SU50424A1 - Self-Tipping Trolley For Mine Way - Google Patents

Description

Trolleys transported by a rope and automatically tilting by means of a traveling stop installed at the place of unloading are already known.

The proposed trolley differs from the previously known ones in that its body is provided with side sectors with which the trolley rolls over specially laid tires in the way and thus is brought to the overturned position. The aim of the proposal is to mechanize the laborious process of removing ash from boiler houses, which takes place in difficult and harmful conditions.

In addition, the proposed trolley can also be used on any waste pits, almost necessarily available at every mining enterprise.

The drawing shows an exemplary form of execution, and fng. 1 is a side view of a sloping road with a trolley transported by a rope; FIG. 2 is a cross-section of AB of FIG. 1 and FIG. 3- device plan.

The car body is made of thin sheet iron. Side 2 and rear / body walls are made plumb. Front wall J tilted forward. The bottom of the trolley is parallel to the way of the heaps and reinforced with bolts on the chassis, which is a frame 4 of channel iron with wheels 5 mounted on it.

The walls and the bottom of the body are connected by a frame made of angular iron. On both side walls there are reinforced sectors 6 formed by spokes from light channel iron and angular iron bent in an arc of a circle. Fingers 7 are fastened in the center of this circle. They are put on glands 8, the other ends of which are tightened with nuts in a cross-bar 9 from light channels. Toward the middle of this cross-bar is attached a traction cable 10, thrown over the pulley 16 75 slaughtering

The hemlock frame consists of two channel or I-beams 11, connected by rail ties 12 with channel iron 12. Rails 13 are fixed on the sleepers. Not far from the end of the frame, beam beams 14 are riveted to the beams, on the upper shelves of which are welded

strip iron tires 17, terminated by limiters, prevent the trolley from being pulled further than necessary for its complete emptying and, therefore, the cable clips fall into the pulley.

The trolley receives the load from the receiver, from which the heap of a heap begins. After filling the trolley, the winch motor is turned on and the trolley, pulled by the rope Yu, thrown over the pulley 76 I on the frame head, rolls on the wheels 5 but on the track 13 laid on the waste dump.

The trolley continues its normal movement until the stops on the side sectors 6 of the body touch the edge of the tire 77. At this moment the trolley stops just enough that the tension of the rope increases due to the winding on the winch drum , it turned out to be sufficient to rotate the laden trolley around an axis passing through the upper edges of the end of the tires 77. This period of motion is; The races continue until i, until the axis connecting the fingers 7 is perpendicular to the elevation — j, the axis that passes through the I upper faces of the tire end 77. Starting from this moment, the trolley rolls but these tires on their sectors 6, turning about the axis passing through the fingers 7. This period of movement of the trolley continues until its complete emptying, when it is upturned by its side sectors to the stops, which 17i canned

It should be noted that already in | the first period of the trolley movement during the overturning it knocks its 5 track track with its wheels. The rail track of the heap in this place ends, since its further laying along the frame would prevent the trolley from completely overturning.

due to the fact that the front wall of the body would rest on the rails.

Since the center of gravity moves along the emptying of the trolley closer to the ramps, a torque is generated around the fingers 7, to which the straps 8 are attached, causing the trolley to go back when the tension of the rope is relieved; it rolls down-at the beginning on its sectors, then turns near the end of tires 7 and, leaving them, sits its wheels on the track and rolls down like a regular trolley.

The side of the heap is laid in such a way that the unloading place is at a distance of 1 - 5 lg ahead of the top of the heap. To prevent the frame from tipping over during the entry of the trolley onto its hanging part, the end of the frame lying on the dump is loaded with a correspondingly calculated counterweight consisting, for example, of several rails laid between rail tracks.

As soon as the rock that has been poured out from the car begins to prop up under the frame, it is necessary to push the frame forward along the wreckage each time for a distance of 1-1.5 m. This is pulled out by a screw or hydraulic jack (separate or arranged in the frame) that is installed between railroad frame and rail tracks

The subject matter of the invention.

A self-tipping trolley for a mine road, the tilting of which is produced by means of a support stop installed in the path of movement of the trolley, characterized in that the trolley is provided with lateral sectors rolling on the tires, which terminate at the rollover site, and ending with the stops.
