Abstract
Description
Technical Field
[0001] The invention relates to the technical field of hoisting devices, and in particular to a hydraulic brake maintenance hoisting device. Background Art
[0002] The braking system of a hydro-turbine generator set usually includes brakes, brake control systems, sensors and other components. The brake of a hydro-turbine generator set is mainly used for the unit shutdown braking and the force conversion rotor jacking of the hydro-turbine generator set. When the speed is lower than 10% during the unit shutdown process, the brake chamber is inflated, the brake is lifted, and the brake gate is in contact with the brake ring. At this time, the brake provides a braking torque for the unit to prevent the unit from running at a low speed for a long time, causing bearing wear or burning. After the unit is shut down, the brake chamber is exhausted, the return chamber is inlet, and the brake gate falls. The turbine rotor brake plays an important role in the operation of the turbine and can ensure the safe and reliable shutdown of the unit.
[0003] The weight of a single brake can generally reach 500kg. When the brake is not under pressure, the gap between the brake and the gate is about 10mm. After the unit was put into operation for a period of time, there was a gas blowby defect between the brake chamber and the return chamber, and the brake could not work normally. After the construction personnel removed the brake fixing bolts, they used steel pipes, slings and other tools to remove the brake and directly rely on manual maintenance of the brake, which required a large number of personnel and high work intensity.

DETAILED DESCRIPTION
[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.
[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0035] Example 1 Reference Figures 1 to 6 , a hydraulic brake maintenance hoisting device is provided, including a lifting frame 100, which includes a first frame 101 and a second frame 102 that can be connected to the first frame 101; the purpose of setting the first frame 101 and the second frame 102 is to provide a device for stably moving the rotor brake 900. After the first frame 101 and the second frame 102 are connected, they can form a hoisting device with a horizontal track and a vertical track. Compared with directly lifting the rotor brake 900, the hoisting device can ensure the stability of the rotor brake 900 when it is lifted, and avoid the problem of the rotor brake 900 shaking and hitting the turbine building structure 800. At the same time, the first frame 101 and the second frame 102 can be disassembled and connected. Before assembly, the first frame 101 and the second frame 102 can be located on both sides of the turbine building structure 800, and after assembly, the hoisting device can span the turbine building structure 800.
[0036] The hydraulic brake maintenance hoisting device includes a lifting mechanism 200 , which is arranged on the first frame 101 . The lifting mechanism 200 is a structure for providing power, which can provide power for lifting and lowering the rotor brake 900 .
[0037] The hydraulic brake maintenance hoisting device includes a swing mechanism 300, which is installed on the first frame 101. The hydraulic brake maintenance hoisting device also includes a moving platform 400, which is arranged on the swing mechanism 300 and can move on the swing mechanism 300, and can reach the second frame 102 through the swing mechanism 300; the moving platform 400 can move on the swing mechanism 300, and as the position of the moving platform 400 on the swing mechanism 300 changes, the swing mechanism 300 can switch between an inclined state and a horizontal state.
[0038] The hydraulic brake maintenance lifting device includes a plug-in mechanism 500, including a pushing member 501 installed on the swing mechanism 300, a force-bearing component 502 slidably installed on the first frame 101, and an insert 503 connected to the force-bearing component 502; when the moving platform 400 moves toward the plug-in mechanism 500 through the swing mechanism 300, the swing mechanism 300 can drive the plug-in mechanism 500 to be inserted into the second frame 102.
[0039] When the swing mechanism 300 swings, it can drive the pusher 501 to swing. When the swing mechanism 300 rotates from the inclined state to the horizontal state, the pusher 501 will rotate counterclockwise. The pusher 501 rotating counterclockwise can push the force-bearing member 502, so that the force-bearing member 502 moves toward the second frame 102, so that the insert 503 is inserted into the inner side of the second frame 102, thereby completing the connection between the first frame 101 and the second frame 102 through the insert 503. When the swing mechanism 300 rotates from the horizontal state to the inclined state, the entire The swing mechanism 300 drives the pushing member 501 to rotate clockwise, and the clockwise rotating pushing member 501 can pull back the force-bearing component 502, so that the force-bearing component 502 drives the inserting member 503 to move away from the second frame 102, so that the inserting member 503 is detached from the inner side of the second frame 102, thereby completing the disconnection between the first frame 101 and the second frame 102. Therefore, by moving the moving platform 400, the state of the swing mechanism 300 is changed, thereby quickly completing the connection or disconnection between the first frame 101 and the second frame 102.
[0040] Specifically, the first frame 101 includes a maintenance platform 101a, and the first frame 101 also includes a vertical frame 101b, which is installed on the maintenance platform 101a, and a lifting mechanism 200 is installed on the vertical frame 101b; a first horizontal frame 101c, which is installed on the vertical frame 101b through the lifting mechanism 200. In this embodiment, the number of first horizontal frames 101c is two, and the positions of the two first horizontal frames 101c can be changed by the lifting mechanism 200. When the rotor brake 900 is removed between the two first horizontal frames 101c, the position of the two first horizontal frames 101c is lowered by the lifting mechanism 200, and the rotor brake 900 can be placed on the maintenance platform 101a for maintenance. In order to facilitate movement, the maintenance platform 101a is equipped with wheels.
[0041] The second frame 102 includes a counterweight seat 102a, and the second frame 102 also includes a lifting leg 102b, which is installed on the counterweight seat 102a; a second cross frame 102c, which is installed on the lifting leg 102b, the first cross frame 101c and the second cross frame 102c can be connected by an insert 503, the counterweight seat 102a has a large mass, and is used to lower the center of gravity of the entire second frame 102 to improve stability, the lifting leg 102b can slide up and down on the counterweight seat 102a, the number and position of the first cross frame 101c and the second cross frame 102c correspond one to one, when the first cross frame 101c moves, it can drive the second cross frame 102c to move up and down, when the first cross frame 101c and the second cross frame 102c are connected, the two can form a transverse track across the turbine building structure 800, which is used to stably support the moving platform 400 and the rotor brake 900.
[0042] Furthermore, the swing mechanism 300 includes a fixed shaft 301, which is installed on the first cross frame 101c; a rocker rod 302, which is rotatably sleeved on the radial surface of the fixed shaft 301; a wheel groove 303, which is opened on the rocker rod 302; and a docking rail 102d is also installed on the second cross frame 102c, and the position of the docking rail 102d corresponds to the position of the rocker rod 302.
[0043] There are two fixed shafts 301, which are respectively installed on the side walls of the two first horizontal frames 101c close to each other. The swing rod 302 can rotate with the fixed shaft 301 as the axis. The two swing rods 302 are provided with wheel grooves 303 to facilitate the movement of the moving platform 400. With the fixed shaft 301 as the center point, the swing rod 302 can be divided into two ends, the end close to the second horizontal frame 102c is the close end 302a, and the end far away from the second horizontal frame 102c is the far end 302b. When the moving platform 400 When the swing arm 302 is located near the end 302a, the swing arm 302 is in a horizontal state as a whole. When the moving platform 400 is located far from the end 302b, the swing arm 302 is in an inclined state as a whole. The reason why the swing arm 302 can maintain a horizontal state when the moving platform 400 is located near the end 302a is that, in addition to the gravity pressure of the moving platform 400, the first horizontal frame 101c is also provided with a supporting protrusion 304. When the swing arm 302 is in a horizontal state, the supporting protrusion 304 supports the swing arm 302 from below.
[0044] Therefore, as the moving platform 400 moves above the swing bar 302 , its gravity can press the swing bar 302 to rotate.
[0045] Furthermore, the pushing member 501 includes an extension arm 501a installed on the rocker arm 302, and a convex shaft 501b arranged on the extension arm 501a; a guide groove 502a is provided on the force-bearing member 502, and the convex shaft 501b extends to the inner side of the guide groove 502a; one end of the insert 503 is connected to the force-bearing member 502 to form a connecting end 503a, and the other end of the insert 503 can be inserted into the inner side of the second cross frame 102c to form a plug-in end 503b; a slot 102e is provided on the second cross frame 102c for the plug-in end 503b to be inserted into.
[0046] A through slide groove 101d is provided on the first horizontal frame 101c, and the through slide groove 101d is generally parallel to the first horizontal frame 101c. The force-bearing component 502 is movably installed on the inner side of the through slide groove 101d. The guide groove 502a has two ends, one end close to the fixed axis 301 is the initial end 502a-1, and the other end is far away from the fixed axis 301 is the end end 502a-2, wherein the initial end 502a-1 is closer to the second frame 102 than the end end 502a-2. When the moving platform 400 is located at the distal end 302b of the swing rod 302, the swing rod 302 is in an inclined state under the action of the gravity of the moving platform 400. At this time, the height of the distal end 302b is lower than the height of the proximal end 302a. The convex shaft 501b is located at the initial end 502a-1 of the through slide groove 101d. When the moving platform 400 moves toward the second horizontal frame 102c, as the moving platform 400 reaches the near end 302a, gravity presses the swing rod 302 to rotate as a whole, and the swing rod 302 rotates counterclockwise. At this time, the swing rod 302 reaches the horizontal state from the inclined state. In this case, the swing rod 302 drives the extension arm 501a to rotate counterclockwise, driving the convex shaft 501b to rotate counterclockwise, and the convex shaft 501b rotates from the initial end 502a-1 to the end end 502a-2. The outer surface of the convex shaft 501b will contact the inner groove wall of the guide groove 502a close to the second frame 102, thereby applying a pulling force to the force-bearing component 502 in the direction of the second frame 102. Therefore, the force-bearing component 502 moves toward the second frame 102, driving the insert 503 to move toward the second frame 102, so that the insert 503 is inserted into the inner side of the slot 102e, completing the quick plug-in of the first horizontal frame 101c and the second horizontal frame 102c.
[0047] Subsequently, the movable platform 400 can continue to move toward the second horizontal frame 102c, reach the docking rail 102d through the horizontal swing rod 302, and reach the corresponding position of the rotor brake 900. When the movable platform 400 reaches the bottom of the rotor brake 900, the first horizontal frame 101c and the second horizontal frame 102c are lifted by the lifting mechanism 200, so that the rotor brake 900 can be separated from the upper surface of the turbine building structure 800. At this time, the movable platform 400 is pushed to move toward the first horizontal frame 101c. The movable platform 400 returns to the top of the swing rod 302 through the docking rail 102d and continues to move toward the distal end 302b of the swing rod 302. When the movable platform 400 reaches the distal end 302b of the swing rod 302, the large mass of the movable platform 400 and the rotor brake 900 will cause the swing rod 302 to quickly convert from a horizontal state to an inclined state.
[0048] Because the gravity of the moving platform 400 and the rotor brake 900 causes the swing rod 302 to tilt, the swing rod 302 rotates clockwise, and the swing rod 302 drives the extension arm 501a to drive the convex shaft 501b to rotate clockwise, so that the convex shaft 501b moves from the end end 502a-2 to the initial end 502a-1. At this time, the outer surface of the convex shaft 501b contacts the inner groove wall of the guide groove 502a away from the second frame 102, thereby applying a thrust away from the second frame 102 to the force-bearing component 502, so that the force-bearing component 502 moves in the direction away from the second horizontal frame 102c, so that the insert 503 is detached from the inner side of the second horizontal frame 102c, thereby completing the disconnection between the first horizontal frame 101c and the second horizontal frame 102c.
[0049] This connection and disconnection method has the following advantages: First, the first horizontal frame 101 c and the second horizontal frame 102 c can be connected and disconnected by moving the moving platform 400 .
[0050] Second, under normal conditions, due to the influence of the downward gravity between the first cross frame 101c and the second cross frame 102c, the structure connecting the first cross frame 101c and the second cross frame 102c will be subjected to a large downward pressure stress in the connected state. If the connection structure between the first cross frame 101c and the second cross frame 102c is removed manually, it will be very laborious. The large mass of the rotor brake 900 can be used to quickly press and disconnect the second cross frame 102c and the first cross frame 101c, which is quick and labor-saving.
[0051] Furthermore, the lifting mechanism 200 includes a gravity body 201 installed on the vertical frame 101 b , a pull rope 202 connected to the gravity body 201 , and a retractable driving member 203 connected to the gravity body 201 via the pull rope 202 .
[0052] In this embodiment, the retractable driving member 203 is composed of a driving motor and a rope shaft. One end of the pull rope 202 is wound around the outside of the rope shaft, and the other end is connected to the gravity body 201. The two first cross frames 101c are both installed on the gravity body 201. By rotating the driving motor forward and reverse, the pull rope 202 can be released or reeled, thereby causing the gravity body 201 to rise or fall.
[0053] Example 2 Reference Figure 3This embodiment is different from the first embodiment in that: the moving platform 400 includes a first arc platform 401, a second arc platform 402 that can be connected to the first arc platform 401, rollers 403 are installed on the first arc platform 401 and the second arc platform 402, and semicircular grooves are opened on the first arc platform 401 and the second arc platform 402, mainly to adapt to the existing rotor brake 900, the first arc platform 401 has at least four rollers 403, so that it can move independently on two swing rods 302 or two docking rails 102d, when the first arc platform 401 reaches the bottom of the rotor brake 900, the first arc platform 401 and the second arc platform 402 are connected, and the positions of the first arc platform 401 and the second arc platform 402 are raised, so that the rotor brake 900 can be separated from the upper surface of the turbine building structure 800.
[0054] The rest of the structure is the same as that of Example 1.
[0055] Example 3 Reference Figures 7 and 8 This embodiment is different from the above embodiments in that: the hydraulic brake maintenance lifting device also includes a one-way locking member 600; it includes a ring seat 601, which is installed on the counterweight seat 102a; a sliding column 602, which is slidably installed on the ring seat 601; a first elastic member 603, which is sleeved on the outer side of the sliding column 602; a locking head 604, which is installed on the sliding column 602; a locking groove 102b-1 is opened on the lifting leg 102b along the axial direction, and the first elastic member 603 can push the locking head 604 to insert into the inner side of the locking groove 102b-1.
[0056] The purpose of setting the one-way locking member 600 is to allow the second cross frame 102c to bear pressure at the same time as the first cross frame 101c, wherein the lifting leg 102b is installed on the counterweight seat 102a, which can move up and down but cannot rotate, and the locking groove 102b-1 is arranged in a straight line, and the downward side of the locking head 604 is the disengagement surface 604a, and the upward side is the positioning surface 604b. When the lifting leg 102b moves upward, the disengagement surface 604a can be used to press the locking head 604, so that the locking head 604 presses the first elastic member 603, so that the lifting leg 102b can move upward stably, but when each lifting leg 102b moves downward, the inner wall of the locking groove 102b-1 presses the positioning surface 604b of the locking head 604, and the locking head 604 cannot retract. Therefore, when under pressure, the lifting leg 102b can help the vertical frame 101b share the pressure, making the entire hydraulic brake maintenance hoisting device more stable.
[0057] The rest of the structure is the same as that of Example 2.
[0058] Example 4 Reference Figures 9 to 11This embodiment is different from the above embodiments in that the hydraulic brake maintenance hoisting device also includes a locking mechanism 700; the purpose of setting the locking mechanism 700 is to ensure that the first cross frame 101c and the second cross frame 102c can maintain a stable connection state during the process of lifting the rotor brake 900, because during the process of lifting the rotor brake 900, the moving platform 400 has been detached from the top of the rocker arm 302 to the top of the docking rail 102d, so the locking mechanism 700 is used to lock the position of the rocker arm 302 at this time.
[0059] The locking mechanism 700 includes a stabilizing seat 701, which is mounted on the convex shaft 501b; an elastic rod 702, which is mounted on the stabilizing seat 701; a resistance member 703, which is mounted on the end of the elastic rod 702 and extends to the inner side of the wheel groove 303; a clamping member 704, which is mounted on the end of the elastic rod 702 away from the resistance member 703; a clamping groove 502b is provided on the force-bearing component 502, and when the rocker arm 302 rotates to a horizontal state, the clamping member 704 is inserted into the inner side of the clamping groove 502b.
[0060] The purpose of setting the elastic rod 702 is to allow the clamping piece 704 to press against the force-bearing component 502. Therefore, when the swing rod 302 is in a tilted state, the clamping piece 704 and the clamping groove 502b are in a misaligned state. Under the elastic force of the elastic rod 702, the clamping piece 704 and the force-bearing component 502 are in contact with each other. When the swing rod 302 changes from the tilted state to the horizontal state, the swing rod 302 rotates counterclockwise, driving the clamping piece 704 to rotate counterclockwise, and the clamping piece 704 moves against the side wall of the force-bearing component 502. When the swing rod 302 reaches the horizontal state, the position of the clamping piece 704 is The position of the clamping groove 502b corresponds to that of the clamping member 704. Under the pulling of the elastic rod 702, the clamping member 704 enters the inner side of the clamping groove 502b. Because the force-bearing component 502 cannot be separated from the through-slot 101d, when the clamping member 704 is located on the inner side of the clamping groove 502b, the entire swing rod 302 cannot rotate, thereby completing the locking of the entire swing rod 302. The swing rod 302 is stably in a horizontal state. Therefore, the inserting member 503 is also in a state of being stably inserted into the second cross frame 102c, thereby improving the connection stability between the first cross frame 101c and the second cross frame 102c.
[0061] Specifically, the elastic rod 702 includes a sliding body 702a slidably mounted on the rocker arm 302, a through column 702b connected to the sliding body 702a and penetrating the stable seat 701, and a second elastic member 702c sleeved on the through column 702b; the second elastic member 702c can push the sliding body 702a away from the stable seat 701.
[0062] The resistance member 703 is installed on the sliding body 702a, and penetrates the swing rod 302 to reach the inner side of the wheel groove 303. The penetrating column 702b can move along the stable seat 701. When no force is applied, the second elastic member 702c pushes the sliding body 702a away from the stable seat 701.
[0063] Furthermore, the clamping member 704 includes a curved member 704a installed on the through column 702b, the installation position of which is located at the end of the through column 702b away from the sliding body 702a, and a positioning column 704b installed on the curved member 704a; the positioning column 704b interferes with the side wall of the force-bearing member 502 having the clamping groove 502b.
[0064] When the movable platform 400 moves toward the second horizontal frame 102c, the swing arm 302 rotates counterclockwise to a horizontal state. During this process, the swing arm 302 drives the convex shaft 501b to rotate counterclockwise through the extension arm 501a, and the convex shaft 501b rotates toward the end end 502a-2. The outer surface of the convex shaft 501b will contact the inner groove wall of the guide groove 502a close to the second frame 102, thereby applying a pulling force to the force-bearing component 502 in the direction of the second frame 102. Therefore, during this process, the force-bearing component 502 can be pushed, so that the force-bearing component 502 pushes the insert 503, so that the insert 503 is inserted into the inner side of the slot 102e, and the quick plug-in of the first horizontal frame 101c and the second horizontal frame 102c is completed.
[0065] At the same time, as the swing rod 302 rotates counterclockwise, the clamping member 704 will be driven to rotate counterclockwise, and the positioning column 704b in the clamping member 704 will contact the side of the force-bearing component 502 away from the second frame 102. The force-bearing component 502 is tilted away from the side wall of the second frame 102. When the clamping member 704 rotates counterclockwise, the position of the clamping member 704 contacting the force-bearing component 502 changes. When the swing rod 302 reaches the horizontal state, the positioning column 704b in the clamping member 704 corresponds to the position of the clamping groove 502b. Under the push of the second elastic member 702c, the sliding body 702a drives the penetrating column 702b to drive The bending member 704a moves so that the positioning column 704b is snapped into the inner side of the snap-in groove 502b, thereby completing the positioning of the entire rocker arm 302, and making the convex shaft 501b stably located at the end end 502a-2 of the guide groove 502a. Because the force-bearing member 502 cannot be separated from the through-slide groove 101d, when the snap-in member 704 is located on the inner side of the snap-in groove 502b, the entire rocker arm 302 cannot rotate, thereby completing the locking of the entire rocker arm 302. Therefore, the insert 503 is also in a state of being stably inserted into the second cross frame 102c, thereby improving the connection stability between the first cross frame 101c and the second cross frame 102c.
[0066] Of course, this arrangement has another effect, that is, when the moving platform 400 carries the rotor brake 900 back to the distal end 302b, due to the existence of the locking mechanism 700, the swing rod 302 will not rotate immediately. When the moving platform 400 and the rotor brake 900 are completely at the distal end 302b, the moving platform 400 presses the resistance member 703, so that the resistance member 703 drives the sliding body 702a to press the second elastic member 702c. At this time, the penetrating column 702b pushes the curved member 704a, so that the positioning column 704b is pushed out of the clamping groove 502b, and the positioning of the swing rod 302 is automatically released. At this time, the gravity of the moving platform 400 and the rotor brake 900 completely acts on the distal end 302b. Therefore, the pressing force given to the swing rod 302 at the moment of lifting enables the swing rod 302 to stably pull the force-bearing member 502 through the pushing member 501, so that the inserting member 503 is separated from the second cross frame 102c.
