Background
Tread sweepers are typically mounted on a rail vehicle in response to the wheels of the rail vehicle and controllably frictionally engage the wheel treads with abrasive blocks (or "grinders") mounted thereon to produce a tread sweeping effect on the vehicle treads. The friction effect can keep a relatively good adhesion state between the wheels and the track, and is beneficial to avoiding the problem that the rail vehicle idles or slides due to insufficient adhesion force between the wheels and the track in the starting, decelerating or braking process. Therefore, tread sweepers are one of the important parts installed in railway vehicles.
The tread sweeper needs to be positioned relative to the wheel on which it is acting during use, for example, by being fixedly mounted on the tread sweeper carrying portion of the truck. Therefore, the tread surface cleaners are generally provided with corresponding mounting seats for fixedly mounting the tread surface cleaners on the corresponding tread surface cleaner carrying portions. However, in some cases, the corresponding mounting mating surface (also used as a bearing surface) on the bearing part of the tread sweeper is not horizontally arranged, for example, the bearing surface has a large included angle with the horizontal direction, that is, the bearing surface is obliquely arranged, and the mounting angle has a certain inclination angle; in this case, in the process of fixedly mounting the tread surface sweeper on the tread surface sweeper bearing part, firstly, the heavy tread surface sweeper needs to be well positioned relative to the tread surface sweeper bearing part depending on manual external force, and the tread surface sweeper needs to be prevented from slipping down relative to the bearing surface due to the self gravity of the tread surface sweeper; therefore, the tread sweeper is difficult to install and position relative to the tread sweeper bearing part during the installation process.
Chinese patent application No. CN201621341200.4 discloses a general base tread cleaning device, in which a piston rod is installed in a body of the device, and an extending end of the piston rod is provided with a grinding block through a grinding block support; the base is provided with a hinge pin hole, a positioning pin hole and a sawtooth edge arc-shaped groove; the bottom of the body is provided with a hinge hole, a pin shaft hole and a curve groove; centering pins can be optionally inserted into the hinge pin holes, the hinge holes and the positioning pin holes; each sawtooth of the sawtooth edge has a 2 theta dividing angle relative to the hinge pin hole, and a composite pin shaft is arranged in the arc groove of the sawtooth edge; the width of the curve groove is matched with the diameter of the centering pin, and the center line of the curve groove is a curve determined by an equation set, so that the installation requirements of various inclination angles with the installation accuracy of theta can be met.

As shown in fig. 1 and 2, a tread surface cleaner 10 according to an embodiment of the present invention may be installed corresponding to a wheel of a railway vehicle according to an embodiment of the present invention, and the tread surface cleaner 10 includes a grinding block 110, a working surface (i.e., a grinding surface 111) of the grinding block 110 faces a tread surface 91 of the wheel, and when the tread surface cleaner 10 is triggered to perform a tread surface cleaning operation, the grinding block 110 acts on the tread surface 91 of the wheel to generate friction therewith, so that a relatively good adhesion state between the wheel and the rail can be maintained. The specific configuration and/or materials, etc. of the abrasive segments 110 are not limiting.
Continuing with FIGS. 1 and 2, tread sweeper 10 further includes brake head 120, air cylinder 130, etc.; the abrasive segments 110 are mounted on the brake head 120 in a manner that is not intended to be limiting.

Therefore, the air cylinder 130 can drive the grinding blocks 110 via the connecting portion, the brake head 120, and the like to be opposed to each other to be frictionally applied to the wheel tread 91.
As shown in FIGS. 1 and 2, tread sweeper 10 further includes a mounting block 180, and mounting block 180 is used to fixedly mount tread sweeper 10, such as by fixedly mounting tread sweeper 10 to a corresponding tread sweeper mount 810 of truck 80, to achieve alignment of tread sweeper 10 with respect to a rail vehicle wheel or wheel tread 91. When tread surface sweeper 10 is fixedly mounted, the distance between wheel tread surface 91 and abrasive surface 111 is approximately D in the stationary state. The connection between mount 180 and tread sweeper 10 is not limiting, for example, mount 180 may be connected to the body of cylinder 130 (e.g., integrally, detachably, or angularly adjustable); nor is the orientation in which mount 180 is located on tread sweeper 10 limiting.
The mounting base 180 of one embodiment of the present invention carries with it the mounting and positioning function during the mounting process, which is realized by means of the first positioning engagement portion 183 as shown in fig. 1 to 10, and the first positioning engagement portion 183/185 is provided on the mounting bottom surface 189 of the mounting base 180. Specifically, the mounting seat 180 has a base plate 181, and the lower surface of the base plate 181 corresponds to the mounting bottom surface 189, which is to be fitted to a mounting engagement surface 819 (i.e., a mounting surface) of the tread surface sweeper carrying portion 810, which is fixedly mounted, so as to face the ground. Correspondingly, in the railway vehicle according to an embodiment of the present invention, for example, the second positioning matching portion 811/813 is provided on the tread sweeper carrying portion 810 of the bogie 80, and the shape and/or size of the second positioning matching portion 811/813 may be designed according to the shape and/or size of the first positioning matching portion 183/185 according to the matching requirement, so that the first positioning matching portion 183/185 and the second positioning matching portion 811/813 may be matched with each other during the installation of the tread sweeper 10 on the tread sweeper carrying portion 810, and the matching prevents the tread sweeper 10 from sliding downwards relative to the inclined installation matching surface 819, thereby conveniently solving the problem that the tread sweeper 10 slides downwards relative to the installation matching surface 819 due to its own weight during the installation, and making the installation and positioning of the tread sweeper 10 on the bogie easier, the labor cost and the installation time are saved.
In the embodiment shown in fig. 3 to 8, the first positioning engaging portion 183 is a first positioning engaging protrusion 183, and correspondingly, the second positioning engaging portion 811 is a first positioning engaging recess 811 corresponding to the first positioning engaging protrusion 183; wherein first locating mating protrusion 183 extends at least partially into first locating mating recess 811, e.g., fits into first locating mating recess 811 so as to be located in first locating mating recess 811, thereby providing mounting location for tread sweeper 10 prior to bolting.
In mount 180 of the first embodiment as shown in fig. 3-5 and its mating tread sweeper carrier 810 of the first embodiment. The first positioning mating protrusion 183 is a wedge-shaped block (e.g., a trapezoidal block), and the first positioning mating recess 811 is a wedge-shaped groove (e.g., a trapezoidal groove); the notch of the wedge-shaped groove tapers from high to low along the angled mounting mating surface 819; the wedge-shaped groove has two wedge-shaped sides 812a and 812b, the angle of inclination of the wedge-shaped sides 812a and 812b being the same as the angle of inclination of the wedge-shaped sides of the wedge-shaped block, respectively. In the installation process, the wedge-shaped block can be placed into the wide opening section of the wedge-shaped groove, and when the wedge-shaped block obliquely slides downwards in the wedge-shaped groove to a preset position under the action of the self gravity of the tread sweeper 10, the two wedge-shaped side surfaces of the wedge-shaped block are respectively abutted against the two wedge-shaped side edges 812a and 812b of the wedge-shaped groove, so that the mounting seat 180 is prevented from continuously sliding downwards, and the mounting seat 180 is positioned on the tread sweeper bearing part 810 and is fixed without manual external force. The mounting brackets 180 provide mounting positioning that, for example, prevents the tread sweeper 10 from continuing to slide or rotate relative to the tread sweeper bearing 810, and also facilitates subsequent bolt tightening operations.
Specifically, the base plate 181 of the attachment seat 180 is provided with a plurality of (e.g., four) bolt fastening holes 182, and correspondingly, the tread surface sweeper carrying portion 810 may be provided with a plurality of (e.g., four) bolt fastening holes (not shown). When fastening the tread sweeper 10, each fastening bolt is inserted through the bolt fastening hole 182 of the base plate 181 and the bolt fastening hole of the tread sweeper carrier 810, and then screwed.
In order to prevent the wedge-shaped grooves from falling off, the opposite wedge-shaped sides 812a and 812b can be arranged to be inclined inward from bottom to top, that is, each wedge-shaped side is inclined inward in the direction from bottom to top, so that the upper openings of the wedge-shaped grooves form a closing-in structure relative to the bottom surfaces of the wedge-shaped grooves, and the width dimension of the upper openings of the wedge-shaped grooves is smaller than that of the bottom surfaces of the wedge-shaped grooves; correspondingly, the two wedge-shaped sides of the wedge block are also arranged inclined inward from each other from bottom to top, i.e. each wedge-shaped side is inclined inward in the direction from bottom to top. Like this, when the wedge slided to predetermined position downwards aslope in the wedge recess (two wedge sides of wedge offset with two wedge sides 812a and 812b of wedge recess respectively), the wedge is restricted in the wedge recess, not only provides the installation location, can prevent moreover that the wedge from droing from the wedge recess, makes things convenient for operating personnel to carry out subsequent screw thread fastening operation. Moreover, the anti-drop function can also bring the following effects: (1) in the running process of the railway vehicle, the wedge-shaped fit between the wedge-shaped block and the wedge-shaped groove can share part of force borne by the fastening bolt, the safety coefficient of the fastening bolt is improved, the fastening bolt is not easy to break under complex working conditions, and the requirement on the fastening bolt is reduced; (2) even if the fastening bolt is broken in the running process of the railway vehicle, the wedge-shaped matching between the wedge-shaped block and the wedge-shaped groove has the anti-falling function, so that the tread sweeper can be prevented from falling off in the running process, and the safe running of the railway vehicle is ensured.
As shown in fig. 4, the protruding height of the second positioning fitting protrusion 813 may be equal to the recessed depth of the second positioning fitting recess 185, or may be smaller than the recessed depth of the second positioning fitting recess 185.
