Description

Technical Field

[0001] The present invention relates to the technical field of formwork mechanisms for bridge erectors, and particularly to a formwork mechanism for a bridge erector with multi-directional adjustment. Background Art

[0002] The traditional cantilever cast-in-situ bridge erector formwork mechanism is a key device for bridge cantilever casting construction, mainly used to support and form the concrete structure of bridge segments. Its core function is to provide precise geometric dimensions and surface shapes through the formwork system to ensure the stability and construction accuracy of the bridge structure.

[0003] Currently, the cantilever cast-in-situ bridge erector formwork mechanism needs to be hoisted, aligned, and fixed piece by piece. The formwork erection for a single-span beam usually takes 2 - 3 days, and it relies on a large amount of manual labor. It is easy to cause insufficient assembly accuracy due to human operation errors. Moreover, the traditional formwork size is a fixed structure, and exclusive formworks need to be customized according to different bridge types, such as simply supported beams and continuous beams. After the project is completed, the idle rate of the formwork is high, resulting in serious waste of resources.

[0004] Therefore, aiming at the problems of low formwork erection efficiency, high labor cost, difficult size adjustment, and poor adaptability of the above formwork mechanism, a formwork mechanism for a bridge erector with multi-directional adjustment can be designed. Summary of the Invention

[0005] In order to overcome the problems of low formwork erection efficiency, high labor cost, difficult size adjustment, and poor adaptability of the traditional formwork mechanism.

[0006] The technical solution is as follows: A formwork mechanism for a bridge erector with multi-directional adjustment, including a fixed bottom plate; on one side of the upper end of the fixed bottom plate, a lifting control column is installed that can adjust the pouring height according to the needs of pouring different sizes. At the outer end of one side of the lifting control column, a two-end adjustment component for adjusting the pouring length of the size is installed. Outside the two-end adjustment component, a synchronous adjustment component for horizontally adjusting the pouring width of the size is installed. On the upper end of the fixed bottom plate, two groups of guiding vertical rods symmetrically distributed on both sides of the lifting control column are installed. At the upper end of the lifting control column, a first servo motor is installed. The output end of the first servo motor is installed with an adjustment screw rod. The outer side of the adjustment screw rod is threadedly connected with a screw rod slider. On both sides of the screw rod slider, linkage guiding rods are fixedly connected. The side end of the linkage guiding rod is fixedly connected with a limit slider.

[0007] Further, a limit sliding groove is opened inside the guiding vertical rod, and the limit slider slides inside the limit sliding groove. A through groove for facilitating the movement of the linkage guiding rod to pass through is penetrated and opened inside the lifting control column.

[0008] Further, a moving block is fixedly connected to the side end of the screw rod slider. The lower end of the guiding vertical rod is installed with a stable base through bolts, and the stable base is welded and fixed to the fixed bottom plate.

[0009] Further, inside the two - end adjusting component, there is a lateral control cylinder installed on the side of the moving block. Inside the lateral control cylinder, a bidirectional servo motor is installed. The output end of the bidirectional servo motor is equipped with a bidirectional screw rod, and two relatively moving movable sleeve blocks are threadedly connected to the outside of the bidirectional screw rod.

[0010] Further, the output shaft of the bidirectional servo motor is rigidly connected to the left end of the bidirectional screw rod through a plum - blossom elastic coupling. The left section of the bidirectional screw rod is a left - hand trapezoidal thread, and the right section is a right - hand trapezoidal thread. The left end of the bidirectional screw rod is installed in the bearing seat of the left end cover of the lateral control cylinder through a deep - groove ball bearing, and the right end is installed in the bearing seat of the right end cover of the lateral control cylinder through an angular contact bearing. The outer ring of the bearing is axially fixed by a shaft - use elastic retaining ring.

[0011] Further, a linear slider is fixedly connected to the outside of the movable sleeve block, and an installation cross - bar is fixedly connected to the lower end of the lateral control cylinder.

[0012] Further, inside the synchronous adjusting component, there is an adjusting cross - plate installed on the side of the linear slider. A cylinder is installed outside the adjusting cross - plate. An adjusting cavity is opened inside the adjusting cross - plate, and the output end of the cylinder is equipped with a linkage plate.

[0013] Further, an inner adjusting plate that slides inside the adjusting cavity is installed on the side of the linkage plate. First installation grooves are opened at the bottom ends of both the adjusting cross - plate and the inner adjusting plate.

[0014] Further, a splicing installation side - plate is installed on the side of the inner adjusting plate, and a second installation groove is opened at the bottom end of the splicing installation side - plate.

[0015] The beneficial effects are as follows: In the present invention, the first servo motor can drive the adjusting screw rod to rotate, enabling the screw rod slider to move up and down, thereby achieving height adjustment with millimeter - level precision to meet the needs of pouring at different heights. The two - end adjusting component can adjust the pouring length according to the pouring requirements of different sizes, and at the same time, the synchronous adjusting component can quickly adjust the pouring width. Compared with the traditional cantilever in - situ bridge - building machine formwork mechanism, which has low formwork - supporting efficiency, high labor cost, difficult size adjustment, and poor adaptability, this formwork mechanism can reduce the on - site assembly time, avoid the errors and time - consuming problems of traditional manual formwork adjustment, be compatible with multiple sizes, and reduce the formwork cost.

Detailed implementation manners

[0023] The following is a specific introduction to the present invention in combination with the attached drawings and specific embodiments.

[0024] As Figures 1-6 shown, the present invention provides an embodiment, which has a formwork mechanism of a bridge erector with multi-directional adjustment, including a fixed bottom plate 1; on one side of the upper end of the fixed bottom plate 1, a lifting control column 2 is installed, which can adjust the pouring height according to the needs of pouring with different dimensions. At the outer end of one side of the lifting control column 2, an end adjustment assembly for adjusting the pouring length of different dimensions is installed. On the outside of the end adjustment assembly, a synchronous adjustment assembly for horizontally adjusting the pouring width is installed. On the upper end of the fixed bottom plate 1, two groups of guiding vertical rods 5 symmetrically distributed on both sides of the lifting control column 2 are installed. At the upper end of the lifting control column 2, a first servo motor 201 is installed. The output end of the first servo motor 201 is installed with an adjusting lead screw 202. The outside of the adjusting lead screw 202 is threadedly connected with a lead screw slider 203. On both sides of the lead screw slider 203, linkage guiding rods 204 are fixedly connected. The side end of the linkage guiding rod 204 is fixedly connected with a limiting slider 205.

[0025] A limiting chute 501 is opened inside the guiding vertical rod 5, and the limiting slider 205 slides inside the limiting chute 501. A through groove 206 for facilitating the movement of the linkage guiding rod 204 to pass through is penetrated and opened inside the lifting control column 2.

[0026] A moving block 207 is fixedly connected to the side end of the lead screw slider 203. The lower end of the guiding vertical rod 5 is installed with a stable base 502 through bolts, and the stable base 502 is fixedly welded to the fixed bottom plate 1.

[0027] The internal of the two - end adjusting assembly includes a transverse control cylinder 301 installed on the side end of the moving block 207. A two - way servo motor 302 is installed inside the transverse control cylinder 301. The output end of the two - way servo motor 302 is installed with a two - way screw rod 303. Two sets of relatively moving movable sleeve blocks 304 are threadedly connected to the outside of the two - way screw rod 303.

[0028] The output shaft of the two - way servo motor 302 is rigidly connected to the left end of the two - way screw rod 303 through a plum - blossom elastic coupling. The left section of the two - way screw rod 303 is a left - hand trapezoidal thread, and the right section is a right - hand trapezoidal thread. The left end of the two - way screw rod 303 is installed in the bearing seat of the left end cover of the transverse control cylinder 301 through a deep - groove ball bearing 305, and the right end is installed in the bearing seat of the right end cover of the transverse control cylinder 301 through an angular contact bearing 306. The outer ring of the bearing is axially fixed by a shaft - use elastic retaining ring.

[0029] A linear slider 307 is fixedly connected to the outside of the movable sleeve block 304. An installation cross - bar 308 is fixedly connected to the lower end of the transverse control cylinder 301.

[0030] The internal of the synchronous adjustment assembly includes an adjustment cross - plate 401 installed on the side end of the linear slider 307. A cylinder 402 is installed on the outside of the adjustment cross - plate 401. An adjustment cavity 403 is opened inside the adjustment cross - plate 401. The output end of the cylinder 402 is installed with a linkage plate 404.

[0031] An inner adjustment plate 405 that slides inside the adjustment cavity 403 is installed on the side end of the linkage plate 404. The bottom ends of the adjustment cross - plate 401 and the inner adjustment plate 405 are both provided with first installation grooves 406.

[0032] A splicing installation side plate 407 is installed on the side end of the inner adjustment plate 405. A second installation groove 408 is opened at the bottom end of the splicing installation side plate 407.

[0033] When the first servo motor 201 starts, it drives the adjustment lead screw 202 to rotate. The adjustment lead screw 202 drives the lead screw slider 203 to perform a linear motion. The lead screw slider 203 drives the limit slider 205 to slide in the limit chute 501 of the guiding vertical rod 5 through the linkage guiding rod 204 to ensure the vertical motion accuracy. The moving block 207 on the side end of the lead screw slider 203 drives the two - end adjustment assembly to lift, thereby realizing the height adjustment;

[0034] The two-way servo motor 302 starts, drives the two-way screw rod 303 to rotate through the plum blossom-shaped elastic coupling. The left section of the two-way screw rod 303 is a left-handed trapezoidal thread, and the right section is a right-handed trapezoidal thread, driving the two groups of movable sleeve blocks 304 to move synchronously and in opposite directions. The movable sleeve block 304 drives the adjusting cross plate 401 to move horizontally through the linear slider 307, thereby changing the pouring length of the formwork. Through the combination of the angular contact bearing 306 and the deep groove ball bearing 305, it can bear radial and axial forces simultaneously, ensuring the transmission efficiency. The installation cross bar 308 can quickly piece together the corresponding formwork according to the height adjustment needs to achieve rapid pouring;

[0035] The air cylinder 402 starts, pushes the linkage plate 404 to slide in the adjustment cavity 403 of the inner adjustment plate 405. The inner adjustment plate 405 drives the formwork to expand or contract horizontally through the splicing installation side plate 407 to achieve width adjustment. The first installation groove 406 and the second installation groove 408 are used to quickly connect the precast formwork to form a complete pouring cavity.
