Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device for removing a gutter lid of a road gutter.

[0002]

[Prior art]

 Conventionally, there is a jig that applies the lever principle as a device for removing the gutter lid of a road gutter.

[0003]

[Issues to be solved by the device]

 The jig applying the lever principle described in the prior art is unstable and difficult to set, and the distance between the load point and the fulcrum is large, so the overall size is large and a lot of manpower is required to raise the groove lid.

[0004]

[Means for Solving the Problems]

 As shown in FIGS. 1, 2 and 3, the device according to the present invention allows the groove lid to be easily lifted by a hydraulic cylinder on a stable main body supported by four wheels on both upper surfaces of the side groove. is there.

Then, the device holding the groove lid is pulled out by pulling the handle toward the front side.

[0006]

[Action]

 With the hook raised to the upper limit, place both wheels on both upper surfaces of the gutter, align the hook position with the maintenance hole on the groove lid, loosen the valve of the pump, and lower the hook into the maintenance hole.

Then, the hook is moved inward and the butterfly bolt is tightened. Next, tighten the valve of the pump, lift the groove lid held by the hook with the hydraulic cylinder, and pull the handle toward you.

[0008]

【Example】

 Examples will be described with reference to the drawings. In FIG. 4, with the hydraulic cylinder 5 raised to the upper limit, the device is placed on the ground and the wheels 2 are placed so as to be located on both upper surfaces of the side groove D.

As shown in FIG. 5, the position of the hook 7 is aligned with the maintenance hole of the groove lid C, the valve of the pump 6 is loosened, and the hook 7 is lowered into the maintenance hole.

As shown in FIG. 6, the hook 7 is moved inward and the butterfly bolt 8 is tightened.

As shown in FIG. 7, the hook 7 is raised up to the upper limit by the hydraulic cylinder 5 with the groove cover C held up, and the entire apparatus is pulled out to the handle 4 side.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

As described in claim 1, according to the width of the side groove, both arms can be pulled out and the wheel spacing can be changed as shown in FIG. Therefore, the removal work can be performed up to the groove cover width of 380 mm to 620 mm.

As described in claim 2, by changing the interval between the hooks, it is possible to work the groove lid lengths of 500 mm and 600 mm.

As described in claim 3, since the hydraulic cylinder is installed, and the groove lid is removed by moving it up and down with a manual pump, the gap is filled with sand or soil, so that it can be easily removed even if there is some resistance. Can be done.

A groove lid having a thickness of 60 mm to 120 mm can be removed.

Since the arm and hook of the wheel are securely fixed with the thumbscrew, it is possible to work safely.

This device can be divided into two parts as shown in FIGS. 9 and 10 by removing the two bolts 10, so that one person can load and unload it on a truck or the like. Assembly can be done in a short time by tightening two bolts 10.

The JIS standard groove lids that can be removed with this device are shown in (Table 1) and (Table 2).
