DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the accompanying drawings are not drawn in actual proportional relationships. For example, the thickness or width of some layers may be exaggerated relative to other layers.
[0035] It should be noted that similar reference numerals and letters denote similar items in the following accompanying drawings. Therefore, once an item is defined or described in one accompanying drawing, it will not be necessary to further specifically discuss and describe it in the description of the subsequent accompanying drawings.
[0036] Before understanding the shot blasting machine sling in the embodiments of the present application, it should be clear that the shot blasting machine sling has many application scenarios. The production efficiency of the shot blasting cleaning equipment and the quality of the shot blasting have an important impact on the production and quality of the next process. In the shot blasting cleaning equipment, the application of the sling and the layout of the shot blasting machine are important means to improve the capacity of the pass-through shot blasting machine. A good sling design can solve the problem of the shot blasting dead angle of the pass-through shot blasting machine.
[0037] To solve the technical problems in the background art, such as Figures 1-3As shown in the figure, the present application provides a technical solution: a shot blasting machine sling, including: The fixed seat 1 is the basic part of the sling, having a through hole for connecting with the bearing seat 2. The bearing seat 2 is fixed on the fixed seat 1 for supporting and fixing the shaft rod 3. The shaft rod 3 passes through the fixed seat 1 and is arranged inside the bearing seat 2. The shaft rod 3 has a section of keyway 4 and two symmetric protrusions 5. The keyway 4 is used to connect with the motor to realize the driving of the shaft rod. The sleeve 6 is sleeved on the shaft rod 3 and has two symmetric wing plates 7 for connecting with the connecting rod 14. The spring 8 is arranged between the fixed seat 1 and the sleeve 6 for restricting the movement of the sleeve 6 relative to the fixed seat 1. The support plate 9 is in an I shape, having two symmetric secondary plates 10 and a central plate 11. The shaft rod 3 passes through the central plate 11, and the two symmetric secondary plates 10 form two symmetric limiting grooves 12. The slider 13 is slidably connected with the limiting groove 12. The two ends of the connecting rod 14 are respectively hinged with the wing plate 7 and the slider 13. The hanging frame 15 is clamped with the two symmetric protrusions 5 of the shaft rod 3 for hoisting workpieces.
[0038] During the operation, by lifting the sleeve 6, the spring 8 is compressed and the position of the sleeve 6 is lifted at the same time. The wing plate 7 of the sleeve 6 drives the connecting rod 14 to move upward; the connecting rod 14 further drives the slider 13 to slide in the limiting groove 12 towards the axial position of the sleeve 6, realizing the release of the pressure on the side wall of the hanging frame 15. After the replacement of the hanging frame 15, under the action of the spring 8, the slider 13 presses against the side plate 22 of the hanging frame 15 to form a lock. The motor is connected with the shaft rod 3 through the keyway 4 to drive the shaft rod 3 to rotate. The hanging frame 15 rotates under the action of the shaft rod 3.
[0039] Furthermore, in order to facilitate the lifting of the sleeve 6, a pull rod 16 is provided. The pull rod 16 is mainly composed of a U-shaped rod 17 and a handle 18. The pull rod 16 is generally made of high-strength stainless steel material and has good load-bearing performance. The handle 18 is generally sleeved with a soft rubber material to provide a comfortable holding feeling. The U-shaped rod 17 is connected with the sleeve 6 in an articulated manner. The articulated point is located at the upper end of the sleeve 6, enabling the pull rod 16 to rotate freely around the articulated point, thus facilitating the operation of the user.
[0040] It should be noted that in combination with the attached Figures 5-6 , the slider 13: includes a first body 19 and a second body 20. The first body 19 is hinged with the connecting rod 14, and the second body 20 abuts against the inner wall of the hanging frame 15; the slider 13 slides in the limiting groove 12. The cross-sectional area of the second body 20 is set to be larger than the cross-sectional area of the limiting groove 12, which can increase the contact area with the inner wall of the hanging frame (15), can improve the tightness of the contact with the hanging frame 15, and enhance the safety of the sling.
[0041] Further, a rubber anti-slip layer (not shown in the figure) is provided on the surface of the second body 20 in contact with the inner wall of the hanging frame 15. The rubber anti-slip layer is made of a highly elastic rubber material and has a high friction coefficient, which can effectively prevent the hanging frame 15 from slipping off the second body 20 during the hoisting process. The shape of the rubber anti-slip layer matches the shape of the contact surface of the second body 20, and its size is slightly larger than the contact surface to ensure complete coverage of the contact area. Of course, using this flexible material can also enhance the compactness during its compaction process.
[0042] Specifically, in order to improve the stability of the pull rod 16 during the stretching process, a convex ring (21) is provided on the sleeve (6), and the U-shaped rod (17) is hinged to the lower end of the convex ring (21). When pulling up the pull rod 16, the stress area of the sleeve (6) can be increased. At the same time, the stress area of the spring 8 is also increased, improving the service life of the sleeve 6.
[0043] Of course, further two convex rings (21) are provided, respectively located at the upper and lower ends of the U-shaped rod (17). This not only increases the stress area of the sleeve 6 but also improves its strength.
[0044] Furthermore, the hanging frame 15 is mainly composed of a side plate 22 and a bottom plate 23. Components such as hooks are provided below the hanging frame 15 to suspend and lift the workpiece. The hanging frame 15 can be set in different shapes according to needs. The side plate 22 is a rectangular structure or an annular structure, which is welded and fixed to the bottom plate 23 to form a container-like structure with a certain depth. Its bottom plate 23 is generally designed with a hollow to facilitate the suspension of components such as hooks for lifting the workpiece. A number of ribs 24 are evenly provided on the bottom plate 23, and the ribs 24 are evenly arranged in a ring along the shaft rod 3. The function of the ribs 24 is to enhance the stiffness of the bottom plate 23 and prevent the bottom plate 23 from deforming during the loading process. The ribs 24 are made of the same high-strength steel as the bottom plate 23, and its cross-sectional shape is rectangular, and the size is designed according to the size and load-bearing capacity of the bottom plate 23.
[0045] Further, one side thereof is provided with an arc surface. This arc surface is designed to contact the side plate 22. When the side plate 22 is an annular structure, the arc surface can achieve a large-area contact with it, increasing the contact area and improving the load-bearing capacity of the lifting tool. The contact between the arc surfaces can achieve a better force distribution, reducing the local pressure and avoiding structural damage caused by excessive local pressure.
[0046] Further, the second body 20 is a circular or elliptical structure, and its surface is provided with an arc surface as shown in the attached drawing. The top of the arc surface corresponds to the limit hole, so that the second body 20 can be smoothly accommodated in the limit hole. The arc surface of the second body 20 cooperates with the limit hole of the side plate 22, effectively restricting the movement of the second body 20 in the hanging frame 15.
[0047] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
