Detailed Description

Example 1

As shown in fig. 1 and 2:

automatic loading device of a many swift current section of thick bamboo of train, including loading building 15, railway carriage 4, track and tractor 3, the tractor is connected its characterized in that with railway carriage 4: the leftmost end of the track is provided with a winch 1, the winch 1 is provided with an absolute value encoder 2, the absolute value encoder 2 is used for positioning the position of a train carriage 4, the upper part of the train carriage 4 is provided with a row of cover plates 9, a loading building 15 is provided with a group of accumulation scales 8, the lower part of each accumulation scale 8 is matched with a telescopic chute 7, the telescopic chute 7 is connected with a chute motor which is used for controlling the lifting of the telescopic chute, the winch 1 is connected with the lower part of a tractor 3 through a steel rope, the telescopic chute 7 is provided with a stay wire sensor 5 which is used for positioning the telescopic chute 7, the side edge of the telescopic chute 7 is provided with a laser distance measuring sensor 6, the loading building is also provided with a trowelling device which is positioned at the middle position of the train carriage 4, the trowelling device comprises a shell 12, a telescopic rod 13, a trowelling plate 14 and a lifting motor, the lifting motor is connected with the telescopic rod 13 to control the lifting of the, the voice broadcasting device 10 is installed outside the loading building 15 and used for voice prompt in the production process, and the vehicle code recognizer 11 is installed beside a track and used for automatically recognizing the serial number of the train carriage when the train carriage 4 passes through. Stay wire sensor 5, absolute value encoder 2, laser rangefinder sensor 6, voice broadcast ware 10, vehicle code recognizer 11, swift current section of thick bamboo motor, elevator motor, accumulative total 8 are connected with the PLC controller respectively, and laser rangefinder sensor 6 distributes in swift current 7 both sides or one survey. The using method of the invention is as follows: after the train carriage is stably stopped, the train carriage is well connected with the tractor, the current position of the train is read from the winch encoder after connection is confirmed, and after operation and judgment of the controller, the controller controls the winch to pull the tractor to drive the train to a fixed feeding position. The position of the sliding drum is judged by the pull wire sensor in the moving process of the train. The front sliding barrel can automatically ascend to a safe position in order to avoid scratching the train and move. After the train is in place, the sliding barrel is controlled to descend, and the descending position is confirmed by the stay wire sensor. When the train is stopped, the system determines whether the state of each scale is available. The controller internally distributes the expected loading total weight of each platform scale according to different conditions. After calculation in the controller, the weight of two tons per bucket is used as the weight of each scale, and the actual weight is read from the instrument after weighing is finished. The actual weight and the expected total weight of the truck load are calculated in the controller. And weighing is started after the weight distribution is finished. The laser ranging sensor can measure the height of the material during each blanking process. And customizing the predicted height according to the position of the train, and controlling the tractor to push the train to advance by the controller after the preset height is reached. The controller will read the data from the meter for each next bucket of material, perform calculations, and redistribute the weight according to the remaining weight when weighing the last bucket. And after the last bucket is finished, loading the next carriage. Abnormal states such as material blockage, material shortage and the like occur in the operation: the scale with the problem distributes the residual weight to other scales, and enters another circulation program for processing abnormal conditions to continuously finish loading. And stopping after loading is finished to wait for manual repair of the material shortage condition of the blocked material. And the next vehicle can be loaded continuously after manual confirmation. In order to achieve a better loading effect, a floating device is further arranged on a loading building, the floating device is located in the middle of a train carriage and comprises a shell, a floating plate, a telescopic rod and a lifting motor, the lifting motor is connected with the telescopic rod to control the lifting of the floating plate, when grains are to be filled, the telescopic chute is lifted firstly, then the lifting motor is started to place the floating plate into the train carriage to conduct floating operation on the grains in the carriage, after the floating is finished, the lifting motor is started to lift the floating plate, then the telescopic chute is lowered, and the grains are continuously loaded. The laser sensor is used for measuring the height of materials in the train carriage, the cone shape formed by the materials can be calculated by matching with the material repose angle, and the controller carries out loading logic decision according to the cone shape, so that the train moving distance and the blanking weight are controlled. The plurality of sensors can determine the profile of the material inside the railway carriage in real time. During the movement of the train, the laser sensor can detect the edge of the cover plate and is used for positioning calibration of the train.

The PLC controller and the central control room carry out data interaction, the central control room sends a loading task to the PLC controller, the PLC controller numbers the carriages in real time, and loading data of each carriage are transmitted to the central control room.

In the existing operation mode, the loading time of one carriage is about 9 minutes, the time is calculated by 16 carriages in a marshalling group, and the time for manually receiving a loading list, copying carriage numbers, positioning a train, moving the train and the like is generally more than 185 minutes. If the material is required to be leveled because the material is low in density or more impurities are required, the loading of a marshalling generally requires more than 240 minutes. By using the device, the loading time of each carriage is about 7 minutes, 16 carriages are grouped, after the train is in place, the system takes over until the loading is finished, generally 120 minutes are needed, the train needs to be leveled, and the loading of one group generally needs 150 minutes.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
