Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel structure processing, specifically a sand blasting device for steel structure polishing. BACKGROUND

[0002] Steel structure is easy to be affected by oxidation and corrosion in the process of use, thereby rust and oxide layer can be formed on the surface, and the service life of the steel structure is reduced, and at this time, the rust and oxide layer can be removed by polishing to restore the steel structure surface to the original state, and the polishing efficiency is higher, and the sand blasting gun is used to spray the sand on the surface of the steel structure, the rust, scale, oil stains and other impurities on the surface of the steel structure are removed through the impact and friction of the sand, so that the subsequent surface treatment work such as painting and spraying can be carried out.

[0003] At present, when rust removal is carried out by sand blasting, the operator needs to hold the air pipe of the sand blasting gun, but because the power of compressed air is large, the operator needs to hold the air pipe at all times, and if the air pipe is not held firmly, the swing range of the air pipe can be large, which not only affects the polishing efficiency of the steel structure, but also can cause the sand in the air pipe to injure the operator; therefore, the sand blasting device for steel structure polishing is proposed for the above problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0023] This application discloses a sandblasting device for grinding steel structures. (Refer to...) Figure 1 A sandblasting device for grinding steel structures includes an air pipe 1, a stabilizing component 2 on the surface of the air pipe 1, a shielding component 3 on the surface of the stabilizing component 2, and a supporting component 4 on the surface of the air pipe 1.

[0024] Reference Figure 1 - Figure 2The stabilizing component 2 includes a connecting sleeve 21 fixedly mounted on the surface of the trachea 1. A grip plate 22 is fixedly mounted on the bottom of the connecting sleeve 21, and a handle 23 is fixedly mounted on the top of the connecting sleeve 21. A friction block 24 is fixedly mounted on the side of the handle 23 near the connecting sleeve 21, and a ring 25 is fixedly mounted on the left side of the handle 23. The grip plate 22 is made of rubber to facilitate the operator to lift the grip plate 22 and thus lift the trachea 1. The handle 23 is three-quarters of a ring. Multiple friction blocks 24 are evenly distributed on the surface of the handle 23. The friction blocks 24 can improve... The friction between the operator's hand and the handle 23 allows for a more stable grip on the handle 23. The shielding assembly 3 includes a telescopic plate 31 fixedly installed on the surface of the connecting sleeve 21. A pin 32 is fixedly installed on the right side of the top of the telescopic plate 31. The telescopic plate 31 is composed of multiple relatively sliding shielding nets. The pin 32 is fixedly installed on the surface of the uppermost shielding net. The pin 32 and the insert ring 25 are adapted to be inserted. After the multiple shielding nets are pulled out and the pin 32 is inserted into the inside of the insert ring 25, the telescopic plate 31 can prevent accidentally ejected sand from being ejected backward.

[0025] Reference Figure 3 - Figure 4 The support assembly 4 includes a guide rail 41 fixedly installed on the top of the air tube 1. A threaded rod 42 is rotatably connected inside the guide rail 41. A slider 43 is threadedly connected to the surface of the threaded rod 42. A support plate 44 is fixedly installed on the top of the slider 43. Locking blocks 45 are fixedly installed on both the front and rear sides of the surface of the air tube 1. An elastic rope 46 is fixedly connected inside the two locking blocks 45. The right side of the threaded rod 42 extends to the outside of the guide rail 41. The slider 43 is slidably connected inside the guide rail 41. When the threaded rod 42 is rotated, it will drive the threaded slider 43 to slide inside the guide rail 41. At this time, the slider 43 will drive the support plate 44 to move accordingly, so that the operator can place his elbow on the top of the support plate 44 and avoid his arm from being suspended in the air for a long time and feeling excessive fatigue.

[0026] Working principle: After the operator connects the air hose 1 to the drive end of the sandblasting device, the operator holds the handle 23 with the palm facing upwards. The friction block 24 at the bottom of the handle 23 increases the friction between the handle and the palm, allowing the operator to hold the handle 23 more stably. Then, the operator stretches the telescopic plate 31, so that the pin 32 at the top of the telescopic plate 31 is inserted into the inside of the insert ring 25. Then, the operator rotates the threaded rod 42, which drives the threaded slider 43 to slide inside the guide rail 41. The slider 43 then moves the support plate 44 until it is moved to the appropriate position. Then, the operator places the elbow joint of the arm on top of the support plate 44, which supports the elbow joint. Then, the operator loosens the connection between an elastic rope 46 and the locking block 45, wraps the elastic rope 46 around the arm, and then inserts the elastic rope 46 into the inside of the locking block 45. The elastic rope 46 then restricts the joint of the arm, completing the preparation work.

[0027] The operator then drives the sandblasting device, which uses compressed air to spray sand onto the steel structure surface through air pipe 1 for polishing.
