Description

Technical Field

[0001] This utility model belongs to the field of steel structure support technology, specifically relating to an integrated steel structure support for fire pump rooms. Background Technology

[0002] Fire pump rooms are an extremely important component of fire protection systems, often referred to as the heart of the system, primarily responsible for supplying fire-fighting water. They are critical locations for providing fire-fighting water and are directly related to the safety of life and property.

[0003] Fire pump rooms typically house equipment such as fire hydrant pumps, sprinkler pumps, and water cannon pumps. These devices are the core of the park's fire extinguishing system. To ensure rapid and stable construction of the fire pump room, steel structures are usually used for installation. However, steel structures are mostly fixed at both ends during installation. For longer steel structures, the middle section lacks effective support. Due to the weight of the steel structure, it is prone to sagging, posing a certain safety hazard. Therefore, bracing is used to support longer steel structures. However, existing bracing structures are relatively simple in structure and cannot be adapted to the distance between the steel structure and the wall or the installation angle of the steel structure, which limits their use. Therefore, we propose an integrated steel structure bracing for fire pump rooms. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated steel structure support for fire pump rooms, in order to solve the problem mentioned in the background art that the existing support has a relatively simple structure and cannot be adapted to the distance between the steel structure and the wall or the installation angle of the steel structure, which makes the support limited in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated steel structure support for a fire pump room, comprising a support plate with several mounting holes, a support outer shell fixedly mounted on the lower surface of the support plate, an opening on the lower surface of the support outer shell with a support inner plate slidably mounted therein, a rotating shaft fixedly mounted at the bottom end of the support inner plate, a connecting seat rotatably mounted on the outer surface of the rotating shaft, a locking toothed plate fixedly mounted at one end of the rotating shaft, an mounting shell fixedly mounted on the side of the connecting seat, a locking toothed plate slidably mounted inside the mounting shell, the locking toothed plate slidably engaging with the locking toothed plate, an adjusting shell fixedly mounted on the lower surface of the connecting seat, and the adjusting shell rotatably mounted on the inner wall of the adjusting shell. The device is equipped with a bidirectional screw, one end of which extends into an adjusting shell and is fixedly fitted with a knob. Both ends of the bidirectional screw have threaded plates threaded onto their outer surfaces. A hinge seat 1 is fixedly fitted at both ends of the threaded plate. A hinge arm is hinged onto the hinge seat 1. A hinge seat 2 is hinged onto the end of the hinge arm away from the hinge seat 1. A single mounting plate 1 is fixedly fitted between the two hinge seats 2 on the same side. Two mounting plates 2 are fixedly fitted onto the lower surface of the mounting plate 1. A rotating shaft 2 is rotatably fitted onto the opposing surfaces of the two mounting plates 2. A mounting frame is fixedly fitted between the two rotating shafts 2. An arc-shaped clamping plate and a flat clamping plate are fixedly fitted onto the opposing surfaces of the mounting frame, respectively. Several mounting bolts pass through the arc-shaped clamping plate and the flat clamping plate.

[0006] By adopting the above scheme, the inner support plate and the outer support shell are used together. The inner support plate can slide relative to the outer support shell, which can be adaptively adjusted according to the distance between the steel structure and the wall. The rotating shaft, connecting seat, locking tooth plate 1, and locking tooth plate 2 can be used to adaptively adjust the angle according to the angle between the steel structure and the wall, which can be better adapted to the on-site installation of the steel structure, improving the versatility of use and making operation and adjustment convenient. By setting a two-way screw in conjunction with a threaded plate and a hinged arm, the relative movement of the two mounting plates 1 and 2 can be realized. The rotating shaft 2 and the mounting frame in conjunction with curved and flat locking plates can be used to select the appropriate locking plate to fix and install according to the surface shape of the steel structure, further expanding the scope of application.

[0007] In a preferred embodiment, the bottom end of the supporting shell is provided with a through hole 1, and a screw is inserted through the through hole 1. The inner plate of the support is provided with a plurality of through holes 2, and the screw passes through the through holes 2 and is threaded with a nut.

[0008] Using the above scheme, the screw and nut are used together. When the nut is unscrewed and the screw is pulled out, the inner support plate is unlocked and can slide relative to the outer support shell, thereby adjusting the distance between the support plate and the adjustment shell. After adjustment, the screw is passed through the first and second through holes and the nut is screwed on to lock the position. The locking structure is simple and the adjustment operation is convenient.

[0009] In a preferred embodiment, a plurality of limiting sliders are fixedly installed at one end of the inner support plate inside the outer support shell, and a plurality of limiting grooves are provided on the inner wall of the outer support shell, with the limiting sliders slidably installed on the inner wall of the limiting grooves.

[0010] Using the above scheme, when the inner support plate slides, it can drive the limiting slider one to slide within the limiting groove one. Therefore, by using the combination of the limiting slider one and the limiting groove one, the sliding stability of the inner support plate can be ensured, and the inner support plate can be prevented from detaching from the outer support shell when it slides, thus achieving a limiting effect.

[0011] In a preferred embodiment, the mounting shell has two threaded holes on its side, one of which is threaded with an adjusting bolt. The second locking toothed plate has a threaded groove on its side, and the adjusting bolt is used in conjunction with the threaded groove. Several springs are fixedly installed between the second locking toothed plate and the inner wall of the mounting shell.

[0012] Using the above scheme, an adjusting bolt is used in conjunction with a spring. When the adjusting bolt is screwed out of the threaded groove and threaded hole, the second locking toothed plate unlocks and can slide. When the second locking toothed plate disengages from the first locking toothed plate, it will compress the spring and deform. At this time, the adjusting bolt can be passed through the threaded hole at the lower position and screwed into the threaded groove to lock the position of the second locking toothed plate. At this time, the rotation angle between the inner support plate and the connecting seat can be adjusted by the rotating shaft. After adjustment, the adjusting bolt is screwed out. At this time, the spring force will drive the second locking toothed plate to reset and engage with the first locking toothed plate. The adjusting bolt is then passed through the threaded hole at the upper position and screwed into the threaded groove to lock the position of the second locking toothed plate. This can prevent the second locking toothed plate from accidentally sliding and separating from the first locking toothed plate, thus improving the stability of the use.

[0013] In a preferred embodiment, a plurality of limiting sliders are fixedly installed on the side of the locking tooth plate II, and a plurality of limiting grooves are provided on the inner wall of the mounting shell, and the limiting sliders II are slidably installed on the inner wall of the limiting grooves II.

[0014] Using the above scheme, when the second locking toothed plate slides, it will drive the second limiting slider to slide within the second limiting groove. Therefore, by using the cooperation of the second limiting slider and the second limiting groove, the stable sliding of the second locking toothed plate can be guaranteed.

[0015] In a preferred embodiment, a plurality of connecting blocks are fixedly installed on the upper surface of the mounting plate, and a plurality of guide blocks are fixedly installed on the upper surface of the adjusting shell. A guide rod is slidably installed on the guide block, one end of the guide rod is fixedly connected to the connecting block at the corresponding position, and a limit plate is fixedly installed on the other end of the guide rod.

[0016] By adopting the above scheme, the connection between the guide rod and the mounting plate is achieved by using a connecting block. The sliding of the guide rod within the guide block ensures good horizontal stability of the mounting plate and avoids wobbling. The presence of the limiting plate prevents the guide rod from detaching from the guide block when sliding, thus providing a good position limiting effect.

[0017] In a preferred embodiment, a plurality of limiting rods are fixedly installed on the inner wall of the adjusting shell, and the threaded plate is slidably installed on the outer surface of the plurality of limiting rods.

[0018] With the above scheme, when the threaded plate is driven to move during the rotation of the bidirectional screw, the threaded plate will slide on the surface of the limit rod. Therefore, the setting of the limit rod can ensure that the movement of the threaded plate is more stable and there will be no tilting or shaking.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This integrated fire pump room steel structure support uses a support shell and a support inner plate in conjunction. The support inner plate can slide relative to the support shell, allowing for adaptive adjustment based on the distance between the steel structure and the wall. Through the included pivot one, connecting seat, locking tooth plate one, and locking tooth plate two, the angle can be adaptively adjusted according to the angle between the steel structure and the wall. This allows for better adaptation to the on-site installation conditions of the steel structure, improving its versatility and making operation and adjustment convenient.

[0021] This integrated fire pump room steel structure support device uses a two-way screw rod in conjunction with a threaded plate and a hinged arm to achieve relative movement between the two mounting plates. It also uses a rotating shaft and a mounting frame in conjunction with curved and flat clamping plates, allowing for the selection of appropriate clamping plates to fix and secure the device according to the surface shape of the steel structure, thus further expanding its applicability.

[0031] Please see Figure 1-8This utility model provides an integrated steel structure support for a fire pump room, including a support plate 1 with several mounting holes. A support outer shell 2 is fixedly installed on the lower surface of the support plate 1. The lower surface of the support outer shell 2 has an opening, and a support inner plate 3 is slidably installed inside the opening. A rotating shaft 4 is fixedly installed at the bottom end of the support inner plate 3. A connecting seat 6 is rotatably installed on the outer surface of the rotating shaft 4. A locking toothed plate 5 is fixedly installed at one end of the rotating shaft 4. An installation shell 7 is fixedly installed on the side of the connecting seat 6. A locking toothed plate 8 is slidably installed inside the installation shell 7. The locking toothed plate 8 and the locking toothed plate 5 mesh with each other. An adjusting shell 9 is fixedly installed on the lower surface of the connecting seat 6. A bidirectional screw 10 is rotatably installed on the inner wall of the adjusting shell 9. One end of the bidirectional screw 10 extends out to adjust... The housing 9 is fixedly equipped with a knob. The two threads of the double-ended screw 10 are threaded with threaded plates 11. Both ends of the threaded plates 11 are fixedly equipped with hinge seats 12. Hinges 13 are hingedly mounted on hinge seats 12. Hinges 14 are hingedly mounted on the end of the hinge arm 13 away from hinge seats 12. The same mounting plate 15 is fixedly mounted between the two hinge seats 14 on the same side. Two mounting plates 16 are fixedly mounted on the lower surface of mounting plate 15. Rotating shafts 17 are rotatably mounted on the opposite surfaces of the two mounting plates 16. A mounting frame 18 is fixedly mounted between the two rotating shafts 17. Arc-shaped clamping plates 19 and flat clamping plates 20 are fixedly mounted on the opposite surfaces of the mounting frame 18. Several mounting bolts 21 pass through the arc-shaped clamping plates 19 and flat clamping plates 20.

[0032] By using the supporting outer shell 2 and the supporting inner plate 3 together, the supporting inner plate 3 can slide relative to the supporting outer shell 2, thus allowing for adaptive adjustment based on the distance between the steel structure and the wall. The rotating shaft 4, connecting seat 6, locking toothed plate 5, and locking toothed plate 8 allow for adaptive angle adjustment based on the angle between the steel structure and the wall, enabling better adaptation to the on-site installation conditions of the steel structure, improving its versatility and ease of operation. The bidirectional screw 10, in conjunction with the threaded plate 11 and hinged arm 13, enables relative movement of the two mounting plates 15 and 16. The rotating shaft 17 and mounting frame 18, in conjunction with the curved clamping plate 19 and flat clamping plate 20, allow for selection of appropriate clamping plates to secure the steel structure, further expanding its applicability.

[0033] The bottom of the supporting outer shell 2 has a through hole 1, and a screw 22 passes through the through hole 1. The supporting inner plate 3 has several through holes 2. The screw 22 passes through the through holes 2 and is threaded with a nut 23. The screw 22 and the nut 23 are used together. When the nut 23 is unscrewed and the screw 22 is pulled out, the supporting inner plate 3 is unlocked and can slide relative to the supporting outer shell 2, thereby adjusting the distance between the supporting plate 1 and the adjusting shell 9. After adjustment, the screw 22 is passed through the through holes 1 and 2 and the nut 23 is screwed on to lock the position. The locking structure is simple and the adjustment operation is convenient.

[0034] Several limiting sliders 24 are fixedly installed at one end of the inner support plate 3 inside the outer support shell 2. Several limiting grooves are opened on the inner wall of the outer support shell 2. The limiting sliders 24 are slidably installed on the inner wall of the limiting grooves. When the inner support plate 3 slides, it can drive the limiting sliders 24 to slide in the limiting grooves. Therefore, by using the combination of the limiting sliders 24 and the limiting grooves, the sliding stability of the inner support plate 3 can be ensured, and the inner support plate 3 can be prevented from detaching from the outer support shell 2 when sliding, thus achieving a limiting effect.

[0035] The mounting housing 7 has two threaded holes on its side. One of the threaded holes is threaded with an adjusting bolt 25. The side of the locking toothed plate 28 has a threaded groove. The adjusting bolt 25 works in conjunction with the threaded groove. Several springs 27 are fixedly installed between the locking toothed plate 28 and the inner wall of the mounting housing 7. The adjusting bolt 25 works in conjunction with the springs 27. When the adjusting bolt 25 is unscrewed from the threaded groove and threaded hole, the locking toothed plate 28 is unlocked and can slide. When the locking toothed plate 28 is disengaged from the locking toothed plate 15, it will compress the springs 27 and deform them. At this time, the adjusting bolt 25 can be passed through the lower position. The threaded hole is screwed into the threaded groove to lock the position of the locking toothed plate 28. At this time, the rotation angle between the inner support plate 3 and the connecting seat 6 can be adjusted by rotating shaft 14. After adjustment, the adjusting bolt 25 is unscrewed. At this time, the elastic force of spring 27 will drive the locking toothed plate 28 to reset and engage with the locking toothed plate 15. The adjusting bolt 25 is then passed through the threaded hole at the upper position and screwed into the threaded groove to lock the position of the locking toothed plate 28. This can prevent the locking toothed plate 28 from accidentally sliding and separating from the locking toothed plate 15, thus improving the stability of the use.

[0036] Several limiting sliders 26 are fixedly installed on the side of the positioning toothed plate 28. Several limiting grooves 2 are opened on the inner wall of the mounting shell 7. The limiting sliders 26 are slidably installed on the inner wall of the limiting grooves 2. When the positioning toothed plate 28 slides, it will drive the limiting sliders 26 to slide in the limiting grooves 2. Therefore, by using the combination of the limiting sliders 26 and the limiting grooves 2, the stable sliding of the positioning toothed plate 28 can be guaranteed.

[0037] Several connecting blocks 29 are fixedly installed on the upper surface of the mounting plate 15, and several guide blocks 28 are fixedly installed on the upper surface of the adjusting shell 9. A guide rod 30 is slidably installed on the guide block 28. One end of the guide rod 30 is fixedly connected to the connecting block 29 at the corresponding position, and a limit plate 31 is fixedly installed on the other end of the guide rod 30. The connecting blocks 29 are used to connect the guide rod 30 to the mounting plate 15. By allowing the guide rod 30 to slide within the guide block 28, the horizontal movement stability of the mounting plate 15 can be ensured, and shaking can be avoided. The presence of the limit plate 31 can prevent the guide rod 30 from detaching from the guide block 28 when sliding, thus providing a good position restriction effect.

[0038] Several limiting rods 32 are fixedly installed on the inner wall of the adjusting shell 9. The threaded plate 11 is slidably installed on the outer surface of the several limiting rods 32. When the bidirectional screw 10 rotates and drives the threaded plate 11 to move, the threaded plate 11 will slide on the surface of the limiting rods 32. Therefore, the setting of the limiting rods 32 can ensure that the threaded plate 11 moves more smoothly and will not tilt or shake.

[0039] In use, first adjust the supporting outer shell 2 and the supporting inner plate 3 according to the distance between the steel structure and the wall. During adjustment, unscrew the nut 23 and remove the screw 22. At this point, the supporting inner plate 3 and the supporting outer shell 2 are unlocked. Slide the supporting inner plate 3 relative to the supporting outer shell 2 until it reaches the appropriate position. Insert the screw 22, passing it through through holes one and two, and then tighten the nut 23 to lock the positions of the supporting outer shell 2 and the supporting inner plate 3. Then, adjust the connecting seat 6 by rotating it according to the angle between the steel structure and the wall. During adjustment, turn the adjusting bolt 25 until the adjusting bolt... When bolt 25 is unscrewed from the threaded groove and the threaded hole at the upper position, the locking toothed plate 28 unlocks and can slide. When the locking toothed plate 28 disengages from the locking toothed plate 15, it will compress the spring 27 and deform. At this time, the adjusting bolt 25 can be passed through the threaded hole at the lower position and screwed into the threaded groove to lock the position of the locking toothed plate 28. At this time, the rotation angle between the inner support plate 3 and the connecting seat 6 can be adjusted by rotating shaft 14. After adjustment, the adjusting bolt 25 is unscrewed. At this time, the elastic force of spring 27 will drive the locking toothed plate 28 to reset and engage with the locking toothed plate 15. The adjusting bolt is then tightened again. 25 passes through the threaded hole at the upper position and is screwed into the threaded groove to lock the position of the locking toothed plate 28. Then, depending on the surface shape of the steel structure, either the curved plate 19 or the flat plate 20 is selected. When selecting, the rotation of the rotating shaft 217 drives the mounting frame 18 to rotate, realizing the flipping and switching positions of the curved plate 19 and the flat plate 20 on both sides of the mounting frame 18. Then, the knob is turned to drive the bidirectional screw 10 to rotate, thereby driving the two threaded plates 11 to move away from each other. In turn, the hinge seat 12, hinge arm 13, and hinge seat 214 drive the mounting plates 15 on both sides to move away from each other. The mounting plate 16 drives the mounting frames 18 on both sides to move away from each other. Then, the adjusting shell 9 is placed facing the steel structure, so that the mounting frames 18 on both sides are located on both sides of the steel structure. The support plate 1 is installed to the wall using expansion screws. Then, the knob is rotated in the opposite direction to drive the bidirectional screw 10 to flip, thereby driving the mounting frames 18 on both sides to move closer to each other. This causes the arc-shaped clamping plate 19 or the flat clamping plate 20 on the mounting frame 18 to move to fit the surface of the steel structure. Then, the mounting bolt 21 is used to pass through the arc-shaped clamping plate 19 and the flat clamping plate 20 and connect to the steel structure to achieve stable support for the steel structure.
