DD246580A1 - CONTROL FOR THE UNLOADING PROCESS OF TRANSPORT VEHICLES FOR SHOE LOADERS - Google Patents

Abstract

The invention relates to a control for the unloading of trolley with Stetigfoerderern Schuettgueter, especially gravel, sand and ballast. The aim of the invention is to avoid additional Egalisierungsarbeiten and additional intermediate storage when introducing bulk material in the track area. The invention has for its object to provide for a provided with Stetigfoerderern transport vehicle for Schuettgueter a the unloading process during a non-continuous movement self-regulating control. According to the invention, this is achieved by assigning to the transport vehicle an influenceable by the rail fastening means of the track switching device, a timing relay and the motors of the Stetigfoerderer switching motor protection.

Description

the contacts 11 of the limit switch 10, the relay 12 is driven. The holding contacts of the relay 12 are closed via the timing relay 14 in the rest position, so that the relay 12 stops. Thus, the circuit for the timing relay 14 is closed when operating the limit switch 10 and this controls the motor contactors 15 and 16 at. Thus, the motors 17 and 18 are switched on for the scraper chain and the Abwurfband'. If the time relay 14 has expired, the motors 17 and 18 are switched off again. Since the holding contacts of the relay 12 are opened when switching the timing relay 14, the relay 12 drops. This prevents that after a switching operation immediately a new one is initiated, when the switching lever 4, the propulsion is interrupted or extremely slow

 After use, the system is de-energized by means of switch 13.

For this 1 page drawings. Field of application of the invention The invention relates to a control for the unloading process of rail-bound transport vehicles for bulk goods, in particular gravel, rock sand, gravel for metered depositing of the bulk material. Characteristic of the known technical solutions There are facilities known that promote bulk goods from a container with scraper chains and deposit the masses at the desired location on the track body via a pivotable discharge belt. Although a constant capacity is achieved by lowering the scraper chain, the amount deposited is different because the required feed rates can not be met by the locomotives. There are also known plants that store bulk materials on conveyor belts. The promotion per time unit is also adjustable here. However, the tray is also uneven for the sake of feed. Object of the invention. ·. It is the object of the invention to avoid subsequent Egalisierungsarbeiten after the introduction of bulk materials in a track and to save cache. Explanation of the essence of the invention The invention has for its object to provide for a transport vehicle for bulk goods with discharge conveyor installed continuous conveyors with preselected constant capacity a the unloading process during an uncontrolled movement automatically controlling control for the metered unloading. According to the invention, this is achieved by the transport vehicle, one of the rail fastening means of the track influenceable switching organ a timing relay and the drive motors of all participating in the discharge continuous conveyor for a predetermined, adjusted time in operation, in the for a threshold distance or for a sleeper compartment certain proportion of bulk material is stored. In a continuous and discontinuous driving speed as well as during breaks in the transport vehicle, this process is repeatable for each threshold field. embodiment The invention will be explained with reference to an embodiment. Show it: Fig. 1: the scheme of a transport vehicle for bulk materials
Fig. 2: the scheme of the control. A movable on a track 1 transport vehicle 2 is connected to a traction unit 3. Under the transport vehicle 2, a switching member is arranged, which consists of a lever 4 and a switch box 5. In the control box 5, a limit switch 10 is provided with bolts 6 in slots 7, which are held with tension springs 8 in a normal position, at the upper end of the lever 4, which contacts 11 contains. The operation of the limit switch 10 is effected by a Be'rührung the lever 4 with a rail fastening means. The limit switch 10 is a relay 12 and a timing relay 14 downstream, via the motor contactors 15; 16 with motors 17; 18 are connected. Another switch 13 is the power supply. When ancestors touched the lever 4, the rail mounting 9 and is folded so far back until it slips over them. During the lever movement, a pin 6 is pivoted to the axis of rotation and the other pin 6 lifts off. In this case, the spring 8 is stretched on this side and brings the lever 4 back to the starting position after the switching operation. By the pivoting of the lever 4, the limit switch 10 is pressed and initiated the electrical switching operation. In order to avoid switching errors during work interruptions, the control must be initiated again after each switching operation. This always happens when the lever 4 returns to its original position. By closing
