Description

Technical Field

[0001] The invention belongs to the technical field of lifting slings, in particular to a prefabricated sling for lifting a box-type transformer substation. Background Art

[0002] According to the power generation demand, each inverter and wind turbine is equipped with a box-type substation. In addition, with the continuous updating and transformation of urban and rural power grids, box-type substations are widely put into use.

[0003] With the widespread application of box-type substations, product functional requirements are getting higher and higher, making the conditions more and more harsh, and box-type substation products are also showing diversity. Since the transformer is the heaviest component in the internal structure, and the transformer cannot be in the middle of the box, the center of gravity of the box is biased to one side of the transformer. The hoisting equipment for hoisting the box-type substation in the prior art cannot effectively correspond to the center of gravity of the box-type substation, so the product is often shaking, unbalanced, and unstable during hoisting, or the hoisting method of two cranes and two hoists is used, which leads to difficulty in coordination, low hoisting efficiency, and increased safety hazards. In addition, in the past, sufficient operators must be equipped during the hoisting operation to command, operate, tie, and untie the ropes, which seriously increased the burden on the staff in the process and increased the total cost. Summary of the invention

[0004] In order to solve the problem that the existing lifting device cannot match the center of gravity of the box-type substation, the present invention provides a prefabricated lifting device for lifting the box-type substation.

[0005] The present invention is achieved through the following technical solutions.

[0006] A prefabricated hanger for hanging a box-type substation, comprising a first suspension beam and a second suspension beam, the second suspension beam being perpendicularly connected to the first suspension beam at one-third of its overall length, a first reinforcing rib being provided at the connection between the second suspension beam and the first suspension beam, an end of the second suspension beam away from the first suspension beam and two ends of the first suspension beam being respectively connected to second reinforcing ribs, the first suspension beam, the second suspension beam and two second reinforcing ribs forming a hanging plate, a hanging plate being provided at one end of the second suspension beam away from the first suspension beam and both ends of the first suspension beam, the hanging plate being connected to a first shackle via an upper hanging rope, the first shackle being provided just above the center of gravity of the hanging plate, a lower hanging rope extending downwardly being provided on the hanging plate, and two lower hanging ropes being provided on the hanging plate at the end of the second suspension beam. The first suspension beam cooperates with the second suspension beam to adjust the center of gravity of the hanging plate. The first shackle above the center of gravity of the hanging plate achieves the balance of the hanging plate through the upper lifting rope, so as to smoothly lift the box-type substation with an irregular center of gravity; the structural strength of the welding point of the first suspension beam and the second suspension beam is increased by the first reinforcement rib, and the structural strength of the first suspension beam and the second suspension beam is improved by the second reinforcement rib.

[0007] A further improvement of the present invention is that the hanging plates on both ends of the first suspension beam are welded between the first suspension beam and the second reinforcement rib, and the hanging plates on the ends of the second suspension beam are fixed to the connection between the two second reinforcement ribs and the second suspension beam by welding. The hanging plates are welded between the suspension beam and the second reinforcement rib or at the connection between the suspension beam and the second reinforcement rib to improve the firmness of the hanging plates on the suspension plate, and at the same time, the structural connection strength between the suspension beam and the second reinforcement rib can also be improved.

[0008] A further improvement of the present invention is that the hanging plate is in the shape of a vertical isosceles triangle, the top corner of the hanging plate is arranged above the hanging plate, and the top corner of the hanging plate is provided with an upper through hole, and the second shackle connected to the upper sling is arranged in the upper through hole, and the bottom edge of the hanging plate is arranged below the hanging plate, and the bottom edge of the hanging plate is provided with a lower through hole, and the third shackle connected to the lower sling is arranged in the lower through hole. The triangular hanging plate ensures structural stability, and is connected to the second shackle and the third shackle through the upper through hole and the lower through hole, respectively.

[0009] A further improvement of the present invention is that the number of the lower through holes is at least two and they are evenly distributed along the bottom edge of the hanging plate. When the plurality of lower through holes are evenly distributed on the bottom edge of the hanging plate, the third shackle is hung in a suitable lower through hole during hoisting to supplement the balance.

[0010] A further improvement of the present invention is that the first suspension beam, the second suspension beam and the two second reinforcement ribs are all channel steels with openings facing upward, and channel steel reinforcement ribs are arranged inside the grooves of the channel steels. The structural strength of the hanging plate is increased by the channel steels and the channel steel reinforcement ribs inside the channel steels.

[0011] A further improvement of the present invention is that the first reinforcing rib is a triangular plate horizontally connected and fixed between the first suspension beam and the second suspension beam, and the structural strength of the connection point between the first suspension beam and the second suspension beam is increased by the first reinforcing rib of the triangular plate.

[0012] A further improvement of the present invention is that the upper sling and the lower sling are both steel wire ropes, which are selected to meet the required load-bearing capacity.

[0013] A further improvement of the present invention is that a box-type substation is provided below the above-mentioned hanging plate, the box-type substation is hung at the lower end of the lower hanging rope, and the center of gravity of the box-type substation is on the same vertical line as the first shackle. By adjusting the center of gravity of the first shackle and the hanging plate to correspond to the center of gravity of the box-type substation, the stability during hanging is improved.

[0014] It can be seen from the above technical scheme that the beneficial effects of the present invention are: the first suspension beam and the second suspension beam are cooperated to realize the adjustment of the center of gravity of the hanging plate, and the first shackle above the center of gravity of the hanging plate is used to balance the hanging plate through the upper lifting rope, so as to smoothly lift the box-type substation with an irregular center of gravity; the structural strength of the welding point of the first suspension beam and the second suspension beam is increased by the first reinforcement rib, and the structural strength of the first suspension beam and the second suspension beam is improved by the second reinforcement rib.
