Description

Technical Field

[0001] The present invention relates to the field of passenger car water supply equipment, and particularly to a train water supply equipment with a redundant electric and mechanical rewinding structure for a new type of pipe outlet structure. Background Art

[0002] The main function of the train water supply equipment with a redundant electric and mechanical rewinding structure for a new type of pipe outlet structure is to convey water to the water tank or water cabinet of the train through a pipeline for the use of passengers and train staff. It not only provides drinking water for the train, but also guarantees the domestic water of the train, such as in the washroom, lavatory, etc.

[0003] At present, most of the existing train water supply equipment with a redundant electric and mechanical rewinding structure for a new type of pipe outlet structure uses a motor to drive a pipe reel to rotate for winding and unwinding the pipe. Generally, only one water outlet is provided at one end of the bolt body. However, in actual applications, one water supply bolt may be involved in the water supply operation for multiple water tanks. Therefore, after the pipeline is pulled out through the water outlet, it needs to be pulled in two different directions to the water supply position. When pulling the pipe on the side facing the water outlet, it is relatively convenient. However, when pulling in the opposite direction, the water supply pipe will bend and the pulling is very laborious.

[0004] Based on this, it is necessary to develop a train water supply equipment with a redundant electric and mechanical rewinding structure for a new type of pipe outlet structure to overcome the above technical problems. Summary of the Invention

[0030] Embodiment

[0031] As shown in Figure 1 , 2 , 3, 4, 5, 6, 7, 8, the novel train water supply device with redundant electric and mechanical rewinding of the pipe outlet structure in this embodiment includes a bolt body 2, a coiling disc 3, a mechanical rotary pipe coiler 4, and an electric rotary pipe coiler 7. A hollow central shaft 31 is coaxially provided at the center of the coiling disc 3, and the coiling disc 3 is rotationally assembled on a matching bracket inside the bolt body 2 through the central shaft 31. The mechanical rotary pipe coiler 4 and the electric rotary pipe coiler 7 are respectively installed in the bolt body 2, and one of them is in driving connection with one end of the central shaft 31. The other end of the central shaft 31 is rotatably provided with a water inlet joint 5 communicated with its inner cavity (using a matching type of rotary joint to connect to the municipal water pipe). A water supply pipe (not shown in the figure) is wound in the coiling disc 3. One end of the water supply pipe is connected and communicated with the central shaft 31 through a water outlet joint (designated as a in the figure). The other end of the water supply pipe is connected to a passenger car water inlet joint (not shown in the figure). A horizontally extending first notch 21 is provided at the top of the bolt body 2, and a vertically extending second notch 22 is provided on one side of the bolt body 2. The first notch 21 and the second notch 22 communicate at the upper part on one side of the bolt body 2, and the two together form a pipe outlet. A first cover plate 71 and a second cover plate 72 for opening or closing the two are respectively provided at the first notch 21 and the second notch 22. Among them, the bolt body 1 is a housing component, and the internal space is used to install various components.

[0032] The redundant electric and mechanical rewinding train water supply equipment with a novel pipe outlet structure in this embodiment is installed on the open space between two railway tracks in the station. The water inlet joint 5 is connected to the municipal water network through a pipeline, and a control valve is provided on the pipeline. When water supply is required during the train's stop, the operator opens the first cover plate 71 and the second cover plate 72, and holds the water supply joint of the passenger car to pull the pipeline out of the water supply joint of the passenger car from below the second notch 22 along the upper part of the tangent line of the reel 3 (that is, the water supply pipe is pulled out along the tangent line. More specifically, a section of the water supply pipe coming out of the reel 3 is pulled out obliquely upward from below the second notch 22 and forms a tangent or approximate tangent with the circumference of the reel 3, that is, a section of the water supply pipe pulled out of the reel 3 forms a tangent direction or approximate tangent direction with the circle formed by the remaining water supply pipe wound on the reel 3), which is relatively labor-saving. When water supply is required in another direction, the water supply joint of the passenger car is pulled out from the end of the first notch 21 far from the second notch 22, that is, the position near the other end of the top of the bolt body 2 (this pulling angle is also approximately the tangent direction of the upper part of the reel 3. More specifically, a section of the water supply pipe pulled out from the end of the first notch 21 forms a tangent direction or approximate tangent direction with the circle formed by the water supply pipe wound on the reel 3). Therefore, it is also relatively labor-saving to pull out from this position. The positions of the two pipe outlets exactly meet the operation of pulling out pipes in two opposite directions, and both are pulled out in the tangent or nearly tangent direction of the reel 3 (the reel 3 rotates and releases the pipe during the pulling process), and the operation is very labor-saving. The water supply pipe will not be bent when pulled in both directions. At the same time, in this embodiment, one of the two methods of mechanical rotary pipe winding or electric rotary pipe winding is adopted. Whether it is mechanical rotary or electric rotary, it is convenient to realize the pulling / rewinding operation in two directions, the operation is easy and labor-saving, and the customer has a variety of choices and can "adjust measures to local conditions" to select a more suitable pipe winding method. In addition, after the water supply is completed, the water supply pipe retracts and winds around the reel 3, the first cover plate 71 and the second cover plate 72 are covered, and the bolt body 2 returns to a sealed state, so that rainwater will not enter and damage the internal components on rainy days. Overall, the structural design is reasonable. Whether it is mechanical rotary or electric rotary, it is convenient to realize the pulling / rewinding operation in two directions, and the operation is easy and labor-saving; the bolt body has redundant mechanical pipe winding power and locking structure and electric pipe winding power mechanism installation interfaces, which is very convenient to realize the conversion between mechanical rotary and electric rotary pipe winding methods; when the equipment completes pipe winding, the water supply joint is automatically in a horizontal state, preventing the safety hazard of the equipment misoperating and spraying water upward; the equipment cover plate structure can play a good role in dust prevention, waterproof and heat preservation when the equipment is on standby.

[0033] In this embodiment, the water outlet joint is actually a block-shaped component with an inner cavity, which has a water inlet and a water outlet. The water inlet is connected and communicated with a through hole on the surface of the central shaft 31 (this through hole communicates with the inner cavity of the central shaft 31), and the water outlet is connected and communicated with the end of one end of the water supply pipe wound inside.

[0034] In this embodiment, the water inlet joint 5 can adopt a conventional rotary joint of a suitable model.

[0035] In this embodiment, the plug body 2 is a vertically arranged cuboid box. Its appearance is simple and beautiful.

[0036] Preferably, the plug body 2 includes two rectangular frames 211. The two frames 211 are arranged in parallel at intervals. Side plates are respectively encapsulated around the four sides of the two frames 211. Doors that can be opened or closed are respectively provided on the sides of the two frames 211 away from each other. The brackets are respectively provided in the frames 211. The two ends of the central shaft 31 are respectively rotationally assembled with the brackets (the two ends of the central shaft 31 are respectively coaxially and bearing-mounted on the corresponding brackets). The first notch 21 and the second notch 22 are respectively provided on the top side plate and one end side plate. The structural design of the plug body 2 is simple. The structure of welding the frame 211 and the side plates to each other is adopted, and the first notch 21 and the second notch 22 are opened on the side plates, and the structural design is reasonable.

[0037] In this embodiment, a first support roller 212 is rotationally installed at one end of the first notch 21 away from the second notch 22, and a second support roller 221 is rotationally installed at the lower end of the second notch 22. Among them, the height of the first support roller 212 is slightly higher than the height of the upper vertex of the outer edge of the reel 3, and the height of the second support roller 221 is slightly higher than the height of the lower vertex of the outer edge of the reel 3. When not in use, the water filling joint of the passenger car leans upward against the inner side of the second support roller 221. When the water filling joint of the passenger car is pulled out from the first support roller 212 or the second support roller 221 (the water supply pipe is pulled out along the surface of the first support roller 212 or the second support roller 221), and when pulled out, it is in a relative rolling fit relationship with the first support roller 212 or the second support roller 221, effectively reducing the friction when the water supply pipe is pulled out. Moreover, the water supply pipe is pulled out in a tangential or nearly tangential direction of the reel 3, which is relatively labor-saving, and this design is very ingenious.

[0038] As a preferred implementation manner, arc-shaped limiting edge strips 23 that semi-surround the periphery of the reel 3 are respectively provided on the sides of the two frames 211 close to each other. A gap for the water supply pipe to pass through is defined between the two limiting edge strips 23, and the width of the gap is smaller than the cross-sectional dimension of the water filling joint of the passenger car.

[0039] In the above embodiments, the water filling connector of the passenger car is generally designed as a cylindrical member, and the outer diameter of its cross-section is greater than the width of the limiting edge strip 23. Such a design makes the water filling connector of the passenger car always located outside the limiting edge strip 23 and will not retract into the inner side, facilitating pulling during subsequent use. At the same time, during standby, the water filling connector of the passenger car is "clamped" between the lower part of the second notch 22 and the limiting edge strip 23, maintaining the inclined upward posture of the water filling connector of the passenger car, which is beneficial for pulling and releasing the pipe next time. In addition, the water filling connector of the passenger car is at a position close to the ground during standby. Even if water leaks from the water filling connector of the passenger car due to pipeline failure, since the water filling connector of the passenger car is at a low position, the probability of it spraying onto the high-voltage grid above will be reduced.

[0040] In this embodiment, as Figure 8 shown, the above-mentioned coiling reel 3 includes two hollow circular reel frames 32, and the two above-mentioned reel frames 32 are arranged in parallel at intervals, and a central shaft 31 is fixedly passed through the centers of both of them. Among them, a single reel frame 32 includes an outer round rod and a plurality of connecting rods radially connected to the inner side of the round rod, and the ends of the connecting rods far from the round rod are respectively connected to the central shaft 31.

[0041] As a preferred embodiment, the above-mentioned mechanical rotary pipe coiler 4 includes a spring box 41, two first sprockets 42, a first chain and a one-way locking mechanism 43. The above-mentioned spring box 41 is arranged below one end of the above-mentioned central shaft 31, and a rotating shaft connected to the center of the spring inside it penetrates through the center of the spring box 41. The two above-mentioned first sprockets 42 are respectively assembled on one end of the above-mentioned central shaft 31 and the rotating shaft. The above-mentioned first chain surrounds the two above-mentioned first sprockets 42 and meshes with the above-mentioned first sprockets 42 respectively. The above-mentioned one-way locking mechanism 43 is connected to one end of the rotating shaft for locking the rotating shaft unidirectionally.

[0042] In the above embodiments, during the process of pulling out the water supply pipe outward, the coiling reel 3 is pulled and rotated. At the same time, since the central shaft 31 and the spring box 41 are connected by transmission through the first chain and the first sprockets 42, during the rotation of the central shaft 31 accordingly, the spring connected to it in the spring box 41 will undergo elastic deformation and store energy. At the same time, the one-way locking mechanism 43 always maintains one-way locking cooperation with the rotating shaft during the process of pulling out the water supply pipe. That is to say, when the pulling external force is withdrawn, the one-way locking mechanism 43 will immediately lock the rotating shaft to prevent it from rotating back. Since the spring in the spring box 41 is always in an energy storage state during the process of releasing the pipe, when it is necessary to retract the pipe after the water filling is completed, operate the one-way locking mechanism 43 to release the locking of the rotating shaft, and the spring in the spring box 41 will recover its deformation and drive the rotating shaft to rotate back. At the same time, it drives the central shaft 31 to rotate back through the first chain and the first sprockets 42, thereby driving the coiling reel 3 to rotate back, realizing the work of winding up the water supply pipe. This design is very ingenious and can achieve locking at any position after withdrawing the previous pulling force during the process of pulling out the water supply pipe outward, ensuring the smooth progress of the water filling work.

[0043] As a preferred embodiment, the above-mentioned one-way locking mechanism 43 includes a locking disk 431, a pawl 432 and an elastic member (not shown in the figure). The above-mentioned locking disk 431 is coaxially fixed to one end of the above-mentioned rotating shaft. The outer edge of the above-mentioned locking disk 431 is provided with a plurality of fan-shaped locking blocks 434 evenly distributed at intervals along the circumferential direction. The outer arc surface of the above-mentioned locking block 434 is provided with one-way inclined ratchet teeth. The above-mentioned pawl 432 is installed at the side end of the above-mentioned spring box 41 through a short shaft rotatably connected thereto. One end of the above-mentioned pawl 432 is provided with a tip that is unidirectionally engaged with the above-mentioned ratchet teeth. The other end of the above-mentioned pawl 432 is connected to the bottom of the above-mentioned bolt body 2 through an elastic member.

[0044] In the above-mentioned embodiment, during the process of pulling out the water supply pipe, the coiling disk 3 rotates, the central shaft 31 rotates synchronously, and the rotating shaft and the locking disk 431 will both rotate synchronously. The one-way inclined ratchet teeth on the locking block 434 will slide past the tip of the pawl 432. Once the central shaft 31 rotates back, then the tip of the pawl 432 will immediately be embedded into the groove between the adjacent ratchet teeth on the surface of the locking block 434, realizing one-way engagement, that is, preventing the central shaft 31 from rotating back (that is, preventing the coiling disk 3 from rotating back during the process of releasing the pipe), and the design is very ingenious.

[0045] In this embodiment, the above-mentioned elastic member is a spring. By using the elastic force of this elastic member, the tip of the pawl 432 is closely matched with the ratchet teeth on the outer edge of the locking block 434. Once the locking disk 431 rotates back, it can quickly respond to realize one-way engagement between the two. When coiling the pipe is needed, manually operate the pawl 432 to rotate and move by an angle so that its tip is away from the outer edge of the locking block 434, then the locking block 434 will no longer be restricted by one-way engagement, and under the action of the spring box 41, the action of rotating and winding the pipe (coiling the pipe) can occur. Of course, one end of the spring is connected to the pawl 432, and the other end can be connected to a bracket or other components (such as the spring box 41) inside the bolt body 2.

[0046] As a preferred embodiment, the above-mentioned electric rotary pipe coiler 7 includes a motor, two second sprockets and a second chain. The two above-mentioned second sprockets are respectively installed on the shaft of the above-mentioned motor and one end of the above-mentioned central shaft 31. The above-mentioned second chain surrounds the two above-mentioned second sprockets and meshes with the above-mentioned second sprockets respectively.

[0047] In the above-mentioned embodiment, by the forward and reverse rotation of the motor, the forward and reverse rotation of the second chain driving the second sprocket can be realized, so as to realize the forward and reverse rotation of the central shaft 31 driving the coiling disk 3, and realize the action of winding or releasing the pipe.

[0048] In this embodiment, a support frame is provided at the bottom of the above-mentioned bolt body 2, which is convenient for assembling and fixing with the base on the ground.
