(54) DRILL MACHINE MANIPULATOR

one

The invention relates to the mining industry, in particular to manipulators of drilling machines.

A manipulator of a boring machine is known, including a boom with power cylinders and a guide mechanism for advancing the feeder P.

Its disadvantage is low drilling performance, since there is only one feeder with a drilling machine on the boom.

The closest in technical essence and the achieved result to the proposed is a manipulator of boring machines, inclusive boom with forces No.4 and cylinders, a central beam with a yoke, pivotally attached levers on which the sensors of boring machines are fixed, the mechanism of the central beam pulling on the face 27.

A disadvantage of the known manipulator is that it is impossible for them to drill a bunch of boreholes p.

in different planes, and it is also impossible to provide the same thrust of all drilling machines.

The purpose of the invention is to expand the field of mechanic pumping by simultaneously drilling a blast-beam and ensuring uniform spreading of the drivers.

The goal is achieved by the fact that the central beam has an outward slider pivotally connected with the 1st levers to the pads, at the ends of which there are stops with hydraulic arcs, with the cavities of the same drive of the same name communicating with each other.

In addition, feeders with levers are located in planes intersecting along the center beam.

Claims (2)

FIG. 1 shows the proposed manipulator, side view; in fig. 2 is the same front view; or FIG. 3 - hydraulic drive of the stops. The proposed manipulator is as follows. The rotator 1 is pivotally connected to the boom 2 with its lifting drive and the holder A, in which the central beam 5 is installed, carrying the actuator 6 of the sliding slider 7, the holder 8 with the driver 9, the levers 10 of the hinge parallelograms and the feeders 11 with drilling machines 12. The holder 8 are pivotally connected by levers 13 with feeders 11. At the end of each feeder, extendable stops I4 are fastened with their own hydraulic drives 15. A drive 16 is provided for moving the beam 5 along holder 4, and a drive 17 is provided for inclining holder 4 drives communicated among themselves. The simultaneous operation of all the stops is achieved as follows. Since the like cavities of the actuators 18 or 19 communicate between themselves, respectively, with the supply sleeves 20 and 21, when the liquid is supplied to the strips 18, all the stops 14 are simultaneously pulled out and pressed to the face with the same force, the uniform delivery of all feeders is achieved . At the end of drilling, when the fluid in the cavity 19 is supplied through the sleeves 2, the lugs 14 are pulled in. The work of the manipulator is as follows. The manipulator is mounted on drilling rigs or drilling machines. Using the rotator 1, the boom 2 is set by the actuator 3 to the desired position for drilling a set of holes. By means of the actuator 17, the required inclination of the holder 4 is carried out. With the aid of the actuator 9, the casing 8 is moved along, the caps 5. Since the levers 10 and 13 are hinged to the feeders 1I and form the hinge parallelograms with the latter, move the feeders 11 away from the beam 5 to the desired value. . If it is necessary to tilt the feeders 11 by means of the drive 6, it is possible to extend or retract along the zune 7 together with the front levers 10. After setting the feeders 11 to the required position, the beam 5 is pulled down by the feeders 1 1 to the bottom by means of the drive 16. At 94 In this way, the beam 5 moves along the holder 4. In order to provide an emphasis for each feeder in the face, the drives 15 of the stops 14 are simultaneously turned on. This completes the setting for drilling. The drilling of a set of holes is carried out simultaneously by four drilling machines I2. After the drilling of one set of holes is completed, the drilling machines 12 return to the rear position, the stops 14 are drawn in by the drives 15, the beam 5 with the feeders 11 is moved away from the bottom by the drive 16. Then, with actuators 3, 17 and rotator 1, boom 2 is installed in a new position and the drilling cycle is repeated. The advantages of the proposed manipulator are increased productivity due to simultaneous drilling of a hole beam from one position, reduction of time spent on auxiliary operations when setting up drilling feeders, and the possibility of changing the distance between feeders and their inclination. Claim 1. Manipulor of boring machines, including boom with power cylinders, center beam with a yoke, pivotally attached levers on which feeders of boring machines are attached, mechanism for pushing the center beam to the bottom, characterized in that in order to expand the scope of use of the manipulator by simultaneously drilling the blast hole and ensuring uniform spreading of the feeders, the central beam has a retractable slider pivotally connected by levers to the feeders, at the ends of which there are stops with hydraulic actuators, with the same name cavity of these actuators communicated with each other. 2. A manipulator as claimed in claim 1, characterized in that the feeders with levers are located in planes intersecting the axis along the axis of the central beam.
