Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline laying technology, specifically to a fire protection pipeline laying device. Background Technology

[0002] With social development, large cities have dense populations and high-rise buildings. Laying fire-fighting pipelines is an essential operation to ensure building safety, and can greatly reduce the range of fire when a fire occurs.

[0003] For example, Chinese Patent (CN221991104U) discloses an auxiliary device for fire-fighting pipeline laying, relating to the technical field of pipeline laying auxiliary devices. This auxiliary device includes a supporting base plate, a drive motor, and a first clamping plate. A fixing frame is fixedly installed on the top of the supporting base plate, and a pipeline body is located on one side of the fixing frame; the drive motor is fixedly installed on the top of the fixing frame. This auxiliary device can lift and lower the pipeline body, allowing it to be moved to the installation position during installation without manual support, effectively reducing the labor intensity of workers. Furthermore, the rotating rod allows for adjustment of the pipeline body's angle, enabling horizontal, tilted, and even vertical installation, greatly expanding the device's applicability and practicality.

[0004] In existing technologies, fire-fighting pipes are clamped using telescopic springs. If the fire-fighting pipe is subjected to an external impact, the spring will deform. Once the spring is deformed, its elastic recovery ability may decrease, resulting in a weakening of the clamping force. This can cause the fire-fighting pipe to shift or loosen during the clamping process. To address the above problems, a fire-fighting pipe laying device is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fire-fighting pipeline laying device, which solves the problem that the current method of using telescopic springs to clamp fire-fighting pipelines can cause the springs to deform if the fire-fighting pipeline is subjected to external force. Once the springs are deformed, their elastic recovery ability may decrease, resulting in a weakening of the clamping force and causing the fire-fighting pipeline to shift or loosen during the clamping process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fire-fighting pipeline laying device, including an installation plate, a lifting frame fixedly connected to the right side of the upper surface of the installation plate, movable slide rails fixedly connected to both the left and right ends of the front side of the lifting frame, movable plates slidably connected to the front sides of the two sets of movable slide rails via sliding blocks, a rotating column rotatably connected to the upper center of the movable plate via a bearing, a rotating plate fixedly connected to the front side of the rotating column, clamping components fixedly connected to both the left and right ends of the front side of the rotating plate, and climbing racks fixedly connected to both the left and right ends of the rear side of the lifting frame.

A movable gear is fixedly connected to the end of each of the two transmission rods. The two movable gears mesh with two sets of climbing racks respectively.

[0009] Preferably, omnidirectional casters are fixedly installed at the four corners of the bottom surface of the mounting plate, and the omnidirectional casters are equipped with brakes.

[0010] Preferably, the clamping assembly includes a box body, the rear side of which is fixedly connected to the front side of the rotating plate, a first irregular gear is rotatably connected to the upper part of the box body, and a second irregular gear is rotatably connected to the lower part of the box body via a rotating shaft, the first irregular gear and the second irregular gear meshing with each other.

[0012] Preferably, a clamping servo motor for driving the first irregular gear to rotate is fixedly installed on the side of the box body, and the clamping servo motor has a built-in torque sensor.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model drives the first irregular gear to rotate through the clamping servo motor.

At the same time, the dual-axis reducer drives the moving gear to move along the climbing rack, driving the moving plate and the clamped pipe to rise and fall smoothly. It can accurately connect to the installation position at different heights, eliminating the need for manual lifting and reducing physical exertion. The drive motor drives the rotating column to rotate through the gearbox, which can realize the 360-degree rotation of the pipe, adapting to different laying angles such as horizontal, vertical, and inclined. Compared with traditional fixed angle devices, the adaptability is improved. Attached Figure Description

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1 - Figure 4 As shown, a fire-fighting pipeline laying device includes a mounting plate 1. A lifting frame 2 is fixedly connected to the right side of the upper surface of the mounting plate 1. Movable slide rails 3 are fixedly connected to both the left and right ends of the front side of the lifting frame 2. Movable plates 4 are slidably connected to the front sides of the two sets of movable slide rails 3 via sliding blocks. A rotating column 7 is rotatably connected to the upper center of the movable plate 4 via a bearing. A rotating plate 8 is fixedly connected to the front side of the rotating column 7. Clamping components 9 are fixedly connected to both the left and right ends of the front side of the rotating plate 8. Climbing racks 14 are fixedly connected to both the left and right ends of the rear side of the lifting frame 2. The movable slide rails 3 provide precise sliding guidance for the movable plate 4. The rotating column 7 drives the rotating plate 8 and the clamping components 9 at both ends to adjust the pipeline angle. The climbing rack 14 provides a meshing foundation for the movable gear 13. The overall structure is adapted to the lifting, angle adjustment and clamping requirements of fire-fighting pipeline laying, ensuring that the laying process is stable and controllable.

[0019] Reference Figure 4 As shown, a fixed base 5 is fixedly connected to the middle of the rear side of the movable plate 4. A gearbox 6 is fixedly connected above the fixed base 5. The rear end of the rotating column 7 is fixedly connected to the output end of the gearbox 6 through a coupling. A drive motor 10 is fixedly installed on the rear side of the gearbox 6 to serve as the power source for the gearbox 6. The drive motor 10 serves as the power source for the gearbox 6, thereby driving the rotating column 7 to drive the rotating plate 8 to rotate precisely, providing stable and controllable power for the angle adjustment after the pipe is clamped, and ensuring that the pipe angle adjustment is accurately adapted to the laying requirements.

[0020] Reference Figure 2 As shown, a dual-shaft reducer 11 is fixedly connected to the bottom of the fixed base 5. Both output ends of the dual-shaft reducer 11 are fixedly connected to transmission rods 12. The ends of the two transmission rods 12 are fixedly connected to moving gears 13. The two moving gears 13 mesh with two sets of climbing racks 14 respectively. The dual-shaft output design of the dual-shaft reducer 11 ensures that the force on both sides is balanced, realizing the smooth lifting and lowering of the moving plate 4, the rotating plate 8 and the clamping assembly 9. There is no deviation during the lifting and lowering process, which is suitable for fire pipeline laying scenarios of different heights.

[0021] Reference Figure 2 As shown, universal casters 15 are fixedly installed at the four corners of the bottom surface of the mounting plate 1. The universal casters 15 are equipped with brakes. The universal casters 15 have a built-in braking function, which not only facilitates the flexible movement of the device in the construction site to adapt to different laying positions, but also allows the wheels to be quickly locked by braking to prevent the device from shifting during the laying process, thus ensuring the safety and convenience of the operation.

[0022] Reference Figure 3As shown, the clamping assembly 9 includes a housing 901, the rear side of which is fixedly connected to the front side of the rotating plate 8. A first irregular gear 902 is rotatably connected to the upper part of the housing 901, and a second irregular gear 904 is rotatably connected to the lower part of the housing 901 via a rotating shaft. The first irregular gear 902 and the second irregular gear 904 mesh with each other. A first clamping rod 903 is fixedly connected to the front side of the first irregular gear 902, and a second clamping rod 905 is fixedly connected to the front side of the second irregular gear 904. The first irregular gear 902 and the second irregular gear 904 can drive the first clamping rod 903 and the second clamping rod 905 on the front side to open and close synchronously, so as to realize symmetrical clamping of the fire pipe, avoid uneven force on the pipe during clamping, and ensure the pipe clamping is stable.

[0023] Reference Figure 3 As shown, a clamping servo motor 906 for driving the first irregular gear 902 to rotate is fixedly installed on the side of the housing 901. The clamping servo motor 906 has a built-in torque sensor, which can be a JN2000G model. The clamping servo motor 906, the dual-axis reducer 11 and the gearbox 6 all have a self-locking function, so that the output end will not rotate freely even when the power is off.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0025] Working Principle: First, push the mounting plate 1 to move the device to the laying point via the universal casters 15. Brake the casters to secure the device. Manually place the fire-fighting pipe to be laid smoothly between the first clamping rod 903 and the second clamping rod 905 of the two clamping components 9, ensuring the pipe is centered. The clamping servo motor 906 drives the first irregular gear 902 to rotate, causing the second irregular gear 904 to rotate in the opposite direction. The first clamping rod 903 and the second clamping rod 905 close synchronously, gradually conforming to the pipe surface. When the torque sensor detects that the clamping force has reached the preset value, the clamping servo motor 906 stops rotating, the gear transmission structure locks the clamping force, and the pipe is securely fixed. The dual-shaft reducer 11 starts, and its output drives the two transmission rods 12 and the moving gear 13 to rotate synchronously. The moving gear 13 meshes with the climbing rack 14 on the rear side of the lifting frame 2, generating an upward driving force that drives the moving plate 4 to rise smoothly along the moving slide rail 3. The pipe rises synchronously with the moving plate 4. The pipe height is monitored in real time by manual observation. When the top of the pipe approaches the installation interface, the lifting speed is reduced until the pipe end face is precisely aligned with the installation interface. The dual-axis reducer 11 stops working, and the moving gear 13 engages and locks with the climbing rack 14, maintaining the pipe at its current height. If the installation interface is horizontal, the drive motor 10 starts, and after being reduced and increased in torque by the gearbox 6, it drives the rotating column 7 and the rotating plate 8 to rotate. The pipe rotates synchronously with the rotating plate 8. When the pipe rotates to be parallel to the installation interface, the drive motor 10 stops rotating, and the gearbox 6 locks the rotation angle, maintaining the pipe in its current posture for easy subsequent docking and installation. If the installation interface is vertical, the operation is the same. After the pipe is installed and fixed, the clamping servo motor 906 drives the clamping rod to open and detach from the pipe surface. The dual-axis reducer 11 reverses, driving the moving plate 4 and the clamping assembly 9 to descend to the initial height. The brakes on the universal moving wheels 15 are released, and the device is pushed away from the work point, completing the laying of a section of pipe.
