Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and specifically relates to a modular debugging tool for a pump truck. Background Technology

[0002] Pump truck commissioning is a crucial step in verifying the functionality and reliability of the entire pump truck or its superstructure. Currently, most existing technologies use whole-machine commissioning to verify the performance of the superstructure and undercarriage modules, without conducting detailed and in-depth research and development on the separate commissioning of these modules. This results in a long commissioning cycle, high labor intensity, and harsh working environment.

[0003] The pumping unit of a concrete pump truck refers to the assembly unit used for pumping concrete, consisting of pumping cylinders, concrete conveying cylinders, distribution directional valves, hoppers, etc. The pumping unit requires testing of multiple parameters, including the venting of the main cylinder, the airtightness of the distribution mechanism, and the parallelism of the main cylinder.

[0004] In existing technologies, there are work platforms for separately debugging the pumping unit. However, these platforms can only support and fix the pumping unit; the subframe, main valve assembly, and distribution valve assembly all require additional piping connections. During debugging, multiple sets of hydraulic lines and electrical wiring harnesses need to be disassembled and reassembled, resulting in a large workload, low debugging efficiency, and a long debugging cycle. Utility Model Content

[0005] The purpose of this invention is to provide a modular debugging tool for pump trucks to solve the problems of large workload, low efficiency and long debugging cycle in the debugging of pumping unit components in the prior art.

[0006] To achieve the above objectives, this utility model provides a modular debugging fixture for a pump truck, used to assist in the debugging of the pump truck unloading module. The pump truck unloading module includes a subframe and a pumping unit, with the pumping unit mounted on the subframe. The modular debugging fixture includes: The guide rail assembly extends along a first horizontal direction; Multiple first support frames are arranged in parallel and spaced apart along a first horizontal direction. The bottom ends of the multiple first support frames are slidably connected to the guide rail assembly. The sub-frame extends along the first horizontal direction. The top ends of the multiple first support frames are used to abut against the bottom ends of the sub-frame. The multiple first support frames are detachably connected to the sub-frame.

[0007] In some embodiments, the guide rail assembly includes two guide rail members arranged parallel to each other along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction. Each first support frame includes: two support rods extending vertically and spaced parallel to each other, the bottom ends of the support rods being slidably connected to the guide rail members; and a connecting rod connecting the two support rods.

[0008] In some embodiments, a first connecting frame is provided on both sides of the subframe, and a second connecting frame is provided on the side wall of the support rod. The positions of the first connecting frame and the second connecting frame correspond one-to-one. The modular debugging fixture also includes multiple locking components, which are sequentially connected to the first connecting frame and the second connecting frame to detachably connect the support rod and the subframe.

[0009] In some embodiments, the first connecting frame includes: a first connecting plate having a plurality of first connecting holes for a locking member to pass through, the ends of the first connecting plate being welded to the subframe; and two first connecting stiffeners having their bottom ends welded to the two ends of the top wall of the first connecting plate along the length direction, and the side walls of the two first connecting stiffeners being welded to the subframe.

[0010] In some embodiments, the second connecting frame includes: a second connecting plate having a plurality of second connecting holes for passing through locking components, the ends of the second connecting plate being welded to the support rod; and two second connecting stiffeners, the bottom ends of the two second connecting stiffeners being welded to the two ends of the bottom wall of the second connecting plate along the length direction, and the side walls of the two second connecting stiffeners being welded to the support rod.

[0011] In some implementations, the modular debugging fixture further includes: multiple sliders, each corresponding to the bottom end of the support rod, with a slot at the bottom end of the slider and a guide rail slidably inserted into the slot.

[0012] In some implementations, the distance between the two guide rails is adjustable, and the length of the connecting rod is adjustable.

[0013] In some embodiments, the subframe includes a main frame beam extending in a first horizontal direction and a vertical beam mounted at the end of the main frame beam and extending downward in a vertical direction. The modular debugging fixture also includes a second support frame, the second support frame being lower in height than the first support frame, the second support frame being slidably connected to the guide rail assembly, and the second support frame extending in a vertical direction and abutting against the bottom end of the vertical beam.

[0014] In some implementations, the modular debugging fixture also includes multiple protective pads, which are installed one-to-one on the top of multiple first support frames and second support frames and are used to protect the subframe.

[0015] In some implementations, the protective pad is made of polyurethane material.

[0016] The above technical solution provides a modular commissioning fixture for a pump truck. This fixture assists in the commissioning of the pump truck's undercarriage module, which includes a subframe and a pumping unit mounted on the subframe. The modular commissioning fixture includes a guide rail assembly and multiple first support frames. These first support frames are arranged parallel to each other along a first horizontal direction, with their bottom ends slidably connected to the guide rail assembly. The subframe extends along the first horizontal direction, and the top ends of the first support frames abut against the bottom ends of the subframe. All first support frames are detachably connected to the subframe. This structural design allows the subframe, pumping unit, main valve assembly, and distribution valve assembly to be modularly assembled on the assembly line. Directly placing them on the modular commissioning fixture effectively reduces the workload of disassembling and assembling hydraulic lines and electrical wiring harnesses, improving commissioning efficiency. Furthermore, the guide rail assembly design allows the first support frames to be adjusted in position according to actual needs, enhancing the flexibility and adaptability of the commissioning fixture.

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The modular debugging fixture for the pump truck according to this utility model is described below with reference to the accompanying drawings. Figure 1 The diagram shown illustrates an application scenario of the modular debugging fixture for a pump truck provided according to an embodiment of this utility model. Figure 2 As shown, Figure 1 A schematic diagram of component A. The modular debugging fixture provided in this embodiment of the invention is used to assist in the debugging of the pump truck unloading module. The pump truck unloading module includes a subframe 70 and a pumping unit 80, with the pumping unit 80 mounted on the subframe 70. The modular debugging fixture includes: Guide rail assembly 10 extends along a first horizontal direction; Multiple first support frames 20 are arranged in parallel and spaced along a first horizontal direction. The bottom ends of the multiple first support frames 20 are slidably connected to the guide rail assembly 10. The sub-frame 70 extends along the first horizontal direction. The top ends of the multiple first support frames 20 are used to abut against the bottom ends of the sub-frame 70. The multiple first support frames 20 are detachably connected to the sub-frame 70.

[0021] In the existing technology, during the commissioning of the pumping unit 80, it is necessary to adjust multiple parameters such as the venting of the main oil cylinder, the airtightness of the distribution mechanism, and the parallelism of the main oil cylinder. The commissioning process requires the disassembly and assembly of many hydraulic pipelines and electrical wiring harnesses, which is a large workload and inefficient.

[0022] The modular debugging fixture provided in this embodiment of the utility model mounts the pumping unit 80 onto the subframe 70. The subframe 70 is equipped with hydraulic components such as the main valve assembly 71 and the distribution valve assembly 72. Before debugging the pumping unit 80, the pumping unit 80, the main valve assembly 71, and the distribution valve assembly 72 can be assembled onto the subframe 70, and the hydraulic lines and electrical wiring harnesses can be connected. Debugging using these steps eliminates the need for repeated disassembly and reassembly of hydraulic and electrical lines, greatly reducing the workload and significantly improving debugging efficiency. Simultaneously, due to the guide rail assembly 10, the multiple first support frames 20 can be flexibly adjusted in position according to the actual size and shape of the subframe 70, ensuring that the first support frames 20 can stably support the subframe 70, enhancing the adaptability and flexibility of the debugging fixture. Furthermore, the detachable connection method makes the installation and disassembly process between the first support frames 20 and the subframe 70 more convenient, further improving the efficiency of the debugging work. The application of this modular commissioning fixture not only simplifies the commissioning process but also reduces commissioning costs, bringing great convenience to the production and maintenance of pump trucks.

[0023] In one embodiment, the guide rail assembly 10 includes two guide rail members 11 arranged parallel to each other along a second horizontal direction, which is perpendicular to the first horizontal direction. Each first support frame 20 includes a connecting rod and two support rods 21. The two support rods 21 extend vertically and are arranged parallel to each other. The bottom end of the support rods 21 is slidably connected to the guide rail member 11, and the connecting rod connects the two support rods 21. The design of the two support rods 21 makes the first support frame 20 structurally stable and able to withstand the weight of the subframe 70 and the pumping unit 80. At the same time, the setting of the connecting rod enhances the connection strength between the two support rods 21, preventing the support rods 21 from deforming or breaking during commissioning. The connecting rod connects the two support rods 21, enabling the two support rods 21 to move synchronously when sliding along the guide rail, ensuring the overall stability of the movement of the first support frame 20.

[0024] In one embodiment, the subframe 70 has first connecting frames 41 on both sides, and the support rod 21 has a second connecting frame 42 on its side wall. The positions of the first connecting frames 41 and the second connecting frames 42 correspond one-to-one. The modular debugging fixture also includes multiple locking components 31, which sequentially pass through the first connecting frames 41 and the second connecting frames 42 to detachably connect the support rod 21 and the subframe 70. Through the corresponding arrangement of the first connecting frames 41 and the second connecting frames 42, and the connecting action of the locking components 31, a firm connection between the support rod 21 and the subframe 70 is achieved. This connection method is not only simple in structure but also stable, maintaining the stability of the subframe 70 during debugging and avoiding debugging errors caused by shaking or displacement. The locking components 31 can be bolts, screws, pins, or other connecting components. Using the aforementioned locking components 31, quick locking or disassembly between the subframe 70 and the support rod 21 can be achieved, improving debugging efficiency. Meanwhile, the number and position of the locking parts 31 can be adjusted according to actual needs to meet the requirements of different subframe sizes and shapes, thus enhancing the versatility and flexibility of the debugging fixture.

[0025] In one embodiment, such as Figure 3-5 The figures shown are a front view, a side view, and a top view of the first connecting frame 41 provided according to an embodiment of the present invention. The first connecting frame 41 includes a first connecting plate 411 and two first connecting stiffeners 413. The first connecting plate 411 has multiple first connecting holes 412 for the locking member 31 to pass through. The end of the first connecting plate 411 is welded to the subframe 70. The bottom ends of the two first connecting stiffeners 413 are respectively welded to the two ends of the top wall of the first connecting plate 411 along the length direction. The side walls of the two first connecting stiffeners 413 are welded to the subframe 70. This structural design gives the first connecting frame 41 high strength and rigidity, enabling it to withstand large tensile and compressive forces, ensuring the reliability of the connection between the support rod 21 and the subframe 70. At the same time, the first connecting stiffeners 413 also enhance the connection stability between the first connecting plate 411 and the subframe 70, preventing loosening or breakage during debugging. In addition, the number and position of the first connecting holes 412 can be designed and adjusted according to actual needs, which improves the versatility and adaptability of the first connecting bracket 41.

[0026] In one embodiment, the second connecting frame 42 includes a second connecting plate (not shown) and two second connecting stiffeners (not shown). The second connecting plate has multiple second connecting holes for the locking components 31 to pass through. The ends of the second connecting plate are welded to the support rod 21. The bottom ends of the two second connecting stiffeners are welded to the two ends of the bottom wall of the second connecting plate along its length, and the side walls of the two second connecting stiffeners are welded to the support rod 21. The addition of the second connecting stiffeners not only enhances the connection strength between the second connecting plate and the support rod 21 but also improves the overall structure's resistance to deformation. This allows the support rod 21 to more stably support the subframe 70 during commissioning, reducing swaying or displacement caused by external forces. Simultaneously, the design of the second connecting holes provides more options for installing the locking components 31, allowing the number and position of the locking components 31 to be adjusted according to actual needs to meet the requirements of different commissioning scenarios. This modular design allows the commissioning fixture to exhibit greater flexibility and adaptability when dealing with subframes 70 of different sizes and shapes. In a specific embodiment, such as... Figure 2 As shown, the second connecting frame has the same structure as the first connecting frame and is arranged opposite to it. The second connecting plate is arranged opposite to the first connecting plate 411. The locking member 31 passes through the first connecting hole 412 and the second connecting hole to lock the first connecting plate 411 and the second connecting plate.

[0027] In one embodiment, the modular debugging fixture further includes multiple sliders 90, each corresponding to the bottom end of the support rod 21. Each slider 90 has a slot at its bottom, into which a guide rail is slidably inserted. The design of the sliders 90 makes the sliding of the support rod 21 on the guide rail smoother, reducing friction and wear, and improving the service life of the debugging fixture. Simultaneously, the size and shape of the slots can be customized according to the actual dimensions of the guide rail, ensuring a tight fit between the sliders 90 and the guide rail, preventing wobbling or detachment during sliding. This design not only improves the stability of the debugging fixture but also reduces maintenance costs, making the debugging process more efficient and reliable.

[0028] In one embodiment, the distance between the two guide rails 11 is adjustable, and the length of the connecting rod is also adjustable. Different models of pump trucks often have varying widths of the subframe 70. The adjustable distance between the two guide rails 11 allows this modular commissioning fixture to adapt to the commissioning needs of subframes 70 with different widths. In practical applications, simply adjusting the distance between the two guide rails 11 according to the actual width of the subframe 70 ensures that the first support frame 20 can accurately abut and lock against the subframe 70. Similarly, the adjustable length of the connecting rod further enhances the adaptability and flexibility of the commissioning fixture. When dealing with subframes 70 of different sizes and shapes, the structure and stability of the first support frame 20 can be optimized by adjusting the length of the connecting rod, thereby ensuring the accuracy and efficiency of the commissioning process.

[0029] In one embodiment, such as Figure 1 As shown, the subframe 70 includes a main frame beam extending along a first horizontal direction and a vertical beam installed at the end of the main frame beam and extending downwards in a vertical direction. The modular debugging fixture also includes a second support frame 50, the second support frame 50 being lower in height than the first support frame 20. The second support frame 50 is slidably connected to the guide rail assembly 10, and extends vertically, abutting against the bottom end of the vertical beam. The second support frame 50 provides additional support points for the vertical beam of the subframe 70, enhancing the stability of the subframe 70 during debugging. The addition of the second support frame 50 effectively distributes the pressure borne by the vertical beam, preventing deformation or damage to the vertical beam due to excessive pressure. Simultaneously, the sliding connection design between the second support frame 50 and the guide rail assembly 10 allows its position to be adjusted according to actual needs, adapting to the structural characteristics of different models of pump truck subframes 70.

[0030] In one embodiment, the modular debugging fixture further includes multiple protective pads 60, each corresponding to one of the tops of the multiple first support frames 20 and second support frames 50, for protecting the subframe 70. The installation of the protective pads 60 provides effective protection for the subframe 70. The protective pads 60 not only protect the paint on the subframe 70 but also effectively cushion the hard contact between the first support frames 20, second support frames 50, and the subframe 70, preventing surface damage to the subframe 70 due to collisions or friction.

[0031] In one embodiment, the protective pad 60 is made of polyurethane material. Polyurethane material has good elasticity and abrasion resistance, and can maintain stable performance during long-term use. The protective pad 60 made of this material can not only effectively absorb the impact force generated when the first support frame 20 comes into contact with the subframe 70, but also resist wear and tear during daily use, thus extending the service life of the protective pad 60.
