Abstract

A down-the-hole drill rod pad fork comprises a U-shaped fork head, wherein the bottom end of the U-shaped fork head is connected with one end of a handle, the other end of the handle is fixedly connected with a circular ring, a first safety hook is detachably connected with the circular ring, and the first safety hook is movably connected with a second safety hook through a safety rope; the handle is held, the first safety hook is buckled into the circular ring, the second safety hook is buckled on a scaffold or a drilling machine main body, then the U-shaped opening of the U-shaped fork head in the main body component is inserted into the notch of the drill rod locking joint, and when the drill rod is sleeved in the U-shaped opening of the U-shaped fork head in the main body component and the cushion fork is manually adjusted to a working position, the drill rod starts to be assembled and disassembled; the utility model has the advantages of simple structure, convenient installation, detachability, easy carrying, safety and reliability.

Description

Down-the-hole drill rod cushion fork

Technical Field

The utility model relates to a drilling appurtenance is administered to side slope, concretely relates to down-the-hole drill drilling rod pallet fork.

Background

The downhole drill rod pad fork is a tool for clamping and suspending a drill rod at a drilling hole when the drill rod is assembled and disassembled in the slope management construction, and when the drill rod is lifted, a fork hole of the pad fork is inserted into a notch of a drill rod lock joint, so that the drill rod can be suspended at the drilling hole, the safety of the drill rod is guaranteed, and meanwhile, the drill rod joint can be conveniently screwed down after being screwed down. The existing down-the-hole drill backing fork is driven by machinery when a drill rod is assembled and disassembled in the actual use process, so that huge vibration is easily generated, the backing fork falls off from a drilling tool, and then falls to the ground from a scaffold. The falling can generate huge potential safety hazards, and because the cushion fork has certain weight, people or buildings are easily injured by pounding in the falling process. Generally, the construction plane is located at a distance from the ground, and it takes a lot of time for an operator to retrieve the fork via the scaffold, and the work efficiency is affected.

Disclosure of Invention

In order to overcome the not enough of above-mentioned prior art, the utility model aims to provide a down-the-hole drill drilling rod pallet fork can prevent to fill up and drop from scaffold work plane in the fork use, also avoids the workman operation in-process because of filling up the fork lost time that drops, has simple structure, simple to operate, can dismantle, easily carry and safe and reliable's advantage.

In order to achieve the above object, the utility model discloses a technical scheme be:

the utility model provides a down-the-hole drill rod pallet fork, includes U-shaped

jaw

1, 1 bottom of U-shaped jaw is connected with the one end of handle 2, and the other end and the 3 fixed connection of ring of handle 2 can be dismantled with ring 3 and be connected with first safety hook 4, and first safety hook 4 passes through

safety rope

5 and 6 swing joint of second safety hook.

The thickness of the handle 2 is consistent with that of the U-shaped fork head 1, and the width of the handle 2 is smaller than that of the U-shaped fork head 1.

The detachable connection is a locking connection.

The movable connection is that two ends of the safety rope 5 are respectively connected with the first safety hook 4 and the second safety hook 6 into a whole through knots.

The utility model has the advantages that:

the first safety hook 4 is detachably connected with the circular ring 3 through a connecting component, and the second safety hook 6 is detachably connected with the scaffold, so that accidents caused by falling of the cushion fork from a working plane of the scaffold in the use process are prevented, the safety is greatly improved, the waste of time caused by falling of the cushion fork in the operation process of workers is also avoided, and the working benefit is improved; has the advantages of simple structure, convenient installation, detachability, easy carrying, safety and reliability.

Drawings

Fig. 1 is a perspective view of the present invention.

In the figure: 1. a U-shaped prong; 2. a handle; 3. a circular ring; 4. a first safety hook; 5. a safety cord; 6. and a second safety hook.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the cushion fork of the down-the-hole drill rod comprises a main body component, a connecting component and a safety component, wherein the main body component comprises a U-shaped fork head 1, and the bottom end of the U-shaped fork head 1 is connected with one end of a handle 2; the connecting component comprises a circular ring 3, and the circular ring 3 is fixedly connected with the other end of the handle 2; the safety component comprises a first safety hook 4 detachably connected with the circular ring 3, and the first safety hook 4 is movably connected with a second safety hook 6 through a safety rope 5.

The detachable connection is a locking connection.

The utility model discloses a theory of operation does:

when the tool is used, a worker holds the handle 2, buckles the first safety hook 4 into the circular ring 3, buckles the second safety hook 6 on a scaffold or a drilling machine main body, then inserts the U-shaped fork 1 in the main body member into a notch of a drill rod lock joint, and starts to assemble and disassemble a drill rod after the drill rod is sleeved in the U-shaped fork 1 in the main body member and manually adjusts the pad fork to a working position.

Obviously, the embodiments in the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that: modifications and equivalents may be made to the embodiments of the invention without departing from the spirit and scope of the invention, which is intended to be covered by the claims.
