专利摘要:
Apparatus for controlling the position of a mineral mining machine, such as a plough, movable along a main guide at one side of a scraper-chain conveyor employs cantilevered beams extending between the conveyor and a series of roof supports. Each beam is preferably resiliently flexible and is connected, for example via a bracket at an opposite side of the conveyor, to the main guide. A device, such as a hydraulic piston and cylinder unit, is used to adjust the inclination between the beam and the guide in generally known manner. The end portion of the beam remote from the conveyor extends alongside a side mounting surface of the floor structure of an associated one of the supports which mounting surface faces the next adjacent support. A further guide means, which may take the form of a tube containing a ball or a similar guide member or a guideway along which a guide member is displaceable, is detachably secured to the mounting surface of the support. The guide member of the further guide means is connected to the end of the beam so as to support the latter while allowing some free pivotal displacement in all directions as well as displacement axially and parallel to the support.

(54) DEVICE FOR CONTROLLING A SLIDING STRING INSTRUMENT IN A VERTICAL PLANE
one
The invention relates to mining. case, in particular, to devices for controlling sliding plows. vertical plane.
A device for adjusting excavation machines for formation hypsometry is known, including a control jack mounted on the tailgate, a pull located under the conveyor, and a double-arm lever hinged to the tailplate of the conveyor 1. The disadvantage of this device is to increase the height of the mineral loading by conveyor and design complexity.
It is also known a device for controlling a sliding plow unit, comprising a rod, hinged at one end with a plow conveyor and a hydraulic ram, and a device for fastening the other end of the rod 2. The device’s disadvantage is that the bases of the lining.
The aim of the invention is to improve the accuracy of regulation. This goal is achieved in that the device is equipped with a spherical element fixed at the other end of the rod and a guide tube in which the end of the rod with the spherical element is placed with the possibility of limited horizontal movement.
The drawing shows the proposed device, consisting of a rod 1 and a guide 2 in the form of a segment of a cylindrical tube, in one open end of which a rod enters. The rod 1 has a spherical element 3 at the other end of the developed space, the outer diameter of which has the same size as the inner diameter of the guide tube 2. Since the diameter of the rod is much smaller than the inner diameter of the guide tube, the rod has inside the guide tube 2 to adjacent to its inner wall, sufficient freedom of movement in all directions.
To the base of the mechanized support 4 from the external side 5 it is attached by means of the flanges 6 of the guide tube and bolts 7 of the guide 2. The attachment of the guide 2 to the support sections can be made so that there is the possibility of lateral adjustment of the guide
