Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically a transportation auxiliary device for prefabricated pipelines and matching flanges. Background Technology

[0002] In the fabrication of prefabricated computer rooms, pipes and flanges are critical connecting components, and their transportation quality directly affects the efficiency of the project installation. Currently, the protection of pipe components during long-distance transportation suffers from the following technical deficiencies: 1. Deformation caused by instability of fixed structure: Traditional transportation often uses rope binding combined with wooden blocks for fixation, which lacks axial restraint. When the vehicle bumps, the pipeline is prone to lateral displacement, causing collision and wear of the flange sealing surface. At the same time, the pipe body is prone to elliptic distortion due to radial stress concentration, which seriously affects the pressure bearing performance and connection accuracy.

[0003] 2. Resonance damage under dynamic load: Existing fixing frames mostly adopt rigid buckle designs, which cannot effectively attenuate low-frequency vibration energy during transportation.

[0004] 3. Conflict between space utilization and protection: To increase the volume of a single transport, the industry generally adopts multi-layer pipe stacking solutions. However, the existing V-shaped support spacing is fixed and relatively long, making it difficult to adapt to different pipe diameter requirements, and there is a lack of anti-slip structure between layers.

[0005] 4. Lack of flange edge protection: In current transportation, the flange part is mostly exposed. When encountering sudden braking or turning, the flange is easily scratched by friction with the strapping.

[0006] Therefore, there is an urgent need for an auxiliary device that can stably transport prefabricated pipes and their flanges. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides the following technical solution: a transportation auxiliary device for prefabricated pipes and matching flanges, comprising a pipe body and a flange, wherein the flange is fixedly installed at the end of the pipe body, and also includes an H-shaped support steel frame, wherein the transverse length and longitudinal length of the support steel frame are consistent, and the entire frame is hollow. Fixing blocks are fixedly screwed to both sides of the support steel frame, and a slide rail is fixedly installed on the top of the fixing block. An arc-shaped limiting component is slidably connected inside the slide rail, and a triangular limiting component is provided between two adjacent pipe bodies to further limit the pipe movement.

[0008] As an optimization, the arc-shaped limiting component includes an arc-shaped movable block, and a sliding seat is fixedly installed on the bottom side of the movable block. The sliding seat is slidably connected inside the slide rail, and the sliding seat is made of stainless steel cold-rolled plate.

[0009] As an optimization, a protective pad is glued to the top arc surface of the movable block, and the protective pad is made of silicone material and is arc-shaped and tightly attached to the outer wall of the pipe body.

[0010] As an optimization, the cross-section of the triangular limiting component is triangular, the main body is made of hard plastic rubber, the hypotenuse is curved, and it is made of a flexible plastic material. The triangular limiting component adopts a mortise and tenon structure design that can be interlocked and limited.

[0011] As an optimization, a limiting groove is provided on one side of the triangular limiting member, and a limiting protrusion is fixedly installed on the other side of the triangular limiting member, with the limiting protrusion correspondingly engaging inside the limiting groove.

[0012] As an optimization, it also includes a protective cover that is fitted over the outside of the flange to protect it, and the protective cover adopts a hollow design.

[0013] As an optimization, it also includes an anti-resonance wedge block assembly, which includes several sets of wedge blocks one and wedge blocks two, and the wedge blocks one and wedge blocks two are interlocked with each other by tenon and mortise. The bottom of the lowest wedge block one is fixedly installed with a sliding seat two, and the sliding seat two is slidably connected to the inside of the slide rail. The inside of the wedge block one is provided with a groove. The side of the wedge block two is fixedly installed with a locking rod, and the locking rod is inserted into the groove. The top side of the wedge block two is provided with a groove. The bottom side of the wedge block one is fixedly installed with a plug rod, and the plug rod is inserted into the groove.

[0014] As an optimization, the supporting steel frame is made of Q345B low alloy structural steel, and the surface is subjected to micro-arc oxidation treatment, and the slide rail contact surface is sprayed with tungsten carbide coating.

[0015] The beneficial effects of this utility model are: The transportation auxiliary device for this prefabricated pipeline and its matching flanges, through the dynamic combination structure of H-shaped support steel frame and slide rail with double arc-shaped limiting components, can achieve axial spacing adjustment. Combined with the friction layer of the self-adhesive arc-shaped silicone surface on the inner wall of the movable block and the coordinated fixation of the triangular limiting components, it breaks through the traditional fixed support spacing limitation, thereby improving the applicability of pipeline specifications for single transportation and enhancing practicality.

[0016] The transport auxiliary device for this prefabricated pipe and its matching flange suppresses the lateral displacement of the pipe by using the tilt angle designed to match the cross-sectional modulus of the limiting wedges with that of the H-beam. In conjunction with the radial wrapping of the pipe by the limiting device, it reduces the fluctuation of the pipe's friction coefficient when the vehicle is bumpy, controls the amount of lateral displacement, and then locks the pipe gap by the engagement of the anti-resonance wedge group, attenuating the low-frequency vibration energy during transportation and avoiding stress concentration caused by rigid clamping.

[0017] The transport auxiliary device for this prefabricated pipeline and its matching flanges, by adopting the shape of an arc-shaped protective cover, can fit and protect the flanges, thereby preventing pipelines from colliding with each other, reducing material consumption, and providing better protection.

[0018] The transport auxiliary device for this prefabricated pipe and its matching flange, through the longitudinal adjustability of the H-shaped steel rail slide and the vertical support design of the wedge block, achieves anti-slip fixation when stacking multiple layers of pipes, solving the problems of fixed spacing and upward shift of the center of gravity of traditional V-shaped supports, and increasing the stacking height to more layers without reducing stability.

[0021] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] 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.

[0023] Please see Figure 1-2 A transport auxiliary device for prefabricated pipes and matching flanges includes a pipe body 1 and a flange 2. The flange 2 is fixedly installed at the end of the pipe body 1. It also includes an H-shaped support steel frame 3. The support steel frame 3 is made of Q345B low alloy structural steel and the surface is micro-arc anodized. The contact surface of the slide rail 5 is sprayed with tungsten carbide coating. The transverse length and longitudinal length of the support steel frame 3 are the same. It is all hollow. Fixing blocks 4 are fixedly screwed to both sides of the support steel frame 3. The top of the fixing blocks 4 is fixedly installed with the slide rail 5. The slide rail 5 is slidably connected with an arc-shaped limiting piece 6. A triangular limiting piece 7 is set between two adjacent pipe bodies 1 to further limit the pipe. The arc-shaped limiting piece 6 can fit different pipe sizes well, increase transport efficiency, and play a better protective role. The triangular limiting piece 7 further fixes the pipe to prevent lateral movement of the pipe and avoid friction damage caused by left and right swaying. At the same time, it can also play a supporting role to prevent the pipe from deforming due to vertical stacking. Please see Figure 3 The arc-shaped limiting component 6 includes an arc-shaped movable block 8, and a sliding seat 9 is fixedly installed on the bottom side of the movable block 8. The sliding seat 9 is slidably connected inside the slide rail 5. The sliding seat 9 is made of stainless steel cold-rolled plate. A protective pad is glued to the top arc surface of the movable block 8. The protective pad is made of silicone and is arc-shaped and tightly attached to the outer wall of the pipe body 1. It can fit different pipe sizes well, increase transportation efficiency, and play a better protective role.

[0024] Please see Figure 4 The triangular limiting component 7 has a triangular cross-section, and the main body is made of hard plastic rubber. The hypotenuse is curved and made of flexible plastic. The triangular limiting component 7 adopts a mortise and tenon structure design to interlock and limit the position. A limiting groove 12 is opened on one side of the triangular limiting component 7, and a limiting protrusion 13 is fixedly installed on the other side of the triangular limiting component 7. The limiting protrusion 13 is correspondingly engaged in the limiting groove 12. By clamping two sets of limiting wedges 11 between the two pipes and making the limiting protrusion 13 engage in the limiting groove 12, shock absorption and further reinforcement can be achieved, preventing the pipe from moving laterally during transportation and avoiding friction damage caused by left and right swaying. At the same time, it plays a supporting role and prevents the pipe from deforming due to vertical stacking. Please see Figure 5 It also includes a protective cover 14 that is fitted over the outside of the flange 2 to protect it. The protective cover 14 has a hollow design and is fixed by screws passing through the bolt holes of the flange 2. The protective cover 14 is fitted over the outside of the flange 2 to reduce the risk of damage and to prevent deformation and various contaminations during transportation.

[0025] Please see Figure 6 It also includes an anti-resonance wedge assembly, which comprises several sets of wedges 15 and 17, with wedges 15 and 17 interlocked by tenons and mortise joints. A sliding seat 2 16 is fixedly installed at the bottom of the lowest wedge 15, and the sliding seat 2 16 is slidably connected inside the slide rail 5. A groove is provided inside the wedge 15. A locking rod 18 is fixedly installed on one side of the wedge 17 corresponding to the wedge 17 position, and the locking rod 18 is inserted into the groove. The top of the wedge 17... A groove 19 is provided on the side. A rod 20 is fixedly installed on the bottom side of the wedge 15 corresponding to the groove 19, and the rod 20 is inserted into the groove 19. By inserting the locking rod 18 into the locking slot, the wedge 2 17 can be assembled on the top of the wedge 15. Then, the rod 20 is inserted into the groove 19, and the assembly can be carried out in sequence. Then, push it close to the outside of the pipe, lock the gap of the pipe through the interlocking, attenuate the low frequency vibration energy during transportation, and avoid stress concentration caused by rigid clamping.

[0026] In use, first slide the two sets of arc-shaped limiting pieces 6 closer together so that the movable blocks 8 on both sides correspond to the outer diameter of the pipe, which facilitates the placement and limiting of the pipe. Then, place a limiting wedge 11 between the two pipes, and then insert another limiting wedge 11 and press it down so that the two sets of limiting protrusions 13 are stuck between the adjacent pipes. The limiting protrusions 13 will be stuck in the limiting groove 12 for positioning, which can further fix the pipe and prevent the pipe from moving laterally. At the same time, slide the second sliding seat 16 so that the anti-resonance wedge group abuts against the outside of the pipe for further fixation and restriction. By locking the pipe gap through biting, the low-frequency vibration energy during transportation is attenuated, and stress concentration caused by rigid clamping is avoided.

[0027] At the same time, the protective cover 14 is then placed on the outside of the flange 2 and fixed by screws through the bolt holes of the flange 2. This will fix the flange 2 to reduce the risk of damage and prevent it from deforming and becoming contaminated during transportation.

[0028] In summary, the transportation auxiliary device for this prefabricated pipeline and its matching flange, through the dynamic combination structure of the H-shaped support steel frame 3, the slide rail 5, and the double arc-shaped limiting component 6, can achieve axial spacing adjustment. Furthermore, combined with the friction layer 10 of the silicone self-adhesive arc-shaped surface on the inner wall of the movable block 8 and the coordinated fixation of the triangular limiting component 7, it breaks through the traditional limitations of fixed support spacing, thereby improving the applicability of pipeline specifications for single transportation and enhancing practicality.

[0029] The lateral displacement of the pipeline is suppressed by the tilt angle designed to match the cross-sectional modulus of the H-beam by the limiting wedge 11. Combined with the radial wrapping of the pipeline by the limiting device, the fluctuation of the pipeline's friction coefficient during vehicle bumps is reduced, and the amount of lateral displacement is controlled. Then, the pipeline gap is locked by the engagement of the anti-resonance wedge group, which attenuates the low-frequency vibration energy during transportation and avoids stress concentration caused by rigid clamping.

[0030] By adopting the shape of the arc-shaped protective cover 14, the flange 2 can be fitted and protected, thereby avoiding collisions between pipes, reducing material consumption and providing better protection.

[0031] By utilizing the longitudinal adjustability of the H-shaped steel rail slide rail 5 and the vertical support design of the wedge block, anti-slip fixation is achieved when stacking multiple layers of pipes, solving the problems of fixed spacing and upward shift of the center of gravity in traditional V-shaped brackets, and enabling the stacking height to be increased to more layers without reducing stability.
