Description

Technical Field

[0001] The utility model belongs to the technical field of the belt conveyor transmission in the production of ceramsite concrete, and particularly relates to a roller device of a ceramsite concrete production conveyor. Background Art

[0002] Ceramsite concrete is a kind of ceramsite concrete formed by using ceramsite as the coarse aggregate of the concrete and mixing with fine sand and other materials. Ceramsite concrete has a relatively wide application in the industry. Specifically, compared with traditional concrete, ceramsite concrete has higher heat resistance, so it can be used as fireproof building structure materials and the like in the industry.

[0003] In the production process of ceramsite concrete, a belt conveyor is needed. Specifically, materials such as crushed materials and intermediate products after mixing need to be fed and transported through the belt conveyor. The belt conveyor is used to transport materials between different processing equipment. Since the belt conveyor has high transmission efficiency, a large transmission path, and a large amount of transported materials, it is widely used in the production process.

[0004] The main structure of the belt conveyor includes an installation fixing frame, rollers, and a transmission belt, etc. Since the materials for the production of ceramsite concrete have a large density, especially after being mixed with cement and stirred and humidified, the weight of the materials increases significantly. Therefore, relatively high requirements are placed on the stable performance of the conveyor belt. During the transmission process of the belt conveyor, when the rollers support the heavy concrete during the load-bearing process, the belt is prone to deviation from the rollers. If the belt is not corrected in time, the hollow position on the belt will be too large, which is extremely likely to cause the concrete carried on the belt to tip over from the upper side of the rollers and the installation fixing frame. Especially when the carrying capacity is large, once the belt carrying the materials deviates from the rollers, the heavy materials will lose balance on the belt, and a large amount of materials will tip over from the belt, which not only makes the cleaning cumbersome but also easily causes the belt to break. And the latter is more difficult to repair.

[0005] Therefore, it is very important to improve the roller structure to ensure that it can stably support the belt and solve the technical problem that the roller cannot support the belt once the belt deviates. Content of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a roller device of a ceramsite concrete production conveyor.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A roller device of a ceramsite concrete production conveyor, including a belt conveyor roller mechanism, the belt conveyor roller mechanism includes a roller frame, and a plurality of rollers are assembled and connected to the roller frame;

[0009] The idler mechanism of the belt conveyor further includes a horizontal rotation deviation correction component. The rotation deviation correction component includes arc-shaped deviation correction rail plates symmetrically arranged on both sides. An arc-shaped chute is formed at the top of the arc-shaped deviation correction rail plate. An arc-shaped sliding seat, which is slidably connected in the arc-shaped chute, is fixedly connected to the bottom of the idler bracket.

[0010] A connecting beam is fixedly connected between the arc-shaped deviation correction rail plates. A deviation correction motor for driving the idler bracket to rotate and correct deviation is installed at the bottom of the connecting beam.

[0011] The idler mechanism of the belt conveyor further includes a longitudinal rotation deviation correction component for adjusting the angles and heights on both sides of the idler bracket.

[0012] Belt deviation isolation mechanisms are respectively and fixedly connected to both sides of the top of the idler bracket.

[0013] Preferably, the idler bracket includes a horizontal frame part. Vertical frame parts are integrally formed at both ends of the horizontal frame part. An inclined frame part is integrally formed at the top of the vertical frame part.

[0014] Idler brackets are respectively and fixedly connected to both sides of the top of the horizontal frame part. A horizontal idler is rotatably connected between the idler brackets. An inclined idler is rotatably connected between the idler bracket and the inclined frame part.

[0015] Preferably, the output shaft of the deviation correction motor is rotatably connected to the connecting beam.

[0016] The output shaft of the deviation correction motor is fixedly connected to the center position at the bottom of the horizontal frame part.

[0017] Preferably, the longitudinal rotation deviation correction component includes a longitudinal rotation motor. The output shaft of the longitudinal rotation motor is fixedly connected to the center position of the rear side wall of the connecting beam.

[0018] Preferably, the longitudinal rotation deviation correction component further includes installation and fixing frames symmetrically arranged on the front and rear sides. The output shaft of the longitudinal rotation motor is rotatably connected to one side of the installation and fixing frame.

[0019] A rotating shaft is fixedly connected to the center position of the front side wall of the connecting beam. The rotating shaft is rotatably connected to the installation and fixing frame.

[0020] Preferably, the installation and fixing frame includes a U-shaped part. Vertical installation parts are integrally formed on both sides of the U-shaped part. Mounting seats are welded on the vertical installation parts. Mounting holes are formed in the mounting seats.

[0021] Preferably, an obliquely fixed seat vertically arranged is welded to the top of the inclined frame part.

[0022] The belt deviation isolation mechanism is assembled and connected to the top position of the obliquely fixed seat.

[0023] Preferably, the belt offset blocking mechanism comprises a rotating blocking roller rotatably connected to an oblique fixed seat.

[0025] The utility model has the following beneficial effects:

[0026] 1. When the belt is loaded with concrete during transmission (especially when the concrete feeding belt is uneven, resulting in unstable center of gravity), one side of the belt deviates. At this time, the correction motor drives the roller frame clockwise or counterclockwise. At this time, the roller frame slides in an arc on the arc correction rails on both sides. The roller body installed on the roller frame continues to be supported at the bottom of the belt after the angle is adjusted to ensure that the bottom of the belt is not hollowed out and maintain smooth transportation.

[0027] 2. When the belt is excessively deviated to the left, the arc-shaped deviation-correcting rail-connecting beam-roller frame-roller structure rotates to the left side and is raised under the drive of the rotating motor. During the raising process, the belt is lifted up on the deviated side. At this time, under the action of gravity, the belt slides down along the roller structure and adjusts to the initial position. Similarly, when the right side is severely deviated, the right side is lifted up to correct the severely deviated belt in time.

[0028] 3. By fixing an annular stop seat at the inner end of the extended stop roller, when the belt continues to have a tendency to detach from the rotating stop roller, the belt touches the annular stop seat. At this time, the extended stop roller slides and moves, thereby isolating the belt between the annular stop seat and the rotating stop roller, preventing the belt from detaching from the rotating stop roller due to severe deviation.

[0039] Embodiment 1

[0040] As Figure 1-5 shown, a roller device for a ceramsite concrete production conveyor includes a belt conveyor roller mechanism. The belt conveyor roller mechanism includes a roller frame 1, and a plurality of rollers 11 are assembled and connected to the roller frame 1.

[0041] Specifically, the idler 11 rack 1 includes a horizontal rack portion, both ends of the horizontal rack portion are integrally formed with vertical rack portions, and the top of the vertical rack portion is integrally formed with an inclined rack portion; on both sides of the top of the horizontal rack portion, idler racks 1 are respectively fixedly connected, a horizontal idler is rotatably connected between the idler racks 1, and an inclined idler 11 is rotatably connected between the idler rack 1 and the inclined rack portion.

[0042] In order to address the technical defect that once the belt is offset when supporting a heavy concrete material during the belt support process, the belt and the idler cannot be stably supported, resulting in the tipping of the material, the following improvements are made:

[0043] The idler mechanism of the belt conveyor further includes a horizontal rotation deviation correction component. The rotation deviation correction component includes arc-shaped deviation correction rail plates 3 symmetrically arranged on the left and right sides. An arc-shaped chute A is provided at the top of the arc-shaped deviation correction rail plate 3, and an arc-shaped sliding seat 31 slidably connected in the arc-shaped chute A is fixedly connected to the bottom of the corresponding idler rack 1.

[0044] Meanwhile, a connecting beam 32 is fixedly connected between the arc-shaped deviation correction rail plates 3 (both ends of the connecting beam 32 are fixedly connected to the arc-shaped deviation correction rail plates 3 by welding), and a deviation correction motor 4 (a forward and reverse rotation motor is used) for driving the rotation deviation correction of the idler rack 1 is installed at the bottom of the connecting beam 32.

[0045] Specifically, the output shaft of the deviation correction motor 4 is rotatably connected to the connecting beam 32; the output shaft of the deviation correction motor 4 is fixedly connected to the center position at the bottom of the horizontal rack portion.

[0046] When the belt is transporting concrete (especially when the concrete feeding belt is uneven, resulting in unstable center of gravity), if one side of the belt is offset, at this time, under the drive of the deviation correction motor 4, the idler rack 1 is driven clockwise or counterclockwise. At this time, the idler rack 1 slides in an arc on the arc-shaped deviation correction rail plates 3 on both sides, and the idler rack 1 drives the installed roller body to adjust the angle and then continues to support at the bottom of the belt, ensuring that the bottom of the belt is not hollowed out and maintaining stable transportation.

[0047] Embodiment 2

[0048] As Figure 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, when the belt is severely offset to one side, in order to correct the belt in time, the above-mentioned idler mechanism of the belt conveyor further includes a longitudinal rotation deviation correction component for adjusting the angles and heights on both sides of the idler rack 1.

[0049] Specifically, the longitudinal rotation deviation correction component includes a longitudinal rotation motor 5 (the rotation motor uses a forward and reverse rotation motor), and the output shaft of the longitudinal rotation motor 5 is fixedly connected to the center position of the rear side wall of the connecting beam 32.

[0050] Correspondingly, the longitudinal rotation deviation rectifying assembly further includes mounting and fixing frames 6 symmetrically arranged on the front and rear sides, and the output shaft of the longitudinal rotation motor 5 is rotatably connected to one side mounting and fixing frame 6;

[0051] Meanwhile, a rotating shaft is fixedly connected to the center position of the front side wall of the connecting beam 32, and the rotating shaft is rotatably connected to the mounting and fixing frame 6.

[0052] For example, when the belt is too far to the left, at this time, driven by the rotating motor, the arc deviation rectifying rail - connecting beam 32 - roller frame 1 - roller structure rotates to the left and rises. During the rising process, since the deflected side of the belt rises, at this time, under the action of gravity, the belt slides down along the roller structure to the initial position. Similarly, during the severe deflection on the right side, the right side rises, realizing timely correction of the severely deflected belt to the correct position.

[0053] The above-mentioned mounting and fixing frame 6 includes a U-shaped part, and vertical mounting parts are integrally formed on both sides of the U-shaped part. Mounting seats are welded on the vertical mounting parts, and mounting holes are opened on the mounting seats. The mounting and fixing frame 6 is mounted on the frame beam of the belt conveyor by means of bolt fastening through the mounting holes.

[0054] Embodiment 3

[0055] As Figure 1-5 shown, on the basis of the structure of Embodiment 2 in this embodiment, when one side of the belt is severely deflected, in order to prevent the belt from disengaging from the inclined rollers 11 on both sides, such as during the lifting adjustment process. At this time,

[0056] Belt deviation blocking mechanisms are respectively fixedly connected to both sides of the top of the roller frame 1. Specifically, an obliquely fixed seat 2 vertically arranged is welded to the top of the inclined frame part; the belt deviation blocking mechanism is assembled and connected to the top position of the obliquely fixed seat 2.

[0057] The above-mentioned belt deviation blocking mechanism includes a rotating blocking roller 21 rotatably connected to the obliquely fixed seat 2 (a rotating shaft is installed on the rotating blocking roller 21, and the rotating shaft is installed on the obliquely fixed seat 2). The edge position of the belt is blocked through the blocking action of the rotating blocking roller 21.

[0058] Similarly, an extension blocking roller 22 is slidably connected to the top of the rotating blocking roller 21 (the length of the blocking is increased through the extension blocking roller 22 to ensure that even a severely inclined and deflected belt can still be blocked inside the extension blocking roller 22).

[0059] Specifically, a long fixing rod 211 fixedly connected to the top of the rotating blocking roller 21 and slidably connected inside the extension blocking roller 22 is provided (the rotating blocking roller 21 can rotate relative to the long fixing rod), and a blocking nut is threadedly connected to the outer end of the long fixing rod 211.

[0060] At the same time, an annular stop seat 221 is fixedly connected to the inner end of the extended stop roller 22. When the belt continues to tend to separate from the rotating stop roller 21, the belt touches the annular stop seat 221. At this time, the extended stop roller 22 slides and moves, thereby isolating the belt between the annular stop seat 221 and the rotating stop roller 21, preventing the belt from separating from the rotating stop roller 21 due to severe deviation.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
