DETAILED DESCRIPTION

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] Example 1

[0037] An embodiment of the present invention provides a heat exchanger assembly device, comprising:

[0038] Ground rail assembly 3;

[0039] A first support assembly 1 is provided on the ground rail assembly 3 and is used to carry a first assembly member; and

[0040] The second support assembly 2 is movably provided on the ground rail assembly 3 and is used to carry the second assembly part. The second support assembly 2 can move along the ground rail assembly 3 to drive the second assembly part to be docked and assembled with the first assembly part.

[0041] The second support assembly 2 includes an active support seat 21 , a driven support seat 22 and a clutch mechanism 23 connecting the two support seats. The clutch mechanism 23 is used to control the transmission from the active support seat 21 to the driven support seat 22 .

[0042] Specifically, the heat exchanger assembly device of the present invention is primarily designed for the butt-jointed assembly of heat exchanger tube bundles and the heat exchanger shell, a process that presents a relatively high degree of assembly difficulty. This reduces the difficulty of assembling the heat exchanger tube bundle and the shell. Of course, this does not represent the full scope of the assembly device's applicability; it can also be applied to other components requiring butt-jointed assembly.

[0043] Take the assembly between the heat exchange tube bundle and the shell as an example, as shown in the attached figure Figure 4 As shown, first place the shell on the first support assembly 1, and place the heat exchange tube bundle on the second support assembly 2. Then, the clutch mechanism 23 is used to connect the active support seat 21 and the driven support seat 22 of the second support assembly 2. Then, the active support seat 21 drives the driven support seat 22, thereby driving the heat exchange tube bundle toward the side of the shell. At this time, the first support assembly 1 and the shell remain stationary. After moving to the appropriate predetermined position (before the tube bundle is docked into the shell), the clutch mechanism 23 is used to disconnect the active support seat 21 and the driven support seat 22. At this time, the driven assembly remains stationary and maintains support for the tube bundle. The active support seat 21 moves alone to push the heat exchange tube bundle to dock and insert into the shell. After the heat exchange tube bundle is fully inserted into place, the active support seat 21 and the driven support seat 22 move to reset.

[0044] Of course, the above content and the assembly process are merely exemplary descriptions, and the actual heat exchange tube bundle can also be placed on the first support assembly 1 .

[0045] The assembly device of the present invention, through the design of a floor rail assembly and two support assemblies installed on the floor rail assembly, can respectively support two assembly parts that need to be docked and assembled. The corresponding support assemblies can also drive the assembly parts to move along the floor rail assembly and push the two assembly parts to be docked and assembled, eliminating most of the manual labor of personnel while maintaining the accuracy and assembly quality of the docking assembly.

[0046] Preferably, the driven support seat 22 is arranged between the active support seat 21 and the first support assembly 1; a proximity switch 4 is arranged between the driven support seat 22 and the active support seat 21, and the proximity switch 4 is arranged on the driven support seat 22 and / or the active support seat 21, and is located on the side where the two are close to each other; a proximity switch 4 is arranged between the driven support seat 22 and the first support assembly 1, and the proximity switch 4 is arranged on the driven support seat 22 and / or the first support assembly 1, and is located on the side where the two are close to each other.

[0047] Specifically, as shown in the accompanying drawings Figure 1 As shown, the relative positions of the active support seat 21 and the driven support seat 22 are further designed, and the driven support seat 22 is closer to the support seat of the first support assembly 1. In this way, when the assembly parts are docked, the rear end of the assembly parts is pushed, while the front end can be continuously and stably supported, making the entire docking and assembly process smoother.

[0048] In addition, combined with the design of the proximity switch 4, the distance between the driven support seat 22 and the support seat of the first support assembly 1 can be detected by the proximity switch 4. This distance is the position at which the clutch mechanism 23 needs to disconnect the connection between the active support seat 21 and the driven support seat 22. Therefore, after the front driven support seat 22 is driven to the arrival position, the clutch mechanism 23 is disconnected, the driven support seat 22 remains stationary, and at the same time, the lifting member 6 and the guide column 7 on the driven support seat 22 will drop to the lowest position and disengage from the corresponding assembly parts. After the driven support seat 22 remains stationary, the proximity switch 4 can continuously detect the distance between the driven support seat 22 and the support seat of the first support assembly 1. Once the distance changes, it indicates that the driven support seat 22 or the support seat of the first support assembly 1 has unexpectedly moved, so that timely inspection and adjustment can be carried out to avoid unexpected movement affecting the docking assembly.

[0049] In addition, the distance between the support bases of the driven support base 22 and the active support base 21 can also be detected by the proximity switch 4. After the driven support base 22 stops, the active support base 21 continues to drive the assembly parts thereon to dock with the assembly parts on the first support assembly 1, and then the distance between the active support base 21 and the driven support base 22 continues to decrease. After the proximity switch 4 detects that the distance between the active support base 21 and the driven support base 22 is reduced to a corresponding value, it indicates that the active support base 21 has moved into place. At this time, the active support base 21 stops moving, and the lifting member 6 and the guide column 7 thereon will drop to the lowest position.

[0050] Furthermore, the first support assembly 1 and / or the second support assembly 2 has a support bracket 5 for carrying corresponding assembly parts, and the corresponding support assembly is provided with a lifting member 6 connected to the support bracket 5 to lift and adjust the carrying height of the support bracket 5.

[0051] Specifically, since the assembly accuracy needs to be ensured, the heights of the two assembly parts on the corresponding support components must be aligned, which is achieved by the support bracket 5 provided on the support component. Figure 1 As shown, in this embodiment, a bearing support 5 is provided on the second supporting assembly 2 , and the second supporting assembly 2 also has a lifting member 6 for controlling the lifting of the bearing support 5 . In this embodiment, the lifting member 6 is a lifting cylinder.

[0052] Taking the assembly of the heat exchange tube bundle and the shell as an example, the shell is placed on the first support assembly 1, and the heat exchange tube bundle is then placed on the second support assembly 2. The lifting member 6 then drives the support 5 to rise and fall, adjusting the height of the heat exchange tube bundle so that the heat exchange tube bundle is aligned with the inner cavity of the shell. Furthermore, the alignment of the two assembly components can be adjusted in real time throughout the assembly process.

[0053] In addition, based on the fact that the second support assembly 2 includes an active support seat 21 and a driven support seat 22, a bearing support 5 structure is set on both support seats, and in order to ensure that the lifting heights of the bearing supports 5 on the two support seats are consistent and avoid the tilting of the heat exchange tube bundle due to inconsistent lifting heights, the lifting parts 6 on the two bearing supports 5 adopt linkage control to maintain the consistency of the lifting action and amplitude.

[0054] Furthermore, the support 5 includes a base 52 and a support body 51 disposed on the base 52 , a fine-tuning component 53 is disposed on the base 52 , and the support body 51 is mounted on the fine-tuning component 53 ;

[0055] The fine-tuning assembly 53 is used to adjust the position of the support body 51 in a horizontal plane direction perpendicular to the track direction of the ground rail assembly 3 .

[0056] Specifically, as shown in the accompanying drawings Figure 2As shown, in addition to being able to adjust the placement height of the corresponding assembly parts, in order to further maintain the accuracy of the docking assembly, the support bracket 5 also needs to be able to adjust the position of the assembly parts in the horizontal left and right directions, that is, the direction orthogonal to the track direction of the ground rail assembly 3, and thus the structure of the support bracket 5 needs to be further designed.

[0057] In this embodiment, the base 52 of the support bracket 5 is fixed to the top of the support base of the second support assembly 2. A fine-tuning assembly 53 is provided on the base 52. In this embodiment, the fine-tuning assembly 53 adopts a screw-guide mechanism. The screw of the screw-guide mechanism is perpendicular to the track direction of the ground rail assembly 3. The support body 51 of the support bracket 5 is fixedly connected to the slider of the screw-guide mechanism. The horizontal position of the support body 51 can be adjusted by rotating the screw by the handle at the end of the screw.

[0058] Preferably, a plurality of guide posts 7 extending along the lifting direction are further provided on the corresponding support assembly, and one end of the guide post 7 is fixedly connected to the supporting bracket 5 and can move synchronously with the supporting bracket 5 .

[0059] Specifically, as shown in the accompanying drawings Figure 1 and Figure 2 As shown, in this embodiment, guide posts 7 are provided at four locations, one each located around the support base of the second support assembly 2 and slidingly engaging with the sleeve on the support base. The top of the guide posts 7 are fixedly connected to the bottom of the support bracket 5 (base 52) around the periphery, thereby increasing the number of sliding engagement structures between the support bracket 5 and the support base, and providing a guiding function for the lifting and lowering of the support bracket 5.

[0060] Preferably, the first support assembly 1 and the second support assembly 2 both have a V-shaped bracket 8, and the bracket 8 is used to limit the corresponding assembly parts;

[0061] For the support assembly provided with the supporting bracket 5 , the bracket 8 is constructed on the corresponding supporting bracket 5 .

[0062] Specifically, as shown in the accompanying drawings Figure 1 As shown, this embodiment provides a V-shaped bracket 8 for the cylindrical heat exchange tube bundle and housing. Bracket 8 serves to limit the heat exchange tube bundle or housing placed therein, improving placement stability. Furthermore, the slope of the V-shaped bracket 8 automatically returns to its center position due to the gravity of the corresponding heat exchange tube bundle or housing, facilitating control of alignment accuracy.

[0063] Furthermore, the floor rail assembly 3 includes a rack 31 , and an active motor 211 is provided on the active support seat 21 . The active motor 211 cooperates with the rack 31 through a gear 212 to drive the active support seat 21 to move along the floor rail assembly 3 .

[0064] Specifically, as shown in the accompanying drawings Figure 1 and Figure 2 As shown, the ground rail assembly 3 primarily provides a foundation for the movement and installation of the support assembly. The ground rail assembly 3 primarily comprises two parallel tracks and a rack 31 parallel to the tracks. The rack 31 is used to cooperate with the active support base 21 of the second support assembly 2 to achieve active movement of the active support base 21 along the tracks. The active support base 21 is provided with an active motor 211. The output shaft of the active motor 211 faces and is mounted with a gear 212. The gear 212 meshes with the rack 31, achieving movement along the tracks guided by the rack 31.

[0065] Furthermore, the first support assembly 1 includes a first support seat 11 and a second support seat 12 movably arranged on the ground rail assembly 3, and the first support seat 11 and / or the second support seat 12 have a positioning member, which is used to fix the position of the corresponding support seat on the ground rail assembly 3.

[0066] Specifically, the first support seat 11 and the second support seat 12 of the first support assembly 1 are also structurally designed to be movable along the floor rail assembly 3, except that in the normal assembly state, their positions on the floor rail assembly 3 remain fixed. The movement of the support seat of the first support assembly 1 is used to accommodate assembly parts of different lengths. For example, if the length of the assembly part is long, the first support seat 11 and / or the second support seat 12 can be moved along the floor rail assembly 3 by contacting the limiting state between the positioning member and the floor rail assembly 3, thereby increasing the distance between the first support seat 11 and the second support seat 12, thereby accommodating the longer assembly part; conversely, the distance between the first support seat 11 and the second support seat 12 can be reduced by movement to accommodate the shorter assembly part.

[0067] In this embodiment, the positioning member can be a positioning bolt, which cooperates with different screw holes provided along the track of the ground rail assembly 3 to achieve positioning.

[0068] Example 2

[0069] This embodiment mainly further illustrates the structural design of the clutch mechanism 23 .

[0070] An embodiment of the present invention provides a heat exchanger assembly device, comprising:

[0071] Ground rail assembly 3;

[0072] A first support assembly 1 is provided on the ground rail assembly 3 and is used to carry a first assembly member; and

[0073] The second support assembly 2 is movably provided on the ground rail assembly 3 and is used to carry the second assembly part. The second support assembly 2 can move along the ground rail assembly 3 to drive the second assembly part to be docked and assembled with the first assembly part.

[0074] The second support assembly 2 includes an active support seat 21 , a driven support seat 22 and a clutch mechanism 23 connecting the two support seats. The clutch mechanism 23 is used to control the transmission from the active support seat 21 to the driven support seat 22 .

[0075] Specifically, the heat exchanger assembly device of the present invention is primarily designed for the butt-jointed assembly of heat exchanger tube bundles and the heat exchanger shell, a process that presents a relatively high degree of assembly difficulty. This reduces the difficulty of assembling the heat exchanger tube bundle and the shell. Of course, this does not represent the full scope of the assembly device's applicability; it can also be applied to other components requiring butt-jointed assembly.

[0076] Take the assembly between the heat exchange tube bundle and the shell as an example, as shown in the attached figure Figure 4 As shown, first place the shell on the first support assembly 1, and place the heat exchange tube bundle on the second support assembly 2. Then, the clutch mechanism 23 is used to connect the active support seat 21 and the driven support seat 22 of the second support assembly 2. Then, the active support seat 21 drives the driven support seat 22, thereby driving the heat exchange tube bundle toward the side of the shell. At this time, the first support assembly 1 and the shell remain stationary. After moving to the appropriate predetermined position (before the tube bundle is docked into the shell), the clutch mechanism 23 is used to disconnect the active support seat 21 and the driven support seat 22. At this time, the driven assembly remains stationary and maintains support for the tube bundle. The active support seat 21 moves alone to push the heat exchange tube bundle to dock and insert into the shell. After the heat exchange tube bundle is fully inserted into place, the active support seat 21 and the driven support seat 22 move to reset.

[0077] Of course, the above content and the assembly process are merely exemplary descriptions, and the actual heat exchange tube bundle can also be placed on the first support assembly 1 .

[0078] Furthermore, the clutch mechanism 23 includes a clutch rod 231, a first end of which is fixed to one of the support seats, and a second end of which is engaged in a slide groove 232 of the other support seat. The support seat where the slide groove 232 is located is provided with a pressing member 233 located above the slide groove 232;

[0079] The pressing member 233 can be moved to press and fix the second end of the clutch rod 231 to the bottom of the sliding groove 232 or to loosen the second end of the clutch rod 231 from the sliding groove 232 .

[0080] Specifically, as shown in the accompanying drawings Figure 2 and Figure 3As shown, the clutch mechanism 23 primarily utilizes friction to achieve connection between the active support base 21 and the passive support base 22. In this embodiment, the first end of the clutch rod 231 is fixed to the passive support base 22, and the second end of the clutch rod 231 is accommodated in a chute 232 of the active support base 21. The direction of the chute 232 is consistent with the direction of the track of the ground rail assembly 3. A pressing member 233 (a cylinder in this embodiment) is installed above the chute 232 of the active support base 21.

[0081] When the clutch mechanism 23 is locked, the pressing member 233 is pressed downward, pressing the clutch rod 231 against the chute 232. The friction between the bottom of the clutch rod 231 and the bottom of the chute 232 achieves the connection and relative fixation between the active support seat 21 and the driven support seat 22. When the clutch mechanism 23 is released, the pressing member 233 is retracted, the clutch rod 231 loses pressure, and the friction between it and the bottom of the chute 232 is very small, insufficient to achieve the relative fixation between the active support seat 21 and the driven support seat 22.

[0082] Preferably, the first end of the clutch rod 231 is hinged to the rotating seat 234 on the corresponding support seat.

[0083] Specifically, the rotating seat 234 enables the clutch rod 231 to flip. When the pressing member 233 compresses the second end of the clutch rod 231, it undergoes a certain amount of flipping motion in the vertical plane. If the first end of the clutch rod 231 were completely fixed at this time, stress would be generated within the clutch rod 231, which would be detrimental to the stability of the structure. Therefore, the hinged structure of the rotating seat 234 provides the clutch rod 231 with the freedom to flip in the vertical plane, thus avoiding the generation of stress. In addition, the clutch rod 231 can be flipped as needed to adjust its posture, adapting to the different structures and heights of the chute 232.

[0084] Preferably, the driven support seat 22 is arranged between the active support seat 21 and the first support assembly 1; a proximity switch 4 is arranged between the driven support seat 22 and the active support seat 21, and the proximity switch 4 is arranged on the driven support seat 22 and / or the active support seat 21, and is located on the side where the two are close to each other; a proximity switch 4 is arranged between the driven support seat 22 and the first support assembly 1, and the proximity switch 4 is arranged on the driven support seat 22 and / or the first support assembly 1, and is located on the side where the two are close to each other.

[0085] Specifically, as shown in the accompanying drawings Figure 1 As shown, the relative positions of the active support seat 21 and the driven support seat 22 are further designed, and the driven support seat 22 is closer to the support seat of the first support assembly 1. In this way, when the assembly parts are docked, the rear end of the assembly parts is pushed, while the front end can be continuously and stably supported, making the entire docking and assembly process smoother.

[0086] In addition, combined with the design of the proximity switch 4, the distance between the driven support seat 22 and the support seat of the first support assembly 1 can be detected by the proximity switch 4. This distance is the position at which the clutch mechanism 23 needs to disconnect the connection between the active support seat 21 and the driven support seat 22. Therefore, after the front driven support seat 22 is driven to the arrival position, the clutch mechanism 23 is disconnected, the driven support seat 22 remains stationary, and at the same time, the lifting member 6 and the guide column 7 on the driven support seat 22 will drop to the lowest position and disengage from the corresponding assembly parts. After the driven support seat 22 remains stationary, the proximity switch 4 can continuously detect the distance between the driven support seat 22 and the support seat of the first support assembly 1. Once the distance changes, it indicates that the driven support seat 22 or the support seat of the first support assembly 1 has unexpectedly moved, so that timely inspection and adjustment can be carried out to avoid unexpected movement affecting the docking assembly.

[0087] In addition, the distance between the support bases of the driven support base 22 and the active support base 21 can also be detected by the proximity switch 4. After the driven support base 22 stops, the active support base 21 continues to drive the assembly parts thereon to dock with the assembly parts on the first support assembly 1, and then the distance between the active support base 21 and the driven support base 22 continues to decrease. After the proximity switch 4 detects that the distance between the active support base 21 and the driven support base 22 is reduced to a corresponding value, it indicates that the active support base 21 has moved into place. At this time, the active support base 21 stops moving, and the lifting member 6 and the guide column 7 thereon will drop to the lowest position.

[0088] Furthermore, the first support assembly 1 and / or the second support assembly 2 has a support bracket 5 for carrying corresponding assembly parts, and the corresponding support assembly is provided with a lifting member 6 connected to the support bracket 5 to lift and adjust the carrying height of the support bracket 5.

[0089] Specifically, since the assembly accuracy needs to be ensured, the heights of the two assembly parts on the corresponding support components must be aligned, which is achieved by the support bracket 5 provided on the support component. Figure 1 As shown, in this embodiment, a bearing support 5 is provided on the second supporting assembly 2 , and the second supporting assembly 2 also has a lifting member 6 for controlling the lifting of the bearing support 5 . In this embodiment, the lifting member 6 is a lifting cylinder.

[0090] Taking the assembly of the heat exchange tube bundle and the shell as an example, the shell is placed on the first support assembly 1, and the heat exchange tube bundle is then placed on the second support assembly 2. The lifting member 6 then drives the support 5 to rise and fall, adjusting the height of the heat exchange tube bundle so that the heat exchange tube bundle is aligned with the inner cavity of the shell. Furthermore, the alignment of the two assembly components can be adjusted in real time throughout the assembly process.

[0091] In addition, based on the fact that the second support assembly 2 includes an active support seat 21 and a driven support seat 22, a bearing support 5 structure is set on both support seats, and in order to ensure that the lifting heights of the bearing supports 5 on the two support seats are consistent and avoid the tilting of the heat exchange tube bundle due to inconsistent lifting heights, the lifting parts 6 on the two bearing supports 5 adopt linkage control to maintain the consistency of the lifting action and amplitude.

[0092] Furthermore, the support 5 includes a base 52 and a support body 51 disposed on the base 52 , a fine-tuning component 53 is disposed on the base 52 , and the support body 51 is mounted on the fine-tuning component 53 ;

[0093] The fine-tuning assembly 53 is used to adjust the position of the support body 51 in a horizontal plane direction perpendicular to the track direction of the ground rail assembly 3 .

[0094] Specifically, as shown in the accompanying drawings Figure 2 As shown, in addition to being able to adjust the placement height of the corresponding assembly parts, in order to further maintain the accuracy of the docking assembly, the support bracket 5 also needs to be able to adjust the position of the assembly parts in the horizontal left and right directions, that is, the direction orthogonal to the track direction of the ground rail assembly 3, and thus the structure of the support bracket 5 needs to be further designed.

[0095] In this embodiment, the base 52 of the support bracket 5 is fixed to the top of the support base of the second support assembly 2. A fine-tuning assembly 53 is provided on the base 52. In this embodiment, the fine-tuning assembly 53 adopts a screw-guide mechanism. The screw of the screw-guide mechanism is perpendicular to the track direction of the ground rail assembly 3. The support body 51 of the support bracket 5 is fixedly connected to the slider of the screw-guide mechanism. The horizontal position of the support body 51 can be adjusted by rotating the screw by the handle at the end of the screw.

[0096] Preferably, a plurality of guide posts 7 extending along the lifting direction are further provided on the corresponding support assembly, and one end of the guide post 7 is fixedly connected to the supporting bracket 5 and can move synchronously with the supporting bracket 5 .

[0097] Specifically, as shown in the accompanying drawings Figure 1 and Figure 2 As shown, in this embodiment, guide posts 7 are provided at four locations, one each located around the support base of the second support assembly 2 and slidingly engaging with the sleeve on the support base. The top of the guide posts 7 are fixedly connected to the bottom of the support bracket 5 (base 52) around the periphery, thereby increasing the number of sliding engagement structures between the support bracket 5 and the support base, and providing a guiding function for the lifting and lowering of the support bracket 5.

[0098] Preferably, the first support assembly 1 and the second support assembly 2 both have a V-shaped bracket 8, and the bracket 8 is used to limit the corresponding assembly parts;

[0099] For the support assembly provided with the supporting bracket 5 , the bracket 8 is constructed on the corresponding supporting bracket 5 .

[0100] Specifically, as shown in the accompanying drawings Figure 1 As shown, this embodiment provides a V-shaped bracket 8 for the cylindrical heat exchange tube bundle and housing. Bracket 8 serves to limit the heat exchange tube bundle or housing placed therein, improving placement stability. Furthermore, the slope of the V-shaped bracket 8 automatically returns to its center position due to the gravity of the corresponding heat exchange tube bundle or housing, facilitating control of alignment accuracy.

[0101] Furthermore, the floor rail assembly 3 includes a rack 31 , and an active motor 211 is provided on the active support seat 21 . The active motor 211 cooperates with the rack 31 through a gear 212 to drive the active support seat 21 to move along the floor rail assembly 3 .

[0102] Specifically, as shown in the accompanying drawings Figure 1 and Figure 2 As shown, the ground rail assembly 3 primarily provides a foundation for the movement and installation of the support assembly. The ground rail assembly 3 primarily comprises two parallel tracks and a rack 31 parallel to the tracks. The rack 31 is used to cooperate with the active support base 21 of the second support assembly 2 to achieve active movement of the active support base 21 along the tracks. The active support base 21 is provided with an active motor 211. The output shaft of the active motor 211 faces and is mounted with a gear 212. The gear 212 meshes with the rack 31, achieving movement along the tracks guided by the rack 31.

[0103] Furthermore, the first support assembly 1 includes a first support seat 11 and a second support seat 12 movably arranged on the ground rail assembly 3, and the first support seat 11 and / or the second support seat 12 have a positioning member, which is used to fix the position of the corresponding support seat on the ground rail assembly 3.

[0104] Specifically, the first support seat 11 and the second support seat 12 of the first support assembly 1 are also structurally designed to be movable along the floor rail assembly 3, except that in the normal assembly state, their positions on the floor rail assembly 3 remain fixed. The movement of the support seat of the first support assembly 1 is used to accommodate assembly parts of different lengths. For example, if the length of the assembly part is long, the first support seat 11 and / or the second support seat 12 can be moved along the floor rail assembly 3 by contacting the limiting state between the positioning member and the floor rail assembly 3, thereby increasing the distance between the first support seat 11 and the second support seat 12, thereby accommodating the longer assembly part; conversely, the distance between the first support seat 11 and the second support seat 12 can be reduced by movement to accommodate the shorter assembly part.

[0105] In this embodiment, the positioning member can be a positioning bolt, which cooperates with different screw holes provided along the track of the ground rail assembly 3 to achieve positioning.
