Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger production, in particular to an auxiliary supporting device for fixing heat exchange tubes of a heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers part of the heat of a hot fluid to a cold fluid. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes.

[0003] Heat exchange tubes and tube sheets for fixing the heat exchange tubes are arranged inside the heat exchanger. The tube sheets not only effectively fix the heat exchange tubes but also fix them to the outer shell. During the installation of the heat exchange tubes and the tube sheets, after the installation of one end of the tube sheet is completed, the other end of the heat exchange tube will sag, resulting in a deviation between the end of the tube and the hole on the surface of the tube sheet, making it difficult to fit the tube sheet on the end of the tube. Therefore, an auxiliary supporting device is required to effectively support the end of the tube, thereby facilitating the installation and fixing of the tube sheet. The existing installation method is that workers manually adjust the end of the tube during the installation process. During this process, the end of the tube is prone to repeated falling off, which makes installation very inconvenient. Utility Model Content

[0023] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0024] like Figure 1-5 The shown auxiliary support device for fixing the heat exchange tube of a heat exchanger includes a base 1, a supporting device 2 and a limiting mechanism 3. The supporting device 2 includes a mounting frame 21, a guide seat 22, an inserting plate 23 and a first adjusting knob 24. The mounting frame 21 is fixedly arranged on the upper surface of the base 1, the guide seat 22 is fixedly arranged on the inner side of the mounting frame 21, the inserting plate 23 is clamped inside the guide seat 22, and the first adjusting knob 24 is movably connected to the top of the inserting plate 23. The limiting mechanism 3 includes a support rod 31, two movable rods 32, a clamping strip 33 and a second adjusting knob 34. The support rod 31 is fixedly arranged on the surface of the inserting plate 23, the two movable rods 32 are clamped inside the support rod 31, the clamping strip 33 is fixedly arranged on the top of the movable rod 32, and the second adjusting knob 34 is connected to the end of the movable rod 32.

[0025] Specifically, the top of the first adjusting knob 24 passes through and extends to the outside of the top of the mounting bracket 21. The first adjusting knob 24 is connected to the mounting bracket 21 by a threaded connection. One end of the support rod 31 passes through and extends to the inside of one side of the mounting bracket 21. An adjustment hole that cooperates with the support rod 31 is provided on the side of the mounting bracket 21. The top of the clamping strip 33 passes through and extends to the outside of the top of the support rod 31. The clamping strips 33 at the top of the two moving rods 32 are staggered. One end of the second adjusting knob 34 passes through and extends to the outside of one side of the support rod 31 and is connected to the support rod 31 by a threaded connection. A card hole that cooperates with the guide seat 22 is provided at one end of the support rod 31. Support blocks are provided on both sides of the support rod 31. The inner side of the support block is in contact with the outer side of the mounting bracket 21, and a socket is provided on the surface of the plug plate 23.

[0026] In this embodiment, the first adjusting knob 24 is first adjusted according to the height of the heat exchange tube to be installed. Since the first adjusting knob 24 is connected to the top of the mounting bracket 21 by a thread, after rotating the first adjusting knob 24, the height of the plug plate 23 can be controlled to be adjusted in the guide seat 22. The guide seat 22 prevents the plug plate 23 from rotating, ensuring that the plug plate 23 can be adjusted vertically. The support rod 31 is fixed to the surface of the plug plate 23. The adjustment of the plug plate 23 can synchronously drive the height adjustment of the support rod 31. The surface of the plug plate 23 is provided with a hole for facilitating the insertion of the heat exchange tube.

[0027] Furthermore, the upper surface of the support rod 31 effectively supports the bottom of the heat exchange tube, and the clamping strip 33 effectively limits the end of the heat exchange tube. By adjusting the position of the two movable rods 32, the spacing between the staggered clamping strips 33 can be changed. By rotating the second adjustment knob 34, the spacing between the staggered clamping strips 33 can be matched with the outer diameter of the heat exchange tube, and the heat exchange tube clamped between the clamping strips 33 can be fixed, thereby effectively avoiding displacement and sagging of the pipe end, and facilitating the connection and fixation of the tube sheet.
