Description

Technical Field

[0001] This utility model relates to the field of hydraulic transmission equipment technology, specifically to an automatic parking brake cylinder for railway vehicles. Background Technology

[0002] To ensure a stable stop on the rails after a railway locomotive stops and does not move, parking sleds are placed under the wheels to brake them directly. These parking sleds are manually placed at the station, requiring workers to place each sled at its corresponding wheel. The large size and weight of the sleds make them inconvenient to carry manually. Furthermore, workers need to remove each sled individually before starting the vehicle, making the start-stop preparation process cumbersome. Existing automatic parking sled placement cylinder structures are complex and have poor stability, resulting in their limited use on railway locomotives. Therefore, a new parking brake cylinder structure is planned for design. Utility Model Content

[0003] The purpose of this utility model is to address the defects and deficiencies of the existing technology by providing an automatic parking brake cylinder for railway vehicles. This cylinder uses a hydraulic rod to drive the rotation of the support link structure, thereby raising or lowering the parking plow. It also features a parking plow pushing structure to achieve automatic control of the parking plow braking operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes a mounting bracket, and it also includes: A support frame, wherein the support frame is spun onto the mounting frame via a rotating shaft; The plow is mounted on the movable end of the support frame; The hydraulic rod is spun onto the frame via a rotating shaft, and the output shaft of the hydraulic rod is spun onto the support frame via a rotating shaft.

[0005] Preferably, a support guide rod is fixedly installed on the upper side wall of the plow, and a support guide sleeve is fixedly installed on the movable end of the support frame, with the support guide sleeve movably fitted onto the support guide rod.

[0006] Preferably, a drive guide rod is fixedly provided on the upper surface of the plow, a drive guide sleeve is movably sleeved on the drive guide rod, and the drive guide rod is arranged parallel to the support guide rod.

[0007] Preferably, a drive motor is fixedly mounted on the support frame, a threaded rod is fixedly mounted on the output shaft of the drive motor, a threaded sleeve is fixedly mounted on the drive guide sleeve, and the threaded rod is threadedly inserted into the threaded sleeve.

[0008] Preferably, a buffer spring is sleeved on the drive guide rod, wherein one end of the buffer spring is fixedly mounted on the end of the drive guide rod located on one side of the support guide rod, and the other end of the buffer spring is fixedly mounted on the drive guide sleeve.

[0009] Preferably, limiting wing plates are fixedly provided on both sides of the plow.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution designs a support frame that uses a hydraulic rod as a drive to lift and lower the plow, and sets the plow on the support frame, thereby realizing the automatic lowering or retraction of the plow through the hydraulic rod drive. 2. This solution involves setting a threaded rod on the support frame that is driven by a motor to rotate, and connecting it to the parking plow through a threaded sleeve, a drive guide sleeve, and a drive guide rod. This allows the parking plow to be pushed against the wheels to achieve a braking effect after the parking plow is leveled. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-4 As shown, the specific implementation adopts the following technical solution: It includes a mounting bracket 1; characterized in that it further includes: Support frame 2, which is spun onto mounting frame 1 via a rotating shaft; A support guide sleeve 6 is fixedly mounted on the support frame 2 at one end away from its axial end; The plow 3 is disposed on the side of the mounting frame 1; A support guide rod 5 is fixedly installed on the upper surface of the plow 3, and a support guide sleeve 6 is movably sleeved on the support guide rod 5. Hydraulic rod 4, the hydraulic rod 4 is spun onto the frame via a rotating shaft, and the output shaft of the hydraulic rod 4 is spun onto the support frame 2 via a rotating shaft; The drive guide rod 7 and the support guide rod 5 are fixedly installed on the upper side wall of the plow 3, and the drive guide rod 7 and the support guide rod 5 are arranged parallel to each other. A drive guide sleeve 8 is movably sleeved on a drive guide rod 7; Threaded sleeve 11, which is fixedly mounted on drive guide sleeve 8; The drive motor 9 is fixedly mounted on the support frame 2; Threaded rod 10, the threaded rod 10 is fixedly mounted on the output shaft of drive motor 9; The buffer spring 12 is sleeved on the drive guide rod 7, and one end of the buffer spring 12 is fixedly set on the drive guide rod 7 at one end located on the side of the support frame 2, and the other end of the buffer spring 12 is fixedly set on the drive guide sleeve 8. The limiting wing plate 13 is fixedly installed on the side of the plow 3.

[0018] When using this device, the mounting frame 1 is fixed to the locomotive frame. When the locomotive wheels are braked to a stop, the hydraulic rod 4 pushes the support frame 2, causing it to rotate and level. The support frame 2, through the support guide sleeve 6, drives the support guide rod 5, which in turn drives the parking plow 3 to level and mount it on the rail. Then, the drive motor 9 drives the threaded rod 10 to rotate, which pushes the threaded sleeve 11 to move closer to the support frame 2. The drive guide sleeve 8, through the buffer spring 12, pushes the drive guide rod 7, which in turn drives the parking plow 3 to lock onto the locomotive wheels. As the parking plow 3 moves, it drives the support... The support guide rod 5 moves within the support guide sleeve 6; when the plow 3 abuts against the locomotive wheel, the support guide sleeve 6 is located in the middle section of the support guide rod 5, and the drive guide sleeve 8 is located on the drive guide rod 7 and presses the buffer spring 12; when the plow 3 is pulled out from under the locomotive wheel and retracted, the threaded rod 10 drives the drive guide sleeve 8 to move away from the support frame 2 and abut against the end of the drive guide rod 7 away from the support frame 2. Then, as the drive guide sleeve 8 continues to move, the drive guide sleeve 8 pushes the plow 3 out from under the wheel. Then, the hydraulic rod 4 pulls the support frame 2 upward, causing the support frame 2 to rotate and drive the plow 3 to rotate and lift.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This device sets up a support frame 2 and fixes a support guide sleeve 6 on the support frame 2. A support guide rod 5 is set on the plow 3. Through the cooperation of the support guide sleeve 6 and the support guide rod 5, the support frame 2 is lifted and lowered, and the plow 3 is pushed to lock the wheel. The hydraulic rod 4 drives the support frame 2 to rotate, thereby realizing the hydraulic control of the plow 3. 2. This device has a drive motor 9 and a threaded rod 10 on the support frame 2, a drive guide rod 7 on the plow 3, and a drive guide sleeve 8 on the drive guide rod 7. The forward and backward movement of the plow 3 is controlled by the threaded sleeve 11 on the drive guide sleeve 8 cooperating with the threaded rod 10, thereby realizing the automated motion control of the plow 3.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features.
