Description

Technical Field

[0001] The utility model relates to the field of dismantling a cap beam bottom formwork, and in particular to a cap beam bottom formwork dismantling and hoisting device. Background Art

[0002] The cap beam refers to the beam installed on the top of the frame pile pier to support, distribute and transfer the load of the superstructure. It is also called the cap beam. Its main function is to support the superstructure of the bridge and transfer all the loads to the lower structure.

[0003] When the cap beam is processed on site, it needs to be cast in a mold. After the concrete is poured and solidified, the mold needs to be removed. The bottom plate in the mold is the inclined cap beam bottom mold. In the past, a crane was used to directly lift the cap beam bottom mold using a wire rope. However, direct lifting with a wire rope cannot transfer the cap beam bottom mold in parallel, and it is also easy to damage the side of the cap beam, affecting the casting quality of the cap beam. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a cap beam bottom mold removal and lifting device.

[0005] The utility model is realized through the following technical solutions:

[0006] A cap beam bottom formwork removal and lifting device comprises an I-shaped main frame, with adjustment components for adjusting the span arranged on both sides of the I-shaped main frame, the bottom of the adjustment component is connected to the side of the bottom membrane plate through a lifting rope, and the lifting rope is sleeved with a plurality of rotating protection columns.

[0007] Further optionally, the adjustment component includes two adjustment hangers arranged in an eight-shape, one end of the adjustment hanger is hinged and fixed to one side of a sliding sleeve that is slidably connected to the middle part of the I-beam main frame, and the other end of the adjustment hanger passes through a sliding groove set at the outer end of the I-beam main frame and extends to the outside and is fixed to the suspension rope.

[0008] Further optionally, a plurality of adjustment holes are opened in the middle of the adjustment suspension rod and the I-shaped main frame, and the adjustment hole in the middle of the adjustment suspension rod is plugged and fixed with a slide groove arranged at the outer end of the I-shaped main frame through a latch.

[0009] Further optionally, the sliding kit is plugged and fixed to the adjustment hole in the middle of the I-shaped main frame through a latch.

[0010] Further optionally, the rotating protection column includes an inner sleeve sleeved on the lifting rope, an outer shell is arranged on the outer side of the inner sleeve, and an air-filled cavity is formed between the inner sleeve and the outer shell.

[0011] Further optionally, the tops of the outer ends of the four adjusting suspension rods are connected with connecting ropes connected to the crane hooks.

[0012] Compared with the existing technology, the beneficial effect of the utility model is that an eight-shaped adjustment component with adjustable width is arranged on the outside of the I-shaped main frame, so that the contact between the lifting rope and the side of the cap beam can be avoided when the bottom membrane plate of the cap beam is lifted and disassembled, and it is ensured that after the bottom mold of the cap beam is lifted, it can be moved and transferred in the air without obstacles, thereby realizing the safe dismantling function.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a cap beam bottom formwork removal and lifting device includes an I-shaped main frame 1, and adjustment components for adjusting the span are arranged on both sides of the I-shaped main frame 1. The bottom of the adjusting component is connected to the side of the bottom membrane plate 9 through a lifting rope 7. The lifting rope 7 is sleeved with a plurality of rotating protection columns 8. The lifting rope 7 adopts a steel wire rope with a diameter of 20.

[0019] like Figure 1 As shown, the adjustment assembly includes two adjustment hangers 2 arranged in an eight-shaped shape, one end of the adjustment hanger 2 is hinged and fixed to one side of a sliding sleeve 3 that is slidably connected to the middle part of the I-shaped main frame 1, and the other end of the adjustment hanger 2 passes through a slide groove set at the outer end of the I-shaped main frame 1 and extends to the outside and is fixed to the suspension rope 7. The two adjustment hangers 2 arranged in an eight-shaped shape and the I-shaped main frame 1 are in a triangle, and their stability is better.

[0020] like Figure 1 As shown, a plurality of adjustment holes 4 are opened in the middle of the adjustment suspension rod 2 and the I-shaped main frame 1, and the adjustment hole 4 in the middle of the adjustment suspension rod 2 is plugged and fixed with a slide groove arranged at the outer end of the I-shaped main frame 1 through a latch 5.

[0021] like Figure 1 As shown, the sliding kit 3 is plugged and fixed with the adjustment hole 4 in the middle of the I-shaped main frame 1 through a latch 5.

[0022] like Figure 3As shown, the rotating protection column 8 includes an inner sleeve 81 which is sleeved on the lifting rope 7. An outer shell 82 is arranged on the outer side of the inner sleeve 81. An air-filled cavity 83 is formed between the inner sleeve 81 and the outer shell 82. The formed air-filled cavity 83 has good cushioning properties, thereby preventing the lifting rope 7 from directly wearing against the side of the cap beam 10.

[0023] like Figure 1 As shown, the top of the outer ends of the four adjusting suspension rods 2 are connected with connecting ropes 6 connected to the crane hooks.

[0024] The implementation principle of the cap beam bottom formwork removal and lifting device in the embodiment of the present application is as follows:

[0025] When lifting and removing the bottom membrane plate 9 at the bottom of the cap beam 10 (such as Figure 2 As shown), the ends of the four adjusting suspension rods 2 of the I-shaped main frame 1 are fixed to the bottom membrane plate 9 through the suspension ropes 7, and the upper parts of the four adjusting suspension rods 2 are connected to the hooks of the crane through four connecting ropes 6, so that the bottom membrane plate 9 is suspended in the air and then translated away from the cap beam 10 along the outer side, and finally the bottom membrane plate 9 is dropped to realize the disassembly;

[0026] When encountering a wider bottom membrane plate 9, the latch 5 is released, and the sliding kit 3 is moved toward the outside of the I-shaped main frame 1, so that the eight-shaped adjusting suspension rod 2 will also move outward along the slide grooves on both sides of the I-shaped main frame 1 and open, so as to increase the lifting width of the eight-shaped adjusting suspension rod 2. After adjustment, the latch 5 is fixed again, and when encountering a bottom membrane plate 9 with a smaller width, the operation is performed in the opposite direction. In this way, adaptive adjustment is performed according to the bottom membrane plates 9 of different widths, so that the four suspension ropes 7 are always opened outward, avoiding the four suspension ropes 7 from contacting with the side of the inner cap beam 10 to cause damage thereto, thereby ensuring the quality of the cap beam 10;

[0027] Moreover, there are multiple rotating protective columns 8 on the lifting rope 7. The air-filled cavity 83 of the rotating protective column 8 has good cushioning properties. Even if the lifting rope 7 contacts the side of the cap beam 10, the rotating protective column 8 will rotate relatively and have good cushioning properties, avoiding direct friction damage inside the cap beam 10 and ensuring the integrity of the cap beam 10.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
