[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 to Figure 6 As shown, the present embodiment proposes a hanger-type shot blasting device for a railway freight car carrying saddle, comprising a shot blasting machine body 1, wherein a carrying frame 2 is rotatably connected inside the shot blasting machine body 1, and both ends of the carrying frame 2 are fixedly connected with a carrying rod 3, and the outer side of the carrying rod 3 is slidably connected with a plurality of supporting frames 4, and a positioning mechanism 5 is arranged in the middle of the supporting frame 4, and the positioning mechanism 5 is used to form a position support for the supporting frame 4, and both ends of the supporting frame 4 are fixedly connected with an assembly frame 6, and one side of the assembly frame 6 is slidably connected with a mounting seat 7, and the bottom end of the mounting seat 7 is fixedly connected with a hanging hook 8, and both sides of the assembly frame 6 are provided with a limiting mechanism 9, and the limiting mechanism 9 is used to form a sliding limit of the mounting seat 7;

[0026] Further, the shot blasting machine body 1 mainly uses the shot blasting machine to throw the steel sand and steel shot at high speed and impact on the surface of the bearing saddle. Compared with other surface treatment technologies, it is faster and more effective, and can be used for the casting process after partial retention or stamping. Among them, the shot blasting machine is generally multiple, installed in different positions, and projectiles are projected from different directions to improve the cleaning efficiency and cleaning quality of the shot blasting machine. It is a mature existing technology and will not be repeated here;

[0027] Furthermore, a limiting shaft is fixedly connected to one side of the assembly frame 6, and the mounting seat 7 is slidably connected to the outside of the limiting shaft. Through the structural coordination of the limiting shaft, the limiting shaft can be used to stably guide the displacement of the mounting seat 7 to prevent the displacement of the mounting seat 7 from being offset.

[0028] The positioning mechanism 5 includes a positioning frame 10, a transmission shaft 11, a thread groove 12, a transmission screw 13, a locking pin 14 and a limit slide 15. The middle part of the support frame 4 is fixedly connected with the positioning frame 10, and the bottom end of the positioning frame 10 is rotatably connected with the transmission shaft 11. Both ends of the transmission shaft 11 are provided with thread grooves 12, and the threads of the two thread grooves 12 are in opposite directions. The insides of the two thread grooves 12 are threadedly connected with the transmission screw 13, and one end of the transmission screw 13 located outside the thread groove 12 is fixedly connected with the locking pin 14, and the locking pin 14 is connected to the carrying rod 3 by clamping. Both ends of the positioning frame 10 are slidably connected with the limit slide 15, and one end of the two limit slides 15 is fixedly connected with the two locking pins 14 respectively;

[0029] It can be understood that by rotating the transmission shaft 11 and cooperating with the opening of the two thread grooves 12, the two transmission screws 13 can move into the thread grooves 12 under the limit of the limit slide rod 15, and at the same time, the locking pin 14 moves out of the carrying rod 3, thereby forming a sliding unlocking of the support frame 4, and then the support frame 4 is pulled to slide on the outside of the carrying rod 3 to adjust the distance between adjacent support frames 4;

[0030] Among them, a grip sleeve is fixedly connected to the middle of the transmission shaft 11, and an anti-slip pattern is provided on the outer side of the grip sleeve. Through the setting of the grip sleeve, personnel can conveniently rotate the transmission shaft 11, thereby ensuring the transmission effect of the transmission shaft 11;

[0031] Furthermore, a plurality of locking holes are provided on the outer side of the carrying rod 3, and the locking pin 14 is connected to the inside of the locking hole by snapping. Through the setting of the locking hole, the locking pin 14 can be conveniently connected to the carrying rod 3, thereby ensuring the locking stability of the locking pin 14;

[0032] Example 2

[0033] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a limiting mechanism 9;

[0034] In this embodiment, the limiting mechanism 9 includes an extension frame 16, a support shaft 17, a limiting plate 18 and a stop screw 19. The two sides of the assembly frame 6 are fixedly connected with the extension frame 16, the inner side of the extension frame 16 is rotatably connected with the support shaft 17, the outer side of the support shaft 17 is fixedly connected with the limiting plate 18, and the top end of the support shaft 17 is threadedly connected with the stop screw 19;

[0035] In summary, loosen the anti-rotation screw 19 to make the anti-rotation screw 19 disengage from the extension frame 16, so as to reduce the friction between the support shaft 17 and the extension frame 16, and then rotate the limit plate 18 to make the limit plate 18 disengage from the mounting seat 7, so as to form a sliding unlocking of the mounting seat 7, and then remove the mounting seat 7 from the assembly frame 6, and then replace the suspension hook 8 corresponding to the load-bearing saddle model;

[0036] Here, the top of the extension frame 16 is fixedly connected with an anti-skid pad. By setting the anti-skid pad, when the anti-slip screw 19 contacts the extension frame 16, the friction between the extension frame 16 and the anti-slip screw 19 can be increased to prevent the support shaft 17 from rotating.

[0037] In detail, a contact pad is arranged on the outer side of the limiting plate 18, and the material of the contact pad is rubber;.

[0038] A specific application of the above two embodiments is to hang the bearing saddle inside the shot blasting machine body 1 through the hanging hook 8, and then throw the projectiles to the surface of the bearing saddle through the shot blasting machine body 1 to continuously impact the surface of the bearing saddle to remove the residual stress in the bearing saddle, improve the fatigue life of the bearing saddle, and improve the roughness of its surface. A driving member can be arranged at the top of the shot blasting machine body 1 to drive the bearing frame 2 to rotate, so as to adjust the position of the bearing saddle;

[0039] The transmission shaft 11 can be rotated to cooperate with the opening of the two thread grooves 12, so that the two transmission screws 13 can move into the thread grooves 12 under the limit of the limit slide rod 15, and at the same time, the locking pin 14 is moved out of the carrying rod 3, so as to form a sliding unlocking of the support frame 4, and then the support frame 4 is pulled to slide on the outside of the carrying rod 3 to adjust the distance between adjacent support frames 4, and after the adjustment, the transmission shaft 11 is rotated to cause the transmission screw 13 to move outward until the locking pin 14 is engaged with the carrying rod 3 again, and finally the sliding locking of the support frame 4 is formed, so that the load saddles of different heights can be suspended, and the space inside the shot blasting machine body 1 is more fully utilized;

[0040] The anti-rotation screw 19 can be loosened to make the anti-rotation screw 19 disengage from the extension frame 16, thereby reducing the friction between the support shaft 17 and the extension frame 16, and then the limit plate 18 is rotated to make the limit plate 18 disengage from the mounting seat 7, thereby forming a sliding unlocking of the mounting seat 7, and then the mounting seat 7 is removed from the assembly frame 6, and the suspension hook 8 corresponding to the load-bearing saddle model can be replaced, making the overall operation more convenient.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
