Description

Technical Field

[0001] The invention relates to the field of wheel hoop buckle ring groove cleaning, in particular to a wheel hoop buckle ring groove cleaning device. Background Art

[0002] my country's railways are developing towards high speed and heavy load. The increase in train speed and axle weight makes the load condition of wheels, which are important load-bearing components of locomotives, increasingly severe. Therefore, in order to ensure the safe operation of trains, the safety and reliability design of wheelsets is very important. At present, wheels can be divided into two categories according to their structure: wheel rim wheels and integral wheels. Wheel rim wheels are made by installing the wheel rim on the wheel center by shrink fitting method and inserting buckles.

[0003] Compared with the integral wheel, when the wheel rim and tread of the wheel tyre are worn to a certain extent, the wheel tyre can be replaced and put back into use, which greatly extends the service life of the wheel set. The wheel tyre and rim of the assembled wheel are connected by interference fit to transmit traction and braking force. During use, the actual interference will be less than the necessary interference due to wear and temperature rise, resulting in relative movement between the wheel tyre and the rim. This relative movement is called relaxation. Wheel tyre relaxation can cause major safety accidents such as locomotive derailment. For example, on August 4, 2003, the 27031 freight train locomotive wheel A section 1, 2, 4 axles had serious faults such as wheel tyre relaxation and external movement, which caused the emergency stop, resulting in the interruption of the Longhai down line for 9 hours.

[0004] The rolling friction between the wheel tread and the rail will cause wear. When the rolling circle diameter of the wheel is worn to a certain value, the wheel tread is removed by a heating method and replaced with a new one so that it can continue to be used. However, due to various reasons, the wheel tread of the wheel with hoops is prone to loosening, causing the wheel tread to shift left and right on the wheel center, causing the distance between the two wheels to widen, and squeezing the two rails to cause accidents. In order to meet the requirements of railway heavy load speed increase, ensure transportation safety, and prevent the locomotive wheel hoops from loosening and running out, measures such as "using integral wheels for new locomotives" and "adding buckles to the original locomotive wheels with hoops" have been taken. Adding buckles to the wheel hoops can effectively prevent the wheel hoops of locomotives with wheel hoops from loosening and running out, which is one of the major measures to prevent train derailment or overturning accidents.

[0005] At present, the method of adding buckles to wheel hoops is as follows: for locomotive wheels that have not been equipped with buckles in the past, the buckles are added after the wheel hoops are removed for inspection and repair; for replacement of new wheel hoops, the rim and the buckle groove of the wheel hoops are first processed, and then the buckles are installed after the hoops are installed.

[0006] Before using the wheel hoop buckle, the inner groove of the buckle needs to be cleaned. Since the wheel hoop buckle is different from other standard parts, it is difficult to clean it, and there is currently no cleaning device for the wheel hoop buckle groove on the market. Based on this, the present invention proposes a wheel hoop buckle groove cleaning device. The cleaning device is a manual structure. When in use, the burrs, dirt, dust, oil, etc. can be processed by holding the support arm and using the three cleaning pieces on the inner side of the support arm. The device is simple and fills the gap in the prior art that the wheel hoop buckle groove cannot be cleaned. Summary of the invention
