Description

Technical Field

[0001] This application belongs to the field of brake cylinder technology, and in particular relates to a brake cylinder head press-fitting device. Background Technology

[0002] The braking system of railway vehicles is equipped with a brake cylinder, which converts compressed air into thrust. This thrust is amplified by components such as levers, rods, and brake beams, and then applied to the brake shoes, causing friction between the brake shoes and the wheels, thereby braking the railway freight cars. The brake cylinder mainly consists of a cylinder body, piston, piston rod, release spring, and front cover. The piston and piston rod are riveted together as a whole, and the release spring is located between the piston and the front cover.

[0003] During brake cylinder assembly, the release spring needs to be compressed to press the front cover onto the machine. Typically, the release spring can be compressed manually to assemble the front cover, but this is labor-intensive and carries the risk of injury from spring breakage. Alternatively, a press assembly line can be used to assemble the front cover, but this is costly and only suitable for mass production. Utility Model Content

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0041] This application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Inside the cylinder of a railway vehicle braking system, a spring is compressed between the piston and the cylinder head. During assembly, the spring must first be fitted onto the piston rod, and then the cylinder head is pushed and positioned onto the cylinder body to align the cylinder body flange and the cylinder head flange, which is then locked in place with fasteners. However, during the cylinder head's positioning, the spring is compressed, creating a certain elastic reaction force between the cylinder body and the cylinder head. This force increases as the cylinder head is positioned, making the alignment of the cylinder head and cylinder body difficult and inefficient, and posing a risk of spring bounce, which could threaten personnel safety.

[0043] Therefore, this application provides a brake cylinder head press-fitting device and method, which aims to improve the convenience and safety of cylinder head installation and operation to a certain extent, and reduce equipment size and cost.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments, the brake cylinder head pressing device is configured as a composite device integrating clamping and positioning functions and pushing and pressing functions, so as to conveniently realize the positioning and fixing of the brake cylinder and the pushing and pressing operation, and reduce the complexity and scale of the device structure to a certain extent, and also improve operational safety and efficiency.

[0045] Specifically, the brake cylinder head pressing device includes a support mechanism 1, a clamping mechanism 2, and a pressing mechanism 3. The clamping mechanism 2 and the pressing mechanism 3 are mounted on the support mechanism 1. Based on the support mechanism 1, the clamping operation of the cylinder body 41 of the brake cylinder 4 and the pressing operation of the cylinder head 42 of the brake cylinder 4 are performed. When the brake cylinder head pressing device is working, the support mechanism 1 can be stably placed on the site foundation. Then, the clamping mechanism 2 clamps the cylinder body 41 of the brake cylinder 4 to fix the cylinder body 41. Then, the pressing mechanism 3 pushes the cylinder head 42 of the brake cylinder 4 towards the cylinder body 41, and finally achieves stable abutment between the cylinder head 42 and the cylinder body 41, which is then locked with fasteners.

[0046] The support mechanism 1 includes a support 11 and a support column 12, with the support column 12 mounted on the support 11. The support 11 serves as a load-bearing foundation and can be placed on a site foundation to maintain the stability of the brake cylinder head pressing device. The support column 12 serves as a supporting mounting foundation for the clamping mechanism 2 and / or the pressing mechanism 3, and is used to support and fix the clamping mechanism 2 and / or the pressing mechanism 3.

[0047] The clamping mechanism 2 adopts the principle of opening and closing clamping by the approach and distance of the clamping members, which is used to adapt to cylinder structures of different specifications and has good adaptability. The clamping mechanism 2 specifically includes a first clamping member 21, a second clamping member 22, and a clamping drive cylinder 23. The first clamping member 21 and the second clamping member 22 are mounted on the support column 12. The cylinder bottom 232 and the cylinder rod 231 of the clamping drive cylinder 23 are respectively connected to the first clamping member 21 and the second clamping member 22.

[0048] Specifically, one or both of the first clamping member 21 and the second clamping member 22 are rotatably mounted on the support column 12. This allows the first clamping member 21 and the second clamping member 22 to rotate relative to the support column 12, moving closer or further apart, thereby achieving clamping and releasing operations. In other words, at least one of the first clamping member 21 and the second clamping member 22 is a rotatable component, thus possessing the ability to clamp and release the cylinder 41.

[0049] The clamping drive cylinder 23 is a power element for clamping and releasing operations. The cylinder rod 231 and cylinder bottom 232 of the clamping drive cylinder 23 are rotatably connected to the first clamping member 21 and the second clamping member 22, respectively. That is, one of the cylinder rod 231 and cylinder bottom 232 is rotatably connected to the first clamping member 21 and the other is rotatably connected to the second clamping member 22. Thus, by controlling the extension and retraction of the clamping drive cylinder 23, the first clamping member 21 and / or the second clamping member 22 can be pulled to deflect relative to the support column 12, so as to adjust the included angle and distance between the first clamping member 21 and the second clamping member 22, thereby realizing the clamping and releasing function of the clamping mechanism 2.

[0050] In order to achieve stable clamping, the first clamping member 21 is provided with a first clamping part 211a, and the second clamping member 22 is provided with a second clamping part 221a. The first clamping part 211a and the second clamping part 221a can be matched and arranged opposite to each other. So when the clamping drive cylinder 23 is activated, the first clamping part 211a and the second clamping part 221a can approach or move away from each other to directly contact the cylinder body 41 of the brake cylinder 4 or release the cylinder body 41 of the brake cylinder 4.

[0051] The pressing mechanism 3 is used to push the cylinder head 42 of the brake cylinder 4, bringing it close to and stably positioning it onto the cylinder body 41 of the brake cylinder 4. For this purpose, the pressing mechanism 3 may include a pressing member 31 and a pressing drive cylinder 32. The pressing drive cylinder 32 is connected to the support 11, and the cylinder rod of the pressing drive cylinder 32 is connected to the pressing member 31. Thus, by controlling the action of the pressing drive cylinder 32, the pressing member 31 can be moved to push the cylinder head 42 of the brake cylinder 4 towards the cylinder body 41.

[0052] Generally, the shape and structure of the pressing member 31 can be matched with the cylinder head 42 of the brake cylinder 4, so that the pressing member 31 can stably push the cylinder head 42. Considering that the cylinder head 42 will have an opening for the piston rod 43 of the brake cylinder 4 to pass through, the pressing member 31 can also be provided with a positioning hole 311 for fitting onto the piston rod 43. The piston rod 43 is used to achieve the matching and alignment of the pressing member 31 and the cylinder head 42, which greatly simplifies the contact and positioning operation between the two, improves the positioning efficiency and stability, and can also simplify the positioning structure to a certain extent. This helps to reduce the overall structural scale of the pressing device and facilitates flexible use.

[0053] See Figure 1 In some embodiments, the support 11 can be configured as a plate-shaped component with a certain supporting area, thereby stably maintaining the overall posture stability of the support mechanism 1.

[0054] The support column 12 can be placed upright on the support 11, and the support column 12 can be orthogonal to the plate of the support 11.

[0055] To facilitate the movement of the support mechanism 1, a hoisting hole 121 or other hoisting and cooperating structure can be provided on the support column 12 to facilitate the hoisting and movement of the pressing device.

[0056] See Figure 1 and Figure 2 In some embodiments, considering that the clamping drive cylinder 23 is movably connected to the first clamping member 21 and the second clamping member 22, and that the movement patterns of the clamping drive cylinder 23 and the first clamping member 21 and the second clamping member 22 are completely different, when the first clamping member 21 and the second clamping member 22 deflect to a certain angle, the clamping drive cylinder 23 is prone to jamming or large-scale swinging, seriously threatening the stability and functional reliability of the device structure. Therefore, the risk of malfunctions in the clamping mechanism 2 can be reduced by limiting the rotation amplitude of the first clamping member 21 and the second clamping member 22.

[0057] Specifically, the clamping mechanism 2 may further include a limiting member 24, which may be correspondingly disposed on the support column 12, and at least a portion of the main body of the limiting member 24 may be disposed on one side of the first clamping member 21 and the second clamping member 22, so as to limit the rotation amplitude of the first clamping member 21 and the second clamping member 22 relative to the support column 12, thereby limiting the distance between the first clamping member 21 and the second clamping member 22, so that the included angle between the first clamping member 21 and the second clamping member 22 is within a stable range, that is, neither too large nor too small.

[0058] Generally, considering that the cylinder body 41 of the brake cylinder 4 has a certain specification range, the included angle between the first clamping member 21 and the second clamping member 22 is set accordingly to ensure that the cylinder body 41 of the brake cylinder 4 can be stably embedded or disengaged.

[0059] Generally, the limiting member 24 can also be fixed to the support 11, and can be flexibly installed according to the needs of the installation space. No specific restrictions are imposed here.

[0060] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, for ease of installation, the limiting member 24 can be directly sleeved on the support column 12 and can be locked on the support column 12 by fasteners.

[0061] It is worth noting that a portion of the main body of the limiting member 24 may extend to one side of the rotation direction of the first clamping member 21 and / or the second clamping member 22, so as to limit the relative rotation amplitude of the first clamping member 21 and the second clamping member 22 and limit the opening angle.

[0062] The limiting member 24 is provided with a stop part 241, and the stop part 241 can block one side of the rotation direction of the first clamping member 21 and / or the second clamping member 22 to stop the rotation of the first clamping member 21 and the second clamping member 22.

[0063] In some embodiments, the first clamping member 21 and the second clamping member 22 are both rotatable members, and the limiting member 24 can be configured as two members, respectively disposed on one side of the first clamping member 21 and the second clamping member 22, correspondingly stopping and limiting the first clamping member 21 and the second clamping member 22.

[0064] Generally, the first clamping member 21 and the second clamping member 22 can be regarded as a whole, and the two limiting members 24 can be located on both sides of the two clamping members as a whole, thereby reducing interference to the normal rotation process of the first clamping member 21 and the second clamping member 22.

[0065] It is worth noting that the two limiting members 24 can also limit the axial displacement of the first clamping member 21 and the second clamping member 22 on the support column 12, ensuring clamping reliability.

[0066] On the other hand, the positions of the limiting member 24, the first clamping member 21 and the second clamping member 22 in the axial direction of the support column 12 can be adjusted as needed to adapt to the press-fitting requirements of brake cylinders of different specifications.

[0067] In some embodiments, the limiting member 24 may be disposed between the first clamping member 21 and the second clamping member 22, and the stop portion 241 may be provided in two parts, respectively restricting the rotation of the first clamping member 21 and the second clamping member 22.

[0068] See Figure 3 and Figure 4 In some embodiments, in order to improve the structural strength and simplicity of the first clamping member 21, the first clamping member 21 may include a first clamping plate 211 and a first sleeve 212, with the first sleeve 212 connected to the first clamping plate 211.

[0069] The first sleeve 212 is sleeved on the support column 12, enabling the first clamping member 21 to rotate around the support column 12 and maintain a stable rotational posture.

[0070] One side surface of the first clamping plate 211 serves as the side surface of the cylinder body 41 that correspondingly contacts and clamps the brake cylinder 4, providing a larger contact area and thus improving clamping stability and reliability. Accordingly, the first clamping part 211a can be disposed on one side surface of the first clamping plate 211.

[0071] The first clamping plate 211 can be connected to the clamping drive cylinder 23 to rotate relative to the support column 12 under the traction of the clamping drive cylinder 23.

[0072] Generally, the shape of the first clamping part 211a can be adapted to the shape of the cylinder body 41 of the brake cylinder 4, thereby stably clamping the cylinder body 41 of the brake cylinder 4.

[0073] In some embodiments, in order to further strengthen the structure of the first clamping member 21, the first clamping member 21 further includes a first stiffener 213, which may be disposed on the first clamping plate 211 to improve the morphological stability and strength of the first clamping plate 211.

[0074] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, in order to reduce the impact on the shape of the first clamping plate 211, the cylinder rod 231 of the clamping drive cylinder 23 can be rotatably connected to the first stiffening plate 213.

[0075] See Figure 2 , Figure 5 and Figure 6 In some embodiments, the first clamping part 211a may be configured as a first limiting groove, thereby stably restricting the displacement of the cylinder 41.

[0076] Similarly, the second clamping part 221a can also be configured as a second limiting groove, thereby stably restricting the displacement of the cylinder 41.

[0077] The first limiting groove and the second limiting groove can be arranged opposite to each other to lock and fix the cylinder body 41 from both sides, thereby improving the reliability of the limiting and fixing.

[0078] In some embodiments, the first clamping part 211a and the second clamping part 221a may be formed by bending or stamping to form an arc-shaped plate structure, and the arc shape of the arc plate is adapted to the cylinder body 41 of the brake cylinder 4.

[0079] In some embodiments, considering that the cylinder body 41 of the brake cylinder 4 is subjected to a large pressure in the axial direction, in order to maintain positional stability, the side edge of the first clamping plate 211 near the cylinder head mounting flange 411 of the cylinder body 41 can be set as a first support surface 211c to contact and support the cylinder head mounting flange 411, ensuring the axial position of the cylinder body 41 is stable and improving the convenience of cylinder head press-fitting operation.

[0080] In some embodiments, the second clamping member 22 is also provided with a second sleeve 222, and the second sleeve 222 can also be rotatably sleeved on the support column 12 to realize the rotation of the second clamping member 22.

[0081] In some embodiments, considering that the first clamping member 21 and the second clamping member 22 are both mounted on the support column 12, in order to reduce the stacking height of the first clamping member 21 and the second clamping member 22, the number of the first sleeve 212 can be set to multiple, and the multiple first sleeves 212 are coaxially spaced apart, and the second sleeve 222 is coaxially embedded between two adjacent first sleeves 212.

[0082] Generally, the height of the first sleeve 212 can be slightly smaller than the height of the second sleeve 222.

[0083] It is worth noting that the second sleeve 222 can also be configured as multiple, and the multiple second sleeves 222 are staggered and interlocked with the multiple first sleeves 212, thereby taking into account the reliability of the rotational connection and the small stacking height to a certain extent.

[0084] In some embodiments, the second clamping member 22 may have a structure similar to that of the first clamping member 21, and may also include a second clamping plate 221, with the second sleeve 222 connected to the second clamping plate 221.

[0085] The second sleeve 222 is fitted onto the support column 12, so that the second clamping member 22 can rotate around the support column 12 and maintain a stable rotational posture.

[0086] One side surface of the second clamping plate 221 serves as the side surface of the cylinder body 41 that correspondingly contacts and clamps the brake cylinder 4, providing a larger contact area and thus improving clamping stability and reliability. Accordingly, the second clamping part 221a can be disposed on one side surface of the second clamping plate 221.

[0087] The second clamping plate 221 can be connected to the clamping drive cylinder 23 to rotate relative to the support column 12 under the traction of the clamping drive cylinder 23.

[0088] Generally, the shape of the second clamping part 221a can be adapted to the shape of the cylinder body 41 of the brake cylinder 4, thereby stably clamping the cylinder body 41 of the brake cylinder 4.

[0089] In some embodiments, in order to further strengthen the structure of the second clamping member 22, the second clamping member 22 further includes a second stiffener 223, which may be disposed on the second clamping plate 221 to improve the morphological stability and strength of the second clamping plate 211.

[0090] In some embodiments, in order to reduce the impact on the shape of the second clamping plate 221, the bottom 232 of the clamping drive cylinder 23 may be rotatably connected to the second stiffener 223.

[0091] In some embodiments, considering that the cylinder body 41 of the brake cylinder 4 is subjected to a large pressure in the axial direction, in order to maintain positional stability, the side edge of the second clamping plate 221 near the cylinder head mounting flange 411 of the cylinder body 41 can be set as a second support surface 221c to contact and support the cylinder head mounting flange 411, ensuring the axial position of the cylinder body 41 is stable and improving the convenience of cylinder head press-fitting operation.

[0092] In some embodiments, in order to reduce the risk of interference, the first clamping part 211a and the first stiffening plate 213 can be disposed on both sides of the first clamping plate 211, and the first clamping part 211a and the clamping drive cylinder 23 can be disposed on both sides of the first sleeve 212.

[0093] Similarly, the second clamping part 221a and the second rib plate 223 are disposed on both sides of the second clamping plate 221, and the second clamping part 221a and the clamping drive cylinder 23 are disposed on both sides of the second sleeve 222.

[0094] In some embodiments, the first clamping part 211a and the clamping drive cylinder 23 may also be disposed on the same side of the first sleeve 212, and the second clamping part 221a and the clamping drive cylinder 23 may also be disposed on the same side of the second sleeve 222.

[0095] In some embodiments, in order to adapt to the stop portion 241 for limiting and reduce the structural density in the area of ​​the limiting member 24 to reduce the risk of interference, a first stop arm 211b is provided on the first clamping plate 211, and the first stop arm 211b is positioned to match the stop portion 241. After the first clamping plate 211 rotates to a preset position, the first stop arm 211b abuts against the stop portion 241, preventing the first clamping plate 211 from rotating further.

[0096] Similarly, the second clamping plate 221 is provided with a second stop arm 221b, and the second stop arm 221b is positioned to match the stop part 241. After the second clamping plate 221 rotates to a preset position, the second stop arm 221b abuts against the stop part 241, preventing the second clamping plate 221 from rotating further.

[0097] In some embodiments, to accommodate the spring force within the brake cylinder, a lever mechanism can be provided between the press-fit drive cylinder 32 and the pusher 31 to amplify the thrust force, thereby reducing the requirements on the pusher parameters of the press-fit drive cylinder 32. Simultaneously, it can also reduce the internal installation density of the device structure to some extent.

[0098] Specifically, the pressing mechanism 3 further includes a connecting rod 33, the middle part of which is rotatably connected to the support column 12, the first end of which is pivotally connected to the top pressing member 31, and the second end of which is pivotally connected to the cylinder rod of the pressing drive cylinder 32.

[0099] The pivotal connection between the first end of the connecting rod 33 and the pressing member 31 effectively matches the rotation of the connecting rod 33 and the linear movement of the pressing member 31. Similarly, the pivotal connection between the second end of the connecting rod 33 and the cylinder rod of the pressing drive cylinder 32 effectively matches the rotation of the connecting rod 33 and the stationary oscillation of the pressing drive cylinder 32, thereby reducing the risk of jamming or seizing.

[0100] Generally, the rotational force arm of the top pressing member 31 to the support column 12 is smaller than the force arm of the press-fitting drive cylinder 32 to the support column 12, thereby amplifying the driving force of the press-fitting drive cylinder 32 through the connecting rod 33.

[0101] In some embodiments, in order to reduce the random swaying of the connecting rod 33, the connecting rod 33 can be configured as two rods, arranged parallel to each other on both sides of the support column 12, and the two connecting rods 33 are rotatably connected to the support column 12 through the same pivot axis.

[0102] Generally, the two connecting rods 33 can also be connected by a reinforcing beam to improve the overall strength and morphological stability of the two connecting rods 33, thereby ensuring the pressing operation accuracy and stability of the pressing mechanism 3.

[0103] In some embodiments, the pressing member 31 is further provided with an adapter groove, which may be disposed on the side surface of the pressing member 31 near the cylinder head 42 of the brake cylinder 4. When the cylinder head 42 contacts the pressing member 31, it can move stably along the adapter groove to complete adaptive positioning.

[0104] See Figure 7 and Figure 8 In some embodiments, a method for pressing a brake cylinder head is also provided, which, based on the above-mentioned brake cylinder head pressing device, achieves a convenient pressing operation according to the set pressing steps.

[0105] The pressing step includes:

[0106] The position of the cylinder body 41 of the brake cylinder 4 is matched and adjusted so that the cylinder 41 of the brake cylinder 4 is located in the clamping position of the first clamping member 21 and the second clamping member 22;

[0107] The clamping drive cylinder 23 is activated to clamp the first clamping member 21 and the second clamping member 22 to the cylinder body 41, and to keep the first clamping member 21 and the second clamping member 22 abutting against the lower edge of the cylinder head mounting flange 411 of the cylinder body 41, wherein the lower edge of the cylinder head mounting flange 411 is the edge away from the cylinder head 42.

[0108] The press-fit drive cylinder 32 is activated, driving the top pressing member 31 to push the cylinder cover 42 of the brake cylinder 4 towards the cylinder body 41.

[0109] The embodiments of this application have at least the following beneficial effects:

[0110] The brake cylinder head pressing device and method provided in this application are based on a support mechanism with a clamping mechanism and a pressing mechanism installed, thereby realizing the clamping of the brake cylinder body and the pressing of the cylinder head, thus achieving a certain degree of automated pressing operation, improving operational efficiency, and reducing labor intensity and safety risks. The clamping mechanism includes a clamping drive cylinder and a first clamping member and a second clamping member mounted on the support column of the support mechanism. The first and second clamping members can be relatively close or far apart to clamp and release the brake cylinder body under the drive of the clamping drive cylinder, thereby greatly simplifying the fixing and positioning operation of the brake cylinder, reducing labor intensity, and improving operational efficiency. Furthermore, the clamping structure uses matching rotatable clamping members, resulting in a simple overall structure that reduces structural complexity and scale, thus facilitating operation and use.
