JPH08170315A - Extracting instrument of damaged residual deliater (phonetic) - Google Patents

Abstract

PURPOSE: To extract a residual damaged deliater (phonetic) as it is, and to shorten workhours by inserting an extracting instrument into the deliater (phonetic) by tilting in the longitudinal dirction, catching inner circumferences at both ends in the longitudinal direction by a pawl and drawing the deliater (phonetic). CONSTITUTION: When a residual deliater (phonetic) D is extracted, non-return fittings 3 are inserted first, and the non-return fittings 3 are pulled up by a level 1 through a chain 5. The non-return fittings 3 are inclined so that the connecting section 23 side of the chain 5 is lowered and inserted at that time, and a base end pawl 17 is brought into press-contact particularly with the inner circumferential surface of the deliater (phonetic) D and a nose pawl 19 is brought into press contact by the reaction of the press-contact. Consequently, the state of retaining, in which the deliater (phonetic) D is pulled up, is ensured. Since the retaining state is strengthened with the increase of the extraction resistance of the deliater (phonetic) D, the release of the retaining state is obstructed, and the deliater (phonetic) D can be drawn out surely so far as required force is applied to the lever 1. When the deliater (phonetic) D is difficult to be extracted at a time, the length of the chain 5 is adjusted at a place where the chain 5 is hooked to a hook 11, and the deliater (phonetic) D is pulled out several times while shortening the length of the chain 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on the fact that a cylindrical delimiter, which is erected by being buried in a shoulder or the like as an insertion of a road sign, is damaged by a traffic accident such as a collision with a car. The present invention relates to a device for extracting a remaining derier that remains buried.

[0002]

2. Description of the Related Art As a road sign, for example, in snowy countries, inner poles that are alternately colored red and white are used as snow poles that are extended from the derator in winter and serve as a guide for snow removal. In order to store the inner pole, the buried size of the delator is quite deep, and because it is solidified by the road shoulder structure such as concrete or asphalt, it is not easy to extract and extract it when it is damaged.

There is nothing special as a conventional tool for extracting a damaged residual delimiter, and it has a cylindrical blade for digging around the periphery with a pickaxe or for forming a large-diameter inserter hole. I was digging a hole by using a core cutter and driving it around.

[0004]

As a mode of damage due to a traffic accident, there is a case where it is bent or a case where the upper part is cut off. Since it has the shape of, there is no suitable hooking point that can be attached and it can not be pulled out as it is, so as previously mentioned, the core cutter was used in the past, but according to it, it takes time to drive. Of course, it is not easy to dig up the soil, it takes about 30 minutes, and the road manager can not do that work, so ask the contractor to remove it at a large cost. It is the current situation.

Even in the case of a bent radiator, as a temporary measure, the ground portion was cut off, a pile was inserted into the remaining underground portion, and another radiator was newly erected through the pile. If this is done, not only will the position of the inner poles and snow poles rise unevenly to support the piles, but it will also hinder the storage of the inner poles. However, the same problem occurred in this case as well.

[0006] In view of the above situation, the present invention provides a damaged residual extractor extractor capable of removing the residual residual generator as it is by a very simple operation without digging around the residual residual agent. The purpose was to.

[0007]

In order to achieve the above object, the present invention has a handle lever as a lever body pivotally supported on the upper end of a column and a hook for hooking a chain link at the tip of the handle lever. It consists of a lever, a non-return metal fitting that is hooked in the delator, and the chain that lifts the non-return metal fitting with the lever. And a length that can be inserted into the delator only by tilting it, and at both ends in the length direction, claws that can bite into the inner peripheral surface of the delimiter are formed.
A chain connecting portion was provided at the base end portion corresponding to the tilted side to construct an extractor of the damaged remaining delineator.

If the base end claw of the non-return fitting is formed so as to warp, it is more effective for achieving the purpose.

[0009]

[Operation] When the extractor for the damaged residual deriator is configured as described above, and when using this to remove the delimiter, first insert the check metal fitting into it, and then pull up the check metal fitting by levering through the chain. . In this case, if the check fitting is inserted by inclining so that the connecting part side of the chain becomes low, the pulling force will be biased to that location, and the proximal end claws will particularly come into pressure contact with or cut into the inner peripheral surface of the delator. As a result of this reaction, the tip claw is also pressed into contact with or bites into the tip claw, so that a hooking state in which the delator is pulled up can be obtained.

The hooked state becomes stronger as the resistance for pulling out the delator becomes greater, so that it will never come off and can be surely pulled out as long as the necessary force is applied to the lever.
Also, since the lever handle lever has a fulcrum at a higher position due to the column, a large amount can be pulled out. When it is not possible to pull out all at once, the length of the chain can be adjusted at the position where it is hung on the hook, and the length can be shortened and pulled out several times.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.

The drawing shows one embodiment, in which a broken remaining delithator extraction device P is composed of a lever 1, a non-return fitting 3 hooked in a delimiter D, and a chain 5 for lifting it. The lever 1 and the non-return fitting 3 are connected by a chain 5 (FIG. 1).

The lever 1 has a handle lever 9 as a lever body pivotally supported by a pin 10 on the upper end of a column 7, and a hook 11 for hooking a chain 5 at the tip of the handle lever 9 is provided by a notch. ing. A chain 5 is attached between the fulcrum pin 10 and the hook 11. Therefore, the operation of hooking the chain 5 on the hook 11 is easy.

A pipe is used for the pillar 7 of the lever 1, and a seat plate 13 is attached to the lower end of the pipe. This seat plate 13
Is intended to withstand the load and stop when the deriator D is hoisted. However, during the hoisting, the position of the hook 11 becomes a circular path along with the swing of the handle lever 9, so in relation to that. Since it is necessary to straighten and straighten the column, the column 7 is connected to the seat plate 13 so that the column 7 swings back and forth.

The non-return fitting 3 has a base end claw 17 which is bent in a bent shape in a V-shape at one end, and the base end claw 17 and the tip claw 19 at the other end are provided on the lower surface with a slope 20. , 20
Is formed, an acute angle is formed in the cross section. Further, inside the delimiter D, the contact portions 21 and 21 are formed by rounding both sides of the base end pawl 17 and the tip end pawl 19 so that they are pressed against each other in a stable manner. Further, in the check metal fitting 3, the connecting portion 23 of the chain 5 is projected in a loop shape at the bent portion of the base end portion.
Therefore, the pulling force is concentrated and applied to the base end claw 17 side.

2 and 3 show a state in which the non-return fitting 3 is hooked in the delimiter D. The hooking procedure is to raise the tip claw 19 to shorten the length when viewed from the plane. By doing so (see the chain double-dashed line in FIG. 3), the check metal fitting 3 is inserted into the delimiter D while being suspended by the chain 5, and when it reaches an appropriate position, the handle lever 9 pulls it up. Then, the base end pawl 17 side is pulled up, and the planar length of the non-return fitting 3 is increased, so that the base end pawl 17 and the front end pawl 19 are respectively in contact portions 21 ,.
At 21, the pressure is applied to the inner peripheral surface of the radiator D, and the larger the pulling force, the greater the pressure contact force.
Even if a large amount of force is required to pull up, it can be reliably pulled out as long as the force is added by lever 1.

Since the derailleur D is generally made of plastic and may be slippery for the first time when it is used as a clue, in such a case, in such a case, a tip such as a hammer may be used. Hit the 19 side down. At this time, if the chain 5 is held in a suspended state, the tip claw 19 bites into the inner peripheral surface of the delimiter D, so that the hooked state can be reliably obtained.

In order to ensure the first catch that is a clue to the inner peripheral surface of the delimiter D, a pair of left and right projections are provided at both ends in an angular shape so that the proximal end claw and the distal end claw are formed. May be formed (not shown). Although such a delimiter was prototyped prior to this embodiment, it was not necessary to make it so complicated, and it was possible to easily obtain the first hooking state which is a clue in the simple structure as shown in the drawing.

In order to obtain a catch on the delimiter D, it is necessary to be appropriately longer than its inner diameter. However, since the inner diameter of the delimiter D is not always constant, the check metal fitting 3 is replaced in that case. Therefore, the chain 5 has a joint shackle 2 that is attachable to and detachable from the connecting portion 23.
5 is attached. In addition, due to the structure of the non-return fitting 3, it can be used not only for the delimiter D but also for pulling out other cylindrical objects.

FIGS. 4 and 5 show the procedure for pulling out the delimiter D. First, the chain 5 is used for a long time, and it can be gradually shortened and pulled up to the extent that it can be pulled out by hand (FIG. 5). . And even if you follow these steps,
It could be extracted in a few minutes (30 minutes in the past).

[0021]

As described above, according to the present invention, there is provided a device for extracting a damaged residual creator which can be completely removed as it is by a very simple operation without digging up the surroundings of the residual creator. It has been successfully provided, which not only makes it possible to significantly reduce the work time for extracting the delator, but also makes the work extremely easy, so that it is not necessary to specifically request a contractor for the work. Also, since the punched hole can be used as it is for inserting a new derator,
The road administrator exhibits a number of excellent effects, such as ease of management that emphasizes safety for road managers, and equipment that is suitable for simple and inexpensive provision, which also reduces the cost of road management. .
