Abstract

(57) [Summary] [Purpose] By attaching a drilling machine to a hydraulic excavator and mechanizing it, 1) scaffold construction work is unnecessary and the construction period can be greatly shortened. 2) scaffold construction work is unnecessary. To be able to significantly reduce construction equipment costs, 3) To be able to significantly reduce labor costs due to lack of scaffolding (labor),
4) To provide a punching machine for pile driving capable of ensuring the safety of workers by preventing a fall from a scaffold. [Structure] Base beam 2, second beam 5 and arm
In a hydraulic excavator provided with a multi-stage attachment such as a frame 7, etc., the perforator 10 is attached to the tip of the hydraulic excavator to enable perforation work both on a flat surface and on an inclined surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a punching machine for driving foundation piles.

[0002]

[Prior Art]

 In the past, several workers guided and operated a drilling machine suspended by cranes on a scaffolding that was erected to drill a concrete anchor anchor into the ground. For this reason, it is necessary for the piercing worker to erection and remove the scaffolding, and the contractor has had problems such as securing scaffolding construction, increasing scaffolding construction costs, and extending construction period. Furthermore, there were many fears that a worker engaged in perforation work might fall from the scaffolding that was erected, or could be involved in a personal injury such as a fall of the perforator.

[0003]

[Problems to be solved by the device]

 Conventionally, drilling holes for concrete anchors during grouting (concrete dirt excavation), which is one of the steps of dam construction, has been done manually with a scaffold. But, as above, there were many problems. The present invention attaches a drilling machine to a hydraulic excavator and mechanizes it. 1) It eliminates the need for scaffold erection work and significantly shortens the construction period. 2) Does not require scaffold erection work, resulting in significant construction equipment costs. Such as 3) reduction, 3) significant reduction of labor costs due to shortage of scaffolding (labor), 4) ensuring worker safety by preventing fall from scaffolding, etc. It is intended to provide a possible drilling machine for pile driving.

[0004]

[Means for Solving the Problems]

 A drilling machine was attached to the tip of a hydraulic excavator equipped with a multi-stage attachment to enable drilling work both on a flat surface and a slope.

【Example】

 A description will be given based on the figure. Fig. 1 shows the appearance of the machine in the backhoe (two-stage attachment) state, and Fig. 2 shows the appearance of the machine in the high-altitude crusher (three-stage attachment) state. 1 and 2, 1 is a hydraulic excavator body, 2 is a base boom, and 3 is a base boom cylinder. Reference numeral 4 is a second boom cylinder, and 5 is a second boom. 6 is an arm cylinder, and 7 is an arm. 8 is a bucket cylinder, 9 is a bucket linkage, and 10 is a perforator.

An attachment, that is, an attachment, that is, a base boom 2 and an arm 7 operably mounted on the hydraulic excavator main body 1 by a base boom cylinder 3 and an arm cylinder 6, is a bucket linkage at the front ends thereof. A perforator 10 that follows the operation of the bucket cylinder 8 via a hole 9 is mounted.

Alternatively, as shown in FIG. 2, an attachment, that is, a base boom 2, a second boom 5, and an arm 7 operably mounted by a base boom cylinder 3, a second boom cylinder 4, and an arm cylinder 6. A drilling machine 10 that follows the operation of the bucket cylinder 8 via a bucket linkage 9 is attached to the tip. By operating these multiple cylinders 3, 4, 6, 8, all kinds of drilling angles can be set, and as shown in FIG. 3, it is not necessary to drill on the flat surface 11 as well as the slope lower 12 and slope upper 13 and the drilling surface. A wide range of drilling work is possible.

[0008]

[Application example]

 Although the pile driving machine has been described above, it can be applied to retaining wall construction (collapse prevention) in mountainous areas.

[0009]

【effect】

 Compared to the conventional construction method that relied on a lot of human power, a drilling machine (drill, etc.) was attached to the tip of the multi-stage bending type attachment of the hydraulic excavator, and by mechanizing the drilling work, there was one operator and one working machine. It is now possible for two operators to perform drilling work safely from the ground by using either one or a separate aerial work vehicle.

Further, even if the punching machine is mounted around the work table of the existing refractable aerial work vehicle, the same working effect as that of the present invention can be obtained. Furthermore, by using the concrete pump together, it is possible to perform grouting (concrete hitting) with one machine.
