Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slope carrier device for mounting a drilling device, for example, to drill from the slope toward the ground, or to transport equipment or materials to a high place or a low place along the slope.
[0002]
[Prior art]
Conventionally, in slope stabilization work and slope protection work, in order to reinforce natural ground and cut slopes, drilling is performed from the slope to the ground, and steel bars such as reinforcing bars and rock bolts are used for this drilling. , And filling the surrounding with grout material to integrate with the natural ground, reduce the earth pressure, improve the stability of the slope, increase the bearing capacity, Slope stabilization method that fixes structures such as frame to anchor with slope, and also assembles a crimped wire mesh along the slope, or carries a pre-assembled unit in factory production to the site and install it on the slope After building the formwork, the legal form is constructed by spraying mortar into the formwork while burying and killing the crimp wire mesh formwork. Such as anchor combination method frame construction method to fix the mountain has been actively carried out.
[0003]
In this type of slope or slope construction, when drilling toward the natural ground is required, a ground platform (slipping scaffold) or a work platform using a single pipe or H-shaped steel is installed on the slope. However, a drilling device was installed on this work platform to perform drilling work.
[0004]
[Problems to be solved by the invention]
However, when performing a drilling work by installing a work platform on a slope, in order to install the drilling device on the work platform, or to perform subsequent refilling and movement, a truck crane, a crawler crane, etc. The condition is that the boom can be reached, but the occupancy of these heavy machinery becomes a problem at this time. In other words, slope stabilization works and slope works are done in places where it is relatively difficult to secure yard or yard, such as in mountainous areas, and even if it is possible to occupy some general roads, In the middle, a part of the road is occupied by the heavy machinery, and there is a problem that a traffic trouble occurs. In addition, when the slope height is large, a large heavy machine having a large capacity is required, so that there is a problem that the construction cost accompanying the construction of the lock bolt or the ground anchor increases.
[0005]
In recent years, in view of the above-mentioned problems, as a method for safely and efficiently drilling from a slope, Japanese Patent Application Laid-Open No. 11-30089 discloses that pipes are arranged in a grid pattern in the vertical and horizontal directions on the slope. Further, there is disclosed a drilling method and an apparatus therefor for performing a drilling operation by a drilling device that is moved while sliding on the pipe scaffold in a sled form. However, the pipe scaffold has a predetermined length. The scaffolding pipes are constructed while being connected to each other by clamps, and the clamps protrude upward from the upper surface of the pipes, so the drilling device cannot actually slide smoothly. There was a problem.
[0006]
On the other hand, in the above-mentioned method of frame construction represented by the free frame method, etc., when the inclination angle is tight, it is not possible to carry the construction machine directly on the slope, so from the formwork construction to reinforcement and mortar spraying In addition to all the work, it was in a situation where it was necessary to rely on human power to carry the materials placed on the flat to the construction site.
[0007]
Accordingly, the main problem of the present invention is to provide a slope carrier device that can be smoothly run along a pipe installed on a slope while passing over a pipe coupling clamp. The purpose of this work is to reduce the labor on the slope as a carrier for transporting equipment and materials in slope construction such as construction of a frame, as well as to enable efficient drilling work by installing the device.
[0008]
[Means for Solving the Problems]
The present invention for solving the above-mentioned problems is a carrier device for slopes that can run along pipes installed on slopes,
The slope carrier device has a pair of pipes arranged in parallel as a running rail, and is supported by a wheel running on the upper surface of the pipe, and the wheel is on a circular locus drawn around a rotation support shaft. A plurality of rollers are arranged along the circumferential direction, and a space is formed to avoid a collision with the clamps when overcoming the clamps connecting the pipes between the rollers. It is characterized by this.
[0009]
In this case, each of the rollers is supported by a roller support shaft longer than at least the width of the roller in order to prevent the wheel from being removed from the pipe, and is biased to one side of the roller support shaft by urging. It is desirable to be.
[0010]
In addition, on at least one side of the pair of pipes serving as running rails, on both sides of the pipe straddling the pipe in a plan view, the pipe side surface is a running surface, and on a circular locus drawn around the rotation support shaft. A plurality of rollers are arranged along the circumferential direction, and a guide wheel having a structure is formed in which a space is formed between the rollers to avoid collision with the clamps when climbing over the clamps connecting the pipes. It is desirable to install. By providing such a guide wheel, it is possible to completely prevent the wheel from being removed, and the guide wheel disposed above the pipe surely supports the component force in the slant direction of the carrier device's own weight. In this case, it is desirable that the guide wheel disposed in at least one region across the pipe in a plan view is urged and supported in the pipe contact direction. When climbing over the clamp, the carrier device for slopes is laterally shaken. However, by supporting the guide wheel in the direction of contact with the pipe, the lateral shake is absorbed to prevent wheel removal.
