Description
Technical field
The present invention relates to a kind of rock drilling machine parts, particularly a kind of chain and sprocket driving device of rock drilling machine.
Background technology
By feeding motor drive chain transmission device during rock drill work, chain and sprocket driving device pulls impactor along the track slide anteroposterior of forward beam, thus realizes the adjustment of the amount of feeding, and the hydraulic oil pipe be connected with impactor also will slide along with impactor.Original chain and sprocket driving device does not have oil pipe to be wound around governor motion, and its hydraulic oil pipe other end of the impactor driven is connected on the fixed point of forward beam, and Problems existing is:
Because the sliding scale of impactor is larger, in order to ensure impactor from oil pipe fixed point farthest time, oil pipe is not in tensioned state, oil pipe must have enough length, and when impactor distance oil pipe fixed point is nearest, oil pipe will be caused long and drop, and making oil pipe be in suspension status, not only affect attractive in appearance and operation, and the pulling force that oil pipe tenesmus produces will affect the life-span of oil pipe.
Summary of the invention
The object of the present invention is to provide a kind of chain and sprocket driving device being wound around the rock drilling machine of governor motion with oil pipe, to overcome the above-mentioned deficiency existing for prior art.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of chain and sprocket driving device of rock drilling machine, comprise forward beam, impactor, pull the chain of impactor, tightener sprocket and drive sprocket, tightener sprocket is arranged on forward beam front portion, the drive sprocket be in transmission connection with CD-ROM drive motor is arranged on forward beam rear portion, impactor is arranged on the mount pad I that can slide along the track of forward beam, described chain and sprocket driving device also comprises oil pipe and is wound around governor motion, described oil pipe is wound around the rear portion that governor motion is arranged on mount pad I, comprising can along the mount pad II that the track of forward beam slides under chain-driving, front dynamic slot wheel, rear dynamic slot wheel and rolling wheel support, front dynamic slot wheel, rear dynamic slot wheel is arranged on mount pad II bottom, rolling wheel support is arranged on mount pad II top, the described chain of impactor that pulls comprises chain drive-belt and driven chain, one end of chain drive-belt is connected to the front end of mount pad I, the other end walks around tightener sprocket successively, drive sprocket and rear dynamic slot wheel are fixed on the rear fixed support of forward beam, one end of driven chain is connected to the rear end of mount pad I, and the other end moves slot wheel and is fixed on the front fixed support of forward beam before walking around, oil pipe one end is connected with impactor, and its other end is walked around rolling wheel support by support and is fixed on front fixed support.
Owing to taking technique scheme, the chain and sprocket driving device of a kind of rock drilling machine of the present invention has following beneficial effect:
1. because the chain and sprocket driving device of a kind of rock drilling machine of the present invention is wound around governor motion with oil pipe, oil pipe is looped around oil pipe and is wound around on the rolling wheel support of governor motion, one end is connected with impactor, the other end is fixed on forward beam, when chain-driving impactor slides, the mount pad II that oil pipe is wound around governor motion is equivalent to a movable pulley, chain is equivalent to the rope of hoisting movable pulley, impactor is connected on the free end of chain, so the sliding speed of impactor is 2 times of mount pad, and the oil pipe be looped around on rolling wheel support is also the same with chain, all be equivalent to the rope of hoisting movable pulley.So, no matter which position impactor slides into, oil pipe is looped around on rolling wheel support all the time just, namely from impactor to rolling wheel support again to the length sum between oil pipe and forward beam junction be constant, like this, the state being both unlikely to that oil pipe was in and tightening, unnecessary oil pipe tenesmus is not had yet, be unlikely to rock because of oil pipe tenesmus, make oil pipe be subject to extra pulling force, affect the life-span of oil pipe.
2. because no matter which position impactor slides into, oil pipe is looped around on rolling wheel support all the time just, oil pipe marshalling, compact, both attractive in appearance, can not affect operation again.
3. the oil pipe of the chain and sprocket driving device of a kind of rock drilling machine of the present invention is wound around governor motion, former and later two dynamic slot wheels are only used, namely the sliding speed realizing oil pipe winding governor motion is the half of impactor sliding speed, oil pipe is looped around on rolling wheel support all the time just, design science, structure is simple, and cost is low, economical and practical.

Detailed description of the invention
A kind of chain and sprocket driving device of rock drilling machine, comprise forward beam 15, impactor 3, pull the chain of impactor, tightener sprocket 1 and drive sprocket 8, tightener sprocket 1 is arranged on forward beam front portion, the drive sprocket 8 be in transmission connection with CD-ROM drive motor is arranged on forward beam rear portion, impactor 3 is arranged on the mount pad I 4 that can slide along the track of forward beam, described chain and sprocket driving device also comprises oil pipe and is wound around governor motion, described oil pipe is wound around the rear portion that governor motion is arranged on mount pad I 4, comprising can along the mount pad II 11 that the track of forward beam slides under chain-driving, front dynamic slot wheel 12, rear dynamic slot wheel 10 and rolling wheel support 7, front dynamic slot wheel 12, rear dynamic slot wheel 10 is arranged on mount pad II bottom, rolling wheel support 7 is arranged on mount pad II top, the described chain of impactor that pulls comprises chain drive-belt 2 and driven chain 13, one end of chain drive-belt 2 is connected to the front end of mount pad I 4, the other end walks around tightener sprocket 1 successively, drive sprocket 8 and rear dynamic slot wheel 10 are fixed on the rear fixed support 9 of forward beam, one end of driven chain 13 is connected to the rear end of mount pad I 4, and the other end moves slot wheel 12 and is fixed on the front fixed support 14 of forward beam before walking around, oil pipe 6 one end is connected with impactor, and its other end is fixed on front fixed support 14, then connects with oil circuit by walking around rolling wheel support 7 after support 5.
Operating principle:
When drive sprocket 8 rotates, chain drive-belt 2, impactor 3, driven chain 13 and mount pad II accompany movement are got up, because mount pad II is provided with forward and backward dynamic slot wheel, its effect is equivalent to a movable pulley, so no matter drive sprocket 8 rotates forward or reversion, the movement velocity of impactor 3 all equals 2 times of rolling wheel support 7.Because oil pipe 6 one end is connected on impactor 3, then be looped around on rolling wheel support 7, the other end is connected on front fixed support 14, and the movement velocity of impactor 3 equals 2 times of rolling wheel support 7, so no matter where impactor 3 moves to, oil pipe 6 is all just looped around above rolling wheel support 7, has not both had the oil pipe of additional length to fall, and is also unlikely to make oil pipe be in tensioned state.
The effect of tightener sprocket 1 is the elasticity of adjusting chain, more smooth and easy when making chain drive.
