[0035] To make the purpose, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0036] As one of the key equipment in the fuel system of oil chemical tankers, the technical development and application of electric deep well pumps have also received extensive attention. An electric deep well pump is a pumping system designed specifically for chemical tankers and is used to transport liquid cargo externally. The electric deep well pump has functions such as liquid cargo unloading and tank cleaning, ensuring the safety and efficiency of chemical tankers during transportation.

[0037] Figure 1 is a schematic structural diagram of the drive shaft system provided by an embodiment of the present disclosure. Combining Figure 1 , the drive shaft system of the electric deep well pump includes a drive shaft tube 100, a liquid cargo pipe 200, two flange plates 300, and multiple connecting rib plates 400. The drive shaft tube 100 and the liquid cargo pipe 200 are parallel to each other, and the drive shaft tube 100 and the liquid cargo pipe 200 are welded together through multiple connecting rib plates 400 arranged at intervals. One of the two flange plates 300 is sleeved outside one end of the drive shaft tube 100 and one end of the liquid cargo pipe 200 respectively, and is welded to one end of the drive shaft tube 100 and one end of the liquid cargo pipe 200. The other of the two flange plates 300 is sleeved outside the other end of the drive shaft tube 100 and the other end of the liquid cargo pipe 200 respectively, and is welded to the other end of the drive shaft tube 100 and the other end of the liquid cargo pipe 200.

[0038] A bearing is provided inside the drive shaft tube 100 corresponding to the connection position between the drive shaft tube 100 and the connecting rib plate 400. The bearing is used to install the drive shaft inside the drive shaft tube 100.

[0039] In order to make the bearing and the drive shaft concentric, it is required that the straightness of the inner hole of the drive shaft tube 100 meets the requirements. Therefore, when the drive shaft tube 100 is welded to the liquid cargo pipe 200, the flange plate 300, etc., the drive shaft tube 100 needs to be corrected to make the straightness of the inner hole of the drive shaft tube 100 meet the requirements.

[0040] An assembly correction device for a drive shaft system is provided in an embodiment of the present disclosure, as Figure 2 shown. The assembly correction device includes a support assembly 1 and an adjustment assembly 2. The support assembly 1 includes a platform 11 and a plurality of support units 12. The plurality of support units 12 are arranged in a row and are spaced apart on the platform 11. Some of the plurality of support units 12 are movably connected to the platform 11 and can move relative to the platform 11 along a first direction.

[0041] Figure 3 For Figure 2 the top view of, in combination with Figure 3 , the adjustment assembly 2 is located on the platform 11 and is connected to the platform 11. The adjustment assembly 2 contacts each support unit 12 respectively to adjust the position of each support unit 12 in a second direction. The second direction, the first direction, and the arrangement direction of the plurality of support units 12 are perpendicular to each other in pairs.

[0042] The above-mentioned first direction can be referred to as Figure 2 the direction a in, and the second direction can be referred to as Figure 2 the direction b in. The direction b is the direction perpendicular to the paper surface. The direction c is the arrangement direction of the support units 12 and is also the axis direction of the drive shaft tube.

[0043] When assembling the drive shaft system by using the assembly correction device provided in the embodiment of the present disclosure, since the assembly correction device includes the support assembly 1, and the support assembly 1 includes the platform 11 and a plurality of support units 12, an installation foundation can be provided for the plurality of support units 12 through the platform 11, so that each support unit 12 is initially located at the same height. At the same time, the drive shaft tube 100, etc. can be supported by the support units 12. Moreover, since some of the support units 12 are movably connected to the platform 11 and can move relative to the platform 11 along the first direction, the support height and position of the support units 12 can be changed by adjusting the support units 12, so as to adjust the height of different support parts in the drive shaft tube 100.

[0044] Moreover, since the assembly correction device further includes the adjustment assembly 2, and the adjustment assembly 2 contacts each support unit 12 respectively to adjust the position of each support unit 12 in the second direction, the position of each support unit 12 on the platform 11 can be further adjusted through the adjustment assembly 2, so as to adjust the position of different support parts in the drive shaft tube 100 within the platform 11.

[0045] That is to say, the assembly correction device provided by the embodiments of the present disclosure can not only move the drive shaft tube 100 along the first direction, but also move the drive shaft tube 100 along the second direction, so as to flexibly adjust the support part in the drive shaft tube 100, greatly improve the efficiency, and finally make the inner hole meet the requirements.

[0046] Continue to refer to Figure 3 , optionally, the support unit 12 includes two first support units 121 and a plurality of second support units 122, and the plurality of second support units 122 are located between the two first support units 121.

[0047] The two first support units 121 are respectively in one-to-one correspondence with and connected to the two flange plates 300, and the second support unit 122 is movably connected to the platform 11, and the second support unit 122 can move relative to the platform 11 along the first direction.

[0048] In the above implementation, the two first support units 121 located at the outermost edges are used to be connected to the two flange plates 300 in one-to-one correspondence, so as to support the two ends of the two flange plates 300 and the drive shaft tube 100, etc. Moreover, the two first support units 121 are set not to be movably connected to the platform 11, so that the two ends of the drive shaft tube 100 can be concentrically positioned, so as to serve as a reference for the correction of other support parts in the follow-up.

[0049] In the embodiments of the present disclosure, the positions of the second support units 122 can be set according to the layout positions of the bearings in the drive shaft tube 100. The position of each second support unit 122 exactly overlaps with the position of the bearing pre-assembled in the drive shaft tube 100. This can ensure that the bearings are coaxial.

[0050] Figure 4 For the structural schematic diagram of the first support unit, in combination with Figure 4 , optionally, the first support unit 121 includes a bottom plate 1211 and a vertical plate 1212, and the vertical plate 1212 is vertically connected to one surface of the bottom plate 1211 away from the platform 11.

[0051] One side of each vertical plate 1212 facing the other vertical plate 1212 has a first positioning flange 201 and a second positioning flange 202, and the flange plate 300 is used to be sleeved outside the first positioning flange 201 and the second positioning flange 202 and connected to the vertical plate 1212.

[0052] In the above implementation manner, the first support unit 121 is set as the bottom plate 1211 and the vertical plate 1212. In this way, the first support unit 121 can be placed on the platform 11 through the bottom plate 1211, and at the same time, the bottom plate 1211 provides an installation foundation for the vertical plate 1212. The vertical plate 1212 is used for positioning and assembling with the flange plate 300 through the first positioning flange 201 and the first positioning flange 201. At the same time, the vertical plate 1212 is used to connect with the flange plate 300 so as to support both ends of the transmission shaft tube 100 and both ends of the liquid cargo pipe 200.

[0053] Combined with Figure 1 , in the embodiment of the present disclosure, the flange plate 300 respectively has a first through hole 301 for accommodating the transmission shaft tube 100 and a second through hole 302 for accommodating the liquid cargo pipe 200.

[0054] Combined with Figure 4 , the first positioning flange 201 in the first support unit 121 is located in the first through hole 301, the first positioning flange 201 in the first support unit 121 is located in the second through hole 302, and the inside of the first positioning flange 201 is communicated with the inside of the transmission shaft tube 100, and the inside of the first positioning flange 201 is communicated with the inside of the liquid cargo pipe 200.

[0055] A plurality of connection holes are respectively provided at intervals on the outer periphery of the first positioning flange 201 and the outer periphery of the first positioning flange 201. The connection holes are used for inserting fasteners and the like so that the vertical plate 1212 can be connected to the flange plate 300 together.

[0056] Continuing to refer to Figure 4 , optionally, the first support unit 121 further includes at least one rib plate 1213. The at least one rib plate 1213 is located on the side of the vertical plate 1212 away from the flange plate 300, and each rib plate 1213 is respectively connected to the bottom plate 1211 and the vertical plate 1212.

[0057] The rib plate 1213 is used to connect with the bottom plate 1211 and the vertical plate 1212 to further increase the structural strength of the first support unit 121.

[0058] In the embodiment of the present disclosure, the rib plate 1213, the bottom plate 1211 and the vertical plate 1212 can be connected by welding. Alternatively, the rib plate 1213, the bottom plate 1211 and the vertical plate 1212 are integrally cast structural members.

[0059] Exemplarily, the rib plate 1213 is a triangular plate, and the number of rib plates 1213 is two. The two rib plates 1213 are arranged at intervals along the first direction on the two edges of the vertical plate 1212. In this way, the setting of the rib plate 1213 will neither affect the connection between the vertical plate 1212 and the flange plate 300, and at the same time can increase the support strength of the first support unit 121.

[0060] Figure 5 is Figure 3 an enlarged view of the middle part of Figure 5 , optionally, the second support unit 122 includes a support plate 1221 and a plurality of adjusting rods 1222. One end of each of the plurality of adjusting rods 1222 is movably connected to the side of the support plate 1221 facing the platform 11, the other end of the adjusting rod 1222 abuts against the platform 11, and the support plate 1221 can move relative to the adjusting rod 1222 along the length direction of the adjusting rod 1222. The length direction of the adjusting rod 1222 is the first direction.

[0061] In the above implementation, the support plate 1221 is used to be movably connected to the plurality of adjusting rods 1222, and the adjusting rods 1222 are used to abut against the platform 11, so that the support plate 1221 can move relative to the platform 11 along the length direction of the adjusting rod 1222, thereby changing the support height of the support plate 1221 to adjust the height of the transmission shaft tube 100. Moreover, the above settings can realize the movement of the second support unit 122 relative to the platform 11 along the first direction through a simple structure.

[0062] In other examples, the second support unit 122 can also be other structures. For example, a plurality of electric telescopic cylinders and a support plate connected to the electric telescopic cylinders. The electric telescopic cylinders are placed on the platform 11, and the piston rods of the electric telescopic cylinders are connected to the support plate 1221. The telescopic direction of the piston rods of the electric telescopic cylinders is the first direction. By controlling the extension length of the piston rods of the electric telescopic cylinders, the support plate 1221 can be made to move relative to the platform 11 along the first direction. It's just that this structure is relatively complex, and it is necessary to arrange signal lines for controlling the electric telescopic cylinders, etc., and the process is relatively cumbersome.

[0063] In the embodiments of the present disclosure, the support plate 1221 is threadedly connected to the adjusting rod 1222. The support plate 1221 is provided with a threaded hole, and the outer wall of the adjusting rod 1222 is provided with an external thread. The threaded hole in the support plate 1221 is in threaded cooperation with the external thread of the adjusting rod 1222. When the support plate 1221 is rotated, the support plate 1221 can be lifted or lowered relative to the platform 11, thereby changing the height of the support plate 1221.

[0064] To ensure the balance of the support plate 1221, there are four adjusting rods 1222, and the four adjusting rods 1222 are respectively inserted at the four corners of the support plate 1221. The other end of the adjusting rod 1222 supports on the platform 11.

[0065] In addition, in order to enable the adjusting rod 1222 to stably support on the platform 11, a connecting plate (not shown in the figure) or the like may be provided at the other end of the adjusting rod 1222. The connecting plate is parallel to the platform 11 and perpendicular to the adjusting rod 1222. The connecting plate can increase the contact area between the adjusting rod 1222 and the platform 11, thereby improving the support stability of the adjusting rod 1222.

[0066] Figure 6 For Figure 2 the left view of the second support unit in Figure 6 , optionally, one side of the support plate 1221 away from the platform 11 has a first support groove 1201 for accommodating the drive shaft tube 100 and a second support groove 1202 for accommodating the liquid cargo tube 200. The first support groove 1201 and the second support groove 1202 are arranged at intervals along the second direction, and the openings of the first support groove 1201 and the second support groove 1202 are arranged away from the platform 11.

[0067] The second support unit 122 further includes a gland 1223. The gland 1223 is located on the side of the support plate 1221 away from the platform 11 and is connected to the top of the support plate 1221.

[0068] One side of the gland 1223 facing the support plate 1221 has a first pressing groove 1203 and a second pressing groove 1204. The opening of the first pressing groove 1203 is opposite to and communicated with the opening of the first support groove 1201, and the opening of the second pressing groove 1204 is opposite to and communicated with the opening of the second support groove 1202.

[0069] In the above implementation manner, the first support groove 1201 is used to accommodate the drive shaft tube 100 to limit the drive shaft tube 100 so that the drive shaft tube 100 does not swing. The second support groove 1202 is used to accommodate the liquid cargo tube 200 to limit the liquid cargo tube 200 so that the liquid cargo tube 200 does not swing.

[0070] The gland 1223 is used to be connected to the support plate 1221 so as to further limit the drive shaft tube 100 and the liquid cargo tube 200, so that the drive shaft tube 100 and the liquid cargo tube 200 can be stably clamped between the support plate 1221 and the gland 1223.

[0071] Moreover, by providing the first pressing groove 1203 and the second pressing groove 1204 in the gland 1223, the first pressing groove 1203 and the first support groove 1201 can be matched to limit the entire circumference of the drive shaft tube 100. At the same time, through the cooperation of the second pressing groove 1204 and the second support groove 1202, the entire circumference of the liquid cargo tube 200 can be limited.

[0072] Optionally, the first support groove 1201, the second support groove 1202, the first pressing groove 1203, and the second pressing groove 1204 are all V-shaped grooves.

[0073] In the above implementation, the V-shaped groove can limit the drive shaft tube 100 or the liquid cargo tube 200 through its two inclined groove walls, so that the drive shaft tube 100 or the liquid cargo tube 200 will not shake. Moreover, the V-shaped groove can also support the drive shaft tube 100 or the liquid cargo tube 200 with different outer diameters.

[0074] The support plate 1221 is also provided with a plurality of weight-reducing holes 1205 arranged at intervals. The weight-reducing holes 1205 can reduce the overall weight of the support plate 1221.

[0075] Figure 7 For Figure 6 the top view of, combined with Figure 7 In the embodiment of the present disclosure, in order to facilitate the connection between the gland 1223 and the support plate 1221, a plurality of first screw holes are arranged at intervals along the second direction in the gland 1223. Correspondingly, a plurality of second screw holes are arranged at intervals along the first direction on the side of the support plate 1221 facing the gland 1223. The plurality of first screw holes and the plurality of second screw holes are in one-to-one correspondence and coaxial, and bolts are inserted into the corresponding first screw holes and second screw holes. The axial direction of the first screw hole is the first direction.

[0076] In the embodiment of the present disclosure, both the first screw holes and the second screw holes are three.

[0077] Figure 8 For Figure 2 the left view of, combined with Figure 8 Optionally, the adjusting assembly 2 includes a plurality of adjusting units 20, and the plurality of adjusting units 20 are arranged in pairs. The two paired adjusting units 20 are arranged at intervals along the second direction and are respectively located on both sides of the support unit 12.

[0078] The adjusting unit includes a top block 21 and a top rod 22. The top rod 22 is connected to the top block 21. The top rod 22 abuts against the support unit 12, and the top rod 22 can move relative to the top block 21 along the second direction.

[0079] In the above implementation, the plurality of adjusting units 20 are arranged in pairs, so that the front and rear sides of each support unit 12 (that is, Figure 8 the left and right directions in the drawing of) can be adjusted by the same pair of adjusting units 20, and then the position of the drive shaft tube 100 can be adjusted.

[0080] Moreover, the adjusting unit is set as the top block 21 and the ejector rod 22, so that the ejector rod 22 can push the supporting unit 12 to move, thereby realizing the position adjustment of the supporting unit 12. At the same time, the top block 21 can provide an installation base for the ejector rod 22 and cooperate with the ejector rod 22 to enable the ejector rod 22 to move.

[0081] Optionally, the ejector rod 22 is threadedly connected to the top block 21, and the axial direction of the ejector rod 22 is the second direction.

[0082] In the above implementation, the ejector rod 22 and the top block 21 are set to be threadedly connected. When the ejector rod 22 is rotated, the ejector rod 22 can move relative to the top block 21. Moreover, since the ejector rod 22 and the top block 21 are set to be threadedly connected, when the ejector rod 22 rotates one circle, the actual moving distance of the ejector rod 22 relative to the top block 21 is the distance of one pitch, and the moving distance is small, so that the ejector rod 22 can perform a micro-movement to improve the position control accuracy of the supporting unit 12.

[0083] In other examples, the adjusting unit 20 can also be other structures. For example, an electric telescopic rod, etc.

[0084] Figure 9 For Figure 2 the enlarged view of the middle part of Figure 9 , in the embodiments of the present disclosure, the top block 21 is a T-shaped block. Along the axial direction of the transmission shaft tube 100, both sides of the top block 21 are fixed to the platform 11 together by fasteners such as bolts.

[0085] Referring to Figure 8 again, optionally, the platform 11 is provided with a sliding groove 110, and the extending direction of the sliding groove 110 is perpendicular to the second direction, and the adjusting assembly 2 is slidably located in the sliding groove 110.

[0086] In the above implementation, arranging the sliding groove 110 in the platform 11 can enable the adjusting assembly 2 to move along the sliding groove 110, thereby adjusting the position of the adjusting assembly 2 relative to the transmission shaft tube 100 at any time.

[0087] In the embodiments of the present disclosure, there are two sliding grooves 110. All the adjusting assemblies 2 located on the first side of the supporting unit 12 are located in the first sliding groove 110. All the adjusting assemblies 2 located on the second side of the supporting unit 12 are located in the second sliding groove 110.

[0088] Combined with Figure 3 , optionally, the assembly correction device further includes a detection component 3. The detection component 3 includes a laser 31 and a measuring target 32. The laser 31 is connected to one of the first supporting units 121, and the measuring target 32 is located in the inner hole of the transmission shaft tube 100, and the measuring target 32 can move in the transmission shaft tube 100.

[0089] In the above implementation, since the assembly correction device further includes a detection component 3, the straightness of the inner hole of the drive shaft tube 100 can be detected by the detection component 3, so as to guide the positions of the respective support units 12 in turn. Finally, the positions of different support parts in the drive shaft tube 100 are adjusted by the support units 12 to make the straightness of its inner hole meet the requirements, so as to prepare in advance for the welding of the drive shaft tube 100 with the liquid cargo pipe 200 and the flange plate 300.

[0090] The laser 31 is used to emit laser light. The measurement target 32 is used to receive the laser light and convert it into an electrical signal for transmission to the control system. The control system calculates the straightness deviation of the drive shaft tube based on the received electrical signal and displays it on the display screen in real time.

[0091] During the correction process, the operator can fine-tune the support unit 12 according to the straightness deviation data on the display screen to gradually reduce the straightness deviation of the drive shaft tube 100. When the straightness deviation of the drive shaft tube 100 reaches the preset accuracy requirement, the correction work ends.

[0092] The assembly correction device provided by the present disclosure is safe, reliable, simple in structure, flexible and convenient for correction, has obvious technical advantages, and is particularly suitable for the correction of drive shaft tubes with a very large length, etc.

[0093] The following briefly introduces the working process of the assembly correction device provided by the embodiments of the present disclosure:

[0094] First, a plurality of support units 12 are arranged in a row at intervals along the axis direction of the drive shaft tube 100, and a plurality of second support units 122 are located between two first support units 121.

[0095] Then, two flange plates 300 are respectively sleeved on both ends of the drive shaft tube 100 and the liquid cargo pipe 200, and the two flange plates 300 are respectively positioned and assembled with the two first support units 121, and at the same time, the middle parts of the drive shaft tube 100 and the liquid cargo pipe 200 are supported by the second support units 122.

[0096] Next, the detection component 3 detects and records the straightness of the inner hole of the drive shaft tube 100.

[0097] Then, according to the detection result, the adjustment component 2 adjusts the positions of different support parts of the drive shaft tube 100 in the platform 11, and adjusts the height of different support parts of the drive shaft tube 100 relative to the platform 11 through the second support units 122 until the detection component 3 detects that the straightness of the inner hole of the drive shaft tube 100 meets the actual requirements, that is, the correction ends, and then the second support units 122 are fixed on the platform 11. Subsequently, the flange plates 300 can be welded to the drive shaft tube 100 and the liquid cargo pipe 200 respectively, etc.

[0098] The above are only alternative embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
