  In the safety experience facility as disclosed in Patent Document 1, a simulation practice concerning handling of a suspended load is mainly performed. Specifically, it is possible to recognize the impact force due to a fall accident when an operator is working with a safety belt, or to recognize the load on a sling rope due to the slant of the suspended load during sling work on the suspended load. For practical training.

The frame for a safety sensation facility (hereinafter simply referred to as the frame 10) capable of performing such various simulation exercises is at least a basic slab 12, a floor slab (first floor slab 40, second floor slab 48), and And a plurality of support columns 28 for supporting the floor slab. The foundation slab 12 is a floor serving as a base point for erecting a column 28 whose details will be described later. The basic slab 12 has a substantially rectangular planar form, and the planar form is rectangular in the forms shown in FIGS. 1 and 2. By making the planar form of the foundation slab 12 rectangular, it becomes easy to mount the transportation vehicle 100 (see FIG. 8), which will be described in detail later, on the loading platform. This is because the mounting area can be effectively utilized without protruding from the loading platform 104.

  On the short side of the foundation slab 12, an outrigger 16 is provided that can extend in a direction crossing the long side. This is because by extending the arm 18 of the outrigger 16, it is possible to widen the support position when supporting the foundation slab 12, and to prevent the frame 10 from falling. The outrigger 16 according to the embodiment includes an arm 18, a cylindrical body 20 provided at the tip of the arm 18, and a leg portion 22 that can slide in the height direction via the cylindrical body 20. Since the leg portion 22 is configured to be slidable with respect to the cylindrical body 20, the leg portion 22 is protruded and stored on the upper side of the cylindrical body 20 in the transportation mode, and the leg portion 22 of the cylindrical body 20 is stored in the installation mode. The base slab 12 can be supported by protruding downward. In addition, the leg part 22 should just be set as the structure fixed with the insertion / extraction pin etc. which are not shown in figure with respect to the cylinder 20. FIG.

  Further, in the installed state, it is preferable to arrange the hydraulic jack 24 below the leg portion 22 so as to adjust the height and horizontal adjustment of the foundation slab 12. In addition, it replaces with arrange | positioning the hydraulic jack 24 under the leg part 22, and it is good also as a structure which gives the jack-up function to leg part 22 itself.

  In the center of the foundation slab 12, a through hole (opening) 14 for passing a suspended load is provided. This is because even when a heavy object is unloaded by the crane 52 described in detail later, the installation state of the frame 10 can be stabilized by using the through hole 14 provided in the center. A safety fence 26 is installed around the through hole 14 to prevent a worker or the like from falling.

  The foundation slab 12 is provided with a plurality of (four in the example shown in FIGS. 1 and 2) support columns 28 erected upward at least at the four corners. As shown in FIG. 3, each column 28 has a so-called telescopic structure in which the inside is hollow, and a cylinder having a small cross-sectional area is accommodated in a cylinder having a large cross-sectional area, thereby enabling expansion and contraction of the whole. ing. The support 28 shown in FIG. 3 has a three-node structure, and has a base support 30 having the largest cross-sectional area, an intermediate support 32 that can be stored in the base support 30, and a tip that can be stored in the intermediate support 32. It consists of a support 34.

  A beam fixing portion 36 that engages the beam 38 is provided on the distal end side of the intermediate column 32 and functions as a stopper at the time of contraction. Moreover, since the 2nd floor slab 48 mentioned later for details is provided in the upper end of the front-end | tip support | pillar 34, neither the intermediate | middle support | pillar 32 nor the front-end | tip support | pillar 34 will be stored completely. The intermediate column 32 and the tip column 34 are configured to maintain the extended state by inserting the insertion / removal pins 31 and 33 through the through holes 35. The insertion and removal pins 31 and 33 are provided with a split pin for retaining them, so that there is no need for tightening or loosening compared to bolts and nuts. The safety of the state can be increased.

  The frame 10 according to the embodiment is provided with two floor slabs (a first floor slab 40 and a second floor slab 48). The 1st floor slab 40 is a floor arrange | positioned just above the foundation slab 12 which mentioned the detail above. The first floor slab 40 can be fixed at a desired height by engaging with the floor support member 44 locked to the intermediate column 32. As shown in FIG. 4, the floor support member 44 includes a sandwiching piece 44b cut into a forked shape, a main body 44a, and a flange 44d. The sandwiching piece 44b is a pair of sections formed by cutting out one end of the main body, and is arranged so that the intermediate strut 32 is fitted into the cutout between the sections. The clamping piece 44b is provided with a through-hole 44c for inserting an insertion / removal pin (not shown) for fixing. The main body 44a may be a hollow square member, and the flange 44d is provided at the other end of the main body 44a. This is because the first floor slab 40 is engaged. Similar to the foundation slab 12, the first floor slab 40 is provided with a through-hole (opening) 42 for allowing the suspended load to pass therethrough. This is because even when a heavy object is unloaded by the crane 52, the installation state of the frame 10 can be stabilized by using the through hole 42 provided in the center. Around the through-hole 42, a safety fence 46 is installed to prevent a worker or the like from falling. Note that the installation height of the first floor slab 40 can be changed depending on the mounting position of the floor support member 44 with respect to the intermediate column 32.

  The second floor slab 48 is a floor provided at the tip of the tip support column 34 and disposed on the upper part of the first floor slab 40. A stanchion 64 is provided at the outer edge of the second floor slab 48 to prevent it from falling. In addition, a rail 50 and a crane 52 traversing the rail 50 are provided below the second floor slab 48.

  The rail 50 is disposed below the beam 700 disposed below the second floor slab 48 so as to be orthogonal to the beam 700 and along the longitudinal direction of the second floor slab 48. It passes through the upper portions of the through holes 42 and 14 provided in the foundation slab 12. Moreover, the rail 50 is comprised so that a longitudinal direction length may become longer than the 2nd floor slab 48, the 1st floor slab 40, and the foundation slab 12, and when the frame 10 is planarly viewed, it is at least one end. The portion is provided so as to protrude from the second floor slab 48, the first floor slab 40, and the foundation slab 12. By setting it as such a structure, it becomes possible to unload the hanging load in the outer side of the frame 10, and to perform a drop test (practice) and a suspension test (practice) in a protrusion part. In addition to the rail 50, a hook 701 is provided below the beam 700, and a chain block 70 (see FIG. 6) or the like can be installed.

The crane 52 includes a trolley 54 and a crane main body 62. The trolley 54 is a moving means including a roller that can traverse the rail 50 described above. The crane main body 62 is a lifting means including a motor 56, a hook 60, a wire 58, and the like.
Further, the frame 10 having the basic configuration as described above can be provided with an elevator ladder (not shown), auxiliary leg portions for stabilizing the installation state, braces or the like as necessary.

  In the frame 10 having such a basic configuration, various exercises can be performed by switching the experimental means to be installed. For example, as shown in FIG. 5, the crane 52 is moved to the protruding portion of the rail 50, and the hook 60 is engaged and pulled up to the safety belt of the worker wearing the safety belt waiting on the ground. It is possible to perform a hands-on experience of hanging safety belts for verifying biting into the body accompanying the wearing position of the child. In addition, if a safety belt hook (not shown) is hung on the safety fence 46 near the opening 42 in the first floor slab 40 and a weight (not shown) is dropped from the opening 42, the safety associated with the hooking method is achieved. It is possible to conduct safety belt fall verification training that demonstrates the danger of stripping.

  In addition, as shown in FIG. 6, a plurality of (two in the example of FIG. 6) chain blocks 70 are installed on hooks 701 provided under the beam 700 on the rail 50 instead of the crane 52. Thus, it is possible to suspend the heavy object 80. As a result, it is possible to perform a practical experience of inspecting the danger sensation of the phase hanging bracket 82 and verifying a change in load on the wire 84 or the like accompanying a change in the phase suspension angle. In addition, it is possible to practice such that the wire 84 is broken by the unloading of the heavy object 80 by the damaged wire 84 and the heavy object 80 is dropped.

  Furthermore, as shown in FIG. 7, by moving up and down to the second floor slab 48, it is possible to perform an elevating body feeling training to a high place. In addition, by applying a load to the stanchions 64 provided on the second floor slab 48, it is possible to perform a practice of verifying the load resistance of the stanchions 64.

  The number of training items that can be experienced can be increased by adding various experimental means. About the experimental means to add, you may always have as an element which comprises the frame 10, and you may make it transport separately as needed.

  The frame 10 having such a basic configuration can be mounted on the transport vehicle 100 as shown in FIGS. 8 and 9 by shortening the support column 28 and pulling up the leg portion 22. In addition, although it can be mounted on a transport vehicle even in a state in which the support column 28 is extended, in order to stabilize the transport state and pass through the overhead, It is desirable to make the height as low as possible. FIG. 8 is a diagram showing a front configuration of the transportation mode of the frame, and FIG. 9 is a diagram showing a configuration of the right side surface.

  In the transport mode, as shown in FIGS. 8 and 9, the floor support member 44 is removed, and the first floor slab 40 is disposed on the foundation slab 12. The pins of the leg portions 22 at the four corners of the foundation slab 12 are removed, and the leg portions 22 are moved upward. In FIG. 9, the leg portion 22 acts as a fence for preventing members of the other frame 10 from falling from the loading platform 104 of the vehicle 100. For this reason, the safety fence 26 provided on the foundation slab 12 is removed and disposed on the first floor slab 40. Similarly, the stanchions 64 on the second floor slab 48 are also removed and placed on the first floor slab 40. As described above, the frame 10 according to the present embodiment can reduce the overall height to about ¼ in the transportation form compared to the installation form (two steps by the support column 28 and one step by the leg portion 22). Shortened). Therefore, it can be stably mounted on the transport vehicle 100 and is not easily affected by road conditions and the like, and can be easily and safely transported to the vicinity of the work site.

  In addition, according to the frame 10 according to the embodiment, as described above, by changing the experimental means to be added, without reducing the experience content by the safety experience equipment installed in the training center or the like, in the vicinity of the work site in a remote place Training can be conducted.

  The transition from the transport mode to the installation mode of the frame 10 having the above configuration will be described with reference to FIG. First, the frame 10 mounted on the transport vehicle 100 is carried to the installation location where the training is scheduled to be performed (S100).

  After the transportation to the destination is completed, the leg portion 22 is erected. First, the leg 22 is erected by extending the arm 18 (see FIG. 9 and the like) of the outrigger 16. Next, the leg portion 22 that has been lifted to the upper side of the foundation slab 12 with the cylindrical body 20 as a base point is lowered to the lower side of the foundation slab 12. At this time, a hydraulic jack 24 is disposed below each leg 22. After the leg portion 22 is lowered and fixed, the hydraulic jack 24 is operated (extended) to push up the foundation slab 12 from the loading platform 104 of the transport vehicle 100. At this time, the height and the horizontal state of the foundation slab 12 are adjusted by adjusting the push-up amount of the hydraulic jack 24 arranged at the lower part of each leg 22 (S102).

  After pushing up the foundation slab 12 from the loading platform 104 of the transportation vehicle 100, the transportation vehicle 100 is moved forward and the loading platform 104 is pulled out from under the foundation slab 12. After the loading platform 104 is pulled out from the foundation slab 12, the column 28 is stretched through a crane or the like. For this reason, it is desirable to employ a vehicle equipped with the cab back crane 102 as the transport vehicle 100. This is because the cab back crane 102 mounted on the transport vehicle 100 can be used for the work of extending the column 28.

  The column 28 is stretched by pulling up the whole from above the second floor slab 48 with a crane (for example, the cab back crane 102). Then, after extending the intermediate column 32 and the tip column 34, respectively, the column 28 is fixed by the insertion / removal pin to complete the expansion of the column 28 (S104).

  After finishing the extension of the column 28, the floor support member 44 is locked to the intermediate column 32 (S106). Thereafter, the first floor slab 40 is pulled up using the crane 52, and the floor support member 44 and the first floor slab 40 are engaged (S108). After finishing the engagement of the first floor slab 40, the safety fence 26 and the stanchions 64 are installed on the foundation slab 12 and the second floor slab 48, respectively. Then, installation of the frame 10 is completed by attaching a ladder for raising and lowering (not shown) as necessary (S110).
