Description

Technical Field

[0001] This utility model relates to the technical field of bases for movable speed reducers, and in particular to a base for a movable speed reducer. Background Technology

[0002] Speed ​​reducers are core components of industrial transmission systems, widely used in metallurgy, mining, chemical, and logistics transportation. Their core function is to reduce the output speed of motors and increase torque, thereby ensuring that various production equipment can operate stably at a preset speed. In actual production operations, speed reducers often need to be moved due to the needs of production line layout adjustments, daily equipment maintenance and repair, and alternating operations at multiple workstations.

[0003] Currently, most gearbox bases in the industry adopt a design that directly contacts the ground. On the one hand, due to the large mass of the gearbox itself, its weight can effectively offset the vibration generated by the equipment operation during operation, preventing the base from shifting and ensuring operational stability. On the other hand, precisely because of the large mass of the gearbox itself, the difficulty of moving it increases significantly when it needs to be moved. Usually, it requires multiple people to work together to move it or to use hoisting equipment to complete the moving operation. Not only is the operation process cumbersome and consumes a lot of manpower and time, but there are also safety hazards such as collisions and falls during the handling and hoisting process, which can damage the safety of operators and the integrity of the equipment. Therefore, we have proposed a movable gearbox base. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a base for a movable speed reducer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a base for a movable speed reducer, comprising a speed reducer, a base fixedly installed at the bottom of the speed reducer, extension rods extending from both ends of the base being rotatably installed, rotating seats being sleeved at the ends of the two extension rods, universal wheels being rotatably installed on the sides of the rotating seats, a fixed seat being fixedly installed at the top of the speed reducer, a synchronous shaft being provided on the fixed seat, a ring sleeve being slidably sleeved on the output shaft of the speed reducer, and a movable component being provided between the two rotating seats.

[0006] Preferably, the outer wall of the ring is fitted with a drive bevel gear, and a fixing screw is threadedly connected to the lower part of the outer wall of the ring corresponding to the drive bevel gear. The fixing screw is threadedly connected to the outer wall of the output shaft through the ring.

[0007] Preferably, the two ends of the synchronous shaft extend rotatably beyond the two ends of the fixed seat, one end of the synchronous shaft is fitted with a driven bevel gear that meshes with the driving bevel gear, and the other end of the synchronous shaft is fitted with an adjusting gear.

[0008] Preferably, a rack extending from the bottom of the base is slidably mounted on the top of the base, and the back of the rack meshes with an adjusting gear.

[0009] Preferably, the movable component includes a fixed iron plate, a rotating shaft, a convex shaft, a linkage rod, a round hole, and a spring. A pair of fixed iron plates are fixedly installed on the top of each of the four rotating seats. A rotating shaft is rotatably installed between the pair of fixed iron plates. A convex shaft is sleeved on the outer wall of the rotating shaft. A linkage rod is slidably installed between two convex shafts on the same side. A round hole is opened at both ends of the linkage rod. The convex shaft slides into the round hole. A spring is fixed on the inner wall of the round hole. One end of the spring is fixed to the inner wall of the round hole, and the other end of the spring is fixed to the other end of the convex shaft.

[0010] Preferably, a pull rod is fixedly connected between the two linkage rods at the bottom of the corresponding base, and the bottom of the rack is sleeved on the outer wall of the pull rod.

[0011] The beneficial effects of this utility model are:

[0012] In use, traditional reducer bases are heavy and require multiple people to move or hoisting equipment, which is cumbersome and consumes a lot of manpower and time. However, when the reducer needs to be moved, the device starts the reducer and uses its output shaft to drive the movable components, so that the casters contact the ground and lift the base. At this time, only the reducer needs to be pushed, and the position can be easily moved by the casters. There is no need for multiple people to move or hoisting equipment, which greatly reduces the difficulty of moving and saves manpower and time costs.

[0013] In actual production, there is a need for alternating operations at multiple workstations, requiring the speed reducer to move frequently. This device enables the speed reducer to move quickly and conveniently between different workstations without the need for complex disassembly and reinstallation, effectively improving production efficiency and meeting the flexibility requirements of alternating operations at multiple workstations.

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

[0023] like Figures 1-5 As shown, a movable speed reducer base is disclosed, comprising a speed reducer 1, a base 2 fixedly mounted on the bottom of the speed reducer 1, extension rods 3 extending from both ends of the base 2 rotatably mounted, and rotating seats 4 sleeved at the ends of the two extension rods 3. Universal wheels 5 are rotatably mounted on the sides of the rotating seats 4. A fixed base 12 is fixedly mounted on the top of the speed reducer 1, and a synchronous shaft 13 is provided on the fixed base 12. A ring sleeve 18 is slidably sleeved on the output shaft of the speed reducer 1. A movable component is provided between the two rotating seats 4. The rotating seats 4 are rotatably mounted on the ends of the extension rods 3, and the universal wheels 5 are rotatably mounted on the sides of the rotating seats 4. This allows the speed reducer 1 to be moved when necessary, through transmission operation, the rotating seats 4 can drive the universal wheels 5 to rotate until they contact the ground, thus raising the base 2. The multi-directional rotation characteristic of the universal wheels 5 allows the speed reducer 1 to move freely and flexibly in all directions without the need for large hoisting equipment or multiple people to move it, greatly reducing the difficulty of movement and labor costs, improving the efficiency of equipment layout adjustment on the production site, and quickly adapting to the needs of different production workstations.

[0024] The outer wall of the ring 18 is fitted with a drive bevel gear 19. A fixing screw 20 is threadedly connected to the lower part of the outer wall of the ring 18 corresponding to the drive bevel gear 19. The fixing screw 20 is threadedly connected to the outer wall of the output shaft through the ring 18. In order to meet the connection requirements of the output shaft of the reducer 1 with other objects, the base is designed with a detachable ring 18 structure: when it is necessary to connect external parts, simply turn the fixing screw 20 to remove it from the 18, and the ring 18 can be removed from the output shaft without disassembling other parts of the base. The operation is simple and avoids the connection difficulties caused by the output shaft being blocked or fixed in the traditional base. It improves the adaptability of the reducer to different external equipment, adapts to different transmission requirements in multi-station alternating operation, and expands the application scenarios of the equipment.

[0025] The two ends of the synchronous shaft 13 extend rotatably beyond the two ends of the fixed seat 12. One end of the synchronous shaft 13 is fitted with a driven bevel gear 14 that meshes with the driving bevel gear 19, and the other end of the synchronous shaft 13 is fitted with an adjusting gear 15.

[0026] A rack 16 extending from the bottom of the base 2 is slidably mounted on the top of the base 2, and the back of the rack 16 meshes with the adjusting gear 15.

[0027] The movable components include a fixed iron plate 6, a rotating shaft 7, a convex shaft 8, a linkage rod 9, a round hole 10, and a spring 11. A pair of fixed iron plates 6 are fixedly installed on the top of each of the four rotating seats 4. A rotating shaft 7 is rotatably installed between the pair of fixed iron plates 6. A convex shaft 8 is sleeved on the outer wall of the rotating shaft 7. A linkage rod 9 is slidably installed between two convex shafts 8 on the same side. A round hole 10 is opened at both ends of the linkage rod 9. The convex shaft 8 slides into the round hole 10. A spring 11 is fixed on the inner wall of the round hole 10. One end of the spring 11 is fixed to the inner wall of the round hole 10, and the other end of the spring 11 is fixed to the other end of the convex shaft 8.

[0028] A pull rod 17 is fixedly connected between the two linkage rods 9 and the bottom of the base 2, and the bottom of the rack 16 is sleeved on the outer wall of the pull rod 17.

[0029] Working principle: When the reducer 1 needs to be moved, the reducer 1 is started. The output shaft of the reducer 1 drives the driving bevel gear 19 on the ring sleeve 18 to rotate, causing the driven bevel gear 14 meshing with it to drive the synchronous shaft 13 to rotate on the fixed seat 12. As the synchronous shaft 13 rotates, the adjusting gear 15 begins to pull the rack 16 meshing with the adjusting gear 15 to slide downward on the base 2. The pull rod 17 synchronously drives the two linkage rods 9 to descend synchronously on both sides of the base 2. As the linkage rods 9 gradually descend, the rotating seat 4 rotates at the end of the extension rod 3, while the cam shaft 8 gradually slides inward into the round hole 10 on the linkage rod 9. At the same time, the cam shaft 8 is connected to the two fixed seats through the rotating shaft 7. The fixed iron plate 6 rotates between the two, and the casters 5 gradually contact the ground during the rotation, raising the base 2 on the ground. When the rotating seat 4 rotates 90 degrees, the reducer 1 is turned off. The reducer 1 can be moved by having the four casters 5 contact the ground at the same time. When the reducer 1 needs to be supported after the movement is completed, the reducer 1 is started to reverse the output shaft of the reducer 1, so that the rotating seat 4 rotates to the initial position. The bottom of the base 2 contacts the ground to support the reducer 1. When it is necessary to connect the output shaft of the reducer 1 to other objects, the fixing screw 20 on the ring 18 is rotated to remove the fixing screw 20 from the ring 18, thereby removing the ring 18 from the output shaft.
