[0002] In large-scale building structures such as cooling towers, steel tube concrete X-shaped diagonal pillars are key supporting components and are crucial to ensuring the safety and stability of buildings. Traditional diagonal pillar installation usually adopts a fixed connection method. Although this connection method can provide a certain support strength, it has some obvious limitations in practical applications. For example, it is difficult to achieve precise height adjustment under complex terrain conditions, which affects the stability and safety of the entire structure; in addition, the installation and disassembly process of the traditional connection method is relatively cumbersome and requires a lot of manpower and time costs, which not only reduces construction efficiency but also is not conducive to later maintenance.

[0003] In recent years, with the development of engineering technology, detachable diagonal support connectors have emerged. They improve the shortcomings of traditional fixed connection methods by introducing pre-tightening mechanisms and pressure regulating mechanisms. However, existing detachable connectors still have some problems: the design of the pre-tightening mechanism is often not flexible enough to achieve fast and reliable positioning and fixing; the adjustment accuracy of the pressure regulating mechanism is not high, and it cannot adapt well to the changes in different height requirements.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention realizes rapid pre-positioning and fixed installation through a pre-tightening mechanism between the clamping plate and the pulling plate. The first positioning groove and the second positioning groove on the clamping plate cooperate with the pulling plate. The positioning ring is inserted into the first mounting hole for pre-fixing under the action of the first spring, and the subsequent installation of the fixing bolt is also very convenient, which greatly improves the efficiency of on-site installation and is particularly suitable for construction scenarios of large-scale building structures such as cooling towers, reducing construction time and labor costs. The positioning ring in the pre-tightening mechanism is designed to cooperate with the fixing bolt, such as the rib groove on the positioning ring and the reinforced rib of the fixing bolt slidingly cooperate to evenly transmit the pressure to the clamping plate, effectively improving the service life of the pre-tightening mechanism, reducing the risk of damage to components due to uneven force, thereby ensuring the reliability of the connection of the entire X-shaped oblique support. The limiting plate on the clamping plate and the second sliding hole are designed to cooperate with the ratchet ring, so that the positioning ring will rotate counterclockwise by a certain angle during each installation process, so that the positioning ring is evenly worn at each position after multiple installations, avoiding the problem of component failure caused by local excessive wear, extending the service life of the positioning ring, reducing the frequency of equipment maintenance and replacement, and reducing the long-term use cost.

[0025] 2. The height of the support column of the present invention can be accurately adjusted by a pressure regulating mechanism. The boosting component pumps hydraulic oil into the first hydraulic chamber through structures such as cams and connecting rods, thereby realizing the raising of the support column to adapt to different installation terrains and height requirements of building structures; the pressure reducing component can cause the hydraulic oil to flow back and lower the support column. This height adjustment function can ensure that the X-shaped inclined support column can achieve the best supporting effect under various complex working conditions, and ensure the stability and safety of the cooling tower structure. The worm gear transmission structure in the pressure regulating mechanism effectively reduces the transmission resistance, making the adjustment process smoother, while also reducing the wear of components and improving the durability of the equipment. The valve block on the return pipe is elastically slidably connected to the valve pipe through a second spring, and is matched with a limiting ridge and a limiting groove, which can not only facilitate operation, but also effectively prevent the support column from shrinking due to accidental touch, further enhancing the reliability of equipment operation.

DETAILED DESCRIPTION

[0041] Example 1

[0042] See also Figure 1-Figure 14 The cooling tower steel tube concrete X-shaped inclined support detachable component includes an X-shaped inclined support 3, a pull plate 4, a steel ring beam 6, a clamping plate 1 and a support column 2, a pre-tightening mechanism 7 is arranged on the clamping plate 1, and a pressure regulating mechanism 8 is arranged on the support column 2;

[0043] The pull plate 4 is fixedly installed at the intersection of the X-shaped oblique support column 3, the steel ring beam 6 is fixedly installed on the top of the X-shaped oblique support column 3, the clamping plate 1 is detachably installed on the pull plate 4, and the clamping plate 1 is movably installed on the top of the support column 2 through a pin shaft;

[0044] The pull plate 4 is provided with a first mounting hole 5, the clamping plate 1 is provided with a first positioning groove 102 and a second positioning groove 104 corresponding to the shape of the pull plate 4, the side of the clamping plate 1 is provided with a second mounting hole 101 corresponding to the position of the first mounting hole 5, the pre-tightening mechanism 7 includes a positioning ring 701, a first spring 702, a fixing bolt 703 and a nut 704, and the pre-tightening mechanism 7 is installed in the second mounting hole 101;

[0045] The support column 2 includes a hydraulic rod 201 and a hydraulic cylinder 202. The hydraulic cylinder 202 is provided with a first hydraulic chamber 2021, an equipment chamber 2022, and a second hydraulic chamber 2023. The second hydraulic chamber 2023 is provided with a piston plate 2024.

[0046] The pressure regulating mechanism 8 includes a pressure boosting component 801 and a pressure reducing component 802. The pressure boosting component 801 includes a piston sleeve 8011, a piston head 8012, a connecting rod 8013, a cam 8014, a first adjusting shaft 8015, a knob 8016, a worm gear 8018, a worm 8017 and a first rotating shaft 8019. The pressure reducing component 802 includes a return pipe 8021, a valve pipe 8022, a valve block 8023 and a second spring 8024. The pressure regulating mechanism 8 is installed in the equipment room 2022 to regulate the pressure of the first hydraulic chamber 2021.

[0047] When the clamping plate 1 is sleeved on the pulling plate 4, the pulling plate 4 contacts and squeezes the spherical structure of the positioning ring 701, causing the positioning ring 701 to slide into the second mounting hole 101, compressing the first spring 702. The first spring 702 stores elastic potential energy. When the positioning ring 701 reaches the position of the first mounting hole 5, the first spring 702 releases the potential energy and bounces the positioning ring 701 into the first mounting hole 5, thereby achieving the initial positioning of the clamping plate 1 on the pulling plate 4, facilitating the subsequent installation of the fixing bolts 703, and at the same time ensuring the tightness and stability of the connection between the clamping plate 1 and the pulling plate 4, thereby preventing To prevent the displacement or loosening of the two during use, the knob 8016 is turned to drive the cam 8014 on the first rotating shaft 8019 to rotate through the worm gear 8018 and the worm 8017. The rotation of the cam 8014 is converted into an up and down reciprocating motion of the connecting rod 8013, which in turn drives the piston head 8012 to move up and down in the piston sleeve 8011. When the piston head 8012 moves downward, negative pressure is generated in the piston sleeve 8011. Under the action of the first one-way valve 80113, the hydraulic oil in the second hydraulic chamber 2023 is sucked into the piston sleeve 8011. 011; When the piston head 8012 moves upward, under the action of the second one-way valve 80114, the hydraulic oil is pressed into the first hydraulic chamber 2021, pushing the hydraulic rod 201 to extend upward, so as to raise the support column 2, thereby realizing the precise control of the height of the support column 2. When the height of the support column 2 needs to be lowered, the adjustment plate 80233 on the valve block 8023 is operated to align the valve hole 80231 with the return pipe 8021. At this time, the first hydraulic chamber 2021 and the second hydraulic chamber 2023 are connected through the return pipe 8021. The hydraulic oil pressure in the hydraulic chamber 2021 is higher than that in the second hydraulic chamber 2023. Under the action of the pressure difference, the hydraulic oil flows back from the first hydraulic chamber 2021 to the second hydraulic chamber 2023 through the return pipe 8021, causing the height of the support column 2 to drop. The cooperation of the second spring 8024 and the limiting ridge 80234 and the limiting groove 80221 can not only conveniently control the opening and closing of the valve hole 80231, but also prevent the support column 2 from accidentally dropping due to accidental touching of the adjustment plate 80233 during normal use, thereby ensuring the safety and stability of the equipment operation.

[0048] Furthermore, a first sliding hole 1011 and a second sliding hole 1012 are provided in the second mounting hole 101, a positioning ring 701 is installed in the second mounting hole 101 and is slidably connected to the clamping plate 1, a limiting plate 7011 is provided on the outer end surface of the positioning ring 701 and is slidably matched with the second sliding hole 1012, the first spring 702 is sleeved on the positioning ring 701, a spring positioning groove 7015 is provided on the positioning ring 701 and is matched with the first spring 702, and the end of the positioning ring 701 close to the second positioning groove 104 is a spherical structure.

[0049] When the splint 1 is sleeved on the pull plate 4, the pull plate 4 can squeeze the positioning ring 701, causing it to squeeze the first spring 702 to contract inward, thereby storing energy. When the positioning ring 701 reaches the first mounting hole 5, the positioning ring 701 is inserted into the first mounting hole 5 under the resetting action of the first spring 702, completing the initial positioning of the splint 1, thereby facilitating the installation of the fixing bolt 703. The positioning ring 701 is prevented from falling off by the cooperation of the limit plate 7011 and the second mounting hole 101, and the spring positioning groove 7015 is used to prevent the spring from deviating in the first sliding hole 1011.

[0050] Furthermore, a first ratchet ring 7012 and a second ratchet ring 7013 are provided on the front and rear sides of the limiting plate 7011, and the first ratchet ring 7012 and the second ratchet ring 7013 are mirror-imaged on the front and rear sides of the limiting plate 7011, and the ratchets on the first ratchet ring 7012 and the second ratchet ring 7013 are mirror-symmetric, and a fourth ratchet ring 1014 cooperating with the second ratchet ring 7013 is provided on the front end surface of the second sliding hole 1012, and a third ratchet ring 1013 cooperating with the first ratchet ring 7012 is provided on the rear end of the second sliding hole 1012, and the ratchets on the third ratchet ring 1013 and the fourth ratchet ring 1014 are staggered.

[0051] After the splint 1 is installed on the X-shaped oblique support 3, it needs to be disassembled for the next use. Therefore, each time the splint 1 is installed, the limit plate 7011 slides back and forth once in the second sliding hole 1012, so that the first ratchet ring 7012 and the third ratchet cooperate once, and the second ratchet ring 7013 and the fourth ratchet ring 1014 cooperate once. When the positioning ring 701 squeezes the first spring 702 to shrink into the second installation hole 101, under the cooperation of the second ratchet ring 7013 and the fourth ratchet ring 1014, The positioning ring 701 rotates counterclockwise by a certain angle. When the positioning ring 701 pops out under the action of the first spring 702, the first ratchet ring 7012 and the third ratchet ring 1013 cooperate. Since the third ratchet ring 1013 and the fourth ratchet ring 1014 are staggered, the positioning ring 701 rotates counterclockwise by a certain angle again. Each time the positioning ring 701 is installed, it rotates counterclockwise by a certain angle. Therefore, when the positioning ring 701 is installed multiple times and used, each position is evenly worn, thereby improving the service life of the equipment.

[0052] Furthermore, a reinforcing convex rib 7031 is provided in the middle of the surface of the fixing bolt 703 , and a rib groove 7014 which is slidably matched with the reinforcing convex rib 7031 is provided on the positioning ring 701 .

[0053] By strengthening the convex rib 7031 and increasing the middle diameter of the fixing bolt 703, it is avoided that only the edge of the positioning ring 701 is under pressure after installation, and the pressure is evenly transmitted to the clamping plate 1 through the fixing bolt 703, thereby improving the service life of the preload mechanism 7.

[0054] Furthermore, an oil suction pipe 80111 communicating with the second hydraulic chamber 2023 is provided at the top of the side end surface of the piston sleeve 8011, and a first one-way valve 80113 is provided on the oil suction pipe 80111. An oil discharge pipe 80112 communicating with the first hydraulic chamber 2021 is provided at the top of the side end surface of the piston sleeve 8011, and a second one-way valve 80114 is provided on the oil discharge pipe 80112. The first rotating shaft 8019 is installed in the equipment room 2022 and is rotatably connected to the hydraulic cylinder 202. The cam 8014 is installed on the first rotating shaft 8019. The piston head 8012 is installed in the piston sleeve 8011 and is slidably connected thereto. The top of the connecting rod 8013 is rotatably connected to the piston head 8012, and the bottom of the connecting rod 8013 is rotatably connected to the cam 8014.

[0055] When the cam 8014 rotates, the cam 8014 drives the piston head 8012 to slide reciprocatingly downward through the connecting rod 8013. When the piston head 8012 slides downward, negative pressure is formed in the piston sleeve 8011, thereby sucking hydraulic oil from the second hydraulic chamber 2023 through the oil suction pipe 80111. When the piston head 8012 moves upward, the piston head 8012 squeezes the hydraulic oil upward into the first hydraulic chamber 2021, thereby causing the hydraulic rod 201 to slide upward, thereby achieving the purpose of adjusting the height of the support column 2 to adapt to different installation terrains.

[0056] Furthermore, a worm 8017 is provided on the first rotating shaft 8019 , a knob 8016 is installed on the side end surface of the hydraulic cylinder 202 and is rotatably connected thereto, a worm 8017 cooperating with a worm wheel 8018 is provided on the knob 8016 , and a hexagonal hole 80161 is provided on the knob 8016 .

[0057] Insert a hexagonal wrench into the hexagonal hole 80161 and turn the knob 8016, so that the knob 8016 drives the cam 8014 to rotate under the action of the worm wheel 8018 and the worm 8017, thereby adjusting the height of the support column 2. The cooperation between the worm wheel 8018 and the worm 8017 effectively reduces the transmission resistance.

[0058] Furthermore, the top of the return pipe 8021 is connected to the bottom of the first hydraulic chamber 2021, and the bottom of the return pipe 8021 is connected to the top of the second hydraulic chamber 2023. The return pipe 8021 is provided with a valve pipe 8022 perpendicular to it, and the valve block 8023 is movably installed in the valve pipe 8022. The valve block 8023 is provided with a valve hole 80231 corresponding to the return pipe 8021, and an adjusting plate 80233 is provided at the front end of the valve block 8023.

[0059] By pulling or rotating the adjustment plate 80233, the valve hole 80231 is aligned with the return pipe 8021, so that the return pipe 8021 connects the first hydraulic chamber 2021 and the second hydraulic chamber 2023, so that the hydraulic oil in the first hydraulic chamber 2021 can flow back to the second hydraulic chamber 2023, so that the height of the support column 2 can be lowered.

[0060] Furthermore, the second spring 8024 is installed in the valve tube 8022, and the valve block 8023 is installed in the valve tube 8022 and elastically slidably connected to it through the second spring 8024. A limiting rib 80234 is provided on the valve block 8023, and a limiting groove 80221 cooperating with the limiting rib 80234 is provided on the side of the valve tube 8022.

[0061] Through the cooperation between the limiting rib 80234 and the limiting groove 80221, it is more convenient to determine the position of the valve hole 80231, thereby facilitating the closing and opening of the return pipe 8021. In combination with the second spring 8024 structure, when the limiting rib 80234 and the limiting groove 80221 are misaligned, it can effectively prevent the support column 2 from shrinking due to accidental touch.

[0062] Furthermore, scale lines 2011 are evenly arranged on the side of the hydraulic rod 201, and pin holes 103 are arranged on the side of the clamping plate 1. The clamping plate 1 and the support column 2 are rotatably connected through the pin holes 103 and the pin shaft.

[0063] The scale line 2011 facilitates reading the extension height of the hydraulic rod 201 of the support column 2, thereby facilitating accurate adjustment of the height of the support column 2.

[0066] Step 1: Assemble the pillars. First, assemble the clamping plate 1 and the support column 2 through the pin shaft. Pass the pin shaft through the pin hole 103 on the side of the clamping plate 1 so that the clamping plate 1 can rotate flexibly on the top of the support column 2, thereby completing the connection between the two and laying the foundation for the subsequent installation steps.

[0067] When the locking cam 701 is in the locked state, the locking cam 702 is in the locked state, and the locking cam 702 is in the locked state.

[0068] Step 3, fix the clamping plate 1 and the pulling plate 4, insert the fixing bolt 703 into the second mounting hole 101 of the clamping plate 1, during the insertion process, ensure that the reinforcing convex ridges 7031 on the surface of the fixing bolt 703 are aligned with the ridge grooves 7014 on the positioning ring 701, so that the fixing bolt 703 can smoothly pass through the positioning ring 701, and then tighten the nut and the fixing bolt 703 to fix the clamping plate 1 and the pulling plate 4 together through the fixing bolt 703, thereby enhancing the connection strength and stability of the entire structure, completing the final fixation of the clamping plate 1 and the pulling plate 4, thereby reliably connecting the X-shaped oblique support column and the support column 2;

[0069] Step 4: Fine-tune the height of the support column 2. Insert a hexagonal wrench into the hexagonal hole 80161 on the knob 8016 and turn the knob 8016. Since the worm 8017 on the knob 8016 cooperates with the worm wheel 8018 on the first shaft 8019, turning the knob 8016 will cause the first shaft 8019 to rotate, thereby driving the cam 8014 to rotate. When the cam 8014 rotates, the piston head 8012 is driven to rotate in the piston sleeve 8019 through the connecting rod 8013. 11, when the piston head 8012 slides downward, negative pressure is formed in the piston sleeve 8011, and under the action of the first one-way valve 80113, the hydraulic oil is sucked into the piston sleeve 8011 from the second hydraulic chamber 2023 through the oil suction pipe 80111. When the piston head 8012 moves upward, under the action of the second one-way valve 80114, the piston squeezes the sucked hydraulic oil upward and presses it into the first hydraulic chamber 2023 through the oil discharge pipe 80112. 1, thereby pushing the hydraulic rod 201 to slide upward, so that the support column 2 is raised, so as to achieve the purpose of fine-tuning and raising the height of the X-shaped oblique support to adapt to different installation terrains and height requirements of building structures. By pulling or rotating the adjustment plate 80233 at the front end of the valve block 8023, the valve hole 80231 on the valve block 8023 is aligned with the return pipe 8021. At this time, the return pipe 8021 connects the first hydraulic chamber 2021 and the second hydraulic chamber 2023. Since the pressure in the first hydraulic chamber 2021 is higher than that in the second hydraulic chamber 2023, under the action of the pressure difference, the piston plate 2024 in the second hydraulic chamber 2023 moves downward under the push of the hydraulic oil, so that the hydraulic oil in the second hydraulic chamber 2023 can flow back to the first hydraulic chamber 2021 through the return pipe 8021, so that the height of the support column 2 is reduced, and the height of the X-shaped oblique support is finely adjusted and reduced, which is also to meet the installation and adjustment requirements under different working conditions.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
