Description
Technical Field
The invention relates to a rail bottom slope repairing tool and application thereof, and belongs to the technical field of rail transit equipment.
Background
The rail foot slope (rail cant) is the lateral slope formed between the rail foot and the rail plane. The gradient of the rail bottom slope is matched with the gradient of the bus of the tread of the wheel, so that the rail bottom slope is kept to be dynamically centered all the time in the running process of the vehicle, and the derailment of the vehicle is prevented.
As a basic element of track geometry, the size and error of the rail bottom slope are directly related to driving safety and stability: the large rail bottom slope or the large continuous difference can aggravate the snaking motion of the train, and the running stability is deteriorated, and the serious shaking is visually represented. In addition, the larger rail bottom slope or larger continuous difference can affect the rail structure and other operation performances, and simultaneously, the maintenance workload is increased.
The effect of excessive rail base slope differences of adjacent bearing surfaces is manifested as: the wheel pressure deviates from the center line of the steel rail, the rail web stress of the steel rail becomes large, and longitudinal cracks can be generated when serious; the snaking movement is caused, the dynamic load impact effect is increased, other geometric shapes (track gauge, horizontal, high and low, direction and the like) of the track are deteriorated, the failure rate of connecting parts is increased, the track quality is deteriorated, and the maintenance workload is increased; the contact width of the tread of the wheel rail is increased (the contact light bandwidth of the steel rail is visually seen and is not straight), the creeping action of the wheel rail is increased, and the creeping action of the wheel rail is the main cause of the rail wave grinding; the shaking car and the larger rail bottom slope can aggravate the transverse wave power of the wheel rail, and the excessive transverse wave power of the wheel rail is also the main reason of abnormal wave grinding of the steel rail, especially the steel rail on the shock absorber on the curve.
GB50157-92 "design Specification for subway" specifies: the rail bottom slopes of the positive line and the auxiliary line can be between 1/50 and 1/30, and a determined value is selected; GB50090-99 railway line design Specification specifies: the rail bottom slope from the positive line to the departure line and the station line is 1/40; beijing subway lines are generally designed according to 1/40 rail bottom slopes, and later-stage lines also have 1/30 rail bottom slopes; all lines of other subways such as the Shanghai, guangzhou subways are designed according to a rail bottom slope of 1/40; national railway lines, including high-speed railway lines, are also designed according to 1/40 rail bottom slopes.
The rail bottom slope is an important geometric shape of the rail, is generally determined during design and construction, has almost no change during operation, is generally provided with no special measuring instrument for the rail bottom slope in the prior art, and is easily ignored during line maintenance. The subway line adopts a track structure with short sleeper or without sleeper, the rail bottom slope is adjusted on site by means of construction, the precision is difficult to control, and if the quality control is poor during construction, the precision of the rail bottom slope is difficult to ensure. The method brings great disadvantages to rail operation units, and a large amount of extra manpower and material resources are needed to be input to repair and remedy diseases caused by bad rail bottom slopes.
