[0002] At present, the suspended monorail transit system suspends the track beam above the ground through columns, forming a simply supported stress system of box girders. The vehicle is hung below the bogie, and the bogie travels inside the box girder with a lower opening. The lower bottom surface inside the box girder is the running surface, and the side surface inside is the guiding surface.

At the same time, it should be noted that the terms "first", "second", etc. in the description, claims, and above - mentioned drawings of the present invention are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0036] Combined with Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a suspended monorail inspection vehicle (hereinafter referred to as the inspection vehicle), including: a traction device 1, which is adapted to be arranged inside the track beam 100 and travel along the length direction of the track beam 100; and a lifting device 2, which is hung below the traction device 1. The lifting device 2 is used to carry the operator 200 and / or operating equipment and transport them to the bottom or the outside of the track beam 100. The lifting device 2 includes a lifting mechanism 21 and an extended working platform 23 arranged on the lifting mechanism 21. The lifting mechanism 21 is adapted to drive the extended working platform 23 to lift. The extended working platform 23 is adapted to extend and contract along the width direction of the track beam 100.

[0037] In this embodiment, the track beam 100 is generally a box beam structure with a cavity inside. The traction device 1 is arranged in the cavity of the track beam 100, and an opening is provided at the lower end of the track beam 100 to facilitate the connection between the traction device 1 arranged in the track beam 100 and the lifting device 2 arranged outside the track beam 100. The inspection work outside the track beam 100 mainly includes the maintenance or installation of accessories on the bottom and outer side of the track beam 100. In this embodiment, the maintenance of the outside of the track beam 100 can be carried out manually, such as using the operator 200 to carry out the maintenance operation; or it can be carried out by using operation equipment such as intelligent mechanical equipment like robots or robotic arms to achieve automatic maintenance. For the convenience of description, the following takes the manual method as an example for illustration. When inspecting the bottom outside the track beam 100, the operator 200 stands on the extensible workbench 23, and the traction device 1 travels along the length direction of the track beam 100 in the track beam 100, driving the lifting device 2 suspended below the traction device 1 to move together. When moving to the working position that needs to be maintained, the traction device 1 stops, and the lifting mechanism 21 of the lifting device 2 drives the extensible workbench 23 to rise to the working position at the bottom of the track beam 100, and the operator 200 can carry out maintenance operations on the bottom of the track beam 100 on the extensible workbench 23. In order to increase the operating space of the operator 200, at this time, the extensible workbench 23 can be selected to be extended and opened to increase the activity space and operating space of the operator 200. When inspecting the outer side of the track beam 100, the traction device 1 drives the lifting device 2 to move below the position on the outer side of the track beam 100 that needs to be maintained, as Figure 8 shown. After the lifting mechanism 21 drives the extensible workbench 23 to rise to be close to the bottom of the track beam 100, the extensible workbench 23 extends and opens along the width direction of the track beam 100, as Figure 9 shown. The lifting mechanism 21 drives the opened extensible workbench 23 to rise until it reaches the outer side of the track beam 100, as Figure 10 shown. The operator 200 can carry out maintenance operations on the outer side of the track beam 100 on the extensible workbench 23. Among them, the length direction of the track beam 100 refers to the Figure 1 Y-axis direction in Figure 1 and correspondingly, the width direction of the track beam 100 refers to the X-axis direction in .

[0038] In this way, using the suspended monorail inspection vehicle as a special device to inspect the outside of the track beam 100 can prevent operators from walking on the upper end face of the track beam 100 to install or repair accessories on the outside of the track beam 100, greatly improving the safety and work efficiency during installation or repair operations. At the same time, by setting the extended workbench 23 to extend and open when the operator 200 repairs the bottom of the track beam 100, the activity space and operating space of the operator 200 are increased, or when the operator 200 repairs the outer side of the track beam 100, it extends and opens to facilitate the lifting device 2 to lift the opened extended workbench 23 to the outside of the track beam 100, so as to facilitate the operator 200 to repair the outer side of the track beam 100.

[0039] Furthermore, a fence is provided on the extended workbench 23 to prevent the operator 200 from falling, so as to further ensure the safety of the operator 200 during work.

[0040] Optionally, as shown in Figures 3 to 5 the lifting device 2 further includes a connecting mechanism 22. The extended workbench 23 is arranged at the upper end of the lifting mechanism 21, and the upper end of the lifting mechanism 21 is connected to the extended workbench 23. One end of the connecting mechanism 22 is connected to the bottom of the lifting mechanism 21, and the other end is connected to the lower end of the traction device 1.

[0041] In this embodiment, the connecting mechanism 22 may penetrate through the lifting mechanism 21 and the extensible working platform 23. The lower end of the lifting mechanism 21 is fixedly connected or detachably connected to the lower end of the connecting mechanism 22, and the upper end of the lifting mechanism 21 and the extensible working platform 23 are both optionally in contact with the middle part of the connecting mechanism 22 and form a sliding connection at the contact point. At this time, when the lifting mechanism 21 moves up and down, it drives the extensible working platform 23 to slide up and down on the connecting mechanism 22; or the upper end of the lifting mechanism 21 and the extensible working platform 23 are both optionally not in contact with the connecting mechanism 22. At this time, when the lifting mechanism 21 moves up and down, it drives the extensible working platform 3 to move up and down along the connecting mechanism 22. In this embodiment, the connecting mechanism 22 may also be arranged on the same side of the lifting mechanism 21 and the extensible working platform 23. For example, it is arranged on one of the front side, rear side, left side, and right side of the lifting mechanism 21 and the extensible working platform 23, and the lower end of the lifting mechanism 21 is fixedly connected or detachably connected to the lower end of the connecting mechanism 22. The upper end of the lifting mechanism 21 and the extensible working platform 23 are both optionally in contact with the middle part of the connecting mechanism 22 and form a sliding connection at the contact point. At this time, when the lifting mechanism 21 moves up and down, it drives the extensible working platform 23 to slide up and down on the connecting mechanism 22. In actual production, the setting method can be selected according to needs, and no specific limitation is made here. The lifting mechanism 21 may be arranged above the extensible working platform 23 or below the extensible working platform 23. When the lifting mechanism 21 is arranged above the extensible working platform 23, the upper end of the lifting mechanism 21 is connected to the lower end of the traction device 1, and the lower end of the lifting mechanism 21 is connected to the extensible working platform 23, so that the connecting mechanism 22 does not need to be provided. However, in this way, when a fault such as a fracture occurs in the lifting mechanism 21, it is easy to cause the extensible working platform 23 to break away from the connection protection of the lifting mechanism 21, resulting in the extensible working platform 23 falling from a high altitude. Based on this, in this embodiment, it is preferably to arrange the lifting mechanism 21 below the extensible working platform 23 and set the connecting mechanism 22 to connect the extensible working platform 23, the lifting mechanism 21, and the traction device 1. In this way, even if the lifting mechanism 21 breaks down, the extensible working platform 23 can be hung on the connecting mechanism 22 and will not fall off directly, thereby further ensuring the safety of the operator 200 during maintenance operations and improving the safety of the inspection vehicle during use.

[0042] Further, the lifting mechanism 21 is symmetrically arranged with respect to the connecting mechanism 22, and the extensible working platform 23 is also symmetrically arranged with respect to the connecting mechanism 22. One end of the connecting mechanism 22 is connected to the bottom of the lifting mechanism 21, and the other end penetrates through the lifting mechanism 21 and the extensible working platform 23 and is connected to the lower end of the traction device 1.

[0043] The lifting mechanism 21 and the extensible working platform 23 can be of an asymmetric structure or a symmetric structure. In this embodiment, it is preferably that both the lifting mechanism 21 and the extensible working platform 23 are of a symmetric structure and are symmetrically arranged with respect to the connecting mechanism 22 respectively, so as to simplify the structures of the lifting mechanism 21 and the extensible working platform 23 and facilitate processing and manufacturing. At the same time, the connecting mechanism 22 is arranged through the lifting mechanism 21 and the extensible working platform 23, so that the lifting mechanism 21 and the extensible working platform 23 are sleeved on the connecting mechanism 22, so as to ensure that the extensible working platform 23 can be hung on the connecting mechanism 22 when the lifting mechanism 21 has a fracture failure, preventing the extensible working platform 23 and the operator 200 standing on the extensible working platform 23 from falling, and further ensuring the safety of the operator 200 during operation.

[0044] As Figure 8 shown, in the initial state, the lifting mechanism 21 of the lifting device 2 is in a contracted state, and the extensible working platform 23 is not extended (i.e., not opened). At this time, the height of the lifting mechanism 21 is the smallest, and the length of the extensible working platform 23 is the smallest. Among them, the height of the lifting mechanism 21 refers to the dimension of the lifting mechanism 21 in the vertical direction (i.e., Figure 1 the Z-axis direction in Figure 1 ), and the length of the extensible working platform 23 refers to the dimension of the extensible working platform 23 in the left-right direction (i.e., Figure 1 the X-axis direction in Figure 1 ). When the extensible working platform 23 extends and opens along the width direction of the track beam 100, the length of the extensible working platform 23 increases. When the lifting mechanism 21 extends to drive the extensible working platform 23 to rise, the height of the lifting mechanism 21 increases.

[0045] Optionally, as shown in Figure 5 , the lifting mechanism 21 includes a base 211, a scissor assembly 212 arranged on the base 211, and a telescopic assembly 213 arranged on the scissor assembly 212. One end of the connecting mechanism 22 far from the traction device 1 is fixed on the base 211, and the telescopic assembly 213 drives the scissor assembly 212 to extend or fold to drive the extensible working platform 23 to perform a lifting motion.

[0046] In this embodiment, the lower end of the connecting mechanism 22 is fixed to the lower end of the base 211, and the upper end of the connecting mechanism 22 is connected to the lower end of the traction device 1. Using a scissor lift as the lifting mechanism 21, it is widely used in high-altitude operations, and its scissor mechanical structure enables the extensible working platform 23 to have a high load-bearing capacity, and can ensure that the extensible working platform 12 has high stability during the rising and falling processes, higher safety, and higher work efficiency.

[0047] Furthermore, the telescopic assembly 213 is a telescopic hydraulic cylinder, which has stable control and high load-bearing capacity.

[0048] Optionally, in combination withFigure 5 As shown, the connecting mechanism 22 has a column structure, and a groove structure 221 is provided on the column structure, and the groove structure 221 penetrates the column structure along the width direction of the track beam 100.

[0049] In this embodiment, by providing the groove structure 221 on the connecting mechanism 22 as a weight-reducing hole, the self-weight of the connecting mechanism 22 is reduced, thereby reducing the weight of the inspection vehicle and the load of the traction device 1.

[0050] Optionally, the groove structure 221 is in the shape of a long strip hole, and a plurality of groove structures 221 are provided, and the plurality of groove structures 221 are arranged at intervals in the up-down direction. In this way, by arranging a plurality of groove structures 221 at intervals, a long cavity span in the middle part of the connecting mechanism 22 is prevented, and the structural strength of the middle part is reduced, so that the self-weight of the connecting mechanism 22 is further reduced on the premise of ensuring the structural strength of the connecting mechanism 22.

[0051] Specifically, as Figure 3 shown, the column structure includes a column body 222 and a connecting plate 223. The groove structure 221 is provided on the column body 222, and the connecting plate 223 is provided at the upper end and / or the lower end of the column body 222. The connecting plate 223 is adapted to be connected to the traction device 1 or the base 211.

[0052] In this embodiment, by providing the connecting plate 223 at the upper end and / or the lower end of the column body 222, it is convenient to increase the contact area between the column body 222 and the traction device 1 or between the column body 222 and the base 211 of the lifting mechanism 21, and improve the stability when the column body 222 is connected to the traction device 1 or the lifting mechanism 21.

[0053] Optionally, as Figure 5 shown, the column structure further includes a reinforcing rib 224, and the reinforcing rib 224 is provided at the upper end and / or the lower end of the column body 222. In this way, the structural strength at the upper end and / or the lower end of the column structure is increased, and the stability when the upper end of the column structure is connected to the traction device 1 or the stability when the lower end of the column structure is connected to the base 211 is ensured.

[0054] Further, a plurality of reinforcing ribs 224 are provided, and the plurality of reinforcing ribs 224 are arranged circumferentially around the column body 222. In this way, by arranging a plurality of reinforcing ribs 224 circumferentially on the column body 222, the structural strength of the column body 222 is further enhanced, and the tensile performance of the column body 222 is improved.

[0055] Optionally, as Figure 5As shown, there is a spacing between the reinforcing rib 224 and the connecting plate 223 in the vertical direction. In this way, when only one end of the connecting mechanism 22 is provided with the connecting plate 223 and the reinforcing rib 224, the end provided with the connecting plate 223 and the reinforcing rib 224 can be used as the lower end of the connecting mechanism 22. When assembling the lifting mechanism 21 and the connecting mechanism 22, the base 211 of the lifting mechanism 21 can be clamped between the reinforcing rib 224 and the connecting plate 223, so that the reinforcing rib 224 can prevent the base 211 from moving upward, and the connecting plate 223 can prevent the base 211 from moving downward, ensuring the firmness when the connecting mechanism 22 is connected to the base 211; and when both the upper and lower ends of the connecting mechanism 22 are provided with the reinforcing rib 224 and the connecting plate 223, it is not necessary to distinguish which end of the connecting mechanism 22 is used as the lower end to connect with the base 211, improving the versatility of the connecting mechanism 22 and also the efficiency during assembly.

[0056] Optionally, in combination with Figure 5 As shown, the extensible working platform 23 includes a fixed working platform 231 provided with a through hole 2311, a driving mechanism, and a movable working platform 232 arranged at the end of the fixed working platform 231. The connecting mechanism 22 penetrates the fixed working platform 231 at the through hole 2311. One end of the driving mechanism is connected to the fixed working platform 231, and the other end is connected to the movable working platform 232, and the driving mechanism is adapted to drive the movable working platform 232 to extend and contract along the width direction of the track beam 100.

[0057] In this embodiment, the movable working platform 232 can be arranged at one end of the fixed working platform 231 in the width direction of the track beam 100, or the movable working platform 232 can be arranged at both ends of the fixed working platform 231 in the width direction of the track beam 100. That is, the extensible working platform 23 can extend unidirectionally or bidirectionally. In this embodiment, it is preferably that the extensible working platform 23 extends bidirectionally to increase the operating space of the working platform and facilitate the maintenance of the outer sides on both sides of the track beam 100. The through hole 2311 is arranged at the middle position of the fixed working platform 231, and the connecting mechanism 22 penetrates the extensible working platform 23 at the through hole 2311, so that the extensible working platform 23 is sleeved on the connecting mechanism 22. In this way, the connecting mechanism 22 can be used as a guide post to guide the lifting of the extensible working platform 23 and prevent the extensible working platform 23 from shaking during the lifting process.

[0058] Optionally, in combination with Figure 5 and Figure 6 As shown, the through hole 2311 has a first hole wall and a second hole wall arranged oppositely in the width direction of the track beam 100, and a connecting beam 2312 is arranged in the through hole 2311. One end of the connecting beam 2312 is connected to the first hole wall, and the other end passes through the groove structure 221 and is connected to the second hole wall.

[0059] In this embodiment, the first hole wall and the second hole wall of the through hole 2311 that are oppositely arranged in the width direction of the track beam 100 are the two hole walls of the through hole 2311 in the left-right direction (i.e., Figure 2 the X-axis direction in Figure 2 ). One end of the connecting beam 2312 is connected to the left hole wall of the through hole 2311, and the other end is connected to the right hole wall of the through hole 2311. In this way, when the extensible workbench 23 moves up and down, the connecting beam 2312 can move up and down within the groove structure 221. Not only can the two groove walls of the groove structure 221 in the up-down direction be used to limit the lifting displacement of the connecting beam 2312, and further limit the lifting displacement of the lifting mechanism 21, but also when the lifting mechanism 21 fails, it can ensure that the lifting mechanism 21 can hang on the groove structure 221 of the connecting mechanism 22 and will not fall directly, thereby playing a further protective role for the operator 200 standing on the extensible workbench 23.

[0060] Optionally, the size of the groove structure 221 in the vertical direction is greater than or equal to the lifting stroke of the lifting mechanism 21. Here, the lifting stroke of the lifting mechanism 21 refers to the height that the extensible workbench 23 rises when the lifting mechanism 21 rises from the initial contracted state to the designated position. In this way, it is prevented that the connecting beam 2312 cannot be lifted to the designated position due to being blocked by the groove walls of the groove structure 221 in the up-down direction, and it is ensured that the lifting mechanism 21 will not interfere with the groove walls of the groove structure 221 in the up-down direction after being lifted along the connecting mechanism 22 to the designated position.

[0061] Optionally, the connecting beam 2312 is detachably connected to the first hole wall and the second hole wall. In this way, a detachable connection is formed between the extensible workbench 23 and the connecting mechanism 22, improving the disassembly and assembly efficiency of the inspection vehicle.

[0062] Optionally, as Figure 7 shown, the traction device 1 includes a vehicle body 11, a traveling mechanism 12 arranged on the vehicle body 11, a power assembly 13, and a control assembly 14; the power assembly 13 and the control assembly 14 drive the traveling mechanism 12 to travel along the traveling surface inside the track beam 100. Here, the traveling surface inside the track beam 100 refers to the bottom surface of the inner cavity of the track beam 100.

[0063] Specifically, the traveling mechanism 12 includes traveling wheels, and the traveling wheels are adapted to roll along the traveling surface inside the track beam 100 and support the entire vehicle body 11 and components such as the power assembly 13 and the control assembly 14 arranged on the vehicle body 11; the power assembly 13 is a battery assembly, and the control assembly 14 includes a reduction gearbox 141 and an electrical control box 142.

[0064] Optionally, the traction device 1 further includes a guiding mechanism 15 provided on the vehicle body 11. The guiding mechanism 15 is adapted to move along the inner side wall of the track beam 100 to guide the traction device 1. In this way, by providing the guiding mechanism 15 on the vehicle body 11 to guide the running of the traction device 1 in the track beam 100, it is possible to prevent the running mechanism 12 from shifting during running, resulting in interference between the column body 222 of the connecting mechanism 22 and the edge of the lower opening of the track beam 100. Moreover, there is no need to lay guiding structures such as tracks or rail grooves on the running surface of the track beam 100 to guide the running mechanism 12, reducing the change to the structure of the track beam 100, thereby simplifying the structure of the track beam 100.

[0065] Further, the guiding mechanism 15 includes guiding wheels. The guiding wheels are adapted to roll along the inner side wall of the track beam 100 to guide the traction device 1. In this way, by rolling the guiding wheels on the inner side wall of the track beam 100 for guiding, the structure is simple and easy to manufacture.

[0066] Another embodiment of the present invention provides an inspection method, using the suspended monorail inspection vehicle described in any one of the above, including the following steps:

[0067] Step a: The lifting device 2 of the suspended monorail inspection vehicle carries the operating personnel 200 and / or operating equipment. The traction device 1 of the suspended monorail inspection vehicle drives the lifting device 2 to move along the length direction of the track beam 100 below the track beam 100, and transports the operating personnel 200 and / or operating equipment to the designated position; wherein, the designated position refers to the position below the part that needs to be repaired at the bottom or outside of the track beam 100.

[0068] Step b: When it is necessary to repair the bottom of the track beam 100, the lifting mechanism 21 of the lifting device 2 drives the extensible working platform 23 of the lifting device 2 to rise, and transports the operating personnel 200 and / or operating equipment to the working position at the bottom of the track beam 100.

[0069] And / or, Step c: When it is necessary to repair the outer side surface of the track beam 100, the extensible working platform 23 of the lifting device 2 extends and opens, and the lifting mechanism 21 of the lifting device 2 drives the extensible working platform 23 to rise, and transports the operating personnel 200 and / or operating equipment to the working position on the outer side surface of the track beam 100.

[0070] There are three situations in the inspection method of this embodiment. The first situation includes step a and step b, the second situation includes step a and step c, and the third situation includes step a, step b, and step c. When using the suspended monorail inspection vehicle for inspection operations, according to actual usage needs, the corresponding inspection steps are selected in an alternative manner for inspection operations. For example, when only the bottom of the track beam 100 needs to be inspected, the first situation in the inspection method is used for inspection operations; when only the outer side of the track beam 100 needs to be inspected, the second situation in the inspection method is used for inspection operations; when both the bottom and the outer side of the track beam 100 need to be inspected, the third situation in the inspection method is used for inspection operations. In this way, through step a and step b, the inspection vehicle can perform maintenance and accessory installation on the bottom of the track beam 100, or through step a and step c, the inspection vehicle can perform maintenance and accessory installation on the outer side of the track beam 100, or through step a to step c, the inspection vehicle can perform maintenance and accessory installation on the bottom and the outer side of the track beam 100, greatly improving the safety and efficiency of the operator 200 during operation, and the operation is simple and the degree of automation is high.

[0071] When inspecting the bottom outside the track beam 100, the operator 200 stands on the extended workbench 23, and the traction device 1 travels along the length direction of the track beam 100 inside the track beam 100, driving the lifting device 2 suspended below the traction device 1 to move together. When moving to the designated position, the traction device 1 stops moving, and the lifting mechanism 21 of the lifting device 2 drives the extended workbench 23 to rise to the working position at the bottom of the track beam 100, and the operator 200 can perform maintenance operations on the bottom of the track beam 100 on the extended workbench 23. During the maintenance process, the operator 200 can choose whether to extend and open the extended workbench 23 according to actual needs to increase the operation space and activity space.

[0072] As Figures 8 to 10 shown, when inspecting the outer side outside the track beam 100, the traction device 1 drives the lifting device 2 to move below the position on the outer side of the track beam 100 that needs to be maintained. After the lifting mechanism 21 drives the extended workbench 23 to rise close to the bottom of the track beam 100, the extended workbench 23 extends and opens along the width direction of the track beam 100, and the lifting mechanism 21 drives the opened extended workbench 23 to rise until it reaches the outer side of the track beam 100, and the operator 200 can perform maintenance operations on the outer side of the track beam 100 on the extended workbench 23.

[0073] Although the present disclosure is disclosed as above, the scope of protection of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the scope of protection of the present invention.
