Problems solved by technology
[0003] In actual use, since the coal retaining plate is spliced by multiple steel plates, the upper plane where the two steel plates are spliced may not be on the same plane, which will cause the track trolley moving on it to be stuck. The connecting rod connecting the track trolley and the shearer is bent, which makes the coal rock identification device unusable

Embodiment Construction
[0024] Such as figure 1 , 2 , 3, 4, and 5, the right end of the connecting rod 2 is connected with the fixed seat 1 through the joint bearing 13, the left end of the connecting rod is connected with the camera connecting seat 3, and the device is connected with the shearer through the fixed seat, and the shearer video The camera used for collecting is fixedly installed on the camera connecting seat. Since the joint bearing 13 is used to connect the connecting rod and the fixed seat, the connecting rod can swing up, down, left, and right relative to the fixed seat within a certain range, which can eliminate the position difference between the shearer and the coal baffle during operation. The camera shakes.
[0025] The upper end of the lead screw 4 is fixed on the bottom surface of the camera connection seat, the lower end of the lead screw passes through the intermediate connection plate 7 and is matched with the nut fixed on the intermediate connection plate, and is install...

The invention relates to a video capture connecting device for a coal mining machine. The video capture connecting device comprises a video camera and a track trolley for installing the video camera,wherein the track trolley is connected with the coal mining machine through a connecting rod. The video capture connecting device is characterized in that one end of a connecting rod is connected witha fixed seat through a joint bearing; the fixed seat is connected with the coal mining machine; the other end of the connecting rod is connected with a video camera connecting seat; the upper end ofa lead screw is fixed on the bottom surface of the video camera connecting seat; the lower end of the lead screw penetrates through an intermediate connecting plate and is matched and connected with anut which is fixed on the intermediate connecting plate; a fixed ring is arranged at the middle part of the lead screw between the intermediate connecting plate and the video camera connecting seat;two ends of a fixed tightening device are respectively connected with the fixed ring and the intermediate connecting plate; a damping device is arranged between the track trolley and the intermediateconnecting plate. The video capture connecting device disclosed by the invention has the characteristics of reasonable structure, high reliability and the like; the stuck or derailment of the track trolley can be effectively avoided, trafficability characteristic and damping property of the track trolley are improved, and the quality of shooting picture of the video camera is ensured.
Description
technical field [0001] The invention relates to a connection device, in particular to a video acquisition connection device for a coal mining machine. Background technique [0002] At present, during the coal mining process, the underground shearer is adjusted at any time through the observation of the mining situation and the mining position of the shearer drum by the personnel on the mining site, which will cause the low working efficiency of the shearer and the labor of the operator. Due to problems such as high strength and poor working environment, an invention patent application named "Video Analysis and Control System for Coal Shearers" was published on February 23, 2018. The technical solution of this application is to install a coal rock identification device on the shearer. The coal and rock identification device is installed on the track trolley, which is connected to the shearer through the connecting rod, and the track trolley runs on the coal retaining plate. T...
