[0026] The technical solution of the present invention is further described below in conjunction with specific embodiments:
[0027] like Figure 1As shown, a hanging basket for cast-in-place wet joints of a box girder includes a hanging basket base 200 and two symmetrically arranged hanging basket frames 100. The hanging basket frames 100 include steel side frames 110, retractable protective doors 150 and hanging ears 120. The retractable protective doors 150 are arranged on the steel side frames 110. The hanging ears 120 are fixed to the top of the steel side frames 110 by first bolts. The hanging basket is fixed to the box girder steel bars by the hanging ears 120. The hanging basket base 200 is suspended on the box girder through the hanging basket frame 100. Two hanging basket frames 100 are symmetrically arranged, so that the two hanging basket frames 100 can provide side protection for the hanging basket, and at the same time, the two spaces reserved by the hanging basket can be used to cast the joints of the box girder; the retractable protective door 150 can be opened and closed when adjusted to different positions, so that workers can enter and exit the hanging basket from the position of the protective door 150; the setting of the hanging ear 120 is to fix the hanging basket at the joint of the box girder by fixing the hanging ear 120 to the steel bar of the box girder after the steel side frame 110 extends upward to the top of the box girder.
[0028] like Figure 2 As shown, the hanging basket base 200 includes two bottom rods 210, a base frame 220, a bottom plate 240, two positioning members 230 and a foot plate 260. The two bottom rods 210 are respectively fixed to the lower ends of the two steel side frames 110 by second bolts, and the base frame 220 is fixed between the two bottom rods 210 by third bolts to support the bottom of the hanging basket; the bottom plate 240 is welded to the upper surface of the base frame 220, and the two positioning members 230 are respectively installed at both ends of the bottom rods 210, and the positioning members 230 support the bottom of the box beam. The provision of the positioning members 230 can facilitate the placement of workers and goods. Not only that, when the hanging basket is installed at the joint of the box beam, by adjusting the length of the positioning member 230, the hanging basket can be in contact with the bottom of the box beam through the positioning member 230, thereby achieving the purpose of fixing the hanging basket. Clips 250 are welded to both ends of the bottom rod 210, and a foot plate 260 is provided above the bottom plate 240, which serves to protect the bottom of the hanging basket; the four corners of the foot plate 260 are installed on four clips 250, and the clips 250 are used to support the four corners of the foot plate 260, thereby increasing the stability of the installation of the foot plate 260.
[0029] The inner surface of the steel side frame 110 is welded with a first protective plate 130 and a second protective plate 140, and the protective door 150 is located between the first protective plate 130 and the second protective plate 140. The first protective plate 130 and the second protective plate 140 are used to protect the steel side frame 110.
[0030] like Figure 3 and Figure 4As shown, the protective door 150 includes a vertical support rod 151 welded to the middle of the steel side frame 110. The lower end of the vertical support rod 151 is welded to the surface of the bottom rod 210. A plurality of retaining bars 152 are movably sleeved on the outside of the vertical support rod 151. Connecting ropes 153 are installed between the retaining bars 152. Magnets 154 are bonded to the upper and lower surfaces of the retaining bars 152. In this embodiment, the protective door 150 is composed of the vertical support rod 151, retaining bars 152, connecting ropes 153, and magnets 154. The vertical support rod 151 is used to limit the position of the retaining bars 152. When the retaining bars 152 are separated, they are connected by the connecting ropes 153. When the retaining bars 152 are close to each other, they are magnetically fixed by the magnets 154, thereby achieving the purpose of expanding and contracting the protective door 150.
[0031] The magnet 154 is wrapped with a plastic sleeve on the outside and contains a magnet inside. The plastic sleeve is used to protect the magnet.
[0032] like Figure 5 As shown, the positioning member 230 includes an internally threaded sleeve 231 fixed at both ends of the bottom rod 210 by fourth bolts. A screw rod 232 is screwed onto the upper end of the internally threaded sleeve 231. The upper end of the screw rod 232 is welded with an external hexagonal column 233 and a pad 234 in sequence. The pad 234 contacts the lower surface of the box girder. By sequentially welding the external hexagonal column 233 and the pad 234 to the upper end of the screw rod 232, it is convenient to screw the external hexagonal column 233 together, so that the screw rod 232 can rise and fall within the internally threaded sleeve 231, realizing the height adjustment function of the positioning member 230. By adjusting the height of the positioning member 230, the pad 234 contacts the bottom surface of the box girder, thereby securing the hanging basket to the box girder.
[0033] like Figure 6 As shown, the clamping member 250 includes a clamping rod 251 and a clamping strip 253 welded to both ends of the bottom rod 210. One of the side ridges of the clamping rod 251 is provided with a clamping slot 252, and the clamping strip 253 is located in the clamping slot 252. This arrangement facilitates the clamping rod 251 and the clamping strip 253 to cooperate in supporting the foot plate 260, thereby increasing the stability of the foot plate 260 after installation.
[0034] The hanging lug 120 is U-shaped, which facilitates installation of the hanging lug 120 on the box girder.
[0035] This embodiment is only a further explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
