Description

Technical Field

[0001] This utility model relates to a beam yard construction device for engineering construction, and more particularly to a demolding structure for a skew box girder. Background Technology

[0002] Box girders are a common structural form in bridge engineering. Existing box girders generally have transverse diaphragms, which can be orthogonal or oblique to the centerline of the box girder. Orthogonal diaphragms are perpendicular to the main body of the box girder, and this type of structure can be demolded normally using commonly used demolding mechanisms. Oblique diaphragms are not perpendicular to the main body of the box girder. Figure 3 As shown in the figure, due to the presence of sharp angles, this structure cannot be demolded using the original demolding structure due to the obstruction of the transverse partition. Previously, workers had to disassemble the side molds to achieve demolding before installation, which was labor-intensive and not conducive to improving work efficiency. Summary of the Invention

[0003] To solve the above problems, the technical solution of this utility model is: a demolding structure for a slanted box girder, comprising a base, two parallel slide rails fixedly installed on the base, sliders fixedly installed on both sides of the mounting base, the sliders cooperating with the slide rails, a second slide rail fixedly installed on the mounting base, a connecting seat slidably installed on the second slide rail, a side mold fixedly installed on the connecting seat, a first driving device for driving the mounting seat to move along the slide rails, and a second driving device for driving the connecting seat and the side mold to move along the second slide rail.

[0004] As a further improvement of this utility model, the driving device includes a cylinder seat disposed between the two slide rails, the cylinder seat being fixedly mounted on a base, and a cylinder being mounted on the cylinder seat, the piston end of the cylinder being connected to the mounting base.

[0005] As a further improvement of this utility model, the second driving device includes a second hydraulic cylinder mounted on the mounting base, and the other end of the second hydraulic cylinder is connected to the side mold.

[0006] As a further improvement of this utility model, the power systems of both drive device one and drive device two are connected to the control device.

[0007] As a further improvement of this utility model, the end of the slide rail two near the inner side is higher.

[0008] The beneficial effects of this utility model are: it can be used for demolding both orthogonal box girders and skew box girders, has a simple structure, a wide range of applications, and helps to reduce production costs and improve production efficiency. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] exist Figure 1 , Figure 2 and Figure 4 A demolding structure for a cross-section box girder includes a base 5. The base 5 is characterized by two parallel slide rails 1 fixedly mounted on it. Slider blocks 8 are fixedly mounted on both sides of a mounting base 6, with the sliders 8 cooperating with the slide rails 1. A second slide rail 2 is fixedly mounted on the mounting base 6, and a connecting seat 7 is slidably mounted on the second slide rail 2. A side mold 9 is fixedly mounted on the connecting seat 7. A first driving device for driving the mounting base 6 to move along the slide rails 1 is mounted on the base 5, and a second driving device for driving the connecting seat 7 and the side mold 9 to move along the second slide rail 2 is mounted on the mounting base 6.

[0016] Furthermore, the drive device includes a cylinder seat disposed between the two slide rails 1, the cylinder seat being fixedly mounted on the base 5, and a cylinder 3 being mounted on the cylinder seat, the piston end of the cylinder 3 being connected to the mounting base 6.

[0017] Furthermore, the second driving device includes a second hydraulic cylinder 4 mounted on the mounting base 6, and the other end of the second hydraulic cylinder 4 is connected to the side mold 9.

[0018] Furthermore, the power systems of both drive device one and drive device two are connected to the control device.

[0019] Furthermore, the end of the slide rail 2 closer to the inner side is higher.

[0020] Slide rail 1 and slide rail 2 are perpendicular to each other.

[0021] When demolding orthogonal box girders, activate hydraulic cylinder 4. Hydraulic cylinder 4 pulls the side mold 9 outward via connecting seat 7 on slide rail 2, thus completing the demolding. To close the mold, simply reverse the operation.

[0022] When used for demolding skew box girders, the control device controls the simultaneous movement of hydraulic cylinders 3 and 4. Since the side mold moves in two perpendicular directions, its final direction of movement is the resultant direction of these two perpendicular directions, i.e., a diagonal line. By controlling the movement speed of hydraulic cylinders 3 and 4, the angle of the diagonal line can be controlled to achieve the angle required for demolding the skew box girder, thus completing the demolding action simultaneously. For mold closing, the operation is reversed.

[0023] Horizontal direction: velocity is v x Uniform linear motion, vertical direction: velocity is v y When a particle moves at a constant velocity in a straight line, and simultaneously moves in the horizontal and vertical directions, its trajectory is an oblique line, and the angle θ between the oblique line and the horizontal direction satisfies... Therefore, by controlling the movement speed of cylinder 3 and cylinder 4 through the control device, the required angle for demolding can be adjusted to suit the demolding needs of box girders with different oblique angles.
