Abstract

The invention relates to mining equipment and improves the blasting capacity and maneuverability of the actuator in breaking down hard rocks. The actuator is designed as cutting disks 1 mounted on shaft 2. One end of shaft 2 is mounted on boom 4 and the other is connected with it by means of intermediate element 5. Hydraulic hammer 6 is located along boom body 4 with longitudinal displacement through hydrojacks 7 4 is integrated into the guide bushing 8, on which the actuator 9 is rotated around its longitudinal axis. The plunging of the diamond discs 1 is performed by feeding the boom 4 to the bottom. Further cutting of the slots is performed by feeding the boom 4 from the bottom up and from the top down. The cleavage of the interstitial pillars is carried out by hydraulic hammers 6. 1 c.p. f-ly. 2 Il. 2 e (L with sd oo oo J2 ig.1

Description

The invention relates to a mining pass-for new embedding the position of the production equipment intended to destroy part of the gap between the pillars.

for mechanical destruction of mountainous by-14 hydraulic hammers 6. Thus,

born sh, ate on one half of the bottom

The purpose of the invention is to increase the production and partially destroy the breaking and maneuverability of the gap between the pillars of the pillars 14 here. yut.

the rock massif, top view; 10 After cutting the slots with the desired bar in FIG. 2 - the same, lateral view of the entire slaughter at the bottom of the slaughterhouse. The executive body of the excavation of the remaining intergap pillars 14

the combine consists of cutting discs 1, and the contouring of production by manipulating on shaft 2, one end of the boom with working hydro, which enters the reducer 3, is made-. drummers 6.

polpatelnogo body in the destruction of strong rocks.

FIG. 1 shows the executive body of a tunneling machine when it is destroyed in the front of the boom body 4, and the other is mounted in a bracket 5 rigidly connected to the boom body 4. Hydraulic hammers 6 according to the formula move along the boom body 4 along the guides

. The executive body of the roadheader, including the boom, is mounted by means of a hydrojack 7. The boom case 20 on its front part is 4 integrated into the guide sleeve 8 of the intermediate element

cutting discs, which is located perpendicular to the axis of the boom, and installed on the front of the latter, a hydraulic hammer 9 is installed with the drive for turning the boom around its longitudinal axis. The guide sleeve 8 is included in the guide frame 10 of the executive body

-, - NIKI, characterized in that, in order to go, relative to it, the cutting capacity and the boom are moved together with hydraulic jacks 11. The negligence of the actuator during the disengagement is carried out by the electric motor destroying strong rocks, and the spans are transmitted to the gearbox 3 through the shaft 13. the exact element is designed as a rigidly

The Executive body of the passage attached to the boom arm, and the combination works as follows. water shaft with one cutting discs

the end is mounted on the brace and the other on the boom, on which the hydraulic hammers are mounted with the possibility of longitudinal movement to the opposite side of the drive shaft relative to the axis

The destruction of the excavation begins with the cutting of vertical cracks in the middle part of the bottom. The cutting of the cutting discs 1 is carried out by feeding the entire boom to the bottom by hydraulic jacks 11, for example, in the middle of the bottom at its lower part, and the distance from the boom, while the front part of the boom slitting the slit of the slit is made under the upper arm. . After the cutting, relative to the boom axis,

nor this group of slits cutting disks 1

2. The actuator according to claim 1, characterized in that the axes of the hydraulic shock output from contact with the bottom by means of hydraulic jacks 11 and horizontal movement of the boom body 4 40kov are located in a plane parallel to the rearranged to a new row. cutting discs, and from top to bottom of the boom in the original multiple of their installation.

Claims (2)

Claim 1. The executive body of the roadheader, including the boom, is mounted- 20 drive shaft with cutting discs located on its front part through an intermediate element, which is located perpendicular to the axis of the boom, and mounted on the front part of the last hammer 25, characterized in that, in order to increase the performance of breaking and maneuverability of the executive body during the destruction of strong rocks, the intermediate element is made in the form of a bracket rigidly attached to the boom, and at 3Q a water shaft with cutting discs is mounted at one end on the bracket and the other at the boom, on which the hammers are mounted with the possibility of longitudinal movement and on the opposite side from the drive shaft relative to the axis 35 of the boom, while the front of the boom is connected to the rear with the possibility of rotation relative to the axis of the boom. 2. The executive body for π. 1, characterized in that the axis of hydraulic hammer 40 forks are located in a plane parallel to the plane of the cutting discs, and at a distance multiple of the step of their installation.
