[0022] The present application will be further described in detail below with reference to the drawings.

[0023] The embodiment of the application discloses a wisdom bridge building machine synchronous walking power system, please refer to Figures 1-6 , including setting up on the bridge deck of the already poured segment truss 10, wherein the truss 10 includes track 11, mobile base 12, support frame. Specifically, the track 11 is provided with two and is parallelly arranged on the already poured bridge deck, the track 11 extends along the length direction of the bridge and is provided with positioning groove 111. The mobile base 12 is symmetrically arranged on the two tracks 11, and the mobile base 12 is slidingly matched with the track 11, and the mobile base 12 is used for supporting and driving the support frame to move along the track 11. The support frame contains the gantry 13 crossing the bridge, the bottom of which is fixedly connected with the mobile base 12, and the both side columns are provided with cantilever main beams 131 at the ends. A forming formwork 20 is also provided, wherein the forming formwork 20 is symmetrically connected to the both side main beams 131 and is fixed with the ground foundation, and is used for pouring the bridge segment.

[0024] Wherein the top of the gantry 13 is provided with at least two cross bars 132, and each cross bar 132 is provided with a first direction driving mechanism 30, and the first direction driving mechanism 30 contains: The vertical hydraulic cylinder 31 is arranged on the cross bar 132, and the piston rod end thereof is hingedly connected with the guide connecting rod 311; the four-bar linkage mechanism 32 is hingedly connected with the cross bar 132 at the upper end and is hingedly connected with the horizontal hydraulic cylinder 33 at the lower end; the self-locking plug 34 is driven by the horizontal hydraulic cylinder 33 and is provided with a wedge-shaped lock tongue 35, and the slope of the wedge-shaped lock tongue 35 is inclined from bottom to top towards one side of the gantry 13; the cooperative control system is configured to control the lifting action of the two vertical hydraulic cylinders 31, and through the lever effect of the four-bar linkage mechanism 32, the horizontal hydraulic cylinder 33 is linked to make the two self-locking plugs 34 produce alternating track 11 locking and releasing action.

[0025] The above-mentioned wisdom bridge building machine synchronous walking power system is a mechanical device for realizing the accurate positioning and movement of the bridge deck formwork or the prefabricated segment in the bridge construction, especially in the segment assembled bridge. The overall movement process can be summarized as follows: Preparation stage: the truss 10 is arranged on the bridge deck which has been poured and completed, as the support foundation of the whole system. The mobile base 12 is slidingly matched with the track 11 and is symmetrically arranged on the two tracks 11, so as to ensure that the system can move smoothly along the length direction of the bridge. The gantry 13 is fixedly connected with the mobile base 12 at the bottom, forming a structure crossing the bridge, and the cantilever main beams 131 at the ends of the both side columns provide support for the forming formwork 20. The forming formwork 20 is symmetrically connected to the both side main beams 131 and is fixed with the ground foundation, and is used for pouring the bridge deck or the prefabricated segment in the subsequent stage.

[0026] Locking: When the system needs to enter the locking state, the vertical hydraulic cylinder 31 starts to act. As the piston rod of the vertical hydraulic cylinder 31 extends, the action force is transmitted through the guide link 311 articulated therewith. During the descent of the self-locking plug 34, the wedge-shaped locking tongue 35 gradually embeds into the positioning groove 111 on the track 11, and through the physical obstruction, the gantry 13 is firmly locked relative to the track 11.

[0027] Moving process: After the track 11 is locked, the horizontal hydraulic cylinder 33 is driven to extend. Since the gantry 13 is fixedly connected with the moving base 12, and the moving base 12 is in sliding fit with the track 11, the gantry 13 (and the entire system) will move along the track 11.

[0028] Unlocking: When the system needs to be unlocked and stop moving, the cooperative control system first drives the vertical hydraulic cylinder 31 to retract. As the piston rod of the vertical hydraulic cylinder 31 rises, the four-bar linkage mechanism 32 acts again, driving the horizontal hydraulic cylinder 33 to move upward through the lever effect, so that the wedge-shaped locking tongue 35 is separated from the positioning groove 111 of the track 11. And the piston rod of the horizontal hydraulic cylinder 33 is retracted, so that it returns to the initial state. With the complete separation of the wedge-shaped locking tongue 35, the locking state of the track 11 is released, and the system returns to the initial state, ready for the next locking, moving or unlocking operation.

[0029] In actual application, the two first direction driving mechanisms 30 can choose synchronous motion or alternating operation mode according to specific work requirements and site conditions. The synchronous motion mode is suitable for the case where the moving speed and position need to be accurately controlled, such as in fine positioning or precise pouring construction links. The alternating operation mode is more suitable for the case where the system posture needs to be flexibly adjusted or the complex and variable working environment needs to be coped with. Through the flexible control of the cooperative control system, the two first direction driving mechanisms 30 can smoothly switch between different modes to meet various needs in the process of bridge construction.

[0030] It should be pointed out that the side of the first direction driving mechanism 30 towards the forward direction can be set, and at this time, the inclined surface of the wedge-shaped locking tongue 35 faces away from the forward direction, so that the stability of the first direction driving mechanism 30 during operation is better.

[0031] The present application is described by setting two tracks 11 as an example, and in actual use, a plurality of groups of tracks 11 can be set according to actual needs.

[0032] Please refer to Figures 1-4Further, the embodiment also includes a second direction driving mechanism 40 arranged at the other end of the cross bar 132 away from the first direction driving mechanism 30. The second direction driving mechanism 40 has the same structure as the first direction driving mechanism 30, and the wedge-shaped locking tongues 35 thereof are symmetrical with the wedge-shaped locking tongues 35 in the first direction driving mechanism 30 along the length direction of the portal frame 13. Such design can further improve the stability and synchronization of the bridge builder during walking.

[0033] By adding the second direction driving mechanism 40 and arranging it symmetrically with the first direction driving mechanism 30, the portal frame 13 achieves the ability to move bidirectionally on the track 11, further improving the flexibility and construction efficiency of the intelligent bridge builder. The second direction driving mechanism 40 has similar structure and function as the first direction driving mechanism 30, but the arrangement direction of the wedge-shaped locking tongues 35 thereof is symmetrical with the first direction driving mechanism 30, so that the portal frame 13 can not only move forward, but also move backward when needed, adapting to more complex construction scenarios.

[0034] Moreover, the second direction driving mechanism 40 uses the same self-locking plug 34 design as the first direction driving mechanism 30, and the symmetrical arrangement of the wedge-shaped locking tongues 35 ensures uniform distribution of locking force during bidirectional movement, preventing the portal frame 13 from deviating or sliding during movement. Whether advancing or retreating, the system can maintain stability through the reliable locking function of the self-locking plug 34, ensuring the safety of the construction process.

[0035] The user can use the first direction driving mechanism 30 alone to make the portal frame 13 move in the first direction. The second direction driving mechanism 40 can also be used alone to make the portal frame 13 move in the second direction. The self-locking plug 34 in the second direction driving mechanism 40 can be locked with the positioning groove 111 by driving the vertical hydraulic cylinder 31 in the second direction driving mechanism 40 based on the use of the first direction driving mechanism 30, further improving the stability of the portal frame 13 relative to the track 11.

[0036] The two first direction driving mechanisms 30 can be used synchronously or alternately. When used synchronously, the first direction driving mechanisms 30 on both sides act simultaneously to push the portal frame 13 to move forward quickly and smoothly, suitable for construction scenarios that require rapid advancement. When used alternately, the first direction driving mechanisms 30 on both sides act alternately to achieve step-by-step movement of the portal frame 13 by alternately locking and releasing the track 11, suitable for construction scenarios that require precise positioning. Such flexibility enables the system to adapt to different construction needs, improving construction efficiency.

[0037] Please refer to Figure 4When the two vertical hydraulic cylinders 31 on the same crossbar 132 are extended, the connecting rod in the first direction driving mechanism 30 and the connecting rod in the second direction driving mechanism 40 form a first included angle a in the range of 60°-120°, so as to adapt to the walking requirements in different working conditions. The first included angle a can be selected as 60°, 90°, 120°, and the best is 90°.

[0038] When the two vertical hydraulic cylinders 31 on the same crossbar 132 are extended, the connecting rod in the first direction driving mechanism 30 and the connecting rod in the second direction driving mechanism 40 form a first included angle a in the range of 60°-120°, so as to adapt to the walking requirements in different working conditions. The first included angle a can be selected as 60°, 90°, 120°, and the best is 90°.

[0039] If the first angle is 90°, the formation of the equilateral triangle structure greatly enhances the stability of the system. Triangle is a very stable geometric shape in mechanics, which can effectively disperse and bear external load, reduce structural deformation and vibration. This stability makes the gantry 13 better resist wind load, equipment vibration or other external interference during construction, ensuring the precision and safety of construction.

[0040] If the first direction driving mechanism 30 and the second driving mechanism on both sides are accurately controlled, the gantry 13 can be slightly moved upward relative to the track 11, so that there is a gap between the moving base 12 and the track 11, and there is a gap between the forming formwork 20 and the ground, further reducing the movement of the gantry 13 affected by the moving base 12.

[0041] Please refer to Figures 1-5 The bottom of the self-locking plug 34 is provided with a receiving cavity 341, the inner top surface of the receiving cavity 341 is fixedly connected with a longitudinally arranged telescopic rod 342, and the bottom of the telescopic rod 342 is provided with a bottom plate 343; a plurality of wedge-shaped lock lugs 35 are arranged on the bottom of the bottom plate 343, and a elastic element 344 is arranged between the inner top wall of the receiving cavity 341 and the bottom plate 343.

[0042] Since the inclined surface of the wedge-shaped lock lug 35 faces the side of the gantry 13, that is, its vertical surface faces the advancing direction, and the inclined surface faces the opposite side of the advancing direction. In the state that the vertical hydraulic cylinder 31 remains stationary, the horizontal hydraulic cylinder 33 can still be independently driven. When the horizontal hydraulic cylinder 33 is retracted, the wedge-shaped lock lug 35 will move to above the next positioning groove 111 and be ejected under the elastic force of the elastic element 344; then, the horizontal hydraulic cylinder 33 is extended again, that is, the gantry 13 is pushed to move relative to the track 11.

[0043] The wedge-shaped locking tongues 35 are arranged at equal intervals along the length of the base plate 343, and the interval matches the interval of the positioning grooves 111 on the track 11. Through the interval matching design, it is ensured that each wedge-shaped locking tongue 35 can accurately correspond to the positioning groove 111, and the multi-point positioning effectively disperses the load, improves the positioning stability of the system, and reduces the influence of single-point positioning error on the overall accuracy. The distributed bearing formed by the multi-locking tongue structure can improve the overall bearing capacity of the system.

[0044] The inclination angle β of the wedge-shaped locking tongue 35 is 30°-60°, so as to adapt to tracks 11 of different hardness and material. The inclination angle of 30°-60° can provide moderate locking force when the wedge-shaped locking tongue 35 contacts the positioning groove 111, which not only ensures that the wedge-shaped locking tongue 35 can be smoothly inserted into the positioning groove 111 and achieve reliable locking, but also avoids the insufficient locking force caused by too large inclination angle or the difficulty of insertion caused by too small inclination angle. Secondly, this angle range makes the wedge-shaped locking tongue 35 be able to realize smooth retraction through the inclined surface effect when subjected to the thrust of the track 11, reduces mechanical wear and impact force, and improves the durability and operation stability of the equipment.

[0045] Please refer to Figures 4-5 When the vertical hydraulic cylinder 31 in the first direction driving mechanism 30 is extended, the connecting rod in the first direction driving mechanism 30 has a second included angle γ with the horizontal plane, and the inclination angle β of the wedge-shaped locking tongue 35 is equal to the second included angle γ, so that the self-locking plug 34 has better locking or releasing effect on the track 11.

[0046] This consistency optimizes the force transmission path, so that the vertical movement of the vertical hydraulic cylinder 31 can be more efficiently converted into the horizontal movement of the horizontal hydraulic cylinder 33, reducing energy loss and improving the motion efficiency and response speed of the system. Secondly, the consistency of the inclination angle ensures that the contact between the wedge-shaped locking tongue 35 and the track 11 is more stable during locking and releasing, avoiding mechanical interference or jamming phenomenon caused by angle mismatch, enhancing the operation stability and reliability of the system. In addition, this design also simplifies the stress analysis of the structure, so that the force transmission between the wedge-shaped locking tongue 35 and the connecting rod is more uniform, reducing local stress concentration and prolonging the service life of the equipment.

[0047] Please refer to Figures 3-6The connecting rod in the four-bar linkage mechanism 32 is provided with a sliding opening 321 extending along its length direction; the two cross bars 132 are provided with a locking assembly 50, the locking assembly 50 comprises two fixed bases 51, the two fixed bases 51 are symmetrically arranged on the adjacent two cross bars 132, a guide rod 52 and an adjusting screw rod 53 are arranged between the two fixed bases 51, the guide rod 52 is slidably sleeved with two sliding plates 54, the adjusting screw rod 53 is threadedly connected on the two sliding plates 54, the opposite side walls of the two sliding plates 54 are both provided with a limiting block configured to be inserted into the sliding opening 321 of the four-bar linkage mechanism 32 when the self-locking plug 34 is locked; one of the fixed bases 51 is provided with a motor for driving the adjusting screw rod 53 to rotate.

[0048] The limiting block in the locking assembly 50 is inserted into the sliding opening 321 of the four-bar linkage mechanism 32 when the self-locking plug 34 is locked, which can effectively limit the movement range of the connecting rod and reduce the shaking or deviation of the gantry 13 caused by external load or vibration during construction. This design significantly enhances the overall stability of the system, ensuring construction accuracy and safety. Moreover, the mechanical locking function of the locking assembly 50 reduces the dependence on the control system, simplifying the control logic. The insertion and withdrawal of the limiting block can be achieved through simple mechanical actions without the need for complex sensors or control algorithms, improving the reliability and maintenance convenience of the system.

[0049] The implementation principle of the smart bridge building machine synchronous walking power system according to an embodiment of the present application is a mechanical control concept of multiple mechanisms cooperating, which realizes precise synchronous walking function through the organic combination of hydraulic drive and mechanical linkage. The system can realize movement in a certain direction by separately controlling the first direction driving mechanism 30 or the second direction driving mechanism 40, and the vertical hydraulic cylinder and the horizontal hydraulic cylinder 33 realize continuous action of locking and releasing, ensuring that the system can move smoothly and continuously forward. This alternating working mechanism effectively avoids impact and vibration during movement, improving walking stability.

[0050] To ensure the reliability of the system, the system adopts multiple redundant protection design. The first direction driving mechanism and the second direction driving mechanism are functionally backed up, so that when one of the driving mechanisms fails, the other driving mechanism can still maintain the basic function of the system. At the same time, the distributed arrangement of multiple wedge-shaped locking tongues also forms redundant protection, and the failure of a single locking tongue will not affect the realization of the overall function. This redundant design greatly improves the safety and reliability of the system, which can effectively deal with various unexpected situations during construction.

[0051] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
