As an important part of the automobile manufacturing industry, it promotes the progress and innovation of automobile technology.

[0003] Although the liquefied gas transport vehicle market is becoming mature, there are still certain defects in many aspects. At present, during the transportation of liquefied gas, liquefied petroleum gas cylinders need to be manually carried. The liquefied petroleum gas cylinders themselves are heavy and are very easy to collide during the transportation process. At the same time, workers may drag or drop bottles during transportation. There is also a risk of explosion in hot environments. Secondly, although manual transportation can meet daily distribution work, it cannot further improve distribution efficiency. Especially in hot weather, workers' work efficiency is lower and there is a risk of heat stroke. In cold weather, workers' efficiency is also low and there is a risk of frostbite. Based on this, an electric loading and unloading device for liquefied gas distribution vehicles is proposed to reduce the manpower burden, improve production efficiency, meet the growing needs of the market, and ensure efficiency and safety in the production and transportation process.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-Figure 4 The utility model provides a technical solution: an electric loading and unloading device for a liquefied gas distribution vehicle, comprising

[0038] N columns 1, N is an even number greater than or equal to 4, and the N columns 1 are evenly distributed on both sides of the interior of the carriage, and the top of the columns 1 on the same side is commonly fixed with a slide rail 2. Preferably, four columns 1 are provided, two of which are located on one side, and the four columns 1 are located at the four corners of the interior of the carriage. If the carriage is long and two columns 1 on one side are difficult to support the slide rail 2, six or eight columns 1 can be provided at this time, so that three or four columns 1 are used to support the slide rail 2 on one side to ensure the stable installation of the slide rail 2.

[0039] See Figure 1-Figure 4 as well as Figure 7 As shown, the electric loading and unloading device of the liquefied gas distribution vehicle also includes a hanger 7, a cantilever 3 and a hoist 4. The hanger 7 is arranged above the slide rail 2, and the hanger 7 can slide along the slide rail 2. The cantilever 3 is fixed to the lower end surface of the hanger 7. When the hanger 7 slides to the end of the car, the cantilever 3 extends 0.3-0.8 meters outside the car. The hoist 4 is installed below the cantilever 3. The hoist 4 includes a motor 41, a winding rod 42 and a support plate 43. The motor 41 is installed on the support plate 43, and the winding rod 42 is installed through a reducer. At the output end of the motor 41, a steel wire rope 5 is wound on the winding rod 42, and the free end of the steel wire rope 5 is hung with a hanger 6 for hanging a liquefied gas tank through a hook. A T-slot 11 is opened along the length direction on the lower end surface of the cantilever 3, and connecting strips 12 are symmetrically connected on both sides of the upper end surface of the support plate 43. A T-block 13 is fixed to the top of the connecting strip 12, and the T-block 13 is slidably fitted in the T-slot 11. By sliding the T-block 13 in the T-slot 11, the hoist 4 can slide along the length direction of the cantilever 3.

[0040] The above preferred Figure 1 As shown, when the hanger 7 slides to the end of the car, the cantilever 3 extends 0.5 meters outside the car. At this time, it is more convenient to use the hanger 6 to hang the liquefied gas tank, which can avoid being too close or too far from the car. Secondly, according to the different sizes of liquefied gas tanks, the length of the cantilever 3 extending outside the car can also be appropriately adjusted.

[0041] See Figure 4 and Figure 5 As shown, a slide groove 8 is provided on the upper end surface of the slide rail 2 along the length direction, and mounting plates 9 are fixed at both ends of the lower end surface of the hanger 7, and pulleys 10 that match the slide groove 8 are installed on the mounting plates 9.

[0042] See Figure 6 As shown, the hanger 6 includes a horizontal plate 61 , a hanging ring 62 is fixed at the middle of the upper end surface of the horizontal plate 61 , and a plurality of hooks 64 are installed at the lower end of the horizontal plate 61 .

[0043] In addition, the electric loading and unloading device is driven by the existing power supply system on the vehicle, and the investment cost of the existing equipment is low without adding too much extra equipment. It is operated by wireless remote control, which is convenient and fast. Specifically, a wireless remote control switch can be added in the vehicle's central control room to control the motor 41. Secondly, the entire set of devices can be disassembled, and the installation between the carriages can be fixed with bolts, which is convenient for daily flexible use and also conducive to daily maintenance of the equipment.

[0044] In addition, during specific production, special customized construction can be carried out according to the size of the vehicle model, with high flexibility to ensure that it is suitable for every type of transport vehicle.

[0045] The standard operating procedures of the electric loading and unloading device of the liquefied gas distribution vehicle are as follows:

[0046] 1. Push the hanger 7 to slide to the end of the carriage, at which point the cantilever 3 extends outside the carriage;

[0047] 2. Pull down the rack 6 and use the hoist 4 to lower the rack 6 to the bottom;

[0048] 3. Hang the gas cylinders at the appropriate points on the hanger 6 according to the number of cylinders to be hung (i.e., hang them using the hooks 64);

[0049] 4. Press the button of hoist 4 to lift the gas cylinder;

[0050] 5. Push the gas cylinder to slide on the cantilever 3 to the middle of the hanger 7;

[0051] 6. Push the hanger 7 to slide on the slide rail 2 to transport the gas cylinder to the placement position;

[0052] 7. Press the descend button to lower the gas cylinder to the desired position and remove the gas cylinder from the rack 6.

[0053] Example 2

[0054] The difference between this embodiment and the first embodiment is that, see Figure 6 As shown, a groove 63 is provided on the lower end surface of the horizontal plate 61 along the length direction, and a plurality of connecting rods 65 are connected to the inside of the groove 63. The upper end of the hook 64 is sleeved on the outside of the connecting rod 65, and the hooking directions of the two adjacent hooks 64 are opposite. The opposite hooking directions make it easier for the two hooks 64 to be more evenly stressed when hooking the liquefied gas cylinder.

[0055] Among them, six hooks 64 are preferably provided on each horizontal board 61, and two hooks 64 form a group from one end of the horizontal board 61 to the other end, so that three liquefied gas cylinders can be transported at one time, which improves labor efficiency and is a great improvement compared with the previous manual transportation of one bottle at a time.
