Description

Technical Field

[0001] The present invention relates to the technical field of pipeline supports, and in particular to an anti-seismic support for pipelines in a pipe gallery. Background Art

[0002] In urban construction, in order to facilitate the inspection and monitoring of pipelines, as well as to achieve unified planning, unified design, unified construction and management, it is necessary to build integrated pipeline corridors in the city, referred to as pipeline corridors. Centralized installation and management of pipelines can be achieved in pipeline corridors. During installation, in order to prevent damage to pipelines caused by vibration, seismic supports are required to be used in pipeline corridors to achieve pipeline installation.

[0003] However, the existing pipeline corridor seismic support still has the following defects during use:

[0004] 1. Existing pipeline seismic supports in pipe galleries are all installed in a flat manner. Although seismic components can be used on a single pipeline to achieve seismic effects, the overall stability is poor. At the same time, the installation operation of the pipeline is cumbersome, which reduces the installation efficiency.

[0005] 2. In order to avoid damage to pipelines caused by vibration, the existing pipeline corridor seismic supports need to buffer the vibration of the pipelines, but this will also increase the swing of the pipelines. The existing seismic supports cannot further clamp the pipelines during vibration. Therefore, although they can achieve seismic resistance, they will also loosen the fixation of the pipelines after vibration, reducing the safety of the pipelines in later use. Summary of the invention

[0016] Furthermore, the upper limit rotation connection of the top ratchet disk of the mounting column is connected with a limit rod, and the limit rod is clamped with the ratchet disk. A torsion spring is provided at the limit rotation connection between the limit rod and the mounting column, so that the limit rod can rotate elastically, so that the limit rod can limit the ratchet disk, thereby realizing stable unidirectional rotation of the ratchet disk.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A pipeline seismic support for a pipe gallery according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 7 As shown, a seismic support for pipelines in a pipe gallery comprises a wall 1, a fixing rod 2 is fixedly installed on the right end of the wall 1, a mounting column 3 is fixedly installed on the right end of the fixing rod 2, connecting plates 4 are symmetrically and evenly fixedly installed on the front and rear sides of the periphery of the mounting column 3, arc guide rails 5 are fixedly installed between the front and rear connecting plates 4 away from the sides of the mounting column 3, sliders 6 are symmetrically limited and slidably connected inside the arc guide rails 5, a spring 7 is fixedly connected between the two sliders 6, and a limiting ring 8 is limited and rotatably connected to the side of the slider 6 close to the mounting column 3, the arc guide rail 5 is fixedly installed on the outside of the mounting column 3 through the connecting plates 4 at the front and rear ends, and the arc guide rail 5 is symmetrically front and back on the outside of the mounting column 3, the arc guide rails 5 on the front and rear sides are evenly distributed on the outside of the mounting column 3, and a gap larger than the pipeline diameter is left between adjacent arc guide rails 5, so that the pipeline can be placed in the limiting ring 8 through the gap between the arc guide rails 5.

[0037] A fastening assembly 9 is arranged between the limiting ring 8 and the inside of the mounting column 3, and the fastening assembly 9 is used to control the contraction or expansion of the limiting ring 8. An anti-seismic and anti-loosening assembly 10 is arranged between the bottom side of the mounting column 3 and the wall 1, and the anti-seismic and anti-loosening assembly 10 is used to elastically support the mounting column 3 and clamp the pipeline when it vibrates.

[0038] When installing the earthquake-resistant bracket and pipeline, first use the fixing rod 2 to fix the wall 1 to achieve the fixed installation of the installation column 3, and then install the earthquake-resistant and anti-loosening component 10 between the bottom side of the installation column 3 and the wall 1 to elastically support the installation column 3.

[0039] After completing the installation of the mounting column 3, the pipeline to be fixed is placed between the limiting rings 8 through the gap between the arc guide rails 5, and then the limiting rings 8 are driven to shrink at the same time through the fastening assembly 9. During the shrinkage process, the slider 6 connected to the outer end of the limiting ring 8 will stretch the spring 7 against each other and move to both sides, thereby uniformly clamping and fixing the placed pipelines. The operation is convenient and the efficiency of pipeline installation is improved. The design of evenly distributed limiting rings 8 on the outer side of the mounting column 3 can enable the pipeline to be installed in a circular shape, and the overall structural stability is higher.

[0040] Furthermore, if Figure 2 , Figure 4-Figure 10 As shown, the fastening assembly 9 includes a rotating shaft 91, the internal limit rotation connection of the mounting column 3 is connected with the rotating shaft 91, the front and rear ends of the rotating shaft 91 are symmetrically fixedly installed with threaded disks 92, the internal limit sliding connection of the front and rear sides of the mounting column 3 is uniformly connected with tooth blocks 93, the outer sides of the front and rear threaded disks 92 are provided with symmetrical spiral threads, and the tooth blocks 93 on the front and rear sides are evenly distributed on the outer sides of the threaded disks 92 and are meshed with the threaded disks 92. Therefore, when the rotating shaft 91 drives the threaded disks 92 on both sides to rotate synchronously, it can drive the tooth blocks 93 on both sides to extend outward or retract inward at the same time.

[0041] A cylindrical tube 94 is fixedly installed at one end of the outer side of the tooth block 93. The cylindrical tube 94 extends outward to the outer side of the mounting column 3 and is slidingly connected with the mounting column 3 to facilitate the telescopic movement of the cylindrical tube 94. A connecting rod 95 is slidingly connected inside the cylindrical tube 94. The connecting rod 95 is located at one end inside the cylindrical tube 94 and is fixedly connected with a spring 96 between the inner wall of the cylindrical tube 94. A mounting block 97 is fixedly installed at one end of the outer side of the connecting rod 95. The cylindrical tube 94, the connecting rod 95 and the mounting block 97 are located between adjacent arc guide rails 5, and the inner sides of the adjacent side limit rings 8 between adjacent arc guide rails 5 are hinged to the mounting block 97 after they are brought close to the middle, so that the movement of the mounting block 97 can pull the limit rings 8 between adjacent arc guide rails 5 to tighten or expand.

[0042] The fastening assembly 9 also includes a conical wheel disk 98, which is fixedly installed on the periphery of the middle part of the rotating shaft 91, and a bevel gear 99 is connected to the right-side limiting rotation inside the mounting column 3. The bevel gear 99 and the conical wheel disk 98 are meshed with each other, so that the rotation of the bevel gear 99 can drive the conical wheel disk 98 to rotate. A bolt head 910 is fixedly installed on the right end of the bevel gear 99, and the bolt head 910 is exposed on the right side of the mounting column 3, which is convenient for driving the bolt head 910 and the bevel gear 99 to rotate by a hexagonal wrench.

[0043] The principle of the fastening assembly 9 driving the limit ring 8 to contract or expand is as follows:

[0044] When it is necessary to drive the limiting ring 8 to contract and clamp the pipeline, the bolt head 910 and the bevel gear 99 are driven to rotate by the cooperation of the hexagonal wrench and the bolt head 910. The bevel gear 99 and the bevel wheel disk 98 are engaged with each other. During the rotation of the bevel gear 99, the bevel wheel disk 98 can be driven to rotate, and then the threaded disks 92 on the front and rear sides are driven to rotate synchronously through the rotating shaft 91. During the rotation of the threaded disk 92, the tooth blocks 93 on both sides are engaged with each other on the outside of the threaded disk 92, and the tooth blocks 93 are limited and slidingly connected inside the mounting column 3, so that the tooth blocks 93 can be driven to move inward at the same time, thereby driving the cylindrical tube 94 fixed on the outside to move inward.

[0045] During the process of the cylindrical tube 94 moving inward, the spring 2 96 can be used to pull the mounting block 97 inward through the connecting rod 95. By utilizing the hinged connection between the mounting block 97 and the inner side of the limiting ring 8 of the arc guide rail 5, during the process of the mounting block 97 moving inward, the limiting ring 8 can be contracted to clamp and fix the pipeline. Through the action of the spring 2 96 on the connecting rod 95 and the action of the spring 1 7 between the sliders 6, after the pipeline is clamped and fixed, the vibration generated can also be buffered to achieve an anti-seismic effect.

[0046] By rotating the bolt head 910 in the opposite direction and utilizing the threaded disk 92 to move the tooth block 93 outward, thereby pushing the mounting block 97 outward, and in conjunction with the spring 7 pulling the slider 6 under the action of the restoring force, the limiting ring 8 can be expanded.

[0047] Furthermore, if Figure 1 , Figure 10-Figure 14 As shown, the anti-seismic loosening prevention component 10 includes a fixed plate 101 fixedly installed below the fixed rod 2 at the right end of the wall 1, a support sleeve 102 is connected to the right side of the fixed plate 101 in a limited rotation connection, a support rod 103 is connected to the inside of the support sleeve 102 in a sliding manner, the support rod 103 is connected to the left bottom of the installation column 3 at a limited rotation connection away from the support sleeve 102, a spring 3 104 is fixedly connected between one end of the support rod 103 located inside the support sleeve 102 and the inner wall of the support sleeve 102, and the support sleeve 102 and the support rod 103 are used to realize elastic support for the left bottom of the installation column 3. A ratchet disc 105 is fixedly installed on the side end of the cone wheel disc 98 outside the rotating shaft 91, and a sliding rod 106 is arranged between the wall 1 and the mounting column 3. One side of the sliding rod 106 is connected to the wall 1 for limited rotation, and the other side extends to the inside of the mounting column 3. The sliding rod 106 is located on one side inside the mounting column 3 and is tangent to the ratchet disc 105, and a ratchet tooth 107 is elastically hinged near one side of the ratchet disc 105 at the tangent point between the sliding rod 106 and the ratchet disc 105. The ratchet tooth 107 is meshed with the ratchet disc 105, so that during the movement of the sliding rod 106, the ratchet disc 105 can be pushed to rotate unidirectionally.

[0048] The upper limit rotation connection of the top ratchet disk 105 of the mounting column 3 is connected to a limit clamping rod 108, and the limit clamping rod 108 is clamped with the ratchet disk 105. A torsion spring is provided at the limit rotation connection between the limit clamping rod 108 and the mounting column 3, so that the limit clamping rod 108 can rotate elastically, so that the limit clamping rod 108 can limit the ratchet disk 105, so as to realize stable unidirectional rotation of the ratchet disk 105.

[0049] After the installation of the anti-seismic and anti-loosening component 10 is completed, the spring 104 inside the support sleeve 102 acts on the support rod 103 to achieve elastic support for the bottom of the mounting column 3 to buffer the shaking of the mounting column 3 during vibration. When the shaking amplitude caused by the vibration is large, the shaking of the mounting column 3 will cause the slide bar 106 to swing relative to the mounting column 3. During the swinging process, the ratchet teeth 107 on the slide bar 106 mesh with the ratchet disc 105 on the outer periphery of the rotating shaft 91 to push the ratchet disc 105 The one-way rotation of the rotating shaft 91 and the limit control of the ratchet disk 105 by the limit lever 108 can make the ratchet disk 105 and the rotating shaft 91 perform stable one-way rotation, and the direction of rotation is the direction in which the rotating shaft 91 drives the threaded disk 92 to move the tooth block 93 inward, thereby making the connecting rod 95 and the mounting block 97 further pull the limit ring 8 inward to increase the clamping force of the limit ring 8 on the pipeline. Therefore, when the vibration produces a large shaking, the loosening of the pipeline after the vibration is avoided, thereby improving the safety of the pipeline in the later use.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
