Description

Technical Field

[0001] This invention relates to the field of lifting and hoisting equipment technology, specifically to an auxiliary mounting device for lifting power equipment and its usage method. Background Technology

[0002] In engineering fields such as steel structure installation and large equipment maintenance, hoisting power equipment is required for lifting and hoisting operations. Hoisting power equipment provides the power source and execution device for hoisting operations, and can be electric hoists, crane electric power systems, etc. For example, electric hoists are compact, operate smoothly, and are highly adaptable, making them suitable for use in numerous construction scenarios.

[0003] The size and weight of the object being lifted are often positively correlated with the selection of the lifting power equipment. When using large lifting power equipment, its excessive weight can make it impossible to manually hoist it at a height. Existing technology typically uses a crane and auxiliary lifting slings such as wire ropes. One end of the sling is attached to the crane, and the other end is attached to the hook of the lifting power equipment. After the lifting power equipment is lifted to the desired hanging height, the hook is attached to the hanging point. However, during this process, the lifting slings are prone to getting stuck in the lifting power equipment and cannot be removed, which not only increases the risks of working at height but also often requires the use of heavy machinery for extended periods, resulting in high costs.

[0004] Therefore, there is an urgent need to develop a special auxiliary mounting device that can solve the problem of the difficulty in mounting power equipment due to its excessive weight and can prevent the lifting slings from getting stuck. Summary of the Invention

[0005] In view of the above-mentioned technical situation, the present invention provides an auxiliary hanging device for hoisting power equipment, which can solve the problem that hoisting power equipment is difficult to hang at high altitudes due to its excessive weight, and can also avoid the problem of hoisting slings getting stuck.

[0006] The technical solution provided by the present invention is: an auxiliary mounting device for hoisting power equipment, which has a frame structure. The frame structure includes an upper component, a lower component, and a plurality of connecting rods located between the upper component and the lower component for connecting the upper component and the lower component. The upper component is provided with several lifting lugs for connecting the crane; The lower component is used to support the hoisting power equipment; Under the lifting action of the crane, the auxiliary mounting device rises and falls, and the lifting power equipment rises and falls accordingly under the support of the lower component, until the auxiliary mounting device rises and falls until the working lifting point for mounting the lifting power equipment is located between the upper component and the lower component.

[0007] The connection between the upper component and the connecting rod can be a fixed connection or a detachable connection.

[0008] Preferably, the connection between the lower component and the connecting rod is a detachable connection.

[0009] As one implementation, the upper-layer component has a frame structure. The frame structure includes, but is not limited to, rectangular frame structures, circular frame structures, triangular frame structures, and polygonal frame structures, with a rectangular frame structure being preferred.

[0010] Preferably, the frame structure is assembled from steel. More preferably, the steel is channel steel. Even more preferably, the frame structure is a rectangular frame structure, with the web of the channel steel having first adjustment holes arranged along its length. A first connector passes through these first adjustment holes to connect two channel steel pieces, allowing adjustment of the length and width of the rectangular frame structure. Alternatively, two channel steel pieces are first spliced ​​to form an "L" shape, and then these "L" shapes are assembled into the rectangular frame structure. The first connector is not limited and can be, for example, a bolt.

[0011] Preferably, the connecting rod is made of steel. More preferably, each connecting rod is composed of two or more connecting sub-rods. Even more preferably, a plurality of second adjustment holes are provided along the length of each connecting sub-rod. A second connector passes through these second adjustment holes to connect two connecting sub-rods, and the length of each connecting rod can be adjusted through these second adjustment holes. The second connector is not limited and can be, for example, a bolt.

[0012] Preferably, the lower component is made of steel. More preferably, the lower component comprises several support rods, each support rod having its two ends connected to the lower ends of two adjacent connecting rods. Even more preferably, one end of each support rod is detachably connected to the lower end of a connecting rod; when that end of the support rod is detached, the support rod can rotate to a vertical position around its other connecting end due to its own weight.

[0013] The lifting power equipment is not limited, including electric hoists, crane electric power systems, etc. The electric hoists include chain electric hoists, wire rope electric hoists, etc.

[0014] When the hoisting power equipment is an electric chain hoist, preferably, the support rod passes through the chain structure of the electric chain hoist.

[0015] The method for suspending hoisting power equipment at the working hoisting point using the auxiliary mounting device of the present invention is as follows: A crane and lifting slings are used, with one end of the lifting slings connected to the crane and the other end connected to the lifting lug of the auxiliary mounting device. The lifting power equipment is supported on the lower component. The crane is raised and lowered, lifting the auxiliary mounting device, and the lifting power equipment is raised and lowered accordingly under the support of the lower component, until the auxiliary mounting device is raised and lowered until the working lifting point for the lifting power equipment is located between the upper and lower components, and the lifting power equipment is mounted on the working lifting point. Then, under the action of the crane, the auxiliary mounting device is lowered, the lower component loses its support for the lifting power equipment, and the weight of the lifting power equipment is borne by the working lifting point.

[0016] Once the weight of the hoisting power equipment is borne by the working lifting point, it is preferable to disconnect the lower component from the connecting rod. This not only allows the hoisting power equipment to be suspended unobstructed from below by the working lifting point, but also allows the upper component and connecting rod to be directly separated from the hoisting power equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention employs an upper component and a lower component. The upper component is provided with a lifting lug for connecting the lifting sling, and the lower component is used to support the lifting power equipment. The working lifting point for the lifting power equipment is located between the upper component and the lower component. Therefore, the lifting lug is separated from the working lifting point, which avoids the problem in the prior art where the lifting sling is directly connected to the hook of the lifting power equipment, and the lifting sling is easily jammed by the body of the lifting power equipment and cannot be removed when the hook is attached to the working lifting point.

[0018] (2) In this invention, it is preferred to use a number of connecting rods to form a connecting rod, and the length of the connecting rod can be flexibly adjusted; it is preferred that the upper component is a frame structure and assembled from steel; it is preferred that the lower component is composed of a number of support rods; therefore, the length and width of the frame structure, the length of the support rod and the length of the connecting rod can be adjusted according to the actual size of the power equipment, so that the auxiliary hanging device is suitable for hoisting power equipment of different sizes.

[0019] (3) In this invention, the connection between the lower component and at least one of the connecting rods is preferably a detachable connection. When the hoisting power equipment is hung on the working hoisting point and the weight of the hoisting power equipment is borne by the working hoisting point, the detachable connection of the lower component can be disassembled, and the upper component and the connecting rod can be directly separated from the hoisting power equipment. There is no need for manual labor to carry out complex unhooking or disassembly operations at high altitudes, which greatly reduces the risk of high-altitude operations and improves construction efficiency.

[0020] When the lower component consists of several support rods, with each support rod having its two ends connected to the lower ends of two adjacent connecting rods, and one end of each support rod being detachably connected to the lower end of a connecting rod, after the weight of the hoisting power equipment is borne by the working lifting point, the detachable connection end of each support rod is removed. Each support rod rotates to a vertical position around its other connection end due to its own weight. This not only facilitates disassembly and simplifies the process, but also allows the support rod to be directly pulled out from the chains and other components below the hoisting power equipment, improving construction efficiency.

[0021] (4) Compared to the need to use large and expensive hoisting machinery for a long time for each hoisting operation, the auxiliary hanging device for hoisting power equipment in this invention is a reusable device that can significantly reduce the operating time of large machinery and reduce construction costs.

It should be noted that the embodiments described below are intended to facilitate the understanding of the present invention. Non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the present invention are still within the protection scope of the present invention.

[0028] In this invention, the terms "including" and "comprising" should be interpreted as including rather than exclusive or exhaustive; that is, they mean "including but not limited to".

[0029] The expressions “first,” “second,” “third,” “fourth,” etc., used in this invention can modify various constituent elements, regardless of their order and / or importance, and are only used to distinguish one constituent element from another, without limiting the corresponding constituent element.

[0030] like Figure 2 As shown, during the construction process, the hoisting power equipment 20 needs to be mounted on the working lifting point 50 of the mounting bracket 40.

[0031] like Figure 1 As shown, the auxiliary mounting device 10 of the hoisting power equipment 20 has a frame structure, including an upper component 1, a lower component 2, and several connecting rods 3 located between the upper component 1 and the lower component 2 for connecting the upper component 1 and the lower component 2. The upper component is provided with several lifting lugs 4 for connecting the crane 30. The lower component 2 is used to support the hoisting power equipment 20. Under the lifting action of the crane 30, the auxiliary mounting device 10 rises and falls, and the hoisting power equipment 20 rises and falls accordingly under the support of the lower component 2, so that the auxiliary mounting device 10 can rise and fall until the working lifting point 50 is located between the upper component 1 and the lower component 2.

[0032] In some embodiments, such as Figure 1 As shown, the upper component 1 is a rectangular frame structure assembled from steel. In some embodiments, channel steel is used as the steel.

[0033] In some embodiments, the web of each channel steel is provided with a plurality of first adjustment holes 5 arranged along the length direction. The first connector 6 passes through the first adjustment holes 5 of the two channel steels to connect the two channel steels. The length and width of the rectangular frame structure can be adjusted through these first adjustment holes 5.

[0034] In some embodiments, the rectangular frame structure is made of C12 channel steel, and a 12mm thick steel plate is welded to the upper end of the channel steel as a lifting lug 4. The first adjustment hole 5 is a round hole with a diameter of 22mm, and the first connecting piece 6 is a 10.9 grade M22 high-strength bolt.

[0035] In some embodiments, such as Figure 1 As shown, two channel steel pieces are first spliced ​​together to form an "L" shape, and then four "L" shapes are assembled to form the rectangular frame structure.

[0036] In some embodiments, such as Figure 1 As shown, the connecting rod 3 is made of steel, and each connecting rod 3 is composed of two or more connecting sub-rods 3-1 connected together.

[0037] In some embodiments, such as Figure 1 As shown, several second adjustment holes 7 are provided along the length of each connecting rod 3-1. The second connector 8 passes through the second adjustment holes 8 of the two connecting rods to connect the two connecting rods 3-1. The length of each connecting rod 3-1 can be adjusted through these second adjustment holes 7.

[0038] In some embodiments, such as Figure 1 As shown, each connecting rod 3 consists of two connecting sub-rods 3-1. Each connecting sub-rod 3-1 is made of a 12mm×100mm×600mm steel plate. Several 22mm diameter round holes are provided along the length of each connecting sub-rod 3-1. The second connecting piece 8 is a 10.9 grade M22 high-strength bolt.

[0039] The connection between the upper component 2 and the connecting rod 3 can be a fixed connection or a detachable connection.

[0040] In some embodiments, the lower component 2 is made of steel.

[0041] In some embodiments, the lower component 2 is composed of several support rods 2-1, and the two ends of each support rod 2-1 are respectively connected to the lower ends of two adjacent connecting rods 3.

[0042] In some embodiments, one end of each support rod 2-1 is detachably connected to the lower end of a connecting rod 3, for example, by a high-strength bolt connection. When the connection at this end of the support rod 2-1 is detached, the support rod 2-1 can rotate to a vertical position around the other connecting end due to its own weight, for example, the other connecting end is hinged.

[0043] In some embodiments, such as Figure 1 As shown, there are four connecting rods 3, referred to as the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod; the lower component 2 consists of two support rods, referred to as the first support rod and the second support rod; one end of the first support rod is hinged to the lower end of the first connecting rod, and the other end is bolted to the lower end of the second connecting rod. When the bolt connection is removed, the first support rod can rotate to a vertical position around the hinged end due to its own weight; one end of the second support rod is hinged to the lower end of the third connecting rod, and the other end is bolted to the lower end of the fourth connecting rod. When the bolt connection is removed, the second support rod can rotate to a vertical position around the hinged end due to its own weight.

[0044] In some embodiments, the hoisting power is a chain electric hoist.

[0045] The method for using the auxiliary mounting device 10 to mount the hoisting power equipment 20 on the working hoisting point 50 is as follows: A crane 30 is used, with one end of the crane auxiliary sling 31 connected to the crane 30 and the other end connected to the lifting lug 4 of the auxiliary hanging device. The lifting power equipment 20 is supported on the lower component 2. like Figure 3 As shown, under the lifting action of the crane 30, the auxiliary hanging device 10 is lifted and lowered, and the lifting power equipment 20 is lifted and lowered accordingly under the support of the lower component 2, until the auxiliary hanging device 10 is lifted and lowered until the working lifting point 50 of the lifting power equipment 20 is located between the upper component 1 and the lower component 2. The hoisting power equipment 20 is hung on the working hoisting point 50; then, under the action of the crane 30, the auxiliary hanging device 10 is lowered, the lower component 2 loses its support for the hoisting power equipment 20, and the weight of the hoisting power equipment 20 is borne by the working hoisting point 50. Remove the detachable connection between the lower component 2 and the connecting rod 3, so that the hoisting power equipment 20 can be suspended unobstructed from below at the working hoisting point 50.

[0046] When the lower component 2 is composed of several support rods 2-1, each support rod 2-1 is connected to the lower ends of two adjacent connecting rods 3 at both ends. Furthermore, when one end of each support rod 2-1 is detachably connected to the lower end of a connecting rod 3, and the lower component 2 loses support for the hoisting power equipment 20, the detachable connection end of each support rod 2-1 is removed, and each support rod 2-1 rotates to a vertical position around its other connection end due to its own weight. In some embodiments, when the hoisting power equipment 20 is a chain electric hoist, each support rod 2-1 passes through the chain structure of the chain electric hoist. When the support rod 2-1 rotates to a vertical position around its other connection end due to its own weight, the support rod 2-1 is directly pulled out from the chain wheel of the chain electric hoist, eliminating the need for complex unhooking or disassembly operations at height, greatly reducing the risk of high-altitude operations and improving construction efficiency.

[0047] The above embodiments provide a detailed description of the technical solution of the present invention. It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, additions, or similar substitutions made within the scope of the principles of the present invention should be included within the protection scope of the present invention.
