DETAILED DESCRIPTION

[0033] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0034] like Figure 1 , 2 As shown, the automatic hose retracting and releasing mechanism includes a horizontally arranged double-layer horizontal extending unit 1 and a left lifting unit 2 and a right lifting unit 3 installed on both sides of the double-layer horizontal extending unit 1, and a hydraulic reel unit 4 is installed on the left lifting unit 2 and the right lifting unit 3. The entire mechanism can be installed in a 2.5-meter-wide carriage. The mechanism is an extending lifting mechanism with a horizontal guide rail on the top, which saves the space occupied by the installation surface. More importantly, a maintenance space sufficient for people to pass through can be reserved in the middle of the mechanism.

[0035] like Figure 3 , 4 As shown, the automatic hose retracting mechanism can extend the reel out of the car and lower it to the ground, making it easy for people to take and put the drainage hose. The automatic hose retracting mechanism is welded to the car floor 5 using a support column 11. Depending on the installation environment, the entire mechanism can also be hung on the car ceiling using a hanging column 12 as a force support point for the entire mechanism.

[0036] like Figure 4 , 5 As shown, the double-layer horizontal extension unit 1 includes two groups of extension action outer guide rails 7 fixedly connected to the two ends of the reinforcing cross beam 14, and the two groups of extension action outer guide rails 7 are staggered in the upper and lower double layers, and the internal space is reasonably utilized. An extension cylinder 13 is installed inside the extension action outer guide rail 7, and the two ends of the extension cylinder 13 are respectively connected to the extension action outer guide rail 7 and the extension action inner guide rail 8, and one end of the extension action inner guide rail 8 extends into the extension action outer guide rail 7, and the two are adapted;

[0037] The extending cylinders 13 in the two sets of extending outer guide rails 7 are oriented in opposite directions, and the extending inner guide rails 8 in the two sets of extending outer guide rails 7 are respectively fixedly connected to the two extending frames 15, so that when the extending cylinders 13 are actuated, the extending frames 15 are pushed out of the car along the length direction of the extending outer guide rails 7.

[0038] like Figure 6 , 7 As shown, the inner guide rail 8 of the extending action and the extending frame 15 are fixed as a whole, and the extending frame 15 is installed with a lifting cylinder 9 and a lifting frame 16. The lifting frame 16 can be slidably suspended on the extending frame 15, and the two ends of the vertically arranged lifting cylinder 9 are respectively connected to the extending frame 15 and the lifting frame 16, so that when the lifting cylinder 9 is actuated, the lifting frame 16 can be driven to lift and reciprocate relative to the extending frame 15.

[0039] The lifting cylinders 9 and the lifting frames 16 on the two extending frames 15 form a left lifting unit 2 and a right lifting unit 3 respectively.

[0040] The hydraulic reel unit 4 is arranged on the lifting frame 16, and four hydraulic reel units 4 are fixed on a single side of the lifting frame. Each reel unit can reel in a 30-meter drainage hose, and there are a total of 8 hydraulic reel units on both sides of the whole mechanism.

[0041] In this way, when the whole set of mechanisms is folded up in the carriage, Figure 1 , 2 As shown, the double-layer horizontal extension unit 1 will be horizontally located above a plurality of hydraulic reel units 4, and the space occupied by the vertically arranged lifting cylinder in the lateral direction is also extremely small. Therefore, it not only saves the space occupied by the installation surface, but also allows more hoses to be accommodated in the car body. Moreover, considering the existence of the horizontally arranged extension cylinder 13, sufficient maintenance space for people to pass through can be reserved under the cylinder body.

[0042] When the hose needs to be released, Figure 3 , 4 As shown in 12 and 13, the extending cylinder 13 in the double-layer horizontal extending unit is first actuated to push out the extending frame, the lifting frame and the hydraulic reel unit laterally, and then the lifting cylinder in the left lifting unit 2 or the right lifting unit 3 vertically lowers the lifting frame and the hydraulic reel unit, waiting for the hydraulic reel unit to be activated.

[0043] like Figure 8 As shown, the hydraulic reel unit includes a rotating shaft 21, a side disc, a reel 18, a clutch mechanism and a rotation drive mechanism. The rotating shaft 21 is fixedly connected to the lifting frame 16. The side disc has two side discs, which are fixedly connected by the reel 18. The two side discs are rotatably mounted on the rotating shaft 21. The reel 18 is provided with a hose connector fixing plate 17 for fixing a quick connector at the end of the drainage hose.

[0044] The rotary drive mechanism is also mounted on the lifting frame 16 and connected to the side plate via a clutch mechanism. When the clutch mechanism is engaged, the rotary drive mechanism drives the reel 18 to rotate around the rotation axis 21 to achieve winding and releasing of the hose; and when the clutch is released, the reel 18 can rotate freely around the rotation axis 21 to facilitate manual retraction and release of the hose, ensuring barrier-free access to the hose.

[0045] The rotary drive mechanism includes a hydraulic motor 22, a pinion 23 and a large gear 20. The housing of the hydraulic motor 22 is fixedly mounted on the lifting frame 16, the pinion 23 is fixedly mounted on the output shaft of the hydraulic motor 22, and the large gear 20 is rotatably mounted on the rotating shaft 21 and is meshed with the pinion 23. The connection between the large gear 20 and the side plate is connected or disconnected by the clutch mechanism.

[0046] The clutch mechanism includes a positioning sleeve 24, an axle pin 25, a compression spring 26 and a clutch handle 27. The positioning sleeve 24 passes through the surface of the side plate, the axle pin 25 passes through the positioning sleeve 24, and a plurality of coupling holes for accommodating the axle pin 25 are opened on the surface of the large gear 20.

[0047] like Fig. 9 , 10 As shown in Figure 11, a mounting plate fixedly connected to the reel 18 is also provided inside the reel 18, the axle pin 25 passes through the mounting plate and is hinged to the L-shaped clutch handle 27, and the compression spring 26 is pressed between the mounting plate and the limiting convex ring in the middle of the axle pin 25, so that the axle pin 25 maintains a movement tendency to extend toward the position of the combining hole; when the clutch handle releases the axle pin to prepare to extend into the combining hole, the compression spring can ensure that it has a movement tendency, so that when the next combining hole rotates, it can quickly extend into the combining hole to complete the combination.

[0048] One end of the L-shaped clutch handle 27 is hinged to the shaft pin 25, and the middle part of the clutch handle 27 is connected to the mounting plate through a connecting rod, and the two ends of the connecting rod are respectively hinged to the clutch handle 27 and the mounting plate. In this way, the clutch handle 27 can be moved to pull the shaft pin 25 to reciprocate along the guide of the positioning sleeve 24. When the shaft pin 25 is inserted into the combination hole, the large gear and the reel move synchronously. When the shaft pin 25 leaves the combination hole, the large gear loses contact with the reel, and the reel can rotate freely.

[0049] There are many specific implementation ways of the utility model. The above is only the preferred implementation mode of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the protection scope of the utility model.
