Description

Technical Field

[0001] The utility model relates to the field of protection for loading and unloading of shot blasting machines, and particularly to a protection structure for loading and unloading of a hook-type shot blasting machine. Background Technique

[0002] A shot blasting machine is a commonly used device for surface hardening and surface treatment of workpieces in industries such as casting, metallurgy, and machining. The shot media can be various specifications of sand, silicon carbide particles, small steel balls, etc. A hook-type shot blasting machine is a type of shot blasting machine. During loading and unloading, the workpiece is usually hung on a workpiece storage rack. The storage rack is provided with lifting lugs, and then the hook of an electric hoist is hooked to the lifting lug. Finally, the workpiece is sent into the shot blasting machine by the electric hoist. However, during the process of lifting the workpiece storage rack and sending the workpiece into the shot blasting machine, the situation where the workpiece collides with the feed inlet of the shot blasting machine and the top of the workpiece storage rack hits the top plate of the shot blasting chamber may occur, which is likely to cause varying degrees of damage to the workpiece and the shot blasting chamber. The Chinese utility model patent with the application number 202223474427.4 discloses an automatic loading and unloading mechanism for a shot blasting machine, which can be adaptively adjusted according to the actual specifications of castings, is simple to operate, has high protection performance, improves the processing efficiency of castings by the shot blasting machine, and is convenient to use.

[0003] The above-mentioned automatic loading and unloading mechanism for a shot blasting machine can be adaptively adjusted according to castings. However, when the workpiece enters the shot blasting chamber through the feed inlet, it will still bump into the feed inlet, and there is no protection structure for the top plate of the shot blasting chamber, so the problem that the workpiece collides with the feed inlet of the shot blasting machine and the top of the workpiece storage rack hits the top plate of the shot blasting chamber cannot be effectively solved.

Cross bars are respectively fixedly arranged on the left and right sides of the fixing member. The ends of the cross bars are fixedly connected to the middle positions of the inner sides of the vertical bars. A rubber block is fixedly arranged at the top of the vertical bar. Hanging ears are respectively fixedly arranged on the outer sides of the lower half of the vertical bar. A protection member is detachably hooked on the hanging ears.

[0006] As a preferred technical solution, the fixing member includes arc-shaped fixing plates arranged oppositely. One side of the fixing plate is hinged. Fixing blocks that are parallel to each other are respectively fixedly arranged at the other ends of the fixing plates. A bolt is commonly passed through the fixing blocks, and a locking nut is arranged at the protruding end of the bolt.

[0007] As a preferred technical solution, a plurality of conical rubber protrusions are further provided on the inner surface of the fixing plate, and the whole is evenly spaced.

[0008] As a preferred technical solution, the protective member includes a vertical rubber plate, the top of the rubber plate is provided with a bent portion inward, and a through hole for cooperating with the hanging ear is provided at the center position of the bent portion.

[0009] As a preferred technical solution, magnetic strips that attract and cooperate with each other are provided at the bottom of the rubber plate.

[0010] As a preferred technical solution, outwardly convex arc-shaped handles are vertically and spacedly fixed on the outer side surface of the rubber plate.
