Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ballast sweeper with a compactor for removing ballast on sleepers after straightening a track and further compacting ballast on a track bed.

[Prior Art] Track leveling involves lifting the rail using a rail lifting device and compacting the ballast below the sleepers using a tamping device. Furthermore, lining adjustment involves pushing the rail laterally with a cylinder for straightening the rail to correct irregularities in the rail running direction. After such track leveling and lining adjustment, the ballast scattered during tamping is on the sleepers, so conventionally, a ballast sweeper is used to remove this ballast from the sleepers.

Additionally, in order to increase the resistance to lateral movement of the track bed, rammers or the like were used to compact the ballast near both lengthwise ends of the sleepers.

However, compaction work using a rammer etc.
Since the process is carried out by manipulating the equipment, it requires a dedicated worker and has the disadvantage of poor work efficiency. Furthermore, the compaction work using a rammer or the like is accompanied by intense vibration and noise, which places a heavy burden on the workers and may cause problems such as health problems.

Furthermore, conventional ballast sweepers are self-propelled or towed devices that simply remove ballast from sleepers, whereas rammers and other compaction devices are carried by workers using other transport equipment. Because it is,
Two types of equipment with completely different properties are used for the continuous work of ballast removal and compaction, and the equipment must be set up separately, resulting in poor work efficiency and many inconveniences in terms of equipment management. Katta.

[Problems to be Solved by the Invention] The present invention was proposed to solve the problems of the prior art as described above, and its purpose is to remove ballast on sleepers and remove ballast on sleepers with a single device. To provide a ballast sweeper with a compactor capable of compacting ballast on a track bed, increasing the lateral movement resistance of the track bed, improving work efficiency and reducing the burden on workers.

[Means for solving the problems] The ballast sweeper with compactor of the present invention has the following features:

A lock nut 19 with a handle 18 is threaded onto it.

By the way, the support frame 13 has a guide shaft 12,
The first link consists of an upper horizontal part supported by the upper horizontal part 12 and a vertical part bent downward from the front part, and a first link supporting the compactor 10 made of the compact plate 21 and the vibration motor 26 at the lower end of this vertical part. The upper end of 20 is rotatably supported via a pin 20a'.

This first link 20 is connected to the short arm 2 on the support frame side.
0a and a long arm 20b on the compactor side are rotatably connected via anti-vibration rubber and a pin 20c. It is rotatably attached via '. Furthermore, recesses 20d and 20e are provided on the side edges of the long arm 20b to prevent the short arm 20a or the front end of the compact plate 21 from coming into contact with the long arm when the link 20 is bent. Furthermore, a cushioning material 21a is provided at the front end of the compact plate 21 to prevent contact between the long arm 20b and the compact plate 21 when the link 20 is bent.

On the other hand, a hydraulic cylinder 22 is attached to the center of the upper horizontal portion of the support frame 13 so as to be rotatable about a shaft 23, and a piston rod 22a of this cylinder 22 has a piston rod 22a at its tip, which supports the compact plate 21. The second link 24 is attached via a spherical joint 24a, vibration isolating rubber, and a pin 24a'.

On this support base 25, a cushioning material 25a when the link 24 is folded and a stopper 25b that restricts the rotation range of the link when the link 24 is extended are provided, sandwiching the connecting portion of the second link 24. It is being

As described above, the first and second links 20, 24
A vibration motor 26 is fixed to the upper part of the compact plate 21 of the compactor 10 supported by. The vibration motor 26 includes an eccentric weight rotated by a hydraulic, pneumatic motor, or electric motor, and vibrates in the radial direction about the motor shaft.

Further, on the upper part of this compact plate 21, a pair of front and rear support fittings 2 provided with engagement holes 27a, 27a are provided.
7, 27 are fixed, and on the other hand, a pair of front and rear brackets 28, 28 are provided on the side of the underframe 3b of the ballast sweeper, corresponding to the support fittings 27, 27. The brackets 28, 28 are also provided with engagement holes 28a, 28a, similar to the supporting metal fittings.
Further, pins 30, 30, which are inserted into the respective engagement holes when the compactor is stored, are removably supported by a receiving metal fitting 29 provided on the rear bracket 28.

The operation of the compactor-equipped ballast sweeper of this embodiment having the above-mentioned configuration is as follows.

First, in order to remove the ballast on the sleepers, the rotating brush 7 of the ballast sweeper body 1 is lowered onto the sleepers. The support bracket 5 is rotated downward about its base D. After the rotating brush 7 reaches the railroad ties, the motor 9 is driven to rotate the rotating brush 7, thereby removing the ballast on the railroad ties. This ballast removal work is performed continuously by moving the ballast sweeper main body 1 along the track while rotating the rotating brush 7 as described above.

On the other hand, at the same time as the ballast is removed from the sleepers, the left and right compactors 10 provided at the rear of the ballast sweeper body are lowered onto the ballast on the track bed, and the vibration motor 26 is activated to compact the ballast.

In this case, in order to adjust the compactor 10 so as not to interfere with the rails, attach a handle to the end 17 of the screw shaft 14 provided between the pedestal 11 and the support frame 13, and rotate the screw shaft 14. and the support frame 13 engaged therewith is moved in the longitudinal direction of the sleeper.
After the compactor 10 reaches the predetermined position, operate the handle 18 to tighten the lock nut 19.
By preventing the screw shaft 14 from rotating, the longitudinal position of the sleepers of the compactor 10 is determined.

In this way, with the compactor 10 having been positioned in the longitudinal direction of the sleepers descending onto the track bed, the vibration motor 26 is started to move the compact board 21
vibrate to compact the ballast. Also,
The vibration of the vibration motor is transmitted to the ballast sweeper body 1 via the support frame 13 that supports the compactor 10.
This can cause noise and wear of bearings in various parts. Therefore, in this embodiment, a bendable connection part is provided in the middle part of the first link 20 by means of a pin 20c via a vibration-proof rubber, and the second link 24 and the cylinder 22 are also made to be bendable. These links 20, 2 are connected by a pin 24a' via a spherical joint 24a and a vibration isolating rubber.
The bending of the compactor 4 at the connecting portion and the damping effect of the anti-vibration rubber combine to absorb vibrations in the longitudinal direction of the compactor 10, thereby preventing noise generation and wear of bearings in various parts.

As described above, according to the ballast sweeper with a compactor of this embodiment, the rotating brush 7 of the sweeper can remove the ballast on the sleepers, and at the same time, the compactor 10 can compact the ballast on the trackbed, improving work efficiency and saving labor. can be achieved.

Furthermore, in this embodiment, the rotating brush 7 and compactor 10 can be stored in the following manner after the work is completed.

That is, the rotating brush 7 of the sweeper is rotated against the piston rod 6a of the cylinder 6, contrary to the time when the work starts.
By retracting, the rotating brush 7 is rotated upward about the base D of the bracket 5. On the other hand, when the piston rod 22a of the cylinder 22 is retracted, the compactor 10 rises from above the railroad ties, etc. In that case, as the compactor 10 rises,
The first link 20 is bent so that its connecting portion protrudes forward, and finally the short arm 20a and long arm 20b forming the first link 20 are folded in half. . On the other hand, the second link 24
is pulled by the cylinder 22 and becomes in line with its piston rod 22a. In this way, the lifted compactor 10 is
7, 27 to the positions of the support brackets 28, 28 on the ballast sweeper side, insert the pins 30, 30 removed from the receiver 29 into the engagement holes of both,
Fix the compactor 10.

The ballast sweeper with compactor of the present invention is
As an example, it has the structure and operation as shown in the above embodiment, but its specific shape is not limited to the above embodiment. For example, instead of using the first and second links as supporting means for the compactor 10, the compactor 10 may be supported by cylinders and links both at the front and rear. Furthermore,
As for the means for fixing the stored compactor, in addition to fixing the support fittings and the bracket with pins, chuck-shaped clamping means or the like can also be used. Further, as a means for positioning the sleepers of the compactor in the longitudinal direction, in addition to the above-mentioned screw shaft, a cylinder may be used to adjust the distance between the pedestal and the support frame.

[Effects of the Invention] As described above, according to the ballast sweeper with a compactor of the present invention, the compactor can be stored in the ballast sweeper body, which is a simple method, and the ballast sweeper can be used to remove the ballast from the railroad ties. Ballast can be compacted, so
The finishing work of the track bed after track alignment can be carried out efficiently, and vibration and other burdens on workers are eliminated, and the lateral movement resistance of the track bed is not reduced.

In addition, in the present invention, the links used when setting the compactor to be stored also act as vibration absorbers of the compactor, so the synergistic effect with the vibration isolating effect of the vibration isolating rubber provided on the link parts provides even better vibration damping. The vibration function is demonstrated.

In particular, since the compactor needs to be raised and stored on the stand side during forwarding operation of the ballast sweeper, a hydraulic cylinder or the like is generally used. However, if the compactor and cylinder are rigidly connected as in each of the cited examples, the impact applied to the cylinder will be large, which will deteriorate the durability of the device. In the present invention, by supporting such a compactor with links and providing vibration-proof rubber on the links, it is possible to reduce vibrations transmitted from the compactor side to the cylinder despite the simple structure.

Furthermore, in a device like the present invention, which is equipped with a compactor and a ballast sweeper, it is important that one device does not have an adverse effect on the other device. Since the transmission of vibration to the ballast sweeper body can be reduced, there is no need to provide the ballast sweeper itself with anti-vibration measures similar to those for compactors, which is particularly effective.
