Description

Technical Field

[0001] The utility model relates to the technical field of rail transit maintenance, in particular to an air-conditioning unit conveyor line. Background Technique

[0002] The air-conditioning unit is an indispensable part of passenger rail transit tools such as high-speed trains and bullet trains. When problems occur in the air-conditioning unit and maintenance operations are required, it often needs to be disassembled and sent to the maintenance site for maintenance through a conveyor line. Currently, when the air-conditioning unit is sent for inspection, it is pushed forward on the conveyor line, and this push is a non-powered push. Personnel follow the air-conditioning unit forward, which poses potential safety hazards and is time-consuming and laborious.

[0003] For the above problems, the invention patent application with the publication number of CN110976411A provides an automatic conveyor ultrasonic cleaning device and cleaning method for high-speed rail air-conditioning shells, including a frame and an ultrasonic cleaning tank inside the frame.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined. In addition, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] As Figures 1-5As shown in the figure, the utility model provides an air conditioner unit conveyor line, which includes: a non-powered conveyor line 1, a powered conveyor line 3, and a lifting conveyor assembly 2 arranged between the two. Among them, the lifting conveyor assembly 2 includes two sets of lifting platforms 201 arranged oppositely and connecting conveyor lines 202 respectively arranged on their tops. Among them, the connecting conveyor line 202 can be docked with the non-powered conveyor line 1 or the powered conveyor line 3 as the lifting platform 201 rises and falls. The air conditioner unit 5 is first placed on the non-powered conveyor line 1 by a jacking and lifting trolley, and then is pushed by the non-powered conveyor line 1 to the connecting conveyor line 202. Under the action of the lifting platform 201, it can be lifted or lowered and conveyed to the powered conveyor line 3, and then automatically conveyed to the maintenance station.

[0032] In this embodiment, the lifting platform 201 is a scissor-type lifting platform, which is lifted by hydraulic drive, is convenient to control and has stable lifting. It can adapt to the lifting of the relatively heavy air conditioner unit 5. The connecting conveyor line 202 is horizontally fixed on the top of the scissor-type lifting platform, and its two ends are close to the edges of the lifting platform 201. After the height is lifted or lowered, the two ends can be respectively docked with the non-powered conveyor line 1 or the powered conveyor line 3, so that the air conditioner unit 5 can be pushed by the non-powered conveyor line 1 to the connecting conveyor line 202, and after the height is adjusted, it is conveyed to the maintenance station for maintenance operations.

[0033] As a preferred solution, the non-powered conveyor line 1, the powered conveyor line 3, and the connecting conveyor line 202 all include a frame 10, a plurality of rollers 8 rotatably installed inside the frame 10, and retaining rings 9 installed at both ends of the surface of the rollers 8. As Figure 2 shown, it is the structure diagram of the non-powered conveyor line 1. The powered conveyor line 3 and the connecting conveyor line 202 have the same or similar structures, and the functions they implement are the same. In this embodiment, guide strips 4 are respectively arranged on both sides of the bottom of the air conditioner unit 5. When the air conditioner unit 5 is driven and conveyed along the rollers 8 on the surfaces of the non-powered conveyor line 1, the connecting conveyor line 202, and the powered conveyor line 3, the guide strips 4 are limited inside the retaining rings 9. Through the guide strips 4, it can be avoided that the transmission components such as the rollers 8 directly contact the air conditioner unit 5, resulting in its compression damage, and the retaining rings 9 are used to guide the guide strips 4 to avoid tilting during the conveying process, thereby causing the air conditioner unit to be conveyed offset.

[0034] In this embodiment, the non-powered conveyor line 1 and the powered conveyor line 3 further include a guard plate 6 and support feet 7. Among them, the guard plate 6 is arranged at the bottom of the frame 10, and the number of support feet 7 is multiple groups, which are symmetrically installed on both sides of the bottom of the guard plate 6 respectively. Through the guard plate 6 and the support feet 7, support can be provided for the frame 10 and the transmission components. Among them, the support feet 7 can adjust the levelness of the surface of the frame 10.

[0035] In this embodiment, the power transmission line 3 and the connecting transmission line 2 further include a power device. Through the power device, power can be provided for the air-conditioning unit 5 to be conveyed on its surface. The power device includes a motor 14, a power transmission shaft 11 and a power roller 15. Among them, the power transmission shaft 11 is in transmission connection with the output shaft of the motor 14. Sprockets 13 are respectively arranged on the output shaft of the motor 14, at both ends of the power transmission shaft 11, at one end of the power roller 15, and at the end parts of the rollers 8 on the power transmission line 3 and the connecting transmission line 202. The motor 14 and the power transmission shaft 11 are in transmission connection through the sprockets 13 and the driving chain; the power transmission shaft 11, the power roller 15 and the rollers 8 on the power transmission line 3 and the connecting transmission line 2 are in transmission connection through the sprockets 13 and the transmission chain, thereby driving each roller 8 to rotate. The above-mentioned driving chain and transmission chain are not shown in the drawings. The non-powered transmission line 1 is relatively short. After the air-conditioning unit 5 is placed on it by the lifting trolley, it can be moved to the connecting transmission line 2 after a short-distance push. Therefore, the non-powered transmission line 1 does not need to be provided with a power device, and the rollers 8 on it can rotate, and it is not necessary to provide sprockets 13 for transmission.

[0036] In this embodiment, the power device further includes a chain tensioning mechanism 18. The chain tensioning mechanism 18 is used to adjust the tension of the transmission chain. The chain tensioning mechanism 18 is a common chain tensioner on the market, including a telescopic cylinder and a sprocket rotatably installed at its piston end. Among them, the sprocket is in transmission cooperation with the transmission chain. By adjusting the extension length of the telescopic cylinder, the tension degree of the transmission chain can be adjusted.

[0037] As Figure 3 , 4 shown, in this embodiment, a cylinder stop mechanism 12 is further arranged on the connecting transmission line 202. The cylinder stop mechanism 12 is used to stop the air-conditioning unit 5 when it is conveyed from the non-powered transmission line 1 to the connecting transmission line 202, so as to prevent the air-conditioning unit 5 from moving forward due to inertia during the lifting process through the lifting platform 201. The cylinder stop mechanism 12 includes a lifting cylinder 121, a rotating stop block 122, a mounting frame 123 and a roller 124. The middle part of the rotating stop block 122 is rotatably connected to the mounting frame 123 through a rotating shaft. The end of the piston rod of the lifting cylinder 121 is fixedly connected to the bottom of one end of the rotating stop block 122. The roller 124 is installed at the other end of the rotating stop block 122. When the air-conditioning unit 5 moves to the corresponding position, the lifting cylinder 121 rises, and the rotating stop block 122 rises to stop the guide bar 4. Then, the lifting platform 201 rises or falls, the lifting cylinder 121 retracts, and the rotating stop block 122 rotates relative to the mounting frame 123, causing the roller 124 to rise. At this time, the roller 124 is flush with the roller 8, allowing the guide bar 4 to pass through.

[0038] In this embodiment, the motor 14 is fixed to the ground through the motor mounting plate 16. A power socket 17 is provided on the side surface or other positions of the guard plate 6, and the power socket 17 is used to supply power to the motor 14.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
