[0043] The following is combined with Figures 1 to 6 This describes the bracket structure and engineering machinery according to embodiments of the present utility model.

[0044] According to an embodiment of this utility model, in one aspect, a bracket structure is provided, including a bracket body 1, a fixing bracket 3, and a storage box 5. Specifically, the bracket body 1 is suitable for mounting on a vehicle frame; specifically, taking a crane as an example, the bracket body 1 is mounted at the rear of the vehicle frame. Figure 1 and Figure 3 As shown, the bracket body 1 is provided with a support platform 101 for supporting the outrigger pads 2. Specifically, multiple outrigger pads 2 are stacked on the support platform 101 along a first direction. Figure 2 and Figure 4 As shown, the fixing bracket 3 is disposed on the bracket body 1, and the fixing bracket 3 and the support platform 101 are spaced apart along the first direction. The fixing bracket 3 is used to fix the spare tire 4. Figure 3 and Figure 4 As shown, the storage box 5 is disposed between the support platform 101 and the fixed bracket 3, and the bracket body 1 has an internal cavity 102, in which the storage box 5 is disposed.

[0045] This design, by fixing the main body 1 of the bracket to the rear of the vehicle frame, creates a multi-functional layered space. The upper support platform 101 can hold the outrigger pads 2, the lower fixing bracket 3 can hold the spare tire 4, and the middle storage box 5 can be used to store ropes and other tools used to secure the outrigger pads 2. This fully utilizes the vertical installation space of the bracket, simultaneously meeting the transport needs of the outrigger pads 2 and the spare tire 4, while also providing storage, effectively avoiding the problems of cluttered placement and easy loss of ropes and other tools. The overall structure is simple and neat, flexible and convenient to use, greatly enhancing the user experience.

[0046] Optionally, in some embodiments of this utility model, such as Figure 4As shown, the bracket body 1 includes a support plate 103, a support frame 104, and a pair of side plates 105. The support plate 103 has a support platform 101; specifically, the upper surface of the support plate 103 forms the support platform 101. The support frame 104 is spaced apart from the support plate 103 along a first direction, as shown... Figure 3 As shown, the storage box 5 is positioned between the support plate 103 and the support frame 104, and as... Figure 5 As shown, the fixed bracket 3 is located on the side of the support frame 104 away from the support plate 103.

[0047] A pair of side plates 105 are respectively disposed on both sides of the support plate 103 and the support frame 104 to enclose and form a receiving cavity 102. The side plates 105 are connected to both the support plate 103 and the support frame 104, for example, by welding, so that the bracket body 1 forms a welded frame, ensuring its overall connection performance. The side plates 105 are provided with mounting holes 1051 for connection to the vehicle frame. Specifically, they can be connected and fixed by inserting pins 7 or bolts into the mounting holes 1051. If pins 7 are used for connection, such as... Figure 6 As shown, a pin pin 8 can also be provided at the end of the pin 7 to prevent the pin 7 from accidentally falling off. It should be noted that the number of mounting holes 1051 can be determined according to actual design requirements, for example, such as... Figure 6 As shown, the upper and lower ends of the side plate 105 are respectively provided with mounting holes 1051. Correspondingly, the frame is provided with matching mounting holes. The side plate 105 and the frame are reliably fixed by means of pins 7 or bolts.

[0048] With this configuration, the main body 1 of the bracket forms a stable support frame, which greatly improves the overall torsional stiffness, ensures that the bracket remains structurally stable when under stress, and optimizes the spatial layout of the bracket, thereby improving space utilization.

[0049] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, a pair of side plates 105 extend outwards from the support frame 104 along a first direction, and a receiving space 106 for accommodating the spare tire 4 is formed between the pair of side plates 105. The fixing bracket 3 is located within the receiving space 106. This arrangement, with the side plates 105 extending outwards from the support frame 104 along the first direction, reduces the risk of deformation or breakage of the side plates 105, enhances the overall structural strength of the bracket body 1, and improves the reliability of the structure. Simultaneously, the enveloping design of the receiving space 106 provides a certain degree of protection for the spare tire 4, effectively reducing collisions or friction between the spare tire 4 and surrounding structures.

[0050] Optionally, in some embodiments of this utility model, such as Figure 2As shown, the bracket body 1 also includes a connecting beam 107, which is disposed on the side of the side plate 105 facing the vehicle frame and between a pair of side plates 105. Specifically, the connecting beam 107 and the side plate 105 can be welded together to enhance the connection strength. With this configuration, the pair of side plates 105 are connected into an integral frame structure by the connecting beam 107. Compared to a single side plate 105, the frame structure can more effectively distribute the loads generated by the spare tire weight, vehicle vibration, or inertial forces, avoiding bending or deformation of the side plate 105 due to localized stress, and significantly improving the structural rigidity and deformation resistance of the bracket body 1.

[0051] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, a tilting clearance portion 1052 is also provided on the side of the pair of side panels 105 facing away from the frame. With this configuration, the removal and placement of the spare tire 4 usually requires operation from the outside of the side panel 105. The tilting clearance portion 1052 can expand the operating area on the outside of the side panel 105 (such as the space for inserting fingers or tools), avoid the inconvenience caused by the edge of the side panel 105 obstructing the operation (such as scratching the hand or the inability to apply force with tools), and improve the convenience of installation and removal.

[0052] Optionally, in some embodiments of this utility model, such as Figure 3 As shown, a pair of side plates 105 and / or support plates 103 are provided with weight-reducing holes 108. It should be noted that the number, size, and shape of the weight-reducing holes 108 can be specifically determined according to actual design requirements, for example, as... Figure 2 and Figure 3 As shown, the side plate 105 and the support plate 103 are respectively provided with multiple weight reduction holes 108. With this arrangement, the weight reduction holes 108 remove material from the non-core load-bearing areas of the side plate 105 or the support plate 103, which can ensure the reliability of the structure and reduce the overall weight of the bracket body 1, thereby reducing costs and achieving a clever balance between lightweight and functionality.

[0053] Optionally, in some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the support platform 101 is provided with a limiting protrusion 1011, which is used to abut against the outrigger pad 2. It should be noted that the number, size, and shape of the limiting protrusions 1011 can be specifically determined according to actual design requirements. For example, ... Figure 3 As shown, there are multiple limiting protrusions 1011, which are spaced apart. This arrangement forms a boundary for the outrigger pad 2 through the limiting protrusions 1011, preventing the outrigger pad 2 from accidentally detaching from the support platform 101 under extreme conditions such as sudden braking or bumpy roads, thus improving driving safety.

[0054] Optionally, in some embodiments of this utility model, such as Figure 4 As shown, the bracket structure also includes multiple rope fixing parts 6, which are spaced apart circumferentially along the support platform 101. The rope fixing parts 6 are used to fix rope tools, which are suitable for fixing the outrigger pads 2. It should be noted that in actual use, the outrigger pads 2 are fixed to the bracket body 1 by ropes. The rope fixing parts 6 are arranged at appropriate locations as needed to fix the ropes, thereby reliably securing the outrigger pads 2 and ensuring safe and reliable use during transportation. Optionally, the rope fixing part 6 includes a hook 601 and a rope tensioner 602. The hook 601 can fix the rope head, and the rope tensioner 602 can achieve unidirectional rope tightening. Its installation position can be determined according to actual usage requirements.

[0055] Optionally, in some embodiments of this utility model, such as Figure 5 As shown, the fixed bracket 3 includes a connecting frame 301, a fixing plate 302, and multiple fasteners 303. Specifically, the connecting frame 301 is connected to the side of the support frame 104 opposite to the support plate 103, for example, by welding. The fixing plate 302 is disposed on the side of the connecting frame 301 opposite to the support frame 104, for example, by welding. Multiple fasteners 303 are spaced apart circumferentially along the fixing plate 302, and the fasteners 303 are used to fix the spare tire 4 and the fixing plate 302. Optionally, the connecting frame 301 and the fixing plate 302 can adopt a triangular support structure design, with the fasteners 303 disposed at the corner positions. The fasteners 303 can be bolts, which are welded to the fixing plate 302 and then fastened to the corresponding connecting holes on the spare tire 4 to fix the spare tire 4 to the bracket.

[0056] This configuration, through the cooperation of the connecting frame 301 and the fixing plate 302, improves the structural stability and load distribution capability, increases the fatigue life of the overall structure, significantly enhances the fixing reliability, and ensures a more stable fixing effect for the spare tire 4.

[0057] Optionally, in some embodiments of this utility model, such as Figure 3As shown, the storage box 5 includes a box body 501, a cover plate 502, and a lock 503. Specifically, the box body 501 is disposed between the support plate 103 and the support frame 104. Optionally, the box body 501 can be welded or bolted to the support frame 104. The box body 501 is disposed within the receiving cavity 102 to reduce the occupation of external space and fully utilize the vertical layering space of the bracket. The side of the box body 501 facing away from the frame has an opening for easy access to tools. The cover plate 502 is rotatably connected to the box body 501, for example, via a hinge or pivot. The cover plate 502 is used to open or close the opening to prevent tools such as ropes from slipping out. The lock 503 is used to secure the cover plate 502 and the box body 501 to prevent the cover plate 502 from accidentally flipping open. It should be noted that the lock 503 is a commonly used device in related technologies, so its specific structure will not be described in detail here. Furthermore, to facilitate the categorization and placement of tools and to fully utilize the internal space of the housing 501, the interior of the housing 501 can be divided into multiple independent chambers, for example, such as... Figure 3 As shown, the box 501 has two independent chambers to divide the opening into two, and a cover 502 and a lock 503 are respectively provided to ensure the reliability of the storage box 5.

[0058] According to an embodiment of this utility model, another aspect provides an engineering machine, including the bracket structure as described in the various embodiments above. Optionally, the engineering machine is a crane, excavator, etc. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the bracket structure described above, and therefore will not be repeated here.
