Description

Technical Field

[0001] This invention relates to the field of maintenance of converter valve cooling systems, and in particular to a regulating device. Background Technology

[0002] In ultra-high voltage converter station DC transmission systems, the cooling system, as a crucial component of the converter valve, dissipates the heat generated during operation within the valve body to the outside of the valve hall through heat exchange between internal cooling water and heat sinks, ensuring that the thyristor operating temperature remains within the normal range. The valve-cooled main pump, as a key component of the cooling system, determines the safety and stability of the entire valve-cooling system through its safety and reliability.

[0003] A valve-cooled main pump consists of a main pump and a motor that drives it. The coaxiality between the main pump and the motor is a crucial factor affecting the safety and reliability of the valve-cooled main pump. During long-term use, misalignment can easily occur between the main pump and the motor, such as radial deviation. This means that although the motor and the main pump are at the same horizontal level and parallel to each other, they are not on the same straight line, thus affecting the safety and stability of the valve-cooled main pump.

[0004] The existing radial deviation correction method uses the main pump shaft center as a reference to adjust the position of the main pump motor. The operator adjusts two positioning threaded rods at the same time to move the motor, so that the motor and the main pump are closer to concentricity. However, manual operation is prone to asynchronous adjustment of the positioning threaded rods, which leads to the further occurrence of angular phase deviation when adjusting radial error, and further occurrence of radial error when adjusting angular phase error. The adjustment process is relatively complicated, the work efficiency is low, and the labor cost is high. Summary of the Invention

[0005] Therefore, it is necessary to provide an adjustment device to address the difficulty in adjusting the radial deviation between the motor and the main pump.

[0006] An adjusting device is used to adjust the radial deviation of a motor relative to a main pump. The motor includes two positioning members spaced apart along a first direction. The adjusting device includes a base and an adjusting module, wherein:

[0007] The adjustment module is movably mounted on the base in the vertical direction and includes a housing and a chain drive unit. The housing has three mounting holes sequentially opened along the first direction. The chain drive unit includes a linkage belt and two gear sleeve assemblies and a gear shaft assembly that are rotatably mounted in the mounting holes. The linkage belt is sleeved on the gear sleeve assembly and the gear shaft assembly.

[0008] The two gear sleeve assemblies located at both ends of the housing have abutting ends that extend out of the housing and cooperate with the motor, and one of the gear sleeve assemblies is adjustable along the first direction, while the gear shaft assembly located in the middle has an operating end that extends out of the housing.

[0009] The aforementioned adjustment device rotates the gear shaft assembly, causing the linkage belt to rotate, which in turn causes the two gear sleeve assemblies meshing with the linkage belt to rotate simultaneously. This drives the two abutment ends to rotate simultaneously, thus simultaneously propelling the motor. Compared to the previous method of relying on operators to adjust the two abutment ends simultaneously to move the motor, this avoids the situation where manual operation can easily lead to asynchronous movement of the abutment ends and the motor. Overall, it improves work efficiency and reduces labor costs.

[0010] In one embodiment, the three mounting holes include a first mounting hole, a second mounting hole, and a third mounting hole, and the housing includes a first housing and a second housing that are fitted together.

[0011] Along the first direction, the length of the first mounting hole is greater than the length of the third mounting hole;

[0012] The first housing has a first through hole and a second through hole at both ends along the first direction;

[0013] The second housing is provided with a first positioning hole, a third through hole and a second positioning hole in sequence along the first direction. The first positioning hole corresponds to and cooperates with the first through hole to form a first mounting hole. The second positioning hole corresponds to and cooperates with the second through hole to form a third mounting hole. The third through hole constitutes the second mounting hole.

[0014] In one embodiment, the gear sleeve assembly includes a sleeve, a first gear, and the abutting end, wherein the first gear is sleeved on the sleeve, the sleeve is sleeved on the abutting end, and the abutting end extends out of the housing to cooperate with the motor.

[0015] In one embodiment, the abutting end is a threaded fastener, and the inner bore of the sleeve mates with the fastening head of the threaded fastener.

[0016] In one embodiment, the first housing includes a first plate and an annular first extension wall connected to the first plate;

[0017] The chain drive unit further includes an adjusting bearing, which is sleeved in the sleeve located in the first mounting hole, located on the side of the first gear near the first through hole, and has at least one second extension wall connected to its outer side. The second extension wall has a first receiving hole, which opens on the side of the second extension wall near the first housing.

[0018] The first plate body is also provided with at least one positioning groove that penetrates its thickness, the length direction of the positioning groove is the first direction, and the groove length of the positioning groove is not less than the hole length of the first mounting hole along the first direction.

[0019] The first fastener passes through the positioning groove and connects to the first receiving hole, thus connecting the first housing and the adjusting bearing into one unit.

[0020] In one embodiment, the first extension wall has a fifth through hole extending through its thickness at one end near the adjusting bearing. The axial direction of the fifth through hole is consistent with the first direction. A second fastener passes through the fifth through hole and is connected to the adjusting bearing.

[0021] In one embodiment, the gear shaft assembly includes a drive shaft and a second gear sleeved on the drive shaft, with the portion of the drive shaft extending out of the housing serving as an operating end.

[0022] In one embodiment, the adjustment module further includes a telescopic assembly located between the housing and the base, the telescopic assembly including a telescopic rod, a limiting cone sleeve, a sleeve rod, and a locking sleeve;

[0023] The telescopic rod is movably installed inside the sleeve rod, and the side facing away from the base is connected to the housing;

[0024] The end of the sleeve rod away from the housing is connected to the base, and the inner wall of the other end is provided with an inverted conical hole;

[0025] The limiting cone sleeve is fitted onto the telescopic rod and matches the inverted conical hole, for fixing the telescopic rod inside the sleeve;

[0026] The locking sleeve is fitted onto the telescopic rod and covers the limiting cone sleeve, and is detachably connected to the outer wall of the sleeve rod, for fixing the telescopic rod, the limiting cone sleeve and the sleeve rod into one unit.

[0027] In one embodiment, it is also used in conjunction with a mounting base on which the motor is mounted. The mounting base can be magnetized, and the base has magnetic force for adhering to the mounting base.

[0028] In one embodiment, the adjustment module further includes a connecting plate, one side of which is connected to the housing and the other side of which is connected to the telescopic rod. Attached Figure Description

[0050] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0051] like Figure 1 , Figure 2 as well as Figure 3 As shown, one embodiment of the present invention provides an adjustment device 10 for adjusting the radial deviation of a motor 20 relative to a main pump. The motor 20 includes two positioning members 21 spaced apart along a first direction a. The adjustment device 10 includes a base 100 and an adjustment module 200, wherein:

[0052] The adjustment module 200 is movably mounted on the base 100 in the vertical direction. The adjustment module 200 includes a housing 210 and a chain drive unit 220. The housing 210 has three mounting holes in sequence along the first direction a. With the above arrangement, the adjustment module 200 can move up and down relative to the base 100, which makes it easy for the adjustment module 200 to move to a suitable height to adjust the radial deviation of the motor 20.

[0053] The chain drive unit 220 includes a linkage belt 221 and two gear sleeve assemblies 222 and a gear shaft assembly 223 that are rotatably mounted in the mounting holes. The linkage belt 221 is sleeved on the gear sleeve assembly 222 and the gear shaft assembly 223. In a specific configuration, the linkage belt 221 can be a chain or a conveyor belt. The inner side of the conveyor belt has teeth that mate with the gear sleeve assembly 222 and the gear shaft assembly 223.

[0054] Two gear sleeve assemblies 222 located at both ends of the housing 210 have abutment ends 2221 extending out of the housing 210 and engaging with the motor 20. One gear sleeve assembly 222 is adjustable along a first direction a. The gear shaft assembly 223 located in the middle has an operating end extending out of the housing 210. In a specific configuration, the abutment ends 2221 engage with the motor 20. Specifically, the motor 20 has two spaced-apart mating holes on both sides of its axis along the first direction a. The two abutment ends 2221 partially extend into the two mating holes on the same side, facilitating the movement of the motor 20 when the abutment ends 2221 are rotated. Through the above configuration, the distance between the two gear sleeve assemblies 222 can also be adjusted, allowing the two abutment ends 2221 to easily adapt to the distance between the mating holes.

[0055] In practical use, when the motor 20 and the main pump are at the same horizontal level and parallel to each other but not on the same straight line, if the motor 20 is located to the left of the main pump, that is, the axis of the motor 20 is located to the left of the axis of the main pump, the adjusting device 10 needs to be placed to the left of the motor 20. The abutment end 2221 is engaged with the mating hole located to the left of the axis of the motor 20 to abut against the motor 20, so as to push the motor 20 to the right, that is, drive the axis of the motor 20 to approach the axis of the main pump, so that the motor 20 and the main pump are coaxial. If the motor 20 is located to the right of the main pump, the adjusting device 10 needs to be placed to the right of the motor 20, which is the same as when the motor 20 is located to the left of the main pump.

[0056] The aforementioned adjustment device 10 rotates the gear shaft assembly 223, causing the linkage belt 221 to rotate, which in turn causes the two gear sleeve assemblies 222 meshing with the linkage belt 221 to rotate simultaneously, thereby driving the two abutment ends 2221 to rotate simultaneously, thus simultaneously driving the motor 20 to move. Compared with the previous method of relying on operators to adjust the two abutment ends 2221 to move the motor 20 at the same time, this avoids the situation where manual operation can easily lead to the abutment ends 2221 driving the motor 20 to move asynchronously, thus improving overall work efficiency and reducing labor costs.

[0057] To better secure the gear sleeve assembly 222 and the gear shaft assembly 223, in a preferred embodiment, the three mounting holes include a first mounting hole, a second mounting hole, and a third mounting hole. The housing 210 includes a first housing 211 and a second housing 212 that are fitted together. In a specific configuration, after the first housing 211 is fitted onto the second housing 212 for fixation, the first housing 211 and the second housing 212 can also have fixing holes 213 that penetrate the thickness of both. The first housing 211 and the second housing 212 are connected as a whole by bolts passing through the fixing holes 213.

[0058] Along the first direction a, the length of the first mounting hole is greater than the length of the third mounting hole;

[0059] The first housing 211 has a first through hole 2111 and a second through hole 2112 at both ends along the first direction a;

[0060] The second housing 212 is provided with a first positioning hole 2121, a third through hole 2122 and a second positioning hole 2123 in sequence along the first direction a. The first positioning hole 2121 corresponds to and cooperates with the first through hole 2111 to form a first mounting hole. The second positioning hole 2123 corresponds to and cooperates with the second through hole 2112 to form a third mounting hole. The third through hole 2122 constitutes the second mounting hole.

[0061] In a specific configuration, the first housing 211 may also have a third positioning hole along the first direction a. The third positioning hole corresponds to and cooperates with the third through hole 2122 to form a second mounting hole. The first positioning hole 2121 and the first through hole 2111, the second positioning hole 2123 and the second through hole 2112, and the third positioning hole and the third through hole 2122 are generally aligned. The two gear sleeve assemblies 222 located at both ends of the housing 210 are rotatably mounted in the first mounting hole and the third mounting hole, respectively. The gear shaft assembly 223 located in the middle is rotatably mounted in the second mounting hole. With the above configuration, the length of the first mounting hole along the first direction a is greater than the length of the third mounting hole along the first direction a, which facilitates the movement of the gear sleeve assembly 222 located in the first mounting hole, thereby changing the distance between the two gear sleeve assemblies 222.

[0062] In order to better fix the two gear sleeve assemblies 222 to the corresponding mounting holes, specifically, the gear sleeve assembly 222 includes a sleeve 2222, a first gear 2223 and an abutment end 2221. The first gear 2223 is sleeved on the sleeve 2222, the sleeve 2222 is sleeved on the abutment end 2221, and the abutment end 2221 extends out of the outer shell and cooperates with the motor 20. In a specific configuration, one side of each of the two sleeves 2222 is rotatably fixed within the corresponding first positioning hole 2121 and second positioning hole 2123. The sleeve 2222 located within the first positioning hole 2121 is movable within the first positioning hole 2121 along the first direction a. Specifically, the two sleeves 2222 and the corresponding first positioning hole 2121 and second positioning hole 2123 can be transition-fitted, or the sleeve 2222 located within the second positioning hole 2123 can be interference-fitted to the second positioning hole 2123, and the sleeve 2222 located within the first positioning hole 2121 can be transition-fitted to the first positioning hole 2121. Alternatively, positioning bearings 2224 are distributed on both sides of the first gear 2223 of the two sleeves 2222. The positioning bearings 2224 are sleeved on the sleeves 2222 to fix the first gear 2223 and prevent the first gear 2223 from moving axially along the sleeves 2222. The size of the positioning bearing 2224 located in the first mounting hole and near the first housing 211 is not smaller than the size of the first through hole 2111. The size of the positioning bearing 2224 located in the first mounting hole and near the second housing 212 is not smaller than the size of the first positioning hole 2121. When the sleeve 2222 in the first positioning hole 2121 is clearance-fitted with the first positioning hole 2121, it is convenient for the sleeve 2222 to move in the first positioning hole 2121 along the first direction a. The size of the positioning bearing 2224 located in the third mounting hole and near the first housing 211 is not smaller than the size of the second through hole 2112. The size of the positioning bearing 2224 located in the third mounting hole and near the second housing 212 is not smaller than the size of the second positioning hole 2123. The other ends of the two sleeves 2222 extend out of the corresponding first through hole 2111 and second through hole 2112, so that the two sleeves 2222 are distributed and sleeved on the two abutment ends 2221.

[0063] To facilitate the movement of the motor 20 driven by the abutment end 2221, more specifically, the abutment end 2221 is a threaded fastener, and the inner hole shape of the sleeve 2222 matches the fastening head of the threaded fastener. In a specific configuration, the motor 20 can also be placed on a support platform 30. Two side plates 31, spaced apart along the first direction a, are connected to opposite sides of the support platform 30. Each side plate 31 has a threaded through hole, through which the threaded fastener passes and engages with the mating hole on the motor 20. The two mating holes of the motor 20 along the first direction a can be threaded holes, facilitating engagement with the threaded fastener portion extending into the mating hole. When the threaded fastener is rotated, it rotates forward, thereby pushing the motor 20, which abuts against the threaded fastener, to move.

[0064] In order to realize the gear sleeve assembly 222 located in the first mounting hole along the first direction a, more specifically, the first housing 211 includes a first plate 2113 and an annular first extension wall 2114 connected to the first plate 2113;

[0065] The chain drive unit 220 also includes an adjusting bearing 224, which is sleeved in the sleeve 2222 located in the first mounting hole. The adjusting bearing 224 is located on the side of the first gear 2223 near the first through hole 2111, and at least one second extension wall 2241 is connected to the outside of the adjusting bearing 224. The second extension wall 2241 has a first receiving hole, which opens on the side of the second extension wall 2241 near the first housing 211. In a specific configuration, there are two second extension walls 2241, and the two second extension walls 2241 are symmetrically arranged about the adjusting bearing 224. When the first gear 2223 has positioning bearings 2224 on the left and right sides, the adjusting bearing 224 is located between the first housing 211 and the positioning bearing 2224 near the first housing 211.

[0066] The first plate 2113 is also provided with at least one positioning groove 2115 that penetrates its thickness. The length direction of the positioning groove 2115 is the first direction a, and the groove length of the positioning groove 2115 is not less than the length of the first mounting hole along the first direction a. In a specific setting, the number of positioning grooves 2115 is two, which matches the number of the second extension arms, and the two positioning grooves 2115 are symmetrically arranged about the first through hole 2111.

[0067] The first fastener 400 passes through the positioning groove 2115 and connects to the first receiving hole, thus integrating the first housing with the adjusting bearing 224. In a specific configuration, the first fastener 400 can pass through the positioning groove 2115 and be fixed to the first receiving hole. The first fastener 400 can be a bolt, threaded rod, etc. With the above configuration, the first fastener 400 moves along the first direction a within the positioning groove 2115, causing the adjusting bearing 224 to move along the first direction a, thereby moving the sleeve 2222 along the first direction a, thus adjusting the distance between the two sleeves 2222.

[0068] To secure the sleeve 2222 after the spacing has been adjusted, more specifically, a fifth through hole penetrating its thickness is provided at the end of the first extension wall 2114 near the adjusting bearing 224. The axial direction of the fifth through hole is aligned with the first direction a. A second fastener 300 passes through the fifth through hole and connects to the adjusting bearing 224. In specific configurations, the second fastener 300 can be a bolt, threaded rod, etc. With the above configuration, when facing two mating holes with different spacings, the adjusting bearing 224 can drive the sleeve 2222 located in the first positioning hole 2121 to move along the first direction a, so that the two abutting ends 2221 can smoothly engage with the two mating holes of the motor 20. Then, the second fastener 300 connects the first extension wall 2114 and the adjusting bearing 224 as one unit, preventing the sleeve 2222 from continuing to sway left and right.

[0069] To better secure the gear shaft assembly 223 to the second mounting hole, specifically, the gear shaft assembly 223 includes a drive shaft 2231 and a second gear 2232 sleeved on the drive shaft 2231. The portion of the drive shaft 2231 extending out of the housing serves as the operating end. In a specific configuration, one side of the drive shaft 2231 is rotatably fixed within the third positioning hole, while the other side extends out of the third through hole 2122 to become the operating end. A wrench drives the operating end to rotate, causing the second gear 2232 to drive the linkage belt 221, thereby rotating the sleeve 2222. The threaded fastener can be used to rotate and drive the motor 20 to move; or one side of the drive shaft 2231 can be rotatably fixed in the third positioning hole, and the other side of the drive shaft 2231 can be transitionally fitted with the third through hole 2122, or the second gear 2232 on the drive shaft 2231 can be provided with a positioning bearing 2224 on the side near the third through hole 2122, the positioning bearing 2224 is sleeved on the drive shaft 2231 and abuts against the third through hole 2122, and the size of the positioning bearing 2224 located in the second mounting hole is not smaller than the size of the third through hole 2122.

[0070] Combination Figure 4 As shown, in order to enable the adjustment module 200 to be movably disposed on the base 100 in the vertical direction, in a preferred embodiment, the adjustment module 200 further includes a telescopic component 230, which is located between the housing 210 and the base 100. The telescopic component 230 includes a telescopic rod 231, a limiting cone sleeve 232, a sleeve rod 233, and a locking sleeve 234.

[0071] The telescopic rod 231 is installed inside the sleeve rod 233 in a way that allows it to move up and down, and the side of the telescopic rod 231 facing away from the base 100 is connected to the housing 210.

[0072] The end of the sleeve rod 233 away from the housing 210 is connected to the base 100, and the inner wall of the other end of the sleeve rod 233 is provided with an inverted conical hole;

[0073] The limiting cone sleeve 232 is sleeved on the telescopic rod 231 and matches the inverted cone hole, and is used to fix the telescopic rod 231 inside the sleeve 233;

[0074] The locking sleeve 234 is sleeved on the telescopic rod 231 and covers the limiting cone sleeve 232. It is detachably connected to the outer wall of the sleeve rod 233. It is used to fix the telescopic rod 231, the limiting cone sleeve 232 and the sleeve rod 233 into one unit. In specific settings, the locking sleeve 234 and the outer wall of the sleeve rod 233 can be threaded. With the above settings, when the height of the adjustment module 200 needs to be increased, unscrew the outer wall of the locking sleeve 234 and the sleeve rod 233, pull the telescopic rod 231 upward, and the limiting cone sleeve 232 will separate from the sleeve rod 233, thus raising the height of the telescopic rod 231. After the height is adjusted, push the locking sleeve 234 downward, causing the locking sleeve 234 to move the limiting cone sleeve 232 downward. When the limiting cone sleeve 232 moves downward to match the inverted conical hole, tighten the locking sleeve 234 and the sleeve rod 233 to fix the telescopic rod 231. When the height of the adjustment module 200 needs to be decreased, unscrew the outer wall of the locking sleeve 234 and the sleeve rod 233, and move the telescopic rod 231 downward. The fixing method of the telescopic rod 231 remains unchanged. The above-mentioned telescopic component 230 facilitates the adjustment of the height of the adjustment module 200, and facilitates the adjustment module 200 to adjust the coaxiality of motors 20 at different heights or located at different heights.

[0075] Combination Figure 5 As shown, to ensure the stability and secure use of the adjusting device 10, in a preferred embodiment, the adjusting device 10 is also used in conjunction with a mounting base 500. The mounting base 500 is equipped with a motor 20 and can be magnetized. The base 100 has magnetic force for adsorption onto the mounting base 500. In a specific configuration, the motor 20 can be mounted on a support platform 30, which is mounted on the mounting base 500. The mounting base 500 is generally made of iron plate. The base 100 can be a magnetic base, comprising a first magnetic conductor 110 and a second magnetic conductor 120. The first magnetic conductor 110 and the second magnetic conductor 120 can be cast iron. The first magnetic conductor 110 has a first through slot, and the second magnetic conductor 120 has a second through slot. When the first magnetic conductor 110 and the second magnetic conductor 120 are engaged, the first through slot and the second through slot are paired one-to-one. An installation through hole 130 should be formed. An electrical soft iron 140 coaxial with the installation through hole 130 is inlaid on the inner surface of the installation through hole 130. The permanent magnet 160 is located at the axis of the installation through hole 130 and is rotatably fixed in the inner cavity of the electrical soft iron 140 layer. A partition 150 is provided at the solid mating point of the first magnetic conductor 110 and the second magnetic conductor 120. The partition 150 can be a brass plate. The inner end face of the brass plate is flush with the inner surface of the electrical soft iron 140 layer. A rotating handle 170 extending out of the installation through hole 130 can be provided on one side of the permanent magnet 160.

[0076] In practical use, when the rotating handle 170 drives the permanent magnet 160 to rotate to a horizontal position, the permanent magnet 160, the brass plate, the first magnetic conductor 110, and the second magnetic conductor 120 form a closed magnetic field circuit, and the base 100 can be firmly attached to the mounting base 500, making the entire adjustment device 10 stable and secure during use; when the rotating handle 170 drives the permanent magnet 160 to rotate to a vertical position, the magnetic lines of force form closed circuits in the first magnetic conductor 110 and the second magnetic conductor 120 respectively, and the adjustment device 10 can be easily removed.

[0077] To facilitate the fixing of the telescopic component 230, the adjustment module 200 further includes a connecting plate 240. One side of the connecting plate 240 is connected to the housing 210, and the other side is connected to the telescopic rod 231. By connecting the telescopic component 230 to the adjustment module 200 using the connecting plate 240, the adjustment module 200 can be appropriately protected from impact during adjustment of the telescopic rod 231.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
