Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, specifically a hydraulic automatic correction device for belt conveyors. Background Technology

[0002] Belt conveyors are continuous-movement transportation equipment that uses the conveyor belt as both a traction and load-bearing mechanism. Due to their advantages such as large conveying capacity, long conveying distance, safety and reliability, high degree of automation, simple maintenance, and low operating costs, belt conveyors can shorten transportation distances, reduce project costs, and save manpower and material resources. They are widely used in industries such as mining, metallurgy, coal, chemical, cement, and power to transport various solid block, powder, or packaged materials.

[0003] Especially in mining operations, where over 90% of underground transportation is done using belt conveyors, the conveyor belt may shift due to the weight of the material during operation. Once the belt deviates, the running resistance will increase, easily causing belt winding and tearing failures. In severe cases, it may even cause belt breakage or motor stall and burnout, directly affecting production. In such cases, a deviation correction device is needed to correct the belt and prevent damage.

[0004] A search revealed three patent documents: CN217457591U (authorization announcement number) discloses a sensitive hydraulic belt alignment device for a belt conveyor; CN119059219A (application publication number) discloses a sensitive hydraulic belt alignment device for a belt conveyor; and CN222475221U (authorization announcement number) discloses a passive hydraulic automatic belt alignment device for a horizontally turning belt conveyor. These three patent documents, from different perspectives, provide belt alignment devices that meet usage requirements. To facilitate installation and achieve automatic alignment, these patents offer a belt alignment device different from existing technologies, thus meeting the operational requirements of belt conveyors.

[0015] The present invention discloses a hydraulic automatic belt alignment device for belt conveyors. This device utilizes the coordination of an alignment component and a hydraulic system. The idler rollers in the alignment component support the belt of the conveyor. When the belt deviates to the left or right during operation, a vertical roller in the hydraulic system contacts the belt. Under the action of the belt, the vertical roller rotates, changing the pressure within the hydraulic cylinder. This causes the hydraulic oil in the cylinder to flow through a hydraulic oil pipe connected to a four-way valve to the hydraulic pump, extending the hydraulic rod of the pump. Since the hydraulic rod is hinged to a connecting piece, the connecting piece drives the rotating shaft to rotate, thereby pushing the alignment component to rotate.

[0016] Therefore, the hydraulic automatic belt alignment device described in this utility model, through the cooperation of the alignment component and the hydraulic system, utilizes the rotation of the vertical roller in the hydraulic system to drive the hydraulic rod of the hydraulic pump to extend or retract, thereby driving the alignment component to rotate. The idler roller in the alignment component realizes automatic adjustment and correction of the belt deviation, so as to meet the operating requirements of the belt conveyor, thereby reducing operating costs and improving conveying efficiency. Its overall structure is simple, achieves the purpose of automatic alignment, and is suitable for widespread use. Attached Figure Description

[0035] This embodiment is based on Embodiment 1. To facilitate the installation of the vertical roller 35 and the hydraulic cylinder 31, the hydraulic automatic belt alignment device provided in this embodiment is adopted. A horizontally arranged cylinder mounting plate 17 is also provided on the top of the support plate 14. The hydraulic cylinder 31 is fixedly installed on the bottom surface of the cylinder mounting plate 17, while the vertical roller 35 is rotatably installed on the top surface of the cylinder mounting plate 17. The bottom of the vertical roller 35 is rotatably connected to the piston rod of the hydraulic cylinder 31, so that under the action of the belt, the pressure in the hydraulic cylinder 31 is changed by the rotation of the vertical roller 35. The hydraulic oil in the hydraulic cylinder 31 flows to the hydraulic pump 32 through the hydraulic oil pipe 33 connected to the four-way valve 34, so that the hydraulic rod of the hydraulic pump 32 extends, thereby driving the belt alignment component 2 to rotate, so as to realize the automatic adjustment and correction of the belt deviation. Example 3

[0036] This embodiment is based on embodiment 2. In order to protect the rotating shaft 24 and thus increase the service life of the hydraulic automatic correction device, the hydraulic automatic correction device provided in this embodiment is adopted. The correction component 2 also includes a bearing cover 28 and a cover mounting plate 29. The bearing cover 28 is set at the bottom center of the U-shaped frame 21 through the cover mounting plate 29. The rotating shaft 24 is located inside the bearing cover 28 and is fixedly connected to the top of the bearing cover 28. The connecting piece 25 is fixedly connected to the outer side of the bearing cover 28. The hydraulic rod of the hydraulic pump 32 drives the rotating shaft 24 to rotate through the bearing cover 28 connected to the connecting piece 25.

[0037] Furthermore, in the hydraulic automatic alignment device described in this embodiment, a pump mounting plate 18 is also provided in the support frame. The pump mounting plate 18 is disposed in the left longitudinal connecting plate, and the hydraulic pump 32 is mounted in the left longitudinal connecting plate through the pump mounting plate 18. Simultaneously, a pad 19 is also provided in the support frame. The pad 19 is disposed in the front transverse connecting plate, and the bearing seat 16 is mounted in the front transverse connecting plate through the pad 19.

[0038] The working principle of the hydraulic automatic belt deviation correction device for belt conveyors described in this utility model is as follows: When the conveyor belt deviates, regardless of whether the deviation is to the left or right, the deviated belt will drive the vertical roller 35 on the hydraulic cylinder 31 to rotate. The rotating vertical roller 35 will change the pressure inside the hydraulic cylinder 31, thereby causing the hydraulic oil inside the hydraulic cylinder 31 to flow into the hydraulic pump 32 through the hydraulic oil pipe 33 connected to the four-way valve 34. This allows the hydraulic rod of the hydraulic pump 32 to extend, and the connecting piece 25, which is hinged to the hydraulic rod of the hydraulic pump 32, drives the deviation correction component 2 to rotate, thus achieving automatic adjustment and correction of the belt deviation.

[0039] Therefore, the hydraulic automatic belt alignment device described in this utility model utilizes the cooperation of the alignment component 2 and the hydraulic system 3. The idler roller in the alignment component 2 supports the belt of the belt conveyor. When the belt deviates to the left or right during operation, the vertical roller 35 in the hydraulic system 3 contacts and connects with the belt. Under the action of the belt, the vertical roller 35 rotates. The rotation of the vertical roller 35 changes the pressure in the hydraulic cylinder 31, causing the hydraulic oil in the hydraulic cylinder 31 to flow into the hydraulic pump 32 through the hydraulic oil pipe 33 connected to the four-way valve 34. This causes the hydraulic rod of the hydraulic pump 32 to extend. Since the hydraulic rod of the hydraulic pump 32 is hinged to the connecting member 25, the connecting member 25 drives the rotating shaft 24 to rotate, thereby pushing the alignment component 2 to rotate. The idler roller in the alignment component 2 automatically adjusts and corrects the belt deviation.

[0040] In summary, the hydraulic automatic belt alignment device described in this utility model, through the cooperation of the alignment component and the hydraulic system, utilizes the rotation of the vertical roller 35 in the hydraulic system 3 to drive the hydraulic rod of the hydraulic pump 32 to extend or retract, thereby driving the alignment component 2 to rotate. The idler roller in the alignment component 2 is used to automatically adjust and correct the belt deviation, so as to meet the operating requirements of the belt conveyor, thereby reducing operating costs and improving conveying efficiency. Its overall structure is simple, achieves the purpose of automatic belt alignment, and is suitable for widespread use.
