Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a cast-in-place formwork moving mechanism. Background Technology

[0002] Modern large-scale cross-border bridges are mostly constructed using the cast-in-place method, and to save construction costs, formwork is often reused. The common existing method for reusing formwork involves assembling it when needed, disassembling it after construction is complete, and then reassembling it at the next location as the project progresses. However, this method suffers from low efficiency and wasted manpower due to repeated assembly and disassembly of formwork. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a cast-in-place formwork moving mechanism that saves manpower by eliminating the need for repeated assembly and disassembly.

[0004] The technical solution adopted in this utility model is a cast-in-place formwork moving mechanism, including a formwork component, a frame connected to the formwork component, and a moving device located below the frame. The moving device includes a frame, which includes two side sections and a connecting part for fixing the two side sections. Each side section has a rotatably mounted roller. A lifting rod is provided above the connecting part, and the frame is connected to a first driving device for driving the lifting rod to move vertically. The frame is also connected to a second driving device for driving the lifting rod to move closer to or away from the cast-in-place beam. A track is provided below the rollers. The frame rests behind the lifting rod and is supported by the lifting rod. The frame moves along the track to move the formwork component.

[0005] The first driving device of this utility model can be a cylinder, a hydraulic cylinder, a lifting motor, or a jack.

[0006] The second driving device of this utility model can be a cylinder, a hydraulic cylinder, a lifting motor, or a jack.

[0007] This utility model also includes a hydraulic motor, which is connected to the frame and drives the rollers to rotate.

[0008] The frame of this utility model includes an upper crossbeam, a lower crossbeam, and a connecting beam that fixes the upper and lower crossbeams. The lower crossbeam is connected to a support member, which includes a screw and a nut threadedly connected to the screw. The lower end of the screw is fixedly connected to a support plate, and the nut is connected to the lower crossbeam. Rotating the screw adjusts the vertical height of the support plate.

[0009] The pallet of this utility model corresponds to the track setting.

[0010] The pallet of this invention has side guards on both sides, and there is a gap between the two side guards to accommodate the track.

[0011] This utility model also includes a support plate, which is laid upward from one end of the lower crossbeam to above the upper crossbeam; the template is set tightly against the support plate.

[0012] The template component located above the skeleton of this invention has an upwardly extending baffle at its end.

[0013] The lifting rod of this utility model is located between two limiting members, and the two limiting members are fixedly connected to the vehicle frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Compared to the inefficient process of repeatedly assembling and disassembling templates in existing technologies, this invention features template components connected to a frame. A moving device is located below the frame and moves along a track. After construction is completed, a first drive device drives a lifting rod to move upwards to support the frame. Then, the first drive device drives the lifting rod to move the frame downwards, vertically away from the cast-in-place beam. A second drive device then drives the lifting rod horizontally away from the cast-in-place beam. This achieves both vertical and horizontal movement of the frame and template components away from the cast-in-place beam. At this point, the moving device moves the frame and template components along the track to the next location to be constructed, ultimately achieving the overall movement of the cast-in-place template. This invention eliminates the need for repeated assembly and disassembly to move the template, saving manpower and improving construction efficiency. Attached Figure Description

[0023] The specific structure of the frame 2 in this embodiment is as follows: The frame 2 includes an upper crossbeam 21, a lower crossbeam 22, and a connecting beam 23 that fixes the upper crossbeam 21 and the lower crossbeam 22. The lower crossbeam 22 is connected to a support member 24. The support member 24 includes a screw 25 and a nut 26 threadedly connected to the screw 25. The lower end of the screw 25 is fixedly connected to a support plate 27. The nut 26 is connected to the lower crossbeam 22. Rotating the screw 25 adjusts the vertical height of the support plate 27. The support plate 27 is set corresponding to the track 4. The support plate 27 has side flanges 271 on both sides, and there is a gap between the two side flanges 271 to accommodate the track 4.
