Description

Technical Field

[0001] The utility model belongs to the technical field of belt transmission, in particular to a belt hydraulic automatic deviation-correcting device. Background Art

[0002] Belt conveyors, also known as rubber belt conveyors, are friction-driven machines that continuously transport materials. They are widely used in industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, postal services, printing, and food for assembly, testing, commissioning, packaging, and transportation.

[0003] During operation, belt conveyors can experience varying degrees of deviation depending on factors such as material flow and roller conditions. Failure to adjust the belt in a timely manner can lead to downtime and, in severe cases, belt buckling or tearing. The quality of the deviation-correcting device is directly linked to the proper operation of the conveyor belt and is a crucial component of belt conveyors.

[0004] Current tracking devices primarily come in two types: mechanical and hydraulic. Mechanical tracking, consisting of a set of tracking rollers and a fixed chain, requires real-time adjustments based on factors such as material flow and belt condition, placing a significant burden on operators. Failure to make timely adjustments can cause the belt to deviate and shut down, and in severe cases, even lead to accidents such as belt buckling and tearing.

[0005] The hydraulic correction device consists of a correction roller group and a hydraulic device. The hydraulic device consists of a deviation column, a gear pump, and an oil cylinder. However, the current hydraulic correction device design has defects. When the belt deviates, the force on the deviation roller will become increasingly large, causing the roller to be damaged faster, and eventually leading to correction failure. Utility Model Content

[0006] In order to solve the problem in the prior art that the vertical rollers providing belt correction function are immovable, resulting in severe wear and failure, the utility model provides a hydraulic automatic belt deviation correction device.

[0007] The utility model is realized through the following technical solutions:

[0008] A belt hydraulic automatic deviation-correcting device comprises a frame and a deviation-correcting frame rotatably arranged on the frame, a roller being rotatably provided on the deviation-correcting frame, and deviation-correcting components which can assist the deviation-correcting frame in returning to the corrective position at both ends of the deviation-correcting frame; the deviation-correcting component comprises a deviation-correcting vertical roller rotatably arranged on one side of the deviation-correcting frame, the lower end of the deviation-correcting vertical roller is connected to a gear pump slidably arranged on one side of the frame, and the output shaft of the gear pump is connected to the deviation-correcting vertical roller; the gear pump is connected to a hydraulic cylinder which is installed on the frame and can drive the deviation-correcting frame to rotate through a pipeline.

[0009] The deflection-correcting vertical roller is rubbed by the deflected belt, driving the gear pump to operate and push the deflection-correcting frame to deflect through the hydraulic cylinder, thereby completing the belt correction and restoration; as the deflection-correcting vertical roller contacts the belt, it can push the gear pump to one side, thereby achieving the mobility of the deflection-correcting vertical roller, which helps to reduce the severity of its wear.

[0010] A further improvement of the present invention is that the two deviation-correcting components are arranged at opposite corners of the deviation-correcting frame, so as to reasonably utilize the space on the frame for layout and arrangement.

[0011] A further improvement of the present invention is that the axis of the deviation-correcting roller is perpendicular to the belt, thereby reducing the force transmission loss when the belt rubs the deviation-correcting roller.

[0012] A further improvement of the present invention is that a trolley track for the gear pump to slide is provided on the frame. The trolley track is a movement limiting track of the gear pump to ensure that the movement route of the deviation-correcting vertical roller is fixed.

[0013] A further improvement of the present invention is that the gear pump is provided with a small wheel that can move along the trolley track. By moving the small wheel along the trolley track, it helps to improve mobility.

[0014] A further improvement of the present invention is that the gear pump is connected to a counterweight block via a pull line, which can drive the gear pump to return to the initial position along the trolley track. The counterweight block can pull the gear pump back to the initial position of the trolley track when the deviation correction roller is not under force.

[0015] A further improvement of the present invention is that the frame is provided with a plurality of pulleys for rotating and reversing the pulling wires, which helps to reduce the counterweight of the counterweight block.

[0016] From the above technical solution, it can be seen that the beneficial effects of the utility model are as follows: the deflection-correcting vertical roller is rubbed by the deflected belt, driving the gear pump to operate so as to push the deflection-correcting frame to deflect through the hydraulic cylinder, thereby completing the belt correction and restoration; as the deflection-correcting vertical roller contacts the belt, the gear pump can be pushed to one side, thereby achieving the mobility of the deflection-correcting vertical roller, which helps to reduce the severity of its wear.

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0024] As attached Figure 1-4 As shown, a belt hydraulic automatic deflection correction device comprises a frame and a deflection correction frame 2 rotatably mounted on the frame. Rollers 1 are rotatably mounted on the deflection correction frame 2. Deflection correction components are mounted at each end of the deflection correction frame 2 to assist in returning the deflection correction frame 2 to its proper position. Two deflection correction components are positioned at opposite corners of the deflection correction frame 2. The layout utilizes the space on the frame to optimize its layout.

[0025] The deflection correction component includes a deflection correction roller 41 that is rotatably arranged on one side of the deflection correction frame 2, and the axis of the deflection correction roller 41 is perpendicular to the belt. This reduces the force transmission loss when the belt rubs the deflection correction roller 41. The lower end of the deflection correction roller 41 is connected to a gear pump 42 that is slidably arranged on one side of the frame, and the output shaft of the gear pump 42 is connected to the deflection correction roller 41; the gear pump 42 is connected to the hydraulic cylinder 3 installed on the frame and capable of driving the deflection correction frame 2 to rotate through a pipeline. The deflection correction roller 41 and the gear pump 42 form an oil pump assembly 4 that provides telescopic power to the hydraulic cylinder 3. The rotating deflection correction roller 41 drives the gear pump 42 below to provide power to the hydraulic cylinder 3, pushing the deflection correction frame 2 to deflect in the intended direction, thereby achieving the purpose of correcting the belt.

[0026] The frame is provided with a trolley track 44 for the gear pump 42 to slide. Trolley track 44 defines the movement path of the gear pump 42, ensuring that the movement path of the deflection correction roller 41 is fixed. The gear pump 42 is provided with a trolley wheel 43 that can move along the trolley track 44. The trolley wheel 43 moves along the trolley track 44, which helps improve the mobility of the gear pump 42.

[0027] The gear pump 42 is connected via a pull cable to a counterweight 5 that drives the gear pump 42 back to its initial position along the trolley track 44. The counterweight 5 pulls the gear pump 42 back to its initial position on the trolley track 44 when the deflection correction roller 41 is free of force. The frame is equipped with a rotating pulley 51 equipped with multiple pull cable reversing mechanisms, which helps reduce the counterweight 5.

[0028] To summarize, the operating principle of this device is as follows: when the belt deviates, its edge first strikes the correcting roller 41, causing it to rotate. The rotating correcting roller 41 then drives the gear pump 42 below to provide telescopic power to the hydraulic cylinder 3, pushing the correcting frame 2 in the intended direction, thereby correcting the belt's deviation. When the belt is stable, the correcting roller 41 is returned to its original position via the counterweight 5 and the pulley 51, achieving a constant and adjustable force. This method significantly extends the service life of the correcting roller set 1, effectively correcting the belt's deviation.

[0029] The utility model discloses a belt hydraulic automatic deviation-correcting device. The deviation-correcting vertical roller is rubbed by the deflected belt, which drives the gear pump to operate so as to push the deviation-correcting frame to deflect through the hydraulic cylinder, thereby completing the deviation-correcting and straightening of the belt. As the deviation-correcting vertical roller contacts the belt, the gear pump is pushed to one side, thereby achieving the mobility of the deviation-correcting vertical roller, which helps to reduce the severity of its wear.
