Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology in petroleum and chemical industries, and provides a tooling suitable for rotating heat exchanger tube bundles. Background Technology

[0002] Heat exchanger tube bundles are an important component of heat exchangers, and are industrial devices that enable heat exchange between two fluids at different temperatures through the tube walls.

[0003] Currently, heat exchanger tube bundles often need to be rotated at different angles during the production process to install related accessories. However, the traditional method is to place the heat exchanger tube bundle on a flat ground or flat workbench and use manual pry bars, jacks, shims and other tools to pry the tube sheet of the tube bundle to rotate the heat exchanger tube bundle. Using the traditional method to pry the heat exchanger tube bundle to rotate will damage the heat exchanger tube bundle tube sheet. The larger the tonnage of the heat exchanger tube bundle, the slower the prying and adjustment and the greater the physical effort required. At the same time, there is a safety risk of breakage of pry bars and other tools. Summary of the Invention

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figure 1The heat exchanger tube bundle rotation fixture shown includes a base 100, a rotating beam assembly 200, a crossbeam assembly 300, a baffle assembly 400, and a roller 500. Two sets of rotating beam assemblies 200 are provided on the base 100. A crossbeam assembly 300 is provided in front of the left side of the rotating beam assembly 200. A baffle assembly 400 is provided in front of the crossbeam assembly 300.

[0016] like Figure 2 The rotating beam assembly 200 shown includes a support beam 210, a rotating attachment 220, and a rotating wheel 221. The support beam 210 is provided with eight rotating attachments 220. Each rotating attachment 220 is provided with two rotating wheels 221. The rotating attachments 220 are electrically driven to rotate the rotating wheels 221. A roller 500 is provided above the rotating wheels 221. The rotating attachments 220, while electrically driving the rotating wheels 221 to rotate, simultaneously drive the roller 500 to rotate. When the roller 500 rotates, it drives the heat exchanger tube bundle to rotate.

[0017] like Figure 3 The beam assembly 300 shown includes an I-beam 310, a U-shaped groove 320, and a positioning rod 330; several U-shaped grooves 320 are provided above the I-beam 310; two positioning rods 330 are provided on the U-shaped grooves 320; the positioning rods 330 can be set in the U-shaped grooves 320 at different positions according to the diameter of the tube sheet.

[0018] like Figure 4 The baffle assembly 400 shown includes a support 410, a first positioning hole 411, a column 420, a second positioning hole 421, a pin 422, a baffle beam 430, and a third positioning hole 431. The support 410 has several first positioning holes 411. The column 420 is located above the support 410 and is connected to the first positioning holes 411 on the support 410. The column 420 can be positioned within the first positioning holes 411 at different locations depending on the diameter of the tube sheet. The column 420 has several second positioning holes 421, and a baffle beam 430 is located behind the column 420. The baffle beam 430 has several third positioning holes 431 and is connected to the third positioning holes 431 on the baffle beam 430 and the second positioning holes 421 on the column 420 via a pin 422.

[0019] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 The following is an explanation of the working principle of a heat exchanger tube bundle rotation fixture: A heat exchanger tube bundle rotation fixture, via a rotating attachment 220 on a rotating beam assembly 200, electrically drives a rotating wheel 221 to rotate, simultaneously rotating a drum 500. The rotation of the drum 500 causes the heat exchanger tube bundle to rotate. The fixed tube sheet end of the heat exchanger tube bundle can be placed inside the crossbeam assembly 300. When the heat exchanger tube bundle rotates to the required working angle, a positioning stop 330 is placed in the U-shaped groove 320 closest to the tube sheet to prevent the heat exchanger tube bundle from continuing to rotate due to inertia. To prevent the heat exchanger tube bundle from moving forward during rotation... A baffle assembly 400 is provided in front of the crossbeam assembly 300. The column 420 on the baffle assembly 400 can be positioned in different positions in the positioning hole 411 on the support 410 according to the diameter of the heat exchanger tube bundle and tube sheet. The baffle crossbeam 430 on the baffle assembly 400 can be adjusted to a suitable position according to the diameter of the heat exchanger tube bundle and tube sheet. After the baffle crossbeam 430 is moved to a suitable position, it is connected to the positioning hole 431 on the baffle crossbeam 430 and the positioning hole 421 on the column 420 through the pin 422.

[0020] This invention has a simple structure and low manufacturing cost. Practical industrial application has shown that it is very practical when the heat exchanger tube bundle needs to be rotated for installation accessories in petroleum and chemical heat exchanger tube bundles. It avoids damage to the heat exchanger tube bundle tube sheet and the consumption of manual labor caused by using traditional methods to pry the heat exchanger tube bundle to rotate, reduces safety risks in the production process, and improves production efficiency.
