Description

Technical Field

[0001] This utility model relates to the field of auxiliary device technology, and in particular to an auxiliary device for shot blasting pretreatment of concrete surface. Background Technology

[0002] Shot blasting pretreatment of concrete surfaces is a process that uses high-speed steel shot (or other wear-resistant particles) to mechanically treat the concrete surface. One of its main purposes includes the following: surface cleaning and purification, removal of laitance and impurities. After concrete is poured, a laitance layer often exists on the surface. Shot blasting can effectively remove the laitance, expose the solid aggregate, and remove contaminants such as oil, dust, and release agent residue, ensuring that the subsequent coating adheres firmly to the base layer. The existing shot blasting pretreatment equipment mainly consists of ground shot blasting machines.

[0003] In the prior art, when using a ground shot blasting machine for shot blasting pretreatment of concrete surfaces, the dust from the existing shot blasting machine is usually connected to another dust treatment device through a pipe, which drags on the ground, making it inconvenient to move the shot blasting machine. Therefore, this utility model proposes an auxiliary device for shot blasting pretreatment of concrete surfaces to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for shot blasting pretreatment of concrete surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for shot blasting pretreatment of concrete surfaces includes a shot blasting machine. A dust discharge pipe is connected to the outer circular wall of the dust discharge port of the shot blasting machine via a pipe clamp. The device also includes a support and moving assembly for moving the dust discharge pipe. The support and moving assembly is located on one side of the shot blasting machine and includes two support plates, both located on one side of the shot blasting machine. Two hinged feet are fixedly installed on the top surface of each support plate. A rotating ring frame is rotatably connected to the outside of each hinged foot. A plurality of arc-shaped placement plates are provided on the top surface of the shot blasting machine, spaced apart. Two support wings are fixedly installed on both sides of the outer surfaces of each arc-shaped placement plate. The support wings are fixedly installed to the top surface of the support plates. A plurality of casters are fixedly installed on the bottom surface of each support plate. A limiting mechanism is provided on the top surface of the support plate for limiting the rotation ring frame.

[0007] As a further embodiment of this utility model, the limiting mechanism includes: two limiting plates, both of which are fixedly installed on the top surface of the support plate; a connecting plate is provided on the bottom surface of the rotating ring frame; an elastic plate is provided on one side of the connecting plate; the elastic plate is engaged with the limiting plate; a lower pressure plate is fixedly installed on one side of the elastic plate; and a guide groove is provided on one side of the elastic plate.

[0008] As a further embodiment of this utility model, the top surface of the elastic plate is provided with a limiting protrusion, and the inner top surface of the limiting plate is provided with a limiting groove, the limiting groove being movably sleeved with the limiting protrusion.

[0009] As a further embodiment of this utility model, a latex elastic band is fixedly installed on one side of the connecting plate, and the latex elastic band is fixedly installed on the inner circular wall surface of the rotating ring frame.

[0010] As a further embodiment of this utility model, the rotating ring frame, the connecting plate, the elastic plate, and the reinforcing rib are manufactured using an integral molding process.

[0011] As a further embodiment of this utility model, a number of side ribs are provided on the outer side of the connection between the support wing and the arc-shaped placement plate to strengthen the connection.

[0012] As a further embodiment of this utility model, a latex gasket is fixedly installed on the top surface of the arc-shaped placement plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the shot blasting machine, dust exhaust pipe, support plate, hinged feet, rotating ring frame, support wings, and limiting plate in coordination, the shot blasting pretreatment of the ground can be assisted. During use, the shot blasting machine moves the dust exhaust pipe, which in turn moves the support plate via the casters at the bottom. This allows the support plate to support the dust exhaust pipe, preventing damage caused by friction on the ground. This effectively assists in the shot blasting pretreatment process and facilitates the installation and removal of dust exhaust pipes of different sizes and diameters, making it convenient and practical.

[0025] Reference Figures 1-6An auxiliary device for shot blasting pretreatment of concrete surfaces includes a shot blasting machine 1. A dust discharge pipe 2 is connected to the outer circular wall of the dust discharge port of the shot blasting machine 1 via a pipe clamp. The device also includes a support and moving assembly for moving the dust discharge pipe 2. The support and moving assembly is located on one side of the shot blasting machine 1 and includes two support plates 3, both located on one side of the shot blasting machine 1. Two hinged feet 4 are fixedly installed on the top surface of the support plates 3. A rotating ring frame 5 is rotatably connected to the outside of the hinged feet 4. Several arc-shaped placement plates 8 are provided on the top surface of the shot blasting machine 1, spaced apart. Two support wings 6 are fixedly installed on both sides of the outer surface of each arc-shaped placement plate 8, and the support wings 6 are fixedly installed to the top surface of the support plates 3. Several casters 9 are fixedly installed on the bottom surface of the support plates 3. A limiting mechanism is provided on the top surface of the support plates 3 to limit the rotation ring frame 5.

[0026] In this embodiment, the limiting mechanism includes: two limiting plates 7, both of which are fixedly installed on the top surface of the support plate 3; a connecting plate 11 is provided on the bottom surface of the rotating ring frame 5; an elastic plate 10 is provided on one side of the connecting plate 11; the elastic plate 10 is engaged with the limiting plate 7; a lower pressure plate 13 is fixedly installed on one side of the elastic plate 10; a guide groove 19 is provided on one side of the elastic plate 10; a limiting protrusion 15 is provided on the top surface of the elastic plate 10; a limiting groove 14 is provided on the inner top surface of the limiting plate 7; the limiting groove 14 is movably sleeved with the limiting protrusion 15; and a latex elastic band 12 is fixedly installed on one side of the connecting plate 11; the latex elastic band 12 is fixedly installed on the inner circular wall surface of the rotating ring frame 5.

[0027] In this embodiment, the rotating ring frame 5, the connecting plate 11, the elastic plate 10 and the reinforcing rib 16 are made by an integral molding process. Several side ribs 17 are provided on the outer side of the connection between the support wing 6 and the arc-shaped placement plate 8 to strengthen the connection. A latex gasket 18 is fixedly installed on the top surface of the arc-shaped placement plate 8.

[0028] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0029] When the user needs to use the shot blasting machine 1 to pre-treat the concrete surface, the user can manually press down the pressure plate 13 to rotate and drive the elastic plate 10 to bend elastically. This causes the limiting protrusion 15 to move out of the limiting groove 14 and the elastic plate 10 to move out of the limiting plate 7. As a result, the limiting plate 7 no longer limits the rotating ring frame 5, and the rotating ring frame 5 can be flipped over.

[0030] Then, the dust exhaust pipe 2 is placed inside the arc-shaped placement plate 8. The arc-shaped placement plate 8 supports the dust exhaust pipe 2. Next, the rotating ring frame 5 is rotated, causing the internal latex elastic band 12 to rotate. The internal latex elastic band 12 presses down and fixes the dust exhaust pipe 2. The latex elastic band 12 has sufficient elasticity (the resistance model is selected according to the actual situation) and can be extended and retracted, thus fixing dust exhaust pipes 2 of different diameters. Then, the elastic plate 10 is engaged with the limiting plate 7, so that the elastic plate 10... The dust exhaust pipe 2 is fixed inside the limiting groove 14 by entering the limiting groove 14. The latex gasket 18 increases the friction between the dust exhaust pipe 2 and the arc-shaped placement plate 8. When the shot blasting machine 1 performs shot blasting pretreatment on the ground, it drives the dust exhaust pipe 2 to move. The dust exhaust pipe 2 drives the support plate 3 to move through the universal wheels 9 at the bottom, so that the support plate 3 can support the dust exhaust pipe 2 and avoid damage caused by friction on the ground. This effectively assists in the shot blasting pretreatment work and is quite practical.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
