Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a bridge steel structure spraying mechanism with adjustment function. Background Technology

[0002] The main demand for steel structure bridges is for bridges in the construction of transportation infrastructure such as highways, railways and urban elevated roads. At present, steel structure bridges in my country are mainly divided into several types: steel truss bridges, steel box girder bridges, steel arch bridges and steel-concrete composite beam bridges.

[0003] While most existing bridge steel structure spraying machines can perform quick and convenient spraying operations, they require manual intervention to repeatedly adjust the spraying mechanism to spray the inner side of H-shaped bridge steel structures. Furthermore, spraying wider H-shaped bridge steel structures requires operators to exert greater physical effort for adjustment. Therefore, bridge steel structure spraying machines suffer from drawbacks such as being time-consuming, labor-intensive, and having low spraying efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge steel structure spraying mechanism with adjustable function, including a movable support, a hydraulic telescopic rod welded to the surface of the movable support, an auxiliary support plate fixedly installed at the end of the hydraulic telescopic rod away from the movable support, an auxiliary support plate slidably installed on the inner side of the auxiliary support plate, a spraying bracket fixedly installed on the surface of the auxiliary support plate, a limit support plate provided on the surface of the movable support, and a limit block fixedly installed on the surface of the limit support plate.

[0006] Preferably, the limiting block is U-shaped, and an auxiliary ball is rotatably mounted on the inner side of the limiting block.

[0007] Preferably, a guide plate is fixedly installed on the surface of the auxiliary support plate, and the surface of the guide plate is slidably installed on the inner side of the auxiliary support plate.

[0008] Preferably, there are two sets of guide plates, and the two sets of guide plates are fitted with power gears on opposite sides.

[0009] Preferably, a spraying mechanism is fixedly installed on the surface of the spraying bracket, and a spraying pipe body that communicates with the spraying mechanism is fixedly installed on the surface of the auxiliary support plate.

[0010] Preferably, a drag-increasing rubber ring is bonded to the inner side of the auxiliary frame plate, and the inner side of the drag-increasing rubber ring abuts against the surface of the power gear column.

[0011] Preferably, a limiting support rod is fixedly installed on the surface of the limiting support plate, the surface of the limiting support rod is slidably installed on the inner side of the movable bracket, and an elastic component is slidably sleeved on the surface of the limiting support rod. The two ends of the elastic component are respectively fixedly installed on the surface of the limiting support plate and the surface of the movable bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The bridge steel structure spraying mechanism with adjustment function can limit the upper limit block and limit the movement of the moving support through the limit support plate, so as to ensure that the moving support and the H-shaped bridge steel structure always maintain stable movement. This ensures the reliability of the spraying mechanism at the spraying support when spraying the inner side of the H-shaped bridge steel structure of different widths. The auxiliary ball on the limit support is used to reduce the friction noise formed with the H-shaped bridge steel structure. This method ensures that the moving support can maintain stable and precise movement when the H-shaped bridge steel structure is sprayed, thus ensuring good spraying effect when spraying H-shaped bridge steel structures of different widths. It also ensures the ease of operation when spraying H-shaped bridge steel structures of different widths, reducing the disadvantages of time-consuming and laborious operation when spraying H-shaped bridge steel structures caused by manual intervention.

[0014] (2) The bridge steel structure spraying mechanism with adjustment function, after the two sets of spraying brackets reach the predetermined spraying position, no longer adjusts the power tooth column. At this time, the power tooth column forms a limit position through the frictional resistance between it and the friction-increasing rubber ring. This method ensures that the spraying bracket has the ease of operation when adjusting the inner side of H-shaped bridge steel structures of different widths, and thus ensures the convenience of spraying operation when spraying H-shaped bridge steel structures of different widths.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-6This utility model provides a technical solution: a bridge steel structure spraying mechanism with adjustable function, including a movable support 1, a hydraulic telescopic rod 2 welded to the surface of the movable support 1, an auxiliary support plate 3 fixedly installed at the end of the hydraulic telescopic rod 2 away from the movable support 1, an auxiliary support plate 4 slidably installed on the inner side of the auxiliary support plate 3, a spraying support 5 fixedly installed on the surface of the auxiliary support plate 4, a spraying mechanism 6 fixedly installed on the surface of the spraying support 5, and a spraying pipe 10 connected to the spraying mechanism 6 fixedly installed on the surface of the auxiliary support plate 4. The hydraulic telescopic rod 2, the spraying pipe 10 and the spraying mechanism 6 are all existing structures and will not be described in detail here. When the inner side of the H-shaped bridge steel structure needs to be sprayed, the spraying can at the end of the spraying pipe 10 only needs to suck the pigment into the spraying mechanism 6 for spraying. The function of the hydraulic telescopic rod 2 is to assist the spraying support 5 in adjusting the use of bridge steel structures of different heights so that the spraying mechanism 6 can be used for spraying more closely.

[0028] Furthermore, guide plates 7 are fixedly installed on the surface of the auxiliary support plate 4. The guide plates 7 are slidably installed on the inner side of the auxiliary frame plate 3. There are two sets of guide plates 7. The opposing sides of the two sets of guide plates 7 are meshed with power toothed columns 8. The inner side of the auxiliary frame plate 3 is bonded with a friction-increasing rubber ring 9. The inner side of the friction-increasing rubber ring 9 abuts against the surface of the power toothed column 8. When it is necessary to adjust the spraying bracket 5 to spray the inner side of the bridge steel structure of different widths, the operator only needs to control the power toothed column 8 to rotate inside the auxiliary frame plate 3. At this time, the power toothed column 8 will drive the two sets of guide plates 7. As the support plate 7 moves, the guide support plate 7 will drive the spraying mechanism 6 on the spraying bracket 5 to make appropriate adjustments on the inner side of the H-shaped bridge steel structure through the auxiliary support plate 4 until the two sets of spraying brackets 5 reach the predetermined spraying position and no longer adjust the power toothed column 8. At this time, the power toothed column 8 forms a limit positioning through the frictional resistance between it and the friction-increasing rubber ring 9. This method ensures that the spraying bracket 5 has the ease of operation when adjusting the inner side of the H-shaped bridge steel structure of different widths, and thus ensures the convenience of spraying operation when spraying H-shaped bridge steel structures of different widths.

[0029] Furthermore, a limiting support plate 11 is provided on the surface of the movable support 1, and a limiting support rod 12 is fixedly installed on the surface of the limiting support plate 11. The surface of the limiting support rod 12 is slidably installed on the inner side of the movable support 1, and an elastic component 13 is slidably sleeved on the surface of the limiting support rod 12. The two ends of the elastic component 13 are respectively fixedly installed on the surface of the limiting support plate 11 and the surface of the movable support 1. A limiting block 14 is fixedly installed on the surface of the limiting support plate 11. The limiting block 14 is U-shaped, and an auxiliary ball 15 is rotatably installed on the inner side of the limiting block 14.

[0030] Specifically, when spraying H-shaped bridge steel structures of different widths, the operator first raises the limiting support plate 11 on the surface of the moving support 1. At this time, the operator controls the upper limit block 14 of the limiting support plate 11 to form a docking fit with one side of the H-shaped bridge steel structure. Therefore, when the moving support 1 moves, it can be limited by the upper limit block 14 of the limiting support plate 11, ensuring that the moving support 1 and the H-shaped bridge steel structure always maintain stable movement. This ensures the reliability of the spraying mechanism 6 at the spraying support 5 when spraying the inner side of H-shaped bridge steel structures of different widths. The auxiliary ball 15 on the limiting block 14 is used to reduce the friction noise generated with the H-shaped bridge steel structure. In this way, the moving support 1 can maintain stable and precise movement when the H-shaped bridge steel structure is sprayed, thus ensuring a good spraying effect when spraying H-shaped bridge steel structures of different widths. It also ensures the ease of operation when spraying H-shaped bridge steel structures of different widths, reducing the disadvantages of time-consuming and laborious operation caused by manual intervention when spraying H-shaped bridge steel structures.

[0031] Working Principle: A bridge steel structure spraying mechanism with adjustment function. When spraying H-shaped bridge steel structures of different widths, the operator first raises the limiting support plate 11 on the surface of the moving support 1. At this time, the operator controls the upper limit support block 14 of the limiting support plate 11 to form a docking fit with one side of the H-shaped bridge steel structure. Therefore, when the moving support 1 moves, the upper limit support block 14 of the limiting support plate 11 and the limiting of the moving support 1 ensure that the moving support 1 and the H-shaped bridge steel structure always maintain stable movement. When it is necessary to adjust the spraying support 5 to spray the inner side of the bridge steel structure of different widths, the operator only needs to control the power tooth column 8 to rotate inside the auxiliary support plate 3. At this time, the power tooth column 8 will drive the two sets of guide support plates 7 to move. Therefore, the guide support plates 7 will drive the spraying mechanism 6 on the spraying support 5 to adapt to the inner side of the H-shaped bridge steel structure through the auxiliary support plate 4 until the two sets of spraying supports 5 reach the predetermined spraying position, and then the power tooth column 8 is no longer adjusted.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
