[0002] A heat exchanger is a device that uses the temperature difference between different fluids to transfer heat. It can transfer heat from a high-temperature fluid to a low-temperature fluid, effectively completing the heat transfer. There are many different types of heat exchangers, such as shell and tube, plate, spiral, etc., which can be used in different chemical industries.

[0003] However, the key to the manufacture of heat exchangers is the welding of the joints between the heat exchange tubes and the tube sheets, namely the sealing welding. The sealing welding can tightly connect the tube sheets and the heat exchange tubes, improve the sealing and stability of the heat exchanger, and ensure its normal operation. Therefore, through the sealing welding test, the structure and performance of the heat exchanger can be evaluated and improved, and ultimately the operating efficiency and quality level of the heat exchanger can be improved, while also improving the reliability and safety of the equipment.

[0004] However, the current sealing welding is to weld the test plate on a certain platform and then carry out the welding work. This method has the following disadvantages: when the sealing welding test plate is welded on a certain platform, when it is necessary to change the posture of the sealing welding test plate, it is necessary to knock off the original weld first, and then the posture of the test plate can be adjusted, and then the sealing welding test plate is welded on the platform again, which makes it time-consuming and laborious to remove the test plate, and at the same time increases a lot of welding work, which reduces the efficiency of the sealing welding test evaluation work.

[0027] Example

[0028] Please refer to Figure 1-3 The present embodiment provides a sealing welding test plate clamping mechanism, which includes a U-shaped platform 1, a lifting device 2 and a clamping device 3. The lifting device and the clamping device 3 are respectively arranged at the top and bottom of the U-shaped platform 1. The lifting device 2 is used to lift the sealing welding test plate 4, and the clamping device 3 is used to clamp the sealing welding test plate 4.

[0029] In this embodiment, the clamping device 3 includes a base 31, a rotating column 32, a rotating disk 33, a rotating working disk 34 and a pair of clamping components 35. The base 31 is fixed to the bottom of the U-shaped platform 1. The mass and density of the base 31 are relatively large, and it plays the role of carrying the objects above. The rotating column 32 is rotatably connected to the base 31, and the top of the rotating column 32 is connected to the rotating disk 33. It should be noted that the driving of the rotating column 32 can be driven by a motor and a belt, or by a motor and a reduction mechanism. When the rotating column 32 rotates, in order to prevent foreign objects from being drawn in between the base 31 and the rotating column 32, a protective cover 36 is installed on the top of the base 31, and the protective cover 36 is sleeved on the outside of the rotating column 32.

[0030] The rotating working disk 34 for carrying the sealing welding test plate 4 is fixed on the rotating disk 33. The rotating working disk 34 rotates synchronously with the rotating disk 33. The rotating working disk 34 is provided with a groove 341. The width of the groove 341 is greater than the thickness of the sealing welding test plate 4, and the groove depth is about 10 mm. The provision of this groove 341 facilitates the fixation of the sealing welding test plate 4 to prevent the test plate from moving or tilting. Of course, those skilled in the art can set the groove depth of the groove 341 according to actual needs.

[0031] Two slide grooves 342 are also provided on the rotating operation disk 34, and the two slide grooves 342 are symmetrically distributed about the groove 341. The clamping assembly 35 includes a sliding block 351 and a mount 352 provided on the sliding block 351, the sliding block 351 is slidably connected to the slide groove 342, the mount 352 is embedded on the sliding block 351, and the mount 352 is provided with a pair of clamping arms 3521, each clamping arm 3521 is provided with a tightening bolt 3522, when the sealing welding test plate 4 is placed in the groove 341, the left and right clamping assemblies 35 are moved until they contact the sealing welding test plate 4, so that the sealing welding test plate 4 is located between the two clamping arms 3521 of the mount 352, and then the two tightening bolts 3522 of the mount 352 are tightened, and the sealing welding test plate 4 is clamped by the two tightening bolts 3522.

[0032] In this embodiment, a stop bolt 3523 and a handle 3524 are further provided at the rear of the riding seat 352. A friction pad 3525 is provided at the bottom of the stop bolt 3523. After the clamping assembly 35 is moved into position, the stop bolt 3523 is rotated to make the stop bolt 3523 and the friction pad 3525 approach the rotating working disk 34 until the stop bolt 3523 presses against the rotating working disk 34 to prevent the clamping assembly 35 from moving. In this embodiment, the handle 3524 is provided to facilitate pushing the clamping assembly 35, and the friction pad 3525 is provided to strengthen the friction between the stop bolt 3523 and the rotating working disk 34. It should be noted that the stop bolt 3523 and the handle 3524 are both located on the side of the axis of the riding seat 352 to prevent the stop bolt 3523 from facing the slide groove 342 of the rotating working disk 34, to ensure that the stop bolt 3523 can press against the rotating working disk 34, and please refer to Figure 3 The slide groove 342 is an inverted T-shaped groove, and an inverted T-shaped block is provided at the bottom of the sliding block 351. The inverted T-shaped block slides in the inverted T-shaped groove. When the stop bolt 3523 is pressed against the rotating working disk 34, the cooperation between the inverted T-shaped block and the inverted T-shaped groove prevents the clamping assembly 35 from falling off the rotating working disk 34.

[0033] In this embodiment, the lifting device 2 includes a work plate 21 and a lifting power source for driving the work plate 21 to rise and fall. The lifting power source can be an electric hoist or other existing lifting equipment. In this embodiment, a pair of hydraulic telescopic rods 22 are used as the lifting power source. A hanging structure 23, such as a hanging ring, is also provided on the work plate 21. This hanging structure 23 plays the role of a hook to hang or connect a rope. The sealing welding test plate 4 can be hung on the hanging structure 23 with a rope. It should be noted that the entire U-shaped platform is equipped with existing switches and control devices to control the lifting and lowering of the hanging mechanism and the rotation of the rotating work disk 34.

[0034] It should be noted that a person skilled in the art can add a stability auxiliary device to the bottom of the U-shaped platform as needed, that is, add an annular base to the U-shaped platform, the base 31 and the rotating column 32 are both located at the center of the annular base, and the top of the annular base is connected to the rotating working disk 34 through a slewing bearing. The rotating working disk 34 is supported by the annular base to enhance the stability of the rotating working disk 34 and extend the service life of the rotating column 32.

[0035] This embodiment designs a clamping device 3 and a lifting device 2 so that the entire mechanism is easy to operate and disassemble, thereby improving the flexibility of use of the entire clamping mechanism, reducing the workload of staff, improving the efficiency of the sealing welding test evaluation work, and effectively improving the utilization rate of the sealing welding test plate 4 of the heat exchanger. Compared with the prior art, the utility model can save the clamping and disassembly time of the sealing welding test plate 4.
