[0062] A lifting cylinder 4 is used for lifting the upper side plate 11;

[0063] Two moving assemblies, each of the moving assemblies is provided corresponding to the support structure 2, and the moving assembly is used for driving the support structure 2 to move towards or away from the corresponding side die.

[0064] In the embodiment, the base die 3 is slidingly arranged on the installation ground 20, and the support plate 21 is slidingly arranged on the installation ground 20 through the support wheel set 24.

[0065] Please refer to Figure 1 and Figure 2 In the present application, the adjustable hydraulic formwork system for prefabricated beam production can be matched with a core die 30, a demolding oil cylinder 40, an anti-floating frame 50 and an end formwork (not shown in the figure) to complete the preparation of the prefabricated beam.

[0066] In the preparation process of the prefabricated beam, the two ends of the anti-floating frame 50 are installed on the top of the support structure 2 through a screw rod structure. The core die 30 is arranged between the two side dies, and a mold cavity is formed between the core die 30, the side die and the base die 3; the core die 30 is connected with the anti-floating frame 50 through a connecting arm 501, and the anti-floating frame 50 is used for resisting the “buoyancy” generated in the concrete pouring process to make the core die 30 move upwards.

[0067] Please refer to Figure 2The anti-floating frame 50 is horizontally telescopic to meet the distance requirement when the moving assembly drives the two support structures 2 to separate the two side molds.

[0068] The demolding oil cylinder 40 is horizontally installed on the support structure 2 through the mounting frame. After forming, the demolding oil cylinder 40 is used to push the precast beam to separate the side mold from the precast beam in cooperation with the moving assembly. Preferably, multiple demolding oil cylinders 40 can be provided on the two support structures 2.

[0069] The end formwork is used to block the two ends of the mold cavity. When the height of the precast beam changes, the size of the end formwork is adjusted accordingly.

[0070] When it is necessary to replace the side mold of different heights, first, the upper side plate 11 and the lower side plate 12 in each single side plate 1 are unlocked, then the upper side plate 11 is lifted by the lifting cylinder 4 to separate the upper side plate 11 from the lower side plate 12, and the lower side plate 12 is taken out. Among them, multiple lower side plates 12 can be unlocked in sequence and then taken out piece by piece.

During the assembly of the lower side plate 12, the height of the upper side plate 11 is adjusted by the lifting cylinder 4, and the horizontal position of the upper side plate 11 is adjusted by the moving assembly through the support structure 2, so that the upper side plate 11 can be smoothly assembled with the lower side plate 12.

[0072] When it is necessary to adjust the length of the formwork to adapt to different beam lengths, a predetermined number of single side plates 1 can be continued to be spliced at the end of the side mold; and the corresponding support structure 2 is additionally provided.

[0073] By replacing only the lower side plate 12, the beam height is adjusted, which has less replacement components compared to replacing the entire side mold, reduces the amount of steel used and the number of idle formworks to be stored, reduces the construction cost, and improves the production line conversion speed.

[0074] The length of the bottom mold 3 can be set to adapt to the maximum length of the precast beam, or increased by splicing.

[0075] The lower side plate 12 can be separated from the upper side plate 11 by using a winch traction device to pull the bottom mold 3, or removed by a mold moving vehicle or a crane.

[0079] The connection part of the adjacent single side plate 1 is provided with a sealing strip, so as to ensure the sealing performance of the connection part.

[0080] Please refer to Figure 4 In the embodiment, a plurality of groups of hole positions are arranged on one side of the upper side plate 11 and the lower side plate 12, each group of hole positions comprises a positioning hole 101 and a threaded hole 102, and a plurality of first mounting plates 13 are correspondingly arranged on the other side of the upper side plate 11 and the lower side plate 12. Each first mounting plate 13 is provided with a plug hole corresponding to each group of positioning holes 101 and threaded holes 102;

[0081] When the adjacent single side plates 1 are spliced, the plug holes on each first mounting plate 13 are respectively aligned with the positioning holes 101 and the threaded holes 102. First, the positioning pin 16 is inserted into the positioning hole 101 through the plug hole, the two single side plates 1 are aligned by arranging the positioning pin 16 and the positioning hole 101, and then the bolt 15 is screwed with the threaded hole 102 through the plug hole, so as to realize the connection.

[0086] The both ends of the anti-floating frame 50 are installed on the top plate 23 through the screw rod structure, and the stripping oil cylinder 40 is horizontally installed on the top plate 23.

[0087] Preferably, the upper end of the support column 22 and below the upper side plate 11 is threadedly connected with a support ring, or a horizontal threaded insertion pin, for supporting the upper side plate 11.

[0088] The top side of the upper side plate 11 is provided with a plurality of circular holes corresponding to the support column 22, the support column 22 penetrates the circular hole and is installed with the support plate 21, and the bottom end of the support column 22 is provided with a threaded shaft, which penetrates the support plate 21 and is connected through a nut.

[0091] Please refer to Figure 1 and Figure 2 Both sides of the bottom die 3 are provided with grooves 31, and the bottom of the lower side plate 12 is provided with a flange 121, and the flange 121 is embedded in the groove 31.

[0092] By arranging the flange 121 and the groove 31, the assembly of the lower side plate 12 and the bottom die 3 is embedded, and the sealing performance of the connection is improved.

[0093] And a sealing rubber strip is arranged on the surface of the flange 121 or in the interior of the groove 31, further improving the sealing performance of the connection.

[0094] Please refer to Figure 2One end of the support plate 21 is obliquely provided with a plurality of baffles 211 for supporting the lower side plate 12.

[0095] By providing a plurality of baffles 211, the lower side plate 12 is assisted and supported, so that the lower side plate 12 can more stably bear the pouring materials such as concrete during the preparation of the precast beam.

[0096] Please refer to Figure 1 and Figure 5 In the embodiment, the moving assembly includes a first translation structure 6, a second translation structure 7, and a first longitudinal sliding rail 5, the first translation structure 6 is slidingly installed on the first longitudinal sliding rail 5, and the second translation structure 7 is spaced apart from the first translation structure 6.

[0099] The first translation structure 6 is movably arranged through the first longitudinal sliding rail 5. Since the entire side mold can be increased in length by splicing the single side plate 1 to adapt to different box girder lengths, after the length of the side mold is increased, the positions of the first translation structure 6 and the second translation structure 7 can be adjusted so that they are symmetrically arranged on both sides of the side mold, so that the force applied to the side mold by the support structure 2 is more uniform, and the overall rigidity of the mold is ensured.

[0100] The first translation structure 6 and the second translation structure 7 can be provided in multiple numbers according to use requirements.

[0101] In the embodiment, each support structure 2 corresponds to one first translation structure 6 and one second translation structure 7.

[0102] In other embodiments, the first translation structure 6 and the second translation structure 7 can also be slidingly arranged.

[0103] As an optional mode of the present embodiment, the first translation structure 6 and the second translation structure 7 are both screw conveying structures or belt conveying structures, etc., which are used to drive the support structure 2 to move the corresponding side mold.

[0104] Please refer to Figure 6As another alternative of the present embodiment, the first translation structure 6 comprises a sliding platform 61, a push cylinder 62 and an assembling plate 63, the sliding platform 61 is slidingly installed on the first longitudinal sliding rail 5, the push cylinder 62 is installed on the sliding platform 61 through the assembling plate 63, and the output end of the push cylinder 62 is detachably connected with the support plate 21.

[0106] The second translation structure 7 comprises a mounting platform and a push cylinder 62, and the push cylinder 62 is fixedly installed on the mounting ground 20 through the mounting platform.

[0107] When the precast beam is prepared, the push cylinder 62 pushes the side mold to move through the support structure 2, so that the lower side plates 12 in the two side molds are embedded and spliced with the two sides of the bottom mold 3 to form a precast mold cavity with the core mold 30.

[0108] Subsequently, when the precast beam is formed, the push cylinder 62 pulls the side mold to move away from the precast beam through the support structure 2, so that the side mold is separated from the precast beam, facilitating the subsequent transportation of the precast beam by the bottom mold 3 to other processes.

[0109] Since the entire side mold is spliced and increased by the single side plate 1 to adapt to the length of different box beams, after the length of the side mold is increased, the position of the first translation structure 6 is adjusted, so that the first translation structure 6 and the second translation structure 7 can be symmetrically arranged on the two sides of the side mold, so that the force applied to the side mold by the support structure 2 is more uniform, and the demand for overall rigidity of the formwork is ensured, therefore, the limiting device 9 is needed to limit the first translation structure 6 after moving to the preset position, so as to ensure the subsequent stable driving of the support structure 2 to move the side mold.
