Description

Technical Field

[0001] This utility model relates to the field of railway braking technology, and in particular to a railway brake deceleration bracket. Background Technology

[0002] Braking is a mechanical braking device that can slow down a vehicle. It is also known as a speed reducer. A railway train, also called a train or a car, refers to a vehicle that runs on railway tracks. It is usually composed of multiple carriages. According to the load, railway trains can be divided into freight cars and passenger cars, and there are also passenger and freight cars that combine both. The braking of a train is an important process for safely slowing down and stopping the train.

[0003] When the existing brake deceleration bracket is in use, the deceleration top slides inside the fixed seat due to the pressure from the wheel. Since the fixed seat is installed on one side of the rail, gravel may enter the interior, which may affect the sliding of the deceleration top inside the fixed seat and cause damage to the deceleration top, thus affecting its use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a railway brake deceleration bracket.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-4A railway brake deceleration bracket includes a fixed block 1 installed on one side of the rail. Multiple guide rods 5 are welded to one side of the fixed block 1. Sliding blocks 3 are slidably connected to the outer sides of two adjacent guide rods 5. Both sides of the fixed block 1 are provided with insertion assemblies for fixing the sliding blocks 3. A rotating block 4 is provided between two sliding blocks 3. A mounting hole is opened on the top of the rotating block 4, and a sliding sleeve 7 is fixed in the mounting hole by bolts. A deceleration top 2 is slidably connected inside the sliding sleeve 7. Rotating shafts 9 are welded to both sides of the rotating block 4. Rotating holes are opened on the opposite sides of the two sliding blocks 3, and the rotating shafts 9 are rotatably connected to the rotating holes. A deceleration top 2 is provided inside the sliding block 3. The locking assembly that fixes the rotating block 4 prevents the insertion assembly from fixing the slider 3. At this point, the slider 3 can be pulled to move along the guide rod 5. The slider 3 will drive the rotating block 4 to move. When the rotating block 4 moves to the appropriate position, the locking assembly will no longer fix the rotating block 4. At this point, the rotating block 4 can be rotated through the rotating shaft 9, thereby rotating the opening of the sliding sleeve 7 to face downwards. Then, the deceleration top 2 can be disassembled. This prevents gravel from entering the sliding sleeve 7 during the disassembly of the deceleration top 2, thus preventing the gravel from affecting the use of the deceleration top 2 and improving the safety of disassembling the deceleration top 2.

[0024] In this utility model, the locking assembly includes a third slide groove 22, which is opened in the slider 3 and is connected to the rotating hole. A slotted block 21 is slidably connected in the third slide groove 22. A cross groove 10 is opened on one side of the rotating shaft 9, and the slotted block 21 is inserted into the cross groove 10. A third spring 19 is provided in the third slide groove 22, and the two ends of the third spring 19 are fixed to the slotted block 21 and the slider 3 respectively. Pulling the slotted block 21 to move it and pressing the third spring 19 will cause the slotted block 21 to disengage from the cross groove 10 on the rotating shaft 9. At this time, the rotating block 4 can be rotated through the rotating shaft 9. When the opening of the sliding sleeve 7 is rotated to face downward, the slotted block 21 is then reset by the force of the third spring 19, so that the slotted block 21 is inserted into the cross groove 10 to fix the rotating block 4.

[0025] Specifically, the mating assembly includes two L-shaped clamping blocks 16, which are respectively disposed on both sides of the fixing block 1. A second sliding groove 18 is provided on each side of the fixing block 1. A round rod 12 is slidably connected within the second sliding groove 18. One end of the round rod 12 passes through the fixing block 1 and is fixed to the L-shaped clamping block 16. A second spring 11 is sleeved on the outside of the round rod 12, and both ends of the second spring 11 are fixed to the round rod 12 and the fixing block 1, respectively. A slot 8 is provided on one side of the slider 3, and the L-shaped clamping block 16 engages with the slot 8. A second spring 11 is provided on one side of the fixing block 1. A connecting assembly for synchronous movement of the two L-shaped clamping blocks 16 includes a gear 17. A clearance groove 13 is provided within the fixed block 1, and the gear 17 is rotatably connected within the clearance groove 13. First sliding grooves 14 are provided above and below the clearance groove 13 within the fixed block 1, communicating with the clearance groove 13. The gear 17 extends into the first sliding grooves 14. Racks 15, meshing with the gear 17, are slidably connected within each of the two first sliding grooves 14. The two racks 15 are respectively fixed to the two L-shaped clamping blocks 16. Pulling one side of the L-shaped clamping block... The L-shaped clamp 16 moves, and during this movement, the L-shaped clamp 16 drives the rack 15 connected to it to move along the first slide groove 14. The rack 15 drives another rack 15 to move through the gear 17. The other rack 15 pushes another L-shaped clamp 16 to move, thus causing the two L-shaped clamps 16 to move in opposite directions. During this movement, the L-shaped clamp 16 drives the round rod 12 to move out of the second slide groove 18, and at the same time, it compresses the second spring 11, thereby causing the L-shaped clamp 16 to disengage from the slot 8, thus preventing it from moving out of the second slide groove 18. The slider 3 is fixed. A hexagonal rod 20 is welded to one side of the slotted block 21. The hexagonal rod 20 passes through the third spring 19 and extends out of the slider 3. The outer sides of multiple guide rods 5 are all fitted with first springs 6, and the two ends of the first springs 6 are fixed to the slider 3 and the guide rods 5 respectively. The slider 3 will squeeze the first spring 6 during the movement. After the deceleration top 2 is disassembled and replaced, the slider 3 will be reset by the force of the first spring 6. A handle for pulling the L-shaped clamp 16 is fixed to one side of the L-shaped clamp 16 by bolts.

[0026] Working principle: When disassembly is required, pull one of the L-shaped clamps 16 to move it. During the movement of the L-shaped clamp 16, it will drive the rack 15 connected to it to move along the first slide groove 14. The rack 15 will drive another rack 15 to move through the gear 17. The other rack 15 will push the other L-shaped clamp 16 to move, so that the two L-shaped clamps 16 move in opposite directions. During the movement of the L-shaped clamps 16, it will drive the round rod 12 to move out of the second slide groove 18, and at the same time, it will squeeze the second spring 11, so that the L-shaped clamp 16 will disengage from the slot 8. At this time, the slider 3 can be pulled to move along the guide rod 5. The slider 3 will drive the rotation The rotating block 4 moves, and when it reaches the appropriate position, the hexagonal rod 20 pulls the slotted block 21 to move and compress the third spring 19, causing the slotted block 21 to disengage from the cross groove 10 on the rotating shaft 9. At this point, the rotating block 4 can be rotated via the rotating shaft 9, thus rotating the opening of the sliding sleeve 7 downwards. Then, the slotted block 21 is reset by the force of the third spring 19, locking into the cross groove 10 to fix the rotating block 4. The deceleration top 2 is then disassembled. This prevents gravel from entering the sliding sleeve 7 during disassembly, thus preventing gravel from affecting the use of the deceleration top 2 and improving the safety of disassembly. Furthermore, the terms "installation," "setting," "connection," and "sleeving" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral structures; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; or they can refer to internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
