DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.
[0032] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts are within the scope of protection of the present application.
[0033] In order to facilitate the understanding of the relevant skilled person, the process of how to perform sandblasting on the inner wall of a square steel pipe in the prior art will be described in more detail below.
[0034] Firstly, i.e. sandblasting preparation work, including checking the steel pipe (to ensure that the steel pipe without serious deformation, cracks and other defects), cleaning the steel pipe (cleaning the steel pipe wall on the sundries, moisture, etc.), steel pipe fixing (the steel pipe is placed on the fixed structure, to ensure that the steel pipe is fixed firmly). Then, i.e. the selection of sandblasting material (according to the steel pipe material and the inner wall dirt condition, select the appropriate sandblasting material, such as quartz sand, steel sand, glass bead, etc.). Then, the equipment debugging (first check the sandblasting equipment, to ensure that the sandblasting machine, pressure tank, spray gun and other equipment are intact; then according to the sandblasting material and environmental conditions, adjust the sandblasting pressure). Then, the sandblasting operation (the operator holds the spray gun, and stretches it into the square steel pipe inner wall to carry out the sandblasting operation). After the sandblasting operation, check the cleanliness and roughness of the steel pipe inner wall, to ensure that the specified requirements are met. And in the process of sandblasting, the operator should wear protective clothing, protective glasses, mask and other personal protective articles.
[0035] However, due to the small radial size and large axial size of the square steel pipe, the operator has high difficulty in controlling the spray gun to spray the inner wall, which leads to low sandblasting efficiency, and it is difficult to ensure that all the inner wall parts of the square steel pipe are completely and uniformly sandblasted, which leads to poor sandblasting effect.
[0036] Therefore, the present application provides a new solution, i.e. the steel pipe sandblasting equipment of the present application, which can not only be well adapted to the size of the square steel pipe, reduce the operation difficulty, effectively ensure the sandblasting efficiency, but also ensure that all parts of the inner wall of the square steel pipe are completely and uniformly sandblasted, which is beneficial to improve the sandblasting effect.
[0037] The technical solutions of the present application are described in detail below in combination with the drawings.
[0038] Example 1
[0039] As Figures 1 to 5As shown, the embodiment provides a steel pipe sand blasting device 100, which is suitable for the inner wall sand blasting operation of a square steel pipe 200, and includes a base plate 1, a placing assembly 2, a sand blasting assembly 3 and a control assembly 4. The base plate 1 is arranged along the horizontal direction. The placing assembly 2 is arranged on the base plate 1 and is used for placing the square steel pipe 200. The sand blasting assembly 3 is arranged on the base plate 1, and the sand blasting assembly 3 includes a first driving device 31, a second driving device 32, a rotary sealing mechanism 33, a sand inlet pipe 34, a main pipe 35, three branch pipes 36 and three sand blasting heads 37. The output end of the first driving device 31 is connected with the second driving device 32, so as to drive the second driving device 32 to move along the axial direction of the square steel pipe 200. The output end of the second driving device 32 is connected with the rotary sealing mechanism 33, so as to drive the rotary sealing mechanism 33 to rotate. One end of the sand inlet pipe 34 is communicated with the rotary sealing mechanism 33, and the other end of the sand inlet pipe 34 is used for being communicated with a sand blasting machine. One end of the main pipe 35 is communicated with the rotary sealing mechanism 33, and the other end of the main pipe 35 is respectively communicated with the three branch pipes 36. The three sand blasting heads 37 are respectively installed at the ends of the three branch pipes 36 away from the main pipe 35. The axial directions of the three branch pipes 36 are perpendicular to the axial direction of the main pipe 35, and the three branch pipes 36 are uniformly and spacedly arranged along the circumferential direction of the main pipe 35. The control assembly 4 is arranged on the base plate 1 and is electrically connected with the first driving device 31 and the second driving device 32.
[0040] For the convenience of relevant technical personnel to understand, the working principle / process of the above technical solution will be described first.
[0041] When the sand blasting operation on the inner wall of the square steel pipe 200 is needed, the square steel pipe 200 can be first installed on the placing assembly 2, and then the first driving device 31 and the second driving device 32 are used to move along the axial direction of the square steel pipe 200, so that the sand blasting area of the sand blasting head 37 corresponds to one end of the square steel pipe 200. Then the sand blasting machine can be started, and the sand blasting machine supplies sand blasting materials to the sand blasting head 37 through the sand inlet pipe 34, the rotary sealing mechanism 33, the main pipe 35 and the branch pipe 36. The sand blasting head 37 performs sand blasting on the inner wall of the square steel pipe 200. At the same time, the second driving device 32 is started to drive the sand blasting head 37 to rotate through the rotary sealing mechanism 33, so as to realize the sand blasting of one circle of the inner wall of the square steel pipe 200. Subsequently, after the sand blasting of the circle is completed, the first driving device 31 is used to control the sand blasting head 37 to move along the axial direction of the square steel pipe 200, so as to perform the sand blasting operation of the next circle of the inner wall of the square steel pipe 200. In this way, the sand blasting operation of the whole area of the inner wall of the square steel pipe 200 can be realized.
[0042] Firstly, the steel pipe sand blasting equipment 100 sprays the inner wall of the square steel pipe 200, without manually holding the sand blasting head 37 or manually adjusting the position and sand blasting area of the sand blasting head 37, which can effectively adapt to the square steel pipe 200, effectively reduce the operation difficulty, and effectively ensure the sand blasting efficiency.
[0043] Secondly, the steel pipe sand blasting equipment 100 sprays the inner wall of the square steel pipe 200, which can comprehensively and uniformly spray the inner wall of the square steel pipe 200, effectively avoid the problem of uneven sand blasting, and effectively ensure the sand blasting effect of the inner wall of the square steel pipe 200.
[0044] In this embodiment, it should be noted that first, the three branch pipes 36 and the three sand blasting heads 37 are uniformly and spacedly arranged along the circumference of the main pipeline 35, so that the reaction forces of the three sand blasting heads 37 on the branch pipes 36 during the sand blasting process are counteracted, the force balance of the sand blasting assembly 3 during the sand blasting process is ensured, the position stability of the sand blasting head 37 during the sand blasting process is effectively ensured, the spatial interference between the sand blasting head 37 and the inner wall of the square steel pipe 200 is avoided, and the structural safety of the square steel pipe 200 and the smooth progress of the sand blasting operation are effectively ensured.
[0045] Secondly, the rotating sealing mechanism 33 is a device for sealing connection between the rotating part (main pipeline 35) and the fixed part (first driving device 31 and sand inlet pipe 34), mainly for preventing sand leakage and allowing the rotating part to rotate relative to the fixed part. Since the rotating sealing mechanism 33 has been widely used in various pumps, valves, mixers, rotary joints and other equipment or devices, the specific structure and working principle thereof will not be described here.
[0046] In the prior art, when the inner wall of the square steel pipe 200 is sprayed, the sand blasting gun also applies a certain force to the square steel pipe 200 during sand blasting. In order to ensure the position stability of the square steel pipe 200 during sand blasting, the square steel pipe 200 is generally fixed by using a binding structure or a fixed installation structure. However, it is obvious that these binding structures or fixed installation structures will increase the time consumption of the sand blasting operation to a certain extent (mainly the need to fix the steel pipe before sand blasting and release the fixation of the steel pipe after sand blasting is completed), and reduce the efficiency of the sand blasting operation.
[0047] Therefore, in an embodiment of the present application, as shown in Figure 4As shown, the placing assembly 2 of the present application can include a first mounting plate 21, a second mounting plate 22 and a placing plate 23, the placing plate 23 is formed in a V-shaped structure, the placing plate 23 includes a first plate body 231 and a second plate body 232 connected perpendicularly to each other, and the included angle between the first plate body 231 and the base plate 1 is 45°, one end of the first mounting plate 21 is connected to the end of the first plate body 231 away from the second plate body 232, the other end of the first mounting plate 21 is connected to the base plate 1, one end of the second mounting plate 22 is connected to the end of the second plate body 232 away from the first plate body 231, and the other end of the second mounting plate 22 is connected to the base plate 1.
[0048] In this way, the placing plate 23 arranged in this way can limit the square steel pipe 200, so that the square steel pipe 200 can still effectively ensure its position stability during the sand blasting process without binding or fixing, that is, the time-consuming of the sand blasting operation can be effectively reduced, and the efficiency of the sand blasting operation can be improved.
[0049] In an embodiment of the present application, as shown in Figure 4 The placing plate 23 of the present application can also be formed in a Y-shaped structure, the placing plate 23 includes a first plate body 231 and a second plate body 232 connected perpendicularly to each other, and a third plate body 233 connected to the first plate body 231 and the second plate body 232 respectively, the end of the third plate body 233 away from the first plate body 231 is connected to the base plate 1, and the first mounting plate 21, the second mounting plate 22 and the third plate body 233 are arranged parallel to each other.
[0050] In this way, the structural strength and position stability of the placing plate 23 can be further enhanced, and the position stability and state stability of the square steel pipe 200 during the sand blasting operation can be further improved.
[0051] In an embodiment of the present application, the second driving device 32 of the present application can be configured to drive the rotation sealing mechanism 33 to rotate at a frequency of 0.1 revolutions / minute to 2 revolutions / minute, so as to adapt to the sand blasting needs of the inner wall of the square steel pipe 200 in different actual situations.

[0053] In this way, when the square steel pipe 200 with different radial sizes is encountered, the relative height position of the first driving device 31 can be adjusted by the third driving device 38, and then the relative height position of the sand blasting head 37 is adjusted to adapt to the square steel pipe 200 with different radial sizes, so that the universality of the steel pipe sand blasting equipment 100 is effectively improved.

[0055] In this way, when the square steel pipe 200 with different radial sizes is encountered, the relative height position of the first driving device 31 can be adjusted by the third driving device 38, and then the relative height position of the sand blasting head 37 is adjusted to adapt to the square steel pipe 200 with different radial sizes, so that the universality of the steel pipe sand blasting equipment 100 is effectively improved.

[0057] In this way, the alignment circle line 351 combined with the alignment assembly 5 in the above-mentioned embodiment can quickly and accurately adjust the relative position of the sand blasting assembly 3 to adapt to the inner wall sand blasting needs of the square steel pipe 200.
