Description

Technical Field

[0001] This utility model belongs to the field of railway freight yard material loading and unloading technology, specifically relating to an integrated machine for picking up, unloading and cleaning materials in railway freight yards. Background Technology

[0002] Unloading coal in railway freight yards mainly involves grab bucket unloading, material placement, and warehousing, which is inefficient and environmentally unfriendly. Alternatively, single-unit unloading machines, cleaning machines, and material reclaimers can be used in a cyclical manner, but this is costly and takes up a lot of space for the freight yard.

[0003] Chinese patent CN201720508302.9 discloses a double vertical spiral unloading machine, which improves unloading efficiency, but the subsequent cleaning still requires a special cleaning machine. Therefore, it requires at least two sets of equipment: an unloading machine and a cleaning machine, which is costly.

[0004] Chinese patent CN201620810855.5 discloses a wagon cleaning machine that can clean up the remaining material in the wagon compartment after unloading. However, to complete the entire unloading process, it needs to be used in conjunction with an unloading machine. This means that separate cleaning and unloading machines would increase equipment costs, space occupation, and make the process cumbersome.

[0005] Therefore, how to provide an integrated material handling, unloading, and cleaning machine suitable for railway freight yards is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides an integrated material handling, unloading and cleaning machine suitable for railway freight yards, which combines the functions of unloading machine, cleaning machine and material handling machine, making it multi-functional, reducing cost, saving space and being convenient to use.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an integrated material handling, unloading, and cleaning machine suitable for railway freight yards, comprising:

[0008] A mobile support frame that travels on a track on the side of a railway freight yard or coal shed, and the mobile support frame is equipped with a horizontal sliding rail.

[0009] A cleaning mechanism assembly, which travels on the slide rail, is used to clean up the remaining material in the car after unloading;

[0010] An unloading mechanism assembly that travels on the slide rail and is used to unload materials from railway transport cars, and is also used to retrieve materials from the stockyard;

[0011] The feeding mechanism is horizontally arranged on the movable support frame and located on the travel path of the cleaning mechanism assembly and the unloading mechanism assembly. The feeding mechanism is used to receive and transfer materials sent by the cleaning mechanism assembly and / or the unloading mechanism assembly. The feeding mechanism is provided with multiple telescopic discharge ports on the feeding mechanism and corresponding to the feeding path. Each telescopic discharge port is provided with an electrically controlled gate.

[0012] The beneficial effects of this utility model are: the mobile support frame can span the entire freight yard when in use, and the cleaning mechanism assembly and unloading mechanism assembly on it are used to complete the unloading and cleaning process. The unloading mechanism assembly can also be used for the material retrieval process in the stockyard. The feeding mechanism is used to connect the materials sent by the cleaning mechanism assembly and the unloading mechanism assembly. The feeding mechanism has multiple telescopic discharge ports, and the specific unloading position can be determined according to the opening and closing of the electric control gate. It can be used in the stockyard or the discharge conveyor. In specific use, it is not limited to unloading materials from railway transport cars into the freight yard, but can also guide materials from the freight yard to the external discharge conveyor. It is suitable for a variety of use scenarios, is multi-purpose, saves equipment space and reduces the supporting costs of the freight yard.

[0013] Preferably, the movable support frame is a bridge frame or a gantry frame, and the movable support frame is equipped with a motor-driven walking wheel assembly.

[0014] The resulting technical effect is that the mobile support frame has a large span and relies on the traveling wheel assembly to move on the track and change the working position.

[0015] Preferably, the cleaning mechanism assembly includes a sweeping trolley, a bucket elevator, a bucket elevator lifting assembly, and a sweeping head. The sweeping trolley travels on the slide rail. The bucket elevator is slidably connected to the sweeping trolley. The bucket elevator lifting assembly is installed on the sweeping trolley and causes the bucket elevator to rise and fall. The sweeping head is connected to the bottom feed port of the bucket elevator. The top of the bucket elevator is provided with a discharge port, which is connected to the feeding mechanism for feeding.

[0016] The resulting technical effect is that the sweeping trolley can automatically move on the slide rail, and the bucket elevator, in conjunction with the sweeping head, can complete the sweeping and collection of the remaining material in the transport compartment and send it to the feeding mechanism for transport upstream and downstream.

[0017] Preferably, a telescopic discharge cylinder is connected to the discharge port, and the bottom end of the telescopic discharge cylinder is connected to the feeding mechanism.

[0018] The resulting technical effect is that, since the bucket elevator moves along with the sweeping trolley, it also needs to move up and down. Therefore, a telescopic discharge cylinder is installed. It should be noted that the bottom of the telescopic discharge cylinder is not fixed to the feeding mechanism. It can be suspended in the air or slidably connected above the feeding mechanism to avoid affecting the operation of the sweeping trolley.

[0019] Preferably, the bucket elevator assembly includes a lifting power unit and a guide frame. The guide frame is fixed on the sweeping mobile trolley, and the bucket elevator is slidably connected to the guide frame. The lifting power unit causes the bucket elevator to rise and fall.

[0020] The resulting technical effect is that the bucket lifting assembly is used to lift and guide the bucket elevator, thereby controlling the lifting and lowering position of the sweeping head.

[0021] Preferably, the unloading mechanism assembly includes an unloading trolley, a lifting slide, a vertical screw mechanism, and a feeding mechanism. The unloading trolley travels on the slide rail, the lifting slide is slidably connected to the unloading trolley, the vertical screw mechanism is mounted on the lifting slide, the feeding mechanism is mounted at the bottom inlet of the vertical screw mechanism, and a material transfer chamber is connected between the discharge end of the vertical screw mechanism and the feeding mechanism.

[0022] The resulting technical effect is that the unloading trolley moves on the slide rail, and the vertical screw conveyor and feeding mechanism on it are lifted and lowered based on the lifting slide. The feeding mechanism can feed the bulk material into the vertical screw conveyor, and then the material is sent from the vertical screw conveyor to the feeding mechanism to complete the subsequent material conveying.

[0023] Preferably, the feeding mechanism is rotated to adjust the feeding direction, and a storage yard and / or discharge conveyor are located below the telescopic discharge port on the feeding mechanism.

[0024] The resulting technical effect is that the feeding mechanism can adjust the feeding direction, which can complete the feeding of materials into the yard and the unloading of materials from the storage yard.

[0025] Preferably, the feeding mechanism is a scraper feeder, a screw feeder, or a belt conveyor.

[0026] The resulting technical effect is that the feeding mechanism has various forms, and it completes the material discharge by telescopic discharge port on the feeding path. Of course, the specific material discharge is controlled by an electric valve, thereby realizing the discharge of material to the target area. Attached Figure Description
