Description

Technical Field

[0001] This application relates to the field of conveying equipment technology, specifically to conveying devices and engineering machinery. Background Technology

[0002] In related technologies, conveying devices are key equipment for continuous material transport. Their core function is to drive belts to rotate in a circular motion via a motor, thereby achieving efficient transfer of blocky, granular, powdery, or packaged items to connect different production stages, reduce manual handling, and are suitable for scenarios such as mines, factories, and logistics.

[0003] However, during the use of the conveying device, problems may arise such as low coaxiality between the drive roller and the drive equipment (such as a motor), causing the drive equipment to swing, and breakage of the coupling between the drive equipment and the drive roller, thereby affecting production efficiency.

[0006] Beneficial effects: By coaxially connecting the rotary output end of the drive equipment with the drive roller, and by slidingly connecting the drive equipment to the overturning limit part on the frame through an anti-rotation bracket, the drive equipment can adapt to changes in position with the drive roller. The anti-rotation bracket can prevent the drive equipment from rotating on its own, thereby driving the roller to rotate without affecting the positional movement of the drive equipment. This ensures that the coaxiality of the rotary output shaft of the drive equipment and the drive roller is maintained at all times, preventing drive equipment swaying and the coupling between the rotary output shaft of the drive equipment and the drive roller from breaking, reducing maintenance frequency and improving production efficiency.

[0011] In one alternative embodiment, the flange seat further includes an end connector having a nut portion and a threaded portion, the nut portion contacting the side of the flange seat away from the outer cone portion, and the threaded portion connecting to a mating shaft located in the shaft mating hole.

The mounting bracket has a first threaded hole, the thrust member includes a threaded section that passes through the first threaded hole and makes limiting contact with the fixed seat, and the nut is disposed on the thrust member and can contact the mounting bracket.

[0015] In one optional embodiment, the anti-rotation bracket includes a first plate, a second plate, and a third plate connected together. The second plate is set at an angle to both the first plate and the third plate. The first plate is connected to the driving device, and the third plate is slidably connected to the anti-rotation limiting part.

[0036] In related technologies, conveying devices are key equipment for continuous material transport. Their core function is to drive belts to rotate in a circular motion via a motor, thereby achieving efficient transfer of blocky, granular, powdery, or packaged items to connect different production stages, reduce manual handling, and are suitable for scenarios such as mines, factories, and logistics.

[0037] However, during the use of the conveying device, problems may arise such as low coaxiality between the drive roller and the drive equipment (such as a motor), causing the drive equipment to swing, and breakage of the coupling between the drive equipment and the drive roller, thereby affecting production efficiency.

[0038] To address the aforementioned technical problems, this application provides a conveying device and engineering machinery to solve or improve the technical problem of poor coaxiality between the drive equipment and the drive drum, thereby increasing production efficiency.

[0039] The following is combined Figures 1 to 7 This describes an embodiment of the present application.

[0040] According to embodiments of this application, in one aspect, a conveying device is provided, such as... Figure 1 and Figure 2 As shown, it includes a frame 1, a drive roller 2, a drive device 3, and an anti-rotation bracket 4. The specific scheme is as follows.

[0041] The frame 1 is a welded steel frame, and an anti-rotation limiting part 11 is provided on the frame 1.

[0042] like Figure 1 and Figure 2 As shown, the drive roller 2 is rotatably mounted on the frame 1. Specifically, both ends of the drive roller 2 are rotatably connected to the frame 1 through a bearing. The drive roller 2 is used to drive the conveyor belt 8 on the frame 1 to rotate for material transfer. More specifically, at least one passive roller is provided on the frame 1 to support the conveyor belt 8 together with the drive roller 2.

[0043] like Figure 1 and Figure 2 As shown, the drive device 3 can be a motor, or a motor with a reducer (specifically, the reducer and the motor are an integrated structure, that is, the reducer is integrated on the motor). The rotation output end of the drive device 3 is coaxially driven and connected to the drive roller 2; specifically, the rotation output end of the drive device 3 is the rotation shaft of the motor, or the rotation output shaft of the reducer.

[0044] like Figure 1 and Figure 2As shown, the anti-rotation bracket 4 can be of various types, including metal and high-strength non-metallic materials, and can be selected and set according to the needs and the environment of use. One end of the anti-rotation bracket 4 is connected to the drive device 3 by bolting or welding, and the other end of the anti-rotation bracket 4 is slidably connected to the anti-rotation limiting part 11.

[0045] In specific usage, such as Figure 1 and Figure 2 As shown, during the operation of the conveying device, i.e. the material transfer process, the unevenness of the material on the conveyor belt 8 causes the drive roller 2 to deform or change its relative position with the frame 1. The rotation output end of the drive device 3 is coaxially connected to the drive roller 2. The drive device 3 is slidably connected to the overturning limit part on the frame 1 through the anti-rotation bracket 4, so that the drive device 3 can move synchronously with the drive roller 2 or adapt to change its position. The anti-rotation bracket 4 can prevent the drive device 3 from rotating.

[0046] In this embodiment, such as Figure 1 and Figure 2 As shown, the rotating output end of the drive device 3 is coaxially connected to the drive roller 2. The drive device 3 is slidably connected to the overturning limit part on the frame 1 through the anti-rotation bracket 4. This allows the drive device 3 to adapt to the position changes of the drive roller 2, and the anti-rotation bracket 4 can prevent the drive device 3 from rotating on its own, thereby driving the roller 2 to rotate without affecting the position movement of the drive device 3. This ensures that the coaxiality of the rotating output shaft of the drive device 3 and the drive roller 2 is maintained at all times, preventing the drive device 3 from swinging and the coupling 5 between the rotating output shaft of the drive device 3 and the drive roller 2 from breaking, reducing maintenance frequency and improving production efficiency.

[0047] In one embodiment, such as Figures 3 to 7 As shown, the conveying device also includes a coupling 5, such as Figures 3 to 4 As shown, the coupling 5 includes two connecting parts 51, each including a flange seat 511 and a locking sleeve 512. Specifically, both the flange seat 511 and the locking sleeve 512 are metal parts or alloy parts, and the specific materials can be selectively set according to the usage requirements.

[0048] like Figure 7 As shown, the flange seat 511 is provided with an outer tapered portion 5111 and multiple locking connectors 5112. The locking connectors 5112 can be long bolts. The outer tapered portion 5111 is coaxially provided with a shaft mating hole 5113. Specifically, the shaft mating hole 5113 is provided with a spline portion or at least one keyway; for example... Figure 7As shown, the outer conical portion 5111 is provided with a plurality of shrinkage slits 5114 at circumferential intervals, and the shrinkage slits 5114 are connected to the shaft mating hole 5113; the shrinkage slits 5114 extend along the axial direction of the outer conical portion 5111; specifically, the width of the shrinkage slits 5114 is 2mm to 5mm, and can be any one of 2mm, 3mm, 4mm and 5mm or any range between any two values.

[0049] like Figure 7 As shown, the locking sleeve 512 is provided with an inner conical hole 5121, which is sleeved with the outer conical part 5111. Multiple locking connectors 5112 are axially driven to the locking sleeve 512 along the shaft mating hole 5113. Specifically, the flange seat 511 is provided with an annular flange, and the annular flange is provided with through holes corresponding to the locking connectors 5112 at intervals. Preferably, the multiple through holes are evenly spaced along the circumference of the annular flange. The locking sleeve 512 is provided with a second threaded hole corresponding to the locking connectors 5112, and the locking connectors 5112 are screwed into the threaded holes.

[0050] Among them, such as Figure 1 , Figure 5 and Figure 6 As shown, the shaft mating hole 5113 on any one connecting component 51 is coaxially connected to the drive roller 2, and the shaft mating hole 5113 on the other connecting component 51 is coaxially connected to the rotary output end of the drive device 3. The two flange seats 511 are connected by bolts. Specifically, a connecting shaft is coaxially provided at one end of the drive roller 2. The connecting shaft is mated with the shaft mating hole 5113 on one connecting component 51, and the two are circumferentially locked by a locking pin or spline. The rotary output end of the drive device 3 is mated with the shaft mating hole 5113 on the other connecting component 51, and the two are circumferentially locked by a locking pin or spline.

[0051] In the specific assembly process, such as Figure 6 and Figure 7 As shown, the connection between a connecting component 51 and the rotating output end of the drive device 3 is explained. The locking sleeve 512 and the flange seat 511 are sequentially fitted onto the rotating output end. Then, the locking connector 5112 is rotated, which drives the inner tapered hole 5121 of the locking sleeve 512 to press the outer tapered part 5111 of the flange assembly to deform, and presses it against the rotating output shaft located in the shaft mating hole 5113, thereby realizing the connection between the connecting component 51 and the rotating output shaft of the drive device 3.

[0052] Then repeat the above process to connect another connecting part 51 to the connecting shaft of the drive roller 2, and then connect the two connecting parts 51 with multiple bolts to realize the connection between the rotation output shaft of the drive device 3 and the drive roller 2.

[0053] In this embodiment, the coupling 5 with the above-described structure has a simple structure and high connection strength, which can further prevent the coupling 5 from breaking.

[0054] In one embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, the flange seat 511 also includes an end connector 513. The end connector 513 has a connecting nut portion and a threaded portion. That is, the end connector 513 can be a bolt. The nut portion contacts the side of the flange seat 511 away from the outer cone portion 5111, and the threaded portion is connected to the mating shaft located in the shaft mating hole 5113. Specifically, the end of the mating shaft is provided with a third threaded hole.

[0055] It should be noted that the "connection of the threaded part to the mating shaft located in the shaft mating hole 5113" mentioned above refers to the rotating output shaft of the drive device 3 or the connecting shaft of the drive roller 2.

[0056] In specific use, we will still take the connection component 51 and the rotating output end of the drive device 3 as an example. The locking sleeve 512 and the flange seat 511 are sequentially put on the rotating output end. Then, the locking connector 5112 is rotated, which drives the inner conical hole 5121 of the locking sleeve 512 to press the outer conical part 5111 of the flange assembly to deform and press it against the rotating output shaft located in the shaft mating hole 5113, thereby realizing the connection between the connection component 51 and the rotating output shaft of the drive device 3. Then, the end connector is screwed into the third threaded hole at the end of the rotating output shaft.

[0057] In this embodiment, the provision of the end connector 513 can increase the connection strength between the connecting component 51 and the mating shaft located in the shaft mating hole 5113.

[0058] In one embodiment, such as Figure 1 As shown, the frame 1 is provided with a mounting hole 12, which extends along the material conveying direction. Specifically, the mounting hole 12 is an elongated hole or an elongated hole with one end open. The drive roller 2 can be fixedly installed at any position of the mounting hole 12 along the conveying direction. The anti-rotation bracket 4 slides in contact with the anti-rotation limiting part 11 along the conveying direction.

[0059] Specifically, the drive roller 2 can be connected to the mounting hole 12 at any position along the material conveying direction, so that the drive roller 2 can play a tensioning role.

[0060] In this embodiment, the mounting hole 12 extends along the material conveying direction, and the drive roller 2 can be fixedly installed at any position of the mounting hole 12 along the conveying direction. The anti-rotation bracket 4 slides in contact with the anti-rotation limiting part 11 along the conveying direction, which enables the drive roller 2 to play a tensioning role, thereby eliminating the need to set a tensioning wheel, simplifying the structure of the conveying device and reducing costs.

[0061] In one embodiment, such as Figure 1 and Figure 2 As shown, the conveying device also includes a fixed base 6. The drive roller 2 and the fixed base 6 are rotatably connected by bearings or bushings. The fixed base 6 and the mounting hole 12 are fixedly connected by bolts.

[0062] like Figure 2 As shown, a thrust member 7 is provided on the frame 1. The thrust member 7 is provided with a thrust component 71 that can move along the conveying direction. The thrust component 71 makes a limiting contact with the fixed seat 6 to pre-position the drive roller 2 and prevent the position of the drive roller 2 from changing.

[0063] In one embodiment, such as Figure 2 As shown, the thrust member 7 includes a mounting bracket 72, a thrust member 71, and a nut 73. The thrust member 71 includes a threaded section, i.e., the thrust member 71 is a bolt. The mounting bracket is a frame made by bending a metal plate. The mounting bracket 72 is provided with a first threaded hole. The threaded section passes through the first threaded hole and makes a limiting contact with the fixed seat 6. The nut 73 is provided on the thrust member 71 and can contact the mounting bracket 72.

[0064] In specific usage, such as Figure 2 As shown, when the position of the drive roller 2 needs to be adjusted, first rotate the thrust member 71 so that the part of the thrust member 71 that contacts the fixed seat 6 is displaced relative to the mounting bracket 72, thereby pushing the fixed seat 6 to adjust its position. After the fixed seat 6 is adjusted to the correct position, rotate the nut 73 to make pressure contact between the nut 73 and the surface of the mounting bracket 72, thereby locking the thrust member 71 and preventing the thrust member 71 from rotating. Then, tighten the bolts of the fixed seat 6 and the mounting hole 12 on the frame 1 to complete the position adjustment of the drive roller 2.

[0065] In this embodiment, the mounting bracket 72 is provided with a threaded hole, the threaded section passes through the threaded hole and makes limiting contact with the fixed seat 6, and the nut 73 is set on the bolt and can contact the mounting bracket 72. This arrangement can prevent the thrust member 71 from rotating, thereby preventing the drive roller 2 from loosening during the operation of the conveying device.

[0066] In one embodiment, such as Figure 2As shown, the anti-rotation bracket 4 includes a first plate 41, a second plate 42, and a third plate 43 connected together. Specifically, the first plate 41, the second plate 42, and the third plate 43 can be formed by punching and bending a single plate, or by welding three plates together. The second plate 42 is set at an angle of 120° to 150° with the first plate 41 and the third plate 43. The first plate 41 is connected to the drive device 3, and the third plate 43 is slidably connected to the anti-rotation limiting part 11. More specifically, recessed reinforcing parts or reinforcing ribs are provided at the connection points between the second plate 42 and the first plate 41 and the third plate 43.

[0067] In one embodiment, such as Figure 2 As shown, a limit frame is provided on the frame 1. The limit frame is a support formed by cutting and bending a metal plate. The limit frame has a limit hole, which is an anti-rotation limit part 11. The anti-rotation support 4 is slidably connected to the limit hole. Preferably, the limit hole is set in an open position on the side wall away from the frame 1.

[0068] Specifically, along the axial direction of the drive roller 2, the anti-rotation bracket 4 is spaced apart from the limiting hole, that is, it does not contact the limiting hole.

[0069] In this embodiment, a limiting hole is provided on the limiting frame as the anti-rotation limiting part 11, which has a simple structure and is easy to manufacture.

[0070] According to an embodiment of this application, another aspect provides an engineering machine that includes the conveying device in any of the above embodiments.

[0071] Specifically, construction machinery refers to equipment such as crushing machines that have conveying devices.

[0072] In this embodiment, since the engineering machinery includes a conveying device, which has the same technical effect as the crushing device, it will not be described in detail here.

[0073] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
