Description

Technical Field

[0001] This utility model relates to the field of motor hoisting technology, and in particular to a medium and large motor hoisting device. Background Technology

[0002] The usual method for hoisting a motor involves setting one or two mounting threaded holes on the motor body and using standard lifting rings for lifting. This is often done horizontally using the tensile strength of the lifting ring threads. However, when vertical installation or disassembly is required, lifting holes must be set in the opposite direction. Hoisting a motor is time-consuming and labor-intensive, and the lifting rings are subjected to shearing forces during hoisting, which often poses a risk of breakage.

[0003] Existing motor lifting methods can only achieve horizontal lifting, which is inconvenient for installation and maintenance. Furthermore, due to the weight of medium and large motors, the lifting rings are subject to shear forces during lifting, reducing lifting safety. To facilitate lifting, installation, and disassembly, portable lifting devices must be installed to effectively utilize space and improve both lifting efficiency and safety.

[0004] Based on this, the present invention provides a safe and efficient hoisting structure for installing and disassembling medium and large motors in the horizontal and vertical directions. Utility Model Content

[0005] Based on the above analysis, this utility model aims to provide a medium and large motor lifting device to solve one of the problems of existing lifting methods, such as single lifting direction, low lifting efficiency, and low lifting safety.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] A medium-to-large-sized motor lifting device includes: a first lifting positioning plate and a second lifting positioning plate fixedly installed on the motor body; the first lifting positioning plate is provided with a first lifting hole; the second lifting positioning plate is provided with a second lifting hole and a third lifting hole; the first lifting hole and the second lifting hole are located on the same plane and are used to install lifting rings to achieve horizontal lifting of the motor body; the second lifting hole and the third lifting hole are located on the same plane, and the third lifting hole is offset from the first lifting hole, and the second lifting hole and the third lifting hole cooperate to achieve vertical lifting of the motor body.

[0008] Furthermore, the first hoisting positioning plate is a Z-shaped reinforcing plate, and two Z-shaped reinforcing plates are symmetrically installed on both sides of the motor body.

[0009] Furthermore, the lower end of the Z-shaped reinforcing plate is provided with a first mounting hole, which can be fixedly connected to the motor body by screws.

[0010] Furthermore, the upper end of the Z-shaped reinforcing plate is provided with a first hoisting hole.

[0011] Furthermore, the Z-shaped reinforcing plate has a bending structure in the middle, which is used to avoid the mounting holes on the motor body flange.

[0012] Furthermore, the second hoisting positioning plate is an L-shaped fixing plate, and two L-shaped fixing plates are symmetrically installed on both sides of the motor body.

[0013] Furthermore, the L-shaped fixing plate has a second mounting hole in the middle, which can be fixedly connected to the motor body by screws.

[0014] Furthermore, a second lifting hole is provided at one end of the L-shaped fixing plate, and a third lifting hole is provided at the other end of the L-shaped fixing plate.

[0015] Furthermore, the plane containing the plurality of first and second lifting holes is parallel to the axis of the motor body.

[0016] Furthermore, the plane containing the plurality of second and third lifting holes is set at an acute angle to the plane containing the first and second lifting holes.

[0017] The technical solution of this utility model can achieve at least one of the following effects:

[0018] 1. The medium and large motor lifting device of this utility model can realize the horizontal and vertical lifting of medium and large motors. Horizontal lifting is achieved through the coordinated cooperation of the first and second lifting holes. During horizontal lifting, the motor axis is perpendicular to the direction of the lifting force, reducing swaying and lifting shear force. The staggered arrangement of the second and third lifting holes forms a vertical lifting point, enabling the motor to be lifted vertically. This facilitates the convenient installation, disassembly, and maintenance of medium and large motors, meets the installation requirements under different working conditions, and improves the flexibility and efficiency of lifting operations.

[0019] 2. The lifting device for medium and large motors of this utility model can be made of high-strength metal materials for both the Z-shaped reinforcing plate and the L-shaped fixing plate. The structure is solid and the bending design does not interfere with the original installation interface of the motor. It is suitable for universal lifting operations of medium and large motors of various specifications.

[0020] 3. The medium and large motor lifting device of this utility model, through the positional layout and structural design of the lifting holes on the Z-shaped reinforcing plate and L-shaped fixing plate, sets the first and second lifting holes on the same plane, and offsets the third lifting hole, realizing multi-point bidirectional lifting. This can effectively disperse the stress concentration during the lifting process and the shear force generated by the motor's own weight on the lifting ring during lifting, thereby improving the overall lifting safety and structural durability. At the same time, the symmetrical arrangement of the positioning plates makes the force more balanced, further reducing the risk of tilting and falling off caused by uneven loading during the lifting process, and ensuring the smooth lifting of the motor after hoisting.

[0021] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the description and accompanying drawings, which are particularly pointed out. Attached Figure Description

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Example 1

[0028] A specific embodiment of this utility model discloses a lifting device for medium and large motors, such as... Figure 1As shown, it includes: a first lifting positioning plate and a second lifting positioning plate fixedly installed on the motor body 3; the first lifting positioning plate is provided with a first lifting hole 4; the second lifting positioning plate is provided with a second lifting hole 7 and a third lifting hole 8; the first lifting hole 4 and the second lifting hole 7 are located on the same plane and are used to install lifting rings to achieve horizontal lifting of the motor body 3; the second lifting hole 7 and the third lifting hole 8 are located on the same plane, and the third lifting hole 8 is offset from the first lifting hole 4, and the second lifting hole 7 and the third lifting hole 8 cooperate to achieve vertical lifting of the motor body 3.

[0029] The first lifting positioning plate is a Z-shaped reinforcing plate 1, and the second lifting positioning plate is an L-shaped fixing plate 5. The lower part of the two front Z-shaped reinforcing plates 1 is provided with four mounting holes 2, which are fixed to the motor body 3 on both sides by four internal hexagon head screws, serving as a fixed support. The first lifting hole 4 and the second lifting hole 7 cooperate to perform horizontal lifting; the third lifting hole 8 and the second lifting hole 7 form a vertical lifting cooperation. That is to say, when the second lifting hole 7 cooperates with the first lifting hole 4, it serves to perform horizontal lifting of the motor body 3, and when the second lifting hole 7 cooperates with the third lifting hole 8, it serves to perform vertical lifting of the motor body 3.

[0030] Furthermore, such as Figure 1 As shown, two Z-shaped reinforcing plates 1 are symmetrically installed on both sides of the motor body 3. The lower end of each Z-shaped reinforcing plate 1 has a first mounting hole 2, which allows it to be fixedly connected to the motor body 3 using screws. Specifically, each Z-shaped reinforcing plate 1 has four first mounting holes 2.

[0031] Specifically, the upper end of the Z-shaped reinforcing plate 1 is provided with a first lifting hole 4. The first lifting hole 4 is located at the top of the Z-shaped reinforcing plate 1, which facilitates the stable lifting of the motor body 3 in conjunction with a lifting device.

[0032] Furthermore, the Z-shaped reinforcing plate 1 has a bending structure in the middle, which is used to avoid the mounting holes on the flange of the motor body 3. For example, as shown... Figure 1 As shown, the bending structure consists of two consecutive 90° bends.

[0033] Preferably, the folded structure has an arc-shaped transition, which not only ensures the structural strength of the Z-shaped reinforcing plate, but also allows it to be misaligned with the bolt connection holes at the flange of the motor body 3, thus reserving space for flange installation.

[0034] like Figure 1 As shown, two L-shaped fixing plates 5 are symmetrically installed on both sides of the motor body 3. Figure 1As shown, the turning point of the L-shaped fixing plate 5 is connected to the motor body 3 through the second mounting hole 6; the vertical section of the L-shaped fixing plate 5 is provided with a second lifting hole 7, and the horizontal section is provided with a third lifting hole 8. The two sets of second lifting holes 7 and third lifting holes 8 work together to realize the vertical lifting of the motor body 3, and the multi-lifting point design is used to improve the force balance during vertical lifting.

[0035] Furthermore, the L-shaped fixing plate 5 is provided with a plurality of second mounting holes 6 in the middle, and the threaded holes corresponding to the second mounting holes 6 enable the L-shaped fixing plate to be fixedly connected to the motor body 3 by screws.

[0036] Furthermore, a second lifting hole 7 is provided at one end of the L-shaped fixing plate 5, and a third lifting hole 8 is provided at the other end of the L-shaped fixing plate 5. The four second mounting holes 6 at the lower part of the two rear L-shaped fixing plates 5 are fixed to the motor body 3 on both sides of the motor body 3 with four hexagon socket head cap screws, which serve as a fixed support.

[0037] In practice, the plane containing the plurality of first lifting holes 4 and second lifting holes 7 is parallel to the axis of the motor body 3. The plane containing the plurality of second lifting holes 7 and third lifting holes 8 is set at an acute angle to the plane containing the first lifting holes 4 and second lifting holes 7. This utility model reduces the risk of off-center load through the coordinated cooperation of the Z-shaped reinforcing plate 1 and the L-shaped fixing plate 5, realizes rapid switching between horizontal and vertical lifting conditions, and improves assembly efficiency.

[0038] The difference between this utility model's medium and large motor lifting device and traditional lifting rings lies in its use of a multi-directional lifting mode. This allows it to be lifted horizontally during horizontal assembly and debugging, and vertically during on-site assembly and disassembly. It is convenient to use and can make full use of the space arrangement of the motor itself to achieve the convenience of multi-directional lifting.

[0039] The medium and large motor lifting device of this utility model can achieve stable lifting of the motor body 3 in two directions by using the Z-shaped reinforcing plate 1 and the L-shaped fixing plate 5, reducing the risk of the motor body falling during the lifting process due to shear force during non-axial lifting. The structure is simple and compact, and easy to install, disassemble and maintain.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
