[0001] The utility model relates to the technical field of shot blasting equipment, in particular to an improved hook-type shot blasting device. Background technology:

[0002] Shot blasting is a mechanical surface treatment process. The principle of shot blasting is to use an electric motor to drive the impeller to rotate and rely on the centrifugal force to throw the projectile with a diameter of about 0.2 to 3.0 to the surface of the workpiece, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, changing the welding tensile stress of the workpiece into compressive stress, and improving the service life of the workpiece; the shot blasting machine commonly used in the market is the hanging shot blasting machine. The structure of this type of shot blasting machine includes a box, a crane hook, a hanger, a shot blasting wheel, a pneumatic door, etc. When working, the workpiece is The workpiece is hung on the hanger, and then the overhead crane is operated to transport the hanger into the box, the pneumatic door is closed, and the shot blasting machine is started to throw projectiles at the workpiece to clean the workpiece; in actual application, in order to improve the shot blasting efficiency, the hanger is usually full of workpieces. If the workpiece is plate-shaped, it is easy to cause the inside of the workpiece or the workpiece located in the center to not fully contact the projectiles thrown by the shot blasting machine, resulting in incomplete shot blasting on the inside of the workpiece and poor shot blasting effect. If you want to improve the shot blasting effect, you must reduce the number of workpieces on the single shot blasting hanger, resulting in low work efficiency. Utility model content:

[0003] The purpose of the utility model is to provide an improved hook-type shot blasting device to solve the technical problems in the prior art that the inner side of the workpiece cannot fully contact with the projectile during the shot blasting operation, resulting in poor shot blasting effect, and that reducing the workpiece to improve the shot blasting effect leads to low shot blasting efficiency.

[0004] The content of the utility model: An improved hook-type shot blasting device, which includes a box with an opening on one side, the box is fixedly installed on a base, a hook groove is provided at the top of the box, a hook is slidably connected in the hook groove, the top of the hook is rotatably connected to the overhead crane electric hoist, the hook is connected to the hanger assembly, a center column is vertically downwardly connected to the hanger assembly, the bottom of the center column is a square column, a rotating shaft is rotatably connected to the bottom of the box, a square groove matching the square column is provided on the rotating shaft, and the rotating shaft is transmission-connected to the rotary drive assembly.

[0005] Furthermore, the rotary drive assembly includes a worm shaft, the worm shaft is rotationally connected to the base, the worm shaft is engaged with the turbine, the turbine is fixedly mounted on the rotating shaft, and the worm shaft is transmission-connected to the motor.

[0006] Furthermore, the hanger assembly includes two I-beams welded to each other, the two I-beams are arranged in a cross shape, and a plurality of hanging rings are connected to the bottom of the I-beams.

[0007] Furthermore, any two adjacent hanging rings are arranged in a staggered manner.

[0008] Furthermore, a guide angle is provided at the notch position of the square groove.

[0009] Furthermore, a limiting groove is provided in the box body, and a limiting plate is fixedly installed on the hook. The limiting plate is located in the limiting groove, and the limiting groove is used to limit the vertical displacement of the limiting plate.

[0010] The beneficial effects of the present invention are as follows: on the basis of the traditional hook-type shot blasting machine, the present invention designs a rotating shaft device at the bottom of the hanger that can drive the hanger to rotate, and at the same time matches the rotating shaft with a worm gear power system, so that the hanger can rotate during the shot blasting operation. Due to the action of centrifugal force, the workpieces on the hanger are lifted, thereby increasing the gap between adjacent workpieces, which is conducive to the entry of projectiles, thereby improving the shot blasting effect on the inside of the workpiece. Compared with the traditional hanging shot blasting machine, not only the shot blasting effect is improved but also the number of workpieces in a single shot blasting operation is increased, thereby improving work efficiency, and it is worthy of large-scale promotion and use.
