Description

Technical Field

[0001] This invention belongs to the technical field of leveling devices, specifically a self-balancing three-ring reducer flexible suspension leveling device. Background Technology

[0002] Three-ring reducers, with their high reduction ratio and large output torque, are widely used in heavy-duty transmission scenarios such as metallurgy, mining, and hoisting. They are core components of industrial transmission systems. To ensure their operational stability and prevent excessive shaking and vibration during operation from affecting transmission accuracy and equipment lifespan, a flexible suspension structure is usually installed. This structure can effectively buffer the vibration and impact generated by the reducer's operation, reduce stress damage caused by rigid connections, and reduce operating noise. In addition, before formal installation, the entire set of equipment must be precisely leveled using a special leveling device. By calibrating the equipment's level and installation benchmark, problems such as uneven force and operational deviation caused by installation tilt are avoided. This improves the overall stability of the device from the source, ensuring the long-term efficient, stable, and reliable operation of the three-ring reducer.

[0003] For example, utility model CN215763189U discloses a three-ring reducer with flexible shock absorption, including a base, a three-ring reducer body, an L-shaped connecting plate, an output shaft, a top plate, a top cover, and an input shaft. The three-ring reducer body has L-shaped connecting plates fixedly connected to both sides of its bottom via connecting screws. Fixed columns are connected to both sides of the bottom of each L-shaped connecting plate. Columnar base blocks are installed at both ends of the top of the base via mounting grooves. A slot is provided on the top of each columnar base. A rubber sleeve is fitted around the bottom of each fixed column, and the rubber sleeve is located within the slot. This novel reducer features a flexible shock absorption structure, enabling flexible shock absorption with excellent shock absorption effect. The reducer can easily achieve good dustproof performance while also having excellent heat dissipation, making it suitable for widespread use.

[0004] In the existing technology, the existing flexible damping structure can effectively achieve the damping effect. However, the bottom mounting structure usually does not have a direct leveling structure and is directly installed with the pre-reserved screw on the ground. This can easily affect the normal use of the three-ring reducer if the ground is not level. In addition, the existing adjustment device usually requires manual adjustment, and the adjustment requires rotating to change the bottom length, which results in a long time.

[0005] Therefore, a self-balancing three-ring reducer flexible suspension leveling device is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0008] The suspension plate provides an installation position for the bottom suspension structure. The support plate, together with the counterweight plate, has a certain weight to ensure that the center of gravity is always in the center. The bottom structure can be adjusted by pressing down.

[0011] Preferably, a helical gear is mounted on the outer side of the drive shaft, and the helical gear is rotatably disposed on the inner side of the reversing angle device. A fixed bearing is fixedly mounted on the outer side of the upper end of the rotating column, and the fixed bearing is rotatably disposed on the inner side of the support plate.

[0012] Preferably, a trigger switch is embedded in the bottom of the inner side of the movable column, a ball head groove is opened at the bottom of the movable column, and several sets of welding corner seats are installed on the outer side of the upper end of the limiting cylinder, and the welding corner seats are fixedly installed at the bottom of the support plate.

[0013] Preferably, a linkage self-adjusting component is provided at the bottom of the movable column; The linkage self-adjusting component includes a combined ball head, which is rotatably disposed inside the ball head groove. A connecting column is installed at the bottom of the combined ball head, and four sets of stabilizing supports are welded to the outer side of the lower end of the connecting column.

[0014] Preferably, the bottom of the four sets of stabilizing brackets is equipped with a support plate, and the inner side of the support plate is equipped with a limit frame, and the inner side of the upper end of the limit frame is provided with an adjustment groove.

[0015] Preferably, a bearing ring is fixedly installed on the inner side of the lower end of the limiting frame, and a sliding disk is slidably arranged on the inner side of the bearing ring. A limiting slider is slidably arranged on the inner side of the sliding disk, and a guide cover is assembled on the inner side of the limiting slider. A rotating bracket is rotatably arranged on the inner side of the adjusting slide groove, and an installation groove is opened on the inner side of the rotating bracket.

[0016] Preferably, the inner side of the limiting track is provided with a combined bracket, the bottom of the two sets of combined brackets is provided with two sets of connecting rods, the inner side of the lower end of the four sets of connecting rods is provided with limiting posts, and the outer side of the limiting posts is provided with several sets of counterweight plates. The bottom of the limiting posts is provided with locking screws, and the locking screws are located at the bottom of the counterweight plates.

[0017] Preferably, four sets of shock absorbers are installed at the bottom of the suspension plate, and the shock absorbers are fixedly installed on the top of the support plate. A bearing plate is installed on the top of the suspension plate by bolt assembly, and a three-ring reducer is welded to the top of the bearing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a linkage self-leveling component and a support plate, facilitates adjustment via the underground pressure assistance of the adjusting plate and counterweight. The downward pressure maintains the support plate in a horizontal state. During installation, the counterweight increases the weight of the support plate and ensures the center of gravity is centered. When the ground has a certain angle, the four sets of support structures will first contact the ground, and under the pressure of the support plate's gravity, push the movable column to retract into the limiting cylinder. During the retraction process, the internal rotating column will move slowly. The rotating column located at the highest point of the bottom plane will first contact the bottom trigger switch. When the trigger switch contacts the metal and is energized, the trigger switch will transmit power through the circuit. The signal, through the adjustment of the motor, drives the output-end transmission to rotate 45 degrees. During the rotation, the helical gears and transmission rods combined inside the transmission, transmission sleeve and reversing angle device will drive the helical gears connected to the transmission shaft to rotate synchronously. During the rotation, the bottom rotating column will rotate synchronously along the fixed bearing, and the outer triangular locking plate will rotate and embed into the inner side of the locking groove. By combining these methods, the limit cylinder and the movable column can be restricted. At this time, the four sets of leveling support structures are locked at the same time, and the support plate will always remain in a horizontal state. The self-leveling structure can achieve a fast and automatic leveling effect, effectively reducing the workload of the staff and significantly shortening the time spent on leveling.

[0019] This invention, through the coordinated use of a linkage self-adjusting component and a linkage self-leveling component, facilitates the direct guidance of the adjustment bolt structure's installation position via a downward pressing structure, and locks it in place through a squeezing method. When the device is lowered closer to the ground, the pre-reserved screw will first contact the lower area of ​​the guide cover. During the continuous downward movement, the pressure will push the guide cover and the limiting slider to slide and adjust their position along the inner side of the sliding plate. Simultaneously, the sliding plate can rotate and adjust its position according to the inner side of the bearing ring. During the adjustment process, the rotating bracket can be manually controlled to ensure that the screw structure can pass through the installation groove. As the device continues to move downward, the guide cover will contact the ground and push the sliding plate and the inner structure to move upward along the bearing ring until the support plate contacts the ground. During the upward movement of the sliding plate, contact with the inner wall of the limiting frame can maintain a locked state through friction. The linkage self-adjusting component enables rapid adjustment to adapt to situations where the screw position may shift, facilitating quick positioning and easy installation.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 7 As shown, the present invention provides a flexible suspension leveling device for a self-balancing three-ring reducer, including a suspension plate 100, and a linkage self-leveling component 001 is provided below the suspension plate 100. The linkage self-leveling component 001 includes a support plate 201. A reversing angler 200 is installed inside each of the four corners of the support plate 201. A drive shaft 301 is rotatably installed inside the reversing angler 200. A rotating column 303 is installed at the bottom of the drive shaft 301, and several sets of triangular locking plates 300 are evenly installed on the outer side of the rotating column 303. The linkage self-leveling component 001 also includes a limiting cylinder 401, which is welded to the bottom of each of the four corners of the support plate 201. A movable column 403 is slidably installed on the inner side of the limiting cylinder 401. A sliding frame 404 is installed on the outer side of the upper end of the movable column 403. The top of the sliding frame 404 and the limiting cylinder 401 are elastically connected by a strong spring 405. Several locking grooves 400 are opened on the inner side of the movable column 403, and the triangular locking plates 300 are rotatably installed inside the locking grooves 400.

[0024] The above scheme is adopted as follows: the suspension plate 100 provides an installation position for the bottom suspension structure, the support plate 201 has a certain weight after cooperating with the counterweight plate 700, ensuring that the center of gravity is always located at the center of gravity, and the bottom structure can be squeezed by downward pressure for adjustment, the reversing angler 200 can transmit rotational power, and keep the four sets of structures can share a drive source, thereby ensuring the synchronization of adjustment, the transmission shaft 301 and the reversing angler 200 can transmit kinetic energy through the helical gear 302, and the rotating column 303 can transmit kinetic energy under the action of the transmission shaft 301 to achieve the adjustment effect. The synchronous rotation of the rotating column 303 can drive the outer triangular locking plate 300 to rotate and adjust. The four sets of triangular locking plates 300 on the outside of the rotating column 303 are directional structures when viewed from above, and are kept in the same size as the adjustment channel inside the locking groove 400, ensuring that the rotating column 303 and the triangular locking plate 300 can move up and down along the inside of the locking groove 400 for adjustment.

[0025] like Figures 2 to 4 As shown, a transmission sleeve 205 is installed at the input end of the four sets of reversing anglers 200, and a transmission device 204 is installed at the end of the four sets of transmission sleeves 205 away from the reversing anglers 200.

[0026] An adjusting motor 203 is installed at the input end of the transmission device 204, and the adjusting motor 203 is installed at the bottom of the support plate 201 by bolts. Two sets of limit rails 202 are installed at the bottom of the support plate 201.

[0027] A helical gear 302 is mounted on the outer side of the drive shaft 301, and the helical gear 302 is rotatably mounted on the inner side of the reversing angle device 200. A fixed bearing 304 is fixedly mounted on the outer side of the upper end of the rotating column 303, and the fixed bearing 304 is rotatably mounted on the inner side of the support plate 201.

[0028] A trigger switch 406 is embedded in the bottom of the inner side of the movable column 403. A ball head groove 407 is opened at the bottom of the movable column 403. Several sets of welding corner seats 402 are installed on the outer side of the upper end of the limiting cylinder 401, and the welding corner seats 402 are fixedly installed at the bottom of the support plate 201.

[0029] Using the above scheme: the transmission sleeve 205 connects the reversing angler 200 to the transmission device 204, and also restricts the internal rotating transmission rod structure. The transmission device 204 transmits the driving force of the adjusting motor 203, which provides power support for the device, ensuring that the device can be adjusted and locked normally. The limiting rail 202 provides an installation position for the combined bracket 701, facilitating assembly. The helical gear 302 meshes with the inner structure of the reversing angler 200, and the fixed shaft... The bearing 304 can restrict the inner rotating column 303, effectively ensuring the stability of the rotation of the rotating column 303. The trigger switch 406 can control the adjusting motor 203 through the circuit. The top of the trigger switch 406 can form an electrical circuit after contacting the metal, thereby achieving the effect of signal transmission. The ball head groove 407 can be spliced ​​with the combined ball head 501. After splicing, the stability of the combination can be achieved, and it can be rotated for adjustment. The welded corner seat 402 can increase the stability of the connection between the limiting cylinder 401 and the support plate 201.

[0030] like Figure 5 and Figure 6 As shown, a linkage self-adjusting component 002 is provided at the bottom of the movable column 403; The linkage self-adjusting component 002 includes a combined ball head 501, which is rotatably disposed inside the ball head groove 407. A connecting column 502 is installed at the bottom of the combined ball head 501, and four sets of stabilizing brackets 503 are welded to the outer side of the lower end of the connecting column 502.

[0031] The bottom of the four sets of stabilizing brackets 503 is equipped with a support plate 504, and a limit frame 500 is installed on the inner side of the support plate 504. An adjustment groove 505 is opened on the inner side of the upper end of the limit frame 500.

[0032] A bearing ring 601 is fixedly installed on the inner side of the lower end of the limiting frame 500, and a sliding disk 602 is slidably arranged on the inner side of the bearing ring 601. A limiting slider 603 is slidably arranged on the inner side of the sliding disk 602, and a guide cover 604 is assembled on the inner side of the limiting slider 603. A rotating bracket 605 is rotatably arranged on the inner side of the adjusting slide 505, and an installation groove 600 is opened on the inner side of the rotating bracket 605.

[0033] Using the above scheme: After the combined ball head 501 and the ball head groove 407 are spliced ​​together, they can be rotated and adjusted to adapt to different angle leveling requirements. The connecting column 502 can connect the combined ball head 501 and each set of stabilizing brackets 503. The stabilizing brackets 503 can provide support for the top structure, while ensuring the stability of the connection with the bottom support plate 504. The support plate 504, in contact with the ground, can provide support for the top structure, and its bottom has a certain curvature to accommodate the adjustment of the guide cover 604 on the inside. The limiting frame 500 can provide restriction for the inner structure, allowing for adjustment. The slide groove 505 provides a constraint for the inner rotating bracket 605, assisting in rotation adjustment. The mounting groove 600 allows the screw structure to pass through, facilitating the installation of a nut structure at the top for locking. The guide cover 604 uses its curved surface to cooperate with the reserved screw for adjustment. The limiting slider 603 can slide laterally along the inner side of the sliding plate 602 to adapt to different needs. At the same time, the sliding plate 602 can slide up and down on the inner side of the bearing ring 601. By sliding, the sliding plate 602 can be kept in contact with the inner wall of the limiting frame 500 to lock through friction.

[0034] like Figure 7 As shown, a combination bracket 701 is assembled on the inner side of the limiting track 202. Two sets of connecting rods 702 are installed at the bottom of the two sets of combination brackets 701. Limiting posts 703 are installed on the inner side of the lower end of the four sets of connecting rods 702. Several sets of counterweight plates 700 are sleeved on the outer side of the limiting posts 703. A locking screw 704 is assembled at the bottom of the limiting posts 703, and the locking screw 704 is located at the bottom of the counterweight plate 700.

[0035] Four sets of shock absorbers 101 are installed at the bottom of the suspension plate 100, and the shock absorbers 101 are fixedly installed on the top of the support plate 201. The top of the suspension plate 100 is equipped with a bearing plate 102 by bolt assembly, and a three-ring reducer 103 is welded to the top of the bearing plate 102.

[0036] Using the above solution: the combined bracket 701 can be assembled by sliding laterally on the inner side of the limiting rail 202. The connecting rod 702 can fix the combined bracket 701 to the limiting post 703. The limiting post 703 can provide a restriction for the counterweight plate 700. After connecting the locking screw 704 to the limiting post 703 by thread, the effect of locking and supporting the counterweight plate 700 can be achieved.

[0037] The working principle and usage process of this invention are as follows: During installation, the support plate 201 is adjusted using a suspension method. During installation, ensure that each set of guide covers 604 is roughly aligned with the reserved screw structure. During the downward movement, the screw will push the guide cover 604 to rotate along the inner side of the bearing ring 601. Simultaneously, the limiting slider 603 will slide laterally along the inner side of the sliding plate 602. When the screw passes the upper end of the guide cover 604, roughly control the rotating bracket 605 to rotate along the inner side of the adjusting groove 505 to adjust the position. Finally, the screw will pass through the mounting groove 600. After the guide cover 604 contacts the ground, it will move upward along the inner wall of the bearing ring 601 in conjunction with the sliding plate 602 until the support plate 504 contacts the ground. When the support plate 504 contacts the ground, the downward pressure of the support plate 201, through the stabilizing bracket 503 and the upper combined ball joint 501, will push the limiting cylinder 401 downward along the outer side of the movable column 403. When the device moves downward, its position can be adjusted. The four sets of limit cylinders 401 are adjusted simultaneously until the first set of trigger switches 406 contacts the rotating column 303. After contact, an electrical circuit is formed, thereby controlling the output end of the adjusting motor 203 to rotate rapidly by 45 degrees. During the rotation, the transmission device 204, transmission sleeve 205 and reversing angle device 200 are used to control the rotation adjustment of the transmission shaft 301. During the rotation of the transmission shaft 301, the rotating column 303 will be controlled to rotate along the inner side of the fixed bearing 304. During the rotation of the rotating column 303, each set of triangular locking plates 300 will quickly embed into the inner side of the locking groove 400 to lock. After locking, the suspension structure is removed, and the combined bracket 701 is moved laterally along the inner side of the limit track 202 and pulled out. After being pulled out, the shock absorber 101 and the suspension plate 100 are fixed to the top of the support plate 201. Finally, the three-ring reducer 103 is fixed with bolts.
