[0002] The shell and tube condenser is a heat exchange device widely used in the industrial field. It is mainly composed of an inner tube and an outer tube to form a shell and tube structure. The hot fluid usually flows in the inner tube, while the cooling medium flows in the annular space between the outer tube and the inner tube. When the hot fluid flows in the inner tube, the heat is transferred to the external cooling medium through the inner tube wall. After the cooling medium absorbs the heat, the temperature rises, thereby cooling or condensing the hot fluid.

[0003] When processing and welding the sleeve-and-tube condenser, it is necessary to weld the contact positions of the upper circle and the lower circle of the sleeve-and-tube condenser to ensure the strength of the sleeve-and-tube condenser. The sleeve-and-tube condenser is composed of multiple circles, and welding must be performed between the upper and lower adjacent circles. Therefore, the sleeve-and-tube condenser needs to be welded multiple times during welding. The multi-circle structure means that there are many connection points that need to be welded.

The telescopic column 17 and the pressure-bearing telescopic head 18 are an integrated structure, and the structure composed of the telescopic column 17 and the pressure-bearing telescopic head 18 moves in the rectangular sleeve 16. The displacement of the contact position of the pressure-bearing telescopic head 18 and the positioning block 23 is realized by the movement of the telescopic column 17 and the pressure-bearing telescopic head 18 in the rectangular sleeve 16. When the pressure-bearing telescopic head 18 contacts the positioning block 23, it plays a blocking role. And warning effect, at the same time, after the pressure expansion head 18 and the positioning block 23 are misaligned, the pressure expansion head 18 moves to the position of the next positioning block 23, and the other central guide rod 8 is movably sleeved with an annular assembly buckle 19, and the inner wall of the annular assembly buckle 19 is fixedly installed with a positioning slide rail 20, and the positioning slide rail 20 is movably engaged in the guide slide groove 801.

[0036] A first locking bolt 902 is threadedly connected to the lifting mounting plate 9. The end of the first locking bolt 902 located inside the lifting mounting plate 9 is supported at a corresponding position on the outer wall of the center guide rod 8. Through the existence of the first locking bolt 902, the lifting mounting plate 9 can be moved on the center guide rod 8 to adapt to different installation situations.

[0037] An oblique mounting frame 24 is fixedly installed at the bottom of the lifting mounting plate 9, and an auxiliary fixing buckle 25 is fixedly installed at one end of the oblique mounting frame 24 away from the lifting mounting plate 9. The auxiliary fixing buckle 25 is movably sleeved outside the center guide rod 8, and a structure consisting of a pulley mounting frame 10 and a pulley 11 is also arranged inside the auxiliary fixing buckle 25.

[0040] The fixed mounting frame 31 is provided with a groove corresponding to the shape of the adjusting screw 29 , and the fixed mounting frame 31 and the adjusting screw 29 are clearance-matched to ensure that the lower fixed mounting frame 31 is fixedly installed, and assist the movable lifting frame 30 to move toward the fixed mounting frame 31 .

[0041] A scale bar 33 is provided between the lower mounting plate 4 and the upper mounting plate 5 for connection. The scale bar 33 is provided with scales to serve as a reference for the auxiliary lifting and lowering of the annular assembly buckle 19. A connecting strip 34 is fixedly installed on the outer wall of the annular assembly buckle 19. A buckle 35 is provided at one end of the connecting strip 34 away from the annular assembly buckle 19.

[0042] The movable lifting frame 30 and the fixed mounting frame 31 are both movably provided with a buffer pad 36, and the positions of the buffer pads 36 on the movable lifting frame 30 and the fixed mounting frame 31 correspond to each other. The presence of the buffer pad 36 reduces the pressure applied by the movable lifting frame 30 to the sleeve condenser, preventing the compressed part of the sleeve condenser from being damaged.

[0043] The buffer pad 36 is composed of three parts: a central part 3601, a protective layer 3602 and an elastic filling layer 3603. The central part 3601 is a skeleton part, which provides strength for the buffer pad 36 to ensure the strength of the installation of the buffer pad 36. At the same time, the protective layer 3602 is an outer shell layer to ensure that no sharp parts will scratch the sleeve condenser. The elastic filling layer 3603 ensures the deformation of the installation position of the buffer pad 36 to ensure the stable installation of the buffer pad 36.

[0044] The two central guide rods 8 on the lower mounting plate 4 are symmetrically arranged front to back, and the guide slots 801 on the two central guide rods 8 are oriented in the same direction.

[0045] Working principle:

[0046] Step 1: According to the number of layers of the sleeve on the sleeve condenser, adjust the number of lifting mounting plates 9 on the center guide rod 8 and the number of annular assembly buckles 19 on the other center guide rod 8. According to different processing requirements, you can choose one welding head 15 to weld the sleeve condenser at different positions multiple times, or you can choose multiple welding heads 15 to weld the sleeve condenser at different positions once. Choose according to different situations. When installing the lifting mounting plate 9 and the annular assembly buckle 19, remove the movable mounting plate 6 from the upper mounting plate 5, and set the lifting mounting plate 9 and the annular assembly buckle 19 that need to be installed on the center guide rod 8 to realize the lifting mounting plate 9 and the annular assembly buckle After the installation of the buckle 19, the lifting mounting plate 9 and the annular assembly buckle 19 are installed, the movable mounting plate 6 is reinstalled on the upper mounting plate 5 and fixed by the connecting bolts 7 to ensure the installation stability of the upper end of the center guide rod 8. The position of the annular assembly buckle 19 needs to be adjusted so that the positioning block 23 on the outer wall of the annular assembly buckle 19 is located between the upper and lower tubes of the sleeve condenser. After the position is adjusted reasonably, the T-shaped pressure plate 22 on the end of the third locking bolt 21 can be moved by rotating the third locking bolt 21. The T-shaped pressure plate 22 applies pressure to the guide groove 801 to fix the annular assembly buckle 19. The lifting mounting plate 9 is fixed by rotating the first locking bolt 902.

[0047] Step 2: The sleeve condenser to be welded is placed on the buffer pad 36 on the fixed mounting frame 31, and the sleeve condenser is supported by the buffer pad 36. The output shaft of the driving motor 32 drives the adjusting screw 29 to rotate, and the movable lifting frame 30 is driven to descend by the rotation of the adjusting screw 29. The distance between the fixed mounting frame 31 and the movable lifting frame 30 is changed by the descent of the movable lifting frame 30. The sleeve condenser is pressurized by two buffer pads 36 to fix the sleeve condenser and ensure the placement stability of the sleeve condenser. When installing multiple lifting mounting plates 9, the positions of the lifting mounting plates 9 and the annular assembly buckles 19 are made to correspond, and the lifting mounting plates 9 are fixed by rotating the first locking bolt 902. The welding head 15 is pushed to move by the piston rod of the cylinder 14, and the welding head 15 welds the position between the upper and lower pipes of the sleeve condenser. Next, when installing a lifting installation plate 9, the lifting installation plate 9 is moved up and down, so that the lifting installation plate 9 drives the rectangular sleeve 16, the telescopic column 17 and the pressure telescopic head 18 to move, and also drives other structures on the lifting installation plate 9 to move. When the pressure telescopic head 18 contacts the positioning pressure block 23, it plays a warning role, and the piston rod of the cylinder 14 pushes the welding head 15 to move, and the welding head 15 welds the position between the upper and lower pipes of the sleeve condenser, and then continues to push the lifting installation plate 9 to move. When the pressure telescopic head 18 moves, it contacts the positioning pressure block 23, and the compressed pressure telescopic head 18 and the telescopic column 17 are retracted into the rectangular sleeve 16. When the pressure telescopic head 18 and the telescopic column 17 are retracted into the rectangular sleeve 16, the spring pressure ring 26 also presses the spring 28 to drive the spring 28 to deform, so as to generate a reverse elastic force to reset the telescopic column 17 and the pressure telescopic head 18.

[0048] Step 3: When adjusting the position of the annular assembly buckle 19, the presence of the connecting strip 34 and the buckle 35 can be used to observe the position of the connecting strip 34 and the buckle 35 on the scale bar 33, which facilitates the adjustment of the position of the annular assembly buckle 19 and improves the convenience of adjusting the position of the annular assembly buckle 19.
