AI Technical Summary
The existing electric hose reels used for water supply on high-speed railways cannot precisely control the stop position when winding up the hose, resulting in large tensile forces at the connection between the hose and the connector, which reduces the service life of the hose.
Design a hose reel for water supply on high-speed trains. It uses a drive motor, transmission components, and elastic elements in conjunction with a distance sensor. The reeling stops when the upper support plate is aligned with the distance sensor. The elastic force of the elastic element ensures that the hose interface is precisely locked at the limit port, avoiding pulling force.
It enables complete retraction of the hose with minimal pulling force at the interface, extending the hose's lifespan and simplifying the operation process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of reel technology, and in particular to a reel for water supply to high-speed railways. Background Technology
[0002] High-speed rail stations typically require the installation of hose reels for winding hoses. These reels are used to replenish coolant for high-speed trains upon arrival. Based on their power source, these reels are categorized as manual or electric. Electric reels automatically wind up the hoses electrically. Current electric reels are controlled by a switch to start and stop at a specified length. However, for hoses used for water supply on high-speed trains, the hose is fully retracted after water supply is complete, eliminating the need to stop at different lengths. Using a switch would be cumbersome. If the reel is closed prematurely, the hose is not fully retracted, leaving the connector at the end hanging outside, resulting in significant tension on the hose. Conversely, if the reel is closed late, the connector at the end is already stuck in the reel's locking mechanism, while the motor continues winding, again exerting significant tension on the connection between the hose and the connector, thus reducing the hose's lifespan. Therefore, a reel with automatic winding and stopping mechanism suitable for high-speed rail water supply needs to be designed. Utility Model Content
[0003] To address the technical problem that existing automatic hose reels can only be controlled by a switch to start and stop, which can easily lead to improper timing of the winding stop, causing excessive tensile force at the connection between the hose and the connector, and reducing the service life of the hose, this utility model provides a hose reel for high-speed rail water supply to solve the above problems.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a reel for water supply to high-speed railways, including a reel body, an output fixing seat, a drive motor and a transmission assembly. The reel body is used to wind a hose. The drive motor drives the reel body to rotate through the transmission assembly. The output fixing seat includes two side plates, a lower support plate located between the two side plates, an upper support plate, and an elastic element connecting the lower support plate and the upper support plate. The upper support plate has a limiting port for limiting the interface of the hose. A distance sensor is provided on one of the side plates. The lower support plate is fixedly connected to the side plate. When the upper support plate is directly opposite the distance sensor, the drive motor stops.
[0005] In an optional embodiment of this utility model, the upper support plate is slidably engaged with the side plate, and the slide plate has a groove for the upper support plate to reciprocate up and down.
[0006] In an optional embodiment of this utility model, one end of the upper support plate is hinged to the side plate on a rotation axis, and the other end of the upper support plate is connected to an elastic element.
[0007] In an optional embodiment of this utility model, one end of the upper support plate connected to the elastic element is provided with a mounting hole, the guide post passes through the mounting hole and is connected to the lower support plate, and the elastic element is sleeved on the guide post.
[0008] In an optional embodiment of this utility model, the upper support plate includes a flat plate and a baffle extending downward from the flat plate. When the upper support plate moves in the direction of the lower support plate, the baffle is directly opposite the distance sensor.
[0009] In an optional embodiment of this utility model, a plurality of rollers are provided around the limiting port.
[0010] In an optional embodiment of this utility model, the transmission assembly includes a driving sprocket, a driven sprocket, and a chain. The driving sprocket is connected to a drive motor, the driven sprocket is connected to the center of the reel body, and the chain connects the driving sprocket and the driven sprocket.
[0011] In an optional embodiment of this utility model, the two ends of the reel body are rotatably connected to a frame, and the side plate is fixed on the frame.
[0012] In an optional embodiment of this utility model, the frame includes a main panel located at both ends of the reel body, a rear connecting plate and a front mounting plate connecting the two main panels and located on the front and rear sides of the main panels, the drive motor is fixed on the front mounting plate, and the side plate is located above the front mounting plate.
[0013] The beneficial effects of this utility model are:
[0014] (1) By setting the upper support plate to move, the upper support plate moves downward when it is subjected to the pressure of the hose interface. When it drops to the height of the distance sensor, the controller sends a stop signal to the drive motor, and the hose stops winding. At this time, the interface is just stuck at the limit port. Due to the elastic force of the elastic element, there will not be too much pulling force at the connection between the hose and its interface. The hose can be completely retracted, and the hose can be prevented from being damaged by force.
[0015] (2) The upper support plate in this utility model uses rotational motion to complete the sensing. Compared with linear lifting, it is easier to cause motion deformation. It does not require a large force to make the upper support plate rotate, thus reducing the driving force requirement. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] Example 1
[0026] like Figures 1-3 As shown, a water supply reel for high-speed rail includes a reel body 1, an output fixing base 2, a drive motor 3, and a transmission assembly 4. The reel body 1 is used to wind a hose. The drive motor 3 drives the reel body 1 to rotate through the transmission assembly 4. The output fixing base 2 includes two side plates 201, a lower support plate 202 located between the two side plates 201, an upper support plate 203, and an elastic element 204 connecting the lower support plate 202 and the upper support plate 203. The upper support plate 203 has a limiting port 5 for limiting the interface of the hose. A distance sensor 6 is provided on one of the side plates 201. The lower support plate 202 is fixedly connected to the side plate 201. When the upper support plate 203 is directly opposite the distance sensor 6, the drive motor 3 stops.
[0027] The drive motor 3 in this invention is a unidirectional motor used for winding up the hose.
[0028] like Figure 4 As shown, the reel body 1 consists of two discs 101 and a cylinder 102 located between the two discs 101. The hose is wound around the cylinder 102. One end of the reel is provided with a rotating shaft. An external connector is installed on the rotating shaft. The cylinder 102 has a hole and is provided with a pipe that is rotatably connected to the rotating shaft. One end of the pipe extends out of the hole on the cylinder 102 and is connected to the hose.
[0029] The output fixing seat 2 is located in front of the reel body 1, which is the direction in which the hose is pulled out. The hose interface is located above the limiting port 5. After the hose passes through the limiting port 5, it is wound on the cylinder 102. The diameter of the limiting port 5 is smaller than the diameter of the hose interface, which is used to block the hose interface.
[0030] The two ends of the lower support plate 202 are fixed to the two side plates 201, and the upper support plate 203 is movably connected to the two side plates 201. The sliding fit method used in this embodiment (not shown in the attached drawings) specifically refers to the upper support plate 203 slidingly engaging with the side plates 201, with a groove on the sliding plate allowing the upper support plate 203 to reciprocate up and down. In the free state, the height of the upper support plate 203 is higher than the height of the distance sensor 6. When the hose interface abuts against the limiting port 5, the upper support plate 203 is subjected to downward pressure and moves downwards. When the upper support plate 203 is directly opposite the distance sensor 6, the distance sensor 6 sends a signal to the controller, and the controller stops the drive motor 3. To ensure that the upper support plate 203 remains horizontal, multiple elastic elements 204 can be provided between the upper support plate 203 and the lower support plate 202.
[0031] The elastic element 204 can be a spring, and its two ends can be fixed between the upper support plate 203 and the lower support plate 202. To prevent the elastic element 204 from bending and deforming, a guide post 205 can also be provided between the upper support plate 203 and the lower support plate 202, such as... Figure 2 As shown, the lower end of the guide post 205 is fixed to the lower support plate 202, and the upper end passes through the mounting hole 7 of the upper support plate 203. The elastic element 204 is sleeved on the guide post 205.
[0032] In an optional embodiment, a number of rollers 8 are provided around the limiting port 5 to reduce friction between the hose and the edge of the limiting port 5.
[0033] The transmission assembly 4 may include, but is not limited to, a drive sprocket 401, a driven sprocket 402, and a chain 403. The drive sprocket 401 is connected to the drive motor 3, the driven sprocket 402 is connected to the center of the reel body 1, and the chain 403 connects the drive sprocket 401 and the driven sprocket 402. The rotation of the drive motor 3 drives the drive sprocket 401 to rotate, and the drive sprocket 401 drives the driven sprocket 402 to rotate. The reel body 1 and the driven sprocket 402 rotate synchronously.
[0034] Normally, the two ends of the reel body 1 are rotatably connected to the frame 10, and the side plates 201 are fixed to the frame 10. In a preferred embodiment, the frame 10 includes main panels 1001 located at both ends of the reel body 1, a rear connecting plate 1002 connecting the two main panels 1001 and located on the front and rear sides of the main panels 1001, and a front mounting plate 1003. The drive motor 3 is fixed to the front mounting plate 1003, and the side plates 201 are located above the front mounting plate 1003. Figure 1 and Figure 4 As shown, in this utility model, the direction in which the hose extends is the front and the opposite direction is the rear. The rear connecting plate 1002 and the front mounting plate 1003 are both located at the lower part of the main panel 1001, forming a stable frame with the two main panels 1001, so that the reel can be placed more stably on the ground. The main panel 1001 is connected to the reel body 1 through bearings.
[0035] Example 2
[0036] The difference between this embodiment and Embodiment 1 lies in the movement and installation method of the upper support plate 203. Specifically, in this embodiment, one end of the upper support plate 203 is hinged to the side plate 201 on the rotation shaft 9, and the other end of the upper support plate 203 is connected to the elastic element 204. When the hose interface presses against the upper support plate 203, the end of the upper support plate 203 connected to the elastic element 204 rotates around the rotation shaft 9, achieving a change in vertical position. This embodiment does not require the elastic element 204 to maintain the horizontal position of the upper support plate 203, therefore the number of elastic elements 204 is not too large. In addition, compared to the overall linear motion, the pressure required to generate rotational motion is lower, which helps to quickly receive the sensing signal.
[0037] The upper support plate 203 can be a simple plate structure. In this case, the upper support plate 203 needs to be designed to be relatively thick to block the contact of the distance sensor 6. However, this would increase the weight of the upper support plate 203 and affect the motion sensitivity. Therefore, the present invention preferably includes a flat plate 2031 and a baffle 2032 extending downward from the flat plate 2031. In this case, the thickness of the flat plate 2031 can be relatively thin, such as... Figure 5 As shown, in the free state, the baffle 2032 is positioned above the distance sensor 6; when the upper support plate 203 moves towards the lower support plate 202, the baffle 2032 is directly opposite the distance sensor 6, as shown. Figure 6 As shown.
[0038] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
