Description

Technical Field

[0001] This invention relates to the field of high-voltage motor technology, specifically a modular high-voltage motor. Background Technology

[0002] High-voltage motors, as core equipment in the industrial drive field, are widely used in large-scale production scenarios such as metallurgy, petrochemicals, power, and mining. Due to their high operating voltage, large load, and complex working environment, key components such as internal windings, insulation structures, and bearings are prone to aging, wear, or localized damage during long-term operation. Regular inspections and timely maintenance are necessary to ensure the safe and reliable operation of the equipment.

[0003] Currently, the casing structure of traditional high-voltage motors is mostly constructed using integral welding or one-piece casting, with components such as end covers, housings, and bases rigidly fixed together by multiple sets of bolts and pins. While this structure ensures mechanical strength and sealing performance during operation, it reveals several shortcomings in actual maintenance operations. First, when a local fault occurs inside the motor, maintenance personnel often need to disassemble almost the entire casing, sequentially removing multiple components such as the rear end cover, front end cover, and upper and lower housings to expose the faulty area. This disassembly process is time-consuming and labor-intensive, requiring specialized lifting and support tools, resulting in low maintenance efficiency. Second, frequent large-scale disassembly and assembly not only increases the labor intensity of workers but also easily leads to problems such as stripped bolts, damage to sealing surfaces, and decreased positioning accuracy, thus introducing new potential faults. Furthermore, although some existing motors have attempted to adopt a split cover structure, there is a lack of effective quick locking and positioning mechanisms between the covers. After assembly, the overall rigidity is insufficient, which easily generates vibration and noise during operation, and the sealing performance is difficult to guarantee. When disassembly is required, the covers often become stuck due to long-term heat deformation or corrosion, making it difficult to separate smoothly, further increasing the difficulty of disassembly. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows: A modular high-voltage motor includes an assembly mechanism, a locking mechanism, a top support mechanism, and a disassembly mechanism. The assembly mechanism includes an inner core, two opposing inner support frames detachably mounted on the front and rear sides of the inner core, end caps and a rear cover movably fitted onto both ends of the inner core, with one end of each inner support frame fitting against the inner wall of the end cap and the other end extending movably into the interior of the rear cover. The locking mechanism includes four sealing slide plates arranged around the outer side of the inner core and slidably connected to the inner support frames, a pad fixed to the outer side of the sealing slide plates and fitting against the inner wall of the rear cover, a wedge detachably connected between the rear cover and the pad, and four I-beams fixed around the outer side of the end caps. A movable rod fixedly passing through one side of the wedge and rotatably connected to the I-beam frame; two torsion springs fixed between the I-beam frame and the movable rod; a top support mechanism, the top support mechanism including a retaining ring fixedly connected to the inner cavity of the rear cover; multiple rubber pillars fixedly connected to the retaining ring; multiple rubber pillars respectively press-fitted to the outer side of four sealing slide plates; a disassembly mechanism, the disassembly mechanism including an opening opened on the movable rod; a cylindrical column rotatably disposed inside the opening; a pressure rod fixedly connected to the bottom of the cylindrical column; two sliding grooves respectively opened on the two side walls inside the opening; two T-bars slidably connected between two T-bars and the cylindrical column; and a spring located inside the cylindrical column and fixedly connected between the two T-bars.

[0006] By adopting the above technical solution, through the coordinated operation of the assembly mechanism, locking mechanism, support mechanism and disassembly mechanism, the modular construction of the motor housing can be achieved. The components can be quickly positioned and interlocked, and can also be disassembled individually as needed during maintenance, thereby significantly reducing the maintenance difficulty and disassembly workload, and improving on-site operation efficiency.

[0007] In a preferred embodiment, the present invention may be further configured such that the inner support frame consists of two crossbeams and a longitudinal beam, the longitudinal beam being disposed near the end cap and fixed between the two crossbeams.

[0008] In a preferred embodiment, the present invention can be further configured such that: both long sidewalls of the crossbeam are provided with a channel and a disassembly opening, the channel is located between the disassembly opening and the rear cover, the channel is adapted to be inserted into the sealing slide plate, and the length of the disassembly opening is equal to the length of the sealing slide plate.

[0009] In a preferred embodiment, the present invention can be further configured such that: the end cap is composed of a disc and four arc plates, the four arc plates are staggered with four crossbeams, and the outer wall of the arc surface is movably fitted with the inner wall of the sealing slide plate.

[0010] In a preferred embodiment, the present invention may be further configured such that the wedge is composed of a metal block and a rib, the rib being interference-fitted into the inner wall of the rear cover and fixedly connected to the metal block.

[0011] In a preferred embodiment, the present invention can be further configured such that: multiple rubber pillars are grouped in pairs, forming four groups, with the four groups of rubber pillars located outside four sealing slide plates.

[0012] In a preferred embodiment, the present invention may be further configured such that: a tool assembly is provided on the outer side of the T-bar, the tool assembly including an insertion hole opened on the movable rod, an insertion rod inserted into the insertion hole, and a rope fixed between the movable rod and the outer end of the insertion rod, the inside of the insertion hole communicating with the inside of the slide groove.

[0013] In a preferred embodiment, the present invention may be further configured such that: a support block is provided on the inner side of the movable rod, and the inner end of the support block is fixedly connected to the outer wall of the rear cover.

[0014] In a preferred embodiment, the present invention can be further configured such that: a plurality of heat dissipation fins are fixedly connected to the outer wall of the sealing slide plate, and the plurality of heat dissipation fins are arranged in groups of three, forming two groups, with the two groups of heat dissipation fins located on both sides of the pad block respectively.

[0015] In a preferred embodiment, the invention may be further configured such that the length of the heat dissipation fins is equal to the length of the sealing plate, and the heat dissipation fins are made of a high thermal conductivity metal material.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, the modular construction of the motor housing can be achieved through the coordinated cooperation of the assembly mechanism, locking mechanism, top support mechanism and disassembly mechanism. The components can be quickly positioned and interlocked, and can also be disassembled individually as needed during maintenance, thereby significantly reducing the maintenance difficulty and disassembly workload, and improving on-site operation efficiency.

[0017] 2. In this invention, the combined action of the wedge, movable rod, torsion spring and rubber column enables a firm self-locking relationship between the rear cover, sealing slide and inner support frame during assembly, ensuring structural stability during operation; while during unlocking, the elastic restoring force of the rubber column can push the rear cover to automatically detach, realizing convenient semi-automatic disassembly and further optimizing the maintenance process.

[0018] 3. In this invention, by setting a channel and a disassembly port on the crossbeam of the inner support frame, and by configuring pads and wedges on the outside of the sealing slide plate, any sealing slide plate can be independently pulled out from the corresponding disassembly port without disassembling other outer shell parts. This is particularly suitable for rapid on-site repair of locally damaged areas, effectively shortening downtime for maintenance and reducing the risk of misoperation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a modular high-voltage motor provided by the present invention.

[0024] Example 1: Combining Figures 1-8As shown, the present invention provides a modular high-voltage motor, including an assembly mechanism 100, a locking mechanism 200, a top support mechanism 300, and a disassembly mechanism 400. The assembly mechanism 100 includes an inner core 110, two inner support frames 120 arranged opposite to each other and detachably installed on the front and rear sides of the inner core 110, and end caps 130 and rear caps 140 respectively movably sleeved on both ends of the inner core 110. One end of the inner support frame 120 is attached to the inner sidewall of the end cap 130, and the other end of the inner support frame 120 extends movably into the interior of the rear cap 140. The locking mechanism 200 includes four sealing slide plates 210 arranged around the outer side of the inner core 110 and slidably connected to the inner support frame 120; a pad block 220 fixed to the outer side of the sealing slide plate 210 and in contact with the inner wall of the rear cover 140; a wedge block 230 detachably connected between the rear cover 140 and the pad block 220; four I-beams 240 fixed around the outer side of the end cover 130; a movable rod 250 fixedly passing through one side of the wedge block 230 and rotatably connected to the I-beam 240; and two torsion springs 260 fixed between the I-beam 240 and the movable rod 250. The top support mechanism 300 includes a retaining ring 310 fixedly connected to the inner cavity of the rear cover 140, a plurality of rubber pillars 320 fixedly connected to the retaining ring 310, and the plurality of rubber pillars 320 respectively press-fitted to the outside of four sealing slide plates 210. The disassembly mechanism 400 includes an opening 410 on the movable rod 250, a cylindrical column 420 rotatably disposed inside the opening 410, a pressure rod 430 fixedly connected to the bottom of the cylindrical column 420, two sliding grooves 440 respectively opened on the inner side walls of the opening 410, two T-bars 450 slidably connected between the two T-bars 450 and the cylindrical column 420, and a spring 460 located inside the cylindrical column 420 and fixedly connected between the two T-bars 450.

[0025] Furthermore, the inner support frame 120 is composed of two crossbeams 121 and a longitudinal beam 122. The longitudinal beam 122 is located near the end cover 130 and is fixed between the two crossbeams 121, thereby forming a stable rectangular support frame that can reliably clamp and position the inner core 110 from both the front and rear sides, ensuring that the overall structure is not prone to tilting or loosening during assembly and operation.

[0026] Furthermore, both long sidewalls of the crossbeam 121 are provided with a channel 1211 and a disassembly opening 1212. The channel 1211 is located between the disassembly opening 1212 and the rear cover 140. The channel 1211 is suitable for the sealing slide plate 210 to be inserted. The length of the disassembly opening 1212 is equal to the length of the sealing slide plate 210. Based on this, the sealing slide plate 210 can slide smoothly along the channel 1211 and be directionally removed from the disassembly opening 1212 when needed. This ensures the sealing performance and enables the independent replacement of a single outer shell panel, avoiding large-area disassembly.

[0027] Furthermore, the end cap 130 is composed of a disc and four arc plates, which are staggered with four crossbeams 121. The outer wall of the arc surface is in contact with the inner wall of the sealing slide plate 210, and the inner wall of the sealing slide plate 210 and the outer wall of the arc plate form a surface contact fit, thereby improving the sealing effect of the outer shell.

[0028] Furthermore, the wedge 230 is composed of a metal block 231 and a rib 232. The rib 232 is interference-fitted into the inner wall of the rear cover 140 and fixed to the metal block 231. After insertion, the wedge 230 can form an interference fit with the inner wall of the rear cover 140 through the rib 232, which enhances the locking reliability and prevents it from loosening due to vibration. At the same time, the metal block 231 provides sufficient structural strength to transmit the locking force.

[0029] Furthermore, the multiple rubber pillars 320 are arranged in pairs, forming four groups. The four groups of rubber pillars 320 are located on the outside of the four sealing slide plates 210. This allows a uniform and consistent elastic pushing force to be applied to each sealing slide plate 210, enabling the rear cover 140 and each sealing slide plate 210 to obtain a smooth disengagement force after unlocking, thereby improving the stability and controllability of the disassembly process.

[0030] Furthermore, the outer wall of the sealing slide plate 210 is fixed with multiple heat dissipation fins 700. The multiple heat dissipation fins 700 are arranged in groups of three, with two groups of three. The two groups of heat dissipation fins 700 are located on both sides of the pad block 220. Without affecting the insertion, removal and locking functions of the sealing slide plate 210, the heat dissipation area on the outer side of the shell is significantly increased, which is conducive to the rapid dissipation of the heat generated by the operation of the inner core 110 and improves the heat dissipation performance of the motor.

[0031] Furthermore, the length of the heat dissipation fin 700 is equal to the length of the sealing plate 210. The heat dissipation fin 700 is made of a high thermal conductivity metal material, which maximizes the effective length of the heat dissipation path and improves the heat conduction efficiency by using a high thermal conductivity material, making the temperature distribution on the entire surface of the sealing plate 210 more uniform and further optimizing the heat dissipation effect.

[0032] Example 2: Combination Figure 1 , 2 and Figure 7As shown, based on Embodiment 1, a tool assembly 500 is provided on the outer side of the T-bar 450. The tool assembly 500 includes an insertion hole on the body of the movable rod 250, an insertion rod 510 inserted into the insertion hole, and a rope 520 fixed between the movable rod 250 and the outer end of the insertion rod 510. The inside of the insertion hole communicates with the inside of the slide groove 440. When the T-bar 450 needs to be moved, the insertion rod 510 can be inserted into the insertion hole and extended into the slide groove 440 to separate the insertion rod 510 from the slide groove 440. The cylinder 420 and the pressure rod 430 can be easily separated from the movable rod 250. The rope 520 can prevent the insertion rod 510 from being lost. No additional special tools are needed, which improves the convenience of on-site operation.

[0033] Example 3: Combination Figure 1-2 As shown, in the above embodiment, a support block 600 is provided on the inner side of the movable rod 250. The inner end of the support block 600 is fixed to the outer wall of the rear cover 140. When separating the wedge block 230 from the rear cover 140, a small external pry bar is inserted into the top of the support block 600. Then, by using the lever principle, the wedge block 230 can be easily pried out of the rear cover 140.

[0034] Working principle and usage process of this invention: The specific steps for assembling the entire casing are as follows: During assembly, the two inner support frames 120 are first placed on the front and rear sides of the inner core 110 and clamped. Then, the end caps 130 and the rear caps 140 are respectively fitted onto the two ends of the inner core 110, so that one end of the inner support frame 120 is in contact with the inner side wall of the end cap 130 and the other end extends into the interior of the rear cap 140, thereby completing the construction of the basic frame. At this time, the four sealing slide plates 210 are respectively inserted into the channels 1211 on both sides of the crossbeam 121, and slide along the channels 1211 towards the rear cover 140 until the outer side wall of each sealing slide plate 210 forms a preliminary fit with the inner wall of the rear cover 140 through the pad 220, thereby completing the large-area coverage of the inner core 110 and improving the protection effect of the inner core 110.

[0035] Next, the personnel on site press down on the right end of the movable rod 250. The movable rod 250 drives the wedge block 230 to move into the gap between the pad block 220 and the rear cover 140. At the same time, the pressure rod 430 on the movable rod 250 abuts against the left end of the sealing slide plate 210 and further presses the sealing slide plate 210 towards the rear cover 140, so that the outer wall of the sealing slide plate 210 is tightly pressed against the retaining ring 310 and the rubber column 320. When the movable rod 250 is pressed into place, the wedge block 230 is completely inserted between the rear cover 140 and the pad block 220 and remains locked under the torque of the torsion spring 260. At this time, the end cover 130, the movable rod 250 and the rear cover 140 form a reliable interlock, and the entire outer shell structure is firmly fixed as one, which can provide good sealing and protection for the inner core 110.

[0036] When maintenance and repair of the inner core 110 are required, the on-site personnel lift the right end of the movable rod 250 upwards, and then the torsion spring 260 returns to its original shape. Through the movable rod 250, the wedge block 230 is instantly separated from the pad block 220 and the rear cover 140. The rear cover 140 loses the locking constraint of the wedge block 230. At this time, the retaining ring 310 and rubber column 320, which were originally squeezed and deformed, return to their original shape by their own elasticity and apply an outward pushing force to the rear cover 140, automatically pushing the rear cover 140 out along the axial direction of the inner core 110, thus realizing the semi-automatic detachment of the rear cover 140. After the rear cover 140 is removed, on-site personnel can directly observe the damaged area of ​​the inner core 110 through the opening 410 of the rear cover 140. If the damaged area is small and located in the area covered by a sealing slide plate 210, the sealing slide plate 210 can be slid along the clamp 1211 towards the end cover 130. When the sealing slide plate 210 moves to the disassembly opening 1212, since the length of the disassembly opening 1212 is equal to the length of the sealing slide plate 210, the sealing slide plate 210 can be pulled outward from the disassembly opening 1212, and the damaged area will be directly exposed, facilitating targeted repair. If the damaged area is large or requires a complete internal repair, further repair may be necessary. For surface inspection, the end cover 130 can be removed as a whole along the axial direction of the inner core 110. Then, all the sealing slide plates 210 can be removed one by one from the disassembly port 1212, realizing the rapid disassembly of the entire shell. During the entire disassembly and assembly process, each shell component adopts a modular design, which can be disassembled or replaced only according to the actual damaged location, without the need for large-scale disassembly of the entire shell. This not only significantly improves maintenance efficiency, but also reduces the risk of damage to other intact components caused by repeated disassembly and assembly. At the same time, with the help of the automatic pushing function of the top support mechanism 300, the process of removing the rear cover 140 is more labor-saving and faster, further optimizing the on-site operation process.

[0037] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
