Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromechanical equipment maintenance, specifically is a high -pressure motor shaft coupling dismounting frock. BACKGROUND

[0002] The coupling is used for connecting the end of the driving shaft and driven shaft together to transmit power, and is widely used in various mechanical equipment. When the related equipment connected with the coupling is overhauled, the coupling needs to be disassembled first to facilitate further inspection. Because the motor output shaft as the driving shaft and the shaft sleeve of the coupling are matched in a large interference amount, direct disassembly requires a very large force to be applied to the coupling, and ordinary tools are not easy to operate. If a puller is used for disassembly, the hook of the puller is not firm on the coupling and the puller hooking phenomenon is prone to occur. Moreover, in the process of pulling out the coupling by the traditional puller, the stress direction of the coupling is the direction of the puller hook, and it is not axial stress along the motor output shaft direction. Because it is not axial stress, the effect of pulling out the coupling by the puller is not obvious, and many times the connecting bolts on the puller hook are twisted off, and the coupling cannot be pulled out. For example, the traditional heating method is used for disassembly, the shaft sleeve of the coupling is heated first, and then the operator uses a hand hammer to knock to disassemble the coupling. This disassembly method is complex in the disassembly process, time-consuming and laborious, and the bolt holes on the coupling wheel are easily damaged in the manual knocking process, affecting the normal use of the coupling.

Detailed Implementation

[0028] The specific embodiments disclosed herein will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0029] like Figures 1 to 5 The image shown is a disclosed exemplary embodiment of the present invention. The high-voltage motor coupling disassembly fixture 10 of the present invention includes a movable trolley 20, a lifting assembly, a hydraulic assembly, and a fixing assembly. The lifting assembly is disposed on the movable trolley 20 and includes a first lifting component. The first lifting component includes a base plate 30, a plurality of first guide posts 31, a support plate 32, and a first driving member. The first guide posts 31 are disposed on the base plate 30, and the support plate 32 has a first through hole through which the first guide posts 31 pass. The first driving member drives the support plate 32 to move along the first guide posts 31. The fixing assembly includes... The system includes a baffle 40, several lead screws 41, and a first fastener 42. Each lead screw 41 has a first end 411 and a second end 412. The first end 411 of the lead screw 41 is mounted on the baffle 40, and the second end 412 of the lead screw 41 cooperates with the first fastener 42 to fix the coupling 60. The hydraulic assembly includes a first hydraulic jack 50, which is mounted on a support plate 32. One end of the first hydraulic jack 50 abuts against the output shaft 61 of the high-voltage motor, which is fitted with the coupling 60, and the other end of the first hydraulic jack 50 abuts against the baffle 40.

[0030] The utility model discloses high -voltage motor shaft coupling dismounting frock 10 uses first hydraulic jack 50 as power output device, is used to prop up high -voltage motor output shaft 61, and sets up fixed assembly and lifting assembly simultaneously, builds first hydraulic jack 50 working environment. Specifically, first hydraulic jack 50 is located on the supporting plate 32, and the supporting plate 32 can move along the first guide column 31 under the drive of the first drive part. In the exemplary embodiment of the present disclosure, the supporting plate 32 moves up and down along the first guide column 31 under the drive of the first drive part. By adjusting the first drive part, the height of the supporting plate 32 can be controlled, and the height of the first hydraulic jack 50 is adjusted, so that the axis of the first hydraulic jack 50 and the axis of the high-voltage motor output shaft 61 are on the same horizontal line. By adjusting the angle of the hydraulic jack, the two are on the same straight line. In this way, when the first hydraulic jack 50 outputs power to push out the high-voltage motor output shaft 61, the force output by the first hydraulic jack 50 can be fully perpendicular to the high-voltage motor output shaft 61, without deviation in other directions, so that the shaft coupling 60 is not damaged, and the force effect is maximized.

[0031] In the embodiment, a fixed assembly is also provided, which includes a baffle 40, a plurality of lead screws 41 and a first fastener 42. The first end 411 of the lead screw 41 is installed on the baffle 40, and the second end 412 cooperates with the first fastener 42 to fix the shaft coupling 60. One end of the first hydraulic jack 50 abuts against the high-voltage motor output shaft 61 on which the shaft coupling 60 is sleeved, and the other end of the first hydraulic jack 50 abuts against the baffle 40. When the first hydraulic jack 50 abuts against the high-voltage motor output shaft 61 and outputs force to it, it will push the high-voltage motor output shaft 61 to move away from the first hydraulic jack 50. The shaft coupling 60 is sleeved on the high-voltage motor output shaft 61 and is in interference fit with it. Under normal circumstances, the shaft coupling 60 will be driven to move with the high-voltage motor. However, since the shaft coupling 60 is fixed by the lead screw 41 and the first fastener 42, the shaft coupling 60 temporarily forms a new whole with the lead screw 41, the baffle 40 and the first hydraulic jack 50. When the high-voltage motor output shaft 61 is pushed to move away from the first hydraulic jack 50, the shaft coupling 60 will be separated from the high-voltage motor output shaft 61, achieving the purpose of dismounting the shaft coupling 60 from the high-voltage motor output shaft 61.

[0032] In this embodiment, the first lifting assembly includes a base plate 30, and a first guide post 31 is disposed on the base plate 30. Thus, the lifting assembly, hydraulic assembly, and fixing assembly are detachably connected to the mobile trolley 20, and the base plate 30 is secured to the mobile trolley 20. The main body of the disassembly fixture, composed of the lifting assembly, hydraulic assembly, and fixing assembly, can be easily placed on any mobile trolley, realizing a modular design for the entire disassembly fixture. In other embodiments, the first guide post 31 can be directly disposed on the mobile trolley 20, and the portion of the mobile trolley 20 used to dispose of the first guide post 31 is the base plate 30 of the first lifting assembly. In this embodiment, the specific number of lead screws 41 can be configured as needed; the number of lead screws 41 can be 2, 3, 4, or even more.

[0033] For example, such as Figure 1 , 2 As shown in Figure 4, in an exemplary embodiment of this disclosure, the pallet 32 ​​is provided with a first limiting part 321 and a second limiting part 322, and the first hydraulic jack 50 is engaged between the first limiting part 321 and the second limiting part 322. One end of the first hydraulic jack 50 is provided with a piston rod, which abuts against the output shaft 61 of the high-voltage motor on which the coupling 60 is sleeved, and the other end of the hydraulic jack abuts against the baffle 40.

[0034] In this embodiment, the support plate 32 is provided with a first limiting part 321 and a second limiting part 322 along the axial direction of the first hydraulic jack 50. The first limiting part 321 and the second limiting part 322 are triangular bodies formed by baffles. The first limiting part 321 and the second limiting part 322 cooperate to hold the first hydraulic jack 50 in the middle of the support plate 32. In this embodiment, the piston rod of the first hydraulic jack 50 abuts against the output shaft 61 of the high-voltage motor, which is fitted with a coupling 60. The piston rod can easily extend into the bushing of the coupling 60, which can better push out the output shaft 61 of the high-voltage motor. If the piston rod of the first hydraulic jack 50 abuts against the baffle 40, the other end may need to be equipped with other parts to achieve the above effect.

[0035] For example, such as Figure 3 , Figure 5 As shown in the exemplary embodiment of this disclosure, the fixing assembly further includes a second fastener (not shown in the figures). The baffle 40 is provided with a plurality of sliding grooves 402, and the first end 411 of the lead screw 41 passes through the sliding grooves 402 and is fixedly connected to the baffle 40 by the second fastener (not shown in the figures). The sliding grooves 402 on the baffle 40 allow the first end 411 of the lead screw 41 to slide within the sliding grooves 402, thereby allowing the spacing between the lead screws 41 to be flexibly adjusted according to the size of the coupling 60. Once the spacing between the lead screws 41 is adjusted to the appropriate position, the second fastener is used to fix them to the baffle 40. The second fastener (not shown in the figures) can be a common mechanical part such as a nut.

[0036] For example, in the example embodiment of the present disclosure, the first fastener 42 is a first nut, and the side wall of the coupling 60 is provided with a plurality of side wall holes. The second end 412 of the lead screw 41 is screwed with the first nut after passing through the side wall holes. When the side wall of the coupling 60 is provided with side wall holes, the second end 412 of the lead screw 41 can directly pass through the side wall holes and then be screwed with the first fastener 42, i.e., the first nut. The diameter of the first nut is larger than that of the side wall holes, so that the lead screw 41 and the first nut can be clamped with the coupling 60, avoiding the coupling 60 from moving with the high-voltage motor output shaft 61.

[0037] For example, as shown in FIG. 6, in another example embodiment of the present disclosure, the first fastener 42 includes a U-shaped baffle 421 and a second nut. The U-shaped baffle 421 is provided with a plurality of second through holes 4211. The second end 412 of the lead screw 41 is screwed with the second nut after passing through the second through holes 4211. Figure 5 The U-shaped baffle 421 is used to clamp the side wall of the coupling 60, which is provided with the second through holes 4211. The second end 412 of the lead screw 41 passes through the second through holes 4211 and is screwed with the second fastener, i.e., the second nut.

[0038] In the example embodiment of the present disclosure, the fixing assembly can fix the coupling 60 on one hand, avoiding the coupling 60 from moving with the high-voltage motor output shaft 61 during the process of the first hydraulic jack 50 pushing out the high-voltage motor output shaft 61. On the other hand, after the coupling 60 is separated from the high-voltage motor output shaft 61, it will not fall to the ground due to the existence of the fixing assembly, avoiding the coupling 60 from being damaged or hurting people, and improving the safety in the operation process.

[0039] For example, as shown in FIG. 6, in another example embodiment of the present disclosure, the first fastener 42 includes a U-shaped baffle 421 and a second nut. The U-shaped baffle 421 is provided with a plurality of second through holes 4211. The second end 412 of the lead screw 41 is screwed with the second nut after passing through the second through holes 4211. Figure 1 , Figure 2As shown in the exemplary embodiment of the present disclosure, the lifting assembly comprises a second lifting assembly, which comprises a plurality of second guide columns 34 arranged on the base plate 30, a plurality of guide holes 401 arranged on the baffle plate 40 and through which the second guide columns 34 pass, and a second driving member for driving the baffle plate 40 to move along the second guide columns 34. In the embodiment, the first hydraulic jack 50 is arranged on the supporting plate 32, and the supporting plate 32 is movable up and down along the first guide column 31, thereby adjusting the height of the first hydraulic jack 50. The baffle plate 40 abuts against one end of the first hydraulic jack 50. In order to make the baffle plate 40 bear force more evenly, the second lifting assembly is arranged on the base plate 30, so that the height of the baffle plate 40 can be further adjusted after the height of the first hydraulic jack 50 is adjusted, thereby adjusting the force bearing position of the baffle plate 40. On the other hand, the first end 411 of the lead screw 41 is mounted on the baffle plate 40, and the height of the baffle plate 40 can be adjusted to enable the lead screw 41 to be horizontally connected to the coupling 60 and the baffle plate 40. When the first hydraulic jack 50 exerts force, the structure composed of the coupling 60, the lead screw 41 and the baffle plate 40 can bear force more evenly and stably.

[0040] As shown in the exemplary embodiment of the present disclosure, Figure 1 , Figure 2 As shown in the exemplary embodiment of the present disclosure, the first driving member is a third nut 33, the outer surface of the first guide column 31 is provided with threads matched with the third nut 33, the third nut 33 is threadedly connected with the first guide column 31 and located below the supporting plate 32 to press the supporting plate 32. The second driving member is a fourth nut 35, the outer surface of the second guide column 34 is provided with threads matched with the fourth nut 35, the fourth nut 35 is threadedly connected with the second guide column 34 and located below the baffle plate 40 to press the baffle plate 40. In the embodiment, the third nut 33 is used to press the supporting plate 32, the fourth nut 35 is used to press the baffle plate 40, the third nut 33 is twisted by a wrench to move upward or downward along the threads on the first guide column 31, thereby finely adjusting the height of the supporting plate 32. Similarly, the fourth nut 35 is twisted by a wrench to move upward or downward along the threads on the second guide column 34, thereby finely adjusting the height of the baffle plate 40.

[0041] In addition, in the exemplary embodiments of the present disclosure, the mobile trolley 20 is provided with a plurality of universal wheels 21 at the bottom, and the body of the mobile trolley 20 is provided with a second hydraulic jack 51. The universal wheels 21 at the bottom of the mobile trolley 20 can easily adjust the angle of the body of the mobile trolley 20, and in turn adjust the axial angle of the first hydraulic jack 50, so that the axis of the first hydraulic jack 50 is in the same straight line with the axis of the high-voltage motor output shaft 61. The body of the mobile trolley 20 is provided with the second hydraulic jack 51, which can more conveniently adjust the height of the body of the mobile trolley 20 for large-scale adjustment. After the height of the first hydraulic jack 50 is adjusted to be almost in place, the third and fourth threads are used for fine adjustment.
