Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a wheeled crane outrigger pad. Background Technology

[0002] Wheeled cranes are widely used for lifting operations at construction sites. These cranes require their outriggers to be extended for operation. Construction sites often have complex ground conditions, such as uneven or soft ground, necessitating the use of outrigger pads to provide stable, level, and secure support. Commonly used materials include sleepers, cement slabs, and steel plates. However, due to uneven ground, while these pads provide support, they have several drawbacks. First, if the ground is sloping, the pad will also be tilted, resulting in a smaller contact area between the crane outriggers and the pad, leading to insufficient stability and a tendency to slip. Second, if the ground is wet and soft, the weight of the load can cause the pad to sink further into the ground after the outriggers are secured, leading to an imbalance in the crane outriggers and posing a safety hazard. Therefore, this paper proposes wheeled crane outrigger pads to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wheeled crane outrigger pad, which solves the problems mentioned in the background section.

[0011] This utility model provides a wheeled crane outrigger pad, which has the following beneficial effects:

[0012] 1. The outrigger pad of this wheeled crane can drive the drive block by activating the bidirectional hydraulic rod, which in turn drives the adjusting rod. The adjusting rod can drive the balance component to descend. The height of the four sides of the plate can be adjusted according to the ground level to ensure that the upper surface of the plate is in a horizontal state, thereby increasing the contact area with the crane outrigger and improving the balance of the crane.

[0013] 2. The outrigger pads of this wheeled crane can be driven by activating the electric telescopic rod, which in turn drives the positioning component, causing the positioning component to move laterally and embed itself into the wet, soft soil. This prevents the plate from settling excessively due to the increased weight after the crane outriggers are erected, effectively ensuring the plate's position is fixed and improving the crane's stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a wheeled crane outrigger pad, including a plate body 1. Balance grooves 2 are formed on all four sides of the plate body 1. A bidirectional hydraulic rod 3 is fixedly installed inside the balance groove 2. A drive block 4 is fixedly installed on the output shaft of the bidirectional hydraulic rod 3. When the left drive block 4 is not driven, it is located at the leftmost position on the outer surface of the guide post 5; when the right drive block 4 is not driven, it is located at the rightmost position on the outer surface of the guide post 5. This ensures that the balance component 7 can be fully moved out of the plate body 1, improving the adjustment range. A guide post 5 is movably installed inside the drive block 4. The guide post 5 is fixedly installed inside the balance groove 2, guiding the drive block 4 and making the driving process of the drive block 4 more stable. A mounting frame is provided at the bottom of the drive block 4, and an adjusting rod 6 is installed in the mounting frame. A balance component 7 is installed at the other end of the adjusting rod 6, and an insert is fixedly installed at the bottom of the balance component 7. 8. The bottom of the insert 8 is shaped like a pointed triangle, which makes it easier for the insert 8 to be embedded in the soil, thereby improving the stability of the plate 1. The interior of the balance component 7 is provided with an installation groove, in which a positioning component 10 is provided. An extension plate is provided on one side of the positioning component 10, and a through groove adapted to the extension plate is provided on one side of the balance component 7, which makes it easy for the extension plate to enter the soil in parallel, thereby preventing the plate 1 from settling excessively. A slider 9 is fixedly installed at the bottom of the positioning component 10. The slider 9 is shaped like a T-shaped protrusion. The interior of the balance component 7 is provided with a T-shaped groove adapted to the slider 9. The slider 9 can limit the positioning component 10, making the positioning component 10 more stable when it moves. The slider 9 is movably installed inside the balance component 7. An electric telescopic rod 11 is fixedly installed on one side of the balance groove 2, and a power component 12 is fixedly installed on the output shaft of the electric telescopic rod 11.

[0022] Please see Figure 4 and Figure 5A support column 13 is fixedly installed on the inner side of the balancing component 7. The positioning component 10 has a displacement groove adapted to the support column 13 inside. One side of the positioning component 10 is an inclined surface. The lower left side of the power component 12 is an inclined surface adapted to the positioning component 10, which allows the power component 12 to drive the positioning component 10 more smoothly. A limit block 14 is fixedly installed at the other end of the support column 13. A return spring 15 is provided on the outer surface of the support column 13. When the positioning component 10 moves, it will squeeze the return spring 15. When the power component 12 returns to its original position, the elastic force generated by the elastic deformation of the positioning component 10 can assist the positioning component 10 in returning to its original position. The positioning component 10 is movably installed on the outer surface of the support column 13.

[0023] In summary, when using this wheeled crane outrigger pad, the user first needs to observe the terrain of the placement location, then activate the bidirectional hydraulic rod 3 to drive the drive block 4, which in turn drives the adjusting rod 6. The adjusting rod 6 then lowers the balance component 7 to adjust the height of the four sides of the plate 1, ensuring that the upper surface of the plate 1 is horizontal, thereby increasing its contact area with the crane outrigger. Next, locate the extended balance component 7 and activate its electric telescopic rod 11 to drive the power component 12, which in turn drives the positioning component 10. This causes the positioning component 10 to move laterally and embed itself into the soft, wet soil, thus preventing the plate 1 from excessively settling due to the increased weight after the crane outrigger is raised.
