FIELD: mining; transporting.

SUBSTANCE: chain gate for ore chute consists of two rings assembled under discharge opening one above another and oriented in horizontal planes. The rings are tied between them with vertically oriented round-link chains secured on the rings with their ends and arranged along the whole perimeter of rings. The upper ring is stationary fastened under the discharge opening, while the lower ring is kinematically connected with a drive and is designed to turn in horizontal plane. The lower ring is equipped with rollers arranged around the exterior perimeter of the ring at uniform distances; the rollers are designed to rotate around vertical axes and interact with interior surface of a vertically oriented case of cylinder shape; the case envelopes chains with a gap. The case is secured on a stationary foundation. The lower ring from the lower side is made in form of a rim, in the groove of which a steel wire cable is inserted; the cable with its one end is secured on the rim, while with its another end it is tied with a drum, which is kinematically connected to the drive equipped with a breaking facility. In the initial position, when the gate is open, the cable envelopes the rim along the whole length of its circumference, while a slack from the rim strand of the cable envelopes a deflecting unit from below; the deflecting unit can rotate around its axis equipped with sliders; the sliders are designed to be set off in vertical guides and are equipped with a counterweight; in its initial position the counterweight is placed on the foundation. The axis of the drum is assembled so that it exceeds the lower ring at a value bigger, than vertical displacement of the lower ring, when the discharge opening of ore chute is shut; the distance in horizontal plane of the axis of the drum from the axis of the deflecting unit is chosen from the condition of approximate equality of resultant force of tension of tight and slack strands of the cable enveloping the deflecting unit for the lower ring in the initial position and after its displacement upward at closing the discharge opening with curled chains. The case is made with a vertical slot wherein the cable slack from the rim of the lower block can be inserted with a gap; the height of the slot is accepted not less, than the travel of vertical displacement of the lower ring.

EFFECT: invention facilitates simplifying design of chain gate and increasing reliability of operation at discharging lumps via discharge opening of ore chutes of increased sizes.

Ore chute gate. // 2347911

FIELD: mining..

SUBSTANCE: invention refers to auxiliary transport equipment, particularly to gates and is designed mainly for shutting off outlet apertures of ore chutes in mines; it can be also implemented for outlet of lump loads from hoppers. The ore chute gate contains two cylinder bottoms installed under an outlet port secured on two cranks; the said bottoms are designed to rotate in vertical plane into opposite directions against horizontal axes. The axes are located on outer sides of vertical walls of a sleeve and parallel to them. The cylinder bottoms of cranks are arranged overhung with the length of arc corresponding to right angle; free ends of bottoms are directed inside the sleeve. Kinematical connection between cranks is made in form of additional cranks secured on axes. Free ends of cranks are connected with rods of two double-piston-rod actuating cylinders oriented horizontally and assembled with gaps relative to two other walls of the sleeve. In their initial position at an open gate the cranks are oriented horizontally, while the additional cranks form the angle of 45 degrees with the walls of the sleeve; the additional cranks are designed to interact after turn into the direction of the sleeve at the angle of 90 degrees with stops secured on the sleeve. A shield with two sloping surfaces is installed inside the sleeve at the level of axes and parallel to them; the said shield overlaps the end flanges of the cylinder bottoms in plane when the gate is closed and is oriented along the axis of sleeve symmetry. Free ends of the shield are arranged in slots of the side walls of the sleeve and are designed to set off the shield in vertical and horizontal planes. The shield is spring loaded towards brackets of the sleeve by means of a compression spring. At the ends of the shield there are installed unbalance vibrators; their axes are parallel to a lengthwise axis of the shield. Dimensions of the gate are chosen considering the following ratio R=0.5B+a, r<0.355[0.5(B-b)+a-c], where R is radius of the crank, m, r is radius of additional crank, m, B is the width of the outlet port of the sleeve, m, a is the distance between the axis and inside surface of the sleeve wall, m, b is total distance between piston rods and piston rods and end walls of the actuating cylinder for final positions of the piston rods, m, c is the height of the piston rod of the actuating cylinder, m. A replaceable component out of wear and shock resistant material is installed on top of the shield with two sloping surfaces.

EFFECT: increased reliability of operation at unloading oversize lumps through outlet port of ore chute, eliminating possibility of jamming of separate lumps of unloaded bulk between cylinder bottoms and supporting them cranks and avoiding doming.
