Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a device for detecting the center of gravity of a section of a belt conveying bulk material. Background Art

[0002] In the process of conveying bulk materials, belt conveyors are usually used. Belt conveyor equipment is generally driven by a driving mechanism. The conveying route of the belt conveyor for conveying bulk materials is equipped with multiple groups of inverted "eight" shaped rollers. The rollers play the role of supporting and conveying the belt. Under normal circumstances, when using a belt to convey bulk materials, the material should be placed in the middle position of the belt section as much as possible to make the belt in a stable state, and the load borne by the driving mechanism is also minimal. If the bulk material on the belt is not placed properly and the position is offset too much, when the belt conveys bulk materials for a long time, the pressure point of the bulk material on the belt will be offset, resulting in a long-term offset of the belt's force point. The belt is prone to offset and get stuck, causing the equipment to stop and affect the conveying work. Summary of the invention

[0003] The utility model aims to provide a device for detecting the center of gravity of a section of bulk materials conveyed by a belt, aiming to solve the problem that it is difficult to detect the distribution of the center of gravity of the bulk materials when the bulk materials are conveyed on the belt.

[0004] The technical solution adopted by the utility model is: a device for detecting the center of gravity of the cross-section of bulk materials conveyed by a belt conveyor, comprising an outer frame, the outer frame is fixed on both sides of the belt conveyor, an inner frame is arranged on the inner side of the outer frame, a spring is installed in the middle and lower part of the top of the outer frame, an upper hinge is installed at the lower end of the spring, the inner frame is connected to the outer frame through the upper hinge, the upper hinge is provided with mounting screw holes with adjustable mounting position, a spirit level is also installed on the top of the inner frame, the inner frame comprises two vertical rods, the vertical rods are respectively located on both sides of the belt of the belt conveyor, an inclined rod is installed at the lower end of the vertical rod, the inclination angle of the inclined rod is the same as the inclination angle of the roller of the belt conveyor, and the top surface of the inclined rod is at the same height as the top surface of the roller.

[0005] A further technical solution of the utility model is: the diagonal rod is connected to the lower end of the vertical rod through a lower hinge, and the lower hinge is provided with a fixing screw. During installation, the inclination angle of the diagonal rod can be adjusted by the lower hinge, and after the angle is determined, it can be tightened and fixed by the fixing screw.

[0006] A further technical solution of the utility model is that the vertical rod is kept at a distance of 5 to 8 cm from the edge of the belt of the belt conveyor.

[0007] The beneficial effect of the utility model is that due to the adoption of the above-mentioned technical scheme, a belt conveyor bulk material cross-section center of gravity detection device of the utility model can detect the center of gravity position deviation of the bulk material on the belt in real time when the belt conveyor is running. If the center of gravity of the bulk material deviates too much and deviates for a long time, the bubble of the spirit level will be on the same side for a long time. The staff can adjust the placement point of the bulk material in time through the feedback of the detection device until the bubble of the spirit level swings left and right, thereby ensuring the normal operation of the belt conveyor - the center of gravity of the bulk material is dispersedly arranged on both sides of the center line of the belt, thereby extending the service life of the belt.

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0014] Example:

[0015] like Figures 1 to 5 A device for detecting the center of gravity of a section of a belt conveyor for bulk materials is shown, comprising an outer frame 1, which is fixed on both sides of the belt conveyor, an inner frame 2 is arranged on the inner side of the outer frame, a spring 7 is installed at the middle and lower part of the top of the outer frame, an upper hinge 3 is installed at the lower end of the spring, the inner frame is connected to the outer frame through the upper hinge, the upper hinge is provided with mounting screw holes 31 with adjustable mounting position, a spirit level 4 is also installed on the top of the inner frame, the inner frame comprises two vertical rods 5, the vertical rods are respectively located on both sides of a belt 81 of a belt conveyor 8, an inclined rod 6 is installed at the lower end of the vertical rod, the inclination angle of the inclined rod is the same as the inclination angle of the roller of the belt conveyor, and the top surface of the inclined rod is at the same height as the top surface of the roller.

[0016] Preferably, the diagonal rod is connected to the lower end of the vertical rod through a lower hinge 9, and the lower hinge is provided with a fixing screw 91. During installation, the inclination angle of the diagonal rod can be adjusted through the lower hinge, and after the angle is determined, it can be tightened and fixed by the fixing screw.

[0017] Preferably, the vertical rod is kept at a distance of 5 to 8 cm from the edge of the belt of the belt conveyor, so that the vertical rod and the belt are kept at a safe distance to ensure that the vertical rod does not touch the belt.

[0018] When a belt conveyor equipped with a belt conveyor bulk material cross-section center of gravity detection device is working, if the bulk material is placed in an improper position and the bulk material is offset on the belt, the belt will fall due to the gravity of the material, and the falling belt will press down the diagonal rod, and the vertical rod will move downward and swing, causing the spirit level to tilt. The staff can judge whether it is necessary to promptly correct the position of the bulk material on the belt based on the degree of tilt, frequency and length of the tilt time period of the spirit level to ensure the normal operation of the equipment.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
