Description

Technical Field

[0001] This utility model relates to the field of refueling hose technology, and in particular to a new refueling hose winding protection device for tank-type aircraft refueling trucks. Background Technology

[0002] Tank refueling trucks are specialized vehicles designed to provide fuel refueling services for aircraft. They integrate functions such as fuel storage, transportation, metering, and pressurized refueling, and are one of the core pieces of equipment for airport ground support. When aircraft need to refuel, tank refueling trucks assist in the refueling process, and the refueling hoses are the important channels connecting the refueling truck and the aircraft for fuel transfer.

[0003] In existing tank-type aircraft refueling trucks, one end of the refueling hose connects to the fuel delivery system on the truck, while the other end connects to the aircraft's refueling port via a refueling connector, serving to deliver aviation fuel. However, the hose is prone to swaying when retracting or extending, causing the cycloidal motor to move continuously and failing to effectively protect the hose. Furthermore, there is no proper limiting mechanism during hose retraction; the pressure connector on the hose can easily collide with the roller frame when retracted directly, leading to damage to the pressure connector.

[0004] The information disclosed above in this background section is merely for enhancing understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a new refueling hose rewinding and protection device for tank-type aircraft refueling trucks, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A novel refueling hose rewinding and protection device for a tank-type aircraft refueling truck includes a first mounting base, a refueling hose, and a second mounting base. Each of the first and second mounting bases has a set of screw holes at the front and rear of one corresponding end. Each of the first and second mounting bases has a support device fixedly installed at one corresponding end. A limit device is slidably installed at one corresponding end of the first and second mounting bases, and the refueling hose is inserted and installed at the front end of the limit device.

[0008] Preferably, the limiting device includes a first slider and a second slider. A first limiting roller is rotatably mounted between the first and second sliders. Two mounting screws are installed at corresponding ends of the first and second sliders. A first sliding groove is formed in the middle of the upper end of the first mounting base, and a second sliding groove is formed in the middle of the lower end of the second mounting base. The first slider is slidably mounted in the first sliding groove, and the second slider is slidably mounted in the second sliding groove. By loosening the mounting screws on the first and second sliders, the first slider can be slidably adjusted on the first mounting base, and the second slider can be slidably adjusted on the second mounting base, thereby allowing the distance between the two first limiting rollers to be appropriately adjusted according to the needs of the oiling hose.

[0009] Preferably, the support device includes a first support frame and a second support frame. A second limiting roller is rotatably mounted between the left and right inner walls of the first and second support frames. The first and second support frames are respectively fixedly mounted at the upper front and upper rear of the first mounting base. The second limiting roller and the two first limiting rollers can limit the movement of the refill hose, preventing it from shaking. Furthermore, the limiting roller can rotate with the refill hose as it is wound up, reducing wear between the refill hose and the limiting roller.

[0010] Preferably, a baffle is fixedly installed on the outer surface of the refueling hose. The baffle design on the outer surface of the refueling hose allows it to block the refueling hose and its pressure connector at the two first-position limit rollers during hose retraction, preventing the pressure connector from colliding with the first-position limit rollers.

[0011] Preferably, the mounting screws are positioned vertically corresponding to the screw holes.

[0012] Preferably, the length of the baffle is the same as the length of the first chute.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By designing a baffle on the outer surface of the refueling hose, the refueling hose and its pressure connector can be blocked at the two No. 1 limit rollers when the refueling hose is retracted, thus preventing the pressure connector from colliding with the No. 1 limit rollers.

[0015] 2. When using the refueling hose, connect one end of the hose to the fuel delivery system on the refueling truck, and the other end passes through the two No. 1 limit rollers and is connected to the aircraft's refueling port through the refueling connector. When the refueling hose is retracted, the No. 2 limit roller on the support device and the two No. 1 limit rollers can limit the refueling hose to prevent it from shaking. Moreover, the limit rollers can also rotate with the refueling hose as it is retracted, reducing wear between the refueling hose and the limit rollers.

[0016] 3. By loosening the mounting screws on slider one and slider two, slider one can slide and adjust on mounting base one, and slider two can slide and adjust on mounting base two. This allows the distance between the two limit rollers to be adjusted appropriately according to the needs of the lubrication hose. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4 As shown, a new refueling hose rewinding protection device for a tank-type aircraft refueling truck includes a first mounting base 1, a refueling hose 4, and a second mounting base 5. Each of the first mounting base 1 and the second mounting base 5 has a set of screw holes 6 at the front and rear of one corresponding end. Each of the first mounting base 1 and the second mounting base 5 has a support device 3 fixedly installed at one corresponding end. The first mounting base 1 and the second mounting base 5 are slidably mounted with a limit device 2 at one corresponding end. The refueling hose 4 is inserted and installed at the front end of the limit device 2.

[0026] The limiting device 2 includes a first slider 20 and a second slider 21. A first limiting roller 22 is rotatably mounted between the first slider 20 and the second slider 21. Two mounting screws 23 are installed at one end of each slider 20 and the second slider 21. A first sliding groove 24 is opened in the middle of the upper end of the first mounting base 1, and a second sliding groove 25 is opened in the middle of the lower end of the second mounting base 5. The first slider 20 is slidably installed in the first sliding groove 24, and the second slider 21 is slidably installed in the second sliding groove 25. The mounting screws 23 correspond vertically to the screw holes 6. By loosening the mounting screws 23 on the first slider 20 and the second slider 21, the first slider 20 can slide and adjust on the first mounting base 1, and the second slider 21 can slide and adjust on the second mounting base 5. Thus, the distance between the two first limiting rollers 22 can be appropriately adjusted according to the needs of the oiling hose 4.

[0027] The support device 3 includes a first support frame 30 and a second support frame 31. A second limiting roller 32 is rotatably mounted between the left and right inner walls of the first support frame 30 and the second support frame 31. The first support frame 30 and the second support frame 31 are respectively fixedly mounted at the front and rear of the upper end of the first mounting base 1. The second limiting roller 32 and the two first limiting rollers 22 can limit the movement of the glue hose 4, preventing it from shaking. Moreover, the limiting rollers can rotate as the glue hose 4 is wound up, reducing wear between the glue hose 4 and the limiting rollers.

[0028] A baffle 40 is fixedly installed on the outer surface of the refill hose 4; the length of the baffle 40 is the same as the length of the first chute 24. The refill hose 4 passes through the two first limit rollers 22, and the design of the baffle 40 on the outer surface of the refill hose 4 is such that when the refill hose 4 is retracted, it can block the refill hose 4 and its pressure connector at the two first limit rollers 22, preventing the pressure connector from colliding with the first limit rollers 22, and the length of the baffle 40 is longer than the first limit rollers 22.

[0029] It should be noted that this utility model is a new type of refueling hose rewinding protection device for tank-type aircraft refueling trucks. When in use, one end of the refueling hose 4 is connected to the fuel delivery system on the refueling truck, and the other end passes through two first-level limiting rollers 22 and is connected to the aircraft's refueling port via a refueling connector. When the refueling hose 4 is retracted, the second-level limiting roller 32 on the support device 3 and the two first-level limiting rollers 22 can limit the refueling hose 4, preventing it from shaking. Furthermore, the limiting rollers can rotate along with the refueling hose 4 as it is rewound, reducing the friction between the refueling hose 4 and the limiting rollers. Wear and tear. In addition, the design of the baffle 40 on the outer surface of the refill hose 4 can block the refill hose 4 and its pressure connector at the two first limit rollers 22 when the refill hose 4 is retracted, so as to prevent the pressure connector from colliding with the first limit rollers 22. At the same time, by loosening the mounting screws 23 on the first slider 20 and the second slider 21, the first slider 20 can slide and adjust on the first mounting seat 1, and the second slider 21 can slide and adjust on the second mounting seat 5. Thus, the distance between the two first limit rollers 22 can be appropriately adjusted according to the needs of the refill hose 4.
