(54) MINE LOADING DEVICE

one

The invention relates to ancillary equipment for mechanized haulage of goods and can be used for loading bulk materials of various vehicles, such as mine trolleys.

Known loading device for mine cars, containing, its loading hopper with two oppositely directed trays equipped with flaps 1.

However, the design of the device is complicated both in manufacture and operation. JQ In order to implement the initial loading period, it is necessary that, as a means of delivering the cargo, so that the loading dual chute is moved together with the car. The operation of the boot device is controlled by a complex electrical automatic control system.

The purpose of the invention is to increase efficiency and safety at work.

This goal is achieved by the fact that in the device the bills are arranged vertically with the possibility of moving in a vertical plane and provided with rollers, and on the VAGONETO

The side walls of the trolleys are fixed with guides for the rollers indicated.

In addition, the guides should preferably be trough-shaped, the depth of the depression should be equal to the height of the protruding part of the flap above the tray base, the horizontal sections along the edges should have a length equal to the width of the outlet of the tray, and the side walls of the guides should be located angle not exceeding the friction angle of the roller on the inclined section of the head. Figure 1 shows the loading device for the trolleys at the moment when the roller comes into contact with the guides; in fig. 2 - the same, the moment when the two rollers are on the straight part of the middle part of the guides; in fig. 3 - the same moment, when one roller pushes out of contact with the guides, and the second one comes into contact with the straight part of the extreme part of the guides; in fig. 4 shows section A-A in FIG. one.

Loading device for utility trolleys contains loading hopper 1 with

trays 2 and 3. Tray 2 is equipped with a vertical flap 4, and tray 3 is equipped with a vertical flap 5. Roller 6 is fixed on flap 4, roller 6 is fixed on flap 5, and trough-shaped guides 9 are fixed to flap 5. 5 are associated with elastic supports 10.

The boot device operates as follows.

The empty trolley 8, when approaching the loading point by means of guides 9, comes into contact with roller 7. Roller 7, carried away by guides 9, rotates around its axis, and remains in place until the trolley is displaced by an amount equal to the length of the extreme horizontal section 9.

Then, coming into contact with the inclined section of the guides 9, the roller 7 moves downward under the action of the forces from the guides and goes to the middle horizontal section of the guides 9, carries the valve 5 rigidly attached to it and sets it to the lowest position where the protruding part of the flap 5 is installed at the level of the base of the tray 3. Thereafter, the bulk material from the hopper 1 located above the loading device, through the tray 3 begins to flow into the body of the trolley 8.

As the loaded trolley 8 moves under the loading device, the roller 7, being on the horizontal middle section of the guides 9, keeps the flap 5 in the lowered position, ensuring that the trolley body loading continues through the tray 3. In addition, as the train progresses 9 comes into contact with the roller 6 of the shutter 4 of the tray 2 and, having traveled a path equal to the total length of the extreme horizontal and inclined sections of the guides 9, reaches a position at which the rolls b and 7 of both shutters 4 and 5 mounted on a horizontal portion of the middle part of the guides 9.

In this case, the loading of the trolleys is carried out simultaneously through both trays, for the flaps completely open their outlet openings.

Further, in the process of moving the trolley, the roller 7 of the flap 5 of the tray 3 comes into contact with the opposite inclined section of the guides 9 and, rotating around its axis, rises upward, extending the flap 5, resulting in blocking the flow of bulk material through the tray 3. Then the roller 7 extends to the outermost portion of the guides and locks the flap 5 in the extended position. After the loaded trolley is moved by an amount equal to the length of one extreme straight section of the guides 9, the roller 7 of the shutter 5 comes out of contact with the guides and is held in a fixed position by the flexible support 10, which can be used as a spring, until the empty trolley approaches. Roller 7 then comes into contact with the empty trolley and

the process of interaction of elements of the boot device is repeated as described above. Following the roller 7, it leaves the contact with the guides of the loaded trolley roller 6 and, following the roller 7,

comes into contact with an empty trolley and the process continues according to the above scheme.

Execution of the charging device of mine wagons in the form of multidirectional trays, overlapped with flaps,

Equipped with rigidly mounted rollers that come into contact with guides fixed rigidly on the side walls of the trolleys will allow a 50% increase in the productivity of locomotive haulage in mines by reducing the downtime of trains at loading points and increasing the completeness of loading the trolleys. In addition, the degree of contamination of haulage workings at loading points will decrease, which in turn will reduce the delay of trains at loading points due to debris and possible train derailments from rails, significantly improve the working conditions of workers loaded with mine trolleys, and improve safety by excluding the presence of a person performing the operation of opening and closing the dampers.
