[0044] Example:

[0045] In a preferred embodiment of the present invention, a boarding operation maintenance warehouse suitable for urban rail vehicles is provided. Figure 1 , 2 As shown in , the maintenance depot is provided with a plurality of maintenance lines 4, which can realize simultaneous maintenance of a plurality of groups of urban rail vehicles. Specifically, the plurality of maintenance lines 4 are arranged in parallel and spaced apart, and the extending direction of the maintenance lines 4 is the longitudinal direction of the maintenance depot, and the horizontal direction perpendicular to the longitudinal direction is the transverse direction, that is, the urban rail vehicles are parked in the maintenance depot along the longitudinal direction.

[0046] Furthermore, a ceiling 2 is provided on the top of the maintenance warehouse, and a plurality of horizontal beams 302 extending in the transverse direction are provided at the bottom of the ceiling 2, and a plurality of support columns 3 are provided vertically below the horizontal beams 302; one end of the support column 3 is fixedly supported on the ground 1, and the other end is fixedly connected to the horizontal beam 302. In order to ensure stable support at various positions of the ceiling 2, in actual settings, the support columns 3 are multiple and are spaced apart in the transverse and longitudinal directions of the maintenance warehouse. Of course, in actual settings, a plurality of longitudinal beams extending in the longitudinal direction are also provided at the bottom of the corresponding ceiling 2, which are correspondingly connected to the horizontal beams 302, and a plurality of support columns 3 are provided at the bottom of the longitudinal beams, which can be optimized according to actual needs and will not be elaborated here. Specifically, support columns 3 are provided on both sides of the maintenance warehouse in the transverse direction, and a plurality of support columns 3 on both sides of the maintenance warehouse are spaced apart in the longitudinal direction.

[0047] Furthermore, each maintenance line 4 includes track units arranged in pairs, and the track units include track beams arranged on the ground 1 and tracks arranged on the top of the track beams, and a maintenance pit 5 of a certain depth is opened longitudinally on the ground 1 between the two track units for maintenance personnel to enter and inspect the bottom of the vehicle. In actual settings, a wastewater ditch is opened on one side of the maintenance pit 5 to collect wastewater after vehicle cleaning; at the same time, a wastewater well 7 is arranged corresponding to the wastewater ditch, which is connected to the wastewater ditch through a number of wastewater pipes 6 for centralized treatment or discharge of wastewater. By arranging multiple wastewater pipes 6 at intervals in the longitudinal direction of the wastewater ditch, the accumulation of wastewater in the wastewater ditch can be effectively avoided, the efficiency of wastewater discharge can be improved, and the stability of the wastewater ditch setting can be guaranteed to a certain extent. Once a wastewater pipe 6 is blocked, other wastewater pipes 6 can still discharge wastewater normally. In addition, the wastewater well 7 can be set for a single maintenance line 4, or it can be connected to multiple wastewater ditches at the same time, such as Figure 1 as shown in .

[0048] More specifically, in order to realize the maintenance of the inside and top of the vehicle, a work platform is provided for each maintenance line 4 in the maintenance depot, and the work platform includes a single-side maintenance platform provided corresponding to the two outermost maintenance lines 4 in the transverse direction and a double-side maintenance platform provided between two adjacent maintenance lines 4 in the middle of the maintenance depot. In actual setting, there are several possible setting forms:

[0049] (1) When there is only one maintenance line 4 in the maintenance warehouse, it is only necessary to set up a single-side maintenance platform for the maintenance line 4;

[0050] (2) When two maintenance lines 4 are arranged in parallel in the maintenance depot, a single-side maintenance platform can be arranged on both sides of the two maintenance lines 4 that are away from each other, or a double-side maintenance platform can be arranged between the two maintenance lines 4;

[0051] (3) When there are multiple (greater than 2) maintenance lines 4 arranged in parallel in the maintenance depot, and the number of maintenance lines 4 is an odd number, a single-side maintenance platform can be arranged on one lateral side of the maintenance depot corresponding to one maintenance line 4, and double-side maintenance platforms can be arranged corresponding to the remaining maintenance lines 4;

[0052] (4) When there are multiple maintenance lines 4 (greater than 2) arranged in parallel in the maintenance depot, and the number of maintenance lines 4 is an even number, a single-sided maintenance platform can be set on both lateral sides of the maintenance depot corresponding to the two maintenance lines 4 on both sides, and a double-sided maintenance platform can be set corresponding to the remaining maintenance lines 4.

[0053] Specifically, the single-side maintenance platform in the preferred embodiment is as follows: Figure 1 , 3As shown in the figure, it includes a boarding platform 103 and a climbing platform 204 arranged at intervals in the vertical direction, which are used for boarding and climbing operations of urban rail vehicles respectively. The boarding platform 103 and the climbing platform 204 extend horizontally in the longitudinal direction respectively, and the extension length of the two in the longitudinal direction preferably corresponds to the longitudinal length of the urban rail vehicle.

[0054] Furthermore, the two platforms in the single-side maintenance platform are provided with platform suspension rods 401, which extend vertically and are arranged at intervals in the longitudinal direction. At the same time, the top of the platform suspension rod 401 is fixedly connected to the crossbeam 302, one side of the lateral side of the top platform 204 is fixed to the middle of the platform suspension rod 401, and the other side extends toward the corresponding maintenance line 4; one side of the lateral side of the boarding platform 103 is fixed to the bottom of the platform suspension rod 401, and the other side extends toward the corresponding maintenance line 4. Through the fixed connection of the two platforms with multiple platform suspension rods 401 in the longitudinal direction, the stable setting of the two platforms can be achieved.

[0055] Preferably, in order to ensure the stability of the two platforms and the platform suspension rods 401, a plurality of first support rods 402 are arranged on the side of each platform suspension rod 401 away from the two platforms. The first support rods 402 are preferably arranged horizontally, with one end connected to the platform suspension rod 401 and the other end connected to the support columns 3 located on both sides of the maintenance depot, so as to ensure the stability of the two platforms and avoid the shaking of the platform suspension rods 401. In actual setting, the first support rods 402 corresponding to one platform suspension rod 401 are two vertically spaced apart, and the two first support rods 402 are respectively connected to the setting positions of the boarding platform 103 and the top platform 204, such as Figure 3 as shown in .

[0056] Furthermore, guardrails are respectively arranged on both sides of the boarding platform 103 and the top platform 204, namely, a second-layer guardrail 102 and a third-layer guardrail 203, to ensure the safety of maintenance personnel when working on the two platforms. In actual settings, due to the setting requirements of the train running limit and the arc-shaped setting form on both sides of the top of the vehicle, a gap of a certain width is formed between the vehicle and the edge of the top platform 204 after the vehicle stops on the maintenance line 4. In view of this, a flip ferry 202 is arranged on the side of the top platform 204 close to the maintenance line 4, which is used to fill the gap between the edge of the top platform 204 and the roof of the vehicle to ensure the safety of maintenance personnel when performing top operations. In a preferred embodiment, a rotating mechanism (such as a servo rotating motor) is arranged corresponding to the flip ferry 202, which is preferably arranged at the end of the top platform 204 or arranged below its end, and one side of the flip ferry 202 is rotatably connected to the rotating mechanism. Through the control of the rotating mechanism, the flip ferry 202 can be converted from a vertical state to a horizontal state. In actual arrangement, the flip ferry 202 may be arranged in sequence in the longitudinal direction for multiple or continuously, and the rotating mechanism provided for the same flip ferry 202 may be one or multiple. In addition, in order to ensure safe boarding from the boarding platform 103, in a preferred embodiment, a flip ferry 202 may be provided on one side of the boarding platform 103 to fill the gap between the boarding platform 103 and the vehicle door.

[0057] Accordingly, a boarding platform ladder 101 is provided between the ground 1 and the boarding platform 103, and a climbing platform ladder 201 is provided between the boarding platform 103 and the climbing platform 204. Figure 2 , 3 As shown in the figure, it is for maintenance personnel to walk up and down.

[0058] Furthermore, a corresponding single-side maintenance platform is provided with a top maintenance auxiliary mechanism, such as Figure 5 As shown in , it is arranged on the side of the maintenance line 4 away from the single-side maintenance platform, as shown in Figure 1As shown in , a protective net is used to prevent maintenance personnel from falling from the other side of the roof. Specifically, the roof maintenance auxiliary mechanism includes a plurality of protective net hanging rods 405 arranged at intervals in the longitudinal direction, which are arranged in the vertical direction, one end of which is fixedly connected to the crossbeam 302, and the other end of which extends downward to one side of the top of the vehicle. At the same time, a rotatable flip ferry 202 is arranged on the side of the protective net hanging rod 405 close to the corresponding maintenance line 4, and its setting form is the same as the setting form of the flip ferry 202 on the side of the boarding platform 103, which will not be repeated here. By setting the flip ferry 202 on the protective net hanging rod 405, the gap between the roof and the protective net hanging rod 405 can be blocked. In actual setting, a protective net is arranged between each flip ferry 202, so that when each flip ferry 202 is rotated to a horizontal state, an auxiliary maintenance platform along the longitudinal direction can be formed, and the auxiliary maintenance platform can just block the gap between the roof and the protective net hanging rod 405. At the same time, a protective net is vertically arranged between each protective net hanging rod 405, so as to form a protective net structure on one side of the vehicle roof.

[0059] Preferably, a protective net hanging rod 301 is arranged on the side of the protective net hanging rod 405 away from the maintenance line 4, one end of which is connected to the crossbeam 302, and the other end is connected to the protective net hanging rod 405. By setting the protective net hanging rod 301, the setting stability of the protective net hanging rod 405 and the protective net can be effectively guaranteed, and the shaking of the protective net hanging rod 405 can be avoided. Figure 5 In actual setting, the connection form between the protective net hanging rod 405 and the crossbeam 302 is preferably as follows: Figure 6 As shown in FIG. 4 , the end of the protective net hanging rod 405 is provided with a flange, and the end flange of the protective net hanging rod 405 is connected and fastened to the crossbeam 302 through a plurality of fastening bolts 303. At the same time, the protective net hanging rod 301 in the preferred embodiment is rotatably connected to the crossbeam 302 through a hinge 304, as shown in FIG. Figure 7 As shown in the figure, the hinge 304 is connected to the crossbeam 302 through a plurality of fastening bolts 303; accordingly, the other end of the protection net suspension rod 301 is rotatably connected to the protection net hanging rod 405.

[0060] In addition, in order to ensure that both sides of each maintenance line 4 can realize boarding operations, a single-side maintenance platform can be set on the other side of the maintenance line 4 where the single-side maintenance platform is set, and the two single-side maintenance platforms can respectively perform boarding operations and top climbing operations, thereby improving the efficiency of maintenance operations. However, it is also possible to only set the boarding platform 103 in one of the single-side maintenance platforms without setting the top climbing platform 204, and the position of the single-side maintenance platform corresponding to the roof operation area is correspondingly provided with a flip board 202 and a protective net.

[0061] Furthermore, the double-sided maintenance platform in the preferred embodiment is as follows Figure 4As shown in , it is arranged between two adjacent maintenance lines 4 and can be used for simultaneous maintenance of two trains of vehicles on the two maintenance lines 4. In actual setting, the double-sided maintenance platform can be regarded as a corresponding combination of two single-sided maintenance platforms arranged away from each other, that is, the two climbing platforms 204 and the two boarding platforms 103 on the double-sided maintenance platform are respectively arranged on the two sides away from each other of the two platform suspension rods 401; obviously, the structure on both sides of the double-sided maintenance platform can refer to the structural description of the aforementioned single-sided maintenance platform, so it will not be repeated here. At the same time, a second support rod 404 is arranged laterally between the two laterally opposite platform suspension rods 401 in the double-sided maintenance platform. In the preferred embodiment, the second support rod 404 is two vertically spaced apart, and the two second support rods 404 are respectively arranged at the setting positions of the boarding platform 103 and the climbing platform 204. Preferably, a reinforcement rod 403 is respectively arranged on the two platform suspension rods 401, one end of which is connected to the platform suspension rod 401, and the other end is connected to the middle part of the second support rod 404, forming a triangular support structure, such as Figure 4 As shown in

[0062] By setting up the double-sided maintenance platforms, two trains of urban rail vehicles can be simultaneously maintained, reducing the setting space of the maintenance platforms, so that as many maintenance lines 4 as possible can be set up in the limited space maintenance depot, thereby improving the efficiency of urban rail vehicle maintenance.

[0063] Furthermore, a climbing maintenance auxiliary mechanism is provided on the side of the two maintenance lines 4 corresponding to the double-sided maintenance platform away from the double-sided maintenance platform, and a suspended protective net is provided on the climbing maintenance auxiliary mechanism to ensure the safety of climbing maintenance on the corresponding vehicle.

[0064] In actual settings, the lengths of each boarding platform 103 and each climbing platform 204 are preferably the same, and are further preferably the same as the column spacing of the support columns 3 on both sides of the maintenance depot in the longitudinal direction. At the same time, it is preferred that a number of cargo transfer platforms be provided on the side away from the maintenance line 4 corresponding to each boarding platform 103, which are used for the transfer and storage of cargo, equipment and maintenance tools on the vehicle. Secondly, the treads of the boarding platform 103 and the climbing platform 204 are preferably made of steel gratings or patterned steel plates. In addition, for the maintenance lines 4 arranged on both sides of the maintenance depot in the horizontal direction, a single-sided maintenance platform is provided on one side, and a climbing maintenance auxiliary mechanism can be provided on the other side, or a single-sided maintenance platform or a double-sided maintenance platform can be provided. In this way, it can be ensured that the vehicles on this maintenance line 4 can achieve boarding and climbing on both sides, thereby further improving the efficiency of maintenance. This can shorten the maintenance time as much as possible for vehicles that need to be repaired urgently.

[0065] Further preferably, each flip ferry 202 has a self-locking function, preferably an electric wind drive, and adopts a PLC centralized and segmented control method to ensure the safety needs of maintenance personnel climbing to the top. At the same time, a flip ferry in place indicator light is set on each climbing platform to facilitate maintenance personnel to observe whether the ferry is flipped or retracted in place. In addition, a safety lock mechanism is set in place for each flip ferry 202 to safely lock the flip ferry 202 in the corresponding position.

[0066] The boarding and maintenance warehouse suitable for urban railway vehicles in the present invention has a simple layout, high maintenance efficiency and safety, can make full use of the maintenance space in the maintenance warehouse, reduce space waste, reduce the maintenance cost of urban railway vehicles, ensure the safety of boarding and climbing maintenance, and has good application prospects and promotion value.

[0067] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
