TRAIN BULK CARGO LOADING SYSTEM HAVING DISCONNECTED RAILROAD TRACK SCALE

Abstract

A train bulk cargo loading system having a disconnected railroad track scale, includes a disconnected railroad track scale (1), a tractor (2), a lifting scraping plow (4), a controllable vibration charging hopper (6), a surge bin (8), a belt conveyor (9) and a control terminal (7). The train bulk cargo loading system having the disconnected railroad track scale has a low overall height and a small footprint, thus reducing the construction and production costs. The system integrates loading, trimming, measuring and data sharing, and features uniform loading, balanced train wheel pressure, and accurate measuring. Thus, huge human and material resources consumption caused by uneven loading of an original loading system, large wheel pressure deviation and secondary trimming and measuring required by the railway department may be avoided, significantly reducing the construction cost and operation cost.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the embodiments of the present disclosure or the technical solution in the prior art, the drawings required in the embodiments or description of the prior art will be briefly described below. It will be apparent that the drawings in the following description are only some embodiments of the present disclosure. For those of ordinary skill in the art, other drawings can be obtained according to these drawings without creative effort.

[0013] FIG. 1 is a schematic diagram of the overall structure of the present disclosure.

DETAILED DESCRIPTION

[0014] All the features disclosed in this specification, or all steps in any method or process disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.

[0015] Any feature disclosed in this specification (including any accompanying claims, abstract, and drawings) may be replaced by other equivalent or similar alternative features serving the same purpose, unless specifically stated otherwise. That is, unless specifically stated, each feature disclosed is only one example of a generic series of equivalent or similar features.

[0016] As shown in FIG. 1, a train bulk cargo loading system having a disconnected railroad track scale includes a disconnected railroad track scale 1, a tractor 2, a cargo train 3, a lifting scraping plow 4, a charging hopper gate 5, a vibration charging hopper 6, a control terminal 7, a surge bin 8 and a belt conveyor 9. A plurality of disconnected railroad track scale 1 are mounted on a rail line. A charging hopper gate 5 having a controllable opening/closing gate is provided in a discharge opening of the vibration charging hopper 6. The discharge opening of the vibration charging hopper 6 is mounted at a lower part of the surge bin 8, and the discharge opening is aligned with a longitudinal center line of the cargo train 3. The lifting scraping plow 4 is mounted at the rear of the discharge opening, and the height of the scraping plow is controlled immediately after charging to perform trimming. The belt conveyor 9 is mounted on an upper part of the surge bin 8 to feed the surge bin. The tractor 2 is mounted at a front end of the cargo train 3. The control terminal 7 is mounted at an appropriate position.

[0017] The working process of the present disclosure is as follows. During loading operation, the control terminal starts the belt conveyor 9 to feed the surge bin 8. When the surge bin is fed to a set value, the tractor 2 is controlled to be started to pull the cargo train 3 forward. When wheels enter an area of the disconnected railroad track scale, the scale measures the deadweight of a train wagon. When a head of a carriage exceeds the discharge opening, the charging hopper gate 5 is controlled to open, and at the same time a vibrator of the vibration charging hopper 6 is activated to load the bulk material into the carriage. The control system sets a matching traction speed of the tractor 2 according to the weight of the loaded materials of the train through a pre-input program, to continue to pull the cargo train 3 forward, and the height of a head of the lifting scraping plow 4 is adjusted to perform trimming while the cargo train 3 advances. The railroad track scale 4 dynamically detects the measurement data and feeds it back to the control terminal 7 in time. The control terminal 7 calculates and controls an opening angle of the charging hopper gate 5, a travelling speed of the cargo train 3, and the plow head height of the lifting scraping plow 4 according to relevant parameters to ensure a uniform loading of the entire carriage. The total weight, tare weight, net weight and other data are recorded after each carriage is loaded. Because the specific gravity of materials for each shift and batch is different, and the parameters such as the opening angle of the discharging gate, the travelling speed of the cargo train, and the plow head height of the scraping plow are different, the control terminal 7 has an automatic learning and memory function, which records and memorizes the travelling speed of the cargo train, the opening angle of the charging hopper gate, and the plow head height of the scraping plow in real time, and applies them to the next carriage or the next group of trains. In addition, control terminal 7 makes immediate adjustment according to dynamic weighing data of the railroad track scale to ensure uniform loading, accurate measurement and loading efficiency, ensure a final uniform wheel pressure of the train and control the wheel pressure within the allowable range specified by the railway department.

[0018] As a preferred technical solution, the data of the control terminal 7 is transmitted to a background. Due to the accurate measurement and uniform loading, the data can be submitted to the government technical supervision department for examination and approval. The measurement data can be shared and used as a reference for cargo delivery and pricing of cargo owners, loading and unloading, transportation, railway and other parties, thus reducing the multiple measurement costs of the entire supply chain.

[0019] Compared with the traditional quantitative bin loading station, the train bulk cargo loading system having the disconnected railroad track scale has the following technical and economic characteristics:

[0020] 1. Great reduction of the overall height and floor area of the loading station, and reduction of the construction investment and operation cost of loading and measuring facilities;

[0021] 2. Avoidance of secondary loading and unloading, trimming and measuring links, obvious reduction of the labor intensity of loading and unloading workers and lowering of the labor cost;

[0022] 3. Completion of the measurement, loading and trimming in one step, thus reducing the operation links and improving the production efficiency; and

[0023] 4. Uniform loading, accurate measurement and sharing of measurement data, which may serve as a reference for the supervision, pricing and settlement of the entire supply chain to reduce multiple measurement links of the entire supply chain, thus reducing the total cost of the entire supply chain.

[0024] The above description is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and any changes or substitutions occurring to those skilled in the art without creative effort should be included within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be defined by the claims.
