Technical Field

[0001] This utility model relates to the technical field of safety protection for warehouse vehicles, specifically a novel stand-and-drive type protective arm for warehouse vehicles. Background Technology

[0002] Warehouse truck safety arms are typically installed on both sides of the mast of forklifts and other warehouse vehicles. They are crucial safety devices during operation and travel, used to physically isolate the operating area and reduce the risks to personnel from collisions with the mast, loads, falling objects, and obstacles in front. To balance safety and efficient logistics, the arrangement and dimensional control of the safety arms or support structures are particularly critical.

[0003] According to Chinese Patent No. CN221986471U, a warehouse handling vehicle includes a main body, a handrail fixed to the top of the main body, a motor fixed to the main body, a rotating rod fixed to the output end of the motor, an unloading winding wheel and an loading winding wheel fixed to the rotating rod, an unloading wire rope fixed to the unloading winding wheel, a sliding plate fixed to one end of the unloading wire rope, a loading wire rope fixed to the loading winding wheel, one end of the loading wire rope fixed to one end of the sliding plate, and a sliding rod slidably installed in the slide rail.

[0004] The above solution still has the following drawbacks: during transportation and loading / unloading, the fixed handrails are difficult to fold or fold down, which can easily increase the space occupied by the overall vehicle outline. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of protective arm for stand-on warehouse vehicles, in order to solve the problem that fixed handrails are difficult to fold or fold down during transportation and loading / unloading, which easily increases the space occupied by the overall vehicle outline.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a novel stand-on warehouse vehicle protective arm, comprising two support plates, both of which are fixed to the top surface of a base plate. A protective arm body is rotatably mounted above the base plate. A fixed bracket is detachably mounted on the top surface of the support plates. Two upper limit plates are fixed to the surface of the protective arm body, and a lower limit plate is fixed to the surface of the protective arm body. Two fixed plates are fixed to the top surface of the base plate. An upper limit groove is formed on the top surface of the fixed plate, and a lower limit groove is formed on one side of the fixed plate.

[0007] Preferably, the top surface of the support plate is fixed with two threaded posts, the fixed bracket is slidably inserted with the threaded posts, and the threaded posts are threaded with nuts through the top surface of the fixed bracket.

[0008] Preferably, two positioning plates are fixed on the top surface of the base plate, a positioning pin is inserted between the two positioning plates, and a movable limiting plate is inserted on the positioning pin.

[0009] Preferably, a movable limiting connecting plate is provided on one side of the movable limiting plate, and a plurality of fixing holes are provided on one side of the movable limiting connecting plate. Bolts are inserted into the fixing holes, and one end of the bolts passes through the fixing holes and is threaded into the interior of the movable limiting plate.

[0010] Preferably, the bottom surface of the base plate is fixed with two support feet, and a reinforcing plate is provided below the base plate, with one side of the reinforcing plate fixed to one side of the support feet.

[0011] Preferably, handles are fixed at both ends of the protective arm body.

[0012] Compared with existing technologies, a novel stand-on warehouse truck protective arm that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] 1. By setting the protective arm body to be able to flip relative to the support plate and fixed bracket, and using the cooperation of the upper limit plate and the upper limit groove, and the lower limit plate and the lower limit groove to achieve the flip angle limit, the protective arm body can be stably positioned under working conditions such as flipping up to the position, horizontal protection, and flipping down to the bottom. Thus, it can be flipped up and folded in the transportation state to reduce the space occupied by the vehicle's outline, and maintain the necessary lateral protection in the working state.

[0014] Second, by setting a positioning plate and positioning pin on the base plate, and setting the movable limit connecting plate as a detachable structure with multiple fixing holes, the relative assembly position of the movable limit connecting plate and the movable limit plate can be adjusted in stages, thereby enabling the installation height of the base plate and the protective arm body to be adapted, improving the versatility and on-site adaptability for operators of different heights or body types.

[0015] Third, by setting handles at both ends of the protective arm body, the operator's force application position is far away from the clamping gap between the protective arm body and the support plate and fixed bracket, thereby reducing the risk of pinching injury. The cooperation between the support foot and the reinforcing plate forms a torque transmission and distribution path, so that the load generated during the flipping process is transmitted to the vehicle body structure more evenly, thereby reducing the risk of cracking or loosening of the bottom plate or support foot and improving the long-term reliability of the protective arm assembly.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, a novel stand-on warehouse vehicle protective arm includes two support plates 1, both of which are fixed to the top surface of a base plate 10. A protective arm body 3 is rotatably mounted above the base plate 10. A fixed bracket 2 is detachably mounted on the top surface of the support plate 1. Two upper limit plates 4 and a lower limit plate 5 are fixed to the surface of the protective arm body 3. Two fixed plates 6 are fixed to the top surface of the base plate 10. An upper limit groove 7 is opened on the top surface of the fixed plate 6, and a lower limit groove 8 is opened on one side of the fixed plate 6. Two threaded posts 9 are fixed to the top surface of the support plate 1. The fixed bracket 2 and the threaded posts 9 are slidably inserted. The threaded posts 9 are threaded with nuts through the top surface of the fixed bracket 2.

[0024] In use, the protective arm body 3 is installed between the support plate 1 and the fixed bracket 2. The fixed bracket 2 is fixed to the body of the stand-on warehouse vehicle by the fastening of the threaded post 9 and the nut, providing a rotation fulcrum and load-bearing support for the protective arm body 3. The protective arm body 3 is made of high-strength aluminum alloy. When the protective arm body 3 flips upward, the upper limit plate 4 flips upward synchronously with the protective arm body 3 and cooperates with the upper limit groove 7 to form a limit, thereby limiting the maximum angle of upward flipping of the protective arm body 3.

[0025] Conversely, when the protective arm body 3 flips downward, the lower limit plate 5 flips downward synchronously with the protective arm body 3 and abuts against the lower limit groove 8, thereby limiting the maximum angle at which the protective arm body 3 flips downward.

[0026] Workers can manually flip the protective arm body 3 to switch between three states: flipped up, horizontal protection, and flipped down completely. By adjusting the flipping angle of the protective arm body 3, both space occupation and protection requirements can be considered in transportation and operation conditions, thereby reducing space occupation during transportation and reducing related costs.

[0027] like Figure 2 and Figure 5 As shown, two positioning plates 11 are fixed on the top surface of the base plate 10. A positioning pin 12 is inserted between the two positioning plates 11. A movable limiting plate 13 is inserted on the positioning pin 12. A movable limiting connecting plate 14 is provided on one side of the movable limiting connecting plate 13. Several fixing holes 15 are opened on one side of the movable limiting connecting plate 14. Bolts are inserted into the fixing holes 15. One end of the bolt passes through the fixing hole 15 and is threaded into the interior of the movable limiting plate 13.

[0028] During use, workers can first remove the bolts between the movable limiting connecting plate 14 and the movable limiting plate 13 according to their own height or body shape requirements, then adjust the movable limiting connecting plate 14 to the target fixing hole 15 and tighten it again. The other end of the movable limiting connecting plate 14 is assembled with the top surface of the base plate 10. The above-mentioned assembly position adjustment can simultaneously change the installation height of the base plate 10 and the protective arm body 3 on the stand-on-drive warehouse vehicle body, thereby expanding the applicability of the stand-on-drive warehouse vehicle.

[0029] like Figure 2 As shown, two support feet 16 are fixed to the bottom surface of the base plate 10, and a reinforcing plate 17 is provided below the base plate 10. One side of the reinforcing plate 17 is fixed to one side of the support feet 16, and handles 18 are fixed to both ends of the protective arm body 3.

[0030] During use, the operator holds the handle 18 to rotate the protective arm body 3, keeping the palm away from the clamping gap between the protective arm body 3 and the support plate 1 and the fixed bracket 2, reducing the risk of pinching injury. The reinforcing plate 17 and the support foot 16 provide support and reinforcement to the base plate 10, transferring and distributing the load generated by rotating the protective arm body 3 to the vehicle body, preventing local stress concentration in the base plate 10 or support foot 16 that could lead to cracking or loosening, and improving the structural reliability of the protective arm assembly for long-term use.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
