Description

Technical Field

[0001] This invention is an automatic correction and guidance device for tracked jacking equipment, belonging to the field of bridge construction equipment. Background Technology

[0002] The increasing demands for large-scale, prefabricated, standardized, and automated bridge construction have led to the rapid development of bridge construction techniques. Techniques such as incremental launching, rotation-type construction, and mobile formwork installation can overcome limitations imposed by hydrogeological conditions, enabling factory prefabrication and rapid on-site installation, thus shortening construction periods and reducing costs. Among these, incremental launching technology, as a representative of rapid construction methods, is widely used in urban highway bridges.

[0003] The current construction methods have the following drawbacks:

[0004] 1. The jacking equipment requires manual and mechanical correction, which makes the operation difficult and the safety low.

[0005] 2. The construction process requires a lot of manpower, a lot of equipment and tools, and is costly. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic correction and guidance device for tracked pushing equipment.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] An automatic correction and guiding device for a tracked jacking device includes a tracked jacking device. A tracked jacking device retaining beam is provided on each side of the tracked jacking device. Several hydraulic adjustment mechanisms are provided on the opposite sides of the two tracked jacking device retaining beams. The output ends of the several hydraulic adjustment mechanisms are connected to a guide frame. A box girder is placed on the tracked jacking device. A fixed guide support is provided on one side of the bottom of the box girder. The fixed guide support is slidably connected to the outside of the guide frame.

[0009] Furthermore, a tracked pusher beam tie rod is connected between the two tracked pusher beams.

[0010] Furthermore, a smooth layer is provided on the outer side of the guide frame, and the smooth layer is made of stainless steel.

[0011] Furthermore, the fixed guide support is a maintenance vehicle track base installed at the bottom of the box girder.

[0012] Furthermore, a displacement sensor is installed on the guide frame or the fixed guide support, and the displacement sensor is connected to the hydraulic adjustment mechanism and the electrical control box.

[0013] The beneficial effects of this invention are:

[0014] This invention has a simple structure, is safe and convenient to operate, has a limit function, which is more conducive to the adjustment of dimensional accuracy, and requires no excessive human intervention during operation. The displacement adjustment device automatically adjusts according to the data provided by the displacement sensor to ensure the distance between the guide frame and the jacking equipment. Furthermore, the hydraulic mechanism used to adjust the distance has a low cost and is easy to use.

[0015] This invention addresses the problem of misalignment during the construction process of traditional tracked jacking equipment, improving work efficiency, reducing construction costs, minimizing the input of manpower and materials, and enhancing the accuracy of tracked jacking displacement.

[0016] The present invention, through the design of the positioning mechanism, can form a slot structure with a U-shaped notch on the side of the guide frame. After the box girder is adjusted, the stability of the box girder can be improved by engaging with the fixed guide support through the U-shaped notch.

[0017] Through the design of the driving component, this invention allows the box girder, carrying the fixed guide support, to move along the guide frame. As the fixed guide support moves, it drives the compression block one and compression block two to move synchronously. Compression block one and compression block two will compress the inclined plate two and inclined plate one that penetrate the guide frame. However, because compression block two is longer than compression block one, compression block two will contact the inclined plate one on the guide block that is about to be matched first, triggering the limiting component first. This releases the limiting component from restricting the guide block, allowing the guide block to move when compression block one and inclined plate two are linked together.

[0018] This invention utilizes a limiting component design. The second pressing block contacts the first inclined panel, pressing the first inclined panel on the guide block. The first inclined panel is pressed down by the inclined surface, and as it descends, it drives the inclined block down. The inclined block, through the pressing of the inclined surface, pushes the inclined seat to move linearly. As the inclined seat moves, it pushes several inclined pushing components to move through the receiving groove and press them into the guide inclined surface on the insertion groove. This, in turn, pushes the limiting plate to rise vertically, causing the bottom end of the limiting plate to be pulled out from the guide block inside the guide frame, thus releasing the limiting of the guide block.

[0019] The present invention uses a linkage design so that the first pressing block is pressed together with the second inclined plate on the guide block. Then, the bottom of the second inclined plate presses against the inclined groove, causing the guide block to be stored inside the guide frame. When the fixed guide support moves to a certain position on one side of the guide frame, the two guide blocks corresponding to that position will retract inside the guide frame, so that several guide blocks on the side of the guide frame can form a U-shaped notch slot structure.

[0020] This invention utilizes a shielding component design. During the descent of the inclined block, the inclined block pulls the traction rope, which in turn pulls the moving plate to move and be housed in the receiving slot. As the moving plate moves, the inclined cover plate, connected to the top of the moving plate via a spring hinge, is pressed against the triangular prism fixed to the inner wall of the opening. The pressure from the inclined surface causes the inclined cover plate to rotate and open. Simultaneously, the inclined cover plate, through the traction rope connected to the inclined surface, pulls the slider located in the spring slot to compress the reset spring.

[0021] This invention utilizes the design of a retaining bead groove and a spring retaining bead. Because the length of the second pressing block is longer than that of the first pressing block, the second pressing block will trigger three inclined panels one each time, while the first pressing block will trigger two inclined panels two. This results in an extra guide block being released from its restraint each time. Furthermore, the abutment and limiting action between the retaining bead groove and the spring retaining bead, through the action of abutment force and friction, reduces the possibility of the guide block moving and improves the stability of the device.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0036] Please see Figures 1-11This invention provides a technical solution for an automatic correction and guidance device for a tracked jacking device, comprising a tracked jacking device 3, with a tracked jacking device stop beam 2 on each side of the tracked jacking device 3, and a tracked jacking device stop beam tie rod 4 connecting the two tracked jacking device stop beams 2. Several hydraulic adjustment mechanisms 5 are provided on opposite sides of the two tracked jacking device stop beams 2, and the output ends of the several hydraulic adjustment mechanisms 5 are connected to a guide frame 6. A smooth layer made of stainless steel is provided on the outer side of the guide frame 6. A box girder 1 is placed on the tracked jacking device 3, and a fixed guide support 7 is provided on one side of the bottom of the box girder 1. The fixed guide support 7 is slidably connected to the outer side of the guide frame 6, and the fixed guide support 7 is a maintenance vehicle track base installed at the bottom of the box girder 1.

[0037] See Figures 3-4 A positioning mechanism is provided between the guide frame 6 and the fixed guide support 7. The positioning mechanism includes a driving component, a linkage component, and a limiting component. The driving component includes a pressing block 9 fixed to the side of the fixed guide support 7. The pressing block 9 is located above the guide frame 6. A second pressing block 10 is provided on the side of the pressing block 9. The bottom of the second pressing block 10 near the pressing block 9 has a movable groove 11. Through the design of the driving component, as the box girder 1 moves along the guide frame 6 with the fixed guide support 7, the positioning mechanism moves with the fixed guide support 7. When the fixed guide support 7 moves, it will drive the extrusion block 1 9 and extrusion block 2 10 to move synchronously. The extrusion block 1 9 and extrusion block 2 10 will extrude the inclined plate 2 36 and inclined plate 19 above the guide frame 6. However, because the length of extrusion block 2 10 is longer than that of extrusion block 1 9, extrusion block 2 10 will contact the inclined plate 19 on the guide block 12 that is about to be matched first, triggering the limiting member first, and then releasing the limiting member from limiting the guide block 12. This allows the guide block 12 to be movable when the extrusion block 1 9 and the inclined plate 2 36 are linked together.

[0038] See Figure 5 , Figure 6The linkage includes an inner cavity formed inside the guide frame 6. A guide block 12 is laterally slidably connected inside the inner cavity. A plurality of damping springs 14 are connected between one end of the guide block 12 and the inner wall of the inner cavity. A plurality of stroke posts 13 that cooperate with the damping springs 14 are also provided on the outer surface of the end of the guide block 12. The other end of the guide block 12 extends to the outside of the guide frame 6. A sloping groove 15 is formed on one side of the top of the guide block 12. An inlet and outlet extending to the top of the guide frame 6 are formed on one side of the top of the inner cavity. A sloping plate 36 is slidably connected inside the inlet and outlet. The bottom side of the second inclined panel 36 is provided with a limiting protrusion, and the bottom of the second inclined panel 36 extends into the inclined groove 15. Through the design of the linkage, the first pressing block 9 will press together with the second inclined panel 36 on the guide block 12, and then the bottom of the second inclined panel 36 will press against the inclined groove 15 to make the guide block 12 retract into the guide frame 6. Then, when the fixed guide support 7 moves to a certain position on one side of the guide frame 6, the two guide blocks 12 corresponding to that position will retract into the guide frame 6, so that several guide blocks 12 on the side of the guide frame 6 can form a U-shaped notch slot structure.

[0039] See Figures 7-9The limiting component includes several fixed shells 35 fixed to the top of the guide frame 6. Each fixed shell 35 corresponds to a number of guide blocks 12. A movable cavity 17 is formed on one side of the top of each fixed shell 35. An inclined seat 21 is laterally slidably connected inside the movable cavity 17. Several inclined pushers 22 and several damping springs 24 are provided on the flat surface of the inclined seat 21. The damping springs 24 are installed inside the movable cavity 17. The inclined pushers 22 are located above the damping springs 24. Several [unclear text - possibly related to a device or mechanism] are provided on the outer surface of the inclined seat 21 below the inclined pushers 22. The stroke column 23, which cooperates with the damping spring 24, has a vertically slidable inclined plate 19 at the top opening of the movable cavity 17. The inclined end of the inclined plate 19 extends through to the top of the fixed shell 35. An inclined block 20 is fixed to one end of the inclined plate 19 inside the movable cavity 17. The inclined block 20 is vertically slidably connected inside the movable cavity 17. The inclined end of the inclined block 20 is pressed together with the inclined surface of the inclined seat 21. The limiting member also includes a storage groove 18 formed on one side of the bottom of the fixed shell 35. The top of the storage groove 18 has a through-hole extending to the top of the fixed shell 35. The opening 30, the storage slot 18 is connected to the movable cavity 17 on one side through several connecting slots, the storage slot 18 is vertically slidably connected to a limiting plate 25, the top of the guide block 12 is provided with a limiting slot 16 that cooperates with the limiting plate 25, the limiting plate 25 is provided with several insertion slots 26, the top of the insertion slot 26 is provided with a guide slope 27, the bottom of the insertion slot 26 is provided with a through hole 28 that cooperates with the inclined push member 22, the inclined end of the inclined push member 22 passes through the connecting slots and is pressed together with the guide slope 27 in the insertion slot 26; through the limiting The design of the positioning component involves the compression block 10 contacting the inclined plate 19, which compresses the inclined plate 19 on the guide block 12. The inclined plate 19 is compressed and lowered under the action of the inclined surface. As the inclined plate 19 descends, it drives the inclined block 20 to descend. The inclined block 20 will push the inclined seat 21 to move linearly through the compression of the inclined surface. As the inclined seat 21 moves, it will push several inclined pushers 22 to move and penetrate into the storage groove 18 and compress into the guide inclined surface 27 on the insertion groove 26. This will push the limiting plate 25 to rise vertically, so that the bottom end of the limiting plate 25 is pulled out from the guide block 12 inside the guide frame 6, releasing the limitation on the guide block 12.

[0040] See Figure 7 , Figure 10 , Figure 11The opening 30 is provided with a shielding assembly, which includes a receiving groove 29 formed on the inner wall of one side of the opening 30 and a triangular prism 34 fixed on the inner wall of the opening 30 and located above the receiving groove 29. A movable plate 32 is slidably connected to the receiving groove 29. The end of the movable plate 32 is engaged with the inner wall of the other side of the opening 30. A beveled cover plate 33 is hinged to the top side of the movable plate 32 by a spring hinge. The beveled end of the beveled cover plate 33 fits with the beveled end of the triangular prism 34. One end of a traction rope 39 is connected to the beveled end of the beveled cover plate 33. The other end of the traction rope 39 passes through the triangular prism 34 and extends into a spring groove in the inner wall of the fixed shell 35, where it is connected and fixed to a slider 40. The slider 40 is slidably connected in the spring groove. The outer surface of the traction rope 39 and located on the slider 40 are connected to the spring groove. A reset spring 41 is sleeved between block 40 and the inner wall of the spring groove. A traction rope 31 is fixed at the middle of one end of the moving plate 32 inside the receiving groove 29. The end of the traction rope 31 extends movably through the inside of the movable cavity 17 and is connected and fixed to the top of the inclined block 20. Through the design of the shielding component, during the descent of the inclined block 20, the inclined block 20 will pull the traction rope 31, and the traction rope 31 will pull the moving plate 32 to move and be stored in the receiving groove 29. During the movement of the moving plate 32, the inclined cover plate 33 connected to the top of the moving plate 32 by the spring hinge will be pressed together with the triangular prism 34 fixed on the inner wall of the opening 30. The inclined cover plate 33 and the triangular prism 34 will cause the inclined cover plate 33 to rotate and open due to the compression of the inclined surface. At the same time, the inclined cover plate 33 will pull the slider located in the spring groove to squeeze the reset spring through the traction rope connected to the inclined surface.

[0041] See Figure 5 The guide block 12 has a ball-locking groove 37 on one outer surface, and a spring-loaded ball 38 is provided in the ball-locking groove 37. The guide block 12 has several grooves on the other outer surface that cooperate with the spring-loaded ball 38. Due to the design of the ball-locking groove 37 and the spring-loaded ball 38, since the length of the second extrusion block 10 is longer than that of the first extrusion block 9, the second extrusion block 10 will extrude and trigger three inclined plates 19 each time, and the first extrusion block 9 will extrude and trigger two inclined plates 26. This results in one more guide block 12 being released from restriction each time. Furthermore, the abutment and limiting between the ball-locking groove 37 and the spring-loaded ball 38, through the action of abutment force and friction, reduces the possibility of movement of the guide block 12 and improves the stability of the device.

[0042] In use, firstly, the fixed guide support 7 is installed on the box girder 1; secondly, the two tracked jacking device retaining beams 2 and the tracked jacking device 3 are installed in place, and the tracked jacking device retaining beam tie rod 4 is adjusted before installing the guide frame 6; then, the box girder 1 is placed on the tracked jacking device 3, and the hydraulic adjustment mechanism 5 on the guide frame 6 is adjusted to maintain a certain gap between the guide frame 6 and the fixed guide support 7, and the displacement is monitored by the displacement sensor 8; after the equipment is adjusted, the tracked jacking device 3 is tested. The tracked jacking device 3 moves forward, driving the box girder 1 forward during the operation. The fixed guide support 7 on the box girder 1 moves forward with the movement of the box girder 1, and at the same time, the fixed guide support 7 slides forward along the guide frame 6. When the displacement... When sensor 8 detects a displacement of the equipment, it feeds the information back to hydraulic adjustment mechanism 5. Hydraulic adjustment mechanism 5 automatically adjusts the distance between the tracked jacking equipment's retaining beam 2 and guide frame 6. Through the pushing force of hydraulic adjustment mechanism 5 and the reaction force provided by fixed guide support 7, the equipment is adjusted to the predetermined position. Fixed guide support 7 serves both as a guide and as a limiter on the lateral displacement of box girder 1. During the movement of box girder 1 along guide frame 6 with fixed guide support 7, the fixed guide support 7 drives the compression block 9 and compression block 10 to move synchronously. Compression blocks 9 and 10 compress and penetrate the inclined surface above guide frame 6. Plate 2 36 and inclined plate 1 19, however, because the length of extrusion block 2 10 is longer than that of extrusion block 1 9, extrusion block 2 10 will contact the inclined plate 19 on the guide block 12 that is about to be matched first, and thus extrude the inclined plate 19 on the guide block 12 first. The inclined plate 19 is extruded and descended under the action of the inclined surface. As the inclined plate 19 descends, it drives the inclined block 20 to descend. The inclined block 20 will push the inclined seat 21 to move linearly through the extrusion of the inclined surface. As the inclined seat 21 moves, it will push several inclined pushers 22 to move and penetrate into the receiving groove 18 and extrude into the guide inclined surface 27 on the insertion groove 26, thereby pushing the limiting plate 25 to rise vertically, so that the bottom end of the limiting plate 25 exits from the guide frame. The guide block 12 inside the guide frame 6 is pulled out, releasing the restriction on the guide block 12. Then, the pressing block 1 9 will press together with the inclined plate 2 36 on the guide block 12. Then, the bottom of the inclined plate 2 36 presses against the inclined groove 15, so that the guide block 12 is stored inside the guide frame 6. Then, when the fixed guide support 7 moves to a certain position on one side of the guide frame 6, the two guide blocks 12 corresponding to that position will retract inside the guide frame 6, so that several guide blocks 12 on the side of the guide frame 6 can form a U-shaped notch slot structure. Then, the hydraulic adjustment mechanism 5 pushes the guide frame 6 to move, so that the guide frame 6 with the U-shaped notch matches the fixed guide support 7, forming a locking and limiting effect.

[0043] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
