Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of beam pouring equipment, in particular to a side mold walking and mold adjusting system of a bridge builder, a bridge builder and a bridge manufacturing method. BACKGROUND

[0002] In the side mold moving operation of the bridge builder, the prior art mainly relies on two schemes, and both have obvious defects: First, the overall jacking and translation scheme. This scheme cooperates multiple oil cylinders to jack up the side mold, and then drives the main truss and the side mold to walk synchronously with the help of the driving system on the beam surface. However, the core problem of this scheme is that the synchronous walking control is difficult, because the jacking force output of multiple oil cylinders is prone to deviation, and it is difficult to achieve absolute synchronization when the driving system drives the main truss and the side mold to move, which leads to the deviation of the side mold walking track, and in severe cases, it can cause the side mold and the main truss to be stuck, which not only interrupts the construction process, but also can cause damage to the equipment structure, increase the maintenance cost and the risk of delay. Second, the hanging translation scheme. This scheme sets multiple anchoring lifting points above the beam surface, and uses the lifting points to realize the hanging and movement of the guide beam and the side mold. However, this scheme has multiple defects: first, the hanging stability is poor, the stress distribution of multiple anchoring lifting points is prone to imbalance, and the hanging structure has weak resistance to external disturbances (such as wind and construction vibration), which leads to the shaking of the side mold during movement; second, positioning is difficult and time-consuming, and accurate positioning of the side mold after movement requires multiple manual adjustments, which is a tedious operation process that greatly reduces construction efficiency; third, there are serious safety hazards, and the anchoring lifting points are prone to looseness under long-term load, which may cause the guide beam and the side mold to fall, posing a serious threat to the safety of construction personnel and equipment.

[0054] Current side formwork movement schemes, which use overall suspension or multi-point jacking, have inaccurate motion control, rely heavily on manual operation and mechanical adjustments (such as jacks and chain hoists), resulting in high labor intensity, low automation, and limited bridge segment length.

[0055] A side formwork traveling and adjusting system for a bridge-building machine according to an embodiment of the first aspect of this application, such as... Figure 1 and Figure 2 As shown, the side formwork traveling and adjusting system of the bridge-building machine includes: a track assembly 1 extending along the length of the beam 81; a trolley assembly 2 movably mounted on the track assembly 1; a slider 3 mounted on the trolley assembly 2 and capable of sliding relative to the trolley assembly 2 in a horizontal plane in a direction perpendicular to the length of the track assembly 1; a lifting assembly 4 mounted on the slider 3 and moving with the slider 3; the height of the lifting assembly 4 is adjustable; and a supporting beam assembly 5 mounted on the lifting assembly 4 to support the side formwork system 85 and form a rigid whole with the side formwork system 85, ensuring that the side formwork system 85 does not deform during movement and adjustment. The side formwork system 85 includes a side formwork back frame 851 and a side formwork template 852. The supporting beam assembly 5 supports the side formwork back frame 851, and the side formwork back frame 851 supports the side formwork template 852.

[0056] The slider 3 can slide relative to the trolley assembly 2 in a horizontal plane along a direction perpendicular to the length of the track assembly 1. It should be understood that in actual engineering, due to factors such as force, the lower part of the C-shaped limiting end 714 may be slightly tilted and not completely horizontal. In this case, the relative movement direction of the slider 3 will have a certain angle with the horizontal plane, but it should be understood that this situation is still included in the scope defined above as "the slider 3 can slide relative to the trolley assembly 2 in a horizontal plane along a direction perpendicular to the length of the track assembly 1".

[0057] like Figure 8 As shown, the track assembly 1 extends along the length of the beam 81, forming a motion mechanism along the length of the beam 81 with the trolley assembly 2 movably mounted on it. The trolley assembly 2 moves along the fixed trajectory of the track assembly 1, ensuring a stable power transmission path and smooth movement of the side mold system 85 along the length of the beam 81.

[0058] The coordinated arrangement of slider 3 and trolley assembly 2 enables the side formwork system 85 to be positioned in the horizontal plane along the length direction perpendicular to the track assembly 1 (i.e., the width direction of the beam 81). Slider 3 can slide smoothly relative to trolley assembly 2, allowing for direct fine-tuning of the beam 81's position in the side formwork system 85 across the width direction. This eliminates the need for multiple manual disassemblies or adjustments to the lifting points, significantly reducing positioning time and improving positioning accuracy. Furthermore, the connection structure between slider 3 and trolley assembly 2 is stable, with no significant shaking during sliding, avoiding the inefficiency caused by cumbersome positioning operations and reducing safety risks during manual operation.

[0059] The lifting assembly 4 can be an oil cylinder installed on the sliding block 3 and adjustable in height, cooperates with the sliding block 3 and the trolley assembly 2 to form a position adjustment system in three-dimensional direction, decouples the movement of the side mold system 85 with three degrees of freedom, forms an independently controllable length, width and height adjustment mechanism, and precisely controls different position requirements of the side mold system 85 respectively, to ensure the fitting accuracy of the side mold system 85 and the beam body 81 structure, reduce the construction rework caused by position deviation, and further improve the bridge construction quality.

[0060] The supporting beam assembly 5 is installed on the lifting assembly 4 and used to support the side mold system 85, forms a stable supporting structure for the side mold system 85, effectively improves the poor stability and prominent safety hidden trouble of the existing hanging translation scheme. Compared with the force bearing mode of the hanging point suspension type, the supporting beam assembly 5 is connected with the side mold system 85 through surface contact or multi-point support, the force is more uniform, the weight load of the side mold system 85 can be dispersed, the deformation of the side mold system 85 or the loosening of the supporting structure caused by local load concentration can be avoided; at the same time, the connection between the supporting beam assembly 5 and the lifting assembly 4 is reliable, the stable state of the side mold system 85 can be maintained under the action of construction vibration or external disturbance, the safety risk of falling or displacement of the side mold system 85 is reduced, and the safety of construction personnel and equipment is ensured.

[0061] The cooperation of each component also improves the construction adaptability and structural reliability of the system. The track assembly 1 can be flexibly set to extend the range according to the construction length of the beam body 81, and the moving stroke of the trolley assembly 2 can cover the entire construction section; the sliding stroke of the sliding block 3 and the height adjustment range of the lifting assembly 4 can be adaptively designed according to the width and height specifications of the beam body 81, without the need to design special equipment for different sizes of beam body 81, forming a universal side mold system 85 adjustment system, reducing the equipment investment and replacement cost. The component structure of the whole system is simple, the cooperation relationship between each part is clear and the connection is reliable, the movement of the trolley on the track, the sliding of the sliding block 3 and the height adjustment of the lifting assembly 4 can all maintain a stable state, reducing the friction loss and jamming phenomenon between parts, prolonging the service life of the equipment, further ensuring the continuity of the construction process, and improving the overall construction efficiency.

[0062] According to one embodiment of the present application, as shown in Figures 2 to 4 The trolley assembly 2 includes: a trolley body 21, on which the sliding block 3 is installed; a walking wheel 22, which is installed at the bottom of the trolley body 21 and cooperates with the track assembly 1; and a limiting assembly 23, which is installed on the walking wheel 22 and cooperates with the track assembly 1 to limit the separation of the trolley assembly 2 and the track assembly 1. The walking wheel 22 can have various driving modes, such as: the walking wheel 22 can be in transmission connection with a driving mechanism, and the driving mechanism drives the walking wheel 22 to rotate; or, a driving mechanism in transmission connection with the walking wheel 22 can not be provided, and driving can be realized through a traction device or a pushing device connected with the trolley assembly 2.

[0063] The car body 21 can be a box girder structure. For example... Figure 2 As shown, the vehicle body 21 serves as the basic load-bearing structure of the trolley assembly 2, directly mounting the slider 3 and providing a stable mounting reference and support platform for the slider 3. The vehicle body 21 adapts to the sliding requirements of the slider 3 and simultaneously bears the combined load of the slider 3, lifting assembly 4, support beam assembly 5, and side mold system 85. The stable structural form ensures that the upper components will not experience significant deformation or displacement during movement, avoiding positional deviation of the side mold system 85 due to instability of the load-bearing structure.

[0064] The traveling wheels 22 are installed at the bottom of the vehicle body 21 and cooperate with the track assembly 1, converting the sliding friction between the vehicle body 21 and the track assembly 1 into rolling friction. This reduces the resistance when the trolley assembly 2 moves along the track assembly 1, ensuring the smooth movement of the trolley assembly 2 along the length of the beam 81. Simultaneously, the cooperation between the traveling wheels 22 and the track assembly 1 forms a clear motion trajectory, limiting the lateral displacement of the trolley assembly 2 during movement and improving the accuracy of the side mold system 85's position adjustment along the length of the beam 81.

[0065] The limiting component 23 is installed on the traveling wheel 22 and cooperates with the track component 1 to form an anti-derailment protection structure for the trolley component 2, effectively improving the problems of poor stability and prominent safety hazards in the existing suspended translation scheme. Through its cooperation with the track component 1, the limiting component 23 restricts the displacement of the trolley component 2 in the direction perpendicular to the track plane, preventing derailment during movement and ensuring the safe movement of the trolley component 2. Simultaneously, the synergistic effect of the limiting component 23 and the traveling wheel 22 further enhances the stability of the cooperation between the traveling wheel 22 and the track component 1, preventing lateral deviation of the traveling wheel 22 during rolling, indirectly improving the accuracy of the side formwork system 85 position adjustment, reducing the risk of damage to the side formwork system 85 and construction accidents caused by derailment or deviation of the trolley component 2, and providing support for the safety of construction personnel and equipment.

[0066] The coordinated action of the vehicle body 21, the traveling wheels 22, and the limiting components 23 forms a stable, precise, and reliable trolley assembly 2. This not only solves the problems of poor synchronization, insufficient stability, and prominent safety hazards in the two existing solutions, but also provides key support for the three-dimensional adjustment function of the entire side formwork traveling and adjusting system. Through the load-bearing capacity of the vehicle body 21, the smooth movement of the traveling wheels 22, and the safety protection of the limiting components 23, the side formwork system 85 can maintain a precise trajectory and avoid structural separation or jamming when moving along the length of the beam 81. At the same time, in conjunction with the slider 3, the lifting components 4, and the supporting beam components 5, the decoupled adjustment of the three degrees of freedom of the side formwork system 85 can be achieved, further improving the accuracy of the position adjustment of the side formwork system 85 and the construction efficiency, and ensuring the quality and safety of bridge construction.

[0067] The walking wheel 22 can replace the existing metal wheel with a polyurethane wheel, which has good elasticity and wear resistance, can reduce the impact noise when the walking wheel 22 cooperates with the track assembly 1, and can reduce the wear on the surface of the track assembly 1, thereby prolonging the service life of the track assembly 1 and the walking wheel 22. In addition, the anti-skid performance of the polyurethane wheel is better than that of the metal wheel, which can further improve the stability of the movement of the trolley assembly 2.

[0068] According to one embodiment of the present application, as shown in Figure 2 and Figure 7 , the track assembly 1 includes a first track 11 and a second track 12 arranged side by side along the width direction of the beam body 81, and the first track 11 is located between the second track 12 and the main body portion 811 of the beam body 81; the limiting assembly 23 includes two adjacent clamping wheels 231, and a vertical gap 232 is formed between the two clamping wheels 231, and a horizontal gap 233 is formed between the two clamping wheels 231 and the walking wheel 22; the second track 12 includes a horizontal support plate 121 and a vertical connecting plate 122 connected together, the horizontal support plate 121 is located in the horizontal gap 233, and the vertical connecting plate 122 is located in the vertical gap 232, so as to limit the lifting of the side of the trolley assembly 2 away from the main body portion 811 of the beam body 81. The first track 11 and the second track 12 can be connected by a connecting beam 14 (or a connecting plate).

[0069] In actual application, as shown in Figure 1 , the side of the vehicle body 21 close to the beam body 81 (i.e., the side of the vehicle body 21 close to the first track 11) is hung with a bottom basket system 84 through a hanging system 83 (such as a hanging rope or a hanging belt). The side of the vehicle body 21 close to the first track 11 bears a large load due to the bottom basket system 84, which is easy to cause the side of the vehicle body 21 away from the main body of the beam body 81 (i.e., the side of the vehicle body 21 close to the second track 12) to be lifted and tilted. The first track 11 and the second track 12 are arranged side by side along the width direction of the beam body 81, and the first track 11 is located between the second track 12 and the main body portion 811 of the beam body 81, which is suitable for the load distribution characteristics of the vehicle body 21 and provides a reasonable structural basis for the subsequent limiting structure.

[0070] As shown in Figure 4 , the second track 12 includes a horizontal support plate 121 and a vertical connecting plate 122 connected together, and the horizontal support plate 121 is embedded in the horizontal gap 233 formed by the two clamping wheels 231 and the walking wheel 22, and the vertical connecting plate 122 is embedded in the vertical gap 232 formed by the two clamping wheels 231. The vertical gap 232 vertically restricts the vertical connecting plate 122, limits the left and right deviation of the vehicle body 21 in the horizontal direction, ensures that the second track 12 always maintains a state of being in close contact with the walking wheel 22 and the clamping wheel 231, and avoids the force imbalance on the side of the vehicle body 21 close to the second track 12.

[0071] The walking wheel 22 and the two clamping wheels 231 form a transverse gap 233 between them, and the transverse support plate 121 of the second track 12 is located in the transverse gap 233. This matching structure directly acts on the risk of lifting the second track 12 side of the vehicle body 21. Because the first track 11 side of the vehicle body 21 is pressed downward by a large load, the second track 12 side is prone to lifting upward. The two clamping wheels 231 abut against the lower surface of the transverse support plate 121 to prevent the vehicle body 21 on the second track 12 side from lifting upward, avoiding the vehicle body 21 from tilting due to uneven load, solving the problem of insufficient stability caused by excessive load on one side of the vehicle body 21, providing safety constraints in the vertical direction for the smooth movement of the trolley assembly 2 along the track assembly 1, and ensuring the safety of equipment and personnel during construction.

[0072] The cooperation between the track assembly 1 and the limiting assembly 23 can also enhance the overall stability of the movement of the trolley assembly 2. The vertical gap 232 vertically constrains the vertical connecting plate 122, and the transverse gap 233 transversely constrains the transverse support plate 121, forming a two-way limiting of the vehicle body 21 on the second track 12 side, preventing lifting and deviation, so that the vehicle body 21 can still maintain a horizontal posture under uneven load, avoiding poor contact between the walking wheel 22 and the track assembly 1 due to the inclination of the vehicle body 21, and further reducing the situation of jamming or accelerated wear of the walking wheel 22.

[0073] As shown in Figure 2 , the first track 11 can adopt the same structure as the second track 12, so that the track assembly 1 can maintain consistent matching precision under different load scenarios, without the need to design separate adaptation structures for the first track 11, improving the structural versatility and construction adaptability of the system, and reducing equipment manufacturing and maintenance costs.

[0074] According to an embodiment of the present application, as shown in Figure 3 , the side mold walking and mold adjusting system of the bridge building machine further includes a support column assembly 61, the upper end of which is connected to the lower part of the support beam assembly 5, and the height of the support column assembly 61 is adjustable; the support column assembly 61 is arranged such that after the lifting assembly 4 is adjusted to a preset height, the lower end of the support column assembly 61 is extended and abuts against the upper surface of the vehicle body 21 to provide a supporting force.

[0075] When the lifting assembly 4 adjusts the side form system 85 to the preset height, the support assembly 61 can be adjusted in height to just abut against the upper surface of the vehicle body 21, forming additional support for the support beam assembly 5. This support mode is directly aimed at the scenario where the side form system 85 bears a large load during pouring, effectively solving the problem that the lifting assembly 4 is easily damaged by long-term bearing of a large load: the core function of the lifting assembly 4 is to realize flexible adjustment of the height of the side form system 85, and its structural design focuses more on adjustment accuracy than long-term load bearing capacity. The support assembly 61, by cooperating with the support beam assembly 5 and the vehicle body 21, transfers the load during pouring from the lifting assembly 4 to itself, greatly reducing the load pressure on the lifting assembly 4, reducing component wear or functional failure of the lifting assembly 4 due to overload, and prolonging the service life of the lifting assembly 4. As shown in FIG. 25B, this is the state where the support assembly 61 has not yet abutted against the upper surface of the vehicle body 21. Figure 3

[0076] At the same time, the support function of the support assembly 61 can also avoid the problem of decreased adjustment accuracy of the lifting assembly 4 after bearing a large load. The accuracy of the lifting assembly 4 depends on the stable cooperation of the internal transmission structure (such as lead screws, oil cylinders, etc.). If it bears a load that exceeds the design range for a long time, it is easy to cause the internal transmission gap to increase or the components to deform, thereby affecting the accuracy of subsequent height adjustment. The timely intervention of the support assembly 61 in supporting the side form system 85 after reaching the preset height allows the lifting assembly 4 to not need to continuously bear the load during pouring, maintains the stable state of its internal transmission structure, ensures that it can still maintain high accuracy during subsequent height adjustment of the side form system 85, guarantees the consistency of the position of the side form system 85 in different construction stages, and reduces construction rework caused by accuracy deviation.

[0077] The design of the lower end of the support assembly 61 abutting against the upper surface of the vehicle body 21 also optimizes the stress and load transfer path of the entire system. The vehicle body 21, as the core load-bearing structure of the trolley assembly 2, has much better structural strength and stability than the movable sliding block 3 - the core function of the sliding block 3 is to realize sliding adjustment of the side form system 85 along the width direction of the beam body 81, and its cooperation with the trolley assembly 2 focuses more on flexibility than load bearing. The support assembly 61 directly transfers the load to the vehicle body 21, allowing the load to be dispersed to the walking wheels 22 and the track assembly 1 through the main structure of the vehicle body 21, forming a stable transfer path of "side form system 85-support beam assembly 5-support assembly 61-vehicle body 21-track assembly 1", avoiding the concentration of load on the sliding block 3 or the lifting assembly 4, reducing the local structural overload caused by unreasonable stress path, further improving the structural stability of the entire side form running and mold adjusting system during construction, reducing the shaking or displacement of the side form system 85 during pouring, and ensuring the dimensional accuracy of the beam body 81 after pouring and forming, thereby improving the quality of bridge construction.

[0078] ​Meanwhile, the height-adjustable feature of the support column assembly 61 makes it have good adaptability. No matter what preset height the lifting assembly 4 adjusts the side mold system 85 to, the support column assembly 61 can effectively support through its own height adjustment, without the need to design a separate support structure for different height requirements, and without affecting the height adjustment of the lifting assembly 4 on the support beam assembly 5, and without interference, thereby enhancing the adaptability of the entire system to different construction scenes.

[0079] According to one embodiment of the present application, as shown in Figure 2 The support beam assembly 5 further includes a first mounting seat 51, and the upper end of the support column assembly 61 is connected with the first mounting seat 51; and a second mounting seat 52, and the upper end of the lifting assembly 4 is connected with the second mounting seat 52.

[0080] The first mounting seat 51 serves as a connecting medium of the support column assembly 61 and the support beam assembly 5, effectively solving the problem that the support column assembly 61 is difficult to be directly connected with various beam bodies in the support beam assembly 5. The beam body structure in the support beam assembly 5 can be designed into different cross-sectional forms or materials due to functional requirements. If the support column assembly 61 is directly connected with these beam bodies, the connection interface is likely to be mismatched, and the force transmission is likely to be uneven. The first mounting seat 51 can be adaptively designed according to the connection end structure of the support column assembly 61 and the surface form of the beam body in the support beam assembly 5, to form a stable transition connection structure, so as to ensure that the upper end of the support column assembly 61 can be firmly connected to the support beam assembly 5, thereby ensuring the force transmission reliability of the support column assembly 61 in the supporting stage, avoiding the failure of the support force of the support column assembly 61 due to unstable connection, and affecting the structural stability of the side mold system 85 during pouring. The second mounting seat 52 is similar, and will not be described herein.

[0081] The first mounting seat 51 and the second mounting seat 52 together form a standardized mounting base, further improving the assembly efficiency and maintenance convenience of the entire side mold running and mold adjusting system. During system assembly, there is no need to perform on-site adaptive processing for each connection of the support column assembly 61, the lifting assembly 4 and the support beam assembly 5. Instead, the first mounting seat 51 and the second mounting seat 52 manufactured in advance are only needed to be docked, so that the assembly can be quickly completed, reducing the adjustment time of on-site construction. Moreover, the arrangement of the two mounting seats can also optimize the force transmission path, so that the support force of the support column assembly 61 and the adjusting force of the lifting assembly 4 are uniformly dispersed to the beam body of the support beam assembly 5 through the mounting seats, avoiding local stress concentration to cause the beam body in the support beam assembly 5 to deform, thereby prolonging the service life of the support beam assembly 5.

[0082] According to one embodiment of the present application, as shown in Figure 7 The side mold running and mold adjusting system of the bridge building machine further includes a driving unit 62; see Figure 2The vehicle body 21 is provided with a horizontal sliding hole 211, the opening of the sliding hole 211 is formed on the side surface of the vehicle body 21, the sliding block 3 is installed in the sliding hole 211 and extends out of the sliding hole 211 at both ends to install the lifting assembly 4, and the driving unit 62 is installed in the sliding hole 211 and drives the sliding block 3 to slide. Alternatively, the vehicle body 21 is provided with a horizontal sliding hole 211, the sliding block 3 is installed in the sliding hole 211 and extends out of the sliding hole 211 at both ends to install the lifting assembly 4, and the driving unit 62 is installed in the sliding hole 211 and drives the sliding block 3 to slide; the sliding blocks 3 are arranged at least two in the advancing direction of the vehicle body 21, and the adjacent two sliding blocks 3 are connected by a connecting rod to slide synchronously (not shown in the figure).

[0083] The driving unit 62 can be an oil cylinder. The driving unit 62 is installed in the sliding hole 211, which can make full use of the internal space of the sliding hole 211 on the side surface of the vehicle body 21, avoid occupying the external space of the vehicle body 21, reduce the space occupancy rate of the whole system, and is especially suitable for scenes with limited space in the construction of the beam body 81.

[0084] On this basis, a connecting rod can be further arranged to connect the front and rear sliding blocks in the advancing direction, so that the front and rear sliding blocks move synchronously to the left or to the right, and the stable movement of the supporting beam assembly 5 installed on the two sliding blocks is ensured. The presence of the connecting rod avoids the situation that the two sliding blocks drive the same supporting beam assembly 5 to jam or be out of coordination.

[0085] According to one embodiment of the present application, as shown in Figure 8 , the track assembly 1 is provided with a reverse jacking wheel 13 at the rear end portion in the length direction of the beam body 81, which abuts against the lower surface of the wing plate 812 of the beam body 81 to limit the lifting of the rear end of the main truss system 7 of the bridge machine.

[0086] As shown in Figure 8 and Figure 10 , the reverse jacking wheel 13 is arranged at the rear end portion of the track assembly 1 in the length direction of the beam body 81, and forms a reverse support structure by abutting against the lower surface of the wing plate 812 of the beam body 81, which plays a role in solving the problem that the rear end of the main truss system 7 is prone to lifting during the operation of the bridge machine. When the bridge machine is moving the side form system 85 and pouring concrete, the front end of the main truss system 7 often bears the combined load of the side form system 85, the supporting beam assembly 5 and the construction materials, which easily leads to the imbalance trend that the front end of the main truss system 7 sinks and the rear end of the main truss system 7 rises. The reverse jacking wheel 13 effectively limits the lifting of the rear end of the main truss system 7 by contacting the lower surface of the wing plate 812 of the beam body 81, maintains the horizontal posture of the main truss system 7 as a whole, and reduces the risk of structural damage or safety accidents caused by load imbalance.

[0087] The anti-top wheel 13 is installed based on the track assembly 1. There is no need to open up a complicated installation structure on the beam 81 or the main truss system 7. It can be arranged by simply using the existing space at the rear end of the track assembly 1, avoiding damage to the structural integrity of the beam 81. At the same time, it does not interfere with the normal movement of the trolley assembly 2 on the track assembly 1, ensuring that the adjustment of the side formwork system 85 along the length of the beam 81 is not affected.

[0088] The rear-end constraint structure formed by the anti-jacking wheel 13 compensates for the shortcomings of existing bridge-building machines in load balance design. Compared to relying on the strength of the main truss system 7 itself to resist rear-end lifting, the anti-jacking wheel 13 directly disperses the force on the rear end of the main truss system 7 through external support, reducing stress concentration in the main truss system 7 and extending its service life. At the same time, the supporting effect of the anti-jacking wheel 13 is immediate. Regardless of how the load at the front end of the main truss system 7 changes, as long as there is a lifting trend at the rear end, the anti-jacking wheel 13 can quickly make contact with the lower surface of the wing plate 812 and provide support, avoiding the support lag problem caused by load fluctuations and providing stable protection for the safety of equipment and personnel during construction.

[0089] In some cases, limiting devices may be installed at the front and rear ends of the track assembly 1 to prevent the trolley assembly 2 from sliding off the track assembly 1.

[0090] A bridge-building machine according to a second aspect embodiment of this application, such as Figure 12 As shown, the bridge-building machine includes: a main truss system 7, including a crossbeam assembly 71, which extends along the width direction of the beam body 81; the main body of the crossbeam assembly 71 is located above the beam body 81, and the end of the crossbeam assembly 71 in the length direction bends along the flange 812 of the beam body 81 and extends to below the flange 812 of the beam body 81 to form a C-shaped limiting end 714; the aforementioned side formwork traveling and adjusting system of the bridge-building machine, wherein the track assembly 1 of the side formwork traveling and adjusting system of the bridge-building machine is installed on the limiting end 714.

[0091] like Figure 12 As shown, the crossbeam assembly 71 of the main truss system 7 extends along the width direction of the beam 81, with its main body located above the beam 81, providing a stable top support foundation for the entire bridge-building machine. The end of the crossbeam assembly 71 in the length direction bends along the flange 812 of the beam 81 and extends below the flange 812, forming a C-shaped limiting end 714. This structural design effectively solves the limitation that the end of the traditional main truss can only cover the top of the beam 81 and cannot extend to the bottom of the flange 812. This allows the support range of the crossbeam assembly 71 to cover both the top of the beam 81 and the bottom of the flange 812, forming a wrapping support trend for the beam 81. This improves the structural compatibility between the main truss system 7 and the beam 81 and reduces the risk of the main truss system 7 shifting outwards from the flange 812 during construction.

[0092] The track assembly 1 of the side mold running and mold adjusting system of the bridge builder is installed on the C-shaped limiting end 714, so that the track assembly 1 obtains a stable installation position close to the outer side of the wing plate 812, avoiding the problem of too long force transmission path caused by the installation base of the traditional track assembly 1 being far away from the operation area of the side mold system 85. The C-shaped limiting end 714 can directly provide rigid support for the track assembly 1, reducing the shaking of the track assembly 1 when the trolley assembly 2 moves or the side mold system 85 is loaded, thereby improving the position adjustment accuracy of the side mold running and mold adjusting system, and ensuring that the side mold system 85 remains stable when moving along the length direction of the beam body 81 or adjusting in the width direction perpendicular to the beam body 81.

[0093] In addition to the above structure, the bridge builder can also include other structures, and the following exemplary describes part of the structure of the bridge builder: As shown in Figure 12 The top-supported bridge builder includes: a main truss system 7 including a main rod assembly 72 extending along the length direction of the beam body 81, and a cross beam assembly 71 extending along the direction perpendicular to the length direction of the main rod assembly 72; the main body part of the cross beam assembly 71 is located above the beam body 81, the edge of the cross beam assembly 71 is bent along the wing plate 812 of the beam body 81 and extends to the limiting end 714 below the beam body 81, and the limiting end 714 cooperates with the lower surface of the wing plate 812 to limit the separation of the main truss system 7 from the beam body 81; the main rod assembly 72 is located above the beam body 81, and the main rod assembly 72 and the cross beam assembly 71 are fixedly connected; a running system is installed below the main rod assembly 72 and used to abut against the beam body 81. The main rod assembly 72 includes a first main rod 721 and a second main rod 722 arranged at intervals in the width direction of the beam body 81; the cross beam assembly 71 includes a first cross beam 711 and a second cross beam 712 arranged at intervals in the length direction of the beam body 81; the main rod assembly 72 is arranged between the cross beam assembly 71 and the beam body 81.

[0094] The top-supported bridge builder in the embodiment of the present application forms a truss structure of the main truss system 7 through the main rod assembly 72 and the cross beam assembly 71, the edge of the cross beam assembly 71 is bent along the wing plate 812 of the beam body 81 and extends to the limiting end 714 below the beam body 81, the limiting end 714 cooperates with the lower surface of the wing plate 812 to build a limiting constraint between the main truss system 7 and the beam body 81, effectively limiting the separation of the main truss system 7 from the beam body 81, avoiding the risk of front overturning of the main truss system 7 due to the front end being loaded, and significantly improving the overall stability of the main truss system 7. The cooperation mode between the limiting end 714 and the lower surface of the wing plate 812 can be that the limiting end 714 directly abuts against the lower surface of the wing plate 812, or further setting a reverse jacking wheel 13 on the limiting end 714 to abut against the lower surface of the wing plate 812 (that is, the reverse jacking wheel 13 can be arranged on the C-shaped limiting end 714, or on the rear end of the track assembly 1), or setting a connecting structure between the limiting end 714 and the lower surface of the wing plate 812 for fixation.

[0095] The top-supported bridge building machine in the embodiment of the present application can break through the length limitation of the existing hanging basket in pouring, can be applied to bridge pouring of segments of more than 6 meters, reduces the construction period loss caused by complex structures, improves the bridge pouring efficiency, solves the problems of large weight, difficult linear control and inconvenient operation of the traditional hanging basket with a novel structure, and has strong practicality and technical advantages. In the top-supported bridge building machine in the embodiment of the present application, the main truss system 7 is arranged above the beam body 81, and the limiting end 714 formed by the edge bending of the cross beam assembly 71 directly or indirectly abuts against the lower surface of the wing plate 812. Compared with the structure of the top-supported type depending on the support below the beam body 81, the problem of insufficient overturning moment caused by the support point below the beam body 81 is avoided, especially when the front end is loaded, the limiting end 714 and the walking system form a cooperative constraint mechanism, and the anti-tilting stability is significantly improved. The main truss system 7 of the top-supported bridge building machine is located above the beam body 81, and the space below the beam body 81 is completely open, without occupying the operation area below the bridge. Compared with the form of the top-supported type needing to arrange a support structure below the beam body 81, it is more suitable for construction in complex terrains such as river channels and gorges, avoids the influence of the support below on navigation and road traffic, at the same time provides an unobstructed operation space for the concrete pouring and prestress tensioning process of the bottom surface of the beam body 81, and improves the construction convenience. The main rod assembly 72 and the cross beam assembly 71 of the top-supported bridge building machine form a truss structure, and the bearing rod is concentrated above the beam body 81, without the need to set a complex support frame below the beam body 81 like the top-supported hanging basket, reducing the structural redundancy and the overall weight. The design of the limiting end 714 directly acting on the lower surface of the wing plate 812 omits the bottom anchoring system or counterweight structure required by the top-supported type, makes the beam surface structure simpler, greatly reduces the reserved holes and embedded parts on the beam surface, and simplifies the structure while enhancing the reliability.

[0096] According to an embodiment of the present application, along the length direction of the beam body 81, the cross beam assembly 71 includes three cross beam rods arranged at intervals.

[0097] The number of three can be adapted to the length of the beam body 81 and the demand of the construction scene: the interval arrangement of the three cross beam rods can improve the support strength.

[0098] According to an embodiment of the present application, based on the cross beam assembly 71 including three cross beam rods arranged at intervals, along the height direction of the beam body 81, the track assembly 1 includes a single-layer beam, as shown in Figure 11 .

[0099] When the three cross beam rods are arranged at intervals along the length direction of the beam body 81, the cross beam assembly 71 forms multiple-point support along the length direction of the beam body 81, the support points are uniformly distributed and have moderate density, and the track assembly 1 can be provided with a stable bearing foundation, so that the track assembly 1 can meet the bearing requirement by using a single-layer beam. Such adaptive design simplifies the overall structure of the track assembly 1, reduces the material usage and processing procedures, and reduces the load pressure of the main truss system 7, avoids the force imbalance of the main truss system 7 caused by the excessive weight of the track assembly 1, and ensures the structural stability of the main truss system 7. The single-layer beam structure is simple, shortens the installation period of the track assembly 1, is convenient for maintenance operation, and can maintain the smoothness of the movement of the trolley assembly 2 along the track assembly 1.

[0100] According to one embodiment of the present application, as shown in Figure 10 and Figure 12 Based on the cross beam assembly 71 including three cross beam rods arranged at intervals, the three cross beam rods are respectively the first cross beam 711, the second cross beam 712 and the third cross beam 713, the first cross beam 711 is located at the front end of the length direction of the beam body 81, the third cross beam 713 is located at the rear end of the length direction of the beam body 81, and the second cross beam 712 is located between the first cross beam 711 and the third cross beam 713; the bottom of the third cross beam 713 is provided with a connecting seat 7131, and the connecting seat 7131 and the bottom of the second cross beam 712 are connected through the first support rod 715.

[0101] The first cross beam 711, the second cross beam 712 and the third cross beam 713 are arranged at intervals along the length direction of the beam body 81, the first cross beam 711 is located at the front end, the third cross beam 713 is located at the rear end, and the second cross beam 712 is located between the two, such a distribution forms a multiple-point support foundation of the cross beam assembly 71 along the length direction of the beam body 81, can disperse the load transmitted by the track assembly 1 to different positions, and avoids the force concentration of a single cross beam rod. The connecting seat 7131 provided at the bottom of the third cross beam 713 provides a stable connecting carrier for the first support rod 715, and the first support rod 715 connects the connecting seat 7131 and the bottom of the second cross beam 712, which is equivalent to building a bridging support structure between the second cross beam 712 and the third cross beam 713, and directly strengthens the rigidity of the connection position of the third cross beam 713 and the rear end of the track assembly 1.

[0102] The rear end of the track assembly 1 is mounted on the third cross beam 713. During construction, the front end of the main truss system 7 is relatively heavy, which causes the rear end of the track assembly 1 to have a tendency to lift upward. The first support rod 715 forms a downward constraint on the third cross beam 713 through the supporting force of the second cross beam 712, thereby limiting the upward lifting of the third cross beam 713 and preventing the rear end of the track assembly 1 from lifting with the deformation of the third cross beam 713, thereby ensuring the flatness of the track assembly 1 as a whole. The flatness of the track assembly 1 is stable, which can ensure the accuracy of the track of the trolley assembly 2 when moving along the track assembly 1, avoid the trolley assembly 2 from being stuck or deviated due to the deformation of the track, further ensure the accuracy of the position adjustment of the side mold system 85 along the length direction of the beam body 81, reduce the position deviation of the side mold system 85 caused by the deformation of the rear end of the track, and reduce the construction risk.

[0103] The first support rod 715 builds a load transmission path between the second cross beam 712 and the third cross beam 713, so that part of the load borne by the third cross beam 713 is transmitted to the second cross beam 712 through the first support rod 715, so that the second cross beam 712 participates in load sharing, changes the condition that only the third cross beam 713 bears the load of the rear end of the track assembly 1, and optimizes the stress distribution of the whole cross beam assembly 71. This load sharing mode can reduce the local stress of the third cross beam 713, avoid structural damage of the third cross beam 713 due to long-term bearing of concentrated load, prolong the service life of the third cross beam 713, and at the same time improve the bearing stability of the whole cross beam assembly 71, thereby providing support for the safe operation of the main truss system 7 of the bridge building machine.

[0104] According to one embodiment of the present application, as shown in Figure 10 When the rear end of the track assembly 1 is located behind the third cross beam 713, the second support rod 716 is connected between the connecting seat 7131 and the rear end of the track assembly 1.

[0105] As shown in Figure 8 When the size of the 0th block is small, a single first support rod 715 is used for strengthening connection, which can ensure the rigidity of the cross beam assembly 71 and avoid interference.

[0106] As shown in Figure 10As shown, when the rear end of the track assembly 1 is located behind the third cross beam 713, the third cross beam 713 cannot directly support the rear end of the track assembly 1, and the rear end of the track assembly 1 is prone to cantilever structure due to lack of support, and is prone to upward deformation, affecting the smoothness of the trolley assembly 2 movement and the stability of the side mold system 85 position. The second support rod 716 is connected between the connecting seat 7131 and the rear end of the track assembly 1, which can provide targeted support for the rear end of the track assembly 1, fill the support gap behind the third cross beam 713, form a force transmission path from the connecting seat 7131 (fixedly connected to the bottom of the third cross beam 713) to the rear end of the track assembly 1, effectively prevent excessive deformation of the rear end of the track assembly 1 due to lack of support, and guarantee the flatness of the track assembly 1 as a whole, ensure that the trolley assembly 2 always maintains a stable trajectory when moving along the entire length of the track assembly 1, and avoid trolley jamming or position deviation of the side mold system 85 due to track deformation.

[0107] At the same time, the second support rod 716 can share the load borne by the rear end of the track assembly 1, and transmit part of the load of the rear end of the track assembly 1 to the connecting seat 7131 through the second support rod 716, and then transmit the load to the third cross beam 713 through the connecting seat 7131, avoiding the track assembly 1 relying only on its own structure to transmit the load at the rear end to the connecting position with the third cross beam 713, and reducing stress concentration at the connecting position of the track assembly 1 and the third cross beam 713. This load dispersion can protect the connecting structure of the track assembly 1 and the third cross beam 713, avoid connection loosening or structure damage caused by long-term stress concentration, prolong the service life of the track assembly 1 and the cross beam assembly 71, and reduce the construction safety risk caused by the failure of the connecting position.

[0108] Furthermore, the second support rod 716 and the first support rod 715 (connecting the connecting seat 7131 and the bottom of the second cross beam 712) can form a cooperative support system. The first support rod 715 strengthens the rigidity of the connecting position of the third cross beam 713 and the rear end of the track assembly 1, and the second support rod 716 focuses on the support of the part of the track assembly 1 beyond the third cross beam 713. Both of them act together from the two dimensions of “connection position rigidity strengthening” and “extended end support supplementing”, further improve the structural stability and anti-deformation ability of the track assembly 1 as a whole, so that the track assembly 1 can still adapt to the normal operation of the side mold running and mold adjusting system even in the case of rear end extension, and ensure the reliability of the bridge building machine in different construction conditions (such as the track assembly 1 needs to be extended to cover a wider construction range).

[0109] As shown in the drawings, Figure 21As shown, according to the bridge manufacturing method of the third aspect of the present application, the bridge manufacturing method uses the aforementioned bridge building machine, and the bridge manufacturing method comprises: performing first pouring at an initial position; retreating the side mold system 85 and the bottom basket system 84 to the rear end of the main truss system 7; driving the main truss system 7 to advance to a second pouring position by the walking system; driving the side mold system 85 and the bottom basket system 84 to advance to the front end of the main truss system 7; adjusting the position of the side mold system 85 by the side mold walking and mold adjusting system of the bridge building machine; and performing second pouring. Then, the above steps are cycled to realize segmental pouring of the beam body 81.

[0110] The first pouring is completed at the initial position, which builds a basic segment for the bridge structure and ensures that the beam body 81 poured subsequently has a stable reference when connected to the initial structure, thereby avoiding problems such as structural misalignment and insufficient strength caused by the absence or instability of the initial structure.

[0111] After the first pouring is completed at the initial position, the side mold system 85 and the bottom basket system 84 are retreated to the rear end of the main truss system 7. This operation can directly adjust the overall weight distribution of the bridge building machine. By reducing the load weight at the front end of the main truss system 7 and increasing the weight at the rear end of the main truss system 7, the center of gravity of the main truss system 7 is optimized, which effectively avoids the front tilting of the main truss system 7 due to the forward center of gravity during subsequent advancement, thereby providing a key guarantee for the structural safety and stable operation of the bridge building machine.

[0112] The walking system drives the main truss system 7 to advance to the second pouring position. Through the power output and guiding effect of the walking system, the moving track of the main truss system 7 is ensured to be accurate, so that the main truss system 7 can accurately dock the extension position of the beam body 81 required for the second pouring, thereby providing a reliable position reference for the subsequent resetting of the side mold system 85 and the bottom basket system 84.

[0113] After the side mold system 85 and the bottom basket system 84 are driven to the front end of the main truss system 7, the side mold system 85 forms a closed and stable pouring space, which meets the requirements of mold support and structural sealing for the second pouring, and ensures that the concrete poured in the second pouring can be formed in the preset space and seamlessly connected to the beam body 81 poured in the initial pouring, thereby improving the overall structural strength and quality of the bridge.

[0114] The whole method realizes an orderly cycle of “pouring-component retreat-main truss movement-component resetting-pouring again”, which not only solves the safety hazard of the front tilting of the main truss system 7, but also guarantees the construction accuracy and process continuity, adapts to the construction requirements of segmental pouring of the bridge, reduces the additional damage to the main truss system 7, and prolongs the service life of the bridge building machine.

[0115] According to an embodiment of the present application, the adjustment of the position of the side mold system 85 by the side mold walking and mold adjusting system of the bridge building machine comprises: adjusting the front and rear positions of the side mold system 85 by moving the trolley assembly 2; Adjust the left and right positions of the side mold system 85 using slider 3; The vertical position of the side mold system 85 is adjusted by the lifting component 4.

[0116] According to one embodiment of this application, after adjusting the front-rear position of the side mold system 85 by moving the trolley assembly 2, the method further includes: After the side mold system 85 is adjusted to the preset position, the locking mechanism is activated to restrict the movement of the trolley assembly 2. In practical applications, the left and right movement of the slider 3 and the up and down extension and retraction of the lifting assembly 4 can also be locked.

[0117] According to one embodiment of this application, before the second pouring, the method further includes: The strut assembly 61 extends to abut against the upper surface of the vehicle body 21 to provide support.

[0118] According to one embodiment of this application, after the second pouring, the method further includes: The strut assembly 61 shortens and separates from the upper surface of the vehicle body 21. Of course, the aforementioned locking mechanism should also be released to avoid affecting the next forward movement of the main truss system 7.

[0119] According to one embodiment of this application, before the side formwork system 85 and the bottom basket system 84 retract to the rear end of the main truss system 7, the method further includes: the anti-top wheel 13 on the track assembly 1 abutting against the bridge flange (i.e., the wing plate 812); after the side formwork system 85 and the bottom basket system 84 advance to the front end of the main truss system 7, the method further includes: the anti-top wheel 13 on the track assembly 1 separating from the bridge flange.

[0120] According to one embodiment of this application, before the side formwork system 85 and the bottom basket system 84 advance to the front end of the main truss system 7, the method further includes: fixing the main truss system 7 to the already poured beam segment through the anchoring device 82; before the traveling system drives the main truss system 7 to advance to the second pouring position, the method further includes: releasing the fixing connection of the anchoring device 82.

[0121] The pouring state of the upper-bearing bridge-building machine provided in this application embodiment is as follows: Figure 13 As shown; at this time, the left side of the figure is the already poured part 86 of the beam, and the right side is the part of the beam to be poured 87 (that is, not yet poured).

[0122] During travel, the hydraulic cylinder cooperating with the anti-jacking wheel 13 extends, causing the anti-jacking wheel 13 to press against the bridge flange (lower surface of the flange 812). The drive device then retracts the side formwork system 85 and the bottom basket system 84 along the track assembly 1 to a position similar to... Figure 14 The position is shown to reduce the front-end load of the main truss system 7 during travel. Then, the connection between the anchoring device 82 and the already cast portion 86 of the beam is released, and the main truss system 7 is moved forward using the drive device to the position shown. Figure 15The anchor device 82 is fixedly connected with the beam body casted part 86. Finally, the side mold system 85 and the bottom basket system 84 are moved along the track assembly 1 to the position shown in FIG. 8, and the walking is completed. The reverse jacking wheel 13 at the rear end of the track assembly 1 is separated from the bridge wing, and the pouring is prepared. Figure 16 Since the walking is completed, the beam body 81 in the figure is the beam body casted part 86, and the beam body to be casted part 87 is not shown. Figures 14 to 16 Since the walking is completed, the beam body 81 in the figure is the beam body casted part 86, and the beam body to be casted part 87 is not shown.
