Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for the construction of prefabricated electric conduit pipes, specifically a prefabricated integrated high and low voltage electric conduit pipe connection construction scaffold. Background Technology

[0002] Precast cable ducts are widely used in power engineering construction due to their advantages of regular structure, convenient laying, and ability to separate high-voltage and low-voltage cables. During the construction of cable ducts, multiple sections of precast cable ducts need to be connected and assembled to form a complete cable laying channel. During the connection construction, scaffolding is required to lift, transport, position, and adjust the cable ducts.

[0003] The existing scaffolding for connecting electric conduit has several drawbacks: First, the positioning and movement functions cannot be switched smoothly, causing the electric conduit to sway and become unstable during hoisting and transportation. During connection and adjustment, the movement is subject to high resistance and is prone to jamming, affecting construction safety and convenience. Second, uneven force distribution during electric conduit positioning can easily lead to localized damage. Furthermore, the lack of a stable limiting structure after scaffolding installation makes it prone to displacement when the electric conduit is moved, affecting connection accuracy. Third, the assembly and connection between the scaffolding and the electric conduit is cumbersome, resulting in uneven overall force distribution during hoisting and transportation. It also has poor compatibility with different specifications of electric conduit, requiring additional accessories for different specifications, increasing construction costs and procedural complexity.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 5 This embodiment discloses a prefabricated high and low voltage integrated cable tray connection construction scaffold. The cable tray 1 used for connection is a prefabricated high and low voltage integrated structure with multiple sets of circular slots inside. These slots are used for the insertion and arrangement of high and low voltage cables and communication and network pipelines. Physical separation is achieved through built-in PC pipes, which realizes the separate laying of high and low voltage cables, avoids mutual interference and electromagnetic interference, reduces the risk of short circuits, and improves the safety and standardization of cable laying. These circular slots 4 adopt a standard two-layer, three-row compact layout design, which efficiently utilizes the internal... The space is designed to accommodate the pre-embedded needs of multi-circuit pipelines and meet the requirements of future power capacity expansion scenarios. One end of the electric conduit 1 is integrally formed with a connector 5, and the other end is provided with a corresponding docking groove 2. The shape and size of the connector 5 are compatible with the shape and size of the docking groove 2, and the docking structure has good sealing performance, meeting the waterproof and dustproof standards. This allows the connector 5 of one set of electric conduits 1 to be accurately inserted into the docking groove 2 of another set of electric conduits 1. The circular holes and grooves of the two sets of electric conduits 1 are connected to each other, ensuring that various pipelines can be smoothly passed through after docking, while preventing groundwater from seeping into and soaking the pipelines. Four sets of through grooves 3 are symmetrically distributed on both sides of the electric cable manifold 1. The suspension components pass through these grooves 3, ensuring smooth traction without affecting the structural strength of the electric cable manifold 1. Two sets of symmetrically distributed sliding grooves 7 are provided at the bottom of the electric cable manifold 1. The spacing between the two sets of sliding grooves 7 matches the spacing between the two frame bodies 6. The two frame bodies 6 are inserted into the two sets of sliding grooves 7 respectively, achieving precise assembly between the frame bodies 6 and the electric cable manifold 1. After docking, the electric cable manifold can be networked with prefabricated functional manifolds such as straight manifolds, corner manifolds, tee manifolds, and four-way manifolds, and form a complete underground pipeline transmission system with prefabricated cable trenches, meeting the application needs of pipeline turning, branching, and maintenance in all scenarios.

[0026] The docking construction scaffold that is compatible with the electric conduit 1 includes two parallel frame bodies 6. The two frame bodies 6 are fixedly connected by multiple sets of connecting plates 10 to form a stable frame structure. The connecting plates 10 are evenly spaced along the length of the frame body 6 to ensure that the two frame bodies 6 are tightly connected and evenly stressed, so as to avoid deformation or misalignment of the frame body 6 during construction.

[0027] The frame 6 integrates a rolling drag reduction component, a lifting and holding positioning component, and a suspension component. The rolling drag reduction component is fixed on the upper surface of the frame 6 and is used to reduce the moving friction resistance between the electric pipe 1 and the frame 6. The frame 6 is fitted to the bottom of the electric pipe 1 and forms a precise fit with the sliding groove 7 at the bottom of the electric pipe 1, providing a support foundation for the docking, movement, and positioning of the electric pipe 1. The frame 6 has an internal cavity, which serves as the lifting and holding positioning component's lifting space. This allows the lifting and holding positioning component to move up and down within the cavity, thereby raising or lowering it to a position higher or lower than the rolling drag reduction component and forming a preset height difference with the working surface of the rolling drag reduction component. This preset height difference can be preset according to the specifications of the electric pipe 1 and construction requirements. The core purpose is to ensure that the rolling drag reduction component and the lifting and holding positioning component do not simultaneously contact the inner wall of the sliding groove 7 at the bottom of the electric pipe 1, avoiding mutual interference and affecting the function switching.

[0028] One end of the suspension component is fixedly connected to the lifting and holding positioning component, and the other end is used to connect to external lifting equipment. Through the traction driving force of the lifting equipment, the lifting and holding positioning component is driven to move up and down along the cavity inside the frame 6, realizing the function switching between positioning and movement. During the hoisting and transportation of the electric pipe 1, the lifting and holding positioning component abuts against the electric pipe 1 to realize the relative positioning of the electric pipe 1 and the work frame, preventing the electric pipe 1 from shaking or shifting during hoisting, ensuring that the electric pipe 1 is suspended synchronously with the work frame, and improving the safety and stability of hoisting and transportation. When the entire work frame is lowered to the installation position of the cable trench, the holding and positioning state of the lifting and holding positioning component is released. Under the action of external force (such as manual pushing or mechanical traction), the electric pipe 1 can move laterally along the frame 6 with the help of the drag reduction effect of the rolling drag reduction component, thereby adjusting the docking position of the electric pipe 1 and realizing the precise docking operation of multiple sets of electric pipe 1.

[0029] The rolling friction reduction component is a roller 11. Multiple sets of rolling grooves 19 are opened on the upper surface of the frame 6. The multiple sets of rolling grooves 19 are evenly spaced along the length of the frame 6. A roller 11 is rotatably installed in each set of rolling grooves 19 through a rotating shaft. The roller 11 can rotate freely around the rotating shaft. The rolling friction of the roller 11 replaces the sliding friction, effectively reducing the frictional resistance when the electric pipe 1 moves laterally, making the docking and adjustment of the electric pipe 1 smoother, reducing the labor intensity of construction personnel, and at the same time avoiding wear on the inner wall of the sliding groove 7 at the bottom of the electric pipe 1 due to sliding friction.

[0030] The lifting and positioning assembly includes a horizontal plate 17, multiple support plates 14, and anti-slip strips 15. The cavity inside the frame 6 is a mounting cavity 16, which extends through the length of the frame 6. The horizontal plate 17 is horizontally positioned within the mounting cavity 16 and can move smoothly up and down along the inner wall of the mounting cavity 16. The dimensions of the horizontal plate 17 are matched with the dimensions of the mounting cavity 16 to ensure that the horizontal plate 17 moves without jamming or shifting during lifting. Multiple support plates 14 are fixed at intervals along the length of the horizontal plate 17 on its upper surface and are symmetrically distributed along each lifting block 13 to ensure uniform support force on the support plates 14. Multiple sets of first lifting grooves are correspondingly formed on the upper surface of the frame 6. 18. Multiple sets of first lifting grooves 18 correspond one-to-one with multiple top holding plates 14. The top end of the top holding plate 14 is inserted into the corresponding first lifting groove 18 and can move up and down along the first lifting groove 18. The first lifting groove 18 plays a guiding and limiting role for the top holding plate 14 to prevent the top holding plate 14 from tilting during the lifting process. Each top holding plate 14 has an anti-slip strip 15 fixed to its top end. The anti-slip strip 15 is made of rubber or anti-slip plastic material and has anti-slip texture on its surface, which can increase the friction with the inner wall of the slide groove 7 of the electric pipe 1 and improve the stability of the top holding positioning. The top height of the roller 11 is higher than the top height of the anti-slip strip 15 to ensure that the roller 11 is in contact with the inner wall of the slide groove 7 under normal conditions.

[0031] Multiple top support plates 14 and multiple sets of rollers 11 are staggered together. That is, along the length of the frame 6, top support plates 14 are set between two adjacent rollers 11 (the number does not need to correspond one-to-one). When the electric tube 1 moves, the rollers 11 can provide support and reduce resistance evenly for the electric tube 1. When the electric tube 1 is positioned, the multiple top support plates 14 can support the electric tube 1 evenly, ensuring that the electric tube 1 is subjected to uniform force and avoiding excessive local force that may cause damage to the electric tube 1 or unstable positioning.

[0032] The suspension assembly includes a lifting block 13, a connecting rope 9, and a second hook 8. The lifting block 13 is fixed to the upper surface of the horizontal plate 17 and rises and falls synchronously with the horizontal plate 17. A second lifting groove 20 is correspondingly provided on the upper surface of the frame 6. The lifting block 13 is inserted into the second lifting groove 20 and can move up and down along the second lifting groove 20. The second lifting groove 20 and the first lifting groove 18 are independent of each other to avoid interference between them. One end of the connecting rope 9 is fixedly connected to the top of the lifting block 13. The connection method can be bolt fixing or binding fixing to ensure a firm connection. The other end of the connecting rope 9 is fixedly connected to the second hook 8. The connecting rope 9 is inserted entirely into the through groove 3 of the electric conduit 1. The through groove 3 provides space for the movement of the connecting rope 9 and does not interfere with the traction action of the connecting rope 9.

[0033] The second hook 8 is set into four groups, and the four groups of second hooks 8 correspond to the lifting blocks 13 on the two frames 6 respectively. When in use, the four groups of second hooks 8 need to be simultaneously hooked onto the same lifting equipment to ensure that the lifting blocks 13 on the two frames 6 are subjected to force and lifted and lowered synchronously when the lifting equipment is pulling, so as to avoid the horizontal plate 17 from tilting, which would cause the lifting top holding positioning component to fail. At the same time, it ensures that the frame and the electric conduit 1 are subjected to uniform force during the hoisting process, thereby improving the hoisting safety.

[0034] Multiple sets of tapered plug-in rods 12 are fixed to the bottom of both frame bodies 6. The tapered plug-in rods 12 are evenly spaced along the length of the frame body 6. The tapered plug-in rods 12 are set vertically downward, with their top ends fixedly connected to the bottom of the frame body 6. The bottom ends are tapered to facilitate insertion into the soil in the cable trench. When the frame is lowered to the installation position, the tapered plug-in rods 12 are inserted into the soil in the cable trench to fix and limit the frame body 6, preventing the frame body 6 from shifting when the cable tube 1 moves laterally, and ensuring the accurate docking position of the cable tube 1.

[0035] The thickness of the frame 6 is greater than the thickness of the groove 7 of the cable conduit 1. When the frame 6 is inserted into the groove 7, the end of the frame 6 is exposed outside the groove 7. The exposed part can fully contact the bottom surface of the cable trench, providing stable support for the frame 6.

[0036] The working process of this embodiment:

[0037] 1. Assembly and hoisting alignment of the electric conduit: First, hoist the electric conduit 1 using the hoisting equipment, move the electric conduit 1 to a position near the top of the work stand and pause. Then, thread the connecting rope 9 of the suspension component through the through groove 3 on the surface of the electric conduit 1 and attach the second hook 8 to the hoisting equipment. After attachment, continue to move the work stand to adjust its position so that the two frame bodies 6 of the work stand are precisely aligned with the two sets of sliding grooves 7 at the bottom of the electric conduit 1. After alignment, slowly lower the electric conduit 1 and insert the frame bodies 6 into the corresponding sliding grooves 7 to complete the assembly of the electric conduit 1 and the work stand.

[0038] 2. Lifting and Transfer: Start the lifting equipment. The lifting equipment pulls the lifting block 13 up through the second hook 8 and connecting rope 9. The lifting block 13 drives the horizontal plate 17, the top support plate 14 and the anti-slip strip 15 to rise synchronously until the anti-slip strip 15 presses against the inner wall of the sliding groove 7, realizing the relative positioning of the electric pipe 1 and the frame. Then the lifting equipment drives the frame and the electric pipe 1 to be suspended and transferred synchronously until they are transferred to the installation position in the cable trench.

[0039] 3. Fixing the scaffold and connecting the cable conduit: Lower the scaffold to the predetermined installation position in the cable trench, then insert the tapered plug rod 12 at the bottom of the scaffold 6 into the soil to fix and limit the scaffold 6; then control the lifting equipment to loosen the connecting rope 9, and the lifting block 13, horizontal plate 17, top support plate 14 and anti-slip strip 15 descend under their own weight. The anti-slip strip 15 separates from the inner wall of the trough 7, and the roller 11 contacts the inner wall of the trough 7; push the cable conduit 1 with external force, and the cable conduit 1 moves laterally along the roller 11 to adjust the docking position of the cable conduit 1 so that the joint 5 of one set of cable conduit 1 is inserted into the docking groove 2 of another set of cable conduit 1, so as to achieve precise docking of multiple sets of cable conduit 1 and complete the docking operation.

[0040] The scaffolding structure of this invention is rationally designed. Through the coordinated operation of the rolling drag reduction component, the lifting and holding positioning component, and the suspension component, it achieves synchronous suspension, precise positioning, and smooth connection of the electric conduit, solving many drawbacks of existing construction scaffolding. Moreover, each component has a simple structure, is easy to assemble, and is highly practical. It can be adapted to the connection construction of prefabricated high and low voltage integrated electric conduits of different specifications, improving construction efficiency and connection accuracy, and reducing construction costs.
