[0002] The building pipe connection processing device is a specialized piece of equipment used in building engineering to achieve precise connection and processing of various pipes such as metal pipes, plastic pipes, and composite pipes during installation or maintenance. Through mechanized operation, it solves problems such as cutting, beveling, centering and fixing, welding or fusion assistance during pipe connection, ensuring the sealing, strength and stability of the pipe connection. It is widely used in building pipeline construction scenarios such as water supply and drainage, heating, gas, fire protection, and industrial pipelines.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing docking processing devices lack a structure to fix the metal pipes during the alignment process. This results in the pipes easily shifting due to slight external interference, such as touches from workers or vibrations at the construction site, leading to deviations during pipe alignment and welding.

[0004] To address this, a building pipe connection processing device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a building pipe connection processing device that can solve the problem that existing pipe connection methods lack a structure to fix the metal pipe during the alignment of building pipes. This results in the pipe being prone to displacement due to slight external interference, such as touch by workers or vibration at the construction site, which leads to deviations during pipe alignment and welding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building pipe docking processing device, comprising a movable plate, an alignment mechanism on the top of the movable plate, a limiting mechanism welded to the top of the alignment mechanism, the limiting mechanism comprising a lower placement plate, a rotating rod, a stepper motor, an upper closing plate, mounting holes, a pressure sensor, three limiting holes and an electromagnet, the lower placement plate being welded to the top of the alignment mechanism, the rotating rod being rotatably connected to the rear side of the lower placement plate, the stepper motor being respectively installed on the rear side of the right side of the left lower placement plate and the rear side of the left side of the right lower placement plate, the right side of the left rotating rod and the left side of the right rotating rod being connected to a connecting shaft via a flat key, the output end of the stepper motor penetrating the lower placement plate and fixedly connected to the side of the connecting shaft away from the rotating rod, and the upper closing plate being welded to the surface of the rotating rod.

[0007] Preferably, the mounting hole is opened on the inner side of the lower placement plate, the pressure sensor is installed on the inner side of the mounting hole, the limiting holes are respectively opened on both sides of the lower placement plate and both sides of the upper closing plate, and the electromagnet is installed on the inner side of the limiting hole.

[0008] Preferably, the alignment mechanism includes a moving groove, a rotating shaft, a lead screw, a servo motor, a threaded sleeve, and a support rod, with the moving groove located on the top of the moving plate.

[0009] Preferably, the rotating shaft is installed inside the moving slot, the lead screw is fixedly connected to both sides of the rotating shaft, the left side of the left lead screw is connected to the connecting rotating shaft by a flat key, and the servo motor is installed on the left side of the moving plate.

[0010] Preferably, the output end on the right side of the servo motor passes through the moving plate and is fixedly connected to the left side of the connecting shaft, the threaded sleeve is threadedly connected to the surface of the lead screw, the support rod is welded to the top of the threaded sleeve, and the lower placement plate is welded to the top of the support rod.

[0011] Preferably, the top and bottom of the support rod are welded with reinforcing rings, and the surface of the reinforcing rings is coated with an anti-corrosion coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The alignment mechanism of this application uses a servo motor to drive the lead screw to rotate, which in turn drives the threaded sleeve and the top support rod to move horizontally along the moving groove, thereby realizing the automatic approach and alignment of the pipes on both sides. Compared with manual alignment, mechanical transmission can control the moving distance, ensure the coaxiality of the pipe axis, and avoid misalignment caused by human operation error. The cooperation between the lead screw and the threaded sleeve can realize continuous and stable distance adjustment, which is suitable for the pipe docking needs of different lengths and diameters. There is no need to frequently change parts. The distance between the pipes on both sides can be flexibly adjusted by controlling the rotation direction and angle of the servo motor, thereby improving the adaptability of the device to diverse construction scenarios. 2. The limiting mechanism of this application uses a stepper motor to drive a rotating rod, which causes the upper closing plate and the lower placement plate to close, forming a clamping and fixing of the pipe. This prevents the pipe from shifting due to external forces such as contact or vibration during alignment or processing. The electromagnet in the limiting hole can generate an attraction force on the metal pipe, further enhancing the fixing effect. It is especially suitable for heavy or smooth metal pipes, solving the slippage problem that may occur with traditional mechanical clamping. The pressure sensor in the mounting hole can monitor in real time whether there is a metal pipe placed on the inside of the lower placement plate and transmit the data to the PLC controller. The PLC controller controls the stepper motor to open or close. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A building pipe docking processing device includes a movable plate 1. An alignment mechanism 2 is provided on the top of the movable plate 1. A limiting mechanism 3 is welded to the top of the alignment mechanism 2. The limiting mechanism 3 includes a lower placement plate 31, a rotating rod 32, a stepper motor 33, an upper closing plate 34, a mounting hole 35, a pressure sensor 36, three limiting holes 37, and an electromagnet 38. The lower placement plate 31 is welded to the top of the alignment mechanism 2. The rotating rod 32 is rotatably connected to the rear side of the lower placement plate 31. The stepper motor 33 is respectively installed on the rear side of the right side of the left lower placement plate 31 and the rear side of the left side of the right lower placement plate 31. The right side of the left rotating rod 32 and the left side of the right rotating rod 32 are connected to a connecting shaft by a flat key. The output end of the stepper motor 33 passes through the lower placement plate 31 and is fixedly connected to the side of the connecting shaft away from the rotating rod 32. The upper closing plate 34 is welded to the surface of the rotating rod 32.

[0019] In this embodiment: the movable plate 1 can support and limit the alignment mechanism 2. Simultaneously, a PLC controller is installed on the front side of the movable plate 1. The PLC controller can control the stepper motor 33, servo motor 24, and electromagnet 38. The lower plate 31 provides a stable support surface for the metal pipe, and its cooperation with the upper closing plate 34 forms a clamping space. The rotating rod 32 transmits the power of the stepper motor 33 to the upper closing plate 34, realizing its rotation and opening / closing around the lower plate 31. The stepper motor 33 provides power for the opening and closing of the upper closing plate 34 under the control of the PLC controller. The positioning of the upper closing plate 34 is achieved by controlling the rotation angle, replacing... Manual operation is employed, with the upper closing plate 34 and the lower placement plate 31 working together to form a ring-shaped clamping grip on the metal pipe. The position of the metal pipe is fixed by mechanical pressure. The mounting hole 35 provides installation space for the pressure sensor 36. The pressure sensor 36 monitors the pressure value between the metal pipe and the lower placement plate 31 in real time. The feedback data is transmitted to the PLC controller, which controls the stepper motor 33 to start, causing the upper closing plate 34 and the lower placement plate 31 to close. The limiting hole 37 provides an installation position for the electromagnet 38. The electromagnet 38 generates an electromagnetic attraction force on the metal pipe, forming a double fixation with the mechanical clamping, thereby improving the fixation strength of the metal pipe.

[0020] Specifically, such as Figure 2 , Figure 3 As shown, mounting holes 35 are opened on the inner side of the lower placement plate 31, pressure sensor 36 is installed on the inner side of mounting holes 35, limiting holes 37 are opened on both sides of the lower placement plate 31 and both sides of the upper closing plate 34 respectively, and electromagnet 38 is installed on the inner side of limiting holes 37.

[0021] Specifically, such as Figure 4 As shown, the alignment mechanism 2 includes a moving groove 21, a rotating shaft 22, a lead screw 23, a servo motor 24, a threaded sleeve 25, and a support rod 26. The moving groove 21 is located on the top of the moving plate 1.

[0022] Specifically, such as Figure 4 As shown, the rotating shaft 22 is installed inside the moving slot 21, the lead screw 23 is fixedly connected to both sides of the rotating shaft 22, and the left side of the lead screw 23 is connected to the connecting shaft by a flat key. The servo motor 24 is installed on the left side of the moving plate 1.

[0023] In this embodiment: the moving groove 21 provides guidance and limit for the movement of the threaded sleeve 25. The rotating shaft 22 connects the lead screws 23 on both sides and transmits power to ensure that the lead screws 23 on both sides rotate synchronously. The lead screws 23 convert the rotational motion of the servo motor 24 into the linear motion of the threaded sleeve 25. At the same time, the thread of the left lead screw 23 is set to clockwise and the thread of the right lead screw 23 is set to counterclockwise, so that the threaded sleeves 25 on both sides move towards or away from each other. The servo motor 24 can drive the left lead screw 23 to rotate through the connecting rotating shaft. The threaded sleeve 25 and the lead screw 23 cooperate to achieve linear motion, and transmit the power of the lead screw 23 to the support rod 26. The support rod 26 can drive the limiting mechanism 3 to move synchronously.

[0024] Specifically, such as Figure 4 As shown, the output end of the servo motor 24 on the right side passes through the moving plate 1 and is fixedly connected to the left side of the connecting shaft. The threaded sleeve 25 is threadedly connected to the surface of the lead screw 23. The support rod 26 is welded to the top of the threaded sleeve 25, and the lower plate 31 is welded to the top of the support rod 26.

[0025] Specifically, such as Figure 5 As shown, the top and bottom of the support rod 26 are welded with reinforcing rings 4, and the surface of the reinforcing rings 4 is coated with anti-corrosion paint.

[0026] In this embodiment: by setting a reinforcing ring 4, the connection strength between the support rod 26 and the threaded sleeve 25 and the lower placement plate 31 is enhanced; by setting an anti-corrosion coating, its weather resistance is improved and the service life of the reinforcing ring 4 is extended.

[0027] Specifically, such as Figure 5 As shown, a push rod 5 is welded to the rear side of the movable plate 1, and a protective sleeve 6 is fitted on the surface of the push rod 5. The surface of the protective sleeve 6 is engraved with anti-slip texture.

[0028] Specifically, such as Figure 5 As shown, a self-locking caster wheel 7 is fixedly connected to the chamfer at the bottom of the movable plate 1, and the surface of the self-locking caster wheel 7 is coated with anti-corrosion paint.

[0029] In this embodiment: by setting a push rod 5, a gripping component is provided for the movement of the movable plate 1, making it convenient for operators to push the device to the construction position; by setting a protective sleeve 6, the soft material of the protective sleeve 6 improves the grip comfort; by setting an anti-slip texture, the friction between the hand and the push rod 5 is increased to prevent slippage during pushing; by setting a self-locking universal wheel 7, the device can move and turn flexibly to adapt to the position adjustment needs of different construction sites; by setting an anti-corrosion coating, the durability of the self-locking universal wheel 7 in outdoor or humid environments is improved.

[0030] Working Principle: First, the operator pushes the moving plate 1 using push rod 5. The moving plate 1 moves to the construction position and locks itself via self-locking casters 7. Then, the operator places the two metal pipes to be connected onto the lower placement plates 31 on the left and right sides, respectively. Next, the operator controls the stepper motors 33 on both sides to start via the PLC controller. The stepper motors 33 drive the rotating rod 32 to rotate via the connecting shaft, thereby causing the upper closing plate 34 to flip and gradually close with the lower placement plate 31 to form an encircling space, initially clamping the metal pipes. Then, when the pressure sensor 36 inside the lower placement plate 31 detects that the contact pressure between the pipe and the plate has reached a preset value, it sends a signal to the PLC controller. The controller then stops the stepper motors 33 and simultaneously starts the electromagnet 38, using electromagnetic... The adsorption force forms a secondary fixation on the metal pipe. Then, the PLC controller controls the servo motor 24 to start. The servo motor 24 drives the left lead screw 23 to rotate through the connecting shaft. The rotating shaft 22 drives the lead screws 23 on both sides to rotate synchronously, so that the threaded sleeves 25 on both sides move towards each other along the moving groove 21. Through the support rod 26, the limiting mechanisms 3 on both sides and the fixed pipe move closer to each other. Finally, after the alignment is completed, the operator turns off the servo motor 24 through the PLC controller. The threaded sleeves 25 use the self-locking property of the lead screw 23 to keep the pipe position stable. The operator can then perform subsequent docking processing such as welding. After the processing is completed, the operator turns off the electromagnet 38 and reverses the start of the stepper motor 33 through the PLC controller to open the upper closing plate 34, release the fixation on the pipe, and complete the entire docking processing process.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
