The device has the advantages that the sliding bracket for mounting the belt carrier roller is in sliding connection with the fixed bracket, so that when a belt deviates, the sliding bracket can automatically slide at the top of the fixed bracket under the action of self weight to realize reset deviation adjustment; moreover, when the deviation amplitude is large, the fixed bracket can be rotated through the deviation adjusting mechanism, and the fixed bracket and the sliding bracket act together, so that the deviation adjusting purpose is further achieved.

Description

Technical Field:

[0001] The utility model relates to the technical field of belt idler frames, and particularly relates to an adjustable deviation belt idler frame. Background Art:

[0002] A belt conveyor is a key device in a coal conveying system, which mainly includes a main frame, a driving device, a roller group, an idler frame, belt idlers, a cleaner, a belt, a safety protection device, etc. Among them, the idler frame and the main frame are fixedly connected by bolts, and the belt idlers are installed on the idler frame to support the belt. However, as the belt is used for a long time, it will age and deform, the edges will wear, or the center of the joint made after the belt is damaged is not correct. All these will cause the tensions on both sides of the belt to be inconsistent, resulting in deviation. Once the belt deviates, problems such as material scattering will occur. In serious cases, it is necessary to stop the machine and adjust it manually, which affects the normal production, and the manual adjustment has a large labor intensity, high cost, and there are relatively large potential safety hazards. Content of the Utility Model:

[0003] The purpose of the utility model is to provide an adjustable deviation belt idler frame.

[0004] The utility model is implemented by the following technical solution: An adjustable deviation belt idler frame, which includes a base, a fixed bracket, a sliding bracket and an adjustment mechanism. The fixed bracket is horizontally rotatably arranged above the base. The adjustment mechanism is a hydraulic cylinder, and both ends of the hydraulic cylinder are respectively hinged to the base and the fixed bracket; a belt idler is installed in the sliding bracket; and an adjustment mechanism for driving the fixed bracket to rotate horizontally is arranged on the base.

[0005] Further, an arc-shaped chute with an upward opening is formed at the top of the fixed bracket, and the middle part of the sliding bracket is slidably arranged inside the arc-shaped chute.

[0006] Further, the middle part of the bottom end of the fixed bracket is rotatably connected to the base through a bearing.

[0007] Advantages of the utility model: The sliding bracket for installing the belt idler is slidably connected with the fixed bracket. When the belt deviates, under the action of its own weight, the sliding bracket can automatically slide on the top of the fixed bracket to achieve reset adjustment; and when the deviation amplitude is relatively large, the fixed bracket can be rotated through the adjustment mechanism, and together with the sliding bracket, the purpose of further adjustment can be realized. Description of the Drawings:

[0008] Figure 1 is the overall structural schematic diagram of this embodiment;

[0009] Figure 2 is the schematic diagram when the belt deviates.

[0011] Base 1, fixed bracket 2, sliding bracket 3, deviation adjustment mechanism 4, belt idler 5, arc-shaped chute 6, bearing 7. Specific implementation method:

[0012] In the description of the present utility model, it should be noted that when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, when terms such as "first", "second", "third" appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0013] As Figures 1 to 3 As shown, an adjustable belt idler bracket includes a base 1, a fixed bracket 2, a sliding bracket 3 and a deviation adjustment mechanism 4. A fixed bracket 2 is horizontally rotatably provided above the base 1. An arc-shaped chute 6 with an upward-opening notch is provided at the top of the fixed bracket 2. The middle part of the sliding bracket 3 is slidably arranged inside the arc-shaped chute 6; a belt idler 5 is installed on the sliding bracket 3; the belt idler 5 is used to support the belt. When the belt runs off track, it will drive the sliding bracket 3 to slide on the top of the fixed bracket 2, thereby ensuring that there is no relative displacement between the belt and the sliding bracket 3. Moreover, under the self-weight of the sliding bracket 3 of the belt conveyor, it will slide along the arc-shaped chute 6 to the original position to achieve the purpose of resetting and deviation adjustment.

[0014] The middle part of the bottom end of the fixed bracket 2 is rotatably connected to the base 1 through a bearing 7. A deviation adjustment mechanism 4 for driving the fixed bracket 2 to rotate horizontally is arranged on the base 1. The deviation adjustment mechanism 4 is a hydraulic cylinder. The two ends of the hydraulic cylinder are respectively hinged to the base 1 and the fixed bracket 2. By the telescopic movement of the hydraulic cylinder, the horizontal rotation of the fixed bracket 2 around the bearing 7 can be controlled. When the belt runs off track severely, the fixed bracket 2 can be driven to rotate horizontally through the deviation adjustment mechanism 4 until the whole of the fixed bracket 2 and the sliding bracket 3 is in line with the belt axis direction, so that the belt and the sliding bracket 3 can slide and reset better.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
