[0024] In order to describe the technical solution of the above utility model in more detail, specific embodiments are listed below to demonstrate the technical effect; it should be emphasized that these embodiments are used to illustrate the utility model but not to limit the scope of the utility model.

[0025] The utility model provides a heat exchanger assembly tool for a kettle, such as Figure 1 and Figure 2As shown, it includes a crossbeam 10, two legs 20 and two pulley blocks 30, the legs 20 are respectively installed under the crossbeam 10, and the pulley blocks 30 are detachably installed at the bottom of the legs 20; two limit slots 02 are provided on the inner wall of the tank body 01 to be installed, and the positions of the pulley blocks 30 correspond to the positions of the limit slots 02 one by one. The use of the pulley blocks 30 can reduce the resistance of the relative sliding between the tooling and the tank body 01, and avoid the destructive effect of excessive thrust on the equipment. The tooling provided by the utility model can use the limit of the pulley blocks 30 and the limit slots 02 to achieve the rapid alignment and movement of the heat exchanger 03 and the tank body 01, so as to quickly and smoothly send the heat exchanger 03 to the designated position in the tank body 01; the tooling provided by the utility model has a reliable structure and safe installation; each component is easy to manufacture and low cost.

[0026] In some embodiments, please refer to Figure 1 The two legs 20 are arranged in an "eight" shape, that is, the two legs 20 are tilted outward from top to bottom to increase the support stability of the legs 20 on the beam 10 and prevent the tooling from swaying left and right. For example, the angle between the two legs can be 60° to prevent the tooling from tipping over.

[0027] In some embodiments, please refer to Figure 1 The pulley block 30 is connected to the bottom of the leg 20 by bolts 21. The installation and removal of the pulley block 30 can be completed by installing and removing the bolts 21, so that after the equipment is in place, the bottom of the beam 10 can be supported by a jack, the heat exchanger 02 can be raised, and then the pulley block 30 can be removed. The pulley block 30 can be a double-wheel pulley block.

[0028] In some embodiments, please refer to Figure 1 A connecting beam 31 is installed between the two pulley blocks 30, so as to reinforce the entire tooling and further increase the stability of the tooling. In one or more embodiments, the pulley block 30 and the connecting beam 31 are connected by bolts.

[0029] In some embodiments, the connecting beam 31 is made of channel steel, which has sufficient strength and stability and is lighter than a solid support. Connectors can be welded at both ends of the channel steel to ultimately achieve connection with the pulley block 30, so that the channel steel can be removed after the equipment is in place to complete the subsequent lifting work of the jack.

[0030] In some embodiments, the crossbeam 10 may be made of 350mm×250mm H-shaped steel, so that it can bear the weight of the heat exchanger 03 and reduce the overall weight of the tooling. In this application, H-shaped steel and channel steel are used as the main component materials to ensure the stability of the tooling and reduce the weight of the tooling.

[0031] In some embodiments, please refer to Figure 1 The two sides of the cross beam 10 are respectively provided with a clearance groove 11, which can be obtained by cutting off the area where the head and tail ends of the cross beam 10 interfere with the support of the tank body 01, so as to avoid interference between the cross beam 10 and the tank body 01; the end of the clearance groove 11 is welded with a 14mm reinforcing steel plate 12 to further ensure the overall stability of the tooling.

[0032] The following is a detailed description of the application process of the in-kettle heat exchanger assembly tooling provided by the utility model:

[0033] 1. If Figure 2 As shown, install the temporary sliding limit slot 02 in the tank body 01, place the No. 1 tool 04 on the limit slot 02, and hoist the heat exchanger 03 onto the No. 1 tool 04;

[0034] 2. If Figure 3 As shown, the hanging beam 06 near the side of the No. 1 tooling 04 is removed and inserted into the tank body 01, and the No. 2 tooling 05 is installed in the tank body 01;

[0035] 3. Remove the hanging beam 06 near the side of tooling 05 No. 2, and use two tools to carry the heat exchanger 03 and push it into the designated position, such as Figure 4 As shown, the jack 07 is installed and the pulley blocks 30 of the two toolings are removed, and the heat exchanger 03 is slowly lowered, and the heat exchanger in the kettle is installed in place.

[0036] When the sizes of the heat exchanger 03 and the tank body 01 remain unchanged, the entire tooling can be reused, further saving costs.

[0037] In summary, the in-kettle heat exchanger assembly tool provided by the utility model comprises a crossbeam 10, two legs 20 and two pulley blocks 30, wherein the legs 20 are respectively installed below the crossbeam 10, and the pulley blocks 30 are detachably installed at the bottom of the legs 20; two limit slots 02 are provided on the inner wall of the tank body 01 to be installed, and the positions of the pulley blocks 30 correspond to the positions of the limit slots 02. The tool provided by the utility model can utilize the limit of the pulley blocks 30 and the limit slots 02 to realize the rapid alignment and movement of the heat exchanger 03 and the tank body 01, thereby quickly and smoothly delivering the heat exchanger 03 to the designated position in the tank body 01.
