TRAVELING WAY GRINDING MACHINE OF AUTOMATED GUIDEWAY TRANSIT TYPE LIGHT WEIGHT RAILWAY}

The present invention relates to a traveling road polishing device for a guided track-type rubber wheel light rail, and more specifically, to allow the driving path to be polished linearly in the same manner as the track of the guide track at the time of construction of the road or after construction of the road. The present invention relates to a traveling path polishing device for a guided track type rubber wheel light rail that can improve construction efficiency and precision of a traveling road and prevent waste of money due to post-work polishing.

In general, lightweight trains (hereinafter referred to as light rail) are classified into steel wheel AGT (Automated Guideway Transit), rubber wheel AGT, LIM, monorail, streetcar, maglev railway, and the like.

As shown in FIG. 6, the rubber wheel AGT of the light rail employs a rubber tire to the wheel 50 to travel on the driving path 52 of the track roadbed 51, and the vertical wall of the roadbed 51. The guideway 54 installed at 53) and the guide roller 55 installed at the vehicle W operate while guiding the progress of the vehicle W. Most of which connect the inner city circulation or the sub-center with the inner city It is constructed to perform a function.

Of course, the driving path 52 is formed by pouring concrete to the outside of the reinforcement 56.

Since most of the light rails are built underground and elevated in urban areas, the linearity of the route is complicated by the change of many vertical and planar curves. In general, the linearity of the route is designed on the principle of straightness and flatness. However, due to the nature of light rail, many curves and gradients must be set.

As described above, the rubber wheel AGT is a tire in which the rubber wheel 50 travels on the driving path 52, and precisely so that the driving path 52 has an appropriate inclination according to the transverse and longitudinal inclinations of the light rail track. The construction of the light rail will be stable.

The construction method of the above-mentioned rubber wheel AGT is a track work for installing the guide track 54 on the side in the state in which the traveling road 52 is installed by proceeding the civil works.

That is, while installing the reinforcement 56 in the installation position of the driving path 52, the drain pipe and the system pipe are installed, and the formwork for pouring concrete is installed in the vicinity of the above-mentioned reinforcement 56.

The barley 56 is to be processed in advance in the factory according to the gradient of the track according to the design drawings, and to be brought to the site, to place the barley 56 at a predetermined installation position to be installed in accordance with the gradient of the line, the above installation At the time, the back bar 56 should be installed precisely in accordance with the transverse and longitudinal gradients of the track.

After the formwork is installed, the concrete is evenly coated with an adhesive such as an epoxy resin on the back muscle 56, and the top surface is flattened.

In particular, although the machine is used in the above-described concrete pouring process, it is difficult to match the gradient in the curved portion of the track, so that the worker constructs the manpower by manually adjusting the gradient.

In the compaction process of the above-mentioned concrete, the concrete leveler after the compaction of the concrete to measure the flatness of the concrete (1.2 mm or less per 3 meters), height (3 mm or less per 3 meters), planarity (3 mm or less per 3 meters) and the like.

When the concrete is finished and compacted, the concrete is cured for a certain period of time, then the formwork is removed and a joint is formed with a concrete cutter.After the joint is formed, a leveling layer is placed on the roadbed for waterproofing and height adjustment. .

When the leveling layer is completed, the guide track 54 is installed on the roadbed vertical wall 53 positioned at the side of the driving path 52, which guides the guide track 54 by the predesigned design. As it is installed at 53, the height is measured and installed on the basis of the roadbed 51, so that the rotational and longitudinal gradients of the track can be accurately aligned.

When the installation of the guide track 54 is completed, a separate inspection vehicle runs based on the roadbed 51 to measure the lateral and longitudinal gradients of the driving path 52. The furnace 52 is polished or concrete is added to the driving path (thin pavement) to achieve a gradient.

As described above, if the installation of the roadway, which is civil engineering, is installed first, and then the guide track is installed, it is difficult to align the lateral and longitudinal gradients of the roadway according to the design drawing, and in particular, the curvature and the slope are linear. Since it is practically impossible to accurately match the gradient of the curved road (relaxation curve section) that changes to, the process of polishing the roadway in the later process is required, which greatly increases the construction cost and guides the low grinding precision. Since the alignment of track and driving line does not coincide, it causes noise and vibration when driving light rail vehicles.

Therefore, in the "Applicable method for constructing a traveling track of a guided rubber wheel light rail, and a suitable construction device" filed by the present applicant with a patent application No. 2008-102080 dated October 17, 2008, a guide track, which is a track construction, is first constructed on a vertical wall of a roadbed. A construction method for constructing a driving path having a trajectory consistent with the guide track while driving on a guide track afterwards is disclosed.

However, as described above, after the driving track is formed to have the same trajectory (lateral and longitudinal gradients) as the guide trajectory while driving on the guide track, the surface of the driving path is smooth and accurate transverse and longitudinal gradient (trajectory). When polishing to have a), the accuracy of the traveling path can be further improved.

In addition, when the trajectory of the traveling path is polished on the track where the trajectory does not coincide with the guide trajectory, it is impossible to polish the coincidence to match the linear trajectory of the guide trajectory. There is a problem.

Therefore, an object of the present invention is to solve the above problems, by allowing the upper surface of the concrete-poured runway to be polished to match the trajectory (longitudinal and transverse gradient) of the guide track while driving the fog track. The present invention provides a traveling path polishing device for a guided track type rubber wheel light rail configured to maintain uniformity in the upper surface of a traveling path.

In order to realize the above object, the present invention provides a polishing machine main body having one or more rollers provided on a side surface so as to operate in a guide track, and a plurality of abrasives are provided on the bottom surface of the polishing machine main body. And a grinding means provided rotatably in the frame, and driving means provided to rotate the abrasive of the above-described polishing machine at a constant speed.

As described above, in the present invention, when constructing a track of light rail, the track of the light rail is constructed by first constructing a guide track on the vertical wall of the roadbed and then grinding the driving track to be the same as the track of the guide track while driving on the track. This has the advantage of being shortened and improving the construction accuracy of the track.

1, 2, and 3 are exploded perspective views and side and front views showing a driving path polishing apparatus for a guided track rubber wheel light rail according to the present invention, one or one on one side of the guide track 54 for driving. It is provided not only in the grinding | polishing machine main body 2 in which the above roller 1 is provided, and the bottom face of the said grinding | polishing machine main body 2, but is supported by the buffer means, and many abrasive materials 3 are attached to the frame 4, It consists of the grinding | polishing machine 5 provided rotatably and the drive means provided so that the grinding | polishing material 3 of the said grinding | polishing machine 5 can be rotated by a fixed speed.

The polishing machine 5 is provided in two rows, and when the polishing machine 5 is installed in a plurality of rows, the polishing degree can be precisely achieved.

Of course, if the height difference is set according to the heat of the polishing machine 5, the polishing machine 5 is polished sequentially by a predetermined amount, so that the polishing applied to the polishing machine 5 can be made smaller.

The shock absorbing means is provided between the grinder 5 and the grinder main body 2 so that the grinder 5 can be bent at an angle. As shown in FIG. The hinge 6, the second hinge 8 which is coupled to the first hinge 6 and the hinge shaft 7 and is rotatable and fixed to the polishing machine body 2, and the polishing machine 5 One end is supported by the frame 4 and the other end is supported by the grinding | polishing machine main body 2, and consists of the spring 9 which applies elasticity when the grinding | polishing machine 5 is folded back about the hinge axis 7.

That is, when an excessive load (such as a part protruding into the runway concrete) is applied to the grinder 5 described above, the grinder 5 is automatically folded backward to reduce the load and to pass the load to the elasticity of the spring 9. By returning to the original state.

The driving means is installed in the main body 2 of the grinder, and is provided to drive the respective grinders 5, and transfers the driving force of the motor 10 to the respective grinders 5. And a pulley 11 and a belt 12 for rotating the abrasive 3.

Of course, even if the pulley 11 and the belt 12 described above are used as a universal power transmission means such as a chain, the effect is the same.

As described above, using the same number of motors 10 as the number of the grinding machines 5 makes it easier to control each grinding machine 5, but the manufacturing cost is high and the weight becomes heavier. As shown in the figure, the driving force generated in one motor 10 is transmitted to two or more than two grinders 5, so that the weight of the polishing apparatus is light.

In other words, the pulley installed in the motor 10 can be used to drive a plurality of grinding machines (5) by using a pulley (11 ') capable of hanging two belts and the transmission pulley (13) for power transmission. It can also be configured to do so.

Referring to the operation and effect of the present invention as described above, in the light rail track construction, first guide rail 54 is installed on the vertical wall 53 of the roadbed 51 as designed.

In this state, after the worker arranges the back muscle 56 in accordance with the blueprint for the installation of the above-mentioned driving paths, the construction of the driving paths is carried out. The furnace 52 will be constructed.

After the concrete is poured, the longitudinal and transverse trajectories are formed on the upper surface of the concrete to coincide with the trajectory of the guide trajectory 54 and then cured.

When the forming of the driving path 52 is completed, the polishing machine body 2 is seated on the guide track 54 to allow the roller 1 to travel on the guide track 54 and the abrasive 3 of the polishing machine 5. Is in close contact with the upper surface of the driving path (52).

In this state, when the abrasive 3 is rotated at a constant speed by operating the motor 10, the abrasive 3 rotates to polish the upper surface of the traveling path 52. The above-described abrasive body 2 is accurately Since the trajectory moves along the guide trajectory 54 made of the trajectory according to the design drawing, the upper surface of the driving path 52 is polished according to the trajectory of the guide trajectory 54.

That is, when the polishing machine main body 2 is driven in the guide track 54 without the flatness and the gradient test after completion of the driving path 52, the grinding is performed in the same path as the guide track 54. Post-processing and polishing of (52) can be made very simple.

If there is a bent or protruding portion of the driving path 52 during the polishing process, the polishing material 3 of the polishing machine 5 is not caught, and the polishing body 2 is difficult to move forward. At this time, the above-described polishing machine (5) is to be polished while being rolled back and ride over the protruding portion at the same time.

For example, when the front grinder 5 is caught and flipped over by the protruding portion of the driving path 52, the protruding portion is polished a little, and the rear grinder 5 is applied to the protruding portion again. Polishing will make the grinding work better.

Here, the above-described grinding machine body 2 can be used even in the light rail track where the traveling road 52 is already constructed in accordance with the existing construction method. While driving (54), it is possible to finely polish the traveling road 52 constructed non-uniformly by the existing method.

As described above, when the grinder body 2 polishes the driving path while driving on the guide track 54, there is no need for a separate inspection process after construction of the driving path 52 as in the prior art, and the worker manually polishes the driving path. It can prevent excessive time spent and construction cost increase.
