Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a safe transport device for the rotor of a large pumping station unit. Background Technology

[0002] As pump station unit rotors operate for longer periods, they will gradually develop various problems. Some of these problems can be resolved on-site, while others require return to the factory for repair. However, due to the large size and weight of the pump station unit rotors, transportation presents significant challenges. During transport, factors such as road bumps, acceleration, and deceleration can cause impacts on the rotors. Therefore, ensuring the safe transportation of pump station unit rotors is a pressing issue that needs to be addressed. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a safe transport device for the rotor of a large pumping station unit. It is not only simple in structure, but also can better secure the rotor, reduce the impact force on the rotor, and realize its safe transport.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A safe transport device for the rotor of a large pumping station unit includes a support frame and a positioning clamp;

[0006] The support frame includes a base frame, with an M-shaped bracket connected to each of the top two sides of the base frame. Each M-shaped bracket has a V-shaped support opening at the top center to support the connecting shaft of the rotor. A gap is left between the two M-shaped brackets to accommodate the rotor. A reinforcing brace is connected to the outer side of the M-shaped bracket.

[0007] The positioning fixture includes a clamping plate, the middle of which forms an arc-shaped clamping opening that mates with the upper part of the connecting shaft. The two ends of the clamping plate extend to form first connecting portions. The tops of the M-shaped brackets on both sides of the V-shaped support opening respectively form second connecting portions. The first and second connecting portions are connected by bolts to secure the connecting shaft in the V-shaped support opening. A positioning block is connected to the top of the clamping plate. The positioning block is provided with an adjusting screw hole. A positioning screw is connected inside the adjusting screw hole. A handwheel is connected to the outer end of the positioning screw, and an abutment rubber sleeve is connected to the inner end.

[0008] Preferably, a first buffer pad is provided on the inclined surface of the V-shaped support opening, and a second buffer pad is provided inside the arc-shaped clamping opening.

[0009] Preferably, a pad is also provided between the first buffer pad and the V-shaped support opening.

[0010] Preferably, the support frame is made of steel.

[0011] The advantages of this utility model using the above-mentioned technical solution are as follows: The large pump station unit rotor safety transport device has a relatively stable support frame structure formed by the base frame, M-shaped bracket, and reinforcing brace, which can stably bear the weight of the rotor and prevent it from rolling or shifting during transportation; the specially made positioning clamp can firmly fix the rotor on the bracket, which can not only limit its vertical movement but also achieve circumferential limit, ensuring that the rotor will not loosen or shake during transportation and guaranteeing transportation safety; the structure of the first buffer pad, the second buffer pad, and the abutment rubber sleeve can offset the impact force generated by road bumps, vehicle acceleration or deceleration, etc. during transportation, avoiding the impact force acting directly on the rotor and reducing the risk of damage to the rotor.

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-3As shown, in this embodiment, the rotor safety transport device for the large pump station unit includes a support frame 1 and a positioning clamp 2. The support frame 1 includes a base frame 11, with an M-shaped bracket 12 connected to each of the top two sides of the base frame 11. Each M-shaped bracket 12 has a V-shaped support opening 121 formed at the top center to support the connecting shaft 4 of the rotor 3. A gap is left between the two M-shaped brackets 12 to accommodate the rotor. A reinforcing brace 13 is connected to the outer side of the M-shaped bracket 12. The positioning clamp 2 includes a clamping plate 21, with an arc formed in the middle of the clamping plate 21 that mates with the upper part of the connecting shaft. The clamping plate 21 has two ends that extend to form a first connecting part 22. The top of the M-shaped brackets 12 on both sides of the V-shaped bracket 121 has a second connecting part 122. The first connecting part 22 and the second connecting part 122 are connected by bolts 23 to fasten the connecting shaft 4 in the V-shaped bracket 121. The top of the clamping plate 21 is connected to a positioning block 24. The positioning block 24 is provided with an adjusting screw hole. The adjusting screw hole is connected to a positioning screw 25. The outer end of the positioning screw 25 is connected to a handwheel 26 and the inner end is connected to an abutment rubber sleeve 27.

[0018] In use, first transfer the connecting shaft with the rotor to the V-shaped bracket of the M-type bracket by means of hoisting or other means. Then, use the positioning clamp to fasten the connecting shaft in the V-shaped bracket. Finally, adjust the positioning screw to press against the rotor to prevent it from shifting in the axial direction. This completes the fixing process. The above fixing is relatively stable and can ensure the safe transportation of the rotor.

[0019] In one embodiment, a first buffer pad 14 is provided on the inclined surface of the V-shaped support opening 121, and a second buffer pad 28 is provided inside the arc-shaped clamp. The structure of the first buffer pad 14, the second buffer pad 28, and the abutment rubber sleeve can offset the impact force generated during transportation due to road bumps, vehicle acceleration or deceleration, etc., to avoid the impact force acting directly on the rotor and reduce the risk of damage to the rotor.

[0020] In one embodiment, depending on the different diameters of the connecting shafts or the different front and rear diameters of the same connecting shaft, the height can be increased by setting a pad 15. Specifically, a pad can be set between the first buffer pad 14 and the V-shaped support 121 to ensure that the center lines of the two V-shaped support coincide.

[0021] In one embodiment, the support frame 1 is made of steel bracket, which can be connected and fixed by channel steel.

[0022] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0023] Any aspects of this utility model not described in detail are known to those skilled in the art.
