Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a pipe mounting bracket for water conservancy projects. Background Technology

[0002] In pipeline construction for water conservancy projects and municipal water supply and drainage, it is often necessary to connect and install single long pipelines to form a pipe network. Currently, after the pipeline is lowered into the trench or placed on the support, its position adjustment mainly relies on two methods: one is to use simple triangular supports or sleepers for initial support, and then use tools such as pry bars and manual hoists for rough adjustment by hand. This method is inefficient, has poor adjustment accuracy, and poses safety hazards; the other is to use hoisting equipment for suspension adjustment. Although it has great power, the equipment is bulky and costly, and it is inconvenient to operate when making fine adjustments to the horizontal angle of the pipeline, lacking flexibility. Therefore, there is a need for a pipeline installation auxiliary equipment that can provide stable support, achieve flexible adjustment with multiple degrees of freedom, and has a buffer protection function. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a pipe mounting bracket for water conservancy projects, which solves the technical problems of inflexible adjustment and difficulty in quickly adapting to different pipe diameters in existing pipe installation methods.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides a pipe installation frame for water conservancy projects, including a base, a column vertically fixed on the base, a support adjustment unit movably mounted on the upper end of the column, and a pipe clamping unit mounted on the support adjustment unit for clamping pipes. The support adjustment unit includes a sliding column slidably connected to the column, a transmission box fixedly mounted on the top of the sliding column, a support seat mounted above the transmission box via a shock-absorbing component, and an adjustment component mounted inside the transmission box for driving the support seat to rotate horizontally. The pipe clamping unit includes an installation groove mounted along the length of the upper wall of the support seat, a pull rod rotatably mounted in the installation groove, a pair of sliders slidably mounted in the installation groove and threadedly connected to the pull rod, and a gripper assembly mounted on each slider. The adjustment component drives the support seat to rotate, adjusting the horizontal angle of the pipe. Rotating the pull rod drives the pair of sliders to move towards or away from each other, adjusting the spacing of the gripper assemblies to accommodate different pipe diameters.

[0005] The pipe installation bracket for water conservancy projects proposed in this invention involves fixing the device to the installation position via a base, operating the lifting assembly to raise and lower the sliding column and the entire upper mechanism to a suitable height, placing the pipe to be installed between a pair of clamping jaw assemblies, rotating the pull rod to drive the two sliders to move towards each other, so that the clamping jaw assemblies initially grip the pipe from both sides, and adjusting the support base to rotate horizontally by the adjusting assembly to adjust the horizontal orientation of the pipe so that its port is aligned with the port of the pipe to be connected, and locking the clamping jaw assemblies to firmly fix the pipe, then welding or flange connection operations can be performed. The shock absorption assembly can effectively absorb the impact and vibration generated during the placement or adjustment of the pipe.

[0006] Optionally, a lifting assembly for driving the sliding column to rise and fall is provided between the column and the sliding column.

[0007] The lifting assembly allows for adjustment of the mounting bracket support height, enabling operators to position the pipeline to the required elevation based on the trench depth or docking point height. This eliminates the cumbersome procedures of raising or deepening the trench, greatly improving construction adaptability.

[0008] Optionally, the lifting assembly includes a first screw rotatably mounted inside the bottom of the column, a screw hole threaded into the slide column and threadedly engaged with the first screw, a rotating rod rotatably mounted horizontally at the bottom of the column, a main gear fixedly mounted at one end of the rotating rod, and a secondary gear fixedly fitted onto the bottom of the first screw and meshing with the main gear; a pair of guide grooves are provided on the inner walls of both sides of the column, and a pair of guide blocks are fixedly mounted on the outer walls of both sides of the slide column and slidably connected to the guide grooves; rotating the rotating rod can drive the first screw to rotate through gear transmission, thereby driving the slide column to rise and fall.

[0009] The gear and screw transmission mechanism converts the horizontal rotary input into a vertical linear lifting output. The cooperation between the guide block and the guide groove ensures that the lifting process of the slide column is smooth and without shaking, thus guaranteeing the stability of the pipeline support at high altitudes and preventing misalignment due to sway.

[0010] Optionally, the other end of the lever extends to the outside of the column and is fixedly fitted with a handwheel.

[0011] The handwheel provides the operator with a convenient point of force application, improving the ease of operation.

[0012] Optionally, the adjustment assembly includes a worm gear rotatably mounted in the transmission box, a main shaft rotatably mounted longitudinally in the transmission box, a worm wheel fixedly mounted on the main shaft, and a handwheel fixedly disposed at one end of the worm gear and extending to the outside of the transmission box; the worm wheel meshes with the worm gear, and rotating the handwheel can drive the worm wheel and the main shaft to rotate through the worm gear.

[0013] The worm gear drive is used as the horizontal angle adjustment mechanism, which has a self-locking characteristic. After the pipe angle is adjusted, the worm can effectively lock the worm wheel to prevent the pipe from rotating spontaneously under external interference, thus ensuring the stable maintenance of the docking angle.

[0014] Optionally, the damping assembly includes a damping seat fixedly mounted on the upper end of the spindle, and a plurality of spring dampers evenly distributed between the damping seat and the support seat.

[0015] When the pipeline is subjected to an accidental impact, the impact force is transmitted to the spring shock absorber through the support seat. The compression and rebound of the spring can absorb and dissipate most of the impact energy, preventing the rigid impact from being directly transmitted to the transmission box, column and base, thus protecting the pipeline and support structure itself.

[0016] Optionally, the lower wall of the shock absorber is provided with an annular rail, and the upper wall of the transmission box is provided with an annular groove that slides with the annular rail.

[0017] The engagement of the annular rail and the annular groove forms a bearing plane, allowing the support base and the pipe clamping unit above it to rotate smoothly horizontally above the shock absorber base, while bearing vertical loads, ensuring the flexibility of rotation adjustment and the reliability of the overall structure.

[0018] Optionally, the gripper assembly includes a clamping plate fixedly disposed on the upper wall of the slider, an adjustment groove opened vertically in the clamping plate, a second screw rotatably installed in the adjustment groove, a movable block slidably disposed in the adjustment groove and threadedly connected to the second screw, and a positioning pressure plate fixedly disposed on the side wall of the movable block; rotating the second screw can drive the positioning pressure plate to rise and fall, so as to press or release the pipe from above.

[0019] By rotating the second screw to drive the positioning pressure plate to move up and down, a vertical clamping force is applied from above the pipe. Combined with the clamps that hold the pipe from both sides, a multi-point constraint is formed on the pipe, which is firmly and reliably fixed and can effectively prevent the pipe from rolling or moving axially during installation.

[0020] Optionally, the lower wall of the positioning plate is provided with a beveled structure for contacting the outer wall of the pipe.

[0021] The beveled structure increases the contact area during clamping, reduces local pressure, and avoids damage to the pipe's anti-corrosion layer. At the same time, the bevel helps to distribute the clamping force more evenly.

[0022] Optionally, the base is provided with mounting holes for fixing the entire device to the foundation or platform.

[0023] The mounting holes allow for the secure anchoring of the entire pipe mounting bracket to the concrete foundation or construction platform using anchor bolts or expansion bolts, providing a solid foundation for the support and adjustment of heavy-duty pipelines and preventing the equipment from tipping over or shifting during operation.

[0024] (III) Beneficial Effects The beneficial effects of this invention are: Through integrated design, the height adjustment, horizontal angle adjustment, pipe diameter clamping and impact buffering functions required for pipe installation are effectively integrated. Among them, the lifting component composed of gears and screws not only realizes stepless adjustment of pipe height, but its guide structure also ensures no swaying during the lifting process; the horizontal adjustment component using worm gear transmission provides angle adjustment while maintaining the adjusted pipe orientation with its self-locking characteristics, preventing accidental deflection caused by external forces. The clamping unit, consisting of a pull rod, an adjustable slider, and a gripper assembly with a beveled pressure plate, can quickly adapt to different pipe diameters and achieve a firm lock on the pipe through multi-point constraint, effectively preventing displacement during construction. The shock-absorbing rotation mechanism, composed of spring shock absorbers and annular track groove structure, effectively absorbs and isolates pipeline impact vibrations to protect the pipe openings and equipment itself, while ensuring smooth horizontal rotation and stable load bearing of the support base. This device significantly reduces the reliance on hoisting equipment for fine-tuning, transforming the traditional multi-person, extensive adjustment process into one-person operation, greatly improving the accuracy of pipeline connection, work efficiency, and safety of the construction process.

Detailed Implementation

[0028] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The pipe installation frame for water conservancy projects proposed in this invention provides a specialized device for multi-dimensional adjustment of pipe installation through integrated lifting, rotating, clamping and buffering mechanisms. It achieves labor-saving lifting using gear and screw transmission, achieves self-locking angle fine adjustment through worm gear, achieves adaptive clamping of pipe diameter with the help of pull rod and adjustable pressure plate, and reduces impact by combining shock absorption components. It effectively solves the problems of difficult adjustment, insufficient accuracy and unstable fixation in traditional installation methods.

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0031] Please see Figure 1-3 This invention provides a technical solution: a pipe installation frame for water conservancy projects. Its base 1 is a thick rectangular steel plate with multiple mounting holes 25 drilled in it. A hollow column 2 with a square cross-section is vertically welded and fixed to the center of the base 1. A vertical first screw 8 is installed at the bottom of the column 2 via a bearing seat. A rotating rod 9 is horizontally installed on the lower outer side of the column 2, supported by a bearing seat. One end of the rotating rod 9 is fixed with a main gear 10, which meshes with the secondary gear 11 at the bottom of the first screw 8. A handwheel is installed at the other end of the rotating rod 9. A sliding column 3 is fitted inside the column 2, with a threaded hole inside that mates with the first screw 8. Guide blocks 13 on both sides slide in contact with vertical guide grooves 12 on the inner wall of the column 2. A transmission box 4 is fixed to the top of the sliding column 3. Inside the transmission box 4, a main shaft... The bearing is installed vertically, and a worm gear 15 is fixed on the main shaft. A worm 14 is installed horizontally and meshes with the worm gear 15. One end of the worm 14 extends out of the housing and is equipped with a handwheel. A shock absorber 16 is fixed at the top of the main shaft. The annular guide rail on its lower surface slides in cooperation with the annular groove 19 on the upper surface of the transmission box 4. Multiple spring shock absorbers 17 are evenly connected between the shock absorber 16 and the rectangular support 5 above. The top surface of the support 5 has a T-shaped mounting groove. A pull rod 6 is installed in it through the bearing seat, and one end is equipped with a handwheel. Two T-shaped sliders 7 are embedded in the groove and cooperate with the pull rod. A vertical clamping plate 20 is fixed on each slider 7. A vertical adjustment groove 21 is opened on the clamping plate 20. A moving block 23 with an inclined positioning pressure plate 24 is driven in the groove by a second screw 22. A handwheel is installed at the upper end of the second screw 22.

[0032] The working process of this device is as follows: During operation, firstly, the entire mounting frame is firmly fixed in the working position through the mounting holes 25 on the base 1. Then, according to the pipeline design installation height, the handwheel on the column 2 is rotated, and the first screw 8 is driven to rotate through the main and auxiliary gears 11, thereby driving the sliding column 3, the transmission box 4 and all the components above to rise and fall smoothly along the guide groove 12 for preliminary height positioning.

[0033] Subsequently, according to the construction requirements, the orientation angle of the pipeline is adjusted. The handwheel of the worm gear 14 on the transmission box 4 is turned, and the main shaft is driven to rotate through the worm wheel 15 and the worm gear 14 pair. The main shaft drives the support seat 5 to rotate smoothly in the horizontal plane through the shock absorber 16 and the spring shock absorber 17, and stops after rotating to the specified angle.

[0034] Subsequently, the pipe is horizontally hoisted onto the support base 5 using hoisting equipment, positioning it between the two clamping plates 20. The handwheel of the pull screw 6 is rotated to drive the two T-shaped sliders 7 to slide towards each other along the mounting groove, causing the clamping plates 20 on both sides to approach and contact the pipe wall from the radial sides of the pipe. Then, the handwheels of the second screws 22 on the two clamping plates 20 are rotated respectively to drive the moving block 23 to lower the positioning pressure plate 24. The inclined structure of the plate adapts to the pipe diameter and presses the pipe from above, forming a stable clamp. After clamping is completed, the shock absorption component can absorb the slight vibration of the pipe caused by its own force or external force, while the groove of the annular rail 18 ensures smooth rotation and stable load bearing.

[0035] After confirming that all positions are correct, subsequent installation work such as welding or flange connection can be carried out while the pipeline is reliably positioned and clamped.
