[0040] In addition, the technical solutions of each embodiment of the present application can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0041] For example, Figure 1The fixed structure of the baffle mold disclosed by the embodiment mainly comprises a base 1, a pressing seat 2, a sliding piece 3, a pull rod 4 and an adjusting piece 5. The base 1 is provided with a connecting structure for fixing the base 1 on the outside of a box girder outer mold 6. The first end of the pressing seat 2 is supported on the base 1, and the second end of the pressing seat 2 is provided with a pressing piece 201 for pressing the baffle mold 7 on the box girder outer mold 6 downward and inward. The pressing seat 2 is provided with a strip-shaped slot 202 arranged along the inside-outside direction, and the inside end of the strip-shaped slot 202 is higher than the outside end. The sliding piece 3 is slidingly connected in the strip-shaped slot 202. The inside-outside direction is the width direction of the box girder outer mold 6, the inside direction is the direction close to the box girder outer mold 6, and the outside direction is the direction away from the box girder outer mold 6.

[0042] The first end of the pull rod 4 is connected with the sliding piece 3, and the second end of the pull rod 4 extends downward and is connected with the adjusting piece 5, so that the vertical position of the pull rod 4 can be adjusted under the action of the adjusting piece 5, that is, the pull rod 4 can be vertically displaced within a certain range, thereby driving the sliding piece 3 to slide in the strip-shaped slot 202. Since the strip-shaped slot 202 is inclined, when the positions of the pull rod 4 and the sliding piece 3 in the inside-outside direction are relatively fixed, the sliding of the sliding piece 3 in the strip-shaped slot 202 will drive the pressing seat 2 to displace in the inside-outside direction, and the displacement of the pressing seat 2 in the inside-outside direction can realize the fixing and unlocking of the baffle mold 7. Since the inside end of the strip-shaped slot 202 is higher than the outside end in the embodiment, when the pull rod 4 drives the sliding piece 3 to displace downward, the sliding piece 3 will slide to the outside end in the strip-shaped slot 202, thereby driving the pressing seat 2 to displace inward, and thereby pressing the baffle mold 7 inward. At the same time, the pull rod 4 also provides a downward pressing force to press the baffle mold 7 inward by the pressing seat 2, so that the baffle mold 7 is attached to the box girder outer mold 6. When demolding, the position of the pull rod 4 can be adjusted upward, and the pressing seat 2 can be slid outward to complete the unlocking of the baffle mold 7.

[0043] In the specific implementation process, the pressing seat 2 comprises a first bottom plate 203 and two ear plates 204 which are parallel and spaced apart on the first bottom plate 203. The ear plates 204 are welded and fixed with the first bottom plate 203, the strip-shaped slot 202 is opened on the two ear plates 204, and the sliding piece 3 is slidingly connected on the two ear plates 204. Meanwhile, the first bottom plate 203 is provided with a strip-shaped first through hole 205 corresponding to the position of the strip-shaped slot 202. The first end of the pull rod 4 is located between the two ear plates 204 and connected with the sliding piece 3, and the second end of the pull rod 4 passes through the first through hole 205 and is connected with the adjusting piece 5. At this time, the adjusting piece 5 can be arranged at the bottom of the pressing seat 2, for example, the second end of the pull rod 4 can be arranged as a screw rod, and a locking nut is used as the adjusting piece 5. The second end of the pull rod 4 is threadedly connected with the adjusting piece 5, and the adjusting piece 5 is tightly arranged at the bottom of the pressing seat 2, so as to realize the fixation of the pull rod 4, and the vertical position of the pull rod 4 can be adjusted by adjusting the threaded connection depth between the pull rod 4 and the adjusting piece 5.

[0044] Because the base 1 exists below the pressing seat 2, it is inconvenient to directly operate the adjusting piece 5 at the bottom of the pressing seat 2. Therefore, as preferred in the embodiment, the second through hole 101 is arranged on the base 1, and the second end of the pull rod 4 is connected with the adjusting piece 5 after sequentially passing through the first through hole 205 and the second through hole 101. At this time, the second end of the pull rod 4 can also be arranged as a screw rod, and a nut is directly used as the adjusting piece 5. When the second end of the pull rod 4 passes through the first through hole 205 and the second through hole 101, the adjusting piece 5 is threadedly connected with the second end of the pull rod 4, and the adjusting piece 5 abuts against the bottom of the base 1. By adjusting the threaded connection depth of the pull rod 4 and the adjusting piece 5, the vertical position of the pull rod 4 can be adjusted, thereby driving the pressing seat 2 to displace.

[0045] Further specifically, the sliding piece 3 is a pin shaft, the first end of the pull rod 4 is provided with a lifting ring or a lifting hook, and the first end of the pull rod 4 is hung on the sliding piece 3. At this time, the lifting ring screw can be directly used as the pull rod 4, and the pull rod 4 and the adjusting piece 5 jointly form a knuckle bolt structure.

[0046] As a preferred embodiment, the base 1 includes a top plate 102 and a second bottom plate 103, the second bottom plate 103 is located below the top plate 102, and the second bottom plate 103 is connected with the top plate 102 through a web plate 104. At this time, the top plate 102 and the second bottom plate 103 can be directly used as the connecting structure on the base 1, for example, the top plate 102 and the second bottom plate 103 can be directly welded on the outside of the box girder outer form 6. The second through hole 101 is arranged on the top plate 102 and the second bottom plate 103, and the second end of the pull rod 4 is connected with the adjusting piece 5 after sequentially passing through the top plate 102 and the second bottom plate 103, and the adjusting piece 5 abuts against the bottom of the second bottom plate 103. The top plate 102, the second bottom plate 103 and the web plate 104 form the base 1, which can increase the strength of the base 1 and ensure the fixing effect of the pressing seat 2. On the other hand, the two second through holes 101 are matched with the pull rod 4, so as to avoid the inclination of the pull rod 4 due to the gap between the pull rod 4 and the single second through hole 101.

[0047] It is worth noting that in the specific application process, the knuckle bolt structure is not limited to being used as the pull rod 4 and the adjusting piece 5. For example, the oil cylinder can be directly used as the adjusting piece 5. When the second end of the pull rod 4 passes through the first through hole 205 and the second through hole 101 and is connected with the piston rod of the oil cylinder, the vertical position of the pull rod 4 can also be adjusted under the driving of the oil cylinder while the pull rod 4 is fixed.

[0048] As a preferred embodiment, the contact surface of the pressing piece 201 with the baffle form 7 is an arc surface. For example, the round steel welded on the second end of the pressing seat 2 can be directly used as the pressing piece 201, so that the pressing piece 201 can press the baffle form 7 downward and inward, and effectively avoid the welding seam of the baffle form 7.

[0049] As the preferred implementation, the bottom of the first end of the pressing seat 2 is provided with a cushion block 206, the first end of the pressing seat 2 is supported on the base 1 through the cushion block 206, the pressing seat 2 is lifted through the cushion block 206, and the pressing seat 2 is cooperated with the pressing part 201 to form an arch shape as a whole, so that local stress concentration is avoided to cause the pressing seat 2 to be deformed or the base 1 to be crushed.

[0050] The above is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings or directly / indirectly applied in other related technical fields under the utility model concept of the utility model is included in the protection scope of the utility model.
