Description

A magnetic lifting device suitable for steel plates of different sizes

technical field

The utility model relates to a lifting device, in particular to a magnetic lifting device suitable for steel plates of different sizes.

Background technique

The wind tower is welded by multiple tower tubes and flanges. After welding, the heavy-duty wind tower can reach a cylindrical structure with a length of 16-26m. The tower tube is rolled from a large steel plate. The wind tower tube is the most The diameter of the next section can reach 5 meters, and the diameter of the top section can reach about 2 meters. Each section weighs dozens of tons. Therefore, the steel plate used to make the tower is large in size and heavy in weight, requiring corresponding lifting devices for handling. The most basic requirements of mobile cranes are stable, accurate, fast, safe and reasonable. With the continuous development of industry and machinery, progress has been made in all aspects, but safety is still the most important requirement in mobile cranes. Safety awareness, and more importantly, the operation safety of mobile crane equipment, this is an area that needs to be further improved in the industry. Due to the different sizes of steel plates, electromagnets of different sizes are required for adsorption and lifting in order to ensure the safety of mobile cranes. And one is that the length is not enough for its safety performance; the larger the electromagnet is, the heavier the quality is, and the cost is high.

Utility model content

Aiming at the above-mentioned problems in the prior art, the utility model is to provide a magnetic lifting device suitable for steel plates of different sizes, which can effectively solve the above-mentioned problems in the prior art.

The technical scheme of the utility model is:

A magnetic lifting device suitable for steel plates of different sizes, including two electromagnets with the same structure, corresponding positioning seats are arranged on the opposite sides of the electromagnets, and a drawer is arranged between the electromagnets by connecting between the positioning seats. pull the sleeve rod; above the electromagnet, there are corresponding double-ear ring seats, and the double-ear ring seats are hinged with corresponding pull rods, and the pull rods are not hinged to the double-ear ring seats. The other ends are connected to each other and are all connected to the three-ear hanger; one end of the three-ear hanger is provided with a lifting hole for connecting the lifting device, and the other end is provided with three hinged holes with the same structure at equal intervals.

The two-ear ring seat is obliquely fixedly connected above the electromagnet.

The first steel ball latch is hingedly arranged between the double ear ring seat and the pulling rod.

The second steel ball latch is hingedly arranged between the pulling rod and the three-ear hanger.

Advantage of the utility model:

The utility model has a wide application range, and can be used for crane transportation of steel plates of different sizes, thereby reducing equipment cost investment. The triangular stable structure is formed by two pull rods connected to the electromagnet and the pull sleeve rod to ensure the stable performance of the magnetic lifting device, and it can be flexibly adjusted to improve the range of use.

Detailed ways

For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail with the embodiment in conjunction with the accompanying drawings:

Referring to Figure 1-2, a magnetic lifting device suitable for steel plates of different sizes includes two electromagnets 1 with the same structure, and corresponding positioning seats 2 are provided on the opposite sides of the electromagnets 1, and the electromagnets 1 There is a pull sleeve rod 3 connected between the positioning seats 2; the corresponding two-ear ring seat 4 is obliquely fixed directly above the electromagnet 1, and the two-ear ring seat 4 of the two-ear ring seat 4 is hinged. There is a corresponding pulling rod 5, the other ends of the unhinged two-ear ring seat 4 of the pulling rod 5 are connected to each other, and are all connected to the three-ear hanging part 6; Lifting holes 61, the other end is provided with three hinged holes 62 with the same structure at equal intervals; the double-ear ring seat 4 and the pulling rod 5 are hinged by setting the first steel ball pin (not marked), and the pulling rod 5 It is hingedly set with the three-lug hanger 6 by setting the second steel ball latch (not marked).

According to the size of the steel plate to be hoisted and transported, adjust the length of the puller rod 3 so that the electromagnet 1 is located at both ends of the steel plate as much as possible to ensure that the two ends are completely absorbed before hoisting, which can improve the hoisting of the steel plate Process security and cost savings.

The above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
