Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, specifically a fixing device for fire water pipelines in vertical storage tanks. Background Technology

[0002] Vertical storage tanks are important equipment for storing liquid media in industries such as petroleum and chemical engineering. Their fire safety is of paramount importance. Fire water pipeline systems, as key facilities for fire prevention and control of storage tanks, require stable and reliable fixed devices to ensure their normal operation in the event of a fire.

[0003] Currently, vertical storage tank fire water pipelines are commonly fixed with clamps. Traditional clamps are mostly fixed installations, and once the installation position is determined, it is difficult to change. In practical applications, when the storage tank is inspected or renovated, or when the layout of the fire water pipeline needs to be optimized, the fixed clamps cannot be flexibly repositioned. They can only be reinstalled by removing, re-welding, or drilling holes, which is not only cumbersome but also easily damages the storage tank body and anti-corrosion layer. When dealing with the installation requirements of fire water pipelines of different specifications and directions, the fixed clamps lack the flexibility of position adjustment and cannot meet the diverse actual engineering needs. Therefore, we propose a fixing device for vertical storage tank fire water pipelines. Utility Model Content

[0004] This utility model provides the following technical solution: a vertical storage tank fire water pipeline fixing device, comprising two arc-shaped plates, the two arc-shaped plates being connected by a fixing member, each of the two arc-shaped plates having an arc-shaped groove on its opposite side end, the arc-shaped groove having a T-shaped cross-section, a sliding plate being slidably connected in each of the two arc-shaped grooves, the two sliding plates having an I-shaped cross-section, the sliding plates being connected to the arc-shaped plates by a fixing member, a fixing clamp being fixedly installed on the outer end of each sliding plate, the fixing clamp having a pipe clamping member inside.

[0005] Preferably, the fixing component one includes multiple fixing plates, which are respectively fixedly installed on the side ends of the two arc-shaped plates. Each side end of the multiple fixing plates has a through hole, and two screw rods are slidably connected in the two opposite through holes. Two nuts are threadedly connected to the outer surface of the screw rods.

[0006] Preferably, the second fixing component includes an L-shaped plate, which is fixedly installed on the upper end of the sliding plate. A rod is slidably connected to the upper end of the L-shaped plate, and a limiting plate is fixedly installed on the outer surface of the rod. The upper surface of the arc-shaped plate is provided with multiple fixing grooves, which are arranged in an equidistant arc shape.

[0007] Preferably, the pipe clamping component includes a screw rod, which is threaded to the side end of the fixed clamp. One end of the screw rod extends into the interior of the fixed clamp. One end of the screw rod is connected to a clamping plate via a bearing. The clamping plate has an arc-shaped cross-section. A limit rod is fixedly installed on the side end of the clamping plate, and the limit rod extends to the outer end of the fixed clamp.

[0008] Preferably, a connecting spring is sleeved on the outer surface of the insertion rod, and the two ends of the connecting spring are respectively fixedly installed at the bottom end of the L-shaped plate and the upper end of the limiting plate.

[0009] Preferably, anti-slip pads two are fixedly installed on the opposite inner ends of the two arc-shaped plates, and anti-slip pads one is fixedly installed on the side end of the clamping plate. Both anti-slip pads one and two are made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model of fire-fighting pipeline fixing clamp can move along the periphery of the storage tank. When adjusting the pipeline position or performing maintenance and repair, there is no need to disassemble the clamp; simply slide the clamp to the appropriate position to complete the operation. This greatly reduces the workload of installation and maintenance, lowers the risk of damage to the storage tank body and anti-corrosion layer, improves maintenance efficiency and the service life of the storage tank. The movable clamp can slide freely along the periphery of the storage tank according to the actual installation requirements of the pipeline, and can be precisely adjusted in position. It can easily adapt to both large-diameter and small-diameter fire-fighting water pipelines, effectively meeting diverse engineering needs and enhancing the versatility and applicability of the fixing device.

Detailed Implementation

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a vertical storage tank fire water pipeline fixing device, including two arc-shaped plates 1, which are connected by a fixing component 1. Arc-shaped grooves 2 are opened on the opposite sides of the two arc-shaped plates 1. The cross-section of the arc-shaped grooves 2 is T-shaped. Sliding plates 3 are slidably connected in the two arc-shaped grooves 2. The cross-section of the two sliding plates 3 is I-shaped. The sliding plates 3 are connected to the arc-shaped plates 1 by a fixing component 2. A fixing clamp 4 is fixedly installed on the outer side of the sliding plate 3. A pipe clamping component is provided in the fixing clamp 4.

[0022] In an optional embodiment: the fixing component one includes multiple fixing plates 9, which are respectively fixedly installed on the side ends of two arc-shaped plates 1. Each side end of the multiple fixing plates 9 has a through hole 10 that is arranged in a through manner. A screw 11 is slidably connected in the two opposite through holes 10. Two nuts 12 are threadedly connected to the outer surface of the screw 11.

[0023] It should be noted that the two arc-shaped plates 1 are horizontally attached to the outer surface of the vertical tank. The diameter of the circle formed by the two arc-shaped plates 1 is matched with the outer diameter of the vertical tank. Then, the screw 11 is passed through the two corresponding through holes 10, and the through holes 10 are rotated so that the nut 12 is tightly attached to the outer wall of the fixing plate 9, thereby fixing the two arc-shaped plates 1 to the outer surface of the vertical tank.

[0024] In an optional embodiment: the second fastener includes an L-shaped plate 13, which is fixedly installed on the upper end of the sliding plate 3. The upper end of the L-shaped plate 13 is slidably connected to a rod 14. A limit plate 15 is fixedly installed on the outer surface of the rod 14. The upper surface of the arc plate 1 is provided with a plurality of fixing grooves 17, which are arranged in an equidistant arc shape.

[0025] It should be noted that by inserting the plug 14 into the corresponding fixing slot 17, the position of the sliding plate 3 can be fixed, thereby fixing the position of the pipe. When it is necessary to move the pipe later, the plug 14 can be pulled out from the fixing slot 17 for movement.

[0026] In an optional embodiment: the pipe clamping component includes a screw 6, which is threaded to the side end of the fixing clamp 4. One end of the screw 6 extends into the interior of the fixing clamp 4. One end of the screw 6 is connected to a clamping plate 5 via a bearing. The clamping plate 5 has an arc-shaped cross-section. A limit rod 20 is fixedly installed on the side end of the clamping plate 5, and the limit rod 20 extends to the outer end of the fixing clamp 4.

[0027] It should be noted that rotating screw 6 in both directions causes it to move to the left or right, which in turn causes clamping plate 5 to move to the left or right, thereby pressing pipes of different diameters against the inner wall of clamping clamp 4 and the side end of clamping plate 5 to achieve a fixing effect.

[0028] In an optional embodiment: a connecting spring 16 is sleeved on the outer surface of the insertion rod 14, and the two ends of the connecting spring 16 are respectively fixedly installed at the bottom end of the L-shaped plate 13 and the upper end of the limiting plate 15.

[0029] It should be noted that the stiffness and preload of the connecting spring 16 can be adjusted according to actual needs, so that the insertion rod 14 will not be difficult to operate due to excessive resistance when inserted, and can provide sufficient holding force after insertion to ensure that the insertion rod 14 will not easily come out.

[0030] In an optional embodiment: anti-slip pad 2 18 is fixedly installed on the opposite inner ends of the two arc plates 1, and anti-slip pad 1 8 is fixedly installed on the side end of the clamping plate 5. Both anti-slip pad 1 8 and anti-slip pad 2 18 are made of rubber.

[0031] It should be noted that the rubber material itself has good elasticity and friction, which can increase the coefficient of friction between the pipe or curved plate 1 and the contact surface.

[0032] In an optional embodiment: each of the two arc-shaped plates 1 is provided with a limiting block 19 at its bottom end, and the limiting block 19 is installed on the outer surface of the vertical tank by welding.

[0033] It should be noted that the limiting block 19 supports the arc plate 1, preventing the nut 12 from loosening over a long period of time, which would reduce the fastening effect of the arc plate 1 and cause it to slide downwards. Welding is less damaging to the vertical tank than fixing it by drilling holes on the surface of the vertical tank.

[0034] In an optional embodiment: a handle 7 is fixedly installed on the side end of the screw 6, and the outer surface of the handle 7 is provided with multiple protrusions.

[0035] It should be noted that the screw 6 is rotated by turning the handle 7, and the protrusions on it can increase the friction between the screw and the person turning it, thus preventing slippage during rotation.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] Two arc-shaped plates 1 are horizontally attached to the outer surface of the vertical tank, with the diameter of the circle formed by the two arc-shaped plates 1 matching the outer diameter of the vertical tank. Then, screw 11 is passed through the two corresponding through holes 10, and the through holes 10 are rotated to make the nut 12 fit tightly against the outer wall of the fixing plate 9, thereby fixing the two arc-shaped plates 1 to the outer surface of the vertical tank. The pipe is passed through the fixing clamp 4, and screw 6 is rotated in both directions. Screw 6 moves to the left or right, thereby causing the clamping plate 5 to move to the left or right, thus pressing the pipes of different diameters against the inner wall of the fixing clamp 4 and the side end of the clamping plate 5, achieving a fixing effect. Then, by pushing the sliding plate 3 in both directions, the position of the fixing clamp 4 on the outside of the vertical tank can be changed. After determining the position, insert rod 14 is inserted into the corresponding fixing groove 17 to fix the position of the sliding plate 3, thereby fixing the position of the pipe. When it is necessary to move the pipe later, the insert rod 14 can be pulled out from the fixing groove 17 for movement.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
