Description

  The present invention relates to a grating removing tool capable of safely and easily removing a grating attached to a side groove of a road.

  Conventionally, a grating is installed in a side gutter of a road in order to prevent a person or an object from falling or accumulation of garbage. However, the grating is so heavy that it is difficult to handle and cannot be easily lifted manually. When the inside of the side groove is cleaned, it must be removed using a handle exclusively for grating, for example, there are those described in Patent Documents 1 to 3.

  In Patent Document 1, an operating handle having a handle portion on one side and a pressing portion to the upper surface of the side groove lid on the other side, and a swingable hanging from an intermediate portion of the operating handle are formed on the side groove lid. There is described a groove lid attaching / detaching device including a latching body that can be inserted into the rear surface side of the side groove lid from the notch gap and has a contact portion with the rear surface of the side groove lid.

  The above-mentioned groove lid detachment tool is used as a set of two persons, each having one detachment tool and facing each other with the groove lid sandwiched from the side where the notch gap is provided. The pressing part of each detaching tool is applied to the surface of the groove lid, the latching body is inserted into the back surface side of the groove lid through the notch gap, and the contact portion of the latching body is brought into contact with the back surface of the groove lid.

  In this state, holding the handle portion of the operation handle and lifting it upward, the lifting force applied to the handle portion is applied to the hanging body with the pressing portion as a fulcrum, and the supporting portion of the hanging body as a fulcrum, It acts as a pressing force from the pressing portion to the groove lid, and the groove lid is held between the pressing portion of the operation handle and the contact portion of the latching body, and the groove lid is lifted upward.

In Patent Document 2, a central portion formed in a rod shape, an end portion formed continuously and wide at one end of the central portion, a handle portion formed continuously at the other end of the central portion, and a central portion A device for opening a lid laid on a road, the first member having a first member capable of mounting one end of the lid of the U-shaped groove and being rotatably attached to the central portion at a predetermined position. Have been described.
One end of the U-shaped groove lid is placed on the first member, and the handle portion is lifted up with the end of the lid opening machine in contact with the upper surface of the U-shaped groove lid. Open.

  Patent Document 3 describes a lifting and transferring tool for a concrete road side groove lid. An upright column, a lever lever pivotally attached to the upper end of the upright column on a horizontal axis, and a horizontal axis of the lever lever. It consists of a sandwiching arm made of an inverted V-shaped metal strip that is supported by a folded portion supported at a near end, and a support member that supports a road side groove cover is provided opposite to both ends of the sandwiching arm.

  The road side groove cover is lifted by suspending the pinching arm on the lever lever after rotating the lever in the vertical direction after making the road side groove cover supported by the opposing support member. Then, after turning the lever together with the upright support in the horizontal direction around the upright support, the road side groove cover is moved by rotating the lever in the vertical direction.

  When using the groove lid attaching / detaching device described in Patent Document 1, it is said that two people work as one set, but there are not always two or more people who remove the grating, and eventually two or more arm strengths are required. This is inconvenient when considering actual use.

  In addition, in the case of the groove lid attaching / detaching device described in Patent Document 1, the pressing portion is lifted by hitting the end portion on the lid in the case of the device for opening the lid described in Patent Document 2, but on the lid itself to be lifted. Lifting with a fulcrum is an unstable task, and it is unlikely that the force will be transmitted well.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a grating removal tool that can safely and easily remove the grating installed in the side groove.

  A grating removing tool according to the present invention is a tool for removing a grating attached to a side groove of a road, and is a fulcrum panel provided at the tip of the tool, and is rotatably attached to the fulcrum panel. An arm extending obliquely upward from the panel, and a handle provided at the rear end of the arm, an angle changing part is provided in the middle of the arm, and the angle is more than the angle from the fulcrum panel to the angle changing part. The angle from the angle changing unit to the handle is gradual, and a hook is provided that is rotatable downward from the handle side position of the angle changing unit.

  A fulcrum panel is provided at the tip of the grating removal tool, and an arm that is rotatable about the fulcrum panel is attached. This arm extends obliquely upward from the fulcrum panel, and a handle is provided at the rear end of the arm.

  In addition, there is an angle changing portion in the middle of the arm from the fulcrum panel to the handle, and the angle from the angle changing portion to the handle is gentler than the angle from the fulcrum panel to the angle changing portion.

  The arm is rotatably attached to the fulcrum panel, and the angle is changed from the middle of the arm, so that the handle can be easily moved up and down and the force can be easily applied.

  A hook that extends downward from a position near the handle of the angle changing portion is rotatably attached to the arm, and the tip end portion of the hook is hooked on the grating of the grating. The hook is pivotally attached to the arm so that the hook can move easily, and is easily attached to and detached from the grating. Further, when the handle is moved up and down, the hook is also moved up and down in conjunction with the movement.

  The shape of the hook here is not particularly limited as long as it is a shape that can be hooked on the grating of the grating.

  Moreover, it is good to adjust the height of the hook provided in the lower end part of the turnbuckle by rotating a turnbuckle by providing a turnbuckle in the upper part of the hook of a grating removal tool.

  Depending on the person who handles the grating removal tool of the present invention, there are various easy-to-use positions of the handle. Therefore, if the height of the hook can be adjusted with a tumble buckle, the height of the handle can be changed and it is easy to use.

  Furthermore, by providing a slide part that allows the hook to move from the angle changing part to the handle at the attachment position of the upper end of the hook, the position of the hook can be adjusted by sliding according to the width of the grating. . By providing this slide portion, it is possible to deal with various sizes of gratings.

  The main use of the grating removal tool of the present invention is to first install a fulcrum panel on the ground next to the grating to be removed. At this time, the arm of the grating removing tool is installed so as to intersect perpendicularly with respect to the direction in which the grating is continuous. Also, rubber for preventing misalignment is set on the installation surface of the fulcrum panel so that the fulcrum panel is stable and easy to work.

  Next, when the lower end of the hook is hooked on the grating of the grating and the handle is raised upward, the grating is easily lifted. In addition, since the arm can rotate with respect to the fulcrum panel, if the tubular object such as a roller pipe is inserted under the grating while the grating is lifted, the grating can be kept floating from the side groove. The removal tool can be removed from the grating.

  Since the grating removing tool of the present invention is configured as described above, the following effects can be obtained.

(1) The grating can be lifted lightly by one person and can be removed safely and easily.

(2) The position and height of the hook can be easily adjusted by providing the buckle and the slide part on the upper part of the hook.

(3) If a tubular object such as a roller pipe is inserted under the grating while the grating is lifted, the grating can be kept floating from the side groove, and the grating removing tool can be removed from the grating.

It is the schematic which showed one Embodiment of the grating removal tool which concerns on this invention.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this invention is not limited to embodiment shown below.

  FIG. 1 is a schematic view showing an embodiment in which a grating removing tool 1 according to the present invention is used for a grating 10.

  A fulcrum panel 2 is provided at the end of the grating removal tool 1, and an arm 3 attached to the fulcrum panel 2 is rotatable with respect to the fulcrum panel 2. The arm 3 extends obliquely upward from the fulcrum panel 2, and a handle 4 is provided at the tip of the arm 3.

  Further, the angle of the arm 3 is changed by the angle changing unit 5, and the angle from the angle changing unit 5 to the handle 4 is gentler than the angle from the fulcrum panel 2 to the angle changing unit 5.

  The arm 3 is rotatable with respect to the fulcrum panel 2, and by changing the angle from the middle of the arm 3, the handle 4 is easily grasped and moved up and down, and the arm 3 also moves smoothly.

  A turnbuckle 7 is provided so as to be pivotable downward from the angle changing portion 5 via the slide portion 8, and an L-shaped hook 6 is provided below the turnbuckle 7. Although the L-shaped hook 6 is shown here, the shape is not particularly limited as long as the grating of the grating 1 can be hooked on the tip of the hook 6.

  By attaching the turnbuckle 7 and the hook 6 via the slide portion 8, the position of the hook 6 can be slid and moved in the lateral direction. Furthermore, by providing the tumble buck 7 on the hook 6, the height of the hook 6 can be adjusted by rotating the tumble buck 7.

  Further, since the turnbuckle 7 is rotatably attached to the arm 3, the hook 6 attached under the turnbuckle 7 is easy to move and can be easily attached to and detached from the grating 10. Further, when the handle 4 is moved up and down, the arm 3, the turnbuckle 7 and the hook 6 are also moved up and down in conjunction with the movement.

  Next, an example of a procedure for cleaning the side grooves 11 will be described.

(1) Remove the fixing nut 12 of the grating 10 installed in the side groove 11 to be cleaned. At this time, when the fixing nut 12 is fixed by rust or the like, the fixing nut 12 can be easily detached by applying a lubricant before the operation. When the grating 10 is rusted or earth and sand are clogged between the grating 10 and the frame 13 and the grating 10 is fixed, the periphery of the grating 10 is cleaned with a minus driver or the like.

(2) Install the fulcrum panel 2 of the grating removal tool 1 next to the grating 10 to be removed. At this time, the grating removing tool 1 is set to the end (front side) with respect to the length L of the grating 10 and is installed in a direction in which the arms 3 perpendicularly intersect with the length L.

(3) The slide portion 8 is moved in accordance with the width of the grating 10 to adjust the horizontal position of the hook 6. Since the position of the hook 6 in the lateral direction can be adjusted by the slide portion 8, it is possible to correspond to the gratings 10 of various sizes.

(4) The turnbuckle 7 is adjusted so that the handle 4 can be easily moved up and down, and the height of the handle 4 of the grating removal tool 1 is adjusted to an appropriate height. The appropriate height is a height at which the person who handles the grating removal tool 1 can move the handle 4 up and down with a comfortable posture.

  When the turnbuckle 7 is rotated to the right, the hook 6 becomes longer and the handle 4 becomes higher. Conversely, when the turnbuckle 7 is rotated counterclockwise, the hook 6 is shortened and the handle 4 is lowered. If the position of the handle 4 is not appropriate, there is a concern that it may hurt the knees or lower back, so care must be taken.

(5) Hook 6 is hooked on the grating 10. Check that the hook 6 is securely set on the grating 10.

(6) Raise the handle 4 and lift the grating 10. When the handle 4 is lifted, it is slowly lifted upward so that the grating removing tool 1 is not displaced forward. Since the grating 10 itself is very heavy and it is dangerous to try to lift it vigorously, it should be done slowly with caution. The handle 4 is lifted to check whether it is lifted up lightly. If it is light, the process proceeds to the next operation (7).

  Here, if the grating 10 feels heavy or does not rise, it is possible that the grating 10 is still fixed to the frame 13, so the periphery of the frame 13 is cleaned again. After cleaning, the portion where the grating 10 and the frame 13 are in contact with each other is hit with a hammer or the like so that the grating 10 can move easily and be removed.

(7) When the end of the grating 10 is lifted by about 10 cm, the roller pipe is inserted between the grating 10 and the side groove 11. Here, a coro pipe has been described as an example of an object to be inserted between the grating 10 and the side groove 11, but it may be a rod having a round cross section and a thin rod shape that does not collapse even when the grating 10 is placed. .

(8) Another roller pipe is inserted in front of the roller pipe that has been inserted, and the grating 10 is placed on the two roller pipes so that the grating 10 is lifted from the side groove 11. The grating removing tool 1 is removed from the grating 10, and the grating 10 is rolled and moved on the two roller pipes. At that time, if the grating 10 is moved by pulling it directly by hand, for example, there is a risk of pinching the hand. For example, when the grating 10 is rolled using a pulling rod having an L-shaped tip. good.

(9) Clean the side groove 11 where the grating 10 is removed. Here, if one grating 10 is removed in two, the removed grating can be rolled over the adjacent grating and left as it is, which is efficient and can reduce the work load.

(10) After the gutter 11 is cleaned, the grating 10 is rolled and moved to the original position while being placed on the roller pipe.

(11) After moving to the original position, set the grating removal tool 1 again, hook the hook 6 again on the grating of the grating 10, lift the handle 4 slowly upward, lift the grating 10, and Pull out and set the grating 10 to the original position.

  By using the roller pipe, the heavy grating 10 can be easily moved without lifting. Even when extensive gutter cleaning is required, it is possible to work alone. In addition, since the heavy grating is not lifted, it is also effective for back pain countermeasures.
