Description

Technical Field

[0001] The invention relates to the technical field of rail pushing, in particular to a heavy object rail pushing mechanism for a building. Background Art

[0002] In the construction of large-scale building structures, bridge rotations, and heavy industrial equipment installation, heavy-weight jacking technology is a core operation. Traditional processes rely on coordinated lifting by groups of hydraulic jacks and the alternating laying of sliding pads. Pushing is performed by adding reaction points to the back of the load. This requires high manual labor, dozens of workers are required on-site, and construction efficiency is low, with only about 10 meters of jacking per day. Accumulated errors can easily cause heavy objects to deviate from the track and even cause structural instability. Although continuous jacking devices have been partially mechanized in recent years, they are still limited by three bottlenecks. First, the anti-recoil mechanism often uses mechanical latches or friction brakes, which are prone to sudden slippage under loads of thousands of tons. Second, the jacking process lacks real-time posture control capabilities, and uneven force on the bottom surface of the heavy object may damage the main structure. Third, the track system lacks scalability and is difficult to adapt to complex construction site environments. Although existing technologies have proposed the concept of modular tracks, they have not solved the problem of integrating jacking and fine-tuning functions. Hydraulic suspension and three-dimensional correction still rely on independent equipment.

[0003] The core problems exposed by the above background technology are concentrated in three aspects. First, the traditional anti-retreat mechanism has an instantaneous unloading window when the cylinder returns. The risk of inertial sliding of the heavy object cannot be eradicated, forcing the project to slow down. Secondly, the jacking process only realizes one-way displacement. The tilt, yaw and other posture deviations of the heavy object require manual intervention after stopping the work, which greatly prolongs the construction period. In addition, the fixed track is difficult to expand quickly. When the ground is uneven, the hydraulic cylinder is easily damaged by lateral force, and the traditional slide plate is cumbersome to replace after wear. More importantly, the existing technology disassembles "propulsion-anti-retreat-leveling-correction" into independent processes, resulting in redundant equipment and complex control. Although some existing jacking systems integrate hydraulic drive, the heavy object directly and rigidly contacts the track, and the support reaction force distribution cannot be dynamically adjusted, which can easily cause local stress concentration. Therefore, a building heavy object rail jacking mechanism is proposed. Summary of the Invention

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1-8As shown, an embodiment of the present invention proposes a building heavy object rail pushing mechanism, comprising an extended rail 1, a reaction seat 8 and a sliding shoe 18. The extended rail 1 serves as the basic guide component of the entire pushing mechanism, providing precise rail guidance for the movement of the sliding shoe 18. The end of the extended rail 1 is spliced ​​with an additional rail 2. The additional rail 2 can flexibly extend the rail length according to actual construction needs to meet the requirements of pushing operations at different distances. Both sides of the extended rail 1 and the additional rail 2 are fixedly connected with a connecting block 3. The connecting block 3 serves as a connecting component between rails to ensure structural stability when multiple sections of rails are spliced. The outside of the connecting block 3 is provided with a connecting hole 4, which is used to pass a fastening bolt. In order to ensure reliable connection between the existing rails, multiple groups of detachably connected sliding plates 5 are installed on the inner sides of the extended rail 1 and the added rail 2. The sliding plates 5 can be replaced separately as wearing parts, which effectively reduces maintenance costs. At the same time, the sliding plates 5 are made of stainless steel and PTFE or MGA materials to form friction pairs, which reduces the sliding friction coefficient during pushing. Its smooth surface can reduce the friction resistance of the sliding shoe 18 when it moves. The inner side of the added rail 2 is fixedly connected with multiple groups of protrusions 6 arranged in an array. The protrusions 6 serve as positioning structures to ensure the accuracy of the installation position of the sliding plate 5. A groove 7 is provided at the bottom of the sliding plate 5, and the groove 7 matches the protrusion 6. This concave-convex matching structure can not only accurately position, but also prevent the sliding plate 5 from displacement when subjected to force.

[0034] like Figure 4 As shown, one side of the reaction seat 8 is fixedly connected to a pushing cylinder 9. The pushing cylinder 9 serves as the main power source and provides stable thrust output for the entire pushing process. One side of the pushing cylinder 9 is fixedly connected to a connecting plate 10. The connecting plate 10 serves as a force transmission component and evenly transmits the thrust of the pushing cylinder 9 to the reaction seat 8. Two groups of symmetrically arranged reinforcement rods 11 are fixedly connected between the connecting plate 10 and the reaction seat 8. The reinforcement rods 11 significantly enhance the rigidity of the connection part to prevent structural deformation under high-pressure working conditions. Both sides of the reaction seat 8 are fixedly connected to mounting seats 12. The mounting seats 12 provide an installation basis for the fixing frame 14 to ensure the stable operation of the anti-retreat mechanism. The upper side of the mounting seat 12 is detachably connected to a sealing plate 13. The sealing plate 13 plays a protective role to prevent dust and other impurities from entering the internal mechanism and affecting operation.

[0035] like Figure 5As shown, the inner side of the mounting seat 12 is fixedly connected to a fixing frame 14, which serves as the main frame of the anti-retreat mechanism and bears the reaction force during the pushing process. The outside of the fixing frame 14 is provided with multiple groups of symmetrically arranged slide grooves 15, and the slide grooves 15 provide a precise guide path for the ratchet block 16. The inner side of the slide groove 15 is slidably connected to the ratchet block 16, and the ratchet block 16 has a trapezoidal plate structure. This special shape enables it to automatically embed into the positioning groove 17 to achieve one-way self-locking. The upper side of the extended track 1 and the added track 2 is provided with multiple groups of equally spaced positioning grooves 17, and the ratchet block 16 matches the positioning groove 17. This matching relationship ensures that the heavy objects can be reliably prevented from retreating during the pushing process.

[0036] like Figure 6 As shown, the outer shell of the sliding shoe 18 is composed of a base 19, a side plate 27, a cover plate 28 and a cover shell 29. This modular design facilitates manufacturing and maintenance. The base 19 is connected to the output shaft of the jacking cylinder 9, and as a force-bearing component, it transmits the thrust to the entire sliding shoe 18. The outside of the base 19 is fixedly connected to a connecting seat 20. The connecting seat 20 provides a hinge fulcrum, allowing a certain angle change between the jacking cylinder 9 and the sliding shoe 18. The end of the output shaft of the jacking cylinder 9 is fixedly connected to a connecting member 21, and the connecting member 21 is hinged to the connecting seat 20. This hinged structure can adapt to the angular deviation caused by the unevenness of the track.

[0037] like Figure 8 As shown, the inner side of the sliding shoe 18 is fixedly connected with a sliding seat 22, which serves as an installation platform for the internal mechanism to ensure the relative position accuracy of each functional component. A lateral correction mechanism and a lifting mechanism are installed on the inner side of the sliding shoe 18. The lateral correction mechanism is used to correct the lateral deviation of the sliding shoe 18 in real time. The lateral correction mechanism includes a cylinder 23 and a piston rod 24. The cylinder 23 is fixedly connected to the outside of the sliding seat 22, and the number of cylinders 23 is two groups and they are symmetrically arranged. This symmetrical arrangement can produce a balanced correction force. The piston rod 24 is fixedly connected to both sides of the cylinder 23. The telescopic movement of the piston rod 24 directly pushes the sliding shoe 18 to adjust its lateral position.

[0038] like Figure 8 As shown, the jacking mechanism includes a mounting sleeve 25, a jacking cylinder 26, a ball saddle 30 and a seat plate 31. The mounting sleeve 25 is fixedly connected to the upper side of the sliding seat 22 to provide a stable mounting base for the jacking cylinder 26. The jacking cylinder 26 is fixedly connected to the inner side of the mounting sleeve 25. As a jacking power source, it can accurately control the lifting height. The ball saddle 30 is fixedly connected to the top output shaft end of the jacking cylinder 26. Its spherical structure allows the seat plate 31 to be fine-tuned at multiple angles. The outside of the ball saddle 30 is slidably connected to the seat plate 31, and the seat plate 31 abuts against the upper side of the cover shell 29 and the cover plate 28. This design enables heavy objects to maintain dynamic balance during the jacking process.

[0039] like Figure 6 As shown, the outside of the side panel 27 is provided with multiple groups of transversely arranged oil port interfaces 32 and signal line interfaces 33. The oil port interfaces 32 are used to connect hydraulic pipelines, and the signal line interfaces 33 are convenient for connecting various sensors to realize intelligent control.

[0040] like Figure 4 as well as Figure 6 As shown, the bottom of the reaction seat 8 and the sliding shoe 18 are fixedly connected to a boat-shaped bottom plate 34, and both ends of the boat-shaped bottom plate 34 are bent obliquely upward. This streamlined design can effectively reduce the movement resistance and prevent foreign objects from getting stuck and affecting the smoothness of movement.

[0041] In this embodiment, the building heavy object rail pushing mechanism adopts a modular track system and multi-level hydraulic collaborative control technology to achieve efficient pushing and precise positioning of heavy objects. Its working principle starts from the dynamic expansion of the track system. The extended track 1 and the added track 2 are quickly spliced ​​together through the connecting block 3 and the connecting hole 4 to form a continuous guide track. The detachable sliding plate 5 installed on the inner side of the track achieves rapid positioning through the precise cooperation between the bottom groove 7 and the track protrusion 6. This modular design not only adapts to different pushing distance requirements, but its low friction characteristics also significantly reduce power loss. The positioning grooves 17 evenly distributed on the top surface of the track and the ratchet block 16 on the reaction seat 8 constitute the core anti-retreat mechanism. When the pushing cylinder 9 pushes the sliding shoe 18 forward through the connecting piece 21, the trapezoidal ratchet block 16 in the fixed frame 14 automatically embeds the positioning groove 17 in the slide groove 15 to form a mechanical one-way lock; when the cylinder retracts, the inclined surface of the ratchet block 16 is pressed back to achieve a cyclic pushing step.

[0042] The sliding shoe 18 is the core motion carrier, and its shell is assembled from a base 19, side panels 27, cover 28 and cover 29 to form a lightweight box. The base 19 is connected to the output shaft of the push cylinder 9 through an articulated connection seat 20 to ensure that the thrust can adapt to the track plane deviation during transmission. The lateral correction mechanism integrated in the sliding shoe 18 drives the piston rod 24 to extend and retract in real time through the symmetrically arranged cylinders 23. When the sensor detects that the sliding seat 22 has a lateral deviation, the hydraulic system automatically adjusts the stroke of the piston rod 24 on both sides to make the weight The object is always pushed along the center line of the track. At the same time, the jacking mechanism plays a key suspension function. The jacking cylinder 26 in the installation sleeve 25 pushes the ball saddle 30 and the seat plate 31. The universal rotation characteristics of the ball saddle 30 form a controllable elastic support between the weight and the track. This design puts the weight in a "hydraulic suspension" state during the jacking process. Combined with the real-time load data received by the oil port interface 32 and the signal line interface 33 on the side panel 27, the system can dynamically adjust the jacking pressure to ensure that the bottom surface of the weight is evenly stressed to avoid local overload.

[0043] After completing the jacking, the system demonstrates multi-dimensional fine-tuning capabilities. The jacking mechanism achieves millimeter-level lifting and lowering adjustment through graded pressure control. The lateral correction system drives the sliding shoe 18 to slightly move and correct the plane position, and the compound movement of the ball saddle 30 and the seat plate 31 supports pitch, yaw and other angle adjustments. The reaction seat 8 and the boat-shaped bottom plate 34 at the bottom of the sliding shoe 18 are designed with both ends bent upward. The boat-shaped bottom plate 34 can effectively reduce the track jamming phenomenon caused by the unevenness of the track surface, and form a fluid dynamic sliding surface during the jacking process, which effectively reduces the ground friction resistance. The entire system realizes push-pull dual-mode operation through the two-way control of the hydraulic system. The quick replacement feature of the sliding plate 5 greatly extends the service life of the track. Finally, under the scheduling of the automated control system, the mechanism integrates the scattered propulsion, anti-retreat, leveling and correction functions in the traditional jacking operation into a single device, and achieves a breakthrough in the six-degree-of-freedom precise positioning in three-dimensional space while ensuring the safety of the heavy object structure.
