[0040] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0041] According to an embodiment of this utility model, a pad transfer device 100 is provided, which is installed at the rear of the main body 210 of an engineering machinery frame. It enables rapid relocation and adapts to diverse scenario requirements, saves on the transfer cost of outrigger pads, and meets the requirements for on-road and underbody rear protection during long-distance relocation.

[0042] The pallet transfer device 100 includes a frame 10, a connecting assembly 20, and a rear protective component 30.

[0043] The frame 10 is used to hold the pads 220. There can be multiple pads 220. The frame 10 may have a receiving space to accommodate multiple pads 220 and prevent the pads 220 from falling out.

[0044] The connecting assembly 20 connects the frame 10 and the frame body 210 to fix the pad transfer device 100 to the frame body 210.

[0045] The rear protective member 30 is connected to the rear side of the frame 10, wherein the rear protective member 30 is at least partially lower than the main frame 210. Here, "rear side" refers to the side of the construction machinery in the longitudinal direction. The rear protective member 30 may be entirely lower than the main frame 210, or it may be partially lower than the main frame 210. For example, the distance between the rear protective member 30 and the ground may be between 50cm and 55cm.

[0046] The pad transfer device 100 is installed at the rear of the main body 210 of the construction machinery frame. The pad transfer device 100 is equipped with a rear protective component 30, which not only meets the requirements for road and undercarriage rear protection, but also enables long-distance transportation and construction with outrigger pads without disassembly, reducing time and labor costs. In addition, it can also prevent following vehicles from being caught in the chassis of the construction machinery, ensuring the safety of the personnel in the following vehicle in the event of a rear-end collision.

[0047] In some embodiments, refer to Figure 2 The rear protective component 30 includes a crossbeam 31 and two connecting beams 32. The two ends of the connecting beams 32 are respectively fixed to the frame 10 and the crossbeam 31. The two connecting beams 32 are spaced apart along the left and right directions of the construction machinery. The crossbeam 31 is lower than the frame body 210.

[0048] The crossbeam 31 extends in the left-right direction. The crossbeam 31 can be made of materials such as stainless steel, aluminum alloy, or carbon fiber reinforced composite. The two ends of the connecting beam 32 can be welded and fixed to the connecting frame 10 and the crossbeam 31, respectively. The connecting beam 32 can also be made of materials such as stainless steel, aluminum alloy, or carbon fiber reinforced composite. The connecting beam 32 can be a hollow structure to better absorb energy during impact.

[0049] The rear protective component 30 includes a crossbeam 31 and a connecting beam 32. The crossbeam 31 provides a collision protection effect, while the connecting beam 32 can further absorb the energy during the impact, playing a certain buffering role and ensuring the safety of the occupants of the following vehicle in the event of a rear-end collision.

[0050] In some embodiments, the connecting beam 32 includes a vertical section 321 and a bent section 322. The vertical section 321 is fixedly connected to the frame 10, and the bent section 322 is connected to the crossbeam 31.

[0051] Vertical segment 321 is a beam structure extending vertically. Bent segment 322 is a beam structure extending diagonally downwards.

[0052] The connecting beam 32, including the vertical section 321 and the bent section 322, can further absorb the energy during an impact, playing a certain buffering role and ensuring the safety of the people in the following vehicle during a rear-end collision.

[0053] In some embodiments, the crossbeam 31 is provided with a mounting groove 311 for mounting a detection component. The detection component may be, for example, a radar sensor, a rear-facing camera, etc.

[0054] The crossbeam 31 is provided with a mounting slot 311 for installing the detection components. The structure of the crossbeam 31 enables the rear protective component 30 to have multiple functions.

[0055] In some embodiments, refer to Figure 6 Along the left and right direction, the two ends of the crossbeam 31 are shortened to or flush with the sides of the frame body 210.

[0056] The two ends of the crossbeam 31 are shortened to the sides of the frame body 210, so as not to occupy external space outside the frame body 210 and reduce the occurrence of scratches. The two ends of the crossbeam 31 are flush with the sides of the frame body 210, which can increase the protection range.

[0057] In some embodiments, the frame 10 has a frame structure and a receiving space for accommodating the pads 220; wherein, a plurality of pads 220 are stacked along the front-back direction of the engineering machinery, and the thickness direction of the pads 220 is consistent with the front-back direction.

[0058] Typically, the thickness of the pad 220 is much smaller than its length and width. Multiple pads 220 are stacked along the front-back direction of the construction machinery. The thickness direction of the pad 220 is consistent with the front-back direction, which can reduce the space occupied in the front-back direction, making the frame 10 thinner and the pad transfer device 100 more compact, thus meeting the requirements for road use and safety.

[0059] In some embodiments, the frame 10 has a plurality of upper openings, which are spaced apart along the front-to-back direction.

[0060] The pad 220 can be inserted through the top opening. Multiple pads 220 can be spaced apart by baffles between two adjacent top openings to reduce the risk of damage caused by collisions between the pads 220.

[0061] In some embodiments, a first mounting plate (not shown) is provided at the rear of the frame body 210, and the first mounting plate has a first through hole; see reference Figure 3 and Figure 4 The connecting assembly 20 includes a second mounting plate 21, a pin 22, and a clamping pin 23. The second mounting plate 21 is provided with a second through hole 211, and the pin 22 is provided with a third through hole extending radially therefrom. The pin 22 passes through the first through hole and the second through hole 211, and the clamping pin 23 passes through the third through hole to restrict the pin 22 in the first through hole and the second through hole 211, thereby fixing the pad transfer device 100 to the frame body 210.

[0062] The structure of the first mounting plate can be referenced from that of the second mounting plate. For example, both the first and second mounting plates have through holes on their top, bottom, left, and right sides, and each through hole is fitted with a pin 22.

[0063] This improves installation convenience and enables rapid installation.

[0064] In some embodiments, the outer periphery and / or bottom side of the frame 10 is covered by an outer cover 40. Figure 1 (As shown).

[0065] The outer cover 40 can be made of stainless steel, aluminum, etc. The outer cover 40 can be welded and fixed to the frame 10.

[0066] The outer cover 40 covering the outer periphery and / or bottom of the frame 10 reduces the entry of foreign objects and keeps the appearance clean.

[0067] According to an embodiment of the present invention, another aspect provides an engineering machinery, comprising: a frame body 210 and a pad transfer device 100 according to any embodiment of the first aspect. The engineering machinery may be a crane.
