Description
Technical field
The utility model relates to a kind of chain and sprocket driving device of rock drilling machine parts, particularly a kind of rock drilling machine.
Background technology
During rock drill work, by feeding motor drive chain transmission device, chain and sprocket driving device pulls impactor to slide before and after the track of forward beam, thereby realizes the adjustment of the amount of feeding, and the hydraulic oil pipe that is connected with impactor also will be along with impactor slides.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 that drives is connected on the fixed point of forward beam, and the problem of existence is:
Because the sliding scale of impactor is larger, in order to guarantee that impactor is from the oil pipe fixed point farthest the time, oil pipe is not in tensioned state, oil pipe must have enough length, and when impactor is nearest apart from the oil pipe fixed point, will cause oil pipe long and drop, make oil pipe be in suspension status, not only affect attractive in appearance and operation, and the pulling force of oil pipe tenesmus generation will affect the life-span of oil pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of chain and sprocket driving device that is wound around the rock drilling machine of governor motion with oil pipe, to overcome the existing above-mentioned deficiency of prior art.
for solving the problems of the technologies described above, the technical scheme that the utility model is taked 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 the forward beam front portion, the drive sprocket that is in transmission connection with CD-ROM drive motor is arranged on the 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 comprises that also oil pipe is wound around governor motion, described oil pipe is wound around the rear portion that governor motion is arranged on the mount pad I, comprise the mount pad II of can be under chain-driving sliding along the track of forward beam, front moving slot wheel, rear moving slot wheel and rolling wheel support, front moving slot wheel, rear moving 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 is walked around tightener sprocket successively, drive sprocket and rear moving 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 is walked around front moving slot wheel and is fixed on the front fixed support of forward beam, 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 utility model has following beneficial effect:
1. the chain and sprocket driving device due to a kind of rock drilling machine of the utility model is wound around governor motion with oil pipe, oil pipe is looped around on the rolling wheel support of oil pipe winding governor motion, one end is connected with impactor, the other end is fixed on forward beam, when the 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 that is looped around on rolling wheel support is also the same with chain, the rope that all is equivalent to 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 constant to the length sum between oil pipe and forward beam junction again from the impactor to the rolling wheel support, like this, the state that both had been unlikely to that oil pipe was in and tightens, there is no unnecessary oil pipe tenesmus yet, be unlikely to rock because of the 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, and oil pipe marshalling, compactness are 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 utility model is wound around governor motion, former and later two moving slot wheels have only been used, the sliding speed that namely realizes oil pipe winding governor motion is half of impactor sliding speed, make oil pipe just be looped around on rolling wheel support all the time, design science, simple in structure, cost is low, and is economical and practical.

The specific embodiment
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 the forward beam front portion, the drive sprocket 8 that is in transmission connection with CD-ROM drive motor is arranged on the 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 comprises that also oil pipe is wound around governor motion, described oil pipe is wound around the rear portion that governor motion is arranged on mount pad I 4, comprise the mount pad II 11 of can be under chain-driving sliding along the track of forward beam, front moving slot wheel 12, rear moving slot wheel 10 and rolling wheel support 7, front moving slot wheel 12, rear moving 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 is walked around tightener sprocket 1 successively, drive sprocket 8 and rear moving 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 is walked around front moving slot wheel 12 and is fixed on the front fixed support 14 of forward beam, oil pipe 6 one ends are connected with impactor, and its other end is walked around rolling wheel support 7 after by support 5 and is fixed on front fixed support 14, then connects with oil circuit.
Operating principle:
When drive sprocket 8 rotates, chain drive-belt 2, impactor 3, driven chain 13 and the accompany movement of mount pad II are got up, because the mount pad II is equipped with forward and backward moving slot wheel, its effect is equivalent to a movable pulley, so no matter drive sprocket 8 forwards are still reversed, the movement velocity of impactor 3 all equals 2 times of rolling wheel support 7.Because oil pipe 6 one ends are 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 all just is looped around above rolling wheel support 7, has not both had the oil pipe of unnecessary length to fall, and also is unlikely to make oil pipe to be in tensioned state.
The effect of tightener sprocket 1 is the elasticity of adjusting chain, and is more smooth and easy when making chain drive.
