Description

Technical Field

[0001] The present invention relates to the technical field of pipeline seismic supports, and specifically to a floor pipeline seismic support. Background Art

[0002] With the acceleration of the urbanization process, the scale and complexity of buildings are constantly increasing. Due to frequent crustal plate movements, earthquake disasters occur frequently in some areas, posing a huge threat to the pipeline systems in buildings.

For these reasons, floor pipeline seismic supports have emerged. Traditional supports have exposed many drawbacks during earthquakes, such as poor applicability and difficulty in dealing with complex pipeline layouts; insufficient versatility, increasing the difficulty of design and installation; A Chinese invention patent, a fixing device for a water supply pipeline in a construction project (application number: 202322490925.6), includes a support crossbeam, and main body fixing components, two-end support components, and front-end support components are arranged at both ends of the support crossbeam; a pipeline binding component is also arranged on the support crossbeam.

[0022] The following will further describe the present invention in detail with reference to the embodiments given in the drawings.

[0023] As shown in the figure, an anti-seismic support for floor pipelines in this embodiment includes a main arm 1, two side arms 2, a support arm 3, a restraint steel belt 4, and two synchronous motors 5 respectively arranged corresponding to the positions of the two side arms 2. The two side arms 2 are respectively rotatably connected to the two side walls of the support arm 3. An activity plate is arranged between the two side arms 2 and the support arm 3. One end of the main arm 1 is connected to the upper end of the support arm 3, and the other end is connected to an external wall. A telescopic mechanism 9 is connected between the main arm 1 and the support arm 3. The restraint steel belt 4 is placed on the upper end surface of the support arm 3, and its two ends respectively extend along the length direction of the side arm 2 to the position of the synchronous motor 5 and are connected to the synchronous motor 5. A through hole 7 for accommodating an external pipeline is formed between the restraint steel belt 4 and the upper end surface of the support arm 3. One limit slide plate 8 for adjusting the size of the through hole 7 is movably arranged on each side of the through hole 7 on the upper end surface of the support arm 3. The limit slide plate 8 can be positioned after sliding on the support arm 3; a slide rail 31 is respectively opened at both ends of the upper end surface of the support arm 3 corresponding to the limit slide plate 8. A sliding edge 81 is arranged on the limit slide plate 8, and a part of the sliding edge 81 is inserted into the slide rail 31 and is in sliding fit with it; a plurality of positioning holes 32 are evenly arranged along the length direction of the support arm 3 at the position corresponding to the slide rail 31 on the side of the support arm 3. A bolt 33 for pressing the sliding edge 81 towards the inner wall of the slide rail 31 is arranged in the positioning hole 32. The bolt 33 is detachably connected to the positioning hole 32; a first guide wheel 82 is arranged on the side of the limit slide plate 8 facing the through hole 7, and a guide wall 83 is arranged on the other side opposite to it. The guide wall 83 is inclined from the direction of the restraint steel belt 4 towards the direction of the side arm 2.

[0024] When this solution is implemented, those skilled in the art will rotatably connect the side arm 2 to both sides of the support arm 3, and an activity plate is arranged in the middle. This activity plate can swing and expand when the side arm 2 and the support arm 3 cooperate. That is, when a pipeline is placed on the support arm 3, the weight of the pipeline will press the support arm 3 downward. At this time, because the side arm 2 is connected to the support arm 3, the connection length between the side arm 2 and the support arm 3 will be extended through expansion, so that the support arm 3 can be pressed down. The movement range of the activity plate in this solution is limited. Those skilled in the art can adjust the downward movement limit distance of the support arm 3 according to the expansion length of the activity plate. When the support arm 3 is pressed down to the limit distance of the expansion of the activity plate, it will no longer move downward; one end of the main arm 1 is connected to the upper end of the support arm 3, and the other end is connected to the external wall. There is a telescopic mechanism 9 between the two. When the support arm 3 moves up and down, the telescopic mechanism 9 can assist the support arm 3 to move up and down through expansion and contraction, and make the support arm 3 always connected to the main arm 1, so that the support arm 3 is connected to the external wall. When the pipeline is installed on the support arm 3, the connection between the main arm 1 and the side arm 2 will be more stable, reducing the impact of vibration during an earthquake on the pipeline, and having good seismic resistance; the restraining steel belt 4 is placed on the upper end face of the support arm 3, and both ends are connected to the synchronous motor 5, forming a through hole 7 for accommodating the pipeline with the support arm 3. In this solution, the synchronous motor 5 is used to drive so that the restraining steel belt 4 can be restrained or released synchronously and evenly, so that the size of the through hole 7 can be enlarged or reduced evenly, and it can be applicable to pipelines of different sizes or shapes. When the synchronous motor 5 drives the restraining steel belt 4 to be tightened with the pipeline, the pipeline can be positioned on the support arm 3, with good stability, convenient operation, and the motor drive does not consume manpower. In this solution, a slidable positioning limit slide plate 8 is arranged on each side of the through hole 7. Those skilled in the art can adjust the radial width of the through hole 7 by sliding the limit slide plate 8; when this solution is implemented, on the upper end face of the support arm 3 at the positions corresponding to both ends of the limit slide plate 8, a high-precision slide rail 31 is respectively processed. The limit slide plate 8 is provided with a sliding edge 81 adapted to it, and a part of the sliding edge 81 is cleverly embedded in the slide rail 31, and the two form a smooth sliding fit structure. When it is necessary to adapt to pipelines of different diameters during actual operation, the staff only needs to apply an appropriate external force to easily push the limit slide plate 8 to slide smoothly along the slide rail 31. For example, when installing a small-diameter pipeline, the limit slide plate 8 is pushed inward to reduce the size of the through hole 7; when facing a large-diameter pipeline, the limit slide plate 8 is slid outward to increase the space of the through hole 7, so as to flexibly and accurately change the width of the through hole 7, significantly improving the adaptability of the bracket to pipelines of various diameters and fully demonstrating its universality advantage; on the side of the support arm 3, a number of positioning holes 32 are evenly distributed along the length direction of the support arm 3 corresponding to the position of the slide rail 31. When the limit slide plate 8 slides to a position adapted to the pipeline diameter, the bolt 33 is placed into the positioning hole 32. By tightening the bolt 33, the pressure generated by the bolt 33 will force the sliding edge 81 to tightly fit the inner wall of the slide rail 31, thereby realizing the firm locking of the limit slide plate 8.Since the bolt 33 and the positioning hole 32 adopt a convenient detachable connection method, if the position of the limit sliding plate 8 needs to be adjusted again later, only need to easily loosen the bolt 33, and the limit sliding plate 8 can slide freely again; this positioning method with simple operation and extremely high stability effectively avoids the accidental displacement of the limit sliding plate 8 due to factors such as vibration and displacement during the operation of the pipeline, providing a solid guarantee for the stable placement of the pipeline; the two synchronous motors 5 are respectively tightly connected to both ends of the converging steel belt 4. The synchronous motors 5 have advanced control technology in the field of motors, can control the winding and unwinding actions of the converging steel belt 4, and the two motors always run in high synchronization. When adjusting the position of the pipeline or dealing with complex and changeable working conditions, by driving the converging steel belt 4 with the synchronous motors 5, it can ensure that a uniform and stable force is applied to the pipeline, effectively avoiding damage to the pipeline caused by uneven force. When adjusting the size of the through hole 7, the precise control characteristics of the synchronous motors 5 can cooperate with the adjustment of the limit sliding plate 8. For example, when sudden situations such as earthquakes occur, the synchronous motors 5 can quickly respond according to the preset program, timely and accurately adjust the tension of the converging steel belt 4, and cooperate with the limit sliding plate 8 to provide all-round and high-strength protection for the pipeline, greatly improving the stability and reliability of the entire seismic support for fixing the pipeline.

[0025] As a specific implementation of the improvement, it includes a main arm 1, two side arms 2, a support arm 3, a converging steel belt 4 and two synchronous motors 5 respectively arranged corresponding to the positions of the two side arms 2. The two side arms 2 are respectively rotatably connected to the two side walls of the support arm 3. An activity plate is arranged between the two side arms 2 and the support arm 3. One end of the main arm 1 is connected to the upper end of the support arm 3, and the other end is connected to the external wall. A telescopic mechanism 9 is connected between the main arm 1 and the support arm 3. The converging steel belt 4 is placed on the upper end surface of the support arm 3, and its two ends respectively extend along the length direction of the side arm 2 to the position of the synchronous motor 5 and are connected to the synchronous motor 5. A through hole 7 for accommodating the external pipeline is formed between the converging steel belt 4 and the upper end surface of the support arm 3. A limit sliding plate 8 for adjusting the size of the through hole 7 is movably arranged on both sides of the through hole 7 on the upper end surface of the support arm 3. The limit sliding plate 8 can be positioned after sliding on the support arm 3; a first guide wheel 82 is arranged on one side of the limit sliding plate 8 facing the through hole 7, and a guide wall 83 is arranged on the other side opposite to it. The guide wall 83 is inclined from the direction of the converging steel belt 4 towards the side wall direction.

[0026] When this solution is implemented, those skilled in the art set two synchronous motors 5. The two synchronous motors 5 are respectively arranged corresponding to the two side arms 2 and are respectively connected to both ends of the converging steel belt 4 to control the contraction of the converging steel belt 4, so that the size of the through hole 7 can be adjusted. This solution adopts a first guide wheel 82 on the side of the limit slide plate 8 facing the through hole 7. Since the limit slide plate 8 needs to be positioned after sliding to the specified position, at this time, a fixation is formed between the limit slide plate 8 and the support arm 3. At this time, the converging steel belt 4 can contact the first guide wheel 82 on the limit slide plate 8. Since both side arms 2 in this solution are connected to the external wall at the top, when setting the converging steel belt 4, the converging steel belt 4 first contacts the first guide wheel 82 in sequence from the through hole 7 to the side arm 2 direction, then contacts the guide wall 83, and then passes through the side arm 2 and is connected to the synchronous motor 5. In this solution, the preferred inclination direction of the guide wall 83 is inclined in the direction of the converging steel belt 4 towards the side arm 2 direction. In other solutions, those skilled in the art can also set inclined walls at other angles to meet the actual requirements. In addition, this solution preferably sets a first guide wheel 82 on the side of the limit slide plate 8 facing the through hole 7. This structure saves manufacturing costs more and does not affect the guiding function. In other solutions, those skilled in the art can also set first guide wheels 82 on both sides of the limit slide plate 8 for guiding the converging steel belt 4. This structure can save manufacturing costs and has a good guiding effect, and can improve the connection stability between the pipeline and the support arm 3.

[0027] As a specific improvement embodiment, at least one limiting convex edge 821 is circumferentially arranged on the outer peripheral wall of the first guide wheel 82, and a clamping groove 41 for cooperating with the limiting convex edge 821 is arranged at the position corresponding to the limiting convex edge 821 on the upper end face of the converging steel belt 4.

[0028] When this solution is implemented, at least one limiting convex edge 821 is arranged on the outer peripheral wall of the first guide wheel 82. The structure of this limiting convex edge 821 can be used in cooperation with the converging steel belt 4 provided with the clamping groove 41 in this solution so that the converging steel belt 4 is not easily disengaged from the first guide wheel 82 during movement, improving the connection stability. When those skilled in the art install the converging steel belt 4, they need to place the clamping groove 41 on the converging steel belt 4 corresponding to the limiting convex edge 821. This solution preferably sets one limiting convex edge 821, which can save manufacturing costs and has a good limiting effect.

[0029] As a specific improvement embodiment, a second guide wheel 21 is arranged at one end of each of the two side arms 2 facing the support arm 3, and the outer peripheral wall of the second guide wheel 21 contacts the converging steel belt 4.

[0030] When this solution is implemented, a second guide wheel 21 is provided on the side arm 2, and one is provided on each of the two side arms 2. The second guide wheel 21 can directly contact the bundling steel belt 4. When the bundling steel belt 4 passes through the second guide wheel 21, the second guide wheel 21 can guide it in the direction of the side arm 2, so that the bundling steel belt 4 can cooperate with the synchronous motor 5 to be retracted more smoothly, and the guiding effect is good.

[0031] As a specific improvement embodiment, a limit stop edge 22 is provided on the side wall of each of the two side arms 2 in contact with the bundling steel belt 4. A limit cavity 23 is formed between the limit stop edge 22 and the side arm 2. The bundling steel belt 4 passes through the limit cavity 23 and is connected to the synchronous motor 5 on the same side as it.

[0032] When this solution is implemented, a limit stop edge 22 is provided on the side arm 2, and a limit cavity 23 is formed between the limit stop edge 22 and the side arm 2. In this solution, the limit stop edge 22 is preferably integrally formed with the side arm 2, which is convenient for manufacturing. The bundling steel belt 4 can be threaded through the limit cavity 23, and the limit stop edge 22 can limit the bundling steel belt 4.

[0033] As a specific improvement embodiment, the movable plate is a telescopic plate 6.

[0034] When this solution is implemented, this solution preferably uses the telescopic plate 6 as the movable plate, and the effective distance between the side arm 2 and the support arm 3 is extended by the telescoping of the movable plate.

[0035] As a specific improvement embodiment, the telescopic mechanism 9 includes a telescopic tube 91. A fixing plate 92 is provided at one end of the telescopic tube 91 facing the support arm 3. The fixing plate 92 is integrally formed with the telescopic tube 91. One end of the telescopic tube 91 is fixedly connected to the main arm 1, and the fixing plate 92 at the other end is laid flat on the upper end surface of the support plate and is bolted 33 to the support plate.

[0036] When this solution is implemented, this solution uses the telescopic tube 91. Since the support arm 3 in this solution will displace downward under the pressure of the pipeline weight, at this time, the telescopic tube 91 can stretch and extend the effective distance between the main arm 1 and the support arm 3, and can also prevent the support arm 3 from detaching from the main arm 1 after being pressed. Using the fixing plate 92 integrally formed with the telescopic tube 91 can make the connection strength between the fixing plate 92 and the telescopic tube 91 higher, and the contact area between the fixing plate 92 and the main arm 1 is large, and the connection is more stable, which can provide a stable supporting force for the pipeline on the support arm 3. The support plate is bolted 33 to the fixing plate 92 to improve the connection strength and is convenient for disassembly and assembly.

[0037] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
