Abstract
Description
Technical Field
[0001] This utility model belongs to the field of large equipment fixing technology, specifically relating to high-voltage motor fixing, and particularly to fixing structure and high-voltage motor assembly. Background Technology
[0002] Large motors are usually equipped with protective covers. Currently, most widely used motor protective covers are box-type structures. Although these box-type protective covers provide good protection for motors to a certain extent and can effectively prevent foreign objects from entering the motor and avoid personnel accidentally contacting the motor's moving parts and causing injury.
[0003] In related technologies, protective covers include a housing and an inspection port. When workers need to repair large motors, they usually only open the pre-set inspection port on the housing to carry out related work. However, the existing housing design makes its internal space relatively small. When workers enter the motor through the inspection port to carry out repair operations, they need to use various tools, which are difficult to carry and operate in real time in a small space.
[0004] Therefore, how to carry tools to repair motors in confined spaces is a technical problem that urgently needs to be solved in this field.

[0008] In one alternative embodiment, the built-in support includes a slider with balls embedded at its bottom, the balls abutting against the inner wall of the movable double track.
[0009] In one alternative embodiment, the external support includes a screw disposed within a threaded hole in the motor mounting tray; wherein the screw is configured to rotate to move it upward or downward to engage with the moving double track or to abut against the ground.
[0010] In one alternative embodiment, the bottom of the screw is provided with rollers; wherein the rollers are adapted to roll along a movable double track to the ground to support the exposed motor mounting tray.
[0011] In one optional embodiment, the surface of the roller is provided with a plurality of rubber sleeves, the outer diameter of the rubber sleeves is d, the track width is l, and d is greater than l; wherein, the screw is configured to rotate 90°, so that the inner wall of the moving double track squeezes the rubber sleeves to lock the motor fixing tray inside the protective cover.
[0012] Secondly, this disclosure also provides a high-voltage motor assembly, comprising: a fixing structure adapted to support a high-voltage motor; the fixing structure includes a protective cover having a base plate and an inspection port on one side, with symmetrical movable double tracks on the base plate; a motor fixing tray is provided inside the protective cover, and the high-voltage motor is mounted on the top surface of the motor fixing tray; a movable support assembly is provided at the bottom of the motor fixing tray; the movable support assembly includes an internal support member and an external support member, the internal support member being fixed to the bottom of the motor fixing tray, and the external support member being rotatably connected to the fixed tray, with the bottom of the external support member pressed against the movable double tracks; the internal support member is adapted to move within the movable double tracks, and the external support member is adapted to move within and outside the movable double tracks; wherein the external support member is configured to rotate to remove the pressure between itself and the inner wall of the movable double tracks, and the external support member moves along the movable double tracks to the outside of its protective cover, exposing the high-voltage motor outside the protective cover for maintenance.
[0013] In one alternative embodiment, the built-in support includes a slider with balls embedded at its bottom, the balls abutting against the inner wall of the movable double track.
[0014] In one alternative embodiment, the external support includes a screw disposed within a threaded hole in the motor mounting tray; wherein the screw is configured to rotate to move it upward or downward to engage with the moving double track or to abut against the ground.
[0015] In one alternative embodiment, the bottom of the screw is provided with rollers; wherein the rollers are adapted to roll along a movable double track to the ground to support the exposed motor mounting tray.

[0017] The beneficial effects of this utility model are that it provides a fixed structure in which a high-voltage motor is fixed relative to the moving double track by setting a movable support component inside the protective cover by an external support component. When maintenance is required, the high-voltage motor can be moved outside the protective cover by the limiting of the built-in support component and the support of the external support component, so as to achieve the effect of maintenance of the high-voltage motor outside the protective cover and solve the problem of carrying tools to maintain the motor in a narrow space.

[0035] Research has revealed the following drawbacks of existing technologies: In related technologies, protective covers include a housing and an inspection port. When workers need to inspect large motors, they usually only open the pre-set inspection port on the housing to carry out related work. However, the existing housing design makes its internal space relatively small. When workers enter the motor through the inspection port to perform maintenance operations, they need to use various tools, which are difficult to carry and operate smoothly in real time within the confined space.
[0036] Therefore, how to carry tools to repair motors in confined spaces is a technical problem that urgently needs to be solved in this field.
[0037] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] like Figures 1 to 3As shown, some embodiments provide a fixing structure, including: a protective cover 1, in which the high-voltage motor 5 is fixed inside the protective cover 1, the protective cover 1 having a base plate 2, and an inspection port 11 provided on one side of the protective cover 1, and symmetrical movable double rails 21 provided on the base plate 2; the motor fixing tray 3 can move on the base plate 2 via the movable double rails 21, and the movement allows the high-voltage motor 5 to move from inside the protective cover 1 to outside the protective cover 1, thereby allowing the high-voltage motor 5 that needs to be repaired to be moved to a spacious environment so that workers can carry out repairs using tools.
[0041] The bottom of the motor mounting tray 3 is equipped with a movable support assembly 4, which consists of two parts. One part can only move on the movable double track 21, while the other part can move on the movable double track 21 and also move outside the movable double track 21, i.e., to the ground. Specifically, the movable support assembly 4 includes an internal support member 41 and an external support member 42, which are located at opposite ends of the motor mounting tray 3 on the ground. The external support member 42 is located at the end closest to the access port 11. When the motor mounting tray 3 needs to be moved towards the access port 11, the external support member 42 moves from the movable double track 21 to the ground. The internal support member 41 is fixed to the bottom of the motor mounting tray 3.
[0042] The external support 42 is rotatably connected to the fixed tray, and the bottom of the external support 42 is pressed against the movable double track 21. It should be added that when the high-voltage motor 5 is in normal operation, it is placed inside the protective cover 1. At this time, the bottom of the external support 42 is pressed against the inner wall of the movable double track 21 to relatively fix the high-voltage motor 5. When the high-voltage motor 5 needs to be inspected, that is, when it needs to be moved from inside the protective cover 1 to outside the protective cover 1, the external support 42 is needed to ensure its bottom... The part is placed inside the movable double track 21 and does not abut against the side walls of the movable double track 21, so that it can move along the movable double track 21; the built-in support 41 is adapted to move inside the movable double track 21, and the external support 42 is adapted to move inside and outside the movable double track 21; wherein, the external support 42 is configured to rotate to remove the pressure between itself and the inner wall of the movable double track 21, and the external support 42 moves along the movable double track 21 to the outside of its protective cover 1, so that the motor fixing tray 3 is exposed outside the protective cover 1 for maintenance.
[0043] The following describes the composition of the built-in support 41. The built-in support 41 includes a slider 411. A ball bearing 412 is embedded in the bottom of the slider 411. The ball bearing 412 abuts against the inner wall of the moving double track 21. This design allows the high-voltage motor 5 to move along the moving double track 21 under a relatively small pushing and pulling force.
[0044] The following describes the specific structure of the external support component 42. The external support component 42 includes a screw 421, which is disposed within a threaded hole in the motor mounting tray 3. The screw 421 is configured to rotate and move upwards or downwards to abut against the moving double track 21 or the ground. A roller 422 is provided at the bottom of the screw 421. The roller 422 is adapted to roll along the moving double track 21 to the ground to support the exposed motor mounting tray 3. Several rubber sleeves 423 are provided on the surface of the roller 422. Initially, the rubber sleeves 423 are pressed against the inner wall of the moving double track 21, and the high-voltage motor 5 is relatively fixed. When fine-tuning is required, the screw 421 is rotated so that the rolling direction of the roller 422 is aligned with the setting direction of the moving double track 21, unlocking the relatively fixed state of the high-voltage motor 5. By pushing and pulling the motor mounting tray 3, it can be moved along the moving double track 21. When the roller 422 moves outside the moving double track 21, it needs to be adjusted. Rotate the screw 421 again to move it downwards, so that the bottom surface of the rubber sleeve 423 abuts against the ground. Continue pushing to fully expose the high-voltage motor 5 outside the protective cover 1. The diameter of the outer contour of the rubber sleeve 423 is d, and the track width is l, where d is greater than l. The screw 421 is configured to rotate 90°, so that the inner wall of the moving double track 21 squeezes the rubber sleeve 423 to lock the motor fixing tray 3 inside the protective cover 1. In summary, the external support 42 not only plays a moving role, but also plays a supporting and locking role.
[0045] Some embodiments provide a high-voltage motor assembly, including: a fixing structure adapted to support a high-voltage motor 5; the fixing structure includes a protective cover 1 having a base plate 2 and an inspection port 11 on one side, and symmetrical movable double tracks 21 on the base plate 2; a motor fixing tray 3 is provided inside the protective cover 1, and the high-voltage motor 5 is mounted on the top surface of the motor fixing tray 3; a movable support assembly 4 is provided at the bottom of the motor fixing tray 3.
[0046] The movable support assembly 4 includes an internal support member 41 and an external support member 42. The internal support member 41 is fixed to the bottom of the motor mounting tray 3, and the external support member 42 is rotatably connected to the mounting tray. The bottom of the external support member 42 is pressed against the movable double track 21. The internal support member 41 is adapted to move within the movable double track 21, and the external support member 42 is adapted to move both within and outside the movable double track 21. The external support member 42 is configured to rotate to relieve the pressure between itself and the inner wall of the movable double track 21. The external support member 42 moves along the movable double track 21 to the outside of its protective cover 1, exposing the high-voltage motor 5 outside the protective cover 1 for maintenance.
[0047] The following describes the composition of the built-in support 41. The built-in support 41 includes a slider 411. A ball bearing 412 is embedded in the bottom of the slider 411. The ball bearing 412 abuts against the inner wall of the moving double track 21. This design allows the high-voltage motor 5 to move along the moving double track 21 under a relatively small pushing and pulling force.
[0048] The following describes the specific structure of the external support component 42. The external support component 42 includes a screw 421, which is disposed within a threaded hole in the motor mounting tray 3. The screw 421 is configured to rotate and move upwards or downwards to abut against the moving double track 21 or the ground. A roller 422 is provided at the bottom of the screw 421. The roller 422 is adapted to roll along the moving double track 21 to the ground to support the exposed motor mounting tray 3. Several rubber sleeves 423 are provided on the surface of the roller 422. Initially, the rubber sleeves 423 are pressed against the inner wall of the moving double track 21, and the high-voltage motor 5 is relatively fixed. When fine-tuning is required, the screw 421 is rotated so that the rolling direction of the roller 422 is aligned with the setting direction of the moving double track 21, unlocking the relatively fixed state of the high-voltage motor 5. By pushing and pulling the motor mounting tray 3, it can be moved along the moving double track 21. When the roller 422 moves outside the moving double track 21, it needs to be adjusted. Rotate the screw 421 again to move it downwards, so that the bottom surface of the rubber sleeve 423 abuts against the ground. Continue pushing to fully expose the high-voltage motor 5 outside the protective cover 1. The diameter of the outer contour of the rubber sleeve 423 is d, and the track width is l, where d is greater than l. The screw 421 is configured to rotate 90°, so that the inner wall of the moving double track 21 squeezes the rubber sleeve 423 to lock the motor fixing tray 3 inside the protective cover 1. In summary, the external support 42 not only plays a moving role, but also plays a supporting and locking role.
[0049] In summary, by setting up a movable support assembly, the high-voltage motor is fixed relative to the movable double track inside the protective cover by external support components. When maintenance is required, the high-voltage motor can be moved outside the protective cover by the limiting of the internal support components and the support of the external support components, achieving the effect of maintaining the high-voltage motor outside the protective cover. This solves the problem of carrying tools to maintain the motor in a confined space.
