[0002] In traditional bridge construction, the demoulding and pouring processes often rely on manual operation, which presents a series of technical problems. First, manual demoulding is not only inefficient, but also easily causes damage to the concrete surface due to inconsistencies in force and angle control, affecting the appearance and quality of the bridge. Secondly, manual operation poses a safety hazard when removing the formwork, especially in high-altitude operations, where workers face a high safety risk. In addition, due to the limitations of manual operation, the lifting and vibration demoulding of the formwork are difficult to achieve uniformity and synchronization, resulting in poor demoulding effects and may even cause damage to the formwork.

[0017] The present invention proposes a method for a fully automatic demoulding mechanism of a positioning bridge-building machine.

The bridge-building machine 3 walks horizontally on the surface of the bridge body 2 to perform bridge-building operations. The bridge-building machine 3 includes side templates 4 on both sides, a supporting template 5 at the bottom, a limiting template 6 on the end face, and an internal hollow mold frame 7. The surface of the limiting template 6 is fixedly installed with the end face of the hollow mold frame 7, and the two side templates 4 are distributed on both sides of the limiting template 6, and the supporting template 5 is located at the bottom of the hollow mold frame 7.

[0036] A pouring slope adjustment mechanism 8 is provided at the bottom of the supporting formwork 5 .

[0037] In order to realize the action of automatic adjustment according to the inclination design of pouring during pouring; a pouring slope adjustment mechanism 8 is set, including an articulated seat 81 installed at the rear end of the bottom of the supporting template 5, and the two articulated seats 81 are symmetrically arranged on the surface of the supporting template 5.

The bottom mounting surfaces of the two U-shaped seats 83 are respectively fixedly installed on the top of the connecting cross bar of the bridge-building machine 3.

[0038] Specifically implemented in this way, the design of the articulated seat 81 and the U-shaped seat 83 allows the supporting formwork 5 to be flexibly adjusted according to different inclination angles to adapt to different construction requirements; the symmetrically arranged articulated seat 81 and fixed axis 82 design increases the stability of the mechanism and ensures the stability of the formwork during the pouring process; the automatic adjustment mechanism can quickly respond to changes in the pouring inclination and improve construction efficiency.

[0039] A slide rail 84 is fixedly installed on the top of the front end of the connecting cross bar of the bridge-building machine 3, and an inclined slider 85 is slidably inserted into the inner wall of the slide groove of the slide rail 84. Driving connecting rods 86 are fixedly installed on the surfaces of the three inclined sliders 85. A telescopic cylinder 87 is also hingedly installed on the top of the rear end of the connecting cross bar of the bridge-building machine 3, and the telescopic top end of the telescopic cylinder 87 is fixedly installed on the opposite surface of the middle inclined slider 85.

[0040] Specifically implemented in this way, the tilting slider 85 can be automatically moved by the drive of the telescopic cylinder 87, reducing manual operation; the three tilting sliders 85 can ensure uniform distribution of force during the adjustment process to avoid local stress concentration; the slide rail 84 provides a smooth path, and the tilting slider 85 can slide on its inner wall to achieve precise tilt adjustment; the tilting slider 85 and the telescopic cylinder 87 are connected to transmit power and realize automatic adjustment.

[0041] Vibration demoulding mechanisms 9 are provided on both sides of the two side mold plates 4 and inside the hollow mold frame 7 .

[0042] In order to realize the vibration demoulding action from front to back during demoulding; a vibration demoulding mechanism 9 is set up, including bearing seats 91, each two bearing seats 91 form a group, and the mounting surfaces of multiple groups of bearing seats 91 are all installed on the frame surface of the bridge-building machine 3, and the surfaces of each group of two bearing seats 91 are rotatably connected to a power shaft 92 through a bearing, and one end of the four power shafts 92 located inside the hollow mold frame 7 passes through and extends to the outside of the limiting template 6, and a cam 93 is fixedly installed on the surface of the power shaft 92, and multiple cams 93 are linearly arranged on the surface of the power shaft 92, and the convex points of the multiple cams 93 are distributed in a circular array with the axis center of the power shaft 92 as the center.

[0043] Specifically implemented in this way, vibration can help reduce the adhesion between concrete and the formwork, making demolding easier and faster; through the linear arrangement and circular array distribution of multiple cams 93, it can be ensured that the vibration is evenly transmitted to the entire formwork surface, avoiding local excessive or weak vibration; vibration demolding can reduce damage to the concrete surface and the formwork, maintain the integrity of the structure and the reusability of the formwork; the setting of the vibration demolding mechanism 9 makes the demolding process more automated, reduces manual operation, and reduces labor intensity.

[0044] A sleeve 94 is also fixedly installed on the frame surface of the bridge-building machine 3. The multiple sleeves 94 are grouped into five, and each group of five sleeves 94 are linearly arranged. A knocking rod 95 is slidably inserted into the inner wall of each sleeve 94, and a spring 96 is movably sleeved on the arc surface of one end of the knocking rod 95. The spring 96 is located inside the sleeve 94, and one end of the spring 96 is fixedly installed on the inner bottom wall of the sleeve 94, and the other end of the knocking rod 95 is slidably inserted into the surface of the cam 93. The knocking rod 95 is rotated by the cam 93 to control the knocking rod 95 to achieve the action of knocking vibration under the elastic force of the spring 96.

[0045] Specifically, the knocking rod 95 knocks on the formwork under the elastic force of the spring 96, which helps to break the bond between the concrete and the formwork and achieve efficient demoulding; multiple sleeves 94 are linearly arranged in groups of five to ensure the uniform distribution of vibration on the surface of the formwork and avoid local excessive or weak vibration; compared with other demoulding methods, the knocking vibration is gentler and helps to protect the formwork and concrete surface from damage; the knocking vibration can effectively reduce the demoulding time and improve construction efficiency; the rotation of the cam 93 controls the up and down movement of the knocking rod 95 through the contact between the convex points on its surface and the knocking rod 95 to achieve knocking vibration.

[0046] A linkage driving mechanism 10 is disposed at the front end of each of the plurality of vibration demoulding mechanisms 9 .

[0047] In order to realize the operation of synchronously driving multiple vibration demoulding mechanisms 9 by one power, a linkage driving mechanism 10 is set up, including a driving motor 101, which is installed on one side of a bearing seat 91, and the output end of the driving motor 101 is fixedly installed on the surface of the relative power shaft 92 through a coupling.

[0048] Specifically, it is implemented as follows: multiple vibration demoulding mechanisms 9 can be operated synchronously by one drive motor 101, thereby ensuring the consistency of the vibration action; using one drive motor 101 instead of multiple independent motors simplifies the entire drive system and reduces the complexity and cost of the equipment; reducing the number of motors, reducing the size and occupied space of the equipment, and facilitating installation and operation in a limited space; synchronous operation ensures that each demoulding mechanism can work at the same frequency and force, thereby ensuring the uniformity and quality of the concrete structure.

[0049] The front ends of the multiple power shafts 92 are fixedly installed with pulleys 102, and the inner walls of the grooves of the multiple pulleys 102 are transmission-connected with double-sided belts 103. The rotation of the power shafts 92 is controlled by driving the motor 101. When the double-sided belt 103 is synchronously engaged with the multiple pulleys 102, the synchronous rotation operation of the multiple pulleys 102 is realized.

[0050] Specifically implemented in this way, the engagement of the double-sided belt 103 with multiple pulleys 102 ensures that all power shafts 92 can rotate synchronously, thereby realizing the synchronous operation of multiple vibration demoulding mechanisms 9; the synchronously rotating power shafts 92 can perform vibration demoulding at the same time, greatly improving the demoulding efficiency; the synchronous operation ensures that the frequency and amplitude of vibration are consistent during the demoulding process, thereby ensuring the uniformity and quality of the concrete structure.

[0051] The top end and the inner side surface of the side template 4 are both provided with a demoulding and lifting mechanism 11 .

[0052] In order to realize the demoulding operation of lifting the side template 4 from front to back during demoulding, a demoulding lifting mechanism 11 is provided, including an inclined lifting plate 111, and a sliding inclined groove 112 is provided on the top and inner wall of the side template 4, and the surface of the inclined lifting plate 111 is slidably plugged into the inner wall of the sliding inclined groove 112.

[0053] Specifically implemented in this way, the lifting action of the side formwork 4 helps to break the bond between the concrete and the formwork, making the demoulding process smoother; by lifting the demoulding, the direct impact and damage to the concrete surface can be reduced, and the integrity of the concrete structure can be maintained; the cooperation between the inclined lifting plate 111 and the sliding inclined groove 112 realizes the automation of the demoulding process and reduces manual operation.

[0054] An L-shaped connecting seat 113 is also fixedly installed on the back side of the side formwork 4, a connecting shaft 114 is fixedly installed on the top of one end of the L-shaped connecting seat 113, an adapter seat 115 is rotatably connected to the arc surface of the connecting shaft 114 through a bearing, a hydraulic cylinder 116 is fixedly installed on one end of the adapter seat 115, and the telescopic end of the hydraulic cylinder 116 is fixedly installed on the opposite surface of the inclined tilting plate 111.

[0055] Specifically implemented in this way, using the hydraulic cylinder 116 as a power source can provide a strong force to drive the movement of the tilting and lifting plate 111, which is suitable for the demoulding of large or heavy-loaded formwork; the hydraulic system usually works smoothly, which helps to reduce the impact and vibration during the demoulding process and protect the concrete structure; the demoulding process is not only more efficient and automated, but also improves the safety of operation and the demoulding quality of concrete components.

[0056] Through the precise control of the linkage drive mechanism 10 and the power shaft 92, the sequential knocking vibration of the template is realized, the bonding between the side template 4 and the hollow form frame 7 and the concrete is effectively released, the smooth progress of the demoulding process is ensured, and at the same time, the damage to the concrete surface is avoided, and the surface quality of the component is improved. Secondly, the demoulding lifting mechanism 11 driven by the hydraulic cylinder 116 ensures the smooth lifting of the side template 4, further promotes the smooth completion of the demoulding operation, and improves the demoulding efficiency. Furthermore, through the forward movement of the side template 4 and the hollow form frame 7 and the adjustment of the pouring slope adjustment mechanism 8, conditions are created for the layout of the steel bars and the pouring of the concrete, ensuring the accuracy of the pouring process. Finally, the automation of the entire demoulding and pouring process significantly improves the construction efficiency of the bridge-building machine 3, reduces the difficulty and labor intensity of manual operation, and improves the construction safety, thereby realizing efficient, accurate and safe bridge construction.

Through the inclined setting of the inclined lifting plate 111, the contact surface between the side formwork 4 and the concrete is pushed off to realize the demoulding operation.
