[0002] When people are carrying out water conservancy construction, they often need to use pipes for laying and transportation. When the length of the pipe is not enough, people generally weld two pipes to meet people's needs.

[0003] When people weld pipes, they need to lift the pipes and then splice one end of the pipes together before they can perform the welding operation. However, the pipes used in water conservancy projects are long, and manual lifting requires a lot of manpower and time. In addition, manual work cannot control the position of the pipes well, which is prone to deviations, resulting in welding failure and waste of materials. Therefore, a pipe auxiliary fixing device for water conservancy construction that can splice pipes is designed. Summary of the Invention

[0033] like Figure 1-Figure 7As shown, the present invention provides a technical solution: an auxiliary fixing device for pipelines for water conservancy construction, comprising a pipeline body 4 and a base plate 1, characterized in that a positioning plate 11 is fixedly connected to the four corners of the top end of the base plate 1, a positioning hole is opened at the top end of the positioning plate 11, a fixing pin 12 is movably arranged in the positioning hole, and universal wheels 13 are arranged at the four corners of the bottom end of the base plate 1; a lifting mechanism 2 is arranged at the center of the top end of the base plate 1, for adjusting the height of the auxiliary fixing structure 3; the auxiliary fixing structure 3 is arranged on the top of the lifting mechanism 2, for auxiliary fixing of the pipeline body 4.

[0034] Specifically, the base plate 1 is made of Q235 steel plate with a thickness of 10mm to ensure sufficient strength and stability.

[0035] like Figures 1 to 7 As shown, the lifting mechanism 2 includes a mounting seat 20, a mounting groove 21 is opened at the top of the mounting seat 20, a slide rail 22 is connected to the mounting groove 21 by bolts, and two electric sliders 23 are slidingly provided on the outer wall of the slide rail 22, the top of the electric slider 23 is fixedly connected to a connecting block 24, the top center position of the connecting block 24 is fixedly connected to a hinge seat 25, the outer wall of the hinge seat 25 is hinged with a connecting rod 26, and the outer side of the other hinge seat 25 is hinged with a fixed rod 27, a connecting hole is opened at the center of the connecting rod 26 and the fixed rod 27, a fixed shaft is provided in the connecting hole, and the other end of the connecting rod 26 and the fixed rod 27 is hinged with a fixed seat 28.

[0036] Specifically, the mounting seat 20 is welded at the center of the top of the base plate 1. The depth of the mounting groove 21 is 30mm and the width is 40mm. It is used to install the slide rail 22. The slide rail 22 is a linear guide rail with a model of HIWINHGH20CA and a length of 200mm. It is fixed in the mounting groove 21 by bolts. The electric slider 23 slides with the slide rail 22. The electric slider 23 is provided with a drive motor and a transmission mechanism. The drive motor is a DC motor with a power of 24W. The sliding of the electric slider 23 is controlled by a controller. The connecting block 24 is fixed to the electric slider 23 by bolts, and the hinge seat 25 is welded to the center position of the top of the connecting block 24. The connecting rod 26 and the fixed rod 27 are both metal rods with lengths of 150mm and 180mm respectively. Hinge holes are provided at both ends. They are hinged to the hinge seat 25 and the fixed seat 28 through a fixed shaft. The diameter of the fixed shaft is 10mm and it is made of high-strength bolts to ensure the firmness of the connection. The fixed seat 28 is used to install the auxiliary fixing structure 3. A mounting hole is provided at the top and it is connected to the auxiliary fixing structure 3 by bolts.

[0037] like Figures 1 to 7 As shown, the auxiliary fixing structure 3 includes a fixing plate 29, a fixing groove is provided at the bottom end of the fixing plate 29, a guide rail 391 is provided in the fixing groove, and baffles 30 are provided at both ends of the guide rail 391, the baffles 30 are fixedly connected to the fixing plate 29, and a second electric slider 31 is provided on the outer wall of the guide rail 391 for relative sliding movement. A mounting block 32 is provided at the bottom end of the second electric slider 31, and a rack 35 is connected to the outer wall of one side of the mounting block 32 by bolts. A fixing block 33 is symmetrically installed on the top of the fixing plate 29, and one end of the fixing block 33 is bolted. A connecting plate 34 is installed, and a gear 36 is rotatably provided on the outer side near the bottom end of the connecting plate 34. The gear 36 is meshed with the rack 35. A rotating rod is provided at the center of the gear 36 and the top of the connecting plate 34. A pulley 37 is provided at the other end of the rotating rod. The pulleys 37 are connected by a belt 39, and a fixing clamp 38 is connected to the outer side of the pulley 37 on the top of the connecting plate 34 by bolts. An auxiliary plate 392 is provided on one side of the connecting plate 34, and the auxiliary plate 392 is located above the belt 39.

[0038] In the present application, the fixed plate 29 is rectangular and 8 mm thick. The fixing groove at the bottom is 20 mm deep and 30 mm wide. It is used to install the guide rail 391. The guide rail 391 is a linear guide rail with a model of HIWINHGH15CA and a length of 180 mm. The baffles 30 at both ends are fixed to the fixed plate 29 by bolts to limit the sliding range of the second electric slider 31. The second electric slider 31 slides with the guide rail 391. Its structure is similar to that of the electric slider 32. It has a built-in drive motor and transmission mechanism. The mounting block 32 is fixed to the second electric slider 31 by bolts. The rack 35 is welded to the outer wall of one side of the mounting block 32. The module of the rack 35 is 2 and the number of teeth is 30. The fixed block 33 is symmetrically mounted on the fixed plate The top of 29 is fixed by bolts, the connecting plate 34 is connected to the fixed block 33 by bolts, the gear 36 is installed on the outside of the connecting plate 34 near the bottom, and is rotatably connected to the connecting plate 34 through a bearing. The diameter of the pulley 37 is 50 mm, and the belt 39 is a synchronous belt, model HTD3M-120, which is used to connect the two pulleys 37 to achieve power transmission. In another embodiment of the present application, the fixing clamp 38 can be an arc-shaped clamp with an anti-slip rubber pad on the inside, which is fixed to the outside of the pulley 37 at the top of the connecting plate 34 by bolts, and is used to clamp the pipe body 4. The auxiliary plate 392 is an L-shaped plate, which is fixed to one side of the connecting plate 34 by bolts, and is located above the belt 39, and is used to make the belt 39 to prevent the belt 39 from sagging.

[0039] In this application, the device is provided with an independent electrical control system, including a controller, a power supply, switches and buttons, etc. The controller adopts a PLC controller, model Siemens S7-200SMART, which is used to control the drive motors of the electric slider 23 and the second electric slider 31, to realize the automatic control of the lifting mechanism 2 and the auxiliary fixed structure 3. The power supply is 220V AC, which is converted into 24V DC through a transformer to power the drive motor. The switches and buttons are set on the operation panel of the equipment to facilitate the operator to control the operation of the equipment.

[0040] The specific working process of the present invention is as follows: when the equipment needs to be moved to the construction location, the operator first steps on the brake release pedal of the universal wheel 13. At this time, the brake mechanism of the universal wheel 13 is locked, and the four universal wheels 13 can rotate freely. Since the vehicle-carrying capacity of a single universal wheel 13 is 50kg, the overall weight of the equipment is within a reasonable range. The operator can easily move the equipment by pushing the base plate 1. When the equipment reaches the designated construction location, the operator steps on the brake pedal of the universal wheel 13. The brake mechanism presses the brake pads on the axle of the universal wheel 13 through the lever principle, thereby locking the universal wheel 13 and preliminarily fixing the equipment to the ground. To further enhance the stability of the equipment, the operator needs to insert the fixing pin 12 into the positioning hole of the positioning plate 11. The positioning plate 11 and the base plate 1 are fixed by welding. The positioning hole has a diameter of 20mm and the fixing pin 12 has a diameter of 19.5mm. The two form a clearance of 0.5mm for easy insertion. The fixing pin 12 is 150 mm long, with a 25 mm diameter disc at the bottom that contacts the ground. The operator can tap the top of the fixing pin 12 with a hammer to embed the disc into the ground (if the ground is hard, a hole can be pre-drilled). This secures the base plate 1 to the ground and prevents the equipment from moving due to external forces during construction. To adjust the height of the auxiliary fixing structure 3 to accommodate the different installation positions of the pipes, the operator presses the "up" or "down" button on the control panel. The PLC controller (Siemens S7-200SMART) receives the signal and sends a command to the drive motor (24 V DC motor) of the lifting mechanism 2. Once the drive motor starts, it drives the electric slide 23 via a transmission mechanism to slide on the slide rail 22. The slide rail 22 is a HIWINHGH20CA model linear guide rail, installed in the mounting groove 21 of the mounting base 20. The groove 21 is 30 mm deep and 40 mm wide, ensuring a secure installation. A rolling friction pair is formed between the electric slider 23 and the slide rail 22 through a ball bearing assembly, with a friction coefficient as low as 0.08, allowing the electric slider 23 to slide smoothly. When the two electric sliders 23 slide inward or outward synchronously, they drive the connecting block 24 to move. The hinged seat 25 at the top of the connecting block 24 is hinged to the connecting rod 26 and the fixed rod 27, forming a parallelogram linkage mechanism. When the connecting block 24 moves, the connecting rod 26 and the fixed rod 27 rotate around the fixed axis. Because the fixed axis is installed in the connecting hole at the center of the connecting rod 26 and the fixed rod 27, and the lengths of the two are 150mm and 180mm respectively, this structural design ensures that the fixed seat 28 always remains horizontal during the lifting process, with a horizontal deviation of ≤1. The fixed seat 28 is connected to the auxiliary fixing structure 3 via bolts, thereby achieving precise height adjustment of the auxiliary fixing structure 3. The adjustment range can be determined by the length of the slide rail 22 and the stroke of the linkage mechanism. When fixing the pipe body 4, the operator first places the pipe in a preset position between the two fixing clamps 38.The pipe diameter parameter is then entered on the operation panel. The PLC controller calculates the travel distance of the second motorized slide 31 based on this parameter and issues a command to the drive motor of the auxiliary fixed structure 3. Once the drive motor is activated, it drives the second motorized slide 31 along the guide rail 391. Guide rail 391 is a HIWINHGH15CA linear guide mounted in a fixed groove in the fixed plate 29. Stoppers 30 at each end limit the sliding range of the second motorized slide 31, preventing it from sliding off the guide rail 391. As the second motorized slide 31 slides, it moves the mounting block 32 and the rack 35 welded to one side of it. Rack 35 has a module of 2 and 30 teeth, meshing with gear 36 (a transmission ratio of 1:1). Gear 36 is mounted on the outside of the connecting plate 34 and is rotatably connected via a bearing. When rack 35 moves, the drive gear 36 rotates, which in turn rotates the rotating rod at the center of gear 36, driving pulley 37. Pulley 37 has a diameter of 50 mm and is connected by an HTD3M-120 timing belt, ensuring synchronous rotation of the two pulleys 37. A retaining clamp 38 is bolted to the outside of the pulley 37 at the top of the connecting plate 34. This curved clamp 38 has a non-slip rubber pad on its inner side. As the pulley 37 rotates, the clamps 38 rotate with it, symmetrically moving toward the pipe body 4 until their curved inner surfaces fit snugly against the outer wall of the pipe. The non-slip rubber pad increases the friction between the clamps 38 and the pipe, ensuring a secure clamping force. The clamping force of the clamps 38 can be linearly adjusted within a range of 150-800N, depending on the pipe diameter, to meet the requirements for securing pipes with diameters ranging from DN50 to DN200.

[0041] The auxiliary plate 392 is fixed to one side of the connecting plate 34 and is located above the belt 39. Its function is to support the belt 39 and prevent the belt 39 from sagging due to gravity during the transmission process, thereby ensuring the stability and accuracy of the belt transmission.

[0042] To sum up: A pipeline auxiliary fixing equipment for water conservancy construction, comprising a pipeline body 4 and a base plate 1, characterized in that a positioning plate 11 is fixedly connected to the four corners of the top end of the base plate 1, a positioning hole is opened at the top end of the positioning plate 11, a fixing pin 12 is movably arranged in the positioning hole, and universal wheels 13 are arranged at the four corners of the bottom end of the base plate 1; a lifting mechanism 2 is arranged at the center of the top end of the base plate 1, for adjusting the height of the auxiliary fixing structure 3; the auxiliary fixing structure 3 is arranged at the top of the lifting mechanism 2, for auxiliary fixing of the pipeline body 4.

[0043] The lifting mechanism 2 is provided to facilitate height adjustment for fixing the pipe body 4. The slide rail 22 in the mounting seat 20 cooperates with the electric slider 23. The sliding of the electric slider 23 drives the connecting block 24 to move, thereby causing the hinged connecting rod 26 and the fixing rod 27 to move, thereby realizing the lifting and lowering of the fixing seat 28. Therefore, according to the pipeline installation height requirements in different construction scenarios, the height of the blocking fixed structure can be accurately adjusted to avoid installation difficulties caused by height discomfort and improve the applicability of the equipment.

[0044] At the same time, the setting of the auxiliary fixing structure 3 ensures the reliable fixation of the pipe body 4. The guide rail 391 in the fixing plate 29 cooperates with the second electric slider 31, so that the mounting block 32 can slide along the guide rail 391, driving the rack 35 to move, and the rack 35 engages with the gear 36. When the rack 35 moves, the gear 36 rotates, and the fixed clamp 38 is activated through the transmission of the rotating rod, pulley 37 and belt 39 to achieve clamping and fixation of the pipe, and fixation of pipes of different diameters, thereby enhancing the versatility of the equipment. At the same time, the symmetrically arranged fixing block 33, connecting plate 34 and gear 36 make the clamping force of the fixing clamp 38 on the pipe evenly distributed, ensuring the stability of the pipe fixation, preventing the pipe from shaking or displacement during construction, and ensuring the construction quality of the water conservancy project.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
