Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an ultra-low load rotary roller bed. Background Technology

[0002] Traditional rotary rolling presses have wheels located below the frame, and only four wheels. This means that to meet load requirements, the wheels are typically 250mm in size. Furthermore, because there are only four wheels for support, the rotary rolling press frame has high requirements for the profiles used; the profiles cannot be too small. When the conveying load exceeds 4 tons, the profiles typically need to be 150x150 square tubing or larger. At the same time, the direct drive of the wheels by the drive motor also limits the height of the rotary rolling press.

[0003] Multiple limitations make it difficult to reduce the height of the rotary roller bed to around 800mm; the height of the rotary roller bed also determines the height of the conveyor line, so the height is kept between 600-800mm and cannot be reduced, which means that a factory building is needed to sink the equipment into the pit.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] A specific embodiment of this utility model provides an ultra-low heavy-duty rotary rolling bed, combined with an attached... Figure 1 As shown, in this embodiment, the device is mounted on a support 1, which is fixed to the factory ground. A central guide sleeve 2 is provided at the center of the support 1. The central guide sleeve 2 is connected to the rotating frame 3 by a rotating shaft. Several traveling wheels 4 are provided on the side of the rotating frame 3. The traveling wheels 4 are arranged along the tangent direction of the support 1 and are slidably connected to the support 1. A drive mechanism is provided on the outer ring side of the rotating frame 3.

[0029] The driving mechanism includes a driving device 5 and a friction track 6. The friction track 6 is set on the outer ring of the rotating frame 3, and the friction track 6 and the rotating frame 3 are integrated. The driving device 5 is set on the outer edge of the friction track 6. The driving device 5 is used to press the friction to drive the friction track 6 to rotate around the central guide sleeve 2 as the base point.

[0030] Specifically, such as Figure 3 and Figure 4As shown, the fixed device 51 includes an adjusting plate 511 and a fixed frame 512. The adjusting plate 511 is disposed above the fixed frame 512. A drive motor 53 and a cylinder 55 are fixedly installed above the adjusting plate 511. A floating mechanism is disposed below the adjusting plate 511. The floating mechanism includes a return spring 513 and a linear track 514. The return spring 513 is disposed on the side of the linear track 514. In this embodiment, the floating mechanism is configured in two sets to ensure the movement of the mating friction track 6.

[0031] Specifically, the drive device 5 is changed from direct drive to side drive in this embodiment. The drive device 5 is moved to the outside of the friction track 6, which does not affect the driving performance and greatly reduces the height of this embodiment. Figure 2 As shown, the drive motor 53 drives the drive wheel 52 to rotate, causing the friction track 6 to rotate; the pressure roller 54 presses the drive wheel 52 against the friction track 6, providing driving force; the cylinder 55 presses the drive wheel 53 against the friction track, providing clamping force; during the process of the drive wheel 52 driving the track, the friction track 6 provides a positive pressure to the drive wheel 52. Since the friction track 6 cannot be made perfectly circular in actual engineering manufacturing, a floating mechanism is installed below the drive wheel 52 and the drive motor 53. Under the action of spring force, the floating mechanism can adjust according to the curvature of the friction track 6, so that the drive wheel 52 will not be hard-jammed in the non-smooth parts of the friction track 6.

[0032] like Figure 5 As shown, the traveling wheel 4 includes a hub cover 41 and a swivel 42. The swivel 42 is disposed inside the hub cover 41, and the swivel 42 and the hub cover 41 are connected by a rotating shaft. Figure 1 As shown, the external walking wheels 4 are flush with the rotating frame 3, and eight walking wheels 4 are arranged to increase the support points of the rotating frame 3, thereby increasing the maximum load of the rotating frame 3.

[0033] The rotating wheel 42 is made of steel to increase strength. The rotating wheel 42 is equipped with an adjusting screw to facilitate height adjustment and for lowering the height. After the eight traveling wheels 4 are leveled, the shims fix the height. The traveling wheels 4 are externally mounted and installed along the tangent of the bracket 1 to reduce the distance between them and the rotating frame 3, reduce the span, and increase the strength of the frame.

[0034] like Figure 6 As shown, the rotating frame 3 is reinforced, and the roller conveyor is arranged in the part close to the rotating frame 3, with an empty channel A in the middle to ensure the passage of the sinking lifting slide.

[0035] In this embodiment, the height of the rotating roller bed is reduced to 260mm. A height of 260mm ensures that the conveying height meets the process production requirements, eliminating the need for a factory foundation. To meet the conveying needs of the inner and final lines of the conveyor line and maximize the load capacity, this invention achieves a load capacity of 9t. While reducing the height, the sliding plate for the lowering process must maintain passability.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
