Description

Technical Field

[0001] This invention relates to the technical field of assembly line transfer, and specifically to a transfer trolley. Background Technology

[0002] In the refrigeration industry, the production and processing of components are becoming increasingly automated. The tube-to-tube sheet expansion of shell-and-tube heat exchangers is gradually shifting from traditional manual expansion to more efficient and stable robotic expansion. However, the processing of shell-and-tube heat exchangers requires tube storage, tube insertion, tube-to-tube sheet expansion, and inner core transfer, thus necessitating a transfer device for a production line that can work in conjunction with robotic tube expansion.

[0003] In the existing technology, for operations such as tube insertion and tube expansion in shell and tube heat exchangers, the inner core assembly generally needs to be placed horizontally to facilitate tube insertion and tube expansion operations. However, transporting the inner core assembly horizontally directly requires a large area during transportation, making transportation extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a transfer trolley to solve the technical problem in the prior art that the transfer of core components requires horizontal transportation, which occupies a large area and is extremely inconvenient.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a transfer trolley is provided, comprising: a support and fixing component for fixing an inner core component, a moving component for moving the support component, and a rotating component for rotating the support and fixing component. The rotating component is disposed between the support and fixing component and the moving component, the rotating component is fixedly connected to the support and fixing component, and the rotating component is rotatably connected to the moving component.

[0006] Furthermore, the support and fixing assembly includes a positioning plate for fixing the inner core assembly and a support plate for supporting the inner core assembly, the support plate being perpendicular to the positioning plate.

[0007] Furthermore, the support fixing assembly also includes a support adjustment mechanism for adjusting the position of the support plate.

[0008] Furthermore, the support adjustment mechanism includes a fixed plate fixedly connected to the positioning plate and a height adjustment rod fixedly connected to the support plate, wherein the height adjustment rod is slidably fixedly connected to the fixed plate.

[0011] Furthermore, the positioning plate and / or the limiting ring are provided with positioning protrusions, and the limiting ring or the inner core assembly has a groove on its tube plate that cooperates with the positioning protrusions.

[0012] Furthermore, the rotating assembly includes: a first fixed support rod fixedly connected to the supporting and fixing assembly; a second fixed support rod fixedly connected to the moving assembly; a rotating shaft connecting the first fixed support rod and the second fixed support rod respectively, the rotating shaft being fixedly connected to the first fixed support rod and rotatably connected to the second fixed support rod; and a driving mechanism disposed at the shaft end of the rotating shaft and capable of driving the rotating shaft to rotate.

[0013] Furthermore, the drive mechanism includes a rotary drive member and a reducer disposed on the output shaft of the rotary drive member.

[0014] Furthermore, the moving component includes a base plate, a sliding plate disposed on the base plate, and a roller disposed at the bottom of the base plate. The rotating component is fixed to the sliding plate, the sliding plate is slidably connected to the base plate, and the moving direction of the sliding plate is perpendicular to the moving direction of the roller.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Please refer to the following: Figure 1 and Figure 2 The transfer trolley provided by the present invention will now be described. The transfer trolley includes a support and fixing component 2 for fixing the inner core component 1, a moving component 3 for moving the support component, and a rotating component 4 for rotating the support and fixing component 2. The rotating component 4 is disposed between the support and fixing component 2 and the moving component 3. The rotating component 4 is fixedly connected to the support and fixing component 2 and rotatably connected to the moving component 3.

[0029] Compared with the prior art, the transfer trolley provided by this invention has the following advantages: the moving component 3 enables the movement of the entire transfer trolley; the supporting and fixing component 2 supports and fixes the inner core component 1, thereby ensuring the stability of the inner core component 1; and the rotating component 4 drives the rotation of the inner core component 1 and the supporting and fixing component 2. This allows the inner core component 1 to be placed horizontally during operations such as tube threading and tube expansion, and vertically during transportation. This facilitates the transportation of the inner core component 1 and the performance of operations such as tube threading and tube expansion, and is simple to use.

[0030] Specifically, the moving component 3 can drive or propel the entire transfer trolley to move. The moving component 3 can be a structure such as rollers 33 or a conveyor belt structure. The supporting and fixing component 2 can support and fix the inner core component 1, thereby ensuring the stability of the entire inner core component 1 in both vertical and horizontal states. The supporting and fixing component 2 can be a sleeve directly fitted onto the outside of the inner core component 1 to fix the inner core component 1, or a plate not fixed to one side of the inner core component 1, through a fixed connection between the plate and the inner core component 1 to achieve a fixed connection of the inner core component 1. The rotating component 4 can drive the rotation of the supporting and fixing component 2. Its rotation can be driven by a rotating drive component 431 such as a motor or a motor to drive the rotation of the supporting and fixing component 2, or it can be manually adjusted to adjust the position of the supporting and fixing component 2.

[0031] Furthermore, please refer to the following: Figures 3 to 5As a specific embodiment of the transfer trolley provided by the present invention, the support and fixing assembly 2 includes a positioning plate 21 for fixing the inner core assembly 1 and a support plate 22 for supporting the inner core assembly 1, wherein the support plate 22 is perpendicular to the positioning plate 21. Specifically, the inner core assembly 1 includes a tube plate 11 at the bottom of the inner core assembly 1 and a side of the inner core assembly 1. The positioning plate 21 is fixedly connected to the tube plate 11 at the bottom of the inner core assembly 1, and the support plate 22 can support the side of the inner core assembly 1, thereby ensuring the stability of the inner core assembly 1 at two angles.

[0032] When the inner core assembly 1 is placed horizontally, the support plate 22 is located at the bottom of the inner core assembly 1, and the positioning plate 21 is located on the side of the inner core assembly 1; when the inner core assembly 1 is placed vertically, the support plate 22 is located on the side of the inner core assembly 1, and the positioning plate 21 is located at the bottom of the inner core assembly 1. That is, whether the inner core assembly 1 is placed horizontally or vertically, there is always a plate that can support the inner core assembly 1.

[0033] Furthermore, please refer to the following: Figures 3 to 5 As a specific embodiment of the transfer trolley provided by the present invention, the support fixing assembly 2 further includes a support adjustment mechanism 23 for adjusting the position of the support plate 22. Specifically, shell-and-tube heat exchangers generally have multiple specifications, and the corresponding dimensions of the inner core assembly 1 also change accordingly. The support adjustment mechanism 23 can adjust the position of the support plate 22, that is, adjust the position of the support plate 22 relative to the inner core assembly 1, thereby ensuring that the support plate 22 is always in contact with the inner core assembly 1, ensuring stable support for the inner core assembly 1. The support plate 22 can be directly fixed to the positioning plate 21, and the support adjustment mechanism 23 is a sliding mechanism that controls the sliding of the support plate 22 on the fixed positioning plate 21; the support plate 22 can also not be in direct contact with the positioning plate 21, and the support plate 22 can be adjusted by a support rod or other mechanism, which is not limited here.

[0034] Furthermore, please refer to the following: Figures 3 to 5 As a specific embodiment of the transfer trolley provided by the present invention, the support adjustment mechanism 23 includes a fixed plate 231 fixedly connected to the positioning plate 21 and a height adjustment rod 232 fixedly connected to the support plate 22, wherein the height adjustment rod 232 is slidably fixedly connected to the fixed plate 231.

[0035] Preferably, support rods 233 can also be provided on both sides of the height adjustment rod 232. The support rods 233 can be combined with the height adjustment rod 232 to support the support plate 22, thereby achieving the effect of stable support for the support rods 233.

[0036] Furthermore, please refer to the following: Figures 3 to 5As a specific embodiment of the transfer trolley provided by the present invention, the support adjustment mechanism 23 includes a fixed plate 231 fixedly connected to the positioning plate 21 and a height adjustment rod 232 fixedly connected to the support plate 22. The height adjustment rod 232 is slidably fixedly connected to the fixed plate 231. Specifically, the fixed plate 231 is used to connect with the positioning plate 21, the height adjustment rod 232 is slidably connected to the fixed plate 231, and the support plate 22 is disposed at the shaft end of the height adjustment rod 232. The support plate 22 can move up and down under the drive of the height adjustment rod 232. The height adjustment rod 232 is threaded, and the fixed plate 231 has a through hole for the height adjustment rod 232 to pass through. The height adjustment rod 232 can extend and retract relative to the fixed plate 231 when rotating, thus adjusting the height of the support plate 22. The rotation of the height adjustment rod 232 can be manually driven by the operator or driven by a motor or a motor drive component 431. Of course, depending on the actual situation and specific needs, in other embodiments of the present invention, the height adjustment rod 232 can also be a lifting rod such as a cylinder, hydraulic system or lead screw, with the fixed end of the lifting rod fixed to the positioning plate 21 and the movable end of the lifting rod fixedly connected to the support plate 22. This is not a unique limitation.

[0037] Furthermore, please refer to the following: Figures 3 to 5 As a specific embodiment of the transfer trolley provided by the present invention, the positioning plate 21 is provided with a stepped hole 211 for installing the inner core component 1, and the tube plate 11 of the inner core component 1 is fixed in the stepped hole 211. Specifically, the stepped hole 211 provides a through hole on the positioning plate 21, and a step is formed in the through hole. Several fixing holes 321 are provided on the step, and several fixing holes 321 are also provided at corresponding positions on the tube plate 11 of the inner core component 1. The tube plate 11 can be fixed on the step, thereby fixing the tube plate 11 of the inner core component 1. At the same time, the inner edge of the stepped hole 211 can limit and fix the outer wall of the inner core component 1, which can effectively ensure the stability of the positioning plate 21 and the inner core component 1.

[0038] Further, see Figures 3 to 5In one specific embodiment of the transfer trolley provided by the present invention, a limiting ring 212 is fixed inside the stepped hole 211, and the tube plate 11 of the inner core component 1 is fixed inside the limiting ring 212. Specifically, the limiting ring 212 is set on the step of the stepped hole 211, and the limiting ring 212 and the step inside the stepped hole 211 are fixedly connected. A stepped hole (not shown in the figure) is also formed on the inner side of the limiting ring 212, and the tube plate 11 of the inner core component 1 can be fixed on the step of the stepped hole, thereby fixing the tube plate 11 of the inner core component 1. At this time, through the conversion of the limiting ring 212, the positioning plate 21 can fix inner core components 1 of different specifications. It is only necessary to adjust the size of the limiting ring 212 or not set the limiting ring 212, so that the transfer trolley can have better applicability.

[0039] Preferably, a snap-fit ​​structure 214 is provided on the positioning plate 21. The snap-fit ​​structure 214 includes a rotating shaft and a snap-fit ​​plate. The rotating shaft and the snap-fit ​​plate are fixedly connected. The rotating shaft is inserted into the positioning plate 21 and rotatably connected to the positioning plate 21. The snap-fit ​​plate can be snapped onto the upper surface of the limiting ring 212 and the tube plate 11, thereby strengthening the fixation of the tube plate 11 of the inner core assembly 1 and ensuring the stability of the entire inner core assembly 1.

[0040] Further, please refer to Figures 3 to 5 As a specific embodiment of the transfer trolley provided by the present invention, the positioning plate 21 and / or the limiting ring 212 are provided with positioning protrusions 213, and the limiting ring 212 or the tube plate 11 of the inner core assembly 1 is provided with grooves that cooperate with the positioning protrusions 213. Specifically, the positioning protrusion 213 can be located directly inside the stepped hole 211 of the positioning plate 21 or inside the limiting ring 212. The tube plate 11 of the inner core assembly 1 or the limiting ring 212 can be provided with a groove that matches the positioning protrusion 213. The limiting ring 212 can be set according to the size of the inner core assembly 1. In this case, the positioning protrusion 213 on the inner side of the positioning plate 21 engages with the groove on the outer side of the limiting ring 212. The positioning protrusion 213 on the inner side of the limiting ring 212 engages with the groove on the tube plate 11 of the inner core assembly 1. Alternatively, the limiting ring 212 can be omitted according to the size of the inner core assembly 1. In this case, the positioning protrusion 213 on the inner side of the positioning plate 21 directly engages with the groove on the tube plate 11 of the inner core assembly 1.

[0041] Preferably, the positioning protrusion 213 can be directly set inside the stepped hole 211 of the positioning plate 21 or inside the limiting ring 212. The positioning protrusion 213 can also be set on a plate, and the outer side of the stepped hole 211 or the outer side of the limiting ring 212 is provided with a groove for accommodating the plate. The groove is connected to the internal through hole of the stepped hole 211 or the limiting ring 212. The positioning protrusion 213 can be inserted into the stepped hole 211 or the internal through hole of the limiting ring 212.

[0042] Preferably, the number of positioning protrusions 213 on the positioning plate 21 and the limiting ring 212 can both be two, and the two positioning protrusions 213 are arranged opposite to each other. This can play a better limiting and positioning role, and can effectively avoid the problem of inaccurate positioning during pipe installation, which would cause damage to the pipe.

[0043] Further, please refer to Figure 1 and Figure 2 As a specific embodiment of the transfer trolley provided by the present invention, the rotating component 4 includes: a first fixed support rod 41 fixedly connected to the support and fixing component 2; a second fixed support rod 42 fixedly connected to the moving component 3; a rotating shaft (not shown) connecting the first fixed support rod 41 and the second fixed support rod 42 respectively, the rotating shaft being fixedly connected to the first fixed support rod 41 and rotatably connected to the second fixed support rod 42; and a driving mechanism 43 disposed at the shaft end of the rotating shaft and capable of driving the rotating shaft to rotate. Specifically, the rotating component 4 can drive the supporting and fixed component 2 to rotate relative to the moving component 3, thereby allowing the inner core component 1 to be set horizontally or vertically. The first fixed support rod 41 can be connected to the entire supporting and fixed component 2, and the second fixed support rod 42 can be fixedly connected to the moving component 3, thereby serving to connect the supporting and fixed component 2 and the moving component 3. The first fixed support rod 41 and the second fixed support rod 42 can be rotated relative to each other through a rotating shaft. The rotating shaft can rotate under the drive of the driving mechanism 43, which is fixed to the second fixed support rod 42. The rotating shaft and the first fixed support rod 41 are fixedly connected, thereby driving the rotation of the first fixed support rod 41. A bearing can be installed at the connection between the rotating shaft and the second fixed support rod 42 to avoid wear on the second fixed support rod 42 caused by the rotating shaft.

[0044] Further, please refer to Figure 1 and Figure 2 As a specific embodiment of the transfer trolley provided by the present invention, the drive mechanism 43 includes a rotation drive component 431 and a reducer 432 disposed on the output shaft of the rotation drive component 431. Specifically, the drive component 431 can be a manually driven turntable or a motor, etc. The reducer 432 can reduce the rotation speed of the drive component 431, thereby preventing the first fixed support rod 41 from rotating too fast, which would cause the entire support and fixing assembly 2 to rotate too fast and affect the fixation of the inner core assembly 1. The reducer 432 is generally a worm gear reducer 432, which has a good reverse self-locking function and can have a large reduction ratio.

[0045] Further, please refer to Figure 1 and Figure 2As a specific embodiment of the transfer trolley provided by the present invention, the moving component 3 includes a base plate 31, a sliding plate 32 disposed on the base plate 31, and a roller 33 disposed at the bottom of the base plate 31. The rotating component 4 is fixed on the sliding plate 32. The sliding plate 32 is slidably connected to the base plate 31, and the moving direction of the sliding plate 32 is perpendicular to the moving direction of the roller 33. Specifically, the roller 33 is located at the bottom of the base plate 31 and can drive the base plate 31 to move. The sliding plate 32 can move relative to the upper surface of the base plate 31, and the sliding direction of the sliding plate 32 is not consistent with the moving direction of the base plate 31. At this time, the sliding plate 32 can combine with the base plate 31 to achieve better adjustment of various angles, thereby enabling position adjustment when the transfer trolley is moved to the tube expansion device or tube insertion device.

[0046] Preferably, please refer to Figure 1 and Figure 2 The upper surface of the base plate 31 is provided with a guide rail 34, and the bottom of the sliding plate 32 is provided with a groove that cooperates with the guide rail 34, so that the sliding plate 32 can slide relative to the base plate 31. Generally, there are two guide rails 34 and two grooves, respectively located on opposite sides of the base plate 31 or the sliding plate 32, to achieve a stable support effect. Several fixing blocks 35 are also provided between the two guide rails 34, each with a fixing hole 321. The sliding plate 32 also has several fixing holes 321, which can cooperate with the fixing holes 321 on any of the fixing blocks 35 to achieve a fixed position. Of course, depending on the actual situation and specific needs, in other embodiments of the present invention, a groove can also be provided on the base plate 31, and a guide rail 34 can be provided on the bottom of the sliding plate 32; this is not a unique limitation.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
