Description

Technical Field

[0001] The utility model belongs to the technical field of open car cleaning, in particular to a car bottom cleaning mechanism dedicated to C-type and O-type tipping machines. Background Art

[0002] An open wagon is a type of railway freight car. It is characterized by being uncovered and having side panels on four sides, with two side panels having openable side doors for easy unloading of goods. Coal is mainly transported by open wagons, and unloading is usually done by a dumper. As coal accumulates during transportation, it is inevitable that it will adhere to the bottom of the wagon, so the remaining coal needs to be cleaned.

[0003] Most of the existing cleaning methods use manual cleaning or cleaning machines. Whether it is manual cleaning or cleaning machine cleaning, it is necessary to wait until the unloading is completed before cleaning, which increases the cleaning process of the open car and reduces the work efficiency. In addition, it is necessary to purchase a special open car cleaning machine, which increases the cost of the enterprise. Utility Model Content

When the open mouth of the open car compartment faces left, the right end of the bottom of the open car compartment begins to be exposed, and the counterweight block droops due to its own weight, driving the limit rod to separate from the fixed column, and a number of nozzles rotate and face the bottom of the open car compartment. A number of nozzles begin to spray water to wash and clean the right end of the bottom of the open car compartment. Then, the tipper drives the open car compartment to continue to rotate counterclockwise to unload, and a number of nozzles remain stationary. When the open mouth of the open car compartment faces downward, the material is unloaded, and a number of nozzles complete the washing and cleaning of the bottom of the open car compartment from the right end to the left end. A number of nozzles stop spraying water. Finally, the tipper drives the open car compartment to rotate clockwise to reset. When the fixed column rotates to the upper side of the washing pipeline, the fixed column and the limit rod are abutted again.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model utilizes the process of a car tipper turning over an open car compartment to unload materials, and washes and cleans the bottom of the open car compartment. Initially, the washing pipeline rotates with the open car compartment, and a number of nozzles do not spray water to prevent the material from being too wet. As the material is continuously discharged from the compartment, when the right end of the bottom of the open car compartment begins to be exposed, a number of nozzles on the washing pipeline begin to spray water to wash and clean the bottom of the open car compartment. During the washing process, a counterweight is used to keep the washing pipeline balanced and motionless. As the car tipper drives the open car compartment to continue to rotate and unload materials, while all the materials are unloaded, the cleaning bottom mechanism also completes the cleaning of the bottom of the open car compartment. There is no need to clean the open car compartment after unloading, and the operation efficiency is high without requiring additional labor and equipment costs.

[0015] 2. When the electromagnetic clutch is disengaged, the flushing pipeline is disconnected from the output shaft of the reduction motor, and the flushing angle of the flushing pipeline is controlled by the counterweight. When the electromagnetic clutch is engaged, the flushing pipeline and the output shaft of the reduction motor are connected through the electromagnetic clutch. The reduction motor can forcibly control the rotation of the flushing pipeline, thereby controlling the flushing angles of several nozzles. The working conditions of the electromagnetic clutch and the reduction motor can be controlled manually on site or remotely by PLC. Several cameras are used to observe the residual material on the bottom of the open car compartment, so as to focus on flushing specific parts and angles through the flushing pipeline and video monitoring.
