Description

Technical Field

[0001] This application relates to the technical field of speed reducer structures, and in particular to a structure for a support base for a speed reducer. Background Technology

[0002] Large and medium-sized horizontal motors are commonly used in the maintenance or installation of large equipment, such as blowers and coal mills. When these large equipment require maintenance or installation, it is usually necessary to check and adjust the clearances of various internal parts by turning the motor. However, traditionally, when adjusting the clearances between internal components during the maintenance of such large equipment, the clearances can only be checked statically due to the weight of the equipment. It is difficult to grasp the clearance situation in dynamic conditions, which poses a certain risk to the actual operation of the equipment. Therefore, when maintaining and inspecting such large equipment, a speed reducer is usually used in conjunction with the turning motor. The speed reducer reduces the operating speed of the blower and coal mill during operation, thereby enabling maintenance.

[0003] However, because the speed reducer is also quite heavy, and its overall height is insufficient to reach the connection height with the motor, it needs to be raised to that height. Raising the speed reducer increases its center of gravity, making it prone to swaying or even falling when used at specific angles, potentially injuring workers and compromising their safety. Summary of the Invention

[0004] The purpose of this application is to provide a structure for a support base for a speed reducer, in order to solve the problem that the overall center of gravity of the speed reducer is high after it is raised, which can easily cause the overall shaking or even falling accident when the speed reducer needs to be used at a specific angle.

[0005] The technical solution for the support base of a speed reducer provided in this application is as follows: A structure for a support base for a speed reducer includes a base, a plurality of rocker arms rotatably mounted on the base, each rocker arm having a lifting mechanism, a support seat for supporting the speed reducer rotatably mounted on the base, two shock-absorbing components oppositely mounted on the base, the support seat located between the two shock-absorbing components, an elastic component for resetting the shock-absorbing components being disposed between the shock-absorbing components and the base, and a balancing component slidably mounted on the base, a push rod component for sliding the balancing component in the opposite direction to the rotation direction of the support seat being disposed between the shock-absorbing components and the balancing component.

[0006] By adopting the above technical solution, when large equipment needs to be inspected by turning it over, the reducer is installed on the support base, the base is moved to the motor position, and the installation position of the base is adjusted by rotating the rocker arm according to the actual flatness of the ground. Then, the base is raised by the lifting mechanism so that the reducer can be connected to the motor. The shock absorption component acts on the base. When the reducer needs to be adjusted in angle, the center of gravity of the base tilts due to the rotation of the support base to one side. The shock absorption component drives the balance component to slide in the opposite direction of the rotation of the support base through the push rod component, so that the center of gravity of the base is restored and the overall balance is maintained. This effectively reduces the risk of falling due to swaying and ensures the safety of workers.

[0007] Meanwhile, during operation, the speed reducer will vibrate and oscillate to a certain extent. The combination of the shock absorption assembly, push rod assembly and balance assembly can also play a certain role in shock absorption.

[0008] Optionally, the shock absorption assembly includes a shock absorption column disposed on the base, a side shock absorption plate disposed opposite to the shock absorption column, and a bottom shock absorption plate, wherein the side shock absorption plate abuts against the side of the support base, and the bottom shock absorption plate abuts against the bottom of the support base.

[0009] By adopting the above technical solution, two side damping plates abut against opposite sides of the support base, and two bottom damping plates abut against the bottom of the support base. When the support base tilts to one side or vibrates, the side and bottom damping plates will undergo elastic tilting deformation, while simultaneously maintaining an elastic restoring tendency, thus providing elastic support and driving the support base to return to its original position. At the same time, the side and bottom damping plates can support the sides and bottom of the support base, improving stability and providing a certain degree of vibration damping.

[0010] Optionally, the elastic component includes a first elastic element, a second elastic element, and a connecting rod. The connecting rod passes through the side damping plate and the bottom damping plate. The first elastic element connects the side damping plate and the push rod assembly, and the second elastic element connects the bottom damping plate and the base.

[0011] By adopting the above technical solution, the side damping plate and the bottom damping plate located on the same side of the support are connected by a connecting rod to improve the structural strength of both. The first elastic element provides elastic support to the side damping plate and also helps the side damping plate to elastically return to its original position. The second elastic element provides elastic support to the bottom damping plate and also helps the bottom damping plate to elastically return to its original position.

[0012] Optionally, the balancing assembly includes a balancing plate slidably disposed on the base, counterweights disposed opposite to both ends of the balancing plate, and the push rod assembly disposed between the balancing plate and the side damping plate.

[0013] By adopting the above technical solution, when the support seat rotates to one side, the support seat will drive the side damping plate to tilt and deform. At this time, the side damping plate will drive the balance plate to slide in the opposite direction of the rotation direction of the support seat through the push rod assembly, so that the center of gravity of the base is restored and the overall balance is maintained.

[0014] Optionally, the push rod assembly includes two push rods, a transmission component, and a push plate slidably disposed on the base. One end of each push rod is disposed on the corresponding side damping plate, and the other end is disposed on the push plate. The push plate drives the balance plate to slide through the transmission component.

[0015] By adopting the above technical solution, during the tilting deformation of the side damping plate, the push rod is driven to move, and the push rod drives the push plate to slide and drives the balance plate to slide through the transmission component.

[0016] Optionally, the transmission component includes a transmission gear rotatably mounted on the base, a driving rack mounted on the push plate and meshing with the transmission gear, and a driven rack mounted on the balance plate and meshing with the transmission gear.

[0017] By adopting the above technical solution, when the plate slides, the active rack drives the transmission gear to rotate, and the transmission gear drives the driven rack to move, thereby driving the balance plate to slide.

[0018] Optionally, the base is provided with a drive shaft, the drive gear is rotatably mounted on the drive shaft, and the base is provided with a reset member for driving the drive gear to reset and rotate.

[0019] By adopting the above technical solution, when the transmission gear rotates and drives the driven rack to slide, the reset component undergoes elastic deformation under force. When the side damping plate elastically resets, the reset component also elastically resets due to reduced force, allowing the driven rack and driving rack to reset in a timely manner. This repeated action effectively buffers and dampens vibrations generated during the reducer's operation, reducing the likelihood of damage caused by excessive vibration.

[0020] Optionally, the rocker arm is rotatably connected to the base via a rotating component. The base is equipped with a hydraulic assembly and an oil tank. The hydraulic assembly controls the lifting mechanism's raising and lowering via hydraulic oil from the oil tank.

[0021] By adopting the above technical solution, the hydraulic components control the flow of hydraulic oil in the tank to and from the lifting mechanism via pipelines to achieve the lifting and lowering of the base. The rocker arm and the base are rotatably connected by a rotating component and fixed at the required angle.

[0022] Optionally, the base is equipped with a horizontal level and a vertical level, and the bottom of the base is equipped with casters.

[0023] By adopting the above technical solutions, the horizontal and vertical level indicators can play a role in balancing and guiding the rocker arm and lifting mechanism. The casters facilitate the operator's control over the overall sliding of the base.

[0024] Optionally, the base is provided with a rotating seat, the support seat is rotatably mounted on the rotating seat, and the rotating seat is provided with a locking element to restrict the rotation of the support seat.

[0025] By adopting the above technical solution, the angle adjustment and fixation of the support base can be achieved.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When large equipment needs to be inspected by turning it over, install the reducer on the support base, move the base to the motor position, and adjust the installation position of the base by rotating the rocker arm according to the actual flatness of the ground. Then, raise the base using the lifting mechanism so that the reducer can be connected to the motor. The shock absorption component acts on the base. When the reducer needs to be adjusted in angle, the center of gravity of the base tilts due to the rotation of the support base to one side. The shock absorption component drives the balance component to slide in the opposite direction of the rotation of the support base through the push rod component, so that the center of gravity of the base is restored and the overall balance is maintained. This effectively reduces the risk of falling due to swaying and ensures the safety of workers. 2. When the support seat rotates to one side, the support seat will cause the side damping plate to tilt and deform. At this time, the side damping plate will drive the balance plate through the push rod assembly to slide in the opposite direction of the rotation of the support seat, so that the center of gravity of the base is restored and the overall balance is maintained. 3. When the transmission gear rotates and drives the driven rack to slide, the reset component undergoes elastic deformation under force. When the side damping plate elastically resets, the reset component also elastically resets due to reduced force, allowing the driven and driving racks to reset in a timely manner. This reciprocating action effectively buffers and dampens vibrations generated during the operation of the reducer, reducing the risk of damage caused by excessive vibration.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0030] This application discloses a structure for a support base for a speed reducer.

[0031] Reference Figure 1 , Figure 2 A structure for a speed reducer support base 1 includes a base 1 and multiple rocker arms 2 rotatably connected around the base 1 at intervals. Each rocker arm 2 has a lifting mechanism 21 at its end furthest from the base 1.

One end of the torsion spring is fixedly connected to the transmission gear 63, and the other end is fixedly connected to the base 1.

[0036] Reference Figure 1 The rocker arm 2 and the base 1 are rotatably connected via a rotating component 18. The rotating component 18 includes a rotating shaft rotatably connected to the base 1, a worm gear, and a motor. The worm gear is sleeved on the rotating shaft. The motor drives the worm gear to rotate the worm gear and the rotating shaft. When the motor stops, the rotating shaft stops rotating. One end of the rocker arm 2 is fixedly connected to the rotating shaft. The base 1 is equipped with a hydraulic assembly and an oil tank 14. The lifting mechanism 21 is a hydraulic cylinder fixedly connected to the end of the rocker arm 2. The hydraulic assembly includes an oil inlet pipe and an oil return pipe connected to the hydraulic cylinder. The oil inlet pipe and the oil return pipe are also connected to the oil tank 14. The hydraulic assembly also includes switching valves installed on the oil inlet pipe and the oil return pipe.

[0037] Reference Figure 4 A rotating seat 16 is fixedly connected to the upper side of the base 1, and a support seat 11 is rotatably connected to the rotating seat 16. The rotating seat 16 is provided with a locking member 17 to restrict the rotation of the support seat 11. The locking member 17 consists of a connecting shaft fixedly connected to the support seat 11 and a clamping cylinder provided on the rotating seat 16. The connecting shaft is rotatably connected to the rotating seat 16, and the clamping cylinder is provided with two clamping parts. The two clamping parts clamp the connecting shaft to achieve fixation.

[0038] Reference Figure 1The base 1 is equipped with a horizontal level 7 and a vertical level 8, and the bottom of the base 1 is equipped with casters 15. The base 1 is equipped with a controller, which is connected to the switch valves, hydraulic cylinders, motors, horizontal level 7, vertical level 8, and clamping cylinders on the oil inlet and return pipes. The controller controls the motor, hydraulic cylinders, and switch valves through data feedback from the horizontal level 7 and vertical level 8.

[0039] The implementation principle of the support base structure for a speed reducer in this application embodiment is as follows: When large equipment needs to be inspected by turning it over, the reducer is installed on the support base 11, and the base 1 is moved to the motor position. Depending on the flatness of the ground, the installation position of the base 1 is adjusted by rotating the rocker arm 2. Then, the base 1 is raised using the lifting mechanism 21, allowing the reducer to connect to the motor. The shock-absorbing component 3 acts on the base 1. When the reducer needs angle adjustment, the center of gravity of the base 1 tilts due to the rotation of the support base 11. The shock-absorbing component 3, through the push rod assembly 6, drives the balance component 5 to slide in the opposite direction of the rotation of the support base 11, restoring the center of gravity of the base 1 and maintaining overall balance. This effectively reduces the risk of falls and ensures the safety of workers.

[0040] Two side damping plates 32 abut against opposite sides of the support base 11, and two bottom damping plates 33 abut against the bottom of the support base 11. When the support base 11 tilts to one side or vibrates, the side damping plates 32 and bottom damping plates 33 will undergo elastic tilting deformation, while simultaneously maintaining an elastic restoring tendency, thus providing elastic support for the support base 11 and driving it to return to its original position. At the same time, the side damping plates 32 and bottom damping plates 33 can support the sides and bottom of the support base 11, improving stability.

[0041] When the support base 11 rotates to one side, it causes the side damping plate 32 to tilt and deform. At this time, the side damping plate 32 drives the balance plate 51 through the push rod assembly 6 to slide in the opposite direction of the rotation of the support base 11, so that the center of gravity of the base 1 is restored and the overall balance is maintained. During the tilting deformation of the side damping plate 32, it drives the push rod 61 to move. The push rod 61 drives the push plate 62 to slide and drives the balance plate 51 to slide through the transmission component. When the push plate 62 slides, the driving rack 64 drives the transmission gear 63 to rotate. The transmission gear 63 drives the driven rack 65 to move, so as to drive the balance plate 51 to slide. When the transmission gear 63 rotates and drives the driven rack 65 to slide, the reset member 13 is subjected to force and undergoes elastic deformation. When the side damping plate 32 elastically resets, the force on the reset member 13 is reduced and it can also elastically reset, so that the driven rack 65 and the driving rack 64 can be reset in time. This repeated process effectively buffers and dampens vibrations generated during the operation of the speed reducer, reducing the risk of damage caused by excessive vibration.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
