Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire protection pipe installation, in particular to a supporting device for fire protection pipe installation. Background Art
[0002] In the field of fire protection pipe installation, traditional support devices mostly use rigid clamps, U-shaped frames or welded fixed structures. The pipe installation needs to be completed through steps such as lifting, manual alignment and temporary fixation. There are some technical defects. For example, after the fire protection pipe is mounted on the support device, the fire protection pipe needs to be pushed to connect with the adjacent fire protection pipe. Since the fire protection pipes are currently installed on clamps or U-shaped frames, it is difficult to move the fire protection pipes and may damage the surface coating of the pipes. At the same time, the support used for the current installation of fire protection pipes lacks effective shock absorption design, which makes the fire protection pipes prone to fluid impact vibration, resulting in the hidden danger of large internal stress in the fire protection pipes.
[0003] Therefore, it is necessary to provide a new fire protection pipe installation support device to solve the above technical problems. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a support device for installing a fire protection pipe.
[0005] The support device for installing a fire protection pipe provided by the utility model comprises a U-shaped bottom plate, a U-shaped pressing plate rotatably connected is mounted on the U-shaped bottom plate, a plurality of equally spaced and rotatably connected guide rollers are mounted inside the U-shaped pressing plate, an arc portion is provided inside the U-shaped pressing plate, and a plurality of annularly distributed mounting holes are opened on the arc portion, and an abutment member is mounted in each of the mounting holes;
[0006] The abutting member includes a sliding column, which is inserted into the mounting hole and elastically connected to the mounting hole, and a column head of the sliding column extends out of the mounting hole and is embedded with a rotatably connected steel ball.
[0007] Preferably, the abutment member further comprises a spring, one end of the spring is fixedly connected to the insertion end of the sliding column, and the other end of the spring is fixedly connected to the inner top wall of the mounting hole.
[0008] Preferably, two symmetrically distributed rotating support frames are fixedly mounted on the U-shaped bottom plate, two symmetrically distributed rotating connecting plates are fixedly mounted on the U-shaped pressing plate, and the rotating connecting plates are rotatably connected to the corresponding rotating support frames via a rotating shaft.
[0009] Preferably, a through cavity is provided on the plate surface of the U-shaped pressing plate close to the rotating connecting plate.
[0010] Preferably, a plurality of symmetrically distributed hanging plates are fixedly mounted on the U-shaped bottom plate, and a plurality of waist-shaped holes equidistantly distributed up and down are opened on the hanging plates, and a fixing ear piece is fixedly mounted on each of the hanging plates.
[0011] Preferably, a limiting groove is provided on a side of the upper surface of the U-shaped pressing plate away from the rotating connecting plate.
[0012] Preferably, bolts for pressing the U-shaped pressing plates are inserted into the two symmetrically distributed hanging plates.
[0013] Compared with the related art, the fire protection pipe installation support device provided by the present invention has the following beneficial effects:
[0014] 1. The equidistant guide rollers installed in the U-shaped bottom plate of this utility model replace traditional sliding friction with rolling friction, significantly reducing the resistance when inserting the fire pipe. The fire pipe can slide linearly along the guide rollers and cooperate with the U-shaped pressing plate for rapid positioning, which is simple and convenient to operate and improves installation efficiency.
[0015] 2. In the present invention, when the fire protection pipe conveying water vibrates, the springs in each abutment can effectively absorb part of the vibration internal stress of the fire protection pipe, thereby effectively reducing the amplitude of the fire protection pipe. The steel balls connected in rotation on the sliding column can convert the radial friction force of the fire protection pipe into rolling friction. At the same time, the steel balls form point contact with the surface of the fire protection pipe, dispersing the traditional surface contact pressure into multiple point loads, avoiding local stress concentration that causes damage to the coating and scratches on the fire protection pipe surface, while allowing the fire protection pipe to undergo micro-displacement due to thermal expansion and contraction.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0026] See also Figures 1 to 7 The embodiment of the present invention provides a support device for installing a fire-fighting pipe, which includes a U-shaped bottom plate 1, a U-shaped pressing plate 2, a guide roller 3 and an abutment member 4.
[0027] In the embodiments of the present invention, please refer to Figures 1 to 7 A U-shaped pressing plate 2 with a rotatable connection is installed on the U-shaped bottom plate 1. Specifically, two symmetrically distributed rotating support frames 11 are fixedly installed on the U-shaped pressing plate 2. Two symmetrically distributed rotating connecting plates 21 are fixedly installed on the U-shaped pressing plate 2, and the rotating connecting plates 21 are rotatably connected to the corresponding rotating support frames 11 through a rotating shaft. A plurality of symmetrically distributed hanging plates 12 are fixedly installed on the U-shaped bottom plate 1, and a plurality of waist-shaped holes 12a equidistantly distributed up and down are opened on the hanging plate 12, and a fixed ear piece 13 is fixedly installed on each hanging plate 12;
[0028] A plurality of equally spaced and rotatably connected guide rollers 3 are installed in the U-shaped base plate 1, an arc-shaped portion 22 is provided in the U-shaped pressing plate 2, and a limiting groove 2c is provided on the side of the upper surface of the U-shaped pressing plate 2 away from the rotating connecting plate 21, and bolts 5 for pressing the U-shaped pressing plate 2 are inserted on the two symmetrically distributed lifting plates 12.
[0029] It should be noted that: the fixing ear piece 13 is fixed and hoisted on the ceiling in the house with screws, and then the U-shaped pressed plate 2 is rotated to drive the U-shaped pressed plate 2 and the U-shaped bottom plate 1 to be 90°, and then the fire-fighting pipe is inserted forward along the guide roller 3, and then the U-shaped pressed plate 2 is rotated to drive the arc-shaped portion 22 on the U-shaped pressed plate 2 to cover the upper side of the fire-fighting pipe, and the bolt 5 is passed through the waist-shaped hole 12a corresponding to the hanging plate 12 and the limit groove 2c opened on the U-shaped pressed plate 2, thereby driving the U-shaped pressed plate 2 and the U-shaped bottom plate 1 to cooperate with each other and tightly press the fire-fighting pipe.
[0030] The equidistant guide rollers 3 arranged in the U-shaped bottom plate 1 replace the traditional sliding friction with rolling friction, which significantly reduces the resistance when the fire pipe is inserted. The fire pipe can slide linearly along the guide rollers and cooperate with the U-shaped pressing plate 2 for rapid positioning. The operation is simple and convenient and improves the installation efficiency.
[0031] Furthermore, a through cavity 2a is opened on the plate surface of the U-shaped pressed plate 2 near the rotating connecting plate 21. When the U-shaped pressed plate 2 is at 90° to the U-shaped bottom plate 1, the through cavity 2a designed on the U-shaped pressed plate 2 allows the fire-fighting pipe to be smoothly inserted into the guide roller 3 on the U-shaped bottom plate 1.
[0032] In the embodiments of the present invention, please refer to Figures 1 to 7 The arc-shaped portion 22 is provided with a plurality of annular mounting holes 2b, and an abutment member 4 is installed in each mounting hole 2b. The abutment member 4 includes a sliding column 41, which is inserted into the mounting hole 2b and elastically connected to the mounting hole 2b, and the column head of the sliding column 41 extends out of the mounting hole 2b and is embedded with a rotatably connected steel ball 42. The abutment member 4 also includes a spring 43, one end of the spring 43 is fixedly connected to the inserted end of the sliding column 41, and the other end of the spring 43 is fixedly connected to the inner top wall of the mounting hole 2b.
[0033] It should be noted that: after the arc-shaped portion 22 on the U-shaped pressing plate 2 covers the upper tube body of the fire-fighting pipe, the steel ball 42 at the end of the sliding column 41 is driven to abut against the fire-fighting pipe under the action of the spring 43. When the fire-fighting pipe transports water and vibrates, the spring 43 in each abutting part 4 can effectively absorb part of the vibration internal stress of the fire-fighting pipe, thereby effectively reducing the amplitude of the fire-fighting pipe, and the steel ball 42 rotatably connected to the sliding column 41 can convert the radial friction force of the fire-fighting pipe into rolling friction. At the same time, the steel ball 42 forms point contact with the surface of the fire-fighting pipe, dispersing the traditional surface contact pressure into multiple point loads, avoiding local stress concentration leading to damage to the coating and scratches on the surface of the fire-fighting pipe, while allowing the fire-fighting pipe to undergo micro-displacement due to thermal expansion and contraction.
[0034] It is worth noting that the steel ball 42 can automatically adjust the contact angle according to the curvature of the fire pipe surface, ensuring that the sliding column 41 always maintains a vertical force state with the fire pipe.
[0035] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
