[0030] It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0031] Before understanding the shot blasting machine lifting appliance in the embodiments of the present application, it needs to be clear that the application scenarios of the shot blasting machine lifting appliance are many, the production efficiency of the shot blasting cleaning equipment, and the quality of the shot blasting have important influence on the production and quality of the next process. In the shot blasting cleaning equipment, the application of the lifting appliance and the arrangement of the shot blasting machine are important means to improve the capacity of the through-type shot blasting machine, and a good lifting appliance design scheme can solve the application problems of various types of workpieces in the shot blasting process.

[0032] To solve the technical problems in the background art, such as Figures 1-4 As shown in the description, the application provides a technical solution: a shot blasting machine lifting tool hook, comprising:

[0033] The pull rod 1 is a cylindrical member made of high-strength metal material, and has a cylindrical cavity 2 inside. The diameter of the cavity 2 is matched with the outer diameter of the lifting rod 9 to ensure that the lifting rod 9 can be smoothly inserted. And the height of the cavity 2 is enough to accommodate the lifting rod 9. A plurality of limiting grooves 3 are arranged annularly around the cavity 2. The shape and size of each limiting groove 3 are matched with the limiting block 5 to ensure that the limiting block 5 can slide in the groove. And it is known that the plurality of limiting grooves 3 are arranged in the middle and lower segments of the cavity 2 in height. In order to leave space above the limiting groove 3 for accommodating the rod end 10 and its upward movement. The spring 4 is arranged in the limiting groove 3. The spring 4 functions to provide a certain reverse elastic force when the limiting block 5 is subjected to an external force moving away from the center axis of the pull rod 1, so that the limiting block 5 can slide and reset in the limiting groove 3. When the limiting block 5 abuts against the inner groove 11, a part of the limiting block 5 is still located in the limiting groove 3, so as to ensure that in the clamping state, the limiting block 5 can not only clamp the rod end 10, but also the lifting rod 9 will not be separated from the pull rod 1 when the pull rod 1 is lifted. The lifting frame 6 has a bottom plate 7 and a side plate 8, and the lifting frame 6 can be a cylinder, a cuboid, a square or other polygon, and the specific shape is set according to the workpiece to be processed. As long as the bottom plate 7 and the side plate 8 form a cavity for accommodating the workpiece.

[0034] Further, in order to improve the stability of the pull rod 1, the reinforcing ring 12 is sleeved into the appropriate position of the pull rod 1, and is arranged corresponding to the limiting groove 3. During installation, ensure that the reinforcing ring 12 is closely combined with the pull rod 1 to increase the stability of the structure. The reinforcing ring 12 can be welded or riveted with the pull rod 1, or it can be integrally formed. Its specific position needs to cover the limiting groove 3. When the pull rod 1 is lifted upward, the upper end of the limiting groove 3 is the main stress part and needs a certain strength, so the reinforcing ring 12 needs to be arranged at the corresponding position of the limiting groove 3 and cover the limiting groove 3, so as to ensure the stability and safety of the lifting tool.

[0035] It should be noted that the rod end 10 is arc-shaped on one side and flat on the other side. The arc-shaped surface and the flat surface are in contact with the limiting block 5 respectively to meet different working requirements. The arc-shaped surface is to facilitate the reduction of friction when the limiting block 5 is extruded by the rod end 10 during the process of the pull rod 1 being pressed down, thereby facilitating the rod end 10 to slide out of the enclosure of the plurality of limiting blocks 5. When the pull rod 1 is pulled, the flat surface is in contact with the limiting block 5. The upper surface of the limiting block 5 is also flat. The flat surface of the rod end 10 can increase the contact area, reduce the pressure, and improve the stress area. In this way, the durability of the lifting tool hook can be improved, and the service life of the lifting tool hook can be improved. During the shot blasting process, the pull rod 1 realizes the stable suspension function of the lifting tool through the interaction between the rod end 10 and the limiting block 5.

[0036] It should be noted that the annular ring 13 is sleeved on the inner groove 11 of the suspender 9, and the structure is annular, which can slide up and down on the inner groove 11. The annular ring 13 has a first surface 14 and a second surface 15. The angle between the first surface 14 and the suspender 9 is an acute angle, and the limiting block 5 has a lower inclined surface 16 parallel to the first surface 14, which facilitates the sliding of the lower inclined surface 16 relative to the first surface 14 during the process of the pull rod 1 sliding down. The angle between the second surface 15 and the suspender 9 is also an acute angle, and the limiting block 5 has an upper inclined surface 17 parallel to the second surface 15, which is beneficial to the sliding of the upper inclined surface 17 relative to the second surface 15 during the process of the pull rod 1 rising.

[0037] Further, the outer diameter of the annular ring 13 is greater than or equal to the diameter of the rod end 10. When the limiting block 5 descends to the lower end of the annular ring 13 along with the pull rod 1, the pull rod 1 is lifted upward, and the upper inclined surface 17 is in contact with the second surface 15. Under the lifting action of the pull rod 1, the plurality of limiting blocks 5 jointly exert an upward force on the annular ring 13. The self-gravity of the annular ring 13 is not enough to resist the pulling force of the plurality of limiting blocks 5, so the annular ring 13 is immediately lifted to the highest position of the inner groove 11. The pull rod 1 continues to move upward, and under the limitation of the rod end 10, the annular ring 13 cannot continue to move upward. Continue to lift the pull rod 1, and the upper inclined surface 17 of the limiting block 5 slides upward relative to the second surface 15 of the annular ring 13, and finally separates from the second surface 15. When the outer diameter of the annular ring 13 is greater than or equal to the diameter of the rod end 10, the limiting block 5 is in contact with the second surface 15 at the same time, so that the unlocking of the rod end 10 is completed.

[0038] Further, the bottom plate 7 is preferably made of high-strength metal material to ensure sufficient stability and durability during use. The bottom plate 7 is provided with hooks 20, which are preferably made of metal and have high strength and wear resistance. The position of the hooks 20 can be adjusted according to the size and weight of the workpiece to ensure that the workpiece remains stable during hanging. Each hook 20 is fixed to the bottom plate 7 by screws or welding, etc. Generally, the hooks 20 are symmetrically arranged to ensure stability during operation. The specific implementation of the hooks 20 provided on the bottom plate 7 can meet the needs of hanging various workpieces and improve work efficiency.

[0039] It should be noted that the hollow strips 18 are uniformly distributed on the surface of the side plate 8, and the distance between adjacent hollow strips 18 is 10-30 mm, which can be determined according to the requirements. The hollow strips 18 allow the steel balls to pass through as shown in the figure, and play a filtering and guiding role. During the shot blasting process, the steel balls enter from the hollow strips 18 of the side plate 8 and strike the workpiece.

[0040] Further, the cross beam 19 is a long strip structure, the length of which is adapted to the length of the diameter of the side plate 8 to ensure that it can stably span the side plate 8. The cross beam 19 is connected to the side plate 8 at both ends to form a support structure. The cross beam 19 is made of high-strength material, such as aluminum alloy or carbon fiber composite material, to ensure its load-bearing capacity and stability. The connection between the cross beam 19 and the side plate 8 is achieved by high-strength bolt connection to ensure the firmness of the connection. The side plate 8 is provided with mounting holes, and the bolt holes on the cross beam 19 correspond to the mounting holes. The cross beam 19 and the side plate 8 are fixed by bolt fastening. During connection, the parallelism of the cross beam 19 and the side plate 8 needs to be ensured to avoid unnecessary friction and noise during use.

[0041] Specifically, hooks 20 are arranged on the cross beam 19 to increase the number of workpieces hung by the hanging frame 6 and further improve the work efficiency of the shot blasting machine hanger. The specific shape of the hook 20 is curved, one end of which is fixed to the cross beam 19, and the other end forms a hook end for hanging or fixing the workpiece.

[0042] 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 alterations can be made without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
