Technical Field
[0001] This invention relates to the field of electrical engineering technology, specifically to a ratchet device with a self-lubricating guide spring operating mechanism. Background Technology
[0002] The ratchet mechanism of the spring operating mechanism is the core unidirectional intermittent transmission mechanism of the energy storage transmission unit in the spring operating mechanism of a high-voltage circuit breaker. It is the power conversion hub between the energy storage power source (energy storage motor or manual crank) and the closing spring. It relies on the meshing of the ratchet and pawl to convert the continuous rotation of the motor or the manual reciprocating oscillation into the unidirectional intermittent rotation of the energy storage shaft, gradually stretching / compressing the closing spring to complete energy storage. At the same time, it relies on the unidirectional anti-reverse characteristic to prevent the spring from rebounding and reversing. It is the core component that ensures the stability and reliability of the energy storage process of the operating mechanism.
[0003] Currently, the main lubrication method used for ratchet devices in spring operating mechanisms is manual lubrication, which is the primary mode of on-site maintenance. A specified type of grease is injected using a manual grease gun through the pre-installed grease nipple. While manual lubrication has the advantages of being relatively easy to operate and achieving basic results, it is not the only method.
[0004] However, during maintenance, relevant personnel are required to strictly and timely replenish and add lubricating oil within the specified maintenance cycle. This necessary step not only significantly increases the labor intensity and workload of on-site personnel, but also directly leads to an increase in labor costs, thereby causing the overall cost of manual operation and maintenance to show an upward trend. To address this, we propose a ratchet device with a self-lubricating guide spring operating mechanism. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by adding a guiding mechanism, strictly constrains the rotation or swing path of the crank handle, eliminates radial movement, axial movement and angular wobble when cranking by hand, eliminates motion errors caused by extra degrees of freedom, and greatly improves the stability of the crank handle when operated by the operator.
[0017] This invention, through the design of an automatic lubrication and filling mechanism linked to the crank handle, enables the synchronous and precise addition of lubricating oil to the surface of the large gear in the energy storage unit during manual operation. This innovative structural design allows the lubricating oil addition process to be synchronized with the normal operation of the equipment, eliminating the need for additional manual intervention. This ensures the continuous and efficient supply of lubricating oil while guaranteeing the normal operation of the equipment. This solution fundamentally solves the problems of cumbersome operation, low efficiency, easy omission, and potential aggravated equipment wear due to untimely lubrication caused by the need for regular, manual, and periodic lubrication in traditional maintenance methods.

Detailed Implementation
[0021] 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.
[0022] Example 1 Please see Figure 1- Figure 11 The diagram shows a self-lubricating guide spring-operated ratchet device, comprising: a frame 1, an energy storage system, and a release system; an energy storage shaft 2 and a crank handle 3 are rotatably connected to the frame 1, and a guide mechanism 4 adapted to the crank handle 3 is provided on the frame 1 to provide guidance when the operator turns the crank handle 3 in the forward direction; a support frame 5 is fixed to the frame 1, and a large gear 6 is fixed to the energy storage shaft 2; a filling mechanism 7 adapted to the large gear 6 is provided on the support frame 5, and the filling mechanism 7 quantitatively adds lubricating oil to the teeth of the large gear 6 to maintain the lubrication effect of the energy storage system; and a transmission mechanism 8 is provided on the frame 1 to drive the filling mechanism 7 to rotate intermittently.
[0023] The energy storage system consists of: an energy storage motor, a manual energy storage interface, a reduction transmission component, a one-way ratchet and pawl assembly, and an energy storage shaft 2. The essence of energy storage is to gradually accumulate electrical energy or human work into the elastic potential energy of the closing spring. The core relies on the one-way intermittent transmission characteristics of the ratchet and pawl. The manual crank handle 3 drives the manual swing arm to swing back and forth, and the manual drive pawl drives the ratchet to rotate step by step. The check pawl simultaneously undertakes the reverse stop and energy preservation function.
[0024] It should be noted that the large gear 6 on the energy storage shaft 2 is located at the end of the entire energy storage transmission system and is directly connected to the energy storage shaft 2. The large gear 6 meshes with the small gear at the output end of the energy storage motor to complete the final stage of torque amplification with a large reduction ratio. This converts the high-speed, low-torque rotational motion of the motor into a low-speed, high-torque output of a compressible or stretchable closing spring. It is the torque output terminal of the entire reduction chain. The lubrication mechanism 7 adds lubricating oil to the teeth of the large gear 6, thereby lubricating the transmission components meshing with the large gear 6 and ensuring the normal operation of the entire energy storage system.
[0025] In this technical solution, the guiding mechanism 4 includes: two symmetrically distributed guide grooves 9 are provided on the frame 1, and guide rods 10 are slidably connected in both guide grooves 9; a hinge seat 11 is fixed on the handle 3; a connecting rod 12 is hinged between the hinge seat 11 and one of the guide rods 10; a connecting plate 13 is fixed to one end of both guide rods 10; and the included angle between the guide rods 10 and the connecting plate 13 is 90°.
[0026] The guide rod 10 is fixed with a positioning ring 41 that is slidably connected to the frame 1. The addition of the positioning ring 41 restricts the left and right movement of the guide rod 10, ensuring the stability of the guide rod 10 when it moves. Both ends of the guide groove 9 are set with smooth arc surfaces to avoid the guide rod 10 from getting stuck when it moves to the dead point position.
[0027] It should be noted that the strength that a human can exert at one time is relatively limited. Therefore, in actual operation, it is often necessary to repeatedly turn the crank handle 3 back and forth about 20 to 50 times to complete the reciprocating operation of the energy storage stroke. During this process, the reciprocating motion of the crank handle 3 is converted and transmitted to the guide rod 10 through the transmission mechanism 8 of the connecting rod 12. This causes the guide rod 10 to move along the preset guide groove 9 trajectory, which not only effectively achieves precise guidance of the movement of the crank handle 3, but also significantly improves the stability and control of the operator when turning the crank handle 3, thereby improving the efficiency and safety of the entire energy storage process.
[0028] In this technical solution, the filling mechanism 7 includes: an oil storage cylinder 14 fixed on a support frame 5; an installation cylinder 16 communicating with the interior of the oil storage cylinder 14 is fixed at the bottom of the oil storage cylinder 14; an installation rod 17 is fixed at the bottom of the installation cylinder 16; a channel 18 communicating with the installation cylinder 16 is opened on the installation rod 17; an oil storage hopper 19 is slidably connected inside the channel 18; a limiting plate 47 is fixed inside the oil storage cylinder 14; the limiting plate 47 is located directly above the oil storage hopper 19; the oil storage hopper 19 moves upward to its final position and contacts the limiting plate 47, ensuring that the oil storage hopper 19 always maintains a close sliding state with the installation cylinder 16; and the central axis of the oil storage hopper 19 is aligned with the central axis of the installation cylinder 16. The lines are arranged collinearly, and the oil storage hopper 19 is slidably connected to the inner side of the mounting cylinder 16. A rod 20 that slides through the mounting rod 17 is fixed on the oil storage hopper 19. An oil storage box 22 is fixed on the support frame 5 through a bracket 21. A gear shaft 23 that meshes with the large gear 6 is rotatably connected to the oil storage box 22. An oil delivery pipe 24 is fixed between the oil storage box 22 and the mounting rod 17. The two ends of the oil delivery pipe 24 are respectively connected to the channel 18 and the oil storage box 22. The oil delivery pipe 24 is located obliquely above the gear shaft 23 to ensure that the lubricating oil can be directly added to the gear shaft 23. A permeation hole 25 that is adapted to the oil delivery pipe 24 is opened on the oil storage hopper 19.
[0029] In addition, a pressure booster 15 is provided on the oil reservoir 14. The pressure booster 15 is used to increase the oil pressure of the lubricating oil in the oil reservoir 14. The pressure booster 15 includes: a threaded cover 43 threadedly connected to the oil reservoir 14 through a threaded groove 42; an installation sleeve 44 fixed on the threaded cover 43; a return spring b45 fixed inside the installation sleeve 44; and a pressure plate 46 fixed at the other end of the return spring b45. The pressure plate 46 is slidably connected to the inner side of the oil reservoir 14, and the central axis of the pressure plate 46 is collinear with the central axis of the oil reservoir 14.
[0030] Specifically, the operator rotates the installation sleeve 44 to remove the threaded dust cover, and then injects the required lubricating grease into the oil reservoir 14. After successfully completing the lubricating grease addition step, the operator needs to align the matching pressure plate with the opening on the top of the oil reservoir 14, and then press down evenly to make the threaded structure on the pressure plate 46 tightly engage with the pre-set threaded groove 42 at the opening of the oil reservoir 14, thereby completing the assembly and fixing process of the entire component.
[0031] In this technical solution, the transmission mechanism 8 includes: a rotating rod 27 rotatably connected to the frame 1 via a rotating seat 26; a cam 28 fixed on the rotating rod 27; a transmission ring 29 abutting against the cam 28 fixed on the rod body 20; a return spring a30 sleeved on the rod body 20; the two ends of the return spring a30 being fixed to the transmission ring 29 and the mounting rod 17 respectively; a ratchet body 31 fixed to one end of the rotating rod 27; and a pawl engaging with the ratchet body 31 rotatably connected to the frame 1 via a mounting bracket 32. The body 33 has a toothed plate a34 fixed on one of the guide rods 10. A drive shaft 35 is rotatably connected to the frame 1. A drive gear 36 that meshes with the toothed plate a34 is fixed on the drive shaft 35. A toothed plate b37 that meshes with the drive gear 36 is slidably connected to the frame 1. A groove 38 is provided on the toothed plate b37. A drive claw 39 is slidably connected inside the groove 38. A spring plate 40 is fixed on the drive claw 39. The other end of the spring plate 40 is fixed to the groove 38.
[0032] Specifically, when the toothed plate b37 begins to move towards the pawl body 33, the transmission pawl 39 gradually approaches and makes direct and stable contact with the surface of the pawl body 33. At the moment of contact, the transmission pawl 39 applies a clear pushing force to the pawl body 33. The force is transmitted to the pawl body 33, driving the rotating rod 27 to produce a small-angle rotational motion with a limited amplitude. When the toothed plate b37 moves in the opposite direction, the transmission pawl 39 will contact the pawl body 33 again. After receiving the reaction force from the pawl body 33, the transmission pawl 39 slides compliantly along the preset specific groove 38 trajectory. This sliding process resolves the reverse driving force. At the same time, the pawl body 33, through its own structure and the cooperation with the ratchet body 31, effectively locks the rotation direction, thus ensuring that the shaft in the entire transmission system can only maintain rotation in one direction, realizing a reliable unidirectional transmission function.
[0033] In this scheme, the process of automatically adding lubricating oil to the large gear 6 on the energy storage shaft 2 by turning the crank handle 3 is as follows: By repeatedly operating the crank 3, the operator utilizes the transmission action of the connecting rod 12 to make the guide rod 10 reciprocate linearly along the path planned by the guide groove 9, thereby causing the toothed plate a34 to generate a corresponding synchronous displacement. By utilizing the meshing transmission action between the toothed plate a34 and the transmission gear 36, the power is effectively converted and transmitted, thus guiding the toothed plate b37 to reciprocate along a trajectory completely opposite to that of the toothed plate a34 after being subjected to force. The transmission pawl 39 interacts with the tooth groove of the ratchet body 31 as the toothed plate b37 moves, forming an effective unidirectional transmission mechanism, which causes the rotating rod 27 to achieve unidirectional rotational motion within a limited angle, while simultaneously driving the rotating rod 27 and the cam 28 to rotate synchronously. During the periodic and intermittent rotation of cam 28, the return spring a30 provides a continuous and stable elastic restoring force to ensure that the transmission ring 29 always maintains close contact with the surface of cam 28. When cam 28 gradually rotates to the lowest point of its lift curve, it drives rod 20 and oil reservoir 19 to move synchronously to the lowest point inside mounting cylinder 16. When the permeation hole 25 inside oil reservoir 19 and the oil pipe 24 are accurately aligned, the lubricating oil pre-stored inside oil reservoir 19 will flow smoothly and stably through oil pipe 24 to the surface of gear shaft 23 below under the action of gravity and pressure difference. As the large gear 6 rotates, it drives the gear shaft 23 to rotate. Through the meshing transmission relationship formed between its surface and the large transmission gear 36, the lubricating oil is continuously carried and evenly applied to the working surface of each tooth of the large gear 6, thereby completing the continuous and automatic lubrication process of the entire gear transmission pair, effectively reducing friction loss and ensuring the smooth and long-term operation of the transmission system.
[0034] Example 2: This embodiment supplements Embodiment 1, specifically, as follows: Figure 11 As shown, toothed plates a34 and b37 are staggered and have the same length. The length of toothed plate a34 is greater than the length of guide groove 9. By adjusting the lengths of toothed plates a34 and b37, it is ensured that when guide rod 10 slides in guide groove 9, toothed plates a34 and b37 always maintain meshing with spur gear, preventing disengagement. Several sliding rods 48 are fixed on frame 1. Both toothed plates a34 and b37 are provided with sliding grooves 49 that slide with sliding rods 48. Both sides of the sliding grooves 49 are smooth arc surfaces to prevent the sliding rods 48 from getting stuck in the sliding grooves 49 when the toothed plates a34 and b37 move. Several sliding rods 48 are fixed with limiting rings 50, and the toothed plates a34 and b37 are slidably connected to the limiting rings 50 to prevent the toothed plates a34 and b37 from moving up and down.
