[0006] To achieve the above objectives, this utility model provides the following technical solution: a shell-and-tube heat exchanger support assembly, comprising a base plate and an adjustment mechanism, wherein the adjustment mechanism includes a crank handle, side plates are fixedly connected to both sides of the top of the base plate, and bidirectional threaded rods are rotatably mounted on the two sets of side plates. The crank handle is fixedly sleeved on the right end of the bidirectional threaded rods, and two sets of supports are symmetrically screwed onto the bidirectional threaded rods. Two sets of sliding grooves are symmetrically opened at the bottom ends of the two sets of supports, and two sets of slide rails are symmetrically fixedly connected to the top of the base plate. The left and right ends of the slide rails are respectively fixedly connected to the inner sides of the two sets of side plates, and the supports are slidably mounted on the two sets of slide rails through the cooperation of the sliding grooves. Each component is equipped with a fixing mechanism, which includes a fixing seat and a bracket. The fixing seat is fixedly connected to the upper rear end of the bracket, and a rotating shaft is rotatably mounted on the fixing seat. A horizontal plate is fixedly connected to the top of the rotating shaft. The bracket is fixedly connected to the front end of the bracket, and a slot is provided on the top inner side of the bracket. A pin is inserted into the top of the bracket, and the front end of the horizontal plate is inserted into the slot. A pin hole is provided on the front top of the horizontal plate, and the pin passes through the slot and is inserted into the pin hole. A threaded rod is screwed into the middle of the horizontal plate, and a handwheel is fixedly connected to the top of the threaded rod. A clamping seat is rotatably connected to the bottom end of the threaded rod. Two sets of guide posts are symmetrically fixedly connected to the top of the clamping seat, and the two sets of guide posts are slidably mounted on the horizontal plate.

This allows the support, along with the fixing mechanism, to adjust its position. After adjusting the support to the appropriate position, the pin is pulled out, and the horizontal plate is rotated to the rear of the support. The shell-and-tube heat exchanger to be installed is then placed... The heat exchanger is placed on two sets of supports, then the horizontal plate is inserted into the slot, and the pin is inserted into the pin hole to fix the position of the horizontal plate. By turning the threaded rod with the handwheel, the threaded rod pushes the clamping seat downward, thereby pressing the clamping seat onto the shell-and-tube heat exchanger, completing the support and fixation of the shell-and-tube heat exchanger. By adjusting the position of the supports, the heat exchanger can be supported and fixed in an appropriate position, thus allowing adjustment according to the length of the shell-and-tube heat exchanger, improving the support and fixation effect of the shell-and-tube heat exchanger, and improving practicality.

Detailed Implementation
[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0017] Example
[0018] Please see Figures 1-4This utility model discloses a shell-and-tube heat exchanger support assembly, comprising a base plate 1 and a crank handle 2. Side plates 3 are fixedly connected to both sides of the top of the base plate 1. Two sets of bidirectional threaded rods 4 are rotatably mounted on the two sets of side plates 3. The crank handle 2 is fixedly sleeved on the right end of the bidirectional threaded rods 4. Two sets of supports 5 are symmetrically screwed onto the bidirectional threaded rods 4. Two sets of sliding grooves 6 are symmetrically opened at the bottom of each set of supports 5. Two sets of slide rails 7 are symmetrically fixedly connected to the top of the base plate 1. The left and right ends of the slide rails 7 are respectively fixedly connected to the inner sides of the two sets of side plates 3. The supports 5 are slidably mounted on the two sets of slide rails 7 through the cooperation of the sliding grooves 6. Each set of supports 5 is equipped with a fixing mechanism. The fixing mechanism includes a fixed base 8 and a bracket 11. The fixed base 8 is fixedly connected to the upper rear end of the support 5. A rotating shaft 9 is rotatably mounted on the fixed base 8. A horizontal plate 10 is fixedly connected to the top of the rotating shaft 9. The bracket 11 is fixedly connected to the front end of the support 5. A slot 12 is provided on the top inner side of the bracket 11. A pin 18 is inserted into the top of the bracket 11. The front end of the horizontal plate 10 is inserted into the slot 12. A pin hole is provided on the front top of the horizontal plate 10. The pin 18 passes through the slot 12 and is inserted into the pin hole. A threaded rod 13 is screwed into the middle of the horizontal plate 10. A handwheel 14 is fixedly connected to the top of the threaded rod 13. A clamp is rotatably connected to the bottom end of the threaded rod 13. The support 15 has two sets of guide posts 16 symmetrically fixedly connected to its top. The two sets of guide posts 16 are slidably mounted on the horizontal plate 10. In use, the position of the support 5 is adjusted according to the length of the shell-and-tube heat exchanger. By rotating the double-threaded rod 4 with the crank handle 2, the double-threaded rod 4 drives the support 5 to slide along the slide rail 7. Rotating the double-threaded rod 4 clockwise causes the support 5 to slide outward, and rotating the double-threaded rod 4 counterclockwise causes the support 5 to slide inward. This allows the support 5, along with the fixing mechanism, to adjust its position. After adjusting the support 5 to the appropriate position, the pin 18 is pulled out, and the horizontal plate 10 is rotated to the support 5. Behind, place the shell-and-tube heat exchanger to be installed on the two sets of supports 5, then insert the horizontal plate 10 into the slot 12 and insert the pin 18 into the pin hole to fix the position of the horizontal plate 10. Rotate the threaded rod 13 by handwheel 14 to push the clamping seat 15 downward, thereby pressing the clamping seat 15 onto the shell-and-tube heat exchanger, thus completing the support and fixation of the shell-and-tube heat exchanger. By adjusting the position of the supports 5, the shell-and-tube heat exchanger can be supported and fixed in an appropriate position, so as to adjust according to the length of the shell-and-tube heat exchanger, improve the support and fixation effect of the shell-and-tube heat exchanger, and improve practicality.
[0019] Both sets of support 5 have fastening pads 17 fixedly connected to the top arc surface and the bottom arc surface of clamping seat 15. By setting the fastening pads 17, the support 5 and clamping seat 15 can be more tightly and reliably supported and fixed when supporting and fixing the shell and tube heat exchanger.
[0020] The cross-sections of both the slide groove 6 and the slide rail 7 are isosceles trapezoids; by setting the isosceles trapezoids, the slide groove 6 and the slide rail 7 can be matched more stably, and the smoothness of the sliding of the support 5 can be improved.
[0021] The base plate 1 has countersunk holes 19 at each of its four corners; by setting the countersunk holes 19, the base plate 1 can be easily fixed and installed with bolts.
[0022] The working principle of this utility model is as follows: During use, the position of the support 5 is adjusted according to the length of the shell-and-tube heat exchanger. The double-threaded rod 4 is rotated by the crank handle 2, causing the support 5 to slide along the slide rail 7. Rotating the double-threaded rod 4 clockwise causes the support 5 to slide outwards, and rotating it counterclockwise causes it to slide inwards. This allows the support 5, along with the fixing mechanism, to adjust its position. After adjusting the support 5 to the appropriate position, the pin 18 is pulled out, and the horizontal plate 10 is rotated to the rear of the support 5. The shell-and-tube heat exchanger to be installed is placed on the two sets of supports 5. The horizontal plate 10 is then inserted into the slot 12, and the pin 18 is inserted into the pin hole to fix the position of the horizontal plate 10. The threaded rod 13 is rotated by the handwheel 14, causing it to push the clamping seat 15 downwards, thus pressing the clamping seat 15 onto the shell-and-tube heat exchanger and completing the support and fixing of the shell-and-tube heat exchanger.
[0023] The shell-and-tube heat exchanger support assembly of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired beneficial effect can be implemented. The pin 18 of the shell-and-tube heat exchanger support assembly of this utility model is purchased commercially. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.
[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
