Description

Technical Field

[0001] The utility model belongs to the technical field of seamless line stress release, and more specifically relates to a rail collision device for seamless line stress release. Background Art

[0002] CWR, also known as seamless track or long rail track, is a modern railway track design method. Its main feature is that there are no traditional rail joints in the entire track section. On traditional railway lines, there will be obvious joints between two rails. These joints will not only increase the vibration and noise when the train is running, but also easily become the focus and difficulty of line maintenance due to wear and corrosion. Now many high-speed railways and urban rail transit systems have widely adopted CWR technology.

[0003] Stress relief of seamless rails is an important technical measure in railway engineering, mainly used to adjust and eliminate temperature stress in seamless rails. Since seamless rails will expand and contract under temperature changes in different seasons and at different times, this will cause temperature stress inside the rails. In order to adjust this temperature stress and keep it within a safe range, stress relief operations are required, among which rail collision is a commonly used method.

[0004] At present, most of the stress relief operations of seamless lines are still carried out manually by pulling the rail-impacting oil hammer back and forth to repeatedly impact the rail seat to relieve the stress. This method requires a large number of people, is labor-intensive, and takes a lot of time, and has low efficiency in relieving the stress of the rails.

[0005] Therefore, it is necessary to provide a seamless line stress release collision rail device to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a rail collision device for relieving stress of a seamless line to solve the above technical problems.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A rail-impacting device for stress release of a seamless railway comprises a steel rail and a rail-impacting seat arranged thereon, a rail-impacting vehicle is slidably arranged on the steel rail, and further comprises:

[0009] A driving mechanism is arranged on the rail and is provided with two of them. The two driving mechanisms are respectively located on both sides of the rail-impacting seat and the rail-impacting vehicle, and the two driving mechanisms are respectively used to drive the rail-impacting vehicle to move back and forth left and right;

[0010] The driving mechanism comprises two support seats arranged on the rail, a transmission box is arranged between the two support seats, a steel wire rope is arranged on the transmission box, and the movable end of the steel wire rope is connected to the rail-impacting vehicle;

[0011] The transmission assembly is arranged on the transmission box and is used for driving the rail-impacting vehicle to move through the steel wire rope.

[0015] A rope winding wheel is arranged on the second rotating shaft, and one end of the steel wire rope is wound and connected to the rope winding wheel.

[0016] Furthermore, the rail-crashing vehicle is provided with a connecting plate, a connecting hole is opened on the connecting plate, and the movable end of the steel wire rope is also provided with a connecting assembly for connecting the movable end of the steel wire rope to the connecting plate.

[0017] Furthermore, the connection component includes:

[0018] A support plate is arranged at the end of the steel wire rope, and a plug rod adapted to the connection hole is movably penetrated through the support plate;

[0019] A pull plate is arranged at one end of the insertion rod, and a first elastic member is arranged between the pull plate and the outer wall of the bracket plate.

[0020] Furthermore, a vertical plate is provided on the support seat, a sleeve column is provided on the vertical plate, a displacement cavity is opened inside the sleeve column, an inner column connected to the transmission box is slidably connected in the displacement cavity, and a second elastic member is provided between the end of the inner column and the inner wall of the displacement cavity.

[0021] Furthermore, a connecting rod is provided at the inner end of the inner column, and the other end of the connecting rod interactively penetrates the outer wall of the sleeve column and is provided with a stopper.

[0022] Furthermore, a telescopic member is disposed on the outer wall of the support seat, and a clamping block adapted to the rail is disposed at the telescopic end of the telescopic member.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this scheme, through the cooperation of the rail-impacting seat, the rail-impacting vehicle and the driving mechanism, the driving mechanism on the side closer to the rail-impacting seat mainly plays the role of pulling the rail-impacting vehicle to impact to achieve stress relief, while the driving mechanism on the other side mainly plays the role of pulling back the rail-impacting vehicle, thereby avoiding the current operation method of requiring multiple people to pull the rail-impacting oil hammer back and forth to repeatedly impact the rail-impacting seat to relieve stress, saving a lot of labor, greatly reducing costs, and also reducing operation time, greatly improving the efficiency of stress relief for rails, and can be widely used.

[0025] 2. In this solution, the wire rope can be connected to the rail-crashing car by connecting the connecting components on the wire rope with the connecting plate. The installation and disassembly are very simple and convenient, which reduces the connection time between the wire rope and the rail-crashing car and has a good use effect. The specifications of the driving mechanism and the rail-crashing car can also be adjusted according to actual needs, and the solution is highly practical.

[0026] 3. In this scheme, when the steel wire rope on the transmission box drives the rail-impacting vehicle to move and hit the rail-impacting seat, the transmission box will drive the inner column to buffer the displacement along the displacement cavity of the sleeve column when the force is applied. The movement of the inner column will compress or stretch the second elastic member, thereby absorbing part of the force applied to the transmission box and increasing its service life.
