Description

[Technical field]

[0001] The invention relates to the technical field of equipment maintenance, and in particular to a mirror plate maintenance work platform and a method for adjusting the horizontality of a mirror plate using the same. [Background technology]

[0002] The mirror plate of a hydro-turbine generator is an important part of a hydro-turbine generator set. The mirror plate is annular, and one of its end faces is the working surface. The smoothness requirement is very high, equivalent to the degree of a mirror surface, so it is called a mirror plate. After the unit has been running for a period of time (a maintenance cycle), the smoothness of the mirror plate working surface decreases, and it is necessary to grind and polish the working surface to repair the mirror plate.

[0003] After the mirror plate is lifted out of the turbine generator, it needs to be placed for a long time to allow the mirror plate to be stationary before it can be inspected. At present, the mirror plate is only randomly placed in an idle place when it is stationary, which is prone to moisture, rust and slight deformation. After reinstallation, it will affect the axis of the turbine generator set, and ultimately affect the working efficiency of the turbine generator. When the mirror plate is inspected, it is necessary to keep the mirror plate level, but the ground of the inspection site is usually uneven. In the prior art, the mirror plate is usually supported by steel, plates and other padding objects, and the mirror plate is repeatedly adjusted by adding and removing padding objects and repeatedly moving the mirror plate, which prolongs the inspection time. In addition, in the process of repeatedly adjusting the mirror plate level by adding and removing padding objects and moving the mirror plate, the mirror plate will vibrate to a certain extent. After the mirror plate level is adjusted, it is necessary to wait for the mirror plate to return to a stationary state before the formal inspection work can be carried out. It can be seen that the above process leads to low efficiency of the inspection work of the mirror plate. [Summary of the invention]

[0021] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0022] 1. The mirror plate is supported on the top surface of the annular body. The top surface of the annular body supports the surface of the mirror plate, which can provide uniform support for each position of the mirror plate, which is not only convenient for maintenance personnel to inspect the mirror plate, but also can avoid local slight deformation of the mirror plate. The inner ring of the annular body can provide a spare position for installing the mirror plate grinding device. By setting a number of adjustment mechanisms connected to the corresponding adjustment columns, when there is a local level difference in the overall mirror plate, the local level of the mirror plate can be adjusted without moving the mirror plate. It not only avoids deformation or damage caused by repeatedly moving the entire mirror plate, but also can shorten the time for adjusting the level of the mirror plate compared to the method of repeatedly adjusting the level of the mirror plate by adding or removing pads, thereby improving work efficiency.

[0023] In addition, when the mirror plate is subjected to local maintenance operations, such as grinding, polishing, and repair, the mirror plate at the local maintenance operation location will vibrate. The structure in which the annular body is connected by several supporting parts can reduce the vibration effect and prevent the vibration from being transmitted to the remaining supporting parts too quickly through the corresponding supporting parts, thereby preventing the stability of the entire mirror plate from being affected.

[0024] 2. A hollow groove is provided in the support part, and the hollow groove combined with the annular body connected by several support parts can further weaken the aforementioned vibration effect.

[0025] 3. The support part of the mirror panel maintenance work platform includes a top plate, an inner plate and an outer plate. The top plate, the inner plate and the outer plate can reduce the vibration effect of the local maintenance operation on the mirror panel one by one during the local maintenance operation of the mirror panel.

[0026] 4. The connection between each two supporting parts and the adjusting column is connected through the transition plate, which can increase the contact surface between the adjusting column and the supporting part, making the overall structure of the mirror plate maintenance work platform more solid.

[0027] 5. The two opposite ends of the reinforcing plate are respectively connected to the column bodies of the two adjusting columns, which can make the overall structure of the mirror plate maintenance work platform more solid.

[0028] 6. By rotating the screw seat, the screw rod can be driven to rotate in the threaded hole, thereby adjusting the height of the corresponding adjustment column, thereby playing a role in adjusting the local levelness of the mirror plate.

[0029] 7. The motor drives the screw to rotate, and the nut moves linearly along the linear direction of the screw. The nut can adjust the height of the adjustment column through the lever movement of the tilting rod on the fulcrum rod, that is, the horizontal adjustment of the mirror plate supported on the corresponding support part is completed. The above steps adjust the horizontality of the mirror plate without directly contacting the mirror plate, which can not only reduce the vibration of the mirror plate, but also speed up the adjustment speed of the mirror plate horizontality.

[0030] 8. A method of adjusting the levelness of the mirror plate using a mirror plate maintenance work platform. By adjusting the height of the adjustment column in the mirror plate maintenance work platform, the local levelness of the mirror plate can be adjusted, which can effectively avoid damage caused by repeatedly moving the mirror plate to adjust the levelness of the mirror plate.

[0040] Embodiment 1:

[0041] like Figure 1 , Figure 2 , Figure 5 As shown, the first embodiment of the present invention provides a mirror plate maintenance work platform, including a plurality of support parts 1, a plurality of adjustment columns 2 and a plurality of adjustment mechanisms. In this embodiment, the number of the support parts 1, the adjustment columns 2 and the adjustment mechanisms are eight, and the material of the adjustment columns 2 is steel. The eight support parts 1 are connected in sequence to form an annular body 14, and the top surface 110 of the annular body 14 is a plane for supporting the mirror plate. The eight adjustment columns 2 are installed on the side of the annular body 14 away from the top surface 110 and are evenly distributed. The end of each adjustment column 2 away from the support part 1 is connected to an adjustment mechanism, so that the height of the corresponding adjustment column 2 can be adjusted by the adjustment mechanism, and then the horizontality of the mirror plate supported on the top surface 110 of the annular body 14 can be adjusted.

[0042] When in use, the mirror plate is supported on the top surface 110 of the annular body 14, and the inner circle of the annular body 14 corresponds to the inner circle of the mirror plate. The top surface of the annular body 14 supports the plate surface of the mirror plate, which can provide uniform support for each position of the mirror plate, which is not only convenient for maintenance personnel to inspect the mirror plate, but also can avoid local slight deformation of the mirror plate, and the inner circle of the annular body 14 can provide a free position for installing the mirror plate grinding device. By setting a plurality of adjustment mechanisms connected to the corresponding adjustment columns 2 respectively, when the mirror plate as a whole has a local level difference, the local level of the mirror plate can be adjusted without moving the mirror plate, which not only avoids deformation or damage caused by repeatedly moving the entire mirror plate as a whole, but also can shorten the time for adjusting the level of the mirror plate compared to the method of repeatedly adjusting the level of the mirror plate by adding or removing pads, thereby improving work efficiency.

[0043] In addition, when the mirror plate is subjected to local maintenance operations, such as grinding, polishing, and repair, the mirror plate at the local maintenance operation location will vibrate. The structure in which the annular body is connected by several supporting parts can reduce the vibration effect and prevent the vibration from being transmitted to the remaining supporting parts too quickly through the corresponding supporting parts, thereby preventing the stability of the entire mirror plate from being affected.

[0044] In this embodiment, the interior of each support portion 1 is a hollow groove 10. The hollow groove 10 combined with the annular body 14 connected by eight support portions 1 can further reduce the aforementioned vibration effect.

[0045] In this embodiment, the support part 1 includes a top plate 11, an inner plate 12 and an outer plate 13. The top plate 11 is a wooden board, and the inner plate 12 and the outer plate 13 are both I-shaped steel. The top of the top plate 11 of the support parts 1 constitutes a top surface 110, and the top plate 11 includes a first side surface 111 and a second side surface 112. The first side surface 111 and the second side surface 112 are parallel to each other and the length of the first side surface 111 is less than the second side surface 112. The first side surface 111 and the second side surface 112 are respectively connected to the opposite sides of the top of the top plate 11. The inner plate 12 is arranged in parallel with the outer plate 13, the length of the inner plate 12 is less than the outer plate 13, the top of the inner plate 12 is arranged corresponding to the first side surface 111, and the inner plate 12 is vertically connected to the top plate 11. The top of the outer plate 13 is arranged corresponding to the second side surface 112, and the outer plate 13 is vertically connected to the top plate 11, so as to form a hollow groove 10 between the top plate 11, the inner plate 12 and the outer plate 13. The opposite ends of each top plate 11 are respectively connected to the top plates 11 of two adjacent support parts 1. The opposite ends of each inner plate 12 are respectively connected to the inner plates 12 of two adjacent support parts 1. The opposite ends of each outer plate 13 are respectively connected to the outer plates 13 of two adjacent support parts 1. The top plate 11, the inner plate 12 and the outer plate 13 can reduce the vibration effect of the local maintenance operation on the mirror plate one by one during the local maintenance operation of the mirror plate.

[0046] The eight adjusting columns 2 are respectively located at the connection of the eight supporting parts 1, and each adjusting column 2 is connected to the connection of the corresponding two adjacent supporting parts 1. Specifically, in this embodiment, a transition plate 3 is also provided at the connection of the two adjacent supporting parts 1, and the transition plate 3 is an I-shaped steel; each transition plate 3 extends along the radial direction of the annular body 14 and is located on the side of the annular body 14 facing away from the top surface 110; the top of each transition plate 3 connects the outer plate 13 and the inner plate 12 of the two adjacent supporting parts 1; the bottom of each transition plate 3 is connected to one end of the corresponding adjusting column 2. The provision of the transition plate 3 can increase the contact surface between the adjusting column 2 and the supporting part 1, making the overall structure of the mirror plate maintenance work platform more solid.

[0047] In this embodiment, the mirror panel maintenance work platform also includes a reinforcing plate 4, which is a channel steel. The opposite ends of the reinforcing plate 4 are respectively connected to two adjustment columns 2, which can make the overall structure of the mirror panel maintenance work platform more solid.

[0048] In this embodiment, the adjustment mechanism includes a screw rod 51 and a screw rod seat 52 . A threaded hole is provided at one end of the adjustment column 2 away from the support portion 1 . One end of the screw rod 51 is rotatably screwed into the threaded hole, and the other end of the screw rod 51 is fixedly connected to the screw rod seat 52 .

[0049] This embodiment also provides a method for adjusting the horizontality of a mirror plate using a mirror plate maintenance work platform, comprising the following steps:

[0050] S1, provide the mirror plate maintenance work platform, jack and level measuring instrument. The jack and level measuring instrument are prior art, and technicians in this field often use the instruments for operation, so they will not be described in detail here.

[0051] S2, placing the mirror plate on the annular body 14, so that one surface of the mirror plate is supported on the top surfaces 110 of at least four support parts 1;

[0052] S3, placing a level meter corresponding to an adjustment column 2, and using the level meter to measure the level of the top surface 110 of the support part 1 opposite to the adjustment column 2. If it is confirmed that there is a height difference on the top surface 110 of the support part 1 measured, proceed to step S4;

[0053] S4, when there is a height difference, use a jack to support the measured support part 1 until the corresponding adjustment column 2 is off the ground, rotate the screw seat 52, and make the screw rod 51 rise or fall by a distance consistent with the height difference, that is, complete the horizontal adjustment of the mirror plate supported on the corresponding support part 1; when there is no height difference, move the level measuring instrument to the next adjustment column 2, and repeat step S3;

[0054] S5, repeating steps S3 to S4 until the level adjustment of the entire mirror plate is completed.

[0055] The method of adjusting the horizontality of the mirror plate by using the mirror plate maintenance work platform is to adjust the height of the adjustment column in the mirror plate maintenance work platform so as to achieve the adjustment of the local horizontality of the mirror plate. The whole process adjusts the horizontality of the mirror plate without directly contacting the mirror plate, which can not only reduce the occurrence of mirror plate vibration, but also effectively avoid damage caused by repeatedly moving the mirror plate to adjust the mirror plate level.

[0056] It can be understood that the number of the support parts 1, the adjustment columns 2, and the adjustment mechanisms is not limited to eight in the present embodiment, and in other embodiments, other numbers may be used.

[0057] It can be understood that the material of the reinforcing plate 4 is not limited to the channel steel in this embodiment, and in other embodiments, it can be an angle steel.

[0058] In other embodiments, the transition plate 3 may be omitted. In this case, the adjustment column 2 may be directly connected to the side of the outer plate 13 facing away from the top surface 110 .

[0059] In other embodiments, the reinforcing plate 4 may be omitted.

[0060] Implementation 2:

The eight support parts 1 are successively connected to form an annular body 14, and the top surface 110 of the annular body 14 is a plane for supporting the mirror plate. The eight adjustment columns 2 are installed on the side of the annular body 14 away from the top surface 110 and are evenly distributed. The end of each adjustment column 2 away from the support part 1 is connected to an adjustment mechanism, so that the height of the corresponding adjustment column 2 can be adjusted by the adjustment mechanism, and then the horizontality of the mirror plate supported on the top surface 110 of the annular body 14 can be adjusted.

[0062] When in use, the mirror plate is supported on the top surface 110 of the annular body 14, and the inner circle of the annular body 14 corresponds to the inner circle of the mirror plate. The top surface of the annular body 14 supports the plate surface of the mirror plate, which can provide uniform support for each position of the mirror plate, not only facilitating maintenance personnel to inspect the mirror plate, but also avoiding local slight deformation of the mirror plate, and the inner circle of the annular body 14 can provide a free position for installing the mirror plate grinding device. By setting a plurality of adjustment mechanisms connected to the corresponding adjustment columns 2 respectively, when the mirror plate as a whole has a local level difference, the local level of the mirror plate can be adjusted without moving the mirror plate, which not only avoids deformation or damage caused by repeatedly moving the entire mirror plate as a whole, but also shortens the time for adjusting the level of the mirror plate, thereby improving work efficiency.

[0063] In addition, when the mirror plate is subjected to local maintenance operations, such as grinding, polishing, and repair, the mirror plate at the local maintenance operation location will vibrate. The structure in which the annular body is connected by several supporting parts can reduce the vibration effect and prevent the vibration from being transmitted to the remaining supporting parts too quickly through the corresponding supporting parts, thereby preventing the stability of the entire mirror plate from being affected.

[0064] In this embodiment, the interior of each support portion 1 is a hollow groove 10. The hollow groove 10 combined with the annular body 14 connected by eight support portions 1 can further reduce the aforementioned vibration effect.

The first side surface 111 and the second side surface 112 are parallel to each other and the length of the first side surface 111 is less than the second side surface 112. The first side surface 111 and the second side surface 112 are respectively connected to the opposite sides of the top of the top plate 11. The inner plate 12 is arranged in parallel with the outer plate 13, the length of the inner plate 12 is less than the outer plate 13, the top of the inner plate 12 is arranged corresponding to the first side surface 111, and the inner plate 12 is vertically connected to the top plate 11. The top of the outer plate 13 is arranged corresponding to the second side surface 112, and the outer plate 13 is vertically connected to the top plate 11, so as to form a hollow groove 10 between the top plate 11, the inner plate 12 and the outer plate 13. The opposite ends of each top plate 11 are respectively connected to the top plates 11 of two adjacent support parts 1. The opposite ends of each inner plate 12 are respectively connected to the inner plates 12 of two adjacent support parts 1. The opposite ends of each outer plate 13 are respectively connected to the outer plates 13 of two adjacent support parts 1. The top plate 11, the inner plate 12 and the outer plate 13 can reduce the vibration effect of the local maintenance operation on the mirror plate one by one during the local maintenance operation of the mirror plate.

[0066] The eight adjusting columns 2 are respectively located at the connection of the eight supporting parts 1, and each adjusting column 2 is connected to the connection of the corresponding two adjacent supporting parts 1. Specifically, in this embodiment, a transition plate 3 is also provided at the connection of the two adjacent supporting parts 1, and the transition plate 3 is an I-shaped steel; each transition plate 3 extends along the radial direction of the annular body 14 and is located on the side of the annular body 14 facing away from the top surface 110; the top of each transition plate 3 connects the outer plate 13 and the inner plate 12 of the two adjacent supporting parts 1; the bottom of each transition plate 3 is connected to one end of the corresponding adjusting column 2. The provision of the transition plate 3 can increase the contact surface between the adjusting column 2 and the supporting part 1, making the overall structure of the mirror plate maintenance work platform more solid.

[0067] In this embodiment, the mirror panel maintenance work platform also includes a reinforcing plate 4, which is a channel steel. The opposite ends of the reinforcing plate 4 are respectively connected to two adjustment columns 2, which can make the overall structure of the mirror panel maintenance work platform more solid.
