Causes the luggage support frame 2 to descend against the push-up mechanism 4, the locking rod 28 contacts the upper right slope of the hook portion of the hook body 20, and the hook body 20 rotates counterclockwise about the pin 21 as a fulcrum. Then, as the luggage support frame 2 is further lowered, the locking plate 33 comes into contact with the upper surface of the claw portion 20 of the hook body 20 to rotate the hook portion of the hook body 20 in the clockwise direction as shown in FIG. As it descends, the hook part of the hook body 20 automatically captures the locking rod 28 by the urging force of the urging spring 29 and locks the luggage support frame 2 on the machine frame 1 and Maintain a state that prevents movement.

Next, the fixing mechanism 7 will be described.

The U-shaped locking hooks 37, 37 are provided on the lower surface rear surface of the vertical rods 9, 9 of the machine frame 1 so as to project the locking horizontal rods 35 which engage with the locking hooks 37, 37. The moving body B is erected on the lower part of the frame 34, and locking rings 38, 38 for restricting the left and right positions of the moving body B with respect to the load lifting device A are attached to the locking horizontal rod 35. When the horizontal rod 35 of the moving body B is locked to the locking hooks 37 and 37, and the lower surface of the load lifting and lowering device A and the upper surface of the moving body B are overlapped with each other, the upper cross rail of the load lifting and lowering device A is The locking male piece 39 projecting from the back side of the central portion of the lower surface of 11 is fitted into the locking receiving body 40 provided on the upper horizontal rod 36 of the vehicle frame 34 of the moving body B, and the luggage is pushed up and down by the T-shaped locking rod 42. The device A and the moving vehicle body B are provided so as to be fixed integrally.

The luggage lifting and lowering device A is erected on the ground, behind which the moving vehicle body B is lifted with the wheel 5 as a fulcrum and the moving vehicle body B is also erected on the ground, and is locked with the locking hooks 37, 37. While engaging the rings 38, 38, engage with the hooks of the engagement hooks 37, 37. Engage the horizontal rod 35 to overlap the back of the load lifting device A with the front of the moving vehicle B, and receive the engagement. The male piece 39 for locking the body 40 is inserted, and the T-shaped locking rod 42 integrally fixes the loading / unloading apparatus A and the moving vehicle body B.

[0031] When carrying a heavy load a such as a gas-filled cylinder, a case filled with a heavy object, or a bag body that is difficult for a person to easily carry by a truck, and store it in a truck when it is unloaded to the user. Take out the machine, remove the moving body B from the load lifting / lowering device A, and slant the load lifting / lowering device A onto the loading platform b.

In this case, it is important for safety to set the grounding part 15 and the locking part 16 firmly.

Next, an operator rolls, drags, or pushes the load a on the loading platform a to carry it to the load lifting and lowering device A, and depresses the foot pedal 24 to lock the lock mechanism 3. The luggage supporting frame 2 of the lifting and lowering device A for lifting and lowering the luggage a is put on the guide roller 44 and slowly lowered to support the luggage a on the luggage supporting frame 2 provided with the guard 45.

Since the load a is lowered by using the lifting force of the lifting mechanism 4 as a cushion due to the load of the load a, the load a does not drop suddenly, and the load supporting frame 2 on which the load a is quietly and stably placed descends to the bottom. However, the lock mechanism 3 is automatically locked.

The worker descends from the loading platform b, raises the load unloading device A to stand up, mounts the moving body B and uses the machine as a transport vehicle to carry it to the place of use, stands up the machine, and loads the baggage a to the predetermined position. Set it in place.

On the other hand, when carrying the load a, the load a is placed on the load supporting frame 2 of the load lifting and lowering device A, and the machine is used as a carrier to move to the cargo bed b of the truck. Standing up, the moving body B is detached, the device A for lifting and lowering the luggage is laid over the ground and the platform b, and the foot pedal 24 is stepped on to release the lock mechanism 3, the push-up mechanism 4 is activated, and the luggage support frame 2 Moves up.

At that time, the worker puts his / her hand on the luggage a and uses the inertia of the upward movement of the luggage a to push it up all at once onto the loading platform b by human power.

[Effect of device]

 Since the present invention is configured as described above, the luggage lifting and lowering device is placed and fixed on the moving vehicle body, the luggage to be carried is placed on the luggage support frame of the luggage lifting and lowering device, and the optimum equipment for carrying the luggage is carried. Move to the position as a transport vehicle, release the fixing mechanism, remove the luggage lifting and lowering device from the moving car body, cross the removed luggage lifting and lowering device to the place where you want to carry your luggage and the ground, and of the luggage support frame. The lock mechanism that prevents upward movement is released by depressing the foot pedal, and the luggage support frame that supports heavy luggage is pushed up by the lifting mechanism of the luggage lifting device, and the lifting force is increased. While using the inertia of pushing up, applying arm force to the luggage and easily pushing the luggage up to the bed of the truck as desired can be easily done manually, so I lifted it by hand as before. Freed from the heavy work that is carried on the shoulders, on the contrary, when unloading a heavy load from a high place, place the load on the luggage support frame of the loaded load lifting device to stably unload it against the lifting mechanism. In addition, since this machine can be used as a transport vehicle, it can be used to easily and easily move luggage, which makes it a highly practical luggage lifter.
