Description

Technical Field

[0001] This utility model relates to the technical field of underground coal mine operation equipment, and in particular to a belt conveyor lifting frame adjustment device. Background Technology

[0002] In the field of underground coal mining operations, the geological conditions of the roadway will change during the tunneling process, depending on the actual underground conditions. After the belt conveyor is installed, the belt will run off track and coal will spill seriously. It is necessary to manually clean the loose coal in the roadway, which wastes manpower and affects the standardization of roadway work. Manual cleaning of loose coal in the roadway also poses a risk of injury from the belt.

[0003] Therefore, to address the aforementioned problems, a belt lifting frame adjustment device is proposed. By welding a semi-circular arc-shaped groove to the top of the lever structure and having an adjustable height structure at the bottom, it facilitates the adjustment of belt frame deviation, saves labor, simplifies construction procedures, ensures the safety of operators, and improves the efficiency of belt frame adjustment. Utility Model Content

[0004] In order to overcome the problems of serious conveyor belt misalignment and coal spillage during underground operations, which require manual cleaning of loose coal in the roadway, wasting manpower, affecting the standardization of roadway work, and posing a risk of injury from the conveyor belt during manual cleaning of loose coal in the roadway.

[0006] Preferably, the first gear is rotated to drive the threaded tube to rotate, and the rotation of the threaded tube drives the threaded rod to move up and down. The limit rod moves up and down to limit the threaded rod, thereby adjusting the height of the adjusting device. Through the rotational connection between the first connecting frame and the second connecting frame, when the operator adjusts the belt deviation, he only needs to use the steel pipe to lift the slot frame to adjust the belt frame and prevent the belt frame from deviating.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 This utility model provides an embodiment of a belt lifting frame adjustment device, including a base 1, a threaded rod 2, a threaded tube 3, a first bevel gear 4, a limiting rod 5, a first connecting frame 6, a second connecting frame 7, a steel pipe 8, a slot frame 9, an adjustment component, a fixing component, and an installation component. The threaded rod 2 is provided on the inner side of the base 1, and the threaded tube 3 is provided on the outer side of the base 1. The threaded tube 3 and the base 1 are connected by a bearing. The first bevel gear 4 is provided below the threaded tube 3. The limiting rod 5 is provided on the inner side of the base 1, and two sets of the limiting rod 5 are provided. The limiting rod 5 and the threaded rod 2 are slidably connected. The first connecting frame 6 is provided above the threaded rod 2, and the second connecting frame 7 is provided on the inner side of the first connecting frame 6. The second connecting frame 7 and the first connecting frame 6 are rotatably connected. The steel pipe 8 is provided above the second connecting frame 7, and a slot frame 9 is provided at one end of the steel pipe 8. An adjustment component is provided on one side of the base 1, a fixing component is provided above the second connecting frame 7, and an installation component is provided on one side of the base 1.

[0022] Please see Figures 2-4 In this embodiment, the adjustment assembly includes a connecting plate 201 and a fixing plate 202. The connecting plate 201 is provided on the outer side of the base 1, and the fixing plate 202 is provided on one side of the connecting plate 201. The adjustment assembly also includes a rotating shaft 203 and a second bevel gear 204. The rotating shaft 203 is provided on the inner side of the fixing plate 202. The rotating shaft 203 and the second bevel gear 204 are connected by a keyway. The second bevel gear 204 and the first bevel gear 4 are meshed together. In use, the rotating shaft 203 rotates to drive the second bevel gear 204 to rotate, and the second bevel gear 204 rotates to drive the first bevel gear 4 to rotate. The adjustment assembly also includes a connecting plate 205 and a handle 206. The connecting plate 205 is provided at one end of the rotating shaft 203, and the handle 206 is provided on one side of the connecting plate 205. In use, the connecting plate 205 rotates by rotating the handle 206, and the rotating shaft 203 rotates by rotating the connecting plate 205.

[0023] The fixing component includes a fixing frame 301 and fixing bolts 302. The fixing frame 301 is provided above the second connecting frame 7, and the fixing bolts 302 are provided on the inner side of the fixing frame 301. The fixing component also includes a threaded hole 303. The threaded hole 303 is provided on the inner side of the second connecting frame 7. The fixing bolts 302 and the threaded hole 303 are threadedly connected. In use, the fixing frame 301 and the second connecting frame 7 are connected and fixed by the threaded connection between the fixing bolts 302 and the threaded hole 303, thereby fixing the position of the steel pipe 8. The mounting component includes a mounting plate 401 and mounting bolts 402. The mounting plate 401 is provided on one side of the base 1. Multiple sets of mounting plates 401 are provided. The mounting bolts 402 are provided on the inner side of the mounting plate 401. In use, the base plate is fixed on the horizontal ground by the mounting bolts 402 and the mounting plate 401, thereby fixing the device.

[0024] During operation, the handle 206 is first rotated to drive the connecting plate 205 and the rotating shaft 203 to rotate, which in turn drives the second bevel gear 204 to rotate. The rotation of the second bevel gear 204 will drive the first bevel gear 4 and the threaded tube 3 connected to it to rotate. Since the threaded tube 3 is connected to the bearing of the base 1 and the threaded rod 2 is threadedly engaged with the threaded tube 3, the threaded rod 2 will move up and down under the rotation of the threaded tube 3. At the same time, the setting of the limit rod 5 ensures the stability of the threaded rod 2 during the movement, preventing it from deflecting or shaking. The threaded rod 2 can be adjusted to a suitable height according to actual needs.

[0025] Connect one end of the card slot frame 9 to the steel pipe 8, ensuring a secure connection. Then, depending on the specific situation of the belt conveyor deviation, align the other end of the card slot frame 9 with the belt conveyor section that needs adjustment. Since the first connecting frame 6 and the second connecting frame 7 are rotatably connected, when the operator uses the steel pipe 8 to lift the card slot frame 9, a lever structure will be formed. This structure can generate a large torque with a small force, thus easily adjusting the belt conveyor. The operator only needs to adjust the position and height of the card slot frame 9 appropriately according to the direction and degree of belt deviation to bring the belt conveyor back to the correct track.

[0026] After adjustment, the position of the steel pipe 8 is fixed by using the fixing bracket 301 and fixing bolt 302 in the fixing assembly; by rotating the fixing bolt 302, it is made to fit tightly with the threaded hole 303 on the inner side of the second connecting bracket 7, thereby ensuring that the steel pipe 8 will not shift or loosen during subsequent use.

[0027] Through the above steps, the first gear is rotated to drive the threaded tube 3 to rotate, and the rotation of the threaded tube 3 drives the threaded rod 2 to move up and down. The limit rod 5 moves up and down to limit the threaded rod 2, thereby adjusting the height of the adjusting device. With the rotational connection between the first connecting frame 6 and the second connecting frame 7, when the operator adjusts the belt deviation, he only needs to use the steel pipe 8 to lift the slot frame 9 to adjust the belt frame and prevent the belt frame from deviating.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
