[0034] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 4 The column hanging device provided in this embodiment includes a base plate 100, a hanging plate 200 and a reinforcing plate 300. The base plate 100 has a mounting surface, and the mounting surface has two long sides and two short sides. The base plate 100 is provided with connecting holes 110 extending in a direction perpendicular to the mounting surface. There are multiple connecting holes 110 and they are evenly distributed along the extending direction of the long sides on the mounting surface. The connecting holes 110 are used to connect the columns. The hanging plate 200 is arranged on the line connecting the midpoints of the two long sides. The hanging plate 200 is located on the mounting surface and fixedly connected to the base plate 100. The hanging plate 200 is perpendicular to the base plate 100. The side of the hanging plate 200 is provided with a hanging hole 210. The hanging hole 210 is located at the center of the side of the hanging plate 200. The hanging hole 210 extends along the long side and penetrates the hanging plate 200. The reinforcing plate 300 is arranged at one end of the mounting surface. The reinforcing plate 300 is located on one side of the hanging plate 200 and is fixedly connected to the hanging plate 200. The cross-section of the reinforcing plate 300 is a right triangle, and the two right-angled sides of the right triangle are respectively fixedly connected to the hanging plate 200 and the mounting surface.

[0036] Specifically, a large number of through holes are provided on the end face of the end plate column of the boiler to be lifted, and the connecting holes 110 on the bottom plate 100 are connected to the end plate column of the boiler by means of pins and bolts. After the connection between the bottom plate 100 and the end plate column of the boiler is stable, the lifting ring is connected to the lifting hole 210 on the lifting plate 200 by bolts, and the lifting ring can be lifted by using lifting equipment, or the lifting buckle can be directly inserted into the lifting ring for lifting.

[0037] It should be noted that after using the column lifting device to connect the end plate column, the lifting equipment will pull the hanger plate 200 upward during the process of lifting the column lifting device through the lifting equipment. Therefore, when connecting the column lifting device and the end plate column, the reinforcing plate 300 must be located at the lower end of the column lifting device so that the reinforcing plate 300 is located at the stress-bearing point of the hanger plate 200 to avoid tearing the lower end connection between the hanger plate 200 and the base plate 100 due to excessive pulling force when the lifting equipment lifts the hanger plate 200 upward.

[0038] Among them, in order to improve the lifting stability of the end plate column, multiple column lifting devices can be used together to connect with the lifting equipment. After multi-point connection, the weight of the end plate column is shared by multiple column lifting devices to avoid excessive force on a single column lifting device. The connection between each column lifting device and the end plate column is very stable, which can ensure that the center of gravity of the end plate column is stable after lifting. The verticality of the end plate column can be adjusted by driving the lifting equipment alone, without the need for additional tools. It is easy to install, simple in process, can improve construction efficiency, and is very safe to use.

[0039] Furthermore, the right-angled triangle reinforcing plate 300 has great structural strength and a triangular structure with strong stability, which can significantly improve the strength of the connection between the hanging plate 200 and the base plate 100 .

[0040] In addition, since the top surface of the reinforcing plate 300 is an inclined surface, the vertical space it occupies is relatively small. When using components such as lifting rings and hooks to connect with the hanging plate 200 and lift, the reinforcing plate 300 will not affect the use of the lifting rings and hooks. The space above the reinforcing plate 300 is sufficient for the lifting rings and hooks to suspend components, and the reinforcing plate 300 will not collide or squeeze with the lifting rings and hooks due to its excessive size.

[0041] In this embodiment, there are two reinforcing plates 300 , which are respectively disposed on two sides of the hanging plate 200 .

[0042] Specifically, reinforcing plates 300 are provided on both sides of the hanging plate 200, which can balance the column hanging device and keep the center of the column balancing device at the center of the base plate 100. When the column hanging device is used or moved, the column hanging device will not fall due to the different weights on both sides of the hanging plate 200, because one side is heavy and the other side is light.

[0043] In this embodiment, two reinforcing plates 300 are respectively disposed at both ends of the mounting surface in the width direction.

[0044] The two reinforcing plates 300 are respectively arranged at the two diagonal positions of the hanger plate 200 and connected to the hanger plate 200 and the base plate 100. Under this structure, when the column lifting device is used, after the column lifting device is placed flat and connected to the end plate type column, there are reinforcing plates 300 at the stress-bearing positions at the bottom ends of the hanger plate 200 and the base plate 100, which can ensure that the column lifting device can be used directly regardless of whether it is used forward or flipped 180°, without the need to specifically observe the position of the reinforcing plate 300.

[0045] In this embodiment, the bottom plate 100 , the hanging plate 200 and the reinforcing plate 300 are all steel plates.

[0046] Specifically, the base plate 100, the hanging plate 200 and the reinforcing plate 300 in this embodiment are all made of carbon structural steel, specifically Q235B steel plate.

[0047] In this embodiment, the surfaces of the bottom plate 100 , the hanging plate 200 and the reinforcing plate 300 are all provided with an anti-rust layer.

[0048] The anti-rust layer can prevent the surfaces of the base plate 100, the hanging plate 200 and the reinforcing plate 300 from rusting due to the humid environment, and prevent the base plate 100, the hanging plate 200 and the reinforcing plate 300 from deteriorating in structural stability due to rust, and from being damaged due to excessive force during use.

[0049] Specifically, in this embodiment, an anti-rust layer is formed by coating anti-rust paint on the surfaces of the base plate 100, the hanging plate 200 and the reinforcing plate 300. The anti-rust paint used in this embodiment is iron red phenolic paint.

[0050] In this embodiment, there are four connection holes 110. The four connection holes 110 are evenly arranged on the installation surface and symmetrically arranged on both sides of the hanging plate 200 with the hanging plate 200 as the symmetry axis.

[0051] The four connection holes 110 are evenly arranged on the mounting surface and symmetrically distributed with the hanging plate 200 as the symmetry axis, so that the center of gravity of the column hanging device is stable and the weight of both sides of the hanging plate 200 is the same. The more the number of connection holes 110, the more stable the connection with the end plate column.

[0052] It should be noted that the number of connection holes 110 is not limited to 2 or 4, and the number of connection holes 110 can be any even number except 0, so as to achieve a symmetrical setting with the hanging plate 200 as the symmetry axis, thereby ensuring the stability of the center of gravity of the column lifting device.

[0053] In this embodiment, the thickness of the base plate 100 and the hanging plate 200 is greater than or equal to 30 mm.

[0054] The bottom plate 100 and the hanging plate 200 are the main force-bearing structures. The greater the thickness of the bottom plate 100 and the hanging plate 200, the stronger the force-bearing capacity of the column hanging device. After many experiments, it is found that when the thickness of the bottom plate 100 and the hanging plate 200 is 30 mm, it can bear the weight of most end plate type columns. Therefore, the thickness of the bottom plate 100 and the hanging plate 200 in this embodiment is 30 mm to achieve the load-bearing function.

[0055] In this embodiment, one end of the hanging plate 200 away from the bottom plate 100 is a rounded structure.

[0056] The rounded corner structure can prevent the corners from being too sharp and scratching the surface of the workers and the end plate column. In addition, when the lifting ring is used to lift the column lifting device, it can prevent the right angle from occupying too much space and making it impossible to set the lifting ring.

[0057] In this embodiment, the column hoisting device further comprises a lifting ring and a connecting bolt. Both ends of the lifting ring are provided with screw holes. The connecting bolt is inserted into the lifting hole 210, and both ends of the connecting bolt are threadedly connected with both ends of the lifting ring.

[0058] Specifically, when in use, a connecting bolt needs to be inserted into the lifting hole 210, the middle part of the connecting bolt is placed in the lifting hole 210, and the two ends of the connecting bolt are connected to the two ends of the lifting ring through threaded matching. After connection, the lifting equipment can be used in conjunction with the wire rope to pull the lifting ring, thereby realizing the lifting of the end plate column.

[0059] In this embodiment, there are multiple base plates 100, multiple hanging plates 200, multiple reinforcing plates 300, multiple lifting rings and multiple connecting bolts. Multiple base plates 100, multiple hanging plates 200 and multiple reinforcing plates 300 are connected one-to-one to form multiple hanging seats. Multiple lifting rings, multiple connecting bolts and multiple hanging seats are arranged one-to-one.

[0060] Specifically, there are four bottom plates 100, four hanging plates 200, four reinforcing plates 300, four lifting rings and four connecting bolts, and four lifting seats are respectively arranged at the four corners of the end surface of the end plate type column, and are connected to the lifting holes 210 on the lifting seats through the lifting rings and the connecting bolts. After the four corners of the end plate type column are connected, they are lifted by the lifting equipment, and the connection is very stable.

[0061] The specifications of the hanging plate 200 in this embodiment are 150 mm long, 150 mm wide, and 30 mm thick, and the diameter of the hanging hole 210 is 40 mm. The specifications of the bottom plate 100 are 500 mm long, 150 mm wide, and 30 mm thick, and the diameter of the connecting hole 110 is 25 mm.

[0062] Furthermore, in this embodiment, the load-bearing capacity of a lifting seat is checked with 10t, the material is Q235B steel, and the plate thickness is 30mm. After looking up the table, it can be calculated that the tensile stress that the lifting seat can withstand is 220MPa, and the maximum shear force that can be sustained should be 130MPa. In this embodiment, the maximum tensile stress of the inner hole edge of the horizontal section of the lifting seat is: F / [(b-Φ)δ]=10000×9.8÷[(150-40)×30]=29.69≤[σ]=140MPa. The maximum shear stress of the lifting seat is: F / [2(h0-Φ / 2)δ]=10000×9.8÷[2×(75-20)×30]=29.69≤[σ]=80MPa. Therefore, the strength of the lifting seat meets the load-bearing and lifting requirements.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
