Description

Technical Field

[0001] The invention relates to the technical field of earthquake-resistant supports, in particular to an earthquake-resistant support for laying suspended electric power engineering cable pipes. Background Art

[0002] In the application of the power engineering industry, in order to facilitate the laying and hanging installation of cables, it is necessary to set a hanging bracket, such as a wire bridge structure, at the installation location of the cable. The hanging setting of the bracket is used to support and position the cable pipeline to prevent the cable pipeline from moving or shifting due to vibration or shock caused by external force loads during installation and use. At the same time, the earthquake resistance of the bracket can also provide suspended isolation protection for the cable pipeline while positioning the cable pipeline.

[0003] The existing anti-seismic bracket for laying cable pipes in power engineering generally uses the function of springs to provide overall anti-seismic protection for cable pipes. However, in actual use, because the cable pipes themselves have toughness and anti-deformation deflection, when they are suspended, their overall deformation amplitude is not large.

[0004] In order to lay the cable pipeline and realize the complete and effective support positioning of the cable pipeline during laying, it is necessary to restrict the front and rear positions and the up and down heights of the adjacent seismic support positioning and installation according to the routing of the cable pipeline and the maximum deformation deflection, so as to prevent the large positioning gap between adjacent groups of seismic support, resulting in up and down misalignment and front and back stratification, which will lead to unstable reinforcement of the cable pipeline and affect the stability of the laying of the cable pipeline.

[0005] The existing seismic brackets need to be precisely restricted in their fixed installation positions when in use, which affects the convenience of the bracket's own positioning and installation. At the same time, after the seismic brackets position and clamp the cable pipelines, it is easy for the local fixed positions of the cable pipelines to be suspended due to the corresponding seismic bracket installation positions being too low or too high or misaligned front and back. Long-term use causes stress damage to the local hanging positions of the cable pipelines.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original earthquake-resistant support for laying cable pipes in power engineering. Summary of the invention

[0007] The purpose of the present invention is to provide a suspended seismic support for laying cable pipes in electric power projects, so as to solve the problem that the existing seismic support for laying cable pipes in electric power projects mentioned in the above background technology is inconvenient to install, and it is easy for the seismic support to position and clamp the cable pipeline, and the local fixed position of the cable pipeline is easily damaged due to the corresponding installation position of the seismic support being too low or too high or misaligned front and back, resulting in stress damage at the local hanging position of the cable pipeline.

[0017] Preferably, the bottom outer wall and the top outer wall of the filling liquid bag are fixedly connected to the top of the sliding base and the bottom of the lifting base respectively, and connecting parts are fixed on the left and right sides of the lifting base. The interior of the connecting part is connected to the interior of the filling liquid bag through a pipeline. Hydraulic oil is provided in the filling liquid bag, the hydraulic elastic bag assembly and the connecting part. The lower end of the connecting part is slidably connected to the positioning guide rail fixed on the outer wall of the triangular bracket.

[0018] Preferably, the connecting member corresponds to the positioning guide rail one by one, and a vertical snap-fit ​​and horizontally fitting sliding connection is formed between the lower end of the connecting member and the positioning guide rail.

[0019] Preferably, the buffering and shock-absorbing component includes a buffering telescopic rod fixed inside the triangular bracket and on the left and right sides of the sliding base. The end of the output shaft of the buffering telescopic rod facing the sliding base is set to a rubber ball structure. The end of the rubber ball structure of the output shaft of the buffering telescopic rod is in contact with the bottom outer wall of the sliding base, and the interior of the buffering telescopic rod is connected with the interior of the lifting hose and the liquid capsule ball through the guide tube.

[0021] Preferably, the liquid capsule ball is suspended at the end of the triangular bracket, and the damping principle is used to weaken external force vibration and release the load. An anti-fall elastic pull rope is also provided between the outer side of the liquid capsule ball and the end of the triangular bracket to prevent the liquid capsule ball from falling.

[0022] Compared with the prior art, the invention has the following beneficial effects: the seismic support for laying suspended power engineering cable pipes is convenient for laying, installing and positioning the cable pipes, and will not cause the cable pipes to be suspended in a local position due to the upper and lower misalignment and front and rear stratification between adjacent supports. At the same time, the cable pipes in use can be damped and external force loads can be weakened, and the cable pipes in use can be isolated and protected. The specific contents are as follows:

[0023] 1. It is only necessary to install the first positioning clamp and the second positioning clamp relative to each other, and the expansion angle and the clamping assembly positioning are changed by tightening the elastic band between the two. The cable tube arranged inside the first positioning clamp and the second positioning clamp is wrapped and installed by tightening the elastic band. The elasticity and toughness of the tightening elastic band can achieve stable and rapid positioning of the cable tube. At the same time, it can also effectively improve the seismic performance of the cable tube installation. The reserved length of the tightening elastic band between the first positioning clamp and the second positioning clamp can be changed according to the use. By using the tightening adjustment component, the tightening elastic band can be used for the rapid installation of cable tubes with different diameters.

[0024] 2. The use of the tightening elastic band is changed by adjusting the artificial rotation angle of the adjusting rod. The adjusting rod and the winding wheel are driven by a worm gear structure to achieve a one-way adjustment effect of the adjusting rod on the winding wheel. The forward and reverse rotation of the winding wheel changes, and the tightening elastic band wound thereon can be wound and loosened. The tightening elastic band and the first positioning clamp and the second positioning clamp are all installed through sliding, making it more convenient to adjust the length of the tightening elastic band. At the same time, after the length is adjusted, it will not be reset under the action of its own weight and the inertia of the object;

[0025] 3. The threaded connection between the adjusting screw and the sliding base enables the adjusting screw to be rotated to adjust the positioning height of the lifting base and the first positioning clamp and the second positioning clamp thereon according to the use, so that there will be no local cable pipe hanging caused by up and down misalignment between adjacent anti-seismic brackets. At the same time, the lifting base is raised and lowered under the action of the adjusting screw. The adjusting screw can also change the compression degree of the hydraulic elastic bag assembly through the relative squeezing effect between the push plate and the hydraulic elastic bag assembly, so that the internal oil is introduced into the connecting piece set by the filling liquid bag and the hydraulic telescopic rod, so as to achieve the effect of lifting and positioning the bottom support and the side connection positioning at the same time when the lifting base is lifted and lowered, which can avoid the lifting and positioning height of the lifting base only by the connection node of the adjusting screw, and the stress damage of the connection node of the adjusting screw and the lifting base when the cable pipe is installed;

[0026] 4. The relative sliding installation of the sliding base and the triangular bracket causes the sliding base and the lifting base and the first positioning clamp and the second positioning clamp thereon to change their positioning positions, resulting in that the adjacent seismic-resistant brackets will not be damaged by local suspension stress of the cable pipe due to the front and rear stratification of the installation position. At the same time, the sliding base and the triangular bracket installed relatively slidingly use the buffer telescopic rod to perform side deformation. When encountering vibration of external force load, the buffer telescopic rod telescopes to weaken the load impact. At the same time, the oil is introduced into the liquid capsule ball and the elastic capsule bag to weaken the external force of the impact load. In addition, the suspended elastic capsule bag and liquid capsule ball, when in use, can be used for irregular suspension shaking relative to the damper application, and the external force of the vibration load is quickly weakened to achieve the seismic-resistant effect of the cable pipe laying.

[0043] A triangular bracket 1 is fixed to the wall by bolts, and a sliding base 2 is arranged on the triangular bracket 1, an adjusting screw 3 is installed through the middle of the sliding base 2, and the upper end of the adjusting screw 3 is rotatably connected to a lifting base 4 through a bearing, and a first positioning clamp 5 and a second positioning clamp 6 are installed on the top of the lifting base 4, and the cable tube is positioned by the first positioning clamp 5 and the second positioning clamp 6;

[0044] In the above technical scheme, the tripod bracket 1 is positioned and installed by bolts. In order to avoid that the cable pipe installed on the seismic support is not on the same horizontal line due to the upper and lower stratification and front and rear misalignment of the installation, and the cable pipe installed on the seismic support is suspended, and stress damage occurs in the hanging position due to long-term use, the rotation of the screw rod 3 can be adjusted to change the positioning height of the lifting base 4 and the first positioning clamp 5 and the second positioning clamp 6 thereon. When the first positioning clamp 5 and the second positioning clamp 6 are used to position the cable for laying, the upper and lower stratification phenomenon caused by installation problems between adjacent seismic support can be avoided. At the same time, the lateral sliding installation between the tripod bracket 1 and the sliding base 2 can solve the front and rear misalignment phenomenon caused by installation problems between adjacent seismic support, so that the laying of the cable pipe is more stable.

[0045] In this technical solution, if Figure 3 and Figure 4, further comprising: a second positioning clamp 6, which is hingedly rotatably mounted on the top of the lifting base 4, and the second positioning clamp 6 and the first positioning clamp 5 are positioned by a fastening elastic band 7, and the outer wall of the first positioning clamp 5 is provided with a fastening adjustment member for the fastening elastic band 7 to adjust the looseness of the fastening elastic band 7; the end of the fastening elastic band 7 passes through the second positioning clamp 6 and the top of the first positioning clamp 5 to be arranged as a snap-fitting disassembly and installation structure, and the entire middle section of the fastening elastic band 7 is arranged in the second positioning clamp 6 and the first positioning clamp 5, for the cable tube Binding positioning and earthquake resistance, and the head end of the tightening elastic band 7 is connected to the top of the first positioning clamp 5 in a penetrating sliding manner; the tightening and adjusting component includes a relaxation chamber 8 fixed to the outer wall of the first positioning clamp 5, and an adjusting rotating rod 9 is installed through the top center of the relaxation chamber 8 in a bearing-type manner, and a winding wheel 10 is installed at the transverse central axis of the relaxation chamber 8 through the central axis rotation, the head end of the tightening elastic band 7 is fixed to the outside of the winding wheel 10 in a winding manner, and the middle section of the adjusting rotating rod 9 is meshed with the middle part of the central axis of the winding wheel 10 through a worm and worm gear structure;

[0046] In the above technical scheme, the second positioning clamp 6 and the first positioning clamp 5 perform preliminary positioning of the cable tube for installation, and the cable tube body is mainly clamped and positioned by the tightening elastic band 7. The setting of the tightening elastic band 7 can wrap the cable tube for positioning, while improving the seismic effect of the cable tube suspension installation, and the relaxation length of the tightening elastic band 7 is adjusted by the tightening adjustment component where the relaxation cavity 8 is located, and the worm gear structure between the adjusting rotating rod 9 and the winding wheel 10 is engaged and driven, so that the winding wheel 10 rotates synchronously when the adjusting rotating rod 9 rotates, and the tightening elastic band 7 wrapped around the outside of the winding wheel 10 is wound or relaxed, so that the length of the tightening elastic band 7 reserved on the inner side of the second positioning clamp 6 and the first positioning clamp 5 is changed, and the cable tube is quickly positioned, and the effective positioning and stable reinforcement of cable tubes of different diameters are effectively performed.

[0047] Embodiment 2: Figure 5-Figure 9 As shown, this embodiment further discloses a lifting member in the anti-seismic bracket on the basis of the first embodiment, which is used to change the positioning height of the second positioning clip 6 and the first positioning clip 5, and its specific contents are as follows:

[0048] The lifting member is arranged on the sliding base 2, and utilizes hydraulic action to adjust the bottom and side stability of the lifting base 4 during lifting; the adjusting screw 3 and the sliding base 2 are vertically coaxially distributed, and the upper outer wall and the middle and lower outer wall of the adjusting screw 3 are respectively arranged as a threaded structure and a smooth structure, and the upper outer wall of the adjusting screw 3 and the top of the sliding base 2 are connected by a through thread, and the middle and lower outer wall of the adjusting screw 3 and the bottom of the sliding base 2 are connected by a through sliding connection; the lifting member includes a push plate 401 fixed in the middle section of the adjusting screw 3, and balls are evenly distributed in the middle of the push plate 401, and a hydraulic elastic bag component 402 is arranged on the top of the sliding base 2, and the hydraulic elastic bag component 4 The bottom center of 02 is connected to the outer wall of the middle and lower sections of the adjusting screw 3 in a penetrating sliding manner, and the top of the hydraulic elastic bag assembly 402 is connected to the filling liquid bag 403 on the outer side of the top of the sliding base 2; the bottom outer wall and the top outer wall of the filling liquid bag 403 are respectively fixedly connected to the top of the sliding base 2 and the bottom of the lifting base 4, and the left and right sides of the lifting base 4 are also fixed with connecting parts 404, the interior of the connecting part 404 is connected to the interior of the filling liquid bag 403 through a pipeline, and hydraulic oil is provided in the filling liquid bag 403, the hydraulic elastic bag assembly 402 and the connecting part 404, and the lower end of the connecting part 404 is connected to the positioning guide rail 405 fixed on the outer wall of the triangular bracket 1 in a sliding manner;

[0049] By adjusting the rotation of the adjusting screw 3, there is a through-threaded connection between the adjusting screw 3 and the top of the sliding base 2, so that the rotation of the adjusting screw 3 directly lifts the height of the lifting base 4 and the second positioning clamp 6 and the first positioning clamp 5. While lifting the height, the push plate 401 in the middle section of the adjusting screw 3 pushes the hydraulic elastic bag component 402 to compress, so that the oil stored in the hydraulic elastic bag component 402 is introduced into the filling liquid bag 403 and the connecting member 404 through the pipeline, and the connecting member 404 and the filling liquid bag 403 are both expanded and extended, and the filling liquid bag 403 is filled into the gap between the lifting base 4 and the sliding base 2. The connecting member 404 is telescopically connected and positioned with the positioning guide rail 405, so that after the lifting base 4 is lifted, its bottom and sides have good positioning and connection effects, so that the overall positioning and installation of the lifting base 4 is stable, and when in use, the connection node between its bottom and the adjusting screw 3 will not be damaged by stress shear fracture under load due to the load, so that the use of the lifting base 4 is more stable;

[0050] The connecting member 404 corresponds to the positioning rail 405 one by one, and the lower end of the connecting member 404 and the positioning rail 405 form a vertically clamped and horizontally fitted sliding connection;

[0051] The arrangement of the connecting member 404 and the positioning guide rail 405 ensures that the connecting member 404 is connected to the positioning guide rail 405 as an integrated structure during telescopic movement, and at the same time ensures that when the lifting base 4 moves in the front and rear positions of the lift, it will not move out of place, resulting in collision damage to the internal components when using the seismic bracket.

[0052] Embodiment 3: Figure 10-13 As shown, this embodiment, on the basis of the first and second embodiments, provides a buffering and shock absorbing component of the earthquake-resistant bracket, which is applied to the earthquake-resistant protection of the external force load when the bracket is used, and its specific contents are as follows:

[0053] The buffer shock-absorbing component is located at the side of the through-sliding connection between the triangular bracket 1 and the sliding base 2, and utilizes hydraulic anti-vibration and damping to release the vibration reaction force; the buffer shock-absorbing component includes a buffer telescopic rod 11 fixed inside the triangular bracket 1 and on the left and right sides of the sliding base 2, and the output shaft end of the buffer telescopic rod 11 facing the sliding base 2 is set to a rubber ball structure, and the output shaft rubber ball structure end of the buffer telescopic rod 11 is in contact with the bottom outer wall of the sliding base 2, and the interior of the buffer telescopic rod 11 is connected with the lifting hose 13 and the liquid capsule ball 14 through the guide tube 12, and the liquid capsule ball 14 is connected through the lifting hose 13 and the liquid capsule ball 14. The lifting hose 13 is suspended and fixed at the end position of the triangular bracket 1; the liquid sac ball 14 is set as an internal double-cavity structure adjacently distributed on the left and right sides, and the double cavities are isolated from each other, and the double cavities of the liquid sac ball 14 are connected with the two lifting hoses 13 in a one-to-one correspondence, and the lifting hoses 13, the guide tube 12 and the buffer telescopic rod 11 are all set in a one-to-one correspondence, and elastic bags 15 are fixed on the outside of the double cavities of the liquid sac ball 14, and hydraulic oil is set in the liquid sac ball 14, the lifting hose 13, the guide tube 12 and the buffer telescopic rod 11, and the inner wall of the lifting hose 13 is embedded with a reinforced silk armor layer structure;

[0054] In the above technical scheme, since the triangular bracket 1 and the sliding base 2 are installed to slide relative to each other, the contact friction between the two is reduced by the repulsive effect of the magnets. When subjected to vibration such as external force collision, the relative positions of the triangular bracket 1 and the sliding base 2 move. Since a buffer telescopic rod 11 is installed between the two, when the above-mentioned sliding base 2 moves on the triangular bracket 1, the buffer telescopic rod 11 is extended and retracted, so that the oil inside it is exchanged through the guide tube 12, the hanging hose 13 and the liquid capsule ball 14. In this process, the external vibration force is converted into the moving force of the sliding base 2, and the telescopic kinetic energy of the buffer telescopic rod 11 and the circulation kinetic energy of the oil and the expansion kinetic energy of the elastic bag 15 on the liquid capsule ball 14 are used to weaken the external vibration force. At the same time, the liquid capsule ball 14 is suspended by the hanging hose 13 and the weight of the oil inside it, forming a damper structure installed at the end of the triangular bracket 1. When the anti-seismic bracket is subjected to external force collision and vibration, the liquid capsule ball 14 uses the swinging effect to release the energy of the impact and collision, so as to achieve the shock-absorbing effect of the anti-seismic bracket.

[0055] The liquid capsule ball 14 is suspended at the end of the triangular bracket 1, and the damping principle is used to weaken the external force vibration and release the load. An anti-fall elastic pull rope is also arranged between the outer side of the liquid capsule ball 14 and the end of the triangular bracket 1 to prevent the liquid capsule ball 14 from falling. The setting of the anti-fall elastic pull rope improves the installation stability of the liquid capsule ball 14 and prevents damage due to falling impact.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
