Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem that existing cross-shaped rotary arms can only suspend silicon steel coils and lack a structure for securing them, which leads to the silicon steel coils easily falling off the cross-shaped rotary arms during transport and causing safety accidents, this utility model provides a suspension arm assembly that can secure the silicon steel coils after they are fitted onto the rotary arm, thereby preventing the silicon steel coils from easily falling off the rotary arm and causing safety accidents.

[0020] It should be noted that the suspension arm assembly described in this utility model is used in, but not limited to, RGV transfer vehicles. For ease of explanation, this utility model only uses the application of the suspension arm assembly in an RGV transfer vehicle as an example. The principle of the suspension arm assembly applied to other types of equipment is essentially the same as that applied to an RGV transfer vehicle, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1This is a schematic diagram of the suspension arm assembly in one embodiment of the present invention. The suspension arm assembly 100 includes a support arm 1 and a reinforcing mechanism 2. The reinforcing mechanism 2 includes a locking member 23. The sliding direction of the locking member 23 is set at an angle to the length extension direction of the support arm 1. The locking member 23 can abut against the inner wall of the silicon steel coil 6, which is sleeved along the length extension direction of the support arm 1, when sliding. The support arm 1 is used to support the silicon steel coil 6. The width of the support arm 1 is smaller than the inner diameter of the silicon steel coil 6, so that the silicon steel coil 6 can be sleeved on the support arm 1 along the length extension direction of the support arm 1. The support arm 1 can suspend and transport the silicon steel coil 6. The locking member 23 abuts against the inner wall of the silicon steel coil, which can limit the silicon steel coil 6 and prevent the silicon steel coil 6 from easily falling off the support arm 1 during transportation.

[0022] In one embodiment, please refer to Figure 1 The reinforcement mechanism 1 also includes a sliding member 21 and a linkage member 22. The sliding member 21 is slidably disposed on the support arm 1 along the first direction, and the locking member 23 is slidably disposed on the support arm 1 along the second direction. The second direction is set at an angle to the first direction. The two ends of the linkage member 22 are rotatably connected to the sliding member 21 and the locking member 23.

[0023] In this embodiment, the second direction is preferably perpendicular to the first direction so that the sliding member 21 can adjust the position of the locking member 23 by a large margin when sliding, thereby improving the efficiency of fixing the silicon steel coil 6.

[0024] The linkage 22 is also set at an angle to both the first and second directions. When the sliding member 21 slides along the first direction, it drives the linkage 22 to rotate. The linkage 22 then drives the locking member 23 to slide along the second direction to press against the inner wall of the silicon steel coil 6, thereby fixing the silicon steel coil 6 and preventing it from easily falling off the support arm 1. When it is necessary to unload the silicon steel coil 6, the sliding member 21 can be controlled to slide in the opposite direction, so that the locking member 23 can be driven by the linkage 22 to slide away from the inner wall of the silicon steel coil 6, unlocking the silicon steel coil 6 and allowing it to be unloaded from the support arm.

[0025] In one embodiment, please refer to Figure 1 The reinforcing mechanism 2 also includes a guide member 24 disposed on the support arm 1. The guide member 24 has a groove along the first direction, and the sliding member 21 is slidably disposed in the groove. In this embodiment, the guide member 24 is installed on the support arm 1 by screws, and the sliding member 21 can slide back and forth along the guide member 24, so as to drive the locking member 23 to abut or disengage from the silicon steel coil 6 through the linkage member 22. In this embodiment, by setting the guide member 24 and the sliding member 21 to slide slidably, the sliding member 21 can stably slide back and forth along the first direction. Figure 2The embodiment shown has multiple guide members 24, which are spaced apart along a first direction, and the multiple grooves opened on the multiple guide members 24 are all located on the same straight line, so that the slider 21 can slide simultaneously in the multiple grooves.

[0026] In one embodiment, please refer to Figure 2 The reinforcing mechanism 2 also includes a limiting member 25 disposed on the support arm 1. The limiting member 25 has a limiting surface 251 parallel to the second direction on the side facing the linkage member 22. The linkage member 22 can slide along the limiting surface 251 and drive the locking member 23 to slide when the sliding member 21 slides. In this embodiment, the limiting member 25 is approximately L-shaped and is detachably installed on the support arm 1 by screws. When the sliding member 21 slides, it can drive the linkage member 22 to move. The end of the linkage member 22 near the locking member 23 abuts against the limiting surface 251 and can reciprocate along the limiting surface 251. The limiting surface 251 is used to provide a guiding support surface for the movement of the linkage member 22 so that the linkage member 22 can move stably to drive the locking member 23 to slide.

[0027] In one embodiment, please refer to Figure 1 The reinforcement mechanism 2 also includes a fixing member 26 disposed on the support arm 1. The fixing member 26 has a through guide hole along the second direction. The locking member 23 is slidably inserted into the guide hole and can extend through the guide hole to abut against the inner wall of the silicon steel coil 6. In this embodiment, the fixing member 26 is slidably connected to the locking member 23 through the guide hole, which provides guidance and support for the locking member 23, so that the locking member 23 can stably slide back and forth along the second direction to abut against or disengage from the silicon steel coil 6. The fixing member 26 is disposed on the edge of the support arm 1. When the locking member 23 passes through the guide hole of the fixing member 26, the part of the locking member 23 that extends out can exceed the edge of the support arm 1 and abut against the inner wall of the silicon steel coil 6.

[0028] In one embodiment, please refer to Figure 3 The locking member 23 has a damping surface 231 on its end face away from the linkage member 22. In this embodiment, the damping surface 231 can be a friction surface provided on the end face of the locking member 23 away from the linkage member 22, or it can be a rubber pad provided on the end face of the locking member 23. The end face of the rubber pad away from the locking member 23 is the damping surface 231. In this embodiment, the locking member 23 can abut against the inner wall of the silicon steel coil 6 through the damping surface 231, so as to increase the friction between the locking member 23 and the silicon steel coil 6, so that the silicon steel coil 6 can be stably fixed to the support arm 1.

[0029] In other embodiments, please refer to Figure 1 and Figure 2The end face of the locking member 23 away from the linkage member 22 can also be connected to a limiting rod 27. When the locking member 23 slides away from the linkage member 22, the locking member 23 can drive the limiting rod 27 to abut against the inner wall of the silicon steel coil to fix the silicon steel coil. In this embodiment, the limiting rod 27 abuts against the silicon steel coil, resulting in a large contact area with the silicon steel coil and a more stable fixation of the silicon steel coil.

[0030] In one embodiment, please refer to Figure 3 Two linkage members 22 and two locking members 23 are provided. The two locking members 23 are located on both sides of the sliding member 21. One end of each linkage member 22 is rotatably connected to the sliding member 21, and the other end of each linkage member 22 is rotatably connected to the two locking members 23. In this embodiment, when the sliding member 21 slides, it can simultaneously drive the two linkage members 22 to move. The two linkage members 22 can drive the two locking members 23 to slide towards or away from each other. When the two locking members 23 slide away from each other, they can simultaneously abut against the inner wall of the silicon steel coil 6, so as to limit multiple parts of the inner wall of the silicon steel coil 6, making the silicon steel coil 6 more stable.

[0031] In one embodiment, please refer to Figure 3 The two linkage members 22 and the two locking members 23 located on both sides of the sliding member 21 form a reinforcement unit. The reinforcement mechanism 2 includes multiple reinforcement units, which are distributed at intervals along the first direction. Figure 2 The embodiment shown has two reinforcement units, which are spaced apart. When the sliding member 21 slides, it can simultaneously drive the two reinforcement units to abut against the inner wall of the silicon steel coil 6, which can further enhance the stability of the hoisting of the silicon steel coil 6.

[0032] In one embodiment, please refer to Figure 2 The suspension arm assembly 100 also includes a drive mechanism 3, which includes a drive cylinder 31 and a telescopic rod 32. The telescopic rod 32 connects the drive cylinder 31 and the sliding member 21, and can drive the sliding member 21 to slide back and forth under the drive of the drive cylinder 31. In this embodiment, the movement of the sliding member 21 is accomplished by the drive cylinder 31 driving the telescopic rod 32 to extend and retract. The telescopic rod 32 extends and retracts relatively quickly, resulting in high efficiency in controlling the sliding of the sliding member 21.

[0033] In other embodiments, the drive mechanism includes a drive motor and a lead screw. The lead screw connects the drive motor and the slider 21. The lead screw can rotate under the drive motor to drive the slider 21 to slide back and forth via a thread. In this embodiment, the slider 21 slides back and forth by the drive motor driving the lead screw to rotate, and the lead screw drives the slider 21 to slide via a thread. The threaded drive method can control the sliding of the slider 21 more precisely.

[0034] Please see Figure 4Secondly, this utility model also discloses an RGV transfer vehicle 200, including a vehicle body 4, a turntable 5 and multiple suspension arm assemblies 100 as described above. The support arms 1 of the multiple suspension arm assemblies 100 are connected around the periphery of the turntable 5, and the turntable 5 is rotatably connected to the vehicle body 4.

[0035] In this embodiment, four suspension arm assemblies 100 are connected to the periphery of the turntable 5. These four suspension arm assemblies 100 can simultaneously suspend four silicon steel coils 6 and can individually fix each of the four silicon steel coils 6. The turntable 5 can rotate relative to the vehicle body 4 to adjust the position of the silicon steel coils. The vehicle body 4 can travel along the track to move the silicon steel coils suspended by the suspension arm assemblies to the target position for production.

[0036] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The suspension arm assembly 100 provided by this utility model can be applied to an RGV transfer vehicle. The support arm of the suspension arm assembly 100 can be used to suspend the silicon steel coil 6. After the silicon steel coil 6 is sleeved on the support arm 1, it can drive the sliding member 21 to slide relative to the support arm 1 in a first direction. The sliding member 21 can drive the locking member 23 to slide in a second direction through the linkage member 22, so that the locking member 23 abuts against the inner wall of the silicon steel coil 6 and locks the silicon steel coil 6, so as to prevent the silicon steel coil from falling off the support arm 1 during the transfer of the silicon steel coil 6 by the RGV transfer vehicle and causing a safety accident.
