Abstract

The present invention relates to a leader slider of an excavator including a base bracket, a sliding shoe and a finishing plate. The base bracket is fixed to a drill head or a boom. The sliding shoe is made of a synthetic resin material, is fixed to the base bracket, slides in a state where it comes into contact with a rail part of a leader, and has a dented guide band groove which receives and guides the rail part or is guided. The finishing plate is fixed to the sliding shoe and has a jaw to prevent separation of the rail part. According to the present invention, because the sliding shoe made of the synthetic resin material absorbs vibration and shock of the excavator, it reduces abrasion of a sliding part. Even though sands or gravels in a workspace are attached to the rail part of the leader and the leader slides along a support part of the boom or the drill head slides along the leader, because the sliding shoe made of the synthetic resin material is first abraded, the leader slider is easy to be replaced and reduces repairing costs and replacement costs.

Description

Slider for leader of Excavator < RTI ID = 0.0 >

The present invention relates to a reader slider of a perforator, and more particularly, to a reader slider of a perforator that slides along a leader of a perforator and is mounted on a drill head or a boom supporting a leader of a perforator, .

Generally, perforator is a device for excavating the deep hole penetrating from the ground to the ground for drilling work, soil inspection, groundwater development and so on.

A perforator is disclosed in Korean Patent No. 0624233, Korean Patent No. 0916667, and the like.

1, a conventional perforator includes a main body 10 provided with a driving device such as an engine, a reader 20 supported by the main body 10 and having a predetermined length, A rod 40 connected to the drill head 30 to be lifted or lowered by the drill head 30 and a rod 40 connected to the drill head 30 so as to move up and down by the drill head 30, And a drilling unit 50 provided at the tip of the rod 40 for excavating the ground by being raised or lowered together with the rod 40.

The main body 10 is provided with a boom 60 for supporting the leader 20 and the installation height of the leader 20 is adjusted by the hydraulic cylinder coupled to the boom 60. A rail portion is formed in the leader 20 so that the leader 20 slides along the support portion of the boom 60 by the hydraulic cylinder while the drill head 30 slides along the leader 20 by the chain.

The excavation unit 50 is composed of a bit excavated by hitting the ground and a hammer operated by hydraulic pressure to give a hitting force by the bit. And a separate hydraulic line for transferring the hydraulic pressure to the digging unit is installed.

The drill bit is rotated or drilled to a certain depth by striking the ground. As the ground is excavated, the excavation unit 50 and the rod 40 are drawn into the ground. The length of the rod is extended by connecting the rod by the depth at which the digging unit 50 and the rod 40 are drawn into the ground.

A load clamp 70 is provided at an end of the reader 20 near the ground to support the rod 40 to which the digging unit 50 is connected. The process of joining the rods is the process of pulling into the ground with the drilling unit to separate the drill head from the rod gripped by the rod clamp, then coupling the new rod to the drill head and coupling it to the rod gripped by the rod clamp .

The sand or gravel of the work site is attached to the rail 20 of the drilling machine so that the drill head 30 slides along the leader 20 while the drill 20 is sliding along the support of the boom 60 The sliding portion is damaged and easily abraded, which causes a problem that the repair replacement cost is increased.

In addition, the drill has a problem in that vibration and impact are severe during the drilling operation, but the sliding portion does not absorb vibration and impact, thereby further promoting wear of the sliding portion.

It is an object of the present invention to provide a perforator which is slidably coupled to a reader to easily absorb vibrations and impacts to reduce wear and facilitate repair replacement at the time of wear, And a reader slider.

According to an aspect of the present invention, there is provided a lead slider of a perforator mounted on a drill head, the base slider including a base bracket fixed to the drill head, A sliding shoe of a synthetic resin material which is fixed and slides in close contact with a rail portion, and a finishing plate which is fixed to the sliding shoe and forms a jaw to prevent a deviation of the rail portion; The sliding shoe is provided with a recessed guide groove for guiding and receiving a rail portion.

The base bracket is in the form of a plate having a reinforcing protrusion, the sliding shoe is in the form of a plate having a concave guide groove, and the finish plate is in the form of a strip fixed on both sides in the width direction of the sliding shoe.

The synthetic resin material is preferably a polyurethane material.

The lead slider of the perforator according to another embodiment of the present invention is a lead slider of a perforator mounted on a boom for supporting a leader having a rail portion formed therein. The lead slider includes a base bracket fixed to the boom, And a finishing plate which is fixed to the sliding shoe and forms a jaw for preventing the departure of the rail portion; The sliding shoes are provided with grooved grooves for receiving and guiding the rail portion.

The base bracket includes a base plate portion fixed to the boom, a base plate portion to which the sliding shoe is fixed, and a connecting rod connecting the base plate portion and the base plate portion. The sliding shoe is in the form of a plate having a concave guide groove groove, Are in the form of strips fixed on both sides in the width direction of the sliding shoes.

According to the reader slider of the perforator according to the present invention, since the sliding shoe made of synthetic resin absorbs the vibration and shock of the perforator, the wear of the sliding portion is reduced and the sand or gravel of the work site is attached to the rail portion of the reader, Even if the drill head slides along the support or slides along the leader, the sliding shoe of the synthetic resin material is worn first, so that the repair replacement work is easy and the repair replacement cost is reduced.
