Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger processing, in particular to a heat exchanger installation device. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. With the maturity of heat exchanger production and application technology, it is often necessary to assemble some larger heat exchangers to improve the heat exchange effect, resulting in an increasing number of heat pipes inside the tubular heat exchanger. In the tubular heat exchangers currently on the market, the installation of heat exchange tubes is often done manually, which has a high labor cost. Especially for the case of a large number of heat exchange tubes, there are problems such as difficulty in installation and low installation efficiency.

[0003] The Chinese patent publication number CN111136438A discloses a heat exchanger installation device, which can realize automatic installation of heat exchange tubes, increase installation speed, reduce labor intensity, and enable the heat exchange tubes to be better inserted into the holes on the fixed tube sheet of the heat exchanger through mechanical automatic installation, thereby greatly improving the installation quality.

[0017] (1) The heat exchanger installation equipment can realize the simultaneous insertion of multiple heat exchange tubes into the sockets on the end cover by setting up multiple supporting frames, thereby greatly improving the installation speed of the heat exchange tubes and thus improving the production efficiency of the heat exchanger.

[0018] (2) The heat exchanger installation device adjusts the heat exchange tubes on the support frame to align with a row of sockets on the end cover through the slide adjustment module, thereby ensuring the installation accuracy of the heat exchange tubes. Under the setting of the fixing component, the end cover is fixed to ensure the stability of the heat exchange tube during installation.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] See also Figure 1-Figure 11 The embodiment of the present invention provides a technical solution: a heat exchanger installation device, including a first base 1, and also including a movable frame 13, the movable frame 13 is slidably arranged on the upper surface of the first base 1, and a support frame 19 for holding the heat exchange tube 20 is installed at equal intervals on one side of the movable frame 13, and a groove of a "V"-shaped structure is provided on the upper surface of the support frame 19 to limit the heat exchange tube 20 and improve the stability of the heat exchange tube 20 during installation. In addition, it should be noted that the length of the support frame 19 is less than the length of the heat exchange tube 20, so that the heat exchange tube 20 can be pushed to slide on the support frame 19 later, thereby facilitating the installation of the heat exchange tube 20. In order to facilitate the adjustment of the position of the support frame 19 relative to the socket on the end cover 26, a slide adjustment module is provided at one end of the movable frame 13 to adjust the heat exchange tube 20 on the support frame 19 to align with a row of sockets on the end cover 26, and a pusher assembly is provided at the other end of the movable frame 13 to push the heat exchange tube 20 and insert the heat exchange tube 20 into the corresponding socket on the end cover 26.

[0038] In addition, to facilitate the fixation of the end cover 26, the heat exchanger installation equipment provided in this embodiment also includes a fixing component, which is used to fix the end cover 26, and an adjustment component is provided on one side of the fixing component to drive the end cover 26 to rotate so that any vertical row of sockets on the end cover 26 can be parallel to the connecting line of the support frame 19.

[0039] In this embodiment, by providing a plurality of support racks 19, a plurality of heat exchange tubes 20 can be simultaneously inserted into the sockets on the end cover 26, thereby greatly improving the installation speed of the heat exchange tubes 20 and thus improving the production efficiency of the heat exchanger. It should be noted that the total number of support racks 19 is the same as the number of the most sockets in a longitudinal row on the end cover. According to the actual number of sockets in the longitudinal row, the heat exchange tubes 20 on the support racks 19 are manually adjusted. When the number of sockets in the longitudinal row is less than the total number of support racks 19, the heat exchange tubes 20 that do not correspond to the sockets are manually and symmetrically removed. This makes it convenient to install the heat exchange tubes 20 on the end covers 26 with array sockets of different shapes, such as the sockets on the end covers 26 being in a regular octahedral shape, a circular array, etc.

[0040] like Figure 1-Figure 5 As shown, the fixing assembly provided in this embodiment includes a workbench 27 installed on one side of the first base 1, a mounting frame 21 is fixed on the workbench 27, a swivel 22 is rotatably installed in the mounting frame 21, the swivel 22 and the mounting frame 21 are connected by bearings, both ends of the swivel 22 extend to the outside of the mounting frame 21, and cylinders 24 are fixed on the outer side of the swivel 22 near one end along the circumferential direction at equal intervals. There are at least three cylinders 24, and the telescopic ends of the three cylinders 24 pass through the inner wall of the swivel 22 and are installed with clamping columns 25. Preferably, a notch is provided in the middle section of the clamping column 25 to improve the stability of the end cover 26 during installation. In addition, the three cylinders 24 are synchronously extended and retracted to achieve the fixation of the end cover 26, so that the end cover 26 and the swivel 22 are in concentric circles, thereby facilitating the later positioning of the end cover 26.

[0041] In this embodiment, the end cover 26 is installed inside the swivel 22, and the cylinder 24 is started to drive the clamping column 25 to move. With the cooperation of multiple clamping columns 25, the end cover 26 is clamped and fixed to improve the stability of the end cover 26 and the heat exchange tube 20 during installation.

[0042] like Figure 1-Figure 5 As shown, the adjustment assembly provided in this embodiment includes a second motor 29 fixed on the mounting frame 21, a driving gear 30 is fixedly sleeved at the output end of the second motor 29, a ring gear 23 is fixedly sleeved on the outer side of the rotating ring 22 near the other end, and the ring gear 23 is meshed with the driving gear 30.

[0043] In this embodiment, the second motor 29 drives the driving gear 30 to rotate. Through the meshing between the driving gear 30 and the annular gear 23, the swivel ring 22 rotates along with the annular gear 23, thereby adjusting the position of the end cover 26 to adjust the position of the jack array on the end cover 26 in the plane, so that any longitudinal row of jacks on the end cover 26 can be parallel to the connecting line of the bearing frame 19, thus preparing for the heat exchange tube 20 to be inserted into the jacks.

[0044] As Figure 1 , Figure 3 and Figure 6 shown, to improve the accuracy during the installation of the heat exchange tube 20 and the end cover 26, a support rod 8 is fixed on one side of the upper surface of the first base 1 away from the workbench 27. A CCD industrial camera 9 is installed on the support rod 8, and a control cabinet 10 electrically connected to the CCD industrial camera 9 is provided on one side of the support rod 8. Preferably, a signal processor is further provided inside the control cabinet 10.

[0045] In this embodiment, the CCD industrial camera 9 monitors the positions of the jacks on the end cover 26 to ensure that any longitudinal row of jacks on the end cover 26 can be parallel to the connecting line of the bearing frame 19, thus preparing for the heat exchange tube 20 to be inserted into the jacks. In addition, the CCD industrial camera 9 can also be used to determine the positions of the jacks on the end cover 26 for adjusting the alignment of the heat exchange tube 20 with the corresponding jacks.

[0046] As Figure 6-Figure 10 shown, the sliding table adjustment module provided in this embodiment includes a first motor 18 fixed to the upper end of the moving frame 13. A trapezoidal lead screw 37 rotatably connected to the moving frame 13 is installed at the output end of the first motor 18. Guide rods 38 are provided on both sides of the trapezoidal lead screw 37 inside the moving frame 13. A moving seat 35 (the distance between adjacent moving seats 35 is equal to the distance between vertically adjacent jacks on the end cover 26) is provided on the two guide rods 38, and one side of the moving seat 35 is fixedly connected to the bearing frame 19; spiral grooves are provided on the trapezoidal lead screw 37, and screw nuts are respectively installed at the cooperation positions of each moving seat 35 and the trapezoidal lead screw 37. By rotating the trapezoidal lead screw 37, multiple moving seats 35 can be driven to move up or down simultaneously, so that the heat exchange tube 20 is aligned with a row of jacks on the end cover 26.

[0047] The moving seat 35 has a "U" - shaped structure. In addition, a displacement sensor is installed on the moving seat 35, and the signal output end of the displacement sensor is electrically connected to the control cabinet 10 for monitoring the moving distance of the moving seat 35.

[0048] As Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the pushing assembly provided in this embodiment includes a second electric telescopic cylinder 16 fixed to the outside of the mobile frame 13 and a partition 36 fixed to the inside of the mobile frame 13 at one end of the mobile seat 35. The telescopic end of the second electric telescopic cylinder 16 is fixed with a connecting plate 17. A movable plate 14 is slidably installed inside the mobile frame 13. One side of the movable plate 14 is fixedly connected to the connecting plate 17, and a transparent push plate 15 is installed on the other side of the movable plate 14. The transparent push plate 15 is arranged to avoid blocking the heat exchange tube 20, so that the CCD industrial camera 9 can monitor the position deviation between the heat exchange tube 20 and the corresponding socket. The transparent push plate 15 is used to push the heat exchange tube 20 on the carrier frame 19 to move. Preferably, guide rails are symmetrically arranged inside the mobile frame 13, and the guide rails are slidably connected to the upper and lower ends of the movable plate 14 to improve the stability of the movable plate 14 when it moves.

[0049] In this embodiment, the second electric telescopic cylinder 16 drives the connecting plate 17 to move, and the connecting plate 17 drives the movable plate 14 to slide in the movable frame 13, thereby driving the transparent push plate 15 to move, so as to push the heat exchange tube 20 to move on the supporting frame 19.

[0050] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in order to facilitate the adjustment of the relative position between the end cover 26 and the carrier frame 19, a storage cavity 39 slidably connected to the workbench 27 is opened in the first base 1, and a hydraulic cylinder 34 is installed inside the first base 1. One end of the workbench 27 is inserted into the storage cavity 39, and a support leg 28 is fixed to the lower surface of the other end of the workbench 27. The support leg 28 is fixedly connected to the telescopic end of the hydraulic cylinder 34, and a roller is installed at the bottom of the support leg 28.

[0051] In this embodiment, the hydraulic cylinder 34 is extended and retracted to drive the workbench 27 to move, which facilitates the sliding of the workbench 27 inside the storage chamber 39, thereby adjusting the relative position between the upper end cover 26 of the workbench 27 and the support frame 19 to facilitate the installation of heat exchange tubes 20 of different lengths. In this process, the stability of the workbench 27 during movement can be improved by setting the support legs 28 and the rollers.

[0052] like Figure 1 , Figure 2 , Figure 3 and Fig.11As shown, in order to facilitate the installation of the heat exchange tube 20 on the supporting frame 19, a loading assembly is fixed on one side of the first base 1 in this embodiment, and the loading assembly includes a second base 2 fixed on one side of the first base 1, and a fixing frame 3 is fixed on the upper surface of the second base 2. Support plates 4 are fixed inside the fixing frame 3 at equal intervals from top to bottom. The number of support plates 4 is the same as that of the supporting frame 19, and a limiting stop bar 31 is installed on the upper surface of the supporting plate 4 near the supporting frame 19. Through the setting of the limiting stop bar 31, the movement of the heat exchange tube 20 on the supporting plate 4 is limited, thereby improving the stability of the heat exchange tube 20 during loading.

[0053] A movable frame 5 is slidably mounted on one side of the second base 2, and push rods 6 slidably connected to the upper surface of the supporting plate 4 are evenly installed on one side of the movable frame 5. A first electric telescopic cylinder 7 is provided inside the first base 1, and the first electric telescopic cylinder 7 is used to drive the movable frame 5 to move toward the supporting frame 19.

[0054] In this embodiment, it is preferred that the single telescopic amount of the first electric telescopic cylinder 7 is the same as the outer diameter of the heat exchange tube 20, and a contact switch is installed on the side of the support frame 19 facing the support plate 4. When the contact switch is triggered, the first electric telescopic cylinder 7 is controlled to work. During the loading process, the movement distance of the support frame 19 is controlled by the slide adjustment module, so that the heat exchange tube 20 on the support frame 19 is aligned with the corresponding socket on the end cover 26, and the movable frame 5 is driven to move by the first electric telescopic cylinder 7, so that the movable frame 5 drives the push rod 6 to move on the support plate 4, and then pushes the heat exchange tube 20 on the support plate 4 to move, so that the heat exchange tube 20 close to the support frame 19 passes the limit stop bar 31, and further the heat exchange tube 20 is installed on the support frame 19, thereby realizing the installation of the heat exchange tube 20.

[0055] like Figure 3 , Figure 6 and Figure 7 As shown, in order to facilitate the adjustment of the position of the movable frame 13 on the first base 1, so that the heat exchange tubes 20 can be inserted into the sockets on the end cover 26 in sequence, that is, the heat exchange tubes 20 can be inserted in sequence along the moving direction of the movable frame 13, a slide groove 11 is provided on the upper surface of the first base 1 along the sliding direction of the movable frame 13, and a screw rod 12 is rotatably installed inside the slide groove 11. A third motor 32 for driving the screw rod 12 to rotate is provided on the outer side of the first base 1, and a travel slider 33 threadedly connected to the screw rod 12 is fixed at the lower end of the movable frame 13.

[0056] In this embodiment, a distance sensor is installed on the upper surface of the first base 1. The distance sensor is connected to the control cabinet 10 for communication, and is used to measure the horizontal distance between the lower end of the carrier 19 and the distance sensor, which is recorded as c. In addition, the distance sensor and the central axis of the rotating ring 22 are in the same vertical plane. The control cabinet 10 controls the third motor 32 to work, and when the third motor 32 works, it drives the screw rod 12 to rotate. Through the threaded connection between the screw rod 12 and the travel slider 33, the travel slider 33 drives the moving frame 13 to slide, thereby driving the carrier 19 to move, and controlling the size of c until the heat exchange tube 20 is inserted into the corresponding jack, and the control cabinet 10 sends a signal to stop the third motor 32.

[0057] like Figure 1 As shown, in order to improve the stability of the moving frame 13 when sliding, slide rails are symmetrically arranged on the upper surface of the first base 1, and sliding notches symmetrically opened on the lower surface of the moving frame 13 for sliding connection with the slide rails.

[0058] When in use (working), the end cover 26 is installed inside the swivel 22, and the cylinder 24 is started. The clamping column 25 is driven to move by the cylinder 24. With the cooperation of multiple clamping columns 25, the end cover 26 is clamped and fixed to improve the stability of the end cover 26 and the heat exchange tube 20 during installation. The driving gear 30 is driven to rotate by the second motor 29. The swivel 22 rotates with the ring gear 23 through the engagement between the driving gear 30 and the ring gear 23, so that the position of the end cover 26 is adjusted to adjust the position of the array of sockets on the end cover 26 in the plane, so that any vertical row of sockets on the end cover 26 can be parallel to the connection line of the support frame 19, thereby preparing for the insertion of the heat exchange tube 20 into the socket.

[0059] During the loading process, the position of the carrier frame 19 is controlled by the slide adjustment module to align the carrier frame 19 with the corresponding carrier plate 4, and the first electric telescopic cylinder 7 is controlled to work, and the movable frame 5 is driven to move by the first electric telescopic cylinder 7, so that the movable frame 5 drives the push rod 6 to move on the carrier plate 4, and then pushes the heat exchange tube 20 on the carrier plate 4 to move, so that the heat exchange tube 20 close to the carrier frame 19 passes the limit stop bar 31, and further the heat exchange tube 20 is installed on the carrier frame 19, thereby realizing the installation of the heat exchange tube 20.

[0060] Start the third motor 32. When the third motor 32 is working, it drives the lead screw 12 to rotate. Through the threaded connection between the lead screw 12 and the travel slider 33, the travel slider 33 drives the movable frame 13 to slide, thereby driving the carrier 19 to move. When the carrier 19 moves to the desired position, start the first motor 18. The first motor 18 drives the trapezoidal lead screw 37 to rotate. The rotation of the trapezoidal lead screw 37 can drive multiple movable seats 35 to move up or down at the same time, thereby aligning the heat exchange tube 20 with a row of sockets on the end cover 26.

[0061] After the position adjustment of the carrier frame 19 is completed, the second electric telescopic cylinder 16 is started, and the connecting plate 17 is driven to move by the second electric telescopic cylinder 16, and the movable plate 14 is driven to slide in the movable frame 13 by the connecting plate 17, thereby driving the transparent push plate 15 to move, so as to push the heat exchange tube 20 to move on the carrier frame 19, so that the heat exchange tube 20 is inserted into the socket on the end cover 26.
