Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a hook type guard plate. Background Art

[0002] The shot blasting machine uses a high-speed rotating shot blaster to eject the projectile at high speed, so that the projectile has a certain kinetic energy. The high-speed linear motion projectile directly impacts the surface of the workpiece to completely remove the rust, oxide scale and other covering layers on the surface of the workpiece. There is a cleaning chamber inside the shot blasting machine, and a guard plate is usually installed inside the cleaning chamber to protect the internal structure of the shot blasting machine from being easily damaged.

[0003] In the prior art, the authorized patent with application number CN202122034872.8 discloses a shot blasting machine cleaning chamber inner guard plate, including a guard plate, an internal threaded ring, a protective cover and a cast-in nut; the internal threaded ring is embedded in the guard plate, and the cast-in nut is installed on the guard plate inside the internal threaded ring, and the bottom end of the protective cover is connected to the inner thread of the internal threaded ring and other components.

[0004] Since the above scheme fixes the guard plate to the inner wall of the shot blasting chamber by means of threaded bolts and other components when in use, the guard plate needs to be screwed with the bolted components multiple times during assembly and disassembly, which affects the efficiency of assembly and disassembly and replacement of the guard plate. Moreover, the above scheme utilizes the elastic layer to fill the gap when the guard plate is spliced. Under the impact of shot blasting, the damage rate of the elastic layer is greater than the damage rate of the guard plate. Therefore, during the use of the guard plate, the shot blasting can pass through the gap when the guard plate is spliced ​​and cause damage to the inner wall of the shot blasting chamber, thus affecting the protective effect of the guard plate. Based on this, the present application proposes a hook-type guard plate. Utility Model Content

[0005] The utility model provides a hook-type guard plate, which solves the problem proposed in the above background technology that when the guard plate is connected to the inner wall of the shot blasting chamber by a component with a thread, it is inconvenient to disassemble and assemble the guard plate; the shot can pass through the gap when the guard plate is spliced ​​to cause damage to the inner wall of the shot blasting chamber, thereby affecting the protective effect of the guard plate.

[0006] The utility model provides the following technical solutions: a hook-type guard plate, wherein the guard plate body is hung on the inner wall of the shot blasting chamber by a hook, a hanging groove adapted to the hook is provided on the inner wall of the shot blasting chamber, the guard plate body is translated along the hanging groove by the hook, the hook comprises an upper hook connected to the top end of the back side of the guard plate body and a lower hook fixedly connected to the bottom end of the back side of the guard plate body, and a lower hook is provided below the middle of two adjacent upper hooks;

[0007] A splicing groove is provided on the outer side of one end of the guard plate body, and another splicing groove is provided on the inner side of the other end of the guard plate body. When the guard plate bodies are spliced, a Z-shaped splicing seam is formed at the splicing point of two adjacent guard plate bodies.

[0008] Preferably, the size of the upper hook is the same as that of the lower hook, and both the upper hook and the lower hook are L-shaped.

[0009] Preferably, the thickness of one end of the upper hook connected to the guard plate body is greater than the thickness of the other end.

[0010] Preferably, the thickness of the splicing groove is half of the thickness of the guard plate body, and the two splicing grooves are symmetrically arranged on the guard plate body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The hook-type guard plate is provided with an upper hook and a lower hook, and the guard plate is connected with the inner wall of the shot blasting machine through the hook, so that the guard plate can be quickly disassembled and assembled.

[0013] 2. The hook-type guard plate forms a splicing area at the joint of two adjacent guard plates through the setting of the splicing groove, so that the splicing seams between the two guard plates are staggered, thereby avoiding the impact of shot blasting on the inner wall of the shot blasting machine through the splicing seams of the guard plates.

[0022] The following will be combined with the drawings in 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 in 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.

[0023] The utility model provides a hook-type guard plate, comprising a guard plate body 1, the guard plate body 1 is hung on the inner wall of the shot blasting chamber by a hook, a hanging groove adapted to the hook is provided on the inner wall of the shot blasting chamber, and the guard plate body 1 is translated along the hanging groove by the hook. Through the setting of the hook, the guard plate body 1 can quickly enter and exit the inner wall of the shot blasting chamber by translation, thereby making the guard plate quickly disassembled and assembled, and facilitating the replacement of the guard plate.

[0024] The hooks include an upper hook 2 connected to the top of the back of the guard plate body 1 and a lower hook 3 fixedly connected to the bottom of the back of the guard plate body 1, and a lower hook 3 is provided below the middle of two adjacent upper hooks 2, and the number of upper hooks 2 provided at the top of the back of the guard plate body 1 exceeds the number of lower hooks 3. The provision of the upper hooks 2 and the lower hooks 3 can improve the stability of the guard plate during installation, and facilitate the hooks to support the guard plate.

[0025] The size of the upper hook 2 is the same as that of the lower hook 3. Both the upper hook 2 and the lower hook 3 are L-shaped, and the thickness of one end of the upper hook 2 connected to the guard plate body 1 is greater than the thickness of the other end. This arrangement can improve the reliability of the connection between the upper hook 2 or the lower hook 3 and the guard plate body 1.

[0026] A splicing groove 4 is provided on the outer side of one end of the guard plate body 1, and another splicing groove 4 is provided on the inner side of the other end of the guard plate body 1. The two splicing grooves 4 are symmetrically arranged on the guard plate body 1. Through the arrangement of the splicing grooves 4, the gap formed between two adjacent guard plates during the splicing process of the guard plate is Z-shaped, such as Figure 5 As shown, it can avoid that the gap generated when the shot blasting passes through the guard plate splicing affects the inner wall of the shot blasting room.

[0027] The thickness of the splicing groove 4 is half of the thickness of the guard plate body 1 . This arrangement facilitates the splicing of the guard plate and can extend the service life of the guard plate body 1 .

[0028] In some embodiments of the present application, an upper hook 2 is fixed on both sides of the top of the back side of the guard plate body 1, and a lower hook 3 is fixed in the middle of the bottom end of the back side of the guard plate body 1, and the width of the joint seam is 10 cm; and in this embodiment, the length of the guard plate body 1 is 360 cm, the width of the guard plate body 1 is 350 cm, the distance between the back of the upper hook 2 and the front of the guard plate body 1 is 52 cm, the distance between the end of the lower hook 3 connected to the guard plate body 1 and the bottom of the guard plate body 1 is 40 cm, and the distance between the upper hook 2 and the lower hook 3 is 245 cm.

[0029] To sum up: when the hook-type guard plate is used, the staff first sets a hanging groove adapted to the upper hook 2 on the inner wall of the shot blasting chamber, and then aligns the upper hook 2 and the lower hook 3 with the installation groove and inserts them to achieve the installation of the guard plate.
