[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the railway maintenance machinery monitoring screen support of an embodiment of the utility model includes a base 1, an adjustment component 2 and a bearing plate 3, the bearing plate 3 is used to install the display screen, and the adjustment component 2 includes an adjustment disk 21 connected to the bearing plate 3 and an adjustment shaft 22 connected to the base 1. Figure 2 and Figure 3 As shown, the adjusting disk 21 is provided with four arc holes 211, and the four arc holes 211 are distributed on the same circumference. A limiting nail 4 is provided in the arc hole 211, and one end of the limiting nail 4 is connected to the bearing plate 3. A connecting bracket 5 is provided on the base 1, and the connecting bracket 5 is U-shaped. The adjusting shaft 22 passes through the connecting bracket 5. Figure 4 As shown, both ends of the adjusting shaft 22 are fixed on the connecting bracket 5 by means of first fastening nuts 24 .

[0026] Since the adjusting disk 21 is provided with a plurality of arc holes 211, and the plurality of arc holes 211 are distributed on the same circumference, the bearing plate 3 can rotate on the adjusting disk 21. The limiting nail 4 can slide in the arc hole 211, which plays a guiding and stabilizing role on the one hand, so that the bearing plate 3 can rotate smoothly, and on the other hand, it prevents the bearing plate 3 and the adjusting disk 21 from separating. By adjusting the tightness of the limiting nail 4, the rotation damping of the bearing plate 3 can be adjusted, so that the bearing plate 3 can be rotated to the required angle and kept fixed. The adjusting shaft 22 can rotate on the connecting bracket 5, so that the bearing plate 3 and the base 1 can be adjusted at a larger angle, and the first fastening nut 24 can lock the adjusting shaft 22 on the connecting bracket 5. Through the rotation adjustment of the bearing plate 3 and the rotation adjustment of the adjusting shaft 22, the railway maintenance machinery monitoring screen bracket of the utility model can be adjusted at different angles to meet the installation needs of different railway maintenance machinery monitoring screens.

[0027] like Figure 1 and Figure 5 As shown, the adjustment assembly 2 also includes an adjustment bracket 23, and the adjustment bracket 23 includes a V-shaped plate 231 and a flat plate 232. The adjustment shaft 22 passes through the flat plate 232 and the flat plate 232 is located in the middle of the adjustment shaft 22. One end of the flat plate 232 is fixedly connected to a surface of one side of the V-shaped plate 231, and the other side of the V-shaped plate 231 is connected to a side of the adjustment disk 21 away from the bearing plate 3. The railway maintenance machinery will generate a certain degree of vibration when working, and the V-shaped plate 231 can undergo a certain degree of elastic deformation under the action of external force, thereby playing a shock-absorbing and buffering effect, reducing the vibration of the display screen installed on the bearing plate 3, and playing a certain degree of protection effect.

[0028] like Figure 2 As shown, the connecting bracket 5 includes a backing plate 51 and two side plates 52 spaced apart from each other on the backing plate 51. Figure 2 and Figure 4 As shown, the adjustment shaft 22 includes a shaft body 221, a limiting ring 222 and a connecting portion 223. The limiting ring 222 is sleeved on both ends of the shaft body 221, and the connecting portion 223 is arranged on the end surface of the shaft body 221 and passes through the side plate 52. The end of the limiting ring 222 away from the shaft body 221 is in contact with the connecting bracket 5, and the first fastening nut 24 is connected to the connecting portion 223 and is located on the side of the side plate 52 away from the limiting ring 222. When the first fastening nut 24 is tightened, the side plate 52 will press the limiting ring 222 so that the two fit closely, and the friction between the two is used to fix the adjustment shaft 22. In order to increase friction, the contact surface between the limiting ring 222 and the side plate 52 is roughened. When the angle needs to be adjusted, it is only necessary to loosen the first fastening nut 24, which is very easy to operate.

[0029] like Figure 1 and Figure 2As shown, the adjusting disk 21 is provided with a stud 25, and the adjusting bracket 23 is fixed on the adjusting disk 21 by a second fastening nut 26. By screwing the second fastening nut 26, the fastening and disassembly of the adjusting bracket 23 can be achieved, and the operation is very simple.

[0030] like Figure 5 As shown, the V-shaped plate 231 includes a first connecting plate 2311 and a second connecting plate 2312 arranged at an angle, and one end of the stud 25 passes through the first connecting plate 2311 and is located between the first connecting plate 2311 and the second connecting plate 2312. The stud 25 and the second fastening nut 26 fully utilize the space inside the V-shaped plate 231, making the overall structure of the adjustment assembly 2 more compact.

[0031] In this embodiment, the central angle of the arc hole 211 is not less than 30 degrees. The four arc holes 211 are all located on the same circumference, and the central angle of each arc hole 211 corresponding to the arc length is not less than 30 degrees, so that the bearing plate 3 can rotate at a larger angle and can be adjusted to a larger extent to meet actual needs.

[0032] like Figure 1 As shown, the base 1 includes a bottom plate 11 and a column 12 arranged on the bottom plate 11, and the connecting bracket 5 is arranged at one end of the column 12 away from the bottom plate 11. The length of the column 12 is selected according to actual needs, and the bottom plate 11 has a large area, which can firmly fix the railway maintenance machinery monitoring screen bracket as a whole.

[0033] like Figure 6 As shown, further, the column 12 includes a column 121, and the two ends of the column 121 are respectively provided with a first connection seat 122 and a second connection seat 123, and the column 121 is a hollow structure, the first connection seat 122 is connected to the bottom plate 11, and the second connection seat 123 is connected to the connection bracket 5. The hollow column 121 has a light weight, which helps to reduce the overall weight of the railway maintenance machinery monitoring screen bracket for easy installation. Since the column 121 adopts a hollow structure, in order to make the column 12 more firmly connected to the bottom plate 11 and the connection bracket 5, the two ends of the column 121 are respectively provided with a first connection seat 122 and a second connection seat 123.

[0034] Specifically, the first connection seat 122 and the second connection seat 123 are both threadedly connected to the column 121 to achieve the purpose of quick assembly and disassembly.

[0035] like Figure 6 As shown, a plurality of reinforcing ribs 124 are provided on the surface of the column 121, and the reinforcing ribs 124 are provided along the length direction of the column 121. By providing the reinforcing ribs 124, the structural strength can be enhanced, so that the hollow column 121 is not easy to bend and deform.

[0036] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
