Description

Road vibrator of guide rail type rubber wheel light rail {VIBRATOR OF AUTOMATED GUIDEWAY TRANSIT TYPE LIGHT WEIGHT RAILWAY}

The present invention relates to a driving path vibrator of a guide-rail rubber wheel light rail, and more particularly, to vibrate the driving path continuously while driving in a guide track like a light rail vehicle after construction of the driving path to remove voids in the formwork. It relates to a running path vibrator of a guide-track rubber wheel light rail.

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. 5, the rubber wheel AGT of the light rail employs a rubber tire to the wheel 50 so as 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, an adhesive such as an epoxy resin or the like is uniformly coated on the back muscle 56, and concrete is poured 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 first runway is installed after the installation of the roadway, which is a civil engineering work, then the trajectory and trajectory of the roadway are difficult to fit according to the design drawing. 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, after placing the traveling road concrete while driving on the guide track as described above or after the operator places the traveling road concrete while fitting the upper surface of the traveling road road manually, the vehicle travels to fit the track of the guide track. Although the trajectory of the runway can be maintained more precisely by flattening the upper surface of the furnace concrete, it is very difficult for the worker to carry out the planarization work while maintaining the trajectory of the runway by hand, and it is impossible to plan the work accurately. In addition to the excessive time taken by the measurement and post-processing, there is a problem that the work efficiency is very low.

Accordingly, an object of the present invention is to solve the above problems, by pressing and vibrating the upper surface of the traveling road concrete while traveling in the guide track to minimize the voids of the concrete, effectively flattening the track while maintaining the track It is to provide a driving path vibrator for guided-track rubber wheel light rail, which enables the operation.

In order to achieve the above object, the present invention, the main body is provided with one or more rollers on the side so as to operate in the guide track, and is installed on the bottom surface of the main body as well as on the upper surface of the runway concrete And a vibration means configured to vibrate the pressure roller to reduce the voids in the concrete by vibrating the pressure roller.

As described above, the present invention can not only minimize the air gap but also maintain the trajectory of the runway by compacting the upper surface of the runway concrete that is poured while driving on the guide track installed on the vertical wall of the roadbed after constructing the track of light rail. In this way, the process of light rail track construction and measurement are simplified, so the construction period of the light rail can be shortened and the construction accuracy of the track can be improved.

1 and 2 are a perspective view and a front view showing a driving path vibrator of a guide-track rubber wheel light rail according to the present invention, one or more rollers (1) is installed on the side so as to be able to travel in the guide track 54 In addition to the main body 2 and the lower surface of the main body 2 described above, the pressure roller 3 installed so as to travel while rolling on the upper surface of the traveling path concrete CT, and the pressure roller described above ( 3) by vibrating to a certain width to press the concrete (CT) consists of a vibration means configured to reduce the voids in the concrete.

That is, when the vibrating means vibrates at a predetermined pitch, it is possible to reduce the voids in the concrete (CT) while being pressed and vibrated while the poured traveling path (CT) is pressed.

Of course, since the main body 2 is still moving on the guide track 54 even when the pressure roller 3 travels while vibrating, the upper surface of the traveling path concrete CT tracks the track of the guide track 54. It is possible to maintain the same state as.

1 and 3, the vibrating means is installed between the pressure roller 3 and the main body 2, as well as the solenoid 4 configured to vibrate by an electric field when a constant frequency current is supplied. It consists of, the solenoid (4) by the pressure roller (3) is to cause the vibration at a constant pitch.

Here, the above-described solenoid 4 is a general one used to generate vibration, and its configuration and operation will not be described in detail. In addition, the effects are similar when using components commonly used to generate vibration.

Fig. 4 is a sectional view showing another embodiment of the vibration means, for example, an eccentric motor (a motor having a weight added to be eccentric to the shaft of the motor to generate vibration when rotating) is installed in the pressure roller 3, for example. If possible, a simpler configuration may also cause vibration.

In addition, between the main body 2 and the pressure roller 3 is provided with a sliding means for adjusting the width direction of the pressure roller 3, which is installed on the main body 2 in the left and right width direction rail (6) and the roller (7) is provided not only to move on the rail (6), but also to the bracket (8) connected to the upper portion of the solenoid (4) and to rotate the roller (7). It consists of the motor 9 provided in the bracket 8.

Of course, the switch S for operating the motor 9 and the solenoid (eccentric motor) 4 is provided in the main body (2).

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 muscles 56 according to the drawings for installing the back muscles of the traveling path 52, the traveling path 52 is constructed, and the rollers 1 of the body 2 are described above. ) Is mounted on the guide track 54 so as to be able to travel.

When the main body 2 is seated on the guide track 54, the worker installs the formwork C around the back muscle 56, and then casts the concrete. When the casting of the concrete is completed, the main body ( 2) is moved to the upper surface of the concrete (CT).

When the concrete CT hardens to a certain degree, the pressure roller 3 of the main body 2 is brought into close contact with the upper surface of the concrete CT, and in this state, the switch S is operated to cause the solenoid 4 to vibrate at a predetermined pitch. To do that.

When the solenoid 4 vibrates, the pressure roller 3 vibrates while moving up and down. When the pressure roller 3 vibrates in close contact with the surface of the concrete CT, the concrete is compacted. .

When the main body 2 is moved at a constant speed while the concrete CT is compacted by the vibration of the pressure roller 3, the pressure roller 3 moves while compacting the concrete CT. Bar, it is possible to effectively flatten the concrete of the runway.

Of course, when the eccentric motor 5 is used, the entire pressurized roller 3 vibrates in the front, rear, left, and right directions, thereby compacting the concrete CT.

When the pressurized roller 3 runs while compacting the concrete CT, the voids existing in the concrete CT are greatly reduced, and the strength of the traveling road concrete CT and the bonding force with the back muscle 56 may be reduced. Very excellent.

Here, since the main body 2 travels on the guide track 54 even when the flattening operation of the traveling concrete is performed by the pressure roller 3, the surface track of the flattened traveling track is further guided. It is easier to match the trajectory of.
