Abstract
Description
Technical Field
[0001] The utility model relates to a rotary platform, in particular to a rotary platform with adjustable turning radius, belonging to the technical field of conveying equipment. Background Art
[0002] In order to improve production efficiency, fermentation beds are increasingly developing towards large-scale and industrialized production, and the most commonly used is the disk fermenter. Usually, several disk fermenters are arranged in a circular array around an axis to form a group. A central rotary seat is installed at the central axis, and an annular guide rail is arranged with the central axis as the center. A radial rotary arm is provided between the central rotary seat and the annular guide rail. The outer end of the radial rotary arm travels along the annular guide rail, causing the radial rotary arm to rotate around the axis of the central rotary seat. A radial conveying mechanism is carried on the radial rotary arm, and the material is fed from the center point. The end of the radial conveying mechanism feeds the material to the feeding ports of the surrounding disk fermenters through a chute. In this way, several disk fermenters can share one radial conveying mechanism, saving equipment investment.
[0003] In the actual engineering application process, large-scale fermentation often involves more than a hundred disk fermenters. The specifications or the positions of the feeding ports of each group of disk fermenters are not the same, resulting in differences in the radius of the annular guide rail, and thus the lengths of the radial rotary arms are inconsistent. The traditional method is to accurately design the matching radial rotary arms according to the different radii of the annular guide rail, resulting in a large number of specifications of the radial rotary arms, which is not convenient for large-scale processing in the workshop.
[0004] In addition, even for the radial rotary arms with the same specification matching, due to certain errors in the production and on-site installation processes, the equipment often needs to be repaired on site, which not only increases the on-site workload but also reduces the aesthetics of the equipment.

Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the application of this application, but such simplifications or omissions shall not be used to limit the scope of the utility model.

Detailed implementation manners
[0025] In the following description of the present utility model, the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating that the device must have a specific orientation.
[0026] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific illustrations. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.
[0028] As Figures 1 to 6 shown, the rotatable platform with adjustable turning radius of the present utility model includes a coaxial central rotary seat 2, an annular guide rail 3 and a radial rotary arm 1. The main body of the central rotary seat 2 is a thrust bearing, and the bottom of the bearing is fixed on the central seat bottom plate 2a. The central end of the radial rotary arm 1 is supported on the central rotary seat 2 and the two rotate synchronously. The outer end of the radial rotary arm 1 is supported on the annular guide rail 3 through a traveling mechanism.
[0029] Above the central rotary seat 2, there is a square frame 4. The lower port of the square frame 4 is provided with an inward flange, and the through hole penetrating the inward flange and the central rotary seat 2 is fixed by bolts.
[0030] On both sides of the square frame 4, there are symmetrically arranged radial adjusting plates 8 parallel to each other. On the outer sides of the vertical walls of the two radial adjusting plates 8, two, three or four sliders 10 are respectively fixed. The centers of the sliders 10 are respectively fixed on the radial adjusting plates 8 through tightening screws 9. On the opposite inner walls at the bottom of the central end of the radial rotary arm 1, there are respectively connected radial guide rails 1a. The two radial guide rails 1a are respectively provided with T-shaped grooves and the openings face each other; the outer ends of the sliders 10 are respectively of T-shaped cross-sections, and the T-shaped heads of the sliders 10 on the same side are respectively embedded in the T-shaped grooves of the radial guide rails 1a.
[0031] The cooperation between the T-shaped head and the T-shaped groove can be further optimized to the cooperation between a dovetail tenon and a dovetail groove. Loosen the nuts of the tightening screws 9 to create a gap between the dovetail tenon of the slider 10 and the dovetail groove of the radial guide rail 1a, and then the radial guide rail 1a can slide relative to the slider 10. In this way, the inner end of the radial rotary arm 1 can adjust its relative position with respect to the axis of the central rotary seat, realizing the adjustment of the actual turning radius of the radial rotary arm. After adjustment to the appropriate position, tighten the tightening screws 9 again to press the dovetail tenon of the slider 10 against the dovetail groove of the radial guide rail 1a, realizing the locking of the radial guide rail 1a relative to the slider 10.
[0032] For example, when the diameter of the annular guide rail 3 is 8 meters or 10 meters, it is only necessary to slide the fixed position of the radial guide rail 1a and the slider 10 relative to each other by 1 meter.
[0033] To accommodate the height errors at both ends of the radial swing arm 1, circular support sleeves 5 are fixedly connected to the middle parts of both sides of the square box 4 parallel to the axis of the radial swing arm 1. The outer ends of the two circular support sleeves 5 are open and are respectively fitted with copper bushes or other self-lubricating bearings 6. Adjusting plate horizontal rotating shafts 7 are respectively inserted into the self-lubricating bearings 6. The outer ends of the two adjusting plate horizontal rotating shafts 7 are fixedly connected to the middle part of the radial adjusting plate 8. In this way, the radial adjusting plate 8 can rotate a certain angle around the adjusting plate horizontal rotating shaft 7 in the middle to accommodate the height errors at both ends of the radial swing arm 1.
[0034] The traveling mechanism includes traveling supports 11 located on both sides of the radial swing arm 1. The bottoms of the traveling supports 11 are respectively supported on the annular guide rail 3 by rollers 13. Driven by the traveling reduction motor 12, the traveling supports 11 travel along the annular guide rail 3 through the rollers 13.
[0035] For annular guide rails 3 with different radii, the traveling supports 11 on both sides need to adjust the angles to make the rollers 13 fit the annular guide rail 3 better and reduce wear. For this purpose, the roots of the traveling supports 11 close to the radial swing arm 1 are respectively hinged to the outer ends of the radial swing arm 1 through vertical rotating shafts 14. Angle adjustment brackets 15 are respectively provided on the inner side walls of the traveling supports 11 close to the radial swing arm 1. The free ends of the angle adjustment brackets 15 are connected to the radial swing arm 1 through angle adjustment screw rods 16.
[0036] By pulling the angle adjustment bracket 15 close to or away from the radial swing arm 1 through the angle adjustment screw rod 16, the traveling support 11 can be rotated a certain angle around the vertical rotating shaft 14 to adapt to the radius of the annular guide rail 3. Start the traveling reduction motor 12, and the rollers 13 carry on the traveling support 11 and the outer ends of the radial swing arm 1 and travel along the annular guide rail 3. The central end of the radial swing arm 1 is supported on the central slewing base 2 and rotates around a fixed axis.
[0037] The radial conveying mechanism 17 is fixed on the radial swing arm 1. Its feed inlet 17a is located on the axis of the central slewing base 2 and opens upward. Its discharge outlet 17b faces downward and is docked with the feed ends of various peripheral devices through a chute. In this way, one radial conveyor can feed multiple peripheral devices.
[0038] The above are only the preferred and feasible embodiments of the present utility model, which show and describe the basic principles, main features and advantages of the present utility model. The patent protection scope of the present utility model is not limited thereby. Those skilled in the art should understand that the present utility model is not restricted by the above embodiments. Except for the above embodiments, without departing from the spirit and scope of the present utility model, the present utility model may have other implementation manners.
