[0020] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and are not to be construed as limitations on the utility model. On the contrary, the embodiments of the utility model include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims. The surface grinding device for the guardrail plate of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 2 As shown, the guardrail plate surface grinding device of the embodiment of the utility model may include a sliding rod 1, multiple connecting mechanisms 2, multiple moving blocks 3, multiple installation mechanisms 4, multiple grinding mechanisms 5 and multiple arc grinding mechanisms 6.

[0022] The connecting mechanism 2 is installed on both sides of the sliding rod 1 , a plurality of moving blocks 3 are installed on the sliding rod 1 , and the mounting mechanism 4 is arranged at the bottom of the moving blocks 3 .

[0023] It can be understood that the connecting structure is installed on a supporting component (not shown in the figure). Since this component is common knowledge in the field, it will not be described here. It is used to install and place the grinding device. The shock-absorbing spring 23 is used to achieve a shock-absorbing effect when grinding the guardrail.

[0024] It should be noted that, in this embodiment, the moving block 3 can be a locking slider, which can be adjusted according to the relative distance between the lowest points of the corrugated guardrail plates A.

[0025] The grinding mechanism 5 is mounted on the mounting mechanism 4 , and the arc grinding mechanism 6 is mounted on the grinding mechanism 5 . The arc grinding mechanism 6 may include a grinding arc 61 , a connecting column 62 , a rack 63 and two cross bars 64 .

[0026] The two cross bars 64 are installed at the two ends of the two grinding arcs 61 , and the cross bars 64 are arranged on both sides of the grinding mechanism 5 .

[0027] It should be noted that the cross bar 64 is used to support the grinding arc 61, and the grinding arc 61 is close to the side of the corrugated guardrail plate A to grind the side wall of the corrugated guardrail plate A.

[0028] The connecting column 62 is installed at the end of the grinding arc 61 , and two racks 63 are respectively arranged on the two connecting columns 62 , and the two racks 63 can be connected to each other.

[0029] In one embodiment of the present invention, Figure 2 As shown, a pull rod mechanism 7 is provided on both sides of the grinding roller 51 , and the pull rod mechanism 7 may include two connecting strips 71 and a compression spring 72 .

[0030] Two connecting bars 71 are installed on both sides of the grinding roller 51 . A bar groove 711 is provided inside the connecting bar 71 . A compression spring 72 is arranged inside the bar groove 711 . The compression spring 72 is connected to the cross bar 64 .

[0031] It should be noted that the cross bar 64 is connected to the compression spring 72 , and the extension length of the cross bar 64 inside the groove 711 can be adjusted, so as to adapt to arcs of different diameters.

[0032] Specifically, when facing guardrails with different curvatures, by adjusting the relationship between the racks 63 on the two connecting columns 62, the cross bar 64 can be extended to different lengths under the engagement of the racks 63. At the same time, due to the limitation of the groove 711, the cross bar 64 can be prevented from tilting, thereby preventing the grinding arc 61 from shifting.

[0033] Specifically, when the guardrail plate needs to be polished, the guardrail plate is placed at the bottom of the sliding rod 1, and then the distance between the moving blocks 3 is adjusted so that the multiple moving blocks 3 can be consistent with the spacing of the arcs on the corrugated guardrail plate A. Afterwards, the two connecting columns 62 are moved relative to each other, so that the racks 63 on the two connecting columns 62 are engaged to different positions, and the distance between the two grinding arcs 61 is adjusted to better fit the curvature side of the guardrail plate.

[0034] Afterwards, turn on the drive motor 52, and the drive motor 52 can drive the grinding roller 51 in the middle to grind the lowest part of the curvature of the guardrail plate. At the same time, when the drive motor 52 rotates, the drive motor 52 will drive the grinding arc 61 to rotate, so that the grinding arc 61 can grind the side of the curvature of the guardrail plate.

[0035] As a result, the deep curvature of the bottom of the corrugated guardrail and the internal sides can be polished simultaneously, reducing the frequency of step-by-step operations and secondary manual intervention, greatly improving the overall polishing efficiency and shortening the construction period.

[0036] It should be noted that, in this embodiment, the driving motor 52 is a rotary motor. At the same time, the relevant staff can set an arc grinding mechanism 6 on the top of the grinding roller 51 according to the grinding needs, and the two arc grinding mechanisms 6 cooperate with each other to achieve the grinding of the inner wall of the guardrail plate.

[0037] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the grinding mechanism 5 may include a grinding roller 51 and a driving motor 52 .

[0038] The driving motor 52 is installed in the middle of the grinding roller 51 . A mounting column groove 511 is provided on the grinding roller 51 . Two connecting columns 62 are installed inside the mounting column groove 511 . The driving motor 52 is embedded inside the mounting mechanism 4 .

[0039] It should be noted that when the driving motor 52 rotates, it can drive the grinding roller 51 to rotate, and the grinding roller 51 thereby drives the grinding arc 61 to rotate, thereby achieving grinding of multiple locations of the guardrail plate.

[0040] In one embodiment of the present invention, Figure 2 As shown, the mounting mechanism 4 may include a first support rod 41 , a second support rod 42 and an extension rod 43 .

[0041] The two second support rods 42 are installed horizontally, the first support rod 41 is installed between the second support rods 42 , the extension rod 43 is installed on the first support rod 41 at the top, and the extension rod 43 is connected to the moving block 3 .

[0042] It can be understood that the grinding roller 51 can be suspended by the provided extension rod 43 , so as to facilitate the connection of the grinding roller 51 .

[0043] In one embodiment of the present invention, Figure 1 As shown, the connecting mechanism 2 may include a connecting rod 21 , a connecting block 22 and a shock absorbing spring 23 .

[0044] The connecting rod 21 is installed on both sides of the sliding rod 1 , the connecting block 22 is installed on the top of the connecting rod 21 , and the shock absorbing spring 23 is installed on the connecting rod 21 .

[0045] It should be noted that the provided shock-absorbing spring 23 can offset the vibration generated by the grinding roller 51 during grinding, thereby ensuring the stability of grinding.

[0046] In summary, the guardrail surface grinding device of the embodiment of the utility model can synchronously grind the deep arc of the bottom of the corrugated guardrail and the inner sides, reducing the frequency of step-by-step operations and secondary manual intervention, greatly improving the overall grinding efficiency and shortening the construction period.
