DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will further describe the present invention with reference to accompanying drawings.

[0032] A movable loading machine with a twin telescopic boom structure includes a head wagon 1 and a tail wagon 2, the tail wagon 2 is connected to the head wagon 1 via a traction pull rod, and a dual-stage triple-channel forked hopper 3 and a twin telescopic boom 4 are mounted on the head wagon 1.

[0033] The twin telescopic boom 4 is a main wagon loading boom 41 and an auxiliary wagon loading boom 42 mounted in parallel, the main wagon loading boom 41 and the auxiliary wagon loading boom 42 both are booms with telescopic function, the main wagon loading boom 41 and the auxiliary wagon loading boom 42 each is provided with a belt conveyor and an electronic belt scale. During a loading operation, the twin telescopic boom stretches out to the above of the wagon. When it is not in a loading operation, the twin telescopic boom retracts beyond a railway construction clearance, and thus it does not prevent a locomotive from passing through.

[0034] The dual-stage triple-channel forked hopper 3 includes an upper-stage forked hopper 31 and a lower-stage forked hopper 32, the upper-stage forked hopper 31 and the lower-stage forked hopper 32 both have three channels, namely a main wagon loading channel 33, an auxiliary wagon loading channel 34 and a recovery channel 35, where the main wagon loading channel 33 is connected to the main wagon loading boom 41 and the auxiliary wagon loading channel 34 is connected to the auxiliary wagon loading boom 42; and the upper-stage forked hopper 31 and the lower-stage forked hopper 32 each is internally provided with a reversing device, which may distribute material into different channels according to different needs.

[0035] The head wagon 1 includes a head wagon steel structure 11, an upper part of the head wagon steel structure 11 is provided with a driver control room 12 and a low-voltage electrical room 13, a bottom part of the head wagon steel structure 11 is provided with a walking drive device 14, and the main wagon loading boom 41 and the auxiliary wagon loading boom 42 are respectively mounted on the head wagon steel structure 11.

[0036] The tail wagon 2 includes a tail wagon steel structure 21 designed with a ramp structure, the ramp of the tail wagon steel structure 21 is provided with a carrier roller for ground belt running, a lower part of the tail wagon steel structure 21 is connected with a high voltage power supply device 22, a high-voltage electrical room 23, and a dustproof antifreezing sprinkler 24, and a top end of the ramp of the tail wagon steel structure 21 is provided with a belt bend pulley 25 positioned above the upper-stage forked hopper 31. To-be-loaded materials are conveyed, along the ramp by a ground belt, to the top of the tail wagon, and falls, by means of the belt bend pulley 25, into the upper-stage forked hopper 31.

[0037] The front end of the main wagon loading boom 41 and of the auxiliary wagon loading boom 42 each is provided with a material dropping funnel which is used to evenly and stably load materials in the booms into a wagon.

[0038] The rear part of the main wagon loading boom 41 is provided with a flattening device, which may automatically make the material even while loading in the process of loading. And the flattening device and the material dropping funnel constitute a front-end material discharge device 5. Due to adoption of the design of the twin telescopic boom, the front-end blanking device 5 does not have the function of material distribution any more, thereby the size is greatly reduced, and the front-end material discharge device 5 has a height 2 m, which meets the requirement for space between an electrified overhead contact system and an upper edge of any domestic open wagon.

[0039] Working Process:

[0040] 1. A to-be-loaded train parks on a loading line, and the twin telescopic boom 4 stretches out to the front-end material discharge device 5 and is positioned above a box of an open wagon.

[0041] 2. Materials are conveyed, along the ramp of the tail wagon steel structure 11 by a ground belt conveyor, to the tail wagon 2, and falls, by means of the belt bend pulley 25, into the dual-stage triple-channel forked hopper 3. A driver controls the reversing device in the dual-stage triple-channel forked hopper 3 to convey materials to the main wagon loading channel 33; the materials fall into the main wagon loading boom 41, and are conveyed by a belt conveyor mounted on the main wagon loading boom 41 to the front-end material discharge device 5 and are finally loaded into the wagon carriage. A belt scale on the main wagon loading boom 41 meters, in real time, the weight of materials passing through the boom. In order to ensure that the materials are uniformly distributed in the wagon, the loading machine automatically controls the driving speed of the loading machine according to a rated loading capacity of the open wagon to ensure that the main wagon loading boom 41 is located at the tail end of the wagon when the wagon is fully loaded, and that the auxiliary wagon loading boom 42 is located at the head end of a next wagon.

[0042] 3. When the present wagon is fully loaded and a bridge connection is needed, the driver controls the reversing device in the dual-stage triple-channel forked hopper 3 to convey materials to the auxiliary wagon loading channel 34, and the materials are loaded into the next wagon by a belt conveyor on the auxiliary wagon loading boom 42, thereby implementing continuous feed of materials in case of a wagon bridge connection, and ensuring that no material is scattered at a wagon connection joint.

[0043] 4. As the loading machine moves forward, when the main wagon loading boom 41 is exactly above the next wagon, the driver controls the reversing device in the dual-stage triple-channel forked hopper 3 to switch the materials into the main wagon loading channel 33 again, so that the main wagon loading boom 41 continues finishing the loading operation of the wagon. The foregoing actions are repeatedly performed until the loading operation of the whole train is completed.

[0044] 5. After the loading operation is completed, if the ramp of the tail wagon steel structure 11 still has some surplus materials, the driver may switch the reversing device in the dual-stage triple-channel forked hopper 3 to distribute the surplus materials to the recovery channel 35, and the surplus materials fall via the recovery channel 35 onto the ground belt conveyor and finally return to material yard. After all the operations are completed, the twin telescopic boom 4 retracts beyond a railway construction clearance, thereby ensuring a railway locomotive to pass through.
