[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 7 As shown:

[0029] The utility model provides a hook structure of a shot blasting machine, comprising a door frame 2 located in front of a shot blasting machine body 1, the shot blasting machine body 1 is connected to the door frame 2 through a sliding track 3, a rotating lifting mechanism is slidably arranged on the sliding track 3, the rotating lifting mechanism is a mechanism for lifting and rotating castings, the rotating lifting mechanism comprises a sliding frame 4 slidably arranged on the sliding track 3, two extension rods 5 are slidably penetrated at the bottom of the sliding frame 4, the bottoms of the two extension rods 5 are connected by a sealing cover 8, the setting of the extension rod 5 can play a role in stabilizing the limit and preventing the deviation, a connecting block 9 is arranged on the top surface of the sealing cover 8, a fixed shaft 10 is penetrated in the connecting block 9, a driven pulley 20 is sleeved on the fixed shaft 10, an electric hoist 6 is installed on the sliding frame 4, and the electric hoist The active pulley in the reed 6 is connected to the driven pulley 20 through the chain 7. The electric hoist 6 is composed of a motor, a reducer, a brake, a drum and a chain 7. When the motor is powered on and rotates to drive the high-speed shaft of the reducer to rotate, the driving torque is transmitted to the last large gear of the reducer through the gear. The gear is connected to the hollow shaft through a spline, and the hollow shaft is connected to the drum through a spline. For this reason, the drum is rotated by the torque of the reduction transmission, and then the chain 7 is wound around or disengaged from the drum, so that the weight is lifted or lowered to complete the function of the lifting mechanism. First, the lifting motor is started to lift the weight to an appropriate height, and then the running motor is started to transport the weight to a specified position. The electric hoist 6 is a prior art and is not described in detail in this utility model.

[0030] like Figures 2 to 3 As shown, a support column 11 is provided inside the sealing cover 8, and a plurality of receiving grooves 12 are provided on both sides of the support column 11. A hanger 13 is provided inside the receiving groove 12. The bottom of the receiving groove 12 is hinged to the bottom of the hanger 13 through a rotating shaft 14. The hanger 13 is located inside the receiving groove 12. When the hanger 13 needs to be used, the bottom of the hanger 13 is turned downward with the rotating shaft 14 as the axis. The space gap required for the hanger 13 to turn downward is reserved inside the receiving groove 12, so that the hanger 13 can be completely turned over and opened. The hanger 13 that is flipped open downward abuts against the bottom of the accommodating groove 12, so that the hanger 13 cannot continue to rotate downward. The casting that needs to be cleaned and strengthened is hung on the hanger 13, and enters the interior of the shot blasting room along the lower edge of the sliding track 3 by rotating the lifting mechanism. When it reaches the predetermined position, it stops and starts to rotate, driving the casting on the hanger 13 to rotate with the rotating lifting mechanism. During the rotation process, the gravity of the falling casting itself exerts pressure on the hanger 13, preventing the hanger 13 from moving up and down during the rotation process.

[0031] like Figure 4As shown, a detachable hook head 18 is provided at the bottom of the pillar 11, and a stabilizing ring 16 is provided between the pillar 11 and the hook head 18. The stabilizing ring 16 is threadedly connected to the pillar 11 and the hook head 18 through bolts 17 respectively. The hook head 18 can be used to hang large castings that need to be cleaned and strengthened. The setting of the stabilizing ring 16 meets the hoisting requirements of different castings, and the hook head can be replaced according to different castings, thereby improving the user's operating efficiency.

[0032] like Figures 5 to 7 As shown, the receiving groove 12 and the hanger 13 are connected by a fixing assembly 19, and the fixing assembly 19 includes a moving chamber 191 opened on the inner wall of the receiving groove 12, and a fixing block 192 is arranged inside the moving chamber 191, and a pull rod 193 is rotatably arranged on the top of the fixing block 192, and a slider 194 is arranged on one side of the fixing block 192, and a guide groove 195 is opened in the slider 194, and one end of the pull rod 193 is located in the guide groove 195, and the fixing block 192 and the slider 194 are connected by a compression spring 197, and the receiving groove 12 is provided with a movable chamber 191, and a fixing block 192 is arranged inside the movable chamber 191, and a pull rod 193 is rotatably arranged on the top of the fixing block 192, and a slider 194 is arranged on one side of the fixing block 192, and a guide groove 195 is opened in the slider 194, and one end of the pull rod 193 is located in the guide groove 195, and the fixing block 192 and the slider 194 are connected by a compression spring 197, and a movable chamber 191 is opened on the receiving groove 12. The locking hole 198 communicates with the movable chamber 191, and a push cap 196 matching the locking hole 198 is provided at one end of the slider 194. The push cap 196 passes through the locking hole 198 and extends into the receiving groove 12. Both sides of the hanger 13 are provided with fixing holes 199 matching the corresponding push cap 196. The shape of the hanger 13 is an inverted "U" shape. When the push cap 196 is located in the locking hole 198 and does not extend out of the receiving groove 12, the pull rod 193 hooks the concave part in the guide groove 195. At this time, the user pushes the downwardly flipped hanger 13 into the receiving groove 12. The user presses the cap 196 in the locking hole 198 with his hand through the fixing hole 199, and the pressed cap 196 pushes the slider 194 to slide into the moving chamber 191. During the movement of the slider 194, the pull rod 193 is separated from the recess and moves along the guide groove 195. After the pressing is completed, the slider 194 moves out of the locking hole 198 under the elastic action of the compression spring 197, pushing the cap 196 through the locking hole 198 and snapping into the fixing hole 199, thereby achieving The folded and stored hanger 13 is fixed in the accommodating groove 12, which saves space. When the hanger 13 needs to be unlocked and flipped downward in the fixed state, the user can press the button cap 196 again, and the squeezed button cap 196 moves into the movable chamber 191, driving the slider 194 to move into the movable chamber 191. During the movement of the slider 194, the pull rod 193 hooks the recessed part of the guide groove 195 again, making the slider 194 unable to reset. The button cap 196 releases the restriction on the hanger 13, and then the hanger 13 is unlocked and can be flipped downward.

[0033] like Figure 3As shown, a plurality of hooks 15 are provided at the bottom of the hanger 13. When processing castings of different types and sizes, the provision of the plurality of hooks 15 not only improves the flexibility of adjusting the spacing between the castings, but also helps to better organize and fix the castings.

[0034] like Figure 1 As shown, the shape of the slide track 3 is Y-shaped, which improves the flexibility, space utilization and stability of the equipment, ensures that the shot blasting machine body 1 can efficiently and stably process castings, and improves the shot blasting efficiency of castings.

[0035] When using:

[0036] The user presses the push cap 196 stuck in the fixing hole 199, and the push cap 196 releases the restriction on the hanger 13. The bottom of the hanger 13 turns downward with the axis of the rotating shaft 14. After the downward turning is completed, castings of different sizes can be hung on the hanger 13, and large castings can be hung on the hook head 18. By controlling the electric hoist 6, the castings of the hanger 13 and the hook head 18 are lifted to an appropriate height, and the rotating lifting mechanism is started to place the hanger 13 and the hook head 18 in the shot blasting room for comprehensive cleaning and strengthening. After comprehensive cleaning and strengthening, the user can push the downward turned hanger 13 into the receiving groove 12, and by pressing the push cap 196 again, the push cap 196 can restrict the hanger 13, thereby realizing that the hanger 13 is folded and stored in the receiving groove 12, saving space, avoiding that only one casting can be hung on the hook 18, achieving unified processing of a large number of castings, and improving the shot blasting efficiency of castings.
