Description

Technical Field

[0001] This invention relates to the field of waste bin structure technology, and more particularly to waste bin structure and tensile testing vehicle having the same. Background Technology

[0002] In the railway transportation industry, ensuring train operation safety and passenger travel experience is of paramount importance. Vehicle performance indicators must undergo rigorous testing to ensure safe and stable operation under various conditions. As a special-purpose train, the tensile testing vehicle plays a crucial role in testing key performance parameters such as traction and braking force. Optimizing its structure and functions is of great significance for ensuring railway transportation safety.

[0003] To test the traction and braking forces of a vehicle, a tensile testing vehicle has a tensile gauge module installed along the length of the vehicle body at one end of the bottom. As a core testing component, the tensile gauge module requires regular maintenance and inspection; therefore, an openable inspection door is installed at its bottom. Simultaneously, to ensure the hygiene of the personnel on board, the tensile testing vehicle must be equipped with a waste collection tank. Considering the convenience of performing vacuuming and rinsing operations from both sides of the vehicle body, the waste collection tank is usually positioned along the width of the vehicle body, allowing for vacuuming and rinsing ports on both sides. Due to limited space at the bottom of the vehicle body, and to avoid interference with the tensile gauge module, the waste collection tank is generally located below the tensile gauge module.

[0004] Placing the waste bin below the tension gauge module occupies space beneath it. When the inspection door at the bottom of the tension gauge module needs to be opened, the waste bin obstructs the door, making maintenance difficult and increasing maintenance complexity. If the waste bin size is reduced to accommodate the space below the tension gauge module, the bin's capacity will be too small, resulting in insufficient waste storage and failing to meet the hygiene needs of passengers, thus reducing passenger comfort.

[0005] In summary, the existing waste bin design of tensile testing vehicles has many problems in terms of space utilization and maintenance convenience. There is an urgent need to develop an optimized waste bin structure to solve the above-mentioned technical problems and improve the overall performance and user experience of tensile testing vehicles. Summary of the Invention

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a waste bin structure, including a bin body, a near-end operation port group, a far-end operation port group, and a connecting pipe group. The bin body is suspended from the bottom of the vehicle body and is arranged along the length of the vehicle body. The near-end operation port group is located on the bin body, and the far-end operation port group is suspended from the bottom of the vehicle body and connected to the bin body through the connecting pipe group. The bin body and the far-end operation port group are respectively arranged on both sides of the width direction of the tensile test module. The connecting pipe group is located on the rear side of the tensile test module to avoid the inspection door at the bottom of the tensile test module.

[0007] In one possible implementation, the near-end operating port group includes a near-end suction port, a near-end flushing port, and a near-end air intake port that are connected to the housing, and the far-end operating port group includes a far-end suction port, a far-end flushing port, and a far-end air intake port that are connected to the housing via the connecting pipe group.

[0008] In one possible implementation, the connecting pipe assembly includes a suction pipe, a flushing pipe, and an air inlet pipe, wherein the suction pipe, the flushing pipe, and the air inlet pipe are all two-sectioned. The two suction pipes are spaced apart along their own axial direction and their adjacent inner ends are connected by a suction hose. The outer ends of the two suction pipes that are opposite to each other are respectively connected to the box and the far-end suction port. The two flushing pipes are spaced apart along their own axial direction, with a flushing hose connected between the two ends on the inner side and the two ends on the outer side connected to the box body and the remote flushing port, respectively. The two intake pipes are spaced apart along their own axial direction, with an intake hose connecting the two ends on the inner side and the two ends on the outer side respectively connected to the housing and the far-end intake port.

[0009] In one possible implementation, the inner end of the suction pipe is provided with a reduced diameter section, the reduced diameter section has a reduced diameter opening, and a plug is slidably disposed in the reduced diameter section along the axial direction, the plug being able to abut against and seal the reduced diameter opening after sliding.

[0010] In one possible implementation, the suction hose is provided with connecting rings at both ends, and the connecting rings at both ends are respectively used to seal and insert into the openings of the two reduced diameter sections.

[0011] In one possible implementation, a spring is connected between the inner wall of the reduced diameter section and the plug, the spring being used to provide a force for the plug to approach and seal the reduced diameter opening, and a push rod is provided inside the connecting ring; When the connecting ring is axially inserted into the reduced diameter section of the pipe, the push rod can push the plug to open the reduced diameter section. When the connecting ring axially disengages from the reduced diameter section of the pipe, the push rod can move away from the plug, so that the plug abuts against and seals the reduced diameter section under the elastic force of the spring.

[0012] In one possible implementation, the reduced diameter section is detachably connected to the inner end of the suction pipe to facilitate the installation of the plug and the spring. The inner wall of the reduced diameter section is provided with a reduced diameter ring, the center of which forms the reduced diameter opening. The edge of the plug facing the reduced diameter opening has a chamfer, which is used to contact the edge of the reduced diameter opening.

[0013] In one possible implementation, the connecting pipe assembly is fitted with an outer protective tube, which is used to protect the suction pipe, the flushing pipe and the air inlet pipe.

[0014] In one possible implementation, the top of the housing is provided with a hook for connecting to the bottom of the vehicle body, and both the remote operation port group and the connecting pipe group are connected to brackets for connecting to the bottom of the vehicle body.

[0015] According to another aspect, at least one embodiment of the present invention also provides a tensile testing vehicle, including the aforementioned waste bin structure.

[0016] Compared with the prior art, the waste bin structure provided in this embodiment of the invention has the following significant technical advantages: By changing the layout of the box and placing it on one side of the width direction of the tensile gauge module at the same height as the tensile gauge module, excessive occupation of the space below the tensile gauge module is avoided, the spatial conflict between the waste bin and the tensile gauge module is resolved, and the inspection door at the bottom of the tensile gauge module can be easily opened, reducing the difficulty of maintenance.

[0017] The combination of near-end and far-end operating port groups with connecting pipe groups enables convenient operations such as vacuuming and rinsing to be performed from both sides of the train body. Regardless of which side the waste is handled from when the train is stopped, staff can easily connect the equipment to operate it, improving the efficiency of waste handling and meeting the operational needs of actual operation.

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, components with the same structure or function are shown only schematically, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] It should be noted that when an element is referred to as being "set on" another element, it can be directly set on the other element or indirectly set on the other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0027] A tensile testing vehicle is a specialized train used for testing vehicle traction and braking forces. To achieve this testing, a tensile gauge module 7 is installed along the length of the vehicle body at one end of the bottom. As a core testing component, the tensile gauge module 7 requires regular maintenance and repair; therefore, an openable and closable inspection door 8 is provided at its bottom. The arrangement of the tensile gauge module 7 in existing technology is as follows: Figure 7 .

[0028] Waste bins are essential equipment for ensuring the hygiene and sanitation of passengers on board. The waste bins have a box-like structure and are located at the end of the vehicle body. Traditional waste bin placement is as follows: Figure 8 As shown.

[0029] In the tensile testing vehicle, to avoid interference, the waste bin installed on the vehicle is a single-piece structure, which needs to be arranged below the tensile gauge module 7 via a connecting structure at the bottom of the vehicle body, such as... Figure 9 As shown.

[0030] The waste bin is placed below the tension gauge module 7, which occupies the space below the tension gauge module 7. When it is necessary to open the inspection door 8 at the bottom of the tension gauge module 7, the waste bin will obstruct the opening of the inspection door 8, making it difficult for staff to open the inspection door 8 for maintenance operations and increasing the difficulty of maintenance.

[0031] If the size of the waste bin is reduced to meet the space requirements below the tension gauge module 7, the waste bin capacity will be too small, resulting in insufficient waste storage capacity. This will fail to meet the hygiene needs of the passengers and reduce their comfort.

[0032] To resolve the above technical issues, please refer to Figures 1-6 The illustration shows a waste bin structure in one embodiment of the present invention, including a bin body 1, a near-end operation port group 2, a far-end operation port group 3, and a connecting pipe group 4. The top of the bin body 1 is provided with a hook 5 for connecting to the bottom of the vehicle body, and the far-end operation port group 3 and the connecting pipe group 4 are both connected to a bracket 6 for connecting to the bottom of the vehicle body.

[0033] When installing the waste bin structure, first connect the hook 5 on the top of the bin 1 to the corresponding connection point on the bottom of the vehicle body. Arrange it along the length of the vehicle body on one side of the width of the tension gauge module 7. The bin 1 and the tension gauge module 7 are at the same height. This changes the traditional layout where the waste bin is located below the tension gauge module 7, avoids occupying the space below the tension gauge module 7, and allows the inspection door 8 at the bottom of the tension gauge module 7 to be opened normally without obstruction, making it convenient for staff to carry out maintenance and repair.

[0034] Because the housing 1 is offset to one side of the vehicle's central axis, it is impossible to directly perform operations such as vacuuming and rinsing on the other side of the vehicle. To meet the convenience requirement of being able to perform related operations on both sides of the vehicle, a near-end operation port group 2 is directly installed on the housing 1 on the side of the vehicle closer to the housing 1; on the other side of the vehicle away from the housing 1, a far-end operation port group 3 is connected to the housing 1 via a connecting pipe group 4 with a bracket 6. The bracket 6 is used to suspend the far-end operation port group 3 at the bottom of the vehicle and is located on the opposite side of the width direction of the tension gauge module 7.

[0035] When operations such as vacuuming or rinsing the waste bin are required, the operation can be performed directly through the near-end operating port group 2 on the side of the vehicle body closest to the bin 1. On the other side of the vehicle body away from the bin 1, the far-end operating port group 3 is connected to the bin 1 via a connecting pipe group 4. On this side, the operator can connect the corresponding rinsing or vacuuming equipment through the far-end operating port group 3, which is then transmitted to the bin 1 via the connecting pipe group 4 to perform rinsing or vacuuming operations inside the bin 1. This solves the space problem and ensures that operating ports are available on both sides of the vehicle body, enabling vacuuming and rinsing operations to be performed from both sides of the vehicle body.

[0036] By changing the layout of the housing 1 and placing it on one side of the width direction of the tension gauge module 7 and at the same height as the tension gauge module 7, excessive occupation of the space below the tension gauge module 7 is avoided, the spatial conflict between the waste bin and the tension gauge module 7 is resolved, and the inspection door 8 at the bottom of the tension gauge module 7 can be opened easily, reducing the difficulty of maintenance.

[0037] The combination of near-end operation port group 2 and far-end operation port group 3 with the connecting pipe group 4 enables convenient operations such as vacuuming and rinsing to be performed from both sides of the train body. Regardless of which side the waste is handled from when the train is stopped, staff can easily connect the equipment to operate it, improving the efficiency of waste handling and meeting the operational needs in actual operation.

[0038] As a specific embodiment, the near-end operation port group 2 is provided with a near-end suction port 201, a near-end flushing port 202, and a near-end air inlet port 203. The near-end suction port 201 is used to connect to a suction device to suck out the dirt from the tank 1, and the near-end flushing port 202 is used to connect to a flushing device to spray high-pressure water into the tank 1. In the prior art, a negative pressure generating unit is installed in the tank 1 to facilitate the collection of dirt. However, before performing suction and flushing operations, it is necessary to restore normal pressure. Therefore, air is injected through the near-end air inlet port 203 to first bring the tank 1 to a normal pressure state to facilitate subsequent operations. The far-end operation port group 3 includes a far-end suction port 301, a far-end flushing port 302, and a far-end air inlet port 303, and its function is the same as that of the near-end operation port group 2.

[0039] Regarding the operation procedure for vacuuming, taking the treatment of waste on the side of the vehicle body near the box 1 as an example, firstly, connect the air intake device to the near-end air intake port 203 to inject air into the box 1, so that the pressure inside the box 1 returns to normal pressure; then connect the vacuuming device to the near-end vacuuming port 201, start the vacuuming device, and use suction to suck the waste inside the box 1 into the collection device to complete the vacuuming operation; after the vacuuming is completed, connect the flushing device to the near-end flushing port 202, start the flushing device, and high-pressure water jets are sprayed into the box 1 through the flushing port to flush the inside of the box 1, remove residual waste, and ensure that the inside of the box 1 is clean.

[0040] By setting up operation port groups with functions of sewage suction, flushing and air intake on both sides of the vehicle body, the convenience of sewage treatment operation is improved. Operators can flexibly choose to operate from either side of the vehicle body according to the actual situation, thereby improving work efficiency.

[0041] As a specific embodiment, the connecting pipe assembly 4 consists of a suction pipe 401, a flushing pipe 402, and an air inlet pipe 403. Each pipe is designed with two sections, which are connected by a suction hose 404, a flushing hose 405, and an air inlet hose 406, respectively. Under normal operating conditions, during suction, the suction device removes waste from the housing 1 through the remote suction port 301 and the suction pipe 401. The suction hose 404 connects the two sections of the suction pipe 401 to ensure smooth suction. During flushing, the flushing device delivers high-pressure water to the housing 1 through the remote flushing port 302 and the flushing pipe 402. The flushing hose 405 connects the two sections of the flushing pipe 402 to ensure stable water flow. During air intake, the air intake device injects air into the housing 1 through the remote air intake port 303 and the air intake pipe 403. The air intake hose 406 connects the two sections of the air intake pipe 403 to ensure the air intake channel is open.

[0042] When disassembling the container 1, the operator only needs to disconnect the three sections of hose to break the connection between the container 1 and the remote operation port assembly 3. Then, disconnect the top hook 5 of the container 1 from the bottom of the vehicle body, allowing the container 1 to be directly removed from its side along the width of the vehicle body. Similarly, for the remote operation port assembly 3, after disconnecting its bracket 6 from the bottom of the vehicle body, it can also be directly removed from its side along the width of the vehicle body. This achieves the separate disassembly of the waste container structure, avoiding the problem of difficulty in operation caused by collisions with surrounding components due to the limited space at the bottom of the vehicle body during overall disassembly.

[0043] Considering that the connecting pipe assembly 4 may be affected by external factors during train operation, such as impact from foreign objects and vibration wear, an outer protective pipe 413 is installed around the connecting pipe assembly 4 to protect the suction pipe 401, flushing pipe 402, and air inlet pipe 403. The outer protective pipe 413 can block impacts from foreign objects and reduce the risk of damage to the connecting pipe assembly 4. The outer protective pipe 413 also adopts a two-section design, connecting to the housing 1 and the remote operation port assembly 3 respectively. This ensures that it can fully cover the connecting pipe assembly 4 to provide protection, and is also compatible with the split structure of the connecting pipe assembly 4. When disassembling the housing 1 and the remote operation port assembly 3, the outer protective pipe 413 can also be separated without affecting the disassembly operation.

[0044] In a specific embodiment, a reduced-diameter section 407 is provided at the inner end of the suction pipe 401. The diameter of the reduced-diameter section 407 is smaller than the diameter of the main body of the suction pipe 401, thereby forming a reduced-diameter opening 408 inside. A plug 409 is slidably disposed along the axial direction of the reduced-diameter section 407, and the plug 409 can seal the reduced-diameter opening 408. Connecting rings 410 are provided at both ends of the suction hose 404 for sealing and inserting with the opening of the reduced-diameter section 407. The connecting ring 410 has a built-in push rod 412, and the inner wall of the connecting ring 410 is provided with support rods along its own radial direction. Multiple support rods are arranged at intervals along the circumference of the connecting ring 410. In this embodiment, three rods are preferred. The push rod 412 is located in the axial direction of the connecting ring 410 and is connected to the end of the multiple support rods. The push rod 412 is used to press against the plug 409. Spring 411 is connected between the inner wall of the reduced diameter section 407 and the plug 409. Its function is to provide a force to bring the plug 409 close to the reduced diameter opening 408, so as to ensure that the plug 409 can seal the reduced diameter opening 408 when no external force is applied.

[0045] When installing the suction hose 404, axially insert the connecting ring 410 into the opening of the reduced-diameter section 407 (the connection between the connecting ring 410 and the reduced-diameter section 407 can also be a threaded connection). As the connecting ring 410 is inserted, the push rod 412 inside the connecting ring 410 contacts the plug 409. Due to the pushing force of the push rod 412, the plug 409 overcomes the elastic force of the spring 411 and slides away from the reduced-diameter opening 408, thus opening the reduced-diameter opening 408. After the connecting ring 410 is fully inserted, the push rod 412 continues to press against the plug 409, keeping the reduced-diameter opening 408 open, so that the two sections of the suction pipe 401 are connected through the suction hose 404, thereby ensuring the smooth progress of the suction process. Conventional sealing measures are set between the connecting ring 410 and the opening of the reduced-diameter section 407 to ensure that sewage does not leak from the connection during the suction process.

[0046] When the suction hose 404 needs to be disassembled, the operator pulls the connecting ring 410 axially. During the pulling process, the push rod 412 disengages from the plug 409, and the plug 409 slides towards the reduced diameter port 408 under the elastic force of the spring 411 until it abuts against and seals the reduced diameter port 408. Before the connecting ring 410 is completely pulled out of the reduced diameter section 407, the plug 409 has already sealed the reduced diameter port 408. In this way, when the connecting ring 410 is completely pulled out, the reduced diameter section 407 is already sealed, preventing leakage of residual sewage in the suction pipe 401 after the suction hose 404 is pulled out, and also preventing the spread of odors.

[0047] To facilitate the installation of the plug 409 and spring 411, the reduced diameter section 407 is designed to be detachably connected to the inner end of the suction pipe 401. This allows the plug 409 and spring 411 to be installed inside the reduced diameter section 407 before connecting it to the end of the suction pipe 401, simplifying the installation process and improving assembly efficiency.

[0048] On the other hand, the present invention also provides a tensile testing vehicle, including the aforementioned waste bin structure.

[0049] A tensile gauge module 7 is installed at one end of the bottom of the tensile test vehicle along the length of the vehicle body. The tensile gauge module 7 is the core component for testing the vehicle's traction and braking force. In order to avoid interference with the tensile gauge module 7 and to meet the requirements of vacuuming and rinsing operations on both sides of the vehicle body, this solution improves the layout structure of the waste tank.

[0050] The waste bin is suspended at the bottom of the vehicle body, along the length of the vehicle body, and located on one side of the width of the tensile gauge module 7, at the same height as the tensile gauge module 7. This solves the problem that the waste bin occupies the space below the tensile gauge module 7 in the traditional setting, which causes the inspection door 8 to be obstructed from opening.

[0051] On the side of the vehicle body closest to the container 1, a near-end operation port group 2 is provided on the container 1, including a near-end suction port 201, a near-end flushing port 202, and a near-end air intake port 203, facilitating the operation of suctioning, flushing, and air intake of the waste container by personnel on this side. On the other side of the vehicle body away from the container 1, a far-end operation port group 3 is connected to the container 1 via a connecting pipe group 4. The far-end operation port group 3 also includes a far-end suction port 301, a far-end flushing port 302, and a far-end air intake port 303, and its functions correspond to those of the near-end operation port group 2.

[0052] By rationally arranging the waste bin structure, the tensile testing vehicle solves the problems of unreasonable space utilization and inconvenient maintenance caused by traditional waste bin settings. This optimizes the use of space under the vehicle body, improves the overall layout rationality, and enhances the ease of maintenance for the tensile gauge module 7. Operating ports are located on both sides, allowing staff to easily handle waste from either side, improving work efficiency. The reduced diameter section 407 at the end of the suction pipe 401 prevents sewage leakage and odor diffusion, improving the working environment.
