Description

Technical Field

[0001] This utility model relates to the field of speed reducer production and transfer technology, and in particular to a speed reducer transfer device with a protective structure. Background Technology

[0002] In industrial production, speed reducers are key transmission equipment. Their internal gears, bearings and other precision components are extremely sensitive to collisions. Protection and fixation during transportation directly affect the equipment's accuracy and service life.

[0003] Currently available gearbox transfer equipment has significant defects: most traditional transfer tools (such as ordinary pallets and simple supports) lack specialized protective structures. During transfer, multiple gearboxes are often directly stacked or placed side by side without any isolation or buffer design. In short-distance movement within the workshop or long-distance transportation, the gearbox housing is easily scratched and dented, the shaft head is bumped and deformed due to road bumps and collisions with adjacent equipment, and even the internal gear meshing clearance is offset and the bearing is damaged. This not only affects the subsequent assembly accuracy but also requires additional maintenance costs, and in severe cases, it may lead to the direct scrapping of the equipment.

[0004] Although some equipment has simple protective measures, the fixing structure is simple, mostly fixed-size slots or straps, which cannot adapt to the size and weight differences of different models of reducers. When dealing with small reducers, the fixing is too loose and easy to shift. For large reducers, the clamping force is insufficient and it is difficult to stabilize. During transportation, the risk of equipment shaking and tipping is extremely high, which can lead to secondary collision damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a speed reducer transfer device with a protective structure. This solves the technical problems of existing transfer devices lacking protection, being easily damaged by bumps and collisions when stacked, and having simple protective structures that cannot adapt to different speed reducer models, making them prone to displacement and tipping, causing secondary damage. This invention achieves the goal of adapting to speed reducers of different models and sizes, providing a wrap-around fixation to prevent damage from mutual collisions or tipping.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a speed reducer transfer device with a protective structure, including a transfer vehicle, on which multiple transfer boxes are vertically arrayed, and two sets of receiving cavities for accommodating speed reducers are arrayed on the transfer boxes. Electric lifting rods are installed at the four corners on both sides of the transfer boxes, and the free ends of the electric lifting rods are connected to the top transfer boxes. A mounting plate is fixed to the bottom of the transfer boxes, and a rubber air bladder is provided at the bottom of the mounting plate, which is vertically corresponding to the receiving cavity. The rubber air bladder is filled with magnetorheological fluid. An electromagnetic plate corresponding to the rubber air bladder is installed at the bottom of the mounting plate. An extension component suitable for speed reducers is provided on the outside of the receiving cavity. A liquid injection component for replenishing or recovering magnetorheological fluid into the rubber air bladder is provided on the transfer box.

[0007] A further improvement is that a flip baffle is hinged to the outer end of the storage cavity, and rubber pads are provided on the inner walls of both the storage cavity and the flip baffle to prevent damage to the reducer from collisions.

[0008] A further improvement is that the extension component includes a U-shaped groove formed on the outside of the storage cavity, a tension spring fixedly connected to the inner wall of the U-shaped groove, a U-shaped sliding plate slidably disposed in the U-shaped groove fixedly connected to the end of the tension spring, and a flip baffle rotatably connected to the outer end of the U-shaped sliding plate.

[0009] A further improvement is that the liquid injection assembly includes a liquid storage chamber opened in the transfer box, a double-headed water pump installed at the center of the bottom of the transfer box, an infusion tube installed at the liquid outlet of the double-headed water pump, a solenoid valve installed on the infusion tube, and multiple diversion tubes extending into the rubber air bladder installed on the infusion tube.

[0010] A further improvement is that the free end of the topmost electric lifting rod is also equipped with a mounting plate and a rubber airbag, as well as a corresponding liquid injection component.

[0011] A further improvement is that the transfer vehicle is equipped with a storage battery, and a controller is installed on the handle of the transfer vehicle. The storage battery is electrically connected to the controller through wires, and the electric lifting rod, electromagnetic plate, double-headed water pump and solenoid valve are respectively electrically connected to the storage battery through wires.

[0012] By employing the above technical solution, this utility model provides a speed reducer transfer device with a protective structure, which has at least the following beneficial effects: 1. This utility model achieves independent storage of the speed reducers by placing them separately in the storage cavity. Then, the electric lifting rod is activated to pull the rubber airbag down into the storage cavity. The rubber airbag causes the magnetorheological fluid inside it to spread along the outer shell of the speed reducer, thus wrapping the speed reducer. Subsequently, the electromagnetic plate is energized to generate a magnetic field, which causes the magnetorheological fluid in the rubber airbag to change from a low-viscosity Newtonian fluid to a solid-like Bingham fluid, thereby achieving a wrapping and fixing of the speed reducer and preventing it from being damaged by displacement or collision during transportation.

[0013] 2. This utility model, by opening the solenoid valve and starting the dual-head water pump, draws the magnetorheological fluid in the storage chamber into the infusion pipe, and then flows it into the rubber airbag through the diversion pipe to replenish the magnetorheological fluid. This causes the rubber airbag to expand and spread along the surface of the small-volume reducer, thus wrapping and fixing it. When facing a larger-volume reducer, the magnetorheological fluid in the rubber airbag is squeezed and flows back into the storage chamber through the diversion pipe and the infusion pipe, preventing the rubber airbag from being squeezed too much and bursting.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Given the current lack of protection in existing transport equipment, stacked storage can easily lead to damage from bumps and collisions; some equipment with simple protection has a single fixing structure that cannot adapt to different models of speed reducers, making it prone to displacement and tipping, causing secondary damage. This embodiment provides a speed reducer transport device with a protective structure, capable of adapting to speed reducers of different models and sizes, providing a wrapping and securing solution to prevent damage from collisions or tipping. Please refer to... Figures 1-8 The gearbox transfer device with a protective structure includes a transfer vehicle 1. Multiple transfer boxes 2 are vertically arrayed on the transfer vehicle 1. The transfer boxes 2 have two sets of receiving cavities 3 arranged in an array to accommodate the gearboxes. Electric lifting rods 4 are installed at the four corners on both sides of the transfer boxes 2, and the free ends of the electric lifting rods 4 are connected to the top of the transfer boxes 2. A mounting plate 5 is fixed to the bottom of the transfer boxes 2. A rubber air bladder 6 is set at the bottom of the mounting plate 5, which is perpendicular to the receiving cavity 3 and is filled with magnetorheological fluid. An electromagnetic plate 7 corresponding to the rubber air bladder 6 is installed at the bottom of the mounting plate 5. An extension component 8 suitable for larger gearboxes is set on the outside of the receiving cavity 3. A liquid injection component 9 is set on the transfer box 2 to replenish or recover the magnetorheological fluid into the rubber air bladder 6.

[0019] A flip-up baffle 31 is hinged to the outer end of the storage cavity 3. Both the storage cavity 3 and the inner wall of the flip-up baffle 31 are equipped with rubber pads 32 to prevent damage from collisions with the reducers. Opening the flip-up baffle 31 allows for independent storage of the reducers within the storage cavity 3, preventing damage from collisions during transport. The rubber pads 32 inside the storage cavity 3 further prevent damage from collisions with the box walls. The flip-up baffle 31 is then reset and secured with latches to prevent the reducers from slipping out of the storage cavity 3. Finally, the electric lifting rod 4 is activated. Pull the upper transfer box 2 down until the rubber airbag 6 on the bottom mounting plate 5 of the upper transfer box 2 is pressed into the storage cavity 3. The rubber airbag 6 is subjected to downward pressure, which causes the magnetorheological fluid inside it to spread along the reducer housing and wrap the reducer. Then, the controller 12 controls the battery 11 to energize the electromagnetic plate 7, thereby generating a magnetic field. This causes the magnetorheological fluid in the rubber airbag 6 to change from a low-viscosity Newtonian fluid to a solid-like Bingham fluid, thereby achieving a wrapping fixation of the reducer and preventing it from being damaged by displacement or collision during transportation, thus better protecting the reducer.

[0020] Since the storage cavity 3 has limited space, it may not be able to accommodate a large reducer. Therefore, the extension component 8 includes a U-shaped groove 81 opened on the outside of the storage cavity 3. A tension spring 82 is fixedly connected to the inner wall of the U-shaped groove 81. A U-shaped slide plate 83 that slides in the U-shaped groove 81 is fixedly connected to the end of the tension spring 82. A flip baffle 31 is rotatably connected to the outer end of the U-shaped slide plate 83. When encountering a large reducer, the flip baffle 31 is pulled, which causes the U-shaped slide plate 83 to slide out of the U-shaped groove 81 and stretches the tension spring 82 until the flip baffle 31 moves to the outside of the reducer, thereby expanding the storage space of the storage cavity 3 and improving the versatility of the device.

[0021] Specifically, the free end of the top electric lifting rod 4 is also equipped with a mounting plate 5 and a rubber airbag 6, as well as a corresponding liquid injection component 9. Since the top of the top transfer box 2 is open, a set of mounting plates 5 and rubber airbags 6 are added to the free end of the electric lifting rod 4 on the top transfer box 2, and a corresponding liquid injection component 9 is provided to achieve the wrapping and fixing of the reducer inside the top transfer box 2.

[0022] Specifically, a storage battery 11 is installed on the transfer vehicle 1, and a controller 12 is installed on the handle of the transfer vehicle 1. The storage battery 11 is electrically connected to the controller 12 through wires. The electric lifting rod 4, the electromagnetic plate 7, the double-headed water pump 92 and the solenoid valve 94 are electrically connected to the storage battery 11 through wires. The storage battery 11 supplies power to the electrical equipment in the device, and the controller 12 controls the normal operation of the device.

[0023] Example 2 Because the amount of magnetorheological fluid in the rubber airbag 6 may be excessive when dealing with a large-volume speed reducer, or insufficient when dealing with a small-volume speed reducer, thus failing to adequately encapsulate the speed reducer, therefore, based on Embodiment 1, as follows... Figures 1-8 As shown, the liquid injection assembly 9 includes a liquid storage chamber 91 located within the transfer box 2. A dual-head water pump 92 is installed at the center of the bottom of the transfer box 2. An infusion pipe 93 is installed at the outlet of the dual-head water pump 92. A solenoid valve 94 is installed on the infusion pipe 93. Multiple diversion pipes 95 extending into the rubber airbag 6 are installed on the infusion pipe 93. When the size of the stored reducer is small, the solenoid valve 94 is opened and the dual-head water pump 92 is started to pump the magnetorheological fluid in the liquid storage chamber 91 into the infusion pipe 93. The fluid then flows into the rubber airbag 6 through the diversion pipes 95 to replenish the magnetorheological fluid, causing the rubber airbag 6 to expand and spread along the surface of the small-volume reducer to cover and fix it. When facing a larger-volume reducer, the magnetorheological fluid in the rubber airbag 6 is squeezed and flows back into the liquid storage chamber 91 through the diversion pipes 95 and the infusion pipes 93, preventing the rubber airbag 6 from being squeezed too much and bursting.
