Description

Technical Field

[0001] This utility model relates to the field of hydropower generation technology, specifically to a hoisting and transporting device. Background Technology

[0002] During the overhaul of large hydro-generator units, the generator and turbine are dismantled simultaneously. The dismantled turbine components need to be moved out of the turbine pit, with most requiring transport from the turbine room corridor to the outside. However, most of these components are irregularly shaped and weigh over 300 kg. Current techniques involve welding lifting points into the turbine pit lining and using hand-operated hoists to move them between sections into the corridor. Then, manual forklifts are used to transport the dismantled components outside the turbine room. However, using numerous hand-operated hoists poses risks of hoist damage and lifting point detachment. During forklift transport, limited aisle space and ground protection necessitate repeated adjustments to forklift positions and manual intervention to move components, requiring multiple people and increasing the risk of injury from tipping over heavy objects. Reinstalling these components using the same procedure to move them back to the turbine pit is inefficient and poses significant safety hazards. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is a reference to the appendix. Figures 1 to 5 The hoisting and transfer equipment 100 of this utility model embodiment is described in detail.

[0030] The hoisting and transferring device 100 of this embodiment includes a support 1, hoisting components 2, hoisting beams 3, and an electric hoist 4. Multiple hoisting components 2 are arranged at intervals along a first direction (e.g., the left-right direction in the figure) on the support 1, with installation gaps between them. The hoisting beam 3 has a first end 34 and a second end 35 opposite each other in a second direction (e.g., the up-down direction in the figure). The first end 34 of the hoisting beam 3 is movably disposed within the multiple installation gaps along the first direction, which is perpendicular to the first direction. The electric hoist 4 is movably disposed at the second end 35 along the first direction.

[0031] When using the hoisting and transfer equipment 100 of this utility model embodiment, the hoisting and transfer equipment 100 is first assembled at the hoisting position. For example, in the maintenance process of a hydro-generator set, such as... Figures 1 to 2 As shown, the hoisting location is the water turbine room corridor 200, and the support frame 1 is installed within the corridor 200. The first direction is the same as the left-right direction, and the second direction is the same as the up-down direction. When it is necessary to hoist a workpiece located in the machine pit 300, as... Figure 1 As shown, move the electric hoist 4 to the right side of the lifting beam 3, push the lifting beam 3 to the right (that is, move it towards the pit 300), so that the electric hoist 4 is above the workpiece 400. Then operate the electric hoist 4 to lift the workpiece 400, and then pull the lifting beam 3 to the left, as shown. Figure 2 As shown, operate the electric hoist 4 to move to the left, moving the workpiece 400 from the pit 300 to the transfer cart 500 on the left side of the corridor 200. Then, operate the electric hoist 4 to place the workpiece 400 onto the transfer cart 500, thus completing the operation of hoisting the workpiece 400 from inside the pit 300 to the outside. When it is necessary to hoist the workpiece 400 back into the pit 300, simply reverse the above steps to hoist the workpiece 400 from the transfer cart 500 into the pit 300.

[0032] The hoisting and transfer equipment 100 of this utility model embodiment, combined with the structure of the water turbine room corridor 200, uses a sliding hoisting beam 3 and an electric hoist 4 to hoist and lift the workpiece located in the machine pit 300, and then move the workpiece to the transfer position (the position of the transfer vehicle 500). It can directly hoist and transport the dismantled parts from the water turbine room to the outside of the water turbine room without the need for multiple hand hoists and forklifts, which not only improves the safety and reliability of the operation process, but also improves the work efficiency.

[0033] In some embodiments, such as Figures 1 to 3As shown, the support frame 1 includes multiple support beams 11 and multiple support columns 12. The multiple support beams 11 are arranged at intervals along the first direction, and the support beams 11 are in a third direction (e.g., Figure 4 Support columns 12 are provided on both sides of the support beam 11 in the front-back direction. A hoisting assembly 2 is provided in the middle of the support beam 11 in the third direction, which is orthogonal to the first and second directions. The support columns 12 extend in the vertical direction, and multiple support beams 11 and multiple support columns 12 form a portal frame, which provides support for the hoisting and transfer equipment 100 of this utility model embodiment.

[0034] In some embodiments, the support frame 1 further includes a reinforcing rib 13, which connects two adjacent support columns 12 in the first direction. The reinforcing rib 13 extends along the first direction, increasing the limiting position of the support columns 12 in the first direction and preventing the support columns 12 from tilting in the first direction, thereby further ensuring the stability of the support frame 1, and consequently ensuring the stability and reliability of the hoisting and transferring equipment 100 of this embodiment.

[0035] In some embodiments, the support 1 further includes a foot 14, which is disposed on the side of the support column 12 away from the support beam 11 in the second direction, and the foot 14 is threadedly connected to the support column 12. As shown in the figure, the foot 14 is located on the lower side of the support column 12, and the foot 14 is threadedly connected to the support column 12. The foot 14 can rotate relative to the support column 12, thereby adjusting the vertical position of the foot 14 to ensure that the support column 12 can adapt well to the floor of the corridor 200, ensuring the stability of the support column 12, and at the same time adjusting the overall height of the support 1 to improve the adaptability of the support 1 to different heights.

[0036] Specifically, the support beam 11 is arc-shaped, and the arc of the support beam 11 is the same as or similar to the arc of the water turbine room corridor 200. The upper side of the support beam 11 is adjacent to the upper wall of the water turbine room corridor 200, and the support column 12 is adjacent to the side wall of the water turbine room corridor 200.

[0037] In some embodiments, such as Figure 4As shown, the support 1 further includes a wall guard 15, which is disposed on the support column 12 to abut against the wall of the water turbine room corridor 200. The wall guard 15 can protect the wall of the corridor 200, preventing the support 1 from vibrating or tilting and causing damage to the wall of the corridor 200 when the hoisting and transfer equipment 100 of this utility model hoists the workpiece. At the same time, the wall guard 15 increases the interaction area and force between the support column 12 and the wall of the corridor 200, so that the wall of the corridor 200 can limit the support column 12, preventing the support column 12 from vibrating and tilting during operation, improving the stability of the support 1, and further improving the stability and reliability of the hoisting and transfer equipment 100 of this utility model.

[0038] like Figure 4 As shown, the support frame 1 further includes a leveling pad 16, which is disposed on the side (upper side) of the support beam 11 away from the support column 12 in the second direction to abut against the wall of the water turbine room corridor 200. The lower side of the leveling pad 16 abuts against the support beam 11, and the upper side of the leveling pad 16 abuts against the top wall of the water turbine room corridor 200, increasing the interaction area and force between the support beam 11 and the corridor 200, further improving the stability of the support frame 1, and thus further improving the stability and reliability of the hoisting and transfer equipment 100 of this utility model embodiment.

[0039] In some embodiments, such as Figure 4 and Figure 5 As shown, the hoisting assembly 2 includes a mounting frame 21, a first gear 22, and a first rack 23. The mounting frame 21 is mounted on the bracket 1. The first gear 22 is rotatably mounted on the mounting frame 21. The gap between the first gear 22 and the mounting frame 21 in the second direction forms an installation gap. The first rack 23 is located on one side (lower side) of the first end 34 in the second direction, and the first rack 23 meshes with the first gear 22. The first end 34 of the hoisting beam 3 is located within the installation gap between the first gear 22 and the mounting frame 21. The first gear 22 provides support and limits the lower side of the first end 34 of the hoisting beam 3. The meshing of the first gear 22 and the first rack 23 ensures that the hoisting beam 3 can move relative to the first gear 22 when it is pushed, avoiding the problem of slippage of the hoisting beam 3, which would result in slow movement efficiency and difficulty in controlling the movement distance.

[0040] Specifically, the mounting bracket 21 is located in the middle of the support beam 11.

[0041] In some embodiments, the lifting assembly 2 further includes a guide wheel 24, which is rotatably mounted on the mounting frame 21 and abuts against the other side (upper side) of the first end 34 in the second direction. The guide wheel 24 is in a rolling connection with the upper side of the first end 34, and the guide wheel 24 can limit the upper side of the first end 34 to prevent the lifting beam 3 from tilting up and down, ensuring the stability of the lifting beam 3, thereby further ensuring the stability and reliability of the lifting and transfer equipment 100 in this embodiment of the present invention during use.

[0042] In some embodiments, the lifting beam 3 is an I-beam, and the mounting frame 21 includes a mounting plate 211, a first mounting arm 212 and a second mounting arm 213. The mounting plate 211 is connected to the bracket 1. The first mounting arm 212 and the second mounting arm 213 are opposite each other in the third direction. One end of the first mounting arm 212 and one end of the second mounting arm 213 in the second direction are both connected to the mounting frame 21. The inner side of the first mounting arm 212 and the inner side of the second mounting arm 213 are both provided with a first gear 22.

[0043] Mounting plate 211 is located in the middle of support beam 11. Mounting frame 21, first mounting arm 212 and second mounting arm 213 form an n-shaped mounting frame 21, which facilitates the installation of two opposing first gears 22. This facilitates the two first gears 22 to support and cooperate with both sides of the first end 34 of the I-beam, thereby improving the stability and reliability of the mounting frame 21 in supporting the first end of the I-beam.

[0044] In some embodiments, the lifting beam 3 includes a beam body 31 and baffles 32. The beam body 31 is disposed within the installation gap, and baffles 32 are provided at both ends of the beam body 31 in the first direction. The baffles 32 connect the first end 34 and the second end 35. The beam body 31 is the main part of the I-beam. The two baffles 32 form a limit at the left and right ends of the beam body 31 to prevent the first gear 22 from disengaging from the beam body 31, thereby further ensuring the stability and reliability of the lifting and transferring equipment 100 in this embodiment of the present invention during use.

[0045] In some embodiments, the lifting beam 3 further includes a pull ring 33, which is disposed on the baffle 32. The pull ring 33 protrudes from the baffle 32 and facilitates the binding of ropes, thereby enabling personnel to pull the lifting beam 3 by pulling the ropes to realize the operation and movement of the workpiece.
