Description

Technical Field

[0001] This application relates to the field of heat exchanger tube pack processing technology, and in particular to a heat exchanger tube pack loading tool. Background Technology

[0002] Heat exchanger tube banks typically consist of a series of parallel tubes used for various heat exchange processes, such as heating, cooling, condensation, and evaporation, and are widely used in various industries.

[0003] During the processing and production of heat exchanger tube banks, a post-processing process is required. This process includes: ultrasonic cleaning → alkaline air blowing → alkaline water washing → residual liquid air blowing → air tightness testing → tube drying.

[0004] In the above process, the carriers for the three main stations of ultrasonic cleaning, airtightness testing and tube drying are different. Therefore, when switching stations, each heat exchange tube bank needs to be manually loaded and unloaded, resulting in low efficiency. Therefore, this application proposes a new technical solution. Utility Model Content

[0005] To improve efficiency, this application provides a heat exchanger tube packing loading device.

[0006] This application provides a heat exchanger tube pack loading tool, which adopts the following technical solution:

[0007] A heat exchanger tube bank loading device includes a mobile trolley, a loading frame, and a positioning module. The loading frame is placed on the mobile trolley, and the positioning module is disposed on the loading frame. The positioning module is configured as multiple sets and arranged in a distribution on the inner bottom of the loading frame. The positioning module includes multiple positioning blocks arranged at equal intervals, and the arrangement direction of the positioning blocks is perpendicular to the arrangement direction of the positioning module. A heat exchanger tube bank can be inserted between two adjacent positioning blocks.

[0008] Optionally, a pressure strip is detachably connected to the upper end of the loading frame. The pressure strip is located above the heat exchange tube bank. The length direction of the pressure strip is set along the arrangement direction of the positioning blocks. A limit block is fixedly connected to the lower surface of the pressure strip. Multiple limit blocks are set and arranged at equal intervals along the length direction of the pressure strip. The limit blocks are inserted between two adjacent heat exchange tube banks.

[0009] Optionally, the two ends of the pressure strip are respectively mounted on the upper frame of the loading frame. A fixing block is fixedly connected to one side of the loading frame located at the end of the pressure strip. A bracket is fixedly connected to the side of the loading frame located at the end of the pressure strip away from the fixing block. A pin is slidably connected to the bracket. The fixing block has a pin hole for the pin end to be inserted. The pin end passes through the end of the pressure strip and is inserted into the pin hole of the fixing block.

[0010] Optionally, a second fixing block is fixedly connected between the loading frame and the end of the pressure strip. A space is left between the first fixing block and the second fixing block for the pressure strip to be placed. The end of the pin passes through the second fixing block and the end of the pressure strip in sequence and is inserted into the pin hole of the first fixing block.

[0011] Optionally, it also includes two mating clamps, each with a cavity. The two mating clamps are detachably connected to the upper and lower frame edges of the outer side of the loading frame. The mating clamps facing the heat exchange tube bank are equipped with multiple pipe interfaces for connecting the inlet / outlet ports of each heat exchange tube bank. The mating clamps facing away from the pipe interfaces are provided with a gas interface. Both the pipe interface and the gas interface are connected to the cavity of the mating clamp.

[0012] Optionally, bolts are respectively provided at both ends of the interlocking clamp, and the bolts are detachably connected to the outer side of the loading frame.

[0013] Optionally, the two ends of the mating clamp are respectively provided with strip grooves, the end of the strip groove near the side of the mating clamp is open, and the bolt passes through the strip groove.

[0014] Optionally, the positioning block and the limiting block have inclined guide surfaces on both sides of the end facing the heat exchange tube bank.

[0015] In summary, this application includes the following beneficial technical effects: the positioning block realizes the positioning of the heat exchange tube bank, and can also load multiple heat exchange tube banks into the loading frame, thereby enabling the one-time transfer and transportation of multiple heat exchange tube banks, using a single tooling to meet the transfer needs of three workstations. Furthermore, since the heat exchange tube banks are arranged sequentially, it facilitates subsequent processing procedures such as testing and drying, thereby improving efficiency.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a heat exchanger tube packing loading device.

[0022] Reference Figure 1 and Figure 2 The heat exchanger tube bank loading device includes a mobile trolley 1, a loading frame 2, and a positioning module. The loading frame 2 is a five-sided frame structure assembled with an opening at the top. The upper edge of the loading frame 2 is higher than the upper edge of the heat exchanger tube bank. The loading frame 2 is placed on the mobile trolley 1 for easy movement. The positioning module is fixedly installed on the bottom inner side of the loading frame 2, and multiple positioning modules are arranged and distributed on the bottom inner side of the loading frame 2. The positioning module includes multiple positioning blocks 3 arranged at equal intervals. The arrangement direction of the positioning blocks 3 is perpendicular to the arrangement direction of the positioning module. The distance between two adjacent positioning blocks 3 is slightly greater than the thickness of the heat exchanger tube bank, so that the heat exchanger tube bank is inserted vertically between two adjacent positioning blocks 3. Therefore, multiple heat exchanger tube banks can be fixed in an equidistant arrangement within the loading frame 2.

[0023] Through the above settings, the positioning block 3 can locate the heat exchange tube array and load multiple heat exchange tube arrays into the loading frame 2. This enables the one-time transfer and transportation of multiple heat exchange tube arrays, using a single tooling to meet the transfer needs of three workstations. The loading frame 2 can be placed directly into the ultrasonic tank for ultrasonic cleaning and other related cleaning processes. Afterward, by lifting the loading frame 2, multiple heat exchange tube arrays are transferred from the ultrasonic tank to the mobile trolley 1. The mobile trolley 1 facilitates movement to different workstations. Since the heat exchange tube arrays are arranged sequentially, it facilitates subsequent testing, drying, and other processing operations, thereby improving efficiency.

[0024] Reference Figure 2 and Figure 3 To ensure the heat exchange tube bank is more stably positioned within the loading frame 2, a pressure strip 4 is detachably connected to the upper end of the loading frame 2. The pressure strip 4 is located above the heat exchange tube bank, and its length is aligned with the arrangement direction of the positioning blocks 3. Limiting blocks 41 are fixedly installed on the lower surface of the pressure strip 4. Multiple limiting blocks 41 are arranged at equal intervals along the length of the pressure strip 4. The distance between two adjacent limiting blocks 41 is consistent with the distance between two adjacent positioning blocks 3, allowing the limiting blocks 41 to be inserted between the upper ends of two adjacent heat exchange tube banks. This makes the heat exchange tube bank more stably positioned within the loading frame 2 and prevents displacement.

[0025] To facilitate the insertion of each heat exchange tube bank into the space between two adjacent positioning blocks 3, inclined guide surfaces are provided on both sides of the upper end of the positioning block 3. Similarly, to facilitate the insertion of the limiting block 41 into the space between each heat exchange tube bank for positioning, inclined guide surfaces are provided on both sides of the lower end of the limiting block 41.

[0026] Reference Figure 2 and Figure 3 Regarding the detachable connection between the pressure strip 4 and the upper end of the loading frame 2, this embodiment is configured as follows:

[0027] The two ends of the pressure strip 4 are respectively placed on the upper edge of the loading frame 2, and the loading frame 2 is fixedly installed on both sides of the ends of the pressure strip 4 with fixing block 1 5 and fixing block 2 6 respectively. The distance between fixing block 1 5 and fixing block 2 6 is slightly larger than the width of the pressure strip 4, so that the pressure strip 4 can be placed between fixing block 1 5 and fixing block 2 6, which serves to limit the position of the pressure strip 4.

[0028] A bracket 7 is fixedly installed on the side of the loading frame 2 opposite to the end of the pressure strip 4 on the side of the fixing block 2 6. The bracket 7 is slidably connected to a horizontally sliding pin 71. In this embodiment, the bracket 7 can be a U-shaped plate, with both ends of the bracket 7 extending upwards. The two ends of the pin 71 are slidably inserted through the two ends of the bracket 7. The side wall of the fixing block 1 5 facing the pressure strip 4 has a pin hole for the end of the pin 71 to be inserted. By moving the pin 71, the end of the pin 71 can be sequentially inserted through the fixing block 2 6, the end of the pressure strip 4, and finally inserted into the pin hole of the fixing block 1 5, thereby fixing the pressure strip 4. It should be noted that the installation method between the two ends of the pressure strip 4 and the frame edge of the loading frame 2 adopts the above-described fixing method. Therefore, the fixing block 1 5, fixing block 2 6, bracket 7, and pin 71 are all provided in two sets and symmetrically arranged on both sides of the loading frame 2.

[0029] Reference Figure 2 and Figure 3 In another embodiment of this application, in order to further improve efficiency in the subsequent airtightness / drying station, this application also includes two interlocking clamps 8. The two interlocking clamps 8 are detachably connected to the upper and lower frame edges of the outer side of the loading frame 2, and the interlocking clamps 8 are provided with cavities. The side of the interlocking clamps 8 facing the heat exchange tube row is equipped with a plurality of pipe interfaces 81 for connecting the inlet / outlet ports of each heat exchange tube row. The pipe interfaces 81 are provided in a one-to-one correspondence with each heat exchange tube row. The side of the interlocking clamps 8 away from the pipe interfaces 81 is provided with an air interface 82. Both the pipe interfaces 81 and the air interface 82 are connected to the cavity of the interlocking clamps 8 and are both sealed.

[0030] When the loading frame 2 is moved to the airtightness / drying station by the mobile trolley 1, the pipe interfaces 81 of the two interlocking clamps 8 are connected to the inlet / outlet ports of the heat exchange tube bank respectively. When at the airtightness testing station, the air inlet port of the airtightness testing equipment is connected to the air interface 82 of any one of the interlocking clamps 8, and the air interface 82 of the other interlocking clamp 8 is blocked. This allows for batch testing of multiple heat exchange tube banks at the same time, distinguishing bubbling defective products, eliminating the need for loading and unloading, and improving efficiency.

[0031] When in the drying station, the air inlet port of the drying equipment is connected to the air interface 82 of any one of the interlocking clamps 8, and the air interface 82 of the other interlocking clamp 8 is opened, so that multiple heat exchange tube banks can be dried in batches at the same time without loading and unloading, thus improving efficiency.

[0032] Reference Figure 3 To facilitate the disassembly of the mating clamp 8, bolts 9 are detachably connected to the outer frame edge of the loading frame 2. Strip grooves 91 are respectively opened through the two ends of the mating clamp 8, and the end of the strip groove 91 near the side of the mating clamp 8 is open. The bolts 9 are inserted into the strip grooves 91, thereby facilitating the disassembly of the mating clamp 8.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
