Problems solved by technology
[0002] In the working process of the slewing device of the rotary drilling rig, it is often difficult to increase the braking force during the slewing process for a certain chassis size, which is not conducive to the development of high-power rotary drilling rigs, and for slewing bearings, most of them only use The meshing of gears on the inner ring or the meshing of gears on the outer ring cannot make good use of the strength of the inner and outer rings of the slewing ring.

Embodiment Construction
[0014] The present invention will be further described below in conjunction with embodiment (accompanying drawing):
[0015] Such as figure 1 As shown, the external rotary braking device of the rotary drilling rig of the present invention includes a rotary reducer 1, a rotary support 2, and an outer brake 3, and driving teeth are processed on the inner and outer ring walls of the rotary support 2; The driving teeth of the inner ring of the support 2 mesh with the output gear of the slewing reducer 1 for driving and braking; The output teeth are meshed for braking.
[0016] Further speaking, the opening and closing of the slewing reducer 1 and the external slewing brake 3 are all controlled by the oil pipe of the brake device in the hydraulic system. This structure can ensure that the slewing reducer and the braking device of the external slewing brake are in a non-working state during the slewing process of the whole machine, so that the output gear of the slewing reducer dr...

The invention discloses a rotary drilling rig externally arranged rotary brake device which comprises a slewing bearing, a rotary reduction box and an external brake and is characterized in that driving teeth are processed on the wall surfaces of the inner and outer rings of the slewing bearing; the inner ring driving teeth of the slewing bearing are meshed with the output gear of the rotary reduction box for driving and braking; and the outer ring driving teeth of the slewing bearing are meshed with the output teeth of an externally arranged rotary brake arranged between a chassis and an upper vehicle for braking. According to the rotary drilling rig externally arranged rotary brake device, during the drilling process of a drilling machine, the internal and external teeth can play the braking role, so that the braking force of the drilling machine rotary device can be effectively improved, the drilling perpendicularity of the drilling machine can be effectively ensured, and the working efficiency of the drilling machine is effectively improved; and in addition, construction operation also can be carried out on a hard stratum, so that the construction scope of the drilling machineis greatly increased, and the applicability of the drilling machine to different construction sites is improved.
Description
technical field [0001] The invention belongs to the technical application field of a rotary device for a rotary drilling rig, and in particular relates to an external rotary braking device for a rotary drilling rig which improves the rotary braking capacity of the rotary drilling rig. Background technique [0002] In the working process of the slewing device of the rotary drilling rig, it is often difficult to increase the braking force during the slewing process for a certain chassis size, which is not conducive to the development of high-power rotary drilling rigs, and for slewing bearings, most of them only use The meshing of the gears on the inner ring or the meshing of the gears on the outer ring cannot make good use of the strength of the inner and outer rings of the slewing bearing. Contents of the invention [0003] The object of the present invention is to provide an external rotary braking device for a rotary drilling rig aiming at the technical and functional re...
