Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment technology, and in particular to an auxiliary tool for highway guardrail repair. Background Technology

[0002] Accidents on highways usually result in damage to guardrails. During maintenance, the damaged guardrails need to be removed and new guardrails need to be installed. Guardrails are usually composed of guardrail panels and posts.

[0003] When installing new guardrails, the posts are usually installed first, followed by the guardrail panels. During the installation of the posts, it is necessary to ensure that they are installed on the same straight line and with the same spacing between them. If the posts are installed off-center, not only will the guardrail panels not be able to be installed effectively, but the offset posts may also hit the pipelines under the road during the installation process, causing damage to the pipelines.

[0004] However, the location of existing columns is usually determined by workers pulling lines or finding the original installation location. This method is not accurate and is easily affected by factors such as human error or accidents that damage the site, which makes it impossible to accurately and efficiently determine the installation location of the columns, resulting in inconvenience in column installation. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tool for highway guardrail maintenance. This invention has the advantages of accurately and efficiently determining the installation position of the posts, and making post installation relatively more convenient.

[0006] The technical solution of this utility model is as follows: An auxiliary tool for highway guardrail maintenance includes a main body, a pair of retractable sleeves fitted at both ends of the main body, and three correspondingly distributed annular clamps; the annular clamps are respectively located at the middle front side of the main body and the outer ends of the sleeves, and the annular clamps on the two sleeves are mirror images of the middle of the main body as the central axis; the annular clamps are provided with an adjustment structure for adjusting their size on the outside; each annular clamp is detachably connected to the main body and sleeves through a connector; the annular clamps are available in multiple sizes; the centers of the three annular clamps are located on a horizontal straight line parallel to the main body.

[0007] In the aforementioned auxiliary tool for highway guardrail maintenance, the main body has sliding grooves at both ends, and each sleeve has a tensioning unit that passes through the sliding groove and the sleeve near the end of the main body; the tensioning unit includes an adjusting screw, a pressure block that passes through the upper part of the sleeve and is fixed to the adjusting screw, and a washer that is sleeved on the adjusting screw and located between the pressure block and the sliding groove; a nut that is screwed to the adjusting screw is fixed at the bottom of the sleeve.

[0008] In the aforementioned auxiliary tool for highway guardrail maintenance, a scale bar is provided on the upper edge of the main body, and the scale bar is distributed sequentially from the middle of the main body to both ends.

[0009] In the aforementioned auxiliary tools for highway guardrail maintenance, the connector is detachably connected to the main body and the sleeve respectively through an installation structure, and the installation structure includes at least a screw connection structure and a snap-fit ​​structure.

[0010] In the aforementioned auxiliary tools for highway guardrail maintenance, each of the sleeves is equipped with a detachable level above its outer end.

[0011] Compared with the prior art, this application sets up a main body, a pair of sleeves and three correspondingly distributed annular clamps. The three annular clamps located on the same straight line are used to fix the column, thereby ensuring that the three columns are all on the same straight line. At the same time, by adjusting the position of the sleeves and the main body, the expansion and contraction of the sleeves at both ends are the same, which ensures that the spacing between the three annular clamps is the same, and thus ensures that the spacing between the columns is the same.

[0012] By using this application, the accurate position of the post to be installed can be determined by using two normal post positions. The positioning is accurate and efficient, the post installation is more convenient, and the maintenance efficiency of the guardrail is effectively improved.

[0013] Therefore, this utility model has the advantages of accurately and efficiently determining the column installation position, and making column installation relatively more convenient. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example. An auxiliary tool for highway guardrail maintenance, comprising as follows: Figure 1 and 2As shown, the device includes a main body 1, a pair of retractable sleeves 2 fitted at both ends of the main body 1, and three correspondingly distributed annular clamps 3. The annular clamps 3 are respectively located at the middle front side of the main body 1 and the outer ends of the sleeves 2. The annular clamps 3 on the two sleeves 2 are mirror images of the middle of the main body 1 as the central axis. The annular clamps 3 are provided with an adjustment structure 31 for adjusting their size. Each annular clamp 3 is detachably connected to the main body 1 and the sleeves 2 through a connector 4. The annular clamps 3 are available in multiple sizes. The centers of the three annular clamps 3 are located on a horizontal straight line parallel to the main body 1.

[0019] The ring clamp 3 can be any commonly available adjustable clamp. Its function is to be fitted and tightened onto the column for easy positioning.

[0020] The main body 1 has sliding grooves 11 at both ends, and each sleeve 2 has a tensioning unit that passes through the sliding groove 11 and the sleeve 2 near the end of the main body 1. The tensioning unit includes an adjusting screw 5, a pressure block 51 that passes through the upper part of the sleeve 2 and is fixed to the adjusting screw 5, and a washer that is sleeved on the adjusting screw 5 and located between the pressure block 51 and the sliding groove 11. The bottom of the sleeve 2 is fixed with a nut that is screwed to the adjusting screw 5. The adjusting screw 5 passes through the sliding groove 11, and the size of the washer is larger than the sliding groove 11. The rotation of the adjusting screw 5 can drive the pressure block 51 to move up and down, thereby achieving the pressing of the main body 1.

[0021] The upper edge of the main body 1 is provided with a scale bar 12. The scale bar 12 is distributed sequentially from the middle of the main body 1 to both ends. The scale bar 12 can effectively set the extension and retraction of the sleeve 2 according to the pre-known spacing, thereby quickly positioning the position.

[0022] The connector 4 is detachably connected to the main body 1 and the sleeve 2 respectively through the mounting structure, and the mounting structure includes at least a screw connection structure and a snap-fit ​​structure.

[0023] Each of the sleeves 2 is provided with a detachable level 6 above its outer end. The level 6 is used to ensure that the application is in a horizontal state during use, thereby improving positioning accuracy.

[0024] Furthermore, the sleeve 2 can be linked with the main body 1 through a gear structure to achieve synchronous expansion and contraction. A common synchronous symmetrical movement mechanism can be adopted. For example, a horizontally rotatable gear can be set in the middle of the main body 1, and the two sleeves 2 can be respectively equipped with symmetrical racks that pass through the inside of the main body 1 and mesh with the gear from both sides. In this way, the expansion and contraction of the sleeve 2 is corresponding to the meshing of the gear and rack, and the expansion and contraction of the sleeves 2 at both ends are consistent.

[0025] Furthermore, this application can be applied not only to guardrail maintenance, but also to guardrail installation during road construction. It can effectively determine the installation position of the posts to be installed, thereby improving installation accuracy and efficiency.
