[0002] In the prior art, the locking mechanism of the folding arm may be relatively single and lack multiple locking protections. During movement or storage, if it encounters strong external impacts or vibrations, the folding arm is prone to looseness or even dislocation, increasing the instability and safety hazards of the work vehicle. Especially when a key component such as a support oil cylinder fails, the existing locking mechanism may not be able to effectively prevent the complete dislocation of the folding arm, which may lead to more serious safety accidents. At the same time, the docking and locking process of the folding arm in the prior art mostly uses chains or ropes for fixation, requiring a lot of manual intervention and complex manual operations. This not only increases the operation difficulty but also prolongs the operation time and reduces the overall operation efficiency. During the unlocking process, similarly, it requires cumbersome steps and a large amount of labor input, which is not conducive to quick response and efficient operation.

The embodiments of the present utility model will be described below according to its overall structure.

[0022] Referring to Figures 1 to 4 , in the embodiment of the present utility model, a rapid docking device for the folding arm of an aerial work vehicle includes: a work vehicle body 1, a fixed bracket 2 is fixedly connected above the work vehicle body 1, a first folding arm 3 is rotatably connected inside the fixed bracket 2, a first support oil cylinder 4 is rotatably connected inside the fixed bracket 2, the movable end of the first support oil cylinder 4 is rotatably connected to the side surface of the first folding arm 3, a folding arm rapid docking and locking mechanism 5 is fixedly connected above the work vehicle body 1 at a position below the first folding arm 3, a first rotating seat 6 is rotatably connected to the outside of the first folding arm 3, a second folding arm 7 is rotatably connected inside the first rotating seat 6, a second support oil cylinder 8 is rotatably connected to the inside of the first folding arm 3, a third support oil cylinder 9 is rotatably connected below the second folding arm 7, the movable end of the third support oil cylinder 9 is rotatably connected to a support arm fixedly connected to the side surface of the work platform 11, a second rotating seat 10 is rotatably connected to the outside of the second folding arm 7, and a work platform 11 is arranged below the second rotating seat 10. Card slots 12 are symmetrically opened on both sides of the first folding arm 3, a guiding block 13 is fixedly connected inside the card slots 12, the cross section of the guiding block 13 is designed as an inverted triangle, and the inside of the second rotating seat 10 is rotatably connected to a support arm fixedly connected to the side surface of the work platform 11;

[0023] The quick docking and locking mechanism 5 of the folding arm includes a fixed base 51. Inside the fixed base 51, a buffer soft gasket 52 is fixedly connected. Inside the fixed base 51, an electric telescopic rod 53 is fixedly connected. The movable end of the electric telescopic rod 53 is fixedly connected to a support plate 54. A guiding through hole 55 is formed on the side of the support plate 54. An active clamping plate 56 is arranged on the side of the support plate 54. A clamping position top block 57 is fixedly connected to the side of the active clamping plate 56. The clamping position top block 57 is adapted to the clamping position groove 12. An upper locking block 58 is fixedly connected above the active clamping plate 56. A guiding slide rod 59 is fixedly connected to the side of the active clamping plate 56. A limiting stop piece 510 is fixedly connected to the side of the guiding slide rod 59. A support spring 511 is sleeved outside the guiding slide rod 59. The guiding slide rod 59 is slidably connected with the guiding through hole 55. The support spring 511 is located between the support plate 54 and the active clamping plate 56. When the aerial work platform needs to be retracted for movement or standby after use, the movable end of the first support oil cylinder 4 contracts, causing the first folding arm 3 to rotate. At this time, the first folding arm 3 contacts the quick docking and locking mechanism 5 of the folding arm. The upper locking block 58 is squeezed by the side of the first folding arm 3, and the support spring 511 contracts. During this process, the first folding arm 3 continues to rotate until it is in close contact with the buffer soft gasket 52. At this time, the support spring 511 returns to its initial state, and the two groups of upper locking blocks 58 lock the first folding arm 3. During this process, the clamping position top block 57 is further compressed by the support spring 511 under the extrusion of the guiding clamping block 13 until the first folding arm 3 continues to rotate until it is in close contact with the buffer soft gasket 52, and the clamping position top block 57 is completely inserted into the clamping position groove 12, further locking the position of the first folding arm 3. Through double locking, the problem that the folding arm of the aerial work platform is prone to shaking during movement is solved, and the situation that the first folding arm 3 is completely displaced when the first support oil cylinder 4 is damaged is prevented. When the aerial work platform needs to be used, only need to drive the electric telescopic rod 53 to contract to release the lock on the first folding arm 3, and then perform operations.

[0024] The working principle of the present utility model is: when the aerial work platform is used up and needs to be folded for movement or storage, first control the movable ends of the first support oil cylinder 4, the second support oil cylinder 8, and the third support oil cylinder 9 to contract, gradually reduce the height of the working platform 11, and reduce the angle between the first folding arm 3 and the second folding arm 7;

[0025] As the movable end of the first support oil cylinder 4 continues to contract, the first folding arm 3 begins to rotate around its rotation point and gradually approaches the folding arm quick docking and locking mechanism 5. During this process, the side surface of the first folding arm 3 first contacts the upper locking block 58 of the folding arm quick docking and locking mechanism 5, causing the support spring 511 to be compressed. The movable clamping plate 56 and the upper locking block 58 and the clamping position top block 57 thereon move backward. When the first folding arm 3 continues to rotate until it is in close contact with the buffer soft gasket 52, at this time, the support spring 511 returns to its initial state, and the two groups of upper locking blocks 58 lock the upper part of the first folding arm 3;

[0026] During this process, under the extrusion of the guiding block 13, the clamping position top block 57 will further compress the support spring 511 until the first folding arm 3 continues to rotate until it is in close contact with the buffer soft gasket 52, and the support spring 511 returns to its initial state. At this time, the clamping position top block 57 will completely snap into the clamping position groove 12, further locking the position of the first folding arm 3. Through double locking, the problem that the folding arm of the aerial work vehicle is prone to shaking during movement is solved, and the situation that the first folding arm 3 is completely displaced when the first support oil cylinder 4 is damaged is prevented;

[0027] When the aerial work vehicle needs to be used again, by controlling the electric telescopic rod 53 to contract, the two groups of support plates 54 are driven to move outward, thereby driving the movable clamping plate 56 and the clamping position top block 57 and the upper locking block 58 thereon to move outward, disengaging from the contact and locking state with the first folding arm 3. At this time, the first folding arm 3 can rotate freely under the action of the first support oil cylinder 4, thus restoring the normal use state of the aerial work vehicle.

[0028] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
