Abstract
The utility model discloses a chain drive unit of rock drill relates to hydraulic rock drill additional equipment technical field, the oil pipe that is connected including one end and impacter with drive the impacter do reciprocating motion from beginning to end both ends all with the drive chain that the impacter mount pad is connected, the after -fixing of gyro wheel support is walked around on propulsion - beam to the oil pipe other end, the gyro wheel support is driven by the climbing sprocket propulsion - beam makes reciprocating motion, climbing sprocket its upper portion with the drive chain meshing, its lower part meshing should be scrambleed the chain and fix on the climbing chain propulsion - beam is last, compares with prior art, the utility model discloses impacter which position of sliding no matter, oil pipe encircles all the time just on the gyro wheel, promptly, from the impacter to the gyro wheel support again to the length sum oil pipe and the propulsion - beam junction be unchangeable, like this, both do not had unnecessary oil pipe to drop, also be unlikely to to make oil pipe to be in the state of tightening.
Description
Technical field
This utility model relates to hydraulic gate auxiliary device technical field, the chain and sprocket driving device of a kind of rock drill.
Background technology
Hydraulic gate operationally, needs hydraulic oil to provide impulse force to impacter；When feeding motor drives chain, impacter slides up and down along forward beam under the pulling force of chain, and is connected with impacter for providing hydraulic oil pipe one end of hydraulic oil to be fixed on forward beam, the other end is along with impacter slip.Owing to the sliding scale of impacter is relatively big, in order to ensure that oil pipe is not at tensioned state, then it is necessary that oil pipe has enough length when impacter distance oil pipe fixing point is farthest.So, exist for following problem: when impacter distance oil pipe fixing point is nearest, owing to oil pipe is long and cause tenesmus so that oil pipe is in suspension status, not only affects attractive in appearance, and, oil pipe tenesmus produces certain pulling force, have impact on the life-span of oil pipe.Therefore, it is necessary to a kind of device of design, making oil pipe be looped around above, no matter which position impacter slides into, and tubing length is the most suitable, had both been not at tensioned state, and had not dropped because length is oversize.
Summary of the invention
Technical problem to be solved in the utility model is to provide the chain and sprocket driving device of a kind of rock drill making oil pipe not only be not at tensioned state but also do not drop because length is oversize.
In order to solve the problems referred to above, this utility model be the technical scheme is that to include the oil pipe that one end is connected and the driving chain that drive impacter is reciprocating and head and the tail two ends are all connected with described impacter mounting seat with impacter, the described oil pipe other end is fixed on forward beam after walking around rolling wheel support, and described rolling wheel support is driven reciprocating at described forward beam by climbing sprocket wheel；Described its top of climbing sprocket wheel is engaged with described driving chain, and its underpart is engaged on climbing chain, and this climbing chain is fixed on described forward beam.
In technique scheme, more specifically technical scheme is it may also is that described rolling wheel support is fixed in roller mounting seat, and described climbing sprocket wheel is fixed under described roller mounting seat by connecting shaft.
Further: described driving chain walks around the tightener sprocket being contained in described forward beam one end and the drive sprocket being contained in the described forward beam other end；Described climbing sprocket wheel is between described tightener sprocket and described drive sprocket.
Further: described impacter mounting seat is provided with the support for fixing described oil pipe, being integrally fixed on the fixed support that described forward beam is provided with of described oil pipe.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, it is connected with impacter due to one end of oil pipe, the other end is fixed on forward beam after walking around rolling wheel support, rolling wheel support is driven reciprocating at forward beam by climbing sprocket wheel, climbing sprocket wheel is by driving chain-driving to walk, therefore, no matter which position impacter slides into, oil pipe is all the time right around on roller, i.e., from impacter to rolling wheel support again to the length sum between oil pipe and forward beam junction be constant, so, both do not had unnecessary oil pipe to drop, and be unlikely to make oil pipe be in the state tightened yet.
2, after using drive mechanism of the present utility model, oil pipe not only arranges neatly, compact, attractive in appearance, and when following impacter and sliding up and down, is unlikely to rock because of oil pipe tenesmus, makes oil pipe be subject to extra pulling force, affect the life-span of oil pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enlarged drawing at the A of Fig. 1.
Detailed description of the invention
The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings:
The present embodiment as depicted in figs. 1 and 2, include oil pipe 6 and drive chain 2, one end of oil pipe 6 is connected with the support 5 of impacter 3, the other end is fixed on after walking around rolling wheel support 8 on the fixed support 12 on forward beam 13, rolling wheel support 8 is fixed in roller mounting seat 10, and roller mounting seat has climbing sprocket wheel 7 by connecting shaft connection 10 times；The one end driving chain 2 is fixed on the upper end of impacter mounting seat 4, the other end walks around the tightener sprocket 1 being located at forward beam 13 upper end and the drive sprocket 9 being located at forward beam 13 lower end, revolution is walked around the lower end of climbing sprocket wheel 7 and impacter mounting seat 4 and is fixed again, between the loop checking installation of drive sprocket, parallel it is provided with a climbing chain 11, climbing sprocket wheel 7 lower end is engaged on this climbing chain, and climbing chain 11 is fixed on forward beam.
When drive sprocket 9 rotates, chain 2 is driven to drive impacter 3 to move, owing to driving chain 2 and climbing sprocket wheel 7 to engage, climbing chain maintains static, so when driving chain 2 to move, climbing sprocket wheel 7 makees pure rolling on climbing chain 11, the o1 point of climbing sprocket wheel 7 is instantaneous center of velocity, due to o1o2=2oo1, so the speed of o2 point is equal to 2 times of the speed of o point, that is to say that the speed of impacter 3 is equal to 2 times of rolling wheel support 8.During work, rolling wheel support 8 is equivalent to a movable pulley, owing to oil pipe 6 one end is connected on support 5, being then wrapped around on rolling wheel support 8, the other end is connected on fixed support 12, and the movement velocity of impacter 3 is equal to 2 times of rolling wheel support 8, so no matter where impacter 3 moves to, oil pipe 6 is the most just looped around above rolling wheel support 8, has not both had the oil pipe of additional length to fall, and is also unlikely to make oil pipe be in tensioned state.
Tightener sprocket 1 act as regulating the elasticity of chain, more smooth and easy when making chain drive.
