Description

Technical Field

[0001] This invention relates to the field of motor flange disassembly and assembly equipment, specifically to a disassembly and assembly equipment for a motor coupling flange in a mine. Background Technology

[0002] Currently, in the mining industry, large electric motors are used as the power source for the entire mine hoisting and ore conveying system. These large motors are generally connected to the actuators via couplings. Due to the relatively large size of the motors, the size and weight of the matching couplings are also correspondingly increased. In actual production, due to the limited space in underground mines and the impossibility of having overhead cranes, the disassembly and replacement of couplings can only be done manually. This method is inefficient, difficult, and labor-intensive. Furthermore, the limited space in underground mines makes it extremely inconvenient to operate with multiple people for handling or disassembly.

[0003] To address the aforementioned issues and facilitate disassembly and assembly by reducing labor intensity, patent CN218194922U discloses an auxiliary disassembly and assembly device for heavy-duty Y-filter flange covers. This device utilizes a height adjustment component and a tilt adjustment component to facilitate the connection between the connecting mechanism and the Y-filter flange cover, thereby avoiding the safety risks associated with suspending the Y-filter flange cover in the air during operation. It also facilitates the disassembly and reassembly of the Y-filter flange cover, thus assisting in its disassembly and assembly while reducing the difficulty, danger, and labor intensity, effectively reducing the workload of workers. However, in this technology, the tilt angle between the upper base and the inclined base is adjusted using a tilt adjustment component. Due to the single-sided hinge, the adjustment angle of the tilt adjustment component is limited, resulting in a small adjustment range. This makes it difficult for the coupling flange to adapt to different operating conditions and also reduces its accuracy under certain conditions. Furthermore, in this technology, the support component can only tilt to receive the flange in one horizontal direction, so the corresponding flange is installed in a vertical or tilted position. However, in the installation process of coupling flanges for underground mine motors, the motor is basically installed horizontally, so the installation direction of the coupling flange is horizontal. Therefore, the above-mentioned auxiliary disassembly and assembly device cannot be applied to the conventional disassembly and assembly work of coupling flanges. Summary of the Invention

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this invention is to provide a flange disassembly and assembly device for underground motor couplings. This flange disassembly and assembly device can effectively reduce the labor intensity of disassembling and assembling flanges, and also facilitates the adjustment of the flange installation position.

One end of the two-section universal rod is screwed into the nut sleeve by a thread, and the connecting operating ring is located on the outer side of the end of the installation channel away from the hinge seat.

[0009] Furthermore, the mounting base is provided with mounting steps at both ends of the mounting channel, and the limiting retaining ring is installed on the mounting steps.

[0010] Furthermore, the jacking device includes a telescopic hydraulic cylinder, which is mounted on the hinge seat and its telescopic end moves through the hinge seat; an abutment seat is hinged to the telescopic end of the telescopic hydraulic cylinder; a sliding seat is slidably mounted on the other end of the telescopic hydraulic cylinder, and a rotating shaft is provided on both sides of the sliding seat, with a slider fitted on each rotating shaft, and the slider is slidably mounted on the slide groove of the lifting moving frame.

The outward end of the telescopic jacking rod moves through the hinged seat and is hinged to the jacking head.

[0012] Furthermore, the clamping device includes a rotating base, a pair of clamping arms, and an adjusting screw. Each pair of clamping arms is slidably mounted in a sliding groove at the outward end of the rotating base. The threads on both ends of the adjusting screw have opposite directions.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] See Figures 1 to 7 This application provides a flange disassembly and assembly device for underground motor couplings, including a moving platform 100, a space adjustment device 200, a clamping device 300, and a pushing device 400; the moving platform 100 is provided with a slidable lifting moving frame 110 and a drive mechanism 120 for driving the lifting moving frame 110 to slide relative to the moving platform 100; the output end of the lifting moving frame 110 is capable of lifting and lowering; the space adjustment device 200 includes a hinge seat 210, a plurality of adjustment seats 220, and at least three sets of universal adjustment rods 230; one end of all the universal adjustment rods 230 is hinged to the hinge seat 210 and the universal adjustment rods 230 are capable of surrounding The lifting frame 110 rotates relative to the hinge seat 210 about its own axis. All the adjusting seats 220 are rotatably mounted on the lifting frame 110. The other end of all the universal adjusting rods 230 are screwed into the adjusting seat 220. The clamping device 300 is detachably mounted on the hinge seat 210 for clamping the coupling flange. The pushing device 400 is mounted on the hinge seat 210. The telescopic end of the pushing device 400 can cooperate with the clamping device 300 to push the coupling flange off the motor spindle. Alternatively, the lifting frame 110 can push the coupling flange into and mount it on the motor spindle through the clamping device 300.

[0033] In this device, removing the coupling flange requires the clamping device 300 and the pushing device 400 to work together, which is very simple and convenient. When it is necessary to push the coupling flange onto the motor spindle, the drive mechanism 120 drives the lifting and moving frame 110 to push the coupling flange onto the spindle, at which point the ground applies a reaction force to the moving platform 100. In addition, the main function of the space adjustment device 200 is to use multiple universal adjustment rods 230 to adjust the spatial orientation of the hinge seat 210, thereby adjusting the orientation of the coupling flange held by the clamping device 300. This can adapt to different disassembly and assembly conditions and improve the convenience of use.

[0034] See Figure 1 and Figure 2 It should be noted that, for ease of movement, casters are provided on the mobile platform 100 in this application. To adapt to ground with varying flatness, adjustable screws are provided at each of the four corners of the mobile platform 100. During use, the entire mobile platform 100 needs to be completely lifted off the ground to ensure its stability and flatness, facilitating accurate alignment of the coupling flange with the motor spindle and improving installation convenience. Furthermore, the lifting mobile frame 110 in this application includes a main frame 112, a sliding frame 113 slidably mounted on the main frame 112, and a lifting mechanism 114 for adjusting the lifting of the sliding frame 113. The lifting mechanism 114 can be a motor screw structure or a flange screw structure; in some embodiments, a motor-driven chain lifting method can also be used. The other ends of the multiple universal adjusting rods 230 are mounted on the sliding frame 113 via adjusting seats 220. In one embodiment of this application, the drive mechanism 120 can be a motor lead screw structure, which is connected to the main frame 112 by a lead screw nut. Meanwhile, the main frame 112 can be slidably mounted on the mobile platform 100 by a slider.

[0035] The equipment for disassembling and assembling the motor coupling flange in this mine adopts a mobile platform 100 design, which facilitates workers in moving the coupling flange to a suitable position for installation, improving installation convenience. The lifting and moving frame 110 can be raised and lowered, allowing workers to adjust the height of the coupling flange. Multiple sets of universal adjusting rods 230, in conjunction with adjusting seats 220, allow workers to adjust the extension length of each universal adjusting rod 230 as needed, thereby adjusting the orientation of the hinge seat 210 to accommodate different installation angles. Simultaneously, the interaction of multiple sets of three universal adjusting rods 230 allows for fine-tuning of the height of the hinge seat 210 within a certain range. A clamping device 300 is used to hold and restrict the coupling flange, facilitating its positioning and fixing, which is beneficial for disassembly and assembly. A pushing device 400, in conjunction with the clamping device 300, can push the coupling flange off the motor main shaft, improving disassembly efficiency. The method of using the drive mechanism 120 to drive the lifting and moving frame 110 to move horizontally facilitates the later insertion of the coupling flange into the motor main shaft, reducing the trouble and labor intensity of manual operation.

[0036] See Figures 1 to 3 Because the clamping device 300 clamps the coupling flange in this application, and multiple sets of three universal adjustment rods 230 extend outward to support the clamping device 300, this design can easily make the center of gravity of the entire disassembly and assembly device unstable. Therefore, in one embodiment of this application, to ensure the stability of the disassembly and assembly equipment, the mobile platform 100 has storage mounting positions 130 on both sides of one end of the space adjustment device 200, and each storage mounting position 130 is hinged with a support arm 140, which can swing outward. This retractable design facilitates the transportation of the entire disassembly and assembly equipment and allows it to adapt to different usage environments. To improve support capacity, a detachable support plate is provided on the outward end of the support arm 140. In some embodiments, to adapt to different ground levels, an adjustable screw is provided on the outward end of the support arm 140, with the support plate hinged to the lower end of the screw, and an adjusting nut that cooperates with the screw is provided on the support arm 140.

[0037] See further Figures 1 to 3When the coupling flange is pushed into the motor spindle, it is relatively difficult to provide sufficient reaction force by relying solely on the friction between the support arm 140 and the moving platform 100 itself and the ground. Therefore, in one embodiment of this application, in order to ensure that the drive mechanism 120 can drive the lifting moving frame 110 to move horizontally and push the coupling flange on the clamping device 300 onto the motor spindle, a storage groove 150 is provided on both sides of the moving platform 100. An opening 160 is connected to the end of the storage groove 150 away from the space adjustment device 200. A limiting seat 170 is slidably installed in the storage groove 150, and a limiting arm 180 is connected to the limiting seat 170. The limiting arm 180 slides into the storage groove 150 along with the limiting seat 170. A through hole 190 is provided on the side wall of the moving platform 100 located at the opening 160. A locking hole 171 that cooperates with the through hole 190 is provided on the limiting seat 170. A limiting pin 191 is movably inserted into the through hole 190 and can be inserted into the locking hole 171. A limiting tip 181 is provided downward on the outward end of the limiting arm 180. In this embodiment, the outward-extending end of the limiting arm 180 abuts against the ground or a fixed structure. This allows the drive mechanism 120 to provide sufficient reaction force when driving the lifting and moving frame 110 to translate, preventing the moving platform 100 from slipping relative to the ground and failing to provide sufficient reaction force to push the coupling flange onto the motor spindle. During use, the limiting arm 180 is simply pulled out, allowing the limiting seat 170 to move to the opening 160. The limiting pin 191 then passes through the through hole 190 and the locking hole 171 to lock the relative positions of the limiting seat 170 and the opening 160, preventing the limiting arm 180 from retracting into the storage slot 150 when subjected to ground reaction force. When not in use, simply pulling out the limiting pin 191 allows the limiting seat 170 to move relative to the opening 160 and the storage slot 150, enabling the limiting seat 170 to retract into the storage slot 150. To prevent the limiting arm 180 from sliding out of the receiving slot 150 during transportation, a locking hole 171 is also provided on the outward end of the limiting arm 180, which can be locked relative to the opening 160 using the aforementioned limiting pin 191. It should be further noted that in the above embodiment, the main purpose of the limiting tip 181 is to allow it to be inserted into the rock strata on the roadway surface during use, thereby providing sufficient reaction force.

[0038] See further Figure 1 , Figure 2 , Figure 4 and Figure 5To reduce the difficulty of adjustment and provide sufficient support, the universal adjustment rod 230 in this application is provided in three sets. The three sets of universal adjustment rods 230 are evenly distributed on the hinge seat 210, and the end of the three sets of universal adjustment rods 230 connected to the adjustment seat 220 is extended outward, which can improve the overall support force of the three sets of universal adjustment rods 230. Furthermore, to reduce the structural complexity of the universal adjustment rod 230, in one embodiment of this application, the universal adjustment rod 230 includes a two-section universal rod 231 and a connecting seat 232. The connecting seat 232 is hinged to the hinge seat 210. A connecting cylinder 233 is provided at one end of the connecting seat 232. The two-section universal rod 231 is rotatably installed in the connecting cylinder 233. An annular groove 234 is provided at one corresponding end of the two-section universal rod 231. A detachable limiting ring 235 is provided at the port of the connecting cylinder 233. The limiting ring 235 is locked in the annular groove 234. The other ends of the two-section universal rod 231 are screwed into the adjustment seat 220. The design of the two-section universal rod 231 is mainly to facilitate the simultaneous rotation of the two-section universal rod 231 relative to the adjusting seat 220 while also providing its own connection support, achieving two goals at once; at the same time, the structure of the two-section universal rod 231 is relatively simple. In this application, since the adjusting seat 220 can be rotatably mounted on the lifting frame 110, and the two-section universal rod 231 can also rotate relative to the adjusting seat 220, the extension amount of the two-section universal rod 231 relative to the adjusting seat 220 can be adjusted by rotating the adjusting seat 220, thereby adjusting the angle of the end of the two-section universal rod 231 connected to the hinge seat 210, realizing the tilt angle adjustment of the corresponding side of the hinge seat 210. In the actual adjustment process, it is generally necessary to adjust the relative extension amount of both sets of two-section universal rods 231 relative to the adjusting seat 220 simultaneously.

[0039] It should be noted that the connecting seat 232 and the hinge seat 210 are connected by a ball joint. This type of hinge is mainly to accommodate the different spatial orientations of the hinge seat 210. The fit between the limiting ring 235 and the ring groove 234 is primarily intended to allow the two-section universal rod 231 to rotate relative to each other while simultaneously locking in position with the connecting seat 232, preventing them from coming loose.

[0040] See Figure 6In the above embodiments, the adjusting seat 220 and the lifting frame 110 can only rotate relative to each other. Simultaneously, it needs to provide an axial force along the two-section universal joint 231 to achieve the extension and retraction of the two-section universal joint 231 relative to the adjusting seat 220. To achieve this, in one embodiment of this application, the adjusting seat 220 includes a mounting base 221, a nut sleeve 222, and a connecting operating ring 223 connected to one end of the nut sleeve 222. The mounting base 221 is mounted on the lifting frame 110, and an mounting channel 224 is provided on the mounting base 221. The nut sleeve 222 is rotatably mounted within the mounting channel 224, and both ends of the mounting channel 224 are provided with limiting retaining rings 225. One end of the two-section universal joint 231 is screwed into the nut sleeve 222. The mounting base 221 and the lifting frame 110 can be connected and fixed with screws, facilitating later disassembly and replacement and improving convenience. The nut sleeve 222 and the mounting channel 224 can only rotate relative to each other. Therefore, limiting rings 225 at both ends of the mounting channel 224 are needed to restrict the position of the nut sleeve 222 within the mounting channel 224. In this application, the connecting operating ring 223 is fixedly connected to one end of the nut sleeve 222, which facilitates synchronous rotation. The connecting operating ring 223 is positioned on the outer side of the mounting channel 224 away from the hinge seat 210. This arrangement provides sufficient space for operators to adjust the extension and retraction of the two-section universal rod 231 relative to the nut sleeve 222.

[0041] Furthermore, in the improved embodiment described above, to better install the retaining ring 225, the mounting base 221 is provided with mounting steps at both ends of the mounting channel 224, and the retaining ring 225 is mounted on the mounting steps. Additionally, in some embodiments, the retaining ring 225 may consist of two half-rings, which facilitates installation and disassembly.

[0042] See further Figure 1 , Figures 4 to 6To better eject the coupling flange from the motor spindle, in one embodiment of this application, the pushing device 400 includes a telescopic hydraulic cylinder 410. The telescopic hydraulic cylinder 410 is mounted on the hinge seat 210, with its telescopic end moving through the hinge seat 210. An abutment seat 420 is hinged to the telescopic end of the telescopic hydraulic cylinder 410. A sliding seat 430 is slidably mounted on the other end of the telescopic hydraulic cylinder 410. Rotating shafts are provided on both sides of the sliding seat 430, and sliders 440 are fitted onto each rotating shaft. The sliders 440 are slidably mounted on the sliding groove 111 of the lifting and moving frame 110. The telescopic hydraulic cylinder 410 applies a pushing force, while the clamping device 300 restricts the position of the coupling flange, allowing the coupling flange to move only along the end direction of the motor spindle until it is completely ejected from the motor spindle. In some embodiments, the telescopic hydraulic cylinder 410 can be mounted solely on the hinge seat 210. This allows the telescopic hydraulic cylinder 410 to swing spatially with the hinge seat 210, accommodating large-angle orientation adjustments of the hinge seat 210. However, in this application, the telescopic hydraulic cylinder 410 is also connected to the lifting frame 110 via a sliding seat 430. The main purpose of this connection is to leverage the rigidity of the telescopic hydraulic cylinder 410 to pull the hinge seat 210, enabling the hinge seat 210 to provide greater support for the coupling flange and simultaneously reducing the diameter of the two-section universal joint 231. Furthermore, in the above embodiments, the sliding seat 430 and the telescopic hydraulic cylinder 410 can only slide within an effective distance. Several locking positions can be provided between the sliding seat 430 and the telescopic hydraulic cylinder 410 to accommodate the pulling force requirements of different working conditions.

[0043] In the above embodiments, since the thrust is provided by the telescopic hydraulic cylinder 410, a hydraulic system is required. This system must include a hydraulic pump, hydraulic tank, hydraulic pipes, and multiple corresponding valves and pipelines. Therefore, the entire hydraulic system is relatively heavy, which is detrimental to the handling and relocation of the entire disassembly and assembly equipment. See also... Figure 7Therefore, in one embodiment of this application, the jacking device 400 includes a base 450, a jacking motor 460, a turbine 470, and a jacking head 480. The base 450 is mounted on a hinged seat 210, the jacking motor 460 is mounted on the base 450, and the turbine 470 is mounted on the output end of the jacking motor 460. A telescopic jacking rod 490, capable of engaging with the turbine 470, is provided on the base 450. The outward end of the telescopic jacking rod 490 movably passes through the hinged seat 210 and is hinged to the jacking head 480. In this application, the telescopic jacking rod 490 is designed similarly to a worm gear, which, in conjunction with the turbine 470, can achieve a large torque output, suitable for outputting a large jacking force. In this application, the base 450 is a box-like structure, with the turbine 470 and the telescopic jacking rod 490 both mounted on the inner cavity of the base 450, while the jacking motor 460 can be mounted on the outer shell of the base 450. In this application, to prevent the telescopic rod 490 from swaying, a sliding hole is provided on the base 450 to accommodate one end of the telescopic rod 490. In this embodiment, since only a motor is used for driving, the structure is relatively simple, without the complexity of a hydraulic system, resulting in lower operating costs and facilitating handling and transportation.

[0044] See you again Figure 1 , Figure 2 , Figures 4 to 6In practical applications, there are heavy minerals that need to be hoisted in mines, resulting in high torque transmitted by the motor. Therefore, a keyed connection is generally provided between the coupling flange and the motor shaft to improve the torque transmitted between them. Furthermore, due to the interplay between the keyway and the key, the keyways on the coupling flange and the motor shaft need to be aligned during installation. This requires the clamping device 300 to rotate the entire coupling flange together to accommodate the above situation. Therefore, in one embodiment of this application, the clamping device 300 includes a rotating base 310, a pair of clamping arms 320, and an adjusting screw 330. Both clamping arms 320 are slidably mounted in the sliding groove 340 at the outward end of the rotating base 310. The threads on the two ends of the adjusting screw 330 rotate in opposite directions. The rotating seat 310 is rotatably mounted on the hinge seat 210, and the rotating seat 310 and the hinge seat 210 can be locked together. Both ends of the adjusting screw 330 are rotatably mounted on the rotating seat 310 and are respectively connected to the sliding ends of the two clamping arms 320 via screw nuts. A rotating flange 350 is provided on one end of the adjusting screw 330. A clamping block 360 is provided on the outward-facing end of each of the two clamping arms 320, and a V-groove 370 is formed on the facing side of each of the two clamping blocks 360. By rotating the adjusting screw 330, the two clamping arms 320 can be adjusted to slide in opposite directions within the sliding groove 340. This design can accommodate clamping of coupling flanges of different specifications, improving ease of use. The V-groove 370 is designed to accommodate coupling flanges of different thicknesses, ensuring stable clamping. In addition, the clamping block 360 has a perforation in the middle to accommodate the edge of the coupling flange and improve the clamping ability.

[0045] See Figure 5 and Figure 6In the above embodiments, the rotating seat 310 and the hinge seat 210 can be locked using a pin and positioning hole. However, this positioning method cannot achieve locking at any angle, which is not conducive to adjusting the relative angle between the coupling flange and the motor spindle. Therefore, in one embodiment of this application, a rotating cylinder 311 is provided on the rotating seat 310. The rotating cylinder 311 is rotatably installed in the mounting hole 211 of the hinge seat 210. A gear ring 312 is fitted on the rotating cylinder 311, and a servo motor 213 is provided on the hinge seat 210. The servo motor 213 is provided with an adjusting gear 212 that meshes with the gear ring 312. In this embodiment, the servo motor 213 controls the adjustment of the rotation angle, eliminating the hassle of manual adjustment. However, in some embodiments, to reduce overall operating costs, the adjusting gear 212 is mounted on the hinge seat 210 via a rotating shaft, and a handwheel is provided at the outward end of the rotating shaft. This configuration allows for manual adjustment. Furthermore, in the aforementioned manual adjustment design, a ratchet can be provided on the hinge seat 210 to restrict the rotation of the adjustment gear 212 relative to the locking rotation shaft.
