Description

[Detailed description of the invention] This invention relates to a cable guiding cart for a trough that runs along a trough while holding the tip of the cable being laid in the trough in a state that is lifted above the floor of the trough. .

Generally, when the cable C is laid on the trough 1 in the tunnel 4 as shown in FIG. The receiver is configured to run and move on rollers, and the driving force for moving the cable C forward in the longitudinal direction of the trough 1 is given by electric rollers that are mixed and arranged in the receiver rollers, In addition, in order to prevent the tip of the cable from hanging downward due to its weight and colliding with the floor of the trough 1, making it impossible to lay the cable, the side edges 1a and lb of the trough 1 are used as guide rails. A moving cable leading cart is prepared, and the leading end of the cable C is held on the leading cart in a state where it is lifted above the floor surface of the trough 1.

However, in this case, in the upper and middle troughs 1 located far above the worker in the tunnel 4, the worker cannot monitor the cable installation status at all, so the engagement state between the cable and the receiving roller To avoid the possibility of derailment of the lead truck or the derailment of the leading bogie, and the occurrence of various accidents that would impair the smooth cable installation work due to the cable traveling on the trough 1 without being able to confirm the presence or absence of various obstacles. This created a serious problem in that it was impossible to do so.

The object of this invention is to provide a trough leading truck that eliminates the above-mentioned problems.

An embodiment of this invention will be described below with reference to FIG.

In the figure, reference numeral 2 designates a leading truck main body, which is composed of a horizontal plate-shaped portion 5 and vertical plate-shaped portions 6.7 extending downward on both sides thereof.

Wheels 8, 9 have engagement grooves 8a, 9a with the side edges 1a, lb of the trough 1 at the front and rear of the lower ends of each vertical plate-like portion 6, 7.
are attached, and each wheel 8, 9 is attached to the side edge 1a of the trough 1,
By being engaged with and guided by lb, the leading truck body 2
is made to travel along the trough 1.

One vertical plate-like part 6 and the other vertical plate-like part 7 have different heights corresponding to the side edges 1a and 1b of the trough 1, which have different heights, but this is different from the horizontal plate-like part. 5 is to be parallel to the floor surface of the trough 1.

Appropriate bolts 10 are installed on the upper surface of the horizontal plate-like portion 5 of the truck body 2, and a clamp plate 11 having a substantially semicircular cross section is tightened thereon by, for example, a wing nut 12. 13 are provided.

Thus, hook-shaped arm members 15A and 15B whose tips point downward are protruded from the front and rear portions of the upper part of one vertical plate-like portion 6 via base members 14A and 14B, respectively. , 15B has a swing connecting member 16A at its tip.
, 16B, front and rear monitoring mirrors 3A and 3B having convex reflective surfaces are attached.

Therefore, each of the monitoring mirrors 3A and 3B is swingable in any direction left and right, front and back, with its reflective surface facing downward.

In other words, the front monitoring mirror 3A can visually confirm the lower position of the leading bogie, the deployment status of the receiving rollers in the foreground of the leading bogie, the presence or absence of various obstacles, etc. due to the reflective action shown by the imaginary line A in FIG. Moreover, by adjusting the oscillation position, the viewing position in front of the leading bogie can be variably set as appropriate.Similarly, the rear monitoring mirror 3B has a reflective action as shown by the imaginary line B in FIG. It is possible to visually check the lower position of the cable C and the installation state of the cable C in the rear view of the leading truck, and by adjusting the oscillation position, the viewing position behind the leading truck can be variably set as appropriate.

In addition to the convex mirrors of the above-mentioned embodiments, concave mirrors or plane mirrors may be used as the monitoring mirrors 3A and 3B, if necessary.

According to this invention, since a monitoring mirror is attached to the main body of the leading trolley, the state of engagement between the cable and the receiving roller and the presence or absence of various obstacles can be monitored through the monitoring mirror regarding the trough located above the tunnel. Workers on the tunnel floor can easily monitor the cable, thereby preventing derailment of the leading truck and other accidents, and smoothly laying the cable in the trough.
