Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and more specifically relates to an oversized and overweight saddle hoisting device. Background Art

[0002] In the construction of modern bridges, more and more long-span bridges have gradually become a construction trend. In particular, the construction of long-span bridges of the suspension bridge and cable-stayed bridge types is also increasing. The main cable saddle of the suspension bridge is conventionally hoisted by setting a large gantry and a winch on the top of the tower as a lifting mechanism. The conventional process mainly has the following technical difficulties: 1. Due to the large deadweight of the cable saddle, a large gantry is required, and the cable saddle needs to be hoisted in blocks multiple times when necessary. 2. When hoisting the cable saddle, a larger winch and a larger pulley group need to be combined. After the pulley group has multiple lines, the hoisting speed is slow and the hoisting process is cumbersome. 2. The additional investment in gantry materials and hoisting wire ropes is large. Therefore, the existing technology cannot effectively meet the requirements.

[0003] In the prior art, there is a technology named "a main cable saddle hoisting device for the top of the main tower of a suspension bridge" and the publication number is "CN116043711A". This technology discloses a main cable saddle hoisting device for the top of the main tower of a suspension bridge, which includes a support plate, an adjustment column and a telescopic sleeve. The bottom of the support plate is fixedly connected with the adjustment column, the bottom of the adjustment column is embedded with the telescopic sleeve, the bottom of the telescopic sleeve is fixedly connected with a base, the top of the support plate is fixedly connected with a connecting plate, the top of the connecting plate is fixedly connected with a positioning connecting block, the bottom of the adjustment column is movably connected with a threaded column, the surface of the threaded column is nested with a driven wheel, the bottom of the threaded column is nested with a bearing, the left side of the driven wheel is movably connected with a driving wheel, the bottom of the driving wheel is movably connected with a lifting motor, the left side of the lifting motor is fixedly connected with a connection sensor, the inner top of the base is fixedly connected with a spring, and the bottom of the spring is movably connected with a movable disk. The present invention facilitates the device to adjust the distance and effectively improves the flexibility of the device. This technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

The super-large tower crane of the utility model can carry out the hoisting of the super-large and overweight saddle, and the saddle can be hoisted as a whole. There is no need to hoist the super-large and overweight saddle in blocks, which simplifies the construction steps, improves the hoisting efficiency, and greatly reduces the labor intensity of personnel. The good stability of the tower crane arrangement can effectively protect the construction site personnel and the construction operation is highly safe. Instead of setting up a separate gantry structure or winch structure, construction materials are saved, material costs are saved, and construction costs are reduced. The super-large and overweight saddle hoisting equipment described in the utility model has a simple structure, convenient and quick construction, reliable installation accuracy, high construction quality, reduced labor intensity of personnel, and high construction operation safety.

[0023] The cap 3 and the tower column 5 are structures made of concrete and steel bars. The above structure, the cap 3 and the tower column 5 are all components of the bridge project, ensuring the strength of the cap 3 and the tower column 5.

[0024] The tower crane 1 is a structure made of metal material. In the above structure, the tower crane can be a combination of multiple metal components on site, which is convenient for construction and the strength after combination also meets the requirements.

[0025] The tower crane 1 comprises a vertical bearing part 6 and a movable crossbeam part 7, a hoisting member 8 is arranged at one end of the movable crossbeam part 7, and a hoisting rope 9 is arranged on the hoisting member 8.

Moreover, the hoisted saddle is an extra-large and extra-heavy saddle 2.

[0030] The key innovation of the super-large and super-heavy saddle hoisting equipment described in the utility model is that a separate gantry structure or winch structure is no longer set, but a tower crane 1 is set on the pedestal 3 of the construction bridge, and the position of the tower crane 1 is set close to the tower column 5. On the one hand, during the construction of the tower column 5, the tower crane 1 can hoist materials for the construction of the tower column 5.
