Description

Technical Field

[0001] This utility model relates to the field of building electromechanical installation, and in particular to a rolling processing device for fire-fighting pipeline docking groove with auxiliary pipe jacking function. Background Technology

[0002] During the installation of building fire protection pipelines, annular grooves need to be machined at their ends. These grooves allow for the connection of pipe fittings (such as clamps), effectively improving construction efficiency, especially suitable for large-scale fire protection pipeline system installations. Compared to traditional welding and threaded connections, this significantly shortens installation time. Furthermore, the use of grooving in conjunction with grooved fittings forms a reliable sealing connection. The rubber sealing ring inside the fitting, secured by the clamp, fits tightly against the groove in the pipe, effectively preventing fire water leakage and ensuring good sealing of the fire protection system during normal operation and emergencies, thus guaranteeing a normal supply of fire-fighting water. Currently, the annular grooves on pipe fittings are mainly processed by rolling using a grooving device. Grooving installation typically involves manually placing the fitting onto supporting rollers. During the grooving process, the fitting needs to be held horizontally, requiring a high level of operator experience and skill. Continuous processing is physically demanding and can easily lead to inconsistent annular groove processing quality, affecting the firmness and tightness of the pipe fitting connection. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a solution.

[0004] The technical solution of this utility model is: a rolling processing device for fire pipeline docking grooves with auxiliary pipe jacking function, including a geared motor, a hydraulic jack, a support wheel, and a lower pressure wheel. The hydraulic jack is equipped with a manual pressure rod, which controls the extension and retraction of the hydraulic jack. The geared motor is fixedly installed at one end of the rolling platform, and a vertical support bracket is provided at the other end of the rolling platform. A horizontal plate is provided at the upper end of the vertical support bracket, and the hydraulic jack is vertically mounted on the horizontal plate. The piston rod of the hydraulic jack extends downward from a through hole in the horizontal plate, and a [missing information - likely a device or component] is connected to the lower end of the piston rod. The U-shaped support has a pressure roller installed inside, allowing it to rotate freely. A seated bearing is located at the bottom of the vertical support, housing a drive shaft. One end of the drive shaft is connected to the output shaft of a geared motor via a coupling. A support wheel is installed at the other end of the drive shaft, directly below the pressure roller, and connected to the drive shaft via a key. An annular boss is located in the center of the outer surface of the pressure roller, and a corresponding annular groove is located in the center of the outer surface of the support wheel. The size of the annular groove is slightly larger than the size of the annular boss. A jacking mechanism is located at the end of the grooving platform.

[0005] Preferably, the jacking mechanism includes a jacking support, a linear push rod, a linear sliding sleeve, and a jacking plate. The telescopic push rod is located in the middle of the surface of the jacking support and is fixedly connected to the jacking support through a connecting plate and bolts. The linear sliding sleeve is connected to the jacking support through a T-shaped support and is welded and fixed to the jacking support. The telescopic rod of the linear push rod is slidably inserted into the linear sliding sleeve. The jacking plate is coaxially connected to the outer end of the telescopic rod and is coaxially corresponding to the support wheel.

[0006] Preferably, the inner end face of the support wheel is provided with a circular baffle, the diameter of which is larger than the diameter of the support wheel and the diameter of the corresponding fire-fighting pipe is larger than the pipe diameter.

[0007] Preferably, the surface of the push plate is provided with at least two coaxial mating frustums, and the size of the mating frustums increases progressively from the inside to the outside.

[0008] Preferably, the sides of the support wheels on both sides of the annular groove are provided with anti-slip textures, which are arranged in a crisscross pattern to form a grid.

[0009] Preferably, the vertical support bracket is an L-shaped plate, and a triangular reinforcing plate is provided between the vertical plate and the horizontal support plate of the L-shaped plate. The triangular reinforcing plate is welded and fixed between the vertical plate and the horizontal support plate.

[0010] The beneficial technical effects of this utility model are:

[0011] This invention features a circular baffle on the inner side of the support wheel, with a jacking plate on the jacking mechanism corresponding to the support wheel. The mating frustum on the jacking plate can be fitted onto the outer end of the pipe fitting. The jacking force of the linear push rod presses the pipe fitting firmly against the circular baffle. The jacking mechanism maintains the pipe fitting in a horizontal grooving state. The grooving process requires no manual assistance, solving the problem of the influence of operator skill and physical strength on the processing quality of the annular groove, and ensuring the stability of the grooving processing quality of fire-fighting pipelines.

Detailed Implementation

[0018] Example 1, see appendix Figure 3-4 A rolling processing device for fire-fighting pipeline 31 with auxiliary pipe jacking function includes a geared motor 11, a hydraulic jack 12, a support wheel 13, and a lower pressure wheel 14. The geared motor 11 is fixedly installed at one end of a rolling platform 16, and a vertical support bracket 15 is provided at the other end of the rolling platform 16. A horizontal plate 151 is provided at the upper end of the vertical support bracket, and the hydraulic jack 12 is vertically set on the horizontal plate 151. The hydraulic jack is a manual lever pressing type jack, which facilitates the operator to accurately control the pressure it generates on the lower pressure wheel 14. A U-shaped bracket 121 is connected to the lower end of the piston rod of the hydraulic jack 12, and the lower pressure wheel is installed in the U-shaped bracket. The hydraulic jack drives the U-shaped bracket 12 and the lower pressure wheel to move up and down synchronously. The jack 12 provides sufficient downward pressure to the pressure roller 14. The bottom of the vertical support bracket 15 is equipped with a seated bearing 152, and a drive shaft 17 is fitted inside the seated bearing. One end of the drive shaft 17 is connected to the output shaft of the geared motor 11 through a coupling 171. The support roller 13 is installed at the other end of the drive shaft 17 and is located directly below the pressure roller 14. The geared motor 11 transmits rotational power to the drive shaft 17 through the coupling 171, and the drive shaft rotates the support roller 13. The outer side of the pressure roller 14 is provided with an annular boss 141 in the middle, and the outer side of the support roller 13 is provided with an annular groove 131 in the middle. The annular boss 141 can be pressed down into the annular groove 131. The end of the grooving platform 16 is provided with a jacking mechanism.

[0019] The sides of the support wheels 13 on both sides of the annular groove 131 are provided with anti-slip textures 133. The anti-slip textures are used to increase the friction between the support wheels and the inner side of the fire pipe, and to improve the driving force of the support wheels 13 on the fire pipe 31.

[0020] The vertical support bracket 15 is an L-shaped plate. A reinforcing plate is provided between the vertical plate and the horizontal support plate of the L-shaped plate to increase the structural strength of the vertical support bracket 15 and ensure the stability of the hydraulic jack 12 groove.

[0021] Example 2, see appendix Figure 1-5This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the pipe jacking mechanism includes a pipe jacking support 21, a linear push rod 22, a linear sliding sleeve 23, and a jacking plate 24. The telescopic push rod is located in the middle of the surface of the pipe jacking support 21. The telescopic push rod is an electric push rod or a hydraulic cylinder push rod. The linear sliding sleeve 23 is connected to the pipe jacking support 21 through a T-shaped support 25. The telescopic rod 221 of the linear push rod 22 is slidably fitted into the linear sliding sleeve 23. The linear sliding sleeve provides sliding support for the telescopic rod, ensuring that it has sufficient support force for the fire-fighting pipeline 31. The jacking plate 24 is coaxially connected to the outer end of the telescopic rod 221, and the jacking plate 24 is coaxially corresponding to the support wheel 13.

[0022] The inner end face of the support wheel 13 is provided with a circular baffle 132. The diameter of the circular baffle is larger than the diameter of the support wheel. After the fire pipe 31 is fitted onto the support wheel 13, the circular baffle 132 blocks the port of the fire pipe 31, so that it is in the correct groove position.

[0023] The surface of the push plate 24 is provided with at least two coaxial docking frustums 241. The size of the docking frustums increases from the inside to the outside. The docking frustums 241 of different sizes are used to match the inner diameter of the fire pipes 31 of different specifications. The support wheel 13 is a quick-release structure. By replacing the support wheel 13 of different sizes, it can be matched with the fire pipes 31 of different specifications.

[0024] When using the processing device in this embodiment, the hydraulic jack 12 is manually operated to lift the lower pressure roller 14, leaving sufficient rolling space between the lower pressure roller 14 and the support roller 13. One end of the fire pipe 31 is fitted onto the lower pressure roller 14, and the other end is fitted onto the mating frustum 241 on the surface of the push plate 24. Then, the linear push rod 22 is activated to push the fire pipe 31 through the push plate 24, so that the fire pipe 31 is horizontally fitted between the circular baffle 132 and the push plate 24, avoiding jamming the fire pipe 31. The reduction motor 11 is activated to drive the support roller 13 to rotate through the drive shaft 17. The support roller 13 rotates the fire pipe 31 by friction, and then drives the piston rod of the hydraulic jack to extend downward. The lower pressure roller 14 moves downward and presses against the side wall of the pipe. The pressure of the hydraulic jack 12 presses the side wall of the pipe into the annular groove 131 on the support roller 13, realizing the rolling processing of the annular groove 131.
