Problems solved by technology
[0004] Due to the mining of barren hills, the landform is complex, and it is difficult to ensure the levelness of the two tracks when laying long-distance tracks. As a result, the lifting saw machine or the walking track frame on which a certain track wheel hangs in the air, causing the machine to appear Slipping will increase the cutting resistance of the saw blade, and the roughness of the cut stone surface will be poor, which will affect the product quality and increase the workload of post-finishing

Embodiment Construction
[0027] refer to figure 1 , figure 2 , image 3 and Figure 4 , the legend is a track frame type quarry machine, including a lifting saw machine 1, a machine base 2, a track wheel 21 installed on the four corners of the machine base 2, a track frame 3, a pair of main rails 4 laid on the mine, the track Two rails 31 are installed on the frame 3, and the base 2 carrying the lifting saw machine 1 can be laterally displaced on the two rails 31 relative to the two main rails 4, and the cutting position can be changed to meet the requirement of cutting once the main rail 4 is laid. Multiple stone seams; and the track frame 3 walks along the main track 4 to complete the cutting operation of each stone seam. The machine base 2 and the track frame 3 are respectively provided with driving power to provide moving power.
[0028] One end shaft of the machine base 2 is positioned with a drive shaft 5, the drive shaft 5 includes an intermediate shaft 51 and a gear shaft 53 connected by ...

The invention relates to a gapless driving device of a quarrying machine, comprising a machine base, rail wheels and driving power, wherein the machine base carries a rise and falling saw; and the rail wheels are arranged in four corners of the machine base. The gapless driving device of the quarrying machine is characterized in that a drive shaft is in shaft locating on one end of the machine base; driving gears are respectively fixed on both ends of the drive shaft and meshed with racks arranged on rails; the both ends of the drive shaft are respectively sleeved with bearing sleeves; longitudinal springs are arranged between the machine base and the bearing sleeves and press the driving gears towards the racks all the time; the drive shaft is provided with a speed reducer; and the driving power is connected with the speed reducer in a transmission way. The invention adopts a shaft-locating dynamic structure between the drive shaft and the machine base, enables the driving gears to be mashed with the racks fixed on the rails without gaps under the action of the longitudinal springs and ensures the requirements of driving reliability and cutting accuracy without influencing the walking of a cutting saw even if partial rail wheels are suspend in midair, thereby enabling cut stone cracks to be smooth and reducing the cutting resistance of saw bits.
Description
Technical field: [0001] The invention belongs to the field of machinery, in particular to a driving device for a quarry machine to move without gaps. Background technique: [0002] Disclosed two kinds of mine quarrying machine settings in the patent bulletin, announcement number is CN2512909Y, the patent called mine quarry machine, and announcement number is CN2613588Y, a kind of stone block material mining equipment by name, both all include possible The lifting saw machine that walks on a pair of equal tracks, the former saw machine is driven up and down by hydraulic cylinder, and the latter uses the structure of screw rod to drive the wire block to drive the saw machine up and down. The lifting saw machine walks on a pair of parallel rails, which can directly cut out stone crevices in the mine, and the lifting of the saw machine can complete the cutting operation from shallow to deep. The above-mentioned equipment has created a new method of mining barren mountain ore, w...
