The invention provides a mounting frame 400 of a rail force detection device 300, which is used for mounting the rail force detection device 300 on a framework of a railway vehicle. The rail force detection device 300 acquires a rail force value by detecting an attitude parameter of the axle 100. The attitude parameter of the axle 100 may be a lateral or longitudinal deformation amount or other data of the axle 100. That is, the rail force detecting device 300 may detect various signals to achieve the acquisition of the rail force value. The specific type of the rail force detecting device 300 can refer to the prior art, and is not described in detail herein.
The mounting frame 400 of the rail force detecting device 300 provided by the invention comprises a horizontal part and a vertical part which are connected with each other, wherein two end parts of the horizontal part are respectively and rotatably supported on two braking clamp hanging seats 200 of a vehicle, and a rotating shaft is in a vertical direction, namely, the horizontal part of the mounting frame 400 can relatively rotate relative to the vertical shaft, so that when the vehicle turns, the mounting frame 400 can relatively rotate for a certain angle relative to the braking clamp hanging seats 200 in a horizontal plane, the use flexibility of the mounting frame 400 is improved, and the mounting frame 400 is prevented from being damaged due to overlarge stress.
The two end portions of the horizontal portion can be rotatably supported by the corresponding brake caliper hanger 200 through a rotating member, and the rotating member may be a bearing or other member for realizing the rotating function of the two.
Of course, on the basis of the above, the horizontal part can further realize the rotary connection in other directions on the premise of realizing reliable support. For example, the horizontal portion is fixed to the brake caliper hanger 200 by a ball-shaped support, so that the two are connected in rotation in multiple directions.
The vertical portion extends downward from the ground of the horizontal portion, the rail force detection device 300 is installed at the bottom end of the vertical portion, and the cross sectional dimension of the upper section of the vertical portion decreases downward from the horizontal portion in sequence.
The cross section perpendicular to the length direction of the component is referred to as the cross section in the present invention.

In addition, two ends of the horizontal part are supported on the two brake caliper hanging seats 200 through rotating parts, and the brake caliper hanging seats 200 can rotate at a preset angle on the horizontal plane so as to adapt to the adjustment of the positions of the brake caliper hanging seats and the brake caliper hanging seats during the turning of the vehicle and improve the working flexibility of each part.
