Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling tower technology, specifically to a pipe fixing device for a chemical cooling tower. Background Technology
[0002] Chemical cooling towers are key heat exchange equipment in chemical production processes. They primarily achieve heat dissipation and cooling through heat and moisture exchange between water and air. Dry air is drawn into the cooling tower by a fan through the air inlet. High-temperature water molecules with high saturated vapor pressure flow towards the low-pressure air. The hot, humid water is sprayed into the tower from the water distribution system. When the water droplets come into contact with the air, heat transfer occurs directly between the air and water, and the pressure difference between the water vapor surface and the air causes evaporation, carrying away the latent heat of vaporization. This evaporative heat transfer achieves the purpose of cooling. The pipes in chemical cooling towers are mainly used for liquid transportation. The pipes are typically made of polyvinyl chloride, steel, or fiberglass reinforced plastic. During the installation process, the pipe positions need to be maintained by fixing devices to ensure the stability of the pipes.
[0003] CN217502822U discloses a fixing component for a chemical cooling tower pipeline, including a fixing column, an arc-shaped plate fixing unit, and a pipeline fixing unit. The fixing column has a through hole at its upper part, within which a support shaft is movably sleeved. The rear end of the support shaft is threaded and connected to a tightening block. An arc-shaped plate is fixedly connected to the front end of the support shaft. Arc-shaped plates are engaged at both ends of the arc-shaped plate, and the front ends of the two arc-shaped plates are movably connected. Circular holes are provided at both ends of the arc-shaped plate and the outer ends of the two arc-shaped plates. A fixing pipe is fixedly sleeved on the lower side of the fixing column. Two fixing blocks are fixedly connected to the outer surface of the fixing pipe, and each fixing block has a fixed shaft fixedly connected to it. This fixing component for a chemical cooling tower pipeline saves time during installation and disassembly, is not easily damaged by vibration, and is very convenient.
[0004] While existing fixed installation devices offer numerous advantages during use, they still suffer from the following drawbacks: poor adaptability to pipe sizes. Since chemical cooling towers with varying usage requirements employ pipes of different diameters, existing fixed installation devices can only accommodate pipes of a single size, impacting on-site pipe installation efficiency. Utility Model Content
[0005] To address the problems in the existing technology, this utility model provides a pipe fixing device for chemical cooling towers.
[0006] The technical solution adopted by this utility model to solve its technical problem is a pipe fixing device for a chemical cooling tower, including a sleeve, a support pipe and a first limiting rod. The support pipe is provided inside the sleeve, and a support ring is threadedly connected to one side of the outer wall of the support pipe. A positioning bolt is provided inside the support ring. The upper outer wall of the sleeve is threadedly connected to a first limiting rod distributed in a circular array. A clamping block is provided on the outside of the first limiting rod, and an anti-slip pad is glued and fixed to the end of the clamping block.
[0007] By adopting the above technical solution, the sleeve and the support pipe form a double protection. When the operator drives the sleeve to rotate circumferentially outside the support pipe, the relative rotation of the first and second limiting rods causes the clamping block to retract radially. This allows the clamping block to squeeze and clamp the outside of the pipe body through the anti-slip pad, ensuring the positional stability of the pipe body inside the support pipe. This allows the device to adapt to pipes of different diameters, ensuring the adaptability of the device, guaranteeing the fixing efficiency of the pipe body, and ensuring the firmness of the clamping of the pipe body.
[0008] Specifically, support bearings are interference-fitted to the outer walls of both sides of the support pipe, the outer ring of the support bearings is interference-fitted to the inside of the sleeve, and the pipe body is provided inside the support pipe.
[0009] By adopting the above technical solution, the support bearing supports the position of the sleeve, ensuring the stability of the sleeve's rotational position outside the support tube.
[0010] Specifically, rhomboid blocks are welded to the outer walls of both sides of the sleeve, and two rhomboid blocks are located on the upper and lower sides of the support ring.
[0011] By adopting the above technical solution, the shape of the diamond block can be adapted to the size of the wrench, so that the operator can rotate the diamond block and the sleeve by the wrench to ensure the smooth rotation of the sleeve.
[0012] Specifically, the outer wall of the support tube is equipped with a circular array of fixed seats, the outer wall of the fixed seats is provided with threaded holes, and the positioning bolts pass through the end of the support ring and are threaded into the inside of the threaded holes.
[0013] By adopting the above technical solution, the support ring is connected to the threaded hole of the fixing seat on the outer wall of the support pipe through the positioning bolt, which can lock the sleeve in the position outside the support pipe. This can limit the use angle of the clamping block and ensure the clamping stability of the clamping block on the pipe body. The multi-point fixing seat can limit the rotation angle of the sleeve. Since the size of the pipe body is in accordance with national standards, in actual use, by adjusting the layout of the fixing seat, it can be ensured that the use angle of the clamping block can adapt to pipe bodies of different sizes.
[0014] Specifically, a fixing corner piece is screwed to one side of the outer wall of the support tube, the fixing corner piece has mounting holes arranged in a rectangular array on its outer wall, and the sleeve has a slot for receiving the fixing corner piece on its outer wall.
[0015] By adopting the above technical solution, the staff can fix the fixing corner piece with external screws, which can fix the fixing corner piece at the upper end of the use position, thereby restricting the position of the support tube and the sleeve. The slot can accommodate the fixing corner piece and prevent the rotation of the sleeve from being blocked by the support tube.
[0016] Specifically, the upper outer wall of the support tube is threaded with a second limiting rod distributed in a circular array, and the clamping block has a guide groove inside, with the second limiting rod inside the guide groove.
[0017] By adopting the above technical solution, when the support pipe rotates outside the sleeve, the first limiting rod and the second limiting rod rotate relative to each other, so that the clamping block can rotate around the first limiting rod through the guide groove, so that the clamping block moves to the outside of the pipe body and realizes the clamping block clamping and fixing the pipe body, ensuring the stable fixing of the pipe body.
[0018] Specifically, a limit bearing is interference-fitted inside the clamping block, and the first limit rod is interference-fitted to the inner ring of the limit bearing.
[0019] By adopting the above technical solution, the limiting bearing enables the clamping block to rotate outside the first limiting rod when the first limiting rod is adjusted by rotating with the sleeve, so that the clamping block can move radially.
[0020] The beneficial effects of this utility model are:
[0021] The pipe fixing device for a chemical cooling tower described in this utility model can drive the clamping block to retract radially, so that the clamping block squeezes and clamps the outside of the pipe body through the anti-slip pad, ensuring the positional stability of the pipe body inside the support pipe. This allows it to adapt to pipes of different diameters, ensuring the adaptability of the device, guaranteeing the fixing efficiency of the pipe body, and ensuring the firmness of the clamping of the pipe body.
[0022] The pipe fixing device for a chemical cooling tower described in this utility model can lock the sleeve in the position outside the support pipe, thereby limiting the use angle of the clamping block and ensuring the stability of the clamping block on the pipe body. The multi-point fixing seat can limit the rotation angle of the sleeve. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pipe fixing device for a chemical cooling tower according to the present invention includes a sleeve 1, a support pipe 2, and a first limiting rod 15. The support pipe 2 is provided inside the sleeve 1. A support ring 12 is threadedly connected to one side of the outer wall of the support pipe 2. A positioning bolt 13 is provided inside the support ring 12. The first limiting rod 15 distributed in a circular array is threadedly connected to the upper outer wall of the sleeve 1. A clamping block 16 is provided on the outside of the first limiting rod 15. An anti-slip pad 17 is glued and fixed to the end of the clamping block 16.
[0031] During use, the sleeve 1 and the support tube 2 form a double protection. When the operator drives the sleeve 1 to rotate circumferentially outside the support tube 2, the relative rotation of the first limiting rod 15 and the second limiting rod 23 causes the clamping block 16 to retract radially. This causes the clamping block 16 to squeeze and clamp the outside of the pipe body 11 through the anti-slip pad 17, ensuring the positional stability of the pipe body 11 inside the support tube 2. This allows the device to adapt to pipes of different diameters, ensuring the adaptability of the device, guaranteeing the fixing efficiency of the pipe body 11, and ensuring the clamping firmness of the pipe body 11.
[0032] To maintain the rotational position, for example, such as Figure 2As shown, support bearings 22 are interference-fitted on both outer walls of the support pipe 2, and the outer ring of the support bearing 22 is interference-fitted inside the sleeve 1. The pipe body 11 is provided inside the support pipe 2.
[0033] During use, the support bearing 22 supports the position of the sleeve 1 to ensure that the rotational position of the sleeve 1 outside the support tube 2 is stable.
[0034] To drive rotation, for example, such as Figure 3 As shown, rhomboid blocks 14 are welded to the outer walls of both sides of the sleeve 1, and the two rhomboid blocks 14 are located on the upper and lower sides of the support ring 12.
[0035] When in use, the shape of the diamond block 14 can be adapted to the size of the wrench, so that the operator can rotate the diamond block 14 and the sleeve 1 by the wrench to ensure the smooth rotation of the sleeve 1.
[0036] To fix the usage location, for example, such as Figure 3 As shown, the outer wall of the support tube 2 is equipped with a circular array of fixed seats 24. The outer wall of the fixed seat 24 has threaded holes, and the positioning bolt 13 passes through the end of the support ring 12 and is threaded into the inside of the threaded holes.
[0037] In use, the support ring 12 is connected to the threaded hole of the fixing seat 24 on the outer wall of the support pipe 2 through the positioning bolt 13, which can lock the sleeve 1 in the position outside the support pipe 2, thereby limiting the use angle of the clamping block 16 and ensuring the clamping stability of the clamping block 16 on the pipe body 11. The multi-point fixing seat 24 can limit the rotation angle of the sleeve 1. Since the size of the pipe body 11 is in accordance with national standards, in actual use, by adjusting the layout of the fixing seat 24, it can be ensured that the use angle of the clamping block 16 can adapt to pipe bodies 11 of different sizes.
[0038] To maintain the usage location, for example, such as Figure 2 As shown, a fixing corner piece 21 is screwed to one side of the outer wall of the support tube 2. The fixing corner piece 21 has mounting holes arranged in a rectangular array on its outer wall. The sleeve 1 has a slot for receiving the fixing corner piece 21 on its outer wall.
[0039] When in use, the staff can fix the fixing corner piece 21 with external screws, which can fix the fixing corner piece 21 at the upper end of the use position, thereby restricting the position of the support tube 2 and the sleeve 1. The slot can accommodate the fixing corner piece 21, so as to prevent the rotation of the sleeve 1 from being blocked by the support tube 2.
[0040] To drive rotation, for example, such as Figure 4As shown, the upper outer wall of the support tube 2 is threaded with a second limiting rod 23 distributed in a circular array, and the clamping block 16 has a guide groove inside, with the second limiting rod 23 located inside the guide groove.
[0041] When the support tube 2 rotates outside the sleeve 1, the first limiting rod 15 and the second limiting rod 23 rotate relative to each other, so that the clamping block 16 can rotate around the first limiting rod 15 through the guide groove, so that the clamping block 16 moves to the outside of the pipe body 11 and clamps and fixes the pipe body 11, ensuring that the pipe body 11 is firmly fixed.
[0042] To maintain a stable rotational position, for example, such as Figure 4 As shown, the clamping block 16 is internally interference-fitted with a limit bearing 18, and the first limit rod 15 is interference-fitted with the inner ring of the limit bearing 18.
[0043] In use, the limit bearing 18 allows the first limit rod 15 to rotate and adjust in accordance with the sleeve 1, and the clamping block 16 can rotate outside the first limit rod 15, so that the clamping block 16 can move radially.
[0044] In use, the support tube 2 is fixed in the preset installation position by means of the fixing corner piece 21 and the mounting hole, and the pipe body 11 to be fixed is inserted into the support tube 2 so that it is in the center area of the support tube 2.
[0045] The staff uses a wrench to engage the diamond-shaped blocks 14 on both sides of the sleeve 1 and rotates the sleeve 1. As the sleeve 1 rotates, the first limiting rod 15 at its upper end rotates relative to the second limiting rod 23 on the support pipe 2. Under the action of the limiting bearing 18, the clamping block 16 slides along the second limiting rod 23 through the guide groove, and at the same time retracts radially along the first limiting rod 15. Finally, it squeezes the outside of the pipe body 11 through the anti-slip pad 17 at the end, thus completing the clamping and fixing of the pipe body 11.
[0046] After the clamping block 16 firmly clamps the pipe body 11, the positioning bolt 13 on the support ring 12 passes through the support ring 12 and is threaded into the threaded hole of the fixing seat 24 at the corresponding position on the outer wall of the support pipe 2, thereby locking the relative position of the sleeve 1 and the support pipe 2 and ensuring the stability of the clamping angle.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
