Description

The invention relates to the repair of railway rolling stock.

A device for routine delivery of wheel pairs for maintenance is known, comprising guides, a push-off lever pivoted from the drive, pivotally connected by means of a pull to a stop lever, pivoted in the direction 1, to it.

However, if the position is closely located on a line equipped with such devices, the latter does not have time to return to its original position and the wheelset rolls not onto the stop, but onto the pushing link of the device, which leads to device breakage.

In addition, at different distances between positions, adjustment is required at each position, and a device having an actuator obturator does not allow this.

The purpose of the invention is to expand the technological capabilities and increase the reliability of the device.

The goal is achieved by the fact that ycv; ioficTBO igguyu issuance of wheel sets of technical services; 1, a pivot arm pivotally connected by means of a pull to a stop lever, a ball Hp-i (, j fixed in a guide frame, equipped with switching bodies and a mechanism for alternately shifting wheel pairs , made in the form of one of the two spring-loaded two-arm levers installed on the outer side, which is connected by means of a rod with shifting organs and interacting with the wheel set, and the guide frame is a forked lever g with a transverse stop, placed with the ability to interact with the shank of the lever.

FIG. 1 shows the device in plan, view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 1 (view of the mechanism of alternate roll 1van wheelset fiapiii); in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. 2, i; a fig. 6 is a wiring diagram of the device in line; pas figs. 7 shows a conceptual pneumatic circuit for devices located in a line.

The device contains levers 1 with rollers 2, which (hinge through the pillar 3 hinge; 0 are connected with the thrust 4, which, in turn, is hingedly connected with the lever 5, which is rigidly connected with the stop lever 6, installed in the frame 7 and resting with the shank 8 on the transverse frame 9.

The pushing levers 1 are mounted non-movably at the ends of the shaft 10, installed in the bearings 11, which are fixed

on supports 12 installed inside the rails 13.

A lever 14 welded to the shaft 10 is pivotally connected to the power pneumatic cylinder 5, which is hinged at the other end 16 with the other end. On the outer side of the rails, the alternating rolling mechanism 17 of the wheel pair, which with its shank 9 passes through the slot, is hinged control rod 20 and is connected to it by axis 21. Lever npvzhinoy 22 rotated against the stop into the stopper 23. The rod 20 can move in the guide walls 24, pressing with a finger, 25. pneumatic valve 26 entil 28.

A pneumatic valve 29 is installed under the roller of the pushing lever. A valve is manufactured with the help of valves: and; rsk) a reduction of the pneumatic distributor. thirty,

The device works as follows.

A pair of wheels 31 cati-c on rails, fit into a stop 1) lever b ;; awns; - avlpE rts. The thrust lever is made as follows: To the effort from the wheelset sought to hang the lever clockwise. In doing so, the lever rests on the support of the frame 9 and stops the wheelset.

While rolling the nafia wheel sinks the lever 18 and release the bar 20; gives pneumatic valve 26 and presses

pneumatic valve 28. When the pushing lever 1 is in a horizontal position, it presses the needle valve 29.

on the return stroke, and the device occupies the initial position. The pair of wheels from the previous position again falls on the position that has been developed; 1il; -b. So

Thus, alternating wheelset rolls occur.

The operation of the alternate rolling mechanisms is that after removing the wheel from the last position, the alternate rolling of wheel sets to one position is performed.

At the last position, the pneumatic valve 28 is installed separately and pushed by the operator. For example, consider the operation of the mechanism when rolling from 11 position to IV, assuming that the 1st position is the last (Fig. 6 and 7).

Suppose all positions are loaded, pneumatic valves 33, 34 - 35 are pressed, since the pushing levers are in the lower position. The windshield was pressed 36 and 37, since the wheelsets are in position. Valves 38 - 40 not pressed. Therefore, the air in the left cavity of the valves 41 - 43 does not flow. Therefore, these distributors deliver air to the rod end of the cylinders 44 - 46 and the devices are in the initial position.

A wheel pair is dispensed from the next position, for which the operator presses the pneumatic valve 38, air is supplied through the pneumatic valve to the distributor 41, which supplies air to the super-cavity, and the rod valve is connected to the atmosphere. When the cylinder 44 extends, the wheelset rolls out from the 1st position. The operator releases the valve 38 and the valve 41 returns to its original position and, therefore, air is supplied to the rod end of the cylinder 44, the pushing and thrust levers return to their original position. But since there is no wheel at this position, under the action of the spring 22, the lever 18 rotates and presses the pneumatic valve 39. Air from the network through the valves 39, 33 and 36 is supplied to the distributor 42, which supplies air to the nadshtokovy cavity of the cylinder 45. Wheel pair from position III rolls to position 1U. As soon as it becomes in position 1U, it presses lever 18 and releases pneumatic valve 39, air from the left cavity of distributor 42 escapes through the valve to the atmosphere, and the valve supplies air to the rod end of cylinder 45 and, therefore, the pushing mechanism returns to its original position. But since the lever 18 of the mechanically alternating rolling at position III presses the pneumatic valve 40 under the action of the spring, the air from the network through pneumatic valve 40.34, 37 goes into the left cavity of the distributor 43 i-i and the wheel pair is fed from position 11 to position HI.

Similarly, the process of automatically alternately rolling wheelsets and from subsequent positions. Thus, pneumatic valves 39, 40 and 47 serve as a signal for the free ahead of the 0 position located. Pneumatic valves 36 and 37 serve as a signal for the presence of a pair of wheels in a feeding position. Pneumatic valves 33 and 34 serve as a return signal pushing its mechanism to its original position in the front position. With these three signals present, the wheelset is pushed.

Thus, the device allows to increase the reliability of operation by searching for the elements that work with slip, to expand the technological capabilities, since its design allows to establish different distances between positions, lines on which devices are installed, and at the same time optimally regulate the device by eliminating additional elements for fixing the wheel.

In addition, the proposed design of the device allows to significantly reduce the production area and to provide significant savings in air consumed for the drive of the device.
