Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a brake pad holder for a rail vehicle braking system. Background Technology

[0002] In the early stages of rail vehicle development, braking systems were relatively simple, relying mainly on manual labor or simple mechanical devices. There was no concept of a dedicated brake pad holder, and the structure of braking components was very rudimentary. Typically, the brake pads were directly in contact with the wheels or other braking components, using friction to reduce vehicle speed. As the load capacity and operating speed of rail vehicles increased, this simple braking method gradually became insufficient to meet safety and performance requirements. With the advancement of the Industrial Revolution, significant progress in mechanical manufacturing technology provided technical support for the improvement of rail vehicle braking systems. People began to realize the need for more reliable braking components to ensure the safe operation of vehicles. Thus, some early prototypes of brake pad holders began to appear. These were typically composed of simple metal structures used to fix and support the brake pads, allowing the pads to make more stable contact with the wheels, thereby improving braking effectiveness.

[0003] However, for traditional equipment, the operation of traditional brake pad support is cumbersome and time-consuming when maintaining and replacing the excitation device. It requires the use of multiple tools and a lot of time for disassembly and installation, which not only increases the workload of maintenance personnel but also causes vehicles to be idle for extended periods, affecting transportation efficiency. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: a brake pad holder for a rail vehicle braking system, comprising a main body, a mounting frame and a mounting base fixedly installed at the rear end of the main body, a groove extending through the surface of the main body, an excitation device sleeved inside the groove, a rotating groove on the rear end surface of the main body, a placement groove on the inner surface of the groove, a fixing block sleeved inside the placement groove, a movable column fixedly installed at the rear end of the fixing block, a rack fixedly installed on the surface of the movable column, a gear fixedly installed inside the rotating groove, a rotating rod fixedly installed at the rear end of the gear, a gear fixedly installed at the other end of the rotating rod, a torsion spring sleeved inside the rotating groove, a rotating plate sleeved inside the rotating groove, an annular rack fixedly installed at the bottom end of the rotating plate, and a rotating lever fixedly installed at the top end of the rotating plate.

[0006] Preferably, the rotating block is semi-elliptical in shape, the groove is circular in shape, and both the groove and the excitation device are in two sets and symmetrically distributed on the surface of the main body. Here, the circular groove is adapted to the excitation device, facilitating installation and positioning.

[0007] Preferably, the top of the rotating groove is an arc-shaped, flat ellipse, the rotating block is fitted inside the rotating groove, the rotating plate is circular, and the fixing block is arc-shaped and fits tightly against the surface of the excitation device. Here, the arc-shaped, flat ellipse top of the rotating groove provides suitable rotation space and trajectory for the rotating block, making the rotation of the rotating block smoother.

[0008] Preferably, the torsion spring is initially in a semi-contracted state, with one end of the torsion spring fixedly connected to the inner surface of the rotating groove, and the other end of the torsion spring fixedly connected to the top of the rotating plate. Here, the torsion spring in the semi-contracted state has a certain preload, and when the rotating plate rotates, the torsion spring generates an elastic force.

[0009] Preferably, the surface of rack one meshes with the surface of gear one, and the surface of gear two meshes with the surface of the ring rack. There are four sets of gear one, rotating rod, gear two, and fixed block, arranged circumferentially within the rotating groove and placement groove. Here, the meshing of rack one with gear one and gear two with the ring rack achieves effective power transmission, allowing the rotation of the rotating plate to be accurately converted into the movement of the fixed block.

[0010] Preferably, the front surface of the main body has a first fixing groove, the inner surface of the first fixing groove has a second fixing groove, a spring is fitted inside the second fixing groove, and a fixing block is fitted inside both the first and second fixing grooves. Here, the first and second fixing grooves provide space for the installation and movement of the spring and the fixing block.

[0011] Preferably, one end of the spring is connected and fixed to the inner surface of the fixing groove two, and the other end of the spring is connected and fixed to the rear end surface of the fixing block. The springs are arranged in five sets in an array inside the fixing groove two. Here, the five sets of arrayed springs make the elastic force on the fixing block more uniform, enabling more stable expansion and contraction, enhancing the stability and reliability of the connection between the fixing block and other components, while also improving the buffering effect and reducing the impact force during the connection process.

[0012] Preferably, there are two sets of fixing slot one, symmetrically distributed at the front end of the main body, and two sets of fixing slot two, symmetrically distributed inside fixing slot one. The upper and lower ends of the fixing block are rounded. Here, the two sets of symmetrically distributed fixing slots one and two ensure more even force distribution when the brake pad support is connected to other components, improving the stability of the connection.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a main body, mounting frame, mounting base, groove, excitation device, rotating groove, placement groove, fixing block, moving column, rack and pinion, gear and rotating rod structure, multiple structures of the fixing block cooperate to move when the equipment is in use. When maintaining and replacing the excitation device, it can be replaced conveniently without the need for multiple tools and avoid spending a lot of time on disassembly and installation, effectively reducing the workload of maintenance personnel, avoiding long-term vehicle downtime, and effectively preventing the impact on transportation efficiency.

[0015] 2. In this utility model, by setting a fixed groove one, a fixed groove two, a spring, and a fixed plug structure, when the equipment is in use, the combination of the spring and the fixed plug can be used to connect and fix with other components. The elasticity of the spring allows the fixed plug to extend and retract within a certain range, which is convenient for installation and disassembly. At the same time, it can also play a buffering and tightening role in the connection process, ensuring the stability and reliability of the connection between the brake pad support and other components.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model provides a technical solution: a brake pad holder for a rail vehicle braking system, comprising a main body 1, a mounting bracket 2 and a mounting base 3 fixedly mounted at the rear end of the main body 1, a groove 4 extending through the surface of the main body 1, an excitation device 5 fitted inside the groove 4, a rotating groove 6 on the rear end surface of the main body 1, a placement groove 7 on the inner surface of the groove 4, a fixing block 8 fitted inside the placement groove 7, a moving column 9 fixedly mounted at the rear end of the fixing block 8, a rack 10 fixedly mounted on the surface of the moving column 9, a gear 11 fitted inside the rotating groove 6, a rotating rod 12 fixedly mounted at the rear end of the gear 11, a gear 13 fixedly mounted at the other end of the rotating rod 12, a torsion spring 14 fitted inside the rotating groove 6, a rotating plate 15 fitted inside the rotating groove 6, an annular rack 16 fixedly mounted at the bottom end of the rotating plate 15, and a rotating lever fixedly mounted at the top end of the rotating plate 15. When it is necessary to replace or fix the excitation device 5, firstly, the hand contacts the surface of the rotating block 17, then rotates the rotating block 17. The rotation of the rotating block 17 drives the rotating plate 15 to rotate, then the rotation of the rotating plate 15 drives the torsion spring 14 to a compressed state, then the rotation of the rotating plate 15 drives the ring rack 16 to rotate, then the rotation of the ring rack 16 drives the gear 13 to rotate, then the rotation of the gear 13 drives the rotating rod 12 to rotate, then the rotation of the rotating rod 12 drives the gear 11 to rotate, then the rotation of the gear 11 drives the rack 10 to move, then the movement of the rack 10 drives the movement column 9 to move, then the movement of the movement column 9 drives the fixing block 8 to move, and finally the fixing block 8 moves away from the surface of the excitation device 5, so that the excitation device 5 can be replaced or maintained.

[0027] Please see Figures 1-5The rotating lever 17 is semi-elliptical in shape, the groove 4 is circular in shape, and there are two sets of grooves 4 and excitation devices 5, which are symmetrically distributed on the surface of the main body 1. The top of the rotating groove 6 is arc-shaped flat elliptical, and the rotating lever 17 is fitted inside the rotating groove 6. The rotating plate 15 is circular in shape, and the fixing block 8 is arc-shaped and fits tightly against the surface of the excitation device 5. The torsion spring 14 is initially in a semi-contracted state. One end of the torsion spring 14 is connected and fixed to the inner surface of the rotating groove 6, and the other end of the torsion spring 14 is connected and fixed to the top of the rotating plate 15. The surface of rack 10 meshes with the surface of gear 11, and the surface of gear 13 meshes with the surface of the ring rack 16. Gear 11 and rotating rod 1 2. There are four sets of gear 213 and fixing blocks 8, which are circumferentially distributed inside the rotating groove 6 and the placement groove 7. One end of the spring 20 is connected and fixed to the inner surface of the fixing groove 21, and the other end of the spring 20 is connected and fixed to the rear end surface of the fixing block 21. There are five sets of spring 20, which are arrayed inside the fixing groove 21. There are two sets of fixing groove 18, which are symmetrically distributed at the front end of the main body 1. There are two sets of fixing groove 29, which are symmetrically distributed inside the fixing groove 18. The upper and lower ends of the fixing block 21 are rounded. The rounded corner design of the upper and lower ends of the fixing block 21 makes it easy for the fixing block 21 to be inserted into and pulled out of the connection holes of other components, reducing the difficulty of installation and disassembly and improving the convenience of operation.

[0028] Example 2

[0029] Please see Figure 4 The front surface of the main body 1 has a fixing groove 18, and the inner surface of the fixing groove 18 has a fixing groove 19. A spring 20 is fitted inside the fixing groove 19. Fixing blocks 21 are fitted inside the fixing grooves 18 and 19. When the fixing structure at the front of the main body 1 is needed, first align the other components connected to the brake pad support with the fixing groove 18 at the front of the main body 1, then insert the other components into the fixing groove 18. Then, the surface of the other components contacts the surface of the fixing block 21, and then the fixing block 21 is pressed. The fixing block 21 then presses the spring 20, and the spring 20 is compressed and deformed by the compression of the fixing block 21. When the other components are inserted into the appropriate position, the elastic force of the spring 20 will make the fixing block 21 press tightly against the other components, thereby achieving a firm connection between the brake pad support and other components.

[0030] Working principle: When it is necessary to replace or fix the excitation device 5, firstly, the hand contacts the surface of the rotating block 17, then rotates the rotating block 17. The rotation of the rotating block 17 drives the rotating plate 15 to rotate, which in turn drives the torsion spring 14 to a compressed state. Subsequently, the rotation of the rotating plate 15 drives the ring rack 16 to rotate, which in turn drives the gear 13 to rotate. The rotation of the gear 13 then drives the rotating rod 12 to rotate, which in turn drives the gear 11 to rotate. The rotation of the gear 11 then drives the rack 10 to move, and so on. The movement of the 10-bar linkage drives the movement of the 9-bar linkage, which in turn drives the movement of the 8-bar linkage. The 8-bar linkage then disengages from the surface of the excitation device 5, allowing for replacement or maintenance of the excitation device 5. When the fixing structure at the front end of the main body 1 is needed, first align the other components connected to the brake pad support with the fixing groove 18 at the front end of the main body 1. Then, insert the other components into the fixing groove 18, bringing their surfaces into contact with the surface of the fixing block 21. The fixing block 21 is then pressed, compressing the spring 20. The spring 20 is then compressed and deformed by the pressure of the fixing block 21. When the other components are inserted into the appropriate position, the elastic force of the spring 20 causes the fixing block 21 to press firmly against the other components, thus achieving a secure connection between the brake pad support and other components.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
