[0001] The utility model relates to the technical field of conveyors, in particular to a roller frame for a belt conveyor in coal mines underground. Background Technique

[0002] The transport belt conveyor can also be called a conveyor belt, which is usually composed of a motor, a rolling roller and rollers. The underground transport belt conveyor is usually used for the exploitation of mineral resources, and special crawlers and rollers are usually required for the transportation of minerals.

[0003] Among them, during the process of the belt conveyor transporting materials, the belt in the belt conveyor is prone to deviate from the central position, and the current deviation correction method requires the belt conveyor to be shut down for adjustment, resulting in a decrease in the conveying efficiency of the belt conveyor and an increase in the conveying cost.

[0004] Therefore, those skilled in the art urgently need to develop a roller frame for a belt conveyor in coal mines underground. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Please refer to Figure 1 - Figure 2 , the present utility model provides an embodiment: a roller rack for a belt conveyor in a coal mine underground, including a base 1, a roller 2 is rotatably arranged on the base 1, and deviation rectifying rollers 3 are rotatably arranged on the left and right sides of the roller 2; roller brackets 21 are arranged at both ends of the roller 2, the roller brackets 21 are fixedly connected to the base 1, a roller rotating shaft 22 is arranged between the roller 2 and the roller brackets 21 at both ends, and the roller 2 is rotatably connected between the two roller brackets 21 through the roller rotating shaft 22; deviation rectifying roller rotating shafts 31 are rotatably arranged at both ends of the deviation rectifying roller 3, a deviation rectifying roller fixed bracket 32 is arranged on one side of the deviation rectifying roller 3 close to the roller 2, a deviation rectifying roller movable bracket 33 is arranged on the side of the deviation rectifying roller 3 away from the roller 2, and the deviation rectifying roller 3 is rotatably connected to the left deviation rectifying roller fixed bracket 32 and the right deviation rectifying roller movable bracket 33 respectively through the deviation rectifying roller rotating shaft 31, the deviation rectifying roller fixed bracket 32 is fixedly connected to the base 1, the deviation rectifying roller movable bracket 33 is slidably connected to the base 1, and a driving component is connected to the deviation rectifying roller movable bracket 33.

[0019] Furthermore, the driving component includes a motor 6 fixedly connected to the outer side wall of the base 1, a chute 11 is opened at the top of the base 1, a lead screw 5 is rotatably arranged inside the base 1, a moving seat 4 is threadedly connected to the lead screw 5, the top end of the moving seat 4 extends out of the chute 11 and is rotatably connected to the bottom of the deviation rectifying roller movable bracket 33, and the moving seat 4 is slidably connected to the chute 11, the right end of the lead screw 5 extends out of the base 1 and is connected to the motor 6. By driving the lead screw 5 to rotate through the motor 6, through the forward and reverse rotation of the motor 6, the moving seat 4 on the lead screw 5 can move to the left or right simultaneously, thereby realizing the raising of one side of the deviation rectifying roller 3 and the lowering of the other side of the deviation rectifying roller 3.

[0020] Furthermore, the number of the moving seats 4 is two and they are symmetrically arranged left and right. The two moving seats 4 are respectively connected to the deviation rectifying roller movable brackets 33 on their left and right sides. The two deviation rectifying rollers 3 and the deviation rectifying roller fixed brackets 32 and deviation rectifying roller movable brackets 33 on both sides of the deviation rectifying roller 3 are symmetrically arranged left and right, and the length of the deviation rectifying roller movable bracket 33 is greater than the length of the deviation rectifying roller fixed bracket 32. The symmetrical arrangement of this device ensures the adjustment accuracy of the deviation rectifying rollers 3 on both sides, and thus the belt can be slid to the central position by raising one side of the deviation rectifying roller 3 and lowering the other side of the deviation rectifying roller 3.

[0021] Working principle of the utility model: When in use, when the belt deviates from the center, just start the motor 6. The motor 6 drives the lead screw 5 to rotate. Through the forward and reverse rotation of the motor 6, the moving seat 4 on the lead screw 5 can move to the left or right at the same time. Taking the belt deviating to the right as an example, just move the moving seat 4 to the left. The moving seat 4 at the right end jacks up the deviation rectifying roller 3 on the right through the deviation rectifying roller movable bracket 33 on the right. At the same time, the deviation rectifying roller 3 on the left tilts downward. By changing the rolling angle of the edge of the right belt to increase, under the action of the gravity of the belt and the material, the belt can be driven to slide to the center position. The downward tilt of the deviation rectifying roller 3 on the left ensures that the belt slides to the center position more smoothly. By adjusting the deviation rectifying rollers 3 on the left and right sides in the opposite direction at the same time, the operation is convenient and efficient.

[0022] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitution or change, and should be covered by the protection scope of the utility model.
