Abstract

SUMMARY OF THE INVENTION: An overlap is located between the coal and rock-dropping device and the composition of the trolleys; it comprises a chain circuit with overlapping shelves with carriers included in it. The carrier has been successively in contact with the trolleys, due to which the composition of the trolleys simultaneously rotates the chain circuit with the shelves. 4 C.p. fs, 3 ill.

Description

The invention relates to the field of coal industry and is intended to equip coal transfer points in trolleys.

The aim of the invention is to ensure reliable operation of the overlap and to reduce its vertical dimensions.

The overlap device is shown in the drawings, where in FIG. 1 is a plan view, in FIG. 2 is a longitudinal section, FIG. 3 - cross section.

The overlap is placed between the coal-dropping device and the composition of the trolleys and includes a frame 1 with two parallel guides 2, an overlapping device 3, consisting of consecutively and evenly spaced regiments 8 with carriers 4 made up of pipes 9. parallel chain circuits 6 , four sprockets 7, connected in pairs by shafts, deflection device 5 and tension device 10.

The operation of the overlap is as follows.

When the composition of the trolleys moves (the direction of movement is indicated by the arrow), the working carrier 4 (i.e. the carrier in contact with the trolley) located between the cars is moved by the car and leads its working shelf 8 (and with it the entire chain circuit) along the lower guides , which covers the space between the cars along its entire path, and non-working shelves with folded carriers are forcibly moved in the opposite direction along the upper rails. During the approach of the working carrier to the diverting device, the next carrier drove under its own weight into the subsequent intercar space.

When the working carrier passed through the deflecting device, the profile face of the latter turns the carrier into a horizontal idle position, bending through the sprocket, the working shelf goes to the upper guide and discards the corner cone into the trolley, and the next carrier becomes working and its subsequent shelves overlap the subsequent intercar the space is already at the beginning of its path to the passage under the flow of coal.

laying, on its way the short-term is filled with coal, but when passing under the transverse sheet of the frame, dumps it into the trolley. A spring tensioning device constantly pulls the chain, despite the change in the length of the chain contours associated with the non-synchronous rotation of the pair of sprockets.

The proposed shutoff reliably operates in an automatic mode, allows for in-line high-performance coal reloading in trolleys without loss of coal in both underground and quarry conditions.

Claims (5)

SUMMARY OF THE INVENTION 1. Overlap of the inter-car space, including a frame with guards, a mechanism for dropping them, overlapping the carrier mechanism, characterized in that, in order to increase reliability in operation, the guides are closed and provided with parallel endless chain 0 5 0 contours with asterisks, while the overlapping mechanism is made of regiments attached to said contours, pivotally connected to one end of the carrier with the possibility of their rotation in the vertical transverse plane. 2. The overlap according to claim 1, with the exception of the fact that, in order to reduce the overall dimensions, the shelves are made flexible of pipe sections articulated between each other. 3. The overlap according to claim 1, characterized by the fact that the deflecting carrier device is made in the form of a transverse profile sheet mounted on the end of the frame. 4. The overlap according to claim 1, on the basis of the fact that the step of arranging the regiments is made smaller than the step of arranging the trolleys in the train by at least half the intercarriage distance. 5. The overlap according to claim 1, characterized in that the chain circuits have tension mechanisms. r Mr. 4f-1 ) d / Yes Yes / 8/3 / $ No. /1 5 §TO Fig.Z
