Description

Technical Field

[0001] The present application relates to the technical field of fire protection pipe installation, and in particular to an inner pipe support structure of a fire protection pipe. Background Art

[0002] Firefighting pipes are pipe systems used to transport firefighting water in buildings to implement firefighting and fire prevention measures, to transport firefighting water to the fire scene to control the spread of fire, and to provide water source guarantee for firefighting and to ensure the safety of personnel and buildings. In the process of laying firefighting pipes, firefighting pipes need to be buried underground.

[0003] When the existing fire protection pipe is buried underground, it is necessary to wrap the outside of the fire protection pipe with a protective layer for strengthening the protection of the fire protection pipe. The protective layer can slow down the erosion of the fire protection pipe, and a cavity is usually required between the fire protection pipe and the protective layer. Therefore, it is necessary to install a supporting structure between the fire protection pipe and the protective layer to separate the fire protection pipe from the protective layer. The existing supporting structure is composed of an asbestos mesh and cement mortar. The cement mortar and the asbestos mesh are cooled and formed between the fire protection pipe and the protective layer through a mold to form a supporting structure.

[0004] The above-mentioned prior art solutions have the following defects: the existing support structure is time-consuming and labor-intensive to install, which greatly affects the progress of fire protection pipeline installation. Utility Model Content

[0005] In order to make the fire protection pipe support structure more convenient to install, the present application provides a fire protection pipe inner pipe support structure.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] The inner pipe support structure of the fire protection pipeline includes a support ring, which is connected to the outer pipe. A plurality of clamping plates facing the center of the support ring are arranged inside the support ring. The clamping plates are connected to threaded rods, which are threadedly connected to the support ring.

[0008] By adopting the above solution, when installing the fire protection pipe, the support ring is set on the inner side of the outer pipe, and then the threaded rod is rotated to make the clamping plate clamp the inner pipe, so that the support ring supports between the inner pipe and the outer pipe, thereby achieving the purpose of making it easier for the support structure to be sleeved on the outside of the inner pipe.

[0009] Optionally, the clamping plate is a clamping plate with an arc-shaped surface, and the radius of the arc of the clamping plate is the same as the radius of the inner pipe of the fire protection pipe.

[0010] By adopting the above technical solution, the contact area between the pressing plate and the inner tube is increased, and the pressure on the inner tube is reduced, so that the inner tube is less likely to be damaged.

[0011] Optionally, a transmission bevel gear is rotatably connected inside the support ring, the axis of the transmission bevel gear and the diameter of the support ring are located on the same straight line, a threaded hole is opened in the center of the transmission bevel gear, the threaded rod is threadedly connected to the transmission bevel gear, and multiple transmission bevel gears are connected to the same circular ring, the circular ring and the support ring have the same axis, the circular ring is rotatably connected to the support ring, and a first bevel gear is arranged on the side of the circular ring close to the transmission bevel gear, and the first bevel gear is meshed with the transmission bevel gear.

[0012] By adopting the above technical solution, multiple transmission bevel gears can be driven to rotate by rotating the circular ring, so that the operator can simultaneously use multiple clamping plates to clamp the inner tube, which not only makes the installation of the support structure more convenient, but also enables the inner tube to be more accurately fixed in the center of the support ring.

[0013] Optionally, a square groove is formed at one end of the threaded rod away from the clamping plate, a square rod is arranged in the support ring along the radius of the support ring, one end of the square rod is fixedly connected to the support ring, the other end of the square rod is inserted into the square groove, and the square rod is slidably connected to the threaded rod.

[0014] By adopting the above technical solution, the threaded rod is prevented from rotating together with the transmission bevel gear, which causes the threaded rod to be unable to extend normally, thereby making the support structure more convenient to use.

[0015] Optionally, a gear ring is provided on the side of the circular ring away from the support tube, the gear ring is meshedly connected with the first spur gear, the first spur gear is connected to a wheel rod, and the end of the wheel rod away from the first spur gear passes through the support ring and is rotatably connected to the support ring.

[0016] By adopting the above technical solution, the operator can rotate the wheel rod to drive the first straight gear to rotate, thereby driving the ring to rotate, and then driving the transmission bevel gear to rotate, thereby driving the clamping plate to move, making it more convenient for the operator to install the support structure.

[0017] Optionally, the end of the wheel rod facing away from the first spur gear is fixedly connected with a knob.

[0018] By adopting the above technical solution, the operator can drive the wheel rod to rotate by turning the knob, thereby driving the driving gear and the ring to rotate, and then driving the transmission bevel gear to rotate, and then driving the clamping plate to move, making it more convenient for the operator to install the support structure.

[0019] Optionally, a rubber pad is provided on one side of the clamping plate close to the inner tube.

[0020] By adopting the above technical solution, there is a certain force buffer when the pressing plate and the inner pipe are pressed, and the rubber pad reduces the wear of the inner pipe, so that the service life of the fire-fighting pipe is extended.

[0021] In summary, this application has the following technical effects:

[0022] 1. By setting a support ring and a clamping plate, and threading the support ring with a threaded rod, it is more convenient to install the support structure;

[0023] 2. By setting up a circular ring and a transmission bevel gear, the operator can drive multiple threaded rods to move at the same time, making the installation of the support structure more convenient;

[0024] 3. The square rod is provided to prevent the threaded rod from rotating with the transmission gear. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 The fire-fighting pipe inner pipe support structure includes a support ring 1, and the support ring 1 is connected with a plurality of clamping plates 2, and the plurality of clamping plates 2 are arranged in a circumferential array, and the clamping plates 2 are connected with threaded rods 21, and the threaded rods 21 are threadedly connected with the support ring 1. The inner pipe 7 is a fire-fighting pipe, and the outer pipe 8 is a protective layer. When it is necessary to install the fire-fighting pipe inner pipe 7 support structure, the support structure is sleeved on the outer side of the inner pipe 7, and the support structure is set inside the outer pipe 8. When the support structure is set at the required support position, the threaded rod 21 is rotated to make the support rod rotate out in the support ring 1 until the clamping plates 2 are pressed against the surface of the inner pipe 7, and the above operation is repeated until all the clamping plates 2 are pressed against the surface of the inner pipe 7, so that the support structure is supported between the inner pipe 7 and the outer pipe 8.

[0031] Reference Figure 1 The clamping plate 2 is an arc-shaped plate. The arc-shaped clamping plate 2 increases the contact area with the inner tube 7, thereby reducing the pressure of the inner tube 7 and making the inner tube 7 less likely to be damaged. A rubber pad is provided on the side where the arc-shaped plate contacts the inner tube 7. The rubber pad provides a certain buffer for the force of the clamping plate 2 and the inner tube 7 when being clamped.

[0032] Reference Figure 2 and Figure 3 A ring-shaped transmission chamber 11 is provided in the support ring 1. A circular through hole is provided in the transmission chamber 11. The through hole connects the transmission chamber 11 with the inner ring of the support ring 1. A threaded rod 21 passes through the through hole. The end of the threaded rod 21 facing away from the clamping plate 2 is located in the transmission chamber 11. A transmission bevel gear 211 is rotatably connected in the transmission chamber 11. A threaded hole is provided in the middle of the transmission bevel gear 211. The threaded rod 21 is threadedly connected to the transmission bevel gear 211 through the threaded hole. A square rod 12 is fixedly provided in the transmission chamber 11. The square rod 12 faces the threaded rod 21. A square groove is provided at one end of the threaded rod 21 located in the through hole. The square rod 12 passes through the square groove, and the square rod 12 is slidably connected to the threaded rod 21. The transmission bevel gear 211 can be rotated relative to the threaded rod 21 by rotating the transmission bevel gear 211. At the same time, the square rod 12 limits the rotation of the threaded rod 21, so that the threaded rod 21 moves in the direction of retracting and extending the support rod.

[0033] Reference Figure 2 and Figure 3 An annular ring 3 is arranged in the transmission cavity 11. The axis of the ring 3 is the same as that of the support ring 1, and the ring 3 is rotatably connected in the transmission cavity 11. A first bevel gear 32 is arranged on the side of the ring 3 close to the transmission bevel gear thread. The first bevel gear 32 meshes with the transmission bevel gear 211. A toothed ring 31 is arranged on the side of the ring 3 away from the first bevel gear 32. The toothed ring 31 meshes with the first spur gear 4. The first spur gear 4 is fixedly connected with a wheel rod 41. The end of the wheel rod 41 away from the first spur gear 4 penetrates the support ring 1 to reach the outside of the support ring 1, and the wheel rod 41 is rotatably connected to the support ring 1. A knob 42 is fixedly arranged on one end of the wheel rod 41 located outside the support ring 1. When installing the support structure, the operator can rotate the knob 42 to drive the first spur gear 4 to rotate, thereby driving the ring 3 to rotate, thereby driving multiple transmission bevel gears 211 to rotate at the same time, thereby driving multiple threaded rods 21 to rotate out, so that multiple clamping plates 2 are simultaneously pressed against the surface of the inner tube 7. This makes it more convenient for operators to install the support structure, and multiple threaded rods 21 are extended simultaneously so that the inner tube 7 is always located in the center of the support ring 1.

[0034] The specific implementation principle of the present application is: when the support structure needs to be installed, the support ring 1 is placed between the inner tube 7 and the outer tube 8, and then the knob 42 is turned to drive the wheel rod 41 and the first straight gear 4 to rotate, thereby driving the ring 3 to rotate, thereby driving multiple transmission bevel gears 211 to rotate at the same time, thereby driving the threaded rod 21 to move toward the inner tube 7 until the clamping plate 2 is pressed against the surface of the inner tube 7, thereby fixing the support structure between the inner tube 7 and the outer tube 8. Compared with the existing support structure, the present support structure is easier to install.

[0035] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
