[0002] With the increase of high-rise buildings in cities, the demand for the installation of fire-fighting pipes is increasing. The installation of fire-fighting pipes requires not only speed but also stability to ensure their effectiveness in emergency situations. Traditional installation methods often require a lot of manual operations, and the installation efficiency is low and the stability is insufficient.

[0003] Most of the existing fire protection pipe auxiliary devices are simple horizontal supports, which are difficult to meet the installation requirements of fire protection pipes in the vertical direction or other angles. For example, the "A Fire Protection Pipe Installation Support Device" proposed in patent announcement number CN109290763A includes a support plate, a groove plate, a first hollow tube, a second hollow tube and other structures. The invention supports the installation of the fire protection pipe through the groove plate, so that people do not need to use their hands to transport and support the fire protection pipe. However, the groove plate is installed horizontally and cannot be adjusted at an angle. When it is necessary to install a longitudinal fire protection pipe that passes through a floor, the device cannot support it, which is not convenient for assisting the fire protection pipe installation operation.

[0004] Therefore, we propose a support mechanism for fire protection pipe installation to solve the problems in the above background. Summary of the invention

[0030] Furthermore, the support frame 1 is a rectangular frame, a universal wheel is installed at the bottom of the support frame 1, and guide columns 2 are fixedly connected on both sides thereof, a lifting seat 3 is sleeved on the outside of the guide column 2, a threaded rod 4 is installed inside the lifting column, and a first motor 5 is fixedly connected to the rectangular frame, a rotating shaft of the first motor 5 is fixedly connected to one end of the threaded rod 4, the first motor 5 drives the threaded rod 4 to rotate, and drives the lifting seat 3 to slide up and down along the guide column 2 through the threaded rod 4.

[0031] Furthermore, the rotating assembly includes a toothed disc 6, a driving gear 7, and a second motor 8. The toothed disc 6 is rotatably connected to one end of the lifting seat 3, the driving gear 7 is meshed with the toothed disc 6, and the second motor 8 is fixedly mounted on the lifting seat 3. The second motor 8 drives the driving gear 7 to rotate, and the driving gear 7 drives the toothed disc 6 to rotate. The clamping assembly is mounted on the outer side of the toothed disc 6, and the rotating toothed disc 6 drives the clamping assembly to rotate, thereby adjusting the clamping assembly and the fire-fighting pipe clamped therein.

[0032] Furthermore, the clamping assembly includes a first clamping plate 9 and a second clamping plate 10. The first clamping plate 9 is fixedly connected to the toothed disc 6. An electric telescopic rod 11 is fixedly connected to the first clamping plate 9. The telescopic end of the electric telescopic rod 11 is fixedly connected to the second clamping plate 10. The second clamping plate 10 is moved closer to or away from the first clamping plate 9 by the extension and retraction of the electric telescopic rod 11. When the second clamping plate 10 and the first clamping plate 9 are away from each other, the fire-fighting pipe is placed on the first clamping plate 9, and then the second clamping plate 10 and the first clamping plate 9 are brought close to each other to clamp and fix the fire-fighting pipe, provide stable support for the fire-fighting pipe, and facilitate the installation of the fire-fighting pipe. After the installation is completed, the second clamping plate 10 and the first clamping plate 9 are separated, and the support frame 1 is moved to allow the fire-fighting pipe to exit the inside of the clamping assembly.

[0033] Embodiment 2:

[0034] See also Figure 1 ,2,4, and combined with Example 1, it is further obtained that a spacing adjustment component is installed between the rotating component and the clamping component, and the spacing adjustment component includes a guide rail 12, a reciprocating screw rod 13, and a third motor 14.

The two clamping components support both ends of the fire-fighting pipe to improve the stability of the support for the fire-fighting pipe.

[0035] Embodiment 3

[0036] See also Figure 1 , 2, 4, 5, and in combination with the first embodiment, the inner sides of the first splint 9 and the second splint 10 are provided with anti-slip grooves 15, the surface of the anti-slip grooves 15 is covered with an elastic rubber layer 16, and the elastic rubber layer 16 is embedded with a pressure sensor array 17. The support frame 1 is provided with a controller 18 that is communicatively connected to the pressure sensor array 17. The controller 18 dynamically adjusts the extension and retraction amount of the electric telescopic rod 11 according to the pressure distribution data to achieve adaptive clamping balance of the fire-fighting pipe.

[0037] An annular angle scale mark 19 is provided on the edge of the toothed disc 6, and a laser indicator 20 is fixedly mounted on the lifting seat 3. The light spot of the laser indicator 20 is projected onto the surface of the annular angle scale mark 19 to form an angle alignment mark. The second motor 8 is a servo motor and is connected to the controller 18 to realize digital and precise control of the rotation angle.

[0038] A hydraulic lifting leg 21 is provided at the universal wheel at the bottom of the support frame 1. The hydraulic lifting leg 21 is linked with the controller 18. When it is detected that the weight of the fire-fighting pipe exceeds a threshold, the leg is automatically deployed to lock the support frame 1. The deployment height of the hydraulic lifting leg 21 is directly proportional to the current height of the lifting seat 3, forming a height-center of gravity interlocking safety mechanism.

[0039] Working principle of the support mechanism for fire protection pipe installation:

[0040] The core of the support mechanism is a rectangular frame support frame 1, which ensures the stability of the support. The bottom is equipped with universal wheels for easy movement. Guide columns 2 are fixed on both sides of the support frame, and a lifting seat 3 is sleeved on the outside of the guide column 2. A threaded rod 4 is installed inside the lifting seat 3, and one end of the threaded rod 4 is fixedly connected to the rotating shaft of the first motor 5 on the support frame 1. When the first motor 5 rotates, the lifting seat 3 is driven to slide up and down along the guide column 2 through the threaded rod 4, so as to realize the lifting and lowering of the support frame 1 and the fire protection pipe. The toothed disc 6 of the rotating component is rotatably connected to one end of the lifting seat 3, and the driving gear 7 is meshed with the toothed disc 6. The second motor 8 is fixedly installed on the lifting seat 3. When the second motor 8 drives the driving gear 7 to rotate, the driving gear 7 drives the toothed disc 6 to rotate, and then drives the clamping component to rotate. The clamping component is arranged on the outside of the rotating component, and its first clamping plate 9 is fixedly connected to the toothed disc 6. The second clamping plate 10 is connected to the first clamping plate 9 through the electric telescopic rod 11. Through the extension and retraction of the electric telescopic rod 11, the second clamping plate 10 can be close to or away from the first clamping plate 9. When the fire-fighting pipe needs to be installed, the fire-fighting pipe is placed in the first clamping plate 9, and then the second clamping plate 10 is brought close to the first clamping plate 9 to clamp and fix the fire-fighting pipe. The clamping assembly is driven to rotate by the rotating assembly to adjust the angle of the clamping assembly and the fire-fighting pipe inside it. In this way, the fire-fighting pipe can be supported in the horizontal direction, vertical direction and at various inclined angles.

[0041] In the second embodiment, a spacing adjustment component is installed between the rotating component and the clamping component, including a guide rail 12, a reciprocating screw 13 and a third motor 14. The third motor 14 drives the reciprocating screw 13 to rotate, so as to adjust the distance between the two clamping components, thereby adjusting the support distance at both ends of the fire pipe and improving the support stability. The support mechanism for the installation of the fire pipe realizes the rapid, stable and flexible installation of the fire pipe through the coordinated work of the lifting, rotating and clamping components, thereby improving the installation efficiency.

[0042] In another embodiment, the improvement is to add a foldable cantilever beam (not shown in the figure) to the top of the support frame 1, which is connected to the top of the guide column 2 by a hinge, and can form a T-shaped support structure when unfolded. When dealing with extra-long fire-fighting pipes, auxiliary guide rails 12 and additional clamping components can be installed on both sides of the cantilever beam, and multi-point synchronous support can be achieved through the extended reciprocating screw 13. At this time, the first motor 5 adopts a dual output shaft design, and drives the threaded rods 4 on both sides to rise and fall at the same time through the coupling to ensure the synchronous movement of multiple groups of lifting seats 3. The diameter of the toothed disc 6 is increased accordingly and equipped with a double row of active gears 7 drive. The second motor 8 adopts a variable frequency motor to adapt to the torque requirements of pipes of different lengths. The hydraulic lifting legs 21 are increased to six and distributed radially. The controller 18 calculates the center of gravity of the pipeline and automatically adjusts the load-bearing ratio of each leg.

[0043] Another implementation method is to change the rotating assembly into a ball joint structure (not shown in the figure), replace the toothed disc 6 with a hemispherical shell with an internal gear, and change the driving gear 7 into a bevel gear to form a spatial transmission with the second motor 8. A ball joint seat is set on the back of the first clamping plate 9 of the clamping assembly, which can be arbitrarily deflected within the range of ±30°. The anti-slip pattern 15 adopts a bionic octopus suction cup structure, and an optical fiber strain sensor is buried in the elastic rubber layer 16 to replace the pressure sensor array 17. A gyroscope module is added inside the lifting seat 3. When the laser indicator 20 detects that the deflection of the annular angle scale mark 19 exceeds the limit, the controller 18 will link the hydraulic lifting leg 21 to make compensation adjustments to form a three-dimensional spatial posture stabilization system, which is particularly suitable for the precise installation of inclined pipelines.

[0044] Although specific embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the specific embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
