Description

[Detailed Description of the Invention] The present invention relates to a slab track filling layer scooping machine that is used to cut the deteriorated or damaged part when repairing the deteriorated or damaged part of the cement asphalt mortar layer of the slab track.

Generally, a slab track consists of a concrete road base 20 provided on the base and rails 23 as shown in the first diagram.
A cement asphalt mortar layer 21 is provided between the track slab (rail support body) 22 and the cement asphalt mortar layer 2.
1 deteriorates in strength and breaks as the years pass,
Particularly in locations subject to freezing in cold regions and locations subject to water leakage in tunnels, the strength of the corners and outer periphery of the cement-asphalt mortar layer 21 is severely degraded and the degree of damage is large.

Conventionally, deteriorated and damaged areas were scraped off using an electric hammer for road construction, a manual hammer, or a hand chisel, a formwork for injecting the filler was temporarily constructed, and the filler (expensive room-temperature curing epoxy or urethane-based elastic resin) was injected. death,
Deteriorated and damaged areas are being repaired. however,
Since the degraded/damaged areas are cut using an electric hammer, manual hammer, hand chisel, etc., the degraded/damaged areas interposed between the plate-shaped roadbed concrete 20 and the plate-shaped track slab 22 are Removing the desired depth from the side requires a lot of time and is not only inefficient, it also cuts more than necessary and requires expensive filler materials to be used for the repair. It has the disadvantage of requiring a large amount of

The present invention was made to improve the above-mentioned drawbacks, and it can quickly and efficiently cut deteriorated or damaged parts of the cement asphalt mortar layer.
Moreover, it is an object of the present invention to provide a slab track filling and layering machine that does not cut more than necessary.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 2 is a plan view of the same, and Figure 3 is a side view of the same, in which 1 is a low-height moving means, such as a moving truck, 2 is a caster thereof, and 3 is a swarf that enters the shaft of the caster 2. This is a skirt part to prevent rotation from being impaired. A sled may be used instead of the moving trolley 1. Reference numerals 4a and 4b are pivot plates fixed on the movable cart 1 with bolts and nuts 5, facing each other. Reference numeral 6 denotes an electric vibrating hammer driven by a voltage of 100V and a current of 11A, and the number of strikes is 2900 times per minute, and 7 is a handle thereof. The vibrating hammer may be of an engine-driven type, a hydraulic type, a pneumatic type, or the like. The vibrating hammer 6 is attached to the pivot plate 4
a, 4b on the horizontal axis 8 on the center of gravity of the vibrating hammer 6
It is rotatably pivoted by a and 8b.

Reference numeral 9 denotes a chisel (blade) bent in a direction perpendicular to the blade surface, and is detachably attached to the vibrating hammer 6. A plurality of types of chisels 9 are prepared with different blade widths W and different lengths, and are appropriately selected and used depending on the thickness and cutting depth of the cement asphalt mortar layer 21. The cutting edge 9a of the chisel 9 is angled as shown in the figure to improve cutting into the cutting surface. Reference numeral 10 denotes a pressing spring for pressing the chisel 9 downward.

Reference numeral 11 designates a pivot point 1 at one end at the front upper end of the movable trolley 1.
2 is pivotally supported by a pivot shaft 13, and is provided on the side of the movable trolley 1. Reference numeral 14 denotes an arc-shaped angle adjustment plate attached to the other end of the plate 11, and has a plurality of adjustment holes 15a, 15b, . . . . The angle of the contact plate 11 is adjusted by selecting one adjustment hole and fixing it to the movable cart 1 with bolts and nuts 16.

Next, a case will be described in which a deteriorated or damaged portion of the cement asphalt mortar layer 21 is cut using the device of the present invention.

First, as shown in FIG. 4, the angle of the contact plate 11 is adjusted according to the depth d of the deteriorated/damaged area. That is, an adjustment hole of the angle adjustment plate 14 is selected, and the angle adjustment plate 14 is fixed again to the movable cart 1 with bolts and nuts 16 through the selected adjustment hole 15e, and the angle of the contact plate 11 is adjusted. Further, a chisel 9 suitable for cutting deteriorated/damaged areas is selected and attached to the vibrating hammer 6. Next, the vibrating hammer 6 is driven to push the entire machine forward while abutting the abutment plate 11 on the cutting surface, and the cutting edge 9a of the chisel 9 cuts the deteriorated or damaged area. At this time, since only the blade width of the chisel 9 can be cut, the entire machine is pulled and moved backward, and the vibrating hammer 6 is rotated around the horizontal shafts 8a and 8b to cut the blade edge 9a of the chisel 9 as shown in Figure 5. Shift the position and while maintaining this state, move the entire machine forward again and use the cutting edge of the chisel 9 to cut the deteriorated/damaged areas. By repeating this process, the cement-asphalt mortar layer 21 is deteriorated/damaged. The entire area can be cut.

After cutting, filler is injected using a filler injection mold to repair deteriorated or damaged areas.

In addition, in the present invention, the contact plates 11 may be provided on both sides of the moving means, or the contact plates 11 may be fixed to the sides of the moving means. When the contact plate 11 is fixed, a chisel 9 having a length corresponding to the cutting depth d may be selected and used.

Furthermore, if the pivot points of the vibrating hammer 6 can be changed at two or more points 8a, 8b and 8'a, 8'b on the center of gravity as shown in Figure 3, the thickness of the cement asphalt mortar layer 21 can be considerably reduced. It can also be used in thick cases.

As described above, according to the present invention, a vibrating hammer is rotatably mounted on the moving means in a plane perpendicular to the track slab surface, and the vibrating hammer is provided with a longitudinal direction in a plane parallel to the track slab surface. This is a slab track filling and layer scooping machine that is equipped with a chisel bent in a dogleg shape that is removably attached and a contact plate that comes into contact with the side surface of the slab track on the side of the moving means. By moving the entire machine forward and backward with the contact plate in contact with the cutting surface of the machine, and by rotating the vibrating hammer to shift the position of the chisel's cutting edge, it is possible to cut the entire deteriorated or damaged part of the cement asphalt mortar layer. This can be done quickly and efficiently, and because only the depth of the deteriorated or damaged area is cut, and no more than necessary is cut, the amount of expensive filler used for repair can be minimized. This has the effect of keeping it at a minimum.

Furthermore, if the angle of the contact plate can be adjusted as in the embodiment, cutting can be performed to suit the depth of the deteriorated or damaged area without replacing the chisel.
By lowering the height of the moving means as much as possible and lowering the position of the chisel's cutting edge, it is possible to easily cut the lower part of the deteriorated or damaged area. The machine can be easily moved by lowering the height of the moving means as much as possible to lower the center of gravity of the entire machine, and by providing a skirt around the moving means to prevent the intrusion of cuttings. By making the cutting edge of the chisel have an angled cutting edge, it is possible to make a good cut into the cutting surface.
By placing the pivot point of the vibrating hammer on the center of gravity, it is easy to maintain the vibrating hammer in a state where it is rotated by the blade width of the chisel. By making it possible to change the pivot point of the vibrating hammer at two or more points on the center of gravity, it is possible to cope with cases where the cement asphalt mortar layer is quite thick.
