SU1224406A1 - Method of suspending working platform when sinking vertical mine shafts - Google Patents

Description

The invention relates to mine construction, in particular, to equipment sacking during penetration and fastening of vertical shafts.

The aim of the invention is ... (reduction of energy and cable).

The drawing shows the technological scheme of the suspension of the npoxoA lecKoro shelf, a longitudinal section along the trunk.

The method is as follows.

The rope 1 is completely wound onto the drum, for example, the winch 2. The free end of the rope is successively inserted into the pulleys 3 installed on the scraper 4 and the pulleys 5 mounted on the driving shelf 6 and fixed to the drum, for example, the winch 7. Then 50 -60% of the total length of the rope 1 is wound on the drum of the winch 7, after which the lifting operation of the shelf 6 on the trunk 8 is performed until the rope capacity of the winch 2 is completely exhausted and tension is reached in the upper part of the rope corresponding to its technical characteristics.

The joining of the ends of the rope 1 with the ropes 9 and 10 is carried out alternately. The winches 9 and 10, which are wound on the winch, are connected with the ends of the rope 1 to the pitcher 11, which is placed on the zero frame on this ceriod.

12 (in the drawing, the placement of the ropes 9 and the bow-coupling 11 is shown by a dash-dotted line). When joining, the end of the rope 1 holds the fastening device 13, and the lifting operation of the shelf is performed using a winch 7.

Completing the operation of joining one end of the rope 1 with a test testing the reliability of the joint, which is carried out by creating tension between the winch 2 and the fastening device 13. Thereafter, the fastening device 13 is removed and transferred to the second end of the rope 1, performed in the same way as described.

Depending on the depth of the trunk, the rope capacity of the winches and the technical data of the ropes, the mooring of the ropes can be repeated several times. At the same time, the cross-sectional area of each newly hung rope for identical types of ropes and their materials should be taken larger than the previous one, and the increment of the cross-sectional area of the newly hung rope should be proportional to its own weight 30 and provide an approximate equality of the stress values in the upper sections from ropes.

METHOD OF SUSPENSION OF THE SUSPENDING SHELF WHEN CONSTRUCTING VERTICAL SHAFT SHAFTS, including hanging the shelf on the branches of the ropes, enveloping pulleys located on the pile and the shelf, securing the ends of the kayats on the drums of the driving winches and merging the ends, the ropes with the aim of decreasing energy, which is different, and rope-tight, the ropes are extended alternately from the sides of each branch, while the rope is fixed in the mounting device and disconnected from the drum of the sinking winch, and on the freed drum new rope is wound enlarged diameter d, the value of which is determined by the formula d - J _ ^P 2 ----> (cm) "and of. _about where P is the mass of 1 m of the new rope, calculated in a known manner taking into account the load from the mass of the shelf and the mass of the previous ropes, kg, · ot is the coefficient of filling the cross-sectional area of the rope with metal, depending on the rope construction (for round-strand ropes with an organic core - / = 0.57-0.63), Y is the specific gravity of the rope, depending on the design of the rope (for round-strand ropes with an organic core = 0.0090.01 kg / cm ³ ). °>
