Description

Safety device for preventing drilling machine drill rod from sliding down to hurt people

Technical Field

The utility model relates to a prevent that rig drilling rod from gliding hurting people's safety device belongs to drilling rod auxiliary fixture technical field.

Background

At present, with the increase of the coal mining scale, the problem of gas treatment is obvious, the difficulty of gas treatment is continuously increased, the requirement on the gas treatment level of a coal mine is continuously improved, the requirement on the working efficiency of a drilling machine is continuously increased, and a high-power drilling machine is continuously introduced and adopted in a coal mine to improve the construction efficiency of drainage drilling holes;

the high-power hydraulic drilling machine is mostly adopted in a mine as construction equipment for drawing and releasing drill holes, the hydraulic drilling machine is high in efficiency, the single-day footage is large, but some safety problems exist, the problems that the drilling machine is long in service cycle, not in place to overhaul, high in failure rate and the like generally exist, especially, the problems of liquid leakage and pressure release frequently occur in a hydraulic power system, the drilling machine is not in place to maintain, and potential safety hazards can be caused;

in the construction process of pumping and releasing a drill hole, in order to ensure that a control range is in place, a large-angle drill hole (more than 45 degrees) must be constructed, the drilling machine is difficult to avoid the occurrence of the fault shutdown maintenance and the like in the midway of drilling construction, in the maintenance process, due to the fact that the construction drill hole is deep, repeated up and down drilling rods seriously affect the efficiency of the drilling machine, but due to the existence of the conditions of leakage and pressure relief of the drilling machine and the like, a hydraulic system cannot ensure the safety and the reliability of the drilling machine clamp for long time under pressure, the hydraulic failure of the clamp continuously occurs in the practical process, the safety accident that people are injured by the drilling rods downwards brings severe challenges to the safety production of mines.

Aiming at the situation that the drilling rod with the leakage pressure relief and large-angle drilling of the hydraulic system of the drilling machine has the gliding risk due to the dead weight, the safety facility of the drilling machine is improved, the safety device is added, a second safety barrier is provided for fault maintenance in the construction process of the drilling machine, the risk of safety accidents is avoided, and the drilling machine is worthy of wide popularization and use.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the utility model provides a prevent that drilling machine drilling rod from gliding injury people's safety device to solve the problem that exists among the prior art.

The utility model discloses the technical scheme who takes does: the utility model provides a prevent that rig drilling rod from gliding hurts people's safety device, includes U type card, splint and lock nut, and two free ends pass splint and adopt lock nut to lock behind the U type card income by drilling machine holder slips of drilling one side.

Preferably, the U-shaped clamp, the clamping plate and the locking nut are at least two groups of clamping slips which are tightly held on the drilling machine holder.

Preferably, the clamping plate is configured to conform to an arc-shaped structure of a slip surface of a drill holder.

Preferably, an elastic protection layer is arranged on one side of the clamping plate contacting with the slip of the drilling machine holder.

The utility model has the advantages that: compared with the prior art, the utility model discloses install in rig holder the place ahead, near the rig holder, through lock nut, the common locking effect of U type card and splint, make the slips press from both sides tight drilling rod, utilize the holder to support safety device's U type card or splint simultaneously, can prevent that the drilling rod from sliding when drilling machine breakdown shutdown maintenance is overhauld in drilling construction midway unavoidably appearing, avoid causing the incident, provide the second safety barrier for troubleshooting in the rig work progress, and need not frequently go up and down the drilling rod among the maintenance process, a large amount of time has been saved, the construction work efficiency of rig has been improved, the time of working has won for gas improvement, reduce the incident simultaneously, guarantee mine safety in production.

Detailed Description

The invention will be further described with reference to specific embodiments.

Example 1: as shown in fig. 1-2, a prevent that rig drilling rod from gliding injury people's safety device, including U type card 1, splint 2 and lock nut 3, two free ends pass splint 2 and adopt lock nut 3 to lock behind the rig holder slips 4 that leans on drilling one side are blocked to U type card 1 card, the locking safety mechanism locking that splint 2 and lock nut 3 constitute is adopted outward to rig holder slips 4 that is located 5 the place ahead of rig holder, thereby realize the fastening of drilling rod, with the drilling rod, rig holder slips and safety device connect into whole, support under the limiting displacement who leans on rig holder 5 front end at safety device, avoid the drilling rod to glide.

Preferably, the U-shaped clamp 1, the clamping plate 2 and the locking nut 3 are at least two groups of clamping slips 4 which are tightly held on the drilling machine holder, so that the fastening reliability and the limiting reliability of the safety device can be improved.

Preferably, above-mentioned splint 2 sets up to the arc structure on laminating rig holder slips surface, and the increase area contact slips of being convenient for plays fastening effect better, and reduces concentrated stress, avoids damaging the slips.

Preferably, an elastic protection layer is arranged on one side of the clamping plate 2 contacting with the slip 4 of the clamp holder of the drilling machine, so that the safety protection effect is achieved.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
