Through passage folding canopy; Detailed Implementation It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Example 1 like Figure 1 , Figure 2 , Figure 3 As shown in the figure, this embodiment proposes a cleaning device for a through-passage folding canopy 4, including: a supporting component 1, a lifting component 3, and a spraying component 2; the supporting component 1 includes a frame structure 12, the frame structure 12 has a receiving cavity in the middle, and the through-passage folding canopy 4 is placed in the receiving cavity; the lifting component 3 is installed on the top of the frame structure 12, and is used to lift the top of the through-passage folding canopy 4 and thus unfold the through-passage folding canopy 4; the spraying component 2 includes a spray box 21, a spray pipe, and a spray head 24, the spray box 21 is arranged in the middle of the frame structure 12 and is located in the middle of the through-passage folding canopy 4, the spray pipe is rotatably installed on the spray box 21, and the spray pipe is installed at the end of the spray pipe.

[0021] The frame structure 12 of the supporting component 1 has a cavity in the middle, providing a dedicated space for the folding canopy 4 in the passageway. This ensures that the cleaning operation is carried out within a fixed area, solving the problem of the folding canopy easily tipping over when there is no fixed placement position during traditional manual cleaning. The lifting component 3 is installed on top of the frame structure 12 and can directly act on the top of the folding canopy 4 in the passageway. By lifting, the folding canopy is unfolded, allowing the gaps, folds, and corners of the folding canopy to be fully exposed, creating conditions for subsequent comprehensive cleaning and solving the technical problem of incomplete cleaning in traditional cleaning methods.

[0022] In the spray assembly 2, the spray box 21 is located in the middle of the frame structure 12 and in the middle of the through-passage folding canopy 4. The spray pipe is rotatably mounted on the spray box 21, and the spray head 24 is mounted on the end of the spray pipe. This structure allows the spray pipe to rotate around the spray box 21, driving the spray head 24 to adjust the spray angle, which can cover the entire circumference of the folding canopy. The load-bearing assembly 1, the lifting assembly 3, and the spray assembly 2 work together to form a fixed-unfolding-comprehensive spraying cleaning process, reducing manual intervention and labor consumption.

[0023] In addition to being directly connected to the spray box 21, the spray pipe can also be rotated by a bearing structure. The bearing is installed between the spray box 21 and the spray pipe, which can reduce the friction when the spray pipe rotates and make the rotation smoother. In addition to the end of the spray pipe, the number of spray heads 24 can also be appropriately increased in the middle of the spray pipe to further improve the spray coverage density.

[0024] The frame structure 12 includes a bottom frame and side frames, with the side frames located on opposite sides of the bottom frame, forming a U-shaped structure. The bottom frame provides bottom support for the entire frame structure 12, enhancing its stability and ensuring structural stability when the load-bearing component 1 is placed on the folding canopy or when the lifting component 3 lifts the folding canopy. This prevents the folding canopy from falling or being damaged due to frame instability, thus improving the safety of the device. The U-shaped side frames provide an installation foundation for the subsequent installation of the lifting beam 14 on the frame structure 12. The presence of the side frames ensures stable connection points at both ends of the lifting beam 14, guaranteeing that the lifting component 3 can stably lift the folding canopy after installation.

[0025] The bottom frame and side frames can be made of high-strength metal materials, such as steel, to ensure the load-bearing capacity of the frame structure 12 and avoid frame deformation due to the weight of the folding canopy; the height of the side frames can be designed according to the unfolded height of the through passage folding canopy 4.

[0026] In addition to fixed welding, the side frame and the bottom frame can also be connected by bolts. Bolt connection makes it easy to disassemble and replace the side frame. When the side frame is damaged, it is not necessary to replace the entire frame structure 12, only the side frame needs to be replaced, which reduces maintenance costs. In addition to rectangle, the bottom frame can also be designed as square, as long as it can meet the requirements of bearing the folding canopy and installing the side frame. The specific shape can be adjusted according to the space size of the actual use scenario.

[0027] like Figure 2 , Figure 3 As shown, a lifting beam 14 is provided on the frame structure 12, and the lifting assembly 3 is installed on the lifting beam 14. The lifting beam 14 has two beams, and the two ends of the lifting beam 14 are respectively connected to the side beams on both sides.

[0028] A lifting beam 14 is provided on the frame structure 12, and the lifting assembly 3 is installed on the lifting beam 14. The lifting beam 14 provides a stable installation carrier for the lifting assembly 3. Compared with directly installing the lifting assembly 3 on the top of the side frame, the structure of the lifting beam 14 is more stable and can disperse the tension generated when the lifting assembly 3 lifts the folding canopy, avoid the side frame from deforming due to excessive local stress, and extend the service life of the frame structure 12.

[0029] The lifting beam 14 has two side beams connected to both ends of the beams on both sides. The two lifting beams 14 are symmetrically distributed, so that the lifting assembly 3 can be installed on the two lifting beams 14 respectively. It can be lifted from different positions of the folding tent, ensuring that the force is even when the folding tent is lifted. This avoids the situation where the folding tent tilts or cannot be unfolded due to lifting from a single point or near a single point, improves the flatness of the unfolded folding tent, and further provides a guarantee for comprehensive cleaning.

[0030] The design of two lifting beams 14 can accommodate multiple lifting components 3. Multiple lifting components 3 are installed on the two lifting beams 14 respectively, which can distribute the weight of the folding shed more evenly, making the lifting process more stable. At the same time, it can also avoid failure caused by excessive load on a single lifting component 3, thus improving the safety and reliability of the lifting operation.

[0031] The lifting beam 14 is also made of high-strength metal material, consistent with the bottom frame and side frame materials, ensuring the uniform strength of the overall frame structure 12. The connection between the lifting beam 14 and the side beam can be welded or bolted. Bolted connection facilitates the adjustment of the position of the lifting beam 14, and the installation position of the lifting beam 14 on the side beam can be adjusted according to the lifting requirements of different sized folding canopies.

[0032] The frame structure 12 is also provided with a support frame 13, which is installed in the middle of the bottom frame, and the spray box 21 is installed on the support frame 13.

[0033] The support frame 13 provides an independent installation support structure for the spray box 21. Compared with placing the spray box 21 directly on the bottom frame, the support frame 13 can fix the spray box 21 at a specific height, ensuring that the spray box 21 is located in the preset position in the middle of the through passage folding canopy 4.

[0034] The support frame 13 fixes the position of the spray box 21, ensuring that the spray pipe can rotate around the fixed spray box 21 when it rotates, and preventing the spray box 21 from moving and causing the spray pipe to deviate from the folding canopy; at the same time, the presence of the support frame 13 will not affect the placement of the folding canopy in the housing cavity of the bearing component 1.

[0035] The support frame 13 can be made by welding metal rods to form a frame structure, which ensures the support strength and reduces the weight. The height of the support frame 13 can be designed according to the height of the spray box 21 and the thickness of the through channel folding canopy 4.

[0036] The supporting component 1 is also equipped with a traveling wheel 11, which is installed at the bottom of the frame structure 12, enabling the entire device to move. Compared with the traditional fixed-position cleaning method, the operator can push the device to the storage position of the through-channel folding shed 4, eliminating the need for manual handling of the folding shed to the fixed cleaning point, reducing manpower consumption and damage risk during the handling of the folding shed, and solving the problem of high manpower consumption in the traditional cleaning method.

[0037] The wheels 11 can be made of rubber, which provides cushioning and reduces impact with the ground during movement, while increasing friction to prevent slippage. Four wheels 11 can be installed at the four corners of the bottom frame of the frame structure 12 to ensure even and stable force distribution during movement.

[0038] The lifting assembly 3 has four components (only one is shown in the figure for clarity), including an electric hoist 31, a sling 32, and a hook 33. The electric hoist 31 is mounted on the lifting beam 14, the upper end of the sling 32 is mounted on the electric hoist 31, and the hook 33 is mounted on the lower end of the sling 32. A lifting ring is installed on the through-channel folding canopy 4, and the hook 33 is hooked onto the lifting ring. The four lifting assemblies 3 are respectively hooked onto the four lifting rings.

[0039] The upper end of the sling 32 is installed on the electric hoist 31, and the lower end is installed with a hook 33. The hook 33 is hooked on the lifting ring of the folding tent. The four lifting components 3 are hooked on the four lifting rings respectively. The setting of four lifting points makes the force more even when the folding tent is lifted, and the folding tent can be lifted synchronously from four directions. This avoids the situation where the folding tent tilts or the folds cannot be unfolded due to single-point or two-point lifting. It ensures that the folding tent can be fully unfolded, so that all surfaces of the folding tent are fully exposed, which provides a guarantee for the comprehensive cleaning of the spray component 2 and solves the problem of incomplete cleaning by traditional cleaning methods.

[0040] The electric hoist 31 can be a model with a power-off braking function, which can brake in time in the event of a sudden power failure to prevent the folding canopy from falling due to the descent of the lifting strap 32. The lifting strap 32 is made of high-strength synthetic fiber material, which is wear-resistant and has a strong load-bearing capacity. Its length can be designed according to the unfolded height of the folding canopy to ensure that the folding canopy can be lifted to a suitable height. The shape of the hook 33 must be compatible with the lifting ring on the folding canopy to ensure a secure attachment and prevent it from falling off during lifting.

[0041] The spray pipe includes an outer spray pipe 23, which consists of an inner pipe, a top pipe, and an outer pipe connected in sequence. The inner pipe is rotatably mounted on the spray box 21, allowing the outer spray pipe 23 to rotate around the spray box 21, thereby adjusting the spray direction of the spray heads 24 on the outer pipe. The top pipe is higher than the hanging beam 14, and the outer pipe is located outside the frame structure 12. Spray heads 24 facing inward are installed at the bottom of the outer pipe, which can cover the outer surface of the folding canopy. Combined with the effect of the lifting assembly 3 unfolding the folding canopy, it achieves comprehensive cleaning of the outer side of the folding canopy, improving the thoroughness of the cleaning.

[0042] In another embodiment, a flexible hose can be added between the spray head 24 and the spray pipe. The hose is flexible and the angle of the spray head 24 can be manually adjusted, so that the spray can be more accurately aimed at the folds, corners and other parts of the folding shed that are prone to dirt residue. This makes up for the limited rotation angle of the outer spray pipe 23 and improves the cleaning effect.

[0043] The inner, top, and outer pipes of the external spray pipe 23 can be made of stainless steel. Stainless steel is corrosion-resistant, which can prevent the pipe from rusting due to long-term contact with cleaning agents and extend its service life. The spray head 24 is designed with a columnar spray pattern, which is suitable for stubborn dirt and has a stronger impact force.

[0044] The spray pipe also includes an inner spray pipe 22, one end of which is connected to the inner pipe of the outer spray pipe 23. The other end of the inner spray pipe 22 is fitted with an outward-facing spray head 24 via a ball joint, and the rotation range of the inner spray pipe 22 is located inside the through-channel folding shed 4. The inner spray pipe 22 and the outer spray pipe 23 share the inner pipe and the cleaning agent supply of the spray box 21, eliminating the need for additional cleaning agent delivery pipelines, simplifying the structure and reducing equipment costs.

[0045] The inner spray pipe 22 is located inside the folding shed, and the spray head 24 sprays outwards, which can clean the inner surface of the folding shed. Combined with the effect of the outer spray pipe 23 spraying from the outside, the inner and outer surfaces of the folding shed can be cleaned at the same time. Compared with the traditional method of cleaning the outside first and then the inside, it shortens the cleaning time, improves the cleaning efficiency, and solves the problem of low efficiency of traditional cleaning methods.

[0046] The spray pattern of the spray head 24 of the inner spray pipe 22 is designed as a mist spray, which is suitable for light dirt on the surface of the folding shed and can evenly cover the surface.

[0047] The spray assembly 2 also includes a liquid storage tank and a spray pump (not shown in the figure). The liquid storage tank is used to store cleaning agent. The spray pump is connected to the liquid storage tank and the spray tank 21 through a liquid delivery pipeline. The spray pump can pressurize the cleaning agent, so that the cleaning agent is sprayed onto the surface of the folded tent through the spray pipe and the spray head 24 at a certain pressure. The pressurized cleaning agent can penetrate into the folds, gaps, corners and other parts of the folded tent more fully, and fully contact and react with the dirt, thereby improving the dirt removal effect and solving the problem of incomplete cleaning by traditional cleaning methods.

[0048] The storage tank is made of corrosion-resistant materials such as polyethylene or stainless steel, which prevents corrosion of the tank due to long-term storage of the cleaning agent and extends its service life. A liquid level observation window can be installed on the storage tank, allowing operators to easily check the remaining cleaning agent level in real time and replenish it promptly. A centrifugal pump can be used for the spray pump, which features stable flow rate and convenient pressure adjustment; its operating parameters can be adjusted according to the degree of soiling on the fins. The infusion pipeline uses pressure-resistant rubber or plastic tubing to ensure that it will not rupture or leak after the spray pump is pressurized.

[0049] In summary, using this cleaning device to clean the through passageway folding canopy 4 has the following advantages: Significant savings in manpower and resources: Lifting component 3 enables mechanized hoisting of the folding canopy 4 in the passageway, replacing the traditional manual lifting method and greatly reducing manpower input. Simultaneously, due to the high degree of automation, only a small number of operators are needed for monitoring and operation, further reducing labor costs. Furthermore, the efficient operation of the equipment reduces reliance on other auxiliary tools and equipment, saving material resources.

[0050] Significantly improved cleaning results: The lifting assembly 3 fully unfolds the folding tent, eliminating blind spots and ensuring effective cleaning of every part of the tent. The spray assembly 2 evenly sprays the cleaning agent onto the surface of the folding tent, ensuring full contact between the cleaning agent and the dirt. Combined with a proper cleaning process, it can thoroughly remove various types of dirt from the folding tent, achieving a cleaning effect far superior to traditional manual cleaning methods.

[0051] The cleaning efficiency is greatly improved: the automated support hoisting and spray cleaning process significantly shortens the cleaning time. Compared with traditional manual cleaning, this device can complete the cleaning of the through passage folding canopy 4 in a shorter time, improving cleaning efficiency, helping to shorten the train maintenance cycle, ensuring that trains can be put into operation on time, and improving the operational efficiency of the entire railway transportation system.

[0052] Example 2 This embodiment proposes a cleaning method for the through-passage folding canopy 4 cleaning device as described in Embodiment 1, comprising the following steps: placing the through-passage folding canopy 4 on the support component 1; lifting the through-passage folding canopy 4 and unfolding it using the lifting component 3; simultaneously spraying cleaning agent onto the inner and outer surfaces of the unfolded through-passage folding canopy 4 using the spraying component 2; controlling the spraying pressure, spraying angle, and spraying time of the spraying component 2 to cover the entire surface of the folding canopy; and after spraying is completed, lowering the through-passage folding canopy 4 and removing it from the support component 1 using the lifting component 3.

[0053] The folding canopy 4 is placed on the bearing component 1. The accommodating cavity of the bearing component 1 provides a fixed placement space for the folding canopy, preventing it from shifting during subsequent lifting and ensuring the accuracy of the lifting operation. Compared with the traditional method of manually placing the folding canopy randomly, this reduces lifting delays caused by improper placement and improves process efficiency.

[0054] The folding canopy 4 of the passageway is lifted and unfolded by the lifting assembly 3. The four lifting points of the lifting assembly 3 are evenly stressed to ensure that the folding canopy is fully unfolded, so that the folds, gaps and corners of the folding canopy are fully exposed, creating conditions for the subsequent spraying assembly 2 to spray the cleaning agent. This solves the problem of blind spots in cleaning caused by the inability to unfold the folding canopy by hand in the traditional way, and improves the thoroughness of cleaning.

[0055] The spray assembly 2 sprays cleaning agent simultaneously onto the inner and outer surfaces of the unfolded through-channel folding shed 4. The inner spray pipe 22 and the outer spray pipe 23 of the spray assembly 2 spray from the inner and outer sides of the folding shed, respectively. Combined with the pressurization effect of the spray pump, the cleaning agent can be synchronously covered on the inner and outer surfaces of the folding shed. Compared with the traditional step-by-step operation of cleaning the outer side first and then the inner side, the cleaning time of a single folding shed is shortened and the cleaning efficiency is improved.

[0056] The spray pressure, spray angle, and spray time of the spray assembly 2 are controlled to cover the entire surface of the folding tent. The parameters are adjusted according to the degree of dirt on the folding tent. For example, when the dirt is heavy, the spray pressure is increased, the spray time is extended, and the spray angle is adjusted to cover the dead corners. When the dirt is light, the pressure is reduced and the time is shortened. This avoids waste of cleaning agent and material damage caused by over-cleaning of the folding tent. At the same time, it ensures that every part of the folding tent is covered by cleaning agent, thereby improving the cleaning effect and flexibility.

[0057] After the spraying is completed, the folding canopy 4 in the passageway is lowered and removed from the bearing component 1 by the lifting component 3. The electric hoist 31 of the lifting component 3 can smoothly control the descent speed of the folding canopy to avoid collision damage caused by the folding canopy descending too fast. The traveling wheels 11 of the bearing component 1 can push the device to adjust its position, reducing manpower consumption.

[0058] Detailed operation process: 1. Equipment Preparation: Before use, check that all parts of the mechanism are intact and that all connections are secure. Ensure that the storage tank contains a sufficient amount of cleaning agent, and check that the spray pump, pipelines, and spray heads 24 are functioning properly.

[0059] 2. Folding Shelter Lifting: Move the cleaning device to the storage position of the folding shelter 4 in the passageway, place the folding shelter 4 into the frame structure 12, and adjust its position so that the hook 33 can accurately hook onto the lifting point of the folding shelter. Then, by activating the lifting assembly 3, slowly lift the sling 32 to smoothly lift the folding shelter. During the lifting process, carefully observe the state of the folding shelter to ensure it remains balanced and avoids swaying or tilting. Once the folding shelter has been lifted to the appropriate height, it is fully unfolded, and lifting stops.

[0060] 3. Spray Cleaning: After the folding tent is unfolded, start the spray assembly 2. First, adjust the pressure and flow rate of the spray pump according to the degree of dirt on the folding tent and the cleaning requirements to ensure that the cleaning agent is sprayed onto the surface of the folding tent at a suitable pressure and flow rate. Then, turn on the spray head 24, and the cleaning agent is sprayed out from the spray head 24, evenly covering the inner and outer surfaces of the folding tent. During the spraying process, carefully observe the spraying effect to ensure that all parts of the folding tent are covered by the cleaning agent. The spraying time is adjusted according to the degree of dirt on the folding tent and the performance of the cleaning agent, generally 5 to 10 minutes.

[0061] 4. Manual Scrubbing Assistance: After the spray cleaning is completed, the surface of the folding canopy is further scrubbed manually using specialized cleaning tools. During the scrubbing process, special attention is paid to the corners and crevices of the folding canopy, where dirt is prone to remain, to ensure that the dirt in these areas is thoroughly removed. After manual scrubbing is completed, the spray assembly 2 is restarted to rinse the folding canopy again, washing away any remaining cleaning agent and dirt.

[0062] 5. Lowering the Folding Shelter and Resetting the Equipment: After the cleaning work is completed, slowly lower the height of the sling 32 and smoothly return the folding shelter 4 of the passageway to its original position. Then, reset all components of the lifting assembly 3 and the spray assembly 2, turn off the equipment power, clean the site, and complete the entire cleaning operation.

[0063] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
