[0002] A cryogenic liquid filling device is a device specifically used to fill cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, etc.) into tank trucks or specific containers. This device usually includes key components such as storage tanks, pumping systems, control systems, pipelines and connectors to ensure that the cryogenic liquid can maintain a stable temperature and pressure during the filling process, while achieving efficient and safe filling operations.
[0003] In the prior art, the conventional method of filling a car with cryogenic liquid (liquid oxygen, liquid nitrogen, liquid argon, etc.) is to connect a common hose with the transport tank truck to the liquid receiving port of the storage tank for filling. Since the temperature of the cryogenic liquid is relatively low (about -190°C), during the filling process, the common hose will frost and cool down, causing a loss of cooling capacity. Since the hose temperature is extremely low, it may cause frostbite accidents during the filling process and the process of removing the hose after filling. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 - Figure 5 , the utility model provides a technical solution:
[0024] See also Figure 1 - Figure 5 The present invention shows an energy-saving and labor-saving low-temperature liquid filling device for a vehicle, comprising a concrete pier 1, a hanging column 8 is rotatably connected to the concrete pier 1, a hanging beam 10 is installed on the top of the hanging column 8, a chain rope 9 is arranged on the hanging beam 10, a counterweight iron bucket 4 is fixedly installed on one end of the chain rope 9, and a hook 11 is fixedly installed on the other end of the chain rope 9.
[0025] Remove the stop pin 5, connect the vacuum hose 21 to the hook 11, and the staff hold and rotate the operating handle 7 to rotate the suspension column 8 and the suspension beam 10 to a suitable angle. The counterweight iron barrel 4 is filled with stones and bricks to offset the weight of the vacuum hose 21. At the same time, a small hole is opened at the bottom of the counterweight iron barrel 4 for rainwater discharge. This makes it easier and more labor-saving for the operator to take the vacuum hose 21 to connect the tank truck interface, making it easier and more labor-saving for the operator to operate when filling the truck, thereby reducing the number of operators and saving labor costs to a certain extent.
[0026] See also Figure 2 A pre-buried steel plate 2 is installed on the top of the concrete pier 1, a hanger leg 3 is welded on the top of the pre-buried steel plate 2, and a hanging column 8 is rotatably connected to the hanger leg 3.
[0027] The arrangement of the embedded steel plate 2 and the hanger legs 3 enhances the stability and bearing capacity of the overall structure. The combination of the concrete pier 1 and the embedded steel plate 2 makes the structure stronger and can withstand greater pressure and tension. The connection between the hanger legs 3 and the hanging column 8 provides additional support for the structure and increases the stability of the overall structure.
[0028] See also Figure 2 An operating handle 7 is fixedly mounted on the outer wall of the hanging column 8, an upper plug plate 6 is welded on the hanging column 8, and a latch hole is opened on the upper plug plate 6.
[0029] The operating handle 7 provides a gripping point, and the staff can rotate the hanging column 8 by grasping the operating handle 7 to adjust it to a suitable position. The upper plug plate 6 and the stop pin 5 cooperate with each other to help the hanging column 8 to be better positioned.
[0030] See also Figure 2 The ends of the hanging beam 10 are opened, the middle is connected, and the chain rope 9 passes through the middle of the hanging beam 10.
[0031] The chain rope 9 directly passes through the middle of the hanging beam 10, without the need for additional connectors or fixing devices, thereby simplifying the installation process. At the same time, this design also facilitates subsequent disassembly and replacement operations and improves work efficiency.
[0032] See also Figure 3 A stop pin 5 is provided on one side of the hanging column 8, a limit plate is installed on the stop pin 5, and the stop pin 5 is plugged into a pin hole matched therewith.
[0033] At the same time, a small limit plate is welded in the middle of the stop pin 5 to control the vertical position of the stop pin 5 to prevent the stop pin 5 from sliding down too much, causing the tail of the stop pin 5 to touch other structures, making it inconvenient to remove the stop pin 5 later. After the stop pin 5 is removed, the hanging column 8 can be rotated. When the hanging column 8 is rotated to the desired position, the stop pin 5 can be inserted to lock the hanging column 8. At this time, the hanging column 8 will not rotate at will due to the contact of external force.
[0034] See also Figure 2 and Figure 4 A lower support sleeve 14 is installed on the top of the embedded steel plate 2, a pipe cap 15 is installed inside the lower support sleeve 14, a rain shield 12 is installed at the connection between the lower support sleeve 14 and the pipe cap 15, and a screw plug 13 is threadedly connected to the outer wall of the lower support sleeve 14.
[0035] The embedded steel plate 2 is used as a basis for connecting, fixing or reinforcing other components, and the lower support sleeve 14 thereon provides a stable supporting structure. The threaded connection mode of the screw plug 13 enhances the firmness of the connection and prevents loosening and falling off.
[0036] See also Figure 1 A plurality of support beams 19 are fixedly installed on the top of the hanger leg 3, an upper support plate 16 is fixedly installed on one side of the support beam 19, a lower pin hole 17 is opened on the upper support plate 16, and an upper support sleeve 18 is fixedly installed on the upper support plate 16.
[0037] The upper support plate 16 and the bracket cross beam 19 play a supporting and connecting role. When the suspension column 8 is rotating, the upper support sleeve 18 and the upper support plate 16 can play a certain supporting role. The lower pin hole 17 cooperates with the stop pin 5 to achieve a better positioning effect when the suspension column 8 is rotating horizontally.
[0038] See also Figure 1 and Figure 5 A vacuum hose 21 is lapped on the hook 11, and a plurality of sliding pallet trucks 20 are fixedly installed on the outer wall of the concrete pier 1.
[0039] The design of the sliding trolley 20 is exquisite and practical. The bottom of the sliding trolley is equipped with a pulley, which can slide easily on the ground, greatly reducing the direct contact between the vacuum hose 21 and the ground. When dragging the vacuum hose 21, the trolley bears most of the weight of the vacuum hose 21, so that the vacuum hose 21 remains stable during the movement and avoids wear and tear caused by friction. The sliding trolley 20 also has an adjustable function, which can be flexibly adjusted according to the length and diameter of the vacuum hose 21 to ensure that the vacuum hose 21 is firmly and reliably fixed on the pipe rack. This not only improves the safety of the vacuum hose 21, but also facilitates the use and maintenance of the operator. By using the sliding trolley 20 as the pipe rack of the vacuum hose 21, we have successfully reduced the risk of damage to the vacuum hose 21 during the dragging process and increased the service life of the vacuum hose 21. At the same time, this also reduces the production interruption and maintenance costs caused by damage to the vacuum hose 21, providing a strong guarantee for the continuous and stable operation of the enterprise.
[0040] Working principle: remove the stop pin 5, connect the vacuum hose 21 to the hook 11, and the staff hold and turn the operating handle 7 to rotate the suspension column 8 and the suspension beam 10 to a suitable angle. The counterweight iron barrel 4 is filled with stones and bricks to offset the weight of the vacuum hose 21. At the same time, a small hole is opened at the bottom of the counterweight iron barrel 4 for rainwater discharge. It is easier and more labor-saving for the operator to take the vacuum hose 21 to connect the tank truck interface, and it is easier and more labor-saving for the operator to operate when filling the truck, thereby reducing the number of operators and saving labor costs to a certain extent.
