Description

Technical Field

[0001] This invention belongs to the field of vehicle braking technology, and more specifically, relates to a base plate assembly integrating a 120 valve control module. Background Technology

[0002] The railway vehicle braking system is a core component ensuring train operation safety, and its performance directly affects the train's operational stability, braking efficiency, and the safety of passengers' lives and property. In the railway vehicle braking system, the air cylinder, as a key device for storing compressed air, provides the power source for the braking actuator; the I20 valve, as the main brake control valve, controls the on / off state and pressure regulation of compressed air to achieve the core functions of braking and releasing the train. Together with other braking components, these two systems form the power transmission and control center for train braking.

[0003] Currently, components such as the 120 valve, multiple air cylinders, and pressure relief valve need to be installed on the vehicle. However, the installation methods are relatively scattered, and these components require individual positioning and fixation, resulting in a loose overall structure of the braking system and complex connections between components. Furthermore, the piping connections between these components are disorganized and tortuous, increasing airflow resistance and pressure loss during compressed air transmission. Additionally, the stability of the fixed installation of these components is insufficient, making them prone to displacement and posing potential safety hazards to railway vehicles. Summary of the Invention

[0004] The purpose of this invention is to provide a base plate assembly that integrates a 120 valve control module, so as to solve the technical problems of multiple components being installed in a scattered and disorganized manner, and the lack of installation stability in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a baseboard assembly integrating a 120 valve control module, comprising:

[0006] The support plate has a first mounting area, a second mounting area, a third mounting area, and a fourth mounting area located on the same end face and respectively used for mounting a 120 valve, a double-chamber air cylinder, an auxiliary air cylinder, and a pressure relief valve; the first mounting area and the fourth mounting area are each provided with fixing holes; the second mounting area and the third mounting area are each provided with a fixing plate and clearance holes arranged around the fixing plate, and the fixing plate is provided with fixing holes;

[0007] Multiple mounting structures are respectively disposed at both ends of the support plate and extend outward in a direction away from the support plate; each mounting structure has a bent portion forming a cavity, and the mounting structure is provided with fixing holes passing through the bent portion and the cavity for fixed connection with the bottom of the vehicle;

[0008] Fasteners, in multiple quantities, are respectively inserted into multiple fixing holes for fixing the 120 valve, dual-chamber air cylinder, auxiliary air cylinder, and pressure relief valve to the bearing plate, and for fixing the mounting structure to the vehicle.

[0009] In one possible implementation, the mounting structure is integrally formed with the support plate, and the end faces of the support plate and the mounting structure away from the first mounting area are recessed toward the first mounting area to form a plurality of elongated bent portions.

[0010] In one possible implementation, there are four mounting structures, arranged in pairs; the two mounting structures in the same group are symmetrically arranged on both sides of the support plate, and there are two bending portions that penetrate the support plate and the mounting structure.

[0011] In one possible implementation, the second mounting area includes a plurality of the clearance holes, and the plurality of clearance holes are located on both sides of one of the bends; the third mounting area includes a plurality of the clearance holes, and the plurality of clearance holes are located on both sides of another bend.

[0012] In one possible implementation, the mounting structure further includes a pad located within the cavity and an elastic pad mounted on the pad. The lower end face of the pad is flush with the lower end face of the bearing plate. The pad has a mounting hole, and the elastic pad has a positioning shaft passing through the mounting hole. The positioning shaft has a connecting hole coaxially arranged with the fixing hole, and the fastener passes through the fixing hole and the connecting hole.

[0013] In one possible implementation, the fastener includes a bolt, a nut, and a limiting block. The bolt passes through the fixing hole and the communicating hole and is locked in place by the nut. The bolt has a limiting hole located below the nut, and the limiting block is installed in conjunction with the limiting hole, with the upper end face of the limiting block abutting against the lower end face of the nut.

[0014] In one possible implementation, the clearance hole is a U-shaped hole arranged around the fixing plate, and the fixing hole on the fixing plate is an elongated hole.

[0015] In one possible implementation, the base plate assembly integrating the 120 valve control module further includes:

[0016] There are multiple mounting blocks, arranged in pairs; the two mounting blocks in the same group are used to fix the vehicle and the load-bearing plate respectively, and the mounting blocks are provided with connecting ends;

[0017] Multiple cables are installed between two mounting blocks in the same group, and both ends are fixedly connected to the two connecting ends respectively.

[0018] In one possible implementation, the base plate assembly of the integrated 120 valve control module further includes several support members, each of which has a U-shaped structure and is fixedly connected to the bearing plate at both ends. An installation cavity for accommodating the dual-chamber air cylinder and the auxiliary air cylinder is formed between the support members and the bearing plate, and the outer sides of the dual-chamber air cylinder and the auxiliary air cylinder are supported on the support members.

[0019] In one possible implementation, the base plate assembly of the integrated 120 valve control module further includes two support beams fixedly installed on the bottom of the vehicle, the two support beams being arranged in parallel and spaced apart; the bearing plate is located between the two support beams, and each support beam has a misalignment groove on the side near the bearing plate, the mounting structure passing through the misalignment groove and connecting to the support beam.

[0020] The beneficial effects of the integrated 120 valve control module base plate assembly provided by this invention are as follows: Compared with the prior art, the integrated 120 valve control module base plate assembly of this invention, during operation, first determines the mounting reference of the support plate according to the space of the vehicle chassis, and pre-installs the 120 valve and pressure relief valve on the first and fourth mounting areas of the support plate respectively, and fixes them with fasteners passing through the fixing holes. The dual-chamber air cylinder and auxiliary air cylinder are installed in the second and third mounting areas respectively, and the mounting points on the dual-chamber air cylinder and auxiliary air cylinder pass through the clearance holes to stably connect with the fixing plate, and are fixed with fasteners, realizing a compact installation mode of multiple components integration. Then, the support plate, 120 valve, dual-chamber air cylinder, auxiliary air cylinder, and pressure relief valve are moved as a whole to the bottom of the vehicle chassis, and the multiple mounting structures are connected with the mounting positions of the vehicle chassis. With the help of the bending part and cavity, a structure with a certain degree of elasticity is formed, so that the fasteners pass through the fixing holes and are firmly and securely fixed to the vehicle chassis, improving the connection reliability. In this way, by integrating components into a modular assembly using a support plate, the degree of integration is improved, meeting the requirements for vehicle compactness. Furthermore, the multiple mounting areas of the support plate ensure a neat component layout, shortening brake line length and optimizing routing, reducing airflow resistance and pressure loss. The support plate also secures the components to the mounting structure, avoiding deviations that can occur with individual component fixings, while the hollow sections at bends buffer vibration and impact, significantly improving installation stability.

[0035] Please see Figures 1 to 7The base plate assembly of the integrated 120 valve control module provided by the present invention will now be described. An integrated 120 valve control module base plate assembly includes a support plate 10, a mounting structure 20, and fasteners 30. The support plate 10 has a first mounting area 11, a second mounting area 12, a third mounting area 13, and a fourth mounting area 14 located on the same end face and respectively used for mounting a 120 valve 70, a dual-chamber air cylinder 71, a secondary air cylinder 72, and a pressure relief valve 73. Fixing holes 15 are provided on both the first mounting area 11 and the fourth mounting area 14. Fixing plates 16 and clearance holes 17 arranged around the fixing plates 16 are provided on both the second mounting area 12 and the third mounting area 13. The fixing plates 16 have... The mounting structure 20 has multiple mounting holes 15; it is located at both ends of the support plate 10 and extends outward in a direction away from the support plate 10; the mounting structure 20 has a bent portion 22 forming a cavity 21, and the mounting structure 20 has mounting holes 15 that pass through the bent portion 22 and the cavity 21 and are used for fixed connection with the bottom of the vehicle; the fasteners 30 have multiple fasteners that pass through the multiple mounting holes 15 and are used for fixed connection of valve 70, double chamber air cylinder 71, auxiliary air cylinder 72, and pressure relief valve 73 to the support plate 10 and for fixed connection of mounting structure 20 to the vehicle.

[0036] The base plate assembly of the integrated 120 valve control module provided by this invention, compared with the prior art, uses a support plate 10 as the integration carrier. It achieves precise positioning of the 120 valve, dual-chamber air cylinder 71, auxiliary air cylinder 72, and pressure relief valve 73 by dividing the assembly into first mounting areas 11 to fourth mounting areas 14. The fixing holes 15 in the first mounting area 11 and fourth mounting area 14 are adapted to the mounting interfaces of the 120 valve and pressure relief valve 73. The fixing plates 16 and clearance holes 17 in the second and third mounting areas 13 are for the dual-chamber air cylinder 71. The auxiliary air cylinder 72 provides stable support, and the clearance hole 17 can avoid interference between the bottom structure of the air cylinder and the support plate 10, ensuring that the components fit and are fixed. The mounting structure 20 forms a cavity 21 through the outward-extending bending parts 22 at both ends, which not only enhances its own structural strength, but also makes it securely installed with the vehicle chassis by means of the elasticity of the bending parts 22, realizing a stable connection between the chassis assembly and the vehicle. The fasteners 30, through the fixing holes 15, respectively complete the double fixing of the braking components to the support plate 10 and the support plate 10 to the vehicle, thus constructing a complete integrated installation system.

[0037] During operation, the installation reference of the support plate 10 is first determined according to the space of the vehicle chassis. The 120 valve 70 and the pressure relief valve 73 are pre-installed on the first installation area 11 and the fourth installation area 14 of the support plate 10, respectively, and fixed with fasteners 30 passing through the fixing holes 15. The dual-chamber air cylinder 71 and the auxiliary air cylinder 72 are installed on the second installation area 12 and the third installation area 13, respectively, and the mounting points on the dual-chamber air cylinder 71 and the auxiliary air cylinder 72 are made to pass through the clearance holes 17 and be stably connected to the fixing plate 16, and fixed with fasteners 30, realizing a compact installation mode of multiple components integration. Then, the support plate 10, the 120 valve 70, the dual-chamber air cylinder 71, the auxiliary air cylinder 72, and the pressure relief valve 73 are moved as a whole to the bottom of the vehicle chassis, and the multiple mounting structures 20 are connected to the mounting positions of the vehicle chassis. With the help of the bending part 22 and the cavity 21, a structure with a certain degree of elasticity is formed, so that the fasteners 30 pass through the fixing holes 15 and are firmly and securely fixed to the vehicle chassis, improving the connection reliability. In this way, by integrating the distributed components into a modular assembly using the support plate 10, the degree of integration is improved, meeting the requirements of vehicle compactness. Furthermore, the multiple mounting areas of the support plate 10 ensure a neat component layout, shortening the length of the brake lines and optimizing their routing, reducing airflow resistance and pressure loss. Moreover, the support plate 10 is fixed to the mounting structure 20, avoiding deviations caused by individual component fixing, while the cavity 21 of the bent portion 22 buffers vibration and impact, significantly improving installation stability.

[0038] Please see Figures 1 to 3 , Figures 5 to 7 In one specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the mounting structure 20 and the support plate 10 are integrally formed. The end faces of the support plate 10 and the mounting structure 20 away from the first mounting area 11 are recessed towards the first mounting area 11 to form multiple elongated bent portions 22. The mounting structure 20 and the support plate 10 are manufactured using an integral molding process, with no splicing gaps, forming a complete rigid structure. Specifically, the end faces of the support plate 10 and the mounting structure 20 away from the first mounting area 11 are recessed towards the first mounting area 11, thereby forming multiple elongated bent portions 22. The space enclosed by the bent portions 22 constitutes a buffer cavity 21. The one-piece molding avoids the welding stress or bolt 31 loosening risks of traditional split connections, greatly improving the overall structural strength and rigidity, and ensuring that the bearing plate 10 is not easily deformed when bearing the weight of components such as the air cylinder and 120 valve and the vibration load of the train; the long strip-shaped bending part 22 is formed by concave molding, which not only uses the principle of structural mechanics to enhance the impact resistance of the installation structure 20, but also provides a buffer space for vibration energy through the cavity structure 21, making the force on the bearing plate 10 more uniform and further ensuring the installation stability of the braking components.

[0039] Please see Figures 1 to 3 , Figure 6 and Figure 7As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, there are four mounting structures 20, arranged in pairs. The two mounting structures 20 in the same group are symmetrically arranged on both sides of the support plate 10. There are two bending portions 22, which penetrate the support plate 10 and the mounting structure 20. The symmetrical distribution forms a balanced force distribution layout. The two bending portions 22 penetrate the support plate 10 and the mounting structure 20, making the two form a continuous rigid whole. The symmetrically arranged mounting structures 20 can evenly distribute the weight of the braking components and the train vibration load to both sides of the support plate 10, avoiding structural deformation caused by concentrated force on one side. The through bending portions 22 enhance the connection strength between the support plate 10 and the mounting structure 20 through the integrated structure, improve the overall torsional resistance, and effectively resist the alternating impact during train operation. The four mounting points, combined with the symmetrical layout, greatly improve the connection stability between the base plate assembly and the bottom of the vehicle and reduce installation deviation.

[0040] Please see Figures 1 to 3 , Figure 6 and Figure 7 As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the second mounting area 12 includes multiple clearance holes 17, which are located on both sides of a bend 22; the third mounting area 13 includes multiple clearance holes 17, which are located on both sides of another bend 22. The second mounting area 12 and the third mounting area 13 are used to mount the dual-chamber air cylinder 71 and the auxiliary air cylinder 72. The arrangement of multiple clearance holes 17 and multiple fixing plates 16 increases the number of fixing points for the dual-chamber air cylinder 71 and the auxiliary air cylinder 72, ensuring a stable and reliable connection between the dual-chamber air cylinder 71 and the auxiliary air cylinder 72 and the support plate 10. The bend 22 serves as a rigid reinforcement structure for the support plate 10, and the layout of the clearance holes 17 on both sides ensures that the air cylinder mounting area corresponds to the mechanical reinforcement area of ​​the support plate 10. This structure enhances the structural strength of the air cylinder mounting area and improves the reliability of fixing the dual-chamber air cylinder 71 and the auxiliary air cylinder 72.

[0041] Please see Figure 4 and Figure 5As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the mounting structure 20 is further provided with a pad 23 located in the cavity 21 and an elastic pad 24 mounted on the pad 23. The lower end face of the pad 23 is flush with the lower end face of the support plate 10. The pad 23 has a mounting hole 25, and the elastic pad 24 has a positioning shaft 26 passing through the mounting hole 25. The positioning shaft 26 has a connecting hole 27 arranged coaxially with the fixing hole 15. The fastener 30 passes through the fixing hole 15 and the connecting hole 27. The addition of the pad 23 and the elastic pad 24 in the cavity 21 of the mounting structure 20, with the lower end face of the pad 23 flush with the lower end face of the support plate 10, ensures that the mounting surface is flat. Mounting holes 25 are provided in the pad 23. The positioning shaft 26 of the elastic pad 24 passes through the mounting holes 25 for precise positioning. The connecting hole 27 on the positioning shaft 26 is coaxial with the fixing hole 15 of the mounting structure 20. The fastener 30 passes through the fixing hole 15 and the connecting hole 27 in sequence to complete the connection. The elastic pad 24 can buffer the vibration and impact generated by the train operation through its own deformation, reduce the impact of alternating loads on the fastener 30, and prevent the bolt 31 from loosening. The cooperation between the positioning shaft 26 and the mounting hole 25 ensures the coaxiality of the elastic pad 24, the pad 23, and the mounting structure 20, improving the installation accuracy. The pad 23 enhances the local support strength of the mounting structure 20 and prevents deformation of the cavity 21 area under stress. The flush lower end face ensures that the base plate assembly fits tightly with the bottom of the vehicle, avoiding swaying caused by gaps. The overall structure, through the combination of rigid support and elastic buffering, greatly improves the installation stability, reduces the risk of component displacement, adapts to the high requirements of the braking system for vibration resistance, and extends the service life of the equipment.

[0042] Please see Figure 5 As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the fastener 30 includes a bolt 31, a nut 32, and a limiting block 33. The bolt 31 passes through the fixing hole 15 and the connecting hole 27, and is locked and fixed by the nut 32. A limiting hole is provided on the bolt 31 located below the nut 32, and the limiting block 33 is installed in conjunction with the limiting hole, with the upper end face of the limiting block 33 abutting against the lower end face of the nut 32. The fastener 30 adopts a combination structure of bolt 31, nut 32, and limiting block 33. The bolt 31 passes through the fixing hole 15 and the connecting hole 27 to form a basic connection, and the tightening of the nut 32 achieves initial locking and fixing. The limiting hole on the bolt 31 is installed in conjunction with the limiting block 33, and the upper end face of the limiting block 33 tightly abuts against the lower end face of the nut 32 to form double fixing. In this way, the nut 32 can be effectively prevented from loosening due to train running vibration. The multiple fixing structure greatly improves the connection reliability and avoids the problem of easy loosening of the traditional single bolt 31 connection.

[0043] Please see Figures 1 to 3 , Figure 6 and Figure 7In one specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the clearance hole 17 is a U-shaped hole arranged around the fixing plate 16, and the fixing hole 15 on the fixing plate 16 is an elongated hole. The U-shaped holes distributed around the fixing plate 16 provide sufficient installation space for the connection structure at the bottom of components such as the dual-chamber air cylinder 71 and the auxiliary air cylinder 72, so that the connection structure passes through the clearance hole 17 and is located below the fixing plate 16, so that the connection structure and the fixing plate 16 can be accurately connected. The elongated hole on the fixing plate 16 serves as the fixing hole 15, ensuring that components such as the air cylinder can be accurately fitted and fixed to the fixing plate 16.

[0044] Please see Figure 6 As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the base plate assembly of the integrated 120 valve control module further includes multiple mounting blocks 40 and multiple cables 42. The multiple mounting blocks 40 are arranged in pairs, and the two mounting blocks 40 in the same group are respectively used to fix them on the vehicle and the support plate 10, and the mounting blocks 40 are provided with connecting ends 41. The multiple cables 42 are respectively installed between the two mounting blocks 40 in the same group, and their two ends are respectively fixedly connected to the two connecting ends 41. The integrated base plate assembly adds multiple mounting blocks 40 and cables 42 to form an auxiliary stabilizing structure. The mounting blocks 40 are arranged in pairs, one mounting block 40 in the same group is fixed to the bottom of the vehicle, and the other mounting block 40 is correspondingly fixed to the support plate 10. Each mounting block 40 is provided with a connecting end 41. The two ends of the cables 42 are respectively fixed to the connecting ends 41 of the two mounting blocks 40 in the same group, forming a tension connection bridging the vehicle and the support plate 10. The preload of the cable 42 provides additional constraint to the bearing plate 10, forming a dual fixing system with the mounting structure 20 on the bearing plate 10. The cable 42 can disperse the vibration load borne by the bearing plate 10, balance the torque generated by the gravity of the braking components, and reduce stress concentration in the main mounting structure 20. Under the bumpy and impact conditions of train operation, the cable 42 can buffer vibration energy through elastic deformation, suppress high-frequency shaking of the bearing plate 10, and reduce the risk of component displacement. At the same time, the grouped cable 42 can adjust its tension according to the actual force requirements, adapt to dynamic conditions under different loads and speeds, and enhance the overall reliability of the connection between the braking system and the vehicle.

[0045] Please see Figure 6As a specific embodiment of the base plate assembly of the integrated 120 valve control module provided by the present invention, the base plate assembly of the integrated 120 valve control module further includes several support members 50. The support members 50 have a U-shaped structure, and both ends are fixedly connected to the support plate 10. A mounting cavity 51 for accommodating the dual-chamber air cylinder 71 and the auxiliary air cylinder 72 is formed between the support members 50 and the support plate 10, and the outer sides of the dual-chamber air cylinder 71 and the auxiliary air cylinder 72 are supported on the support members 50. The support members 50 and the support plate 10 enclose the mounting cavity 51 adapted to the shape of the dual-chamber air cylinder 71 and the auxiliary air cylinder 72, and the outer walls of the dual-chamber air cylinder 71 and the auxiliary air cylinder 72 are tightly fitted with the inner wall of the support members 50 to achieve support and fixation. In this configuration, the U-shaped support 50 provides lateral restraint to the double-chamber air cylinder 71 and the auxiliary air cylinder 72 through its side walls. Combined with the bottom support of the bearing plate 10, this creates a three-dimensional fixed structure, significantly increasing the contact area between the double-chamber air cylinder 71 and the auxiliary air cylinder 72 and the base plate, thus dispersing the pressure generated by the self-weight and vibration load of the double-chamber air cylinder 71 and the auxiliary air cylinder 72. Simultaneously, the U-shaped structure itself has excellent elastic deformation capacity, which can buffer some vibration energy and reduce the rigid impact between the double-chamber air cylinder 71 and the auxiliary air cylinder 72 and the bearing plate 10.

[0046] Please see Figure 1 and Figure 7 The base plate assembly integrating the 120 valve control module also includes two support beams 60 fixedly mounted on the bottom of the vehicle, arranged in parallel and spaced apart. A support plate 10 is located between the two support beams 60, and each support beam 60 has a misalignment groove 61 on the side closest to the support plate 10. The mounting structure 20 passes through the misalignment groove 61 and connects to the support beam 60. The two support beams 60 are pre-fixed on the vehicle chassis, forming a stable load-bearing foundation. The support plate 10 is fitted between the two support beams 60, and the support beam 60 has a misalignment groove 61 on the side closest to the support plate 10. The mounting structure 20 passes through the misalignment groove 61 to achieve a rigid connection with the support beam 60. A transitional support structure between the vehicle and the chassis 10 is constructed using support beams 60. The parallel, spaced support beams 60 distribute the weight load of the braking components, enhancing the overall mounting structure 20's resistance to deformation. The mounting structure 20 passes through the misalignment groove 61 from bottom to top and then shifts laterally to one side, allowing it to be stably supported on the support beams 60, where it is then secured using fasteners 30. This connection method strengthens the connection between the chassis 10 and the vehicle frame, reduces component sway, and improves the stability of the braking system.
