Description

one

The invention relates to the field of the mining industry, namely to devices for laying augers on a drilling platform of an auger drilling machine.

A device for laying augers on a drilling platform of an auger drilling machine is known, including its carriage and a mechanism for lifting and laying of augers 1.

The disadvantages of this device are the necessity of using manual operations for the attachment and detachment of augers from the lifting hook, which does not provide safety of work and high productivity; the possibility of rocking the screws on the hoisting rope, which leads to inaccurate laying on the drilling platform in the longitudinal and transverse directions; the difficulty of laying augers on the drilling platform in auger drilling machines that drilled inclined formations.

The closest of the known technical solutions is a device for laying augers on a drilling platform of an auger-drilling machine, including its carriage and a traverse, on which the clamps are fixed to hold the augers 2.

However, this device has a large overall size and a large installed mosh, a drive unit for moving cantilever augers through sprockets. In addition, to ensure the folding of a large number of spare augers, the use of two devices located on the sides of the drilling platform of the machine is necessary.

The purpose of the invention is to simplify the construction.

This is achieved by the fact that the carriage is connected to the crosshead by means of a vertical connection and a hinged four-tiered bar, in the lower part of which there is a reinforced turning stop and a hook with a copier, and on the traveling beams of the carriage there are directional and spring-loaded stops.

FIG. 1 shows a device for stacking augers, batt, i vnd; in fig. 2 - the same, with the inclined position of the screws; in fig. 3 - view along arrow A on the fng. one; on. FIG. 4 — carriage coupled to the crosshead by means of a hinge four-piece; in fig. 5 - traverse and its coupling element; in fig. 6 is a view along arrow B in FIG. five; in fig. 7 - traverse and its communication element; in fig. 8 - view along arrow B on

FIG. 7

The screw laying device comprises a carriage 1, spring-loaded stops 2 and 3, a hinged four-hatch 4, a vertical link 5, a turn stop

6, the yoke 7 with the grippers 8 and 9 fixed to it for screw sections of the drill rod and the locking pin 10.

On the axis connecting the vertical link with the hinged four-bar, a latch 11 is installed with a cam 12. The deflecting in one direction the guides 13 and 14 are rotatably mounted on the axes x 15 and 16.

Each guide has the ability to turn in one direction, its turn in the other direction is limited by brackets 17 and 18.

The connection by means of a vertical connection 5 of the hinged four-bar with cross-member 7 allows the latter to adopt a slope corresponding to the installation angle of the drilling platform of the auger-drilling machine. The angle of inclination of the crosshead is limited by means of vertical rotation stops 5 mounted on the vertical connection 5. The hinge four-link 4, which serves to avoid swinging sections of the drill rod, is compressed (folded) while lifting, and lowered is expanding.

As shown in FIG. 5-8, on which the yoke 7 is depicted in the upper position, the vertical link 5 does not interact with the camcorder 12. The latter, together with the latch 11, is only mounted on an axis connecting the vertical link with the hinge four-bearing member. Copier 12, when moving the carriage along the track beams of the upper frame of the machine, interacts with guides 13 or 14.

When moving the carriage with sections of the drill rod in the automatic grippers 8 and 9 or without them, the yoke 7 is always in the upper position (the hinged four-dialer is compressed). In the case of movement of the carriage from the containers for gear sections to the drilling platform, the copier 12 finds a guide 13 or 14 that is deflected to one side and, lifting it, lifts the latch 11 out of the joint with the fixing finger 10 fixed on the cross bar 7. The 13 or 14 is then clamped to the limiting bracket 17 or 18.

The latch 7 released from the latch 11 (the latter is connected to the vertical link 5 with the center of gravity shifted towards the tilting of the drilling platform) is at an angle equal to the angle of tilt of the drilling platform. The angle of inclination of the yoke 7 is controlled by a limiter 6 fixed to the vertical link 5.

When the carriage reaches the middle of the drilling platform, the carriage stops and the traverse at

This one of its ends deflects the spring-loaded stop 2 or 3. The latter are installed above the longitudinal axis of the drilling platform.

In the inclined position of the yoke 7 (with sections of the drill rod with or without automatic grippers) is lowered onto the drilling platform.

When lifting above the drilling platform

in the upper position of the yoke 7, one of the spring-loaded stops 2 or 3 (depending on the position of the yoke of the yoke) is horizontally aligned, and the latch 11 in this sl i under the action of its own weight and weight

The copier 12 is lowered and comes into contact with the locking catch 10, closing the traverse in a horizontal position.

After lifting the yoke, the carriage moves to one of the sides to the containers.

for spare augers. In this case, the spring-loaded stops 2 and 3 are deflected in the direction of movement of the carriage, and then, when passing under them, the traverse 7, occupy a vertical position. When moving

the carriage to one of the containers for the spare sections of the drilling rig, the copier 12 passes under the guide 13 or 14, the latch 11 is no longer disengaged from the finger 10, the copier 12 raises (shown by the arrow) the guide 13 or 14, which rotates the axles x 15 or 16.

If it is necessary to lay the sections of the drilling rod on a horizontally located drilling platform, only fixing the crosspiece 7 is carried out using height-adjustable restraints 6 in a horizontal position.
