Description

Technical Field

[0001] This invention belongs to the technical field of bridge prefabrication equipment, specifically relating to a box girder outer formwork with rigid path isolation elastic suspension for vibration energy. Background Technology

[0002] As a core load-bearing component in the construction of high-speed railway and highway bridges, the prefabrication quality of box girders directly determines the safety and durability of bridge projects. With the advancement of the "smart beam yard" construction model, box girder prefabrication has gradually shifted from traditional labor-intensive operations to a factory-based, assembly-line intelligent manufacturing model. In the standard box girder prefabrication process, the "fixed bottom formwork, moving side formwork" operation method is usually adopted: first, the bottom formwork is placed on a long strip base and the reinforcing steel is tied; then, a hydraulic drive system is used to control the large side formwork components on both sides to close inward, connecting with the bottom formwork to form a closed pouring cavity. During the concrete pouring process, in order to ensure the density and appearance quality of the concrete, high-frequency attached vibrators are usually arranged on the outside of the side formwork. High-intensity vibration force is used to expel air bubbles inside the concrete, causing it to change from a fluid state to a solid state.

[0003] Existing box girder external formwork devices primarily employ rigid support structures, where the bottom formwork assembly is directly and rigidly fixed to a concrete platform or metal base, and the side formwork assemblies are also rigidly connected to the base via rigid bolts or locking mechanisms after mold closing. This rigid structure presents the following technical drawbacks in actual production: First, under vibration conditions, the high-frequency excitation force generated by the side formwork is transmitted to the base assembly, foundation, and precision hydraulic drive components through the rigid connection path. This vibration easily leads to hydraulic system seal failure, servo valve damage, and foundation fatigue cracking, shortening the maintenance cycle of expensive equipment. Second, the rigid connection causes a significant amount of vibration energy to dissipate to the foundation, preventing it from being concentrated on the concrete interior and reducing vibration efficiency. Furthermore, the rigid bottom formwork lacks flexible floating capability and cannot adaptively eliminate processing or installation errors when the side formwork is closed, easily causing hard impact wear at the formwork openings or grout leakage due to loose mold gaps. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a box girder outer formwork with a rigid path isolation type elastic suspension for vibration energy, so as to solve the problem of damage to equipment and foundation caused by rigid transmission of vibration energy in the box girder outer formwork in the prior art.

[0008] Optionally, the side mold assembly further includes a frame-shaped bracket fixed to the outside of the side mold plate. The bottom of the frame-shaped bracket is provided with a plurality of second pulley structures.

The top surface of the side base is provided with a second slide rail that cooperates with the second pulley structure.

[0009] Optionally, the inner end chamber is provided with an automatic locking mechanism, which includes a drill, an inner cylinder, and a threaded locking component; the drill is installed in the inner end chamber, and its output end is connected to the inner cylinder through a telescopic transmission shaft; the threaded locking component is slidably disposed in the inner cylinder, and the front end of the threaded locking component passes through the side template and points to the long strip bottom plate.

[0010] Optionally, the threaded locking component includes a hexagonal head that slides within the inner cylinder and a threaded post fixedly connected to the front end of the hexagonal head. A first return spring is provided between the hexagonal head and the bottom of the inner cylinder. The inner cylinder has a hexagonal elongated limiting hole that matches the hexagonal head, and the side of the elongated bottom plate has a threaded hole that mates with the threaded post.

[0011] Optionally, a linkage stabilizing mechanism is also included, which includes a stop rod that is laterally slidably disposed in the side base. The stop rod can pass through the slide cylinder and abut against the end of the slide column.

[0015] The beneficial effects of this invention are as follows: This device achieves a rigid physical isolation of the vibration energy path. By setting an elastic housing component consisting of a sliding cylinder and a supporting spring within the groove of the central base, the long base plate is in an "elastic floating" state during operation. This structural design physically severs the hard connection path for the transmission of high-frequency vibration energy to the base component and the foundation. This not only concentrates and confines the excitation force within the concrete, significantly improving the density and appearance quality of the box girder, but more importantly, it effectively blocks the transmission of destructive vibration to the foundation structure, avoiding fatigue cracking of the base and loosening of the foundation caused by long-term high-frequency vibration, and greatly improving the structural reliability of the equipment.

[0016] This flexible suspension structure endows the mold with adaptive and flexible mold closing capabilities. Combined with the side mold horizontal displacement controlled by the lateral drive assembly, when the side mold aligns with the base plate, the suspended base plate can self-correct its posture using the slight deformation of the springs. This flexible contact mechanism effectively compensates for machining or installation errors in large structural components, ensures the tightness of the mold joints, eliminates slurry leakage, and avoids the hard impact wear at the mold opening caused by traditional rigid mold closing, significantly extending the mold's service life.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0021] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0022] This invention provides a box girder outer formwork with a rigid path isolation type elastic suspension for vibration energy, aiming to solve the problems of destructive backlash of side formwork vibration energy on hydraulic drive systems and low vibration efficiency of traditional rigid bolt connections in precast beam production.

[0023] like Figure 1 As shown, the device includes a base plate assembly that serves as the load-bearing foundation and has elastic floating capability, a base assembly that suspends and supports the cast box girder, a side mold assembly that integrates vibration and molding functions, and a lateral drive assembly that provides automated power.

[0024] For details, please refer to Figure 1 , Figure 2 and Figure 5The main structure of the base plate assembly is a long strip base plate 110, the length of which is equal to that of the box girder to be precast. To prevent leakage of concrete grout during pouring, sealing strips 130 are inlaid along the extension direction of both sides of the long strip base plate 110. On the bottom surface of the long strip base plate 110, several first pulley structures are arranged to achieve longitudinal movement or fine adjustment. The first pulley structure adopts a structure of two spaced first clamping plates 141 and clamping first rollers 142. The circumferential surface of the first rollers 142 is machined with an inner groove structure 143. The base assembly includes a long strip-shaped central base 210 located in the center and side bases 220 symmetrically connected on both sides of the central base 210. The top surface of the central base 210 has a long strip groove 211 that runs through its entire length, and the bottom surface of the long strip groove 211 is covered with a first slide rail 212 that cooperates with the first pulley structure. On the inner sidewall of the elongated groove 211 of the intermediate base 210, a plurality of sliding cylinders 231 are arranged vertically. Each sliding cylinder 231 contains a supporting spring 232. Correspondingly, a plurality of sliding columns 120 are fixedly installed on the two sidewalls of the elongated base plate 110. When the elongated base plate 110 is placed in the elongated groove 211, the sliding columns 120 are inserted into the sliding cylinders 231 and elastically supported by the supporting springs 232. In its natural state or during the casting process, the elongated base plate 110 is suspended above the intermediate base 210. This elastic suspension structure breaks the rigid connection between the base plate assembly and the base assembly.

[0025] For details, please refer to Figure 4 and Figure 5The side mold assembly includes the side template 310 and a frame-shaped support 330 welded to the outside of the side template 310. Multiple high-frequency attached vibrators 320 are arranged on the outer surface of the side template 310. To enable the opening and closing of the side mold, the bottom of the frame-shaped support 330 is provided with a second pulley structure. The second pulley structure includes two spaced-apart second clamping plates 341 and a second roller 343 disposed between them. Several second slide rails 221 are arranged along the extending direction of the top surface of the side base 220. The second pulley structure cooperates with the second slide rails 221 for horizontal sliding. The lateral movement drive assembly includes a hydraulic cylinder 410. A support baffle 240 is fixedly provided on the side of the side base 220 away from the central base 210. The height of the support baffle 240 is higher than the top surface of the side base 220. The hydraulic cylinder 410 is fixedly installed on the support baffle 240, and the hydraulic cylinder 410 is driven by a stop cylinder 510. The internal structure of the cylinder 510 is divided into an independent inner end chamber 512 and an outer end chamber 511. The output end of the hydraulic cylinder 410 extends into the outer end chamber 511, and a disc 411 is fixed to the output end of the hydraulic cylinder 410. The disc 411 is slidably disposed within the outer end chamber 511. When the hydraulic cylinder 410 pushes and pulls, it can contact the end walls at both ends of the outer end chamber 511 to transmit force, but in the middle position, the disc 411 is in a suspended state.

[0026] For details, please refer to Figure 5 A drilling rig 521 is installed inside the inner chamber 512. The output end of the drilling rig 521 is connected to a telescopic drive shaft 522, such as a splined bushing or a square tenon sleeve structure. The telescopic drive shaft 522 is connected to an inner cylinder 523, in which a threaded locking component is slidably installed. The threaded locking component consists of a hexagonal head 531 and a threaded post 532 at its front end. The hexagonal head 531 is pressed against the inner cylinder 523 by a first return spring 533. The inner wall of the inner cylinder 523 is machined with a hexagonal elongated limiting hole 524 that matches the hexagonal head 531. The long base plate 110 has a threaded hole 150 on its side corresponding to the threaded post 532. When the drilling rig 521 rotates, the threaded post 532 is screwed into the threaded hole 150 on the side of the long base plate 110, which will generate a forward feed displacement. At this time, the telescopic transmission shaft 522 is extended, and the hexagonal head 531 is pushed forward under the action of the first return spring 533.

[0027] For details, please refer to Figure 6A plurality of abutment rods 610 are transversely inserted inside the side base 220 along the extending direction, and the abutment rods 610 are directly opposite the slide cylinder 231 on the middle base 210. A row of meshing teeth 342 is machined on the lower side of the second clamping plate 341 of the second pulley structure at the bottom of the side mold assembly. A gear 640 is installed on the side base 220, and a rack 630 connected to the abutment rods 610 is slidably arranged below it. An abutment ring 620 is provided in the middle section of the abutment rod 610. A sliding groove 222 is opened in the side base 220 for the abutment ring 620 to slide. A second return spring 650 is sleeved on the abutment rod 610 in the sliding groove 222, and the second return spring 650 abuts against the abutment ring 620. When the side mold assembly retracts outward, the second clamping plate 341 moves toward the gear 640 and eventually meshes with the gear 640, thereby causing the gear 640 to rotate and driving the rack 630 to forcibly push out the abutment 610. The abutment 610 passes through the slide cylinder 231 and abuts against the end of the slide post 120 on the side of the elongated base plate 110. When the side mold assembly moves inward, the gear 640 reverses and disengages, and the abutment 610 retracts into the side base 220 under the action of the second return spring 650, and the elongated base plate 110 returns to its elastic suspension state.

[0028] In addition, such as Figure 1 The outer formwork device is also equipped with end plates at both ends, which are used to seal the ends of the box girder and support the inner formwork.

[0029] The operating steps of this device are as follows: Before the pre-molding process begins, the side mold assembly is in the demolding position with its maximum opening. At this time, since the side mold assembly is located on the outermost side, the abutment rod 610 is in the extended state through the gear 640 of the linkage stabilizing mechanism, passing through the slide cylinder 231 and tightly abutting against the slide column 120 of the elongated base plate 110. The elongated base plate 110 is in a rigid fixed state.

[0030] When the mold is closed, the hydraulic cylinder 410 is activated, and the disc 411 located in the outer end chamber 511 of the abutment cylinder 510 moves forward until it abuts against the inner end face of the outer end chamber 511, thus pushing the side mold assembly to slide inward along the second slide rail 221. As the side mold assembly moves inward, the meshing teeth 342 at its bottom drive the gear 640 on the side base 220 to rotate in the opposite direction. The gear 640 drives the rack 630 to retract. When the side mold assembly moves close to the elongated base plate 110, the abutment rod 610 automatically retracts under the tension of the second return spring 650, and the abutment rod 610 is completely retracted into the side base 220 and exits the slide cylinder 231. At this time, the sliding column 120 of the elongated base plate 110 is no longer restricted and is supported by the support spring 232 inside the slide cylinder 231. The elongated base plate 110 switches from a rigidly locked state to an elastically suspended state, and adapts to minor positional errors when the side mold assembly is closed.

[0031] When the side mold assembly is pressed tightly against the side of the elongated base plate 110, the hydraulic cylinder 410 stops operating. At this time, the automatic locking mechanism in the inner end chamber 512 is activated. The drilling rig 521 begins to rotate, driving the telescopic drive shaft 522 and the inner cylinder 523 to rotate. The inner cylinder 523 drives the threaded locking member to rotate. The front end of the threaded post 532 contacts the threaded hole 150 on the side of the elongated base plate 110. With continuous rotation, the first return spring 533 abuts against the threaded post 532, engages with the threaded hole 150, and begins to screw in. Finally, the threaded post 532 is fully screwed in, tightly pulling the side mold assembly and the elongated base plate 110 together. During this process, the telescopic drive shaft 522 adaptively extends to compensate for the displacement caused by the compression of the inner cylinder 523, the abutment cylinder 510, and the side mold plate 310 when the threaded locking member is locked.

[0032] After locking is completed, the control system instructs the hydraulic cylinder 410 to retract slightly. At this time, the disc 411 retracts from the inner end face of the outer end chamber 511 and stops in the middle of the outer end chamber 511 without contacting any wall surface. Subsequently, the end plate, inner mold, and inner reinforcement are installed, and concrete is poured. After pouring is completed, the vibrator 320 is activated simultaneously. Since the disc 411 of the hydraulic cylinder 410 is in a suspended state, the violent vibration of the vibrator 320 is physically isolated, and most of the vibration will not be transmitted back to the interior of the hydraulic cylinder 410 through the rigid output end. At the same time, since the long strip base plate 110 is in an "elastic suspension state," the entire mold is actually floating on the base assembly. Most of the vibration of the vibrator 320 is not rigidly transmitted through the base supporting the mold, but is transmitted to the interior of the poured beam.

[0033] After the box girder is formed, during the demolding process, the drilling rig 521 reverses, and the threaded column 532 exits the threaded hole 150. Subsequently, the hydraulic cylinder 410 retracts, and the disc 411 moves backward until it impacts the outer end face of the outer end chamber 511, pulling the side mold assembly outward. As the side mold assembly moves outward, the meshing teeth 342 at the bottom re-engage, driving the gear 640 to rotate and forcefully pushing out the abutment rod 610. The abutment rod 610 re-inserts into the slide cylinder 231, locking the slide column 120. The elongated bottom plate 110 is locked back to a rigid state the instant the side mold assembly is fully opened.

[0034] This invention utilizes a sliding cylinder 231 and a supporting spring 232 to construct an elastic support system for the base plate assembly. This structure reduces the dissipation of vibration energy to the base assembly and foundation. The elongated base plate 110 is in a suspended state, allowing more vibration energy to be reflected back into the concrete, thus improving the concrete's density. Secondly, this invention introduces a stop cylinder 510 and a suspended disc 411 between the transverse drive assembly and the side mold assembly. During vibration, a physical circuit is created by the slight retraction of the hydraulic cylinder 410. The high-frequency vibration generated by the vibrator 320 is confined to the mold side and is not forcibly transmitted to the hydraulic cylinder 410, avoiding the problem of long-term wear and tear on the hydraulic cylinder 410 components. Furthermore, an automatic locking unit composed of the drill rig 521, the telescopic drive shaft 522, and the threaded locking element is integrated into the inner end chamber 512. The cooperation between the telescopic transmission shaft 522 and the first return spring 533 allows the threaded post 532 to retract and automatically optimize when not fully aligned, and automatically compensates for the axial feed during screwing, solving the problem of difficult automatic thread connection of large structural components. Finally, the side mold uses the transmission of the gear 640 and the rack 630 to convert the horizontal displacement of the side mold assembly into the lateral locking action of the stop rod 610. When the side mold assembly is open, the long strip base plate 110 automatically becomes a stable rigid platform; when the side mold assembly is closed, the long strip base plate 110 automatically becomes a flexible vibration platform, realizing rapid switching between the two states.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
