Description

Technical Field

[0001] This utility model relates to the field of concrete pump truck technology, and in particular to a steel structure for the outriggers of a pump truck. Background Technology

[0002] In the field of engineering construction, the pump truck is the core equipment for concrete transportation. Its stability and safety during operation are of paramount importance. The outrigger steel structure is a key component to ensure this performance. The outrigger steel structure needs to bear multiple forces such as the weight of the pump truck itself, the load of the transported materials, and the vibration of operation. It is the basic support for the pump truck to achieve stable operation.

[0003] A search revealed Chinese patent publication number CN202811629U, which discloses a hydraulic cylinder for a cement pump truck's outriggers. The cylinder is characterized by a square base welded to one end of the cylinder barrel, a guide sleeve bolted to the other end of the cylinder barrel, a piston rod fitted into the guide sleeve and inserted into the cylinder barrel, and a dustproof ring, a step seal, a first support ring, a piston rod sealing ring, an O-ring, and a retaining ring installed on the guide sleeve. A piston is installed at the end of the piston rod that extends into the cylinder barrel, and a Gladley ring and a second support ring are installed on the piston.

[0004] The aforementioned patent specification states that "this utility model has a compact structure, good sealing and pressure retention, and features long-term pressure resistance and good sealing performance, making it suitable for use on cement pump trucks." While this ensures the sealing performance of the pump truck, it cannot guarantee its stability, resulting in a high risk of overturning and poor stabilization. Therefore, a steel structure for the outriggers of the pump truck is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a steel structure for the outriggers of a pump truck, which aims to improve the poor stability of some pump truck devices.

[0006] The present application provides a concrete pump truck outrigger steel structure with the following technical solution: it includes multiple supporting shells, a supporting mechanism is fixedly connected to the outside of the supporting shells, a reinforcing mechanism is fixedly connected to the inside of the supporting shells, the supporting mechanism includes a supporting component for support, the supporting component is fixedly connected to the outside of the multiple supporting shells, a second stiffening rib is fixedly connected to the bottom of the multiple supporting shells, a connecting base plate is fixedly connected to the bottom of the second stiffening rib, a first supporting rod is fixedly connected to the top of the supporting component, multiple first supporting crossbars are fixedly connected to the top of the first supporting rod, a second supporting rod is fixedly connected to the top of the multiple supporting shells, multiple second supporting crossbars are fixedly connected to the top of the second supporting rod, and an arc-shaped crossbar is fixedly connected to the bottom of the second supporting crossbar, i.e., the end away from the second supporting rod.

[0007] The above technical solutions enhance structural stability, enabling it to cope with complex operating environments. Stiffening ribs strengthen the connection points, the connecting base plate expands the ground contact area, reducing ground bearing pressure, and the arc-shaped crossbar optimizes force transmission and improves bending resistance. The overall design extends component life, reduces maintenance frequency, and ensures safe and efficient operation of the pump truck.

[0008] Preferably, the reinforcing mechanism includes an anti-scratch layer, a support layer is fixedly connected to the inner side of the anti-scratch layer, and a connecting layer is fixedly connected to the inner side of the support layer;

[0009] Through the above technical solutions: the anti-scratch layer can effectively resist external friction and collision, protect the internal structure, and extend the service life of the mechanism; the support layer provides stable support for the whole with its own strength; and the connection layer ensures that the support layer is firmly connected to other components, ensuring stable force transmission, and thus enhancing the overall reliability of the outrigger steel structure.

[0010] Preferably, the external fixed connection of the second supporting rod is to the top of the plurality of supporting shells, and the external fixed connection of the first supporting crossbar is to the top of the plurality of supporting shells;

[0011] The above technical solution enables the second supporting rod and the first supporting crossbar to form a stable whole with the supporting shell, enhancing the overall structure and the ability to bear loads together. It also distributes the load more evenly across multiple supporting shells, reducing the possibility of excessive local stress, and improving the support strength of the outrigger steel structure in both the lateral and longitudinal directions. This helps to cope with complex operating loads and ensures the safe and stable operation of the pump truck.

[0012] Preferably, the support assembly includes multiple connecting steel plates, the bottom of which is fixedly connected to a stiffening rib, and the top of which is fixedly connected to the bottom of the support rod.

[0013] Through the above technical solution, multiple connecting steel plates distribute the load, and the stiffening ribs enhance the structural strength of the connection parts, effectively dispersing the pressure and reducing the risk of wear and deformation at the connection between the connecting steel plates and the supporting shell. This combined structure makes the force transmission more uniform and efficient, improves the overall load-bearing capacity of the support components, ensures the stability of the outrigger steel structure during heavy-load operations, and extends the service life of the components.

[0014] Preferably, the first stiffening rib is externally fixedly connected to the outside of the plurality of supporting shells, and the second stiffening rib is externally fixedly connected to the outside of the plurality of supporting shells;

[0015] Through the above technical solution, the load of the supporting top rod is efficiently transferred to the stiffening rib through the connecting steel plate. The stiffening rib can disperse the pressure and avoid damage caused by concentrated force at the connection point. Multiple connecting steel plates work together to enhance the overall connection strength, improve the load-bearing capacity of the supporting components, and ensure the stable operation of the outrigger steel structure.

[0016] Preferably, the bottom of the arc-shaped crossbar is fixedly connected to the top of the plurality of supporting shells, the outside of the plurality of supporting crossbars is fixedly connected to the outside of the supporting shells, and the bottom of the supporting top rod is fixedly connected to the top of the plurality of connecting steel plates;

[0017] Through the above technical solutions, the force transmission is smoother, the arc design of the arc-shaped crossbar can disperse stress and reduce local wear, the connection between the second support crossbar and the support shell enhances lateral support, and the fixing of the second support top bar and the connecting steel plate makes the load transmission more even. Overall, the structural stability and load-bearing efficiency of the outrigger steel structure are improved, and the service life is extended.

[0018] Preferably, a supporting inner core is fixedly connected to the inner side of the connecting layer, and the outer side of the anti-scratch layer is fixedly connected to the inner side of the supporting outer shell.

[0019] Through the above technical solutions: the fixing of the connecting layer and the supporting core ensures the continuous and efficient transmission of force, avoids interruption of force transmission and affects the support effect, the supporting core enhances the load-bearing capacity of the overall structure, the anti-scratch layer effectively blocks external friction and collision from damaging the inner side and internal structure of the supporting shell, extends the service life of components, and improves the overall reliability and stability of the outrigger steel structure.

[0020] Preferably, the top of the reinforcing mechanism is fixedly connected to the bottom of the support assembly, and the outside of the support inner core is fixedly connected to the inside of the support outer shell;

[0021] The above technical solutions enhance the connection between the reinforcement mechanism and the support components, ensuring the directness of load transfer and avoiding force loss. The fixation of the inner support core and the outer support shell allows the force to be evenly distributed to the outer support shell, reducing the problem of excessive local stress. This enhances the synergy between the reinforcement mechanism and the overall structure, improves the overall stability and deformation resistance of the outrigger steel structure, and further ensures the stability and safety of the pump truck during operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the multi-point support design greatly improves the stability of the pump truck during operation and reduces the risk of tipping over. Multiple stiffening ribs and connecting structures enhance the overall load-bearing capacity and can adapt to complex working conditions. The symmetrical support layout makes the force evenly distributed, reduces local wear, and extends the service life of components. The modular structure facilitates installation and disassembly, improves construction efficiency, and reduces maintenance costs.

[0024] 2. In this utility model, the anti-scratch layer can effectively reduce the wear of the support shell and internal structure, extend the service life of the components, the support layer improves the structural strength of the entire reinforcement mechanism, the connection layer ensures that the components are firmly connected, avoids the support effect being affected by loose connections, and the support core concentrates the transmission of pressure, making the force distribution more reasonable, further improving the stability and reliability of the support, and ensuring the safety of pump truck operation.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0032] Example: A steel structure for the outriggers of a pump truck, referring to... Figure 1 and Figure 2The system includes multiple supporting shells 1, which form the basic frame of the entire support leg steel structure, serving to support the entire structure and connect the various components. Supporting mechanisms 2 are fixedly connected to the outside of the supporting shells 1, and reinforcing mechanisms 3 are fixedly connected to the inside of the supporting shells 1. Supporting mechanisms 2 include supporting components 23 for support. Supporting components 23 are fixedly connected to the outside of the multiple supporting shells 1. Reinforcing ribs 24 are fixedly connected to the bottom of the multiple supporting shells 1. Reinforcing ribs 24 can increase the connection area between the bottom of the supporting shell 1 and the connecting base plate 25, disperse the pressure transmitted by the supporting shells 1, prevent the bottom of the supporting shells 1 from deforming due to excessive local stress, and enhance the overall bending resistance of the supporting shells 1.

[0033] The bottom of the stiffening rib 24 is fixedly connected to the connecting base plate 25, which is directly in contact with the ground, increasing the contact area between the outrigger and the ground and ensuring the stability of the outrigger during operation. The top of the support component 23 is fixedly connected to the support rod 22, which plays a role in longitudinal support and resists pressure through its own structural strength. The top of the support rod 22 is fixedly connected to multiple support crossbars 21, which are fixed to the top of the support rod 22 and the top of the support shell 1. They transfer part of the weight of the pump truck and the lateral force generated during operation to the support rod 22 and the support shell 1. The multiple support crossbars 21 work together to enhance the stability of the lateral support and prevent the outrigger from swaying in the lateral direction.

[0034] Multiple support shells 1 are fixedly connected to the top of support rods 26 to enhance the overall support capacity. Multiple support crossbars 28 are fixedly connected to the top of support rods 26. Support crossbars 28 bear another part of the lateral load of the pump truck and transfer the force to support rods 26 and support shells 1. In cooperation with support crossbars 1 21, they provide lateral support to the pump truck from different positions and further enhance lateral stability. The bottom of support crossbars 28, that is, the end away from support rods 26, is fixedly connected to an arc-shaped crossbar 27. The arc structure allows it to better adapt to the direction of load transfer and distribute part of the load of support crossbars 28 to support shells 1 through the arc surface. At the same time, the arc design can enhance its own resistance to deformation and is not easy to break when bearing load.

[0035] The external fixed connection of the support top rod 26 is to the top of the multiple support shells 1, and the external fixed connection of the multiple support crossbars 21 is to the top of the multiple support shells 1. The support assembly 23 includes multiple connecting steel plates 231, which transmit the pressure of the support top rod 22 to the stiffening rib 232. The bottom of the multiple connecting steel plates 231 is fixedly connected to the stiffening rib 232. The stiffening rib 232 is fixed to the outside of the support shell 1, which can enhance the connection strength between the connecting steel plate 231 and the support shell 1, disperse the pressure, prevent the connection part from being damaged due to excessive force, and improve the stability of the support. The top of the connecting steel plate 231 is fixedly connected to the bottom of the support top rod 22.

[0036] The external fixed connection of stiffening rib 1 232 is to the outside of multiple supporting shells 1, the external fixed connection of stiffening rib 24 is to the outside of multiple supporting shells 1, the bottom of the arc-shaped crossbar 27 is fixedly connected to the top of multiple supporting shells 1, the external fixed connection of multiple supporting crossbars 28 is to the outside of supporting shells 1, and the bottom of supporting top bar 26 is fixedly connected to the top of multiple connecting steel plates 231.

[0037] Specifically, the top of the connecting steel plate 231 of the support component 23 is connected to the first support rod 22, and the bottom is connected to the support shell 1 via the first stiffening rib 232. The bottom of the support shell 1 is connected to the connecting base plate 25 via the second stiffening rib 24. The top of the first support rod 22 is connected to the first support crossbar 21, and the top of the support shell 1 is connected to the second support rod 26, which is connected to the second support crossbar 28. The bottom of the support shell 1 is connected to the connecting steel plate 231, and the bottom of the second support crossbar 28 is connected to the arc-shaped crossbar 27. The multi-layer connection structure disperses the load, improves the overall stability, and reduces the risk of overturning. The stiffening ribs enhance the connection strength and adapt to complex working conditions. The connecting base plate 25 increases the ground contact area and reduces ground pressure. The arc-shaped crossbar 27 optimizes force transmission. All components work together to extend service life, reduce maintenance costs, and ensure efficient and safe operation of the pump truck.

[0038] Reference Figure 3 and Figure 4 The reinforcing mechanism 3 includes an anti-scratch layer 31, which is fixed inside the supporting shell 1 and comes into direct contact with objects that may cause friction and collision. During the extension and retraction of the outriggers or during operation, it can resist external friction and collision, protect the integrity of the internal structure, and extend the service life of the reinforcing mechanism 3. A support layer 32 is fixedly connected to the inner side of the anti-scratch layer 31. Located inside the anti-scratch layer 31, it provides support for the entire reinforcing mechanism 3 through its own structural strength. When the reinforcing mechanism 3 is subjected to external pressure or impact, it ensures the overall shape and support performance of the reinforcing mechanism 3. A connecting layer 33 is fixedly connected to the inner side of the support layer 32, which connects the support layer 32 and the support core 34. It can stably transmit the force transmitted by the support layer 32 to the support core 34, while ensuring that the connection between the support layer 32 and the support core 34 is firm, avoiding relative displacement or loosening during the force process, and ensuring the continuity and stability of force transmission.

[0039] The inner side of the connecting layer 33 is fixedly connected to the supporting inner core 34, which evenly transmits the pressure to the supporting outer shell 1. At the same time, the supporting inner core 34 itself has high strength, which can enhance the overall load-bearing capacity of the supporting outer shell 1 and further improve the support stability of the entire leg steel structure. The outer side of the anti-scratching layer 31 is fixedly connected to the inner side of the supporting outer shell 1, the top of the reinforcing mechanism 3 is fixedly connected to the bottom of the supporting component 23, and the outer side of the supporting inner core 34 is fixedly connected to the inside of the supporting outer shell 1.

[0040] Specifically, the anti-scratch layer 31 reduces component wear and significantly extends the life of the mechanism; the support layer 32 enhances impact resistance and ensures structural stability under complex working conditions; the connection layer 33 ensures continuous force transmission; and the support core 34 enhances the load-bearing capacity of the outer shell, improves the overall support stability of the outriggers, reduces the operational risks of the pump truck, reduces localized losses, and lowers maintenance costs.

[0041] The implementation principle of this application embodiment is as follows: When it is necessary to support the pump truck, the position of the support crossbar 21 is fixed by assembling the support top rod 22, and the support crossbar 21 is supported at the same time. Meanwhile, the support shell 1 provides support for the support top rod 22. At the same time, the connecting steel plate 231 and the stiffening rib 232 are fixed to the bottom of the support top rod 22 to increase stability. Meanwhile, the bottom of the support shell 1 is fixed with the stiffening rib 24 and the connecting base plate 25 to increase stability, ensuring the stability of the support top rod 22 and the support crossbar 21. On the other side, an equal amount of support shell 1 is set to provide support for the support top rod 26 and the arc-shaped crossbar 27, while ensuring the stability of the position of the support crossbar 28, thereby achieving the effect of supporting the pump truck at both ends.

[0042] The outer anti-scratch layer 31 is fixed to the inside of the support shell 1 and can directly resist external friction and collision. The support layer 32 inside the anti-scratch layer 31 provides support for the entire reinforcement mechanism 3 through its own structural strength. The connecting layer 33 inside the support layer 32 firmly connects the support layer 32 to the support core 34. The support core 34 is fixed inside the support shell 1 and serves as the core load-bearing component, which concentrates the pressure and transmits it to achieve the function of strengthening the stability of the support.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
