Description

Technical Field

[0001] The utility model relates to the technical field of anti-skid plates for shot blasting machines, in particular to an anti-skid plate for shot blasting machines. Background Art

[0002] Shot blasting machines use high-speed rotating shot blasters to project steel shots and other projectiles onto the surface of a workpiece. The impact and friction remove scale, rust, oil, and old coatings from the workpiece's surface, while simultaneously roughening the surface and enhancing coating adhesion. This process not only improves the cleanliness and surface quality of the workpiece, but also lays a solid foundation for subsequent surface treatments such as painting and electroplating.

[0003] In the prior art, the shot blasting machine needs to perform the shot blasting work for a long time during operation, which will cause the entire shot blasting machine to vibrate for a long time. Therefore, an anti-skid plate is set at the position of the bottom support foot of the shot blasting machine to prevent slipping, thereby preventing the shot blasting machine from vibrating for a long time and causing the position to shift sideways, thereby affecting the shot blasting cleaning work of the shot blasting machine. The commonly used anti-skid plate is generally made of rubber, and a number of protrusions are set at the bottom of the rubber plate to improve the anti-skid ability. However, the rubber anti-skid plate wears out quickly during use. Once friction occurs with the ground, the anti-skid particles will be worn out, thereby greatly reducing the anti-skid effect and shortening the service life of the anti-skid plate. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-skid plate for a shot blasting machine, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A skid plate for a shot blasting machine comprises a main board, a plurality of through holes being provided on the top side of the main board, an expansion slot being provided on the inner side wall in the middle portion of the through hole, a top rod and a bottom rod being slidably mounted at the upper and lower openings of the through hole, two limit plates being slidably connected in the expansion slot, the two limit plates being fixedly connected to the opposite ends of the top rod and the bottom rod, respectively, and a spring being fixedly connected between the two limit plates.

[0007] In a preferred example, the present invention can be further configured as follows: the bottom end of the bottom rod is conical, and the bottom end of the bottom rod extends below the bottom side of the main board.

[0008] In a preferred example, the present invention can be further configured as follows: a plurality of arc-shaped grooves are opened on the bottom side of the main board, and a plurality of the through holes are located in the arc-shaped grooves.

[0009] In a preferred example, the present invention can be further configured as follows: a plurality of transverse grooves are provided on the bottom side of the main board, and each transverse groove is located between two corresponding adjacent bottom bars.

[0010] In a preferred example, the present invention can be further configured as follows: a plurality of rectangular grooves are provided on the top side of the main board, and the top side of the main board between two adjacent rectangular grooves is arranged in a trapezoidal shape.

[0011] In summary, the present invention has at least one of the following beneficial technical effects:

[0012] 1. This anti-skid plate for a shot blasting machine can increase the pressure between the main board and the ground by lowering the bottom rod and raising the top rod during use, thereby improving the stability of the main board when placed on the ground, as well as the pressure between the support legs of the shot blasting machine and the main board, thereby increasing the friction between the main board and the support legs, thereby improving the stability between the support legs and the main board when the shot blasting machine is working, so that the main board can be stabilized on the ground, and avoiding damage to the main board and the bottom rod due to friction on the ground;

[0013] 2. This anti-skid plate for a shot blasting machine has transverse grooves that form a number of bumps on the bottom of the main plate, further increasing the roughness of the bottom side of the main plate, thereby increasing the friction between the main plate and the ground, thereby preventing the main plate from shifting due to vibration of the shot blasting machine;

[0014] 3. The anti-skid plate for a shot blasting machine has a rectangular groove that increases the roughness of the top of the mainboard, thereby cooperating with the resistance of the ejector rod to further increase the friction between the support foot and the top side of the mainboard, thereby improving the stability of the support foot when the shot blasting machine is working.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Example:

[0023] Reference Figures 1-4 The utility model discloses an anti-skid plate for a shot blasting machine, comprising a main board 1, a plurality of through holes 2 are opened on the top side of the main board 1, an expansion slot 3 is opened on the inner wall of the middle part of the through hole 2, and a top rod 4 and a bottom rod 5 are slidably installed at the upper and lower openings of the through hole 2, respectively. Two limit plates 6 are slidably connected in the expansion slot 3, and the two limit plates 6 are fixedly connected to the opposite ends of the top rod 4 and the bottom rod 5, respectively, and a spring 7 is fixedly connected between the two limit plates 6.

[0024] In this embodiment, when in use, the main board 1 is placed at the position of the bottom support feet when the shot blasting machine is installed, wherein the number of main boards 1 required corresponds to the number of support feet, and then the shot blasting machine is placed on the corresponding number of main boards 1. At this time, the main board 1 will be pressed down, and the bottom rod 5 will move upward from the bottom of the through hole 2, and push the corresponding limit plate 6 to slide in the expansion slot 3. At the same time, the corresponding limit plate 6 and the top rod 4 will be pushed upward by the spring 7, wherein the top rod 4 located directly below the support foot of the shot blasting machine will press against the support foot, and the top rod 4 located on the side of the support foot will slide out to the top of the through hole 2, so that the peripheral side wall of the top rod 4 fits with the corresponding support side.

[0025] It should be noted that the position of each through hole 2 needs to be adapted to the width, length or diameter of the corresponding support foot, so that in addition to the ejector pin 4 pressed into the through hole 2, the ejector pin 4 located on the side of the support foot can be moved above the through hole 2 so that the peripheral side wall of the ejector pin 4 can fit the support foot. Therefore, the arrangement of the through holes 2 needs to adapt to the shape of the bottom of the support foot.

[0026] Then the bottom of the supporting foot is in contact with the corresponding top rod 4, and the side walls of a number of top rods 4 are in contact with the sides of the supporting foot, which can limit the supporting foot. The material of the top rod 4 can be made of stainless steel or aluminum alloy to improve rigidity and stability. The bottom rod 5 will exert a certain stress on the ground due to the influence of the spring 7, thereby increasing the friction between the supporting foot and the main board 1 as well as the friction between the ground and the main board 1, thereby achieving an anti-slip effect and avoiding the problem of reduced anti-slip performance due to friction.

[0027] In a further preferred embodiment of the present invention, Figure 1 As shown, the bottom end of the bottom rod 5 is conical, and the bottom end of the bottom rod 5 extends to below the bottom side of the main board 1.

[0028] In this embodiment, the bottom end of the bottom rod 5 is conically set, so that when the bottom rod 5 exerts stress on the ground, it can increase the roughness of the bottom of the main board 1, thereby further increasing the friction and reducing the phenomenon of the main board 1 moving due to vibration of the shot blasting machine. The bottom end of the bottom rod 5 extends to the bottom of the main board 1 to provide a moving space for the movement of the bottom rod 5, and at the same time facilitates the movement of the top rod 4.

[0029] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a number of arc-shaped grooves 8 are formed on the bottom side of the main board 1 , and a number of the through holes 2 are located in the arc-shaped grooves 8 .

[0030] In this embodiment, the arc-shaped groove 8 can increase the roughness of the bottom side of the main board 1, thereby increasing the friction between the main board 1 and the ground, and improving the stability of the main board 1 during use.

[0031] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a number of transverse grooves 9 are provided on the bottom side of the main board 1 , and each transverse groove 9 is located between two corresponding adjacent bottom bars 5 .

[0032] In this embodiment, the transverse grooves 9 are provided so that a number of bumps are formed on the bottom of the main board 1, further increasing the roughness of the bottom side of the main board 1, thereby increasing the friction between the main board 1 and the ground, thereby avoiding the position displacement of the main board 1 due to the vibration of the shot blasting machine.

[0033] In a further preferred embodiment of the present invention, Figure 1 As shown, a number of rectangular grooves 10 are opened on the top side of the main board 1, and the top side of the main board 1 between two adjacent rectangular grooves 10 is arranged in a trapezoidal shape.

[0034] In this embodiment, the rectangular groove 10 is provided to increase the roughness of the top of the main board 1, thereby cooperating with the resistance of the top rod 4 to further increase the friction between the support foot and the top side of the main board 1, thereby improving the stability of the support foot when the shot blasting machine is working.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
