Therefore, these and other directional terms should not be construed as limiting terms.
A tread sweeping device according to an embodiment of the present invention will be described with reference to fig. 1 to 3. A tread sweeping device according to an embodiment may include: a mounting base 1, a cylinder member 2, the cylinder member 2 including a piston rod 3 capable of performing a linear movement; a grinder rest 4, the grinder rest 4 being connected to the piston rod 3 and a grinder 5 being arranged on the grinder rest 4. During e.g. rail vehicle braking, the piston rod 3 pushes the grinder holder 4 so that the grinder 5 abuts against the wheel tread, acting on the wheel tread for tread cleaning purposes. In the embodiment, the coupling end of the piston rod 3 has two bolt holes, the coupling portion of the grinder holder 4 has a first jaw 41 and a second jaw 42, the first jaw 41 and the second jaw 42 have bolt holes corresponding to the positions of the bolt holes of the piston rod 3, respectively, and the first jaw 41 and the second jaw 42 are located on both sides of the coupling end of the piston rod 3, and it is shown in fig. 1 that the first jaw 41 is located on the lower side of the coupling end of the piston rod 3 and the second jaw 42 is located on the upper side of the coupling end of the piston rod 3. As shown in fig. 2, the first and second bolts pass through the bolt holes of the first jaw 41, the coupling end of the piston rod 3 and the second jaw 42, respectively, and are received by nuts 62 (only one nut is visible in fig. 1) outside the second jaw. One or more stopper members 43 for abutting against the bolt heads 61 of the first and second bolts are provided on the outer side of the first jaw 41, thereby restricting the first and second bolts from rotating. The rotation of the bolt during installation and operation is limited by one or more stop members 43 so that a bolt fulcrum is provided during bolt installation, bolt installation is facilitated and bolt rotational slippage is prevented during operation.
In the embodiment shown in fig. 1-3, the bolt heads 611,612 are each externally hexagonal. In other embodiments, the bolt head may have other shapes. In some embodiments, stop member 43 is formed as a boss located on the outside of first clip 41. In other embodiments, the member 43 may now also be formed as a groove recessed from the outer planar surface of the first jaw 41, and the head of each bolt may be disposed in the groove and abut the side walls of the groove. The recess may abut a face or faces of the bolt head, for example both faces or all faces.
In the embodiment shown in fig. 1 to 3, the bosses comprise a first boss 431 corresponding to the first bolt and a second boss 432 corresponding to the second bolt, respectively, the first boss 431 abutting against the bolt head 611 of the first bolt to prevent rotation of the first bolt, and the second boss 432 abutting against the bolt head 612 of the second bolt to prevent rotation of the second bolt. In some embodiments, the first and second bosses 431, 432 include first and second chamfers, respectively, that abut adjacent faces of the bolt heads 611,612 of the first and second bolts, respectively. More clearly, with reference to fig. 3, the first boss 431 has a first chamfer 4310, the first chamfer 4310 comprising two side edges 4311,4312, the two side edges 4311,4312 abutting against two adjacent edges 6111,6112, respectively, of the bolt head 611 of the first bolt, the bolt heads of the second boss and the second bolt may have the same or similar configuration. In alternative embodiments, the boss may have a trapezoidal shape to abut three sides of the bolt head, or other shapes to abut more sides, for example in one embodiment the boss may completely surround the entire bolt head.
Referring to fig. 1, in some embodiments, a first elastic member 71 and a second elastic member 72 are disposed between the inner sides of the first jaw 41 and the second jaw 42 and the coupling end of the piston rod 3, respectively, and a first bolt and a second bolt further pass through the first elastic member 71 and the second elastic member 72, respectively. The elastic member allows the grinder rest 4 and the grinder 5 to move with a small amplitude in the up-down direction in fig. 1. During installation of the bolt, due to the fact that the bolt head abuts against the limiting component, only specific torque needs to be applied to the nut end, and therefore assembly can be completed. The specific torque compresses the elastic members 71,72 to a predetermined degree. In some embodiments, two bolt holes are arranged in a transverse direction perpendicular to the piston rod moving direction, and the first bolt and the second bolt pass through the two bolt holes in the longitudinal direction. In alternative embodiments, the two bolt holes may not be arranged or referred to as being offset in the lateral direction.
With continued reference to FIGS. 4 and 5, another embodiment of a tread sweeping device is shown. In this embodiment, the boss 43 is integrally formed and has a flat end surface. The flat end surface of the boss 43 abuts against one face of the bolt heads of the first and second bolts simultaneously, and as shown in particular in fig. 5, the flat end surface 434 of the boss 43 abuts against the face 6115 of the bolt head 611, and the same flat end surface 434 of the boss 43 also abuts against one face (not shown) of the bolt head 612 in a similar configuration. The structure is more convenient to produce.
