Abstract

The invention relates to the field of large refrigerating unit transportation, in particular to a convenient in-place method for a large refrigerating unit. The method comprises the steps that S1, a lifting device is prepared, and a ground tank is placed below supporting legs of the refrigerating unit; S2, the height of the refrigerating unit is lowered, and each supporting leg of the refrigerating unit is correspondingly placed on the ground tank; S3, the refrigerating unit is dragged and consigned to the position near a refrigerating unit foundation table; S4, the refrigerating unit is lifted to exceed the foundation table through a chain block fixed to a floor, and the ground tank on the supporting legs, away from the foundation table, of the refrigerating unit is disassembled; S5, a supporting tool is prepared, the disassembled ground tank is fixed to one end of the supporting tool, and the other end of the supporting tool is connected to the supporting legs of the refrigerating unit; S6, the refrigerating unit is dragged to be roughly in place on the foundation table; S7, sizing blocks are arranged, and alignment and leveling are conducted; and S8, the chain block is taken down, tools and the site are arranged, and finished product protection is well achieved. The design concept is ingenious, in-place installation of the large refrigerating unit can be rapidly completed, and the method is suitable for wide application and popularization.

Example Embodiment

[0032]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033]SeeFigure 1 to Figure 3The present invention provides a convenient method for large-scale refrigeration unit to be placed in place, without changing the original handling method, reducing the number of times that the floor slab is drilled and fixed at different positions during two liftings, and only needs to be fixed and removed once, while reducing Labor and time costs also improve installation efficiency. It includes the following steps:

[0034]S1. Prepare a lifting device to lift the refrigeration unit to a certain height; place the ground tank under the legs of the refrigeration unit;

[0035]S2. Lower the height of the refrigeration unit, place each leg of the refrigeration unit on the ground tank correspondingly, and fix the connection by bolts;

[0036]S3. Drag the refrigeration unit and consign it to the base of the refrigeration unit;

[0037]S4. Lift the refrigeration unit beyond the base platform by using the fixed inverted chain on the floor, and disassemble the ground tank on the leg of the refrigeration unit away from the base platform.

[0038]S5. Prepare a support tool, fix the disassembled ground tank to one end of the support tool, and connect the other end of the support tool to the leg of the refrigeration unit.

[0039]S6. Drag the refrigeration unit roughly in place on the foundation table;

[0040]S7. Lift the refrigeration unit through the fixed reverse chain on the floor, take out the ground tank, fine-tune the unit to the predetermined position, set the horn, and level it;

[0041]S8. Remove the inverted chain, organize the tools and site, and protect the finished product.

[0042]In the S1, the lifting device is a door-type hoisting frame, and a reverse chain for lifting the refrigeration unit is installed on the door-type hoisting frame.

[0043]There are four ground tanks, which are respectively fixed under the four legs of the refrigeration unit.

[0044]In the S4, the inverted chain fixed on the floor is used to lift the refrigeration unit to a distance of 15-20 cm beyond the base station.

[0045]The supporting tool is welded by channel steel. Two supporting tools are provided. A through hole is provided above the supporting tool, and the through hole is connected and fixed with the refrigeration unit.

[0046]In the S1, the weight of the inverted chain is at least 5T.

[0047]Triangular brackets are respectively installed on both sides of the door-shaped lifting frame.

[0048]During the towing process of the refrigeration unit, the position and orientation of the unit should be adjusted to ensure that the unit centerline coincides with the longitudinal centerline of the foundation.

[0049]Before placing the tank wheels, clean up the garbage on the ground, mainly floating ash, floating soil, gravel, etc., and expose the concrete ground.

[0050]Production of tools involved in the present invention

[0051]1. Small tools and equipment: 4 5T reverse chains, 4 ground tank wheels;

[0052]2. Raw materials: 12# channel steel: 2000mm, 10# channel steel: 5000mm, DN80 welded pipe: 8600mm, DN40 galvanized steel pipe: 4000mm, 4 5T inverted chains, 4 ground tanks, bolt 22#: 4, φ10 Smooth round steel bars 2000mm.

[0053]3. Processing steps

[0054]1) Cut the DN80 welded pipe into 3 sections with lengths of 3 meters, 2.8 meters and 2.8 meters, and weld them into a gate shape;

[0055]2) Cut the DN40 galvanized steel pipe into 1 meter long 4 sections, 12# channel steel cut 1 meter long two sections, pressFigure 4 For welding of the size shown, the cutting seam is required to be flat and smooth;

[0056]3) The 10# channel steel is 0.3 m (2 at the upper level, 2 at the middle isolation) in 4 sections, 0.52 m (level of the base), 3 sections, 0.56 m (vertical), 2 sectionsFigure 5 Cut to the size shown and welded to polish the burrs;

[0057]4) Punch the middle part of the upper channel steel hydraulically, and the hole diameter is consistent with the size and position of the bolt hole at the bottom of the unit;

[0058]5) Place two ground tank wheels under the channel steel at the bottom, and place the other two on the foundation to connect with the other two legs of the unit.

[0059]Only the preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present invention. Such changes and various changes should be included in the protection scope of the present invention.
