Description

Technical Field

[0001] This utility model relates to the field of work platform technology, and more specifically, to a telescopic work platform for aerial work vehicles. Background Technology

[0002] In the existing technology field, telescopic work platforms for aerial work vehicles generally suffer from problems such as complicated operation and inconvenient deployment. Specifically, the deployment process of traditional telescopic platforms usually requires operators to perform multiple steps and high-intensity manual operations, including releasing the locking mechanism, adjusting the support structure, and operating the hydraulic system. This design not only prolongs the equipment preparation time, but also increases the labor intensity and safety risks of operators.

[0003] When the operation is completed and the active and passive stages need to be restored to their initial positions, the locking mechanism design in the prior art has obvious defects. These fixing devices usually adopt complex mechanical interlocking structures or multi-point fixing methods. The unlocking process is cumbersome and time-consuming. Operators need to manually loosen multiple fixing points one by one, and sometimes even special tools are needed to complete the unlocking operation.

[0004] When the equipment is in place and ready for operation, reliably securing the active and driven stages is a key step to ensure operational safety. However, existing securing mechanisms are often inefficient and cannot achieve fast and reliable locking. Traditional securing methods usually rely on mechanical means such as bolt locking, pin connection, or friction locking. These methods are not only time-consuming, but also require operators to accurately align the securing points. Utility Model Content

[0029] Please see Figures 1-7 A telescopic work platform for aerial work vehicles includes an active platform 1, on which a telescopic assembly is provided. The telescopic assembly includes a driven platform 2 and a guide rod 3. The driven platform 2 is slidably connected to the active platform 1, and the guide rod 3 is connected to the driven platform 2. A top rail 4 is installed on the active platform 1, and the guide rod 3 is slidably connected to the top rail 4. A control plate 5 is connected to one end of the guide rod 3. A guardrail 6 is installed on the active platform 1. A stabilizing assembly is provided between the active platform 1 and the driven platform 2. The stabilizing assembly includes a baffle 7 and a stabilizing sleeve 8. The baffle 7 is set on the active platform 1, and the stabilizing sleeve 8 is installed on the baffle 7. A stabilizing rod 9 is slidably connected to the stabilizing sleeve 8.

[0030] A rotating door 10 is rotatably connected to the active platform 1, and a rotating cover 11 is rotatably connected to the active platform 1, with the rotating cover 11 overlapping the rotating door 10.

[0031] Bolt 12 is provided for detachable installation between the rotating cover 11 and the rotating door 10.

[0032] A stabilizing plate 13 is connected to the stabilizing rod 9. The stabilizing plate 13 is in close contact with the driven platform 2. Stabilizing holes 14 are evenly opened on the driven platform 2. The stabilizing holes 14 are adapted to the stabilizing rod 9. A rotating plate 15 is rotatably connected to the stabilizing sleeve 8. A rotating rod 16 is connected to the rotating plate 15.

[0033] The rotating rod 16 has a stabilizing groove 17, and the stabilizing sleeve 8 has a sliding sleeve 18 that is adapted to the stabilizing groove 17. The sliding sleeve 18 has a through groove 19 that is adapted to the rotating rod 16.

[0034] In this embodiment, when the operator needs to get off the active platform 1, the bolt 12 is removed from the rotating cover 11 and the rotating door 10. Then, the rotating cover 11 is rotated open along the guardrail 6, and the rotating door 10 is rotated open along the active platform 1. The user can then get off the active platform 1 to carry out subsequent operations. When the driven platform 2 needs to be slid along the active platform 1 to a suitable position for operation, the rotating plate 15 is rotated along the stabilizing sleeve 8. When it rotates, the rotating rod 16 is rotated so that it is aligned with the through groove 19 on the moving sleeve 18. This releases the fixation on the moving sleeve 18. Under the action of the elastic potential energy of the first spring 20, the moving sleeve 18 is driven to slide along the stabilizing sleeve 8.

[0035] Please see Figure 5-7 As an embodiment of the telescopic work platform for aerial work vehicles with locking components: a locking component is provided on the stabilizing sleeve 8. The locking component includes a first spring 20 and an unfolding plate 21. The first spring 20 is connected between the stabilizing sleeve 8 and the movable sleeve 18. The unfolding plate 21 is rotatably connected to the stabilizing sleeve 8. The unfolding plate 21 is in close contact with the inner side of the movable sleeve 18. A second spring 22 is provided between the unfolding plate 21 and the stabilizing sleeve 8.

[0036] A contact rod 23 is slidably connected to the stabilizing sleeve 8. A contact block 24 is connected to one end of the contact rod 23. The contact block 24 abuts against the unfolding plate 21. A third spring 25 is sleeved on the contact rod 23. The two ends of the third spring 25 are connected to the stabilizing sleeve 8 and the contact block 24.

[0037] The other end of the contact rod 23 is connected to an abutment block 26, and the stabilizing rod 9 is provided with an abutment groove 27, which is adapted to the abutment block 26.

[0038] More specifically, when the movable sleeve 18 slides along the stabilizing sleeve 8, it releases the contact with the unfolding plate 21. Under the action of the elastic potential energy of the second spring 22, the unfolding plate 21 rotates along the stabilizing sleeve 8. During its rotation, it releases the contact with the contact block 24. Under the action of the elastic potential energy of the third spring 25, the contact rod 23 slides along the stabilizing sleeve 8. When the contact rod 23 slides, the abutment block 26 moves out of the abutment groove 27 of the stabilizing rod 9, thereby releasing the fixation between the stabilizing sleeve 8 and the stabilizing rod 9. At this time, the stabilizing rod 9 is slid out along the stabilizing sleeve 8. The driven stage 2 slides along the top rail 4 using the guide rod 3. After sliding to the appropriate position, the stabilizing rod 9 is inserted into the stabilizing sleeve 8 through the appropriate stabilizing hole 14 on the driven stage 2, thereby completing the fixation between the driving stage 1 and the driven stage 2.

[0039] In summary, during the use or operation of the overall equipment: when the operator needs to get off the active platform 1, the bolt 12 is removed from the rotating cover 11 and the rotating door 10. Then, the rotating cover 11 is rotated open along the guardrail 6, and the rotating door 10 is rotated open along the active platform 1. The user can then walk off the active platform 1 to carry out subsequent operations. When the driven platform 2 needs to be slid along the active platform 1 to a suitable position for operation, the rotating plate 15 is rotated along the stabilizing sleeve 8. When it rotates, the rotating rod 16 is rotated so that it is aligned with the through groove 19 on the moving sleeve 18. This releases the fixation on the moving sleeve 18. Under the action of the elastic potential energy of the first spring 20, the moving sleeve 18 is driven to slide along the stabilizing sleeve 8.

[0040] As the movable sleeve 18 slides along the stabilizing sleeve 8, it releases the contact with the unfolding plate 21. Under the action of the elastic potential energy of the second spring 22, the unfolding plate 21 rotates along the stabilizing sleeve 8. During its rotation, it releases the contact with the contact block 24. Under the action of the elastic potential energy of the third spring 25, the contact rod 23 slides along the stabilizing sleeve 8. As the contact rod 23 slides, the abutment block 26 moves out of the abutment groove 27 of the stabilizing rod 9, thereby releasing the fixation between the stabilizing sleeve 8 and the stabilizing rod 9. At this time, the stabilizing rod 9 is slid out along the stabilizing sleeve 8. The driven stage 2 slides along the top rail 4 using the guide rod 3. After sliding to the appropriate position, the stabilizing rod 9 is inserted into the stabilizing sleeve 8 through the appropriate stabilizing hole 14 on the driven stage 2, thereby completing the fixation between the driving stage 1 and the driven stage 2.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents.
