Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to an assembled steel structure support. Background Technology

[0002] Prefabricated steel structure supports are modular support systems that adopt standardized design, factory prefabrication of components, and rapid on-site assembly. They are mainly made of high-strength steel (such as Q355) and connected into a whole by bolts or welding. Their core features are lightweight, high construction efficiency (the construction period is shortened by 30% to 50% compared with traditional structures), and environmental protection and reusability. They are widely used in construction, energy, chemical and other fields.

[0003] Existing prefabricated steel structure supports, which are connected by bolts or welding, are not convenient for flexible adjustment according to the specifications of the supported pipelines, resulting in limitations in their use. Furthermore, when supporting pipelines, existing prefabricated steel structure supports lack the ability to accommodate vibrations generated by the pipelines, such as fluid pulsation or equipment operation vibrations, which may cause the pipelines to break due to resonance. Therefore, new technical solutions need to be designed to address these issues. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to again Figure 1-5This utility model provides a prefabricated steel structure support, including a mounting frame 100. Mounting sleeves 110 are fixedly connected to both sides of the mounting frame 100. A connecting bracket 120 is slidably connected to the inner side of the mounting sleeves 110. A transmission chamber 130 is fixedly connected to the bottom of the connecting bracket 120. Gear rotating screws 140 are rotatably connected to both sides of the inner cavity of the transmission chamber 130. One end of the gear rotating screw 140 passes through the transmission chamber 130 and extends into the interior of the transmission chamber 130. A threaded sleeve 141 is screwed to the outer side of the gear rotating screw 140. A pin 142 is fixedly connected to one end of the threaded sleeve 141. One end of the pin 142 passes through the transmission chamber 130 and extends into the interior of the connecting bracket 120. A rotatable screw is connected to one side of the transmission chamber 130. A gear drive rod 150 has one end that passes through the transmission chamber 130 and extends into the inner cavity of the transmission chamber 130. The gear drive rod 150 is meshed with two gear rotating screws 140. An installation chamber 160 is fixedly connected to the bottom of the transmission chamber 130. Two tenons 161 are slidably connected inside the installation chamber 160. The top of the tenons 161 passes through the installation chamber 160 and the stake 142 and extends into the interior of the transmission chamber 130. A connecting rod 170 is fixedly connected to the bottom of the tenons 161. A compression spring 171 is sleeved on the outside of the connecting rod 170. The bottom of the connecting rod 170 passes through the installation chamber 160 and extends to the bottom of the installation chamber 160. A pull plate 180 is fixedly connected to the bottom of the connecting rod 170.

[0023] Specifically, by pulling the pull plate 180, the pull plate 180 moves the connecting rod 170, causing the connecting rod 170 to push the tenon 161 against the compression spring 171, thus releasing the limiting fixation of the insert 142 and moving it into the installation chamber 160. Then, rotating the gear drive rod 150 causes the gear drive rod 150 to drive the gear rotating screw 140 to rotate, causing the threaded sleeve 141 on the gear rotating screw 140 to move the insert 142, thus removing the insert 142 from the connecting bracket 120 and releasing the limiting fixation of the mounting frame 100. Subsequently, by sliding the mounting sleeves 110 on both sides of the mounting frame 100 on the connecting bracket 120, the mounting frame 100 is... After the height is adjusted, the gear drive rod 150 is rotated to drive the gear rotating screw 140 on both sides that are meshed with it to rotate. The screw sleeve 141 installed on the gear rotating screw 140 moves with the rotation of the gear rotating screw 140, so that the insert 142 installed on the screw sleeve 141 is inserted into the connecting bracket 120 to fix the position of the mounting bracket 100. When the insert 142 is inserted into the connecting bracket 120, the positioning hole on the insert 142 coincides with the position of the tenon 161, so that the compression spring 171 is inserted into the insert 142 to fix the position of the insert 142, thus completing the adjustment of the support height of the bracket.

[0024] Example 2: Please refer to again Figure 1-5 A base plate 200 is fixedly connected to the bottom of the inner cavity of the mounting bracket 100, and the base plates 200 are arranged in sequence. Friction plates 210 are fixedly connected to the four sides of the top of the base plate 200. A top plate 220 is slidably connected to the outer side of the friction plates 210. Friction sleeves 230 are fixedly connected to the four sides of the top of the top plate 220. The inner side of the friction sleeves 230 is in contact with the friction plates 210. Repulsive magnets 240 are fixedly connected to the top of the base plate 200 and the bottom of the top plate 220. Buffer springs 250 are fixedly connected to the four sides between the top of the base plate 200 and the bottom of the top plate 220. A bearing rod 260 is fixedly connected to the top of the top plate 220. A bearing pad 270 is fixedly connected to the top of the bearing rod 260.

[0025] Specifically, when the pipeline vibrates, the bearing pad 270 in contact with the pipeline receives the vibration, and then the bearing rod 260 connected to the bearing pad 270 receives the vibration, and the bearing rod 260 applies pressure to the top plate 220, causing the top plate 220 to slide on the friction plate 210. The friction sleeve 230 on the top plate 220 moves with the top plate 220 and rubs against the friction sleeve 230 to generate damping. At the same time, due to the movement of the top plate 220, the S poles of the repulsive magnets 240 on both sides approach each other, generating a repulsive force. Furthermore, due to the movement of the top plate 220, the buffer spring 250 installed between the top plate 220 and the bottom plate 200 deforms. Together with the friction plate 210 and the friction sleeve 230 that generate the damping force and the magnets that generate the repulsive force, the vibration is canceled and buffered.

[0026] Working principle: Pulling the pull plate 180 causes the connecting rod 170 to move, which in turn causes the tenon 161 to compress the compression spring 171, thus releasing the limiting fixation of the insert 142 and moving it into the mounting chamber 160. Then, rotating the gear drive rod 150 causes the gear drive rod 150 to rotate the screw 140, which in turn causes the threaded sleeve 141 on the screw 140 to move the insert 142, causing it to move out of the connecting bracket 120 and releasing the limiting fixation of the mounting frame 100. Finally, by sliding the mounting sleeves 110 on both sides of the mounting frame 100 on the connecting bracket 120, the mounting frame 100... The height is adjusted, and after adjustment, the gear drive rod 150 is rotated to drive the gear rotating screw 140 on both sides that are meshed with it to rotate. The screw sleeve 141 installed on the gear rotating screw 140 moves with the rotation of the gear rotating screw 140, so that the insert 142 installed on the screw sleeve 141 is inserted into the connecting bracket 120 to fix the position of the mounting bracket 100. When the insert 142 is inserted into the connecting bracket 120, the positioning hole on the insert 142 coincides with the position of the tenon 161, so that the compression spring 171 is inserted into the insert 142 to fix the position of the insert 142, thus completing the adjustment of the support height of the bracket.

[0027] When the pipeline vibrates, the bearing pad 270 in contact with the pipeline receives the vibration, and then the bearing rod 260 connected to the bearing pad 270 receives the vibration and applies pressure to the top plate 220, causing the top plate 220 to slide on the friction plate 210. The friction sleeve 230 on the top plate 220 moves with the top plate 220 and rubs against it to generate damping. At the same time, due to the movement of the top plate 220, the S poles of the repulsive magnets 240 on both sides come closer and generate repulsive force. Furthermore, due to the movement of the top plate 220, the buffer spring 250 installed between the top plate 220 and the bottom plate 200 deforms. The friction plate 210 and the friction sleeve 230, which generate damping force, and the magnets that generate repulsive force cancel out and buffer the vibration.
