Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat exchanger tube bundle extraction, in particular to a heat exchanger tube bundle extraction tool. Background Art
[0002] At present, when repairing heat exchangers, the complexity of the on-site environment often brings many challenges to the construction. The narrowness of the working space, especially the crowded position under the frame, makes it difficult to implement traditional construction methods, which undoubtedly increases the difficulty and workload of the construction workers. First, due to space limitations, traditional large-scale mechanical equipment such as core pullers cannot enter the working area, and there are no fixed anchor points around. Construction workers may need to use smaller tools to complete the core pulling work, or use manual work, which not only increases the labor intensity but also prolongs the construction time. Secondly, the narrow working position may also limit the movement of construction workers during operation, which not only affects the efficiency of construction, but also may increase safety risks. Construction workers need to perform precise operations in a limited space, which requires them to have superb skills and rich experience. In addition, due to the extension of the repair time, construction workers may need to work for a long time in an unsuitable environment, such as in a high temperature, high pressure or toxic gas environment, which is a great test for the physical health and mental state of construction workers.

[0023] Combination Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a heat exchanger 4 tube bundle extraction tool, including a support frame 1, a first support member 2 and a second support member 3.
[0024] The first support member 2 and the second support member 3 are both arranged between the support frame 1 and the heat exchanger 4 and are arranged opposite to each other in the horizontal direction. The support frame 1 is provided with a first limiting hole 11 and a second limiting hole 12, and the heat exchanger 4 is provided with a third limiting hole 41 and a fourth limiting hole 42. The first limiting hole 11 is arranged correspondingly to the third limiting hole 41, and the second limiting hole 12 is arranged correspondingly to the fourth limiting hole 42.

The support frame 1, the first support member 2 and the second support member 3 enclose an operating space to facilitate the extraction of the tube bundle.
[0025] The heat exchanger 4 tube bundle extraction tooling provided by the embodiment of the present disclosure is adopted, by setting a support frame 1, a first support member 2 and a second support member 3, the first support member 2 and the second support member 3 are simultaneously arranged between the support frame 1 and the heat exchanger 4, the tube bundle in the heat exchanger 4 is pulled out of the heat exchanger 4 by a crane or other pulling tool, and moved along the first support member 2 and the second support member 3 to the operating space, and the tube bundle extraction process is completed. Compared with the related art, the heat exchanger 4 tube bundle extraction tooling has a simple structure, a small footprint, and can be flexibly used in places where a core pulling machine cannot be used, and is convenient for on-site operations.
[0026] Based on the above technical solution, the number of the first limiting holes 11 and the second limiting holes 12 are both multiple, and the multiple first limiting holes 11 and the second limiting holes 12 all extend along the width direction of the support frame 1, and are used to adjust the distance between the first support member 2 and the second support member 3 in the horizontal direction.
[0027] The tube bundle sizes of heat exchangers 4 of different models are different, and the distances between the corresponding third limiting holes 41 and the fourth limiting holes 42 are different. At this time, it is necessary to select the corresponding first limiting holes 11 and the second limiting holes 12 to facilitate adjusting the distance between the first support member 2 and the second support member 3 to be the same, so that it is more stable when placing tube bundles of different models, thereby improving the versatility of the tooling of the present application and being applicable to different models of heat exchangers 4 for replacing tube bundles.
[0028] On the basis of the above technical solution, the support frame 1 includes a first vertical section 13, a second vertical section 14 and a horizontal beam 15, the second vertical section 14 is arranged opposite to the first vertical section 13, one end of the first vertical section 13 is arranged on the ground, and the other end is connected to one end of the horizontal beam 15, one end of the second vertical section 14 is arranged on the ground, and the other end is connected to the other end of the horizontal beam 15; wherein, the first limiting hole 11 and the second limiting hole 12 are arranged on the horizontal beam 15.
[0029] The arrangement of the first vertical section 13 and the second vertical section 14 can support and fix the cross beam 15 . The arrangement of the cross beam 15 can fix the first support member 2 and the second support member 3 .

Specifically, the outer diameter of the installation matching tube 151 is the same as the inner diameter of the installation tube 16, so that the two ends of the cross beam 15 are respectively inserted downward into the first vertical section 13 and the second vertical section 14, and the installation matching tube 151 is inserted into the installation tube 16 to fix the cross beam 15 on the first vertical section 13 and the second vertical section 14.

[0035] The setting of the base 18 can stabilize the placement of the support frame 1. Compared with the support frame 1 without the base 18, the contact area between the support frame 1 and the ground is increased, and the contact between the base 18 on both sides of the support frame 1 and the ground is changed from one end of the first vertical section 13 and the second vertical section 14 being in contact with the ground.

[0038] Specifically, the third limiting hole 41 and the fourth limiting hole 42 are provided on the flange 43, and are arranged in sequence at intervals along the circumference of the flange 43. The third limiting hole 41 and the fourth limiting hole 42 are arranged axially symmetrically. The first support member 2 and the second support member 3 can select the third limiting hole 41 and the fourth limiting hole 42 according to actual working conditions, and adjust the distance between the first support member 2 and the second support member 3 to make the distance between the first support member 2 and the second support member 3 at the end of the heat exchanger 4 equal to the distance between the first support member 2 and the second support member 3 at the end of the support frame 1, and the third limiting hole 41 and the fourth limiting hole 42 are at the same height from the ground to avoid displacement of the tube bundle when placed, so as to stably receive the tube bundle of the heat exchanger 4.
[0039] Based on the above technical solution, bolts are provided at both ends of the first support member 2 and the second support member 3, and the heat exchanger 4 tube bundle extraction tooling also includes nuts, and the bolts are sequentially passed through the first or second or third or fourth limiting holes 42 and the nuts to fix the first support member 2 and the second support member 3.
[0040] The combination of bolts and nuts further fixes the support frame 1, the first support member 2 and the second support member 3, and the tooling and the heat exchanger 4. It can be understood that the fixing form can also adopt other detachable connection and fixing methods. The present application does not limit the fixing form, and it is sufficient to achieve detachable connection and have a fixing effect.
