Abstract

SUMMARY OF THE INVENTION: the hoist is made of two identical running carriages with blocks and eyes, between which a hydraulic cylinder is mounted, the blocks being paired on one axis, and the hoisting rope made of two parts, each of which is attached to one of the carriages at one end, and, the opposite block of the carriage, through the block of its carriage is connected to the suspension element. 4 ill.

Description

The invention relates to mining and is intended for installation, dismantling and handling operations.

The aim of the invention is to simplify the design and maximize the unification of the units of which they are composed.

In FIG. 1 depicts a monorail track in a drift with a race in dissection, a general view; in FIG. 2 - monorail track in the section of the drift; in FIG. 3 - lifting device; in FIG. 4 is a section AA in FIG. 3.

The monorail track according to the invention is intended mainly for the installation of panel ceilings and loading and unloading operations on the panel section. It consists of a monorail (I-beam, rail) 1, attached to the frames of the roof support of the drift, the mounting chamber (cut) by means of a rope 2, passed over the upper supports of the support and through the grippers 3 mounted on the upper shelf of the I-beam 1, and a lifting device 4, suspended on suspension and movement elements to the bottom of the monorail. The lifting device 4 consists of two running carriages 5 with eyes 6, between which a hydraulic jack 7 is mounted, fixed in the eyes 6 through the fingers 8.

Each running carriage 5 is made of two pairs of rollers (rollers) 9 mounted on axles x 10, rigidly fixed in the side walls 11 of the carriage body. In the lower part of the carriage, on one finger 12, two blocks 13 are installed for the hoisting rope 14. The hoisting rope consists of two equal segments, each of which with one end 15 (16) is fixed on one of the carriages in the lower front part under the hydraulic cylinder 7, and, the bend the block of the opposite carriage, through the block of its carriage, is connected to the - hook suspended 17 (18). Thus, the lifting device has two lifts.

cable-rope systems with their hook pendants synchronously driven from one hydraulic cylinder.

Works lifting device as follows.

In the initial position, the hook hangers 17 and 18 are in their highest position, under the carriage, the rod of the hydraulic cylinder 7 is fully extended. In order to lift the load located in the realm of the monorail, the lifting device 4 rolls along the monorail 1 to it, the hydraulic cylinder 7 is turned on to retract the rod, the carriage 5 is locked to its extreme close position; hook pendants 17 and 18 are lowered downward into the double stroke of the spreader rod. The cargo is slid onto one hook "both hook suspensions 17 and 18. The towing cylinder is engaged to extend the rods, carriages 5 together with blocks 13 are consumed, the load rises to the required height and is transported to the installation site (unloader). During unloading, the hydraulic cylinder is engaged to retract the needle. carriages 5 are coming off the vehicle and the load on the hook suspensions is lowered to the workway or laid in the azk © design. For example, in a panel board for working out cool shes. In this case, it is necessary to note the advantage of the dachshund

load-lifting device 4, as a general feature of its execution: carriages 5 are installed at the ends of the hydraulic cylinder. This allows the installation of a south-facing sandwich at the very end of the roof,

because the carriage 5 can be installed at the very boundary of the cut.

When delivering long material, such as a wooden knurl or rolled metal beams for the frame of the shield section, the load rises on two ropes and is thus transported into the cut, where it is lowered onto. the soil is attached to one hook suspension, it rises, rotates 90 ° and is laid across the strike of the formation.

Where it is not possible to ensure the arrival of the lifting means and the cut-off is not too long, two lifting means are mounted from the ventilation drift (due to the large difference in the heights of the workings); one in the drift, the other in the cut.
