Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an oblique finishing machine that flattens the surface of concrete after it has been compacted and rough finished using a finisher.

[Conventional technology]

A conventionally used concrete diagonal finishing machine (not shown) is equipped with a spreader and a drive device at the front and rear of a main body frame that maintains an oblique angle to the rail using hydraulic cylinders on all sides. The intermediate zone of the frame is provided with a vibrating screed and a smooth beam, so that movement on the rails is possible by the rolling of wheels connected to a travel motor. However, in the above-mentioned concrete diagonal finishing machine, the running span of the main body frame (distance during running between the left and right frame girders of the main body frame) is configured to have a constant width (fixed width) that cannot be adjusted.

[Problem that the invention attempts to solve]

Due to the above configuration, the conventional concrete slope finishing machine has the following problems.

(1) If the road surface width of the above-mentioned road is expanded or decreased from the previous road surface width due to reasons such as the road configuration of concrete pavement, the expanded or decreased road surface width. It was necessary to bring another concrete diagonal finishing machine to the site with a span that matched the existing concrete diagonal finishing machine and reinstall it by replacing it with the previous concrete diagonal finishing machine.

(2) Due to the above-mentioned re-installation, etc., double labor, time, and investment in machinery and equipment were required, and the construction of concrete pavement, which was handled by the diagonal finishing machine, became expensive.

[Means for solving problems]

This device is equipped with a spreader and a drive device at the front and rear of a main body frame that maintains an oblique angle to the rail by arranging hydraulic cylinders at the four corners, and a vibrating screed and a smooth beam in the middle zone of this frame. In a concrete diagonal finishing machine that can move on rails by the rolling of wheels connected to a running motor, a telescopic jack that diagonally intersects in the direction of the rail is built concentrically in the slide tube of the main body frame. The frame is constructed so that the span during running can be expanded or contracted by operating the jack.

[Effect]

For example, if the road surface width of the above road is wider or smaller than the road surface width immediately before it due to the road configuration of concrete pavement,
By operating the telescopic jack in the slide tube to adjust the running span of the main body frame to match the expanded road surface width or reduced road surface width,
The same model can be used to continuously construct concrete pavement surfaces of different road surface widths without having to be replaced with other concrete slope finishing machines. You can save money.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

First, to explain the configuration, as shown in FIGS. 1 and 2, the main body frame 2 maintains an oblique angle (approximately 30 degrees) with respect to the rail 1 due to the arrangement of hydraulic cylinders 5 and 6 at the four corners. A spreader 9 connected to a spreader motor 8 is provided on the front side, a drive device 4 using an engine or the like is provided at one end of the rear side, and furthermore, a drive device 4 connected to a vibration motor 10 is provided in the intermediate zone of the frame 2. A vibrating screed 11 and a smooth beam 13 connected to a reciprocating motor 12 are respectively provided in a front and rear arrangement, and the rolling of each wheel 14 connected to the traveling motor 7 located on both sides of the main body frame 2 causes the rails to be moved. In a concrete diagonal finishing machine that is capable of moving and traveling above 1, the main body frame 2
The slide tubes 2a have two slide tubes 2a of the same shape, in which a plurality of tubes of different diameters are slidably assembled concentrically at the front and rear of the slide tubes, and are arranged diagonally in parallel to each other in the left and right direction, with their base ends and tips extending downward in the front and back. It is assembled into a parallelogram with left and right frame girders 2b equipped with wheels 14 at intervals, so that it can expand and contract in a direction diagonal to the rail 2. Each slide tube 2a of the main body frame 2
Inside, a telescopic jack 3 having one end connected to the larger diameter side base of the frame girder 2b on each side is built in such a manner that each piston tip is connected to the smaller diameter side of the slide tube 2a at each position. . By operating each of the telescopic jacks 3, the span S of the main body frame 2 during traveling can be expanded or contracted, and the entire concrete slope finishing machine is constructed as a single unit. In addition, 15 is
This is a driver's seat attached to one end of the front part of the main body frame 2.

Next, the effect will be explained. When carrying out work using the concrete diagonal finishing machine of this invention, the concrete surface (not shown) is compacted and roughly finished by a finisher beforehand, and then the concrete surface (not shown) is spread by a spreader 9 connected to a spreader motor 8. The vibrating screed 11 can be smoothly and easily finished into a flat shape by making it uniform and sliding the vibrating screed 11 diagonally at 30 degrees by driving the vibrating motor 10. Furthermore, behind the vibrating screed 11 is a smooth beam 1 connected to a reciprocating motor 12.
3, the smooth beam 13 can be used to finish the concrete paving surface.

Due to reasons such as the road configuration for the above paving,
If the road surface width of this road becomes wider than the straight road surface width, first lift the frame girder 2b in the direction in which the main body frame 2 extends, and then
4 to deviate from the rail 1 directly below it. If the telescopic jack 3 is extended at this point, the small diameter tube portion of the slide tube 2a to which the tip of the piston is connected will extend outward beyond the rail 1 to the side. Therefore, by continuing to extend the telescopic jack 3, the traveling span S of the main body frame 2 can be increased by an arbitrary amount. In addition, the main body frame 2, which has been set to the desired expanded running span S as described above, moves and fixes the rail 1 under the wheel 14 at the position corresponding to this extended position, and then extends on this rail as described above. By mounting the side wheels 14, it is possible to continue working on the next concrete paving surface as a concrete diagonal finishing machine with an expanded span.

In addition, if the road surface width of the road is to be reduced from the previous road surface width, instead of expanding the road surface width as described above, the frame girder 2b on the contracting side of the main body frame 2 should be After deviating from the rail 1 directly below it, by compressing the telescopic jack 3, the traveling span S of the main body frame 2 can be reduced to a desired amount, and the rail 1 on this reduced side can be re-laid to the reduced position. This makes it possible to continue working on the next concrete paving surface as a concrete diagonal finishing machine with a reduced span.

[Effect of idea]

This device is equipped with a main body frame that maintains an oblique angle to the rail by arranging hydraulic cylinders at the four corners, and is equipped with a spreader and a drive device at the front and rear of the main frame, and a vibrating screed and a smooth beam in the middle zone of this frame. In a concrete diagonal finishing machine that can move on rails by the rolling of wheels connected to a running motor, a telescopic jack that diagonally intersects in the direction of the rail is built concentrically in the slide tube of the main body frame. Since the frame is configured so that the span of the frame can be expanded or contracted when running by operating the jack, for example, due to the road configuration of concrete pavement, the road surface width of the above road may be wider than the road surface width immediately before it. ,
Or, if it is reduced, operate the telescopic jack inside the slide pipe to adjust the running span of the main body frame to match the expanded road surface width or reduced road surface width mentioned above. Because the same model can be used to continuously construct concrete pavement surfaces of different road surface widths without having to be replaced, it is possible to save the redundant effort and time required to replace the model, as well as the investment in machinery and equipment. This has the effect of significantly reducing road surface construction costs.
