They are mainly used for full contact and mass and heat transfer between gas-liquid or liquid-liquid phases. They are widely used in chemical unit operations such as distillation, purification, absorption, and rectification. They are key equipment for achieving mass and heat transfer between gas-liquid or liquid-liquid phases. During the installation of chemical towers, in order to prevent tilting, auxiliary fixing equipment is usually required.

[0003] According to the patent number CN 210032852 U disclosed in a chemical tower installation and fixing auxiliary device, the chemical tower installation and fixing auxiliary device adopts a structural design of a stand, a base plate and a hydraulic cylinder, which can support the chemical tower and adjust the support angle by the telescopic movement of the hydraulic cylinder, so that the chemical tower can be adjusted to the right position more conveniently. In the process of realizing the utility model, the inventor found that there are at least the following problems in the prior art that have not been solved: although the problem of tilting and straightening is solved by setting a hydraulic cylinder to push the chemical tower, the tilting direction of the chemical tower is not certain during the installation process. Therefore, it may not be possible to align the tilting direction exactly when straightening, resulting in a new tilt when straightening, thereby affecting practicality. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a chemical tower installation and fixing auxiliary device to solve the technical problem that in the current installation process, the tilt direction of the chemical tower is uncertain, so when straightening it may not be exactly aligned with the tilt direction, resulting in new tilt when straightening, thereby affecting practicality.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: a chemical tower installation and fixing auxiliary device is designed, including a semi-ring plate, a push plate and a chemical tower body, the top of the semi-ring plate is provided with a slide rail, the inner side of the slide rail is slidably connected to a slider, the top of the slider is fixedly connected to a pad, the top of the pad is fixedly connected to a support frame, the support frame is fixedly connected to a hydraulic cylinder at an upper position on the surface of the side away from the chemical tower body, the telescopic end of the hydraulic cylinder passes through the surface of the support frame and is fixedly connected to the mounting groove, the side wall protrusion of the push plate is movably connected to the mounting groove through a rotating shaft, and the inner edge of the top of the semi-ring plate is provided with an angle line; the side walls of the support frame on the upper and lower sides of the hydraulic cylinder are respectively threadedly connected with an upper screw and a lower screw, and the upper and lower screws are fixedly connected with a stop block at one end close to the chemical tower body.

[0006] Preferably, outer edges at both ends of the semi-annular plate are fixedly connected with connecting plates, and connecting bolts are threadedly connected to the side walls of the connecting plates.

[0007] Preferably, a telescopic rod is fixedly connected to the center of the inner side wall of the semi-annular plate, and a fitting plate is fixedly connected to one end of the telescopic rod facing the chemical tower body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model can support the chemical tower body through the angle line, support frame, hydraulic cylinder, mounting groove, rotating shaft and push plate. The position of the slider is adjusted according to the scale of the angle line. After the slider slides to the appropriate position, the hydraulic cylinder is started to push the push plate toward the chemical tower body.

DETAILED DESCRIPTION

[0019] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A chemical tower installation and fixing auxiliary device, see Figures 1 to 3 , including a semi-ring plate 1, a push plate 10 and a chemical tower body 16, a slide rail 2 is provided at the top of the semi-ring plate 1, and a slider 3 is slidably connected to the inner side of the slide rail 2, and the top of the slider 3 is fixedly connected to a pad 4, and the top of the pad 4 is fixedly connected to a support frame 6. The support frame 6 is fixedly connected to a hydraulic cylinder 7 at an upper position on the surface of the side away from the chemical tower body 16. The telescopic end of the hydraulic cylinder 7 passes through the surface of the support frame 6 and is fixedly connected to the mounting groove 8. The side wall protrusion of the push plate 10 is movably connected to the mounting groove 8 through the rotating shaft 9. The inner edge of the top of the semi-ring plate 1 is provided with an angle line 17. The position of the slider 3 is adjusted according to the scale of the angle line 17. The hydraulic cylinder 7 is started to push the push plate 10 toward the chemical tower body 16, pushing the chemical tower body 16, thereby supporting and straightening the chemical tower body 16, and providing multiple pairs of sliders 3 to constrain and limit the chemical tower body 16 at multiple angles, thereby improving the stability of the chemical tower body 16.

[0021] At the same time, the side walls of the support frame 6 on the upper and lower sides of the hydraulic cylinder 7 are respectively threadedly connected with an upper screw 11 and a lower screw 12. The upper screw 11 and the lower screw 12 are fixedly connected to a stop block 13 at one end close to the chemical tower body 16. The lower screw 12 on the support frame 6 on the tilted side is twisted to move the stop block 13 toward the push plate 10. When the push plate 10 gradually becomes vertical following the chemical tower body 16, it finally contacts the stop block 13 in a vertical state, restricting the push plate 10 and keeping it in a vertical state, thereby avoiding new tilt caused by over-positioning during the straightening process.

[0022] For details, see Figure 2 The outer edges of both ends of the semi-ring plate 1 are fixedly connected with a connecting plate 101, and the side wall of the connecting plate 101 is threaded with a connecting bolt 102. After the connecting bolt 102 is tightened, the two semi-ring plates 1 will be connected together, and a complete ring will be formed at this time. It is set on the outside of the chemical tower body 16 to facilitate the sliding of the slider 3.

[0023] For further information, see Figure 1 A telescopic rod 14 is fixedly connected to the center of the inner wall of the semi-ring plate 1, and a fitting plate 15 is fixedly connected to one end of the telescopic rod 14 facing the chemical tower body 16. The fitting plate 15 can contact the surface of the chemical tower body 16. The length of the telescopic rod 14 can be adjusted, and the surface of the telescopic rod 14 is provided with a scale and a bolt for fixing, which can facilitate the chemical tower body 16 to be located in the center of the two semi-ring plates 1 when installing the semi-ring plate 1, thereby facilitating subsequent straightening.

[0024] It is worth noting that, see Figure 1 The side wall of the pad 4 is slidably connected with a measuring rod 5, and a scale line 501 is provided on the top of the measuring rod 5. The direction of the measuring rod 5 is consistent with the telescopic direction of the hydraulic cylinder 7. The measuring rod 5 can slide horizontally, and a scale line 501 is provided on its surface. The measuring rods 5 on both sides slide toward the chemical tower body 16. After contacting the chemical tower body 16, the scale readings on both sides can be observed. According to the difference in the readings, the direction of the chemical tower body 16 when it is slightly tilted can be known, which is convenient for adjusting the straightening position.

[0025] It is worth noting that see Figure 1 A soft pad 1001 is fixedly connected to the surface of the push plate 10 facing the chemical tower body 16. The soft pad 1001 can provide buffering when the push plate 10 contacts the chemical tower body 16 and pushes the chemical tower body 16.

[0026] It is worth mentioning that see Figure 3The upper screw rod 11 and the lower screw rod 12 are parallel to the ground, and the surfaces of the upper screw rod 11 and the lower screw rod 12 are threadedly connected with a fixing nut 18. When the fixing nut 18 is twisted into contact with the support frame 6, the screw rod can be fixed to prevent it from rotating freely. When the upper screw rod 11 and the lower screw rod 12 are fully twisted into the support frame 6, the stop block 13 at the other end can just fit into the side wall of the push plate 10 in the vertical state. Based on this point, the push plate 10 can be limited from the other side when straightening to avoid new tilt caused by over-correction.

[0027] It is worth noting that, see Figure 1 The end of the measuring rod 5 away from the chemical tower body 16 is fixedly connected to the limiting block 502. The limiting block 502 can limit the outer end of the measuring rod 5 to prevent it from completely sliding into the pad 4.

[0028] Working principle: Splice two semi-ring plates 1 together and fix them with connecting bolts 102. Before splicing, slide several pairs of sliders 3 into the slide rail 2. The sliders 3 slide on the inside of the slide rail 2. Adjust the position of the sliders 3 according to the scale of the angle line 17. After the sliders 3 slide to the appropriate position, the hydraulic cylinder 7 is started to push the push plate 10 toward the chemical tower body 16. Under the action of the rotating shaft 9 of the mounting groove 8, the push plate 10 can be tilted to fit the surface of the chemical tower body 16 and push the chemical tower body 16, thereby supporting and straightening the chemical tower body 16. The two sliders 3 are a pair, which support and straighten from both sides respectively, and multiple pairs of sliders 3 can be set to straighten the chemical tower body 16 at multiple angles. The chemical tower body 16 is constrained and limited, which improves the stability of the chemical tower body 16, is more convenient to operate and more practical. During the straightening process, the lower screw 12 on the tilted side support frame 6 can be twisted to move the stop block 13 toward the push plate 10. When the push plate 10 gradually becomes vertical following the chemical tower body 16, it will eventually contact the stop block 13 in a vertical state. At this time, the chemical tower body 16 is consistent with the push plate 10 and is perpendicular to the ground, thereby avoiding new tilting caused by over-supporting during the straightening process, thereby improving the efficiency and stability of the straightening. After straightening, tightening all the upper screws 11 and the lower screws 12 can support the push plate 10 and release the pressure of the hydraulic cylinder 7.
