Description

The present invention relates to a construction work device used for construction of a bridge or a highway, and more particularly to an overhead crane device or a bridge crane device.

  In general, an overhead crane device or a bridge crane device used outdoors is provided with legs at both ends of a crane girder, a traveling saddle is attached to the lower part of the legs, and the pair of cranes on the traveling track provided on the ground or on the floor. In general, a traveling saddle attached to the leg of the vehicle is placed so that the overhead crane device or the bridge crane device itself travels on the traveling track.

  In general, the overhead crane device or the bridge crane device is generally installed outdoors, and some cantileveres are provided outside the traveling track in order to expand the work range.

  By the way, a conventional pair of traveling tracks is formed with parallel equal intervals, and the overhead crane device or the bridge crane device travels on the pair of parallel traveling tracks with the parallel intervals. What did do was normal.

  However, as shown in FIG. 1 and the like, conventionally, for example, due to the construction site for constructing a highway, for example, one side of an up-and-down line, an expressway traveling toward an up-line, and the opposite of the up-and-down line There are relatively many highways that are built with a gap between them and the highway that runs toward the down line.

  In other words, conventionally, on an elevated road such as an expressway, a viaduct beam is constructed separately for each of the upper and lower lines, and an expressway is constructed on that, or a vertical line is created with a gap on one viaduct beam. Often built separately. Therefore, there are many situations in which the vertical lines are separated and a gap is formed in the central separation zone.

  Here, if a vehicle passes over a vertical viaduct or a windy weather condition, ups and downs may occur in each lane due to the vibration. Due to the ups and downs, a level difference may occur between the upper and lower roads in the gap portion of the central separation zone.

  Moreover, in such an elevated road, rainwater invaded through the gap in the central separation zone, causing corrosion of concrete and internal steel frames, and also causing a problem of rain leakage under the elevated road.

  In order to prevent this rain leakage, conventionally, measures have been taken, such as catching rain by providing a drainage channel such as a dredge along the gap below the elevated road.

  Furthermore, there was a risk that a vehicle, luggage, or the like would fall in the gap.

  Therefore, in order to solve the above various problems, not only the viaduct beam central separation zone part is shielded, but particularly during such highway renovation work, the viaduct beam central separation zone part is blocked to widen the road part. Widening work has been requested.

However, the conventional overhead crane device or bridge crane device is designed on the assumption that it works by traveling on a pair of traveling tracks formed with parallel equal intervals as described above. For example, it is not designed to be used when the distance between a pair of traveling tracks as shown in FIG. 1 is widened or narrowed.

JP 2004-175545 A

Thus, the present invention has been devised in order to solve the above-described conventional problems. For example, the distance between the pair of traveling tracks does not include a constant parallel equal interval. Even if the distance between the two is widened or narrowed, an erection work device such as an overhead crane device or a bridge crane device that can run smoothly on the pair of traveling tracks can be operated. It is intended to provide.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  FIG. 1 is a schematic plan view showing a state in which there is a gap 4 between the up line 2 and the down line 3 of the expressway 1, and the gap 4 is not parallel in the width interval, and the width interval is not parallel. There are widened and narrowed areas.

  Then, the gap 4 is closed and the expressway is expanded. At this time, the crane device 14 of the present invention, that is, the construction work device is used.

  The construction of the construction work device according to the present invention will be described with reference to FIGS.

  2 and 3, reference numeral 5 denotes a side wall that is built up and constructed from both ends in the width direction of the up line 2 and down line 3 of the highway 1.

  For example, the upper surfaces of the side walls 5 and 5 adjacent to the up line 2 and the down line 3 serve as a travel path, and a pair of travel tracks 6 and 6 are installed on the travel path.

  A pair of traveling saddles 8, 8 having wheels 7, 7 on both ends in the longitudinal direction are movably installed on the pair of traveling tracks 6, 6, and on the pair of traveling saddles 8, 8. A pair of connecting girders 9 and 9 formed shorter than the traveling saddle 8 is placed. That is, this means that the length of the traveling saddle 8 is preferably longer than the length of the connecting girder 9. This is to improve the stability of the apparatus.

  The traveling saddle 8 and the connecting girder 9 are, for example, at a substantially central position in the longitudinal direction of the traveling saddle 8 and a substantially central position in the longitudinal direction of the connecting girder 9. It is connected by a rotating connecting member 10 so that it can be freely (see FIG. 1).

Further, as can be understood from FIG. 4, the pair of connecting girders 9 and 9 are connected to the pair of crane main girders 11 and 11 and are framed in a substantially rectangular shape, and constitute a base part of the crane mount 12. A base 13 is formed.
As described above, the gantry base 13 is framed in a substantially rectangular shape, but the frame is firmly connected, and the outer shape of the gantry base 13 having a substantially rectangular shape is not deformed. Therefore, as a matter of course, the length between the connecting portions of the pair of crane main beams 11, 11 to which the pair of connecting beams are connected, that is, the length in the longitudinal direction does not change.

  And this means that the width interval is not parallel, and the unloading tool such as a crane device 14 which will be described later is directed in the longitudinal direction on the gap 4 where the width interval is wide or narrow. Means that the crane width formed between the pair of crane main girders 11 and 11 does not change and remains unchanged. Therefore, as will be described later, when the vehicle travels in a narrow space of the gap 4, as shown in FIG.

  Thus, a lifting tool such as the crane device 14 is installed on the crane mount 12 thus configured.

  As can be understood from FIG. 2, wheels 26 and 26 are provided at the lower portion of the crane device 14 so as to move and travel in the longitudinal direction on the pair of crane main girders 11 and 11. Thus, the crane device 14 is configured to be able to move and travel also in the width direction of the gap 4.

Incidentally, as shown in FIGS. 3 and 4, each of the pair of connecting beams 9, 9 is provided with at least two auxiliary beam devices 15. The auxiliary beam device 15 includes:
Auxiliary support beam 16 that is attached so that one end side thereof is rotatable so as to project outward from the connecting beam 9 and a fixing member 17 that holds and fixes the auxiliary support beam 16 that projects outward in that state are provided. Has been.

  Here, with reference to FIG. 1, the movement of the erection work device according to the present invention will be schematically described. A pair of traveling saddles 8, 8 constituting the erection work device of the present invention on the pair of traveling tracks 6, 6. Are installed so that the construction work device of the present invention moves on the pair of running tracks 8 and 8 so that the work can be performed.

  Therefore, in FIG. 1, the distance between the pair of traveling tracks 6 and 6 is narrower than the length of the erection work device, so that the erection work device can move even when it is inclined with respect to the travel tracks 6 and 6. It is configured.

  That is, the pair of traveling saddles 8 and 8 usually travel in parallel on the pair of traveling tracks 6 and 6, but the pair of connecting girders 9 and 9 are located at the longitudinal center positions of the traveling saddles 8 and 8. Since the pair of traveling saddles 8 and 8 are connected to the pair of traveling saddles 8 and 8 by the rotation connecting member 10 so as to be horizontally rotatable, a pair of traveling tracks are inclined while the construction work device itself is inclined with the rotation connecting member 10 as a rotation axis. It moves on the 6th and 6th.

  However, at that time, if the erection work device becomes too slanted, stable traveling on the pair of traveling tracks 6 and 6 is impossible.

  That is, as understood from FIG. 6, when the tilting is excessively inclined, the crane mount 12 framed in a substantially rectangular shape by the pair of connecting girders 9 and 9 and the pair of crane main girders 11 and 11 is stably formed. It will not be placed on the pair of traveling tracks 6 and 6. This is because the two opposite corners 18 and 18 of the crane gantry 12 framed in a rectangular shape are disengaged from the traveling tracks 6 and 6, and traveling stability is extremely lowered.

  Therefore, in the present invention, in order to solve the above-described situation, as can be understood from FIG. 1, the traveling saddle protrudes outward from the connecting beams 9, 9 on both ends in the longitudinal direction of the pair of connecting beams 9, 9. Auxiliary beam devices 15 and 15 having auxiliary support beams 16 extending on the upper and lower sides of the traveling saddles 8 and 8 are attached.

  Here, the configuration of the auxiliary beam device 15 will be described with reference to FIG. 4. The auxiliary beam device 15 includes an auxiliary support beam 16 and a fixing member 17 that fixes the auxiliary support beam 16. Yes. One end of the auxiliary support beam 16 is pivotally supported at the end of the connecting beam 9, and the auxiliary support beam 16 is configured to be rotatable so as to project outside the connecting beam 9 with the shaft support 19 serving as a fulcrum.

  As shown in FIGS. 1 and 4, the auxiliary support beam 16 protruding outward is configured to extend on the traveling saddle 8 and to contact the upper surface of the traveling saddle 8.

  In addition, when the auxiliary support beam 16 rotates and protrudes outward, the auxiliary support beam 16 is firmly fixed by the fixing member 17 so as not to swing while maintaining the extended state.

  Therefore, as shown in FIG. 1, even if the construction work device of the present invention travels obliquely on the pair of travel tracks 6 and 6, the auxiliary support beam 16 is located on the upper surface of the travel saddle 8. Therefore, it is supported on the traveling saddle 8 in at least three places (A, B, C shown in FIG. 1). Therefore, the erection work device of the present invention never brings about an unstable traveling state.

  By the way, as shown in FIG. 1, in order to stably run the construction work device on the pair of traveling tracks 6, 6 by tilting the construction work device, the movement of the wheels 7 that travel on the traveling tracks 6, 6 is moved. You must control the speed (rotation speed).

  Referring to FIG. 1, in the case of the X position and the Y position, the position of the traveling saddle 8 on the down line side must move further. This is because the erection work device must be made more oblique. For this reason, the moving speed (rotational speed) of the wheel 7 of the traveling saddle 8 located on the down line side needs to be higher than the moving speed of the wheel 7 of the traveling saddle 8 located on the up line side.

  In addition, the construction work in the case of the X position and the Y position is made by making the moving speed of the wheel 7 of the traveling saddle 8 located on the up line side slower than the moving speed of the wheel 7 of the traveling saddle 8 located on the down line side. You may acquire the tilt of the device.

  Furthermore, at the Z position, the moving speed (rotational speed) of the wheel 7 of the traveling saddle 8 located on the down line side must be made faster than the moving speed of the wheel 7 of the traveling saddle 8 located on the up line side.

  Here, the control relating to the moving speed of the wheel 7 of the traveling saddle 8 located on the up line side and the moving speed of the wheel 7 of the traveling saddle 8 located on the down line side is, for example, the control of the control panel 22 shown in FIG. Is done by.

  For example, the necessary inclination angle of the construction work device is continuously detected during traveling, and the moving speed (rotational speed) of the wheels 7 traveling on the respective traveling tracks 6 and 6 is calculated based on the detected values. ing. For example, as can be understood from FIG. 4, the generator 23 and the control panel 22 are installed on the corridor 24, and the construction work device in which the moving speed (rotational speed) of each wheel 7 is detected by the control panel 22. This is calculated from the required inclination angle, but the configuration is adopted.

Referring to FIG. 7, the control panel 22 is provided with a device inclination detecting unit 27, a wheel rotation speed calculating unit 28, a wheel motor control unit 29, and the like. When the inclination is detected, the information (inclination detection value) is sent to the wheel rotation speed calculation unit 28.
The wheel rotation speed calculation unit 28 calculates the moving speed (rotation speed) of each of the wheels 7 attached to both ends of the traveling saddle 8 based on the detected value.

Then, the calculated moving speed (rotational speed) of the wheel 7 is sent to the wheel motor control unit 29.
The wheel motor control unit 29 controls the wheels 7 and 7 based on the movement speed (rotational speed) of each wheel 7 sent out.

  Further, as understood from FIGS. 2 and 3, the present apparatus is provided with the anti-derailing device 20 from both sides of the wheel 7 toward the traveling track 6, so that each wheel 7 is not derailed. Thus, the safety of the device is contemplated. As is understood from FIG. 3, a guide roller 30 is provided on the front side of the wheel 7. For example, when the traveling track 6 changes from a so-called linear track to a skewed or curved track, The roller 7 hits the side surface of the traveling track 6 so that the direction of travel of the wheel 7 can be guided.

The walkway 24 is provided on both sides of the gantry base 13, and the walkway 24 is secured as a work space. Here, the code | symbol 25 is a handrail, and the code | symbol 21 shows an alarm light (refer FIG. 3).
