Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction technology, and in particular to a hanging basket gantry crane hoisting device. Background Technology

[0002] As bridge engineering develops towards larger spans and higher precision, the market has placed higher demands on construction equipment. In order to overcome the limitations of traditional hanging basket systems and improve construction efficiency and safety, existing devices have introduced a variety of structural components to enhance the overall structural stability and load distribution capabilities, effectively reducing structural damage caused by excessive local pressure. However, the existing devices, in terms of inserting steel anchor bolts, only act on the rear anchor and bridge stages, leaving a large gap in the middle without a balancing device, which may not provide sufficient stability in certain construction situations.

[0003] Therefore, in order to address the above problems, we are now developing a hanging basket gantry crane hoisting device. Utility Model Content

[0004] To overcome the shortcomings of existing devices for inserting steel anchor bolts, which only act on the rear anchor and bridge stages, leaving a large gap in the middle and lacking a balancing device, and may not provide sufficient stability in certain construction situations, this utility model provides a hanging basket gantry crane hoisting device.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] The hanging basket gantry crane hoisting device includes two diamond-shaped hangers. Each diamond hanger has three rear anchors connected to its upper front side in contact with the upper front. Fastening components, consisting of steel anchor rods and nuts, are installed on both sides of each rear anchor. A first connecting plate is rotatably connected to the lower right front side of each diamond hanger, and a second connecting plate is rotatably connected to the lower left front side of each diamond hanger. The first and second connecting plates interact with each other, and both slide against the adjacent steel anchor rods. The connection includes nuts installed on both the upper and lower sides of the first and second connecting plates, with adjacent nuts threadedly connected to the steel anchor rods. Locking bolts are threadedly connected to the inner bottom side of the front part of the diamond-shaped hanger, and each locking bolt has a limit device connected to it. Hand-operated hoists are installed on both the upper left and right sides of the diamond-shaped hanger, and handles are connected to both the upper left and right sides of the diamond-shaped hanger. Both ends of the hand-operated hoists are engaged with adjacent handles. Scissor braces are installed between the front parts of the diamond-shaped hangers, and transverse connecting trusses are installed between the rear parts of the diamond-shaped hangers.

[0007] Preferably, each of the diamond-shaped hangers has mounting holes at the rear.

[0008] Preferably, all of the rear anchors are hollow structures.

[0009] Preferably, all handles are arc-shaped.

[0010] Preferably, the scissor brace is a detachable connection structure.

[0011] Preferably, the transverse connecting truss is a hollow structure.

[0012] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model forms an interlocking mechanism through the interaction of the first connecting plate and the second connecting plate, and is fixed by nuts. This effectively disperses the construction load onto the existing bridge structure, reduces the risk caused by excessive pressure at a single point, and improves the safety and stability of the entire device.

[0014] 2. This utility model uses bolts for fixing, which simplifies the disassembly process and improves work efficiency. This design not only enhances the rigidity between the connecting plates, but also ensures the stability of the structure during construction. At the same time, it facilitates quick installation, providing convenience and safety for bridge construction. Attached Figure Description

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Hanging basket gantry crane hoisting device, such as Figures 1-4 As shown, it includes a diamond-shaped hanger 1, of which there are two. Each diamond-shaped hanger 1 has mounting holes at its rear. Three rear anchors 2 are connected to the upper front of each diamond-shaped hanger 1 in a contact manner. The rear anchors 2 are all hollow structures. Fastening components 3 are installed on both sides of each rear anchor 2. The fastening components 3 consist of steel anchor rods and nuts. A first connecting plate 4 is rotatably connected to the lower right front of each diamond-shaped hanger 1, and a second connecting plate 5 is rotatably connected to the lower left front of each diamond-shaped hanger 1. The first connecting plate 4 and the second connecting plate 5 interact with each other. Both the first connecting plate 4 and the second connecting plate 5 are slidably connected to adjacent steel anchor rods. The first connecting plate 4 and the second connecting plate 5... Nuts are installed on both the upper and lower sides of the two connecting plates 5. Adjacent nuts are threadedly connected to the steel anchor rods. Locking bolts 6 are threadedly connected to the inner bottom side of the front part of the diamond-shaped hanger 1. Limiting parts 7 are connected to the locking bolts 6. Hand-operated hoists 8 are installed on the upper left and right sides of the diamond-shaped hanger 1. Handles 9 are connected to the upper left and right sides of the diamond-shaped hanger 1. Both ends of the hand-operated hoists 8 are engaged with the adjacent handles 9. The handles 9 are all arc-shaped structures. Scissor braces 10 are installed between the front parts of the diamond-shaped hanger 1. The scissor braces 10 are detachable connection structures. A transverse connecting truss 11 is installed between the rear parts of the diamond-shaped hanger 1. The transverse connecting truss 11 is a hollow structure.

[0022] It should be noted that this device can be used during bridge construction. First, two diamond-shaped hangers 1 are installed on the completed bridge segment. The diamond structure has stability similar to a tower crane, which can distribute the construction load, much like the main support frame of scaffolding on a construction site. Then, the handles 9 are used to install the hand-operated hoists 8 on the left and right sides of the diamond-shaped hangers 1 to form a pulling force and adjust and eliminate horizontal deviations. Next, the steel anchor rods are inserted through the rear anchor 2, and simultaneously inserted through the first connecting plate 4 and the second connecting plate, connecting to the bridge segment. With the help of nuts, an upper and lower interlocking mechanism is formed, allowing the construction to proceed smoothly. The load is distributed to the existing bridge body, further increasing the stability of the device. Then, the scissor braces 10 are installed between the front parts of the diamond hangers 1 to provide longitudinal torsional resistance. The hollow transverse connecting trusses 11 are then installed at the rear of the diamond hangers 1 to reduce the weight while maintaining lateral stiffness, thus achieving the final fixing effect. When disassembling after construction, the first connecting plate 4 and the second connecting plate need to be rotated inward by 180° so that the two connecting plates fit together. Then, the locking bolt of the second connecting plate 6 is rotated downward to connect with the first connecting plate 4 and the second connecting plate by thread for fixing.

[0023] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
