Definitions
- the invention relates to an arrangement comprising a rock drilling machine, which is mounted on a carriage supportable to a feed beam of a rock drilling rig.
- the rock drilling machine comprises a gear module and a percussion module, which are arranged on a same axial line and are connected to each other by means of connecting means.
- the invention further relates to a method of mounting a rock drilling machine.
- rock drilling machines are used for drilling bore holes into rock surfaces and soil.
- the rock drilling machine comprises a rotating device for rotating a drilling tool during drilling around longitudinal axis of the drilling tool.
- the rock drilling machine also comprises a percussion device for generating impact pulses to the drilling tool.
- the rock drilling machine is typically connected to a carriage, which is supported to a feed beam of a rock drilling rig.
- An example of such arrangement is presented in patent publication US 2002/084110 A1 .
- axial forces are directed to connecting means arranged between the rotating device and the percussion device.
- the present solutions have shown to contain some problems regarding durability of the connecting means.
- An object of the invention is to provide a novel and improved arrangement and method for mounting a rock drilling machine.
- the arrangement according to the invention is characterized by the characterized features of the independent apparatus claim.
- the method according to the invention is characterized by the characterized features of the independent method claim.
- the rock drilling machine comprises a gear module and a percussion module.
- the gear module comprises transmission elements, such as gear wheels, for transmitting rotation
- the percussion module comprises an impact element, such as a percussion piston, for generating impact pulses.
- the gear module and the percussion module are arranged on a same axial line, and they are pressed axially towards each other by means of first connecting means, which generate a first connecting force.
- first connecting means In addition to the first connecting means and the generated first connecting force, the gear module and the percussion module are pressed towards each other by means of second connecting means, which generate a second connecting force.
- the second connecting means also have another purpose, namely to provide fastening of the rock drilling machine to a support surface of a carriage.
- the carriage comprises a body part, which is an elongated base element arranged longitudinally relative to the rock drilling machine.
- the body part is intended to be arranged below the rock drilling machine and is provided with bearings for mounting it on a feed beam.
- the carriage further comprises two transverse fastenings lugs extending upwardly from the body part, and which lugs are located at a transverse distance from each other. Thereby, a free space exists at a central line of the carriage between the fastening lugs.
- the rock drilling machine is mounted at the longitudinal central line of the carriage, whereby the percussion module is located between the fastening lugs.
- the gear module and the percussion module may be coupled to each other before mounting to the carriage, and the connection to the carriage generates additional connecting forces ensuring that joint surfaces, which are located between the gear module and the percussion module, are properly fastened despite of separating forces directed to the modules during the operation of the rock drilling machine.
- the first connecting means and the second connecting means together ensure that the axial joint surfaces are pressed towards each other despite of operational forces pulling the joint surfaces away from each other.
- the axial forces directed to the connections of the modules are thereby shared with two connecting systems.
- An advantage of the disclosed solution is that one or more joints between the gear module and the percussion module are more secure since two connecting systems are utilized.
- the operational forces that are pulling apart the gear module and the percussion module are received by the first connecting means and the second connecting means, whereby the stresses are shared with two different connecting systems, instead of one. Thanks to this, service life of the connecting means may be longer and failures may be decreased. This has a positive impact to productivity of the rock drilling machine.
- a further advantage is that wear and deformations of joint surfaces of the modules may be decreased because the modules are firmly mounted by means of the disclosed double-connecting system. Since the joint surfaces locating between the gear module and the percussion module are pressed continuously and firmly against each other, no relative movement occurs between opposing joint surfaces and wearing is decreased. Also, since the gear module and the percussion module are pre-coupled to each other by means of the first connecting system, the rock drilling machine may be easily dismounted for service and repair.
- the carriage is provided with one or more axial first support surfaces, which are facing towards the front end portion of the rock drilling machine.
- the percussion module comprises one or more axial second support surfaces, which are facing towards the rear end portion of the rock drilling machine.

- the second connecting force presses the support surfaces against each other and keeps the rock drilling machine firmly connected to the carriage.
- the front directed axial first support surface of the carriage is advantageous since it provides a firm axial element for transmitting front directed feed forces from the carriage to the body of the rock drilling machine.
- the front directed axial first support surface of the carriage may also provide support against rearward directed forces caused by stress pulses reflecting backwards from the drilled material along the drilling tool.
- the feed forces and the reflecting stress pulses do not cause extra loadings to the second connecting means.
- the second connecting means are configured to transmit backward directed forces from the carriage to the body of the rock drilling machine when the rock drilling machine is reversed on the feed beam.
- connection between the carriage and the percussion module comprises axial support surfaces, which are directed in an opposing manner compared to the previous embodiment disclosed above.
- the carriage is provided with one or more axial first support surfaces facing rearward
- the percussion module comprises one or more axial second support surfaces facing forward.
- the support surfaces facing in opposing directions are arranged against each other and are secured by means of the second connecting force.
- the second connecting means are not subjected to extra loading when the rock drilling machine is reversed on the feed beam and the drilling equipment is retracted from the drill hole.
- This solution may be advantageous when long drill holes are drilled vertically and weight of the supported drilling equipment is great, or when the retracting of the drilling equipment is problematic because of any other reason.
- the first and second connecting means comprise several axially directed connecting bolts.
- the use of connecting bolts and screw-fastening is advantageous since they tolerate well fatigue loadings, and also because they are simple and inexpensive.
- the first and second connecting means comprise several axially directed connecting bolts. Furthermore, the first connecting means, i.e. first connecting bolts and the second connecting means, i.e. second connecting bolts are located at different distances from a center line of the rock drilling machine. Thereby, a transverse first distance between longitudinal axis of the first connecting bolts and a central line is minor than a second distance between longitudinal axis of the second connecting bolts and the central line.

- the pin bolts facilitate mounting of the percussion module since they may guide the percussion module during the mounting measures.
- the arrangement comprises several through holes for the second connecting bolts.
- the second connecting bolts pass through first through holes of the first connecting surface of the gear module, through second through holes of the second connecting surface of the percussion module, and further through third through holes of the support surface of the carriage.
