Description

Sleeper rubber backing plate with shoulder

Technical Field

The utility model relates to the technical field of sleeper rubber pads, in particular to a sleeper rubber pad with a shoulder.

Background

The sleeper rubber backing plate of the shoulder is a rubber backing plate used for shock absorption and protection below the railway sleeper. The device is positioned between the railway sleeper and the track foundation, and plays roles of buffering, damping and dispersing load. The rubber pad is generally made of rubber materials, has good elasticity and durability, can effectively reduce rail vibration and noise, and prolongs the service life of the railway rail and sleeper. The sleeper rubber backing plate of the shoulder plays an important role in railway track engineering, and improves the safety and comfort of railway transportation.

The movement effect in conventional shoulder-tie rubber tie plates is mainly achieved by means of several key components. First, a rubber pad is made of an elastic material capable of being compressed, extruded or extruded as a train passes, thereby absorbing and dispersing vibration and impact force generated from the train. Secondly, the sleeper, as a structure supporting the rail and the track, supports the rubber pad and influences its movement effect, and some designs can provide even more elasticity and vibration absorbing capability. The rail is used as a track for running a train and is directly influenced by the moving effect of the rubber backing plate, and the good design can reduce the impact between the rail and the train and reduce the noise and vibration.

However, conventional shoulder-tie rubber tie plates often rely on the pressure of the train in terms of shoulder-tie to achieve adaptation, however, while being able to achieve adaptation, they are often not sufficiently rigid. This adaptation means that the shoulder pad can be deformed and adjusted according to the weight of the train and the forces generated by the movement to adapt to different situations and conditions, thereby reducing the impact on the track and the train. However, due to the elasticity and softness of the shoulder pad itself, insufficient rigidity may result in insufficient support and stability in some cases, particularly in the passing of high speed trains or heavy load trains, a sleeper rubber tie plate with a shoulder is proposed for solving the above problems.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, the embodiment of the utility model provides a sleeper rubber backing plate with a shoulder, which comprises a shell 1, wherein a rotating column 5 is rotatably connected inside the shell 1, the outer wall of the rotating column 5 is fixedly connected with a handle 4, one end of the rotating column 5 is fixedly connected with a threaded rod 8, one end of the threaded rod 8 is fixedly connected with a first fixing column 9, the outer wall of the threaded rod 8 is in threaded connection with a connecting ring 7, the outer wall of the connecting ring 7 is fixedly connected with a first connecting block 6, and the top of the first connecting block 6 is fixedly connected with a wedge block 2.

Specifically, when using a sleeper rubber backing plate with a shoulder, the handle 4 is manually rotated, and the handle 4 is forced to drive the rotating column 5 to rotate. Subsequently, by the rotation of the rotation post 5, the threaded rod 8 at one end is driven to start rotating. The movement of the threaded rod 8 then drives the first fixing post 9 to rotate together. Subsequently, the rotation of the threaded rod 8 also brings about the beginning of the movement of the connecting ring 7. The movement of the connecting ring 7 in turn brings the first connecting block 6 and the wedge block 2 into movement. This series of actions achieves the purpose of manually controlling the width of the wedge 2. In this way, the width of the wedge-shaped block 2 can be adjusted, so that the shoulder height of the sleeper rubber backing plate can be changed to adapt to different use requirements and working environments.

Specifically, subsequently, the slider 3 is subjected to pressure, causing the wedge 2 to move. The movement of the wedge-shaped block 2 drives the sliding block 3 to move continuously. The force of the wedge 2 causes the bottom damper rod 10 to contract. Subsequently, the force of the slider 3 causes the second connection block 13 and the connection rod 14 at the bottom to start moving. The movement of the connecting rod 14 drives the third connecting block 15 at the bottom to move, so that the lantern ring 17 is pushed to move. Movement of collar 17 causes second spring 16 to be compressed. At the same time, the second fixing post 11 in the housing 1 provides support, sliding the fixing block 12 and the collar 17 along the outer wall of the second fixing post 11. The series of actions jointly achieve the damping effect, and ensure the stability and reliability of the device in the running process.
