Description

A large component turning device

technical field

The utility model belongs to the technical field of hoisting, in particular to a large component overturning device.

Background technique

For some large components, in order to facilitate transportation into the site, it is often necessary to flip the components horizontally and axially by 90 degrees or 180 degrees before hoisting on site, and then hoist them to correspond to the installation orientation; To reduce upward welding as much as possible, ensure welding quality, and speed up welding progress, the component body is often turned over several times to meet the needs of the project. In the existing construction, the overturning device for large components uses a steel wire rope tied to one side of the component, the hook is lifted, the other side of the component is on the ground as a fulcrum to rotate, and the component is "tumbling". This method requires a large site and the fulcrum is limited Excessive force is very destructive to the component, and the component shakes greatly when it passes the critical state, which is unfavorable to the safety of the hoisting machinery, and this method requires a large-scale steel wire rope to bind, and the steel wire rope is relatively rigid and inconvenient to operate; another method It is hoisted by two cranes together, and the two cranes hang on both sides of the component, and the two cranes fall together to make the component turn over. Although this method is stable, it increases the mechanical cost, not to mention that some narrow construction sites cannot meet the two cranes at the same time. .

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, a large component overturning device includes a hook 1, a sling 2, a hoisting support balance beam 3, a multi-wheel block 4, a steel wire rope 5, an auxiliary small hook 7 and an auxiliary hoist There are two slings 8 and 2, and the hook 1 is a double-hook type hook. One end of the two slings 2 is respectively connected to the two ends of the hoisting support balance beam 3, and the other ends of the two slings 2 are respectively connected to the On the two hooks of the suspension hook 1, there are two multi-wheel blocks 4, and the multi-wheel block 4 is a four-wheel 32-ton block. During the overturning process of the member 6, a steel wire rope 5 is wound in series on the two multi-wheel blocks 4 respectively, and the first and last ends of the steel wire rope 5 are connected by a snap ring 9, and the middle of the steel wire rope 5 is wound around the pulley of the multi-wheel block 4 and the member 6 in turn. One end of the auxiliary sling 8 is connected to the hook of the auxiliary small hook 7 of the crane, and the other end is connected to the auxiliary hanging hole on the bottom of the component 6. The component 6 is the driving beam of the 4000-ton hydraulic lifting device, and the driving beam is high. 2 meters, 1.2 meters in width, 10 meters in length, and 26 tons in unit weight. 2 meters, according to the weight of member, multi-wheel tackle 4 can use two pulleys wherein to get final product.

The method for using the large-scale member overturning device of this embodiment comprises the following steps:

(a) the hoisting support balance beam 3 is hung on the two hooks of the suspension hook 1 of the crane by two slings 2, and two multi-wheel blocks 4 are respectively hung on the two ends of the hoisting support balance beam 3;

(b) Move the hoisting support balance beam 3 to the top of the component 6, and the vertical line of the hook 1 passes through the center of gravity of the component 6, so as to ensure that the lifted component 6 is horizontal;

(c) Then the steel wire rope 5 is wound in series, and the first pulley of the multi-wheel block 4 passes through → around the bottom of the component → the second pulley of the multi-wheel block 4 passes → around the bottom of the component → the third of the multi-wheel block 4 The two pulleys pass through..., and the first and last ends of the wire rope 5 are connected by snap rings; the second multi-wheel block is wound in 4 strings;

(d) hoisting and supporting the balance beam 3 to lift, and after the component 6 is hoisted horizontally from the ground, the auxiliary small hook 7 of the crane is connected to the auxiliary lifting hole on the bottom surface of the component 6 through the auxiliary sling 8, so that the auxiliary small hook 7 is lifted , the steel wire rope 5 that is wound in series moves evenly through the pulley, and the lifting side of the auxiliary small hook 7 is wound around the wire rope 5 to rise, and the lifting side of the component 7 rotates upwards, so that the purpose of turning over the component 7 is realized.

The advantages of the large component turning device of this embodiment:

1. Easy to operate: because the weight of the component 6 is borne by the 8 strands of steel wire ropes wound in series between the multi-wheel tackle 4 and the component 6, the steel wire ropes 5 that are wound in series can be selected with smaller specifications, and the steel wire ropes 5 of smaller specifications are more It is lighter and softer, and the hanging operation is more convenient.

2. The process is stable: in the turning device of this embodiment, the component 6 is suspended in the air, and all the weight of the component 6 is borne by the steel wire rope 5 wound in series. Contact does not form a "fulcrum", so when the member 6 turns over the critical state (that is, the center of gravity of the member 6 and the fulcrum are in a vertical plane), no shaking will occur.

3. Cost savings: This embodiment does not use an auxiliary crane to cooperate with the overturning. If an auxiliary crane is used to cooperate with the overturning, the workload is not large and the utilization rate of the machinery is low, resulting in waste of mechanical shifts and increasing construction costs.

4. Wide range of applications: the overturning device of this embodiment is not only suitable for overturning heavy steel beams, but also for overturning large steel structure frames and equipment.

The above-mentioned embodiments are only described to the preferred implementation of the utility model, and are not limited to the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the utility model.
