Technical Field

[0001] The utility model relates to the technical field of fan transportation, and more specifically, to a long-distance transportation fan impeller damage prevention bracket. Background Art

[0002] As market competition becomes increasingly fierce and customers have more and more diversified export projects, more and more fan equipment needs to be transported over long distances. During transportation, the weight of the impeller is relatively large. Usually, bearings are precision parts and are usually installed in advance to avoid the trouble of secondary installation for customers. However, long-distance transportation can easily cause damage to the bearings.

[0003] At present, there is no information about bearing damage during long-distance transportation of fan impellers, whether domestically or internationally, and there is no better protective measure in this area. Utility Model Content

[0004] In view of this problem in practical application, the utility model aims to propose a long-distance transport fan impeller damage prevention bracket to avoid bearing damage during long-distance transportation. The specific scheme is as follows:

[0005] A long-distance transport fan impeller anti-damage bracket comprises a top block, a vertical bracket and a transverse bracket, the vertical bracket is fixed to the top of the transverse bracket, the top block is fixed to the top of the vertical bracket, the top block is used to support the impeller, and the shape of the top supporting surface of the top block is adapted to the shape of the impeller, the transverse bracket is provided with fasteners, and the transverse bracket is fixed to the fixed surface via the fasteners.

[0006] Furthermore, the transverse support is a transversely placed channel steel, and a side closing plate is fixed to one side of the channel steel.

[0007] Furthermore, at least one side mounting hole is formed on the side closing plate, and the fastener passes through the side mounting hole to connect the transverse bracket and the fixing surface.

[0008] Furthermore, the vertical support is a vertically placed channel steel, and a top closing plate is fixed on the top of the channel steel.

[0009] Furthermore, a central mounting hole is provided at the center of the top closing plate.

[0012] The lifting member comprises a stud and at least one nut, wherein the stud passes through the central mounting hole from bottom to top until the top block is fixed thereto, and the nut is spirally connected to the stud and locks the stud on the vertical bracket.

[0013] Furthermore, the top block is made of aluminum.

[0014] Furthermore, the horizontal support and the vertical support are made of steel sections and are welded together.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] like Figure 1 As shown, a long-distance transport fan impeller damage prevention bracket includes a top block 1, a vertical bracket 2 and a transverse bracket 3. The vertical bracket 2 is fixed on the top of the transverse bracket 3. The top block 1 is fixed on the top of the vertical bracket 2. The top block 1 is used to support the impeller 100, specifically, it is supported on the main shaft 200 of the impeller 100, and the shape of the top support surface of the top block 1 is compatible with the shape of the main shaft 200. The transverse bracket 3 is provided with a fastener 4. The transverse bracket 3 is fixed to the fixed surface 300 through the fastener 4. The fixed surface 300 can be one of the side surfaces of the supporting component supporting the fan impeller 100 as a whole. Its structure is not repeated here. When using the damage prevention bracket of this embodiment, by fixing the damage prevention bracket as a whole on the fixed surface 300, and supporting the main shaft 200 of the impeller 100 by the top block 1, the impeller 100 can be prevented from rotating during transportation, thereby avoiding bearing damage.

[0029] Specifically, combined Figure 2-5 The top of the top block 1 tilts downward from both sides to the center to form a V-shaped concave portion, see Figure 5 , and the angle of the V-shaped recess is 145°. When the top block 1 supports the main shaft 200, the main shaft 200 is located in the V-shaped recess, achieving support stability.

[0030] The top block 1 is made of aluminum, which is soft and not easy to damage the main shaft 200, and the aluminum structure is easy to process.

[0031] See Figure 2-3 The transverse support 3 is a transversely placed channel steel, and a side closing plate 5 is fixed to one side of the channel steel. Preferably, the side closing plate 5 and the channel steel can be fixed by welding or screw connection.

[0032] At least one side mounting hole 6 is provided on the side closing plate 5, preferably two in the present embodiment, each side mounting hole 6 corresponds to a fastener 4, the fastener 4 can be a screw, a bolt or other component, a corresponding hole is preset on the fixing surface 300, the fastener 4 passes through the side mounting hole 6 and the corresponding hole to connect the transverse bracket 3 and the fixing surface 300.

[0033] In addition, according to the size of the impeller 100, the position of the preset corresponding hole on the fixing surface 300 can be adjusted so that the top block 1 can just support the main shaft 200 of the impeller 100, so that the anti-damage bracket can adapt to impellers 100 of different sizes.

[0034] The vertical support 2 is a vertically placed channel steel, the bottom of which is fixed to the top of the horizontal support 3, and the top of the channel steel is fixed with a top closing plate 7. Preferably, the top closing plate 7 is fixed to the channel steel by welding or screw connection.

[0035] The horizontal support 3 and the vertical support 2 are both made of steel sections, and the fixing method between the two is preferably welding.

[0036] In addition to changing the position of the corresponding hole preset in the fixing surface 300 to change the height of the top block 1, the anti-damage bracket of this embodiment further includes a lifting member 8, through which the height of the top block 1 is adjusted. The top block 1 is connected to the vertical bracket 2 via the lifting member 8, which is used to drive the top block 1 to rise and fall.

[0037] Specifically, the lifting member 8 includes a stud 81 and at least one nut 82, preferably three nuts 82 in this embodiment, a central mounting hole (not shown in the figure) is provided in the center of the top closing plate 7, a slot (not shown in the figure) is provided at the bottom of the top block 1, and the stud 81 passes through the central mounting hole from bottom to top along a direction perpendicular to the vertical bracket 2 until it extends into the slot of the top block 1 and is screwed to the top block 1, and the three nuts 82 are all screwed to the stud 81, two of which are respectively locked at the bottom and top of the top closing plate 7, and the third nut 82 is locked at the bottom of the top block 1. When the lifting member adjusts the height of the top block, the height of the top block 1 is changed by adjusting the locking position of the nut 82, thereby adjusting the height of the top block 1 to accommodate the support of spindles 200 of different sizes.

[0038] The specific implementation principle of the utility model is: before the impeller 100 is transported over long distances, the transverse bracket 3 is first fixed to the fixed surface 300 via the fastener 4, and then the height of the top block 1 is adjusted by the lifting member 8 so that the top block 1 is just supported on the bottom of the main shaft 200, preventing the impeller 100 from rotating during transportation, solving the problem that the bearing of the impeller 100 is easily damaged during transportation, and facilitating transportation.

[0039] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
