Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple track straightening machine in which a track leveling, leveling and street correcting mechanism, a tamping mechanism, etc. are integrated.

Generally speaking, in order to ensure the safety of train operation, railway tracks have vertical deviations (height deviations) in the longitudinal direction of the top surface of the rails in straight and curved sections.
In order to eliminate deviations in the height of the left and right rails (leveling deviation) and longitudinal deviations in the longitudinal direction of the rail gauge line (driving deviation), it is necessary to constantly adjust the height, level, and street of the track. for that,
A straightening control device, a rail climbing device, a rail lateral movement device, and a tamping device are mounted on a track straightening machine that runs on the rails of the track, and the straightening control device detects the height, level, and street of the track. The rail lifting device, rail lateral movement device, and tamping device are controlled while comparing the detected signal with the set value to correct height deviations, level deviations, and running deviations of the track.

However, conventional track adjustment machines have separate mechanisms for correcting the height, level, and alignment of the track, as well as tamping mechanisms, resulting in a large and complex structure. In particular, those having a double-head type tamping mechanism for tamping two sleepers at the same time had the disadvantage of being particularly large.

The present invention has been made in consideration of the above points, and is a track straightening machine having the above-mentioned double-head type tamping mechanism, which performs various correction works such as height, level, and alignment of the track, and tamping work. To provide a simple track straightening machine whose main mechanism is integrated into the same frame, the structure is simplified, the size is reduced, and the weight is reduced, and the performance is comparable to that of conventional track straightening machines.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the simple track straightening machine of the present invention has a straightening mechanism section mounted on a frame 1 attached to a vehicle 18 (see FIG. 3) via a spherical receiver 31. Hydraulic cylinders 2 for lining (street alignment) are installed on the left and right sides of this frame 1, respectively.
3, and the hydraulic cylinders 32, 33
The compactor parts 34 and 35 are attached to the ends of the piston rods of the hydraulic cylinders 32 and 33 and have a vibration generator 22, and the compactor parts 34 and 35 can be moved in the vertical direction by the hydraulic cylinders 32 and 33. , and a foot compactor 4 capable of vibrating the compactor parts 34 and 35 by a vibration generator 22 as necessary.
5 is mounted on the frame 1 via a guide 30 so as to be movable in the vertical direction by hydraulic cylinders 6 and 7 for leveling (height/lowering, level adjustment), and wheels 36
rail catches 8 and 9 that are attached to the lift frame 17 and engage with the rails 20 and 20 by a rail catch hydraulic cylinder 28; Auxiliary foot compactors 11 to 14 are movably mounted and vibrated by a vibration generator such as a hydraulic motor (not shown) as necessary, and hydraulic cylinders (not shown) are provided at the front and rear of the frame 1, respectively. ), and is mounted so that it can be moved up and down by a hydraulic motor (not shown), and can be opened and closed in the front and rear directions by a hydraulic motor (not shown).
If necessary, the tamping mechanism is constructed of a double-head type tamping mechanism having a plurality of sets of tamping bars 15 and 16 which are vibrated by a vibration generator such as a hydraulic motor (not shown).

In addition, when this straightening mechanism is not in operation, the upper frame 1 is
7 is pulled upward relative to the frame 1 by the leveling hydraulic cylinders 6 and 7, and the frame 1 is fixedly held by the lock pin 19 so as not to swing during turning (the track straightening machine (running state), during straightening work, the upper frame 17
is lowered via the wheels 36 to a position where it abuts on the rails 20, 20', and the locking pin 19 is removed to release the fixation between the frame 1 and the vehicle 18. As shown in FIG. 4, each of the compactor parts 34 and 35 of the foot compactors 4 and 5 is equipped with a buffer spring 21 for absorbing vibrations during compaction with the track bed.
is provided. Furthermore, this compactor section 3
4 and 35 are foldable so that they can be positioned even on the slope of the roadbed (see Figure 1), and fins 23 are formed on their lower surfaces to prevent them from coming off. ing. Also,
Fins 24 are formed on the lower surface of each of the auxiliary foot compactors 11 to 14 to effectively compact the trackbed between the sleepers and to receive reaction force during tamping. In addition, 27 in Figure 3
shows a drive control section of the straightening mechanism section mounted on the vehicle 18.

The operation of the simplified track straightening machine according to the present invention configured as described above will be explained below.

First, when adjusting the height, level, and street of the track, the leveling hydraulic cylinders 6 and 7 are operated to lower the overhead frame 17, and its wheels 36 are brought into contact with the upper surfaces of the rails 20 and 20'. then slightly lift frame 1 and tighten lock pin 1.
9 is removed, and then the respective hydraulic cylinders 32, 33 of the foot compactors 4, 5 are operated to bring the respective compactor parts 34, 35 into contact with the track bed surface. At this time, when the compactor parts 34 and 35 are brought into contact with the slope of the track bed, the compactor parts 34 and 35 are bent along the slope, and when the compactor parts 34 and 35 are brought into contact with the flat part of the road bed, the compactor parts 34 and 35 are bent along the slope. Stretch out your eyelashes immediately. After that, when the straightening work is started, each detection of the height, level, and street of the track is performed by a straightening control device (not shown), and this straightening control device compares each detection signal with the set value. At the same time, the rail catches 8, 9, leveling hydraulic cylinders 6, 7, or lining hydraulic cylinders 2, 3 are operated to move the rails of the track upwards or sideways, and the height, level, and street of the track are corrected. . In this case, the reaction force during climbing and lateral movement of the rail can be received by the foot compactors 4 and 5. In addition, to explain the above-mentioned adjustment work in detail, in order to correct the height and level of the track, one of the rails 20 and 20', for example, the rail 20, is used as a reference rail, and the reference rail 20 is corrected for the height deviation. If there is, the catch hydraulic cylinder 28
The rail catch 8 catches the reference rail 20, and the leveling hydraulic cylinder 6 is operated to move the reference rail 20 in this manner until the height detection signal from the alignment control device matches the height setting value. Then, if the other rail 20' is out of level with respect to the reference rail 20 whose height has been corrected, the catch hydraulic cylinder 28 is operated. Rail catch 9 connects the other rail 2.
0' and leveling hydraulic cylinder 7.
is operated to raise the other rail 20' until the level detection signal from the alignment control device matches the level setting value, thereby correcting the level deviation of the other rail 20'. In this way, if there is a deviation in the trajectory that has been corrected for height and level, the lining hydraulic cylinders 2 and 3 are operated in the same direction, and the deviation detection signal from the correction control device is passed and the set value is adjusted. Slide the left and right rails 20 along with the sleepers until they match.
20' is moved laterally to correct the track deviation.

After adjusting the height, level, and track of the trajectory as described above, as shown in FIG.
6 into the trackbeds of the front and rear sides of the two sleepers 25 and 26 while vibrating them with a vibration generator.
Push in the tamping bars 15 and 16 in an open state, and insert the two sleepers 25 and 26 in the pushed in state.
Close the tamping bars 15 and 16 so as to sandwich the
Ballast is inserted into the lower part of the sleepers 25 and 26 to perform tamping work to compact the track bed, and at the same time, the vertical drive hydraulic cylinder 10 is operated,
Auxiliary foot compactors 11 to 14 are brought into contact with the track bed surface between the sleepers 25 and 26 to receive reaction force during tamping work. If it is necessary to further strengthen the compaction of the roadbed, the foot compactors 4 and 5 and the auxiliary foot compactor 11
- 14 individually or simultaneously with a vibration generator to compact the slope of the track bed or the flat part between the tracks of a double track and the track bed part between the sleepers 25 and 26. , completed the height, level and street adjustment of 26 parts of the track.

In this way, when the alignment of one place on the track is completed, the catch hydraulic cylinder 28 is operated to move the rail catches 8, 9 and the rails 20, 20'.
The compactor parts 34, 35 of the foot compactors 4, 5 are released from the hydraulic cylinders 32, 3.
At the same time, the auxiliary foot compactors 11 to 14 are raised from the track bed by operating the hydraulic cylinders 10, and the tamping bars 15 and 16 of the tamping mechanism are operated by the hydraulic cylinders. After lifting it above the middle of the track bed, the simple track straightening machine is driven by itself or towed and moved to the next straightening work position. On this occasion,
Wheels 36 provided on the lower side of the upper frame 17
The wheels 36 run while in contact with the rails 20, 20', and these wheels 36 also serve as guide wheels for the straightening mechanism. In addition, after all the track alignment work is completed, the rail catches 8, 9 and rails 20, 2
0' and operate the leveling hydraulic cylinders 6, 7 to lift the overhead frame 17 above the rails 20, 20' as shown in FIG. - If the compactors 4, 5, tamping bars 15, 16, and auxiliary foot compactors 11 to 14 are lifted above the track bed as described above, all mechanical parts will be separated from the track bed and above the rails 20, 20'. A lock pin 1 is inserted between the frame 1 and the vehicle 18.
By multiplying by 9, this track straightening machine is fixedly held in a rotating state.

As described above, the simple track straightening machine according to the present invention has a straightening mechanism section that includes a double-head type tamping mechanism that tamps every two sleepers, and a correction mechanism that adjusts the level, height, and street of the track. are integrated into the same frame, and its structure is simpler, smaller, and lighter than conventional track straightening machines that have the function of performing similar tasks, and it requires less than 1 unit for the task. Elevation, level, and street alignment can be performed using a single control sequence, and both workability and finishing accuracy are comparable to conventional track alignment machines. Furthermore, in the simple track straightening machine according to the present invention,
It has the advantage that the tamping bar of the tamping mechanism can be moved up and down independently so that the alignment work can be carried out sufficiently even in rail joint sections, guardrail sections, and obstacle sections.
