Abstract

(57) [Summary] [PROBLEMS] A rock drill for drilling a water holding hole for vegetation on a slope, with the aim of improving safety and workability. A large rocking triangle is formed by extending and extending a handle of a conventional rock drill and connecting two low lip ropes to the left and right of the handle and connecting the rope to a parent rope. As a result, stability is maintained, and the vibration during work is absorbed by the master rope from the low lip rope.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a rock drill that is modified and used for drilling a water retention hole on a slope.

[0002]

[Prior art]

 Drilling of water retention holes formed on the slopes for greening of the slopes is performed using palm drills, electric drills, or ordinary rock drills.

[0003]

[Problems to be solved by the invention]

 However, the construction site was a sloped concrete spraying site, and because of the slope and height, such conventional tools were dangerous and inefficient.

[0004]

[Means for Solving the Problems]

 The inventor worked on this work for many years and made various trial improvements in order to improve his own safety and work efficiency, and arrived at the present invention.The present invention improved the rock drill with good operability. In addition, even on a slope with a slope and a high slope, work can be performed in a well-balanced, safe, and efficient manner with a single parent rope.

[0005] This is made by a low rip rope and a main rope attached to the left and right sides of the handle by extending the handle of a conventionally used rock drill having a length of about 350 m / m to 500 m / m. The triangles with a wide base provide strength to the arms to maintain a stable balance, and the vibrations during drilling are absorbed by the new handle from the handlebar and are not transmitted directly to the worker's body, making work easier. This is probably because

Further, by covering the low lip rope with a vinyl tube, it is possible to prevent the sliding of the low lip rope by the concrete surface during the drilling operation or during the movement, thereby ensuring safety.

【Example】

 In FIG. 1, A is a rock drill, and the improved rock drill A of the present invention is constructed by extending the length of the handle (2) to l compared to the handle length l of the conventional rock drill. You.

This length is expressed as a numerical value, l = 350 m / m, l = 500 m / m, and the low lip rope (3) is fixed to the left and right of the handle (2) by the gripping tool (4). . The two low lip ropes (3) are connected to a parent rope (lifeline) B descending from above by a connection fitting (5).

Reference numeral (1) denotes a pit of a rock drilling machine A, and an operator grips a handle (2) via a safety belt and the slope is suspended by a master rope B as shown in the embodiment of FIG. The drill is performed while drilling.

As shown in FIG. 1, the drilling machine A of the present invention applies force to the arm by a wide base triangle formed by the handle (2), the low lip rope (3) and the main rope B. When the slope is moved to the left or right while holding the handle (2), the handle length is longer than the conventional handle length l, so there is stability and the pit (1) of the rock drill is applied at right angles to the slope. Drilling can be performed easily and efficiently. With this configuration, the vibration during work is absorbed by the master rope B from the low lip rope (3).

The low lip rope (3) can be prevented from being cut due to wear of the rope (3) by being covered with a vinyl tube (3-1) as shown in FIG.

[0013]

[Effect of the invention]

 The rock drill A of the present invention has a stable balance by increasing the length of the handle of the conventional rock drill and thereby increasing the base of the triangle formed by the handle and the two low lip ropes. The low lip rope is covered with a vinyl tube to prevent cutting due to abrasion of the low lip rope, so drilling work can be performed efficiently with a stable posture on the slope It has an outstanding effect.
