Description

  The present invention relates to a lane separator removal tool used when removing a lane separator installed in a central separator, a lane change unit, or the like.

  On highways and ordinary roads, for example, a lane separator is installed in the central zone every 12 m (5 m in special cases), and is also installed in a lane narrowing section, a chain attachment / detachment site, an interchange, and the like.

  An example of the structure of the lane separator is shown in FIG. The lane separator 10 includes a pedestal 11 having a bolt 12 screwed into a nut 20 embedded in a road surface, and a main body pipe 13 erected on the pedestal 11. A reflection sheet 14 is attached to the main body pipe 13. It has been. The lane separator 10 having such a configuration is installed on the road at predetermined intervals (see Patent Document 1).

  The lane separator installed on the road surface is formed of a flexible plastic material such as polyurethane so that the lane separator is not damaged even if the vehicle collides and can be restored.

  The main body pipe 13 and the like formed of such a plastic material is deteriorated due to deterioration of the material or the color of the reflection sheet 14 in a severe environment such as sunlight, wind and rain, and snowfall. When it comes, replacement is necessary. In the case of emergency, lane markings are replaced at the time of accident recovery work and maintenance work. However, for example, more than 10 years have passed since the opening of the expressway. In the road-blocking work, it has become possible to replace several hundred units, and there is a demand for an efficient removal device.

  As described above, this type of lane separator 10 is bolted to a nut 20 embedded in the road surface of the road, and is attached to the back surface of the pedestal 11 with an adhesive so that it does not come off due to loosening or roll on the road surface. In many cases, the road surface is firmly fixed.

  Conventionally, when removing the lane separator 10 that is fixed between the back surface of the pedestal 11 and the road surface with an adhesive and is bolted to an embedded nut, a tool 20 with two claws as shown in FIG. 6 is used. The claw portion 21 at the tip of the lane separation mark 10 is provided in the base 11 of the lane separation mark 10 and mounted in the hole 11a. The tool 20 is turned to loosen the bolt 12 at the lower end of the main body pipe 13, and the lane separation mark 10 is removed.

  However, such work has to be done with a bowed posture, and the replacement work spans many lane markings, which has been a harsh labor for workers. Furthermore, since roads must be regulated during replacement work, traffic will be hindered if replacement work is prolonged.

  In order to solve such a problem, the applicant of the present application previously disclosed a lane separation mark replacement tool that can significantly reduce the burden on the worker and shorten the work time in Patent Document 2.

  That is, a sheath pipe that is longer than the length of the main body pipe 13 shown in FIG. 5 and that can be mounted on the outer periphery of the main body pipe 13, and a pin that projects from the lower end of the sheath pipe and fits into the hole 11a of the base 11 The rotating machine coupling part provided on the upper part of the sheath tube is provided.

Japanese Patent Laying-Open No. 2006-161382 (see FIG. 6) Utility Model Registration No. 3161291 (see FIGS. 1 to 3)

  The conventional claw tool shown in FIG. 6 is turned by hand in a crouched state, so that it is inefficient to replace it at night and is burdened on the waist. In addition, since the lane separators have different hole intervals depending on the manufacturer, it is necessary to prepare each instrument, and the work becomes complicated.

  Moreover, since the tool disclosed in Patent Document 2 is used by coupling an impact wrench to a rotating machine coupling part provided at the upper part of the sheath tube, the operation is simple, but the impact wrench and the drive are driven. Power generators are required, and there are difficulties in economic efficiency and mobility.

  Therefore, the present invention provides a lane marking removal tool that can be operated in a standing position, not a burdensome operation of bending down, and can be used with a simple operation without using electricity. The purpose is to provide.

In order to solve the above problems, the lane marking removal tool of the present invention is provided with a shaft that can be inserted into a tool insertion hole provided in a pedestal of the lane marking at the lower end of the pole that can be held, and at the bottom of the pole. A kick plate for fixing an arm perpendicular to the axis and generating a moment for rotating the pole around the axis when the arm is kicked forward by a shoe of an operator at the longitudinal end of the arm And a moment transmission bar that contacts the lower part of the lane separator is provided at the end of the arm opposite to the kick plate.
In the present invention, the shaft at the lower end of the pole is inserted into the tool insertion hole of the pedestal of the lane separation mark, and the upper portion of the pole is held by the worker, and the kick plate is kicked forward by the worker's shoes to move the shaft. A moment that rotates the pole as a center is generated. The pole has a moment transmission bar in the opposite direction to the kick plate, and the rotational moment acting on the moment transmission bar is transmitted to the lane marking. The bolt shown in FIG. 5 is loosened by receiving the rotational force at two points with the contact portion with the moment transmission bar. Thereby, the worker can perform the operation of supporting the pole with his hand and kicking the kick board with his foot in a standing posture.
By connecting a handle having a hand-held portion to the upper portion of the pole in a rotatable manner, it is possible to suppress the movement of the pole that is lifted by the reaction when the kick plate is kicked by the handle.

According to the present invention, the shaft that can be inserted into the tool insertion hole provided in the pedestal of the lane separator is provided at the lower end of the pole that can be held, and the arm that is orthogonal to the axis is fixed to the lower portion of the pole. At the end in the longitudinal direction, a kick plate is provided for generating a moment for rotating the pole around the axis when kicked forward by a worker's shoe, and the end of the arm opposite to the kick plate is provided. By providing a moment transmission bar that contacts the lower part of the lane marking, it is possible to operate in a standing position rather than a burdensome posture such as bending over. Therefore, it is possible to provide a lane marking removal tool that can be used with a simple operation.
