Description

Technical Field

[0001] The utility model relates to the field of coal mine belt conveyor equipment, in particular to a hanging deviation adjusting device. Background Art

[0002] Coal mine belt conveyors have the advantages of simple structure, easy use, flexible operation, easy maintenance and installation, and are indispensable equipment for underground transportation. However, conveyors also have some problems that are difficult to solve. For example, the deviation of the conveyor belt. The deviation of the conveyor belt is mainly caused by improper installation of rollers or drums, insufficient tension or uneven force of the conveyor belt, improper joints, uneven laying, etc. In order to solve the problem of conveyor belt deviation, the deviation adjustment device came into being. However, although the current deviation adjustment device can meet the purpose of correcting the conveyor belt, the deviation adjustment device is generally fixed on a plane and corresponds to the bottom of the conveyor belt. When used in the mine, due to the uneven mine passage, it is difficult to find an installation plane. It is necessary to manually build an installation platform with a suitable height for installing the deviation adjustment device, resulting in a very low installation efficiency of the deviation adjustment device. Therefore, it is necessary to produce a hanging deviation adjustment device to solve the above-mentioned problems. Utility Model Content

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] like Figures 1 to 4 As shown, a hanging type deviation adjustment device comprises a suspension component 1, a supporting bottom beam 2, a swing frame 3 and a deviation adjustment component 4, wherein two groups of suspension components 1 are provided and are respectively fixed above the left and right sides of the supporting bottom beam 2, the swing frame 3 is rotatably installed above the middle part of the supporting bottom beam 2, and the lower end of the deviation adjustment component 4 is fixed above the swing frame 3;

[0020] The suspension assembly 1 includes a connecting plate 11, a connecting frame 12, a latch 13, a locking screw 14 and a hook 15. The connecting plate 11 is fixed to the front and rear sides of the supporting bottom beam 2. The lower end of the connecting frame 12 corresponds to between the two groups of connecting plates 11. The latch 13 passes through the connecting plate 11 and the connecting frame 12. The connecting frame 12 is hinged to the connecting plate 11 through the latch 13. The locking screw 14 passes through the connecting plate 11 and the connecting frame 12. The connecting frame 12 is fixedly connected to the connecting plate 11 through the locking screw 14. The hook 15 is fixed above the connecting frame 12 and opens downward.

[0021] The deviation adjustment device of this design can be directly installed on the frame of the conveyor. During installation, two sets of hooks 15 are hung on the straight rods on both sides of the conveyor belt respectively. The connecting plate 11 is pre-fixed on the left and right ends of the supporting bottom beam 2. The left and right sides of the supporting bottom beam 2 are lifted by a jack, so that the holes on the connecting plate 11 are aligned with the holes on the connecting frame 12, and the pins 13 are inserted into the connecting plate 11 and the connecting frame 12. The connecting plate 11 and the connecting frame 12 are fixed with the locking screws 14, and the jack is removed to complete the fixing of the supporting bottom beam 2. At this time, the deviation adjustment component 4 corresponds to the bottom of the conveyor belt. When the conveyor belt deviates to the left or right, the deviation adjustment component 4 is driven by the conveyor belt and rotates through the swing frame 3 to correct the deviation of the conveyor belt. The advantage of this design is that it can adapt to the complex terrain of the mine and efficiently install the deviation adjustment device.

[0022] The left and right sides and the upper side of the hook 15 are provided with strip-shaped through holes 151 , through which the hook 15 can be conveniently fixed on the conveyor by screws.

[0023] The rotating frame 3 includes a rotating base 31, a rotating shaft 32, a supporting plate 33 and a rotating support plate 34. The rotating base 31 is fixed below the supporting bottom beam 2 and can be adjusted in the left and right directions. The bottom of the supporting plate 33 is slidably connected to the upper end of the supporting bottom beam 2. The lower end of the rotating shaft 32 is rotatably mounted on the rotating base 31. The rotating shaft 32 passes through the supporting bottom beam 2 and the supporting plate 33 in sequence upward. The rotating support plate 34 is fixed to the upper end of the rotating shaft 32. The lower end surface of the rotating support plate 34 contacts the upper end surface of the supporting plate 33. The deviation adjustment component 4 is fixed above the rotating support plate 34.

[0024] The deviation adjustment component 4 is driven by the conveyor belt to drive the rotating support plate 34 and the rotating shaft 32 to rotate on the rotating base 31, thereby realizing the rotation of the deviation adjustment component 4. The support plate 33 is used to support the rotating support plate 34 to ensure that the rotating support plate 34 rotates along the horizontal plane.

[0025] The deviation adjustment component 4 includes a deviation adjustment frame 41, a middle roller 42, a side roller 43 and a vertical roller 44. The deviation adjustment frame 41 is fixed above the rotating frame 3, the middle roller 42 is rotatably installed in the middle of the upper part of the deviation adjustment frame 41, the side rollers 43 are rotatably installed on the left and right sides of the upper part of the deviation adjustment frame 41, the outer sides of the side rollers 43 are inclined upward, and the vertical rollers 44 are vertically arranged and rotatably installed on the left and right sides of the deviation adjustment frame 41, and the vertical rollers 44 correspond to the front sides of the side rollers 43.

[0026] When the conveyor deviation range is not too large, the conveyor belt can be adjusted by using the rule that the conveyor belt "runs backward but not forward". When the conveyor belt deviates, it hits the vertical roller 44, and due to the friction between the vertical roller 44 and the edge of the conveyor belt, it moves forward along the running direction of the conveyor belt, while the vertical roller 44 on the other side moves backward relatively. At this time, the conveyor belt moves toward the side of the vertical roller 44 that rotates backward until it returns to the normal position, thereby realizing the deviation adjustment function.

[0027] In the present design, a limit block 5 is also included. A limit groove 411 is provided at the lower end of the offset adjustment frame 41. The lower end of the limit block 5 is fixed above the supporting bottom beam 2. The upper end of the limit block 5 corresponds to the limit groove 411 and there is a gap between the front and rear sides and the limit groove 411. The position of the limit block 5 on the supporting bottom beam 2 is adjustable along the left and right directions.

[0028] During the rotation of the deflection adjusting frame 41, the limit block 5 cooperates with the limit slot 411 to limit the maximum rotation angle of the deflection adjusting frame 41. The limit block 5 is adjustable in the left and right directions on the supporting bottom beam 2. The further the limit block 5 moves outward, the smaller the maximum rotation angle of the deflection adjusting frame 41.

[0029] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
