Description

Technical Field

[0001] This utility model relates to the field of loading arm technology, and in particular to a liquid-heated pneumatic loading arm for loading vehicles. Background Technology

[0002] An arm is a retractable hose used for loading and unloading liquids, such as oil and water, at oil and chemical terminals. It comes in various types and offers advantages over older flexible hoses, including higher safety and greater flexibility.

[0003] Most modern loading arms are single-pipe structures, which are susceptible to changes in ambient temperature, including low temperatures where the flow rate of the medium inside the pipe decreases. In severe cases, the medium may freeze, causing blockage. Current solutions rely on external heat sources to heat the pipes. However, since operators cannot accurately locate the fault within the pipe, the heating location is uncertain, leading to a certain probability of ineffective heating. Furthermore, heat source heating cannot be maintained, requiring continuous heating of the pipes, which increases the workload.

[0004] Based on this, a liquid-heated pneumatic loading arm for vehicle loading is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid-heated pneumatic loading arm for vehicle loading in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid-heated pneumatic loading arm includes a fixed column, a delivery pipe and a first pipe connected to the fixed column, a second pipe connected to one end of the first pipe, an injection pipe connected to the second pipe, a heating and insulation component for heating the loading arm connected to the second pipe, and a fixing mechanism for fixing the insulation component connected to the fixed column.

[0008] Preferably, the insulation component includes an insulation pipe, a corrugated pipe is connected to the insulation pipe, and a sealing ring and a connecting piece are connected to one end of the corrugated pipe.

[0009] Preferably, the sealing ring has a venting groove.

[0010] Preferably, the fixing mechanism includes a connecting rod, one end of which is connected to a rotating ring, the rotating ring being rotatably connected to a fixing column, a steam pipe being connected to the connecting rod, a positioning rod being connected to the connecting rod, and a screw being connected to the upper end of the positioning rod.

[0011] Preferably, a limiting ring is connected to the fixed post.

[0012] Preferably, a second limiting ring is connected to the positioning rod, a connecting groove is provided on the positioning rod, a fixing rod is connected in the connecting groove, and the fixing rod is connected to the limiting block by a spring.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts an insulated pipe structure to heat and insulate the loading arm, so that the internal medium is heated in the first pipe. When the medium flows into the second pipe and the injection pipe, the medium inside the pipe will heat the second pipe and the injection pipe. Furthermore, the insulation range can be improved by setting a corrugated pipe.

[0015] 2. This application adopts a positioning rod structure, which utilizes a positioning ring to quickly complete the connection between one end of the insulation pipe and the steam pipe, thereby improving the convenience of the connection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A liquid-heated pneumatic loading arm includes a fixed post 1, a delivery pipe 5 and a first pipe 2 connected to the fixed post 1, a second pipe 3 connected to one end of the first pipe 2, a filling pipe 4 connected to the second pipe 3, and a heating and insulation component for heating the loading arm connected to the second pipe 3. A fixing mechanism for fixing the insulation component is connected to the fixed post 1.

[0024] Specifically, such as Figure 1 As shown, the insulation component includes an insulation pipe 10, and a corrugated pipe 11 is connected to the insulation pipe 10. The corrugated pipe 11 can be stretched to cover the entire pipe 12 structure. One end of the corrugated pipe 11 is connected to a sealing ring 12 and a connecting piece 13. The sealing ring 12 is used to ensure the sealing of the insulation pipe 10 connection.

[0025] Specifically, such as Figure 2 As shown, a venting groove 16 is provided on the sealing ring 12. By setting the venting groove 16, steam can be discharged and blockage can be avoided. At the same time, the small-diameter venting groove 15 can also reduce the rate of heat loss.

[0026] Specifically, such as Figure 3 As shown, the fixing mechanism includes a connecting rod 8, one end of which is connected to a rotating ring 7, which is rotatably connected to the fixing column 1. A steam pipe 9 is connected to the connecting rod 8, and a positioning rod 17 is connected to the connecting rod 8. A screw 14 is connected to the upper end of the positioning rod 17, and the screw 14 is threaded onto the positioning rod 17.

[0027] Specifically, such as Figure 1 As shown, a limit ring 6 is connected to the fixed column 1, and the connection position of the rotating ring 7 is stabilized by setting the limit ring 6.

[0028] Specifically, such as Figure 3 As shown, a limiting ring 18 is connected to the positioning rod 17, and a connecting groove 19 is provided on the positioning rod 17. A fixing rod 20 is connected in the connecting groove 19. The fixing rod 20 is connected to the limiting block 15 through the spring 21. By setting the structure of the limiting block 15 and the spring 21, a quick connection between one end of the heat preservation pipe 10 and the steam pipe 9 can be realized.

[0029] In summary, the liquid-heated pneumatic loading arm provided in this embodiment, when heating of the loading arm is required, connects one end of the insulation pipe 10 to the steam pipe 9, connects one end of the connecting piece 13 to the positioning rod 17 with a screw 14, presses the limiting block 15 at the lower end of the positioning rod 17, and simultaneously inserts the positioning rod 17 into the connecting rod 8. Then, steam is introduced into the insulation pipe 10 through the steam pipe 9 to heat the pipe 10, ensuring that the transport medium does not become blocked when flowing through the loading arm.
