Description

Technical Field

[0001] This utility model belongs to the field of large-scale infrastructure transportation, specifically relating to a bucket turbine blade transportation mechanism for narrow passages. Background Technology

[0002] like Figure 1 As shown, large bucket turbine discs are a common component of large hydraulic facilities. Since their production and use are often in different locations, it is unavoidable to transport them using pre-arranged large trailers (SPTs).

[0003] When transporting bucket turbine discs by large trailers, the bucket turbine discs need to be placed horizontally on the load-bearing horizontal surface of the large trailer with the end face as the placement surface. In order to ensure the stability of the large bucket turbine discs, which weigh tens of tons, the center of gravity of the large bucket turbine discs should be strictly aligned with the load-bearing horizontal surface before being transported by large trailers.

[0004] However, the diameter of the placement surface formed by the end face of the large bucket turbine is significantly larger than the width of the bearing horizontal plane. In order to keep the center of gravity of the large bucket turbine from deviating from the bearing horizontal plane, the opposite two sides of the large bucket turbine placed on the bearing horizontal plane extend beyond the two sides of the width direction of the large trailer. However, this makes it impossible for the large trailer carrying the large bucket turbine to pass through narrow roads (roads with one side of a mountain and the other side of a cliff). Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bucket turbine blade transport mechanism for narrow passages. By mounting a large bucket turbine disc on a large trailer, the large trailer carrying the large turbine disc can pass through narrow passages.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A bucket turbine blade transport mechanism for narrow passages, mounted on a predetermined trailer, wherein a connecting flange surface is formed in the middle of the bucket turbine blade, and a through hole for the shaft is located at the center of the connecting flange surface, characterized in that it comprises: a base, detachably mounted on the predetermined trailer via its bottom, a tilting hinge support at the top of the base, the rotation axis of the tilting hinge support serving as the tilting axis, the tilting axis extending horizontally, a connecting fixture having a connecting flange corresponding to the connecting flange surface, and the connecting fixture hinged to the tilting hinge support, and a pair of tilting components symmetrically distributed about the tilting axis, the tilting components including a tilting cylinder, a pair of oil supply lines, and a reversing valve, the tilting cylinder being hollow and mounted on the base, having a first cylinder inlet, a second cylinder inlet, and a piston rod through hole, a tilting piston being movably mounted inside the tilting cylinder, the angle between the extension direction of the tilting piston and the vertical direction being at a predetermined angle. Within the included angle range, the tilting piston has an integrally formed first piston rod and a first piston head. The circumference of the first piston head is sealed against the inner wall of the tilting cylinder, and the circumference of the first piston rod is sealed against the inner wall of the piston rod through hole. The free ends of both piston rods are hinged to the bottom surface of the connecting flange, and the line connecting the two hinge points passes through the center of the connecting flange. The first cylinder inlet of one tilting cylinder and the second cylinder inlet of the other tilting cylinder are both connected to an oil supply line, and the second cylinder inlet of one tilting cylinder and the first cylinder inlet of the other tilting cylinder are both connected to another oil supply line. When the external oil supply device supplies oil through one oil supply line via a reversing valve, the two tilting pistons perform reversible and synchronous piston movements, thereby causing the bucket turbine disc to tilt in the vertical plane around a horizontal axis passing through its own diameter.

[0007] Preferably, the tilting assembly further includes a one-way hydraulic lock connected to the tilting cylinder. The one-way hydraulic lock is hollow, and its inner wall has a first flange, a second flange, and a third flange distributed sequentially along a predetermined direction. The first flange, the second flange, and the third flange divide the interior of the one-way hydraulic lock into a first cavity, a second cavity, a third cavity, and a fourth cavity, respectively. A one-way piston is movably disposed in the second cavity. The one-way piston has an integrally continuous second piston rod and a second piston head. The circumferential direction of the second piston head is sealed and fitted against the inner wall of the second cavity, and the second piston head is larger than the second piston rod. The first cavity is close to the first flange, the third flange forms a one-way cut-off through hole, the cross-sectional area of ​​the second piston rod is smaller than the through area of ​​the one-way cut-off through hole, the fourth cavity is provided with a cut-off entity, and the cut-off entity is elastically and repositionably disposed in the fourth cavity by elastically abutting against the inner wall of the fourth cavity, and the cut-off entity normally closes the one-way cut-off through hole, the first cavity has a first inlet connected to an oil supply line and a first outlet connected to the inlet of the first oil cylinder, the third cavity has a second inlet connected to another oil supply line, and the fourth cavity has a second outlet connected to the inlet of the second oil cylinder. Preferably, the top of the base is also formed with two symmetrical pin joint grooves, and the bottom surface of the connecting flange is also formed with a pair of rotating arc plate portions corresponding to the pin joint grooves. The pair of rotating arc plate portions are parallel, and the line connecting the centers of the pair of rotating arc plate portions is in the same vertical plane and parallel to each other with the flipping axis. Thus, when the two flipping pistons perform reversible and synchronous piston movements, the rotating arc plate portions rotate relative to the pin joint grooves, thereby causing the bucket turbine disc to flip.

[0008] Furthermore, the side of the pin-connecting lug has a pin-connecting through hole, and the edge of the rotating arc plate has several anti-rotation through holes formed along its own circumference. Thus, the rotating arc plate rotates so that the pin-connecting through hole corresponds to the anti-rotation through hole, and the rotation positioning of the connecting tool and the bucket turbine disc is achieved by pinning the anti-rotation through hole to the pin-connecting through hole.

[0009] Furthermore, the central angle of the envelope of several anti-rotation through holes on the rotating arc plate is 100°, thereby enabling the bucket turbine disc to rotate ±50° with the vertical plane as the reference. Furthermore, this utility model also includes an anti-rotation component, comprising an anti-rotation cylinder and an anti-rotation pin. The outer surface of the pin connection hole has a cylinder bracket, the anti-rotation cylinder is mounted on the cylinder bracket, and the anti-rotation pin is detachably mounted on the output shaft of the anti-rotation cylinder. The anti-rotation pin is inserted into the pin connection hole, so that when the output shaft of the anti-rotation cylinder extends under the drive of an external drive signal, the anti-rotation pin connects the anti-rotation hole and the pin connection hole; when the output shaft of the anti-rotation cylinder retracts under the drive of an external drive signal, the pin connection between the anti-rotation hole and the pin connection hole is released.

[0010] Furthermore, the opposing sides of the two pin-connecting lugs together form a flip hinge support.

[0011] Preferably, the base has a frustum structure that is smaller at the top and larger at the bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Because the bucket turbine blade transport mechanism for narrow channels of this utility model includes a base, a connecting fixture, and a pair of tilting components, the base is detachably mounted on a predetermined trailer via its bottom, and the top of the base has a tilting hinge support with a tilting axis. The connecting fixture has a connecting flange for connecting the turbine disc, and the connecting fixture is hinged to the tilting hinge support. The pair of tilting components are symmetrically distributed about the tilting axis. Each tilting component includes a tilting cylinder, a pair of oil supply lines, and a reversing valve. The tilting cylinder has a first cylinder inlet, a second cylinder inlet, and a piston rod through-hole. A tilting piston is movably mounted inside the tilting cylinder, and the angle between the extension direction of the tilting piston and the vertical direction is within a predetermined angle range. The free ends of both piston rods are hinged to the bottom surface of the connecting flange, and the line connecting the two hinge points passes through the connecting flange. At the center, the first cylinder inlet of one tilting cylinder and the second cylinder inlet of another tilting cylinder are both connected to an oil supply line, and the second cylinder inlet of one tilting cylinder and the first cylinder inlet of another tilting cylinder are both connected to another oil supply line. When the external oil supply device supplies oil through one oil supply line via a reversing valve, the two tilting pistons perform reversible and synchronous piston movements, thereby causing the bucket turbine disc to tilt in the vertical plane around a horizontal axis passing through its own diameter. That is, while ensuring that the center of gravity of the large bucket turbine disc does not deviate from the correspondence with the bearing horizontal plane, the extension width of the large bucket turbine disc along the width direction of the large trailer is significantly reduced. Therefore, this utility model, when used to mount the large bucket turbine disc on a large trailer, enables the large trailer carrying the large turbine disc to pass through narrow passages.

[0013] 2. Because the tilting assembly of this utility model also includes a one-way hydraulic lock connected to the tilting cylinder, the inner wall of the one-way hydraulic lock is formed with a first cavity, a second cavity, a third cavity and a fourth cavity distributed sequentially along a predetermined direction. A one-way piston is movably arranged in the second cavity. The circumferential direction of the second piston head of the one-way piston is sealed and fitted with the inner wall of the second cavity, and the second piston head is closer to the first flange than the second piston rod. The third flange forms a one-way cut-off through hole. The cross-sectional area of ​​the second piston rod is smaller than the through area of ​​the one-way cut-off through hole. A cut-off entity is provided in the fourth cavity, and the cut-off entity is elastically and repositionably arranged in the fourth cavity by elastically abutting against the inner wall of the fourth cavity. The cut-off entity keeps the one-way cut-off through hole normally closed. Therefore, this utility model locks the oil in the tilting cylinder to prevent backflow through the one-way hydraulic lock, ensuring the stability of the tilting piston movement, thereby ensuring the dynamic support of a large water turbine weighing tens of tons.

[0014] 3. Because the side of the pin-connecting ear groove of this utility model has a pin-connecting through hole, and the edge of the rotating arc plate has a number of anti-rotation through holes along its own circumference, the rotating arc plate can rotate to make the pin-connecting through hole correspond to the anti-rotation through hole. Then, by pinning the anti-rotation through hole and the pin-connecting through hole, the rotational positioning of the connecting tool and the bucket turbine disc is achieved. Therefore, this utility model achieves stable positioning of the bucket turbine disc at several rotation angles by pinning the anti-rotation through hole and the pin-connecting through hole.

[0015] 4. Because this utility model also includes an anti-rotation component, including an anti-rotation cylinder and an anti-rotation pin, the outer surface of the pin connection hole has a cylinder bracket, the anti-rotation cylinder is mounted on the cylinder bracket, and the anti-rotation pin is detachably mounted on the output shaft of the anti-rotation cylinder, and the anti-rotation pin is inserted into the pin connection hole. Thus, when the output shaft of the anti-rotation cylinder extends under the drive of an external drive signal, the anti-rotation pin connects the anti-rotation hole and the pin connection hole; when the output shaft of the anti-rotation cylinder retracts under the drive of an external drive signal, the pin connection between the anti-rotation hole and the pin connection hole is released. Therefore, this utility model can achieve stable positioning of the bucket turbine disc at several rotation angles through an external drive signal.

[0016] 5. Because the opposing sides of the two pin-connecting lugs of this utility model together form a flip hinge support, the structure of this utility model is relatively compact.

[0017] 6. Because the base of this utility model has a frustum structure that is smaller at the top and larger at the bottom, this utility model can make the weight of the large water turbine disk occupy a larger effective surface on the large trailer by using a larger base bottom surface, thereby reducing the corresponding pressure value.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the bucket turbine blade transport mechanism for narrow channels of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0021] like Figure 2 As shown, the bucket turbine blade transport mechanism 100 for narrow passages in this embodiment is mounted on a predetermined trailer. A connecting flange surface B1 is formed in the middle of the bucket turbine disk B. The center of the connecting flange surface B1 has a through hole B11. Specifically, the connecting flange surface B1 also has multiple flange thread holes B12.

[0022] The bucket turbine blade transport mechanism 100 for narrow channels includes a base 10, a connecting fixture 20, a tilting assembly, and an anti-rotation assembly 40.

[0023] The base 10 has a frustum structure that is smaller at the top and larger at the bottom, and is horizontally mounted on the intended trailer by means of a detachable bottom.

[0024] The top of the base 10 has a flip hinge support 11a, with the rotation axis of the flip hinge support 11a serving as the flip axis D. The flip axis D extends horizontally. Specifically, the bucket turbine disk B is hinged on the flip hinge support 11a via the connecting fixture 20, so that the bucket turbine disk B can flip relative to the base 10 in the vertical plane with the flip axis D as the rotation axis.

[0025] The top of the base 10 has two symmetrical pin-connecting lugs 11. The side of the pin-connecting lug 11 has a pin-connecting through hole 11b. The opposing sides of the two pin-connecting lugs 11 together form a flip hinge support 11a. Specifically, each pin-connecting lug 11 has two sides, that is, each pin-connecting lug has a pair of pin-connecting through holes 11b. Thus, the flip hinge support 11a also has a pair of pin-connecting through holes 11b. The centers of all the pin-connecting through holes 11b are located on the same horizontal line, and the horizontal line is parallel to each other in the same vertical plane as the flip axis D. like Figure 3 As shown, the connecting fixture 20 is hinged on the flip hinge support 11a, and the connecting fixture 20 has a connecting flange 21 and a rotating arc plate portion 22.

[0026] The connecting flange 21 is threaded to the mating flange face B1. There is a pair of rotating arc plate portions 22 that are parallel to each other and are formed on the bottom surface of the connecting flange 21. The pair of rotating arc plate portions 22 are inserted into the pin lug groove 11. The line connecting the centers of the pair of rotating arc plate portions 22 and the rotation axis D are in the same vertical plane and are parallel to each other. Specifically, the connecting flange 21 is a horizontal circular plate and has multiple mating thread holes 21a corresponding to the flange thread hole B12. The rotating arc plate portion 22 is perpendicular to the connecting flange 21 and has an arc-shaped profile.

[0027] Specifically, when the connecting fixture 20, which is threadedly connected to the bucket turbine disc B, rotates relative to the base 10 around the flip axis D, the rotating arc plate 22 rotates relative to the base 10 within the pin groove 11.

[0028] The edge of the rotating arc plate 22 has several anti-rotation through holes 22a along its circumference. Thus, by rotating, the rotating arc plate 22 causes one of the pin-connecting through holes 11b to correspond with the anti-rotation through hole 22a. Then, by pinning the anti-rotation through hole 22a with the pin-connecting through hole 11b, the rotating arc plate 22 cannot rotate relative to the base 10, thereby achieving the rotational positioning of the connecting tool 20 and the bucket turbine disk B relative to the base 10.

[0029] The central angle of the envelope of the several anti-rotation through holes 22a in the rotating arc plate portion 22 is 100°, thereby enabling the bucket turbine disk B to rotate by ±50° with the vertical plane as the reference, and the bucket turbine disk B is in a horizontal state before it is rotated.

[0030] In this embodiment, the bottom surface of the connecting flange 21 is also formed with a hinge plate portion 23 and a hinge ear portion 24. The connecting fixture 20 is hinged on the flip hinge support 11a through the hinge plate portion 23, and the hinge ear portion 24 is used to hinge with the flip assembly.

[0031] The number of the overturning components is one pair, symmetrically distributed about the overturning axis D. The overturning components include an overturning cylinder 31, a one-way hydraulic lock 32 connected to the overturning cylinder 31, a pair of oil supply lines P, and a reversing valve (not shown in the figure).

[0032] like Figure 4 As shown, the tilting cylinder 31 is hollow and mounted on the base 10, and has a first cylinder inlet 31a, a second cylinder inlet 31b, and a piston rod through hole (not shown in the figure). A tilting piston 311 is movably disposed inside the tilting cylinder 31. The angle between the extension direction of the tilting piston 311 and the vertical direction is within a predetermined angle range. The tilting piston 311 has an integrally formed first piston rod portion 311b and a first piston head 311a. The circumferential direction of the first piston head 311a is sealed and fitted against the inner wall of the tilting cylinder 31, and the circumferential direction of the first piston rod portion 311b is aligned with the hole of the piston rod through hole. The inner wall of the channel is sealed and fitted, and the free ends of the two piston rod portions 311b are hinged to the bottom surface of the connecting flange 21. The line connecting the two hinge points passes through the center of the connecting flange 21. Specifically, the first piston head 311a and the first piston rod portion 311b form a dynamic sealing structure with the inner wall of the tilting cylinder 31 and the inner wall of the channel of the piston rod through hole, respectively, through piston movement. The predetermined included angle range is small, so the extension line of the tilting piston 311 is basically vertical. In this embodiment, the free end of the piston rod portion 311b is hinged to the connecting flange 21 through the hinge ear portion 24.

[0033] like Figure 5 As shown, the first cylinder inlet 31a of one tilting cylinder 31 and the second cylinder inlet 31b of the other tilting cylinder 31 are both connected to an oil supply line P. The second cylinder inlet 31b of one tilting cylinder 31 and the first cylinder inlet 31a of the other tilting cylinder 31 are both connected to another oil supply line P. When an external oil supply device (not shown in the attached figure) supplies oil through one of the oil supply lines P via a reversing valve, the two tilting pistons 31 perform reversible and synchronous piston movements, thereby causing the bucket turbine disk B to tilt in the vertical plane with a horizontal axis passing through its own diameter as the axis of rotation. That is, when the two tilting pistons 311 perform reversible and synchronous piston movements, they rotate relative to the pin joint groove 11 with the rotating arc plate part 22, thereby causing the bucket turbine disk B to tilt.

[0034] like Figure 6As shown, the one-way hydraulic lock 32 is hollow, and its inner wall has a first flange 321, a second flange 322, and a third flange 323 arranged sequentially along a predetermined direction. These flanges divide the interior of the one-way hydraulic lock 32 into a first cavity 321a, a second cavity 321b, a third cavity 322a, and a fourth cavity 323a. A one-way piston 324 is movably disposed within the second cavity 321b. The one-way piston 324 has an integrally continuous second piston rod portion 324b and a second piston head 324a. The circumferential direction of the second piston head 324a is sealed and fitted against the inner wall of the second cavity 321b. The second piston head 324a is closer to the first flange 321 than the second piston rod 324b. The third flange 323 forms a one-way shut-off through hole 323b that connects the third cavity 322a and the fourth cavity 323a. The cross-sectional area of ​​the second piston rod 324b is smaller than the through area of ​​the one-way shut-off through hole 323b. Specifically, the one-way hydraulic lock 32 is cuboid, and its predetermined direction is its length direction. When the one-way piston 324 moves, the second piston head 324a and the inner wall of the second cavity 321b form a dynamic sealing structure. At this time, the second piston rod 324b can pass through the one-way shut-off through hole 323b and enter the fourth cavity 323a.

[0035] A stop body 325 is provided in the fourth cavity 323a. The stop body 325 is elastically and repositionably disposed in the fourth cavity 323a by elastically abutting against the inner wall of the fourth cavity 323a. The stop body 325 normally closes the one-way stop hole 323b. Specifically, when the second piston rod 324b can pass through the one-way stop hole 323b and enter the fourth cavity 323a, the second piston rod 324b can push open the stop body 325, so that the third cavity 322a communicates with the fourth cavity 323a through the one-way stop hole 323b. In this embodiment, the stop body 325 is spherical.

[0036] The first chamber 321a has a first inlet 32a connected to an oil supply line and a first outlet 32c connected to the first cylinder inlet 31a. The third chamber 322a has a second inlet 32b connected to another oil supply line. The fourth chamber 323a has a second outlet 32d connected to the second cylinder inlet 31b. Specifically, the one-way hydraulic lock 32 is a mature product used in the field and can be conveniently purchased on the market. In this embodiment, the one-way hydraulic lock 32 is disposed on the circumferential surface of the tilting cylinder 31.

[0037] The anti-rotation assembly 40 includes an anti-rotation cylinder (not shown in the figure) and an anti-rotation pin (not shown in the figure).

[0038] The outer surface of the entity containing the pin connection hole 11b also has a cylinder bracket 12. The anti-rotation cylinder is mounted on the cylinder bracket 12. The anti-rotation pin is detachably mounted on the output shaft of the anti-rotation cylinder, and the anti-rotation pin is inserted into the pin connection hole 11a. Thus, when the output shaft of the anti-rotation cylinder extends under the drive of an external drive signal, the anti-rotation pin connects the anti-rotation hole 22a and the pin connection hole 11b. When the output shaft of the anti-rotation cylinder retracts under the drive of an external drive signal, the pin connection between the anti-rotation hole 22a and the pin connection hole 11b is released. Specifically, the anti-rotation pin connects the anti-rotation hole 22a and the pin connection hole 11b, and only passes through the pin connection hole 11b outside the pin connection lug 11.

[0039] The following describes the implementation of the bucket turbine blade transport mechanism 100 for narrow channels with reference to the embodiments: When the planned trailer (not shown in the attached drawings) is positioned on the narrow passage, the bucket turbine disk B is rotated relative to the base 10 in advance, so that the orthographic projection of the bucket turbine disk B on the horizontal plane narrows. The anti-rotation pin 42 is driven by a signal to position the connecting tool 20 on the base 10, so that the bucket turbine disk B is fixed relative to the base 10. Then, the planned trailer carrying the inclined bucket turbine disk B passes through the narrow passage.

[0040] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
