Description

  The present invention relates to a slinging work experience apparatus used when a student performs a simulated training for slinging work in a slinging work class or the like.

  The slinging work of hanging a load on a hook such as a crane or a chain block with a wire rope or a chain is a dangerous work if it is hung incorrectly. For this reason, with the aim of preventing accidents by enhancing workers' ability to predict danger, staking classes and staking skills classes are held as advance safety education for those who are going to engage in staking work. ing.

  In slinging workshops, etc., lectures are given by specialized instructors according to prescribed programs, etc., and participants use cranes, wire ropes and luggage (hanging loads) that are actually used for slinging. In many cases, they are trying to experience a slinging work.

  On the other hand, as a prior art related to the present invention, for example, there is a “suspended load handling simulation training apparatus” described in Patent Document 1. This "suspended load handling simulation training device" was developed for the purpose of performing sling simulation training without using actual equipment such as cranes and hoists that are used in production lines. Cranes and chain blocks.

Japanese Patent Laid-Open No. 2003-5621

  It is an advantage that the slinging work using an actual crane or the like performed in a conventional slinging class can experience the slinging work in the same state as the actual slinging work. However, when the “single-hanger work” as shown in FIG. 8, which is a forbidden work on the slinging work, is executed, a dangerous situation may occur. That is, as shown in FIG. 8, one wire rope 81 is wound around a suspended load 80 such as a steel pipe, and the wire rope 81 is hung on a hook 82 such as a crane (not shown) ("1 When the student performs “main suspension work”), a dangerous situation may occur in which the suspended load 80 tilts or rotates in the same manner as when the “one-line suspension work” is performed at the actual site. is there.

  Therefore, in a slinging workshop, using a real crane or the like to let the students experience the “one-lifting work”, which is a prohibited work, is unavoidable in terms of ensuring safety. . For this reason, it is pointed out that a sufficient educational effect has not been obtained from the viewpoint of preventing the accident by increasing the worker's ability to predict the danger of prohibited work.

  On the other hand, as shown in FIG. 8, when the “one-hand suspension work” is performed using the “suspended load handling simulation training device” described in Patent Document 1, as shown in FIG. Therefore, it is possible to prevent the student from experiencing the “single lifting work” as a mock practice.

  Therefore, the problem to be solved by the present invention is to provide a slinging work experience device that can safely experience a single hangering work, which is a forbidden work in slinging work, and can reliably acquire the ability to predict the danger. There is.

  The slinging work experience apparatus of the present invention causes the suspended load member to move up and down via a suspended load member attached to a support means via a hinge mechanism so as to be able to be raised and lowered, and a string-like body locked to the suspended load member. And an elevating mechanism. Here, the support means is to support the suspended load member in a undulating manner via a hinge mechanism such as ground, floor, support member, support plate, support structure, vehicle body, ship hull, fuselage, or building frame. The string-like body means a flexible member that can be locked to a suspended load member such as a wire rope or a chain and can lift the suspended load member.

  With such a configuration, when a student of a slinging class or the like locks the string-like body to the suspended load member and lifts the suspended load member using the lifting mechanism, the suspended load member is a hinge. Since it rises around the mechanism and is in an inclined state, it can be in a so-called “one-hanger operation” state. At this time, since the suspended load member is mounted on the support member via the hinge mechanism, the suspended load member is stably held in a fixed inclination posture, and does not swing or rotate.

  For this reason, the student can safely experience the single-hanger work, which is a forbidden work in the sling work. Further, as described above, when the suspended load member is lifted by the lifting mechanism, the string-like body, the suspended load member, and the like are in the same situation as when the “single suspension work” is performed, and the “single suspension work” is reproduced. Therefore, the student can surely acquire the ability to predict the danger of the “one-hanger operation”.

  Here, it is desirable to provide an obstacle member at a position where a part of the suspended load member approaches and separates with the raising and lowering operation of the suspended load member centering on the hinge mechanism.

  With such a configuration, there is a risk of causing an accident in which a part of the body, an article, or the like is caught between the suspended load member and the obstacle member that is lifted when the “one-hanger operation” is performed. This is effective for the learner to acquire the ability to predict the danger of the “single-hanging work”.

  In this case, it is desirable to provide a member to be pressed that is sandwiched between a part of the suspended load member and the obstacle member.

  With such a configuration, the situation when a part of the body or an article is sandwiched between the suspended load member and the obstacle member that is lifted can be more realistically reproduced. The danger of “work” can be acquired more reliably.

  On the other hand, it is possible to provide a buffer mechanism that relaxes the falling speed of the suspended load member. With such a configuration, when the suspended load member lifted by the lifting mechanism is returned to the original posture, it can be laid down at a slow speed, so that safety is improved.

  Furthermore, it is possible to provide an alarm mechanism that emits an alarm sound in accordance with the overturning operation of the suspended load member. With such a configuration, it is possible to alert the person in the surroundings that the overturning operation of the suspended load member lifted by the lifting mechanism has started, and to call attention, so that safety can be ensured. It is effective from the viewpoint.

  According to the present invention, it is possible to provide a slinging work experience device that can safely experience a single hangering work that is a forbidden work in a slinging work and can surely acquire the ability to predict the danger.

As shown in FIGS. 1 to 5, the slinging work experience apparatus 100 according to the present embodiment includes a suspended load member 12 that is mounted on a support member 10 that is one of support means via a hinge mechanism 11 so as to be raised and lowered. And an elevating mechanism 14 that moves the suspended load member 12 up and down via a string-like body 13 locked to the suspended load member 12. In addition, since a support means is not limited to the support member 10, as long as it can support the hanging load member 12 via the hinge mechanism 11 so that raising / lowering is possible, for example, a ground, a floor surface, a support member, a support board, A support structure, a vehicle body, a hull, an airframe, or a building frame can also be used.

  The support member 10 is a member having a ladder shape in plan view formed by joining H-shaped steels vertically and horizontally, and the suspended load member 12 has circular openings 12y at both ends of a cylindrical body 12x having a predetermined length. It is a hollow member formed by closing with plate-like partition walls 12a and 12b. On the outer peripheral surface of the suspended load member 12, broken-line marks L <b> 1 and L <b> 2 are drawn along the circumferential direction to indicate an appropriate region for winding and locking the string-like body 13. Marks L1 and L2 are displayed in the vicinity of the center of the suspended load member 12 in the axis 12c direction at a predetermined interval, and the center of gravity (not shown) of the suspended load member 12 is located between the marked lines L1 and L2. Yes.

  In addition, a pair of obstacle members 15 are provided at positions where the partition wall 12b forming a part of the suspended load member 12 approaches and separates as the suspended load member 12 moves up and down around the hinge mechanism 11. The two obstruction members 15 are parallel to each other with the axis 12c of the suspended load member 12 sandwiched between the end portion 10b of the support member 10 on the hinge mechanism 11 side, and are fixed in an upright state.

  When the partition wall 12 b of the suspended load member 11 approaches the obstacle member 15, the semi-cylindrical pressed member 16 sandwiched between them (between the partition wall 12 b and the obstacle member 15) uses a plurality of screws 19 for the obstacle member 15. And is detachably attached. The pressed member 16 is formed of a softer material than the partition wall 12 b and the obstacle member 15. In addition, since it does not limit to the obstruction member 15, as long as the to-be-pressed member 16 can be hold | maintained, things other than the obstruction member 15, for example, the housing of a building, a wall surface, or a structure can also be used.

  As shown in FIG. 3 and FIG. 5 to FIG. 7, the air cylinder 17, which is a buffering mechanism that relaxes the falling speed of the suspended load member 12, is attached to the end 10 a of the support member 10 on the side opposite to the hinge mechanism 11. 10 and the air cylinder 17 are arranged so as to be connected to each other so as to be close to and away from each other. The lower end portion 17b of the air cylinder 17 is pivotally supported by a mounting member 18b fixed on the end portion 10a of the support member 10, and the upper end portion 17a side of the air cylinder 17 is at the lowermost portion of the suspended load member 12. The upper end 17a is pivotally supported by an attachment member 18a which is inserted into the suspended load member 12 through the established hole 12z and fixed to the uppermost portion of the inner peripheral surface of the suspended load member 12. .

  As shown in FIGS. 6 and 7, the air cylinder 17 can be expanded and contracted in the longitudinal direction in accordance with the raising and lowering operation of the suspended load member 12 centering on the hinge mechanism 11, and when the extended air cylinder 17 contracts. Demonstrate the attenuation function. Further, a horn 20 that is a warning mechanism that emits a sound in accordance with the overturning operation of the suspended load member 12 is attached to the lower end portion 17 b side of the air cylinder 17. The horn 20 has a function of generating an alarm sound by blowing with air discharged from the air cylinder 17 when the air cylinder 17 contracts in accordance with the overturning operation of the suspended load member 12.

  As shown in FIGS. 1 and 6, in a slinging work experience apparatus 100, a student of a slinging class or the like wraps and locks a string-like body 13 around a suspended load member 12, and its upper end is lifted and lowered. 14, the lifting mechanism 14 is actuated, and as shown in FIG. 7, when the suspended load member 12 is lifted up, the suspended load member 12 rises around the hinge mechanism 11 and is inclined, It is possible to reproduce the so-called “single hanger” state. At this time, since the suspended load member 12 is mounted on the support member 10 via the hinge mechanism 11, the suspended load member 12 is stably held in a fixed inclination posture and does not swing or rotate. .

  For this reason, the student can safely experience the “one-hanger work” which is a prohibited work in the slinging work. Further, when the suspended load member 12 is lifted by the elevating mechanism 14, the string-like body 13, the suspended load member 12 and the like are in the same situation as when performing the "single lifting work", and the "one lifting work" is reproduced. Therefore, the student can surely acquire the ability to predict the danger of the “one-hanger operation”.

  In addition, since the obstacle member 15 is provided at a position where one partition wall 12b of the suspended load member 12 approaches and separates when the suspended load member 12 is raised and lowered with the hinge mechanism 11 as the center, the “one lifting operation” is performed. , It is possible to visually recognize that there is a risk of an accident in which a part of the body or an article is caught between the partition wall 12b of the suspended load member 12 and the obstacle member 15 Therefore, it is effective for the learner to acquire the ability to predict the danger of “one-hung work”.

  Further, in the slinging work experience apparatus 100, the suspended member 12 and the obstacle member 15 to be lifted are provided because the pressure member 16 sandwiched between the partition members 12b of the hanging member 12 approaches the obstacle member 15 is provided. The situation when a part of the body or an article is sandwiched between the two can be reproduced more realistically, and the danger of “one-hung work” can be learned more reliably.

  On the other hand, by providing the air cylinder 17 that relaxes the falling speed of the suspended load member 12, when the suspended load member 12 lifted by the lifting mechanism 14 is returned to the original posture, it can be lowered at a slow speed. It is effective for ensuring safety.
