Description

Technical Field

[0001] The utility model relates to a conveyor deviation correction device, belonging to the technical field of material conveying. Background Art

[0002] At present, belt conveyors have played an important role in the bulk material transportation industry. During the use of belt conveyors, the overall force of the conveyor belt will change locally. The conveyor belt will deviate from the center line during operation due to the change in force, resulting in deviation. If the deviation reaches a certain extent, it will affect material transportation and even damage the conveyor belt. Since the cost of the conveyor belt accounts for 30% to 50% of the cost of the belt conveyor, the replacement cost of the conveyor belt is relatively high.

[0003] The widely used anti-deviation and correction method in the prior art is to add anti-deviation roller frames and anti-deviation uprights on both sides of the conveyor belt, but this method has limited effect. When the conveyor belt deviates too much locally, the side of the conveyor belt will flip along the side of the upright due to stress, resulting in failure of the anti-deviation function, causing serious wear on the side of the conveyor belt and reducing the service life of the conveyor belt.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] The utility model aims at the deficiencies in the background technology and provides a conveyor deviation correction device, which can solve the problem that the conveyor belt side will flip along the vertical roller side due to stress due to excessive local deviation and cause serious side wear, thereby ensuring stable operation of the conveyor belt.

[0009] The deviation-correcting wheel group comprises two deviation-correcting wheels arranged side by side, the two deviation-correcting wheels are respectively connected to the swing arm seats through swing arms, a third hydraulic cylinder is arranged between the two swing arms, and a deviation-correcting wheel groove is arranged in the deviation-correcting wheel.

[0010] Furthermore, a plurality of rollers distributed in a V-shaped structure are installed above the roller bracket, a conveyor belt is provided above the rollers, and the running direction of the conveyor belt is perpendicular to the length direction of the supporting cross arm.

[0011] Furthermore, the tail of the first hydraulic cylinder is hingedly connected via a supporting cross arm, and the head of the first hydraulic cylinder is connected to the side of the roller bracket via a connecting piece.

[0012] Furthermore, two supporting rollers are provided at the bottom of the roller bracket, and the two supporting rollers are distributed on both sides of the slewing bearing.

[0013] Furthermore, the supporting cross arm and the telescopic arm are both hollow structures, and a second hydraulic cylinder is provided between the two telescopic arms.

[0014] Furthermore, the middle part of the main body of the second hydraulic cylinder is fixedly connected to the supporting cross arm. The second hydraulic cylinder is a double-headed cylinder having two output rods, and the heads of the two output rods are connected to the middle part of the telescopic arm.

[0015] Furthermore, the deviation-correcting wheel and the swing arm seat are connected to both ends of the swing arm.

[0016] Furthermore, two ends of the third hydraulic cylinder are respectively hingedly connected to the middle parts of the two swing arms.

[0017] Furthermore, the side edge of the conveyor belt is located in the correcting wheel groove of the correcting wheel.

[0018] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0019] The utility model arranges a deviation-correcting wheel group on both sides of the conveyor belt running direction, the deviation-correcting wheel group can move toward or away from each other under the action of the second hydraulic oil cylinder, and the deviation-correcting wheels in the deviation-correcting wheel group can also swing under the action of the third hydraulic oil cylinder, so as to ensure that the deviation-correcting wheels can continuously press the side edge of the conveyor belt and suppress its deviation.

[0020] When the deviation-correcting wheel set fails due to an unexpected situation, the first hydraulic cylinder can drive the roller bracket and the roller to swing along the slewing bearing, which can correct the deviation of the conveyor belt and ensure stable operation of the conveyor belt.
