Abstract

The invention relates to mining, namely to the means of mechanization of the construction of anchor bolts. The goal is to increase the limits of permissible error of aiming the working bodies on the hole (W) without reducing the operational reliability of the device. For this, it is equipped with a solenoid located on the fixed upper connector (P) 3 of the coupling-conductor. On

The invention relates to mining, in particular to means of anchoring for the construction of anchor bolts in underground workings.

The aim of the invention is to improve the operational reliability of the device while increasing the limits of the permissible error of pointing workers at the borehole.

Figure 1 shows a device for anchoring, the general view; figure 2 - the top and one of the n-izhnyh connectors, cut.

The anchor support erecting device consists of a manipulator 1j on which the expansion mechanism 2 and the upper connector 3 are mounted, made in the form of a conical notch of the coupling-conductor, a pole tip 4 of conical shape fixed on the coupling-conductor's side, from the larger base the conical notch, the solenoid 5, constituting the fixed part of the frame; a drilling machine 6, an injection mechanism for ampoules 7, an ankrusustanovochny mechanism 8 and mechanisms for their supply and thrust on the face, made, for example, for each working member, in the form of screws, pull on the bottom, screws 12-14 of the feed and drive 15- 17. At the same time, on the end ends of the feed screws 12-14, there are installed lower connectors 18-20 of the coupling-conductor, and the diameters of the lower bases of the cones of these connectors are smaller than the inner diameter of the lower base of the truncated notch of the upper slot 3. Connectors 3.18.19 20 completed

When the machine 6 moves to the bottom, the P 18 enters the zone of influence of the magnetic field created by the solenoid. Under the influence of the floor, directed by the concentrated tip 4, P 18 takes a coaxial position with P 3, i.e. P 18 and 3 are combined. This increases the accuracy of pointing the working body to W, the Invention is an additional to the author. No. 1164431. 2 Il.

from ferromagnetic material. The movable and fixed parts of the frame are connected by a pivot jack (not shown).

The anchoring device works in the following way.

Using the manipulator 1, the device is placed on the site of installation of the anchor and spreads into the surface of the mine workings by the spacer mechanism 2. By turning the moving part of the frame, the drilling machine is aligned with the drill hole provided. The drive 15 of the rotation of the screw 9 is turned on. At the same time, the drilling machine 6 advances to the bottom. At the same time, an actuator (not shown) is turned on by a solenoid. When the drilling machine 6 is moving, the lower connector 18 enters the zone of influence of the magnetic field created by the solenoid 5. Under the influence of the magnetic field, directed by the concentrated pole tip 4, the lower axis. 18 with the drill rod of the boring machine 6 is underestimated co-axes. The new position is with the upper connector 3. In this case, gaps are selected that cause the drill string to move relative to the axis of the upper connector 3, and. Connectors are combined.

Then drill the hole. After the end of drilling, the boring machine, turning off the solenoid, returns to its original position. The movable part is rotated, the resetting mechanism is inserted into the ampoules 7, then the anchorage mechanism 8, and the cycle is repeated.

Thus, the present invention allows to ensure reliable positioning of all working elements of the device.
