Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger tube penetration, in particular to a heat exchanger tube penetration platform. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. At present, heat exchangers on the market mainly use manual methods to insert heat exchange tubes, which have a long working cycle and require a lot of human resources, thus increasing production costs.

[0003] In addition, since the heat exchange tubes are integrated with the heat exchange plates, as shown in the attached figure of the specification, the heat exchange plates will be damaged when the heat exchange tubes are inserted into the heat exchange plates. For this reason, we propose a heat exchanger tube insertion platform. Summary of the invention

[0013] Preferably, a pushing block is installed on the belt body, and the purpose of the pushing block is to provide a pushing force for the heat exchange tube to facilitate the threading of the heat exchange tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention can replace manual pipe threading work through the transport platform, thereby improving work efficiency to a certain extent.

[0029] 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.

[0031] Example 1

[0032] The present invention provides a technical solution: a heat exchanger tube threading platform, including a transportation platform 1 for inserting a heat exchange tube 38 on a heat exchange plate 39, the transportation platform 1 includes a transmission device 2 for driving the heat exchange tube 38 to be transported on the platform and a moving device 3 for ensuring that the heat exchange tube 38 on the transmission device 2 can be inserted into the heat exchange plate 39, and a protective mechanism 4 is provided on one side of the transportation platform 1 to prevent the heat exchange tube 38 from being worn during the punching process.

[0033] The main function of the moving device 3 is to adjust the position of the heat exchange tube 38 on the transmission device 2. Because the heat exchange plate 39 itself is different and the heat exchange plate 39 is provided with through holes at different positions, the heat exchange tube 38 must be perforated by the moving device 3, that is, the heat exchange tube 38 is aligned with the through hole on the heat exchange plate 39 by the moving device 3.

[0034] The protection mechanism 4 includes a support frame 5 fixed to one side of the transport platform 1, a winding device 6 installed on the support frame 5, and a protective belt 7 fixed at one end to the winding device 6. A fixing member 8 is installed at one end of the protective belt 7 away from the winding device 6. The fixing member 8 can fix one end of the protective belt 7 to the insertion end of the heat exchange tube 38. The protective belt 7 is made of a flexible material, and the middle part of the protective belt 7 is concave. The fixing member 8 is an elastic leather rope 9, and the two ends of the leather rope 9 are fixed to the insertion end of the heat exchange tube 38. The winding device 6 includes a first motor 10 fixed to one side of the top of the support frame 5. A rotating shaft 11 is fixed to the output end of the first motor 10. The end of the rotating shaft 11 away from the first motor 10 is rotatably connected to the bearing seat. The protective belt 7 is wound on the rotating shaft 11. Protective plates 12 are arranged on both sides of the protective belt 7 to prevent it from axial deviation, and the protective plates 12 are installed on the rotating shaft 11.

[0035] The working principle of the protection mechanism 4 is to first suspend the transmission mechanism, put the elastic leather cord 9 on one end of the protective belt 7 on the heat exchange tube 38, and fix it by elastic force, then start the transmission device 2 and in the process of perforating the heat exchange tube 38, it is always located on the protective belt 7, and the movement of the protective belt 7 on the through hole can avoid the contact between the heat exchange tube 38 and the through hole wall, thereby protecting the heat exchange tube 38 from wear to a certain extent. When the heat exchange tube 38 is perforated, the elastic leather cord 9 is removed, and then the winding device 6 at this time retracts the protective belt 7. Since the protective belt 7 itself is made of flexible material, it will cause less damage to the heat exchange tube 38 during the recycling process;

[0036] The working principle of the winding device 6 is that when the protective belt 7 needs to be wound around the rotating shaft 11, the output end of the first motor 10 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 can realize the recovery of the protective belt 7. It is emphasized here that during the perforation of the protective belt 7 and the heat exchanger, the first motor 10 is not working, but the heat exchanger can drive the protective belt 7 to move, and its driving force is sufficient to rotate the rotating shaft 11, that is, when the first motor 10 is not working, the rotating shaft 11 can drive the output end of the first motor 10 to rotate.

[0037] The transmission device 2 includes a moving plate 13 fixed on the top of the moving device 3, and a second motor 14 is fixed on both sides of the top of the moving plate 13. A belt shaft 15 is fixed to the output end of the second motor 14, and the end of the belt shaft 15 away from the second motor 14 is rotatably connected to the bearing seat. A belt body 16 for transporting heat exchange tubes 38 is installed between the two groups of the belt shafts 15. A support platform 17 is fixed on the moving plate 13, and the table top of the support platform 17 is inserted between the belt bodies 16. A plurality of groups of V-shaped rollers 18 are equidistantly arranged between the table top of the support platform 17 and the belt body 16. A plurality of groups of belt bodies 16 are installed on the belt shaft 15. Protective belts 19 are connected to both sides of the belt body 16. Arc-shaped protrusions 20 are arranged between the two groups of the protective belts 19 and the belt body 16, and a pushing block 21 is installed on the belt body 16.

[0038] Example 2

[0039] The moving device 3 includes a first support plate 22 and a second support plate 23, a vertical plate 24 is arranged between the first support plate 22 and the second support plate 23, and the two are fixed by the vertical plate 24, both ends of the first support plate 22 are installed with a plane motion device 25 for driving the transmission device 2 to move horizontally, and the top of the plane motion device 25 is installed with a lifting device 26 for driving the transmission device 2 to move up and down, and the moving plate 13 is fixedly installed on the lifting device 26;

[0040] The first support plate 22 is provided with a sliding through hole 27, and a plurality of drive plates 28 are inserted through the sliding through hole 27. A sliding plate 29 is fixed on the top of the drive plate 28, and the bottom of the lifting device 26 is fixed on the sliding plate 29. A movable screw rod 30 is threadedly connected to the bottom of the sliding plate 29, and one end of the movable screw rod 30 is fixedly connected to the output end of the third motor 31 fixed on the first support plate 22, and the end of the movable screw rod 30 away from the third motor 31 is rotatably connected to the bearing seat;

[0041] A strip groove 32 is formed on the first support plate 22 below the sliding plate 29, a strip block 33 is fixed to the bottom of the sliding plate 29, and the sliding plate 29 is slidably connected in the strip groove 32 through the strip block 33;

[0042] The working principle of the planar motion device is further explained. When the horizontal position of the heat exchange tube 38 needs to be adjusted, the output end of the third motor 31 drives the movable screw 30 to rotate. At this time, the third motors 31 on both sides of the first support plate 22 work simultaneously, that is, the movable screw 30 rotates, which drives the drive plate 28 threadedly connected to the movable screw 30 to move. Since multiple groups of drive plates 28 are fixedly connected to the sliding plate 29, the movement of the drive plate 28 drives the sliding plate 29 to move, thereby realizing the horizontal movement of the heat exchange tube 38.

[0043] The lifting device 26 includes a fixed shell 34 fixed on the top of the sliding plate 29, and a lifting block 35 is slidably connected to the interior of the fixed shell 34. Square through holes 36 are opened on both sides of the second support plate 23. One end of the lifting block 35 is slidably inserted into the interior of the fixed shell 34, and the other end is fixed to the bottom of the movable plate 13. Two groups of electric push rods 37 for lifting the movable plate 13 are arranged between the movable plate 13 and the sliding plate 29.

[0044] The working principle of the lifting device 26 is that when the heat exchange tube 38 needs to be moved in the vertical direction, the vertical height of the movable plate 13 can be adjusted by two sets of electric push rods 37.
