Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail installation, specifically to a movable guardrail installation auxiliary device. Background Technology
[0002] In highway construction, the installation of corrugated crash barriers is still predominantly done manually. First, transport vehicles deliver the barriers to the construction site for unloading. Then, multiple workers lift them and bolt them onto the guardrail posts. The guardrails are large and heavy, requiring manual labor for both unloading and installation, resulting in extremely high labor intensity and failing to effectively reduce labor costs. Therefore, there is an urgent need for specialized equipment that reduces manual labor and labor intensity, while simultaneously enabling the mechanization and automation of guardrail transport and installation. Thus, researching a movable guardrail installation auxiliary device is essential. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a movable guardrail installation auxiliary device.
[0004] This utility model is achieved through the following technical solution:
[0005] A movable guardrail installation auxiliary device includes a mobile trolley, a lower column is installed on the upper part of the mobile trolley, the top of the lower column is connected and fixed to an upper column that can adjust the height through a locking assembly, and a bracket for supporting the guardrail is installed on the top of the upper column, with a limit support assembly provided on the inner side of the bracket.
[0006] Further optionally, the locking assembly includes an open sleeve connected to the top of the lower column, an upper column extending into the lower column is provided inside the open sleeve, a locking rod is connected to the opening of the open sleeve, the outside of the locking rod is hinged to one end of the wristband, and the other end of the wristband is hinged to the side of the open sleeve.
[0007] Alternatively, a cam connecting block is provided at the hinge joint between the wristband and the locking rod. The cam connecting block is fixed by hinge to the pin, and a washer fitted onto the locking rod is provided on the outside of the cam connecting block.
[0008] Further optionally, the limiting support assembly includes a limiting plate placed in the placement slot inside the bracket, the lower two sides of the placement slot being fixed to the lower two ends of the bracket by L-shaped blocks, and the top of the limiting plate having several strip grooves.
[0009] Alternatively, the two ends of the limiting plate may extend outwards from the outer bracket.
[0010] Further optional features include a hand-held frame and a toolbox for storing tools mounted on the mobile cart.
[0011] Compared with existing technologies, the advantages of this utility model are: the utility model has a simple structure, is easy to use, and has good stability; its top bracket can be raised and lowered to meet the installation requirements of different guardrail heights; it is easy to use, and the placement, transportation, installation, and removal are simple and quick, greatly improving the installation efficiency of corrugated plates.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0017] like Figure 1 As shown, a movable guardrail installation auxiliary device includes a mobile trolley 1. The mobile trolley 1 is equipped with four universal wheels 2 at its lower part for easy movement and steering. The mobile trolley 1 is equipped with a lower column 5 at its upper part. The lower column 5 is made of round tube and can be sleeved on an upper column 12. The top of the lower column 5 is connected and fixed to the upper column 12, which is adjustable in height, through a locking assembly. The top of the upper column 12 is equipped with a bracket 13 for supporting the guardrail. The bracket 13 is provided with a limit support assembly on its inner side.
[0018] like Figure 2 As shown, the locking assembly includes an open clamp 6 connected to the top of the lower column 5. The open clamp 6 can open and close to fix and clamp the upper column 12 and release it. An upper column 12 extending into the lower column 5 is provided inside the open clamp 6. A locking rod 8 is connected to the opening of the open clamp 6. The locking rod 8 is hinged to one end of the wristband 7, and the other end of the wristband 7 is hinged to the side of the open clamp 6.
[0019] like Figure 2 As shown, a cam connecting block 9 is provided at the hinge of the wristband 7 and the locking rod 8. The cam connecting block 9 is fixed to the pin 10 by hinge. A gasket 11 is provided on the outside of the cam connecting block 9 and sleeved on the locking rod 8. The metal gasket 11 can prevent the cam connecting block 9 from rubbing against the open sleeve 6.
[0020] like Figure 3 As shown, the limiting support assembly includes a limiting plate 15 placed inside the placement groove 14 of the bracket 13. The bracket 13 has a "J" shaped cross-section and mainly serves to support the placement of the guardrail. The lower two sides of the placement groove 14 are fixed to the lower ends of the bracket 13 by L-shaped locking blocks 16. The top of the limiting plate 15 has several strip grooves 17. The strip grooves 17 can support and limit multiple corrugated plates, preventing the corrugated plates from shaking inside the bracket 13 and ensuring the stability of the movement of the corrugated plates.
[0021] like Figure 3 As shown, the two ends of the limiting plate 15 extend outward from the bracket 13. This outward extension ensures better support and prevents a seesaw effect at both ends of the corrugated plate.
[0022] The mobile cart 1 is equipped with a pusher 4 and a toolbox 3 for storing tools. When the pusher 4 is fixed to the mobile cart 1, a triangular frame is welded to make it more stable. The grip area is covered with a layer of green rubber to increase the grip friction and protect the palm. A rectangular toolbox 3 with a lid is welded to the middle of the pusher 4 for easy storage of tools such as wrenches.
[0023] The implementation principle of the movable guardrail installation auxiliary device in this application is as follows:
[0024] When installing the corrugated guardrail, first adjust the height of the bracket 13 according to the height of the guardrail installation. When adjusting, move the bracket 13 up and operate the hand ring 7 of the locking assembly to press down. The hand ring 7 presses the opening sleeve 6 through the cam connecting block 9 to achieve the fixed locking of the opening sleeve 6 to the upper post 12.
[0025] Next, the workers moved the corrugated guardrail panels from the transport vehicle onto the bracket 13 of the mobile trolley 1. When placing them, the bottom of multiple corrugated guardrail panels can be locked into the strip groove 17 of the corresponding limiting plate 15, and their tops can be tilted against the side of the bracket 13 to achieve stable placement of the corrugated guardrail panels.
[0026] After placement, the worker operates the pusher 4 to push the moving trolley 1 to move the corrugated guardrail to the side of the corresponding guardrail post for installation. After installation, the worker operates the pull-lock buckle assembly's hand ring 7. The hand ring 7 drives the cam connecting block 9 to the minimum radius end, releasing the pressure on the gasket 11. In this way, the opening sleeve 6 is in a loose state, and the upper post 12 changes from a tight state to a loose state. Under the action of gravity, it quickly detaches from the already installed guardrail and then installs the next guardrail. This installation is quick and convenient, saving time and effort and greatly improving the efficiency of installation.
[0027] 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
