AI Technical Summary
In existing technologies, it is difficult to remove guardrail posts, especially because they are squeezed by roadbed filler, requiring a large external pulling force, and the wire ropes are prone to breakage or loosening, posing a safety hazard.
The structure uses a combination of hollow steel pipes, steel plates, U-shaped rings, and high-strength bolts. The hollow steel pipes are inserted into the column, and the high-strength bolts are used to drill holes and connect steel wire ropes and U-shaped rings, which are then used in conjunction with an excavator to remove the column.
It enables the rapid and safe removal of guardrail posts, avoiding safety risks such as wire rope breakage and posts being thrown out.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway construction technology, and in particular to a tool for quickly removing existing guardrail posts. Background Technology
[0002] The existing highways have limited width, but with the improvement of living standards, the traffic volume is increasing, requiring the widening of the existing highways. In order not to affect the passage of existing vehicles, temporary guardrails will be installed on the existing roads to separate the traffic flow. Guardrails are installed on curved sections or high embankment sections. The design requires the removal of the existing guardrails (the guardrails mainly consist of three parts: guardrail posts, anti-blocking blocks, and guardrail panels, which are connected by bolts) and the installation of new guardrails. The difficulty in removing the existing guardrails is the removal of the guardrail posts, because the guardrail posts have been squeezed by the roadbed filling material, and a large external pulling force is required to remove the guardrail posts.
[0003] The original method for dismantling the column involved threading a steel wire rope through the hole in the column, securing it, and then using a crane to lift it. However, this method was prone to the wire breaking or coming loose, causing the column to collapse. This method was quite dangerous. Furthermore, because the steel wire has a certain degree of elasticity, when pulling the column out of the ground, the inertia could cause it to swing out of the ground, which was also dangerous. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick removal tool for existing guardrail posts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tool for quickly removing existing guardrail posts, comprising a hollow steel pipe, a steel plate fixedly connected to the middle of the hollow steel pipe, a U-shaped ring fixedly connected to the top of the steel plate by bolts, a hole one provided at the bottom of the steel plate, and holes two provided around the hollow steel pipe.
[0006] As a further description of the above technical solution:
[0007] High-strength bolts are installed in the middle of holes one and two.
[0008] As a further description of the above technical solution:
[0009] The hollow steel pipe has two holes, which are arranged opposite each other.
[0010] As a further description of the above technical solution:
[0011] A column is installed on one side of the hollow steel pipe.
[0012] This utility model has the following beneficial effects:
[0013] In this invention, a hollow steel pipe is placed inside the guardrail post. A high-strength bolt (or round steel) is first passed through the existing bolt holes in the guardrail post, and then through the opening in the hollow steel pipe (and the lower hole in the steel plate). Excavator bucket teeth are hung on a wire rope, and a U-shaped ring is passed through it. The excavator raises its boom, thus removing the guardrail post. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Reference Figure 1-2 One embodiment of this utility model is a tool for quickly removing existing guardrail posts, including a hollow steel pipe 1, a steel plate 2 fixedly connected to the middle of the hollow steel pipe 1, a U-shaped ring 3 fixedly connected to the top of the steel plate 2 by bolts, a hole 4 at the bottom of the steel plate 2, and holes 5 on all four sides of the hollow steel pipe 1.
[0021] High-strength bolts 6 are installed in the middle of holes 4 and 5. Hollow steel pipe 1 has two holes, which are set opposite each other. Steel plate 2 has two holes 4 (upper hole and lower hole). The upper hole is used to pass through U-shaped ring 3, and the lower hole is used to pass through high-strength bolts 6 (or round steel). A column 7 is installed on one side of hollow steel pipe 1.
[0022] Working principle: The hollow steel pipe 1 is inserted into the guardrail post 7. The high-strength bolt 6 (or round steel) is first passed through the existing bolt holes of the guardrail post 7, and then through the opening in the hollow steel pipe 1 (and the lower hole of the steel plate 2). The excavator bucket teeth are hung on the wire rope, and the U-shaped ring 3 is passed through it. The excavator raises its boom, thus removing the guardrail post 7.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
