(Function)
With reference to FIG. 1 thru | or FIG. 6, the effect | action of the fire pump unloading apparatus A1 and the fire engine 9 provided with the same is demonstrated. In particular, reference is mainly made to FIG. 6 for the procedure.

The fire pump unloading apparatus A1 is fixed to the loading platform 90 of the fire engine main body. The loading platform 90 is equipped with various fire fighting equipment such as a hose and a nozzle (not shown).
The fire pump unloading device A1 can also be attached to an automobile such as a truck which is a general car. The fire pump loading / unloading device A1 is fixed in such a way that the lifting / lowering body 3 is located on the rear side and can be lifted / lowered without any trouble when the movable base 2 is pulled backward to raise / lower the lifting / lowering body 3. 1 is fixed by a fixing tool 19 (see FIG. 4). Thereby, the fire engine 9 provided with the fire pump unloading device A1 is configured.

  When the fire pump 5 is housed, the movable table 2 is positioned closer to the front of the fixed guide 1 (the position indicated by the imaginary line in FIG. 1A), and the lifting body 3 moves the movable table 2. It is raised to a position where it does not get in the way (the lifting frame 30 of the lifting body 3 is the same height as the base frame 20 of the movable table 2). In addition, the fire truck 5 is loaded and fixed on the transport carriage 4 held by the carriage holding arm 31 of the elevating body 3.

  Then, the movable table 2 is moved forward along the fixed guide 1, and the engagement pins 313 provided at the distal end portion of one arm 311 of the cart holding arm 31 are angle plates 151, 152 of the fixing support 15. Further, the fixing pin 13 is inserted into the insertion hole 153, and the movement of the engaging pin 313 in the front-rear direction is stopped. It can be fixed (see the phantom line in FIG. 4A, FIG. 4B, and FIG. 6A). The fire truck 9 is thus run in a state where the elevator 3, the transport carriage 4, and the fire pump 5 are in the accommodation position together with the movable base 2.

  In the event of a fire, the fire pump 5 is lowered from the loading platform 90 after arriving at the fire site with the fire engine 9. Specifically, the fixing pin 13 that has fixed the moving base 2 is first extracted, and the moving base 2 is moved to the rear end of the fixed guide 1 together with the lifting body 3, the transport carriage 4 and the fire pump 5. At this time, the traveling roller 220 on the rear side of the moving table 2 hits the stopper screw 100 at the rear end of the guide body 10, and the moving table 2 stops.

  When the fixing pin 13 is inserted into the insertion hole 14 of the guide body 10 at the stop position of the moving base 2, the front and rear of the traveling roller 220 are sandwiched between the fixing pin 13 and the stopper screw 100, and the traveling roller 220 is It can hardly move in the front-rear direction, and the movable table 2 is substantially fixed at the pulled-out position (see the solid lines in FIGS. 4A and 4B, see FIG. 6B). The stop position of the movable table 2 is set to a position where the lifting body 3 and the transport cart 4 do not hit the loading platform 90 and the step at the rear of the loading platform 90 when raising and lowering the lifting assembly 3 as described above.

  Then, the electric winch 23 is actuated, the hanging wire 230 is gradually drawn out, the lifting body 3 is lowered together with the transport carriage 4 and the fire pump 5, and the wheels of the casters 41 of the transport carriage 4 are grounded to the traveling surface of the fire truck 9. The lifting / lowering body 3 is stopped at this height (see FIG. 6C). In this state, most or all of the loads of the transport carriage 4 and the fire pump 5 are supported by the wheels of the casters 41, and no load is applied to the carriage holding arm 31 or is reduced. ing.

  For this reason, although the heavy-duty firefighting pump 5 is loaded, friction force is not generated or reduced between the transport carriage 4 and the carriage holding arm 31, so that the transport carriage 4 is relatively It can be easily moved in the front-rear direction along the carriage holding arm 31. That is, by releasing the fixation of the transport carriage 4 that has been lowered to the height by the lock mechanism portion 314, the transport carriage 4 loaded with the fire pump 5 from the carriage holding arm 31 can be easily detached (retracted backward). (See FIG. 6D).

  After the carrier truck 4 loaded with the fire pump 5 is detached from the carriage holding arm 31 of the lifting body 3 and lowered from the loading platform 90, usually, the fire pump 5 is loaded on the carrier truck 4 and the desired location such as a water source. The fire pump 5 is used for fire extinguishing work. In addition, when passing the place which cannot move with the conveyance trolley | bogie 4, the fire pump 5 can be lowered | hung from the conveyance trolley | bogie 4, and an operator can also carry it by hand.

After the fire extinguishing work is finished, the fire pump 5 is loaded on the transport carriage 4 and moved to the location of the fire engine 9 (there is no transport truck 4 and fire pump 5) and moved on the running surface (ground). The carriage 4 is transferred so as to be fitted into the carriage holding arm 31 of the elevating body 3 without lifting the carriage 4.
As described above, the detachment and transfer of the transport carriage with respect to the carriage holding arm can be performed easily and safely with relatively light labor without the operator lifting the transport carriage 4 and the fire pump 5.

  Then, the electric winch 23 is operated to raise the elevating body 3 to a height that does not interfere with the movement of the moving table 2, and then the fixing of the moving table 2 by the fixing pin 13 is released. After releasing the fixing of the moving table 2, the moving table 2, the lifting body 3, the transport cart 4 and the fire pump 5 are integrally moved to the accommodation position of the fixed guide, and the moving table 2 is fixed by the fixing pins 13. Secure to the guide.

With reference to FIG. 7, the structure of the fire pump unloading apparatus A2 will be described.
The fire pump unloading device A2 employs a hydraulic cylinder 24 as a lifting drive means.

A pulley 240 is attached to the tip of the rod portion.

  Further, one end of the suspension wire 241 is fixed to the lower surface side of the upper frame 210 near the attachment position of the hydraulic cylinder 24. The suspension wire 241 is first hung on the pulley 240 at the tip of the rod portion of the hydraulic cylinder 24 so as not to loosen, and further hung on the pulley 211 fixed to the upper surface side of the upper frame 210 above. The other end is fixed to the center of the lower frame 306 of the elevating frame 30 lowered to the lowest part of the guide rods 214 and 215. In addition, in order to adjust the tension | tensile_strength of the suspension wire 241 suitably, an adjustment tool can also be provided.

According to this structure, the elevating frame 30 can be moved up and down by expanding and contracting the rod portion of the hydraulic cylinder 24. Further, in this structure, a dynamic pulley (pulley 240) is used, and the lifting / lowering stroke of the lifting / lowering body 3 suspended by the suspension wire 241 is approximately double that of the expansion / contraction stroke of the rod portion. Is to be obtained.
