Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft sewage vehicles, and in particular relates to a water pipe guide device for a reel box of an aircraft sewage vehicle. Background Art

[0002] The aircraft sewage truck is a special ground equipment used to collect and transport the sewage discharged from the aircraft sewage tank and to add cleaning water to the aircraft.

[0003] The water filling pipe is connected to the sewage truck to flush the inner wall of the sewage unloading chamber when discharging sewage from the aircraft. Since the inner wall is flushed, the cleaning water pressure will be higher, and the recoil force exerted on the water filling pipe will be greater. Therefore, the water filling pipe will jump up and down due to the size of the recoil force when spraying water and stopping water. After a long period of use, the water filling pipe and the water inlet of the sewage truck will rupture, causing water leakage, thereby affecting the efficiency of the cleaning work.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the technical problem that the water pipe flushes the inner wall of the sewage discharge chamber when the sewage truck is connected to the aircraft to discharge sewage, the water pressure of the washing will be high because the inner wall is flushed, and the recoil force on the water pipe will be large. Therefore, the water pipe will jump up and down due to the size of the recoil force when the water is sprayed and stopped. After a long time of use, the water pipe and the water inlet of the sewage truck will be broken, causing water leakage, thereby affecting the efficiency of the cleaning work. The basic concept of the technical solution adopted by the utility model is:

[0009] As a preferred embodiment of the present invention, the rotation positioning mechanism includes a rotating seat rotatably connected to the top of the sewage truck, the top of the rotating seat is fixedly connected to the bottom of the guide frame, a positioning hole is provided on the outer wall of the rotating seat, a fixing plate is fixedly connected to the top of the sewage truck, a second sliding hole is provided on the outer wall of the fixing plate, a sliding rod is slidably connected to the inner wall of the second sliding hole, one end of the sliding rod is fixedly connected to the second connecting plate, the second connecting plate is fixedly connected to the second spring at one end close to the fixing plate, the second spring is fixedly connected to the outer wall of the fixing plate at one end away from the second connecting plate, the sliding rod is fixedly connected to the end away from the second connecting plate with a card protrusion, and the outer wall of the card protrusion is carded on the inner wall of the positioning hole.

[0010] As a preferred embodiment of the utility model, the guide frame is in an arc shape, the guide rollers are in a plurality, and the guide rollers form a group of two and are distributed on the inner and outer walls of the guide frame in a bilaterally symmetrical structure.

[0011] As a preferred implementation of the utility model, the inner wall of the limiting sliding groove fits snugly with the outer wall of the connecting rotating column.

[0012] As a preferred embodiment of the present invention, the inner wall of the jack is fitted closely to the outer wall of the plug rod, there are a plurality of jacks, and the jacks are evenly and equidistantly distributed on the outer wall of the guide frame.

[0017] When the guide frame needs to be rotated, the rotating seat can be directly rotated with greater force. When the rotating seat is rotated, the inner wall of the positioning hole will squeeze the card protrusion, and the squeezed card protrusion can drive the slide bar and the second connecting plate to move to one side. At the same time, the second spring will be stretched during the movement of the second connecting plate until the next positioning hole is moved to the position of the card protrusion. The second spring rebounds and makes the card protrusion re-engaged in the positioning hole. After continuously rotating to a suitable position, the positioning of the guide frame can be completed. In this way, even if the parking direction of the vehicle is opposite to one side of the aircraft, there is no need to readjust the direction of the vehicle. The direction of the guide frame can be directly rotated, which is convenient for the staff to use.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] like Figures 1 to 4 As shown, a guide device for adding water pipe to a reel box of an aircraft sewage truck comprises a sewage truck 1, a reel 2 arranged inside the sewage truck 1, a guide limiting mechanism 31 is arranged on the sewage truck 1, a rotation positioning mechanism 32 is arranged on one side of the guide limiting mechanism 31, the guide limiting mechanism 31 comprises a guide frame 311, a limit slide groove 312 is arranged on the inner and outer walls of the guide frame 311, a connecting rotating column 314 is movably connected to the inner wall of the limit slide groove 312, a guide roller 313 is fixedly connected to the end of the connecting rotating column 314 away from the limit slide groove 312, and a connecting rotating sleeve 314 is rotatably connected to the outer wall of the connecting rotating column 314. 15. A connecting rod 316 is fixedly connected to the outer wall of the top end of the connecting sleeve 315. A first sliding hole is provided on the outer wall of one end of the connecting sleeve 315 away from the connecting sleeve 315. A plug rod 317 is slidably connected to the inner wall of the first sliding hole. A first connecting plate 318 is fixedly connected to one end of the plug rod 317. A first connecting plate 318 is fixedly connected to one end of the first connecting plate 318 close to the connecting rod 316. An end of the first spring 319 away from the first connecting plate 318 is fixedly connected to the outer wall of the connecting rod 316. A plug hole 3110 is provided on the outer wall of the guide frame 311. The inner wall of the plug hole 3110 is snap-connected with the outer wall of the plug rod 317.

[0027] Furthermore, the guide frame 311 is in the shape of an arc, and the guide rollers 313 are in the number of two, and the guide rollers 313 are distributed on the inner and outer walls of the guide frame 311 in a left-right symmetrical structure, so that the water pipe can be passed through it to limit and guide the water pipe. At the same time, the guide rollers 313 can reduce the friction of the water pipe when passing through the guide frame 311.

[0028] Furthermore, the inner wall of the limiting slide groove 312 fits snugly with the outer wall of the connecting rotating column 314, thereby ensuring the fit of the guide roller 313 during the movement of the inner wall of the limiting slide groove 312, preventing shaking and causing unstable limiting of the water adding pipe.

[0029] Furthermore, the inner wall of the socket 3110 fits snugly with the outer wall of the plug rod 317, and there are a plurality of sockets 3110, which are evenly and equidistantly distributed on the outer wall of the guide frame 311, thereby ensuring the stability of the guide roller 313 after limiting the position, and further improving the limiting stability of the water adding pipe.

[0030] The rotation positioning mechanism 32 includes a rotating seat 321 rotatably connected to the top of the sewage truck 1, the top of the rotating seat 321 is fixedly connected to the bottom of the guide frame 311, and a positioning hole 322 is provided on the outer wall of the rotating seat 321, and a fixing plate 323 is fixedly connected to the top of the sewage truck 1, and a second sliding hole is provided on the outer wall of the fixing plate 323, and a sliding rod 324 is slidably connected to the inner wall of the second sliding hole, and one end of the sliding rod 324 is fixedly connected to a second connecting plate 325, and the second connecting plate 325 is fixedly connected to a second spring 326 at one end close to the fixing plate 323, and the second spring 326 is fixedly connected to the outer wall of the fixing plate 323 at one end away from the second connecting plate 325, and the sliding rod 324 is fixedly connected to a card protrusion 327 at one end away from the second connecting plate 325, and the outer wall of the card protrusion 327 is carded on the inner wall of the positioning hole 322.

[0031] Furthermore, an arc setting is opened at one end of the card protrusion 327 away from the sliding rod 324, and the outer wall of the card protrusion 327 fits well with the outer wall of the positioning hole 322, so that when the rotating seat 321 is rotated, it is only necessary to rotate the rotating seat 321 with force, making it easier to adjust the direction and convenient for the staff to use.

[0032] Furthermore, there are several positioning holes 322 , which are evenly and equidistantly distributed on the outer wall of the rotating seat 321 , so that the adjustment in different angles and directions can be satisfied, making the device more applicable and convenient for staff to use.

[0033] The implementation principle of the water supply pipe guide device of the aircraft sewage truck reel box of the present embodiment is as follows: first, the water supply pipe wound in the reel 2 is passed through the guide rollers 313 in the guide frame 311, so that the water supply pipe can be supported and guided. When facing water supply pipes of different specifications, the first connecting plate 318 is first pulled to drive the insertion rod 317 to move outward. During the movement of the first connecting plate 318, the first spring 319 will be driven to stretch, and the insertion rod 317 will be separated from the inner wall of the socket 3110, thereby releasing the limiting effect on the guide roller 313, and then the first connecting plate 318 is pulled left and right to drive the connecting plate 318 to move outward. The rod 316 and the connecting rotating column 314 move left and right. At this time, the connecting rotating column 314 will move left and right on the inner wall of the limiting slide groove 312, so that the distance between the two guide rollers 313 can be adjusted, so that water filling pipes of different specifications and types can be adapted. After the outer walls of the two guide rollers 313 are tightly attached to the outer wall of the water filling pipe, the first connecting plate 318 can be loosened. At this time, the first spring 319 can rebound and reset to drive the insertion rod 317 to be inserted into the socket 3110 to complete the positioning, so that the water filling pipe can be clamped and limited to prevent the water filling pipe from shaking after the cleaning water is connected to prevent water leakage.

[0034] When the guide frame 311 needs to be rotated, a greater force can be used to directly rotate the rotating seat 321. When the rotating seat 321 is rotated, the inner wall of the positioning hole 322 will squeeze the card protrusion 327, and the squeezed card protrusion 327 can drive the sliding rod 324 and the second connecting plate 325 to move to one side. At the same time, during the movement of the second connecting plate 325, the second spring 326 will be stretched until the next positioning hole 322 is moved to the position of the card protrusion 327, and the second spring 326 rebounds, so that the card protrusion 327 is re-engaged in the positioning hole 322. After continuously rotating to the appropriate position, the positioning of the guide frame 311 can be completed. In this way, even if the parking direction of the vehicle is opposite to one side of the aircraft, there is no need to readjust the direction of the vehicle. The direction of the guide frame 311 can be directly rotated, which is convenient for the staff to use.
