Description

The well-known;) c1z, .this tpnyhs; l lizlliUJl - ;; piH () go to each other, whose Section1G1 consists of racks, not o) Ec:; e- and; 5 give an unwritten change in the height of the section.

In the proposed fastening, this disadvantage is eliminated by the fact that the stacks supporting the upper part of the section are connected to each other by the roof of the ball N1 balls.

FIG. 1 shows a mechanized roll, side view; on shit. 2 - view of details in the plan.

Each securing section consists of three telescopic flexible legs J, 2 vi 3, arranged in a triangle, the base of which is parallel to the chest of the bottom. The first rack / installed at the bottom, and the two rear pillars (organ) 2, 3 - at the dam. All three racks in each, the panel mounting sections are interconnected at the top by means of ball joints 4 and form a triangular cage of each section.

Organ pillars 2 and 3 are joined together at the soil by a flexible pad 5, and at the top by a steel plate 6. Last, as the most loaded with the pressured roof, it is reinforced with corners 7, welded to beam 8, which is the top frame of each section, and the rod connecting through a spherical hinge 4 a rack with racks 2 and ... The rear organ racks are identical in design and consist of two pipes of different diameters telescopically inserted into one another. With their pipe ends, they enter support shoes 9. A ball 4 is welded to the bottom of the upper support bar 9, inserted into the ball pin 10.

After raising the organ section of the panel mount against the roof and separating the pipes of the uprights L 2 and 3 to the required height, the pipes are fixed with brake collars // by means of wedge-shaped pads 12, adjusted with screws 13. For fixing the length of the uprights, there are stop collars 14, tightened with screws / 5 .

M 91934-2 The bottom rack 1 differs from the organ 2 and 3 racks only in that the bracket 16 is welded to the upper shoe 5 and to the end of the shoe 17. 17. To support the roof and avoid beating "and racks 2, 3 to the organ plate 6 safety beam 1 CYTOC 18 is welded to beam 8 at the same time as tefediaziachenny to divert the roof; it has roofs from racks 2, 3. In each section of the shoe there are shoes 9 racks 1, 2 and 3 connected together between each beam with beam 19, fastened with one end to the tower 9 , and the second to nlanka 5. Onuskahanie all three racks /, 2 and 5, and produces nose1) food Own dead weight of the upper section of the mount.

The raising of each section of the shield to the roof of the drainage, there is a fragile atom 20 mounted on the plate 21. A winch 22 serves for stirring the section in the shear mount. It is mounted on the sides of the bottom-hole conveyor 23.
