Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting tools, and in particular relates to a narrow-screen-spacing serpentine tube screen hoisting tool. Background Art

[0002] As a key component of heat exchange equipment, the manufacturing and assembly quality of the serpentine tube screen directly affects the performance of the product. As heat exchange equipment gradually develops towards high parameters and large capacity, the size of the serpentine tube screen is getting larger and larger, and the spacing between the tube screens is getting smaller and smaller, and the manufacturing difficulty of the product is gradually increasing. The two ends of the serpentine tube are generally connected to the header, and are often manufactured by assembling the header vertically, which puts forward higher requirements on the overall flatness and deformation of the serpentine tube; the overall rigidity of the serpentine tube screen is poor after the size becomes larger, and the deformation is more obvious during the lifting and transportation process. The traditional method generally uses multiple lifting points on the lifting beam, and uses slings or wire ropes to tie them up for overall lifting. Although this method can ensure that the tube screen will not be deformed after lifting, it has the following problems for tube screens with smaller screen spacing: 1) The screen spacing is too small, so that the tube screen cannot be lowered to the specified gap position and cannot be hoisted in place; 2) Due to the small screen spacing, it is difficult to remove the wire rope or sling after hoisting in place; 3) The operation is cumbersome. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a narrow screen spacing serpentine tube panel lifting tooling, which not only ensures that the tube panel will not be deformed during the lifting process, but also solves the problem that the screen spacing is small and the lifting tool cannot be removed after the tube panel is lifted into place, and the tooling is relatively simple to manufacture and use.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0026] Example

[0027] Please refer to Figure 1-6 The present embodiment provides a narrow screen spacing serpentine tube panel hoisting tool, which includes a hanging beam 1 with a lifting ear 2 and a pin 3 for limiting the serpentine tube panel 4, and the pin 3 is an L-shaped structure to prevent the pin 3 from detaching from the hanging beam 1. The hanging beam 1 is provided with a U-shaped groove for supporting the tube panel. The hanging beam 1 can be a structure composed of a vertical plate, a top plate and a bottom plate, that is, the top plate and the bottom plate are respectively welded on both sides of the vertical plate to form a U-shaped groove. The hanging beam 1 can also be made of channel steel. The hanging beam 1 in the present embodiment uses channel steel to support the serpentine tube panel 4. In order to strengthen the hanging beam 1, the present embodiment has a plurality of reinforcing ribs 11 welded in the U-shaped groove of the hanging beam 1. At the same time, at least one reinforcing rib 11 is welded in the U-shaped groove below the position of the lifting ear 2 to increase the strength of the lifting point.

[0028] In this embodiment, a plurality of insertion holes are provided on the hanging beam 1. Specifically, through holes are drilled on the wall plates on the upper and lower sides of the channel steel. When in use, the pins 3 sequentially penetrate the through holes of the channel walls on both sides of the channel steel. It should be noted that when the hanging beam 1 adopts a structure consisting of a vertical plate, a top plate and a bottom plate, the insertion holes are provided on the top plate and the bottom plate.

[0029] When the present embodiment is used, the pin 3 is passed through the two groove walls of the suspension beam 1 and the pin 3 is located in the elbow area of ​​the serpentine tube panel, which plays a role in limiting the position of the serpentine tube panel 4 during the lifting process. Figure 1 and 2 As shown, the elbow area of ​​the serpentine tube panel refers to the area surrounded by the arc tubes on both sides of the serpentine tube panel that are in contact with the suspension beam 1.

[0030] The hoisting method of the serpentine tube panel 4 in this embodiment is:

[0031] (1) Wood planks 5 are used to support both sides of the serpentine tube panel 4, and the wood planks 5 must avoid the elbow area;

[0032] (2) Use a crane to lift two hanging beams 1 to the placement area of ​​the serpentine tube panel 4;

[0033] (2) The two hanging beams 1 are respectively clamped in the elbow areas on both sides of the serpentine tube panel 4, and the positions of the hanging beams 1 are adjusted to ensure that the elbow areas on both sides of the serpentine tube panel 4 are aligned with the insertion holes of the hanging beams 1;

[0034] (3) Insert the pin 3 to limit the serpentine tube panel 4 to the U-shaped groove of the suspension beam 1;

[0035] (4) Use a wire rope to connect the crane to the lifting lug 2 and then lift it;

[0036] (5) After the serpentine tube panel 4 is hoisted to the designated position by a crane, the latch 3 is removed;

[0037] (6) Use a crane to lift the tooling away from the serpentine tube panel 4.

[0038] It should be noted that the wooden square 5 refers to a strip of wood used to support the serpentine tube panel 4. This embodiment uses the latch 3 for positioning, which is convenient and quick, and solves the problem in the prior art that the lifting device cannot be removed after the tube panel is hoisted in place.

[0039] In this embodiment, the U-shaped groove of the hanging beam 1 is used to support the tube panel as a whole, and the pin shaft is used to limit the bending part of the tube panel on the channel steel, which not only ensures that the tube panel will not be deformed during the lifting process, but also solves the problem that the panel spacing is small and the lifting tool cannot be removed after the tube panel is lifted in place. The tooling manufacturing and operation are relatively simple.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
