Description

Technical Field

[0001] This utility model relates to the field of urban rail ventilation technology, specifically an adjustable ventilation support device for urban rail vehicle manufacturing. Background Technology

[0002] Urban rail ventilation ducts are mainly used for ventilation and air conditioning in urban rail transit systems such as subways. As a channel for air supply and exhaust, they can effectively control the temperature, humidity and air quality inside the subway, providing passengers with a comfortable riding environment, while also ensuring the normal operation and safety of subway facilities.

[0003] Existing urban rail ventilation duct support devices generally adopt external support methods. This support structure mainly relies on the external wall or bracket of the ventilation duct. Although it can bear the weight of the ventilation duct itself and external loads to a certain extent, due to the limited internal space and complex structure of the ventilation duct, it is difficult to implement effective internal support. This limitation can easily lead to the risk of local collapse of the ventilation duct during long-term use or under special working conditions, thereby affecting the ventilation effect and operational safety of the urban rail system. To this end, we propose an adjustable ventilation duct support device for urban rail vehicle manufacturing. Utility Model Content

[0004] One of the technical problems this application aims to solve is that it is difficult to implement effective internal support for the internal space of the air duct, which can easily lead to the risk of local collapse of the air duct during long-term use or when encountering special working conditions.

[0005] To address the aforementioned technical problems, this application provides an adjustable air duct support device for urban rail vehicle manufacturing, comprising a pipe and further including:

[0006] An outer support plate is provided on the outside of the pipe;

[0007] An internal support unit is disposed inside the pipe and is used to provide internal support for the pipe.

[0008] The internal support unit includes a support member disposed inside the pipe for supporting the inside of the pipe. One end of the support member is provided with a driving member for driving the support member to expand.

[0009] In some embodiments, the support includes a shaft disposed within a pipe, one end of which has a slot, and an outer ring is disposed around the shaft. A first rotating joint is disposed outside the ring, and a rotating rod is rotatably connected to the first rotating joint. A second rotating joint is rotatably connected to the top of the rotating rod, and a support rod is disposed at the top of the second rotating joint. An auxiliary rod is rotatably connected to the shaft, and a sliding sleeve is rotatably connected to the top of the auxiliary rod, the sliding sleeve being sleeved around the rotating rod.

[0010] In some embodiments, the first rotating joint, the rotating rod, the second rotating joint, the support rod, the auxiliary rod, and the sliding sleeve are arranged in four groups, all of which are arranged around the central axis of the shaft.

[0011] In some embodiments, the drive member includes a frame plate disposed outside the shaft body, the frame plate being L-shaped, a first toothed plate being slidably inserted inside the frame plate, the end of the first toothed plate being welded to a ring body, a second toothed plate being slidably inserted at the top of the frame plate, the second toothed plate being perpendicular to the first toothed plate, and a gear being rotatably connected to one side of the frame plate, the gear meshing with the first toothed plate and the second toothed plate.

[0012] In some embodiments, a fixing plate is provided inside the pipe, and a plurality of fixing rods are provided at the bottom of the fixing plate. A fixing unit is provided inside the pipe to drive the fixing plate and fixing rods to move, thereby inserting and fixing the two frame plates.

[0013] In some embodiments, the fixing unit includes a fixing plate disposed inside the pipe, the bottom of the fixing plate abutting against the top of the second toothed plate, a plurality of fixing rods being disposed at the bottom of the fixing plate, each of the plurality of fixing rods being inserted into a frame plate, an extension rod being disposed at the top of the fixing plate, the pipe being slotted, a limiting plate being disposed outside the pipe, a screw being threaded into the limiting plate, and the end of the screw contacting the extension rod.

[0014] In some embodiments, the pipe and the inner support unit are configured as two sets, which are arranged opposite to each other, with their two shafts abutting each other and their two frame plates abutting each other. The fixing rods in the fixing unit are configured as two sets, and the two sets of fixing rods are respectively inserted into the two frame plates. The two limiting plates outside the pipe are stacked in sequence, and the screw is inserted into the two limiting plates in sequence.

[0015] This utility model has at least the following beneficial effects:

[0016] Two internal support units are placed into the two pipes respectively. The second toothed plate is manually pushed to move. The second toothed plate drives the gear to rotate, and the gear drives the first toothed plate to move. The second toothed plate drives the ring to slide outside the shaft. The ring then drives the first rotating joint to move. The first rotating joint drives the rotating rod to rotate. With the support of the auxiliary rod, the second rotating joint and the support rod are driven to expand outward, which can initially limit and support the inside of the pipe. Then, the two sets of pipes and internal support units are combined, and the two shafts are connected. Then, the two pipes are externally fixed by the outer support plate. Then, the two sets of internal support units are fixed together by the fixing unit. Similarly, the expansion degree of the two sets of support components is limited to prevent loosening. In short, the inside of the pipe, which is used as an air duct, can be supported to prevent the external support from being damaged and causing inward collapse after long-term use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] An adjustable air duct support device for urban rail vehicle manufacturing includes a pipe 1 (existing technology), which can be configured as multiple pipes 1, and two pipes 1 can be combined together. It also includes an outer support plate 2 and an inner support unit 3. The outer support plate 2 is disposed on the outside of the pipe 1; the inner support unit 3 is disposed inside the pipe 1 and is used to provide internal support for the pipe 1.

[0028] The inner support unit 3 includes a support member 31 disposed inside the pipe 1 for supporting the interior of the pipe 1;

[0029] The support member 31 includes a shaft 311 disposed inside the pipe 1. One end of the shaft 311 has a slot 312 to accommodate the lifting and lowering of the second toothed plate 323, while avoiding interference with the lifting and lowering of the fixing rod 402. The shaft 311 is fitted with an annular body 313. A first rotating joint 314 is disposed outside the annular body 313. A rotating rod 315 is rotatably connected to the first rotating joint 314. A second rotating joint 316 is rotatably connected to the top of the rotating rod 315. A support rod 317 is disposed at the top of the second rotating joint 316. An auxiliary rod 318 is rotatably connected to the outside of the shaft 311. A sliding sleeve 319 is rotatably connected to the top of the auxiliary rod 318. The sliding sleeve 319 is fitted outside the rotating rod 315. The first rotating joint 314, the rotating rod 315, the second rotating joint 316, the support rod 317, the auxiliary rod 318, and the sliding sleeve 319 are arranged in four groups, all of which are arranged around the central axis of the shaft 311.

[0030] A drive member 32 is provided at one end of the support member 31 for driving the support member 31 to expand. The drive member 32 includes a frame plate 321 disposed outside the shaft 311. The frame plate 321 is L-shaped. A first toothed plate 322 is slidably inserted inside the frame plate 321. The end of the first toothed plate 322 is welded to the ring body 313. A second toothed plate 323 is slidably inserted at the top of the frame plate 321. The second toothed plate 323 is perpendicular to the first toothed plate 322. A gear 324 is rotatably connected to one side of the frame plate 321. The gear 324 meshes with the first toothed plate 322 and the second toothed plate 323. The first toothed plate 322 and the second toothed plate 323 do not interfere with each other.

[0031] Two inner support units 3 are placed into the two pipes 1 respectively. The second toothed plate 323 is manually pushed to move. The second toothed plate 323 drives the gear 324 to rotate. The gear 324 randomly drives the first toothed plate 322 to move. The second toothed plate 323 drives the ring body 313 to slide outside the shaft body 311. The ring body 313 then drives the first rotating joint 314 to move. The first rotating joint 314 drives the rotating rod 315 to rotate. With the support of the auxiliary rod 318, the second rotating joint 316 and the support rod 317 are driven to expand outward, which can initially limit and support the inside of the pipe 1. Then, the two sets of pipes 1 and inner support units 3 are combined, and the two shaft bodies 311 are connected. Then, the two pipes 1 are externally fixed by the outer support plate 2. Then, the two sets of inner support units 3 are fixed together by the fixing unit 4. Similarly, the expansion degree of the two sets of support members 31 is limited to prevent loosening. At this time, the inner support unit 3 can support the inside of the pipe 1 and prevent the pipe 1 from collapsing inward.

[0032] Example 2

[0033] Please see Figures 2-6This utility model provides a technical solution:

[0034] In Example 2, a fixing unit 4 is added inside the pipe 1, and a fixing plate 401 is provided inside the pipe 1. Multiple fixing rods 402 are provided at the bottom of the fixing plate 401. The fixing unit 4 is provided inside the pipe 1 to drive the fixing plate 401 and the fixing rods 402 to move, thereby inserting and fixing the two frame plates 321.

[0035] The fixing unit 4 includes a fixing plate 401 disposed inside the pipe 1. The bottom of the fixing plate 401 abuts against the top of the second toothed plate 323. Multiple fixing rods 402 are provided at the bottom of the fixing plate 401, and all of the fixing rods 402 are inserted into the frame plate 321. An extension rod 403 is provided at the top of the fixing plate 401. The pipe 1 is slotted, and a limiting plate 404 is provided outside the pipe 1. A screw 405 is threaded into the limiting plate 404. The end of the screw 405 contacts the extension rod 403. It should be noted that in order for two limiting plates 404 of the same specification to be inserted by the screw 405 at the same time, the two limiting plates 404 must be stacked. A pad is added to the bottom of one of the limiting plates 404 to facilitate stacking. The pad is existing technology and will not be described in detail here.

[0036] Pipe 1 and inner support unit 3 are set in two groups, which are arranged opposite to each other. The two shafts 311 abut against each other, and the two frame plates 321 abut against each other. The fixing rods 402 inside the fixing unit 4 are set in two groups, and the two groups of fixing rods 402 are respectively inserted into the two frame plates 321. The limiting plates 404 outside the two pipes 1 are stacked in sequence, and the screws 405 are inserted into the two limiting plates 404 in sequence.

[0037] After the two pipes 1 and the inner support unit 3 are combined, the two limiting plates 404 are disassembled. Then, using the existing clamping tools, the extension rod 403 is clamped and the fixing plate 401 is inserted into the two pipes 1 from the outside. The two sets of fixing rods 402 are inserted into the two frame plates 321 respectively. Then, the two limiting plates 404 are reinstalled. Then, the screw 405 is inserted into the two stacked limiting plates 404, rotated and screwed in, pressing against the extension rod 403, pushing the fixing plate 401 and the fixing rod 402, which can fix the two frame plates 321 together, that is, fix the two inner support units 3. At the same time, the fixing plate 401 is pushed, which will push the two second toothed plates 323 to move. The two second toothed plates 323 will then drive the two first toothed plates 322 to move, thereby limiting the expansion degree of the two support members 31 and preventing the internal support from loosening. At the same time, the expansion degree can be adjusted according to the different inner diameters of the pipes 1 to adapt to pipes 1 of different sizes.
