Detailed Implementation

[0020] Example 1

[0021] like Figures 1 to 5As shown, a vehicle-mounted self-loading gas cylinder holder includes a pallet frame 1 on which gas cylinders are stored. The pallet frame 1 is slidably mounted on a lifting fork 2, and has the freedom to move along the length of the lifting fork 2. The lifting fork 2 is mounted on a lifting frame 3, and has the freedom to move along the height of the lifting frame 3. Multiple casters 7 are mounted on the bottom of the pallet frame 1, and multiple wheels 18 are mounted on the bottom of the lifting frame 3. The wheels 18 drive the entire holder to move, and the casters 7 facilitate the movement of the pallet frame 1. During loading, the lifting fork 2 moves upward on the lifting frame 3, causing the pallet rack 1 and the gas cylinder on the pallet rack 1 to move upward. When the bottom height of the caster wheel 7 is the same as the height of the truck's cargo box floor, it pushes the pallet rack 1 to move on the lifting fork 2, so that the pallet rack 1 can carry the gas cylinder into the truck bed without the need for additional forklifts or cranes. In special environments or emergency situations, the loading of gas cylinders and pallet rack 1 can be achieved. Compared with conventional gas cylinder racks, it only increases the footprint and weight slightly, and has virtually no impact on transportation capacity.

[0022] Example 2

[0023] Based on Example 1, such as Figure 1 and Figure 2 As shown, the top surface of the pallet frame 1 has several limiting holes. The bottom of the gas cylinder is placed in the limiting holes. A railing 4 is fixed to the top of the pallet frame 1. A loading / unloading window 5 is provided on one side of the railing 4. A stop bar 6 is provided in the loading / unloading window 5. One end of the stop bar 6 is hinged to the railing 4, and the other end is connected to the railing 4 through a pin. The stop bar 6 is rotatably connected to the railing 4 through a rotating shaft. The axis of the rotating shaft is horizontal. A insertion hole is provided on the top of the end of the stop bar 6 away from the rotating shaft. A pin hole is provided on the top surface of the railing 4 away from the rotating shaft. The pin passes through the insertion hole and is inserted into the pin hole, thereby installing the stop bar 6 on the railing 4. The railing 4 works with the stop bar 4 to block the gas cylinder and prevent it from falling off the pallet frame 1. When loading the gas cylinder, the pin is removed, the stop bar 6 is rotated to open the loading / unloading window 5, and the gas cylinder is placed in the limiting hole. The position of the gas cylinder is limited by the limiting hole. Finally, the stop bar 6 is installed to work with the railing 4 to further limit the position of the gas cylinder.

[0024] Example 3

[0025] Based on Example 2, such as Figures 1 to 3As shown, the lifting fork 2 includes a lifting fork frame 10, a vertical slider 8, and a horizontal slide rail 9. The lifting fork frame 10 is provided with two horizontal slide rails 9 spaced apart in the horizontal direction. The vertical slider 8 is fixed on the lifting fork frame 10 and slidably mounted on the lifting frame 3. The outer wall of the horizontal slide rail 9 is provided with a groove 11 extending along its own length. A slider 12 is slidably fitted in the groove 11. The slider 12 is fixedly connected to the pallet frame 1. The movement of the vertical slider 8 on the lifting frame 3 drives the lifting fork 2 to move up and down in the vertical direction, thereby moving the pallet frame 1 and the gas cylinders on it to complete the loading and unloading operations. The slider 12 is L-shaped, with one end slidingly fitted in the groove 11 and the other end fixed on the pallet frame 1, so that the pallet frame 1 can move horizontally on the lifting fork 2 to complete the loading and unloading operations.

[0026] Example 4

[0027] Based on Example 3, such as Figures 1 to 4As shown, the sidewall of the slide 11 has multiple insertion holes 13 along the length of the horizontal slide rail 9. The sidewall of the slider 12 has a through hole 14 extending horizontally. A limiting pin passes through the through hole 14 and is inserted into the insertion hole 13 to connect the horizontal slide rail 9 to the pallet frame 1. A lead screw 15 is vertically mounted on the lifting frame 3, and the lead screw 15 is rotatably connected to the lifting frame 3. A lead screw slider 16 is threaded onto the lead screw 15, and a vertical slider 8 is fixed on the lead screw slider 16. A motor 17 is mounted on the lifting frame 3, and the motor 17 is connected to the gear set for transmission. The lead screw 15 and the gear set include a meshing first bevel gear and a second bevel gear, which are respectively mounted on the output shaft of the lead screw 15 and the motor 17. The motor 17 drives the lead screw 15 to rotate through the gear set. The rotational freedom of the lead screw slider 16 is restricted by the sliding installation of the lifting fork 2 on the lifting frame 3, so that the lead screw slider 16 drives the vertical slider 8 to move linearly along the axis of the lead screw 15. When loading, the lifting fork 2 drives the pallet frame 1 to move upward, so that the bottom of the caster wheel 7 is level with the floor of the truck bed, pushing the pallet frame 1 upward. The pallet frame 1 is moved to the center of gravity (center) inside the truck bed. Then, the limiting pin is simultaneously inserted into both the through hole 14 and the insertion hole 13, connecting the pallet frame 1 and the lifting fork 2. Next, the motor 17 reverses direction. At this time, the positions of the pallet frame 1, the lifting fork 2, and the lead screw slider 16 remain unchanged, causing the lifting frame 3 to move upwards to the height of the truck bed. The lifting frame 3 is then pushed, and the limiting pin is removed, resetting the pallet frame 1. The entire retainer is moved to the designated position within the truck bed. Finally, the traveling wheels 18 and the swivel wheels 7 are braked, ensuring the retainer remains stable within the truck bed. For unloading, the same procedure applies. The lifting frame 3 is moved to the edge of the truck bed, and then the pallet frame 1 is moved so that its center is inside the truck bed. The pallet frame and lifting fork 2 are fixed with limit pins, and the lifting frame 3 is moved outside the truck bed. The position of the lifting frame 3 is stabilized by the pallet frame 1 and the gas cylinder. Then the motor 17 is started. Due to its own weight, the lifting frame 3 moves first at the position of the lifting fork 2, causing it to move downwards and touch the ground. Then the limit pins are removed, and the pallet frame 1 is removed from the truck bed, thus completing the unloading of the retainer.
