Description

[Detailed Description of the Invention] This invention relates to a device for holding an actuator on a wheel tread to which a brake element in a railway vehicle braking device or an abrasive element in a wheel tread surface cleaning device is attached.

Conventionally, in this type of holding device, the upper end of the action link is fixed to the drive shaft, and the lower end is attached to the action elements connected to the action element, and the action link is pressed against the wheel tread by rotation of the drive shaft. or pulling it away from the wheel tread.

Furthermore, since the actuators are attached to the actuators only by means of bolts or keys, if these break, the actuators may fall off from the actuators, which can easily cause an accident and pose a safety risk. There was a drawback that it could not be said that sufficient consideration was necessarily given.

The object of this invention is to provide a device for holding an actuator on a wheel tread which eliminates the above-mentioned drawbacks.

To explain the embodiment with reference to FIGS. 1 and 2, operator 1
There is a hole 3 for the connecting pin 2 at the tip in the vertical direction at the center of the back of the
A safety protrusion 4 with a U-shaped mounting member 5 is fixed to the actuator 1, and a pair of engagement protrusions 6 are provided on the back of the actuator 1 near the upper and lower ends of the central part in the width direction. , 6 are formed.

On the other hand, the central part of the coupling member 8 of the actuators 7 that contacts the back surface of the actuator 1 and a pair of perpendicular link receiving plates 9° 9 provided parallel to the back surface side of the coupling member 8 are , a nearly square hole 10 and a pair of rectangular holes 11, 11 are bored through which the safety protrusion 4 and the integral mounting member 5 pass, respectively, and engage with the engaging protrusions 6, 6 of the actuator 1. Engagement grooves 12 and 12 are cut out at both end edges of the upper and lower central portions of the coupling member 8.

When the width dimension of the mounting member 5 is made smaller than the interval between the link receiving plates 9, 9, the holes 11.1 bored in the link receiving plates 9, 9.
The drilling step 1 may be omitted.

Therefore, when the attachment member 5 of the operator 1 is inserted into the rectangular hole 10 of the coupling member 8 and the back surface of the operator 1 is brought into contact with the front surface of the coupling member 8, the engagement protrusions 6, 6 are inserted into the engagement groove 10. .12.

In this state, the hole 3 of the safety protrusion 4, the hole 13.13 provided in the link receiving plates 9, 9, and the hole at the lower end of the working link 14 are aligned, and the connecting pin 2 is inserted, and the working link 14 is activated. At the same time as attaching the child 1 and the actuating element 7, a spring steel tip 15 having a contact surface 15a is inserted into the mounting member 5, and a contact plate 16 fixed above the link receiving plates 9, 9 is used to tighten the tip 15.
The connection between the actuator 1 and the actuators 7 is completed by supporting the stopper piece 15b of No. 5 and holding the upper surface of the stopper piece 15b with the pin 18 set in the pin hole 17.17 slightly above the stopper piece 15b.

FIG. 3 shows the holding device for the actuator 1 of this invention, in which the upper end is connected to the action link 14 fixed to the drive shaft 19, and the rear ends of the link receiving plates 9, 9 are attached to the bogie frame 21 by means of the auxiliary link 20. An embodiment of the present invention is shown in which it is coupled to a fixed bracket 22.

24 is a cylinder, and 25 is a piston, which drives the drive shaft 19 along a path shown by a dashed line.

However, apart from this embodiment, this invention has an auxiliary link 2
It goes without saying that this can also be applied to cases where 0 is not used.

If the operator 1 is connected to the operator group 7 as described above, the play between the operator 1 and the operator group 7 can be eliminated by the action of the spring steel tip 15 during normal operation. Therefore, wear on the contact surfaces between the two can be significantly reduced, and the generation of noise on the contact surfaces can be suppressed.

In addition, even if the Kotsukuku 15 breaks, the operator 1
is connected to the operating link 14 together with the operating elements 7 by the connecting pin 2.
Since the actuator 1 is attached to the actuator 1, the danger of the actuator 1 falling off can be completely prevented.

In addition, even if the safety protrusion 4 is further broken, the U-shaped mounting member 5 will be deeply connected to the hole 10 of the coupling member 8, and the effector 1 will not fall toward the wheel 23 side. Since the structure is such that it cannot fall off to the 23 side, even in the case of double damage, it is possible to reliably prevent the danger of the actuator 1 falling off.

As is clear from the above explanation, according to this invention, accidents caused by the operator falling off from the operator group can be significantly reduced.
