Description

Technical Field

[0001] This utility model relates to the field of boiler handling technology, and in particular to an auxiliary lifting fixture. Background Technology

[0002] Before the boiler body of an industrial boiler reaches its installation location, it needs to be hoisted or moved. When installing the boiler body in some space-constrained locations, it is not possible to use a crane for hoisting operations. Ground transportation equipment is required to move the boiler body. Before moving the boiler body, it needs to be lifted so that the ground transportation equipment can support it.

[0003] In existing technologies, boilers are typically lifted using jacks. However, finding suitable lifting points beneath the boiler body is difficult, making jack installation extremely inconvenient. Furthermore, given that boilers weigh between 40 and 60 tons, improper installation of the jacks could potentially lead to boiler overturning and other serious safety accidents. Therefore, a solution to address these issues is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary lifting device to solve the problems of inconvenient lifting of the boiler body and low safety in the existing technology.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] An auxiliary lifting fixture includes a connector and a support member. Along the horizontal direction, one side of the connector is connected to the support member, and the other side is detachably connected to a boiler support leg. The lower side of the support member is connected to the movable end of a jack. The auxiliary lifting fixture also includes a reinforcing member and an auxiliary member. The reinforcing member is connected between the connector and the support member, and the auxiliary member is connected to the lower side of the support member and can abut against the lower end of the top plate of an H-beam.

[0007] Optionally, the connector has mounting holes that correspond to the positioning holes on the boiler support legs and can be connected by fasteners.

[0008] Optionally, the mounting holes are provided in multiple configurations.

[0009] Optionally, both the connector and the support member are plate-shaped, the connector extends in the vertical direction, and the thickness direction of the support member is parallel to the vertical direction.

[0010] Optionally, the reinforcing member is plate-shaped with a right-angled triangular cross-section, and the two right-angled sides of the reinforcing member are respectively attached to the connecting member and the bearing member.

[0011] Optionally, the auxiliary component includes a connecting portion extending in a vertical direction and an abutting portion extending in a horizontal direction. The upper end of the connecting portion is connected to the bearing component, and the upper end of the abutting portion can abut against the lower end of the top plate of the H-beam.

[0012] Optionally, the connecting part is connected to the side of the carrier near the boiler support leg.

[0013] Optionally, the number of reinforcing members provided is not less than two.

[0014] Optionally, the number of auxiliary components provided is not less than two.

[0015] Optionally, the connector, the load-bearing member, the reinforcing member, and the auxiliary member are all made of carbon steel.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes an auxiliary lifting fixture, including a connector and a support member. Horizontally, the support member is connected to one side of the connector, and the other side is detachably connected to a boiler support leg. The lower side of the support member is connected to the movable end of a jack. The auxiliary lifting fixture also includes a reinforcing member and an auxiliary member. The reinforcing member is connected between the connector and the support member, and the auxiliary member is connected to the lower side of the support member, and can abut against the lower end of the top plate of the H-beam.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment proposes an auxiliary lifting fixture to solve the problems of inconvenient boiler body lifting and low safety in the prior art.

[0033] like Figures 1-3 As shown, the auxiliary jacking fixture includes a connector 1 and a bearing 2. Along the horizontal direction, the bearing 2 is connected to one side of the connector 1, and the other side is used for detachable connection with the boiler support leg 200. The lower side of the bearing 2 is used for connection with the movable end of the jack. The auxiliary jacking fixture also includes a reinforcing member 3 and an auxiliary member 4. The reinforcing member 3 is connected between the connector 1 and the bearing 2, and the auxiliary member 4 is connected to the lower side of the bearing 2. The auxiliary member 4 can abut against the lower end of the top plate of the H-beam 300.

[0034] Understandably, when an industrial boiler is manufactured and shipped, four boiler legs 200 are installed on one side of the boiler body 100. Along the length of the boiler body 100, an H-beam 300 is installed under every two boiler legs 200. The boiler legs 200 are used to support the boiler body 100 on the upper side of the H-beam 300, and the lower side of the H-beam 300 rests against the ground. The boiler body 100 is generally transported to the installation location by hoisting or ground pushing. However, in some areas with large space constraints, hoisting operations cannot be carried out by crane, and ground pushing is the only option. Before the moving operation, the boiler body 100 needs to be lifted so that the ground transportation equipment can support it. However, it is difficult to find a suitable lifting point under the boiler body 100, making the installation of jacks very inconvenient. Furthermore, the boiler body 100 is quite heavy, and if the jacks are not installed properly on the boiler body 100, it is highly likely to cause a major safety accident such as the boiler body 100 overturning.

[0035] In this embodiment, a support member 2 is provided, which is connected to the boiler support leg 200 via a connector 1. The lower side of the support member 2 provides an installation position for the movable end of the jack, facilitating the lifting of the boiler body 100. A reinforcing member 3 strengthens the connection between the connector 1 and the support member 2, thereby enhancing the structural strength of the auxiliary lifting fixture and ensuring stability during the lifting of the boiler body 100. Furthermore, an auxiliary member 4 supports the top plate of the H-beam 300, further strengthening the connection between the auxiliary lifting fixture and the boiler body 100. In short, the support member 2 provides an installation position for the movable end of the jack, the reinforcing member 3 enhances the structural strength of the auxiliary lifting fixture, and the auxiliary member 4 assists in supporting the H-beam 300 on one side of the boiler body 100, facilitating the lifting of the boiler body 100 and significantly improving stability and safety during the lifting process.

[0036] It should be noted that the boiler body 100 generally has 4 boiler support legs 200. In this embodiment, the auxiliary lifting fixture is also set to 4, that is, each boiler support leg 200 is connected to an auxiliary lifting fixture.

[0037] Optionally, the connector 1 is provided with mounting holes 11, which correspond to the positioning holes on the boiler support leg 200 and can be connected by fasteners. This configuration can improve the connection efficiency between the connector 1 and the boiler support leg 200, thereby improving the lifting efficiency.

[0038] Optionally, the fastener is a bolt. Bolts have a simple structure and reliable connection strength, and the auxiliary jacking fixture can be disassembled and assembled by simply removing and installing bolts, which greatly improves the efficiency of disassembly and assembly of the auxiliary jacking fixture.

[0039] For example, the bolt is an M20 bolt of grade 12.9. This type has high tensile strength and is relatively inexpensive, improving the reliability and economy of the auxiliary lifting fixture. Of course, in other instances, bolts of other performance grades and sizes can be selected, but this is not the focus of this embodiment and will not be subject to further restrictions.

[0040] Optionally, multiple mounting holes 11 are provided. This arrangement improves the connection strength between the connector 1 and the boiler support leg 200, and enhances the reliability of the auxiliary lifting fixture.

[0041] For example, the number of mounting holes 11 is three, and the three mounting holes 11 are distributed in a triangle. This arrangement greatly improves the connection stability between the connector 1 and the boiler support leg 200, thereby improving the reliability of the auxiliary lifting tool.

[0042] It is worth mentioning that the number of mounting holes 11 can be selected as needed based on the actual situation, and there are no excessive restrictions here.

[0043] For example, the diameter of the mounting hole 11 is 10mm-30mm, preferably 18mm-22mm. This size does not compromise the structural strength of the connector 1 while ensuring sufficient connection strength. Of course, in other embodiments, other sizes of mounting hole 11 diameters can be selected, depending on the actual situation. This is not the focus of this embodiment and will not be limited here.

[0044] Optionally, both the connector 1 and the support member 2 are plate-shaped, with the connector 1 extending vertically and the thickness of the support member 2 parallel to the vertical direction. This design reduces the weight of the connector 1 and the support member 2, improving the portability of the auxiliary jacking fixture. Furthermore, this design increases the connection area between the connector 1 and the boiler support leg 200, enhancing the connection strength. In addition, the vertical arrangement of the connector 1 and the support member 2 allows for a sufficiently large mounting surface on the lower side of the support member 2, facilitating the installation of the movable end of the jack and improving the reliability of the auxiliary jacking fixture.

[0045] Optionally, the reinforcing member 3 is plate-shaped with a right-angled triangular cross-section, and the two right-angled sides of the reinforcing member 3 are respectively attached to the connecting member 1 and the bearing member 2. This arrangement not only reduces the overall weight of the reinforcing member 3, but also increases the contact length between the reinforcing member 3 and the connecting member 1 and the bearing member 2, ensuring the connection strength between the connecting member 1 and the bearing member 2, thereby improving the structural strength of the auxiliary lifting fixture.

[0046] Optionally, the auxiliary component 4 includes a connecting portion 41 extending vertically and an abutting portion 42 extending horizontally. The upper end of the connecting portion 41 is connected to the bearing component 2, and the upper end of the abutting portion 42 can abut against the lower end of the top plate of the H-beam 300. Understandably, the vertical arrangement of the connecting portion 41 and the abutting portion 42 of the auxiliary component 4 allows the abutting portion 42 to have a larger abutting surface, and the abutting surface is parallel to the top plate of the H-beam 300, which increases the abutting strength and ensures the abutting stability, thereby improving the reliability of the auxiliary lifting fixture.

[0047] Optionally, the connecting part 41 is connected to the side of the bearing member 2 near the boiler support leg 200. This arrangement makes the auxiliary part 4 closer to the boiler support leg 200 or the H-beam 300, thereby improving the installation stability of the auxiliary lifting fixture, making it less likely to fall off, and thus improving the safety during the lifting operation.

[0048] Optionally, the thickness of the plates for connector 1, bearing 2, reinforcing member 3, and auxiliary member 4 shall not be less than 20mm. This configuration can improve the overall structural strength of the auxiliary lifting fixture and enhance its reliability.

[0049] For example, the plate thickness of connector 1, bearing 2, reinforcing member 3, and auxiliary member 4 is 25mm-35mm. This configuration can improve the overall structural strength of the auxiliary lifting fixture while ensuring its portability. In other embodiments, other thicknesses can also be selected as needed, and no further restrictions are imposed here.

[0050] Optionally, the number of reinforcing members 3 is not less than two. This arrangement can improve the structural strength of the auxiliary lifting assembly by increasing the connection strength between the connecting member 1 and the bearing member 2.

[0051] For example, two reinforcing members 3 are provided, and the two reinforcing members 3 are arranged opposite each other on both sides of the bearing member 2. This arrangement enables the reinforcing members 3, the bearing member 2 and the connecting member 1 to form a frame, thereby improving the structural strength of the auxiliary lifting fixture.

[0052] Optionally, the number of auxiliary components 4 shall not be less than two. This arrangement can improve the support strength and stability of the auxiliary lifting fixture for the H-beam 300, thereby improving the lifting safety.

[0053] For example, two auxiliary components 4 are disposed opposite each other at the lower ends of the support component 2. This arrangement ensures that the two auxiliary components 4 have sufficient distance, thereby improving the support stability of the top plate of the H-beam 300 and thus improving the jacking safety.

[0054] Optionally, the connector 1, the load-bearing component 2, the reinforcing component 3, and the auxiliary component 4 are all made of carbon steel. This configuration improves the strength and corrosion resistance of the connector 1, the load-bearing component 2, the reinforcing component 3, and the auxiliary component 4, thereby enhancing the reliability of the auxiliary lifting fixture.

[0055] For example, the steel grade of connector 1, bearing 2, reinforcing member 3, and auxiliary member 4 is Q235B. This grade has high yield strength and impact toughness, which can improve the reliability and durability of the auxiliary lifting fixture.

[0056] Of course, in other embodiments, other types and grades of materials can also be selected as needed according to the actual situation, without making too many restrictions here.

[0057] The assembly process of the auxiliary lifting fixture proposed in this embodiment is as follows:

[0058] First, attach one side of the connector 1 to the boiler support leg 200, and then attach the abutting part 42 of the auxiliary part 4 to the lower end of the top plate of the H-beam 300.

[0059] Next, tighten the bolts by passing them through the mounting holes 11 on the connector 1 and the positioning holes on the boiler support 200, and align the movable end of the jack with the lower side of the support 2 and abut it.

[0060] Finally, the jacks at the four outriggers 200 are slowly raised to lift the boiler body 100 to a certain height, and the ground transport equipment is pushed to the underside of the H-beam 300. Then the jacks are lowered so that the boiler body 100 is placed on the ground transport equipment.

[0061] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
