecting roller 2 are respectively fixed to bearing seats 4; a pair of U-shaped slide blocks 5 are respectively mounted on crossbeam channel steel 11 on both sides of the support 1 via two sliders 9 fixed thereto, and are slidably connected to the crossbeam channel steel 11; the bearing seats 4 are fixed to the U-shaped slide blocks 5; a lead screw 7 is provided inside the crossbeam channel steel 11; a nut 6 is threaded onto the lead screw 7, and the nut 6 is located in the groove in the middle of a connecting block 8; the bottom end of the U-shaped slide block 5 is fixed to the connecting block 8.

[0016] The rotation of the lead screw 7 causes the nut 6 to move linearly in the horizontal direction, which in turn causes the connecting block 8 to drive the U-shaped slide 5 to slide on the crossbeam channel steel 11 through the slider 9, thereby driving the redirecting roller 2 to move and achieve tensioning of the conveyor belt 3.

[0017] The U-shaped slide 5 is fixed to the bearing seat 4 by the first bolt 10.

[0018] The U-shaped slide block 5 and the connecting block 8 together wrap around the crossbeam channel steel 11 and are fixed with the second bolt 12.

[0019] The end face of the crossbeam channel steel 11 is provided with a vertical plate 13, and the clamping plate 14 is fixed to the outside of the vertical plate 13 by bolts. The vertical plate 13 has a round hole in the center, and the clamping plate 14 has a threaded hole in the center for threaded connection of the lead screw 7. The lead screw 7 is sequentially inserted into the threaded hole and the round hole in the center of the vertical plate 13 and is set in the crossbeam channel steel 11.

[0020] The card plate 14 consists of two 1 / 2 card plates, which facilitates installation and connection with the lead screw 7.

[0021] How to use:

[0022] Using tools, both lead screws 7 are rotated clockwise or counterclockwise at a certain angle, causing the nut 6 to move linearly, forcing the connecting block 8 to move, which in turn drives the U-shaped slide 5 to move forward or backward, thereby driving the redirecting roller 2 to move forward or backward, thus achieving tensioning of the conveyor belt 3.
