Description

Technical Field

[0001] This utility model belongs to the field of support device technology, specifically a pipeline support device for water conservancy projects. Background Technology

[0002] In water conservancy projects, pipelines are the core facilities for water resource transportation, flood control and drainage. Their laying involves various complex terrains such as mountains and depressions, which puts forward higher requirements for the terrain adaptability, pipe diameter compatibility and long-term stability of the support devices. The performance of the support devices directly determines the leakage rate and service life of the pipeline system.

[0003] Currently, the mainstream pipe support devices in the industry are mainly divided into two categories: one is concrete fixed supports, which are connected to the foundation through on-site casting. Although they have strong load-bearing capacity, their structure is fixed and heavy, and the angle cannot be adjusted. When facing changes in terrain slope, the size needs to be customized, and the construction cycle is long (2-3 days for a single set of installations); the other is steel sliding supports, which are welded from standardized steel sections. Although they are lighter, they are mostly pre-sized and only fit a single pipe diameter. The support angle cannot be adjusted, and steel supports are difficult to be compatible with multiple pipe specifications, which can easily lead to pipe axis misalignment and cause interface sealing failure. Therefore, a new type of pipe support device for water conservancy projects is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a pipeline support device for water conservancy projects is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water conservancy engineering pipeline support device, comprising a fixed frame; the inner side wall of the fixed frame is rotatably connected to an adjusting plate via a rotating shaft; The fixed frame is equipped with an adjustment mechanism, which includes a fixed groove formed in the bottom wall of the fixed frame. A drive tube is slidably connected in the fixed groove. One end of the drive tube has a threaded hole, and a lead screw is threaded into the threaded hole. One end of the lead screw extends out of the threaded hole and is rotatably connected to the inner side wall of the drive groove through a connecting ring. A toggle rod is fixedly connected to the end of the lead screw near the connecting ring. The other end of the toggle rod passes through the fixed frame and communicates with the outside. A hinge rod is hinged to the outer wall of the drive tube. The other end of the hinge rod is rotatably connected to an adjustment plate. The adjustment mechanism allows for easy rotational adjustment of the angle of the adjustment plate, facilitating stable support for pipes with different inner diameters.

[0006] Preferably, a baffle plate is fixedly connected to the inner side wall of the fixing groove, and the bottom end of the baffle plate abuts against the drive pipe. By setting the baffle plate, the exposed screw rod can be easily covered, so as to avoid debris and dirt generated during the pipeline installation process from adhering to the outer wall of the screw rod and affecting the rotation of the screw rod.

[0007] Preferably, a knob is fixedly connected to one end of the hinge rod located on the outside. The outer wall of the knob is provided with anti-slip texture, and the screw can be rotated by rotating the knob.

[0008] Preferably, a protective ring is fixedly connected to one side of the fixing frame near the knob, and the other end of the protective ring abuts against the knob, thereby shielding the part of the lead screw located outside the fixing frame.

[0009] Preferably, a first gear is fixedly connected to the outer wall of the protective ring on the actuating rod, and an inner gear is slidably connected inside the protective ring. The inner gear abuts against the first gear. A spring is sleeved on the outer wall of the protective ring on the actuating rod. An actuating block is fixedly connected to one side of the outer wall of the inner gear. An actuating groove is formed on one side of the outer wall of the protective ring. One end of the actuating block extends out of the actuating groove. Through the arrangement of the first gear, the inner gear, the spring, the actuating groove, and the actuating block, it is convenient to limit the rotation of the lead screw and ensure the positioning of the rotation angle of the adjusted plate after adjustment.

[0010] Preferably, a blocking block is fixedly connected to one end of the actuating block located on the outside. A sealing gasket is provided on the side of the blocking block near the actuating block. The actuating block can be moved by pulling the blocking block and the actuating groove can be blocked.

[0011] Preferably, an auxiliary frame is fixedly connected to the side of the adjusting plate away from the hinge rod, and a roller is rotatably connected to the inner side wall of the auxiliary frame. The auxiliary frame and roller facilitate the translation of the supported pipe.

[0012] Preferably, assembly blocks are fixedly connected to both sides of the fixing frame, and assembly holes are provided on both sides of the fixing frame. By setting the assembly blocks, the two fixing frames can be assembled, which facilitates the support and positioning of the pipeline.

[0013] The beneficial effects of this utility model are: This utility model provides a pipeline support device for water conservancy projects. The adjustable mechanism allows for easy rotational adjustment of the adjustment plate angle, facilitating stable support for pipelines of different inner diameters. Rotating the knob drives the lead screw to rotate. Because the lead screw is threadedly connected to the threaded hole of the drive pipe, the drive pipe slides directionally along the fixed groove. The hinge rod pushes the adjustment plate to rotate around the axis, achieving flexible adjustment of the support angle. After adjustment, the spring resets, pushing the internal gear to mesh with the first gear, limiting the lead screw's position. A shielding plate and a protective ring respectively shield the lead screw portion inside and outside the fixed groove, preventing debris adhesion. The shielding block, in conjunction with a sealing gasket, seals the actuation groove for further protection. Rollers on the auxiliary frame reduce friction between the pipeline and the support surface, facilitating pipeline translation and adjustment. The assembly block allows for the splicing of multiple devices through assembly holes, increasing support strength. Attached Figure Description

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-6 This utility model provides a water conservancy engineering pipeline support device, which includes a fixed frame 1; the inner side wall of the fixed frame 1 is rotatably connected to an adjusting plate 2 via a rotating shaft; An adjustment mechanism 3 is provided inside the fixed frame 1. The adjustment mechanism 3 includes a fixed groove 31 formed in the bottom wall of the fixed frame 1. A drive tube 32 is slidably connected in the fixed groove 31. One end of the drive tube 32 has a threaded hole 33. A lead screw 34 is threadedly connected in the threaded hole 33. One end of the lead screw 34 extends out of the threaded hole 33 and is rotatably connected to the inner side wall of the drive groove through a connecting ring. A toggle rod 35 is fixedly connected to the end of the lead screw 34 near the connecting ring. The other end of the toggle rod 35 passes through the fixed frame 1 and communicates with the outside. A hinge rod 36 is hinged to the outer wall of the drive tube 32. The other end of the hinge rod 36 is rotatably connected to the adjustment plate 2. With the setting of the adjustment mechanism 3, the angle of the adjustment plate 2 can be easily adjusted by rotation, which facilitates stable support operation for pipes with different inner diameters.

[0019] A baffle plate 4 is fixedly connected to the inner wall of the fixed groove 31. The bottom end of the baffle plate 4 abuts against the drive tube 32. The baffle plate 4 can be used to cover the exposed screw rod 34, so as to prevent debris and dirt generated during the pipeline installation from adhering to the outer wall of the screw rod 34 and affecting the rotation of the screw rod 34.

[0020] A knob 5 is fixedly connected to one end of the hinge rod 36 located on the outside. The outer wall of the knob 5 is provided with anti-slip texture. The screw 34 can be rotated by rotating the knob 5.

[0021] A protective ring 6 is fixedly connected to one side of the mounting bracket 1 near the knob 5. The other end of the protective ring 6 abuts against the knob 5, and the protective ring 6 blocks the part of the lead screw 34 located outside the mounting bracket 1.

[0022] A first gear 7 is fixedly connected to the outer wall of the actuating rod 35 inside the protective ring 6. An inner gear 8 is slidably connected inside the protective ring 6, and the inner gear 8 abuts against the first gear 7. A spring 9 is sleeved on the outer wall of the actuating rod 35 inside the protective ring 6. An actuating block is fixedly connected to one side of the outer wall of the inner gear 8. An actuating groove is opened on one side of the outer wall of the protective ring 6. One end of the actuating block extends out of the actuating groove. Through the arrangement of the first gear 7, the inner gear 8, the spring 9, the actuating groove, and the actuating block, it is convenient to limit the rotation of the lead screw 34 and ensure the positioning of the rotation angle of the adjusted plate 2 after adjustment.

[0023] A blocking block 10 is fixedly connected to one end of the actuating block located on the outside. A sealing gasket is provided on the side of the blocking block 10 near the actuating block. The actuating block can be moved by pulling the blocking block 10 and the actuating groove can be blocked.

[0024] An auxiliary frame 11 is fixedly connected to the side of the adjusting plate 2 away from the hinge rod 36. A roller is rotatably connected to the inner wall of the auxiliary frame 11. The auxiliary frame 11 and the roller facilitate the translation of the supported pipe.

[0025] Assembly blocks 12 are fixedly connected to both sides of the fixed frame 1. Assembly holes are opened on both sides of the fixed frame 1. The two fixed frames 1 can be assembled by setting the assembly blocks 12, which facilitates the support and limiting of the pipeline.

[0026] Based on the above structural configuration, this utility model includes the following implementation process: First, based on the foundation type at the water conservancy project site—concrete foundation, soft soil foundation, or mountain rock foundation—prepare the installation foundation for the fixing frame 1. If it is a pre-cast concrete foundation, pre-drill installation holes with a diameter matching M16-M20 expansion bolts and a depth ≥80mm on the foundation surface corresponding to the bottom of the fixing frame 1. If it is a soft soil foundation, excavate a pit with a depth ≥300mm, pour C30 precast concrete blocks with a size not less than 300mm×300mm×200mm in the pit, and drill installation holes on the surface of the precast blocks after the concrete strength reaches the standard. If it is a mountain rock foundation, use a rock drilling machine to drill holes with a depth ≥120mm and insert suitable rock anchors.

[0027] Subsequently, the fixing frame 1 is placed stably on the installation foundation. The fixing frame 1 is positioned using pre-set connecting lugs on both sides of its bottom, which are integrally formed with the fixing frame 1 and have a thickness ≥8mm. The connecting lugs have through holes adapted to expansion bolts / rock anchors. Bolts are passed through these through holes and screwed into the pre-set holes in the foundation. The bolts are tightened with a torque wrench, with the torque controlled at 50-80 N·m, ensuring a tight fit between the fixing frame 1 and the foundation. During installation, the level of the fixing frame 1 must be calibrated with a level instrument, with a horizontal error ≤0.5°. If tilting occurs, a thin steel sheet (0.5-2mm thick) can be placed between the connecting lugs and the foundation for adjustment, ensuring the overall stability of the fixing frame 1. For long-distance pipeline support, multiple fixing frames 1 can be bolted together using the assembly blocks 12 on both sides of the fixing frame 1 and the assembly holes. The spacing between adjacent fixing frames 1 is determined according to the pipeline diameter, typically 1.5-3m, forming a continuous support structure.

[0028] Next, pulling the blocking block 10 causes the actuating block to move outward along the actuating groove of the protective ring 6. The internal gear 8, pulled by the actuating block, compresses the spring 9 and separates from the first gear 7 on the actuating rod 35, releasing the restriction on the rotation of the lead screw 34. At this time, hold the knob 5 with anti-slip texture on the outer wall and turn it clockwise or counterclockwise. The knob 5 drives the lead screw 34 to rotate around the connecting ring. Because the lead screw 34 is threaded into the threaded hole 33 of the drive tube 32, and the drive tube 32 is limited by the fixed groove 31 and cannot rotate, the rotation of the lead screw 34 will be converted into the linear sliding of the drive tube 32 along the fixed groove 31. When the lead screw 34 is rotated clockwise, the drive tube 32 moves closer to the connecting ring, and when rotated counterclockwise, it moves away from the connecting ring. During the sliding process of the drive pipe 32, the hinge rod 36 hinged to its outer wall will simultaneously push or pull the adjusting plate 2, causing the adjusting plate 2 to rotate around the pivot of the inner wall of the fixed frame 1. Depending on the inner diameter of the pipe to be supported, such as DN500-DN1500, and the laying slope, 0°-30°, observe the fit between the adjusting plate 2 and the outer wall of the pipe. When the auxiliary frame 11 of the adjusting plate 2 and the inner wall of the rotating connecting roller are completely in contact with the bottom of the pipe, stop rotating the knob 5; release the blocking block 10, and the spring 9 will reset after losing external force constraint, pushing the internal gear 8 to move towards the first gear 7 and re-meshing, locking the screw 34 to prevent the adjusting plate 2 from shifting angle due to pipe pressure or vibration. At the same time, the blocking block 10 is tightly fitted to the outer wall of the protective ring 6 through the sealing gasket on one side, sealing the actuation groove and preventing rainwater, mud or pipe installation debris from entering the interior of the protective ring 6, and preventing the gear and screw 34 from rusting and jamming.

[0029] Finally, the pipe is slowly placed on the auxiliary frame 11 of the adjusting plate 2: the rollers on the inner side of the auxiliary frame 11 can convert the sliding friction between the pipe and the support surface into rolling friction, which can greatly reduce the resistance when pushing the pipe, making it easier to adjust the pipe to the preset laying position, such as the flange interface; the baffle plate 4 on the inner side wall of the fixing groove 31 in the fixing frame 1 always abuts against the top of the drive pipe 32, which can cover the exposed threaded rod 34 in the fixing groove 31, preventing concrete debris, sand and gravel generated during pipe installation from adhering to the thread of the threaded rod 34, and ensuring the smooth rotation of the threaded rod 34 during subsequent adjustment.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
