JP6549463B2 - Grip and safety equipment for sloped lanyards and dual safety measures for slope work - Google Patents

Description

  The present invention uses a safety measure rope (a rope different from parent ropes) to prevent workers from falling down in the construction of slopes on slopes or slopes involving work using parent ropes (ropes) Grips and safety equipment for slope lanyards for taking dual safety measures, and dual safety measures for slope work.

  When working on slopes such as slopes and collapsed areas, the slope of the structure that generally holds several main parts from the torso to the buttocks of the workers, holds the body in the working position, and prevents falling when sliding down The operator mounts the surface harness, etc., and connects the back side belt of the inclined surface harness and the main rope to the inclined surface harness via the inclined surface lanyard (also referred to as a lip lip). It supports the body in the working position on the surface.

  However, in work on a slope where work is done while keeping the position by putting weight on one parent rope, fall or fall due to the worker's roar or heat stroke etc. Remove the grip of the lanyard and change to another rope Risks such as falling due to carelessness, falling due to damage due to damage or wear due to aging of parent rope or parent rope hitting a rock angle etc., maintenance inspection or early replacement of parent rope It is difficult to eliminate it completely.

  Therefore, although safety ropes are used in addition to parent ropes, safety measures are taken to connect directly or indirectly to the D-ring of the trunk belt of the inclined surface harness or the back side belt (Non-Patent Document 1, In the upper part of the reference figure of p46), work on the inclined surface with movement in the vertical and horizontal directions, safety ropes connected directly or indirectly do not become almost parallel with parent ropes, but in an oblique state Because it is connected at an angle, it becomes an obstacle for work (very disturbing work). In addition, when it is connected indirectly, the rope left behind after the connection part becomes a hand and foot when the worker moves Since it is easy to get tangled, there has been a problem that the double safety measures that were taken to ensure safety may cause an accident such as a fall of the worker instead.

  In addition, Non-Patent Document 2 shows two types of dual safety measures, that is, a double parent system and a safety block system (Non-Patent Document 2, p3, central view). However, even if any of these methods is adopted, two ropes are connected in front of the worker's eyes not in a substantially parallel state with the parent rope but in an oblique state (in a substantially V shape) at an angle Therefore, there is a problem that the workability on the inclined surface is significantly reduced.

  In addition, according to Patent Document 1, a safety rope for preventing the operator from falling in parallel with the elevating wire is lowered from the wire anchor provided above the slope to the ground, and the slope where the operator attaches the middle of the safety rope There is disclosed a slope work safety band provided with a safety rope connection portion connected to an upper belt, a lower belt or a lifting wire connection portion of the work safety band. However, even when the slope safety belt of Patent Document 1 is used, a decrease in workability due to the two ropes being positioned in front of the worker can not be avoided (Patent Document 1, FIG. 1).

  According to the present invention, the operator can take double safety measures just by mounting the inclined surface harness in the same manner as the conventional work, and directly use the safety measure ropes that cause troubles with the work for the inclined surface. As there is no need to connect to the D ring of the harness (upper figure in reference figure 7 of Non-Patent Document 1, p. 46), the safety measure rope becomes an obstacle and an accident occurs in which the worker crawls or falls. There is no risk of doing so, and the working environment on a good slope which is the same as the conventional one using one rope can be maintained.

  Also, when spraying mortar / concrete or a vegetative base material, workers leave their weight on the rope and descend the slope while spraying the left and right construction surfaces of the parent rope while maintaining a stable posture. It is necessary to hold the spray nozzle left and right so that it straddles the rope. At this time, since the sprayed mortar and the vegetative substrate adhere to the rope, a worker usually descends while manually sweeping the extraneous matter. When the conventional double safety measures were taken, it was necessary to clean the attached matter of the two ropes connected at an angle in an oblique state, respectively, but according to the present invention, such work is complicated. Can be reduced.

  Furthermore, since the relay material and the parent rope on the extension line of the safety measure rope can be made approximately parallel, the same working environment as when using one parent rope can be maintained, It is possible to avoid work problems caused by the two ropes being stretched at an angle in front of the worker. Further, by bundling the parent rope and the safety countermeasure rope together using, for example, a cover or the like, a working environment similar to the conventional one can be obtained.

  In addition, for example, when a take-up type safety block is used as a safety measure rope, the mortar or the vegetation base adheres to the wire or belt around the hook of the safety block, which makes the winding difficult. Trouble can be avoided. Furthermore, when the safety block is used, it is not necessary for the operator to operate both the grip attached to the main rope and the slide device attached to the safety rope when moving up and down and right and left. Furthermore, when a safety block is used as a safety measure rope, the slope surface is more than the connection position between the safety block and the first connection portion provided on the grip of the slope lanyard or the second connection portion of the relay device Since there is no safety rope at the bottom, the workability is improved.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings showing the embodiments. The same or similar components in the embodiments may be given the same reference numerals and descriptions thereof may be omitted.

First, with reference to FIG.6 and FIG.7, the main instruments used by the safety measures equipment of the slope work by this invention are demonstrated.
FIG. 6 is a view showing an example of the inclined surface harness. The inclined surface harness 3 is attached to a worker, and in the operation on the inclined surface, for example, the body is held at the working position by holding the main part from the torso to the buttocks at several places or more. It is a belt of the structure to block.

  The inclined surface harness 3 mainly includes a trunk belt 10, a back side belt 11, and a drop belt 12. The hanging belt 12 connects the body belt 10 and the back side belt 11. The torso belt 10 is mounted around the waist of the worker and is fixed to the worker by the buckle 13. The back side belt 11 supports the buttocks of the worker in a wide range and holds the work position. First D rings 14 a are provided on both sides of the back side belt 11. The first hook 7a of the lanyard 4 for the inclined surface described later is engaged with the first D ring 14a provided on the back side belt 11, whereby the harness 3 for the inclined surface and the lanyard 4 for the inclined surface are connected. The torso belt 10 is optionally provided with a second D-ring 14b.

  FIG. 7 is a view showing an example of the inclined surface lanyard 4. The lanyard 4 for inclined surface is a member interposed to connect the back side belt 11 of the harness 3 for inclined surface and the parent rope (symbol 2 in FIG. 1 etc.), and the worker's body at the working position on the inclined surface. Support.

  The sloped lanyard 4 mainly includes a grip 5, two ropes (or straps) 9, and two first hooks 7a. In the present invention, the grip 5 is provided with the first connection portion 8a and the fourth connection portion 8d (the first connection portion 8a will be described later). One end of each of the two ropes 9 is attached to the fourth connecting portion 8 d of the grip 5. The other ends of the two ropes 9 each have a first hook 7a.

  In the present invention, although the first hook 7a to the fourth hook 7d are used according to each embodiment to be described later, these hooks are, for example, so-called "hooks" in a form like the first hook 7a shown in FIG. It is not limited to the hook, and may be a member connectable to the first connecting portion 8a to the fourth connecting portion 8d or the D ring provided according to each embodiment described later. Further, the first connection portion 8a to the fourth connection portion 8d are not limited to the annular connection portion as shown in FIG. The “hook” and the “connection” or the D ring in the present invention may be connectable to each other.

  The grip 5 is a member for connecting the inclined surface lanyard 4 to the main rope. The grip 5 also includes, for example, a member called a slide device that connects the lanyard and the main rope. The two first hooks 7a connect the sloped lanyard 4 to the sloped harness 3 by respectively engaging with the two first D rings 14a provided on the back side belt 11 of the sloped harness 3 .

<First embodiment of safety equipment for slope work>
A first embodiment of the safety equipment for slope work according to the present invention will be described with reference to FIG. FIG. 1 is a view showing a situation where a worker is working on a slope 1 using a parent rope 2 and a safety countermeasure rope 6.

  An inclined surface lanyard 4 is interposed between the parent rope 2 and the inclined surface harness 3 and connected to each other. The parent rope 2 and the inclined surface lanyard 4 are connected by gripping the parent rope 2 by the grips 5 of the inclined surface lanyard 4. The inclined surface harness 3 and the inclined surface lanyard 4 have two first hooks 7a of the inclined surface lanyard on the two first D rings 14a provided on both sides of the back side belt 11 of the inclined surface harness 3. They are connected by being engaged with each other.

  In addition, the grip 5 is provided with a first connection portion 8 a. The tip (lower end) of the safety measure rope 6 is connected to the first connection portion 8a, whereby the sloped lanyard 4 and the safety measure rope 6 are connected. The first connection portion 8 a can be provided, for example, by an annular member attached to the grip 5 as shown in FIG. 7 or an opening formed in the grip 5. However, the shape of the first connection portion 8a is not particularly limited. As a result, the second hook 7b provided at the tip of the safety measure rope 6 can be easily connected.

  In addition, the position of the first connection portion 8 a on the grip 5 is not particularly limited, but it is preferable to provide the first connection portion 8 a on the slope upper side of the hinge portion of the grip 5. Thereby, parent rope 2 and rope 6 for safety measures can be made approximately parallel. As a result, no trouble occurs when the worker operates the grip 5 to move up and down the slope. In addition, when a safety block is used as the safety measure rope 6, an upward force (a force of winding up the safety block) acts on the first connection portion 8a, which is also preferable from a mechanical point of view.

  For example, a synthetic fiber rope or the like having a diameter of 18 mm can be used as the proline 2 and is fixed to a fulcrum provided at the top of the inclined surface.

  As the safety rope 6, it is preferable to use a safety block. The safety block locks when a sharp downward force is applied, and may be a wire rope winding type or a belt winding type. The maximum risk of worker fall is disconnection of parent 2 but when the rapid downward force at that time is applied to the safety block, it is securely locked, and it is possible to prevent the worker from falling. In addition, since the safety block is of the automatic winding type, when the working position is changed, it is sufficient for the worker to operate only the grip 5 so that the workability is good.

  Safety blocks are commercially available as crash protection devices. One example of the configuration of the safety block is a wire rope or a belt provided with a second hook 7b at the tip end for connecting with another member as shown in FIG. 1 (hereinafter, wire rope and belt are generically called wire rope etc. And a case (not shown) for winding and storing a wire rope etc., and a safety block attached to the case for fixing directly or indirectly using a hanging rope as a fulcrum The carabiner, the shackle and the like (not shown) are provided.

  When a safety block is used as the safety measure rope 6, the second hook 7b provided at the tip of the wire rope, belt or the like is connected to the first connection portion 8a of the grip 5 of the sloped lanyard 4 There is no wire belt or the like of the safety block only at the parent rope 2 below the inclined surface than at the connection position. As a result, the risk of workers being crawled can be eliminated, and the workability is improved.

  Moreover, as the rope 6 for safety measures, the same rope as parent rope 2 can also be used. In this case, the safety measure rope 6 is fixed at a position different from the fulcrum of the parent rope 2 at the position in the top direction of the slope. In this case, when changing the working position, the operator is required to operate both the grip 5 and the sliding device for the rope, so the workability is inferior to the safety block.

<Second embodiment of safety equipment for slope work>
The second embodiment of the safety equipment for slope work according to the present invention will be described with reference to FIGS. FIG. 2 is a view showing a situation where a worker is working on the slope 1 using the parent rope 2 and the safety measure rope 6.

  An inclined surface lanyard 4 is interposed between the parent rope 2 and the inclined surface harness 3 and connected to each other. The parent rope 2 and the inclined surface lanyard 4 are connected by gripping the parent rope 2 by the grips 5 of the inclined surface lanyard 4. In the inclined surface harness 3 and the inclined surface lanyard 4, the two first hooks a of the inclined surface lanyard 4 are provided on both sides of the back side belt 11 of the inclined surface harness 3 Are connected by being engaged with each other.

In the second embodiment, the relay material 21 and the relay device 22 are further provided.
As shown in the partial enlarged view of FIG.2 and FIG.3, the relay material 21 intervenes between the rope 6 for safety measures, and the lanyard 4 for slopes, and is connected with each. In the illustrated example, the lower end of the relay member 21 is connected to the first connection portion 8 a of the grip 5 of the inclined surface lanyard 4. On the other hand, the upper end of the relay member 21 is connected to the safety countermeasure rope 6 via the relay device 22 mounted on the parent rope 2.

  The relay device 22 is attached to the main rope 2 so as to be able to move up and down along the main rope 2. As a method of mounting the relay device 22 so as to be able to move up and down along the parent rope 2, for example, the relay device 22 has a structure having a hollow portion through which the parent rope 2 is inserted. In order to reduce the resistance when the relay device 22 moves (lifts) the parent rope 2 up and down, as shown in FIGS. 2 and 3, the relay device 22 includes a pair of pulleys 31 sandwiching the parent rope 2. Although it is preferable to include, the mechanism for enabling the relay device 22 to be moved up and down along the main rope 2 is not limited.

  FIG. 4 is a partially enlarged view of an example of the relay device 22 not having a pulley. The relay device 22 includes a second connection portion 8 b and a third connection portion 8 c. The second hook 7b at the lower end of the safety measure rope 6 is connected to the second connection portion 8b of the relay device 22, and the third hook 7c at the upper end of the relay member 21 is connected to the third connection portion 8c.

  When the relay device 22 is attached to the main rope 2, the second connection portion 8b of the relay device 22 is located on the top side of the inclined surface, and the third connection portion 8c is located on the opposite side to the top of the inclined surface Preferably, they are provided. As shown in FIG. 3 and FIG. 4, the second connecting portion 8 b functions as a third connecting portion 8 c depending on the mounting direction of the relay device 22 to the parent rope 2 by making the relay device 22 symmetrical. It is preferable that the third connection portion 8c can function as the second connection portion 8b (that is, the relay device 22 may be attached in either left or right direction). However, as in another example of the relay device 22 shown in FIG. 5, one connecting portion that doubles as the second connecting portion 8 b and the third connecting portion 8 c is provided substantially vertically to the main rope 2. Alternatively, they may be provided substantially vertically in the lateral direction with respect to the main rope 2.

  The relay member 21 preferably includes, for example, a lanyard (strap) or a rod-like member, and a third hook 7c attached to each end thereof. The advantages of using the relay material 21 are as follows. Because the fulcrum of the parent rope 2 installed at the top of the inclined surface and the fulcrum of the safety measure rope 6 are separated to the left and right, the parent rope 2 and the safety measure rope 6 are predetermined in front of the worker (The symbol θ in FIGS. 1 and 2). By using the relay material 21, the vertex position of the angle at which the angle θ opens can be kept away from the worker by the length of the relay material 21, and the parent rope 2 and the relay material 21 are vertically moved in front of the worker Can be kept substantially parallel. That is, if the relay member 21 is regarded as an extended portion of the safety measure rope 6, from the viewpoint of the worker, the parent rope 2 and the safety measure rope 6 can be made to approximately vertically overlap with each other. It becomes possible to work as if there is only a rope, and work problems can be eliminated.

  Further, by bundling the substantially parallel parent ropes 2 and the relay members 21 with a cover or the like, the same work environment as that in which only one parent rope is connected can be created. The length of the relay material 21 takes into consideration the working angle at which the worker attaches the relay device 22 to the master 2 and the connection angle allowed for safety, and the range in which the mortar and the vegetative substrate scatter from the nozzle tip during the spraying operation. It is about 0.5 to 2.5 m, more preferably about 1.0 to 2.0 m.

<Modification of Second Embodiment>
Although not shown, as a modification of the second embodiment, the relay member 21 may be connected to the inclined surface harness 3 instead of being connected to the inclined surface lanyard 4. That is, the relay member 21 may be directly connected to the inclined surface harness 3 without passing through the inclined surface lanyard 4. When connecting to the inclined surface harness 3, the lower end of the relay member 21 is connected to, for example, the second D ring 14 b of the trunk belt 10. In this case, although the workability is slightly reduced compared to the first and second embodiments, substantially the same effect can be expected as a safety measure.

  Also in the second embodiment and its modified embodiment, if a safety block is used as the safety measure rope 6, the wire rope of the safety block only with the relay material 21 and the parent rope 2 below the inclined surface than the relay device 22. Workability is improved because there is no etc.

<Third Embodiment of Safety Equipment for Inclined Surface Work>
A third embodiment of the safety equipment for slope work according to the present invention will be described with reference to FIGS. 8 and 9. FIG. 8 is a view showing a situation where a worker is working on the slope 1 using the parent rope 2 and the safety measure rope 6. FIG. 9 is a view showing an example of a relay material 21A of the present embodiment.

  An inclined surface lanyard 4 is interposed between the parent rope 2 and the inclined surface harness 3 and connected to each other. The parent rope 2 and the inclined surface lanyard 4 are connected by gripping the parent rope 2 by the grips 5 of the inclined surface lanyard 4. In the inclined surface harness 3 and the inclined surface lanyard 4, the two first hooks 7a of the inclined surface lanyard are provided on the two side portions of the back side belt 11 of the inclined surface harness 3 Are connected by being engaged with each other.

  In the present embodiment, a relay material 21A having a form different from that of the relay material 21 used in the second embodiment described above is provided. As shown in FIG. 9, the relay member 21A comprises a lanyard (strap), a third hook 7c attached to each end of the lanyard (strap), and a fourth hook 7d slidable along the relay member 21A. It is suitable. In the example of FIG. 9, although the relay material 21A is inserted through the annular connection portion provided to the fourth hook 7d, any shape may be used as long as the fourth hook 7d can slide along the relay material 21A. .

  As shown in FIG. 8, the third hook 7 c at the upper end of the relay material 21 </ b> A is connected to the relay device 22. The form of the relay device 22 and the connection between the relay device 22 and the relay material 21A are the same as those in the second embodiment described above. Further, the relationship between the relay device 22 and the parent group 2 is also the same as that in the second embodiment described above.

  The third hook 7c at the lower end of the relay member 21A is connected by being engaged with the inclined surface harness 3 (for example, the second D ring 14b provided on the trunk belt 10).

  The fourth hook 7d slidable along the relay member 21A is connected to the sloped lanyard 4 by being engaged with the fourth connection portion 8d of the grip 5 of the sloped lanyard 4. In this example, the fourth connection portion 8d for the rope 9 in the grip 5 is also used, but may be connected to another connection portion (for example, the first connection portion 8a) other than the fourth connection portion 8d. In addition, when the interface between the attachment portion to the relay member 21A in the fourth hook 7d and the hook portion is made rotatable, the hook portion of the fourth hook 7d is connected to the grip 5 of the inclined surface lanyard 4 It is preferable because the workability is improved.

  The advantages of using the relay 21A are as described in the second embodiment described above. By using the relay material 21A, the vertex position of the angle at which the angle θ opens can be kept away from the worker by the length of the relay material 21A, and the parent rope 2 and the relay material 21A are vertically moved in front of the worker It can be kept substantially parallel to the direction. That is, when the relay member 21A is regarded as an extension of the safety measure rope 6, the parent rope 2 and the safety measure rope 6 can be substantially vertically overlapped with each other as viewed from the worker, so it is as if only one It becomes possible to work as if there is only a rope, and work problems can be eliminated.

<Modification of Third Embodiment>
A modification of the third embodiment will be described with reference to FIG. FIG. 10 is a view showing a situation where a worker is working using the parent rope 2 and the safety measure rope 6 on the slope 1.

  In the modification shown in FIG. 10, instead of connecting the fourth hook 7d of the relay member 21A shown in FIG. 9 to the grip 5 of the sloping surface lanyard 4, the fourth hook 7d is used as the back side of the sloping surface harness 3. The belt 11 is engaged with and connected to one of the two first D rings 14 a of the belt 11. That is, 21 A of relay materials are not connected with lanyard 4 for slopes, but are connected only with harness 3 for slopes.

  Even in this modification, although it is possible to keep the parent rope 2 and the relay member 21A in a substantially parallel state, the substantially parallel state may be slightly broken depending on the posture of the worker. However, since the effect of improving the workability of the inclined surface work is sufficiently obtained as compared with the conventional double safety measures, the connection for connecting the fourth hook 7d to the grip 5 shown in the third embodiment It can be adopted when the department can not be secured.

  Also in the third embodiment and its modified embodiment, if a safety block is used as the safety measure rope 6, the relay material 21A and the parent rope 2 can be located below the connecting position of the safety block and the relay device 22 on the slope. Workability is improved because there is no wire rope of safety block only.

<Double safety measures in slope work>
A dual safety measure method in slope work according to the present invention will be described. In the description, reference numerals in the above-mentioned drawings are referred to.

-When using the safety countermeasure equipment of 1st Embodiment In one form of the double safety countermeasure method in inclined surface operation | work by this invention, the safety countermeasure equipment of 1st Embodiment mentioned above is used. As one example, parent rope 2, safety block 6 as safety measures rope, inclined surface harness 3 and inclined rope lanyard 4 interposed between parent rope 2 and inclined surface harness 3 to connect them And use. The inclined surface harness 3 is mounted on a worker and connected to the main rope 2 via the inclined surface lanyard 4 in the same manner as the conventional safety measures for the inclined surface work.

  And in this form, it has the step which connects the 2nd hook 7b provided in the lower end of the wire rope etc. of the safety block 6 to the 1st connection part 8a provided in the grip 5 of the lanyard 4 for slopes.
