The electric bolt 51 is fixedly arranged on the main frame 1, and the swing frame 21 is provided with a hole which is matched with the electric bolt 51. When the telescopic driving mechanism 3 drives the swing frame 21 to swing to the first limit position, the position of the hole corresponds to the electric bolt 51, and the electric bolt 51 is inserted into the hole to avoid the swing frame 21 from falling accidentally.

[0081] It can be understood that, in the embodiment, the anti-falling mechanism 5 can also be a hook fixed on the main frame 1 and matched with the insertion hole, or can also be a drag plate or a drag rod fixed on the main frame 1 and arranged in an extendable manner, and the above implementation manners can all achieve the purpose of avoiding the accidental falling of the swing frame 21 in the embodiment.

[0082] The novel hydraulic flat coal system provided in the embodiment of the utility model, like Figure 1 As shown, further include the anti-collision mechanism;The anti-collision mechanism is electrically connected with the telescopic drive mechanism 3, and the anti-collision mechanism is used to monitor the position information of the scraper mechanism 22;The telescopic drive mechanism 3 drives the swing frame 21 to rotate around its rotation center according to the monitoring information of the anti-collision mechanism.

[0083] Preferably, the novel hydraulic flat coal system further includes an anti-collision mechanism to avoid collision between the scraper mechanism 22 and the carriage. When in use, the anti-collision mechanism is used to monitor the position information of the scraper mechanism 22, and when the scraper mechanism 22 is about to collide with the carriage, the anti-collision mechanism feeds back information to the telescopic drive mechanism 3, and the telescopic drive mechanism 3 drives the swing frame to swing so that the scraper mechanism 22 moves away from the carriage.

[0084] Optionally, in the embodiment, the anti-collision mechanism can be mechanical anti-collision or electrical anti-collision;When the anti-collision mechanism is mechanical anti-collision, the anti-collision mechanism includes a shear type anti-collision sensor or a proximity switch, and when it is detected that the scraper mechanism 22 is too close to the carriage, the telescopic drive mechanism 3 acts in time to make the scraper mechanism 22 move away from the carriage;When the anti-collision mechanism is electrical anti-collision, the anti-collision mechanism includes a beacon assembly 61, and the beacon assembly 61 is arranged upstream of the main frame 1, and the beacon assembly 61 determines the limit position of the scraper mechanism 22 in combination with the model information of the carriage, and when the limit position is triggered and the scraper mechanism 22 does not act, the telescopic drive mechanism 3 acts in time to make the scraper mechanism 22 move away from the carriage. Preferably, the anti-collision mechanism simultaneously adopts mechanical collision and electrical collision, and the electrical collision is preferably used instead of the mechanical collision to avoid frequent replacement of the shear type anti-collision sensor.

[0085] The novel hydraulic flat coal system provided in the embodiment further includes an operation room arranged on the main frame 1, which is used for manual intervention in the operation of the novel hydraulic flat coal system. A video monitoring system can also be arranged on the main frame 1 to realize remote monitoring and abnormal action alarm functions.

[0086] In the description of the utility model, it is necessary to explain, the direction or position relation that the term "upper", "lower" and the like indicate is based on the direction or position relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and is not indicate or imply that the device or element indicated must have a particular orientation, construct and operate in a particular orientation, therefore can not be understood as the limitation of the utility model. In addition, the term "first", "second" is only for the purpose of description, and can not be understood as indicating or implying relative importance.

[0087] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, the term "installation", "communication", "connection" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be direct communication, also can be indirectly communicated through the intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances. In addition, in the description of the utility model, unless otherwise stated, the meaning of "multiple" is two or more than two.

[0088] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
