Description

[Detailed description of the invention] The present invention is a bogie traction device that prevents the rope that pulls the bogie from floating when the bogie transfers to a transfer rail that is connected to the traveling rail at a required slope. Regarding.

In recent years, as a method of concrete placement for dams, etc.
As shown in Figure 1, a running rail 1 laid on a slope
The hotpast station 2 can be raised along the concrete placement level, and the hotpast station 2 can be raised as the concrete placement level rises, and even if the concrete placement level changes, the hotpast station 2 can be raised to the dump truck 3, etc. 2, and the supply of concrete to the hotspa station 2 is carried out by a bucket cart 5 that runs on the traveling rail 1 and the transfer rail 4 provided at the hotspastion station 2. There is.

In such a method, since the running rail 1 and the transfer rail 4 have different slopes, the rope 6 for pulling the bucket cart 5 floats up while the bucket cart 5 is transferred to the transfer station 2.

Therefore, the pulling angle of the rope 6 with respect to the bucket cart 5 changes depending on the position of the bucket cart 5, and the rope 6 is bent at the engagement position of the bucket cart 5, and furthermore, it is likely to cause shaking at the floating part. There is a risk of wire breakage at the connection point. In addition, since a force is applied in the direction of pulling up the bucket truck 5 due to the weight of the rope 6, problems such as the bucket truck 5 moving due to changes in the weight of the bucket truck 5 (gradually moving when discharging concrete) occur. It was hot.

The present invention has been made with the aim of eliminating such problems, by providing guide rollers at points where the gradient changes so that the towing rope can be roughly aligned with the rail, and by taking care to ensure that the guide rollers do not interfere with the movement of the bucket cart.

Embodiments of the present invention will be described below based on the drawings.

Roller support stands 8, 8 are provided protrudingly from the leading end of the frame 7 of the hotspa station 2 on the running rail 1 side.
Further, the roller support stands 8, 8 are arranged parallel to the transfer rail 4, respectively, at intervals that do not interfere with the passage of the equalizer 9 of the bucket cart 5. A required number (5 in this embodiment) of guide rollers 11 are installed inside the roller support stands 8, 8 via shafts 10, respectively.
to be pivoted. Here, the pivot position of each roller 11 is arranged on a virtual arc of a required curvature so as to be substantially in contact with the traveling rail 1 and the transfer rail 4. Further, the equalizer 9 is installed at a position a required distance lower than the lower surface of the bucket cart 5 so as to be able to pass under each roller 11 without interfering with the rollers 11, and the ropes 6, 6 are connected to guides on both sides. roller 11,1
1, and the engagement position passes directly under the guide rollers 11, 11 on both sides.

Next, the operation will be explained.

The bucket cart 5 descending from above eventually transfers to the hot pass station 2, and the equalizer 9 passes below the guide rollers 11, 11 on both sides. In this state, the rope 6 is still attached to the guide rollers 11, 11.
not engaged with. When the bucket truck 5 further descends, the rope 6 rises slightly above the rail like the string of a bow and engages with each guide roller 11, preventing it from rising any further. Since each guide roller 11 is arranged in an arc shape with a required radius, the rope 6 can be bent along the rails 1 and 4 within a range that is not affected by its life.

Moreover, since each of the guide rollers 11 is provided on the hopper station side, even if the hopper station moves, the function of preventing the rope 6 from floating is not impaired in any way.

Although the above embodiment is a case in which the present invention is applied to equipment related to concrete placement where the Hotspa Station moves, it is of course possible to implement the invention to any type of towing of a trolley running on a running road with a changing slope. It goes without saying that various changes can be made without departing from the gist of the present invention, such as increasing the diameter of the guide roller 11 and having only one guide roller on each side, if there is space available.

As described above, according to the present invention, it is possible to prevent the towing rope from floating up, thereby preventing breakage of the rope at the connection point and movement of the truck due to changes in weight.

Claims (1)

[Scope of utility model registration request] In a bogie traction device for a bogie that runs on a road with a changing slope, an equalizer is installed on the underside of the bogie at a required distance below the bottom surface of the bogie, and ropes for pulling the bogie are attached to both width ends of the equalizer. In addition, roller supports are provided facing each other at locations where the slope of the running path changes so that the equalizer can pass therethrough, and guide rollers are installed on the running path so that the rope can be guided inside the roller supports and above the position where the equalizer passes. A trolley traction device characterized in that a plurality of devices are provided along.
